MULTIWIRE CONNECTOR Filed Oct. 18, 1945 Patented Oct. 25, 1949 UNITED STATES PATENT OFFICE MULTIWIRE CONNECTOR John H. Munsey, Englewood, N. J. Application October 18, 1945, Serial No. 623,009

s claims. (o1. 173-328) The object of my invention is to provide improvements in multi-wire connectors of the quick detachment type, in which a considerable number o line wires may be quickly and easily assembled and disassembled without disturbing the line wire connections with the separable members of the connectors.

A further object of my invention is to provide a multi-wire connector in which an accurate and extended electrical contact is ensured between the contact ends of two alined'wire sections, said sections being emciently protected at their contact point.

A further object is to produce a multi-wire connector of simple form and inexpensive construction.

A still further object is to provide multi-wire connectors which may be readily combined, for instance, with switch boxes so that when trouble occurs in a switch box, the box together with its adjacent members ofthe connectors on the inlet and outlet side of the switch box may be re- Y moved as a unit to be inspected and repaired, and

a new switch box and its connector members may be quickly and easily installed for reducing the loss of service maintenance to a minimum,

A practical embodiment of my invention is represented in the accompanying drawings in which Fig. l represents in side elevation, partly in section, two of my improved multi-wire connectors attached to the inlet and outlet cables and their interposed switch box;

Fig. 2 represents in longitudinal central section one of my connectors with its separable members assembled as in use;

Fig. 3 represents a similar section with the members disassembled and separated; and

Fig. 4 represents a contact face View of one of the connector members.

The multi-wire connector consists of two matching members A and B of insulating materials, said members comprising resilient contact discs I and 2 secured, as by an adhesive, to their respective non-resilient backing blocks 3 and 4.

Any desired number of alined holes 5 and 6 within the capacity of the connector, are formed through the discs I and 2 and backing blocks 3 and 4 of the matching members A and B. Pairs of alined pins 'I and 8 of conducting material, as, for instance, brass, have a sliding iit in their respective pairs of alined holes 5 and 6. The :dat

heads 9 and I0 of these pins when pressure is not` applied thereto normally project beyond and overlap the contact faces of the discs I and 2. The ends 0f these conducting pins 'I and 8 project beyond the outer faces of their respective blocks 3 and 4 in position to be secured, as by twisting and soldering to the conducting line wires II and I2.

The means which I have shown for removably assembling the two members A and B of the connector is a screw bolt I3 which passes freely through a central sleeve I4 in the member B into threaded engagement with anl alined sleeve I5 in the member A. It will be observed that as the bolt I3 is screwed home the two members A and B will be-drawn tightly together, thereby imbedding the heads 9 and Ill of each pair of alined pins 'I and 8 in their respective resilient discs I and 2 and also compressing the said discs sufficiently to ensure a water-tight contact between the two connector members,

The means which I have shown for ensuring the proper assembly of the two members of the connectorA with their pairs of pins 1 and 8 in alinement and for ensuring the movement of the members in a right line with respect to each other, comprises lugs I6 and II projecting respectively from the blocks 3 and 4 through the discs I and 2 into their matching sockets I8 and I9 inthe blocks 3 and II respectively.

. These connectors are well adapted for use in systems where the connectors may be located between a switch box 2Iland their respective inlet and outlet cables A2l and 22. In this use of the connectors the members A may be inserted through openings 23 in the sides of the box 20 and secured iirmly therein as by providing the blocks 3 with peripheral flanges 2li to which flanges annular plates 25 of .metal'may be secured, as by glue. Screws 26 may be used to secure these annular plates 25 to the side walls of the box 20 around the openings 23.

When the connectors are used in connection with a switch box, if trouble arises in the switch box the members A may be released from the members B of the two connectors by unscrewing the bolts I3. The switch box 2B and its attached members A may then be removed as a unit and the trouble Alocated and eliminated. In the meantime another switch box with its attached connector members A may be substituted as a unit for the removed box and its connector members and the substituted members A secured to their respective connector members B, thereby reducing the loss in service maintenance to a minimum.

It will be seen that the two members A and B of the lconnector are caused to move in a right line with respect to each other as they are assembled and disassembled, thereby eliminating rotative movement of one member with respect to the other member. This right line movement,

-caused by the sliding engagement of the lugs I6v and I1 with their sockets I8 and I9 permits the heads 9 and I0 of the connector pins 'I and 8 to be initially located beyond the contact faces of the resilient discs I and 2, and imbedded in said 3 discs as the members are drawn into snug contact with each other. Furthermore it will be seen that by providing the pins with flat heads an extended contact is ensured between the two alined pins when the members A and B o the connector are assembled.

It is evident that various changes may be resorted to in the constructiony form and arrangement of the several parts without departing from the spirit and scope of my invenion, and hence I do not intend to be limited to the particular embodiment herein shown and described, but what I claim is:

1. In a multi-wire connector, two separable members having alined central bores, each member comprising a backing block of non-resilient insulating material and a contact disc of resilient insulating material permanently secured to the inner face of the backing block, pairs of coacting alined conducting pins slidable in their respective backing blocks and contact discs and having their contact ends provided with fiat heads nornormally projecting beyond and overlapping the contact faces o said discs, and a screw bolt slidable in the bore of one member and threaded into the bore of the backing block o1 the other member for drawing the members together in a right line, to imbed the contact ends of the alined pins in said discs and compress the discs for ensuring a water-tight contact between the two members.

2. In a multi-wire connector, two separable members having alined central sleeves, each member comprising a backing block oi nonresilient insulating material and a contact disc of resilient insulating material permanently secured to the inner face of the backing block, pairs or coacting alined conducting' pins slidable in their respective backing blocks and contact discs and having their contact ends provided with iat heads normally projecting beyond and overlapping the contact faces of said discs and a screw bolt slidable in the sleeve of one member and threaded into the sleeve of the other member for drawing the members together in a right line to imbed the Contact ends oi the alined pins in said discs and compress the discs to ensure a water-tight contact between the two members.
