Abstract
Abstract An electrical connector for a multi-pin circuit module in which the circuit module (6) is supported on a carrier (7) slidably mounted on a base unit (2) with its connection pins (10) extending through holes (9) in the carrier (7). Sliding the carrier (7) causes the pins (10) to engage contact elements (4) on the base unit (2) and the arrangement is such that each pin (10) is supported by the carrier (7) in the region of engagement.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
192 words
An electrical connector for a multi-pin circuit module having an array of connection pins extending from one face including: a carrier plate of insulating material having a plurality of ridges on one surface, the ridges having a width between opposite edges which is less than the diameter of the connection pins, the carrier plate also having a plurality of holes corresponding one with each of the connection pins and extending through the plate and the ridges so that when the circuit module is supported on the carrier plate the connection pins extend through the holes with portions exposed at the opposite edges of the ridges; an insulating base member carrying a plurality of contact elements corresponding one with each of the connection pins and having inwardly facing turned over portions for engaging the contact pins therebetween; means for slidably mounting the carrier plate on the insulating base member so that the ridges extend between the turned over portions of the contact elements; and means operable to cause the carrier plate to slide so that the said exposed portions of the connection pins engage the turned over portions of their corresponding contact elements.
Claim 2
Dependent Claim
192 words

Claim 3
Dependent Claim
28 words
An electrical connector as claimed in claim 1, in which the contact elements are substantially U-shaped and are arranged to grip the connection pins with a predetermined pressure.
Claim 4
Dependent Claim
23 words
An electrical connector as claimed in claim 1, in which said means operable to cause the carrier plate to slide includes a cam.
Claim 5
Dependent Claim
30 words
An electrical connector as claimed in claim 1 in which the means for slidably mounting the carrier plate is provided by the ridges engaging complementary recesses in the base member.
