Background technique

For aircraft fire protection demand for security, firewall is set at engine nacelle hanging structure.Consider maintainability and safety Property require, electrical system usually need to firewall be arranged parting surface.In Aircraft Electrical System, patch board device is for electricity One important component of line docking, the current country, which lacks, docks device suitable for the high-power electric wire of firewall.

Summary of the invention

The purpose of the present invention is: a kind of high-power electric wire buttcover plate for firewall is designed, in order to solve on firewall The docking of high-power electric wire prevents foreign matter from falling into.

To solve this technical problem, the technical scheme is that

A kind of high-power electric wire buttcover plate for firewall, the high-power electric wire buttcover plate for firewall, It include: the first support 1, the second support 2, binding post 3;First support 1 is by angular lug-mounted 12, main body 11, rectangular Lug-mounted 13 forms;For the assembly that misplaces, angular lug-mounted 12 and rectangular lug-mounted 13 are located at each support The top and bottom of two sides;

The main body 11 is the cuboid with several semicircle card slots, and the both side ends in main body 11 in card slot are added The radius of " arch " connected in star, " arch " connected in star is adapted with the radius of 3 contact surface of binding post, and the depth of groove slightly below contacts The thickness in face;Partition is stretched out in the direction perpendicular to main body between two card slots, the face and semicircular circle core shaft where partition Line is parallel;The distance between the thickness of main body 11 and 3 two contact surfaces of binding post are adapted;After assembling, the height of partition is omited Higher than the height of the end face of binding post 3.

Preferably, the angular lug-mounted 12 is the triangular piece of one mounting hole of band;The rectangular mounting ear Piece 13 is the rectangular pieces of two mounting holes of band, in order to which two support dislocation are fixed, and open peace less as far as possible on firewall Fill hole.

Preferably, the high-power electric wire buttcover plate for firewall further includes protective cover 4, the protective cover 4 It is divided into upper cover and lower cover, both ends have installation sheet, and the installation sheet is adapted with the angular lug-mounted 12 of support, protective cover Depth be adapted with the height of 11 partition of main body.

The material of the protective cover 4 is fiberglass reinforced phenoplasts insulating materials.

The material of first support 1 is fiberglass reinforced phenoplasts insulating materials.

The material of second support 2 is fiberglass reinforced phenoplasts insulating materials.

The beneficial effects of the present invention are: the present invention proposes a kind of buttcover plate of electric wire high-power on firewall, pass through Support and protective cover can be such that terminal plate is directly installed in structure, and the size and number of binding post can according to the actual situation more Change, the connecting terminal of electric wire contacts reliably between each other, and selected materials are common insulating materials and standard component, manufacturing process Simply, cost is relatively low, has biggish application value.And by protective cover and support, understructure concave-convex design, reduce with Structure mounting hole is conducive to the fire proof seal requirement on firewall.

Detailed description of the invention

Fig. 1 be buttcover plate of the invention combination diagram and use schematic diagram;

Fig. 2 is that buttcover plate of the invention dismantles rear structural schematic diagram;

Fig. 3 is the schematic diagram of the support of buttcover plate of the invention;

Fig. 4 is that buttcover plate of the invention removes the top view after protective cover;

Fig. 5 is the sectional view of the line A-A along Fig. 4;

In figure, the first support of 1-, the second support of 2-, 3- binding post, 4- protective cover, 11- main body, the angular lug-mounted of 12-, The rectangular lug-mounted of 13-.

Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples:

Referring to Fig. 1 and Fig. 2, the high-power electric wire buttcover plate for firewall of the invention, it is described for firewall High-power electric wire buttcover plate, comprising: the first support 1, the second support 2, binding post 3, protective cover 4;First support 1 is by angle Shape lug-mounted 12, main body 11, rectangular lug-mounted 13 form;For assembly, angular lug-mounted 12 and the rectangular installation of misplacing Auricle 13 is located at the top and bottom of the two sides of each support;The schematic diagram of support such as Fig. 3, if the main body 11 is band A cuboid for dry semicircle card slot, the both side ends in main body 11 in card slot add " arch " connected in star, " arch " connected in star partly Diameter is adapted with the radius of 3 contact surface of binding post, and the depth D of groove is slightly below the thickness h of contact surface;Between two card slots Partition is stretched out perpendicular to the direction of main body, the face where partition is parallel with semicircular circle central axis;The thickness of main body 11 with connect The distance between 3 two contact surfaces of terminal are adapted;After assembling, the height of partition is slightly above the height of the end face of binding post 3 H, as shown in Figure 5.

The angular lug-mounted 12 is the triangular piece of one mounting hole of band;The rectangular lug-mounted 13 is band The rectangular pieces of two mounting holes, in order to which two support dislocation are fixed, and open mounting hole less on firewall as far as possible.

The protective cover 4 divides for upper cover and lower cover, and both ends have installation sheet, the angular peace of the installation sheet and support Dress auricle 12 is adapted, and the depth of protective cover is adapted with the height of 11 partition of main body.

The material of the protective cover 4, the first support 1 and the second support 2 is fiberglass reinforced phenoplasts insulating materials.It connects Terminal 3 selects copper material, and according to connection electric wire and terminal specifications design difference size, and suggests taking different thicknesses wiring Column specification reaches error-preventive design;This terminal plate has the protective cover 4 for preventing foreign matter from falling into, and is simple to manufacture, the structure with aircraft Bracket is connected with screw, it is ensured that will not fall off.It is specifically used to see that Fig. 1, this terminal plate selected materials are common insulating materials And standard component, manufacturing process is simple, and cost is relatively low, and backing plate, pedestal are connected, it can be achieved that quickly tearing open with screw between protective cover Dress has biggish application value.
