Summary of the invention
The purpose of this utility model is to provide a kind of micro-wire spring socket, to solve the bigger problem of radial dimension in prior art center line spring hole.
For achieving the above object, the utility model adopts following technical scheme: a kind of micro-wire spring socket, comprise the line spring hole section of front end and the matrix of rear end, this line spring hole section comprises tubular sheath, wired spring silk is set in the endoporus of this tubular sheath, the front end of described tubular sheath endoporus is fitted with the front end with the centre bore that passes for contact pin, the front end of described matrix has projection, this projection is inserted into the rear end of tubular sheath endoporus, a termination of described line spring silk is fixed between the mating surface of described tubular sheath and described front end, and another termination of described line spring silk is fixed between the mating surface of described tubular sheath and described projection.
The endoporus front end of described sheath has the flared section of aperture greater than the rear end, and the corresponding termination of described line spring is crimped between the mating surface of described flared section and described front end.
Has transition taper hole section between the flared section of the endoporus of described sheath and the adjacent holes section.
The afterbody of described front end cooperates with the endoporus of described tubular sheath, and the outer peripheral face section adjacent with described afterbody is the enlarging conical surface forward on the described front end.
Stretch out outside the described tubular sheath endoporus termination that described line spring silk is crimped between the mating surface of described tubular sheath and described front end, and the part that described line spring silk stretches out the tubular sheath endoporus is provided with the flange of fitting with the conical surface flared section of described front end.
The outer peripheral face section adjacent with described projection is the enlarging conical surface backward on the described matrix.
Stretch out outside the described tubular sheath endoporus termination that described line spring silk is crimped between described tubular sheath and the described projection, and the part that described line spring silk stretches out the tubular sheath endoporus is provided with the flange of fitting with the conical surface flared section of described matrix.
The afterbody of described matrix is provided with bonding wire cup or printed board binding post or line ball tube.
Line spring silk of the present utility model is arranged in the endoporus of sheath, projection by front end and matrix is fixed the two ends of line spring silk, sheath is equivalent to interior cover of the prior art in the utility model, but the outside of sheath does not have protheca and back cover, radial dimension is less, in addition, the two ends of prior art center line spring silk has the flange of 180 degree, more increased the radial dimension in line spring hole, a termination of line spring silk of the present utility model is crimped between front end and the sheath, another termination is crimped between the projection and sheath of matrix, does not need to be provided with the flange of 180 degree, has further reduced the radial dimension in line spring hole.
Has conical surface section on the outer peripheral face of front end of the present utility model and matrix, the part that the tubular sheath endoporus is stretched out at line spring silk two ends is provided with respectively the flange of fitting with the conical surface flared section of front end and matrix, flange forms retaining with the end face of sheath and cooperates, and guarantees that further line spring silk can Device for elimination of axial-and radial-play.
