Title:
DIRECT CURRENT CONTACTOR AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/258895
Kind Code:
A1
Abstract:
A direct current contactor and a vehicle. The direct current contactor comprises a housing and two contact assemblies provided in the housing, each contact assembly comprising two connected moving contacts and two stationary contacts, and further comprises a driving system for driving the moving contacts to move towards or away from the stationary contacts so as to connect/disconnect the moving contacts and the stationary contacts; an arc extinguishing cavity is provided inside the housing, and the interior of the arc extinguishing cavity is divided into a first arc extinguishing chamber and a second arc extinguishing chamber by means of a first spacer; the contact assemblies are respectively located in the first arc extinguishing chamber and the second arc extinguishing chamber. Thus, the two contact assemblies are integrated into the two arc extinguishing chambers of one arc extinguishing cavity, and the on-off driving is performed in a single driving system mode, thereby simplifying the structure of the direct current contact. Moreover, on-off requirements of positive and negative electrode circuits can be satisfied by using one direct current contact, without mounting one contactor on each of the positive and negative electrodes, so that the size of a charging device is reduced and manufacturing costs are reduced.
