Description
Technical field
The invention belongs to aircraft electrical harness installing area, particularly, it relates to a kind of for supporting sealed through air tight cabin plate of aircraft electrical harness.
Background technique
When aircraft electrical harness passes through airtight bulkhead, conventionally there is following several mode: a kind of is the electric coupler of using gastight type, sealing means is the sealing that relies on electric coupler itself, because needs are by reconnecting by electric coupler after electrical harness disconnection, so poor reliability and expensive; Another kind is that electrical harness passes prefabricated rubber hole, and sealing means is to rely on coordinating of electric wire and rubber hole, every wire all need to be passed separately to a rubber hole, install and use inconvenience.
Summary of the invention
In order to address the above problem, the invention provides a kind of sealed, it can make aircraft electrical harness pass through easily airtight bulkhead.In addition, sealed of the present invention can also make aircraft electrical harness realize bonding, thereby overcomes the deficiencies in the prior art, fully meets the designing requirement of aircraft electrical harness.
Sealed of the present invention comprises columniform body and back-up ring, and described body is provided with the center hole passing for electrical harness, and comprises:
Fixing part, it is positioned at one end of described body, and is provided with at least one glue filling opening, and described glue filling opening communicates with described center hole;
Flange plate, it is positioned on the outer circumferential face of described body, and is provided with at least one glue discharging opening, and described glue discharging opening communicates with described center hole;
Joint, it is positioned at the other end of described body, and is provided with back-up ring groove for placing described back-up ring and the shielding groove for the housing of holding electrical wire harness, and described back-up ring groove is than the more contiguous described flange plate of described shielding groove.
Preferably, described body is formed by two semicircular hollow thin-wall cylindrical body docking, like this can be so that install.One in described 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, made by metallic material for described sealed.
Preferably, described sealed metallic material by plating nickel on surface is made.
For example, described metallic material is aluminum alloy material.
Preferably, described sealed also comprises packing ring, and described packing ring is placed between described flange plate and described back-up ring.
Beneficial effect of the present invention is:
Sealed of the present invention increases a groove structure, and this groove structure is connected for through walls of metal sealing and electrical harness external shroud, thereby reaches the object of bonding.In addition, select such as aluminum alloy material of metallic material, and at the plating nickel on surface of device, make the device of aluminum alloy nickel plated there is splendid electric conductivity.Therefore, through walls of metal sealing of the present invention, does not need to disconnect electrical harness, does not need one by one electric wire to be passed to sealed yet, just can make aircraft electrical harness pass through easily airtight bulkhead, and meet the bonding requirement of aircraft electrical harness.
Brief description of the drawings
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in further detail, wherein:
Fig. 1 is the perspective view of through walls of metal sealing of the present invention;
Fig. 2 is the structural representation of the end face of one and half shells of through walls of metal sealing of the present invention;
Fig. 3 is the perspective view of one and half shells of through walls of metal sealing of the present invention;
Fig. 4 is the scheme of installation of through walls of metal sealing of the present invention.
Embodiment
Fig. 1 shows sealed 100 of the present invention, and it passes through airtight bulkhead and realize bonding function for supporting aircraft electrical harness.Through walls 100 of sealing is made up of metallic material, is preferably made up of the metallic material of plating nickel on surface, and for example this metallic material can be aluminum alloy material.In the present embodiment, the material of employing is aluminum alloy (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 the center hole 15 passing for electrical harness.This body 10 is formed by two semicircular hollow thin-wall cylindrical bodys or half shell 11,12 docking.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 one 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 symmetrically in the present embodiment 4 glue filling openings 21.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 this glue discharging opening 31, in the interior extension of flange plate 30, 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 arrange on other position.Figure 2 illustrates 2 glue discharging openings 31.Joint 40 is positioned at the other end of body 10, and is provided with back-up ring groove 41 for placing back-up ring 50 and the shielding groove 42 for the housing (not shown) of holding electrical wire harness 60, and back-up ring groove 41 is than more adjacent flange dish 30 of shielding grooves 42.
Again in conjunction with shown in Fig. 4, in the time carrying out the installation of aircraft electrical harness, first on the airtight bulkhead 200 of aircraft, open a circular hole, again electrical harness 60 is passed to circular hole, with two and half shells 11,12 in wire harness outside to through walls 100 of a synthetic complete metal sealing, by through walls metal sealing 100 circular hole passing on airtight bulkhead 200, until flange plate 30 is close to airtight bulkhead 200.Flange plate 30 on through walls 100 of metal sealing should be in airtight region.At the opposite side (non-air-tight section) of seal diaphragm 200, back-up ring 50 is stuck in the back-up ring groove 41 of through walls of metal sealing, through walls metal sealing 100 is fixed with back-up ring 50.If necessary, can between airtight bulkhead 200 and back-up ring 50, add packing ring (not shown).The external shroud of electrical harness is fixed in the shielding groove 42 of through walls 100 of metal sealing with stainless steel cassette tape.Then, the two ends of sealed 100 seal with adhesive plaster, in glue filling opening 21, inject sealer, until sealer reserves from glue discharging opening 31.After solidifying Deng sealer, the installation that metal sealing is through walls has accused.
Through walls of metal sealing of the present invention, does not need to disconnect electrical harness, does not need one by one electric wire to be passed to sealed yet, just can make aircraft electrical harness pass through easily airtight bulkhead, has met again the bonding requirement of aircraft electrical harness.
