Abstract
Description
Technical Field
[0001] The utility model relates to a fine tuner, in particular to a high-precision phase fine tuner. Background Art
[0002] The phase fine-tuning signal generator is a measuring instrument used in the field of mathematics. Due to the wide application of microwaves in communications, military and civilian fields, the demand for microwave modules has increased dramatically. The wavelength of microwaves is short, only at the micron or millimeter level. The design of microwave modules often has index requirements for phase or phase consistency. In actual production and assembly, a very small assembly error will introduce a large phase difference, affecting the realization of the index. The power amplifier module is a difficult point in the design of microwave modules. The power synthesis is also closely related to the phase of each channel, so the phase adjustment of the microwave channel is particularly important.
[0003] At the same time, after the phase fine tuner has been working for a certain period of time, although a heat dissipation unit is provided on its inner side, the heat dissipation capacity is relatively constant. After working continuously for a certain period of time, the heat dissipation is relatively slow, which can easily affect the operating accuracy of the phase fine tuner. Utility Model Content

[0008] The movable plate is also connected to the electromagnetic support assembly installed in the phase fine-tuner body.

[0013] It also includes an induced draft fan, which is arranged on the inner side of the induced draft cavity.

DETAILED DESCRIPTION
[0024] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.
[0025] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
[0026] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific examples below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.
[0027] See also Figures 1 to 5 In an embodiment of the utility model, a high-precision phase fine-tuner includes a phase fine-tuner body 1, a through slot 2 is formed on the phase fine-tuner body 1, and also includes a movable plate 3, the movable plate 3 is movably installed in the phase fine-tuner body 1, and the frame-type slide 6 formed on the movable plate 3 passes through the through slot 2, a plurality of heat dissipation fins 7 are installed at a position located inside the frame-type slide 6 on the movable plate 3, an air induction component is provided at a position located inside the frame-type slide 6 on the movable plate 3, the movable plate 3 is also connected to an electromagnetic support component installed in the phase fine-tuner body 1, when the electromagnetic support component is energized, the movable plate 3 moves toward the outside of the phase fine-tuner body 1, so that the side end of the phase fine-tuner body 1 is in a conductive state, and the air induction component works synchronously.
[0028] When the phase fine-tuner body 1 is working, the side end of the phase fine-tuner body 1 is in a blocked state, and the heat generated on the inner side of the phase fine-tuner body 1 is naturally dissipated through the channel formed in the induced draft component to ensure the normal operation of the phase fine-tuner body 1. When the heat dissipation efficiency of the phase fine-tuner body 1 is low, the electromagnetic support component is energized. At this time, the side end of the phase fine-tuner body 1 is turned on, and the induced draft component starts to work, so that the outside air enters the interior of the phase fine-tuner body 1 through the side end of the phase fine-tuner body 1, and then flows out through the induced draft component, thereby achieving rapid heat dissipation. In this embodiment, the side end of the phase fine-tuner body 1 is blocked or turned on to achieve the blocking of the side end of the phase fine-tuner body 1 when the channel dissipates heat, thereby eliminating the possibility of dust entering the side end of the phase fine-tuner body 1, thereby ensuring the cleanliness of the inside of the phase fine-tuner body 1 to a certain extent.
[0029] Combined with the activity state of the above-mentioned movable plate 3, it can be known that when the movable plate 3 is energized in the electromagnetic support assembly, it will move upward to a certain extent, which can increase the inner space of the phase fine-tuner body 1 and play an explosion-proof role, thereby increasing the working stability of the phase fine-tuner body 1 and increasing the working accuracy of the phase fine-tuner body 1 to a certain extent, and has strong practicality.
[0030] It should also be noted that the frame-shaped slide 6 is slidably fitted with the inner wall of the through slot 2 to ensure the directional movement of the movable plate 3 .
[0031] Specifically, see Figure 2 and Figure 3 At least two second through holes 11 are formed on both sides of the phase fine adjuster body 1, and side plates 4 perpendicular to the movable plate 3 are fixed at both ends of the movable plate 3. At least two first through holes 5 are formed on the side plates 4. When the first through holes 5 are staggered with the second through holes 11, the side end of the phase fine adjuster body 1 is blocked. When the electromagnetic support assembly is not energized, the bottom of the movable plate 3 and the electromagnetic support assembly are in abutment state. At this time, the first through holes 5 on the side plates 4 and the second through holes 11 on the phase fine adjuster body 1 are in a completely staggered state. At this time, the side end of the phase fine adjuster body 1 is in a blocked state, and no gas flow occurs inside and outside the phase fine adjuster body 1. When the movable plate 3 moves up a certain distance, the first through holes 5 and the second through holes 11 are staggered within a certain range. At this time, the side end of the phase fine adjuster body 1 is connected, so that the gas flow inside and outside the phase fine adjuster body 1 is realized to expand the heat dissipation area.
[0032] Preferably, dustproof nets are installed on the inner sides of the first through hole 5 and the second through hole 11. The setting of the dustproof nets can eliminate external dust from entering the inner side of the phase fine-tuner body 1 to a certain extent, thereby achieving the purpose of dust prevention. By way of example, in a specific implementation manner, the first through hole 5 and the second through hole 11 are both bar holes or square holes, which can be selected according to actual needs, and this embodiment does not make any specific limitation on this.
[0033] For further information, see Figure 2 and Figure 3 The induced draft component includes an induced draft cavity 8 formed on the movable plate 3, and the induced draft cavity 8 is connected with the inner side of the phase fine tuner body 1 through a heat dissipation channel 13 formed on the movable plate 3; and also includes an induced draft fan 9, and the induced draft fan 9 is arranged on the inner side of the induced draft cavity 8. When the induced draft fan 9 is working, negative pressure is generated, so that the higher temperature gas on the inner side of the phase fine tuner body 1 is guided to the outside, so as to achieve the purpose of heat dissipation. When the induced draft fan 9 is not working, the heat dissipation channel 13 is always in a conducting state, so as to keep the inside and outside of the phase fine tuner body 1 in a connected state, so that when the phase fine tuner body 1 is heated up, the higher temperature gas can overflow along the heat dissipation channel 13 to achieve heat dissipation.
[0034] Preferably, an annular groove is formed on the side of the air induced cavity 8 away from the movable plate 3, and a dustproof plate 10 arranged in an annular structure is placed in the annular groove. The dustproof plate 10 can be made of magnetic material, so that when the dustproof plate 10 is placed in the annular groove, it will not fall off at will. Of course, in the specific implementation process, a card groove can also be provided on the inner wall of the annular groove, and an elastic card block is provided on the dustproof plate 10. When the dustproof plate 10 is installed in the annular groove, the elastic card block can be inserted into the card groove to fix the dustproof plate 10.
[0035] Furthermore, the electromagnetic support assembly includes a plurality of electromagnetic receiving members 12 mounted on the inner wall of the phase fine-tuner body 1, and a magnet 14 is provided on the side of the movable plate 3 facing the electromagnetic receiving member 12. When the electromagnetic receiving member 12 is energized, the opposite magnetic poles of the electromagnetic receiving member 12 and the magnet 14 are the same. When the electromagnetic receiving member 12 is not energized, the movable plate 3 maintains an abutment state with the electromagnetic receiving member 12 under the action of gravity and the attraction between the magnet 14 and the electromagnetic receiving member 12. When the electromagnetic receiving member 12 is energized, a repulsive force is generated between the electromagnetic receiving member 12 and the magnet 14, thereby causing the movable plate 3 to move upward to achieve a displacement action.

Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
