[0026] Please refer to Figures 1-6 , the present invention provides a technical solution for a wire harness plugging and unplugging mechanism: a wire harness plugging and unplugging mechanism, including a plugging and unplugging female head seat 1, and further including: a positioning component 3, the positioning component 3 includes a connecting block 31, a positioning hole 32 opened on one side of the connecting block 31, a connecting groove 33 and an inner cavity 34 opened on one side of the plugging and unplugging female head 11, a moving hole 35 opened at the bottom of the inner cavity 34, a connecting plate 36 arranged inside the inner cavity 34, a positioning block 37 connected to the bottom of the connecting plate 36, a support spring 38 arranged at the upper end of the connecting plate 36 and a connecting column 39, a pulling block 310 arranged at the upper end of the connecting column 39, and a connecting hole 311 opened at the top of the inner cavity 34.

[0027] Among them, the plugging and unplugging female head 11 is located on one side of the plugging and unplugging female head seat 1, a slot 12 is opened inside the plugging and unplugging female head 11, a plugging and unplugging male head 21 is connected to one side of the plugging and unplugging male head seat 2, a limit strip 22 is connected to one side of the plugging and unplugging male head 21, and wire harnesses 4 are arranged on the outer sides of both the plugging and unplugging female head seat 1 and the plugging and unplugging male head seat 2, which is beneficial for the plugging and unplugging male head 21 to be adapted to the slot 12.

[0028] In addition, the connection block 31 and the plug-in male head seat 2 are fixedly connected. The number of connection blocks 31 is four groups and they are distributed in an array. One side edge of the connection block 31 is an arc-shaped structure. The positioning hole 32 penetrates through the middle of the connection block 31. The number of connection grooves 33 is equal to the number of connection blocks 31, and they are adapted to each other. The number of inner cavities 34 is equal to the number of connection grooves 33, and the inner cavity 34 is a rectangular structure. The inner cavity 34 and the connection groove 33 are connected through a moving hole 35. The connecting plate 36 is a flat rectangular structure and is adapted to the inner cavity 34. The positioning block 37 and the connecting plate 36 are fixedly connected. One side edge of the positioning block 37 is an arc-shaped structure. The positioning block 37 is adapted to the positioning hole 32. The connecting column 39 and the connecting plate 36 are fixedly connected. The two ends of the support spring 38 are respectively connected to the connecting plate 36 and the inner cavity 34. The connecting column 39 is adapted to the connecting hole 311. The connecting column 39 and the pulling block 310 are fixedly connected, thus facilitating the quick positioning between the plug-in female head 11 and the plug-in male head 21.

[0029] For this wire harness plugging and unplugging mechanism, during the use of the wire harness plugging and unplugging mechanism, the plug-in male head 21 and the limiting strip 22 on one side of the plug-in male head seat 2 are inserted into the slot 12 inside the plug-in female head 11, so that the two are connected and the internal terminals are connected. At the same time, rapid positioning is carried out through the positioning component 3, thereby realizing the plugging and unplugging connection of the wire harness 4.

[0030] It should be noted that through the setting of the positioning component 3, when connecting between the plug-in female head 11 and the plug-in male head 21, when the user inserts the plug-in male head 21 and the limiting strip 22 into the inside of the slot 12, the connection block 31 is inserted into the inside of the connection groove 33, so that the arc surface of the connection block 31 contacts the arc surface of the positioning block 37, causing the positioning block 37 to be forced to contract along the moving hole 35. At the same time, the connecting plate 36 moves along the inside of the inner cavity 34, the support spring 38 is compressed, and the connecting column 39 drives the pulling block 310 to move outward along the inside of the connecting hole 311 until the bottom of the connection block 31 contacts the bottom of the connection groove 33, making the positioning hole 32 correspond to the positioning block 37. Under the elastic potential energy of the support spring 38, the positioning block 37 is quickly inserted into the inside of the positioning hole 32, thereby positioning the connection block 31 and further positioning between the slot 12 and the plug-in male head 21, achieving a quick assembly effect.

[0031] It should be noted that when it is necessary to disassemble and limit the contact between the plug-in male head 21 and the slot 12, the user only needs to pull the pulling block 310, so that the pulling block 310 drives the connecting column 39 to pull outward along the inside of the connecting hole 311, and at the same time drives the connecting plate 36 and the positioning block 37 to be pulled out along the inside of the moving hole 35 and the positioning hole 32, so that the plug-in male head 21 can be pulled out from the slot 12. The structure is simple, the operation is convenient, and it is convenient to plug and unplug the wire harness 4.
