Description

Technical Field

[0001] The utility model relates to the technical field of pin terminals, in particular to an oxidation-resistant bolt-type pin terminal. Background Art

[0002] The pin terminal is an important connector for connecting wires and cables to electrical equipment. In actual use, corresponding matching pins and terminals are required to fix the terminals to electrical equipment to fix the wires and cables. Since the terminals in the prior art are generally copper tube structures, if they are not properly stored after leaving the factory, such as being directly stacked and exposed to the air after the packaging bag is opened, an oxide film or other dust and other pollutants may easily form on the contact surface of the inner wall of the terminal, which may easily cause poor contact during use, affecting work efficiency, and also reducing the service life of the terminal, resulting in a waste of resources.

[0011] Preferably, there are two groups of limit blocks, which are centrally symmetrically arranged, and the two groups of limit blocks can enter and be stuck in the inside of the limit groove.

[0012] Preferably, a movable plate is provided on the surface of the sealing plate, the movable plate is rotatably connected to the sealing plate, a spring is connected to the surface of the movable plate, and the other end of the spring is connected to the surface of the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] During normal use of the utility model, the pin is inserted into the terminal, the pin is rotated to align the positioning block with the positioning groove, and the pin is continued to be moved downward until the spring is fully compressed. At this time, the limit block enters the limit groove, and the pin is continued to be rotated to rotate the sealing plate, and then the limit block is rotated by a certain angle and stuck in the limit groove. During the movement of the sealing plate, the abrasive particles are driven to fully scrape the inner wall of the terminal. The abrasive particles can effectively remove possible oxides, and the scraped oxide impurities are collected in the dust collecting tank to keep the contact surface clean. At the end of use, the pin is rotated in the opposite direction at a certain angle to make the limit block leave the limit groove, and then the pin is pulled out. The elastic force of the spring lifts the sealing plate upward. At this time, the sealing strip completely seals the opening to block dust and moisture in the air from entering and prevent the inner wall of the terminal from oxidizing.
