Description

Technical Field

[0001] The utility model relates to a magnetic ring plastic shell forming die for an automobile battery pack sensor. Background Art

[0002] The automotive battery pack includes battery cells, a box for placing the battery cells, high-voltage wiring harnesses, low-voltage wiring harnesses, high-voltage power-off systems, battery cell management systems, thermal management systems, etc. In order to monitor the current, voltage and temperature of the battery pack during charging and use, sensors are generally installed at the ports of the high-voltage wiring harness. In order to fix and protect the magnetic ring in the sensor, the magnetic ring is usually installed in a matching plastic shell.

[0003] In order to increase the rigidity of the plastic shell, the conventional practice is to first produce the plastic shell with the help of a molding mold and set an open surface on one side thereof, and then embed the metal bar into the interior of the plastic shell after it is formed. However, since the open surface is set on one side of the plastic shell, although the metal bar can be fixed with the help of a clip set inside the plastic shell after embedding, the metal bar can easily fall off due to frequent vibrations, so the reliability of use is not high; in addition, the bracket used to connect other components and the threaded holes in the bracket also need to be installed separately after the plastic shell is formed, so the processing steps are relatively cumbersome, time-consuming and labor-intensive, and need to be further improved.
