[0003] At present, the structural settings of automobile fuse boxes are mainly divided into plug-in terminal type and hard-wired access type. The plug-in terminal type automobile fuse box mainly adopts the circuit board form of PCB board, which is to weld the relay connectors and the connectors such as combination switch and ignition switch together to form a wiring harness fuse box. This structural form meets the requirements of compact structure and small size, but once the internal plug board has a virtual connection or short circuit, the entire fuse box needs to be replaced, which is inconvenient to maintain and use.

[0004] The hard-wired car fuse box is mainly realized by setting multiple groups of slots for plugging in wiring terminals on the main structure. The wiring terminals of each electrical device are respectively placed in the corresponding slots, and then the fuses (also known as fuses) are plugged into the wiring terminals to achieve their main functions. For example, the patent publication number is CN203644719U, which discloses a hard-wired dashboard fuse box for automobiles.

[0038] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention. Example 1

[0039] This embodiment provides a car fuse box, such as Figure 2-11 As shown, the fuse box mainly includes a fuse box body 100, a terminal block 800 and a fuse 900. The fuse box body 100 is a rectangular structural frame, and a connecting structure is formed on its outer wall for connecting and fixing with the corresponding installation part of the car. A first terminal plugging area 200 is provided in the fuse box body 100, and the first terminal plugging area 200 is integrally formed in the fuse box body 100 for installing the terminal block.

[0040] The first terminal plug-in area 200 includes a single-terminal plug-in strip 210 and a double-terminal plug-in strip 220. The single-terminal plug-in strip 210 is mainly formed by arranging a plurality of single-terminal slots 211 in parallel, and the single-terminal slots 211 are used for plugging and installing a single terminal 800. A terminal support 300 is integrally formed in the single-terminal slot 211, and the terminal support 300 includes a bearing column 310 and a support plate 320, one end of the support plate 320 is connected to the upper part of the bearing column 310 to form a hook-shaped structure, and the lower part of the bearing column 310 is connected to the side wall of the single-terminal slot 211. After the terminal support 300 is connected to the single terminal slot 211, the end face 3201 of its support plate 320 faces the opposite side of the single terminal slot 211, and the terminal support 300 can rely on the connection point between the load-bearing column 310 and the single terminal slot 211 to rotate around a point a predetermined distance in the direction outside the slot, so that the upper plug-in portion 801 of the connecting terminal 800 inserted below the single terminal slot 211 can enter above the support plate 320 and sit on the support plate 320.

[0041] The dual-terminal socket 220 is mainly formed by arranging a plurality of dual-terminal slots 221 in parallel. The orthographic projection of the dual-terminal slots 221 is a Japanese-shaped structure, including two slots for accommodating the plug-in terminal 800. Two groups of terminal supports 300 are arranged in the dual-terminal slots 221. The two groups of terminal supports 300 share a load-bearing column 310. Two support plates 320 are connected to the shared load-bearing column 310 in a back-to-back manner to form a double-headed structure. The so-called back-to-back manner of the support plates 320 means that the end faces 3201 of the support plates 320 face opposite directions, and the shared load-bearing column 310 is connected to the middle support plate of the dual-terminal slot 221. There is a predetermined gap between the two support plates 320 connected to the shared load-bearing column 310 to allow the two support plates 320 to rotate to a certain extent in a manner close to each other, so that the terminal 800 passes through and sits on the support plate 320.

[0042] The arrangement of the single-terminal plug-in strip 210 and the double-terminal plug-in strip 220 in the first terminal plug-in area 200 is as follows: the single-terminal plug-in strip 210 is located at the two side edges of the area, and at least one row of double-terminal plug-in strips 220 is arranged in the two side edges. When the double-terminal plug-in strip 220 is in a single row, the single-terminal plug-in strip 210 and the double-terminal plug-in strip 220 on both sides share a first partition plate 400, and when the double-terminal plug-in strip 220 is in multiple rows, the single-terminal plug-in strip 210 and the double-terminal plug-in strip 220 and the double-terminal plug-in strips 220 also share a first partition plate 400. After the single-terminal plug-in strip 210 and the double-terminal plug-in strip 220 are arranged, the single-terminal slots 211 and the double-terminal slots 221 and the double-terminal slots 221 correspond to each other in the longitudinal direction, and the so-called longitudinal direction here refers to the direction relative to the horizontal arrangement of the single-terminal plug-in strip 210 or the double-terminal plug-in strip 220. After the single-terminal socket 210 and the double-terminal socket 220 are arranged, the terminal slots located on both sides of the first partition 400 are grouped as a slot group 500, that is, the two slots of the slot group 500 are the single-terminal slot 211 and one of the double-terminal slots 221 adjacent thereto, and two slots adjacent to the two double-terminal slots 221. The end faces 3201 of the support plates 320 of the terminal supports 300 in the two slots of the slot group 500 are both facing each other toward the first partition 400. The two slots of the slot group 500 are used to plug in two matching wiring terminals, and the so-called matching two wiring terminals refer to two wiring terminals that form a circuit and are plugged in the same fuse to form protection for the electrical circuit.

[0043] The main structure of the terminal block 800 includes an upper plug-in portion 801 and a lower wiring portion 802. The top of the upper plug-in portion 801 is provided with a plug-in hole for the plug pin of the fuse 900 to be inserted and achieve interference fit. The lower wiring portion 802 includes a leg for wrapping the wiring harness. Depending on the type of the terminal block 800, the terminal block 800 includes a first terminal block 810. The fuse 900 includes a first fuse 910 according to the different models of the terminal block 800. The first terminal block 810 is plugged into the corresponding single-terminal slot 211 and double-terminal slot 221 in the first terminal plug-in area 200, and the first fuse 910 is plugged into the matching first terminal block 810. In this embodiment, the first terminal block 810 is formed into a first terminal row 811 by an integrated molding method, and the first terminal row 811 can be installed in the slot as a whole, which can improve the installation efficiency.

[0044] The working principle of the automobile fuse box provided in this embodiment is as follows: the first terminal 810 is inserted from the bottom of the two slots of the slot group 500, and the top of the terminal supports the lower surface of the support plate 320 located in the slot, so that the terminal support 300 rotates a predetermined distance out of the slot with the connection point between the load-bearing column 310 and the slot as the fulcrum, so that the upper plug-in portion of the terminal moves to the top of the support plate 320 and sits on the support plate 320, and the lower connecting portion of the terminal is located below the support plate 320. After the connection terminal is plugged in, it is located in a closed space surrounded by the single-terminal slot 211 and the first partition 400 or the double-terminal slot 221 and the first partition 400, forming an effective limit for the first terminal 810 in the horizontal direction, thereby omitting the limiter used for horizontally limiting the connection terminal in the prior art. Moreover, since the first partition 400 forms a physical isolation for the two connection terminals located in the slot group 500, and the end faces of the support plates 320 of the two terminal supports 300 located in the slot group 500 are arranged face to face, the distance between the two first connection terminals 810 is as close as possible to the thickness of the first partition 400, thereby maximizing the structural compactness of the first terminal plug-in area, and further reducing the size of the used miniature fuse (miniature fuse), thereby greatly reducing the volume of the fuse box body, and achieving the convergence of the volume of the plug-in type fuse box and the plug-in terminal type fuse box using a PCB board, which significantly saves manufacturing costs while also reducing maintenance costs. Example 2

[0045] This embodiment 2 is formed on the basis of embodiment 1, and by forming a limit plate on the partition and an anti-touch protrusion on the slot row, the stability of the fuse after installation can be effectively improved, and the safety of the fuse box can be effectively improved. Specifically:

[0046] like Figure 4-7 As shown, a limit plate 410 is integrally formed on the upper surface of the first partition 400, and a plurality of limit plates 410 are arranged at intervals on the upper surface of each first partition 400, and each limit plate 410 is located between two slot groups 500. After the fuse is plugged into the two wiring terminals in the slot group 500, the two side surfaces of the limit plate 410 contact the side surfaces of the fuse, which plays a role in limiting the fuse, can prevent the fuse from tilting sideways due to external force, and can improve the stability of the fuse after plugging.

[0047] A first protrusion 212 is formed by extending upward on the outer surface of the single-terminal socket 210. The first protrusion 212 can be arranged at intervals or in a continuous bow-shaped design. A second protrusion 222 is formed by extending upward on the middle beam of the dual-terminal socket 220. The second protrusion 222 is arranged at intervals and is located between two dual-terminal slots 221. The second protrusion 222 is a column structure. To reduce weight, the second protrusion 222 is a hollow column. The upper surfaces of the first protrusion 212 and the second protrusion 222 have the same horizontal height, that is, the upper surfaces of the first protrusion 212 and the second protrusion 222 are arranged flush on the horizontal plane, and the height of the upper surface of the installed fuse does not exceed the height of the upper surface of the first protrusion 212, thereby providing effective anti-touch protection for the installed fuse. Example 3

[0048] This embodiment 3 is formed on the basis of embodiment 1 or embodiment 2, and by providing a second terminal plug-in area and / or an OBD interface area on the fuse box body, the integration of the fuse box body is improved, and the installation space of automobile parts is further saved. Specifically:

[0049] like Figure 4-7 As shown, the fuse box body 100 is also provided with an OBD interface area 600, which is a groove structure for accommodating and installing the OBD interface 1000. The so-called OBD interface is the abbreviation of the international standard automobile communication interface. At this time, the arrangement shape of the first terminal plug-in area 200 in the fuse box body 100 is L-shaped as a whole, and the OBD interface area 600 is located in the corner area of ​​the first terminal plug-in area 200. The two form a rectangular structure. Through reasonable structural arrangement, the compactness of the structure of the fuse box body 100 is improved.

[0050] The fuse box body 100 is also provided with a second terminal plug-in area 700, and the type of the fuse installed in the second terminal plug-in area 700 is different from that in the first terminal plug-in area 200. The second terminal plug-in area 700 includes a plurality of groups of second terminal slots 710, and the second terminal slots 710 are arranged side by side and spaced apart. The second terminal slots 710 form a double slot structure whose positive projection is basically in the shape of a Japanese character through the second partition plate 720 arranged in the middle. The wiring terminal 800 also includes a second wiring terminal 820, and the fuse 900 also includes a second fuse 920. The second wiring terminal 820 is plugged into the second terminal slot 710 of the second terminal plug-in area 700, and the second fuse 920 is plugged into the second wiring terminal 820 that matches. At least one of the two slots of the second terminal slot 710 is provided with a terminal support 300, and the end surface 3201 of the support plate 320 of the terminal support 300 installed in the second terminal slot 710 faces the second partition plate 720 in the middle. When the second wiring terminals 820 inserted into the plurality of second terminal slots 710 arranged side by side in the second terminal plug-in area 700 are of a conjoined structure, that is, the second wiring terminals 820 form a second wiring terminal row 821 by an integrated molding method, only one terminal support 300 can be set in one of the slots in some second terminal slots 710, further improving the installation efficiency; when the second wiring terminal 820 inserted into the second terminal slot 710 is a single one, one terminal support 300 is set in both slots in the second terminal slot 710. The terminal supports 300 connected in the second terminal slots 710 are all designed face to face, and a partition is provided in the middle, which also has the technical effect of being able to reduce the distance between the wiring terminals. Example 4

[0051] This embodiment 4 is formed on the basis of any one of the embodiments 1-3, and through the adaptive optimization design of the wiring terminal and the terminal slot structure, a limit is formed in the vertical direction after the wiring terminal is inserted into the terminal slot, and a full range of limit is formed for the wiring terminal as a whole, thereby ensuring the stability of the wiring terminal and improving the safety of the automobile fuse box. Specifically;

[0052] like Figure 2-11As shown, a guide limit leg 803 is provided in the main structure of the terminal block 800, and a limit protrusion 230 is formed in the single terminal slot 211, the double terminal slot 221 and the second terminal slot 710. The limit protrusion 230 is a prism protrusion attached to the inner wall and extending into the terminal slot by a predetermined length. For example, when the first terminal block 810 is inserted into the single terminal slot 211, the upper plug-in portion 801 is located on the upper surface of the support plate 320. At this time, the upper surface of the guide limit leg 803 is in contact with the lower surface of the limit protrusion 230, which is used to limit the first terminal block 810 from moving upward. At this time, after the first terminal block 810 is inserted into the single terminal slot 211, the front, back, left and right directions are respectively limited by four plate surfaces, and the upper and lower directions are respectively limited by the support plate 320 and the limit protrusion 230, thereby ensuring the stability of the terminal block after installation. Because the terminal block is made of metal sheets such as copper, the guide limit leg 803 can be bent, which basically does not affect the removal after damage.
