The first arc portion 120 and the second arc portion 230 are used for providing a holding point for a user when the user installs the device, the user can conveniently hold the base 100 or the upper cover 200 by the hand when operating, and the holding point is abutted on the first arc portion 120 and the second arc portion 230, so that force can be conveniently applied, and the installation is easier.

In some embodiments, as shown in fig. 1 to 7, the base 100 is a vulcanized rubber material member, and the cover 200 is a vulcanized rubber material member.

In the related art, most of the fuse holders are made of PVC, and the waterproof and dustproof grade of the PVC is IP65. The fuse holder is made of TPV (thermoplastic vulcanizate), namely vulcanized rubber, and the waterproof and dustproof registration of the base 100 and the upper cover 200 made of the TPV is IP67, so that the safety of the fuse holder is greatly improved.

In some embodiments, as shown in fig. 1 to 7, the fuse 300 includes a fastening portion 310, a first insertion portion 320 and a second insertion portion 330, the first insertion portion 320 and the second insertion portion 330 are spaced apart from each other at the bottom of the fastening portion 310, and the first insertion portion 320 and the second insertion portion 330 are respectively inserted into the two terminals 114.

In the embodiment of the present disclosure, the top of the fastening portion 310 contacts the sidewall of the second receiving groove 220 to increase the friction between the fuse 300 and the upper cover 200, thereby improving the connection stability of the fuse 300.

The foregoing is merely exemplary of the present application and is not intended to limit the present application in any manner. Those skilled in the art can now make numerous possible variations and modifications to the disclosed embodiments, or modify equivalent embodiments, using the methods and techniques disclosed above, without departing from the scope of the claimed embodiments.
