[0002] Wire harness connectors are crucial components in automotive wiring harness assembly. However, incorrect orientation is common during assembly. This occurs when a worker holds the connector in one hand and inserts it into the wiring harness with the other; if the connector is misaligned, the wiring harness may be inserted incorrectly or improperly, leading to poor connections or damage. This error not only increases assembly time and costs but also reduces the reliability and safety of the wiring harness. Because incorrect connector orientation is difficult to identify visually, quality control becomes particularly challenging. Each connector needs to be carefully inspected, which not only increases workload but also increases the risk of missed inspections or misjudgments. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0024] See Figures 1-2 A connector positioning and clamping error-proof device includes a positioning fixture 1. The front of the positioning fixture 1 has a fixture cavity 2, and the end face of the fixture cavity 2 has a first chamfer 3 to facilitate connector insertion. The middle of the fixture cavity 2 has a guide post 4, and the end face of the guide post 4 has a pin hole 5 for accommodating the connector pins. When the connector is inserted into the fixture cavity 2, the connector pins will be inserted into the pin hole 5. Similarly, the end face of the pin hole 5 also has a chamfer. One inner wall of the fixture cavity 2 has a limiting boss that matches the positioning notch of the connector. 6. The guide post 4 is provided with a limiting protrusion 7 on the side away from the limiting boss 6, which is adapted to the positioning groove of the connector. The connector is limited by the limiting boss 6 and the limiting protrusion 7, which can not only ensure the accuracy of the direction, but also improve the stability of the connector installation. The front end face of the positioning fixture 1 is provided with a direction mark 8 to indicate the direction of the connector (i.e. the starting position of the pin, which corresponds to the starting position of the wire harness). The bottom of the positioning fixture 1 is provided with a mounting bracket 9. The mounting bracket 9 is mounted on the worktable by a suction cup structure 10, which is convenient for installation and disassembly.

[0025] On the other two sides of the guide post 4, there are rectangular bosses 12. After the connector is inserted into the tooling cavity 2, the rectangular bosses 12 contact the inner wall of the connector's socket. The side and end face of the guide post 4 are provided with a second chamfer, which also makes it easy to insert the connector.

[0026] In this embodiment, the tooling cavity 2 is a circular hole structure, and the tooling cavity 2 and the connector are interference fit. Specifically, the tooling cavity 2 and the connector are slightly interference fit, which can facilitate the insertion / removal of the connector.

[0027] The positioning fixture body 1 on the end face of the tooling cavity 2 is provided with a limiting step hole 13. When the positioning surface of the connector reaches the limiting step hole 13, it indicates that the connector is inserted into place.

[0028] Direction indicator 8 is either an arrow or a connector model designation. In this embodiment, direction indicator 8 is a connector model designation, which makes it easy for workers to see at a glance the connector model corresponding to the positioning fixture 1.

[0029] The positioning fixture 1 and the guide post 4 are integrally molded, and both the positioning fixture 1 and the guide post 4 are made of plastic. The positioning fixture 1 and the guide post 4 are integrally injection molded, or manufactured by 3D printing.

[0030] In this embodiment, the mounting bracket 9 includes a connecting horizontal plate 14, which is connected to the bottom of the positioning fixture 1 by a first bolt 15. Support columns 16 are provided at the bottom of both ends of the connecting horizontal plate 14, and a suction cup structure 10 is located at the bottom of the support columns 16. The top surface of the support columns 16 has threaded holes, and the connecting horizontal plate 14 is locked into these holes by a second bolt 17 for easy assembly and disassembly. The connecting horizontal plate 14 has a waist hole 18, through which the first bolt 15 passes and is locked to the bottom of the positioning fixture 1. The waist hole 18 allows the mounting bracket 9 to be adapted to different models of positioning fixtures 1.

[0031] In one embodiment, the suction cup structure 10 is a vacuum suction cup, which is applied to a workbench with a smooth surface, such as a glass or marble workbench.

[0032] In one embodiment, the suction cup structure 10 is a magnetic suction cup, which is a switch magnetic suction cup (similar to the magnetic base of a dial indicator), and is applied to an iron workbench.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
