Description

A kind of tester high-performance radio-frequency coaxial connector

Technical field

The utility model relates to Precision Inspection field, is specifically related to tester high-performance radio-frequency coaxial connector.

Background technology

Radio frequency (RF) coaxial connector, is widely used in microwave communication, post and telecommunications engineering, and aerospace measurement system, in precision measurement field.The high-performance radio-frequency coaxial connector of using for intermodulation testing instrument, because the intermodulation requirement to connector itself is very high, while requiring 243dBm test, intermodulation requirement-166dBC, so so far, only have the connector that external Ji Jia major company can production this type.

The way of existing solution radio frequency (RF) coaxial connector intermodulation, normally uses without magnetic copper rod and is processed into housing, then electroplates ternary alloy three-partalloy, and insulating barrier adopts polytetrafluoroethylene, and inner wire is made with elasticity bronze, then electroplates silver layer.

Current domestic intermodulation testing instrument high-performance radio-frequency coaxial connector, mainly relying on the customization of external producer provides, and orders goods, production cycle is long, expensive, often from placing an order to, takes product, consuming timely the shortlyest also want half a year, the demand of such supply of material seriously and in China is opposing.And the at present domestic producer that also occurs energy replace imported connector.

Used test connector, relies on import, high cost, and the order cycle time is long, changes to substitute limited by external producer, causes inconvenience to actual test.

Utility model content

The utility model provides a kind of tester high-performance radio-frequency coaxial connector, and the utility model has solved used test connector, relies on import, high cost, order cycle time is long, changes to substitute limited by external producer, causes the problem of inconvenience to actual test.

For addressing the above problem, the utility model adopts following technical scheme: a kind of tester high-performance radio-frequency coaxial connector, comprise the assembly that inner wire 2, insulator 3 and guide pin bushing 5 form, inner wire 2 and a whole insulator 3 adopt tight fit modes, inner wire 2 is pressed into from left to right in insulator hole, at a right-hand member close-fitting unification guide pin bushing 5 of inner wire 2 endoporus, inner wire 2 right sides and guide pin bushing 5 left ends clamp insulator 3;

The assembly integral body of above-mentioned formation is press-fit in the inner chamber of housing 1 from right to left, and insulator 3 is interference fit with housing 1;

Bushing pipe 4 is pressed in the endoporus of housing 1 from right to left, and bushing pipe 4 left sides withstand on insulator 3 edges, right side, and insulator 3 left end edges withstand on the step of housing 1 inner chamber.

Further, a kind of tester of the present utility model also has following features with high-performance radio-frequency coaxial connector: the size range of the distance a of bushing pipe 4 outstanding housing 1 right sides is 0.1～0.25mm, and the width C size range of the circular planes of bushing pipe 4 right sides is 1.5～2mm.

The utility model is a kind of intermodulation testing instrument high-performance radio-frequency coaxial connector.High intermodulation testing connector of the present utility model, all use domestic existing material and equipment, process-cycle is short, and practical effect can reach the performance of imported product, has facilitated domestic tester manufacturer to develop the better instrument of cost performance and has served more enterprise.

Embodiment

With best embodiment, the utility model is described in detail below.

As shown in Figure 1, a kind of tester high-performance radio-frequency coaxial connector, comprise the assembly that inner wire 2, insulator 3 and guide pin bushing 5 form, inner wire 2 and a whole insulator 3 adopt tight fit modes, inner wire 2 is pressed into from left to right in insulator hole, at a right-hand member close-fitting unification guide pin bushing 5 of inner wire 2 endoporus, inner wire 2 right sides and guide pin bushing 5 left ends clamp insulator 3, have prevented the vibration of insulator 3;

The assembly integral body of above-mentioned formation is press-fit in the inner chamber of housing 1 from right to left, and insulator 3 is interference fit with housing 1, prevents that the fine particle things such as dust are adsorbed on the inwall of housing, thereby affects the intermodulation of product.

The bushing pipe 4 of two end surfaces best bright finishes is pressed in the endoporus of housing 1 from right to left, and bushing pipe 4 left sides withstand on insulator 3 edges, right side, and insulator 3 left end edges withstand on the step of housing 1 inner chamber.

The size range of the distance a of bushing pipe 4 outstanding housing 1 right sides is 0.1～0.25mm, and the width C size range of the circular planes of bushing pipe 4 right sides is 1.5～2mm.

The utility model main feature is: between (one) bushing pipe and housing right side specialized designs an intermodulation step ring, high 0.1～0.25mm, circular planes width 1.5～2mm, can guarantee that between housing, contact is good, thereby make the intermodulation value long-term stability of test connector in higher level.(2) insulator adopts overall structure, and between housing and inner wire, all adopts tight fit, prevents that the fine particle thing in use procedure is adsorbed onto connector inside, thereby guarantees that the intermodulation value of product is stabilized on very high numerical value always.

The utility model with the advantage that existing import test connector is compared is: production cost is low, and handling ease is with short production cycle, has met the growth requirement of present domestic tester.

The utility model with the advantage that existing domestic other test connector is compared is: specialized designs intermodulation ring, adopt integral insulation, guaranteed that the intermodulation performance long-term stability of test connector is on high level.

Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection range of the present utility model.
