Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and more specifically, to a multi-interface connection terminal block. Background Technology

[0002] Terminal blocks are critical electrical connection components, indispensable in various circuit systems. They reliably connect different wires, cables, and electrical equipment conductors, establishing complete electrical circuits. Standardized wiring facilitates installation and maintenance, improving operational efficiency. Their excellent electrical performance reduces resistance and heat generation, ensuring safe operation.

[0003] Currently, multi-interface terminal blocks are mainly rectangular arrays. The more interfaces there are, the longer the block becomes. These long arrays of terminal blocks take up a lot of space during installation, especially in distribution boxes with limited installation space, reducing the number of electrical connections that can be made. Therefore, we propose a multi-interface connection terminal block. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a multi-interface connection terminal block to solve the problem that the current long row of terminal blocks occupies a lot of space when installed, especially in some distribution boxes with small installation space, and to reduce the number of electrical equipment connections.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-interface connection terminal block, including a mounting mechanism and a terminal block mechanism mounted on the mounting mechanism. The mounting mechanism includes a mounting frame with mounting holes. The mounting frame is U-shaped, and a mounting post is provided inside the U-shaped opening of the mounting frame. The terminal block mechanism includes several terminal boxes that are rotatably connected to each other. Mounting plates are symmetrically arranged on the first and last terminal boxes. The terminal boxes are mounted on the mounting posts. The terminal block mechanism and the mounting posts form a cylindrical shape.

[0006] Preferably, the mounting plate has a fixing hole, and the mounting post has a threaded hole corresponding to the fixing hole, and screws are installed in the fixing hole and the threaded hole.

[0007] Preferably, the terminal box has symmetrically arranged contact pieces, which are U-shaped and have conductive pieces between them. The terminal box has wiring holes at its upper and lower ends.

[0008] Preferably, the front end of the terminal box is symmetrically provided with receiving grooves corresponding to the contact plates, a clamping block is rotatably installed in the receiving groove, the rear end of the clamping block is provided with a semi-circular groove, and the front end of the clamping block is provided with a pull ring.

[0009] Preferably, a fixing plate is symmetrically arranged at the front end of the terminal box, a circular groove is provided at the side end of the fixing plate, a spring is provided in the circular groove, and a limit plate is installed at the end of the spring.

[0010] Preferably, the limiting plate includes a positioning part and a guiding part. The positioning part is L-shaped and the guiding part is arc-shaped. Positioning protrusions are provided on both sides of the front end of the pressing block, and the positioning protrusions are located between the positioning parts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model designs a terminal box structure. The terminal block mechanism is composed of several terminal boxes that are rotatably connected to each other. When in use, the terminal blocks can be arranged in a cylindrical shape. Compared with the traditional long row of terminal blocks, more wires can be connected in a limited space. This can effectively reduce the space occupied in the distribution box and other equipment, improve the space utilization rate, and solve the problem that the current long row of terminal blocks occupies too much space when installed, especially in some distribution boxes with small installation space, thus reducing the number of electrical equipment connections.

[0013] 2. This utility model also features a clamping block structure. When the wire is inserted into the wiring hole, rotating the clamping block can press the wire firmly. The spring-loaded limiting plate can fix the clamping block in place. Compared to fixing the wire with screws, fixing the wire with the clamping block is simpler and faster, improving the efficiency of wire installation and connection. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a multi-interface connection terminal block, including a mounting mechanism 100 and a terminal block mechanism 200 mounted on the mounting mechanism 100. The mounting mechanism 100 includes a mounting frame 101 with mounting holes 102. The mounting frame 101 is U-shaped, and a mounting post 103 is provided inside the U-shaped opening of the mounting frame 101. The terminal block mechanism 200 includes several terminal boxes 201 that are rotatably connected to each other. Mounting plates 202 are symmetrically arranged on the first and last terminal boxes 201. The terminal boxes 201 are mounted on the mounting posts 103. The terminal block mechanism 200 and the mounting posts 103 form a cylindrical shape. This utility model's terminal block has two states: a long row shape and a cylindrical shape. The cylindrical terminal block can connect more wires in a limited space, effectively reducing the space occupied in equipment such as distribution boxes and improving space utilization.

[0022] Specifically, the mounting plate 202 has fixing holes, and the mounting post 103 has threaded holes corresponding to the fixing holes. Screws are installed in the fixing holes and threaded holes. The mounting plate 202 and the mounting holes allow this invention to be installed in equipment such as distribution boxes.

[0023] Furthermore, symmetrically arranged contact pieces 205 are provided inside the terminal box 201. The contact pieces 205 are U-shaped, and conductive pieces 206 are arranged between the contact pieces 205. Wiring holes 203 are provided at the upper and lower ends of the terminal box 201. After the wire is inserted through the wiring hole 203, it can contact the contact piece 205, and the circuit can be connected under the action of the conductive piece 206.

[0024] It is worth noting that the terminal box 201 has symmetrically arranged receiving grooves 204 at its front end, corresponding to the contact piece 205. A clamping block 210 is rotatably installed in the receiving groove 204. The rear end of the clamping block 210 has a semi-circular groove, and the front end of the clamping block 210 is equipped with a pull ring 212. Pulling the pull ring 212 at the front end of the clamping block 210 causes the clamping block 210 to rotate. When the clamping block 210 rotates into the receiving groove 204, the semi-circular groove at the rear end of the clamping block 210 can clamp the wire onto the contact piece 205, achieving a stable electrical connection.

[0025] It is worth mentioning that the terminal box 201 has symmetrically arranged fixing plates 207 at its front end. The side end of the fixing plate 207 has a circular groove, and a spring 208 is arranged in the circular groove. The end of the spring 208 is equipped with a limiting plate 209. The positioning protrusion 211 can be squeezed into the space between the limiting plates 209 during the rotation of the clamping block 210, and the clamping block 210 can be fixed by the limiting plates 209.

[0026] It is worth noting that the limiting plate 209 includes a positioning part 2091 and a guide part 2092. The positioning part 2091 is L-shaped, and the guide part 2092 is arc-shaped. Positioning protrusions 211 are provided on both sides of the front end of the clamping block 210, and the positioning protrusions 211 are located between the positioning parts 2091. The wide angle between the guide parts 2092 can guide the positioning protrusions 211. When the positioning protrusions 211 are located in the positioning part 2091, the clamping block 210 can be fixed by the reaction force of the spring 208 to prevent the clamping block 210 from rotating on its own.

[0027] Working Principle: This embodiment provides a multi-interface connection terminal block. In use, the terminal block mechanism 200 can be installed in a long row within a distribution box or other equipment via a mounting plate. Alternatively, the terminal block mechanism 200 can be installed around the mounting post 103, making it cylindrical. Then, the device is installed in the distribution box via the mounting bracket 101. This not only allows for the connection of more wires but also effectively saves installation space within the distribution box. After installation in the distribution box, the wire is inserted through the wiring hole 203 at the top or bottom of the terminal box 201. The conductive end of the wire can be disconnected from the contact piece 205, thereby connecting the terminal block. The circuit is connected, and then the pull ring 212 at the front end of the clamping block 210 is pulled to make the clamping block 210 rotate. When the clamping block 210 rotates into the receiving groove 204, the semi-circular groove at the rear end of the clamping block 210 can press the wire onto the contact piece 205 to achieve a stable electrical connection. Secondly, the positioning protrusion 211 can be squeezed into the space between the limiting plates 209 during the rotation of the clamping block 210. The wide angle of the guide part 2092 can guide the positioning protrusion 211. When the positioning protrusion 211 is located in the positioning part 2091, the clamping block 210 can be fixed under the reaction force of the spring 208 to prevent the clamping block 210 from rotating on its own.

[0028] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
