Technical Field

[0001] The invention relates to the technical field of new energy vehicles, and in particular to an epoxy resin vulcanized insulated busbar for a high-voltage distribution box of a new energy vehicle. Background Art

[0002] The busbar is a conductor that connects the current-carrying branch circuits in the electrical device. It is a carrier for collecting and distributing electricity, also known as a busbar. It is customary to refer to the conductors of the current-carrying branch circuits in each distribution unit as busbars. The function of the busbar is to collect, distribute and transmit electric energy. Since the busbar has huge electric energy passing through it during operation, it will be subjected to great heat and electrodynamic effects when short-circuited. Therefore, the busbar material, cross-sectional shape and cross-sectional area must be reasonably selected to meet the requirements of safe and economical operation.

[0003] The high-voltage power distribution cabinet (box / box) for new energy electric vehicles is a high-voltage and high-current distribution unit PDU for all pure electric vehicles and plug-in hybrid electric vehicles. It adopts a centralized power distribution solution with a compact structure design, convenient wiring layout, and convenient and fast maintenance. According to the system architecture requirements of different customers, the high-voltage power distribution box also needs to integrate some battery management system intelligent control management units, thereby further simplifying the complexity of the power distribution of the vehicle system architecture.

[0004] The existing power distribution method in the high-voltage distribution cabinet of new energy electric vehicles is still the cable distribution line connection. This connection method requires multiple cables to connect multiple electrical parts on the electric vehicle, which results in the need for multiple connection holes between the high-voltage distribution cabinet, increasing space occupancy. At the same time, the cable is used in a smaller environment. In hot weather, the surface sheath of the cable is prone to aging, causing skin breakage, and in severe cases, it is easy to cause a short circuit between the cables, resulting in safety accidents. Summary of the invention

[0005] The purpose of the present invention is to provide an epoxy resin vulcanized insulated busbar for a high-voltage distribution box of a new energy vehicle, so as to solve the problem proposed in the above background technology that the existing high-voltage distribution cabinets used in new energy vehicles are easily connected by cables and may cause safety accidents.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an epoxy resin vulcanized insulated busbar of a high-voltage distribution box for a new energy vehicle, comprising a bushing, a jack, a copper plate, a sealing head, a positioning tube, a connecting plate, a slot and a positioning hole, wherein the inner wall of the bushing is connected to two copper plates, the jack is opened on the outer wall of the bushing, the sealing head is installed at the left end of the copper plate, the positioning tube is installed on the right side of the outer wall of the copper plate, and the positioning hole is opened on the bushing and the copper plate.

[0007] Preferably, the sealing head and the positioning tube are both installed with connecting plates, and the sealing head and the positioning tube are both provided with two slots, and the slots on the positioning tube are through-opened on the side wall of the positioning tube.

[0008] Preferably, the jack is opened at the gap between the two copper plates and the sleeve connection.

[0009] Preferably, the sleeve, sealing head and positioning tube are all epoxy resin tubes.

[0010] Preferably, an insulating tube is installed on the inner wall of the positioning hole on the copper plate, and the insulating tube is connected to the sleeve.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: through the setting of the epoxy resin vulcanized insulated busbar of the high-voltage distribution box of the new energy vehicle, the structural design is reasonable. The distribution method in the existing high-voltage distribution cabinet of the new energy electric vehicle is still the cable distribution line connection. This connection method requires multiple cables to connect multiple electrical parts on the electric vehicle, which results in the need for multiple connection holes to connect with the high-voltage distribution cabinet, increasing the space occupancy. At the same time, the cable is used in a smaller environment. In hot weather, the surface sheath of the cable is prone to aging, causing skin breakage. In severe cases, it is easy to cause a short circuit between the cables, causing a safety accident. In the present application document, a busbar is formed by a sheath made of epoxy resin material on the outer walls of two copper plates. Due to the characteristics of epoxy resin, the high temperature resistance and aging resistance of the copper plate are improved, and the sealing of the busbar terminal is improved, thereby improving the safety of the busbar in new energy vehicles.
