the tapered shoulder I8. At this point it may be mentioned that spring 23 is snapped into the groove 2i after placement of nut l5 on the body, the spring thereafter serving to prevent removal of the nut from the body. End lilo of the bodir may .contain suitable indicia, such as the polarizing groove 22 for orientation of the coupling in accordance withv the positions of the terminal sockets.
The core l I may be formed of any suitable electrical insulation, such as a phenolic condensation product, and is shown to include the conventional assembly of a main cylindrical'section 23 having enlarged diameter end ange or head 24, and a back-up disc 25. The core assembly may contain any suitable number and arrangement of metallic electrical terminalsor pins 26, two being shown as typical. These terminal pins may be of the usual form comprising an enlarged diameter socket portion `2l contained Within a bore in the core section 23 and adapted to receive a conductor prong inserted through opening 28 into the socket 29. The opposite end of the pin extends through the back-up disc 24 and is formed with the usual soldering'socket 39 for attachment to the conductor wire. The terminal pins are retained within the core assembly by engagement of the disc 2d with the end of the larger diameter socket portion 21 of the pin. The invention is independent of the particular type of terminal pin to be used, the illustrated form being conventional and therefore selected for purposes of description,`
Normally the core assembly H is retained in what is referred to as the retracted position of Fig. 2, where the terminal ends are entirely containedV within the body.` Location of the vcore in this position is predetermined by engagement of the head 24 with the internal annular body shoulder 32. The core is releasably held against movement toward the-projected position of Fig. l, by engagement of the tapered face 33 of disc 25 with arcuate shoulders 34 of corresponding angul-arity formed on the inside of the body sections Illa and lllb. As best illustrated in Fig. 3, shoulders 34 disappear toward the mating edges of the body sections. As will appear, by virtue of the sectional characteristics of the body and the action of spring 20, shoulders 34 serve as detents releasably holding the core assembly in its retracted position.
The projected position of the core is predetermined by engagement of the angular disc face 33 with shoulders 35 formed inside the body sections at or near the end thereof. As shown v in Fig. 2, shoulders 35 preferably are of arcuate extent, disappearing toward the mating edges of the body sections similar to the detent shoulders 34. It will be understood however, that if desired, shoulders 35 "may be made continuously annular Within the body and at n size 'diminution,'should it be desired to prevent removal of the core assembly irom the body other than by dismantling the sections. Formation of the shoulders 35 as illustrated has the advantage of permitting thecore assembly to be thrust out of the end of 'thebody without dismantling its sections. The core is releasably maintained in projected position and against pressure tending to move it into the body, by engagement of surface 36 on the head 21 with annular ,body section shoulders 3l similar to the arcuate shoulders34. y
Any suitable means may be provided to prevent rotation of the core assembly within the body,
while permitting its axial movement therein. As illustrative, the core may be maintained in predetermined orientation with the body by a key 38 extending between shoulders 32 and 35 and received within registering ways 39 in the core head and disc.
In considering the operation of the connector, assume the body t0 be assembled with the core in the retracted position of Fig. 2. Exertion of end pressure on the core at 4G, by the finger or a tool, causes the body section to spread against the resistance oi spring 20, permitting the'core assembly to be thrust forward to the projected position of Fig. 1, openly exposing the terminal ends for soldering in the usual manner to conductor wires. The combined effects of such factors as the angularity of shoulders 31 and the tension of spring 20, may be adjusted to give the core adequate support against return movement during soldering operations, While avoiding the necessity for excessive pressure to return the core when soldering iscompleted. At
this point it may be mentioned that should it be'desired to remove the core completely from the body, as for replacement of core parts, continuedend pressure on the core after reaching the position of Fig. 1, will cause the bodysections to'again spread and permit the core to be projected out of the body.
After the terminal connections are made, the core assembly maybe returned to retracted position by exertion of pressure against the end at 4l, causing the body t0 spread and' shoulders 34 nally to close behind the core as it engages the stopshoulder 32. Again it may be observed thatthe combined effects of the spring tension and angularities of the core surface 33 and shoulders 34, may be adjusted to retain the core in position against the end thrust or polarizing pressure applied as the terminal sockets 21 are thrust Aagainst the conductorprongs.
From the foregoing it will be apparent that the core vassembly is almost instantly movable between its retracted and projected positions, and that notwithstanding the speed and facility withy which the .connector may be so manipulated, the core is securely held in both positions against accidental displacement under all normal circumstances. Except for such purposes as removal of the core, the connector remains entirely self-contained vand 'involves for its manipulation only the simple application oi end pressure against the core inthe manner described.
When iinally joined to the companion prong assembly to be thrust into the pin sockets 21, the sleeve nut i5 is threaded on the usual threaded pronghousing or shell, tightening the end of such housing or shell into engagement' with shoulder t2.A Thereafter the lbody sections Illa and lub are maintained ltightly engaged by the Wedge action of surfaces `l'l and I8 independently of the spring 2d. Thus for assembly purposes the body is capable of spring-resisted spreading, but after final ensasementwith theprong (assembly the body sections become rigidly held in engagement.
