Description

Technical Field

[0001] The utility model relates to the technical field of plug pins, and more specifically, to a plug pin structure. Background Art

[0002] In current electrical technology standards and product designs, the plug is the key interface for connecting electrical devices to power sockets. It usually consists of a plastic or metal shell and several metal pins, which are used to establish a stable electrical connection between the power socket and the electrical device. However, one design limitation of these plugs is that if the metal pins are damaged due to excessive use, mechanical damage, corrosion or any other form of wear and tear, it is often not possible to simply replace the damaged single pin. Instead, users usually need to replace the entire plug, which requires cutting the wires and installing a new plug, which may also involve stripping the wires and using special tools such as screwdrivers and wire cutters.

[0003] This not only increases maintenance costs for users, as they must purchase the entire plug instead of a single damaged part, but also increases the complexity of replacement, especially for ordinary consumers who are not familiar with electrician operations. This inconvenience may cause users to attempt replacements without the proper tools and knowledge, increasing electrical safety risks.

[0004] Furthermore, this design also has an adverse impact on the environment. Since the entire plug must be replaced, even if other parts are still intact, this leads to unnecessary waste and increases the generation of e-waste, which poses a challenge to achieving sustainable development goals.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a plug pin structure, which has the following beneficial effects:

[0018] 1. The disassembly mechanism realizes the rapid replacement of the plug pins, greatly improving the convenience of use and maintenance. The core lies in the mutual cooperation between the plug rod, insulating sleeve, threaded ring, threaded sleeve, clamping rod, baffle and insertion rod, so that the damaged plug rod can be easily removed and replaced with a new one, thereby reducing the replacement of the entire plug unit due to pin damage, reducing maintenance costs and improving resource utilization.

[0019] 2. The clamping mechanism provides a stable fixation for the pin through the combination of the ejector rod, annular groove, threaded sleeve and threaded ring. This mechanism ensures that during the replacement of the pin, the various components can fit closely together, and the pre-fixing effect is achieved through the thrust applied by the spring, and then the ejector rod is fixed by the threaded sleeve. This not only improves the safety of the pin, but also ensures the stability of the electrical connection, thereby avoiding safety hazards caused by unstable connection.

[0020] 3. The receiving mechanism realizes the stability and reliability of electrical connection through the coordinated work of the connecting rod, the positioning groove, the push spring and the clamping rod. When the plug rod is replaced, the positioning groove on the connecting rod cooperates with the inside of the insulating sleeve. This design not only ensures the stability of the electrical connection, but also improves the overall stability of the pin structure. BRIEF DESCRIPTION OF THE DRAWINGS
