Description

Technical Field

[0001] The utility model relates to the technical field of automobile electrical appliance fuses, in particular to an automobile fuse box main body. Background Art

[0002] The car fuse box is mainly used to install car fuses to protect the various electrical components of the car. According to the different car system architectures of different customers, the main structure of the car fuse box also shows a certain degree of differentiation.

[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. The fuse box is a rectangular structure, with an external relay on one side of the fuse box, and cylinders for installation and positioning are respectively provided on the other three sides. The fuse box panel is provided with a mini fuse slot, a plug-in slow-blow fuse slot, a micro relay slot, a mini relay slot, a spare fuse slot and a short-circuiter. The main structure of the fuse box under this patented technology is relatively large, and because of the problem that the circuit breaker is easily detached due to vibration during use, secondary protection is required through limiters, such as Figure 1 As shown, it is difficult to meet the requirements of current automobile manufacturing customers for compact structure and convenient maintenance.

[0026] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0027] Example 1

[0028] This embodiment provides a car fuse box body, such as Figure 2-5 As shown, it mainly includes a fuse box body 100 and a first terminal plugging area 200 located in the fuse box body 100. 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. The first terminal plugging area 200 is integrally formed in the fuse box body 100 for installing the wiring terminal.

[0029] 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 220 is mainly composed of a plurality of single-terminal slots 211 arranged side by side, and the single-terminal slot 211 is used for plugging and installing a single terminal. 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 of the wiring terminal inserted below the single terminal slot 211 can enter above the support plate 320 and sit on the support plate 320.

[0030] The dual-terminal socket 220 is mainly composed of a plurality of dual-terminal slots 221 arranged side by side. The orthographic projection of the dual-terminal slots 221 is a Japanese-shaped structure, including two slots for accommodating plug-in terminals. Two groups of terminal supports 300 are arranged in the dual-terminal slots 211. 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 slots 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 is seated on the support plate 320 through the support plate 320.

[0031] 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 partition 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 partition 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 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 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.

[0032] The working principle of the automobile fuse box body provided in this embodiment is as follows: the wiring terminal to be plugged in is inserted from the bottom of the two slots of the slot group 500, and the top of the wiring 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 load-bearing column 310 and the connection point of the slot as the fulcrum, so that the upper plug-in part of the wiring terminal moves to the top of the support plate 320 and sits on the support plate 320, and the lower connecting part of the wiring 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 partition 400 or the double-terminal slot 221 and the partition 400, forming an effective limit for the connection terminal in the horizontal direction, thereby omitting the limiter used for horizontally limiting the connection terminal in the prior art. Moreover, since the 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 connection terminals is as close as possible to the thickness of the partition 400, thereby maximizing the structural compactness of the first terminal plug-in area, and enabling the size of the used miniature fuse (miniature fuse) to be further reduced, 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.

[0033] Example 2

[0034] 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:

[0035] like Figure 2-5 As shown, a limit plate 410 is integrally formed on the upper surface of the partition 400, and a plurality of limit plates 410 are arranged at intervals on the upper surface of each 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.

[0036] 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.

[0037] Example 3

[0038] 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:

[0039] like Figure 2-6 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 an OBD interface, which 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, and the two form a rectangular structure. Through reasonable structural arrangement, the compactness of the structure of the fuse box body 100 is improved.

[0040] The fuse box body 100 is also provided with a second terminal plug-in area 700, and the model of the fuse installed in the second terminal plug-in area 700 is different from that in the first terminal plug-in area. 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 orthographic projection is basically in the shape of a Japanese character through the second partition plate 720 arranged in the middle. At least one of the two slots of the second terminal slot 710 is provided with a terminal support 300, and the end face 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 wiring terminals plugged into the plurality of groups of second terminal slots 710 arranged side by side in the second terminal plug-in area 700 are of a conjoined structure, only one terminal support 300 can be arranged in one of the slots of some second terminal slots 710; when the wiring terminal plugged into the second terminal slot 710 is a single, one terminal support 300 is arranged in both slots of the second terminal slot 710. The terminal supports 300 connected in the second terminal slots 710 are all designed to be 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 connection terminals.
