[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] Please refer to Figures 1 - 3 , in the figure, a misaligned terminal block is shown, which includes a terminal block body 1. A jack 2 is provided on the front surface of the terminal block body 1. A wiring head 6 is arranged inside the jack 2, and a connection component 20 is arranged at the upper end of the wiring head 6.

[0021] Please refer to Figures 1 - 2 , the connection component 20 includes a positioning convex block one 7 and a positioning convex block two 8. A positioning convex block one 7 is fixedly arranged on the upper end surface of the wiring head 6, and positioning convex block two 8s are fixedly arranged on both the left and right sides of the lower end surface of the wiring head 6. A positioning groove one 3 is provided at the top inside the jack 2, and positioning groove two 4s are provided on both the left and right sides of the bottom inside the jack 2. The positioning groove one 3 and the positioning groove two 4 are respectively matched with the positioning convex block one 7 and the positioning convex block two 8.

[0022] In this embodiment: The positioning groove one 3 and the positioning groove two 4 are respectively matched with the positioning convex block one 7 and the positioning convex block two 8, so that the wiring head 6 can only be inserted into the jack 2 in one direction, thus avoiding the occurrence of the phenomenon of incorrect insertion direction.

[0023] Please refer to Figure 1 、 Figure 3 , a wiring post 5 is fixedly arranged on the back inside the jack 2, and there are five wiring posts 5, which are distributed in a staggered manner up and down. A wiring groove 9 is provided on the front side of the wiring head 6, and the wiring groove 9 is matched with the wiring post 5. Clamping components 21 are arranged on both the left and right sides of the wiring head 6.

[0024] In this embodiment: The wiring posts 5 are distributed in a staggered manner up and down, which can effectively prevent the misinsertion of connectors similar to the wiring head 6 into the jack 2, and can cooperate with the positioning convex block one 7 and the positioning convex block two 8 to avoid errors again.

[0025] Working principle: First, the operator takes out the terminal block body 1 and the connection head 6 with the wires connected. Align the positioning protrusion one 7 and the positioning protrusion two 8 on the connection head 6 with the positioning groove one 3 and the positioning groove two 4 inside the jack 2. Then insert the connection head 6 into the jack 2 inside the terminal block body 1. At this time, the position of the terminal post 5 matches that of the connection slot 9, and the terminal post 5 can thus be inserted into the inside of the connection slot 9, completing the wiring operation. The settings of the positioning protrusion one 7 and the positioning protrusion two 8 and the offset setting of the terminal post 5 can effectively avoid the phenomenon of incorrect insertion direction, thus ensuring the work quality of the operator.

[0026] Embodiment 2

[0027] Please refer to Figures 3 - 4 , this embodiment further illustrates Embodiment 1. In the figure, the engaging component 21 includes a spring 11 and a clamping block 12. Installation grooves 10 are formed on both the left and right sides of the connection head 6. Springs 11 are fixedly arranged on the inner side walls of the installation grooves 10, and there are two springs 11. The other ends of the springs 11 are fixedly provided with clamping blocks 12. Claw slots 13 are formed on both the left and right sides inside the jack 2, and the claw slots 13 match the clamping blocks 12.

[0028] In this embodiment: First, the operator presses the clamping block 12 into the inside of the installation groove 10. At this time, the spring 11 is compressed. Then insert the connection head 6 into the inside of the jack 2. When the connection head 6 is inserted properly, the clamping block 12 moves outward under the action of the resilience of the spring 11, and the clamping block 12 can thus be engaged into the inside of the claw slot 13, effectively preventing the connection head 6 from falling off.

[0029] Please refer to Figure 4 , cavities 14 are formed inside the left and right side walls of the terminal block body 1. Pressing plates 15 are arranged on both the left and right sides of the terminal block body 1. A connecting rod 16 is fixedly arranged on the inner side of the pressing plate 15. The other end of the connecting rod 16 is arranged inside the cavity 14, and a first pushing plate 17 is fixedly arranged at the other end of the connecting rod 16.

[0030] In this embodiment: When it is necessary to disassemble the connection head 6, the operator presses the pressing plate 15 inward. The pressing plate 15 can thus drive the connecting rod 16 and the first pushing plate 17 to move inward. The first pushing plate 17 can thus push the clamping block 12 back into the inside of the installation groove 10, and the operator can thus pull the connection head 6 outward to complete the disassembly of the connection head 6.

[0031] Please refer to Figure 4 , C-shaped rods 18 are fixedly arranged on both the upper and lower sides outside the first pushing plate 17. A second pushing plate 19 is fixedly arranged at the other end of the C-shaped rod 18, and the second pushing plate 19 is in the same plane as the first pushing plate 17.

[0032] In this embodiment, when the first push plate 17 moves inward, the second push plate 19 can be driven to move inward synchronously by the C-shaped rod 18. When the pressing plate 15 cannot be pressed any further, the second push plate 19 is in contact with the outer side of the terminal 6 at this time, thus playing a role in limiting the movement of the first push plate 17. The clamping block 12 is at the same plane as the inner side wall of the jack 2 at this time, facilitating the disassembly of the terminal 6 and effectively preventing the first push plate 17 from extending into the installation groove 10 and affecting the disassembly of the terminal 6.
