PLUG-CONNECTOR.

To atl whom it may concern:

Be it known that I, WILLIAM R. GREEN- wAY., a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Plug- Connectors, of which the following is a specification.

The invention relates tol electrical coupling devices, and more particularly to a plug connector having'one or more contacts.

It has for its object aplug connector in which the inclosingy casing or shell is readily separable andthe insulating blocks held by the same readily removable; to so secure these blocks to their respective shells that no screws or the like pass through the same into the inclosing casing; and to provide means to positively determine the polarity of the contacts where a plurality of con-- tacts are made by means of the connector.

A further object of the invention is to relieve the conductors, connected to the blocks, of strain in withdrawing the plug.

The nature of the invention will be best understood when described in connection with the accompanying drawings, in which- Fig'ure 1 is a plan of the connector. Fig. 2 is a plan of the connector with the upper shells removed. Fig. 3 is a section taken on the line 3-3, Fig. 2. Fig. 4 is an elevation, and Fig. 5 a plan illustrating a modification in the connector. Fig. 6 is an end view of the cover employed in connection with the modification illustrated in Figs. l and 5.

Similar characters of reference designate corresponding yparts throughout the several views. y

Referring now to the drawings, 10 and 11 designate respectively upper and lower shells forming the inclosing casing of the plug member of the connector; and 12 and 13 respectively the upper and lower shells, similarly forming the inclo-sing casing for the ,socket member of the connector. The shells are adapted to be secured to each other inany well-known manner, for example by means of screws, as shown. held between the

said shells

12 and 13, is a block of insulating material 14 provided on each side with a vertical groove 15 adapted to fit corresponding lugs 16 extending inwardly from the sides of the shells. A block 17 K of insulation is similarly held be- VVithin, and' tween the

shells

10 and 11 through vertical grooves 18 and lugs 19, the said block, however, extending beyond the end of the said shells. The part thus extending is adapted to lit a socket 20 at the end of the

shells

12 and 13. blocks of insulation andl the corresponding lugs extending inwardly from the shells, the said blocks are located and held against movement in their own plane, but may be readily removed by lifting the same. No other means to secure the blocks are required; and if, it be desired to tix the socket member as a whole, this may be readily effected by providing one of its shells, for example the shell 12, with suitable bosses 23 through which screws or bolts may pass. The inner ends of the shells forming the corresponding casingsof the plug and socket member are provided' with abutting

flanges

21 and 22 to determine the extent of the insertion of the plug block 17 into the socket 20.

As shown in Figs. 4, 5 and 6 a suitable spring pressed latch in the form of a cover may be pivoted to the shell 12 and engage a lug 25 on the shell 10 to prevent accidental separation of the members where considerable vibration is present. When the plug member is withdrawn from the socket 20, the cover 24 under the action of its spring 26 will drop down to close the said socket 20 and insure against accidental contact with the live terminals therein. The socket member may, furthermore, be connected to a support 27 in such a manner as to be capable of turning. This is accomplished' by means of the bolt 28 whose head`29 is locked in a boss `30 of the shell 12, said bolt passing through a bracket 30 secured to the support 27.

The plug may be provided` with one or more contacts to which suitable cables 31 and' 32 are brought through the outer or neck portion 33 and' 34' of the plug and socket member. These neck portions are provided with

flaring outlets

35 and 36 respectively to reduce wear on cables, and are of an enlarged 'diameter fora portion of their length to rovide cavities f5? and 38 respectively. A out the portions et the cables passing through these cavlt' able flexible materiai 39, sur-h as ins! tape, is wound about the said cab extent sufiicient to till' the whereupon when a strain is pnt on tr.. ,i

By means ofthe grooves in the` as in withdrawing a member, the same will be taken up to a largev extent by the said fiexible material and not be communicated to the terminal connections. These connections may be made by sweating the ends of the cable into suitable sleeves 40 adapted to fit within hollow terminal pieces 42 mounted within the

insulating blocks

14 and 17, and are positively secured thereto by means of set screws 41 passing through a portion of the insulating material and into the hollow meta-l terminals 42. From the outer end ot block 14 extend split contact plugs 43, and within the block 17 are provided suitable receptacles 44 to receive the said plugs. To insure the polarity of the connection, the block 17 is provided with a suitable groove 45 in its upper surface, said groove being adapted to it a lug 46 extending downwardly from the shell 12 of the socket member.
