Abstract
The utility model relates to radio transmission apparatus technical field, especially a kind of tunable filter.Link length on existing filter is fixed immutable, is not well positioned to meet different user demands, and traditional thread connecting mode sealing neither be fine.This tunable filter comprises filter main body and is arranged on the PIN joint at filter main body two ends, and PIN joint and filter main body junction are provided with telescopic tube, and telescopic tube is connected to outside filter main body by plug connector mode.Tunable filter structure after improvement is simple, and jiont treatment convenient disassembly is quick, and adjustable in length, be applicable to the connection of various demand, good airproof performance, filtration efficiency is high.
Description
Technical field
The utility model relates to radio transmission apparatus technical field, especially a kind of tunable filter.
Background technology
The filter circuit that power-supply filter is made up of electric capacity, inductance and resistance, a kind of passive bidirectional network, its one end is power supply, the other end is load, it is the device that ripple is filtered, it can carry out effective filtering to the frequency beyond the frequency of characteristic frequency in power line or this frequency, obtains the power supply signal of a characteristic frequency, or eliminates the power supply signal after a characteristic frequency.Link length on existing filter is fixed immutable, is not well positioned to meet different user demands, and traditional thread connecting mode sealing neither be fine.
Utility model content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of tunable filter.
The utility model solves the technical scheme that its technical problem adopts: a kind of tunable filter, comprise filter main body and the PIN joint being arranged on filter main body two ends, PIN joint and filter main body junction are provided with telescopic tube, and telescopic tube is connected to outside filter main body by plug connector mode.
The beneficial effects of the utility model are, structure is simple, and jiont treatment convenient disassembly is quick, and adjustable in length, be applicable to the connection of various demand, good airproof performance, filtration efficiency is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. filter main body in figure, 2.PIN joint, 3. telescopic tube.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of tunable filter, comprise filter main body 1 and the PIN joint 2 being arranged on filter main body 1 two ends, PIN joint 2 and filter main body 1 junction are provided with telescopic tube 3, and telescopic tube 3 is connected to outside filter main body 1 by plug connector mode.During use, the extension elongation of PIN joint 2 can be regulated by telescopic tube 3, adapt to the joint demand of various different length with this.
Tunable filter structure after improvement is simple, and jiont treatment convenient disassembly is quick, and adjustable in length, be applicable to the connection of various demand, good airproof performance, filtration efficiency is high.
