(1) To remove a contact (pin or socket), that has a defect, from connector housing (1), pull on wire (2) that is fastened to the contact.(2) If the wire is not fastened to the pin contact, remove pin contact (3) from the connector housing with needle-nose pliers (4).(3) If the wire is not fastened to the socket contact, push the socket contact out of the connector housing with a blunt (not sharp) 3.0Ø (0.12"Ø) rod (5).(4) Remove the old pin or socket contact from the wire. Cut the end of wire (2) evenly and then strip (remove) 4-5 (0.15"-0.18") of insulation from the end of the wire with 6V3001 Tool.(5) Put the smaller "U" opening of new socket contact (6) in the smaller jaws of 6V3001 Tool (7) as shown, with the open side of the "U" toward the double-arc edge of the jaws.(6) Put the stripped end of wire (2) in position in the smaller "U" opening of socket contact (6). Be sure the stripped end of the wire is completely in the "U" opening.(7) Completely close the jaws of tool (7). Open the jaws and remove socket contact (6). The jaws must be completely closed to be sure of a correct crimp on the wire and contact as shown.(8) Put the larger "U" opening of the contact in position in the larger jaws of tool (7), with the opening of the "U" toward the double-arc edge of the jaws. Completely close the jaws of the tool. Open the jaws and remove the contact. The correct installation of socket contact (6) on a wire is shown. The end of the stripped wire should extend beyond the small crimp so it can be seen at (A). The larger crimp (B) should firmly hold the insulation. The repair of a pin contact is the same as the socket contact. All pins and sockets should be soldered using a resin core solder.Installation Of Contact Assemblies In Connector Housings
The installation of contacts in a connector housing is the same for all connector housings. Installation of a contact into a four contact connector housing is shown as a typical example.(1) To install a socket contact assembly in a connector housing, put the end of 6V3008 Contact Insertion Tool (1) into a lubricant (such as alcohol), as shown. Put tool (1) in position so that the tube end of the tool can be installed through the front end of the connector body. Be sure plunger (2) is extended past the end of the tube.(2) Install tool (1)
