Technical Field

The utility model relates to an electric connector technical field, concretely relates to binding post.

Background

The electric connector can also be a plug/socket, is a basic element for carrying out electric connection and signal transmission between devices, assemblies and systems, and is widely applied to various electric circuits, and the wiring terminal is used as a core component of the connector, which directly influences the reliability and the service life of the connector.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve one of the technical problem that exists among the prior art at least, provide a binding post, including the elasticity grid, the sleeve has been cup jointed respectively at the both ends of elasticity grid, be provided with bellied spacing ring inwards on the sleeve, the elasticity grid is located the region between two spacing rings, two the sleeve is close to or the terminal surface looks welded fastening of butt relatively.

As a further improvement of the scheme, the elastic grids gradually protrude from the middle parts of the two ends towards the axial lead direction of the sleeve.

As a further improvement of the above scheme, metal rings are further arranged at two ends of the elastic grating, and the outer walls of the metal rings are abutted against or pressed against the inner wall of the sleeve.

As a further improvement of the above solution, the metal ring is integrally formed with the elastic grid.

As a further improvement of the scheme, one end or two ends of the elastic grating are fixedly welded with the limiting ring.

As a further improvement of the above solution, the elastic grid is formed by winding a metal sheet.

Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments.

As shown in fig. 1 to 4, a connection terminal comprises an elastic grid 2 and two sleeves 1 respectively sleeved at two ends of the elastic grid 2, wherein the sleeves 1 are provided with inward-protruding limiting rings 5, the limiting rings 5 and the sleeves 1 can be integrally formed, the elastic grid 2 gradually protrudes from the two ends to the middle part towards the axis direction of the sleeves 1, and the other expression is that the elastic grid 2 is recessed towards the inside of the sleeves 1, during assembly, the two sleeves 1 are respectively sleeved into two ends of the elastic grid 2 from the two ends of the elastic grid 2 to the two ends of the elastic grid 2 and are abutted or pressed against the side ends of the limiting rings 5, and then the end surfaces of the two sleeves 1 relatively close to or abutted are welded and fixed, thereby realizing stable connection of the whole connection terminal, only one welding position is needed during assembly, the assembly is convenient, the welding process is reduced, and the welding mode of the outer wall surfaces at the two ends of the elastic grid 2 and the contact position of the inner wall surface of the sleeves 1 is, the operation is convenient, and the welding slag is prevented from falling into the elastic grating 2 to influence the production quality; during the contact pin inserted elasticity grid 2, elasticity grid 2 produced elastic deformation and produced the elastic restoring force towards the axle center with the crimping contact pin, ensured contact pin and binding post and stabilized contact to increase the frictional force between contact pin and the binding post, further guaranteed contact pin and binding post and stabilized contact.

As a further improvement of the above scheme, as shown in fig. 1 and 2, both ends of the elastic grid 2 are provided with metal rings 3, the metal rings 3 and the elastic grid 2 are integrally formed, the radial outer wall of the metal ring 3 is abutted against or electrically connected with the inner wall of the pressure welding sleeve 1, further, one end or both ends of the elastic grid 2 are welded and fixed with the limit ring 5, as shown in fig. 4, the contact position between the end surface of the metal ring 3 and the limit ring 5 is welded and fixed, and the purpose is to reduce the number of parts of the connection terminal, reduce the production cost, and avoid the problem that the elastic grid 2 shakes on the sleeve 1 because the length of the elastic grid 2 is smaller than the distance between the two limit rings 5.

As a further improvement of the above scheme, as shown in fig. 1 and 2, the elastic grid 2 is formed by winding a metal sheet, the metal sheet may be made of a conductive metal material such as copper, aluminum, a copper alloy, or an aluminum alloy, and the metal sheet is provided with a plurality of waist-shaped holes or rectangular holes, and further, after the metal sheet is wound, the two ends of the metal sheet are reversely twisted to increase the elastic restoring force of the elastic grid 2, and the reverse twisting angle may be 5 ° to 10 °.

Above, only the preferred embodiment of the present invention has been described, the present invention is not limited to the above embodiment, and the technical effects of the present invention can be achieved by the same means, which all belong to the protection scope of the present invention.
