Background technology

Existingly be widely used between the digital multiplex equipment, the radio frequency (RF) coaxial connector between digital multiplex equipment and programme-controlled exchange or the non-voice service equipment, comprise conductive shell and outer conductor that is threaded with this conductive shell and outer contacting part, in the endoporus of described conductive shell, be provided with along its first, second axial arranged insulator, be provided with heart yearn in this first, second insulator; Be provided with in described outer conductor with its endoporus tight fit and along its 3rd axial arranged insulator and the 4th insulator, be provided with first inner wire in described the 3rd, the 4th insulator, this first inner wire adopts the jack type inner wire with jack; Described outer contacting part has two and along the radial arrangement of described conductive shell, in two outer contacting parts, be provided with its endoporus tight fit and along the 5th insulator and the 6th insulator of its axially-aligned, be provided with second inner wire in described the 5th, the 6th insulator, this second inner wire adopts the contact pin type inner wire with contact pin; Described first inner wire and second inner wire place an end of described conductive shell endoporus to be electrically connected with described heart yearn by welding respectively; Also be respectively equipped with the 7th insulator and the 8th insulator at the endoporus two ends of described conductive shell, this two insulator respectively with the metal backup shoe close-fitting at two ends.

The radio frequency (RF) coaxial connector of this structure, on the one hand, because the face of cylinder of heart yearn and the axial end of first, second inner wire are directly welded in the connector, this syndeton is poor reliability not only, get loose easily, and usually occur rosin joint aborning, leak the phenomenon of weldering, cause the electrical property of connector relatively poor even lost efficacy; On the other hand, because the insulator that uses in the connector reaches ten, thereby the employed insulator of the connector of this structure is more, so not only increased recruitment and Master Cost greatly, improved production cost, and made the complex structure of connector, load and unload very inconveniently, production efficiency is lower.

The utility model content

The technical problems to be solved in the utility model provides a kind of heart yearn and is connected with inner wire reliably, and is simple in structure, easy to loading and unloading and radio frequency (RF) coaxial connector that production cost is low.

For solving the problems of the technologies described above, the utility model adopts so a kind of radio frequency (RF) coaxial connector, comprise conductive shell and the outer conductor and the outer contacting part that removably connect with this conductive shell, be provided with heart yearn in the endoporus of described conductive shell, be respectively equipped with first inner wire and second inner wire in the endoporus of described outer conductor and outer contacting part, described first inner wire and second inner wire place an end of described conductive shell endoporus to be electrically connected with described heart yearn by welding, be provided with in described outer conductor and friction tight first insulator of its endoporus, described first inner wire places in described first insulator; Be provided with in described outer contacting part and friction tight second insulator of its endoporus, described second inner wire places in described second insulator; Described first inner wire and second inner wire place an end of described conductive shell endoporus to offer the groove that is used for the described heart yearn of setting-in respectively, and described first inner wire and second inner wire are electrically connected with described heart yearn by constituting in the welding of chimeric place.

In the utility model, the described groove that is used for the setting-in heart yearn is preferably the yi word pattern direct through groove, this yi word pattern direct through groove and described heart yearn tight fit.

First inner wire of the present utility model is the jack type inner wire with jack, and second inner wire is the contact pin type inner wire with contact pin.

After adopting such structure, on the one hand, because an end of first inner wire and second inner wire is offered the groove that is used for the setting-in heart yearn, therefore when mounted, heart yearn can be embedded behind the groove, can guarantee that like this heart yearn and inner wire can link together reliably in the welding of chimeric place, can not get loose, thereby guaranteed that connector has good electrical properties, simultaneously, leakage weldering, problem of faulty soldering that this setting-in Welding Structure has often occurred in also having avoided producing; On the other hand, owing in outer conductor and outer contacting part, only use an insulator, therefore, connector of the present utility model only uses three insulators, uses at least ten insulators to compare with prior art, the utility model has reduced the use amount of insulator part in the electric loop greatly, so not only reduced recruitment and Master Cost, reduced production cost, but also made the structure of connector become more simple, loading and unloading and keep in repair more conveniently and have improved production efficiency greatly.
