This application is a continuation-in-part of U.S. patent application Ser. No. 716,075 filed Mar. 26, 1985, and a continuation-in-part of U.S. patent application Ser. No. 746,919, filed June 20, 1985, entitled "Electrical Connector For a Twin Axial Cable" both now abandoned. The invention relates to the field of electrical connectors, and is directed to an electrical connector for a twin axial electrical cable in which a pair of insulated conductors are contained in a conductive sheath of metal braid and an outer jacket of insulation material.
An electrical contact (26) for joining a ground wire (5) of a coaxial cable (1) to an electrical connector comprises, a first ring (27) assembled concentrically over a coaxial cable (1), a conductive second ring (28) assembled over the first ring (27) and clamped against a ground wire (5) of the cable (1), and the second ring (28) being joined conductively to a conductive ground contact (10) of the connector.
A system is provided for automatically switching an electric circuit on and off at certain times of the day, in which those certain times of the day vary throughout the year in accordance with a pattern built into the system and are not intended to be altered by the user. A computer timer provides the time of day and day of the year. A memory is permanently programmed with data that are stored to identify switch-on times and switch-off times for each day. The time of day and day of the year are compared with the switch-on times and switch-off times that are stored in the memory, and a current switching device is operated accordingly to switch an appliance, such as an electric lamp, on and off at the programmed switch-on times and switch-off times, respectively.
There is disclosed a coaxial contact for termination to a coaxial cable. The coaxial contact has an electrically conductive shell defining an open forward end (116). A center contact (56) for termination to a center conductor (208) of the cable is disposed concentrically within and isolated from shell (104) by a dielectric insert (26) and ferrule (28). A sleeve (300) is positioned over the cable jacket during assembly and after the center contact, dielectric insert and ferrule are positioned, the sleeve is employed to lay the braid strands over the ferrule. The sleeve may be left over the braid and crimped between the shell and braid.
A triaxial electrical connecter for terminating a triaxial electrical cable. The connector (10) is manufactured to comprise five major components including a center contact (21), intermediate and outer shell subassemblies (22,23), an intermediate ferrule (24) and a bushing (26), which can be easily assembled and attached to the end of a triaxial cable (12). The center contact (21) and the intermediate and outer shell subassemblies (22,23) include captivation structure for automatically aligning the components with respect to one another during the assembly process. The intermediate and outer shell subassemblies (22,23) include intermediate and outer contacts (41,71) and intermediate and outer insulating members (42,72) which are adapted to be press-fit into their respective contacts (41,71) for easy preassembly of the subassemblies (22,23) without specialized tools.
Inner and outer coaxial contacts (40, 50) of a connector are connected to first and second conductors (30, 32) of a cable by first crimping the conductors to the rear ends (90, 92) of a pair of terminals (84, 86) that have pin-shaped front ends (80, 82). Then, the pin-shaped front ends of the terminals are inserted into passages (74, 76) at the rear ends of the contacts to lie in a sliding fit with the contacts. The passage at the rear end of each contact holds a clip (100, 102) forming tines (104, 106) that grasp the pin at the front of a terminal to establish good electrical contact. An insulative terminal positioner (110) has bores (112, 114) that receive the terminals to position them. The rear portion (72) of the outer contact has two laterally spaced holes (140, 76) with centers lying on opposite sides of the connector axis, a second of the holes being the second connector passage (76) that receives the second terminal pin, and the first hole receiving the rear portion of the inner contact and the inner insulator.
