Technical Field
The utility model belongs to the technical field of spring touches and indicates test technique and specifically relates to spring touches digital special use detection frock that indicates.
Background
The spring contact fingers can transmit strong current in a small space. The use of the high-pressure-resistant rubber is not limited at all, and the high-pressure-resistant rubber is suitable for being used in various static or dynamic medium-high pressure environments. Each coil will independently compensate for contact and surface variations, which allows for wider tolerances between the fittings. The spring contact finger is a part for flexibly connecting two electric conductors and consists of an annular spring connected end to end; in the prior art, the spring contact finger is commonly used on a solid-sealed polar pole and an inflatable cabinet, the spring contact finger in the solid-sealed polar pole is used for connecting a conductive block and a wire outlet seat in a sliding connection mode, and the spring contact finger in the inflatable cabinet is used for a three-station connection effect. The spring contact finger insertion and extraction force and the loop resistance are important indexes for judging whether parts are qualified or not, too large spring contact finger insertion and extraction force can cause too large sliding block movement resistance, the sliding block movement is influenced, the closing speed of equipment is influenced, too small spring contact finger insertion and extraction force can cause poor contact of a sliding mechanism, the loop resistance is enlarged, and the temperature rise is caused.
Chinese patent No. CN201413211Y discloses an internal friction force detection tool for a spring finger. This detection tool includes: the detection seat and the detection hammer are characterized in that the center of the detection seat is a circular recess, an annular groove is formed in the peripheral wall of the recess and used for containing a spring contact finger, a positioning is arranged at the center of the circular recess of the detection seat and extends upwards to the outside of the detection seat, the positioning rod is connected with the detection seat into a whole, the detection hammer is composed of two cylinders with different diameters, the cylinder end with the smaller diameter is matched with the recess of the detection seat, a positioning hole is formed in the center of the detection hammer and used for positioning to penetrate through the detection hammer and match with the recess of the detection seat in a positioning mode.
The above prior art solutions have the following drawbacks: because the detection tool only uses two detection hammers to contact with the spring contact finger in the detection process, the spring contact finger insertion and extraction force and the loop resistance value cannot be accurately measured, and effective improved data cannot be provided for technicians.
