Background
In the prior art, the positions of the electric functions on the automobile are basically not separated from the connectors, and the more the electric functions are, the more the number of the connectors are used. In order to allow the connector to be installed in a compact space or to save space for other components, connectors in similar areas are often integrated. After the connectors are integrated, the number of terminals of each connector is increased due to the increase of the loops, and the insertion force of the connectors is also increased, and even the insertion force exceeds the operable range of hands, so that the assembly and the later maintenance of the product are affected.
For the problem of large insertion force of the multi-hole connector, a common solution is to add a lever power assisting mechanism to the connector sheath.
