Service HotlineElectrical contact element is a kind of low-voltage electrical products and household electrical products widely used in switches, relays, thermostats, circuit breakers, contactors, controllers, timers, etc. There are mainly three types of electrical contact elements. 1. Riveting parts , riveting the rivet on the copper piece; 2. Welding piece, welding the sheet contact on the copper piece; 3. Stamping piece, punching the composite tape into components. Existing rivet contacts on the market at present are usually all made of precious metals, such as a simple metal matrix such as gold or silver. Its electrical contact performance is limited by a single metal material, and its electrical contact performance is poor; and due to certain requirements for metal purity in production, production efficiency is low, and production costs are high, resulting in the production of products that cannot be sold on a large scale in the market. and application.
When using ordinary hexagon head bolts or ordinary T-bolts with the oval groove structure, the bolts need to be inserted from the back of the groove. When the bolts cannot be inserted from the back of the groove due to the structural limitations of the steel base or the platform itself, it is often necessary to open the installation surface. Large diameter hand holes allow for easy mounting of bolts, which weakens the inherent strength and rigidity of a steel base or platform.
double-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
Swimming self-locking nut GJB 125.1～125.6-86 The double-ear sealing swimming self-locking nut is composed of four parts: sealing cover, self-locking nut, pressure ring and sealing ring. It has compact structure and reliable sealing, and is suitable for products whose working pressure is not more than 2atm, working medium is gasoline, kerosene, water or air, and the operating temperature is -50～100℃. However, it has certain difficulties in the manufacturing process and air tightness test.
The main function of the spring washer is to prevent the nut from loosening. It is also known that: the existing spring washer is a ring made of spring steel, and then a gap is cut in the diameter direction on the ring, and the heads on both sides of the gap are cut. The material of the part is turned to two different sides of the ring to form a pawl, and the purpose of preventing loosening is achieved by the fit between the pawl and the nut on the surface and the workpiece. Obviously, only one pawl is used to achieve the purpose of preventing loosening. Since the braking force generated by one pawl is limited, there are defects of poor braking effect and poor anti-loosening effect.
