With the development of new energy vehicles, the new energy vehicles and the like and vehicles gradually move to thousands of households, and energy supply components of the new energy vehicles are used for supplying electric energy to motors of the vehicles through high-voltage plug-in units in connectors. Usually, the socket housing of the connector is fixedly connected to the panel, and after the socket housing is fixedly mounted on the panel, the high-voltage plug-in is mounted in the socket housing, and the panel equipped with the connector is fixed outside the battery pack to realize power supply transmission. The panel and the socket housing are usually fixedly connected through other components, and in the process of assembling the high-voltage plug-in unit to the socket housing, the high-voltage plug-in unit and the socket housing are easily inserted incorrectly, which results in a complicated and time-consuming process of assembling the connector to the panel.

In the integrated panel 100 of the present application, the panel plate body 10 and the socket housing 30 are integrated into an integral structure, and the socket housing 30 does not need to be assembled on the panel plate body 10, so that the assembly process of the integrated panel 100 is simplified, and the assembly time is saved; the third bosses 37 with different lengths are arranged outside the socket shell 30, and when the high-voltage plug-in 20 is assembled to the socket shell 30, the third bosses 37 in the accommodating cavity 31 can be used for positioning, so that the problem that the high-voltage plug-in 20 in the assembled connector is wrongly inserted or reversely assembled is avoided, and the installation time is further saved.

Referring to fig. 9, the high-voltage package 20 includes a conductive core 21, the conductive core 21 is located in the socket housing 30 (i.e. in the receiving cavity 31), and the conductive core 21 is connected to the high-voltage package 20 through the socket housing 30 and received in the receiving cavity 31.

The integrated socket housing 30 of the integrated panel 100 is formed on the panel body 10 by integrally molding the panel body 10 and the socket housing 30 through a die-casting process, so that the socket housing 30 is not limited in the positioning hole by the positioning hole formed on the panel body 10, and the integrated integration level is high.

The integrated panel 100 is assembled with the high voltage connector 20 fitted to the socket housing 30 after the socket housing 30 is integrated on the panel board 10.

In the integrated panel 100, the first bosses 33 and the second bosses 35 with different lengths on the socket shell 30 are designed to meet the fool-proof requirement of the conductive core 21, and meanwhile, the third bosses 37 with different lengths on the socket shell 30 are designed to ensure the accuracy of assembling the high-voltage plug-in unit 20. Among them, the length mentioned in the present application may be a distance extending in the X direction shown in fig. 3.
