Description

Technical Field

[0001] The utility model relates to the technical field of waterproof connector plugs, in particular to an industrial waterproof connector plug. Background Art

[0002] Industrial waterproof connector plug is an electrical connector designed specifically for industrial environments. It has excellent waterproof performance and can ensure stable and reliable electrical connections in humid, water-rich or harsh industrial environments. Its special sealing structure and design can prevent the intrusion of moisture and other liquids in industrial environments while providing stable electrical connections. Industrial waterproof connector plugs are widely used in various industrial fields that require waterproof connections, such as outdoor lighting equipment such as LED street lights and LED displays, which need to withstand the test of natural environments such as rain and fog; in marine environments, equipment is often corroded by seawater, salt and moisture. Industrial waterproof connector plugs can ensure the safety and reliability of electrical connections; communication base stations, network equipment, etc. installed outdoors or in humid environments require waterproof connectors to prevent equipment failures caused by moisture intrusion; the electrical connections of industrial automation production lines, robots and other equipment also need to use waterproof connector plugs to ensure stable operation of the equipment in humid environments.

[0003] Existing waterproof connector plugs have the following defects: First, the primary problem with current waterproof connector plugs is that their protective cover is not designed properly and cannot be easily fixed upright. This not only causes operational inconvenience during use, but also greatly increases the risk of accidental pinching of hands. In addition, the wiring part of the plug core is made of plastic. Although this design choice may have cost advantages in some aspects, it sacrifices stability and safety in high-temperature environments. Under high-temperature operating conditions, these plastic parts are very likely to melt or even cause fires, seriously threatening the safety of equipment and personnel. Second, the connection area between the female and male plugs adopts an integrated structure, which makes the wiring and installation process cumbersome and inconvenient. When users make line connections, they often face the challenges of limited space and complex operations, which affects work efficiency and user experience. The female plug cover and the male plug body are connected by a snap-on slot, which requires extremely high positioning accuracy during installation, which not only increases the difficulty of operation but also limits the flexibility of the connection. Since it cannot achieve a full 360° stable mounting, users may encounter problems such as loosening and falling off during use, which in turn affects the stability and reliability of the connector.
