Description

Technical Field

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

[0002] Terminal blocks are accessories used to achieve electrical connections. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually rising. As the electronics industry develops, the application range of terminal blocks is expanding, and the types of terminal blocks are also increasing.

[0003] Application number CN201521123032.7 discloses a novel meter terminal block with a metal terminal block having a wire hole. The metal terminal block has a protrusion perpendicular to the wire hole at its upper part, with a threaded hole through the wire hole at its center. A clamping screw is located inside the threaded hole, and the bottom of the threaded hole is a smooth hole. A wire clamping block is located inside the wire hole, having an arc-shaped clamping portion and a guide post extending into the smooth hole. An elastic support leg is located in the middle of the wire clamping block, supporting the wire hole. This design ensures tight contact and clamping between the terminal block and the wire, preventing terminal burnout due to poor contact, guaranteeing the normal operation of household appliances, extending contact life, and reducing maintenance costs.

[0004] However, the elastic support leg of the device has an arc-shaped structure, which is prone to metal fatigue, weakening of elasticity, or even breakage under long-term pressure. In addition, the terminal block is an integral structure, which makes it inconvenient to disassemble and replace the internal pressure block and guide post. Therefore, a new type of meter terminal block is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a meter terminal block.

[0006] The technical solution adopted by this utility model to solve its technical problem is an electric meter terminal block, including a terminal block body. A light hole is opened at the center of the top of the terminal block body for inserting a guide post. A spring cavity is also opened at the top of the terminal block body. There are two spring cavities, which are located on both sides of the light hole and communicate with the interior of the light hole. A spring is provided at the bottom of the inner part of the spring cavity for inserting a connecting rod. The bottom end of the guide post is fixedly connected to the top end of the pressure block. The top end of the pressure block is provided with a first threaded groove, which is adapted to the thread at the bottom end of the guide post.

[0007] By adopting the above technical solution, the spring setting can ensure smooth movement and automatic reset of the pressure block, and the spring has better elasticity and is less prone to breakage. The detachable mode of the terminal body and the protrusion makes it easier to disassemble and replace the guide post, pressure block and spring, thus improving the service life of the terminal.

[0008] Specifically, a ball bearing is embedded in the outer side of the guide post, and multiple balls bearings are provided, with the multiple balls bearings contacting the inner side of the optical aperture.

[0009] By adopting the above technical solution, the ball bearings reduce the frictional resistance between the guide post and the inner wall of the aperture. When the threaded post drives the guide post to move up and down, the ball bearings roll and cooperate to make its movement smoother, avoiding jamming or wear caused by friction.

[0010] Specifically, a protrusion is installed at the top of the terminal block body, and connecting blocks are fixedly connected to the lower parts of the opposite sides of the protrusion. A bolt is installed through the inside of the connecting block, and a threaded hole is opened at the top of the terminal block body for the bolt to be screwed in.

[0011] By adopting the above technical solution, the protrusion covers the top of the light hole, and the bolt passes through the connecting block and is screwed into the threaded hole at the top of the terminal body to fix the protrusion to the terminal body and ensure the stability of the overall structure.

[0012] Specifically, a second threaded groove is provided at the center of the protrusion. The second threaded groove is threaded and adapted to the threaded post. The interior of the second threaded groove is connected to the interior of the optical hole.

[0013] By adopting the above technical solution, after the threaded column is screwed into the second threaded groove, its bottom end extends into the optical hole and contacts the top of the guide column. By rotating the threaded column, its downward pressure can be precisely adjusted, pushing the guide column and the wire pressing block to move vertically along the optical hole, thereby achieving the pressing or releasing of the wire.

[0014] Specifically, a wiring hole is provided on one side of the terminal block body, which is used for inserting wires.

[0015] By adopting the above technical solution, the wire is inserted horizontally into the body of the terminal block through the wiring hole, and its end extends to the bottom of the wire pressing block.

[0016] Specifically, the pressure block is located inside the upper part of the wiring hole, and the interior of the wiring hole is connected to the interior of the optical hole.

[0017] By adopting the above technical solution, when the threaded column drives the guide column to move downward, the pressure block moves downward accordingly and presses the wire. The design of connecting the wiring hole and the optical hole makes the movement path of the pressure block orthogonal to the insertion direction of the wire, forming a vertical pressing structure, ensuring uniform distribution of the pressing force and reliable contact.

[0018] The beneficial effects of this utility model are:

[0019] The meter terminal block described in this utility model features a spring that ensures smooth movement and automatic reset of the pressure block. The spring also has better elasticity and is less prone to breakage. The detachable design of the terminal block body and the protrusion makes it easier to disassemble and replace the guide post, pressure block, and spring, thus improving the service life of the terminal block.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As one embodiment of this utility model, such as Figures 1-3 As shown, the present invention discloses a meter terminal block, including a terminal block body 11. A light hole 15 is provided at the center of the top of the terminal block body 11 for inserting a guide post 9. A spring cavity 8 is also provided at the top of the terminal block body 11. There are two spring cavities 8, which are located on both sides of the light hole 15 and communicate with the interior of the light hole 15. A spring 4 is provided at the bottom of the inner part of the spring cavity 8 for inserting a connecting rod 1. The bottom end of the guide post 9 is fixedly connected to the top end of the pressure block 10. The top end of the pressure block 10 is provided with a first threaded groove 14, which is threadedly adapted to the bottom end of the guide post 9.

[0027] When in use, after the guide post 9 is vertically inserted into the light hole 15, the connecting rod 1 is simultaneously inserted into the spring cavity 8. The top of the spring 4 abuts against the bottom of the connecting rod 1 to provide pre-tightening force. When the pressure block 10 is threadedly connected to the bottom of the guide post 9 through the first threaded groove 14, the connecting rod 1 cannot rotate due to the restriction of the spring cavity 8. The thread is tightened by rotating the pressure block 10, thereby realizing the linkage assembly of the guide post 9 and the pressure block 10.

[0028] It should be noted that if the wire pressing block 10 is not oriented correctly when tightening the connection between it and the guide post 9, it can be disassembled, tightened in a different direction, until the wire pressing block 10 is oriented correctly. Figure 1 As shown, the wire 12 can be easily pressed and fixed.

[0029] The present invention also includes that a ball bearing 13 is inlaid on the outer side of the guide post 9, and multiple balls bearing 13 are provided, with multiple balls bearing 13 in contact with the inner side of the light hole 15.

[0030] During use, the ball bearing 13 reduces the frictional resistance between the guide post 9 and the inner wall of the aperture 15. When the threaded post 6 drives the guide post 9 to move up and down, the ball bearing 13 rolls to make its movement smoother, avoiding jamming or wear caused by friction.

[0031] The present invention also includes a protrusion 7 installed at the top of the terminal block body 11, a connecting block 3 fixedly connected to the lower part of the opposite sides of the protrusion 7, a bolt 2 being installed through the interior of the connecting block 3, and a threaded hole being provided at the top of the terminal block body 11 for the bolt 2 to be screwed in.

[0032] In use, the protrusion 7 covers the top of the light hole 15, and the bolt 2 passes through the connecting block 3 and is screwed into the threaded hole at the top of the terminal body 11 to fix the protrusion 7 to the terminal body 11, ensuring the stability of the overall structure.

[0033] The present invention also includes a second threaded groove 16 provided at the center of the protrusion 7, the second threaded groove 16 being threadedly adapted to the threaded post 6, and the interior of the second threaded groove 16 being connected to the interior of the light hole 15.

[0034] When in use, after the threaded post 6 is screwed into the second threaded groove 16, its bottom end extends into the light hole 15 and contacts the top of the guide post 9. By rotating the threaded post 6, its downward pressure can be precisely adjusted, pushing the guide post 9 and the wire pressing block 10 to move vertically along the light hole 15, thereby pressing or releasing the wire 12.

[0035] The present invention also includes a wiring hole 5 on one side of the terminal block body 11, the wiring hole 5 being used for inserting and installing the wire 12.

[0036] In use, the wire 12 is inserted laterally into the body of the terminal block 11 through the wiring hole 5, with its end extending below the wire clamping block 10.

[0037] The present invention also includes that the wire pressing block 10 is disposed in the upper part of the wiring hole 5, and the interior of the wiring hole 5 is connected to the interior of the light hole 15.

[0038] In use, when the threaded post 6 drives the guide post 9 to move downward, the wire pressing block 10 moves downward accordingly and presses the wire 12. The connection design between the wiring hole 5 and the light hole 15 makes the movement path of the wire pressing block 10 orthogonal to the insertion direction of the wire 12, forming a vertical pressing structure, ensuring that the pressing force is evenly distributed and the contact is reliable.

[0039] In use, the guide post 9 is first vertically inserted into the light hole 15, allowing the connecting rod 1 to also be inserted into the spring cavity 8, with the top of the spring 4 resting against the bottom of the connecting rod 1. Then, the wire clamping block 10 is inserted through the wiring hole 5, and the first threaded groove 14 at the top of the wire clamping block 10 is connected to the thread at the bottom of the guide post 9. Because the connecting rod 1 is stuck in the spring cavity 8, preventing the guide post 9 from rotating, the wire clamping block 10 needs to be rotated for connection. Finally, the protrusion 7 is installed on the top of the wiring post body 11. Align the second threaded groove 16 with the light hole 15, then screw the bolt 2 from the inside of the connecting block 3 into the inside of the terminal body 11, so that the protrusion 7 and the terminal body 11 can be fixedly connected. Finally, screw the threaded post 6 into the second threaded groove 16 to complete the installation. The wire 12 can be inserted into the terminal hole 5. By turning the threaded post 6, the threaded post 6 can be moved downward. The downward movement of the threaded post 6 can push the guide post 9 downward, thereby driving the wire pressing block 10 to press onto the wire 12, and pressing and fixing the wire 12.
