Abstract
Abstract A latching device is disclosed herein for releasably securing the components of a plugable electrical connector together to prevent inadvertent decoupling therebetween. The device includes a semicircular base attached to a support about one component of plugable connector while pivotally mounting a latch arm at one end. The opposite end of the latch arm is provided with a closure opening for cooperating with a closure latch projecting from the underside of a lug carried on the base in fixed spaced apart relationship with respect to the latch arm pivot connection with the base. When latched, the arm bears against the other component of the plugable connector so that the other component is fixedly held in connection with the first mentioned component of the connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
An electrical connector securing device for preventing unwanted disconnection of a socket from a plug in a socket and plug electrical combination comprising: an electrical plug; an electrical socket for insertably receiving said plug; a support yoke secured about said socket and having a pair of arms separated by said socket, each arm terminating in a yoke arm flange projecting outwardly normal to said yoke; a lever arm having opposite ends and pivotally secured at one end to a selected one of said yoke arm flanges and a latch means carried on one of the said lever ends detachably engageable with the other one of said yoke arm flanges; and said lever arm having an arcuate midsection engageable with said plug when said latch means is engaged for forcibly urging said plug into said socket and for supporting said plug on said socket.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
40 words
The invention as defined in claim 1 wherein: said plug includes a raised boss on its exterior surface engageable with said lever arm midsection and cooperating with said latch means to effect closure between said lever arm and said yoke.
Claim 4
Dependent Claim
57 words
The invention as define in claim 2 wherein: said yoke lies in a vertical plane and said lever arm pivoting about a vertical axis between an open position out of latch engagement with the other one of said yoke arm flanges and a closed position in latching engagement with the other one of said yoke arm flanges.
Claim 5
Dependent Claim
31 words
The invention as defined in claim 3 wherein: said lever arm oppostie ends when engaged with said yoke arm flanges respectively bias said lever arm midsection into engagment with said plug.
Claim 6
Dependent Claim
40 words
The invention as defined in claim 4 wherein: said lever arm opposite ends reside under said yoke arm flanges whereby said midsection urges said opposite ends agianst said yoke arm flanges when said lever arm is in its closed position.
