Abstract
The utility model discloses a novel broadband cavity merit divide ware, including connecing cavity, same mandrel rod, joint, insulator, set up in the cavity with the mandrel rod to it is fixed through insulator and cavity, one end with the mandrel rod is provided with the jack, connect and adopt threaded connection with the cavity. The beneficial effects of the utility model reside in that solved the shortcoming of the unable third order intermodulation of improvement qualification rate when considering the outward appearance among the prior art, improved the merit and divided ware intermodulation stability to improved the merit and divided ware protection level, reduced the merit simultaneously under limited ability and divided ware cavity structures the size.
Description
Technical field
This utility model relates to a kind of novel broadband cavity power divider, particularly to a kind of high-performance cavity (N-type/DINd type) power splitter.
Background technology
At present, the chamber power divider that prior art uses, cavity and do not have insulant to fix in cavity between coaxial rod, joint is with being screw fastening on cavity, and power splitter is limiting performance lower chamber physical dimension greatly, and third order intermodulation is not high, intermodulation is unstable, and traditional performance is bad.
Summary of the invention
The purpose of this utility model is that and overcomes disadvantages mentioned above, designs a kind of novel broadband cavity power divider.
In order to realize foregoing invention purpose, this utility model adopts the following technical scheme that
A kind of novel broadband cavity power divider, including connecing cavity, coaxial rod, joint, insulator, described coaxial rod is arranged in cavity, and is fixed by insulator and cavity; One end of described coaxial rod is provided with jack; Described joint adopts with cavity threadeds.
Preferably, described joint is DINd type joint, is provided with lock pin in described DINd type joint, adopts interference fit between described jack and lock pin.
Preferably, described DINd type joint is provided with boss.
Preferably, described DINd type joint is provided with sealing ring.
Preferably, described joint is N connector.
Advantage of the present utility model and effect are in that between coaxial rod and cavity to be fixed by insulator, joint is connected by thread connecting mode with cavity, joint rises boss, and adds sealing ring, adopting interference fit between DINd type connector receptacle and contact pin, N-type power splitter jack is N connector contact pin. Therefore third order intermodulation is good and stable, and traditional performance is superior, and physical dimension is little, and assembling is simple.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one
As depicted in figs. 1 and 2, insulator 6 is installed on coaxial rod 5, afterwards coaxial rod 5 is put in cavity 1, jack 4 is acted to be fastened on coaxial rod 5, by joint 2(with boss 7 with a son) lock pin 3 be docked on jack 4 and then spin joint 2 in cavity 1 and fasten by frock.
Embodiment two
As shown in Figure 3 and Figure 4, insulator 6 is installed on coaxial rod 5, afterwards coaxial rod 5 is put in cavity 1, being risen with a son by jack 4 is fastened on coaxial rod 5, jack 4 is the lock pin of joint 2, reserved boss 7 on joint 2, is docked on jack 4 by joint 2 and then spins joint 2 in cavity 1 and fasten by frock.
A kind of novel broadband cavity power divider of this utility model, is mainly used in the distribution for completing signal power in indoor distributed system and synthesis. Its feature is fixed by insulator between coaxial rod and cavity; Joint is connected by thread connecting mode with cavity; Joint rises boss and adds sealing ring; Adopting interference fit between DINd type connector receptacle and contact pin, N-type power splitter jack is N connector contact pin. Gu third order intermodulation is good and stablizes, traditional performance is superior, and physical dimension is little, and assembling is simple, produces and has higher first-time qualification rate.
