Description

Technical Field

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

[0002] Through-wall terminal blocks are accessories used to achieve electrical connections. They can be installed side by side on panels with thicknesses ranging from 1mm to 10mm. They can automatically compensate for and adjust the distance of the panel thickness to form terminal blocks with any number of poles. Furthermore, they can use isolation plates to increase air gaps and creepage distances.

[0003] Patent CN216389813U discloses a through-wall terminal block, which includes a pin holder, a retaining sleeve, and a socket. Both the pin holder and the socket have wire insertion ports on their opposite ends. The pin holder and the socket also have slots and plugs on their opposite ends, with the plug being inserted into the slot. The device first fixes the retaining sleeve to the wall, then connects both sides of the pin holder to the retaining sleeve via a snap-fit ​​mechanism. Finally, the plug of the socket is inserted into the slot of the pin holder through the retaining sleeve. Installation is convenient. Disassembly is simple: pull out the socket, release the snap-fit ​​mechanism, and remove the pin holder.

[0004] However, the device lacks a connection mechanism between the socket and the pin socket. The socket is only connected by inserting a plug into the slot in the pin socket and then fixing the socket with bolts. If the bolts at the connection point rust after long-term use, it becomes difficult to disassemble the terminal block. Therefore, a through-wall terminal block is proposed to solve the problem of the existing terminal blocks being difficult to install and disassemble. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a through-wall terminal block, which solves the aforementioned problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a through-wall terminal block, including a retaining sleeve, a hole seat on one side of the retaining sleeve, a pin seat on the other side of the retaining sleeve, a fixing seat fixedly connected to both ends of the hole seat, a limit mechanism provided at one end of the fixing seat, a connecting frame fixedly connected to the outer ring of one side of the pin seat, an installation hole opened on one side of the connecting frame, a first slot symmetrically opened on one side of the connecting frame, a second slot symmetrically opened on one side of the retaining sleeve, a moving groove opened at one end of the fixing seat, a moving block and a spring provided in the inner cavity of the moving groove, an L-shaped retaining plate fixedly connected to one side of the moving block, a chamfered edge provided at one end of the L-shaped retaining plate, and a guide groove opened on the side of the fixing seat facing the retaining sleeve.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-4 A through-wall terminal block includes a sleeve 1, a hole seat 2 on one side of the sleeve 1, a pin seat 3 on the other side of the sleeve 1, a fixing seat 4 fixedly connected to both ends of the hole seat 2, a limit mechanism 5 at one end of the fixing seat 4, a connecting frame 6 fixedly connected to the outer ring of one side of the pin seat 3, an installation hole 7 on one side of the connecting frame 6, a first slot 8 symmetrically opened on one side of the connecting frame 6, a second slot 9 symmetrically opened on one side of the sleeve 1, a moving groove 10 opened at one end of the fixing seat 4, a moving block 11 and a spring 12 arranged in the inner cavity of the moving groove 10, an L-shaped plate 13 fixedly connected to one side of the moving block 11, a chamfer 14 provided at one end boundary of the L-shaped plate 13, and a guide groove 15 opened on the side of the fixing seat 4 facing the sleeve 1.

[0025] Furthermore, both ends of the spring 12 are fixedly connected to the moving block 11 of the moving groove 10, and the moving groove 10 and the moving block 11 are slidably connected.

[0026] Furthermore, spring 12 is initially in a compressed state.

[0027] Furthermore, the guide groove 15 and the moving groove 10 are interconnected, and the L-shaped card plate 13 passes through the moving block 11 and the two are slidably connected.

[0028] Furthermore, the limiting mechanism 5 includes a limiting bearing 501 disposed at one end of the fixed seat 4. The outer ring of the limiting bearing 501 is fixedly connected to the fixed seat 4, and the inner ring of the limiting bearing 501 is fixedly connected to a rotating shaft 502.

[0029] Furthermore, a limiting arc block 503 is fixedly connected to the outer ring of the rotating shaft 502. When the limiting arc block 503 rotates to the bottom, it just contacts the moving block 11. After the hole seat 2 and the pin seat 3 are installed on the sleeve 1 through the cooperation of the L-shaped card plate 13, the first card slot 8, the second card slot 9, the spring 12 and other structures, the limiting arc block 503 rotates to one end of the moving block 11 under the action of the weight of the limiting bearing 501, the rotating shaft 502 and the limiting arc block 503 itself, thus blocking the moving block 11 from one end and preventing the terminal from falling off due to accidental contact. When it is necessary to disassemble the hole seat 2 and the pin seat 3, the limiting arc block 503 is rotated 180 degrees and the moving block 11 in the fixed seats 4 at both ends is pressed to disassemble the terminal, thereby improving the firmness of the terminal after installation.

[0030] Furthermore, a mating groove 16 is provided through one side of the fixing seat 4, and a mating block 17 is symmetrically and fixedly connected to one side of the sleeve 1. The hole seat 2 is installed on the sleeve 1. Through the cooperation of the mating groove 16 on the fixing seat 4 and the mating block 17 on the sleeve 1, the hole seat 2 can be initially limited, which facilitates the subsequent connection and installation of the needle seat 3 and the hole seat 2 on the sleeve 1.

[0031] Working principle: When using this through-wall terminal block, after installing the sleeve 1 in the desired position through the mounting hole 7, insert the hole seat 2 into the sleeve 1. During this process, with the help of the chamfer 14, the L-shaped retaining plate 13 moves towards the center and passes through the second retaining groove 9 for initial installation. Then, the pin seat 3 is inserted into the hole seat 2. During this process, with the help of the spring force 12, the pin seat 3 is connected to the hole seat 2 under the action of the first retaining groove 8 on the connecting frame 6, thus completing the installation of the terminal block. Conversely, by moving the L-shaped retaining plate 13 towards the center through the moving block 11 in the moving groove 10, the limiting position of the hole seat 2 and the pin seat 3 can be released, and it can be removed from the sleeve 1. This solves the problem of the inconvenience of existing terminal blocks. The installation and disassembly process involves several steps. After the hole seat 2 and pin seat 3 are installed on the sleeve 1 using the L-shaped card plate 13, the first card slot 8, the second card slot 9, and the spring 12, the limiting arc block 503 rotates to one end of the moving block 11 under the weight of the limiting bearing 501, the rotating shaft 502, and the limiting arc block 503. This blocks the moving block 11 from one end, preventing accidental contact that could cause the terminal to fall off. When it is necessary to disassemble the hole seat 2 and pin seat 3, the limiting arc block 503 is rotated 180 degrees, and then the moving block 11 inside the fixing seats 4 at both ends is pressed to disassemble the terminal, thus improving the stability of the terminal after installation.
