Abstract

The invention discloses a fuse protector base seat of a direct-current low-voltage fuse link. The fuse protector base seat comprises a base, a wire inlet end current-conducting plate, a wire outlet end current-conducting plate, a pair of sockets, a wire inlet end terminal stud and a wire outlet end terminal stud. A groove used for containing the fuse link is arranged in the center of the base. The wire inlet end current-conducting plate and the wire outlet end current-conducting plate are fixed at two ends of the base in a one-to-one corresponding mode. The pair of sockets are fixed on the inner side of the wire inlet end current-conducting plate and the inner side of the wire outlet end current-conducting plate in a one-to-one corresponding mode. The wire inlet end terminal stud and the wire outlet end terminal stud are installed on the outer side of the wire inlet end current-conducting plate and the outer side of the wire outlet end current-conducting plate in a one-to-one corresponding mode. The edge of one side of the wire inlet end current-conducting plate is further provided with a signal contact. According to the fuse protector base seat, electrical performance of the fuse link is improved, a knife contact fuse link with an indicating device or a knife contact fuse link without an indicating device can be loaded on the fuse protector base seat, and by connecting the fuse link with the signal contact, a user can connect the fuse link to a secondary circuit directly to determine whether the fuse link is fused.

Description

technical field [0001] The invention relates to a fuse base of a DC low-voltage fuse. Background technique [0002] The fuse base on the knife-type contact fuse-link can only be used as a matching current-carrying fuse-link installation. Usually the fuse is equipped with a fuse indicating device, which is convenient for users to use. Or for a fuse without a fuse indicating device, a fuse indicating device is usually connected in parallel outside the fuse, and when the fuse is blown, the fuse indicating device will be activated to notify the user to replace the fuse. However, if the fuse indicating device fails and does not operate, the user cannot clearly know whether the fuse is blown, which will cause safety problems. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a fuse base for DC low-voltage fuses, which can be loaded with fuses with indicating devices or fuses without indicating ...
