Description

Technical Field

[0001] The utility model relates to the technical field of wiring harness connector terminals, in particular to a torque assist tool. Background Art

[0002] With the continuous development of the automotive industry, many high-voltage connector terminal assembly processes require torque. The Amphenol HVSC1P80FV connector, widely used in commercial vehicle wiring harnesses, suffers from the following technical deficiencies during crimping and assembly: 1) The female connector terminal requires hand-held securement, making it difficult for a single person to operate; and 2) manual hand-held securement of the connector makes torque application prone to errors and can scratch the connector surface.

[0003] Therefore, how to design a torque-assisted tooling has become an urgent problem to be solved. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a torque-assisted tooling to solve at least one of the above technical problems.

[0005] The technical solution of the utility model is: a torque-assisted tooling, comprising a tooling body that can be fixedly installed, the tooling body being an L-shaped block, three sections of stepped countersunk holes being provided in the middle of the L-shaped block, the three sections of stepped countersunk holes being a Chinese-character structure, the Chinese-character structure penetrating the top surfaces of the horizontal plate and the vertical plate of the L-shaped block, a female end of a connector being provided in the Chinese-character structure; the small end of the three sections of stepped countersunk holes being an open slot, the open slot being located at one end of the vertical plate of the L-shaped block away from the horizontal plate, the two sides of the open slot being tail blocks, a large square wiring harness of a connector being provided in the open slot.

[0006] The utility model adopts a tooling body that can be fixedly installed. The three-section stepped countersunk hole of the Chinese-character structure is used to place the female end of the connector. The gap of the tail block can be used to place the large square wiring harness of the connector. The female end of the connector does not need to be fixed by hand. During the torque operation, it is not easy to make errors, and the surface of the connector is avoided from being scratched during the process of holding the female end of the connector. This solves the technical defects that the female end of the connector is difficult to operate by one person when being fixed by hand, and the connector is easily prone to errors and may scratch the surface of the connector during the torque operation when being fixed by hand.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0011] Example 1: A torque assist tool, referring to Figure 1 The utility model adopts a tool body that can be fixedly installed. The tool body is an L-shaped block. The middle part of the L-shaped block is provided with three sections of stepped countersunk holes 1. The three sections of stepped countersunk holes 1 are in a Chinese-character structure. The Chinese-character structure runs through the top surface of the horizontal plate and the vertical plate of the L-shaped block. The female end of the connector is provided in the Chinese-character structure. The small end of the three sections of stepped countersunk holes 1 is an open slot 2. The open slot 2 is located at the end of the vertical plate of the L-shaped block away from the horizontal plate. The two sides of the open slot 2 are tail blocks. The large square wiring harness of the connector is provided in the open slot 2. The utility model adopts a tool body that can be fixedly installed. The three sections of stepped countersunk holes in the Chinese-character structure are used to place the female end of the connector. The gap of the tail block can be used to place the large square wiring harness of the connector. The female end of the connector does not need to be fixed by hand. During the torque operation, it is not easy to make errors. The surface of the connector is avoided from being scratched during the hand-held female end. The technical defects of the female end of the connector being difficult to operate by one person and the manual hand-held fixation of the connector being prone to errors and possible scratches on the surface of the connector are solved.

[0012] Example 2: Based on Example 1, the large middle end of the three-stage stepped countersunk hole 1 is a first rectangular countersunk hole, the long side of which penetrates the top surface of the horizontal and vertical plates of the L-shaped block. This utility model uses the long side of the first rectangular countersunk hole to penetrate the top surface of the horizontal and vertical plates of the L-shaped block for accommodating the female end of the connector.

[0013] Example 3: Based on Example 2, one end of the three-stage stepped countersunk hole 1 is a second rectangular countersunk hole. The second rectangular countersunk hole is located on the top surface of the horizontal plate of the L-shaped block. The long side of the second rectangular countersunk hole penetrates the short side of one end of the first rectangular countersunk hole. This utility model uses the second rectangular countersunk hole located on the top surface of the horizontal plate of the L-shaped block to achieve horizontal and vertical fixation of one end of the connector female end.

[0014] Example 4: Based on Example 2, the opening slot 2 is a third rectangular countersunk hole, which penetrates the short side of the other end of the first rectangular countersunk hole. The utility model uses tail blocks on both sides of the opening slot to achieve horizontal and vertical fixation of the other end of the connector female end.

[0015] Embodiment 5: Based on embodiment 4, the bottom surface of the open groove 2 is higher than the bottom surface of the first rectangular countersunk hole. The present invention adopts the method of placing a large square wire harness of a connector by making the bottom surface of the open groove higher than the bottom surface of the first rectangular countersunk hole.

[0016] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
