Abstract
Abstract The invention is concerned with separable electric connection devices of the kind comprising two rigid supports fitting one inside the other, e.g. a printed circuit board and a connector therefor, one support carrying at least one primary contact member and the other carrying at least one resilient secondary contact member the free end of which is movable in a direction fixed relative to its support, and mechanical means for displacing one support relative to the other in the said direction after the supports have been fitted together, to make contact between the primary and secondary contact members. In the device of the invention the mechanical means is adapted to effect such a movement in the said direction followed by a supplementary movement in a direction perpendicular to the said direction which provides a self-cleaning action on the contacts.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
226 words
A separable electrical connection device comprising two rigid supports having guide surfaces enabling the supports to be introduced one inside the other and to be extracted one from the other, one of the supports carrying at least one primary contact member while the other carries at least one resilient secondary contact member one end of which is free for displacement substantially in a direction which is fixed in relation to its support and is adapted to co-operate with the or one of the primary contact members of the other support, and mechanical means for displacing one of the supports relative to the other parallel to the said direction while the other support is held fixed, after the supports have been introduced one inside the other, characterised in that the mechanical means are adapted to effect, after the supports have been introduced one within the other, a first movement of the support to be displaced, parallel to said direction and directed in the sense which effects engagement between active surfaces of the primary and secondary contact members, followed by a supplementary movement of the same support which has a component perpendicular to the said direction and which has the effect of self-cleaning of said active surfaces, the mechanical means being adapted to act in the reverse direction before the extraction of the supports one from the other.
Claim 2
Dependent Claim
226 words
A separable electrical connection device comprising two rigid supports having guide surfaces enabling the supports to be introduced one inside the other and to be extracted one from the other, one of the supports carrying at least one primary contact member while the other carries at least one resilient secondary contact member one end of which is free for displacement substantially in a direction which is fixed in relation to its support and is adapted to co-operate with the or one of the primary contact members of the other support, and mechanical means for displacing one of the supports relative to the other parallel to the said direction while the other support is held fixed, after the supports have been introduced one inside the other, characterised in that the mechanical means are adapted to effect, after the supports have been introduced one within the other, a first movement of the support to be displaced, parallel to said direction and directed in the sense which effects engagement between active surfaces of the primary and secondary contact members, followed by a supplementary movement of the same support which has a component perpendicular to the said direction and which has the effect of self-cleaning of said active surfaces, the mechanical means being adapted to act in the reverse direction before the extraction of the supports one from the other.
Claim 3
Dependent Claim
19 words
An electrical connection device as claimed in claim 1, in which the or each primary contact member is non-deformable.
Claim 4
Dependent Claim
45 words
An electrical connection device as claimed in claim 2, in which the non-deformable primary contact members consist of the conducting tracks of a printed circuit board which constitutes one of the supports, the mechanical means acting on the support carrying the resilient secondary contact members.
