Description

Technical Field

[0001] The utility model belongs to the technical field of wiring terminals, in particular to a protection mechanism for wiring terminals. Background Art

[0002] Terminal blocks are a type of accessory used to achieve electrical connections, and are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks is gradually increasing.

[0003] Among them, after searching, it was found that there is an application number CN202223218950.0, which discloses a multi-terminal wiring protection structure, including a mounting body, a mounting hole is opened on the mounting body, and a wiring terminal protection is screwed in the mounting body. It has a setting through a mounting hole, a connecting groove, a protective plate, a baffle, a socket, a plug rod, an adjustment groove, a toggle plate and a first spring. When the protective plate is pushed to be placed in the connecting groove, when the plug rod corresponds to the socket, the elastic force of the first spring pushes the plug rod to be inserted into the socket to limit the protective plate, thereby exposing the wiring terminals in the mounting body to the outside, so that the protective mechanism of the wiring terminals is more convenient to disassemble and assemble, and the equipment will not be damaged due to disassembly and assembly. Through the setting of the second spring, when the protective plate blocks the mounting hole, the elastic force of the second spring can limit the protective plate in the mounting hole, thereby improving the stability of the protective plate in the mounting hole.

[0004] However, after research, it was found that the protective structure does not have a moisture-proof structure for the wiring terminals. The wiring terminals will be corroded by moisture and the protective effect is not good enough. The protective structure cannot specifically prevent dust from being used on individual unused wiring ports and is not flexible enough to use. Therefore, a new device is provided to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a protection mechanism for a wiring terminal in order to solve the above-mentioned problems of insufficient protection effect and insufficient flexibility in use.

[0006] The technical solution adopted by the utility model is as follows: a protection mechanism for a wiring terminal, comprising a protection shell, the protection shell is arranged in a U shape, a protection plate is arranged above the protection shell, and a through opening is arranged at a position corresponding to the interface of the wiring terminal on the surface of the protection plate;

[0007] A protective mechanism that can assist in moisture-proofing is arranged inside the protective shell.

[0008] Among them, the protective mechanism includes a cavity, a sealing plate, a magnetic strip A and a magnetic strip B. The protective shell is embedded with a cavity, and the inner wall of the protective shell is provided with a plurality of punching holes communicating with the cavity, and the bottom of the protective shell is provided with an opening communicating with the cavity. The opening of the protective shell is slidably connected with a sealing plate through a slide rail, and a magnetic strip A is embedded and installed on one side of the sealing plate, and a magnetic strip B is embedded and installed on the edge of one side of the opening of the protective shell corresponding to the magnetic strip A.

[0009] Among them, connecting rods are symmetrically fixedly installed on both sides above the protective shell, a groove is embedded on one side of the upper end of the connecting rod, a sliding rod is fixedly installed inside the groove, and a spring ring is nested in the sliding rod, and a spring block is nested and slidably connected outside the sliding rod, and the spring block is set in a triangular shape, and through holes that fit the connecting rods are set on both sides of the protective plate, a dustproof plate is slidably connected to the inside of the through-hole of the protective plate through a sliding rail, and the dustproof plate and the protective plate are elastically connected by a spring, and mounting screws are symmetrically embedded with threads on both sides of the protective plate, and a pressure plate is fixedly installed at the end of the mounting screw.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the utility model, the silica gel desiccant absorbs the moisture inside the protective shell through the protective mechanism, providing a dry environment for the wiring terminals, avoiding the wiring terminals from being damaged by moisture, and achieving a better protective effect.

[0012] 2. In the utility model, the sealing plate is easy to disassemble, and the silica gel desiccant inside the cavity is easy to replace. The protective plate and the protective shell can be fixed by passing the connecting rod through the through hole on the surface of the protective plate. The mounting screw is turned to press the pressure plate on the wiring terminal, so that the wiring terminal can be fixed in the protective shell, which is more convenient to use.

[0013] 3. In the utility model, when it is necessary to connect an external wire to the terminal interface, slide the dustproof plate at the corresponding interface to expose the opening, and connect the wire to the terminal interface. When the interface is not connected to the external wire, the dustproof plate blocks the opening of the corresponding interface under the action of the spring force, and blocks and seals the opening, so that each interface of the terminal is independent. The dustproof plate can block the idle interface from dust, which is more flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Align the through hole of the protective plate 102 with the connecting rod 1022, and clamp the protective plate 102 on the protective shell 1. After the connecting rod 1022 passes through the through hole, the spring block 1031 pops out from the groove 1032 under the action of the elastic force of the spring coil and is clamped above the protective plate 102, fixing the protective plate 102 and the protective shell 1 together.
