Description
Technical field
The present invention relates to a kind of wave detector, contact chip under especially a kind of wave detector.
Background technology
We know, seismic prospecting detector is sensor vibration signal being converted to electric signal.With reference to Fig. 1, wave detector inside is provided with magnet steel 11, magnet steel about 11 is respectively equipped with the yoke 12 of magnetic conduction, yoke 12 upper surface is provided with pilot hole, magnet steel 11 and upper lower yoke 12 form magnetic system, magnetic system is respectively equipped with upper cover 14 and lower cover 15 up and down, upper cover 14 and lower cover 15 are respectively equipped with positioning convex, positioning convex is positioned at the pilot hole of yoke upper surface, being arranged with outside magnetic system can the coil 13 of up-down vibration, shell 10 is arranged with outside coil 13, upper cover 14 and lower cover 15 are fixed by shell 10, upper cover 14 and lower cover about 15 clamp magnetic system simultaneously, coil about 13 is respectively equipped with the spring leaf up and down of support coils, upper cover 14 is provided with lead terminal, positioning convex 17 side of lower cover 15 is provided with locating slot, lower contact chip 16 is provided with in the positioning convex 17 of lower cover 15 and locating slot, lower contact chip 16 is made up of thin type sheet metal, lower contact chip 16 supports lower spring sheet 19, the circuit of coil is by the conducting of lower contact chip 16 simultaneously, electric signal is exported by the lead terminal on upper cover 14.
With reference to Fig. 2, existing lower contact chip is provided with external support ring 21 and inner conductive ring 22, the both sides external correspondence of external support ring 21 is provided with straight shape support edge 23, groove 26 is provided with in the middle of inner conductive ring 22, groove 26 direction is parallel with the straight shape support edge 23 of external support ring 21 both sides external, is provided with middle dowel 25 inside groove 26 with inside external support ring 21.
During use, with middle dowel 25 centerline direction for axis, lower contact chip external support ring 21 is converted into circular arc, simultaneously with middle dowel 25 with external support ring 21 tie point place for benchmark, by inner conductive ring 22 warpage certain altitude, and keep inner conductive ring 22 level.
With reference to Fig. 1, during installation, the inner conductive ring 22 of lower contact chip is placed positioning convex 17 upper end of lower cover, contact with the bottom surface of bottom yoke 12 internal holes, play the effect of connection signal simultaneously.The middle dowel 25 of lower contact chip is positioned at the locating slot of positioning convex 17 side of lower cover 15, the straight shape support edge 23 of external support ring 21 both sides external of lower contact chip is upturned, straight shape support edge 23 forms linear contact lay with lower spring sheet 19, the lower spring sheet 19 of support coils 13, also plays the effect of connection signal simultaneously.
Wave detector in use, be subject to side knock sometimes, coil can rotate by the axis direction of wave detector, to eliminate the destruction of this side knock to spring leaf brace rod, also magnetic system can be caused relatively to rotate relative to upper and lower covers simultaneously, this revolving force acts on the inner conductive ring of contact chip under wave detector, then the external support ring of lower contact chip is passed to by middle dowel, lower contact chip external support ring moment will easily produce distortion, this distortion power easily destroys the brace rod of spring leaf, the brace rod of spring leaf is caused to be out of shape, thus make the technical indicator of wave detector defective, and the serviceable life of wave detector is shortened, less reliable, finally cause using.
Summary of the invention
The present invention will solve the easy distortion of contact chip external support ring under existing wave detector exactly, thus cause that the technical indicator of wave detector is defective, shortening in serviceable life, less reliable, finally cause the technical matters that cannot use, provide a kind of the technical indicator of wave detector can be made to keep qualified, extend its serviceable life and contact chip under improving the wave detector of its reliability.
For this reason, the present invention is provided with external support ring and inner conductive ring, groove is provided with in the middle of inner conductive ring, middle dowel is provided with inside groove with inside external support ring, middle dowel is provided with torsion snubber assembly, and torsion snubber assembly is on middle dowel, be provided with two 180 ° parallel later bending Structure composing; Direction parallel with middle dowel outside external support ring is provided with arc convex.
The present invention due under wave detector in the middle of contact chip dowel be provided with torsion snubber assembly, when wave detector is subject to side knock, the revolving force of magnetic system passes to the external support ring of lower contact chip during by middle dowel, torsion snubber assembly can absorb this torsion, lower contact chip external support ring can not be passed to, lower contact chip external support ring can not be caused to produce distortion, thus the brace rod of protection spring leaf does not deform, ensure that the technical indicator of wave detector is qualified, the serviceable life of wave detector is extended, and reliability improves; Again due to direction parallel with middle dowel outside outside support ring being provided with arc convex; when wave detector is subject to side knock; when coil rotates with the axis direction of wave detector; the resistance of arc convex to spring leaf becomes the resistance of point cantact, instead of the linear contact lay resistance of straight shape support edge, so rotational resistance is very little; coil more easily rotates; the brace rod of further protection spring leaf does not deform, and ensures that the technical indicator of wave detector is qualified, improves reliability and serviceable life.
