Abstract
Description
Technical Field
[0001] This utility model relates to the field of pin technology, and in particular to a pin with an anti-touch pin cap. Background Technology
[0002] The pins of electronic circuit connectors are used to transmit current and signals between wires and circuit boards. The model, size, and pin definitions must be confirmed to match the interface. During connection, if wiring is required, the insulation layer of the wires can be stripped, and the connectors can be fixed by crimping or soldering. Then, align the connector vertically with the socket hole and gently push it into place. Some connectors require a housing for secure connection. Power should be disconnected before operation. If a pin is bent, use tweezers to gently straighten it to avoid breakage or poor contact.
[0003] The pin caps on existing pins are mostly made of plastic or rubber, and their fixing method is only a simple elastic sleeve, that is, the slight friction between the inner wall of the pin cap and the outer wall of the pin tip is used to achieve the fit. This structure can barely maintain the fixation when stored at rest, but during transportation, the continuous shaking caused by vehicle bumps, stacking and squeezing can easily cancel out the friction between the pin cap and the pin tip by the vibration and impact force, and it is very easy to fall off. Once it falls off, the pin tip is directly exposed, which may not only cause deformation and wear of the pin tip due to collision, but also make it contaminated with dust, oil and other impurities, affecting the stability and conductivity of subsequent circuit connections, and even increasing the risk of operators being accidentally injured by the pin tip during use, highlighting the reliability defects of the traditional pin cap fixing structure in practical applications.
[0004] Therefore, it is necessary to invent a pin with a touch-proof cap to solve the above problems. Utility Model Content
