Description

Radio frequency (RF) coaxial connector signal testing coupling arrangement

Technical field

The utility model relates to a kind of radio frequency (RF) coaxial connector coupling arrangement when being used for communication apparatus and testing.

Background technology

Be extensive use of the radio frequency (RF) coaxial connector of various models in the communication apparatus.Because the good characteristic of radio frequency (RF) coaxial connector, not only the connection of radiofrequency signal, a lot of digital signals also uses.

When the non-radio frequency class veneer that has used radio frequency (RF) coaxial connector is carried out the test of function and performance, need to use certain device to be connected, thereby realize the communication between tested veneer and the external environment condition with radio frequency (RF) coaxial connector.How making this connection reach fast and accurately, is the problem that need solve when testing.

In the prior art, have three kinds of schemes that the radio-frequency (RF) coaxial head is connected:

Scheme 1: use cable to connect, promptly use radio-frequency cable to connect the radio-frequency maser and the test environment of the radio frequency (RF) coaxial connector on the measurand.This scheme is simple and easy to realize, but the plug of cable is entirely by manually carrying out, inefficiency, and the life-span of radio-frequency cable is limited, needs often replacing.

Scheme 2: use common rf probe, promptly the afterbody of rf probe has radio-frequency cable, and the other end of radio-frequency cable has another radio frequency (RF) coaxial connector, is used for connecting external environment condition.In this scheme, measurand need design special test point, radio frequency (RF) coaxial connector and the parallel connection of test point signal.Utilize rf probe engaged test point, realize the communication of signal.The advantage of this scheme is to realize the robotization of test operation, and shortcoming is that the cost of rf probe is higher, and intensity is relatively poor, because of reasons such as installation or misoperations, very easily damages.And must design special test point on measurand, the model coupling of the rf probe that the size of test point must and be selected does not possess versatility.

Scheme 3: use the special-purpose radio-frequency probe, this scheme and scheme 2 are similar, and different is that this class rf probe does not need test point, can be directly and radio frequency connector dock, be solution preferably at present.But such rf probe is with high costs, and need select different rf probes at the radio frequency connector of different model, does not possess versatility, therefore uses not extensive at present.

In sum, in the prior art scheme, scheme 1 inefficiency is unfavorable for large scale test, and scheme 2 is reliable and stable inadequately, and cost is higher, and scheme 3 is with high costs, has increased testing cost.

The utility model content

Problem to be solved in the utility model is that the low and medium frequency signal at non-radio frequency class provides a kind of with low cost, simple in structure, easy to use, reliable and stable radio frequency (RF) coaxial connector signal testing coupling arrangement.

The technical scheme that the utility model adopted is: radio frequency (RF) coaxial connector signal testing coupling arrangement comprises mounting blocks, probe groups a and probe groups b and radio-frequency cable, be processed with two through holes on the described mounting blocks in order to press-fit probe groups a and probe groups b respectively, described radio-frequency cable comprises radio frequency cable and radio frequency (RF) coaxial connector, radio frequency (RF) coaxial connector is welded on an end of radio frequency cable, the core of the described radio frequency cable other end is connected with probe groups a, and the screen layer of the other end is connected with probe groups b.

Described probe groups a comprises probe and needle guard, and probe inserts in the needle guard; Described probe groups b comprises probe and needle guard, and probe inserts in the needle guard, and the other end core that described radio frequency cable does not weld radio frequency (RF) coaxial connector is welded on the needle guard afterbody of probe groups a, and the screen layer of the other end is welded on the needle guard afterbody of probe groups b.

The beneficial effects of the utility model are: the utility model has overcome that the prior art scheme exists or inefficiency or performance shakiness or shortcoming such as with high costs, because the characteristic of probe, but making that connecting robotization carries out, testing efficiency is protected; Because probe is directly visited the pin that connects radio frequency (RF) coaxial connector, reliable and stable, test performance is protected; Because common probe groups price is quite cheap, thereby greatly reduces cost, and makes simple, easy for installation.
