Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector and a rolled contact piece. Background Art

[0002] In the prior art, a connector usually uses a pressure plate and an insulator to cooperate to fix a contact piece, which is called a two-plate buckling structure. This makes the contact piece inside the connector itself need to have a machined straight surface and a step to meet the axial limit fixation of the contact piece in the insulator and the function of preventing the wire welding cup from deflecting.

[0003] However, for a rolled contact piece, due to the limitation of the progressive die process, the root cannot be cleared to maintain a sharp corner during the processing of the diameter change, resulting in an over-large fillet radius, an increased diameter change range of the contact piece, and the contact piece density cannot meet the use requirements. At the same time, the rolled contact piece itself cannot be processed to form a step, so that the wire welding cup cannot have the function of preventing deflection.

[0004] Therefore, how to improve the structures of the existing rolled contact piece and the corresponding connector so that they can still achieve axial anti-retreat and circumferential anti-deflection without the need to process steps under the progressive die process is an urgent problem to be solved in the field. Summary of the Utility Model

[0005] The technical object of the utility model is to provide a connector and a rolled contact piece, which can realize reliable axial positioning and axial and circumferential anti-deflection functions of the rolled contact piece during processing under the progressive die process without processing steps on the outer surface through the improvement of the outer surface structure of the rolled contact piece and the cooperative structure setting of the insulating module and the fixed pressure plate.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a rolled contact piece includes a contact piece body rolled from a conductive strip.

Elastic claws and barbs are arranged on the outer surface of the sheath. After the contact member body together with the sheath is inserted into the insulator assembly, the elastic claws are used for axially blocking and cooperating with the insulator assembly to realize the axial positioning of the contact member body and the sheath, and the barbs are used for interference-fitting with the inner wall surface of the insulator assembly to realize the circumferential anti-rotation and radial limit of the contact member body and the sheath.

[0012] Further, the number of the barbs is at least two, and at least two barbs are evenly distributed along the circumference of the sheath.

[0013] Further, the barbs are in a ramp-like structure extending obliquely outwards, and the barbs are obliquely arranged outwards towards the back in the direction in which the contact member body is inserted into the insulator assembly.

[0014] Further, the number of the elastic claws is at least two, and at least two elastic claws are evenly distributed along the circumference of the sheath.

[0015] Further, the elastic claws and barbs are arranged in sequence front and back along the direction in which the contact member body is inserted into the insulator assembly.

The insulator assembly is arranged inside the connector housing and includes an insulating module and a fixing pressing plate which are arranged in cooperation front and back. Through holes for the rolled contact member to pass through are formed in both the insulating module and the fixing pressing plate. A positioning convex ring extends forward at the front end of the fixing pressing plate, and the positioning convex ring is inserted into the through hole of the insulating module.

[0046] A connector includes a connector housing, an insulator assembly and a rolled contact member. The insulator assembly is arranged inside the connector housing and includes an insulating module 5 and a fixing pressing plate 6 which are arranged in cooperation with each other in the front and rear directions.

At the same time, the barbs on the rolled contact pierce the inner wall of the through hole in the fixed pressure plate, and the barbs adopt a circumferential array, which can effectively reduce the radial shaking of the rolled contact and play a role in preventing the rolled contact from deflecting.

[0055] Elastic claws 2 and barbs 3 are provided on the outer surface of the rolled contact that bulges outwards in the middle. After the rolled contact is inserted into the insulator assembly, the elastic claws 2 pass through the mounting holes of the insulating module 5, and the movable ends of the elastic claws 2 abut against the front end face of the positioning convex ring 7 to achieve axial positioning of the rolled contact. The barbs 3 penetrate into the inner wall surface of the mounting hole of the fixing pressure plate 6, achieving circumferential anti-rotation and radial limitation of the rolled contact.
