Definitions

  • This invention relates to electrical connectors, and more particularly, to contact retaining means for connector assemblies.
  • a feature of this invention is a retention spring having a single spring tab or linger and which is adapted to tilt or cant on its associated contact both during insertion of said contact, and when the contact is subject to an axial pull, either with or without concurrent rotation.
  • FIG. 1A is a View in elevation of a contact having a contact spring and a retention spring in accordance with the principles of this invention
  • FIG. lB is an end view of the contact of FIG. 1A;
  • FIG. 2A is a view in elevation of the retention spring of FIG. lA;
  • FIG. 2B is an end View of the retention spring of FIG. 2A;
  • FIG. 3A is a view in elevation of the contact spring of FIG. 1A.
  • FIG. 3B is an end view of the contact spring of FIG. 3A.
  • reference character 1 indicates generally a female or socket type contact having at one end a central bore 2 adapted to vreceive the projection of a male or pin type contact, and at its other end a central bore 3 adapted to receive a conductor.
  • a peep hole 4 is provided to permit inspection of the extent of the insertion of the conductor into the bore.
  • the contact also includes a ridge 5, a neck portion 6 having a window 7 onto bore Z and a neck portion 8.
  • Disposed on neck portion 6 is a substantially C-shaped spring 9 having central dimple 10.
  • Dimple 10 projects through window 7 into bore 2.
  • neck portion 8 is a retention spring 11 having a single upstanding tab 12.
  • FIGS. 2A and 2B illustrate the retention spring 11, which is substantially of C shape. As shown in FIG. 2A, the upstanding center portion or tab 12 of the retention spring 11 is not parallel to the central axis of the spring.
  • FIGS. 3A and 3B illustrate the contact spring 9, which 3,031,638 Patented Apr. 24, 1962 V Y 2 is substantially of C shape.
  • the center portion of the C includes an inward-going surface 10a and a transition surface 10b. An inward-going dimple at the center of the C might also be used.
  • the contact spring 9 is snapped into neck portion 6 so that inwardgoing surface 10a projects through window 7 into bore 2.
  • Surface 10a will thus press the pin contact against the socket wall when the pin is inserted into bore 2, and ensure good mechanical and electrical contact between the pin and socket contacts.
  • Transition surface 10b is adapted to guide the inserted pin under the inward-going surface 10a.
  • Spring detent 11 is snapped onto neck portion 8. It will be noted that the neck portion 8 is of greater length from shoulder 8a to 8b, than the included spring 11 from edges 11a to 11b, and so spring 11 is adapted to cant on the neck 8 until its edges 11a and 11b contact shoulders 8a and -Sb respectively.
  • a conductor (not shown) is inserted into b ore 3 and secured therein by suitable means, suchas crimping. f
  • tab tip 12a abuts the shoulder 15 of the mounting panel and the spring 11 is rocked back into place, swinging tab tip 12a even' further above the hole. If the stress is increased the tab tip v12a will expand in the hole 13a increasing its locking power and removing any set induced by its insertion through hole 13.
  • the contact is now held in hole 13 by ridge 5 and tab tip 12a. If the contact is twisted, the contact will rotate within both the hole 13 and spring 11. There is no tend-v ency for the tab to be cammed back into hole 13 or to chew up the hole.
  • an extraction tool is inserted into hole 13a to depress tab 12a, permitting the convenient withdrawal of the contact from hole 13.
  • FIG. 1 illustrates a femal type contact
  • a male type contact may be similarly mounted.
  • a connector assembly comprising a dielectric housing, said housing including a mounting hole having a constriction of a given diameter; ametal contact having a contact-insert-portion, of less than said given diameter for insertion through said mounting-hole-constriction; said contactdnsert-portion including two shoulders and a section of reduced diameter therebetween; a retention spring disposed substantially coaxallyabout said section ofreduced diameter between said shoulders, and having a length shorter than the distance'between said shoulders; a portion of said retention spring normally projecting above the surface of said contact-insert-portion; the arrangement being such that upon said contact-insert-portion and said retention spring being inserted into said mounting hole said retention spring and said mounting hole constriction having a mode of operation wherein the inner surface of said constriction both depresses said retentionspring-projecting-portion and tilts said retention spring on said reduced-diametersection away from Aits coaxial relationship with said'reduceddiameter-section, said retentionspring-projecting
  • a connector assembly according to claim l further including:v a portion on said contact having a diameter of greater than said gi'ven size for preventing overinsertion v of said contact-insert-portion; and wherein the full insertion of said contact-insert-portion disposes said retentionspring-projecting-portion axially beyond said mounting hole constriction, whereby said retention-spring-projectingportion in its returned-to-norrnal height prevents withdrawal of said contact-insert-portion from said mounting hole.
