Summary of the Invention

[0003] In response, this utility model provides a terminal block that is easy to assemble.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a terminal block, including a housing and a wiring assembly. The side of the housing is provided with an inlet hole corresponding to the wiring assembly. The wiring assembly includes a wiring frame that can be movably disposed within the housing and a wiring screw screwed to the upper end of the wiring frame. The upper end of the housing is provided with an opening corresponding to the head of the wiring screw. An annular flange is provided on the outer periphery of the head of the wiring screw. The housing includes two half-shells that are fitted together. The opening is located at the mating point of the two half-shells. Limiting grooves are formed on the inner walls of the two half-shells at corresponding positions at the opening. The limiting grooves on the two half-shells are joined together to form a limiting cavity. The annular flange is confined within the limiting cavity to restrict the vertical movement of the wiring screw.

[0006] In some embodiments, a groove is provided on the inner wall of the semi-shell at a position corresponding to the wiring frame, and the side portion of the wiring frame is limited within the groove, wherein the groove is provided along the vertical direction.

[0007] In some embodiments, there are two wiring assemblies, which are respectively located at opposite ends within the housing and connected by a copper sheet. The copper sheet is positioned within the housing, and the wiring frames in the two wiring assemblies are respectively sleeved on both ends of the copper sheet.

[0008] In some embodiments, one of the two shell halves is provided with a buckle, and the other half is provided with a corresponding buckle hole. The buckle and the buckle hole cooperate to connect the two shell halves, and the direction in which the buckle and the buckle hole engage is the same as the direction in which the two shell halves align.

[0009] In some embodiments, the copper sheet has a positioning part in the middle, and the half shell is provided with a slot that engages with the positioning part.

[0010] In some embodiments, the positioning part is bent into an n-shaped structure, and a locking block that engages with the n-shaped structure is provided on the lower side of the slot.

[0011] The positive effects of this utility model are: the electrical terminal structure of this utility model is reasonably designed, easy to assemble, and has good practicality; when wiring, the screwdriver is inserted through the opening and connected to the head of the wiring screw, and then the wiring frame is moved up and down by turning the wiring screw, thereby clamping and loosening the wire; since the housing adopts the method of two half-shells joining together, the opening is set at the joining point of the two half-shells, and the limiting groove is set, which facilitates the quick and reliable installation of the wiring assembly into the housing.

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] The terminal block structure in this embodiment of the utility model is as follows: Figures 1 to 6 As shown, it includes a housing 1 and a wiring assembly 2. The housing 1 has a wire inlet hole 11 on its side corresponding to the wiring assembly 2. A wire extends into the housing 1 through the wire inlet hole 11 and connects to the wiring assembly 2. The wiring assembly 2 includes a wiring frame 21 that can be movably mounted inside the housing 1 and a wiring screw 22 screwed to the upper end of the wiring frame 21. The upper end of the housing 1 has an opening 12 corresponding to the head of the wiring screw 22. An annular flange 221 is provided on the outer periphery of the head of the wiring screw 22. The housing 1 includes two half-shells 13 that are fitted together. The opening 12 is located at the mating point of the two half-shells 13. Limit grooves 14 are formed on the inner walls of the two half-shells 13 at corresponding positions of the opening 12. The limiting groove 14 is assembled to form a limiting cavity. The annular flange 221 is limited within the limiting cavity to restrict the up and down movement of the wiring screw 22. Thus, when the wiring screw 22 is turned, it will drive the wiring frame 21 to move up and down. When wiring, the screwdriver is inserted through the opening 12 and connected to the head of the wiring screw 22. Then, the wiring frame 21 is moved up and down by turning the wiring screw 22, thereby clamping and loosening the wire. Since the housing 1 adopts the method of two half-shells 13 being joined together, the opening 12 is set at the joining point of the two half-shells 13, and the limiting groove 14 is set to facilitate the quick and reliable installation of the wiring assembly 2 into the housing 1. There is no need to set a partition to position the wiring screw 22, which makes the assembly convenient and has good practicality.

[0023] like Figure 2 and Figure 3 As shown, a groove 15 is provided on the inner wall of the half shell 13 at a position corresponding to the wiring frame 21. The side of the wiring frame 21 is limited within the groove 15. The groove 15 is arranged in the vertical direction. The groove 15 can effectively guide the installation limit and movement of the wiring frame 21, and can prevent the wiring frame from shifting during assembly or use.

[0024] like Figure 3As shown, there are two wiring components 2, which are respectively located at opposite ends inside the housing 1 and connected by a copper sheet 23. The copper sheet 23 is positioned inside the housing 1, and the wiring frames 21 in the two wiring components 2 are respectively sleeved on both ends of the copper sheet 23. In practical applications, the user can insert the wire to be connected into the wiring frame 21 through the wire inlet hole 11, and then tighten the wiring screw 22 to move the wiring frame 21 in the up and down direction, thereby pressing the wire between the copper sheet 23 and the wiring frame 21. The two wiring components 2 are electrically connected by the copper sheet 23. The wiring method of clamping the wire with the wiring frame 21 and the copper sheet 23 will not damage the wire.

[0025] Combination Figure 2 , Figure 3 and Figure 5 As shown, one of the two half-shells 13 is provided with a buckle 16, and the other is provided with a corresponding buckle hole 17. The buckle 16 and the buckle hole 17 cooperate to connect the two half-shells 13, and the direction in which the buckle 16 and the buckle hole 17 engage is the same as the direction in which the two left half-shells 13 align. In this way, during the alignment of the two half-shells 13, the buckle 16 and the buckle hole 17 engage to fix the two half-shells 13 together, ensuring the convenience and stability of assembly. Optionally, two to four buckles 16 are provided, and the number of corresponding buckle holes 17 is also two to four.

[0026] like Figure 3 As shown, the copper sheet 23 has a positioning part 231 in the middle, and the half shell 13 is provided with a slot 18 that engages with the positioning part 231. The copper sheet 23 can be reliably positioned inside the shell 1 by engaging the positioning part 231 with the slot 18. In order to further enhance the positioning effect of the copper sheet 23, the positioning part 231 can be bent into an n-shaped structure, and a locking block 19 that engages with the n-shaped structure is provided on the lower side of the slot 18. The positioning of the copper sheet 23 can be enhanced by the cooperation between the positioning part and the locking block 19.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
