The embodiment of the invention provides a direct-current (DC) contactor and a vehicle. The direct-current contactor comprises a shell and two groups of contact assemblies arranged in the shell, eachcontact assembly comprises two moving contacts and two static contacts, wherein the two moving contacts are connected. The DC contactor also comprises a driving system used for driving the moving contacts to move towards or away from the static contacts so as to realize on-off of the moving contacts and the static contacts, wherein the shell is internally provided with an arc extinguishing cavity;the arc extinguishing cavity is divided into a first arc extinguishing chamber and a second arc extinguishing chamber by a first blocking piece in the arc extinguishing cavity; the contact assembliesare respectively positioned in the first arc extinguishing chamber and the second arc extinguishing chamber; two groups of contact assemblies are integrated into two arc extinguishing chambers of onearc extinguishing cavity, the on-off driving is carried out in a single driving system mode, the structure of the direct-current contactor is simplified, the on-off requirements of positive and negative pole circuits can be met by using one direct current contactor, a contactor does not need to be installed on each of the positive and negative poles, the size of a charging device is reduced, andthe manufacturing cost is reduced.
本申请实施例提供一种直流接触器及车辆,该直流接触器包括壳体和设置在壳体内的两组触点组件,每组触点组件包括两个相连的动触头和两个静触头,还包括用于驱动动触头朝向靠近或远离静触头方向移动以实现动触头和静触头通断的驱动系统,其中壳体内具有灭弧腔体,灭弧腔体内的第一隔挡件将其分割成第一灭弧室和第二灭弧室,触点组件分别位于第一灭弧室和第二灭弧室内,即将两组触点组件集成到一个灭弧腔体的两个灭弧室内,并通过单一驱动系统的方式进行通断驱动,简化了直流接触器的结构,而且使用一个直流接触器就能够满足正负两极线路的通断需求,无需在正负两极各安装一个接触器,缩小了充电装置的体积并降低制造成本。
