ANDRE W W YZE/VBEEK ATTO R United States Patent ElsMlNAL ASSlEMlBLY HANHNG QGNBUQTUR Plllfi AND CGNNECTUR BLGCK Wyzenheelr, Cincinnati, one assignor to Fnsite Corporation, Qincinnati, tibia, a corporation of fibrin Filed Jan. 1'7, i962, Ser. No. 166,747 16 Claims. (ill. 339--l7d) This invention relates to electric terminals, and more particularly to terminals of the type which include one or more conductor pins having intermediate portions which project through and are secured to a metallic body portion by means of a glass-to-rneta1 seal for disposing the terminal ends of the conductor pins on opposite sides or" the body portion.

A prime requisite of the subject terminal is that the conductor pins be electrically insulated from and hermetically sealed to the body portion and that an optimum lair path be established and thereafter maintained between adjacent portions of the pins and opposite sides of the body.

eretofore the air path between the conductor pins and body portion of such terminals has been effected by frangible substances such as, by way of example, glass, or the like bonded to the body and extending outwardly therefrom along said pins. Such means have been highly effective and produce a highly eficient terminal as initially manufactured; however, such terminals have been subject to the inherent disadvantage that if roughly handled during installation, or if the pins thereof are bumped or bent after installation, the bond between the pins and body is likely to be broken accompanied by an impairment of the initial and highly essential moisture barrier between the sealed elements with the result that the designed air path of the terminal will be seriously impaired and shortened whereby to render the terminal ineffective and ossibly dangerous for its intended use.

One of the primary objects of the present invention is to provide a terminal assembly wherein resilient means, characterized by their dielectric and moisture-barrier characteristics, are utilized for providing the desired air path between the pins and one side or face of the body portion.

Another object of the invention is to provide a terminal having the hereinabove described characteristics, wherein the conductor pins are rigidly secured to portions of the metallic body by means of a glass-to-metal seal which is limited in area in the sense that it does not project from or beyond that face of the body portion to which the resilient member is secured.

Still another object of the invention is the provision of a terminal having the hereinabove described characteristics wherein a resilient insulator is bonded to that face of the body beyond which the glass-to-meta-l seal does not project, said insulator including outwardly projecting protuberant portions bonded to the conductor pins for defining a predetermined air path between adjacent portions of said pins and body member.

Another object of the invention is to provide an airtight electrical terminal for use in conjunction with hermetically sealed devices wherein leakage into or from such devices, by way of the terminals, is effectively precluded.

Another object of the invention is to provide an improved glass-to-metal terminal for installation using modern mass production electric welding techniques.

Another object of the invention is to provide a connector block for co-operation with the conductor pins of a terminal wherein the connector block includes simplitlecl means for securely though releasably efiecting an electrical connection with the conductor pins of the terminal.

ice

Still a further object of the invention is to provide a new and novel terminal body structure and process for producing same, in which the terminal body includes conductor pins which are initially secured to the terminal body in spaced insulated relationship therewith by fusion of a glass bead interposed between adjacent portions of the body and pin.

These and other objects are attained by the means described herein and as disclosed in the accompanying drawings, in which:

FIG. 1 is a side elevational view, partly in section, of a terminal embodying the teachings of the present invention associated with the wall of a compressor housing or the like.

FIG. 2 is a top view of hte assembly of FIG. 1.

FIG. 3 is a view similar to FIG. 1, illustrating a modification of the terminal assembly.

FIG. 4 is a top view of the assembly of FIG. 3.

FIG. 5 is a view in elevation of the outer face of a connector block embodying the teachings of the present invention for association with the terminal of FIGS. 1 and 3.

PEG. 6 is a view in elevation of the inner face of the connector block of FIG. 5.

FIG. 7 is a vertical section of the terminal of FIG. 1 operatively associated with the connector block of FlGS. 5 and 6.

With particular reference now to FIGS. 1, 2 and 7, the nuioral ill denotes generally the supporting wall or housing of a chamber, compressor shell or other device with which the subject terminal is associated.

As best illustrated in FIG. 7, the numeral 12 denotes generally the metallic shell or terminal body which includes a side wall 1 .6 and an end wall 18 having inner and outer

axial faces

17 and 19, respectively. The inner end of the side wall has been illustrated as terminating in an outturned peripheral mounting flange 2t Conductor pins denoted by the numeral 24 are disposed in concentric alignment with a collar or socket 30 struck inwardly from end wall 18 of the terminal body. Preferably the conductor pins comprise a copper core 26 suitably sheathed as at 28.

The conductor pins 24 may be permanently secured relative to the terminal body by means of a glass seal 34 which is fired whereby to effect a glass-to-metal seal with the inner face 32 of sockets 3t? and with adjacent portions of the outer surface of the intermediate portions of the pins.

In the preferred embodiment of the invention, the

glass sealing element 34 extends along the pins beyond peripheral edge 31 of sockets 36 as at 36, tapering from a maximum diameter :at 32 to a minimum diameter at 37. This provides an efiicient glass-to-metal seal which defines an adequate air path between said pins and adjacent portions of the metallic body.

It should be noted that the forward face or end 35 of the fused glass member 34 is substantially flush with the plane of the forward, or outer face 19 of the body memher; that is, the fused glass member does not project any substantial distance forwardly of face 19, whereby the rigid glass-to-rnetal "seal is located rearwardly of the forward front or outer face 1h of the body member.

After the conductor pins 24 have been rigidly affixed to the body member by reason of the glass-to-metal seal, a resilient insulatordenoted generally by the numeral 33 is applied to the forward or outer face 19 of end wall, and 'to portions of the connector pins adjacent thereto.

The resilient insulator includes a base or disk portion 459 and integral protuberant bushings 42.

Uniformly satisfactory results have been obtained in those instances in which insulator 38 has been fabricated from silicon rubber of the type which is capable of being vulcanized at room temperatures such as, by Way of example, the product manufactured by General Electric Company and merchandised under the trademark or symbol R.T.V.

Production on a commercial scale has been attained by utilizing suitable molds, each having a cavity defining base 40 and the protuberant bushings 42 of an insulator 38. After such a mold has been suitably associated with face 19 of base 18 of the terminal body, and to pins 24 thereof, the cavity of the mold may then be filled such as, by way of example, by injection with a semi-liquid catalized silicon rubber compound, and subjected to low temperature baking, in the neighborhood of 150 F., to accelerate the vulcanizing process and reduce the in-moldtime. After the mold has been stripped from the nowformed insulator 38, the terminal assembly may be aircured for a suitable period of time for providing a resilient insulator which is tenaciously bonded directly to outer face 19 of the body member, outer face 35 of the fused glass seal 34, and the adjacent areas of the intermediate portions of the conductor pins 24. The protuberances 42 establish and define an adequate air path between pins 24 and adjacent portions of the body.

One of the important and essential characteristics of insulator 38 is that the bond made with the pins, glass seal, and body member will remain intact, secure and unbroken even though subjected to flexing or distortion from external sources; or deflection incident to bending of those portions of the pins which projects outwardly from face 19 of the body members. By thus providing a tenacious seal between the insulator member 38 and the other portions of the terminal, an ideal moisture barrier is provided of such a character as to resist rupture or failure incident to relative movement of the insulator with respect to the body member.

The inner ends of the conductor pins may be provided with spade conductors for facilitating the making of an electrical connection with a prime mover, or the like, disposed within or interiorly of a housing of which wall ii) forms a part. Connector elements 52 are secured to and carried by the terminal portions of the conductor pins which project outwardly beyond the forward end 43 of bushings 42.

As best illustrated in FIGS. land 3, each of the connector elements 52 includes a lower end 54-, a notched intermediate portion 55, and an outer end 56 having a slot 58 therein. The lower end 54 of each connector element is fixedly mounted to a conductor pin such as by means of spot welding, or the like, with lower edge 57 of the notched intermediate portion 55 disposed in substantial alignment with the outer end of its respective pin, and with the upper edge 59 of the notched portion spaced outwardly thereof.

The terminal body 32 may be fixedly and rigidly installed by inserting the forward portion thereof through a round aperture 22 pierced through Wall ill for disposing the periphery of the inner side of the aperture in sealing engagement with mounting flange 2d of the terminal body, after which the parts may be permanently secured together by means of a weld 23.

When thus mounted, the interior of the terminal body and those ends of the conductor pins to which connectors 50 are secured will be disposed interiorly of the housing or chamber of which wall forms a part. The lower portions of the pins which project outwardly from end wall 13 are encased within resilient insulator The primary distinction between the terminal of FIGS. 1 and 3 resides in the construction of the body member; in FIG. 3 the conductor pins 24 are secured to a substan tially fiat, thick mounting plate 12% by glass sealing means 134.

The body member 1259 includes aninner face 117 having an annular recess 131 for the reception of an G-ring Ml which is sealed against the outer face ldl of wall to which the terminal is securely though releasably anchored by means of fasteners, such as bolts 161, which project through axially aligned openings llil and 181 in plate and wall It), respectively.

With reference now to FIGS. 5 and 6, the numeral 7% denotes generally a connector block fabricated from a suitable phenolic material to provide a substantially solid central body portion 72 having an inner face ii provided with a plurality of sockets '74 corresponding in location and number to the conductor pins 24 of the terminals of FIGS. 1 and 3. in the preferred embodiment of the invention, each of sockets 74 is larger both in transverse dimension and in depth than protruberant bushings 42., whereby each of said bushings will be loosely received within a socket 74 with a surrounding air gap, as illustrated in FIG. 7.

Body portion 72 is also provided with through apertures 76 which are formed therein and comprise a partial continuation of the sockets 74-. The configuration of apertures '76 is irregular in outline to provide an elongate slotted portion 78 for the reception of lower end 54 of a connector strip 52, and a communicating groove 3% in a side of the slot to loosely receive the outer end of its associated terminal pin 24.

The outer face 77 of block 7d is provided with conductor receiving channels 82 formed therein and extend ing outwardly with reference to the central portion of the block.

The conductor receiving channels 82. intersect the outer ends of the sockets 75, whereby on assembly of the terminal body and connector block the free outer ends as of the connector strips may be bent at substantial right angles with their respective conductor pins about notched portions 55 for disposing the slotted portions 53 of outer ends 56 each in overlying relationship with the outer end of an internally threaded brass bushing 9t secured to and carried by body portion 72 of the plug.

A ring-tongue connector clip 93 of a conductor wire 94- may be secured in electrical contact-making-relationship with connector strips 52 by means of a screw or other fastening means @6 as illustrated in FIG. 7.

With particular reference now to FIG. 5, it will be noted that at 76A the forward end of the socket as defined by areas 73 and 8% is shown empty, whereas at '7B conductor strip 56 and pin 24 are illustrated as they would appear before the outer end of said strip is folded downwardly over bushing 99 as at 56C.

From the foregoing, it will be noted that those portions of the terminal ends of conductor pins 24 which project from the outer face 19 of end wall 18 of the terminal body are housed within the resilient insulator 38 whereby damage to the glass-to-metal seal by reason of the transmission of shock and/ or vibration to the seal via the free outer ends of the terminal pins is materially reduced, if not completely eliminated.

It will likewise be noted that the outer ends of the terminal pins are received within their respective grooves do in the terminal block 76 in such a manner that no bending force is transmitted to said pins incident to the bending of the connector strips 56 relative to their re spective conductor pins, incident to establishing an el ctrical connection as illustrated in FIG. 7. it will likewise be noted that the relationship of the resilient. insulator serves to effectively minimize the transmission of any shock loads to the terminal per se.

When the outer portions of the conductor strips are bent outwardly and over into channels 82 of the connector block, no bending force will be transmitted to the conductor pin with which the particular strips are associated, since the zone or locus of bend is disposed outwardly beyond the end of the pins.

Bending of the conductor strips as aforesaid will impart an outward axial force to the pins which will effecspending portions of the outer surface of base 46 of the resilient insulator bushing 37, as illustrated in FIG. 7.

The relationship between the connector block and the conductor pins of the terminal are such as to establish an elficient electrical connection between the outer terminal ends of said pins and associated portions of the connector block; and to provide a highly efiicient screw type connection by which conductorsmay be securely though releasably associated with said terminal via said block.

It should be understood that various changes and modifications may be made in the structural details of the device, within the scope of the appended claims, without departing from the spirit of the invention.
