Problems solved by technology

[0002] When the applicant conducts connection testing, sometimes it is necessary to connect the pins of the original components before testing, but often encounters the situation that the pins of the original components are difficult to eat tin, resulting in excessive contact resistance between the components, which greatly affects To ensure the accuracy of the detection, simply binding two pins that do not eat tin still cannot reduce the contact resistance between the two originals. The existing electric welding, argon arc welding, etc., are extremely difficult to weld. If you are not careful, you will damage the pins

Embodiment 1

[0018] The present invention adds a magnetic pulse auxiliary welding device on the basis of the workbench. The magnetic pulse auxiliary welding device utilizes the characteristic that the supercapacitor 1 can generate a large current discharge. pins, so that a large current flows through the contact area of ​​the two pins, and the contact area of ​​the two pins is heated by high temperature. In most cases, after the welding is completed, the two pins will be disconnected with a slight external force, and the contact resistance will still not decrease. Through further research, we found that after applying a pulsed magnetic field to the first conductive fixed rod 3 and the second conductive fixed rod 4, the success rate of welding the two pins can be greatly improved, and the contact resistance of the two pins can be greatly reduced. The specific method Yes: the first conductive fixed rod 3 is covered with a first ferrite tube 8, the outer side of the first ferrite tube 8 is ...

Abstract

Provided is an electrical engineer electrical appliance connection detection workbench comprising a platform plate, a first pulse generator and a second pulse generator. A magnetic pulse auxiliary welding device is mounted at the upper part of the platform plate; the magnetic pulse auxiliary welding device comprises a fixing support. According to the invention, the magnetic pulse auxiliary weldingdevice is additionally arranged on the basis of a workbench; according to the magnetic pulse auxiliary welding device, the characteristic that a super capacitor can generate large-current discharge is utilized; a first clamping plate and a second clamping plate are matched to clamp two pins to be welded; therefore, the large current flows through the two pin contact areas, the two pin contact areas are heated by high temperature, but although the two pin contact areas are singly heated to realize direct welding of individual pins, the two pins are disconnected by slight external force after fusion welding is completed in most cases, and the contact resistance is still not reduced.

Description

technical field [0001] The invention relates to a workbench, more precisely, an electric engineer's electric appliance connection detection workbench. Background technique [0002] When the applicant conducts connection testing, sometimes it is necessary to connect the pins of the original components before testing, but often encounters the situation that the pins of the original components are difficult to eat tin, resulting in excessive contact resistance between the components, which greatly affects To ensure the accuracy of the detection, simply binding two pins that do not eat tin still cannot reduce the contact resistance between the two originals. The existing electric welding, argon arc welding, etc., are extremely difficult to weld. If you are not careful, the pins will be damaged. Contents of the invention [0003] The purpose of the present invention is to provide a workbench for electrical connection detection of electrical engineers, on the basis of the workb...
