The bevel coil spring is a circular wire spring, the wire coil is elliptical, inclined, when tightened, each coil will deform independently, no matter which part of the coil is deformed, the entire spring will react, so as to achieve consistent load at each contact point.
In the case of connectors, the ends of the springs are welded together to form a complete ring, and for the detailed stress requirements on each standard coil scale, the springs can be placed in recesses in the receptacle and plug planning. When the convex groove is pierced into the groove, the coil spring of the spring deforms under the continuous spring stress effect and will form resistance until the coil is paired with the groove.
At this point, the load of the spring coil and the planning of the groove will produce a continuous spring stress, so that a corresponding pull-out force is required to disconnect these two components, and the radial bevel spring has two key effects on the snap of the miniature connection and can reduce the number of components in the system.
The beveled coil spring provides a two-layer function that can be used as a mechanical joint or to maintain the circuit between the male and female fittings, so that RF disturbance is reduced to a small Z and the interconnection planning for electronics is more messy.
As a result, connectors need to process more signals in less space at higher speeds, or, in a more compact space, the larger the number of contacts, the smaller the scale of the connectors, its unique elastic force – deformation curve, wide operating range – springs that promise tightening by up to 35%, relatively stable spring force to reduce wear caused by temperature differences, tolerances and other deviations, each coil can work on its own.
Due to the particularity of the spring contact structure, the general spring stiffness check is transformed into a check of the plugging force (or stress strain) of the spring touch, and the test of this index is carried out in the imitation operation state: first apply a force to the spring finger, and then investigate its deformation to check the "soft" and "hard" degree of the spring, which is directly related to whether the high-voltage switch is smooth in the process of opening and closing.
