Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1:

a fixing device for an electrical test conductive head comprises a groove plate 7, a ball sleeve 3 and a ball body 10, wherein fixing shafts 4 are respectively fixed on two sides of the ball sleeve and are fixedly bonded, the ball sleeve is a plastic ball sleeve, the fixing shafts are made of plastic materials, the fixing shafts are fixedly connected with the groove plate, the ball body is located in the ball sleeve, an outer sleeve 6 is fixed at the bottom of the ball sleeve, an inserting rod 8 is inserted in the outer sleeve, the inserting rod is fixed with a magnet 11 after being sleeved with a spring 12, the fixing is fixedly bonded, and the magnet and the ball body are attracted;

the ball body is characterized in that a round hole 2 is formed in the center of the ball body, a threaded through hole 9 is formed in the top of the ball body, and a fastening bolt 1 is connected to the threaded through hole in a threaded mode.

Example 2:

according to the fixing device for the electrical test conductive head in the embodiment 1, the magnet is a spherical magnet matched with the spherical surface of the sphere.

Example 3:

according to the fixing device for the electrical test conductive head in the embodiment 1 or 2, the ball sleeve is provided with the notch 5.

Example 4:

an electrical testing contact head fixture as in

embodiment

1 or 2 or 3 wherein said ball is an iron ball.

The working principle is as follows: when in use, two devices are selected to respectively fix the two conductive heads 13 of the testing device, the conductive heads penetrate through the circular holes of the devices, then the inserted bar is pulled according to the position of the original piece to be tested, so that the magnet is separated from the ball body, the fastening bolt is screwed, so that the fastening bolt is fixed on the conductive head to fix the conductive head, the device is moved to the position of the testing original piece, the conductive head is held by hand to rotate the ball body, the conductive head faces the position of the testing original piece, the inserted rod is loosened after the angle of the conductive head is adjusted, the inserted rod moves upwards under the action of the spring, the magnet is attracted with the sphere again, the position of the sphere can be fixed, then the mobile device makes the tip contact test original paper of conductive head realize electric test, and this fixing device can guarantee simultaneously that the position of conductive head is motionless, does not need operating personnel to hold the conductive head with the hand and tests.
