[0038] The plug-in panel 4 is provided with a guide wire locker 7 located at one side of the socket seat 6. The guide wire locker 7 is used to secure the cable 8 on the plug-in panel 4 and has a reliable anti-loosening function.

[0039] Specifically, the guide wire lock 7 includes a wire sleeve 71, a support 72, and a power-assist plug-in mechanism 73 and a trigger shaft 74 arranged on the support 72. The outer fixed sleeve of the cable 8 is provided with a wire sleeve 71 near one end. The specifications of the wire sleeves 71 on different cables 8 are the same. One end of the wire sleeve 71 is fixedly connected with a plug 711 adapted to the socket seat 6, and its outer peripheral wall is snap-fitted and connected with the power-assist plug-in mechanism 73. The specifications of the plug 711 and the socket seat 6 are determined according to requirements. That is to say, the corresponding plugs 711 on multiple cables 8 have USB structures, type-c structures, etc. The function of the power-assist plug-in mechanism 73 is to assist the operator to perform labor-saving plugging and unplugging of the plug 711. The trigger shaft 74 is slidably connected to the support 72. When the trigger shaft 74 slides, the plug 711 and the socket seat 6 are controlled to be plugged in and out through the power-assisted plug-in mechanism 73. That is to say, the trigger shaft 74 is a component manually controlled by the operator.

When the plug 711 and the socket seat 6 are plugged in, the wire sleeve 71 is locked on the plug-in panel 4 to realize the wire locking function.

[0040] Furthermore, the support 72 is provided with a positioning pile 722 and a guide shaft 721 fixedly arranged at the bottom of the positioning pile 722, one end of the positioning pile 722 is fixedly connected to the plug-in panel 4, the positioning pile 722 is located on the outside of the jack seat 6, the axis of the guide shaft 721 is parallel to the inner hole of the jack seat 6, and the auxiliary plug-in mechanism 73 includes a guide plate 731 axially slidingly matched with the guide shaft 721, the guide plate 731 is perpendicular to the guide shaft 721, and one end of the guide plate 731 is provided with a U-shaped slot 7311, the opening direction of the U-shaped slot 7311 is toward the dividing ball 5, and the outer peripheral wall of the wire clamp 71 is provided with two symmetrically distributed limiting planes 712 which are engaged with the U-shaped slot 7311. That is to say, the wire clamp 71 moves laterally so that the limiting plane 712 cannot rotate or move axially after entering the U-shaped slot 7311. At this time, when the guide plate 731 moves axially along the guide shaft 721, it can drive the wire clamp 71 to move, so that the plug 711 can be accurately plugged into the jack seat 6.

[0041] The power-assisted plug-in mechanism 73 includes a transmission mechanism 732 for driving the guide plate 731 to slide, and the movement of the transmission mechanism 732 is triggered by the trigger shaft 74 .

[0042] Specifically, the transmission mechanism 732 includes a U-shaped limit plate 7321, a gate-shaped connecting rod 7322 and a gate-shaped driving frame 7323. The two sides inside the U-shaped limit plate 7321 and the two sides outside the guide plate 731 are laterally slidably connected. The outer wall of the positioning pile 722 is fixedly connected with a guide rod 7221 located on one side of the guide shaft 721. The cross bar on the gate-shaped connecting rod 7322 and the end of the guide rod 7221 away from the positioning pile 722 are rotatably connected. The two free ends of the gate-shaped connecting rod 7322 are respectively rotatably connected to the two sides of the U-shaped limit plate 7321. In specific implementation, a connecting shaft rotatably connected to the free end of the gate-shaped connecting rod 7322 can be welded on both sides of the U-shaped limit plate 7321. The crossbeam and guide rod 7221 on the door-type drive frame 7323 are slidably connected, and the plane where the door-type drive frame 7323 is located is perpendicular to the guide shaft 721. Baffle rods 73231 close to the free end are arranged on both sides of the door-type drive frame 7323, and the baffle rod 73231 and the side of the door-type connecting rod 7322 opposite to the wire sleeve 71 are abutted. When the door-type drive frame 7323 is controlled to move up in the axial direction of the guide shaft 721, the baffle rod 73231 will push the door-type connecting rod 7322 to swing up. When the door-type connecting rod 7322 swings up, it will drive the U-shaped limit plate 7321 to slide relative to the guide plate 731. At this time, the guide plate 731 will move axially along the guide shaft 721. This transmission method makes the plugging and unplugging of the plug 711 and the jack seat 6 more accurate and labor-saving. The trigger shaft 74 is slidably connected to the guide rod 7221 and one end thereof is fixedly connected to the crossbeam on the door-shaped drive frame 7323, that is, manually pulling the trigger shaft 74 up and down can control the plugging and unplugging operation of the plug 711 and the socket seat 6.

One side of the two vertical rods on the door-shaped connecting rod 7322 is fixedly connected to a triangular plate 73221. The stop rod 73231 is sleeved with a roller 732311 that rolls with the triangular plate 73221. The roller 732311 The setting can reduce the friction between the blocking rod 73231 and the door-type connecting rod 7322, wherein the setting of the triangular plate 73221 has the function of self-locking after the plug 711 and the socket seat 6 are plugged in, that is, when the roller 732311 passes over the tip of the triangular plate 73221, it will be blocked by the tip. At this time, the plug 711 and the socket seat 6 will not loosen after being plugged in, and the trigger shaft 74 is pulled downward. At this time, the roller 732311 will move downward and pass over the tip of the triangular plate 73221, and the support spring 7324 will use the elastic force to push the guide plate 731 downward, thereby pulling out the plug 711.

[0044] Furthermore, the blind end of the U-shaped limit plate 7321 is opposite to the U-shaped slot 7311, and an elastic telescopic limit strut 73212 is fixedly connected to the blind end of the U-shaped limit plate 7321. The action end of the elastic telescopic limit strut 73212 is fixedly connected to a pressure plate 732121 opposite to the U-shaped slot 7311. The elastic telescopic limit strut 73212 adopts a common two-section telescopic structure with a built-in spring, and its function is to assist the pressure plate 732121 to press the wire clamp 71 so that the wire clamp 71 is fastened in the U-shaped slot 7311. At the same time, it also has the function of assisting the U-shaped limit plate 7321 to slide relative to the guide plate 731, and has the function of assisting the guide plate 731 to slide downward along the guide shaft 721, so that the separation operation of the plug 711 and the jack seat 6 is more labor-saving.

[0045] In this embodiment, the dividing ball 5 includes a central axis 51 and a guide sleeve 53. One end of the central axis 51 is fixedly connected to one side of the plug-in panel 4 and the other end is fixedly connected to a limiting ball 511. The height of the limiting ball 511 is lower than the guide wire locker 7. The outer ball wall of the limiting ball 511 is provided with a wire groove 5111 that is evenly distributed circumferentially relative to the axis of the central axis 51. The guide sleeve 53 is sleeved on the central axis 51 and the two are axially elastically slidably connected. In specific implementation, it is preferred that a reset spring 54 is sleeved on the central axis 51 and located between the limiting ball 511 and the guide sleeve 53. The bottom of the limiting ring 531 is fixedly connected to a pull rod 5312 coaxial with the central axis 51 through a connecting rod. This pull rod 5312 is an operating component for manually controlling the downward movement of the limiting ring 531. The outer wall of the guide sleeve 53 is connected to a limiting ring 531 which abuts against the lower part of the limiting ball 511 through a connecting rod. A yielding notch 5311 is provided on the ring body of the limiting ring 531, which is located on one side of the wire groove 5111 and is staggered relative to the wire groove 5111. The inner ring diameter of the limiting ring 531 is smaller than the ball diameter of the limiting ball 511. One or more cables 8 can share one wire groove 5111, and the cable 8 will be blocked by the limiting ring 531. When it is necessary to move out the cable 8 passing through the wire groove 5111, the limiting ring 531 is pulled downward, and the area around the yielding notch 5311 is in an empty state, and then the current cable 8 can be taken out from the yielding notch 5311.

[0046] When the locking cam 731 is in the unlocking state, the locking cam 731 is in the unlocking state, and the locking cam 731 is in the unlocking state, so that the locking cam 731 is in the unlocking state, and the locking cam 731 is in the unlocking state.
