[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the utility model provides a technical solution for a connector terminal assembly structure, including an insulating box 1, the inner wall of the insulating box 1 is threadedly connected with an insulating bolt, the diameter of the insulating bolt is adapted to the threaded hole on the surface of the connecting block 203, and the connecting block 203 can be effectively fixedly connected to the right inner wall of the insulating box 1 by tightening the bolt.

[0024] like Figure 1 、 Figure 2 and Figure 3As shown, a connecting mechanism 2 is provided inside the insulating box 1, and the connecting mechanism 2 includes two movable plates 201. The outer surfaces of the two movable plates 201 are slidably connected to the insulating box 1. A slider is fixedly installed on the outer surface of the movable plate 201, and the slider slides into the inner wall of the insulating box 1, thereby making the movable plate 201 more stable when moving.

[0025] The outer surface of the movable plate 201 is hinged with a swing rod 202 via a pin, and the end of the swing rod 202 away from the movable plate 201 is hinged with a connecting block 203 via a pin. The connecting block 203 moves left and right inside the insulating box 1, which can effectively make the swing rod 202 swing and drive the two movable plates 201 to move closer to or away from each other.

[0026] The inner wall of the movable plate 201 is slidably connected with a fixed post 204, and the inner wall of the movable plate 201 is sleeved with a support spring 205, one end of the support spring 205 is fixedly connected to the fixed post 204, and the end of the support spring 205 away from the fixed post 204 is fixedly connected to the movable plate 201. Through the resilience of the support spring 205, the fixed post 204 can be effectively pushed into the fixing hole 303 to fix the terminal body 302.

[0027] The inner wall of the connecting block 203 is slidingly connected to a limiting rod 1 206, and both ends of the limiting rod 1 206 are fixedly connected to the insulating box 1. The outer surface of the limiting rod 1 206 is sleeved with a supporting spring 207, and one end of the supporting spring 207 is fixedly connected to the connecting block 203, and the end of the supporting spring 207 away from the connecting block 203 is fixedly connected to the insulating box 1. When the supporting spring 207 is in the initial state, the connecting block 203 will be fixed to the left side inside the insulating box 1. When the connecting block 203 moves to the right, the resilience of the supporting spring 207 will exert a leftward pulling force on the connecting block 203, thereby making the connection between the connecting block 203 and the terminal body 302 tighter.

[0028] The inner wall of the insulating box 1 is fixedly connected with a limiting telescopic rod 208, the telescopic end of the limiting telescopic rod 208 is fixedly connected to the movable plate 201, the outer surface of the limiting telescopic rod 208 is sleeved with a support spring three 209, one end of the support spring three 209 is fixedly connected to the insulating box 1, and the end of the support spring three 209 away from the insulating box 1 is fixedly connected to the movable plate 201. Through the setting of the limiting telescopic rod 208, the movable plate 201 is effectively fixedly supported.

[0029] like Figure 1 、 Figure 2 and Figure 4As shown, a disassembly mechanism 3 is provided on the outside of the insulating box 1, and the disassembly mechanism 3 includes a fixing box 301, and a terminal body 302 is fixedly connected to the inner wall of the fixing box 301. The outer surface of the terminal body 302 is provided with a fixing hole 303 adapted to the fixing column 204. The fixing column 204 slides into the interior of the fixing hole 303, effectively assembling and connecting the terminal body 302, making the terminal body 302 more stable and less likely to shake inside the insulating box 1.

[0030] The outer surface of the terminal body 302 is slidably connected to two clamping metal plates 304, and the outer surfaces of the two clamping metal plates 304 are fixedly connected to moving block 1 305 and moving block 2 306. By moving the clamping metal plates 304 closer to each other, the external wiring can be effectively fixed and clamped.

[0031] The inner wall of the fixed box 301 is rotatably connected to an insulating screw rod 307, and the outer surface of the insulating screw rod 307 is threadedly connected to the moving block 1 305. By rotating the insulating screw rod 307, the two moving blocks 1 305 can be effectively driven to move relative to each other at the same time.

[0032] The inner wall of the second moving block 306 is slidably connected to the second limiting rod 308, and both ends of the second limiting rod 308 are fixedly connected to the fixed box 301. Through the setting of the second limiting rod 308, the two clamping metal plates 304 are more stable when moving relative to each other.

[0033] When the present application is used in practice: first, the connecting end of the terminal body 302 is abutted against the connecting end of the connecting block 203. Secondly, the fixing box 301 is pushed to drive the terminal body 302 to move to the right, so that the terminal body 302 is deep into the interior of the insulating box 1. The right movement of the terminal body 302 will push the connecting block 203 to slide to the right on the surface of the limit rod 1 206. At this time, the supporting spring 207 will be stretched and deformed under the force. During the movement of the connecting block 203, the swing rod 202 is driven to swing. The swing rod 202 swings and pulls the two movable plates 201 to move closer to each other in the interior of the insulating box 1. The relative movement of the movable plate 201 effectively drives the fixed clamping column 204 in its inner wall to be stuck in the interior of the fixing hole 303. At this time, by tightening the insulating bolt on the right inner wall of the insulating box 1 and the connecting block 2 The threaded holes on the surface of 03 are threadedly connected, thereby effectively completing the assembly connection of the terminal body 302, thereby effectively avoiding the situation when the terminal body 302 is disassembled and connected, because the terminal body 302 and the connecting block 203 are tightly connected and need to be pulled out and plugged with force, resulting in the terminal body 302 being deformed by force and damaged, thereby reducing the service life of the terminal body 302. By extending the external wire into the fixed box 301 and contacting the terminal body 302, the insulating screw rod 307 is rotated at this time to drive the two moving blocks 305 to move closer to each other. The relative movement of the moving block 305 drives the clamping metal plate 304 on its surface to slide closer to each other on the surface of the terminal body 302, effectively clamping and fixing the external wire, simple operation, and convenient for the later maintenance work of the staff.
