Excessive force can lead to incomplete crimping of the wire, resulting in poor internal conductivity. Therefore, a compact, single-pin crimping fixture is needed to ensure the quality of crimped connectors during production.

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0031] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0032] Refer to the attached Figure 1-4, a tooling fixture for compact connection harness crimping, comprising a parallel pliers head 1, a wire harness limit block 2 connected to the inner side of the parallel pliers head 1, a limit slot 3 being provided on the wire harness limit block 2, the size of the limit slot 3 matching the size of the compact connection harness connector 4 to be crimped, when the device is working, the parallel pliers head 1 is installed on the parallel pliers body, and the parallel pliers body adopts the existing technology, which will not be described here, and the parallel pliers body can ensure that the two parallel pliers heads 1 remain parallel, close and separated when pressed, and after the wire harness limit block 2 is connected to the parallel pliers head 1, the wire harness connector 4 to be crimped can be placed in the limit slot 3 on the side, and finally the crimping operation of the wire harness connector 4 can be completed by pressing the parallel pliers body.

[0033] A first threaded hole 5 is provided on at least one parallel surface of the parallel pliers 1, and a second threaded hole 6 is correspondingly provided on the wire harness limit block 2. In this embodiment, the first threaded hole 5 and the second threaded hole 6 can be connected by screws to complete the connection between the wire harness limit block 2 and the parallel pliers 1. It should be noted that only the more conventional threaded connection method is cited here. The connection between the wire harness limit block 2 and the parallel surface can also adopt common detachable connection methods such as snap connection, which all fall within the scope of protection of this application.

[0034] There is at least one first threaded hole 5 , and one first threaded hole 5 can meet the connection requirements and facilitate disassembly and assembly. Of course, it should be noted that in order to improve the stability of the connection, two or more first threaded holes 5 can also be set.

[0035] The wire harness limiting block 2 is made of aluminum alloy, which has a strong structure and low weight. It should be noted that the wire harness limiting block 2 can also be made of other materials.

[0036] The second threaded hole 6 contains thread locking glue to improve the connection stability between the wiring harness limit block 2 and the parallel clamp head 1 .

[0037] The transverse dimension of the limiting groove 3 corresponds to the transverse dimension of the wiring harness connector 4, ensuring that the wiring harness limiting block 2 in the limiting groove 3 does not move laterally, thereby improving the accuracy during crimping.

[0038] The vertical dimension of the limiting groove 3 corresponds to the vertical dimension of the wire harness connector 4 after crimping. After crimping, the wire harness limiting block 2 can be in a suitable position to ensure that the compact connection wire harness connector 4 is crimped normally.

[0039] The limiting grooves 3 are symmetrically arranged at both ends of the harness limiting block 2. Figure 3 , two wiring harness connectors 4 can be crimped at one time.

[0040] The inner side of the parallel clamp 1 is fixedly connected to the wire harness limiting block 2 , and the fixed connection can be welding or integrally formed, etc., to further improve the stability of the wire harness limiting block 2 .
