Problems solved by technology

[0002] At present, DC contactors and fuses are configured separately in the application process, but this will not only occupy a large installation space, but also require very high matching between DC contactors and fuses. If the matching degree is not good, it will affect the operation security of the entire application system

Abstract

The invention discloses a direct-current contactor with a fuse protection function. The direct-current contactor comprises a shell, two fixed contacts and two movable contacts, wherein the two movablecontacts are electrically connected and are arranged correspondingly opposite to the two fixed contacts in a vertical direction respectively; the two movable contacts can also be correspondingly connected with or disconnected from the two fixed contacts respectively; a fuse protection component capable of protecting the direct-current contactor is also arranged in the shell; the fuse protection component comprises a first component and a second component; the first component is provided with a first conductive part positioned on a fixed contact and sleeves a fixed contact, a first wiring partserving as an electrical input end, and a fuse body connected between the first conductive part and the first wiring part; the second component is provided with a second conductive part which is positioned on the other fixed contact and sleeves the other fixed contact, and a second wiring part connected with the second conductive part and serving as an electrical output end. The direct-current contactor has the advantages of functional integration, high operation safety, saving of the mounting space and the like.

Description

technical field [0001] The invention relates to the technical field of DC contactors, and specifically provides a DC contactor with a fuse protection function. Background technique [0002] At present, DC contactors and fuses are configured separately during application, but this will not only occupy a large installation space, but also require a very high degree of matching between DC contactors and fuses. If the matching degree is not good, it will affect the operation security of the entire application system. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] In order to overcome the above defects, the present invention provides a DC contactor with a fuse protection function, which has the advantages of integrated functions, high operating safety, and saving installation space. [0005] The technical solution adopted by the present invention in order to solve the technical problem is: a DC contactor with a fuse protection ...
