Description

Floating plug protection device

Technical Field

The utility model relates to a floating plug protection device, and belongs to the technical field of automobile part testing systems.

Background

The detection of the automobile parts requires the energizing of the parts and the associated communication instructions. The automatic process generally uses an air cylinder and an electric cylinder to push a male plug connected with a related cable to form quick connection with a female plug on a workpiece through pressing. The connection between the interior of the male plug and the cable is typically a probe weld cable.

The probes of a male plug often need to be exposed slightly from the plug end face to ensure good contact. However, in some automobile parts production processes, there are often production process associated foreign matters falling, even there are process associated metal foreign matters falling to the end face of the plug to cause the short circuit of the probe head in the plug and to cause the short circuit of the plug, even the plug probe damages the probe and breaks down the insulation plug body between the probes because of overlarge short circuit current. Therefore, short-circuiting of plugs with more foreign matters in the production process is a common problem of downtime of production. Because the tolerance fit of the probe and probe-mounting body is very fine, many require fitting. The welding requirements of the probe and the cable are also high, so that the replacement of the short-circuit plug is time-consuming and labor-consuming.
