As shown in Figure 1, there is a 30 ° wedge-shaped inclined surface at the bottom of the female thread. When the bolt and nut are tightened to each other, the tip of the bolt is firmly pressed again

The threaded fasteners we currently use are either anti-loosening or self-locking. Some are originally lock nuts, but they are said to be self-locking nuts. So how to distinguish and distinguish? 1.

Generally, the nut will loosen due to some other reasons such as vibration during use. In order to prevent this phenomenon, a self-locking nut was invented. The function of self-locking nut is mainly

The self-tapping screws thread is relatively sharp. It can be rotated to eat into the smaller screw hole. The thread in the hole is developed by cutting and extrusion. The friction between the materi

1. The concept of distinguishing between connectors, terminals and connectors: 1. Connector, also called connector connector. It is a component often contacted by electronic engineering technicians.

Each device has a maximum power limit, whether it is an active device (such as an amplifier) or a passive device (such as a cable or filter). Understanding how power flows in these devices helps to h

The automobile production line is a production line for automobile operations. Its operation line procedures include welding, stamping, painting, powertrain and so on. To improve the automation level

The principle of self-locking lies in its unique structure. As shown in Fig. 1, there is a wedge-shaped slope of 30 ° on the bottom of the female thread. When the bolt and nut are tightened, the cus

Now China has a lot of parts processing factories, want to find the right processing companies are also a lot harder than before. In fact, we are not much difference in the technical above, the most

Connector knowledge The basic performance of connectors can be divided into three categories: mechanical, electrical, and environmental performance. Another important mechanical property is the mecha

he most fundamental resonant device is a dielectric resonator. To understand how a dielectric resonator works, first understand the metal waveguide and resonator. The designation of a quartz crystal
