Power connection box for hybrid vehicles

Abstract

A power connection box for a hybrid vehicle is disclosed. The power connection box includes: a current supply part for supplying a constant current to the inverter and including first and second main relays and a pre-charging relay between the first main relay and the bus bar; and a wire installation part, the wire installation part includes a plurality of wires installed at opposite sides of the body and connected to the first and second main relays and the pre-charging relay to supply operating power to the first and second main relays and Precharge relay. Prevents wires from becoming tangled or damaged due to friction between them. The wire is inserted into the terminal connection port of the printed circuit pattern having the circuit pattern, so that the wire is simply disconnected from or connected to the printed circuit board.

Description

technical field [0001] The invention relates to a power connection box (power connection box). More particularly, the present invention relates to an electric power connection box for a hybrid vehicle, which is installed in the hybrid vehicle to receive and transmit high current into the hybrid vehicle, and is configured to facilitate Ease of maintenance so that the section and the multiple wires associated with the section can be safely connected and disconnected from the electrical connection box. Background technique [0002] A hybrid vehicle uses at least two power sources as drive sources. A hybrid vehicle refers to a next-generation vehicle that exhibits improved fuel efficiency and significantly reduces harmful gas emissions as compared to prior art vehicles by significantly reducing its body weight to minimize air resistance . [0003] In detail, a hybrid vehicle is generally implemented in such a manner that the hybrid vehicle uses both a prior art internal combu...

Problems solved by technology

However, when the wires are pulled out from the part, the wires get tangled so that the wires rub together causing damage to each other

[0014] Furthermore, when trying to perform maintenance on the power connection box, since the wires are irregularly tangled together, the power connection box cannot be maintained without interference between the wires and peripheral parts

[0015] Specifically, the process of disconnecting the wire from the part, performing maintenance on the wire, and connecting the wire to the part is complex

In addition, in the process of disconnecting the wire from the part or reconnecting the wire to the part, the wire may be damaged, or a connection failure to the wire may be caused
