Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric wire cover and a connector provided with the electric wire cover.
[0002]
[Prior art]
When an electric wire led out from the housing is bent and arranged in an L shape, an electric wire cover is used, and examples thereof include those shown in FIGS. The electric wire cover 100 is formed by connecting a pair of halves 101A and 101B having an L shape with hinges 102, and wrapping the electric wires 103 by rotating the halves 101A and 101B around the hinges 102 as fulcrums. It is supposed to be united. The halves 101A and 101B are formed with inclined portions 104A and 104B in the form of obliquely cutting portions that are the outer sides of the bending. By forming the inclined portions 104A and 104B, for example, downsizing can be achieved. It is possible.
[0003]
In the electric wire cover 100, as one means for holding the pair of halves 101A and 101B in a combined state, a bending locking piece 105 protruding toward the other half 101B is formed on one half 101A. The locking projection 106 is formed on the outer surface of the other half body 101B. In a state where both the halves 101A and 101B are combined, the bending locking pieces 105 and the locking projections 106 are locked so that the halves 101A and 101B are locked so as not to be detached.
[0004]
In addition, as an electric wire cover which united the half-split body, there exist some which are indicated by patent documents 1 grade.

[Problems to be solved by the invention]
In the case of a structure in which the inclined portions 104A and 104B are inclined with respect to the rotation center axis 107 and the inclined portions 104A and 104B are provided with the bending locking pieces 105 and the locking protrusions 106, originally. As shown in FIG. 11, the hinge 102 (rotating) of the projecting end edge of the bending locking piece 105 is formed, although the bending locking piece 105 has to overlap the outer surface side of the counterpart half body 104B. There is a possibility that the end portion 105a on the side close to the center) will sink into the inner surface side of the other half half body 104B, and the two half bodies 101A and 101B may not be correctly combined.
[0007]
This is because, when viewed in parallel with the rotation center axis of both halves 101A and 101B, the radius of the arc serving as the rotation trajectory of the protruding end portion 105a of the bending locking piece 105 is the base of the bending locking piece 105. Since the end 105b is larger than the arc that forms the rotation trajectory of the end portion 105b, the protruding end portion 105a of the flexure locking piece 105 is radially outward from the outer surface of the inclined portion 104B with respect to the counterpart half body 101B, that is, inclined. This is caused by the approach from the inner surface side of the portion 104B.

[Action and effect of the invention]
[Invention of Claims 1 and 3 ]
In the case where the bending locking piece protrudes toward the second half body from the inclined portion with respect to the rotation center of the half body, the bending locking piece is the first in the process of combining the two half bodies. Although it is feared that it will sink into the inner surface side of the half halved body, according to the present invention, even if the bending locking piece is displaced to the inner surface side of the second half body, the bending locking piece abuts against the restricting portion. Therefore, it is possible to prevent diving into the inner surface side. Thereby, while being able to unite both halves reliably, the bending locking piece and the locking projection can be reliably locked and both halves can be held in the combined state.
[0014]
Then, the bending locking piece that has come into contact with the restricting portion is drawn from the inner surface side to the mating surface side, that is, the outer surface side by the guide surface, so that the bending locking piece sinks into the inner surface side of the second halved body. Is reliably prevented.
[Invention of Claims 2 and 4 ]
The inner surface portion of the guide surface is raised, and the outer surface portion of the guide surface is notched, so the height difference between the inner and outer ends of the guide surface is enlarged to increase the height of the guide surface. The gradient can be increased. Thereby, the reliability of the function which guide | induces a bending locking piece to an outer surface side becomes high.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
[Embodiment 1]
A first embodiment of the present invention will be described below with reference to FIGS.
The connector according to the present embodiment includes a housing H that houses a plurality of terminal fittings (not shown), and a substantially L-shaped cylindrical wire cover C that is attached to the housing H. From the rear end face of H, the electric wires W connected to the respective terminal fittings are led backward (rightward in FIGS. 1 and 2). The derived electric wire W is surrounded by the electric wire cover C, bent downward in the electric wire cover C, and protrudes downward from the electric wire cover C.
[0016]
The electric wire cover C is made of a synthetic resin, and is composed of a single component in which the first and second halves 10 and 20 are connected by a hinge 30. The hinge 30 has a thin plate shape. When the first half 10 is inverted while the hinge 30 is bent in a substantially U shape and is joined to the second half 20, the two halves 10, 20 An electric wire cover C having a substantially L-shaped cylindrical shape is formed. Thus, when the two halves 10 and 20 are rotated and united, the substantially central position between the halves 10 and 20 in the hinge 30 is the rotation center shaft 31, that is, the first half. It becomes the fulcrum of 10 inversions. Moreover, the both edge parts along the front-back direction of the hinge 30 are connected with the edge part used as an upper edge in the combined state of both the halves 10,20.
[0017]
The first halved body 10 has a flat plate shape as a whole, and is substantially relative to the hinge 30 in the unfolded state shown in FIGS. 2 and 3 (the state immediately after molding before combining the halves 10 and 20). It is connected at a position that is flush (position close to the mating surface 14 with the second half 20). A semi-cylindrical portion 11 that constitutes a lead-out port for the electric wire W is formed at a position that becomes a lower end portion on the rear end side in a combined state with the second half-divided body 20 (a state that is vertically inverted with respect to the deployed state) The substantially half-cylindrical portion 11 is formed with a pair of front and rear plate-like elastic locking pieces 12 projecting toward the second half 20 (approximately perpendicular to the plate surface of the first half 10). Further, a plate-like elastic locking piece that protrudes from the inner edge of the mating surface 14 toward the second half 20 at the front edge of the first half 10 at the front end (the side close to the hinge 30). 13 is formed, and a receiving portion 15 corresponding to the elastic lock piece 13 with the mating surface 14 interposed therebetween is formed to protrude toward the second half body 20 side. A plate-like elastic locking piece 16 that protrudes toward the second half 20 is formed at the lower edge (the side far from the hinge 30) of the front end of the first half 10. The pressing portion 17 corresponding to the elastic lock piece 16 with the mating surface 14 interposed therebetween is formed so as to protrude toward the second half body 20 side.
[0018]
The second half body 20 has a box shape as a whole, and the upper wall portion 21 and the hinge 30 are connected at a substantially right angle in the unfolded state, and the connecting position is the first half portion of the upper wall portion 21. The position is close to the mating surface with the split body 10. A semi-cylindrical portion 23 that constitutes a lead-out port for the electric wire W is formed at a position that becomes the lower end on the rear end side in the combined state with the first half-divided body 10. A pair of locking protrusions 24 are formed on the side surfaces. In addition, a lock protrusion 25 is formed on the inner surface of the upper wall portion 21 (on the side close to the hinge 30) at the front end portion of the second half body 20, and the lower side (hinge) at the front end portion of the second half body 20. A lock protrusion 27 is formed on the outer surface of the wall portion 26 on the side far from the wall 30.
[0019]
The electric wire cover C formed by combining the two halves 10 and 20 has a cylindrical shape bent into an L shape, and each of the halves 10 and 20 has an outer side of the bend. The inclined edge portion 40 (inclined portion which is a constituent element of the present invention) and the inclined wall 45 (in the present invention) in a form in which the portion is cut at an angle of about 45 ° (a form in which it is inclined downward in the combined state). The slanted portion) which is a constituent requirement is formed. The rear end of the hinge 30 is located in the vicinity of the upper end of the inclined edge 40 and the inclined wall 45.
[0020]
The slanted edge portion 40 of the first half 10 is formed with an elongate mating surface 41 along the outer edge thereof and parallel to the plate surface of the first half 10 so as to face the second half 20. In addition, a bending engagement piece 42 having a substantially rectangular shape and a substantially flat shape protruding from the outer edge of the mating surface 41 to the second half 20 side (substantially perpendicular to the plate surface of the first half 10) is formed. Has been. The bending locking piece 42 is parallel to the outer edge of the inclined edge portion 40, and one side serving as a base end portion thereof is along the outer edge of the inclined edge portion 40. Therefore, the bending locking piece 42 is in an oblique direction with respect to the rotation center axis 31 of the half body 10. Further, the distance from the projecting end portion 42 a of the bending engagement piece 42 to the rotation center shaft 31 (the radius of the arc of the rotation locus drawn by the projecting end portion 41 a) is rotated from the base end portion 42 b of the bending engagement piece 42. It is larger than the distance to the moving center axis 31 (the radius of the arc of the turning locus drawn by the base end portion 42b). A locking hole 43 that is opened in a square shape is formed in the bending locking piece 42, and the bending locking piece 42 has an outer side with its base end portion 42 b (the outer edge of the inclined edge portion 40) as a fulcrum. It can be elastically bent toward the side that is separated from the first half 10 and the side that is separated from the outer surface of the second half 20 in the combined state.
[0021]
Further, the first half body 10 is formed with a positioning portion 44 that protrudes in the same direction as the bending locking piece 42 from a position along the inner edge of the mating surface 41 of the inclined edge portion 40. The positioning portion 44 is positioned so as to correspond to the edge portion on the opposite side of the hinge 30 in the bending locking piece 42, and the protruding end edge of the positioning portion 44 is on the outer side (the bending locking piece 42 side). ) Is formed on the guide surface 44a.
The inclined wall 45 of the second half body 20 is formed with a locking projection 46 protruding from the outer surface of the inclined wall 45. The locking projection 46 has a square shape so as to correspond to the locking hole 43 of the bending locking piece 42. In a state where both the halves 10 and 20 are combined, the locking projections 46 are fitted into the locking holes 43 of the locking pieces 42, and the halves 10 and 20 are relatively displaced in the separating direction by this fitting. (Turning) is restricted.
[0022]
Now, as described above, the halves 10 and 20 have the inclined edge portion 40 and the inclined wall 45 in the oblique direction with respect to the rotation center axis 31, and the bent engagement pieces are bent on the inclined edge portion 40 and the inclined wall 45. In the case of the electric wire cover C provided with 42 and the locking projection 46, the rotation of the protruding end portion 42a of the bending locking piece 42 when viewed in parallel with the rotation center axis 31 of both halves 10 and 20 is shown. Since the radius of the arc serving as the moving locus is larger than the arc serving as the turning locus of the base end portion 42b of the bending locking piece 42, the bending locking pieces 42 are used when the halves 10 and 20 are combined. A corner portion 42c of the protruding end portion 42a closer to the hinge 30 (the rotation center axis 31) is radially outward from the outer surface of the inclined wall 45 with respect to the second half 20, that is, the inclined wall 45. It approaches from the inner surface side (diagonal lower left side in FIG. 2). Therefore, the corner portion 42c of the projecting end portion 42a of the bending locking piece 42 is the second half-divided body 20 even though the bending locking piece 42 originally has to overlap the outer surface side of the inclined wall 45. There is a concern that it will sink into the inner surface of the inclined wall 45.
[0023]
As a countermeasure, the present embodiment has the following structure. That is, the inclined wall 45 of the second halved body 20 extends toward the inner surface side of the inclined wall 45 from a region corresponding to the bending locking piece 42 on the mating surface 47 with the first halved body 10. The form regulation part 48 is formed. The restricting portion 48 has a form protruding from the inner surface of the inclined wall 45, that is, a form along the inner surface of the inclined wall 45. When viewed at a substantially right angle to the mating surface 47, the restricting portion 48 has a substantially square shape and is disposed at a position shifted to the hinge 30 side with respect to the locking protrusion 46. That is, with the mating surface 47 interposed therebetween, the end portion on the hinge 30 side of the locking projection 46 corresponds to the end portion on the opposite side of the hinge 30 in the restricting portion 48. In addition, the restricting portion 48 is disposed at a position deviating rearward from the connecting region between the hinge 30 and the halves 10 and 20 in the front-rear direction. In the state in which the halves 10 and 20 are combined, the positioning portion 44 of the first halved body 10 comes into contact with the restricting portion 48 from the side opposite to the hinge 30.
[0024]
Further, the restricting portion 48 is formed with a bulging portion 49 in a form that swells toward the first half 10 from the mating surface 47 of the inclined wall 45. A cutout portion 50 is formed across the outer surface of the inclined wall 45 so as to be cut out in a generally tapered shape or a substantially arcuate shape. A region extending from the raised portion 49 to the cutout portion 50 is a guide surface 51 having a downward slope from the inner surface side of the inclined wall 45 toward the mating surface 47 side (outer surface side). Further, the notch 50 is formed not only in a region corresponding to the restricting portion 48 but also so as to extend along the mating surface 47 to a region on the opposite side of the hinge 30 from the restricting portion 48.
[0025]
Next, the operation of this embodiment will be described.
When the two halves 10 and 20 in the unfolded state are combined, the first halves 10 are rotated so as to be reversed downward with the hinge 30 as a fulcrum. At this time, the rotation center shaft 31 is located on the hinge 30. When the first half 10 is rotated by approximately 45 °, as shown in FIG. 6, the corner 42 c of the protruding end edge 42 a of the bending locking piece 42 comes into contact with the restricting portion 48. Since the restricting portion 48 is formed so as to protrude inward from the mating surface 47 of the inclined wall 45 of the second half 20, the corner portion 42 c of the bending locking piece 42 is displaced toward the inner surface side of the inclined wall 45. Even if it approaches, it does not dive into the inner surface side of the inclined wall 45 as it is. In addition, the abutting surface of the bending locking piece 42 in the restricting portion 48 is a guide surface 51 that is inclined downward from the inner surface side to the outer surface side of the inclined wall 45, so that the first half body 10 is replaced with the second half. When a pressing force for approaching the split body 20 is applied, the bending locking piece 42 slides on the guide surface 51 toward the outer surface side of the inclined wall 45 due to the inclination of the guide surface 51. Thereby, the bending locking piece 42 can reach the locking projection 46 by slidingly contacting the outer surface of the inclined wall 45.
[0026]
When the first half 10 further approaches the second half 20, the flexure locking piece 42 elastically bends outward and climbs over the locking projection 46, so that both halves 10, 20 are in the normal combined state. Then, the bending locking piece 42 is elastically restored and the locking projection 46 is fitted into the locking hole 43. Due to the engagement between the bending engagement piece 42 and the engagement projection 46, the halves 10, 20 are locked in a combined state in which the mating surfaces 41, 47 are opposed to or in contact with each other.
When the bending locking piece 42 starts to contact the locking projection 46, the guide surface 44a of the positioning portion 44 contacts the inner edge of the mating surface 47 of the inclined wall 45, so that positioning is performed by the inclination of the guide surface 44a. The portion 44 and the bending locking piece 42 are guided to the inner surface side of the inclined wall 45. That is, since the force in the direction of pressing against the outer surface of the inclined wall 45 is applied to the bending locking piece 42, the bending locking piece 42 and the locking projection 46 can be reliably locked.
[0027]
In the state in which the halves 10 and 20 are combined, the elastic lock pieces 12, 13, and 16 are locked to the lock protrusions 24, 25, and 27, respectively, so that the halves 10 and 20 are prevented from being detached. Is done. The elastic lock piece 13 and the receiving portion 15 of the first half 10 sandwich the upper wall portion 22 of the second half 20 inward and outward, and the elastic lock piece 16 and the holding portion 17 are in the second half. The lower wall portion 26 of the split body 20 is sandwiched inward and outward.
As described above, in the present embodiment, when the halves 10 and 20 are combined, even if the bending locking piece 42 is displaced toward the inner surface side of the inclined wall 45 of the second half 20, the bending locking is performed. Since the piece 42 is prevented from entering the inner surface side by abutting against the restricting portion 48, both the halves 10 and 20 can be surely united, and the bending engagement piece 42 and the engagement projection 46 can be combined. Can be securely locked to hold the halves 10 and 20 in the combined state.
[0028]
Further, since the bending locking piece 42 that has come into contact with the restricting portion 48 is guided by the guide surface 51 from the inner surface side of the inclined wall 45 toward the mating surface side, that is, the outer surface side, the bending locking piece 42 is in the second half. It is reliably prevented from entering the inner surface side of the split body 20.
Further, the inner surface portion of the guide surface 51 is raised, and the outer surface portion of the guide surface 51 is notched, so that the height difference between the inner and outer ends of the guide surface 51 is enlarged. Thus, the gradient of the guide surface 51 can be increased. Thereby, the reliability of the function which guides the bending locking piece 42 to the outer surface side is high.
