[0037] As mentioned in the background technology, the battery pack is an important component of new energy vehicles, which can be used as a power battery.

[0038] In the prior art, the rated working voltage of ordinary automotive-grade low-voltage plug-ins used in the heating and signal acquisition circuits of battery packs is below 60V, the PIN pin spacing is small and there is no isolation between the PIN pins, which cannot withstand high voltage testing and may cause high voltage ignition in harsh battery pack environments.

[0039] In view of this, please refer to Figure 1-Figure 7The electrical connector 1000, battery pack and vehicle provided in the embodiments of the present invention can solve this problem, which will be described in detail below.

[0040] A vehicle is provided in an embodiment of the utility model. The vehicle may be a new energy vehicle. The vehicle includes a battery pack. The battery pack may be used as a power battery of the vehicle. Specifically, the battery pack includes an electrical connector 1000. The electrical connector 1000 may be applied to a heating and signal acquisition circuit of the battery pack.

[0041] Specifically, please refer to Figure 1-Figure 5 The electrical connector 1000 includes a first connector 100 and a second connector 200. The first connector 100 includes a first connector body 110, an isolation plate 120, a first PIN needle (not shown) and a second PIN needle (not shown). The first PIN needle and the second PIN needle are arranged at intervals on the first connector body 110. The isolation plate 120 is arranged on the first connector body 110. The isolation plate 120 is located between the first PIN needle and the second PIN needle. The second connector 200 is detachably connected to the first connector 100, and the second connector 200 is connected to the first PIN needle and the second PIN needle at the same time.

[0042] Please note that, please refer to Figure 6 The first connector body 110 has a first PIN needle setting area 111 and a second PIN needle setting area 112 , the first PIN needle is set in the first PIN needle setting area 111 , and the second PIN needle is set in the second PIN needle setting area 112 .

[0043] Since an isolation plate 120 is provided between the first PIN pin and the second PIN pin, sparking between the first PIN pin and the second PIN pin can be avoided under high voltage conditions, and thus the electrical connector 1000 can withstand high voltage testing. Meanwhile, the electrical connector 1000 can be applied to a battery pack, avoiding high voltage sparking and circuit short circuit in the battery pack under harsh environments.

[0044] The second connector 200 being detachably connected to the first connector 100 can be understood as the first connector 100 and the second connector 200 being matched with each other, or the first connector 100 and the second connector 200 being detachable and separable.

[0045] Figure 1 It can be understood as a schematic diagram of the first connector 100 and the second connector 200 of the electrical connector 1000 being matched together. Figure 2-Figure 4 It can be understood as a schematic diagram of the first connector 100 and the second connector 200 of the electrical connector 1000 being disassembled and separated.

[0046] The isolation plate 120 and the first connector body 110 jointly define a first mating slot 101 and a second mating slot 102 that are separated. The first PIN needle is disposed in the first mating slot 101 , and the second PIN needle is disposed in the second mating slot 102 .

[0047] It is easy to understand that the first PIN needle setting area 111 may be located in the first matching groove 101 , and the second PIN needle setting area 112 may be located in the second matching groove 102 .

[0048] In this embodiment, the distance between the first PIN needle and the second PIN needle may be 6.8 mm.

[0049] Please refer to Figure 2 Combined with Figure 7 The second connector 200 includes a second connector body 210, a first mating portion 220 and a second mating portion 230. The first mating portion 220 and the second mating portion 230 are both connected to the second connector 200 plate body, and the first mating portion 220 and the second mating portion 230 are respectively mated with the first mating groove 101 and the second mating groove 102.

[0050] The first matching portion 220 and the second matching portion 230 are arranged at intervals, and the first matching portion 220 and the second matching portion 230 jointly define an escape space 201 , and at least a part of the structure of the isolation plate 120 is disposed in the escape space 201 .

[0051] It is easy to understand that in order to facilitate the first matching part 220 and the second matching part 230 to extend into the first matching groove 101 and the second matching groove 102 respectively, the isolation plate 120 can extend into the avoidance space 201. The entire isolation plate 120 can extend into the avoidance space 201, or a partial structure of the isolation plate 120 can extend into the avoidance space 201.

[0052] In addition, the first mating portion 220 and the second mating portion 230 are respectively provided with a first insertion hole 221 and a second insertion hole 231, and the first PIN needle and the second PIN needle are connected to respectively match the first insertion hole 221 and the second insertion hole 231, that is, the first PIN needle and the second PIN needle are connected to respectively insert into the first insertion hole 221 and the second insertion hole 231, so as to realize the normal matching of the two first connectors 100 and the second connector 200, so that the electrical connector 1000 can work normally.

[0053] Please refer again Figure 2-Figure 4The second connector 200 also includes a first sliding block 240, which is arranged on the first matching portion 220, and the first connector body 110 is provided with a first sliding groove 113, and the first sliding block 240 can be slidably matched with the first sliding groove 113. In addition, the second connector 200 also includes a second sliding block 250, which is arranged on the second matching portion 230, and the second connector body 210 is provided with a second sliding groove 114, and the second sliding block 250 can be slidably matched with the second sliding groove 114. The first sliding block 240 and the second sliding block 250 are both long strip structures.

[0054] During the cooperation between the second connector 200 and the first connector 100 , the first sliding block 240 can slide relative to the first sliding groove 113 , and the second sliding block 250 can slide relative to the second sliding groove 114 .

[0055] It should be noted that if Figure 1 as well as Figure 3-Figure 5 As shown, in this embodiment, the first sliding block 240 and the second sliding block 250 can be respectively adapted to the first sliding groove 113 and the second sliding groove 114 of the first connector 100 in this embodiment to achieve pairing of the first connector 100 and the second connector 200.

[0056] It is easy to understand that in other embodiments, the position of the first sliding groove 113 and the position of the second sliding groove 114 of another electrical connector 1000 may be different from the position of the first sliding groove 113 and the position of the second sliding groove 114 of the electrical connector 1000 in this embodiment.

[0057] This can avoid the situation where the first connector 100 and the second connector 200 of different electrical connectors 1000 are incorrectly paired.

[0058] In addition, please refer to Figure 6 , the first connector 100 is Figure 6 In this state, the height of the top side of the isolation plate 120 also needs to be greater than the height of the top of the first PIN pin, and the height of the bottom side of the isolation plate 120 is less than the height of the bottom of the first PIN pin. At the same time, the height of the top side of the isolation plate 120 needs to be greater than the height of the top of the second PIN pin, and the height of the bottom side of the isolation plate 120 is less than the height of the bottom of the second PIN pin, so as to avoid sparking between the first PIN pin and the second PIN pin under high pressure.

[0059] To summarize, the electrical connector 1000 includes a first connector 100 and a second connector 200. The first connector 100 includes a first connector body 110, an isolation plate 120, a first PIN needle and a second PIN needle. The first PIN needle and the second PIN needle are arranged at intervals on the first connector body. The isolation plate 120 is arranged on the first connector body 110.

The second connector 200 is detachably connected to the first connector 100, and the second connector 200 is connected to the first PIN needle and the second PIN needle at the same time.

[0060] Since an isolation plate 120 is provided between the first PIN pin and the second PIN pin, sparking between the first PIN pin and the second PIN pin can be avoided under high voltage conditions, and thus the electrical connector 1000 can withstand high voltage testing. Meanwhile, the electrical connector 1000 can be applied to a battery pack, and high voltage sparking and circuit short circuit can be avoided in a harsh environment, and the electrical connector 1000 of the battery pack can work safely.
