Labeled as:

1. the plug-in components are connected in a total positive mode, 2, MSD, 3, the temperature acquisition plug-in components, 4, the low-voltage signal plug-in components, 5, the total negative plug-in components, 6, the sealing strips, 7, the locking screws, 8, the copper bar, 9 and the panel.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation. It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

As shown in fig. 1, an integrated connector structure includes a panel 9, a total positive connector 1, a total negative connector 5 and an MSD (manual maintenance switch) 2, which are disposed on one side of the panel 9, wherein the total positive connector 1 and the total negative connector 5 are respectively disposed on two sides of the MSD. The structure arrangement can realize the quick installation and connection of the electric connection parts of the total positive and total negative and manual maintenance switches in the battery pack.

Still be equipped with temperature acquisition connector 3 on the panel 9, temperature acquisition connector 3 locates always and just connects the downside of plug-in components 1, and the purpose makes the integrated temperature acquisition function on the panel. Furthermore, a low-voltage signal connector 4 is arranged on the panel 9, and the low-voltage signal connector 4 is arranged on the lower side of the general negative connector.
