Example 1

Referring to fig. 1 to 3, the connector for a laminated battery box of the present embodiment includes three parts, a connector receptacle 100, a connector plug 200, and a conductive copper bar 300.

The four corners of the connector socket 100 are respectively provided with a fixing hole 110, and the connector socket 100 is fixed on the side wall of the battery box through the 4 fixing holes 110.

The connector socket 100 is provided with a plurality of protruding rotary buckle assemblies 120 at intervals, the rotary buckle assemblies 120 are in a shape of a Chinese character 'shan', and protruding parts are pointed ends of the Chinese character 'shan'. A plurality of protruding second rotating fastening components 220 are disposed on the connector plug 200 at intervals, and the second rotating fastening components 220 are mutually engaged with the first rotating fastening components 120. When the connector plug 200 is fully mated with the connector receptacle 100, the connector plug 200 is adjusted such that the second rotary latch assembly 220 snaps into the neutral position of the first rotary latch assembly 120. Because the first rotary latch assembly 120 is in a zig-zag shape, the top is pointed, and when the second rotary latch assembly 220 is engaged into the neutral position of the two adjacent first rotary latch assemblies 120, the connector plug 200 can be prevented from rotating excessively or in a wrong direction, so as to avoid damage.

The connector socket 100 is provided with a first high-voltage connection terminal 130 at a central position, and a second high-voltage connection terminal 230 is provided in the connector plug 200. When the connector plug 200 is completely docked with the connector receptacle 100, the second high-voltage connection terminal 230 is docked with the first high-voltage connection terminal 130, and the current is conducted.

The connector socket 100 is provided with a high voltage interlock 140, and when the connector plug 200 is docked with the connector socket 100, current is conducted, a high voltage connection state can be determined by the high voltage interlock 140, and an abnormal alarm is given.

The connector socket 100 is provided with an annular stop assembly 150, and the connector plug 200 is provided with a button buckle 210. After the connector plug 200 is mated with the connector receptacle 100, the button catch 210 is depressed and the stop assembly 150 blocks the button catch 210 so that the connector plug 200 cannot be removed from the connector receptacle 100.

The copper bar connecting terminal 310 is arranged at the tail end of the conductive copper bar 300, and the shape of the conductive copper bar 300 can be freely adjusted according to the shape of the battery box, so that the space of the whole machine is saved. The copper bar connection terminal 310 and the second high voltage connection terminal 230 are tightly connected in the connector sheath.

The conductive copper bar 300 is externally provided with a shielding wire and an insulating rubber sheet, so as to ensure the waterproofness and electromagnetic radiation performance of the whole laminated battery box.

The conductive copper bar 300 is made of copper, and is circular in shape, and the diameter of the conductive copper bar 300 is determined according to the passing current-carrying capacity. When the conductive copper bars 300 are used for connecting battery packs with different spans, copper with different hardness is adopted, when the spans of the two battery packs are far, the conductive soft copper bars 320 are used, and when the spans of the two battery packs are near, the conductive hard copper bars 330 are used, and the principle is an integrated optimal scheme, and can be designed without influencing the normal operation of a battery system according to the principle.

With reference to fig. 4, a plurality of battery packs 500 are assembled in a battery holder 400 to form a stacked battery case. In the cushion layer battery box, the first battery main cathode 510 at the uppermost layer is connected to the second battery main cathode 520 at the lowermost layer through the conductive soft copper bar 320, and the first battery main cathode 530 at the upper layer is connected with the second battery main cathode 540 at the next layer through the conductive hard copper bar 330. The conductive copper bars 300 all follow the principle of using a conductive hard copper bar 330 for short span copper bars and a conductive soft copper bar 320 for long span copper bars. Besides the two-branch connection scheme of the battery pack in the illustrated laminated battery box, the volume density requirement can be changed into a scheme of 3 branches and the like according to the actual cruising requirement of the vehicle.

As can be seen in fig. 5, the conductive copper bars 300 are integrally protruded and shortened by at least 150mm compared to the conventional cable 600. In addition, the conductive copper bars 300 are connected in a high hardness manner, so that the problem of large vibration of the conventional cable 600 is avoided.

The above examples illustrate only certain embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model, it being understood that variations and modifications can be made by those skilled in the art without departing from the spirit of the utility model, which is within the scope of the utility model, and the appended claims shall therefore be construed as defining the scope of the utility model.
