Description

Sliding sheet supporting device

Technical Field

The present disclosure relates generally to phase shifters. More particularly, the present disclosure relates to a slide supporting device for a phase shifter.

Background

A phase shifter is a device capable of adjusting the phase of a wave. The method has wide application in the fields of radar, missile attitude control, accelerators, communication, instruments and even music and the like. The phase shifter organically combines the transformer phase shifting technology and the digital measurement technology, has high phase shifting regulation precision, accurate and direct reading, adjustable output voltage and current, good output waveform, reliable operation and convenient operation, can meet the test and calibration of high-precision single-phase and three-phase alternating current power, phase and other instruments, and can also be used in a calibration device of a watt-hour meter.

Generally, a phase shifter includes a slide plate that is pressed against a PCB (printed circuit board) and is movable relative to the PCB to change a phase. It is known that in a conventional phase shifter, one end of a slide plate is fixed with respect to a PCB to serve as a rotation center, and the other end is rotatable around the rotation center, thereby enabling the slide plate to rotate with respect to the PCB.

The cost of a PCB is proportional to the area of the PCB, i.e. the larger the area of the PCB, the higher the cost is generally. Thus, a smaller phase shifter has a cost advantage over a larger phase shifter. However, for the phase shifter, the adoption of the above-described rotation type operation principle generally results in a large size of the phase shifter, resulting in an increase in cost.

Disclosure of Invention

It is an object of the present disclosure to provide a slide support device that overcomes at least one of the deficiencies of the prior art.

It is another object of the present disclosure to provide a phase shifter including the above-described slide supporting device.

According to an aspect of the present disclosure, there is provided a slide supporting device for a phase shifter, the phase shifter including a substrate, the slide supporting device may include a cover disposed opposite to the substrate. The slip support may further include a slip support between the cover and the base plate, the slip support may have a first surface facing the cover and a second surface facing the base plate, and a slip may be fixed on the second surface. The slide support device may further comprise a resilient element extending from the first surface of the slide support towards the cover and abutting the cover. The slip sheet support may further comprise a fastening mechanism connecting the cover to the base plate. The resilient element may be compressed between the cover and the slip support.

In one embodiment of the slip support device, the resilient element may extend towards the cover obliquely to the first surface of the slip support and may be movable relative to the cover over a surface of the cover.

In one embodiment of the slider support device, the resilient element may be a resilient finger extending from the first surface of the slider support towards the cover, one end of the resilient finger being fixed to the first surface of the slider support and the other end of the resilient finger being a free end abutting the cover and being movable relative to the cover over the surface of the cover.

In one embodiment of the slide support device, the slide support may be provided with a cut-out in which the resilient element is located when viewed in a direction perpendicular to the first surface, such that the resilient element is capable of deforming towards and into the cut-out when compressed. This configuration has the advantage of saving the space required for the deformation of the elastic element, making the slide support device more compact.

In one embodiment of the slip support device, the free end may have a flat contact surface which is held in contact with a surface of the cover facing the slip support to form a face contact between the resilient element and the cover.

In one embodiment of the slider support device, the free end may have a projection which is held in contact with a surface of the cover facing the slider support to form a point contact between the resilient element and the cover.

In one embodiment of the slide support device, the slide support may be provided with a guide pin, and the cover is provided with a guide slot through which the guide pin passes and is movable within the guide slot.

In one embodiment of the slider support device, a PCB may be fixed on the base plate, the slider abutting against the PCB, wherein the second surface of the slider support completely covers the slider. In case the second surface of the slider support completely covers the slider, the pressing force to the slider support due to the compression of the elastic element can act uniformly on the entire slider, so that the pressing force between the slider and the PCB is uniform.

In one embodiment of the slide support device, the cover, the slide support and the substrate may be arranged parallel to each other and remain arranged parallel during operation of the phase shifter. In this case, the distance between the cover and the substrate is always kept uniform, so that the pressure between the slider and the PCB is uniform.

In one embodiment of the slide support, the slide support may comprise a plurality of resilient elements arranged in a regular manner on the slide support. These elastic elements may have the same configuration and/or they are arranged symmetrically about the guide pin center. In this case, it can help to keep the pressure between the slider and the PCB uniform.

In one embodiment of the slide support device, a locating member may be provided on the slide support and a locating slot may be provided on the cover, the locating member being extendable into the locating slot when the slide support device is assembled.

Referring now to the drawings, FIG. 1 shows an example of a phase shifter 1. As shown in the figure, the phase shifter 1 includes a substrate 10, a first-stage phase shifter 20, a second-stage phase shifter 30, and a transmission mechanism 40. In the following description, a direction along the width of the phase shifter is referred to as a lateral direction, a direction along the length of the phase shifter is referred to as a longitudinal direction, and a direction along the height of the phase shifter is referred to as a vertical direction.

The substrate 10 is a substantially plate-shaped member, and the PCB 50 is fixed to the substrate 10. The first-stage phase shifters 20 and the second-stage phase shifters 30 are disposed above the PCB 50. The first-order phase shifters 20 and the second-order phase shifters 30 may be arranged in a conventional manner, for example, as shown in fig. 1, the first-order phase shifters 20 and the second-order phase shifters 30 are arranged side by side.

The first-stage phase shifter 20 and the second-stage phase shifter 30 each include a slide 60 (see fig. 2), and the slide 60 is configured to abut against the PCB 50 and is movable relative to the PCB 50 to thereby perform phase change.

The transmission mechanism 40 is operatively coupled to the first-stage phase shifter 20 and the second-stage phase shifter 30 to drive the first-stage phase shifter 20 and the second-stage phase shifter 30 to operate. The first-stage phase shifter 20 and the second-stage phase shifter 30 each have a slide supporting device on which the slides 60 are supported, respectively. The transmission mechanism 40 drives the slide support means and thereby the slide 60 in motion relative to the PCB 50.

In one embodiment, the transmission mechanism 40 includes a tie bar 41 and a tie bar support 42, the tie bar support 42 being fixed on the base plate 10, the tie bar 41 being slidably coupled to the tie bar support 42. As shown in fig. 1 and 2, the tie rod 41 is arranged in the longitudinal direction and is movable in the longitudinal direction.

The transmission mechanism 40 further comprises a tie rod connection 43, the tie rod connection 43 being fixedly connected to the tie rod 41, as shown in fig. 1, the tie rod connection 43 being substantially transverse to the tie rod 41, movement of the tie rod 41 causing movement of the tie rod connection 43. The tie bar connection 43 is operatively coupled with the primary phase shifter 20 and the secondary phase shifter 30, and more particularly with the slide support device, whereby movement of the transmission mechanism 40 causes movement of the slide support device, which in turn causes movement of the slide 60 relative to the PCB 50.

The first-order phase shifter 20 and the second-order phase shifter 30 may be of the same or different configurations, and in the illustrated embodiment, the first-order phase shifter 20 and the second-order phase shifter 30 are of different configurations, but this is not limitative, but merely illustrative. As shown in fig. 1 and 2, the two-stage phase shifter 30 is of a slide type construction, including a slide support device 70 according to the present disclosure. The slide support device 70 supports the slide 60 and is operatively coupled to the drive mechanism 40 to cause the slide 60 to slide relative to the PCB 50. The slider supporting device 70 according to the present disclosure will be described in detail below.

Referring now to fig. 3 and 4, fig. 3 shows one example of a slide support device 70. As shown, the slider support device 70 serves to support the slider 60 in the phase shifter such that the slider 60 can slide with respect to the PCB, thereby changing the phase. The slider support device 70 comprises a cover 100, a slider support 200, a resilient element 300 and a fastening mechanism 400.

As shown in fig. 3, the cover 100 is a substantially plate-like member and is provided to face the substrate 10. The cover 100 is connected to the base plate 10 by a fastening mechanism 400 such that the cover 100 is positioned parallel to the base plate 10 but spaced apart from each other, thereby forming a distance between the cover 100 and the base plate 10.

In one embodiment, the fastening mechanism 400 may include a fastener 401. As shown in fig. 4, the fastening mechanism 400 includes four fasteners 401, and the four fasteners 401 are located at four corners of the cover 100, respectively. Through holes 101 for fasteners 401 are provided at four corners of the cover 100, and the fasteners 401 correspondingly pass through the through holes 101.

Through holes are also provided at corresponding positions on the base plate 10, through which the fasteners 401 correspondingly pass. In this way, the fastener 401 connects the cover 100 to the substrate 10 through the through-hole 101 of the cover 100 and the through-hole of the substrate 10.

The slider support 200 is located between the cover 100 and the substrate 10. In one embodiment, the slide support 200 is also a substantially plate-like member having a first surface 201 facing the cover 100 and a second surface 202 facing the substrate 10. The slider 60 is secured to the second surface 202 of the slider support 200. It will be appreciated by those skilled in the art that the slider 60 may be secured to the second surface 202 by any suitable means, for example, the slider 60 may be adhered directly to the second surface 202.

As mentioned above, the transmission mechanism 40 is operatively coupled with the slide support device 70, whereby movement of the transmission mechanism 40 causes movement of the slide support device 70, which in turn causes movement of the slide 60 relative to the PCB 50.

To this end, a coupling mechanism is provided on the slide support device 70, in particular, according to one embodiment, in the form of a guide pin 210. As shown in fig. 3-6, the guide pin 210 is disposed substantially centrally on the slide support 200. In one embodiment, the guide pin 210 is fixed to the slide support 200, and in another embodiment, the guide pin 210 is integrally formed with the slide support 200.

As shown in fig. 5 and 6, a guide pin 210 is provided on the first surface 201 of the slide support 200, extending from the first surface 201 toward the cover 100. The cover 100 is provided with a guide groove 102, and the guide pin 210 protrudes from the guide groove 102 through the guide groove 102. The guide slot 102 may take various types of shapes and sizes. The guide slot 102 extends in a longitudinal direction and has a shape and dimensions matching the range of movement of the guide pin 210 such that the guide pin 210 is able to move within the guide slot 102. Further, the guide pin 102 may be configured to define a range of motion of the guide pin 210. For example, both ends of the guide pin 102 may act as stops to limit further movement of the guide pin 210.

The portion of the guide pin 210 protruding from the guide slot 102 is operatively coupled with the transmission mechanism 40, in particular, with the tie rod connector 43. Thereby, the movement of the tie rod 41 of the transmission mechanism 40 in the longitudinal direction causes the movement of the tie rod link 43 in the longitudinal direction, which brings the guide pin 210 in the guide slot 102 in the longitudinal direction, thereby moving the slide support 200 in the longitudinal direction, which in turn moves the slide 60 fixed on the second surface 202 of the slide support 200 in the longitudinal direction with respect to the PCB 50 abutting against the PCB 50.

The resilient element 300 is located between the cover 100 and the slide support 200, extends from the first surface 201 of the slide support 200 towards the cover 100, and finally abuts the cover 100.

As shown in fig. 3, the elastic element 300 extends towards the cover 100 obliquely with respect to the first surface 201 of the slide support 200, the tip of the elastic element 300 abuts against the cover 100 and is movable on the surface of the cover 100 facing the slide support 200.

In one embodiment, the resilient element 300 may be in the form of, for example, a resilient finger, extending from the first surface 201 of the slide support 200 towards the cover 100. One end of the resilient finger is a fixed end 301, the fixed end 301 being fixed to the first surface 201 of the slide support 200, or the fixed end 301 being integrally formed with the slide support 200. The other end of the resilient finger is a free end 302, which free end 302 abuts the cover 100 and is movable relative to the cover 100 on the surface of the cover 100 facing the slide support 200.

Fig. 5 shows one embodiment of the slider support 200 and the elastic element 300, and fig. 6 shows another embodiment of the slider support 200 and the elastic element 300. In the embodiment shown in fig. 5 and 6, the fixed end 301 of the elastic element 300 is integrally formed with the slide support 200. A slit 230 is formed on the slide support 200, and a fixed end 301 of the elastic element 300 is at one end of the slit 230. The resilient member 300 is located within the cutout 230, as viewed in a direction perpendicular to the first surface 201, such that the resilient member 300 may be deformed towards the cutout 230 and into the cutout 230 when compressed. Such a configuration has an advantage in that a space required to accommodate the elastic member 300 for elastic deformation can be further saved, so that the slide supporting device 70 can be more compact.

In addition, fig. 5 and 6 respectively show different extension ways of the elastic member 300. In fig. 5, the resilient element 300 extends from the first surface 201 of the slide support 200 towards the cover 100 and away from the guide pin 210, whereas in fig. 6, the resilient element 300 extends from the first surface 201 of the slide support 200 towards the cover 100 and towards the guide pin 210. It will be appreciated by those skilled in the art that any other suitable extension of the resilient element 300 may be used.

The free end 302 of the resilient element 300 may have various forms, such as the form shown in fig. 5 and 6. In one embodiment, this free end 302 has a flat contact surface that is always in contact with the surface of the cover 100 facing the slide support 200. With a flat contact surface, the elastic element 300 makes surface contact with the cover 100. In another embodiment, the free end 302 has a protrusion 303 (see fig. 3), which protrusion 303 is always kept in contact with the surface of the cover piece 100 facing the slide support 200. With the protrusion 303, a point contact is formed between the elastic member 300 and the cover 100. It will be appreciated by those skilled in the art that the free end 302 of the resilient element 300 may also take any other suitable form.

As mentioned above, the elastic element 300 is arranged between the cover 100 and the slide support 200, extending from the slide support 200 to abut against the cover 100. According to an embodiment of the present disclosure, the elastic element 300 is configured to be compressed between the cover 100 and the vane support 200, and to remain compressed throughout the operation of the phase shifter 1.

As the elastic element 300 is compressed between the cover 100 and the slider support 200, the elastic element 300 applies a pressing force to the slider support 200 to push the slider support 200 toward the substrate 10. As described above, the slider 60 is fixed on the second surface 202 of the slider support 200, the PCB 50 is fixed on the base plate 10, and the slider 60 abuts against the PCB 50, and thus, the pressure applied to the slider support 200 by the elastic member 300 causes a pressure between the slider 60 and the PCB 50.

Since the elastic element 300 extends between the cover 100 and the slider support 200, the distance between the cover 100 and the slider support 200 determines the degree to which the elastic element 300 is compressed. In this case, since the slider 60 is fixed on the second surface 202 of the slider support 200, the PCB 50 is fixed on the base plate 10, and the slider 60 abuts against the PCB 50, the distance between the cover 100 and the slider support 200 actually determines the distance between the cover 100 and the base plate 10. That is, when the cover 100 is fixed to the substrate 10 by the fastening mechanism 400, the distance between the cover 100 and the substrate 10 is correlated with the degree to which the elastic member 300 is compressed.

During operation of the phase shifter 1, the slide 60 is required to be pressed against the PCB 50 with a suitable pressure in order to maintain good contact between the slide 60 and the PCB 50 during movement of the slide 60 relative to the PCB 50. At the same time, the pressure between the sledge 60 and the PCB 50 cannot be too high, which might otherwise cause too much friction between the sledge 60 and the PCB 50, resulting in a difficult movement of the sledge 60 with respect to the PCB 50.

Therefore, it is desirable that the pressure between the slider 60 and the PCB 50 be adjustable to provide the appropriate pressure according to actual needs. As is apparent from the above description, the degree to which the elastic member 300 is compressed is associated with the pressure between the slider 60 and the PCB 50, and the distance between the cover 100 and the substrate 10 is associated with the degree to which the elastic member 300 is compressed, and thus, the pressure between the slider 60 and the PCB 50 can be adjusted by adjusting the distance between the cover 100 and the substrate 10.

According to one embodiment of the present disclosure, the distance between the cover 100 and the base plate 10 may be adjusted by selecting different sizes of fastening mechanisms 400. That is, the distance between the cover 100 and the base plate 10 is determined based on the required pressure between the slider 60 and the PCB 50, and an appropriate fastening mechanism 400 is selected according to the distance between the cover 100 and the base plate 10.

According to another embodiment of the present disclosure, the fastening mechanism 400 may be provided with an adjusting device 410, the adjusting device 410 being configured to adjust the distance between the cover 100 and the substrate 10. The adjustment device 410 may take any suitable configuration, for example, an adjustment screw, an indexing adjustment device, etc. may be used.

During operation of the phase shifter 1, it is desirable that the pressure between the slider 60 and the PCB 50 is uniform, thereby improving the operation accuracy of the phase shifter 1.

As described above, the slider 60 is fixed on the second surface 202 of the slider support 200, the PCB 50 is fixed on the base plate 10, and the slider 60 abuts against the PCB 50. According to one embodiment of the present disclosure, the second surface 202 of the vane support 200 is configured to have a larger surface area than the surface area of the vane 60 such that the second surface 202 is able to completely cover the vane 60 when the vane 60 is secured to the second surface 202. In this case, the pressing force to the slider support 200 due to the compression of the elastic member 300 can be uniformly applied to the entire slider 60, so that the pressing force between the slider 60 and the PCB 50 is uniform.

According to one embodiment of the present disclosure, the cover 100, the slide support 200, and the substrate 10 are arranged in parallel with each other and are always maintained in parallel during the operation process of the phase shifter 1.

The cover member 100 and the substrate 10 are made of rigid materials, and the distance between the cover member 100 and the substrate 10 is always kept uniform through the connection of the fastening mechanism 400, so that the cover member 100 and the substrate 10 are kept in parallel.

As described above, the guide pin 210 is substantially centrally disposed on the slide support 200. In order to keep the pressing force of the elastic member 300 generated on the entire slide support 200 uniform, a plurality of elastic members 300 may be provided, and the elastic members 300 may be identically configured elastic members. As shown in fig. 5 and 6, a plurality of elastic elements 300 are arranged on the slide support 200 in a regular manner, preferably symmetrically with respect to the guide pin 210. For example, as shown in fig. 5, according to one embodiment of the slide supporting device 70, two elastic members 300 are provided, and these elastic members 300 are disposed at both sides of the guide pin 210 and are disposed centrally symmetrically with respect to the guide pin 210. For example, as shown in fig. 6, according to one embodiment of the slide supporting device 70, four elastic members 300 are provided, and the elastic members 300 are arranged centrally symmetrically around the guide pin 210. It will be understood by those skilled in the art that the number and arrangement of the elastic elements 300 are not limited thereto, and various other suitable numbers and arrangements are possible according to the needs of the actual application.

With the cover 100, the slide support 200 and the base plate 10 kept parallel to each other, by means of the symmetrical arrangement of the plurality of elastic elements 300, the pressing force on the slide support 200 generated by the compression of the elastic elements 300 can be uniformly applied to the entire slide 60 during the operation process of the phase shifter, which in turn makes the pressing force between the slide 60 and the PCB 50 uniform.

The phase shifter 1 may have a plurality of first-order phase shifters 20 and/or second-order phase shifters 30, in which case it may be necessary to ensure that the pressure between all slides 60 and the PCB 50 is uniform. To this end, the cover 100 may be configured for a plurality of slide supports 70, preferably for all slide supports 70. For example, as shown in fig. 1 and 2, one cover 100 is provided, i.e., one cover 100 is shared by a plurality of slide supports 70, which ensures that the distance between the cover 100 and the base plate 10 is uniform and the same in all the slide supports 70, keeping the cover 100 arranged parallel to the base plate 10.

In this case, the elastic member 300 in each of the slide supports 70 may adopt the same configuration, thereby enabling the pressing force on the slide support 200 generated by the compression of the elastic member 300 to be uniformly applied to the entire slide 60 during the operation process of the phase shifter, and in turn, enabling the pressing force between all the slides 60 and the PCB 50 to be uniform.

It will be appreciated by those skilled in the art that the resilient element may take other forms. For example, when in the form of a resilient finger as described above, the resilient element may be disposed at different angles of inclination relative to the slide support 200, which may affect the pressure experienced by the slide. The resilient fingers may be tapered in width or depth along their length to produce a desired force upon deflection. The position and/or angular arrangement of the resilient fingers may be different from the illustrated example. Furthermore, the resilient fingers may take a curved or serpentine form, have multiple bends and multiple angles (like a spring), and provide pressure due to their compression rather than bending. The resilient element may also include multiple layers to affect the pressure (e.g., may have a damping material as a contact surface to aid in the uniformity of the pressure). Other variations may also be employed.

In one embodiment of the slider support device 70 according to the present disclosure, a positioning member 220 may be provided on the slider support 200, and accordingly, a positioning groove 103 may be provided on the cover 100. As shown in fig. 2 and 4, the positioning member 220 may be disposed on an edge of the slide support 200, protruding from the first surface 201 of the slide support 200 towards the cover 100. When the slide support device 70 is assembled, the locating member 220 extends into the locating slot 103, thereby facilitating the location of the slide support 200 relative to the cover 100.
