Provided is a low-leakage automatic adjustable diplexer including a body, a thin plate and two resonant regulators. The body has therein cuboid waveguide channels each having a feeding portion, a reception port portion, a transmission port portion, a fitting portion, a first filtering portion, a second filtering portion, first E/H conversion units connected to two ends of the first filtering portion, respectively, and second E/H conversion units connected to two ends of the second filtering portion, respectively. The thin plate is clamped inside the body. The resonant regulators each have a plurality of frequency disturbance elements adjustably protruding into the first and second filtering portions. Given the E/H conversion units and the frequency disturbance elements penetratingly disposed on the H-side sidewall of the cuboid waveguide cavity, it is unnecessary for the cuboid waveguide channels to undergo any processing process for forming therein any protrusion-style insulation walls, thereby attaining low leakage.

A zeroing structure applicable to an adjustable diplexer includes a substrate, holder, motor, lead screw, displacement plate, stop element and interference element. The holder is disposed on the substrate. The motor is disposed on the holder. The lead screw is rotatably disposed on the holder and connected to the motor, and thus rotation of the lead screw is driven by the motor. The displacement plate is movably disposed on the substrate and helically connected to the lead screw so as to undergo linear motion between a first position and a second position relative to the substrate when guided and driven by the motor. The stop element is disposed on the lead screw. The interference element is disposed on the displacement plate and at the position that allows the interference element to come into contact with the stop element when the displacement plate is at the first position. The zeroing structure enables the adjustable diplexer operable at an adjustable center frequency to perform mechanical zeroing and enables primary or auxiliary confirmation of zeroing detection. Furthermore, the zeroing structure is highly reliable and incurs low cost.

A non-contact frequency automatic tuning filter with an antileakage chamber includes a first casing with a first cavity formed at a first opening of the first casing, a moving part, and a second cavity. The second cavity has a second casing, a chamber formed in the second casing, and second and third openings penetrating through the second casing. The moving part is plugged from the third opening into the first cavity or from the third opening into a space between the third opening and the first cavity. The second opening proximate to the moving part constitutes a part of the chamber. The second casing has a spacing portion proximate to the moving part for separating the moving part and chamber. The first and second casings are not in contact with the moving part. The invention can prevent leakage of electromagnetic waves and unstable frequency shifting.

A plug socket is composed by a lower housing, an upper housing, a coiled spring strip and a turning tray. In the lower housing are provided with conductive clips. A circular trough is provided in the top portion of the upper housing. A plurality of plug slots and a hollow with a central hole are provided in the circular trough. The hollow is provided for the coiled spring strip to be placed in, and the inner wall of the hollow is provided with an inserting groove for the outer end of the coiled spring strip to be inserted into. The turning tray is provided to be inlaid in the circular trough. On the bottom of the turning tray is protrudently provided with an axle, which has an inserting groove for the inner end of the coiled spring strip to be inserted into. The axle is provided to penetrate through the passing hole and then to be pivoted in a retaining ring. The turning tray is provided with a plurality of plug slots. In normal times, the turning tray can cover the plug slots of the upper housing to prevent from dust and water and to prevent children from playing with the plug slots and from getting an electric shock.
