Fig. 1 shows a specific embodiment of a fuse mounting base disclosed in the present invention, which includes: an upper base body 101 and a lower base body 102 detachably connected to each other, wherein the upper base body 101 and the lower base body 102 enclose a space for accommodating the fuse 200; the upper base 101 is provided with a side wall for shielding a conductive portion of the fuse 200, and an upper wall 1011 of the upper base 101 is provided with a mounting hole a. Wherein the conductive portion of the fuse 200 includes conductive surfaces 2011 on both sides of the body portion 201 of the fuse 200 and the connection terminal 202 of the fuse 200.

The fuse mounting seat 100 is configured as the upper seat body 101 and the lower seat body 102 which are detachably connected, and the upper seat body 101 is provided with the side wall which shields the conductive part of the fuse 200, so that the conductive part of the fuse 200 is located inside the mounting seat, and the situation that an operator touches the conductive part to cause electric shock when the fuse 200 is mounted or dismounted is avoided.

Specifically, the lower housing 102 has a rectangular parallelepiped structure as a whole, and the fuse 200 is mounted on an upper surface of the lower housing 102. The lower base 102 comprises a first mounting surface 1021 in the middle part and second mounting surfaces 1022 on two sides of the first mounting surface 1021; the height of the second mounting surface 1022 relative to the bottom surface is greater than the height of the first mounting surface 1021 relative to the bottom surface, since the main body portion 201 of the fuse 200 is generally cylindrical, and the connecting terminals 202 thereof are located on both sides of the end surface of the cylinder, the first mounting surface 1021 in the lower housing 102 is lower than the second mounting surface 1022, so that the main body portion 201 of the fuse 200 can be mounted on the first mounting surface 1021, and the connecting terminals 202 of the fuse 200 are mounted on the second mounting surface 1022.

The structure of the upper housing 101 is not exclusive, and in one embodiment, the upper housing 101 is a frame structure having a size approximately equal to the external size of the lower housing 102, and a mounting hole a is opened in an upper wall thereof, and the fuse 200 is inserted into the mounting hole a and mounted on the lower housing 102.

In another embodiment, as shown in fig. 1, two upper seat bodies 101 are provided, and the two upper seat bodies 101 are respectively connected to the two second mounting surfaces 1022 of the lower seat body 102. By providing two independent upper housing bodies 101, the main body 201 of the fuse 200 having the insulating layer is exposed outside the mounting base, which facilitates the operator to hold the fuse 200 from the main body 201 for mounting or dismounting.

Specifically, the upper housing 101 includes: two L-shaped bent walls 1012 that are provided to face each other, and a shielding wall 1013 and the upper wall 1011 that are connected between the two L-shaped bent walls 1012 and are parallel to both side end surfaces of the main body portion 201 of the fuse 200. The bottom walls of the L-shaped bent walls 1012 are respectively connected to the second mounting surfaces 1022 in a snap-fit manner, and the upper wall 1011, the L-shaped bent walls 1012, and the shielding walls 1013 are integrally formed. The L-shaped bent wall 1012 and the shielding wall 1013 shield the conductive portions of the fuse 200 from three directions, thereby preventing an operator from touching the conductive portions of the fuse 200.

Specifically, a gap is formed between the shielding wall 1013 and the upper surface of the lower housing 102. The copper bar 300 connected to the connection terminal 202 of the fuse 200 is passed out from the gap.

Specifically, in order to improve the strength of the upper housing 101, the upper housing 101 further includes a reinforcing wall connected between the upper wall 1011 and the L-shaped bent wall 1012 and parallel to the shielding wall 1013; the reinforcing walls comprise a first reinforcing wall 1014 and a second reinforcing wall 1015, the first reinforcing wall 1014 and the second reinforcing wall 1015 are triangular plate bodies, and the upper seat body 101 can form a frame structure with a better supporting structure and better strength by arranging the first reinforcing wall 1014 and the second reinforcing wall 1015.

Specifically, the mounting hole a is a notch formed in the upper wall 1011, and the aperture of the end close to the notch is smaller than the aperture of the middle portion, so as to avoid that an operator touches the conductive portion from the notch along the upper side of the fuse mounting seat 100 due to the excessive notch.

Fig. 2 and 3 show a specific embodiment of the installation structure of the fuse 200 of the present invention, which includes: a fuse 200 including a main body portion 201 and connection terminals 202 located on both sides of the main body portion 201; and the fuse mount 100, the fuse 200 being mounted on the fuse mount 100.

When the fuse 200 is mounted, the fuse 200 passes through the mounting hole a from the upper side of the upper housing 101 along the upper wall 1011 thereof and is mounted on the lower housing 102. The copper bar 300 connected with the fuse 200 is inserted into the gap and connected with the connection terminal 202.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
