Description

Technical Field

[0001] The utility model relates to the technical field of vehicle power distribution and circuit protection, and particularly relates to an extended electrical box. Background Art

[0002] The electrical box appears with the development of vehicle electrical appliances, which is used to realize power switching and ensure vehicle safety through protection devices. The electrical box is a carrier for power transmission, which realizes the control of large current by small current through relays and realizes overvoltage and overcurrent protection of the circuit through fuses.

[0003] The front cabin electrical box is a general-purpose product. Due to the increasing automotive configurations, the existing number, types, and power levels of fuses on the front cabin electrical box do not meet the requirements.

[0004] The existing front cabin electrical box does not have enough space to add more fuses. As Figure 1 shown, except for two pairs of inline installed in the form of movable modules in the front cabin electrical box, other components are fixedly installed with the electrical box. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide an extended electrical box. On the basis of the existing electrical box, the configuration functions are increased, and the existing number, types, and power levels of fuses on the general-purpose front cabin electrical box do not meet the requirements of vehicle function configurations. When the electrical box works, a fuse block is used to protect the circuit.

[0006] The utility model is realized by the following technical solutions:

[0007] An extended electrical box, wherein two pairs of inline of the electrical box are arranged outside the box body and are connected to the vehicle electrical appliance wiring harness and the engine wiring harness; two fuse blocks are arranged inside the electrical box.

[0008] Further, each of the fuse blocks includes four fuses.

[0009] Further, one of the fuse blocks includes four mini fuses, and the other fuse block includes four MCASE fuses.

[0010] Preferably, the MCASE fuse is a plug-in circuit breaker.

[0011] Preferably, the mini fuse is a sheet circuit breaker.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] In a limited space, an extended electrical box was developed, and the original two pairs of wiring harnesses were arranged inline outside the electrical box. Two fuse blocks, including four mini and four MCASE, were arranged at the original position. In this way, eight fuses were added to the whole vehicle, which increased the types and quantity of fuses in disguise to meet the power distribution needs of the whole vehicle and thus meet the functional requirements of the project.

[0014] At the same time, it means that there is no need to open a new electrical box in the front cabin, saving the cost of each vehicle and shortening the development cycle. The principle of universalization of the electrical box in the front cabin is not broken, and there is no need to remodel the electrical box. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] Figure 2 An embodiment of an extended electrical box for implementing the utility model is shown, specifically a front cabin electrical box, wherein two pairs of inlines of the front cabin electrical box are arranged outside the box body (not shown) and are connected to the automotive electrical wiring harness and the engine wiring harness; two fuse blocks are arranged inside the front cabin electrical box.

[0023] Each of the fuse blocks includes 4 fuses. Furthermore, one of the fuse blocks includes 4 mini fuses, and another of the fuse blocks includes 4 MCASE fuses.

[0024] As another optional means, the MCASE fuse block is a plug-in circuit breaker. More preferably, the mini fuse is a sheet-shaped circuit breaker.

[0025] The extended electrical box of the utility model adds 8 fuses, which increases the types and quantity of fuses in disguise, solves the power level problem, and can meet the power distribution needs of the entire vehicle.

[0026] Figure 3 The utility model shows a circuit diagram of the connection between the fuse block and the power supply.
