Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

A fuse housing 1 with high mechanical strength as shown in fig. 1-2, comprises a housing 1 of an integrated structure and a base 2 arranged at the bottom of the housing 1 and fitted with the housing 1. The shell 1 is integrally rectangular and comprises an a side 7 and a b side 8, three clamping grooves 4 are formed in the lower side portion of the b side 8, and the clamping grooves 4 are communicated with the side wall of the shell 1 in a filling and stringing mode. Three card slots 4 symmetrical to the card slot 4 are also arranged on the side b 8 on the other side of the shell 1, namely six card slots 4 are arranged on the lower side part of the long side of the shell 1.

Furthermore, the base 2 is provided with six buckles 3 corresponding to the positions and the number of the clamping grooves 4 and a through groove 10 for accommodating the buckles 3, and the top of the buckle 3 is provided with a limiting part 9 facing outwards, namely a barb part. The side wall of the back of the buckle 3 is connected with the side wall of the through groove 10, namely the limiting part 9 is arranged towards the direction of the clamping groove 4. The limiting part 9 is a boss horizontally arranged outwards, and the volume of the boss is smaller than or equal to the volume of the through groove 10.

Further, be equipped with joint portion one 5 and be used for fixed binding post's joint portion two 6 on the base 2, be equipped with the current conducting plate 12 of connecting joint portion one 5 and joint portion two 6 between joint portion one 5 and the joint portion two 6, and be equipped with joint portion three 11 that is used for the joint fuse-element on the current conducting plate 12. The two ends of the conductive plate 12 are respectively disposed at the first clamping portion 5 and the second clamping portion 6, and the conductive plate 12 and the third clamping portion 11 are made of conductive materials.

Further, casing 1 pegs graft from top to bottom with base 2 for can accomplish casing 1's installation after buckle 3's boss joint to draw-in groove 4, compare in the casing 1 of structure about among the prior art, 1 mechanical strength of casing of this kind of structure is higher and more easy equipment production efficiency is higher.

It should be noted that the first connecting portion and the second connecting portion are not limited to only the locking slot 4 and the buckle 3, and may be a sliding slot or a pin connection as long as the split connection can be realized.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and do not limit the spirit and scope of the present invention. Various modifications and improvements of the technical solutions of the present invention may be made by those skilled in the art without departing from the design concept of the present invention, and the technical contents of the present invention are all described in the claims.
