Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-3, a stable type electrical connector includes a socket 1, a plug 2 mating with the socket 1, wherein the socket 1 is a battery pack end power changer part, the plug 2 is a vehicle end power changer part, four groups of positioning structures are arranged between the plug 2 and the socket 1, and four groups of positioning structures are uniformly distributed around the socket 1, each positioning structure comprises a positioning bulge arranged on the plug 2 and a positioning hole 3 arranged on the socket 1 and matched with the positioning bulge, four limiting holes 4 are arranged in the socket 1, an adjusting sleeve 5 is arranged in each limiting hole 4, the cross section size of the limiting hole 4 is larger than that of the adjusting sleeve 5, the adjusting sleeve 5 is provided with a limiting structure for preventing the adjusting sleeve from separating from the limiting hole 4, and each positioning hole 3 is formed in the corresponding adjusting sleeve 5.

Therefore, when the plug 2 is matched with the socket 1, namely, when the battery is replaced, the battery pack connector can be easily led into the vehicle-end connector only by slightly exerting force at the offset of + -1.5mm, the success rate of replacing the battery is improved, the instability of the original XY-direction connector offset correction in the battery replacement is reduced, and the situation that a contact pin is not easy to deform is ensured.

In this embodiment, preferably, the limiting hole 4 is a circular hole, and the adjusting sleeve 5 is cylindrical, so that only the diameter of the adjusting sleeve 5 needs to be set smaller than the diameter of the limiting hole 4, and the automatic deviation rectification stability in the XY direction is good, although the shapes of the limiting hole 4 and the adjusting sleeve 5 are not limited to the above shapes, and other shapes can also be adjusted.

In order to prevent the adjusting sleeve 5 from being separated from the limiting hole 4, the limiting structure comprises limiting parts 6 arranged at two ends of the adjusting sleeve 5, and the cross section size of each limiting part 6 is larger than that of the positioning hole 3.

In this embodiment, preferably, a ground protection circuit, a high voltage high current circuit, a high voltage auxiliary circuit and a low voltage signal module circuit are disposed between the socket 1 and the plug 2, the high voltage high current circuit has at least three groups, the low voltage signal module circuit has at least two groups, the high voltage auxiliary circuit includes a BMS auxiliary working power circuit and a high voltage signal auxiliary power circuit, two groups of high voltage high current circuits and a group of low voltage signal module circuits are added, in addition, an independent BMS auxiliary working power terminal and a high voltage signal auxiliary power supply are added for heating, and more signals can be collected to a vehicle end or a BMS end by increasing the number of pins of the auxiliary high voltage and low voltage signal terminals.
