Abstract
The utility model pertains to a radio frequency coaxial connector in a mobile communication system, and specifically relates to a welding type radio frequency connector. The welding type radio frequency connector comprises an inner conductor, an insulator, and an outer conductor. The outer conductor has a hollow structure. The insulator is embedded into the middle portion of the outer conductor and matched with the outer conductor closely. The inner conductor is in insulating connection with the outer conductor through the insulator. The outer conductor is provided with a welding section. In the process of installation, the welding section of the outer conductor and the outer conductor layer of a cable are welded and connected together, and the tail end of the inner conductor and the inner conductor of the cable are welded and connected together. According to the utility model, advantages of simple structure, easy welding and easy installation can be realized, the welding speed and the welding quality can be doubled, and at the same time, the tin dosage is greatly reduced, the third-order intermodulation performance of the radio frequency connector can be improved, and the stability and consistency of the product quality can be improved.
Description
Technical field
The utility model belongs to the radio frequency (RF) coaxial connector in mobile communcations system, is specifically related to a kind of solder type radio frequency connector.
Background technology
In mobile communcations system, the application of radio-frequency (RF) coaxial feeder line is very extensive.The function of feeder line be the more important thing is high-quality transmission radio-frequency (RF) energy and signal except playing mechanical connection.Because radio frequency (RF) coaxial connector is a kind of non-linear element, so in the process of transmission radio-frequency (RF) signal, can make the signal distorted, produce the passive intermodulation phenomenon, intermodulation product appears.These intermodulation products can disturb the first-harmonic signal, cause communication system the higher error rate to occur, have a strong impact on communication quality.Therefore, for the connector that mobile communication is used, the high request of third order intermodulation is arranged.
All must effectively weld in order to improve the performance of third order intermodulation of radio frequency connector, important measures are wherein arranged the internal and external conductor that is requirement connector and cable.The welding of outer conductor is the most key, particularly to the 1/2S ultra-soft feed line of the indoor consumption maximum of machine room, on the existing market, structure ubiquity scolding tin is difficult to trickling evenly, easily produce rosin joint or bubble cavity and cause three rank degradations or unstable, and soldering-wire dosage is very large, causes cost to be difficult to descend.
Summary of the invention
For addressing the above problem, the utility model provide a kind of simple in structure, performance of third order intermodulation is excellent and lower-cost feeder line solder type radio frequency connector, effectively with cable outer conductor and connector welding, reach the purpose that improves performance of third order intermodulation, and reduced the tin amount of using.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of solder type radio frequency connector comprises inner wire, insulator, outer conductor, and described outer conductor is hollow structure, and described insulator is embedded in middle part and the tight fit with it of outer conductor, and described inner wire insulate with outer conductor by insulator and is connected; Described outer conductor is provided with welding section, and during installation, the welding section of described outer conductor and the outer conductor layer of cable are weldingly connected, and the tail end of described inner wire and the inner wire of cable are weldingly connected.
Be as further improvement of the utility model: the inwall of described outer conductor welding section is processed into the thread-like structure that is complementary with cable.Such helical structure had both improved the axial stability of cable, had guided again the scolding tin flow direction simultaneously, and can discharge smoothly by gap between screw the high-temperature gas that soldering produces, and itself and cable outer conductor are well merged.In addition, the shape of threads inwall consistent with feeder line and the feeder line of welding position can effectively be fitted, and have reduced the filling gap of former tin amount, use the tin amount to reduce by 50%.
The utility model makes welding operation simpler, and has significantly improved the quality of speed of welding and welding.The unequal problem of scolding tin trickling when having solved welding, thereby the stability of improving the quality of products and consistency.

Fig. 1 is assembly structure cutaway view of the present utility model;
In figure: insulator 1; Center hub 11; Outer conductor 2; Welding section 21; Inner wire 3; Cable 4; Outer conductor layer 41;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
embodiment, as shown in Figure 1, the utility model relates to a kind of solder type radio frequency connector, comprise insulator 1, outer conductor 2, inner wire 3, described outer conductor 2 inside are hollow structure, described insulator 1 be embedded in outer conductor 2 the middle part and with its inwall tight fit connection, described insulator is provided with center hub 11, described outer conductor 2 is provided with welding section 21, the inwall of described welding section 21 is processed into the thread-like structure that is complementary with cable, during installation, described inner wire 3 axially inserts center hub 11 and is connected with outer conductor 2 insulation by insulator 1
When installing cables 4, cable 4 front ends are stripped the outer conductor layer 41 of exposing cable, inner wire 3 tail ends of connector and the inner wire of cable are weldingly connected, then axially screw in connector be in Fig. 1 A to, the outer conductor layer 41 of cable 4 and welding section 21 inwalls of outer conductor are closely cooperated, the center hub 11 that inner wire 3 inserts on insulators; After attaching puts in place, the end of conductor welding section 21 is by the induction heating equipment HFI welding outside, and constantly add tin, make the scolding tin thawing of being heated between cable outer conductor 41 and outer conductor 2, reach connector and the cable 4 uniform effects of welding, and the high-temperature gas that produces during welding is discharged smoothly by gap between screw.
The utility model is simple in structure, welded and installed is convenient, and significantly improved the quality of speed of welding and welding, and greatly reduce simultaneously and use the tin amount, improved the performance of third order intermodulation of radio frequency connector, improve stability and the consistency of product quality, had market prospects preferably.
