Definitions

  • electrical connectors such as, the pin and socket type
  • mounting means such as insulated housings made of dielectric or other plastic material
  • they are generally disposed in spaced parallel openings therein, which, when the housing containing pins is mated with the housing containing sockets, the pins are telescopically disposed within corresponding sockets to provide electrical and mechanical interconnect-ion.
  • Another objective is the provision of a cavity in a housing which will frictionally hold an electrical connector as well as allow the contact engaging end of the connector to move radially so as to meet a mating electrical connector if the mating connector is not concentric with the first connector.
  • Another object of the present invention is to provide a seat in a housing cavity in which a spring latch means of an electrical connector is seated.
  • a further object of the present invention is the provision of stabilizing electrical connectors in position in a housing for engagement with mating electrical connectors in another housing.
  • FIGURE 1 is a front elevational view of a connector housing constructed in accordance with the present invention
  • FIGURE 2 is a side elevational view of the housing of FIGURE 1 and partially in section along lines 2--2 of FIGURE 1 showing a socket contact being inserted into a cavity therein;
  • FIGURE 2a is an enlarged fragmentary view of a feature of FIGURE 2;
  • FIGURE 3 is a side elevational view similar to FIGURE 2, but showing the socket contact fully inserted;
  • FIGURE 4 is a side elevational view partially in section and showing a pin contact and housing which mates with the housing of FIGURES 1, 2 and 3;
  • FIGURE 5 is a partially sectioned view showing the contacts and housings mated.
  • the present housing H comprises a dielectric member, suitably molded or formed in any conventional manner.
  • Housing H has a series of spaced parallel cavities 2 formed therethrough to slidably receive contacting contacts or terminals S of the socket or receptacle type.
  • Each cavity 2 has a large opening 4 at its rearward end which receives contact S.
  • Hole 4' extends from opening 4 into the cavity and provides an enclosure for the wire barrel W of contact S when it is fully inserted into the cavity.
  • Hole 4' joins a smaller hole 6 near the center of the cavity wherein contact stabilizing members 8 on the contact are slidably received.
  • Stabilizing members 8 project outwardly from the periphcry of contact S and are preferably disposed equidistantly therearound.
  • a smaller tapered hole 10 which constitutes the contact-engaging means.
  • An annular ledge 6' is formed between holes 6 and 10 against which a stop member 22 on the contact abuts to limit inner movement of the contact within the cavity.
  • This hole 10 is tapered, as shown, so as to frictionally engage the outer surface of contact S when it is pushed into cavity 2.
  • the small end of tapered hole 10 terminates into a large opening 12 near the forward end of cavity 2.
  • Tapered hole 10 has an integral annular lip 14 which eX- tends into large opening 12. This portion of lip 14 which extends into opening 12 is undercut as designated at 16 so that lip 14 may spring ope-n slightly when contact S enters therein.
  • This arrangement provides a stabilizing means by which the protruding portion 20 of contact S will have a limited freedom of radial movement to compensate for minor misalignments between pin and socket contacts when the connector halves are brought together for engagement.
  • Opening 12 provides an enclosure into which protruding end 20 of contact S is disposed.
  • End 18 of lip 14 is squarely cut, as shown, so that a spring latch 15 on contact S, such as disclosed in US. patent application Ser. No. 319,020, filed Oct. 25, 1963, now abandoned, will snap outwardly therefrom when the contact is bottomed into cavity 2.
  • Spring latch 15 will abut end 18, or move under lip 14 depending upon the thickness of spring latch 15 or lip 14, when rearward pull is exerted on contact S.
  • the combination of stop member 22 on contact S abutting ledge 6' in one direction, and the spring latch operation as described above, will prevent the contact from becoming accidentally dislodged from cavity 2.
  • An electrical contact S is suitably crimped or coldforged to the conductor portion of wire C to provide a current coupling member for the connector.
  • This contact is inserted into a housing cavity as described hereinbefore.
  • a spring latch 15 on the contact which is biased downwardly, becomes depressed towards the body of the contact, as shown in FIGURE 2.
  • stop member 22 on the contact abuts ledge 6 between hole 6 and hole 10.
  • spring latch 15 snaps into place outwardly from lip 14 as shown in FIGURE 3. This arrangement limits longitudinal movement of contact S relative to housing H.
  • FIGURE 4 shows a pin contact P in place in a housing H.
  • This assembly constitutes the other half of the connector, and mates with the assembly of FIGURE 3.
  • This pin and housing are disclosed in said last mentioned US. patent application. It is to be understood that the contact engaging means, contact stabilizing means, and contact latching means disclosed hereinbefore may be utilized in its entirety or in part in t-he housing shown in FIGURE 4.
  • FIGURE 5 shows the herein disclosed connector and the connector of FIGURE 4 in engageable relationship by which a mechanical and electrical interconnection is made between the two connector halves, and the housings in which the connectors are mounted are also shown in mating relationship.
  • a dielectric housing having an opening extending therethrough, said opening provided with a tapered section, a resilient annular lip at one end of said tapered section and an abutment at the other end of said tapered section, said annular lip being spaced from a surface of said opening; an electrical contact having a body section provided with projection means engageable with said abutment to limit movement of said electrical contact in one direction in said opening and a spring latch means having a free end disposed between said annular lip and said surface of said opening to limit movement of said electrical contact in another direction in said opening, said annular lip engaging said body section of said electrical contact to permit freedom of movement of said electrical contact so as to become aligned with a complementary electrical contact during inter-engagement therebetween.
  • a dielectric housing having an opening extending therethrough, said opening having an engaging section of less diameter than said opening, said engaging section being provided with resilient lip means spaced inwardly from as urface of said opening and extending along said surface; an electrical contact disposed in said opening, said electrical contact having a body section provided with projection means and latch means, said body section and said projection means being disposed in engagement with said engaging section and said body section being in snug and resilient engagement with said resilient lip means, said latch means being in engagement wit-h said lip means between said surface and said lip means, said projection means being engageable with said engaging section and said latch means being engageable with said lip means thereby maintaining said electrical contact in position within said opening, said resilient lip means in resilient and snug engagement with said body section permitting freedom of movement of said electrical contact in said opening so as to align with a complementary electrical contact during interengagement therebetween.
  • a dielectric housing having an opening extending therethrough, said opening having an engaging section being provided with resilient lip means spaced inwardly from a surface of said opening and extending longitudinally of said surface; an electrical contact having a body section provided with positioning means and latch means, said body section being disposed in said engaging section; said positioning means and said latch means in association with said engaging section positioning said body section within said opening and said engaging section; said latch means having an end disposed between said lip means and said surface; said lip means providing for limited freedom of movement of said electrical contact in said opening so as to effect alignment with a complementary electrical contact during interengagement therebetween.
