Abstract
Abstract An electrical plug has locking hooks on the ends of flexible arms extending from its housing. An electrical socket has locking receivers on its housing. When the plug is connected with the socket, the locking hooks engage the locking receivers to form a locked connection. A spring-loaded unlocking bail is pivotally arranged on the housing of the socket. Finger pressure applied to the bail against the spring bias pivots the bail so that its bail legs pivot over and press against protrusions of the flexible arms, to inwardly deflect the arms and disengage the locking hooks from the locking receivers, thereby unlocking the arrangement so that the plug can be separated from the socket.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
243 words
A lockable electrical connection comprising first and second connectors that can be selectively connected and disconnected with respect to one another, wherein: said first connector includes a first housing, a first electrical contact in said first housing, and a deflectable locking member extending from said first housing; and said second connector includes a second housing, a second electrical contact in said second housing, a locking receiver provided on said second housing, an unlocking lever pivotally connected to said second housing to be pivotal between an inactive position and an active position, and a biasing spring arranged between said second housing and said unlocking lever to exert a biasing force on said unlocking lever to bias said unlocking lever toward said inactive position; wherein: said locking member and said locking receiver are adapted to engage with one another in a locked condition when said first connector and said second connector are connected together in a connected condition, so as to lock said connected condition; said first and second electrical contacts are brought into electrical contact with one another when said first and second connectors are connected together into said connected condition; and when said first and second connectors are in said connected condition, said unlocking lever can be pivoted to said active position in which said unlocking lever acts on and deflects said locking member out of engagement with said locking receiver so as to release said locked condition and unlock said connected condition.
Claim 2
Dependent Claim
243 words
A lockable electrical connection comprising first and second connectors that can be selectively connected and disconnected with respect to one another, wherein: said first connector includes a first housing, a first electrical contact in said first housing, and a deflectable locking member extending from said first housing; and said second connector includes a second housing, a second electrical contact in said second housing, a locking receiver provided on said second housing, an unlocking lever pivotally connected to said second housing to be pivotal between an inactive position and an active position, and a biasing spring arranged between said second housing and said unlocking lever to exert a biasing force on said unlocking lever to bias said unlocking lever toward said inactive position; wherein: said locking member and said locking receiver are adapted to engage with one another in a locked condition when said first connector and said second connector are connected together in a connected condition, so as to lock said connected condition; said first and second electrical contacts are brought into electrical contact with one another when said first and second connectors are connected together into said connected condition; and when said first and second connectors are in said connected condition, said unlocking lever can be pivoted to said active position in which said unlocking lever acts on and deflects said locking member out of engagement with said locking receiver so as to release said locked condition and unlock said connected condition.
Claim 3
Dependent Claim
25 words
The lockable electrical connection according to claim 1 , wherein said first connector is a connector plug and said second connector is a connector socket.
Claim 4
Dependent Claim
38 words
The lockable electrical connection according to claim 1 , wherein said biasing spring exerts said biasing force being greater than a total sum of counter-forces exerted on said unlocking lever by one or more of said locking members.
Claim 5
Dependent Claim
72 words
The lockable electrical connection according to claim 1 , wherein said biasing spring exerts said biasing force being less than a total sum of counter-forces exerted on said unlocking lever by one or more of said locking members, and wherein said locking receiver includes a counter-protrusion with a lateral protrusion height at least as large as, and directed contrary to, a lateral protrusion height of a locking hook of said locking member.
Claim 6
Dependent Claim
36 words
The lockable electrical connection according to claim 1 , wherein said pivot axis extends parallel to a junction plane defined by respective faces of said first and second connectors facing each other in said connected condition.
Claim 7
Dependent Claim
40 words
The lockable electrical connection according to claim 1 , wherein said unlocking lever is adapted to be pivoted from said inactive position to said active position by application of manual finger pressure to said unlocking lever against said biasing force.
Claim 8
Dependent Claim
106 words
The lockable electrical connection according to claim 1 , wherein: said locking member comprises a flexible arm extending from said first housing, a locking hook disposed at a free end of said flexible arm, and a protrusion protruding laterally from said flexible arm; said locking hook is adapted to engage with said locking receiver in said locked condition; and said protrusion and said unlocking lever are positioned so that said unlocking lever contacts and presses laterally on said protrusion to deflect said flexible arm and thereby move said locking hook out of engagement with said locking receiver when said unlocking lever is in said active position.
Claim 9
Dependent Claim
22 words
The lockable electrical connection according to claim 7 , wherein said unlocking lever in said inactive position does not contact said protrusion.
Claim 10
Dependent Claim
