Service HotlineMost of the capacitors on the market have two pins, which are the connection terminals of the positive and negative electrodes of the capacitor. At present, there is a big hidden danger in these capacitors, that is, the connection between the pins and the core inside the capacitor is basically a stick-on connection. When the capacitor is working, the internal temperature rises rapidly, and the stick-type connection is unstable after being heated, and it is easy to detach Or loose.
Therefore, how to provide a socket nut, a fastener and an installation method thereof that are more firmly connected and can be applied to thin-walled profiles is a technical problem to be solved by those skilled in the art.
At present, the main four kinds of anti-shedding nuts are still prone to falling off. Friction and anti-shedding are in the case of shock, vibration and variable load. At the beginning, the nut will decrease in preload due to relaxation. As the number of vibrations increases, the loss of preload will increase. The force increases slowly, eventually causing the nut to loosen and the threaded connection to fail. The mechanical nut is prevented from falling off by adding a stopper, which makes it inconvenient to disassemble. The riveting and punching prevention is to prevent the separation by welding, bonding, etc. This method can only be disassembled by destroying the bolt pair.
Standardized mechanical parts for fastening connections. Standard fasteners mainly include bolts, studs, screws, set screws, nuts, washers and rivets. There are many structural types of bolts, and most of the heads are hexagonal. For bolts subjected to shock, vibration or variable load, in order to increase flexibility, the polished rod part is made into thin sections or hollows. The seat end of the stud is screwed into the threaded hole of the connected piece, and the nut used at the nut end is similar to the bolt nut. The structure of the screw is basically the same as that of the bolt, but the shape of the head is various to adapt to different assembly spaces, tightening degrees and connection appearances. Set screws have different head and tip shapes to accommodate different levels of tightening. Nuts are also available in a variety of styles, with hexagons being the most widely used.
There is a standard for the outer hexagon bolt standard, which is a grade standard, which is divided into grade 4.8 and grade 8.8. These two levels are used a lot in the market. Especially grade 4.8 hex head bolts. Because it is much cheaper than 8.8 hex bolts. Of course it is more widely used. But for demanding products. Because of its high requirements in various aspects such as hardness. This requires the use of 8.8 hex bolts. Grade 8.8 hex bolts are harder in terms of hardness and screw torque. It is safer to use the product. Tighter and more stable.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: ring hanging bolts, 8.8 grade GB6173 fine thread thin nuts, 3456 countersunk head bolts, square head cylindrical screws and other products, we can provide you with suitable products Your fastener solution.
