[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] In a first aspect, this embodiment provides a fuse box.

[0034] Reference Figure 1 and Figure 5 , the fuse box provided by the utility model is now described. The automobile fuse box is a box for installing automobile fuses. According to the size of the installed fuse, it can be divided into: small automobile fuse box, medium automobile fuse box and large automobile fuse box. The fuse box provided in this embodiment includes a fuse box body 1, a locking piece 2 pre-installed inside the fuse box body 1, and a fixing mechanism 3 for connecting the locking piece 2 and the fuse box body 1. The locking piece 2 is an integrated type, and the shape of the locking piece 2 is adapted to the shape of the fuse box body 1. The fixing mechanism 3 is arranged between the locking piece 2 and the fuse box body 1, and is used to fix the locking piece 2 on the fuse box body 1.

[0035] Compared with the prior art, the fuse box provided by the utility model adopts an integrated locking piece 2. Before installing the terminal and the wiring harness, the integrated locking piece 2 is pre-installed on the fuse box body 1 through the fixing mechanism 3. When pre-installing the locking piece 2, since the locking piece 2 is integrated, only one side of the pre-installation operation is required, which reduces the number of operations and improves the pre-installation efficiency. After installing the terminal and the wiring harness, only one side of the integrated locking piece 2 needs to be fixed, which further improves the efficiency of installing the locking piece 2.

[0036] Optionally, the fuse box body 1 includes a bottom box 11 and a top shell 12 connected to the bottom box 11. The bottom box 11 and the top shell 12 are connected by a buckle structure. The top shell 12 is arranged above the bottom box 11. The buckle structures are arranged in four numbers and divided into two groups. The two groups of buckle structures are arranged on both sides of the top shell 12 and the bottom box 11, respectively. The buckle structure includes a buckle arranged on the outer wall of the top shell 12 and a locking platform arranged on the outer wall of the bottom box 11. A square through groove is arranged in the middle of the buckle, and the buckle extends downward. The side of the locking platform is a guiding inclined surface, and the side opposite to the locking platform and the buckle is a plane. When the top shell 12 and the bottom box 11 are fixed by the buckle structure, the buckle slides in the direction of the locking platform, and the guiding inclined surface gradually opens the buckle, causing the buckle to undergo elastic deformation, and the buckle gradually enters the through groove. After the buckle completely enters the through groove, the buckle resets under the action of its own elastic force, and at this time the locking platform completely enters the through groove, and the buckle is engaged with the locking platform. The top shell 12 and the bottom box 11 are both made of plastic, wherein the top shell 12 and the buckle are integrally formed by injection molding, and the bottom box 11 and the lock platform are integrally formed by injection molding.

[0037] Optionally, the fixing mechanism 3 includes two groups of first locking components 31, and the two groups of first locking components 31 are respectively arranged on both sides of the locking plate 2. The first locking components 31 are arranged on both sides of the locking plate 2, and the locking plate 2 can be fixed from both sides of the locking plate 2 at the same time, so that the locking plate 2 is fixed more stably. The locking plate 2 is arranged between the bottom box 11 and the top shell 12. When the locking plate 2 is pre-installed, the locking plate 2 moves in the direction from the top shell 12 to the bottom box 11. During the movement of the locking plate 2, the first locking component 31 locks and fixes the locking plate 2.

[0038] Optionally, the first locking assembly 31 includes a first claw 311 arranged on the inner wall of the fuse box body 1 and a second claw 312 arranged on the side of the locking plate 2.

During this process, the inclined surfaces of the first claw 311 and the second claw 312 gradually approach and contact each other, and then the first claw 311 and the second claw 312 slide relative to each other. Under the action of the inclined surfaces of the first claw 311 and the second claw 312, the side wall of the bottom box 11 is elastically deformed and bulges outward. After the first claw 311 and the second claw 312 are completely misaligned, the side wall of the bottom box 11 is reset, and the first claw 311 and the second claw 312 limit each other to prevent the locking plate 2 from detaching from the bottom box 11, thereby fixing the position of the locking plate 2 and completing the pre-installation.

During this process, the inclined surfaces of the first claw 311 and the second claw 312 gradually approach and contact each other, and then the first claw 311 and the second claw 312 slide relative to each other. Under the action of the inclined surfaces of the first claw 311 and the second claw 312, the side wall of the bottom box 11 is elastically deformed and bulges outward. After the first claw 311 and the second claw 312 are completely misaligned, the side wall of the bottom box 11 is reset, and the first claw 311 and the second claw 312 limit each other to prevent the locking plate 2 from detaching from the bottom box 11, thereby fixing the position of the locking plate 2 and completing the pre-installation.
