Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, this utility model is further described, but not as restriction of the present utility model.

In view of existing combiner needs to be assembled by multiple parts, and the quality of fit of parts and parts is required significantly high, and there is the product simultaneously assembled also need repeated multiple times debugging could realize many defects such as response curve of required wave filter, this utility model provides a kind of combiner structure, and the sub-part needed for this structure is few, assembly precision requirement is low, can realize broader frequency band selection.

Concrete, if Fig. 1 is the rearview of this utility model combiner；

Fig. 3 is the structural representation of Novel combiner in this utility model；

This combiner includes:

Combiner base plate 1, combiner top board 2, strip line filter plate 6, some adapters 3 and some fixing screws.

Concrete, combiner top board 2 has buckle structure 5, and combiner base plate 1 has the notch 4 being mutually matched with buckle structure 5, therefore can be realized the fixing integration of combiner top board and combiner base plate by this buckle and draw-in groove.

In embodiment of the present utility model, the structural representation of strip line filter plate 6 is as shown in Figure 2, it is mainly disposed on combiner base plate 1, making strip line filter plate 6 and combiner base plate 1 be formed with lower chamber, specifically described strip line filter plate 6 as shown in Figure 3 is positioned over the region on combiner base plate 1.

Combiner top board 2 is arranged on strip line filter plate 6, and forms an entirety by the buckle structure 5 being mutually matched and notch 4 with combiner base plate 1, and wherein combiner top board and strip line filter plate are formed with upper cavity；

Combiner base plate both sides are also respectively provided with the some adapters 3 being electrically connected with strip line filter plate.
