6 Claims.
This invention relates to an electrical connection.
The invention has for an object to provide a novel and improved electrical connection having a metal casing and provision for grounding the casing in a novel and improved manner.
A further object of the invention is to provide a novel and improved electrical connection of the plug and receptacle type in which provision is made for grounding the metal casing of the connection in a novel, simple and economical manner.
A still further object of the invention is to provide a. novel and improved grounding member for use in an electrical connection of the plug and socket type for grounding the metal casing of the connection.
With these objects in view and such others as may hereinafter appear, the invention consists in the electrical connector, in the grounding member, and in the various structures, arrangements and combinations of parts hereinafter described and particularly defined in the claims at the end of this specification.
In the drawing illustrating the preferred embodiment of the invention, Fig. 1 is a vertical longitudinal section through a sufficient portion of an electrical connector embodying the invention to enable the same to be understood; Fig. 2 is a cross-sectional view on the line 2-2 of Fig. 1; Fig. 3 is a side elevation of the preferred form of grounding member; Fig. 4 is a rear view of the same; Fig. 5 is a detail in side elevation illustrating the preferred form of ground contact member; and Figs. 6 and '7, elevations of the opposite ends of the contact member shown in Fig. 5.
In general, the invention comprises an electrical connector of the plug and socket type, and particularly a multi-pole connector adapted for use in a multi-pole electrical system, such as a two, three, or four-wire system, and in commercial form the plug and receptacle members of the connector are each provided with a. metal casing within which the contact members of the connector are 'operatively supported within insulating members positioned within the metal casings. In order to ground the metal casings of the plug and receptacle members of the con- 50 nection, provision is made in the preferred embodiment of the present invention for clamping a metal grounding member between component parts of the metal casing of each member, and the grounding member may and preferably will have provision for electrical connection with the 1934, Serial No. 717,720
(on. 173 s32 round contact member, so that in the use of the electrical connection the ground lead may be secured to the grounding member and a ground connection made to the ground contact through the grounding member, and in this manner a positive, durable and eflicient ground connection may be made between the metal casing and the ground lead.
Referring now to the drawing, which as above stated illustrates the plug member and a portion of the receptacle member of a multi-pole plug and receptacle connector embodying the invention, l0, I2 represent metallic casings, herein shown as comprising tubular sleeves, having their outer ends threaded and upon which the usual form of end members, one of which is shown at M, are screwed. The end members H are each provided with a shoulder l6 which is utilized in accordance with the present invention for clamping a grounding member l8 between it and the end of the metallic sleeves l0, l2, upon which the particular end member is screwed. The sleeves to, I2 have insulating members 20, 22, operatively supported therein and the female contact members 2| are mounted in elongated holes 23 in the insulating member 20 while the male contact members 26 are mounted in similar holes 21 in the insulating member 22. As shown in Fig. 2 the contact members are made of different shape in section and are arranged to fit into different and correspondingly shaped sockets in their insulating mountings for the purpose of insuring the reception of the proper contact member in the proper socket and in predetermined relation to each other, so that when the members of the electrical connector are brought together the proper male contact will fit into the proper female contact.
One pair of the contact members 2|, 26 comprises the ground contact, and in order to ground the metallic casings l0, l2, provision is made for connecting the casings l0, I2 with the ground contact members 2|, 26, and, as above stated, a metal grounding member, preferably a ring I 8, is clamped between each shoulder l6 of each end member I4 and the end of the sleeves 12 or l0. respectively, of the plug or receptacle'member of the connector. As herein shown, the grounding member is provided with a. boss 30 having a socket 32 for the reception of the grounding lead, not shown, to permit the same to be soldered to the grounding member l8, and the boss 30 is shaped to fit within a socket 34 formed in the end of the ground contact member 26, so that during the assembly of the component parts of the plug or receptacle members of the connector, the grounding member I 8 is electrically connected through the boss 3i) with the ground contact member 26 within the insulator 22 and the member 26 is grounded through the usual lead received within the socket 32 and soldered to the grounding member It. The grounding member l8 itself is clamped between the component parts of the metal casing of either the plug or receptacle members of the connector, establishing an emcient connection between the metallic casing and the grounding member.
While the preferred embodiment of the invention has been herein illustrated and described, it is to be understood that the invention may be embodied in other forms within the scope of the following claims.
Having thus described the invention, what is claimed is:
1. An electrical connection comprising a metallic casing composed of a plurality of component members, an insulating member supported within the casing, a plurality of contact members mounted in the insulating member, one of which comprises a ground contact, a metallic grounding member clamped between component members of said casing to be electrically connected therewith and having provision for electrical connection to the ground contact to effect grounding of the casing.
2. In an electrical connection, a metallic casing comprising a plurality of component members, an insulating member supported within the casing, a plurality of contact members supported in the insulating member, one of which comprises a ground, a metallic grounding ring clamped between the component members of the metallic casing and provided with a boss adapted to fit into the ground contact to effectively ground the casing.
