Furthermore, once the insulating base of the terminal block is damaged, the entire terminal block must be replaced, increasing costs. Summary of the Invention

[0006] As a preferred technical solution, each splicing block has a through hole on its top surface opposite the wiring hole, and each conductive post has a second screw hole on its outer wall surface opposite the through hole. Each second screw hole is threaded with a screw to press and fix the wire.
[0007] As a preferred technical solution, the clamping assembly includes multiple clamping plates. One end of each clamping plate is mounted on the inner wall of the wiring hole, and the other end is bent outward to form a guide section. The clamping channel between the clamping plates is smaller than the inner diameter of the wiring hole.
[0008] As a preferred technical solution, each of the splicing blocks has multiple snap-fit grooves on one side, and each of the splicing blocks has a snap-fit part protruding on the other side. The snap-fit parts are inserted into the snap-fit grooves, and both the snap-fit parts and the snap-fit grooves are hemispherical in shape.

[0013] The beneficial effects of this utility model are: the utility model has a simple structure and can install a corresponding number of splicing blocks according to the number of wires, which increases adaptability. After the splicing blocks are fixed, multiple fixing holes are formed between the splicing blocks. The device can be fixed in any equipment housing through these fixing holes. The splicing blocks can be positioned after rotation through the snap-fit part and snap-fit groove, which can make precise alignment and avoid misalignment. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0020] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.
[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a terminal block snap-fit device, comprising multiple splicing blocks 1, each splicing block 1 having mounting holes, each mounting hole having a conductive post 2 installed in the mounting holes, each conductive post 2 having wiring holes at both ends, each wiring hole having a clamping component for pre-fixing wires installed in the opening of the wiring hole, each splicing block 1 having a first screw hole 3 on one side, each splicing block 1 having a screw 4 installed at the other end, each screw 4 being threaded into an adjacent first screw hole 3, each splicing block 1 having an arc-shaped groove 6 on both sides, each adjacent arc-shaped groove 6 forming a fixing hole.
[0023] In this embodiment, the top surface of the splicing block 1 is provided with a through hole opposite the wiring hole, and the outer wall surface of the conductive post 2 is provided with a second screw hole opposite the through hole. The second screw hole is threaded with a screw 7 to press and fix the wire.
[0024] In this embodiment, each clamping component includes multiple clamping pieces 5. One end of each clamping piece 5 is mounted on the inner wall of the wiring hole, and the other end is bent outward to form a guide portion. The clamping channel between the clamping pieces 5 is smaller than the inner diameter of the wiring hole.
[0025] In this embodiment, each side of the splicing block 1 is provided with a plurality of snap-fit grooves 10, and the other side of the splicing block 1 protrudes to form snap-fit parts 9. The snap-fit parts 9 are all inserted into the snap-fit grooves 10, and both the snap-fit parts 9 and the snap-fit grooves 10 are hemispherical in shape.
[0026] In this embodiment, both the splicing block 1 and the screw 4 are made of insulating plastic material, which can separate the conductive posts and prevent them from conducting to each other.
[0027] In this embodiment, the conductive post 2 has a third screw hole on the side facing the first screw hole 3, which is opposite to the first screw hole 3. After the screw is threaded into the first screw hole, it can also enter the third screw hole. The third screw hole increases the service life and reduces the probability of wear.
[0028] In this embodiment, the conductive pillars 2 are all made of brass to ensure conductivity.
[0029] In this embodiment, the clamping piece 5 is made of an elastic metal material, which enables the inserted wire core to be clamped and positioned.
[0030] In use, install the corresponding number of splicing blocks according to the quantity of wires. During installation, the screws on the splicing blocks are threaded into the first and third screw holes on one side of the splicing block. The splicing blocks can be fixed together by the threaded connection, thereby forming different numbers of wiring holes. During the splicing process, the snap-fit part can snap into the snap-fit groove. The snap-fit part and the snap-fit groove can position the spliced splicing blocks, avoiding misalignment and increasing the accuracy of splicing.
[0031] Among them, after the splicing blocks are fixed together, the arc-shaped grooves on the splicing blocks will combine to form fixing holes. Any external bolt can pass through the fixing holes to fix the device to the fixed end of the equipment housing. The combination of fixing holes increases the number of fixable positions and increases adaptability.
[0032] During wiring, the core wires on the wire can be inserted between the clips. The inward clamping force of the clips can hold and position the inserted core wires, achieving a pre-positioning effect. After the screw is turned down, the inserted wires can be pressed and fixed to ensure the stability of the wiring.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
