Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an installation structure of an electric vehicle distribution fuse. Background Technique

[0002] The main function of the automobile insurance device is that when the current flowing through the circuit exceeds the specified excessive current, the automobile circuit insurance device can cut off the circuit, thereby preventing the circuit connection wires and electrical equipment from being burned out, and limiting the fault within the smallest range. The insurance devices on the automobile mainly include fuses, fusible links and circuit breakers.

[0003] At present, the most widely used electric vehicle distribution fuse adopts a flat layout, and the contactor and the fuse are connected by a cable. The production process of the cable connection is complex and prone to errors; for the convenience of maintenance, the fuse is also arranged close to the upper cover of the chassis. Due to the shielding of the fuse, the space below the fuse cannot be utilized, wasting the vertical space. Also, because the flat layout of the fuse occupies a large horizontal space, the chassis is large, reducing the module power density; the flat layout of the fuse makes the maintenance window need to be directly above the chassis cover, and the overall vehicle layout needs to reserve space above the module for convenient maintenance operations, wasting the overall vehicle layout space.
