Some electronic products need to install some plastic parts or protective sleeves for components on the PCB, which need to be fixed by screws. The function of the fixture is to locate the PCB and the required installation parts, and increase the work efficiency. The existing screw fixture is inconvenient According to the needs of the site, the positioning station of the screw can be changed, the accurate positioning of the screw is difficult and the clamping effect of the workpiece is poor. A screw jig is proposed.

The materials of rubber gaskets are usually NBR (nitrile butadiene rubber), SBR (styrene butadiene rubber), HNBR (hydrogenated nitrile butadiene rubber), EPDM (EPDM rubber), SILICONE (silica gel), VITON (fluorine rubber), CR ( Neoprene), FFKM (perfluoroelastomer), etc.

Many customers ask what is the difference between a rivet nut and a rivet nut, and how to use it? Let's take a look at the difference between a rivet nut and a rivet nut with Yueluo. First of all, in terms of appearance, you can look at the differences in appearance. In terms of appearance, the difference between the rivet nut and the pressure rivet nut is still very big, but their main functions are almost the same. They all provide threads for thin plates, but the way of installation is different. The method of installation greatly determines the purpose and use of a nut. First of all, the installation method of the riveting nut is to use the riveting equipment to carry out the riveting, so it is suitable for use in the place where the riveting is not easy for the square tube and the round tube. The rivet nut also makes up for some of the shortcomings of electric welding, such as aesthetics, and places that are not easy to weld, such as thin plates.

The key connection is a typical mechanical connection, which is usually used to connect the parts on the shaft and to fix them circumferentially and realize torque transmission. Key connection can be divided into flat key connection, semicircular key connection, wedge key connection and tangential key connection, among which flat key connection is widely used in practical engineering because of its simple structure, good alignment and convenient manufacturing. During operation, torque is transmitted through the contact between the sides of the key and the sides of the shaft and hub grooves. In order to ensure the transmission accuracy, the flat key structure generally adopts the transition fit. Due to its structural characteristics and working conditions, it is difficult to use ordinary mechanical tools to lift and pull out during the maintenance process. If forcibly removed, the key and the mating shaft will be destroyed.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: combination complete, A450 toothed nuts, hexagon socket expansion bolts, link buckle carabiner and other products, we can provide you with suitable fasteners for you solution.
