Description

Support assembly for phase shifter and phase shifter

Technical Field

The present disclosure relates to the field of communication antennas, and more particularly, to a support assembly for a phase shifter and a phase shifter including the same.

Background

The antenna phase shifters, which are relatively common in the existing market, can be divided into two categories: one is a section cavity phase shifter, which is designed in an air strip line mode; another type is an arcuate printed circuit board phase shifter.

Whichever structural design is adopted, the manufacturing and production cost is higher, because the structure is more complex and the number of parts is more, and the defects further increase the assembly working hours and bring high cost. Therefore, there is a need to develop a low-cost phase shifter for improving market competitiveness.

In addition, the conventional phase shifter assembly is designed by using a metal base plate. At this time, the printed circuit board and the metal base plate are adhered by a double-sided adhesive tape and fixed by means of rivets. If the printed circuit board has the problems of copper leakage and the like, the ground layer of the printed circuit board is in poor contact with the metal bottom plate, so that the risk of poor passive intermodulation PIM is caused, and the defect of poor reliability of the passive intermodulation PIM is caused.

Moreover, the existing products in the market, no matter the cavity phase shifter or the printed circuit board arc phase shifter, have a larger design size. Due to the requirement of customers, the antennas need to integrate various frequency bands, and therefore, when the size of the phase shifter is too large, many antenna products have the situation that the layout is difficult or the antenna cannot be used. Therefore, it is important to develop a phase shifter with small volume and easy and flexible installation.

Disclosure of Invention

In view of the deep understanding of the problems in the background art, that is, the supporting components of the existing phase shifters are all made of metal substrates, there is a risk of poor passive intermodulation performance due to copper leakage. In order to solve the above technical problem, the inventor of the present disclosure proposes a technical solution to reduce the cost of the product and simultaneously improve the passive intermodulation performance.

In particular, the support member used in the phase shifter according to the present disclosure is made of an insulating material, and compared to a metal substrate, the structure of the support member made of an insulating material can greatly reduce the cost and miniaturize the size of the phase shifter product, thereby enhancing the market competitiveness of the product, and simultaneously optimize the structural size of the product to facilitate flexible layout of the phase shifter in the antenna in which the phase shifter is installed. Moreover, because the supporting component is supported by the insulating material, metal contact with the bottom plate is avoided, so that the risk of poor passive intermodulation PIM caused by a copper leakage problem is eliminated.

In particular, a first aspect of the present disclosure proposes a support assembly for a phase shifter, the support assembly comprising:

a support body, at least one side of which is configured to receive a printed circuit board of the phase shifter; and

at least two support feet configured on either side of the support body,

the support body is fixedly mounted on an object to be mounted on the phase shifter through the at least two support legs.

Compared with the commonly used supporting assembly for the phase shifter in the market, the supporting assembly provided by the disclosure can be vertically arranged in the base station antenna through the two supporting legs, so that the layout space in the base station antenna is saved, the size of the supporting assembly is small, the layout is flexible, and the antenna layout problem is effectively eliminated.

In one embodiment according to the present disclosure, the support body is made of an insulating material comprising plastic. In this manner, material costs can be reduced and material accessibility can be improved, facilitating the production and manufacture of support assemblies according to the present disclosure. In addition, because the supporting main body of the supporting component is made of insulating materials, the problem of contact between the ground layer of the printed circuit board and the supporting main body is solved, the passive intermodulation risk caused by contact is eliminated, and the risk of passive intermodulation failure can be reduced.

In one embodiment according to the disclosure, a fixed cantilever is further configured on the support body, the fixed cantilever being configured at an end remote from the support foot and configured for fixing a drive assembly for driving the phase shifter. Preferably, in one embodiment according to the present disclosure, the fixed cantilever includes a fixed aperture configured to receive an end of the drive assembly.

Preferably or additionally, in one embodiment according to the present disclosure, the support body further comprises a cable fixing member configured to receive a cable for transmitting signals. The support assembly according to the present disclosure can integrate many material parts, such as cable fixing members, so that the use of materials can be reduced and the time for installation can be saved, thereby reducing the time required for assembling and debugging by operators. Preferably, in one embodiment according to the present disclosure, the cable comprises a coaxial cable. More preferably, in one embodiment according to the present disclosure, the cable fixing member and the support body are integrally formed.

Preferably, in an embodiment according to the present disclosure, the at least two supporting feet extend in a direction perpendicular to the supporting body. More preferably, in one embodiment according to the present disclosure, the support assembly includes four support feet including two support feet configured at both sides of the support body, respectively.

Furthermore, a second aspect of the present disclosure proposes a phase shifter, including:

the support assembly set forth in accordance with a first aspect of the present disclosure;

at least one printed circuit board including a first printed circuit board, wherein the first printed circuit board is disposed on one side of the support assembly and includes traces for phase shifting;

a first slider configured to slide on the traces to effect phase shifting; and

a drive assembly configured to drive the first slider to slide on the first printed circuit board.

The phase shifter including the support member can realize a double-sided layout, thereby reducing the size of the phase shifter. In other words, the phase shifter using the support assembly designed according to the present disclosure has a small size, facilitating flexible layout thereof in an antenna, thereby effectively eliminating antenna layout problems.

Preferably, in one embodiment according to the present disclosure, the at least one printed circuit board includes a second printed circuit board, wherein the second printed circuit board is disposed on the other side of the support assembly from the first printed circuit board and includes a trace for phase shifting, and wherein the phase shifter further includes a second slide configured to slide on the trace for phase shifting.

Additionally, in one embodiment according to the present disclosure, the phase shifter further includes a protrusion on the driving assembly, the protrusion configured to fixedly connect the first slide and the second slide.

In one embodiment according to the present disclosure, the driving assembly includes:

a worm mounted on the support body; and

and the driving gear is meshed with the worm and is fixedly connected with the first sliding piece.

a rack; and

and the driving gear is meshed with the rack and is fixedly connected with the first sliding piece.

the pull rod extends out of the bulge on one side facing the sliding sheet; and

Preferably, in an embodiment according to the present disclosure, a through hole is opened at a middle portion of the support body, the through hole being configured to receive a rotation shaft of a vane of the phase shifter.

In summary, the supporting assembly and the phase shifter including the same proposed in the present disclosure can reduce production costs. In particular, the manufacturing cost of the support assembly according to the present disclosure may be reduced by more than 30% compared to the support assembly for phase shifters commonly used in the market. In addition, because the supporting main body of the supporting component is made of insulating materials, the problem of contact between the ground layer of the printed circuit board and the supporting main body is solved, the passive intermodulation risk caused by contact is eliminated, and the risk of passive intermodulation failure can be reduced.

Detailed Description

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof. The accompanying drawings illustrate, by way of example, specific embodiments in which the disclosure can be practiced. The example embodiments are not intended to be exhaustive of all embodiments according to the disclosure. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims.

In view of the deep understanding of the problems in the background art, that is, the supporting components of the conventional phase shifter are all tiled, have a large volume, and are all made of metal bottom plates, there is a risk of poor passive intermodulation performance due to copper leakage. In order to solve the above technical problems, the inventors of the present disclosure propose a technical solution to reduce the cost of the product and simultaneously improve the passive intermodulation performance.

Particularly, the support assembly adopted by the phase shifter according to the disclosure is vertically arranged in the base station antenna through two support legs, so that the layout space in the base station antenna is saved, the support assembly is small in size and flexible in layout, and the problem of antenna layout is effectively solved. Made of an insulating material, the support member structure made of an insulating material can greatly reduce the cost and miniaturize the size of the phase shifter product, compared to a metal chassis, thereby enhancing market competitiveness of the product, and simultaneously optimizing the structural size of the product to facilitate flexible layout of the phase shifter in an antenna in which the phase shifter is mounted. Moreover, because the supporting component is supported by the insulating material, metal contact with the bottom plate is avoided, so that the risk of poor passive intermodulation PIM caused by a copper leakage problem is eliminated.

A support assembly and a corresponding phase shifter disclosed according to the present disclosure will be described below with reference to fig. 1 to 6. In which fig. 1 illustrates a schematic view of a support assembly 100 according to one embodiment of the present disclosure, and fig. 2-4B illustrate various views of a phase shifter 200 according to one embodiment of the present disclosure. Furthermore, fig. 5 shows a schematic diagram of a phase shifter 500 according to another embodiment of the present disclosure, and fig. 6 shows a schematic diagram of a phase shifter 600 according to yet another embodiment of the present disclosure.

As shown in fig. 1, a first aspect of the present disclosure provides a support assembly 100 for a phase shifter, where the support assembly 100 includes a support body 110 and at least two support legs 120 disposed at two sides of the support body 110, where at least one side of the support body 110 is configured to receive a printed circuit board (not shown in fig. 1, and will be described below with reference to fig. 2) of the phase shifter, and the at least two support legs 120 are configured at two sides of the support body 110 (i.e., the other side not visible in fig. 1 may also have the presence of the support legs 120), so that the support assembly 100 may be vertically arranged in a base station antenna through the at least two support legs 120, and the layout is flexible. Here, the support body 110 may alternatively be plate-shaped, for example. Furthermore, the support body 110 is made of an insulating material (e.g. plastic or other prefabricated material) and the support body 110 is fixedly mounted to an object to which the phase shifter is to be mounted (e.g. another plate-shaped member) via the at least two support feet 120. It can be seen that the support assembly 100 proposed according to the present disclosure can be manufactured at a reduced cost compared to the support assemblies for phase shifters commonly used in the market. In addition, since the supporting body 110 of the supporting assembly 100 is made of an insulating material, the problem of contact between the printed circuit board ground layer mounted on the supporting body 110 and the supporting body 110 is solved, so that the risk of passive intermodulation caused by contact is eliminated, and the risk of poor passive intermodulation can be reduced.

In addition to the above-mentioned components, it can be seen from fig. 1 that the support assembly 100 according to the present disclosure further comprises a cable fixing member 130, said cable fixing member 130 can be configured, for example, as a cable clip configured to receive a cable for transmitting signals. As can be seen from fig. 1, the bottom left-most cable may be a thicker cable clamp, which may for example be used for fixing input signal lines, while the other nine (nine on the front side, not counting on the reverse side) cables 140 may for example be used for output signal lines, such as output cables for signals processed by phase shifters. The support assembly 100 according to the present disclosure can integrate many material parts, such as the cable fixing member 130, thereby reducing the material usage and saving the installation time (i.e., the operator does not need to install an additional cable clamp, and inevitably can reduce the installation time), and further reducing the time required for the operator to assemble and debug. Preferably, in one embodiment according to the present disclosure, the cable 140 includes a coaxial cable. More preferably, in one embodiment according to the present disclosure, the cable fixing member 130 and the support body 110 are integrally formed.

It should be understood by those skilled in the art that the cable fixing member 130 is not necessary here, that is, the support assembly 100 according to the present disclosure including the cable fixing member 130 is a preferred implementation form and not necessarily the support assembly according to the present disclosure. Furthermore, it is preferable, but not necessary, that the cable fixing member 130 and the support body 110 are integrally formed.

Furthermore, although two support feet 120 are shown, it is not intended that support assembly 100 according to the present disclosure include only two support feet 120 or necessarily two support feet 120. In contrast, support assembly 100 according to the present disclosure may include either one foot 120 on each side of support body 110, e.g., disposed in a middle position of support body 110, three feet 120, e.g., spaced apart (i.e., one foot 120 on the opposite side is disposed between two feet 120 on the front side, or more feet 120.

In addition to the implementation form shown in fig. 1, the support assembly according to the present disclosure can have other implementation forms, and another implementation form of the support assembly according to the present disclosure, and the phase shifter 200 including the support assembly of the implementation form will be described below with the aid of fig. 2 to 4B. In which fig. 2 illustrates a perspective exploded view of a phase shifter 200 according to one embodiment of the present disclosure, fig. 3 illustrates a schematic view of a slide structure of the phase shifter 200 according to the present disclosure, fig. 4A illustrates a front view of the phase shifter 200 according to the present disclosure, and fig. 4B illustrates a rear view of the phase shifter 200 according to the present disclosure.

As can be seen from fig. 2 to 4B, the phase shifter 200 proposed by the first aspect of the present disclosure includes the support member 100' and other components of the phase shifter, such as a printed circuit board and a driving member for driving the phase shift of the phase shifter. Wherein the support assembly 100' comprises a support body 110' and at least two support feet 120', wherein the support body 110' may optionally be, for example, plate-shaped and at least one side of the support body 110' is configured to receive the printed

circuit boards

202, 204 of the phase shifter, and the at least two support feet 120' are configured at two sides of the support body 110', and the support assembly may be vertically arranged in the base station antenna through the two support feet, thereby saving layout space in the base station antenna and providing more flexibility in layout. In this case, the support body 110' is made of an insulating material (e.g., plastic or another prefabricated material) and the support body 110' is fixedly attached to the object to which the phase shifter 200 is to be attached via the at least two support feet 120'. It can be seen that the support assembly 100' proposed according to the present disclosure has a reduced manufacturing cost compared to the support assemblies for phase shifters commonly used in the market. In addition, since the supporting body 110 'of the supporting assembly 100' is made of an insulating material, the problem of contact between the ground layers of the printed circuit board 202 and the printed circuit board 204 mounted on the supporting body 110 'and the supporting body 110' is solved, so that the risk of passive intermodulation caused by contact is eliminated, and the risk of poor passive intermodulation can be reduced. Here, the insulating material comprises plastic. In this manner, material costs can be minimized and material accessibility can be improved, facilitating the production and manufacture of support assemblies according to the present disclosure.

In addition to the above-mentioned components, it can be seen from fig. 2 that the support assembly 100' according to the present disclosure further includes a cable fixing member 130', which cable fixing member 130' can be configured, for example, as a cable clip configured to receive a cable for transmitting signals. As can be seen from fig. 1, the leftmost lower corner may be a thicker cable clamp, which may for example be used for fixing input signal lines, while the other nine (nine on the front side, not counting on the back side) cables 140' can for example be used for output signal lines, such as output cables for signals processed by phase shifters. The support assembly 100 'according to the present disclosure can integrate many material parts, such as the cable fixing member 130', thereby reducing the material usage and saving the installation time (i.e., the operator does not need to install an additional cable clamp, and thus the installation time can be reduced), and further reducing the time required for the operator to assemble and debug. Preferably, in one embodiment according to the present disclosure, the cable 140' comprises a coaxial cable. More preferably, in an embodiment according to the present disclosure, the cable fixing member 130 'and the supporting body 110' are integrally formed, so that the use of some parts for fixing is reduced, and the cost is saved.

It should be appreciated by those skilled in the art that the cable fixing member 130' is not necessary here, that is, the support assembly 100' according to the present disclosure including the cable fixing member 130' is a preferred implementation form and not necessary to implement the support assembly according to the present disclosure. Furthermore, it is preferable that the cable fixing member 130 'and the supporting body 110' are integrally formed, but this is not necessarily the case.

Moreover, although two support feet 120 'are shown, it is not intended that support assembly 100' according to the present disclosure include only two support feet 120 'or necessarily two support feet 120'. In contrast, support assembly 100 'according to the present disclosure can include either one support foot 120' on each side of support body 110', e.g., disposed at a middle position of support body 110', or three support feet 120', e.g., spaced apart, or having more support feet 120'.

In addition to the above-described components, the phase shifter 200 according to the present disclosure includes other components, for example, in the embodiment shown in fig. 2, a fixed cantilever 140 is configured on the support body 110', the fixed cantilever 140 is configured at an end (shown as an upper end in the embodiment shown in fig. 2) far from the support foot 120' and is configured to fix a driving assembly (for example, a worm 201) for driving the phase shifter. Preferably, in an embodiment according to the present disclosure, the fixed cantilever 140 includes a fixed aperture 141, and the fixed aperture 141 is configured to receive an end 2011 of the driving assembly 201.

The support assembly for a phase shifter proposed in the present disclosure adopts a vertical structure, which uses an insulating material such as plastic for the support body 100', so that it is possible to avoid the risk of occurrence of passive intermodulation due to the erroneous contact of the printed

circuit board

202 or 204 mounted thereon with a metal substrate.

Alternatively, a plastic-integrated cable clamp can be used to secure the main feeder (thicker cable in the figure) and the phase cable (thinner cable in the figure). The sector gear 203 and the pressing piece 205 on the other side in the phase shifter are driven by a worm or a rack, so that the phase angle is changed. The positive and negative polarization components of the phase shifter 200 are respectively fixed on both sides of the support body 110' and are pre-coupled by a sector gear, a central rotation shaft 206 and a nut 207. Here, one side of the phase shifter 200 is a driving end (e.g., the front side shown in fig. 2), and the other side (e.g., the back side shown in fig. 2) is a linkage end, and the middle is matched through the pin hole 208 to realize a transmission process.

The printed circuit boards 202 are fixed to the support body 110' of the support assembly 100' by rivets 209, wherein the rivets 209 penetrate the two printed

circuit boards

202 and 204 and the support body 110', respectively, to achieve the fixing effect. The sector gear 203 and the sliding piece 213 are fixed to one side of the support body 110' of the support assembly 100' of the phase shifter 200 by the central rotation shaft 206, and are fixed to the other side of the support body 110' of the support assembly 100' of the phase shifter 200 by the pressing piece 205 and the sliding piece 215 on the other side of the support body 110', and the elastic nut 207 performs a pre-tightening function with the central rotation shaft 206 by a screw thread. The sector gear 203 can be configured, for example, as a helical gear, above which the drive function is achieved by forming a mechanical rotational fit with a portion of the drive assembly, such as the worm 201. One end of the worm 201 is fitted into the fixing hole 141 of the fixing cantilever 140 of the support assembly 100', and the other end of the worm 201 is engaged through the auxiliary support 218, thereby limiting the axial displacement of the worm 201. The auxiliary support base 218 is fixed to the support body 110 'of the support assembly 100' by rivets. The cable is secured within the resilient catch of the support body 110 'of the support assembly 100' thereby restricting movement of the cable.

Preferably, in an embodiment according to the present disclosure, the at least two supporting feet 120 'extend in a direction perpendicular to the supporting body 110'. That is, for example, in the embodiment shown in fig. 2, the extending direction of the two supporting legs 120 'is, for example, the horizontal direction, and in this case, the extending direction of the supporting main body 110' is, for example, the vertical direction. More preferably, in one embodiment according to the present disclosure, the support assembly includes four support feet 120', and the four support feet 120' include two support feet 120 'respectively configured at both sides of the support main body 110'. That is, there are two support feet 120 'on the front side of support body 110', and two support feet 120 'on the back side of support body 110'.

In summary, the phase shifter 200 proposed according to the present disclosure comprises the above-described support assembly 100 'and at least one printed circuit board (e.g., the printed circuit board 202 and the printed circuit board 204 of fig. 2) including a first printed circuit board 202, wherein the first printed circuit board 202 is disposed on a front side of the support assembly 100' and includes traces for shifting phase. Furthermore, the phase shifter 200 proposed according to the present disclosure includes a first slider 213, the first slider 213 being configured to slide on the trace to achieve phase shifting. Furthermore, the phase shifter 200 according to the present disclosure further includes a driving assembly configured to drive the first slide 213 to slide on the first printed circuit board 202.

Further, in one embodiment according to the present disclosure, the at least one printed circuit board comprises a second printed circuit board 204, wherein the second printed circuit board 204 is disposed on the other side of the support assembly 100' from the first printed circuit board 202 and comprises traces for phase shifting, and wherein the phase shifter 200 further comprises a second slide 215, the second slide 215 being configured to slide on the traces for phase shifting. In order to achieve the interlocking of the first and

second slide plates

213 and 215, the phase shifter 200 further includes a fixing member configured to fixedly connect the first and

second slide plates

213 and 215.

FIG. 3 shows a schematic view of a slider structure of a phase shifter 200 according to the present disclosure. As can be seen in fig. 3, the first slides 213 each have a recess at the top thereof, which is configured to receive a projection 2031 of the sector gear 203 for driving, so that the first slides 213 can move synchronously with the movement of the sector gear 203. In addition, the second sliding piece 215 is linked with the pressing piece 205 through hole pin fitting, and then the pressing piece 205 is linked with the sector gear 203 through pin fitting. Therefore, the first slide plate 213 and the second slide plate 215 can be driven by one sector gear 203 to move synchronously, and the phase shifting operation of the phase shifter can be realized. As can also be seen in connection with fig. 2, the positive fit of the projection 2031 and the recess will extend beyond the top of the support body 110' of the support assembly 100' when assembled, such that the support body 110' does not obstruct the movement of the first and

second slides

213, 215 and the sector gear 203. Further, in order to facilitate the movement of the first and

second slips

213 and 215 and the sector gear 203, the top of the support main body 110' of the support assembly 100' is configured in an arc shape such that the first and

second slips

213 and 215 can be moved synchronously along the top of the support main body 110' following the movement of the sector gear 203 after being assembled.

Fig. 4A shows a front view of a phase shifter 200 according to the present disclosure, and fig. 4B shows a back view of the phase shifter 200 according to the present disclosure. As can be seen in fig. 4A and 4B, the driving assembly comprises a worm 201 and a driving gear 203, the worm 201 being mounted on the supporting body 110' and the driving gear 203 being in mesh with the worm 201 and being fixedly connected to the first slide 213.

Fig. 5 shows a schematic diagram of a phase shifter 500 according to another embodiment of the present disclosure. As can be seen in fig. 5, the driving assembly comprises: the rack 501 may be mounted on the support body, or may be fixed by another component, that is, the rack may be further restricted from being engaged with the driving gear 503 by adding another component; and a driving gear 503, wherein the driving gear 503 is meshed with the rack 501 and is fixedly connected with the first sliding piece. Preferably, in an embodiment according to the present disclosure, a through hole is opened at a middle portion of the support body, the through hole being configured to receive a rotation shaft of a vane of the phase shifter. In this way, the phase shifter 200 including the support member 100' is enabled to realize a double-sided layout, thereby reducing the size of the phase shifter 200. In other words, the phase shifter 200 employing the support assembly 100' designed according to the present disclosure is small in size, facilitating flexible layout thereof in an antenna, thereby effectively eliminating antenna layout problems.

Fig. 6 shows a schematic diagram of a phase shifter 600 according to yet another embodiment of the present disclosure. As can be seen from fig. 6, the driving assembly of fig. 6 includes a pull rod 601, and the pull rod 601 can be fixed on the supporting body, or can be driven by adding other parts to limit the matching of the pull rod and the driving assembly 603. On the side of the tie rod 601 facing the slide a projection (not shown) projects which in the assembled state can be received in a recess of a drive element 603, such as a drive gear. Under the condition of moving to complete the phase shifting of the phase shifter, the pull rod 601 is pulled left and right, and the sliding sheet is driven to slide through the matching of the protrusion and the groove of the pull rod, so that the phase shifting function of the phase shifter is realized.
