Abstract
The utility model relates to a kind of extraordinary aviation plug curved sandwich type elements of stainless steel of whole essence casting forming, it includes the curved formula aviation plug shell of thin-walled, and the curved formula aviation plug shell of thin-walled is made up of the equal curved shell straight on rectangular flange and rectangular flange front integrally formed.The utility model compensates for the deficiency of existing aviation plug shell, whole essence casting, and one-pass molding improves safety, the reliability of air plug；The weight that is spirally connected for saving multiple assembling parts has the special equipment important in inhibiting of particular/special requirement to loss of weight；Shielding action will be substantially better than aviation plug made of more assembling parts.
Description
Technical field
The utility model belongs to aviation plug field, and in particular to a kind of special type aviation plug with whole essence casting forming not
Become rusty the curved sandwich type element of steel.
Background technique
Aviation plug is called military project plug, multi-purpose to gain the name aboard.It is the popular call of electric connector, also known as aviation
Connector, aviation electric connector, because initially be used in aviation field due to gain the name, be now widely used in navigation, space flight, aviation, national defence,
The fields such as military affairs, nuclear industry, electric power, enclosure material are sturdy and durable frequently with magnesium alloy, stainless steel etc..
Its main function is to connect power supply or signal, especially for the more harness of core number, uses aviation plug
Socket connects, not only securely and reliably, easy to operate, more aesthetics.
And in classification, and be divided into military aviation and insert and insert two kinds with civil aviation, general lathe, machinery, industry control, in instrument
Connection be all civil aviation insert connection；General aviation can be divided to insert again to insert with waterproof aviation, straight and curved formula aviation plug, plate
Formula and printing board type, buckle-type etc., various classification are provided to facilitate the practical application of product.
Aviation plug is made of shell, insulator, three big unit of contact.
Aviation plug shell refers to the shell, coupling nut, tail accessory of plugs and sockets.The effect of shell is protection insulation
The air plugs internal element such as body and contact is injury-free, and positioning spline guarantees that plug and socket position, and coupling nut is used for plug
Seat is connected and is separated, and tail accessory is for protecting conducting wire and contact injury-free and for fixing cable, and in addition shell also has
There is certain shielding action.
Shell generally uses bar machine to add, plate squeezes or die casting forms, but its limitation is exactly that shape and structure cannot mistake
In complexity, it otherwise must be divided into several parts and process respectively, refill be made into a complete housing unit later, so both increase
Shell substance also adds design and manufacture cost.
Utility model content
The purpose of this utility model is to solve the above problems, and provides a kind of whole essence casting, and one-pass molding improves aviation plug
Safety, reliability；The weight that is spirally connected for saving multiple assembling parts has the special equipment of particular/special requirement to have emphatically loss of weight
Want meaning；Shielding action will be substantially better than the whole essence casting forming of extraordinary aviation plug of space flight plug made of more assembling parts
The curved sandwich type element of stainless steel.
To achieve the above object, the utility model provides the following technical solutions:
A kind of curved sandwich type element of stainless steel of the whole essence casting forming of special type aviation plug comprising the curved formula aviation plug of thin-walled
Shell, the curved formula aviation plug shell of thin-walled by rectangular flange and rectangular flange front on etc. straight curved shell pass through injection molding
It is integrally formed composition.
Further, the curved formula aviation plug shell of the thin-walled needs machine to add fitting surface, mounting hole out.
The utility model compensates for the deficiency of existing aviation plug shell, whole essence casting, and one-pass molding improves air plug
Safety, reliability；The weight that is spirally connected for saving multiple assembling parts has the special equipment that loss of weight has particular/special requirement important
Meaning；Shielding action will be substantially better than air plug made of more assembling parts.
Detailed description of the invention
In order to illustrate more clearly of the utility model embodiment technical solution, will make below to required in embodiment description
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model in order to more clearly
Illustrate the utility model embodiment or technical solution in the prior art, for those of ordinary skill in the art, is not paying
Out under the premise of creative work, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the positive structure diagram of the utility model；
Fig. 2 is the present invention looks up structural representation of the utility model；
Fig. 3 is the cross section A-A schematic diagram of the utility model.
Specific embodiment
The curved sandwich type element of stainless steel of whole essence casting forming is used referring to a kind of special type aviation plug shown in Fig. 1~3, including thin
The curved formula aviation plug shell of wall, the curved formula aviation plug shell of thin-walled is by isometrical on 2 front of rectangular flange 2 and rectangular flange
Straight curved shell 1 is by being integrally formed composition.
The utility model uses investment pattern precision casting technology, and shell inner mold channel is formed by water-soluble core, by 2 He of flange seat
Deng curved 1 block cast of shell forming straight, finally only needing machine to add out, fitting surface, mounting hole can be directly assembled and used with socket.
The specific preparation process of the utility model is as follows:
1. separately designing shape metal die in manufacture aviation plug shell first；
2. first preparing inner mold type core with water-soluble material；
3. the type core prepared is embedded in compacting external form wax-pattern in exterior mold by core print positioning again；
4. solution-off water-soluble core after wax pattern modulus checks wax pattern internal diameter and wall thickness dimension；
5. last routinely investment pattern precision casting technique: Gu group tree → shell → dewaxing → casting → cleaning → cutting → reconditioning processed →
Molten processing → ball blast refine → inspection → delivery.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
