It is more advantageous.And the connection cylinder shell 1 of the design is designed to the revolving body sleeve shaped of the entity of no splicing seams, can be fully solved
Housing by insulator expansive force when by spreading the problem of.
Metal deep drawn is a kind of special process in metal stamping, and punching press is carried out using sheet metal, and draw ratio is big, thick
Uniform sheet metal is spent in drawing process due to deformation, thickness can be slightly changed, the wall thickness of the outer conductor 2 of deep drawn formation
Finally slightly has difference.But this difference is distinct to rush using the method for welding, welding or the leaching other metals of high-temperature fusion
The product splicing seams of writing that surpasses all the others circle are stitched together, the wall thickness difference formed at splicing seams；Or using tradition such as turning or millings
Machine tooling technique processing housing due to wall thickness difference caused by step, neck etc., especially in crimping, bulge loop and projection etc.
The wall thickness difference formed at structure.The wall thickness of the outer conductor 2 formed by deep drawn is generally uniform, and its wall thickness difference is much smaller than upper
The wall thickness difference of the housing of processing mode processing is stated, be can be ignored substantially.
Using metal casting or the plastic injection processing uniform outer conductor 2 of wall thickness, due to the design of mould pattern draft, material
Expect that wall thickness difference is also smaller caused by reason for cooling meat etc., can be ignored substantially, but if using metal casting or
The even outer conductor 2 of plastic injection processing wall unevenness, when molten metal or plastics are cooled down in mould, part is not
It is even with position inhomogeneous cooling, shrink uneven, part can produce the quality problems such as warpage, distortion, and the place of wall thickness can produce contracting
Water, scarce material, interior tissue are loose, and manufacturability is poor.Therefore, when the uniform wall thickness of outer conductor 2, be also suitable for using metal casting or
Person's plastic injection processing technology.
The method for being connected the product splicing seams of punching press edge rolling with the metal for welding or soaking high-temperature fusion processes outer
Conductor, because welding material or the metal of high-temperature fusion are inconsistent typically with product base material, can form difference at splicing seams
Material, thickness is also uneven, and the outer conductor 2 of the design uses metal deep stretching process, and block of metal sheet stamping is drawn
The revolving body outer conductor structure of stretching tubular, or casting or the revolving body outer conductor structure for being molded growth tubular, lead outside
Circumferencial direction of body 2 itself is without splicing seams, and in whole circumference direction, material is consistent, and thickness is uniform, without again connecting splicing seams
Get up.Here material unanimously does not include using after plastic injection again in the material of the increased metallic conduction coating in surface.

Shooting Technique is produced.The product that the deep stretching process production present invention is designed, is compared to metal casting or plastic injection technique,
Production efficiency is higher, and product quality is more preferable.Metal casting or plastic injection technique can heat the material to high temperature, make material
State is changed, and the good condition of heat treatment of metal material is changed, and is easy to oxidation, plastic material under the condition of high temperature
As heating is easy to aging, performance reduction, material can be reduced with temperature and shunk, influence product size essence after the cooling period
Degree, the evacuation of interiors of products tissue, hydraulic performance decline.
Either metal deep drawn, metal casting or plastic injection, are required for investing mould, disposable input is big, only
Have when being in great demand, the expense that one-time investment is shared on every product is very low, the direct production of every product
The totle drilling cost of cost and one-time investment share the expenses sum just can be very low.Outer conductor 2 in the design is standard component, and difference is long
The adapter of degree can share this standard component, and their demand can accumulate to realize the total production cost of small outer conductor 2,
It is turning part or milling part to connect cylinder shell 1, it is not necessary to which big one-time investment, cost also will not be too high when quantity is small.
When the adapter quantity required of a certain length is little, still it can be realized by Split type casing assembly structure relatively low
Production cost.Certainly, connection cylinder shell 1 can also use metal punching volume, metal deep drawn, casting of metals, the work such as plastic injection
Skill is produced.
In summary, RF coaxial adapters of the present invention, outer conductor uniform wall thickness, no splicing seams, in addition to face coat
For same material, outer conductor uses metal deep stretching process, or using metal casting, plastic injection (surface re-plating gold
Category conductive layer) etc. technique productions be made；The design of the capsid, overcomes the tradition such as existing use turning or milling
Machine tooling long tubular outer conductor consumable material it is many, the outer conductor for the tubular being rolled into punching press or bending has splicing seams,
Intensity and toughness is poor, product quality when the even outer conductor of material wall unevenness uses the technique productions of metal casting or plastic injection
It is not high, the problem of manufacturability is bad；Simultaneously when adapter capsid entire length is very long, it is possible to reduce expensive material
