According to the characteristic impedance computing formula of RF coaxial adapters
wherein Z
c: coaxial transmission line characteristic impedance, ε
r: the relative dielectric coefficient of the insulator between coaxial adatpter internal and external conductor, d: adapter inner conductor outer diameter, D: adapter outer conductor or housing inner diameter.The internal diameter D of the interface portion of outer conductor 2 is preferably 3.01 ~ 6.95mm, the adapter that this scope makes this adapter less relative to other can bear larger electrical installation power, volume is also more moderate, and operating power and volume can reach a good compromise.The length of outer conductor 2 is preferably 3 ~ 10mm, the length of fit of outer conductor in interface portion of general adapter can be met, adapter can be made again can be designed to length the shortest, after making the socket connector interworking at adapter and two ends, distance between a pair circuit board (or the module of installing) welded with the connector at two ends is the shortest, reach and make that final complete machine finished product or module are miniaturized, the object of low cost, this length range is also meeting compromise best between interface fit length and final complete machine miniaturization; When needing the spacing between large circuit board or between module, only need the length lengthening connecting cylinder housing 1.
Outer conductor 2 adopts metal deep stretching process to be made, and raw material are the product uniform wall thickness of the uniform sheet metal of thickness, metal deep drawn, and when producing, waste material is few, and save material, production efficiency is high, and cost is low, and production capacity is large.Especially, when adapter length is very long, the housing that the outer conductor 2 of this design is assembled into, has more advantage in cost, performance quality, production capacity and production efficiency.And the connecting cylinder housing 1 of the design is designed to the revolving body sleeve shaped of the entity without splicing seams, can solve completely when housing is subject to the expansive force of insulator by the problem of spreading.
Metal deep drawn is a kind of special process in metal stamping, use sheet metal to carry out punching press, draw ratio is large, the uniform sheet metal of thickness in drawing process due to distortion, thickness can slightly change, the final slightly difference of wall thickness of the outer conductor 2 that deep drawn is formed.But this difference being different from uses welding, the product splicing seams of punching press volume circle is stitched together by the method for welding or leaching high-temperature fusion other metal, the wall thickness difference formed at splicing seams place; Or adopt the wall thickness difference that the housing of traditional machine tooling processes such as turning or milling causes due to step, draw-in groove etc., especially in the wall thickness difference that the structure places such as crimping, bulge loop and projection are formed.The wall thickness of the outer conductor 2 formed by deep drawn is roughly even, and the wall thickness difference of the housing that its wall thickness difference is processed much smaller than above-mentioned processing mode is substantially negligible.
Adopt the outer conductor 2 of metal casting or plastics injection molding uniform wall thickness, the wall thickness difference caused due to reasons such as the design of mould pattern draft, material cooled contractions is also less, substantially negligible, if but adopt metal casting or the even outer conductor 2 of plastics injection molding wall unevenness, when molten metal or plastics cool in mould time, part different parts inhomogeneous cooling is even, shrink uneven, part can produce the quality problems such as warpage, distortion, the place of wall thickness can produce shrink, lack material, interior tissue is loosened, and manufacturability is poor.Therefore, when the uniform wall thickness of outer conductor 2, be also suitable for adopting metal casting or plastics injection molding technique.
With the metal of welding or leaching high-temperature fusion, the method that the product splicing seams of punching press volume circle couples together is processed outer conductor, metal due to welding material or high-temperature fusion is general and product base material is inconsistent, different materials can be formed at splicing seams place, thickness is also uneven, and the outer conductor 2 of the design uses metal deep stretching process, by the revolving body outer conductor structure of block of metal sheet stamping stretching growth tubular, or the revolving body outer conductor structure of casting or injection moulding growth tubular, the circumferencial direction of outer conductor 2 own is without splicing seams, consistent at whole circumferencial direction material, thickness is even, without the need to again splicing seams being coupled together.The material of the metallic conduction coating that material here increases on surface after unanimously not comprising the injection moulding of employing plastics again.
The outer conductor 2 preferable alloy deep stretching process of the design is produced, and metal casting or plastics Shooting Technique also can be selected in addition to produce.The product of deep stretching process production the present invention design, be compared to metal casting or plastics Shooting Technique, production efficiency is higher, and product quality is better.Metal casting or plastics Shooting Technique can by heating materials to high temperature, the state of material is made to there occurs change, the condition of heat treatment that metal material is good is changed, and be easy to oxidation under the condition of high temperature, plastic material also can be easy to aging because of heating, performance reduces, material can reduce with temperature and shrink after the cooling period, affect product size precision, interiors of products tissue is evacuated, hydraulic performance decline.
No matter be metal deep drawn, metal casting or plastics injection moulding, all need to invest mould, disposablely to have high input, only have in time being in great demand, the expense that one-time investment is shared on every part product is very low, and the direct production cost of every part product and the total cost of one-time investment share the expenses sum just can be very low.Outer conductor 2 in the design is standard components, the adapter of different length can share this standard component, their demand can accumulate the total production cost realizing little outer conductor 2, connecting cylinder housing 1 is turning part or milling part, do not need large one-time investment, time quantity is little, cost also can not be too high.When the adapter quantity required of a certain length is little time, still can realize lower production cost by Split type casing assembly structure.Certainly, connecting cylinder housing 1 also can rush volume, metal deep drawn, casting of metals, the explained hereafter such as plastics injection moulding with metal.
In sum, RF coaxial adapters of the present invention, outer conductor uniform wall thickness, there is no splicing seams, it is same material except face coat, outer conductor adopts metal deep stretching process, or adopts the explained hereafter such as metal casting, plastics injection moulding (surperficial re-plating metal conducting layer) to be made; The design of this capsid, the outer conductor consumable material overcoming the long tubular of traditional machine tooling such as existing turning or milling is many, the outer conductor of the tubular be rolled into punching press or bending has splicing seams, intensity and toughness is poor, the problem that when the even outer conductor of material walls thickness ununiformity adopts the explained hereafter of metal casting or plastics injection moulding, product quality is not high, manufacturability is bad; Simultaneously when adapter capsid entire length is very long, the use of expensive material can be reduced, reduce further manufacturing cost.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
