Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically to a detachable and recyclable terminal block structure. Background Technology

[0002] A terminal block is a standardized interface device used to achieve electrical connections. Its core function is to establish a stable electrical path between wires or between a wire and a device through a metal conductor encapsulated in insulating material, while providing mechanical fixation and electrical isolation. Its typical structure is a metal plate with holes at both ends, which secures the wires with screws, enabling convenient connection and disconnection and avoiding welding or tangling operations. This design is widely used in power, electronics, communications and other fields.

[0003] Traditional terminal blocks are typically made by injection molding of metal and plastic in one piece. This process involves embedding the metal conductive parts into a mold and then encapsulating them with plastic through high temperature and pressure, forming a tight bond between the insulating shell and the conductive parts. This method offers advantages such as high structural strength, vibration resistance, impact resistance, and good sealing. The production cost of this process is relatively low, making it suitable for large-scale automated production. It is mainly used in automotive connectors, industrial equipment terminal blocks, and other applications.

[0004] However, this traditional design presents significant recycling challenges after it is scrapped. Because the metal and plastic are tightly bonded by chemical bonds or mechanical interlocking, high-temperature heating is required during recycling to soften the plastic in order to separate the metal and plastic parts. The material separation process is quite difficult, increasing recycling costs and complexity. Utility Model Content

[0005] The purpose of this invention is to provide a detachable and recyclable terminal block structure to solve the problems mentioned in the background art.

A set of fixing plates is fixedly connected to both sides of the terminal mounting shell, and the two sets of fixing plates are symmetrically arranged. Each set of fixing plates consists of two plates. A mounting hole is provided through the upper surface of each fixing plate. A guide groove is fixedly connected to the upper surface of the terminal mounting shell. A guide plate is slidably connected to the inner wall of the guide groove. The side of the guide plate away from the guide groove is fixedly connected to the outer wall of the terminal block body. A fixing component is fixedly connected to the bottom of the terminal block body.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1-5 The present invention provides the following two preferred embodiments: Example 1: A detachable and recyclable terminal block structure includes a terminal mounting shell 1 and a terminal block body 3. A set of fixing plates 2 are fixedly connected to both sides of the terminal mounting shell 1, with the two sets of fixing plates 2 arranged symmetrically. Each set of fixing plates 2 has two plates. A mounting hole is formed through the upper surface of each fixing plate 2, allowing the terminal mounting shell 1 to be securely installed on the equipment using bolts or other fasteners. A guide groove 11 is fixedly connected to the upper surface of the terminal mounting shell 1. A guide plate 8 is slidably connected to the inner wall of the guide groove 11, allowing the terminal block body 3 to be accurately installed into the terminal mounting shell 1. The side of the guide plate 8 away from the guide groove 11 is flush with the outer wall of the terminal block body 3. The terminal block body 3 is fixedly connected to a fixing component 7 at its bottom. A mounting groove 10 is provided at the bottom of the inner cavity of the terminal mounting shell 1, and a guide groove 12 is provided on the inner side wall of the mounting groove 10. A fixing groove 5 is provided through the outer surface of the terminal mounting shell 1, and the fixing groove 5 is connected to the guide groove 12. Three wiring grooves 6 are provided on the outer surface of the terminal block body 3, arranged in a linear array for connecting wires. Three threaded grooves 9 are provided through the upper surface of the terminal block body 3, arranged in a linear array, and connected to the wiring grooves 6. A fixing screw 4 is threadedly connected to the inner wall of the threaded groove 9, and the wire can be fixed in the wiring groove 6 by rotating the fixing screw 4.

[0018] In actual use, using bolts or other fasteners, the terminal mounting shell 1 is securely installed on the equipment using the mounting plate 2 through the mounting holes. The guide plate 8 on the terminal body 3 is moved into the terminal mounting shell 1 along the guide groove 11 to initially position the terminal body 3. The fixing rod 701 in the fixing assembly 7 is aligned with the mounting sleeve 702 in the mounting groove 10. The movable rod 703 is pressed to move into the mounting sleeve 702, which drives the movable block 705 to move into the mounting sleeve 702 and compresses the return spring 704. At this time, the movable rod 703 is aligned with the guide groove 12. Continue pressing the terminal body 3, and the fixing rod 701 in the fixing assembly 7 will be repositioned. The fixed rod 701 and the mounting sleeve 702 move downward along the mounting groove 10, and the movable rod 703 moves downward along the guide groove 12 until the terminal body 3 is completely inserted into the terminal mounting shell 1. At this time, the movable rod 703 moves to the fixed groove 5, the return spring 704 returns and pushes the movable block 705 and the movable rod 703 out of the mounting sleeve 702, and the movable rod 703 is inserted into the fixed groove 5, completing the connection between the terminal body 3 and the terminal mounting shell 1. The wire to be connected is inserted into the wiring groove 6 of the terminal body 3, and then the fixing screw 4 is rotated to move the fixing screw 4 downward, so that the wire is firmly fixed in the wiring groove 6.

[0019] Example 2: The fixing component 7 includes a fixing rod 701 fixedly connected to the bottom of the terminal block body 3. A mounting sleeve 702 is fixedly connected to the outer surface of the fixing rod 701. A movable block 705 is slidably connected to the end of the mounting sleeve 702 away from the fixing rod 701. A movable rod 703 is fixedly connected to the end of the movable block 705 away from the mounting sleeve 702. A limit block 706 is fixedly connected to the end of the mounting sleeve 702 away from the fixing rod 701 to prevent the movable block 705 from sliding out of the mounting sleeve 702. A return spring 704 is fixedly connected to the inner wall of the mounting sleeve 702. The end of the return spring 704 away from the inner wall of the mounting sleeve 702 abuts against the side of the movable block 705 away from the movable rod 703.

[0020] In actual use, when it is necessary to disassemble the terminal block body 3 and the terminal mounting shell 1, press the movable rod 703 to move it into the mounting sleeve 702 until it is disengaged from the fixing groove 5, and then pull the terminal block body 3 upward to complete the disassembly of the terminal block body 3 and the terminal mounting shell 1. The disassembled terminal block body 3 and the terminal mounting shell 1 are then recycled separately, realizing the separation of metal and plastic parts.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
