Description

A riveting four-point crimping fixture for connectors

technical field

The utility model relates to the technical field of riveting fixtures, in particular to a riveting four-point crimping fixture used for connectors.

Background technique

Connectors are divided into soldering type and crimping type according to the connection method. In the past, most of the connectors were welded. With the upgrading of electronic products, the miniaturization of connectors and the high reliability requirements, the crimping method of connectors has become more and more common and has gradually become the main connection method. Crimping refers to a process method in which crimping tools or equipment are used to plastically deform the core wire in the wire and the connector to be connected to form an integrated metal structure in a natural environment.

At present, the crimping form of connectors and wires is generally single-point crimping. Some connectors, such as SMA and QMA terminals, need to be crimped at 4 points. If single-point crimping is used, point-by-point crimping is required. During the process, it is necessary to manually rotate the connector and repeatedly fix the crimping. Manual operation will inevitably cause errors, which will lead to irregular crimping interfaces, the shape of the crimped product is not beautiful enough, and the pass rate of the product is low. Manual operation is inefficient. Therefore, there is a need for improvement.

Detailed ways

In order to make the above purpose, features and advantages of the present utility model more obvious and understandable, the specific implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings of the utility model are in simplified form and use inaccurate ratios, which are only used to facilitate and clearly illustrate the purpose of the utility model embodiment.

As shown in Figures 1 to 10, a riveting four-point crimping jig for connectors includes a jig bottom plate 1, a jig seat 2, a jig pressure plate 3, a jig top plate 4, and a limit block 5 ;

The jig seat 2 is arranged on the upper part of the jig bottom plate 1, and inside it is provided with a slider groove 21 with an upward opening, and its center is provided with a through hole 22 placed front and back; Set of sliders 23; springs are arranged between the sliders 23, the inner side of which is provided with a rivet placement part 24, and the outer side is provided with a slope part 25; the described rivet placement part is a groove body, and four Riveting pin block 26; a spring is provided between adjacent riveting pin blocks, and the direction of the knife edge is set facing the center of the through hole 22;

The jig pressing plate 3 is fixed above the jig base 2 by bolts, and a group of guide sliders 31 are provided at its lower part; the inner side of the guide slider 31 is provided with a guide sliding slope 32 corresponding to the inclined surface. The guide sliding slope 32 is in contact with the inclined surface 25; a return spring 33 is also provided between the fixture pressing plate 3 and the fixture seat 2, which is used for the fixture pressing plate 3, The reset of the fixture top plate 4;

The jig top plate 4 is arranged on the upper part of the jig pressing plate 3;
