Abstract
Abstract Lamp sockets are provided which may be inserted through an opening from a first side of a thin wall and twisted to lock in position against the other side of the wall. Locking is affected between orienting, or aligning, shoulders integral to the socket and openings in the thin wall. The sockets include electrical contact elements which complete connections with conductors formed by flexible circuits, printed circuits or the like, positioned along the face of the first side of the thin wall, thereby enabling electric circuits to be completed between the sockets and the conductors.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
An electric lamp socket for completing electrical connections to conductors supported on a thin wall, such as the wall of a lamp housing, comprising a socket body formed of insulating material, an insert formed of insulating material and shaped to fit into said socket body and latch therewith, means in said socket body supporting a first group of discrete electric contact elements for completing electric connections to the base of an electric bulb, when inserted in said socket, means in said socket body supporting a second group of discrete electric contact eleMents in electrical contact with respective elements of said first group of electric contact elements, said second group of discrete electric contact elements including spring elements arranged along an outer face of said socket body and adapted to contact external conductor elements, and means formed in said insert to engage said first and second groups of electric contact terminals to lock them in conductive engagement in the socket.
Claim 2
Dependent Claim
159 words
An electric lamp socket for completing electrical connections to conductors supported on a thin wall, such as the wall of a lamp housing, comprising a socket body formed of insulating material, an insert formed of insulating material and shaped to fit into said socket body and latch therewith, means in said socket body supporting a first group of discrete electric contact elements for completing electric connections to the base of an electric bulb, when inserted in said socket, means in said socket body supporting a second group of discrete electric contact eleMents in electrical contact with respective elements of said first group of electric contact elements, said second group of discrete electric contact elements including spring elements arranged along an outer face of said socket body and adapted to contact external conductor elements, and means formed in said insert to engage said first and second groups of electric contact terminals to lock them in conductive engagement in the socket.
Claim 3
Dependent Claim
41 words
The invention as claimed in claim 1, including latching means associated with said socket body to enable said socket body to be locked to a wall after a portion of said socket body has passed through a hole in said wall.
Claim 4
Dependent Claim
22 words
The invention as claimed in claim 2, in which said latching means includes a plurality of alignment shoulders integral to said socket.
Claim 5
Dependent Claim
40 words
The invention as claimed in claim 3, in which said latching means includes a flange integral to said socket against a face of which the entrance side of a wall impinges when the socket body is locked to the wall.
Claim 6
Dependent Claim
25 words
The invention as claimed in claim 1, in which the spring elements include tongue shaped portions supporting contact tips suitable to engage external conductor elements.
Claim 7
Dependent Claim
54 words
The invention as claimed in claim 5, in which the tongue shaped portions are aligned along arcs of a circle drawn around the central axis of the socket, said alignment providing for wiping motion of said contact tips against external conductor elements in a direction tangent to said circle when the socket is rotated.
Claim 8
Dependent Claim
38 words
The invention as claimed in claim 5, in which the contact tips are shaped like frustrums of cones having their large bases integral to the spring elements and having their small bases rounded to engage external conductor elements.
Claim 9
Dependent Claim
17 words
The invention as claimed in claim 5, in which the contact tips are substantially hemispherical in shape.
Claim 10
Dependent Claim
41 words
The invention as claimed in claim 1, in which the first group of contact elements include openings therethrough, and the second group of contact elements include extensions to mate with said openings and lock the contact elements together in said socket.
Claim 11
Dependent Claim
43 words
The invention as claimed in claim 1, including a pad fitting between said second group of contact elements and a portion of said socket to support said second group of contact elements and to provide a seal between said socket and a wall.
Claim 12
Dependent Claim
57 words
The invention as claimed in claim 1, in which a flange is provided integral to the socket body to serve as a stop when the socket body is inserted through an opening in a thin-walled housing, said flange including said outer face with spring elements arranged thereon to contact external conductor elements positioned on the thin-walled housing.
