  • the socket connector of this invention advantageously provides torsion spring forces acting on wassociated male member serving toincrease the electrical contact and retention forces in the connection.
  • the unique torsional forces are provided through the use of a plurality of beams twisted along a longitudinal extent of the socket member.
  • the beams are provided with internal mating surfaces which form tracking elements to apply positive twisting forces to the male contact member as the male member is inserted into the bore of the socket contact.
  • An advantage of the present invention is the use of twisted track members to retain a pin within a socket and to provide an aggressiveelectrical contact between the two members.
  • FIG. I is a perspective view showing a typical application of the connectors of the present invention.
  • FIG. 2 is a side elevation view of one embodiment of the connector of the invention shown prior to association with a male contact.

  • Module 10 includes a plurality of such socket members 14 arranged to be associated with male contact members-l6 in module 12.
  • Suitable conductor wires 18 are attached to both the socket and pin members l4 and 16, respectively.
  • FIGS. 2-6 clearly show one embodiment of contact socket 14.
  • Socket 14 includes a front sleeve or ferrule portion 22 and rear sleeve or ferrule portion 24 interconnected by a plurality of beam members 26.
  • FIG. 3 shows that the beams 26 are elongated, channel-like members, circumferentially spaced about the axis of the bore extending through the socket.
  • the ferrule portions 22 and 24 are shown as a polygon having four sides with the beams 26 essentially being extensions of the corners 30 and 32 of the respective front and rear sleeves.
  • the beams are angle members with inner surfaces formed from longitudinally extending flat surfaces intersecting at an apex 28.
  • the rear sleeve 24 is shown to be angularly twisted or rotated out of alignment with the front sleeve 22.
  • the beam members 26 are similarly twisted out of alignment with the corners 30 of the front sleeve.
  • the contact 14, rear portion 24 and beams 26 are in the twisted position shown in FIG. 2 prior to the insertion of a pin and when the pin 16 is inserted therethrough the beams as shown in FIG. 37 will be twisted in a clockwise direction to assume the position of FIG. 5.
  • the beams are biased toward their twisted position, they will exert a constant twisting or torsion force on the pin 16 through the positive engage ment of the apices 28 and associated inner surfaces of the beams 26 and the corners of the pin 16.
  • This torsion force applied to the pin serves to provide firm, aggressive electrical contact between the two contact members and further to provide a strong mechanical gripping force tending to retain the pin 16 in the socket.
  • FIG. 6 is another side view of the connector shown in FIG. 2 but taken along a plane disposed approximately 45 from the longitudinal plane of FIG. 2.
  • front and rear barrel portions 22 and 24 are similar in configuration but are not angularly aligned with each other.
  • the tab means 25 extending rearwardly from the rear barrel portion enables conductors 18 to be attached to the contact 14 in a conventional fashion.
  • the beam members 26 are circumferentially spaced from one another by apertures 35.
  • cantilever spring members 34 are provided to extend between at least a pair of beams 26 and are normally biased radially outwardly from the contact member 14.
  • the contact shown in FIGS. 2-6 is adapted to be inserted and locked in a block 38 or a module such as I in FIG. 1.
  • the block 38 may be provided with a cavity having front and rear portions 40 and 42, respectively.
  • the front cavity 40 has a cross-sectional configuration which is complementary to the polygonal crosssectional shape of the ferrules 22 and 24.
  • the contact 14 is inserted into the cavity from the left as shown in FIG.
  • FIGS. 7-10 describe a further embodiment of the invention incorporating the basic principles described above.
  • Socket contact 14a includes front and rear ferrule portions 22a and 24a interconnected by a torsion spring section, including a plurality of beams 26a.
  • the corners of the front and rear ferrules are aligned while the beams 26a are twisted out of alignment with the corners of each ferrule portion.
  • the internal surfaces of the beams again intersect at an apex 28a and act as tracking surfaces for the associated pin member 16a in a manner similar to that described above.
  • the cavity in the housing-38a is of a polygonal shape complementary to the cross-sectional configuration of the contact 14a, but the rear portion of the cavity is, of course, of a cross-sectional area large enough to allow the beams 26a to be twisted during insertion of the male contact member.
  • Contact member 140 is designed to be inserted from the front of the module or from the right of the cavity shown in FIG. 7.
  • Spring members 340 compress upon entering the cavity and spring back into locking engagement with a shoulder in the cavity. These spring members 34a are also retained in a longitudinal slot 44 thus stabilizing the contact within the cavity.
  • Lug members 36a serve to limit the insertion of the contact in the cavity, as well as providing a slightly flared aperture aiding in the insertion of the pin in the socket.
  • the beam sections 260 will be required to twist against their normal bias and return to the position of FIG. 7.
  • FIGS. and 11 represent the configuration of the contact when it is associated with a pin member. The beams 26a will exert a constant twisting force on such a pin.
  • FIGS. 12-14 Yet another embodiment of the invention shown in FIGS. 12-14 is adapted to be inserted from the rear of the module or housing.
  • Contact member 1412 is insertable from the left of the FIG. 12, first passing through a rear cavity 42b and retained in an operative position by flexible spring retaining members 34h.
  • Members 34h are retained in slots 44b in the front cavity 40b and abut the shoulder between the front and rear cavity.
  • Abutment lugs 36b limit the axial insertion of the contact member in the cavity and are seated in radially extending slots, as shown in FIG. 14, retaining members 341; and 36b serving to also prevent relative rotation of the contact within the cavity.
  • the contact itself includes front and rear ferrule portions 22b and 24b having a polygonal configuration and including comer portions 30!; and 32b.
  • the corner portions of the front and rear barrels are shown to be an gularly misaligned originally as shown clearly in FIGS. 12 and 13.
  • the ferrule portions are integrally attached to one another through the torsion spring section including a plurality of beamlike members 26b.

  • a female electrical contact member adapted to receive a corresponding male contact member, said female member including at least one ferrule portion having a polygonal bore therethrough, a plurality of beams extending longitudinally from the ferrule portion, each beam comprising a pair of intersecting surfaces forming an internal corner, the corners of the beams forming longitudinal extensions of corner sections of the polygonal bore, said corner section extensions being twisted at least partially along their length thus being angularly displaced from the respective corners of the ferrule portion, wherein the insertion of the corresponding male member through the ferrule and beams twists the beams into alignment with the corners of the bore and creates torsional stress on the male member substantially throughout the length of the contact of the male member with the twisted beams.
  • a contact member in accordance with claim 1 which includes a front and rear ferrule portion interconnected by the plurality of beams.
  • a contact member in accordance with claim 1 which includes cantilever spring members extending radially from the ferrule portion to retain the contact member in an appropriate cavity.
