Preferably, jack is offered on the plugboard, and plugboard fixation is connected to the inside of fixed inserting groove.

Preferably, the inserting column is fixedly plugged in the inside of fixed jack.

Preferably, the inside of the heat sink is equipped with miniature heat emission fan.

Preferably, the thread jack holds the side wall of seat through entire bottom.

Preferably, it is installed with kinking bar between the electronic component.

Compared with prior art, the beneficial effects of the utility model are：

1st, the utility model bottom holds the upper end of seat and is plugged with end cap, and the inserting column that end cap is symmetrically installed by lower end can It is held in the fixed jack that the upper end of seat opens up with being quickly plugged on bottom, is quickly contained so as to which end cap can be realized by bottom It puts and is mounted and dismounted on seat, and offer jack in the middle part of inserting column on the plugboard of installation, plugboard fixation is connected to fixation Shank is inserted into so as to ensure that end cap can be firmly in the inside of inserting groove using the inside of thread jack to fixed inserting groove Be fixed on bottom and hold the upper end of seat, and remove and install it is convenient and efficient, convenient for bottom is held the electronic component inside seat into Row repair and replacement effectively reduce the scrappage of wave filter.

2nd, the utility model bottom holds and is mounted with kinking bar between the electronic component of installation inside seat, convenient in installation electricity Wiring during subcomponent, facilitates the installation and repair of filter internal element, and the inside of heat sink is mounted with miniature in end cap Heat emission fan can effectively cool down to the electronic component of filter internal, effectively prevent wave filter because temperature is excessively high And break down, substantially prolong the service life of wave filter.
