Service Hotlinechurchill cityFasteners are a general term for a type of mechanical parts used to fasten two or more parts (or components) to form a whole. Among them, self-fastening fasteners are widely used in the connection of sheet metal parts due to their advantages of fast installation, high efficiency, reliability, convenient assembly, high push, pull and torsion performance, wide range of applicable materials and serialization of specifications. middle. Nuts are the most widely used type of fasteners. With the continuous change and development of the scope of use and the use environment, more demands are put forward for nuts. In particular, some occasions require the nut to have the function of waterproof sealing. The existing methods of nut sealing and waterproofing generally have the following types:
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 7 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
In real life, churchill citychurchill cityrivet nuts are used. With different specifications and different uses, many people are familiar with this tool but don't know how to use it properly.
