[0002] In modern electrical systems and electronic equipment, wire harness connectors are the core components for achieving circuit connectivity, and the reliability of their connection is directly related to the stable operation of the entire system.

[0003] A search revealed a utility model patent with patent authorization announcement number CN108336544B, which discloses a wire harness connector, comprising: a first base, having a first bottom plate and a first side plate, the first side plate and the first bottom plate together forming a first accommodating cavity; a first pressure plate, disposed in the first accommodating cavity and pressing on the wire harness within the first accommodating cavity; a first conductive connector, electrically connected to the wire harness in the first accommodating cavity, and the first conductive connector passing through the first pressure plate and extending out of the first accommodating cavity; a second base, fastened and fixed to the first base; the second base having a second bottom plate and a second side plate, the second side plate and the second bottom plate together forming a second accommodating cavity.

[0004] Traditional wire harness connectors mainly rely on plastic clips or metal springs of the male and female connectors for mechanical locking. However, these plastic clips or metal springs are prone to deformation after frequent insertion and removal of the connector, which can lead to loosening of the connector later. Utility Model Content

[0005] The purpose of this invention is to provide an adsorption-type anti-loosening wire harness connector, which solves the problem of existing wire harness connectors being prone to loosening later.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adsorption-type anti-loosening wire harness connector, including a female connector and a male connector, which are interlocked. An anti-loosening mechanism is provided above both the female connector and the male connector. The anti-loosening mechanism includes a bracket fixedly connected to the upper end of the male connector, and the bracket is L-shaped. A housing is fixedly connected to the bottom of the horizontal part of the bracket. A magnetic block is fixedly connected to the top of the inner side of the housing. A sliding shell is fixedly connected to the upper end of the female connector, and the position of the sliding shell corresponds to the position of the housing. A locking block is slidably connected to the top of the sliding shell. The locking block is provided through the sliding shell, and the upper end of the locking block is slidably connected to the inner side of the housing. The locking block and the magnetic block are attracted to each other.

[0007] Preferably, a limiting block is fixedly connected to the side of the locking block, and the limiting block is slidably connected inside the sliding shell. The limiting block limits the upward travel of the locking block.

[0008] Preferably, the limiting block is provided with ball bearings, which are slidably connected to the inner wall of the sliding shell. The ball bearings reduce the relative friction between the limiting block and the sliding shell.

[0009] Preferably, a guide rod is fixedly connected to the inner side of the vertical part of the bracket, and a slider is slidably connected to the outer side of the guide rod. A plastic insert plate is fixedly connected to the side of the slider near the box body. An insertion hole is provided on the side wall of the box body, and the position of the insertion hole corresponds to the position of the plastic insert plate. The position of the insertion hole corresponds to the top position of the locking block, and the top corner of the locking block is provided with a rounded chamfer. The end of the plastic insert plate is provided with a bevel. The bevel and the rounded chamfer cooperate to allow the plastic insert plate to be better inserted into the top of the locking block, so that the locking block is disengaged from the magnetic block.

[0010] Preferably, a travel stop is fixedly connected to the end of the guide rod, and the travel stop and the guide rod are an integral structure. The travel stop limits the movement of the slider and the plastic insert.

[0011] Preferably, a spring is sleeved on the outer side of the guide rod, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner wall of the bracket. The spring provides auxiliary repositioning for the slider.

A sliding button is fixedly connected to the top of the connecting block, and the sliding button is slidably connected to the upper end of the horizontal part of the bracket. The sliding button and connecting block facilitate the pushing and pulling of the slider and the plastic insert.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides an anti-loosening mechanism above the original female and male connectors. After the female and male connectors are plugged in, the locking block can be attracted by the magnetic block and inserted into the box. In this way, the locking block and the box can limit and lock the insertion direction of the female and male connectors, avoid accidental detachment caused by vibration, and thus improve the stability of the wire harness connection.

[0015] 2. The anti-loosening mechanism of this utility model is equipped with a manual unlocking component. The slider and plastic insert are moved laterally by the sliding button. The plastic insert enters through the insertion hole on the side of the box and separates the magnetic block and the locking block. The locking block falls by its own weight and separates from the box, thereby releasing the restriction on the female connector and the male connector, and then they can be separated.

[0024] Please see Figures 1-5Both the female connector 1 and the male connector 2 are equipped with an anti-loosening mechanism 3. The anti-loosening mechanism 3 includes a bracket 31 fixedly connected to the upper end of the male connector 2. The bracket 31 is L-shaped. A housing 32 is fixedly connected to the bottom of the horizontal part of the bracket 31, with the opening of the housing 32 facing downwards. A magnetic block 33 is fixedly connected to the top of the inner side of the housing 32. A sliding shell 34 is fixedly connected to the upper end of the female connector 1, and the position of the sliding shell 34 corresponds to the position of the housing 32. A locking block 35 is slidably connected to the top of the sliding shell 34, penetrating the sliding shell 34. The upper end of the locking block 35 is slidably connected to the inner side of the housing 32, and the locking block 35 engages with the magnetic block 33. A limiting block 36 is fixedly connected to the side of the locking block 35, and the limiting block 36 is slidably connected inside the sliding shell 34. The limiting block 36 limits the upward stroke of the locking block 35. The limiting block 36 is provided with a ball bearing 37, which is slidably connected to the inner wall of the sliding shell 34. By providing the ball bearing 37, the relative friction between the limiting block 36 and the sliding shell 34 can be reduced.

[0025] Please see Figures 3-5 A guide rod 38 is fixedly connected to the inner side of the vertical part of the bracket 31. A slider 39 is slidably connected to the outer side of the guide rod 38. A plastic insert plate 310 is fixedly connected to the side of the slider 39 near the box 32. An insertion hole 315 is provided on the side wall of the box 32, and the position of the insertion hole 315 corresponds to the position of the plastic insert plate 310. The position of the insertion hole 315 corresponds to the top position of the locking block 35, and the top corner of the locking block 35 is provided with a rounded chamfer. The end of the plastic insert plate 310 is provided with a bevel. The bevel and the rounded chamfer cooperate to allow the plastic insert plate 310 to be better inserted into the top of the locking block 35, so that the locking block 35 is disengaged from the magnetic block 33. A travel stop 311 is fixedly connected to the end of the guide rod 38, and the travel stop 311 and the guide rod 38 are an integral structure. The travel stop 311 limits the movement of the slider 39 and the plastic insert plate 310. A spring 312 is sleeved on the outer side of the guide rod 38. One end of the spring 312 is fixedly connected to the slider 39, and the other end is fixedly connected to the inner wall of the bracket 31. The spring 312 assists in the reset of the slider 39.

A sliding button 314 is fixedly connected to the top of the connecting block 313 and is slidably connected to the upper end of the horizontal part of the bracket 31. The sliding button 314 and the connecting block 313 facilitate the pushing and pulling of the slider 39 and the plastic insert plate 310.

[0026] The specific implementation process of this utility model is as follows: First, align and insert the female connector 1 and male connector 2 in the conventional manner. At this time, the L-shaped bracket 31 at the upper end of the male connector 2 is positioned above the female connector 1. After the male connector 2 is inserted into place, the magnetic block 33 inside the housing 32 on its bracket 31 will automatically generate magnetic attraction with the locking block 35 inside the sliding shell 34 on the female connector 1. The locking block 35 slides upward into the housing 32, completing the locking of the female connector 1 and the male connector 2, thereby effectively preventing the connector from loosening due to vibration. When it is necessary to separate the connector... When connecting the connector, simply slide the slider 39 along the guide rod 38 using the slider 314 and connecting block 313, simultaneously stretching the spring 312. At the same time, the plastic insert 310 on the slider 39 is inserted into the insertion hole 315 on the side wall of the housing 32. The beveled front end of the plastic insert 310 abuts against the rounded chamfer at the top of the locking block 35, applying a downward force, thus separating the locking block 35 from the magnetic block 33. The locking block 35 falls under its own weight and separates from the housing 32, achieving mechanical unlocking. Then, the male connector 2 can be safely pulled out, completing the separation. After releasing the slider 314, the spring force of the spring 312 will automatically reset the plastic insert 310 for future use.
