Description

DETAILED DESCRIPTION OF THE INVENTION Encased, shielded and grounded connectors are often used in power or control circuit applications requiring a high degree of electrical and mechanical integrity.

The connector typically provides both mechanical and electrical coupling to electrically operated equipment or similar connectors for rapid disassembly purposes. Known connectors generally include a plurality of male terminals that are received in complementary female sockets of a matching connector. The terminals and sockets are generally surrounded by a metal casing that is mechanically and electrically attached to the cable's electrical shield, a ground wire.

The known connector utilizes a brazed connection between the terminal case and the ground wire or gold maple sheath of the cable.

The area between the mechanical attachment point of the connector to the cable and the metal casing surrounding the terminals is conventionally wrapped in a conductive material, such as copper or aluminum foil, which is connected to the ground wire. , and a metal casing surrounding the terminal. The individual conductors of the cable are first sheathed for structural rigidity and then wrapped in foil to ensure adequate shielding of the wires from external electrical disturbances.

In accordance with preferred constructional embodiments of the present invention, the sheathed, shielded, and grounded connector provides structural support for its terminals and includes a metal casing surrounding the ends of the goople and the terminals of the connector. Features a metal housing that provides grounding and shielding of the electrical core between. The housing is encased in a non-conductive sheath, such as PVC, nylon, fluoropolymer, Teflon, or the like. The metal housing provides significant structural integrity that facilitates attachment of the connector to electrically operated equipment or compatible connectors. The structural form of the metal housing accommodates different orientations of the crimp sleeve, thereby orienting the cable at one of different angles relative to the housing of the connector.

As shown in FIG. 1, the sheathed, shielded, and grounded connector 10 is made of an insulating material, such as PVA, nylon fluoropolymer, etc., with an end 14 surrounding and supporting a multiconductor cable 16. It has a sheath 12. connector 10
The opposite end 18 of the connector 1017 is attached to the pin 20.2 to facilitate attachment to an electrically energized device or a complementary connector (not shown).
2.

As clearly shown in FIG. 2, according to the invention, the connector 1
0 comprises an inner housing 30 of metal, carrying for example a metal impression molding. The housing 30 has a converging portion 32, 34 at one end of the sled, terminating in a transverse portion 36. The transverse portion 36 has a hole 38 for receiving a crimping sleeve 40 . Sleeve 40 has a bent end flange 42 that extends through hole 38 and is mechanically secured around hole 38 . The flange 42 is secured within the bore 38 in a manner that provides a mechanically rigid connection as well as an electrical connection between the crimp sleeve 40 and the housing 30.

Note that the cable 16 has an insulating outer sheath 50 and a braided metal sheath 52. ·of. Sheath 52 acts as a protective envelope, ground connector, and electrical shield. Scabbard 5
2, the outer sheath 50 of the cable 16 is folded over a metal sleeve 53 with an inner diameter of Q. The woven metal sheath 52 and sleeve 53 are connected to the clasp 54 of the sleeve 40.
．． The sleeve 40 is crimped to the housing 30 at 56.
Provide mechanical and electrical connections between them.

The housing 30 includes a laterally outwardly extending flange 60.62 at the end opposite the sleeve 400 to accommodate the fixing pin 20.22. In addition to providing attachment to an electrical device or complementary connector, the bin 20.
22 connects a pair of laterally extending 7 langes 64.66 of the metal terminal envelope 68 to the housing 3007 langes 60.62.
Fix to. Thus, overall electrical continuity and shielding is provided by the housing 30 associated with the terminal envelope 68. A pair of metal sleeves 70, 72 having internally threaded holes 74 for accommodating the pins 20, 22 are attached to the housing 30.
7 langes 60, 62 and then molded into the outer sheath 12 as described below.

After the sleeve 40 of the housing 30 has been crimped onto the cable 16, the entire assembly including the bottle sleeve 70, 72 is placed in a mold and the insulating sheath 12 is molded onto the assembly surround 9. . In this way, a structurally integrated assembly with a high degree of electrical and mechanical integrity is obtained.

As clearly shown in FIG. 3, a crimp sleeve 40 extends from the convergent wall 34 of the housing 30. Both mechanical and electrical continuity are provided by the housing of the above-described embodiment. However, wall 34 and sleeve 400
The direction of the angle is the cable 16 for the how song 30.
gives the directionality of the angle. In this manner, a single housing stamp molding 30 is formed on the lateral end wall 3 as shown in FIG.
By providing the holes 38 of the sleeve 40 in either one of the angularly related walls 32 or 340 as shown in FIG.

Although preferred embodiments of the invention have been disclosed, the invention may be readily modified without departing from the scope of the claims.
