[0022] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0024] Example

[0025] like Figure 1-4 As shown, a wire harness connector that prevents loosening includes a connector and a wire harness connecting tube that is detachably arranged on at least one side of the connector, wherein the wire harness connecting tube includes a first connecting tube 12 that is detachably connected to the connector and a second connecting tube 4 that is movably installed on the first connecting tube 12;

[0026] Among them, a pre-tightening mechanism is arranged between the first connecting tube 12 and the second connecting tube 4, and the pre-tightening mechanism includes a first magnetic block 13 arranged on the first connecting tube 12 and a second magnetic block 14 arranged on the second connecting tube 4. There is an attractive force between the first magnetic block 13 and the second magnetic block 14, and the attractive force makes the first connecting tube 12 and the second connecting tube 4 tend to approach each other.

[0027] Specifically, the harness connection tubes are used to connect the harnesses to be connected. The harnesses to be connected are connected with the terminal 9 or other harnesses in the connector. The harness connection tubes are formed by the first connection tube 12 and the second connection tube 4. The second connection tube 4 is pulled out for a distance, and then the harness enters the first connection tube 12 and the second connection tube 4 and extends into the connector to connect with the terminal or other harnesses. At this time, the second connection tube 4 has a tendency to approach each other under the action of the first magnetic block 13 and the second magnetic block 14, so that the second connection tube 4 provides pre-tightening force for the harness, so that the harness and the terminal or the harness and the harness always maintain a benign connection, reducing the probability of failure.

[0028] Furthermore, the second connecting tube 4 is threadedly connected to a pair of screws 5, and the rotating shaft of the screw 5 is connected to a connecting tube 16. A connecting space for fixing the wiring harness is formed between the pair of connecting tubes 16. By rotating the screw 5, the connecting tube 16 is moved toward the direction of the wiring harness, so that the wiring harness is fixed in the connecting space.

[0029] Furthermore, the connecting tube 16 is provided with a plurality of grooves at intervals along the circumferential direction. The grooves are arc-shaped, and the side of the connecting tube 16 facing the connecting space is a rough surface. The grooves are used to increase the contact area between the connecting tube 16 and the wiring harness, so that part of the insulating layer of the wiring harness is stuck in the grooves to increase the connection stability between the connecting tube 16 and the wiring harness. The rough surface is used to increase the friction coefficient between the connecting tube 16 and the wiring harness, thereby further increasing the connection stability between the connecting tube 16 and the wiring harness.

[0030] Furthermore, the second magnetic block 14 is provided with an annular connecting portion 15 , which is threadedly connected to the second connecting tube 4 , and the annular connecting portion 15 and the second magnetic block 14 are connected as a whole via an adhesive. The provision of the annular connecting portion 15 is conducive to the disassembly and assembly of the second magnetic block 14 .

[0031] Furthermore, an enlarged head is provided at one end of the first connecting tube 12 facing the second connecting tube 4 , the outer diameter of the enlarged head is smaller than the inner diameter of the second magnetic block 14 , and the enlarged head abuts against the second magnetic block 14 to prevent the second connecting tube 4 from slipping out of the first connecting tube 12 .

[0032] Furthermore, the connector includes a box body 1, an end cover 2 arranged on the box body 1, a first connecting pipe 12 is threadedly connected to the box body 1, an O-ring 11 is arranged between the first connecting pipe 12 and the box body 1, and the O-ring 11 is used for sealing.

[0033] Furthermore, a third connecting tube 10 and a terminal 9 are provided in the box 1. The third connecting tube 10 is used to support the wiring harness, which is beneficial to the connection between the wiring harness and the wiring harness or the wiring harness and the terminal 9.

[0034] Furthermore, the end cover 2 is provided with a positioning groove, and the box body 1 is provided with a positioning protrusion 8 adapted to the positioning groove; the positioning groove and the positioning protrusion 8 are used to position the end cover 2, reducing the difficulty of installation. And the positioning protrusion 8 adapted to the positioning groove also improves the sealing performance between the box body 1 and the end cover 2. The box body 1 is provided with a mounting seat 7, and the mounting seat 7 is provided with a mounting hole 6; the mounting seat 7 and the mounting hole 6 thereon facilitate the installation of the box body 1 on an external component. A fastener 3 is provided between the box body 1 and the end cover 2, and the box body 1 and the end cover 2 are connected by the fastener 3. The fastener is preferably a screw.

[0035] The above-mentioned technical features can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
