Of course, other materials in the prior art can also be filled, and the present invention does not further limit this.
[0046] The pressing plate 4 is movably arranged on the mounting body 1, and a plurality of driving plates 5 are arranged on the pressing plate 4.

Specifically, the pressing plate 4 is operated by pressing, the driving plate 5 is driven to act by the pressing plate 4, and the driving plate 5 enters the wiring block 3 through the driving opening 321 and contacts the clamping end 34. In the process of the driving plate 5 gradually entering the wiring block 3, the clamping end 34 is pushed to gradually move towards the fixed end 33 by the driving plate 5. Since the first wire is placed between the fixed end 33 and the clamping end 34, after the clamping end 34 moves, the first wire will be clamped between the fixed end 33 and the clamping end 34, and the fixing of the first wire is completed.
[0047] The technical solution of the utility model is to arrange a plurality of wiring blocks 3 in the mounting block 2 arranged on the mounting body 1. When it is necessary to connect the wires, the wires are inserted through the wire entry hole 22, passed through the wire entry port 311, and then placed between the fixed end 33 and the clamping end 34. The clamping plate 4 is operated to drive the plurality of driving plates 5 to move, and the plurality of driving plates 5 contact the plurality of clamping ends 34, respectively push the plurality of clamping ends 34 to move to the positions of the plurality of fixed ends 33, and clamp the wires placed between the clamping ends 34 and the fixed ends 33 during the movement, thereby completing the fixing of the wires. In addition, the fixed end 33 is connected to the circuit board through another wire passing through the wire outlet hole 23, and the connection between the wire and the circuit board is completed after the clamping end 34 has moved. Compared with the prior art, the connection between the wire and the circuit board can be achieved without the need for welding, thereby improving the overall production efficiency during mass production, and further reducing the production cost.

When the clamping plate 4 is pressed, the elastic member 12 will be squeezed by the first slider and the second slider respectively; and when the first wire needs to be separated from the connecting block, the clamping plate 4 is separated from the mounting block 2, and the clamping plate 4 can be reset under the action of the elastic member 12; it should be noted that the driving groove 11 also needs to be sealed to prevent the clamping plate 4 from being separated from the driving groove 11 when the elastic member 12 is reset; specifically, the sealing adopts the rubber block of the prior art, etc., and the utility model does not further limit this; among them, the preferred elastic member 12 is preferably a spring.

After continuously pressing the pressing plate 4, the locking arm 41 enters the locking groove 13. At the same time, the spring is compressed by the locking arm 41. Since a locking frame is arranged on the locking arm 41, when the locking arm 41 enters the locking groove 13, the locking block 14 is aligned with the locking frame. At this time, the locking arm 41 does not press the locking block 14, and the locking block 14 enters the locking frame after resetting under the action of the spring, completing the limitation of the locking arm 41, and further realizing the limitation of the pressing plate 4; As Figure 2 As shown, an inclined surface is arranged on the locking block 14. When the locking arm 41 contacts the locking block 14, it can contact the inclined surface and make the locking block 14 gradually enter the locking groove 13.

The pressing plate 4 gradually resets under the action of the elastic member 12, and after the driving plate 5 is gradually separated from the clamping end 34, the first wire is taken out from the wire inlet hole 22.
[0052] Since the surface of the wire core of the wire is relatively smooth, to increase the clamping force of the fixing end 33 and the clamping end 34 on the wire core of the first wire, preferably, pressing protrusions 35 are arranged on both the fixing end 33 and the clamping end 34, and the pressing protrusions 35 on the fixing end 33 and the clamping end 34 are oppositely arranged; in this way, when the wire core of the first wire is clamped by the fixing end 33 and the clamping end 34, the friction force between the fixing end 33 and the clamping end 34 and the wire core of the first wire can be increased, improving the clamping effect.
[0053] As Figure 8 、 12As shown in FIGS. 12 and 13, a first limiting shell 36 and a second limiting shell 39 are oppositely arranged inside the installation shell 32, and a first sliding groove 37 and a second sliding groove are respectively formed between the first limiting shell 36 and the second limiting shell 39 and the bottom surface of the installation shell 32; the moving plates at the bottom of the clamping ends 34 are respectively inserted into the first sliding groove 37 and the second sliding groove; as Figure 13 shown, after the driving plate 5 contacts the clamping end 34, the moving plates on both sides of the clamping end 34 slide in the first sliding groove 37 and the second sliding groove respectively, thereby changing the position of the clamping end 34; in addition, when disassembling the first wire (such as when the first wire is broken or other components need to be repaired), when the driving plate 5 gradually separates from the clamping end 34, the clamping end 34 needs to be reset to facilitate subsequent reinstallation; in the present invention, preferably, a first reset member 38 and a second reset member are arranged in both the first sliding groove 37 and the second sliding groove, and the first reset member 38 and the second reset member are both connected to the moving plate; when in the wire connection state; after the moving plates move in the first sliding groove 37 and the second sliding groove respectively, they will pull the first reset member 38 and the second reset member; and when the driving plate 5 separates from the clamping end 34, the first reset member 38 and the second reset member are reset under the action of elastic deformation, thereby pulling the moving plates on both sides of the clamping end 34 to move in the first sliding groove 37 and the second sliding groove respectively, thereby resetting the clamping end 34.
