Abstract
The invention relates to a testing tool of a radio frequency (RF) coaxial connector, which is characterized in that a tool center conductor, an insulating medium and an outer conductor are sequentially and coaxially arranged in a sleeve type from inside to outside; wherein, the tool center conductor is a column and provided with inserting holes at the two ends, and a connector center conductor canbe inserted into the inserting holes; the insulating medium has jacket structure, and the tool center conductor is supported inside an axial through hole of the insulating medium; the outer conductor is a cylinder, and the two ends of the outer conductor are fixed ends of the coaxial connector. The testing tool has the advantages of simple structure, reliable connection and convenient use; the te sting tool can be used for testing the RF coaxial connector, and the testing results are basically the same as results simulated by software, so that the high accuracy of the testing results can be proved.
Description
Technical field
The present invention relates to be used for the device that microwave communication device detects, a kind of testing tool of radio frequency (RF) coaxial connector of more specifically saying so.
Background technology
At present, generally adopt the method for twin connectors slotted line at the electric performance test of radio frequency (RF) coaxial connector.As shown in Figure 3, specifically be that center conductor 6 with coaxial connector 5 is welded in the groove at conducting rod 7 two ends, coaxial connector 5 is fixed on the frock cavity 8, conducting rod 7 is suspended in the cavity 8, forming one section transmission line detects, this mode has two big drawbacks: the one, and welding manner brings very big systematic error because of the difference of individual technical merit, the 2nd, the position relation of conducting rod 7 in cavity 8 is unfixing, can cause not matching of transfer impedance, and have the transition problem of coaxial cable, and then have a strong impact on measuring accuracy to suspended substrate stripline.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of simple for structure, connect reliable, exempt to weld, easy to use, have superior and stable electric property, testing tool of radio frequency (RF) coaxial connector and a using method thereof that the testing result accuracy is high, can realize the connected mode of not welding to realize one section coaxial transmission line stably again.
The present invention adopts following technical scheme for the technical solution problem:
The design feature of testing tool of radio frequency (RF) coaxial connector of the present invention is:
Be telescopic coaxial successively tool center conductor, insulating medium and the outer conductor of being provided with from inside to outside;
Described tool center conductor is a column, and two ends have can be for the jointing holes of connector center conductor insertion;
Described insulating medium is jacket structured, and tool center conductor is bearing in the axially extending bore of insulating medium;
Described outer conductor is a cylindrical body, and the two ends of outer conductor are the stiff end of coaxial connector.
Design feature of the present invention also is:
Two ends at described insulating medium are provided with compensated loop.
The two ends jointing holes of described center conductor is a throat structure.
Described outer conductor divides two sections settings in the axial direction, and the composition surface between two sections is concavo-convex mating surface.
The present invention uses the theoretical and twin connectors method of testing of coaxial transmission line, and two coaxial connectors are inserted in the tool center conductor back-to-back, forms one section coaxial transmission line, inserts checkout equipment and detects.Between the connector center conductor of coaxial connector of the present invention and the tool center conductor is to be connected by resilient contact, does not need welding, reusable.Compared with the prior art, beneficial effect of the present invention is embodied in: tool structure of the present invention is succinct, connection is reliable, easy to use; Through actual verification, use frock RF coaxial connector of the present invention to detect, the result of its testing result and software simulation is basic identical, has proved the high accuracy of its testing result.
Description of drawings
Fig. 1 is an assembly structure synoptic diagram of the present invention.
Fig. 2 is the assembly structure synoptic diagram in the present invention's use.
Fig. 3 is the assembly structure synoptic diagram that detects in the prior art in the frock use.
Number in the figure: 1 outer conductor, 2 insulating mediums, 2a compensated loop, 3 tool center conductor, 3a jointing holes, 4 axially extending bores, 5 coaxial connectors, 6 connector center conductor.
Below pass through embodiment, and the invention will be further described in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, Fig. 2, present embodiment is telescopic coaxial successively tool center conductor 3, insulating medium 2 and the outer conductor 1 of being provided with from inside to outside;
Fig. 1, shown in Figure 2, tool center conductor 3 is a column, two ends have can be for the jointing holes 3a of connector center conductor 6 insertions; Insulating medium 2 is jacket structured, and tool center conductor 3 is bearing in the axially extending bore 4 of insulating medium 2; Outer conductor 1 is a cylindrical body, and the two ends of outer conductor 1 are the stiff end of coaxial connector 5.
In concrete the enforcement, the corresponding structure form also comprises:
Be provided with compensated loop 2a at the two ends of insulating medium 2,,, improve transmission line, reach the purpose of compensating impedance in the electric capacity of this transition position, the uncontinuity of inductance by the mode of end face processing annular groove with 2 one-tenth integral body of insulating medium.
The two ends jointing holes 3a of tool center conductor 3 is a throat structure, thereby guarantees that tool center conductor 3 contacts well with the center conductor 6 of tested connector.
In the use, the connector center conductor 6 of the coaxial connector 5 of two same sizes inserted from the jointing holes 3a at tool center conductor 3 two ends respectively connect, be separately fixed on the both ends of the surface of outer conductor 1 with the coaxial connector 5 of securing member again two ends, form one section coaxial transmission line, insert checkout equipment and can detect.
