Helical coil spring is a spring round the Rao Rao line, wire coil is oval, tilt, when subjected to compression, each coil will produce separate deformation, no matter which part of the coil deformation, the spring will be the reaction, so as to realize the uniform load at each point of contact.
For connections, end of the spring will be welded together to form a complete ring, for each standard coil size specific insert or pull out the stress requirements in the design of the socket and plug, spring can be put into the groove. When the convex slot is inserted into the groove, helical coil spring spring deformation under the action of continuous spring, and will cause the resistance until the coil pair slot. At this time, the design of coil spring load and groove will produce a continuous spring stress, as a result, it needs a corresponding pullout strength to open the 2 parts, in the micro connector buckle, helical coil spring radial has 2 key functions, and can reduce the number of components in the system.
Helical coil spring with double function, can be used as a mechanical joint, can keep the circuit between the external thread joint and the inner screw thread joint, so that the RF interference is reduced to a minimum, for the more complex electronic interconnect design. Installation is simple and compact design for military, industrial, and provide a new test of interconnect design for commercial use. The circuit speed increases, and the size of electronic components to reduce. Therefore, connections require a higher processing speed more signals, in a smaller space or the number of contacts, in a more compact space more connections, the size is smaller, its unique - elastic deformation curve, adequate scope of work permit - spring compression up to 35%, the relative stability of the stretch reducing temperature difference, tolerance and other deviation caused by wear and tear, every spring coil can function alone
