The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0025] In some embodiments, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a through-type terminal block that is not fully assembled. Figure 2 This is a schematic diagram of the structure of a through-type terminal block after assembly. The present invention provides a through-type terminal block, including: a terminal box 1, a conductive terminal 2, and a fixing component 3. A first limiting part 1b is provided on the first side wall of the terminal box 1, and a second limiting part 1c is provided on the second side wall in cooperation with the first limiting part 1b. The first limiting part 1b can be detachably connected to the second limiting part 1c of another terminal box 1. A cavity 1a is provided in the terminal box 1 that penetrates the terminal box 1.

[0026] The conductive terminal 2 is placed in the terminal box 1 through the cavity 1a, and the conductive terminal 2 is provided with a wiring through hole 2a that penetrates the conductive terminal 2;

[0027] The fixing component 3 passes through the first connecting component 1d on the terminal box 1 and the second connecting component 2b on the conductive terminal 2 in sequence, and is connected to the wiring through hole 2a.

[0028] Specifically, the first limiting part 1b can be a protrusion, and the second limiting part 1c can be a groove; the first limiting part 1b can be a slider, and the second limiting part 1c can be a groove. If there are multiple first limiting parts 1b and second limiting parts 1c, some of the first limiting parts 1b can be protrusions, some of the second limiting parts 1c can be grooves, some of the first limiting parts 1b can be sliders, and some of the second limiting parts 1c can be grooves.

[0029] The number and direction of the first limiting part 1b and the second limiting part 1c are unlimited. For example, the first limiting part 1b and the second limiting part 1c can be arranged vertically, and the first limiting part 1b can be introduced into the second limiting part 1c from bottom to top or from top to bottom; the first limiting part 1b and the second limiting part 1c can be arranged horizontally, and the first limiting part 1b can be introduced into the second limiting part 1c from left to right or from right to left.

[0030] The conductive terminal 2 can be cylindrical or polygonal, and the wiring through hole 2a can be circular or polygonal. The conductive terminal 2 can be, but is not limited to, a copper terminal.

[0031] The dimensions of the wiring through hole 2a should meet the following condition: it should be able to accommodate a bare wire carrying a current of 200A.

[0032] The first connecting component 1d can be a countersunk hole or a hollow annular boss, and the number of countersunk holes or hollow annular bosses is unlimited; the fixing component 3 can be, but is not limited to, screws, and the number is unlimited; the second connecting component 2b can be, but is not limited to, threaded holes or through holes, and the number is unlimited.

[0033] In some embodiments, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a conductive terminal 2. The difference from the above embodiment is that the second connecting component 2b includes at least two first threaded holes, and the fixing component 3 includes at least two first screws. The first screws pass through the first connecting component 1d and are fastened to the first threaded holes, and are connected to the wiring through hole 2a.

[0034] Specifically, during wiring installation, one wire passes through the wiring through hole 2a and is fixed with the first screw; the other wire passes through the wiring through hole 2a and is fixed with the second screw.

[0035] The bottom of the first threaded hole is connected to the bottom of the wiring through hole 2a. That is, the depth of the first threaded hole should be machined to the bottom edge of the wiring through hole 2a, so that the first threaded hole can better contact and fix the wire.

[0036] The bottom of the first screw is concave, instead of flat. This concave end allows the wire to deform at different positions after being tightened and squeezed by the screw, resulting in a tighter fit and making it less likely to be pulled out.

[0037] In some embodiments, such as Figure 3 As shown, unlike the previous embodiment, the conductive terminal 2 is provided with a second threaded hole 2c between the first threaded holes. The diameter of the second threaded hole 2c is smaller than that of the first threaded hole. The fixing component 3 also includes a second screw, which passes through the first connecting component 1d and the second threaded hole 2c to fix the conductive terminal 2.

[0038] Specifically, the bottom of the second threaded hole 2c does not need to be connected to the bottom of the wiring through hole 2a. It is screwed onto the conductive terminal 2 and mainly serves as a limit to prevent the conductive terminal 2 from moving back and forth within the cavity 1a of the terminal box 1.

[0039] In some embodiments, such as Figure 4 As shown, Figure 4 This is a multi-view assembly diagram of a terminal box 1 and a cover 4. The difference from the previous embodiment is that the through-connection terminal also includes a cover 4; a slot 4a is provided on the top of the terminal box 1, and a buckle 1j is provided on the cover 4; and / or, a buckle 1j is provided on the top of the terminal box 1, and a slot 4a is provided on the cover 4; the buckle 1j and the slot 4a are engaged.

[0040] Specifically, the number and position of the buckle 1j and the slot 4a are not limited.

[0041] The dimensions of the cover 4 meet the following conditions: after assembly with the terminal box 1, the entire through-terminal meets the safety requirements of an electrical clearance of not less than 12.7 mm and a creepage distance of not less than 19.1 mm.

[0042] In some embodiments, unlike the foregoing embodiments, a base plate 1h is provided at the bottom of the third side wall and / or the bottom of the fourth side wall of the terminal box 1, and a fixing through hole 1i is provided on the base plate 1h.

[0043] Specifically, such as Figure 4 As shown, the base plate 1h can be folded towards the cover 4. When the base plate 1h is not needed, it can be folded away to save space. The base plate 1h is provided with a fixing through hole 1i. When it is necessary to fix the through terminal to the wall or other places, screws or pins can be used to pass through the fixing through hole 1i.

[0044] In some embodiments, the first connecting component 1d differs from the foregoing embodiments in that it includes an annular boss, which can increase the distance between the first screw and the outside world, so that the through-terminal meets the creepage distance of 19.1 mm.

[0045] In some embodiments, such as Figure 4 As shown, unlike the previous embodiment, the terminal box 1 has a first socket 1f at one end near the third side wall and a second socket 1g at one end near the fourth side wall. The baffle passes through the first socket 1f and the second socket 1g to restrict the position of the conductive terminal 2.

[0046] Specifically, the shapes of the first socket 1f and the second socket 1g are not limited, and the shape of the baffle matches the first socket 1f and the second socket 1g. The bottom of the baffle is provided with a structure that can accommodate the conductive terminal 2 through which it passes. The baffle passes through the first socket 1f and the second socket 1g, restricting the position of the conductive terminal 2, which can reduce the exposure of the conductive terminal 2 and improve the safety of the wiring terminals.

[0047] This utility model has the following technical effects:

[0048] By providing a first limiting part 1b on the first side wall of the terminal box 1 and a second limiting part 1c on the second side wall that cooperates with the first limiting part 1b, when multiple terminal boxes 1 need to be installed side by side, the first limiting part 1b and the second limiting part 1c can be connected without welding or screw fixing. The conductive terminal 2 has a wiring through hole 2a, and two wires can be directly passed through the wiring through hole 2a. The two wires can be fixed in the conductive terminal 2 by the fixing component 3 to achieve conductivity without welding or other installation steps, making installation convenient.

[0049] The bottom of the first screw is concave, instead of flat. This concave end allows the wire to deform at different positions after being tightened and squeezed by the screw, resulting in a tighter fit and making it less likely to be pulled out.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
