Fig. 1 expresses a close accessory 10 of liquid with 12 and 90 ° of sealing nuts 14 of the close main body of liquid (being connector), and it constitutes according to first embodiment of the invention, and is applicable to the close main body 12 of liquid and is connected.The structure of the close main body 12 of liquid and working method and in U.S. Pat 5,405, the structure of the close connector body of disclosed liquid is identical with working method in 172, and the specification of this patent is together as the application's list of references.For example, with reference to Fig. 9 A, gland 20 that 16, one on the top (being grip portion) that main body 12 has a band strain relief pawl 18 is supported by strain relief pawl 18 and the screw thread 22 that is used to connect main body 12 and sealing nut 14.Main body 12 also has threaded bottom 24, and it is used in the close mode of liquid main body 12 being installed in the housing 26 of electric and/or mechanical device.More particularly, locking nut 28 is screwed in bottom 24, so that main body 12 is installed on the housing 26.In order between main body 12 and housing 26, to realize required liquid seal, on six side's flange 29b of main body 12, annular flange flange 29a is set, when locking nut 28 is screwed in the bottom 24 of main body 12 fully, this flange 29a be suitable for and housing 26 between sealed engagement.In addition, bottom 24 is conical, so that can directly be screwed in the similar tapering screwed hole (not shown) on the housing 26 that is formed on device, connects airtight and closes thereby directly form liquid between bottom 24 and hole.

With reference to Fig. 1-8, sealing nut 14 preferably utilizes injection moulding to make with the nylon of injection stage, the sealing nut has a

base

30,32 and movable hinges 34 of a lid, this activity hinge will cover 32 rotationally and be connected on the base 30, make and cover the 32 moving axis A that can rotate and rotate (seeing Fig. 1 and 4), and should the activity hinge with base 30 with cover 32 and fuse.Base 30 links to each other with the top 16 of main body 12 by screw thread, and press and the similar mode of above-mentioned U.S. Pat 5,405,172 (seeing Fig. 9 B and 9C), cooperatively interact with the strain relief pawl 18 and the gland 20 of main body 12, with the cable 33 of clamping by close accessory 10 extensions of liquid.In this case, base 30 has one to be run through base 30 along its longitudinal axis B and extends (seeing Fig. 3 and 4) so that pass cable 33, and its size and dimension is suitable for removably receiving the vertical passage 36 on the top 16 of main body 12; Be used to push cone-shaped inner surface 38 (see figure 4)s of pawl 18 and gland 20; And be used for base 30 is connected to screw thread 40 (seeing Fig. 6 and 8) on the main body 12.In addition, base 30 has an open trough 42, and this open trough is positioned near the upper end of base 30, and has a level and smooth arc rear surface 44 (seeing Fig. 6 and 8), and this arc rear surface will be discussed hereinafter.But base 30 is provided with the

cavity

46,48 on a pair of outer wall 50 that is formed on main body 12 relative both

sides.Cavity

46,48 comprises the transverse planar wall 46a that is approximately perpendicular to rotating shaft A respectively, 48a and be roughly parallel to the parallel plane wall 46b of rotating shaft A respectively, 48b, (seeing Fig. 1,3 and 4).

Lock tab

52,54 lays respectively in the

cavity

46,48, and respectively from the wall 46a that is in two

rightabout cavitys

46,48 of base 30, the horizontal expansion of 48a place.For the purpose of discussing conveniently hereinafter, make the bearing of trend of

lock tab

52,54 vertical with the direction of the longitudinal axis B of base 30.That is to say that

lock tab

52,54 comprises plane locking surface 52a, the 54a (see figure 4), they lay respectively in the plane of the longitudinal axis B that is approximately perpendicular to base 30.Base 30 also is hexagon, so that utilize conventional instrument, as the spanner (not shown) sealing nut 14 is screwed on the main body 12.

Refer again to Fig. 1-7, lid 32 can be around the rotation axis A that substantially extends perpendicular to the direction of longitudinal axis B, rotate between enable possition and off-position.On the enable possition, lid 32 can fully expose the passage 36 of base 30, so that cable can be roughly to pass sealing nut 14 along the direction that is in substantially parallel relationship to the longitudinal axis B of base 30 to linear state; On off-position, lid 32 covers on the passage 36 of base 30, makes cover 32 pilot cable 33 bendings within it loosely (see Fig. 2,7,8 and 9C).Lid 32 comprises that also is suspended in a lock pawl 56 that covers a side of 32, and is suspended in the lock pawl 58 that covers 32 relative opposite

side.In lock pawl

56,58, form

notch

60,62 respectively, be connected on the base 30 so that will cover 32 in the mode that is fastened.More particularly, the size and dimension of

notch

60,62 is suitable at lid 32 making these two notches receive the lock pawl 52 of base 30 respectively in the mode that is fastened when the base direction is rotated and be pressed on the base 30,54 (that is, at this moment cover 32 in the closed position).In this case,

notch

60,62 has plane locking surface 60a respectively, and 62a is when lock

tab

52,54 when engaging with

lock pawl

56,58 respectively,

plane locking surface

60a, 62a respectively with

locking surface

52a, 54a engages, and covers 32 and remains on (see figure 7) on its off-position thereby make.In addition, when lid 32 was in its off-position,

notch

60,62 all penetrated the inside of

lock pawl

56,58 respectively, so

lock pawl

56,58 surrounds lock tab 52,54 (see figure 7)s.In addition, when lid 32 when being in its off-position, notch 60,62nd, location like this:

i.e. locking surface

60a, 62a is positioned on the plane of cardinal principle perpendicular to the longitudinal axis B of base 30.The width of

lock pawl

56,58 is respectively W1, W2 (seeing Fig. 3 and 4), and when

lock tab

52,54 and

lock pawl

56,58 joints,

lock pawl

56,58 is respectively along the wall 46a that is in substantially parallel relationship to

cavity

46,48, and the direction of 48a is extended.Yet open trough 64 extends to and covers 32 the other end from covering an end of 32.The size and dimension of groove 64 should be able to make this groove match with the groove 42 of base 30, (see Fig. 2 to form an interconnection 68 that is communicated with the vertical passage 36 of base 30,7 and 8), and when lid 32 was connected on the base 30, this passage 68 had a longitudinal axis B longitudinal axis C (see figure 8) at an angle of 90 with respect to base 30.

With reference to Fig. 9 A-9C, in order to use the close accessory 10 of liquid, by locking nut 28 being screwed on the bottom 24 with main body 12, or by bottom 24 directly being screwed in the threaded openings that is formed in the housing 26, and main body 12 is installed on the housing 26 of electric and/or mechanical device.For the lid 32 that is in the enable possition, sealing nut 14 is connected on the top 16 of main body 12 in the mode that is spirally connected loosely.With linear state cable 33 is passed the vertical passage 36 and the main body 12 (seeing Fig. 9 A) of base 30 then.In addition, main body 12, sealing nut 14 and cable 33 can assemble in the above described manner in advance, it are installed on the housing 26 of device again.Secondly, sealing nut 14 is screwed to the top 16 of main body 12 fully, the strain relief pawl 18 and the gland 20 of the base 30 of sealing nut 14 is matched, thereby firmly grasp cable 33 (seeing Fig. 9 B), strain relief also is provided simultaneously in the close mode of liquid.Turn at the close accessory 10 of liquid and to make cable 33 facing to after the housing 26 outside desired positions, lid 32 is fixed in the base 30 with being fastened.More particularly, the

lock tab

52,54 of base 30 is fixed in the

corresponding notch

60,62 of lock pawl 56,58 (seeing Fig. 7 and 9C) with being fastened respectively, covers 32 and is positioned at off-position thereby make.In a manner described, cable 33 is received in the

groove

42,64 of base 30 respectively and is covered between 32, thereby is positioned in the transverse groove passage 68.Therefore, cable 33 forms 90 ° of bendings (seeing Fig. 8 and 9C) near the passage 36 of base 30 and the joint 70 between the interconnection 68, thereby and makes cable send into electric and/or mechanical device with 90 ° of angles.

Be to be understood that the present invention has many than the superior part of prior art.For example because lid 32 rotates, leaves base 30 exposing vertical passage 36, institute so that cable 33 can enter housing 26 and pass the close accessory 10 of liquid by linear state.By this way, sealing nut 14 can make cable 33 enter housing 26 simple and efficiently.But, owing to sentence the mode of sealing and strain relief by main body 12 tight cables 33 at base 30, so in the process of using sealing nut 14, opened unintentionally, also can not damaged sealing and the strain relief function that main body 12 and sealing nut 14 are had even cover 32.In addition, because its crooked level and smooth shape, so when lid 32 when the enable possition moves to off-position, it is crooked in its vicinity that near the curved surfaces 44 that forms joint helps cable 33, and crooked and/or when using the close accessory 10 of liquid at cable 33, this curved surfaces also has avoids the suffer damage function of (i.e. the infringement of the form of cut or cuts that is caused by sharp keen blade or analog) of cable 33 to greatest extent.

Locking mechanism of the present invention also further has the advantage that is better than prior art.For example, because

lock tab

52,54 is with respect to the longitudinal axis B perpendicular positioning of base 30, so

lock tab

52,54 and

lock pawl

56,58 are bonded with each other with vertical direction.That is to say that when

lock pawl

56,58 engaged with

lock tab

52,54 respectively, the locking surface 60a of

lock pawl

56,58,62a laid respectively on the plane of vertical base 30 longitudinal axis B.Therefore, respond the active force in any

lock pawl

56,58 that acts on the external force on the sealing nut 14, its direction all trends towards being roughly parallel to the direction (as the vertical direction of pointing to of arrow D among Fig. 7) of longitudinal axis B.In this case,

lock pawl

56,58 and

lock tab

52,54 have improved the ability that stops their to break away from, and cover 32 resistances that unexpectedly break away from base 30 thereby increased.In addition,, therefore, be applied to when cover on 32, can prevent that

lock tab

52,54 from laterally sliding with respect to lock

tab

52,54 respectively, thereby can further strengthen the ability of prevention disengaging as external force because

lock pawl

56,58

surrounds lock tab

52,54 respectively fully.But, because

lock pawl

56,58 surrounded

lock tab

52,54 fully, thus between

lock pawl

56,58 and

lock tab

52,54, can keep interlocking to engage respectively, even pivot 34 damages or also is like this when fractureing when using sealing nut 14.In such a way, lid 32 can keep and being connected of base 30, thereby and make cable 33 keep the direction at 90 ° of angles, even also be like this when the support structure that provides by hinge 34 is not provided usually.

Lid 32 also has the advantage that other is superior to prior art.For example, open slot 64 makes and covers 32 features with spring-like.Therefore, when

lock pawl

56,58 during respectively with

lock tab

52,54 interlocking, lid 32 can deflection, and supposition is when

lock pawl

56,58 engages fully with

lock tab

52,54 respectively, lid be shaped as normal shape.In this way, lid 32 helps to realize respectively that fastening cooperates between

lock pawl

56,58 and lock tab 52,54.Yet open slot 64 helps to remove used core behind this open slot of die casting from sealing nut 14, is favourable to the die casting process like this.

It should be noted that the present invention can have many remodeling and carry out various conversion.For example, the direction with respect to the interconnection 68 of the vertical passage 36 of main body 12 also can change over other angle (for example 100 °).In addition, base 30 also can be other shape, and is not hexagon.But also available any other the conventional pivot mechanism of movable hinge 34 replaces.Also available any other the traditional locking mechanism of

lock pawl

56,58 and

lock tab

52,54 replaces.In addition, sealing nut 14 can and/or utilize other traditional technology manufacturing with other suitable material.

Figure 10-15 and Figure 16 and 17 express the of the present invention second and the 3rd embodiment respectively.In Figure 10-15 and Figure 16 and 17, represent with identical label with the above-mentioned identical or essentially identical parts among Fig. 1-9C, but all add numeral 100 and 200 respectively for corresponding label.Except exception, the embodiment of Figure 10-17 is identical with the basic skills of the formation of Fig. 1-9C, combination and use.

The close accessory 110 of the liquid that 90 ° of sealing nuts 114 are housed that Figure 10-15 expression constitutes according to the second embodiment of the present invention.The sealing nut 14 of the structure of sealing nut 114, the course of work and use and Fig. 1-9C illustrated embodiment basic identical, difference is as follows: sealing nut 114 has a base 130, on this base, be provided with the cavity 146,148 in a pair of outer wall 150 that is respectively formed at base 130 relative both sides.Lock tab 152,154 is respectively formed in the cavity 146,148, and with opposite direction from base 130 horizontal expansions.Identical with the

tab

52,54 of Fig. 1-9C embodiment, the direction of lock tab 152,154 is perpendicular to the longitudinal axis B of base 130.Sealing nut 114 also covers 132, and it has a pair of from covering the lock pawl 156,158 of 132 two opposite sides suspention.The size and dimension of lock pawl 156,158 should be able to make its respectively with lock tab 152,154 interlocking of base 130, be connected on the base 130 in the mode of being fastened and (see Figure 11,14 and 15) thereby will cover 132.Each cavity 146,148 also comprises the side plane wall 146b that is used for fixing a corresponding lock pawl in the lock pawl 156,158,146c (seeing Figure 10,12 and 15).Can stop lock pawl 156,158 respectively with respect to lock tab 152,154 transverse movements by this way, thereby can strengthen 132 abilities that unexpectedly break away from from the base 130 of covering.But, because the direction of lock tab 152,154 is perpendicular to the longitudinal axis B of base 130, so lock tab 152,154 and lock pawl 156,158 vertically are bonded with each other.In this case, lock tab 152,154 and lock pawl 156,158 have further strengthened the ability of cover 130 unexpected disengagings from the base 130 that stops again.

The close accessory 210 of the liquid that 90 ° of sealing nuts 214 are housed that Figure 16 and 17 expressions constitute according to the third embodiment of the present invention.The sealing nut 14 of the structure of sealing nut 214, the course of work and use and Fig. 1-9C illustrated embodiment basic identical, difference is as follows: sealing nut 214 has the lid 232 that a base 230 and the moving axis A that can rotate rotate.More precisely, base 230 is provided with a pair of cavity 246,248, and they are formed in the outer wall 250 of base 230 relative both sides.Cavity 246,248 comprises the transverse planar wall 246a that is approximately perpendicular to rotation axis A respectively, 248a and be roughly parallel to the parallel plane wall 246b of rotation axis A respectively, 248b.Lock tab 252,254 forms respectively and is positioned in the cavity 246,248, and they extend (be them respectively from the wall 246b of cavity 246,248,248b stretches out at the place) forward from base 230.Be equipped with a pair of on the lid 232 from covering 232 lock pawls 256,258 that hang.The size and dimension of lock pawl 256,258 should be able to make its respectively with lock tab 252,254 interlocking of base 230, be connected on the base 230 in the mode of being fastened thereby will cover 232.The width of lock pawl 256,258 is respectively W1, W2, and when lock pawl 256,258 and lock tab 252,254 engaged respectively, to be roughly parallel to the wall 246b of cavity 246,248, extended respectively by the direction of 248b for lock pawl 256,258.

Figure 18 represents the close accessory 310 of the liquid of another embodiment of the present invention.As previously mentioned, main body 312 has a plurality of flexible pawls 318 that are circular layout and extend with axial direction from the one end.The gland made from the deformable seal material 320 is surrounded (seeing Figure 26) by pawl 318, and gland 320 helps to nestle up the cable or other elongated shape object that remain in the close accessory 310 of liquid and forms liquid seal.Sealing nut 314 tightly is screwed in by the mode that is spirally connected on the screw thread 322 of main body 312, and the conical inner surface 338 (representing with partial sectional view) of sealing nut 314 nestles up pawl 318 and inside extruding pawl 318, the object that is inserted with clamping.As what we understood, accessory 310 on general structure and function with inventor invention, and transferred assignee's United States Patent (USP) U.S.5,405, similar shown in 172 with the accessory of describing, this patent can be used as list of references of the present invention, and it has provided the dependency structure of the close accessory of liquid and the instruction of manufacture method.However, hereinafter will describe the embodiment of the invention shown in Figure 18-29 and have many novel features.Should be further understood that the sealing nut 314 shown in Figure 18-29 can substitute with the Seal of Cables nut that keeps an angle of 90 degrees, these 90 jiaos identical with the sealing nut of also describing hereinbefore shown in Fig. 1-17 14.

Figure 18, the novel cup seal flange 331 of 21,26 and 28 expressions, it just had the cup-shaped of hollow before accessory is fixed to mounting panel or housing.When accessory is screwed into installation surface or draws when leaning against on the installation surface, flange 331 flattens (seeing Figure 28), and the material of accessory has enough elasticity, so that cup-shaped flange 331 flattens.When flange flattens, the air or the aqueous vapor that are collected between cup-shaped flange 331 and the installation surface are discharged.Because cup-shaped flange 331 has elasticity and has and turns back to its original cup-shaped trend, so flange 331 can provide irregular (as: not straight or deflection) installation surface can be guaranteed perfect sealing like this.When flattening, flange 331 launches, thereby bigger sealing surfaces is provided.Therefore, cup-shaped flange 331 also can provide effective seal under the situation of not using liner or other sealing hardware.

Figure 19 represents to be in the upper end 370 of the roughly triangular in shape or wedge shape of each pawl 318 end.The triangle of pawl 318 upper end 370 is spaced from each other and radially extends internally, and has a triangle inboard 372 simultaneously, it and the excircle general tangential of cable passage 336 by main body 312.The curve of the triangle outside 374 preferably curvature with the conical inner surface 338 of sealing nut 314 is approximate, thereby helps nut 314 to rotate with respect to pawl 318.Medial side 376 is linked to be triangle with other both sides, and after accessory 310 was compacted, this medial side 376 rubbed mutually with the inner edge 372 of adjacent upper end 370, more fully is described below:

Figure 20 represents to be in the profile of the pawl 318 of triangle upper end 370 lower positions.Pawl 318 has a section thin with respect to triangle upper end 370 as can be seen, and roughly flattened into parallelogram, this parallelogram has two relative arc limits, and have and form extending transversely part 378,380 angle, this extending transversely part is overlapping with the prolongation of adjacent pawl 318.Thisly overlappingly provide perimeter support, when sealing nut 314 is tightened, make pawl keep flexible simultaneously and compile to the center to gland.

Figure 21 represents to be arranged on the groove 382 that is used to hold gland 320 in the main body 312 of accessory 310.Groove 382 is positioned at the end near conical ring seat 384, this 384 section start that is formed near or the pawl 318 of base.Cone tilting in main body 312 when seat 384 radially stretches out than the depths.Groove extends towards triangle pawl end 370 directions vertically from the outer peripheral edges of cone seat 384.Be understood that from Figure 21 the downside of each pawl end 370 is all cut sth. askew respectively, so that form identical updip shape seat 386, it is roughly the same with interior 384 direction, but the inclination angle is bigger.With reference to Figure 26, as can be seen, the shape of gland 320 is the compensation to the shape of groove 382, and wherein gland is surrounded tightly, also is like this even be in not under the tight condition at accessory.

The sealing nut 314 of Figure 22-24 expression one embodiment of the invention, it has novel ratchet lock 388, and this ratchet lock 388 stretches out from inner wall surface, and radially extends towards interior center to nut.The zoomed-in view of the ratchet lock 388 of Figure 23 shows that this lock has the directivity of similar ratchet, and this ratchet lock points to counterclockwise as shown in FIG..Counter clockwise direction shown in the figure is applicable to accessory 310, on accessory sealing nut 314 along clockwise direction (being the right-hand thread direction) fastening.The opposite direction of lock 388 is applicable to counterclockwise fastening left-hand thread.At work, when making sealing nut 314 fastening, lock 388 is skipped the edge of pawl 318.Why can be like this since lock 388 and pawl 318 have flexible, when lock 388 when pawl 318 is crossed, lock and pawl generation strain.In order to prevent unintentionally accessory to be got loose, when rotating on lock 388 direction pointed along them, lock 388 is hooked in and/or abuts against on the edge of pawl 318, rather than crosses them.

Figure 24 represents to lock 388 and is on the reposition of sealing nut 314.More particularly, lock extends between screw thread and conical inner surface 390 from the inner circumferential surface 390 of sealing nut.As being advised in normal commercial Application, locating the benefit that obtains like this by lock 388 is can avoid because lock 388 directly is in the excessive mechanical deformation that causes on the trochoidal surface 338.Be positioned on the inner surface 338 if lock 388, then when accessory was tightened, they can be subjected to crooked and needed friction of locating detent and displacement force.These power that stand in the zone of trochoidal surface 338 must must be enough to make the distortion of lock 388 to surpass its elastic limit greatly, thereby make it to lose efficacy.Therefore, lock 388 is positioned at avoids still acting on the lower position place of pawl simultaneously along its length in the zone that between sealing nut 314 and pawl 318 mechanical connection lost efficacy, can keep locking 388 shape and function like this, even after fastened, also be like this.Lock 388 of the present invention can with existing locking device, as be positioned at projection on the trochoidal surface of sealing nut 314 or pit etc. and use together.

Figure 25,26 and 27,28 is respectively accessory is not tightening and front view and the cutaway view under the tight condition.Figure 29 is illustrated in never tight condition in tightening change procedure, the motion conditions of triangle shaped ends 370.From to the comparison of Figure 25 and 27 as can be seen, the triangle shaped ends 370 of accessory 318 originates in its inner edge 372, this inner edge is tangent with interior all chambeies of gland 320 substantially, the outer arcuate limit 374 of triangle shaped ends 370 roughly with circular cone inner surface 338 and surface 390 between intersection limit round consistent.Triangle shaped ends 370 is spaced from each other.After sealing nut 314 is tightened (as shown in figure 27), inner edge 372 is last tangent with a very little circle approx.This motion with triangle shaped ends 370 identical (as shown in figure 29) that is to say that when tightening sealing nut 314, triangle shaped ends 370 is inwardly rotated towards the center of accessory 310.Triangle shaped ends 370 is inwardly changeed makes the end extend bigger distance to the axis of accessory 310, so that they cross the gland 320 and the cable 392 of directly nipping, thereby is fixed in the accessory.Accessory 310 is gone up usually and is made by the plastics of tough and tensile densification.On the contrary, gland 320 is made as rubber usually by more pliable and tougher material.Therefore, the present invention uses sharper keen " tip " (" points ") on the triangle shaped ends of the pawl 318 of rigidity more, catching cable 392, and softer, the more level and smooth and deformable gland 320 that can not cause the pawl extruding to contact with cable.As a result, the external insulation layer of going into softer cable 392 " is stung " in the thicker rigid triangle end 370 of pawl 318, thereby can clamp cable effectively.It may be noted that also triangle shaped ends 370 is thicker than the remainder of pawl 318.The distribution of this material can make pawl 318 bendings (as shown in figure 28), is strengthened in the end 370 that forces itself and cable 392 more closely to contact by sealing nut 314.Figure 29 represents when sealing nut 314 is tightened, pawl 318 aduncate situations.This curving inwardly also shows in Figure 28, and this figure further expresses triangle shaped ends 370 and also is bent downwardly simultaneously.The consequence of this while bending is to promote gland 320 downwards, makes gland near following 384 of taper and push it, makes it near cable.As shown in figure 28, when gland 320 was pushed, it played a sealing device near cable 392 and seat 384.By this way, gland 320 can remain in the accessory 310 reliably, can be pushed with suitable direction again, thereby necessary dual-seal function is provided.

As can be seen from Figure 27, because triangle has two very little acute angles and a corresponding uncovered third angle, so triangle shaped ends 370 is longilineal.Therefore, the length on inner edge 372 and middle limit 376 is longer.As shown in figure 27, triangle shaped ends 370 is pulled to together, and the inner edge 372 of adjacent triangle shaped ends 370 and middle limit 376 are contacted.Because contact area is bigger, has the larger area triangle shaped ends so triangle shaped ends 370 can be pressed over another, and utilizes friction that they are locked together.Because triangle shaped ends 370 is rigidity, and their motion is owing to being subjected to strict restriction with adjacent end portion 370 and contacting of sealing nut 314, so be difficult to make by the power that for example applies to cable 392 the centre bore expansion of the accessory of tightening 310.The large-size of triangle shaped ends 370 can guarantee that its tip can surpass gland 320 and extend quite long distance, and can make its cable 392 of nipping dearly.Because the radical length of triangle shaped ends 370 has partly limited possible radial displacement, the effective dimensions of cable passage by accessory 310 determined in this displacement, so triangle shaped ends 370 is big more, and can be just big more by the cable dimension scope that accessory holds.

Be appreciated that the foregoing description only illustrates, those skilled in the art can do various conversion and improvement under the situation that does not break away from spirit of the present invention and protection range.These conversion and improvement should be included in the protection scope of the present invention that is limited by claim of the present invention.
