Description
Technical field
The invention belongs to aircraft electrical harness installing area, particularly, it relates to and a kind ofly is used to support the aircraft electrical harness and passes sealed of air tight cabin plate.
Background technique
When the aircraft electrical harness passes through airtight bulkhead; Following several kinds of modes are arranged usually: a kind of is electric coupler with gastight type; Sealing means is the sealing that relies on electric coupler itself, connects again by electric coupler because of needs break off the back with electrical harness, so poor reliability and costing an arm and a leg; Another kind is that electrical harness passes prefabricated rubber hole, and sealing means is to rely on cooperating of electric wire and rubber hole, need every wire all be passed a rubber hole separately, installs and uses inconvenience.
Summary of the invention
In order to address the above problem, the present invention provides a kind of sealed, and it can make the aircraft electrical harness pass through airtight bulkhead easily.In addition, sealed of the present invention can also make the aircraft electrical harness realize bonding, thereby overcomes the deficiency of existing technology, fully satisfies the designing requirement of aircraft electrical harness.
Sealed of the present invention comprises columniform body and back-up ring, and said body is provided with and is used for the center hole that electrical harness passes, and comprises:
Fixing part, it is positioned at an end of said body, and is provided with at least one glue filling opening, and said glue filling opening communicates with said center hole;
Flange plate, it is positioned on the outer circumferential face of said body, and is provided with at least one glue discharging opening, and said glue discharging opening communicates with said center hole;
Joint, it is positioned at the other end of said body, and is provided with the back-up ring groove and the shielding groove that is used for fixing the housing of electrical harness that is used to place said back-up ring, and said back-up ring groove is than the more contiguous said flange plate of said shielding groove.
Preferably, said body is formed by two semicircular hollow thin-wall cylindrical body butt joints, like this can be so that install.One in said two semicircular hollow thin-wall cylindrical bodys is provided with protruding positioning key on end face, and another is provided with recessed positioning key on corresponding position.
Preferably, process by metallic material for said sealed.
Preferably, said sealed the metallic material by plating nickel on surface processed.
For example, said metallic material is an aluminum alloy material.
Preferably, said sealed also comprises packing ring, and said packing ring is placed between said flange plate and the said back-up ring.
Beneficial effect of the present invention is:
Sealed of the present invention increases a groove structure, and this groove structure is used for being connected of through walls of metallic seal and electrical harness external shroud, thereby reaches the purpose of bonding.In addition, select for example aluminum alloy material of metallic material for use, and, make the device of aluminum alloy nickel plating have splendid electric conductivity at the plating nickel on surface of device.Therefore; Through walls of metallic seal of the present invention need not broken off electrical harness, does not need a root ground that electric wire is passed sealed yet; Just can make the aircraft electrical harness pass through airtight bulkhead easily, and satisfy the bonding requirement of aircraft electrical harness.
Description of drawings
Below in conjunction with accompanying drawing preferred implementation of the present invention is described in further detail, wherein:
Fig. 1 is the perspective view of through walls of metallic seal of the present invention;
Fig. 2 is the structural representation of end face of one and half shells of through walls of metallic seal of the present invention;
Fig. 3 is the perspective view of one and half shells of through walls of metallic seal of the present invention;
Fig. 4 is the scheme of installation of through walls of metallic seal of the present invention.
Embodiment
Fig. 1 shows sealed 100 of the present invention, and it is used to support the aircraft electrical harness and passes through airtight bulkhead and realize the bonding function.Through walls 100 of sealing processed by metallic material, preferably processed by the metallic material of plating nickel on surface, and for example this metallic material can be an aluminum alloy material.In the present embodiment, the material of employing is aluminum alloy (a GB/T3191-1998 aluminium and aluminium alloy extruded rods), and surface treatment is nickel plating.
Shown in Fig. 1-3, this through walls 100 comprises columniform body 10, and body 10 is provided with and is used for the center hole 15 that electrical harness passes.This body 10 is formed by two semicircular hollow thin-wall cylindrical bodys or 11,12 butt joints of half shell.One and half shells 11 are provided with protruding positioning key or projection 13 on end face, and another half shell 12 is provided with recessed positioning key or groove 14 on corresponding position, and two and half shells can be docking together thus.Certainly, can also adopt other Placement, for example be threaded etc.Body 10 comprises fixing part 20, flange plate 30 and joint 40.Fixing part 20 is positioned at an end of body 10, and is provided with at least one glue filling opening 21, and this glue filling opening 21 communicates with center hole 15, is provided with 4 glue filling openings 21 in the present embodiment symmetrically.Flange plate 30 is positioned on the outer circumferential face of body 10, and it is an annular protrusion, and this flange plate 30 is provided with at least one glue discharging opening 31, and extend in flange plate 30 this glue discharging opening 31, communicates with center hole 15, and the opening of glue discharging opening 31 is positioned at joint 40 1 sides.Certainly, glue discharging opening 31 can also be provided with on other position.2 glue discharging openings 31 have been shown in Fig. 2.Joint 40 is positioned at the other end of body 10, and is provided with the back-up ring groove 41 and the shielding groove 42 that is used for fixing the housing (not shown) of electrical harness 60 that is used to place back-up ring 50, and back-up ring groove 41 is than shielding more adjacent flange dish 30 of groove 42.
Combine shown in Figure 4 again; When carrying out the installation of aircraft electrical harness; At first on the airtight bulkhead 200 of aircraft, open a circular hole, again electrical harness 60 passed circular hole, with two and half shells 11,12 in wire harness outside to through walls 100 of a synthetic complete metallic seal; With through walls 100 circular hole that passes on the airtight bulkhead 200 of metallic seal, be close to airtight bulkhead 200 up to flange plate 30.Flange plate 30 in through walls 100 of the metallic seal should be in airtight zone.Opposite side (non-air-tight section) at seal diaphragm 200 is stuck in back-up ring 50 in the back-up ring groove 41 of through walls of metallic seal, with back-up ring 50 through walls 100 of metallic seal is fixed.If necessary, can between airtight bulkhead 200 and back-up ring 50, add the packing ring (not shown).The external shroud of electrical harness is fixed in the shielding groove 42 of through walls 100 of metallic seal with the stainless steel cassette tape.Then, seal with adhesive plaster at sealed 100 two ends, in glue filling opening 21, injects sealer, till sealer is reserved from glue discharging opening 31.After solidifying Deng sealer, completion is promptly accused in the installation that metallic seal is through walls.
Through walls of metallic seal of the present invention need not broken off electrical harness, does not need a root ground that electric wire is passed sealed yet, just can make the aircraft electrical harness pass through airtight bulkhead easily, has satisfied the bonding requirement of aircraft electrical harness again.
