Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

Fig. 1 is the utility model discloses overlook the structure schematic diagram, fig. 2 is the utility model discloses a look sideways at section structure schematic diagram, fig. 3 are the utility model discloses a socket fixed connection section's structure schematic diagram.

Referring to fig. 1 to 3, the utility model provides a distribution control equipment's fuse-base, include: fixed block 2, locating plate 4 and connecting block 6.

And the fixed block 2 is fixed at the upper end and the lower end of the base shell 1. The lower end of the fixed block 2 is fixed with the bottom of the base shell 1 through a screw 22.

And the positioning plate 4 is connected to the surface of the base shell 1. The lower end of the positioning plate 4 is provided with a socket 3. The positioning plate 4 is fixed on the upper surface of the base shell 1 in axial symmetry.

And the connecting block 6 is welded on the left side surface of the base shell 1. The right side of the base housing 1 is provided with a groove 62. The connecting block 6 is matched with the groove 62.

Because the installation plug that the fuse is more leads to fixed socket to take place not hard up, influences fuse and current conducting plate normal contact, leads to the unable normal work of fuse. Therefore, the utility model discloses a distribution control equipment's fuse-base utilizes locating plate and wiring bolt to fix the socket firmly inside base shell, and the locating plate prevents that wiring bolt from receiving to drag the emergence not hard up, droing, guarantees normal contact, the use of fuse, and the detachability of fixed block can be changed when being convenient for fix the insecure base shell, and connecting block and recess are convenient for connect a plurality of fuse-base shells.

The lower end of the base shell 1 protrudes inwards. The lower end of the fixed block 2 is provided with two support legs, and the two support legs are fixed with the base shell 1 through screws 22. The middle part of the fixed block 2 is provided with a threaded hole 21.

Fixed block 2 passes through screw 22 to be fixed in base shell 1 bellying, and the fixed block 2 of being convenient for can dismantle, fix, and when the fixed block 2 of being convenient for damaged, change fixed block 2, save the cost.
