Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to a terminal block. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections and are widely used in industrial, electronic, and electrical fields. They are primarily used to facilitate the connection between wires, improving the reliability and convenience of the connection. Terminal blocks are typically made of a metal sheet wrapped in insulating material, with holes or clamping devices at both ends to secure and connect wires, facilitating maintenance and replacement. To connect a wire, insert it into the hole of the terminal block and tighten the screw using a tool to clamp and secure the wire between the metal sheet and the terminal block.

[0003] Regarding the above technical conditions, there is also a drawback: the wires need to be locked and fixed to the terminals using tools, but when there is insufficient space to use tools, it is inconvenient to fix the wires to the terminals.

[0004] Based on this, the present invention designs a wiring terminal to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a terminal block to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a terminal block, comprising a housing and a metal sheet, wherein the housing has a plug hole, the metal sheet is fixedly disposed in the plug hole, the housing has a rotating hole, two rotating holes are provided on the housing, the rotating holes communicate with the plug hole, a threaded rod is rotatably disposed in the rotating hole, one end of the threaded rod is fixedly connected to a rotating block, the other end of the threaded rod is located in the plug hole, a locking block is disposed in the plug hole, the outer side wall of the locking block abuts against the inner side wall of the plug hole, the locking block has a threaded hole, and one end of the threaded rod located in the plug hole is threadedly connected to the threaded hole.

[0007] Preferably, a first anti-slip stripe is fixedly provided on the side of the locking block near the metal sheet. Multiple first anti-slip stripes are provided on the locking block, and the first anti-slip stripe is a vertical stripe.

[0008] Preferably, a second anti-slip stripe is fixedly provided on the side of the metal sheet near the locking block. Multiple second anti-slip stripes are provided on the metal sheet, and the second anti-slip stripe is a horizontal stripe.

[0009] Preferably, the rotating block has a drive groove at the end away from the threaded rod.

[0010] Preferably, a guide strip is fixedly provided in the insertion hole, and a guide groove adapted to the guide strip is provided on the outer side wall of the locking block, and the guide strip is inserted into the guide groove.

[0011] Preferably, auxiliary stripes are fixedly provided on the outer wall of the rotating block, and multiple auxiliary stripes are provided on the rotating block.

[0012] In summary, this application has the following beneficial technical effects: When the space available for the terminal block is insufficient to use tools, by directly contacting the rotating block by hand and rotating it counterclockwise, the locking block moves upward in the insertion hole with the cooperation of the threaded rod and the threaded hole, increasing the space between the metal plate and the locking block. One end of the wire is inserted into the insertion hole, positioned between the metal plate and the locking block. Then, by rotating the rotating block clockwise by hand, the locking block moves downward in the insertion hole, clamping and fixing the wire between the metal plate and the locking block. This achieves the effect of conveniently fixing the wire to the terminal block without using tools. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] A terminal block includes a housing 6 and a metal plate 4. The housing 6 has a insertion hole, and the metal plate 4 is fixedly disposed in the insertion hole. The housing 6 also has two rotating holes 13, which communicate with the insertion hole. A threaded rod 7 is rotatably mounted on each rotating hole 13. One end of the threaded rod 7 is fixedly connected to a rotating block 3, and the other end of the threaded rod 7 is located in the insertion hole.

[0019] A locking block 8 is provided in the insertion hole. The outer wall of the locking block 8 abuts against the inner wall of the insertion hole. A threaded hole 11 is provided on the locking block 8. One end of the threaded rod 7 located in the insertion hole is threaded into the threaded hole 11. By rotating the threaded rod 7 by rotating the rotating block 3, the locking block 8 can move up and down in the insertion hole under the cooperation of the threaded rod 7 and the threaded hole 11.

[0020] When in use, insert one end of the wire into the plug hole, so that the wire is between the metal plate 4 and the locking block 8. Hold the rotating block 3 with your hand and rotate the rotating block 3. The threaded rod 7 rotates clockwise. The locking block 8 moves down in the plug hole under the cooperation of the threaded rod 7 and the threaded hole 11. The wire is clamped and fixed between the locking block 8 and the metal plate 4.

[0021] A drive groove 1 is provided at the end of the rotating block 3 away from the threaded rod 7. The drive groove 1 can be a hexagonal groove, a cross groove, a slotted groove, etc. In this embodiment, a hexagonal groove is used as an example. Through the drive groove 1, the rotating block 3 can be easily rotated using a wrench or screwdriver, which facilitates the up-and-down movement of the locking block 8 in the insertion hole. When there is insufficient operating space to use tools, the rotating block 3 can also be directly rotated by hand to drive the locking block 8, making it easy to fix the wire to the terminal block.

[0022] A first anti-slip stripe 10 is fixedly provided on the side of the locking block 8 near the metal sheet 4. Multiple first anti-slip stripes 10 are provided on the locking block 8, and these stripes are vertical. A second anti-slip stripe 5 is fixedly provided on the side of the metal sheet 4 near the locking block 8. Multiple second anti-slip stripes 5 are provided on the metal sheet 4, and these stripes are horizontal. The first and second anti-slip stripes 10 and 5 serve to prevent slippage. By setting the anti-slip stripes in different directions, the anti-slip stripes can exert different directions of support force on the wire, making the wire less likely to fall off.

[0023] A guide strip 9 is fixedly installed in the insertion hole, and a guide groove 12 adapted to the guide strip 9 is opened on the outer side wall of the locking block 8. The guide strip 9 is inserted into the guide groove 12. The guide strip 9 and the guide groove 12 play a guiding and stabilizing role, so that the locking block 8 is not prone to displacement or shaking when moving up and down in the insertion hole.

[0024] Auxiliary stripes 2 are fixedly provided on the outer wall of the rotating block 3, and multiple auxiliary stripes 2 are provided on the rotating block 3. The auxiliary stripes 2 serve to increase the contact friction between the rotating block 3 and the hand, making it easier for the hand to rotate the rotating block 3.

[0025] The implementation principle of this embodiment is as follows: When the space available for the terminal block is insufficient to use tools, the rotating block 3 is directly contacted by hand and rotated counterclockwise. With the cooperation of the threaded rod 7 and the threaded hole 11, the locking block 8 moves upward in the insertion hole, increasing the space between the metal plate 4 and the locking block 8. One end of the wire is inserted into the insertion hole, positioning it between the metal plate 4 and the locking block 8. Then, the rotating block 3 is rotated clockwise by hand, causing the locking block 8 to move downward in the insertion hole. The wire is clamped and fixed between the metal plate 4 and the locking block 8, achieving the effect of conveniently fixing the wire to the terminal block without using tools.
