Gu, realize to connect between contact arm and contact and do not incline, connect simple and convenient, accuracy, contact on the premise of beneficial to being oriented to
It is more reliable, effectively reduce contact resistance, it is to avoid the raising of temperature rise.
Preferably, described universal control device includes two universal joint cups, the bottom of universal joint cup is provided with
Half shape screw, half described shape screw coordinates with the internal thread hole on contact arm, and described universal joint cup is internally provided with universal
Section bulb.Structure mainly by upper and lower two universal joint cups, one bulb of matched moulds, in connection by half shape screw below,
It is fastened on contact arm, solves the problems, such as the shape position error that contact brings in contact arm installation process.
Preferably, described contact arm is provided with the cone space for containing universal joint cup.Ensure the contact of control device
Pressure and the firmness of connection.
Preferably, being provided with screwed hole on described universal joint bulb, set on described screwed hole alignment round panel
The hole put, the diameter of Kong Yukong is identical.Fastening effect between face and face ensure that contact is connected with contact arm and not incline.
Preferably, being provided with contraction spring on described contact, described contraction spring is circular constant force spring.It is circular
Constant force spring, is the distribution of screw type uniform force, and acts on radial direction.

Coordinate with static contact, on described round panel hole is provided with, what is coordinated with described contact 1 is universal control device, described
Universal control device be connected with contact arm 6 by half shape screw, be provided with Multifunction Sensor device 3, institute outside described contact 1
The universal control device stated includes two universal joint cups 5, and the bottom of universal joint cup 5 is provided with half shape screw, described half
Shape screw coordinates with the internal thread hole on contact arm 6, and described universal joint cup 5 is internally provided with universal joint bulb 4, and described touches
Arm 6 is provided with the cone space for containing universal joint cup 5, and screwed hole, described screw thread are provided with described universal joint bulb 4
The hole arranged on the alignment round panel of hole, the diameter of Kong Yukong is identical, and contraction spring 2 is provided with described contact 1, described
Contraction spring 2 is circular constant force spring, and described Multifunction Sensor device 3 includes built-in circumferentially punching Current Mutual Inductance line
Circle, built-in fluorescence temperature-measuring optical fiber temperature transducer, integrated control circuit plate.
When in use, the hole alignment universal joint bulb 4 on the round panel on contact 1, fastened with bolt, realize face with
The contact in face is fixed, and is coordinated with the internal thread hole on contact arm 6 using half shape screw between universal joint cup 5 and contact arm 6, whole dress
Putting connection status will not incline, it is ensured that realize omnidirectional's compensation on a large scale in the compensation of form and position tolerance, and described contact is corrugated,
The minimum place of ripple diameter has multiple contacts to coordinate with static contact, in the case where industrial manufacturing level permission of colding pressing is forged, touches
Contact on 1 is The more the better, and the wave on contact is The more the better, compared with conventional contact, with high contact intensity, can meet
