Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical scheme progress to the utility model embodiment is clear, complete Description.

As shown in Figure 1, Figure 2 and Figure 3, the utility model combiner includes half steel cable 1, connector 2 and cavity 3, described Screwed connecting hole 31 is formed with cavity, the half steel cable 1 is threadedly secured in the cavity by the connector 2 Connecting hole 31 in, the use of semi-rigid cable so that the utility model combiner has working frequency high, advantages of good shielding performance, Reliability is high, decays low, standing wave is small, it is easy for installation the features such as.

Specifically, show and be formed with a kind of pectinate line combiner, including cavity 3 and cover plate 4, cavity wall in figure A plurality of pectinate line resonant columns 32 are provided with three threaded connection holes 31, the cavity 3, a plurality of pectinate line resonant columns 32 will Cavity is divided into a plurality of resonators.

With reference to shown in Fig. 4, the half steel cable 1 is coaxial cable, and its ecto-entad includes outer conductor 11, insulation and is situated between successively Matter 12 and inner wire 13, it is preferred that the outer conductor 11 elects tin plating copper material as, the inner wire 13 elects silver-plated copper material as, certainly Optionally, the inner wire and outer conductor can also be other copper materials or other metal materials.

Further say, the inner wire 13 stretches out, the outer conductor 11 is from the end one of dielectric 12 Hold distance and terminate so that dielectric and inner wire difference are exposed.

As shown in figure 5, the connector 2 includes screwing flange 21, fixed part 22 and screw thread portion 23, the fixed part 22 and screw thread portion 23 be formed at the both sides for screwing flange 21, the outer surface of screw thread portion 23 is formed with outer spiral shell Line, described screw is formed with otch 211 on flange 21（As shown in Figure 1）, fixation is easily installed, the fixed part 22 is used for and institute The outer conductor 11 for stating half steel cable 1 is welded and fixed, optionally or crimping etc. other manner fix, it is described to screw Further say that the inner surface of the connector 2 forms an annular platform towards the end of the half steel cable in threaded portion 23 Rank portion 24, one end of outer conductor 11 of the half steel cable 1 terminates at the stage portion 24.

During installation, first half steel cable can be inserted into connector so that outer conductor is resisted against stage portion, then passes through The fixed part of connector is weldingly fixed on the outer conductor of half steel cable, forms half steel cable-assembly, then by mounted cable Component is fixedly mounted on the cavity of combiner by threaded connecting hole, would extend out next half steel cable after fixing again Inner wire is welded and fixed with corresponding pectinate line resonant column, realizes radio signal transmission.

The utility model is welded and fixed by the outer conductor of ring flange and half steel cable, is tightened with flange valve snail line Mode achieves a fixed connection, and is verified through practical operation, program install convenient is fixed, in passive devices such as wave filters Use in debug convenient, test intermodulation is stable, and advantages of good shielding performance decays low, property indices are superior to traditional design Scheme, and the utility model thoroughly solves that the decay brought due to cable-assembly is big, and third order intermodulation is unstable, mechanical performance Unstable, connected mode is cumbersome, the shortcomings of cost is high.
