Though radar and the development of airborne self-defence electronic warfare system and application prospect are very extensive, yet for producing communication equipment producer, can only be by the cutting of cable/connector assembly be satisfied corresponding requirements.Because each cutting and install and all be difficult to accomplish " just right ", thus need carry out repetitious cutting, Installation And Test could roughly reach requirement, and also the phase matched precision also is difficult to improve.As careless slightly, just can scrap in a large number, make production cost increase greatly because of cutting the excessive cable that causes, be unfavorable for the popularization and the use of equipment, for the phase matched one by one of the system of a plurality of unit, it is more outstanding that the problems referred to above just become.And traditional technological requirement debugging staff's quality is than higher, the debugging staff must carry out strict calculating to incision principle and Cutting Length in the Installation and Debugging process, this just makes increase greatly the effective time of whole erection debug process, cutting has repeatedly simultaneously also strengthened the debugging intensity of workers greatly, thereby cause specific productivity low, be unfavorable for producing in enormous quantities.
Three, utility model content:
The utility model provides a kind of sliding locking mechanism of phase place tunable radio frequency coaxial connector in order to solve the weak point in the above-mentioned background technology, and its shock resistance is strong, phase place is adjustable, and the insertion loss is low, and standing-wave ratio is less and have advantages of higher stability, and is easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sliding locking mechanism of phase place tunable radio frequency coaxial connector, its special character is: comprise and be located at the middle Adjusting bolt Adjusting screw of connector, Adjusting bolt Adjusting screw and outer conductor sliding contact are to being connected, inner wire sliding contact pair and outer conductor sliding contact are to being connected, two locking nuts are with Adjusting bolt Adjusting screw and the locking of front and back outer conductor, the outer conductor sliding contact constitutes repeatedly being overlapped by two cylindric parts, interior contact tube front end screw thread and Adjusting bolt Adjusting screw cooperatively interact, the inner wire sliding contact is formed the contact pin that links to each other with cable core by one and the deep hole of an inner wire rear end, and its corresponding insulator embedding of internal plug seat and outer jack is fixed.
Contact tube placket is four grooves or six grooves in above-mentioned, the outstanding circle in the contact site of front end.
It is 4 that above-mentioned internal plug seat afterbody is split the groove number, and the jack of internal plug seat afterbody closes up, and the jack degree of depth of internal plug seat afterbody is much larger than the displacement of interior contact tube and outer contacting tube.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
The utility model sliding locking mechanism employing Adjusting bolt Adjusting screw drives the mutual slip between internal plug seat and outer jack, interior contact tube and the outer contacting tube, cooperates the correspondingly requirement of equipment thereby change the whole electrical length of assembly.Thereby, easy to adjust, the degree of regulation height, it is low to insert loss, and standing-wave ratio is less and have advantages of higher stability and shock resistance is good, and application is wide.Cost has been saved in the waste of having avoided cutting repeatedly and having caused, and helps a large amount of productions and the popularization of equipment, has vast market prospect.
