Description

High-voltage distribution box, battery pack and vehicle Technical Field The present disclosure relates to the technical field of vehicle accessories, and in particular, to a high-voltage distribution box, a battery pack, and a vehicle. Background In the related art, the electrical connection of the high voltage distribution box generally adopts an assembly structure of a connector, that is, a male end of the connector is inserted into a female end at an outer side of the high voltage distribution box, so as to realize the electrical connection of the wire harness and the high voltage distribution box. The male end and the female end are easy to shake due to external influence, so that the connection is invalid and even the terminal falls off. Disclosure of utility model An object of the present disclosure is to provide a high-voltage distribution box, a battery pack, and a vehicle, which can improve the reliability of wire harness connection. In order to achieve the above object, the present disclosure provides a high-voltage distribution box including a housing, a connector, and a wire harness fixed to the housing through the connector, the wire harness extending into the housing through the connector and being electrically connected with a connection row in the housing. Optionally, the connector includes fixing base and connecting seat, the fixing base sets up on the casing, and have the confession the pencil wears to establish first through-hole, the connecting seat detachably connect in the fixing base, and have the confession the pencil wears to establish the second through-hole. Optionally, one of the fixing base and the connecting base is provided with a first clamping piece, the other one of the fixing base and the connecting base is provided with a second clamping piece, and the first clamping piece is matched with the second clamping piece in a clamping way. Optionally, the first clamping piece is configured as a protruding portion, the second clamping piece is configured as a clamping groove, and the protruding portion is clamped in the clamping groove. Optionally, the protruding portion is located the fixing base, the connecting seat includes the cover to be located the sleeve portion of fixing base, set up logical groove on the sleeve portion, logical groove structure is for the draw-in groove. Optionally, the protruding portion has a first side and a second side that are disposed opposite to each other, the first side is closer to the housing than the second side, the first side abuts against an inner wall surface of the clamping groove, and the protruding portion further has a guiding inclined surface, and a height of the guiding inclined surface on the first side is higher than a height of the guiding inclined surface on the second side. Optionally, a first mounting hole is formed in the housing, a fixing ring is further arranged on the outer side of the housing, the fixing ring is provided with a second mounting hole communicated with the first mounting hole, and the connector is partially arranged in the fixing ring. Optionally, one end of the wire harness is connected with the connection row, and the other end of the wire harness is connected with an electric drive or a battery pack or an oil pump. According to a second aspect of the present disclosure, there is provided a battery pack including the high voltage distribution box as described above. According to a third aspect of the present disclosure, there is provided a vehicle including the battery pack as described above. Through above-mentioned technical scheme, when needs are with the connection row electrical connection in pencil and the casing in order to realize power transmission and/or signal transmission, stretch into the casing through the pencil through the connector in to the terminal of pencil is connected with the connection row in the casing, because the connector is fixed in the casing, the connector can support and fix the pencil of wearing to establish, in order to avoid the pencil to take place to rock and produce the influence to the connection between pencil and the connection row.
