Helical coil spring drawing oblique modeling _ coil spring coil spring is also called spring contacts that are round rao lines of spring, its spare wire coil is elliptical, tilted, when be compressed, each coil will produce deformation alone, no matter which part of winding deformation, the whole spring will be in reaction, so as to realize the load on each contact point.

For connectors, the end of the spring will be welded to form a complete loop, and the spring may be placed in a groove in socket and plug designs for specific insertion or withdrawal stress requirements at each standard coil size. When the convex groove is inserted into the groove, the inclined coil spring of the spring deforms under continuous spring stress and will cause resistance until the coil is paired with the groove. At this time, the inclined coil spring can also become a finger spring. The load of the spring coil and the design of the slot will create a constant spring stress, so that a corresponding pull force is required to disconnect the two components. The radial slant coil spring plays two key roles in the micro connector snap and reduces the number of components in the system.
