Abstract
The invention discloses a high-performance radio frequency coaxial connector for a test instrument, and relates to the technical field of accurate tests, in particular to the high-performance radio frequency coaxial connector for the test instrument. The connector comprises a component formed by an inner conductor, an insulator and a guide bushing, wherein the inner conductor and the overall insulator adopt a tight fit manner; the inner conductor is pressed into an insulator hole from left to right; the guide bushing is in tight fit with the right end of an inner hole of the inner conductor; the right end surface of the inner conductor and the left end of the guide bushing clamp the insulator; the formed component is in press fit with the interior of an inner cavity of a casing from right to left; the insulator and the casing are in interference fit; a liner tube is pressed into an inner hole of the casing from right to left; the left end surface of the liner tube is butted to the edge of the right end surface of the insulator; and the left end edge of the insulator is butted to a step of the inner cavity of the casing. The high-performance radio frequency coaxial connector provided by the invention solves the problems that the conventional test connector depends on import and is overhigh in cost and overlong in order cycle time, the replacement is limited by foreign manufacturers, and the actual test are extremely inconvenient.
Description
Technical field
The present invention relates to the precision measurement technical field, be specifically related to tester high-performance radio-frequency coaxial connector.
Background technology
Radio frequency (RF) coaxial connector is widely used in microwave communication, the post and telecommunications engineering, and the aerospace measurement system is in the precision measurement field.The high-performance radio-frequency coaxial connector of using for the intermodulation testing instrument, because the intermodulation requirement to connector itself is very high, when requiring the 2@43dBm test, intermodulation requirement-166dBC, so so far, have only the connector that major company of external a few family can production this type.
The way of existing solution radio frequency (RF) coaxial connector intermodulation normally is processed into housing with no magnetic copper rod, electroplates ternary alloy three-partalloy then, and insulating barrier adopts polytetrafluoroethylene, and inner wire is made with the elasticity bronze, electroplates silver layer then.
Domestic intermodulation testing instrument high-performance radio-frequency coaxial connector mainly relies on the customization of external producer order is provided at present, production cycle is long, costs an arm and a leg, and often takes product from placing an order to, consuming timely the shortlyest also want half a year, such supply of material seriously and the demand in China opposing.And the at present domestic producer that inlet outlet connector also do not occur substituting.
Used test connector relies on import, and cost is too high, and the order cycle time is long, changes to substitute limited by external producer, causes inconvenience for actual test.
Summary of the invention
The invention provides a kind of tester high-performance radio-frequency coaxial connector, the invention solves used test connector, rely on import, cost is too high, and the order cycle time is long, changes to substitute limited by external producer, causes the problem of inconvenience for actual test.
For addressing the above problem, the present invention 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, the insulator 3 of an inner wire 2 and an integral body adopts the tight fit mode, inner wire 2 is pressed into from left to right in the 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 an 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 edge, insulator 3 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 invention also has following characteristics with the high-performance radio-frequency coaxial connector: the size range apart from 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 present invention is a kind of intermodulation testing instrument high-performance radio-frequency coaxial connector.High intermodulation testing connector of the present invention, all use domestic existing material and equipment, the process-cycle is short, and practical effect can reach the performance of imported product, make things convenient for domestic tester manufacturer to develop the better instrument of cost performance, served more enterprise.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Symbol description among the figure: housing 1, inner wire 2, insulator 3, bushing pipe 4, guide pin bushing 5.
Embodiment
With illustrated embodiments the present invention 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, the insulator 3 of an inner wire 2 and an integral body adopts the tight fit mode, inner wire 2 is pressed into from left to right in the 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 that the string of insulator 3 is moving;
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 an interference fit with housing 1, prevents that fine particle thing such as dust is adsorbed on the inwall of housing, thereby influences the intermodulation of product.
The bushing pipe 4 of one two end surfaces best bright finish is pressed in the endoporus of housing 1 from right to left, and bushing pipe 4 left sides withstand on edge, insulator 3 right side, and insulator 3 left end edges withstand on the step of housing 1 inner chamber.
The size range apart from 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.
Main feature of the present invention is: between (one) bushing pipe 4 and housing 1 right side specialized designs intermodulation step ring, high 0.1～0.25mm, circular planes width 1.5～2mm can guarantee between the housing that contact is good, thereby the intermodulation value long-term stability that makes test connector is in higher level.(2) insulator adopts overall structure, and all adopts tight fit between housing and inner wire, prevents that the fine particle thing in the use is adsorbed onto connector inside, thereby the intermodulation value that guarantees product is stabilized on the very high numerical value always.
The present invention with the advantage that existing import test connector is compared is: production cost is low, and handling ease is with short production cycle, has satisfied the growth requirement of present domestic tester.
The present invention with the advantage that existing domestic other test connector is compared is: specialized designs the intermodulation ring, adopt integral insulation, the intermodulation performance long-term stability that has guaranteed test connector is on high level.
It should be noted that at last: obviously, the foregoing description only is for example of the present invention clearly is described, and is not the qualification 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 need not also can't give exhaustive to all execution modes.And conspicuous variation of being amplified out thus or change still are among protection scope of the present invention.
