Abstract
The utility model discloses an elastic piece structure of a connector. The elastic piece structure is shaped as an inverted 'U'; an elastic piece is installed in the side wall, with a screw hole, of a contact wiring hole; an elliptical hole is opened in a position, corresponding to the screw hole of the contact wiring hole, of an outer side wall of the elastic piece; an inner side wall of the elastic piece is placed in the contact wiring hole and is shaped as an 'S'-shaped cambered surface from top to bottom. The elastic piece can fit the contact wiring hole more closely so as to produce a pre-tightening force, the elastic piece is not easy to fall off even when a bolt is not installed, a wire can be prevented from being damaged by a screw, a protective function is achieved, and automatic assembly can be realized conveniently. Moreover, as the inner wall of the elastic piece is designed into a cambered surface, the elastic piece structure has better elasticity, wires of a larger range of sizes can be inserted, and the elastic piece structure can be used more widely.
Description
Technical field
The utility model relates to the technical field of connector, and is special relevant with the elastic piece structure of connector.
Background technology
Early stage connector elastic piece structure is to be the L type, and this shell fragment very easily comes off out from the contact wiring hole.For this reason, have the dealer to improved, develop U-shaped shell fragment, the blind end of U-shaped shell fragment is fastened on the sidewall of contact wiring pore area screw, the madial wall of U-shaped shell fragment places in the contact wiring hole, and the screwhole position of the corresponding contact wiring hole of the lateral wall of U-shaped shell fragment is offered elliptical aperture, and screw is set in the screw of the elliptical aperture of U-shaped shell fragment and contact wiring hole and locatees, U-shaped shell fragment is fixed on the contact wiring hole, replaces the early stage L type shell fragment that easily from the contact wiring hole, comes off thus.But this U-shaped shell fragment elasticity is unsatisfactory, and U-shaped shell fragment and contact wiring hole are fitted inadequately, do not have pretightning force, and before not having mounting screw, U-shaped shell fragment comes off easily, is not easy to the automation assembling.
The utility model content
The purpose of this utility model is to provide a kind of connector elastic piece structure, so that shell fragment is combined with the contact wiring hole is more firm, prevents that lead from being damaged by screw, shields.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of connector elastic piece structure, be the lower frame type, shell fragment is installed on the sidewall of contact wiring pore area screw, and the screwhole position of the corresponding contact wiring hole of the lateral wall of shell fragment is offered elliptical aperture, the madial wall of shell fragment places in the contact wiring hole, and the madial wall of shell fragment is S-type cambered surface from top to bottom.
The madial wall epimere of described shell fragment arches upward to contact wiring hole center, and hypomere arches upward and is pressed on the sidewall of contact wiring pore area screw to the sidewall of contact wiring pore area screw, and whole madial wall is the cambered surface of smooth transition from top to bottom.
The madial wall of described shell fragment is that forward and backward contact wiring hole center is stuck up and the form of middle side walls collapse to contact wiring pore area screw.
After adopting such scheme; the utility model is because make globoidal structure with the madial wall of shell fragment; make shell fragment to fit more with the contact wiring hole; produce pretightning force thus; also difficult drop-off of shell fragment before mounting screw not; can prevent that lead from being damaged by screw and shield, be convenient to realize the automation assembling.And, the madial wall of shell fragment is made globoidal structure, elasticity is better, can be fit to the more lead insertion of large scale scope, uses wider.
Below in conjunction with drawings and the specific embodiments the utility model is described in further details.

Label declaration
Madial wall 13
Contact wiring hole 2 screws 21 sidewalls 22
Screw 3
Lead 4.
Embodiment
As shown in Figures 1 to 4, be a preferred embodiment of the present utility model.
A kind of connector elastic piece structure is the lower frame type, and shell fragment 1 is installed on the sidewall 22 of contact wiring hole 2 band screws 21.Elliptical aperture 12 is offered in screw 21 positions of the lateral wall 11 corresponding contact wiring holes 2 of shell fragment 1, and the madial wall 13 of shell fragment 1 places in the contact wiring hole 2, and the madial wall of shell fragment 1 is S-type cambered surface from top to bottom.Madial wall 13 epimeres that specifically are shell fragment 1 arch upward to contact wiring hole 2 centers, hypomere arches upward to the sidewall 22 of contact wiring hole 2 band screws 21, the madial wall 13 of shell fragment 1 can be pressed on the sidewall 22 of contact wiring hole 2 band screws 21, whole madial wall 13 is the cambered surface of smooth transition from top to bottom, make shell fragment 1 to fit more with contact wiring hole 2, produce pretightning force thus, before mounting screw 3 not, shell fragment 1 is difficult drop-off also, is convenient to realize the automation assembling.And the elasticity of shell fragment 1 is better, can be fit to the more lead insertion of large scale scope, uses wider.
In addition, as Figure 1-1, the utility model also is madial wall 13 design of shell fragment 1 that forward and backward contact wiring hole 2 centers are stuck up and the form of middle sidewall 22 depressions to contact wiring hole 2 band screws 21.This structure more is conducive to the insertion of lead 4.
Being specific embodiment of the utility model only below, is not the restriction to protection range of the present utility model.All equivalent variations of doing according to the mentality of designing of this case all fall into the protection range of this case.
Claims (3)
