Abstract

Abstract An electrical contact of the tulip type for receiving legs of an integrated circuit or similar component. The contact has a tubular body produced by cold forming and has two parallel walls of small thickness through which are punched two tabs of substantially rectangular shape. The tabs face each other and converge towards the bottom of the tubular body. The walls of small thickness are connected by walls of larger thickness. When mounted in an insulating block, the contacts are oriented with the thinner walls parallel to the longitudinal axis of the block, and the longer side of the legs of the component to be received in the block are similarly arranged.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 127 words
An electrical contact of the tulip type for supporting an integrated circuit or similar component and comprising a tubular body having a closed end forming a bottom, said bottom being connected to a terminal provided to electrically cooperate with a hole of a printed circuit board and an open end of which is provided to receive a leg of said component which cooperates with a spring providing the electrical contact, characterized in that the tubular body is obtained by cold forming and comprises two parallelly extending walls having a small thickness through which are punched two tabs of substantially rectangular shape extending to face one another and converging towards the bottom of the body, the walls of small thickness being connected by walls having a larger thickness.
Claim 2
Dependent Claim 127 words
An electrical contact of the tulip type for supporting an integrated circuit or similar component and comprising a tubular body having a closed end forming a bottom, said bottom being connected to a terminal provided to electrically cooperate with a hole of a printed circuit board and an open end of which is provided to receive a leg of said component which cooperates with a spring providing the electrical contact, characterized in that the tubular body is obtained by cold forming and comprises two parallelly extending walls having a small thickness through which are punched two tabs of substantially rectangular shape extending to face one another and converging towards the bottom of the body, the walls of small thickness being connected by walls having a larger thickness.
Claim 3
Dependent Claim 24 words
The electrical contact of claim 1, wherein the bottom of said tubular body has opposite surfaces of reduced thickness and formed as flat portions.
Claim 4
Dependent Claim 17 words
The electrical contact of claim 1, including beveled walls adjacent said open end of said tubular body.
Claim 5
Dependent Claim 20 words
The electrical contact of claim 1, wherein the walls from which said tabs are punched are provided with beveled surfaces.
Claim 6
Dependent Claim 53 words
The electrical contact of claim 1, characterized in that said body has substantially rectangular openings which result from punching out of said tabs, the longitudinal dimension of said openings along the length of said contact being less than the thickness of an insulating block in which said contact is adapted to be received.
Claim 7
Dependent Claim 173 words
A support for receiving an integrated circuit or similar component, said support comprising an insulating block having at least one row of tulip type contacts inserted therein in a longitudinal direction, each of said contacts comprising a tubular body prolonged by a terminal adapted to electrically cooperate with a hole in a printed circuit board, said body having an open end adapted to receive a leg of said component, characterized in that each of said tulip type contacts comprises two parallelly extending walls having a small thickness through which are punched two tabs of substantially rectangular shape extending to face one another and converging towards the bottom of said body, the walls of small thickness being connected by walls having a larger thickness, each of said contacts being oriented in said insulating block with its thinner walls parallel to the longitudinal axis of said insulating block, whereby said contacts are adapted to receive rectangular shaped legs of said component in a manner such that said legs also extend parallel to said longitudinal axis.
Claim 8
Dependent Claim 173 words
A support for receiving an integrated circuit or similar component, said support comprising an insulating block having at least one row of tulip type contacts inserted therein in a longitudinal direction, each of said contacts comprising a tubular body prolonged by a terminal adapted to electrically cooperate with a hole in a printed circuit board, said body having an open end adapted to receive a leg of said component, characterized in that each of said tulip type contacts comprises two parallelly extending walls having a small thickness through which are punched two tabs of substantially rectangular shape extending to face one another and converging towards the bottom of said body, the walls of small thickness being connected by walls having a larger thickness, each of said contacts being oriented in said insulating block with its thinner walls parallel to the longitudinal axis of said insulating block, whereby said contacts are adapted to receive rectangular shaped legs of said component in a manner such that said legs also extend parallel to said longitudinal axis.
Claim 9
Dependent Claim 53 words
The support of claim 6, wherein said body has substantially rectangular openings which result from punching out of said tabs, the longitudinal dimension of said openings along the length of said contacts being less than the thickness of said insulating block, whereby a tight seal between said contact and said block is achieved.
Claim 10
Dependent Claim 16 words
The support of claim 7, including beveled walls adjacent said open end of said tubular body.
Claim 11
Dependent Claim 19 words
The support of claim 8, wherein the walls from which said tabs are punched are provided with beveled surfaces.
Claim 12
Dependent Claim 23 words
The support of claim 9, wherein the bottom of said tubular body has opposite surfaces of reduced thickness and formed as flat portions.
