Description

TECHNICAL FIELD

[0001] The utility model relates to a power distribution box with built-in plastic crimping terminal, which is used for high-power power supply input, transmission and load protection on an aircraft and belongs to the technical field of aviation electrical connection components. BACKGROUND

[0002] There are many power distribution boxes for high-power power supply input, transmission and protection in the prior art, and the load external terminal used in the power distribution box is a splicing component, which has a large structure size, a large weight, low mechanical strength, a long assembly time and inconvenient maintenance. CONTENT OF THE UTILITY MODEL

[0003] The utility model solves the technical problem that the load external terminal used in the power distribution box in the prior art has a large structure size, a large weight, low mechanical strength, a long assembly time and inconvenient maintenance.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme:

[0005] A power distribution box with built-in plastic crimping terminal, comprising a protective plate, a spring loose non-removal screw, a terminal, a threaded hole bushing and a base;

[0006] The protective plate is provided with a spring loose non-removal screw; and the protective plate is connected with the base through the spring loose non-removal screw;

[0007] The terminal is arranged between the protective plate and the base;

[0008] The threaded hole bushing is embedded in the interior of the base.

[0009] The beneficial effects of the above technical scheme are as follows:

[0010] 1. In the utility model, the terminal is combined, the terminal assembly is divided by the joint of the protective plate and the base, the protective plate can be directly removed to connect external equipment, the structure size of the external terminal assembly is reduced by 30% compared with the splicing terminal assembly, the weight of the terminal assembly is reduced by about 10% compared with the terminal assembly composed of the same structure material, the terminal structure is integrally formed by plastic crimping, the mechanical strength is better than that of the splicing terminal, the structure not only meets the mechanical strength requirement, but also occupies less space and meets the weight limit requirement, error prevention is designed on the terminal assembly according to the actual use, and the user can use it conveniently.

[0011] 2. The utility model has higher installation integration, simple and reliable maintenance, shorter assembly time, beautiful appearance and regular structure compared with the splicing terminal body structure. DRAWING EXPLANATION

[0012] Figure 1 It is a structural schematic view of the utility model.

[0013] Figure 2 As Figure 1 is a top view.

[0014] Figure 3 As Figure 2 is a sectional view of A-A in the figure.

[0015] Figure 4 As Figure 2 is a sectional view of B-B in the figure.

[0016] In the figure: 1 - protective plate, 2 - spring loose non-removable screw, 3 - terminal post, 4 - threaded hole bushing, 5 - base. DETAILED DESCRIPTION

[0017] The utility model will be further described in connection with the drawings:

[0018] As Figure 1 shown, a power distribution box with built-in plastic terminal post, including protective plate 1, spring loose non-removable screw 2, terminal post 3, threaded hole bushing 4 and base 5;

[0019] The protective plate 1 is provided with spring loose non-removable screw 2;

[0020] The terminal post 3 is located between the protective plate 1 and the base 5, and the terminal post 3 is combined, and the terminal post 3 assembly takes the cooperation place of the protective plate 1 and the base 5 as the boundary line, can directly remove the protective plate 1 and connect external equipment;Compared with the external terminal post assembly structure, the volume is reduced by 30%, and the weight is lighter than the terminal post assembly structure of the same structural material composition by about 10%, and the terminal post 3 structure is integrally plastic pressure, and the mechanical strength is superior to the splicing type terminal post;

[0021] The threaded hole bushing 4 is embedded in the inside of the base 5;Through the screw and the threaded hole bushing 4, the mechanical connection is carried out with the aircraft equipment cabin.
