Abstract
Abstract A contact pin and bushing assembly has the contact pin and a pin support, which limits the degree of insertion of the contact pin into an aperture in a circuit board, formed as separate items which are clamped together by the back end of the pin being pressed into a bore in the support. The pin support is provided at the base of the contact bushing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
A contact pin and bushing assembly comprising a contact pin having two approximately parallel legs for insertion into an aperture in a circuit board, which legs define an elongated hole therebetween and have a spring action one relative to the other, a support part having a shoulder for limiting the depth of insertion of the pin into said aperture, a contact spring bushing including a plurality of contact springs spaced from a longitudinal bushing axis and extending lengthwise from said support part to adjacent a plug pin insertion hole at one end of the bushing remote from the contact pin, wherein the contact pin is a stamped part independent of the support part and is connected to the support part by a clamped connection.
Claim 2
Dependent Claim
124 words
A contact pin and bushing assembly comprising a contact pin having two approximately parallel legs for insertion into an aperture in a circuit board, which legs define an elongated hole therebetween and have a spring action one relative to the other, a support part having a shoulder for limiting the depth of insertion of the pin into said aperture, a contact spring bushing including a plurality of contact springs spaced from a longitudinal bushing axis and extending lengthwise from said support part to adjacent a plug pin insertion hole at one end of the bushing remote from the contact pin, wherein the contact pin is a stamped part independent of the support part and is connected to the support part by a clamped connection.
Claim 3
Dependent Claim
32 words
An assembly as defined in claim wherein the support part is provided with a clamping hole in which a back end of the contact pin is inserted to form the clamped connection.
Claim 4
Dependent Claim
38 words
An assembly as defined in claim 2, wherein the back end of the contact pin is rectangular in shape and the distance separating diametrically opposite edges thereof is adjusted to conform to the diameter of the clamping hole.
Claim 5
Dependent Claim
19 words
An assembly as defined in claim 3, wherein the back end of the contact pin is square in shape.
Claim 6
Dependent Claim
32 words
An assembly as defined in claim 3, wherein two opposing sides of the pin are provided with an arch which runs in the direction of the pin axis in approximately parallel fashion.
Claim 7
Dependent Claim
46 words
An assembly as defined in claim 2, wherein the back end of the contact pin has two clamping legs bordering an elongated clamping hole formed by stamping, the clamping legs being inserted into the clamping hole and having a spring action one relative to the other.
