Now we can see its use everywhere, today we want to talk about the spring family, the existence of the more special, high-temperature resistant spring compression function. In fact, this refers to the tightening effect of the spring, in various occasions with its different characteristics.
For example: we all know that many household appliances will use high-temperature springs, especially in the electrical switches, the use is very common. And in the two contacts of the switch there will be a spring device, the main role is to ensure that the two ends of a tight touch, conductive outstanding. Of course, our high-temperature spring tight compression function is not good, then the switch contacts on the poor touch, the resistance will become large, the current through the period of heat generated, and in serious cases will be touching the metal melting.
What other aspects of the high-temperature resistant spring can be used in the tight pressure function?
1, in the use of electric lamps, a kind of bayonet head is also the use of high-temperature spring tight pressure role to adhere to the two metal column between the touch outstanding. As for the center metal piece of the screw-head lamp and all sockets are reeded metal piece, its function is to make the two sides tightly touch, in order to adhere to the same outstanding.
2, there is a long spring in the stapler its role on the one hand is the top tight staples, on the other hand, when the front of the nail is launched, you can send the nail to the front of the nail comfortable launch, so that it can take the initiative to push a nail to the front, until the nail all launched to stop.
3, in when the tape, there is a phosphor bronze reed, the use of its bending deformation occurs when the elasticity of the magnetic head and tape close touch.
4, the machine actively feed, like the clip on the clothes, ballpoint pens, pens on the set of the clip piece are using the spring of the tight pressure function of the clip on the clothes.
