In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments.

A filter is widely used in the field of communications as a frequency selection device, and is used to select a communication signal and filter out clutter or interference signals outside the frequency of the communication signal, that is, a useful signal can pass through the filter without attenuation as much as possible, and a useless signal can be attenuated as much as possible. In order to connect with an external device to transmit signals, a connector is generally provided. The connector is usually electrically connected to a signal transmission member (a structural member for transmitting a signal) of the filter, so as to realize signal conduction between the connector and the signal transmission member.

However, in some cases, when the filter is subjected to an external force (e.g., vibration during manufacturing or use), relative movement or looseness may occur between the connector and the signal transmission member, so that signal transmission between the connector and the signal transmission member is unstable, and normal operation of the filter is affected.

Based on this, in order to improve the technical problem that the signal transmission between the connector and the signal transmission member is unstable, the inventor proposes the following scheme.

Referring to fig. 1 to fig. 3, the present embodiment provides a signal transmission device 100, and the signal transmission device 100 can be applied to various types of filters for signal transmission. The signal transmission assembly 100 includes a signal transmission member 10, a support base 20 and a connector 30, wherein:

the signal transmission member 10 is a structural member capable of transmitting a signal, and may be, for example, a printed circuit board (also referred to as a printed circuit board or a PCB), a power amplifier board, a sheet metal resonator, a coupling plate, a tap plate, a connecting plate, a low-pass plate, or the like, but is not limited thereto. The signal transmission member 10 may have various shapes, such as a plate-like structure or a sheet-like structure, but may have other regular or irregular shapes. Fig. 1 to 3 schematically show a case where the signal transmission member 10 is a printed wiring board.

The support base 20 is fixedly disposed on the signal transmission member 10, that is, the position of the support base 20 is fixed relative to the position of the signal transmission member 10. It is understood that the support base 20 can be fixed to the signal transmission member 10 by various fixing means, such as welding, plugging, clipping, riveting, crimping, screwing, fastening, etc., but not limited thereto. The supporting base 20 is provided with a first through hole 201, and the first through hole 201 can be used for installing the connector 30. It is understood that the supporting base 20 may be a structure with various shapes, such as a block structure with regular or irregular shapes, as long as the first through hole 201 can be opened for the installation of the connector 30, and the supporting base 20 may be specifically arranged according to the installation requirement of the connector 30 and the fixing manner of the supporting base 20 on the signal transmission element 10, which is not limited in this embodiment of the present invention.

The connector 30 is a carrier for transmitting signals, and can be used to connect with an external device to transmit signals of the external device to the signal transmission member 10, or transmit signals of the signal transmission member 10 to the external device, which may also be referred to as a radio frequency connector. It is understood that the connector 30 may be various types of connectors applied to the filter, such as BMA connector (blind mate connector), SMA connector, SMP connector, MBX connector, PSMP connector, TX connector, etc., but is not limited thereto.

The connector 30 is disposed in the first through hole 201, and the connector 30 may be disposed in the first through hole 201 in various ways, for example, but not limited to, the connector 30 may be screwed, interference fit, snap fit, etc. with the first through hole 201. Fig. 3 shows, by way of example, the connector 30 in threaded engagement with the first through hole 201, in which case at least part of the inner wall of the first through hole 201 is provided with an internal thread. The connector 30 is electrically connected to the signal transmission member 10, that is, the connector 30 is in signal conduction with the signal transmission member 10.

As can be seen from the above, in the signal transmission assembly 100 provided in the embodiment of the present disclosure, since the supporting base 20 is fixedly disposed on the signal transmission element 10, that is, the supporting base 20 is fixed relative to the signal transmission element 10, and the connector 30 is disposed in the first through hole 201 of the supporting base 20 and electrically connected to the signal transmission element 10, the supporting base 20 can provide stable support for the connector 30, so as to improve the stability of the relative position between the connector 30 and the signal transmission element 10, and reduce the possibility that the connector 30 moves or loosens relative to the signal transmission element 10, thereby improving the stability of signal transmission between the connector 30 and the signal transmission element 10, and further improving the stability of the filter during operation.

In addition, by changing the height of the supporting base 20, the distance or relative height between the end of the connector 30 opposite to the signal transmission member 10 and the signal transmission member 10 can be changed, without affecting the structural design or position setting of the signal transmission member 10, which is beneficial to improving the flexibility.

In some embodiments, referring to fig. 2, fig. 3 and fig. 5, the supporting base 20 is provided with an inserting portion 211, the signal transmission element 10 is provided with an inserting mating portion 111, and the inserting portion 211 is inserted and mated with the inserting mating portion 111.

It is understood that the mating means that the protruding structure is inserted into the recessed structure, so that one of the

mating parts

211 and 111 is a protruding structure (such as, but not limited to, a convex column, a protrusion, a bump, etc.), and the other is a recessed structure (such as, but not limited to, a groove, a through hole, a blind hole, etc.). Fig. 3 and 5 show the case where the insertion part 211 is a convex column and the insertion fitting part 111 is a through hole. The shape of the cross section (the section perpendicular to the projection direction) of the projection structure may be circular or non-circular, wherein the non-circular shape may be an ellipse, a polygon, etc., but is not limited thereto; the cross-section of the recessed structures (the section perpendicular to the direction of the recess) may have a shape that is adapted to the shape of the protruding structures.

With such an arrangement, the insertion portion 211 and the insertion mating portion 111 are inserted and mated with each other, so that the support base 20 can be positioned on the signal transmission member 10, the support base 20 can be conveniently and rapidly mounted, and the consistency of the relative positions of the support base 20 and the signal transmission member 10 of each signal transmission assembly 100 can be improved. In addition, when the inserting portion 211 is in interference fit with the inserting fitting portion 111, the supporting base 20 can be fixed on the signal transmission member 10.

Optionally, referring to fig. 5, the number of the insertion parts 211 and the number of the insertion matching parts 111 may be multiple, and the insertion parts 211 and the insertion matching parts 111 are arranged in a one-to-one correspondence manner. Thus, the positioning accuracy of the support base 20 on the signal transmission member 10 and the stability of the support base 20 in cooperation with the signal transmission member 10 can be further improved.

Of course, in other embodiments, the number of the inserting portion 211 and the inserting mating portion 111 may be one, and the positioning or fixing of the supporting seat 20 can also be realized. In this case, when the cross-sectional shapes of the insertion part 211 and the insertion fitting part 111 are both non-circular, the support seat 20 can be positioned more favorably.

In some embodiments, referring to fig. 2, fig. 4 and fig. 5, the supporting base 20 is provided with a connecting hole 202, the signal transmission element 10 is provided with a second through hole 101, a position of the second through hole 101 corresponds to a position of the connecting hole 202, that is, a projection of the supporting base 20 in a direction toward the signal transmission element 10, the second through hole 101 and the connecting hole 202 coincide or have substantially the same position, and can be communicated when the second through hole 101 and the connecting hole 202 are not blocked by other components. The signal transmission assembly 100 further includes a fastener 40, and the fastener 40 is disposed through the second through hole 101 and connected to the connection hole 202.

It is understood that the fasteners 40 can be various types of fastening structures such as, but not limited to, screws, bolts, rivets, pins, and the like. The connection hole 202 may be a light hole or a threaded hole, and may be adapted according to the type of the fastener 40 to facilitate connection with the fastener 40.

By such arrangement, the fastener 40 can be inserted into the second through hole 101 and connected to the connection hole 202, so as to fix the support base 20 and the signal transmission member 10, and the installation is convenient.

By such arrangement, not only is the installation and fixation between the supporting seat 20 and the signal transmission piece 10 convenient, but also the supporting seat 20 and the signal transmission piece 10 can be detached, and the replacement or maintenance is convenient.

Optionally, referring to fig. 4 and 5, a washer 60 may be disposed between the screw head of the screw or the bolt head of the bolt and the signal transmission member 10, so as to reduce the possibility of loosening the screw or the bolt head, and to improve the stability of the fit among the fastening member 40, the supporting seat 20 and the signal transmission member 10. Wherein the washer 60 may include at least one of a flat washer and a spring washer.

In other embodiments, the supporting base 20 is welded to the signal transmission element 10 to achieve a fixed connection between the supporting base 20 and the signal transmission element 10. It is understood that the supporting base 20 and the signal transmission member 10 can be welded by various welding methods, such as solder paste welding, laser welding, etc., but not limited thereto. In this case, the support base 20 and the signal transmission member 10 may not be fixed by the fastener 40, and may be fixed by the fastener 40.

In some embodiments, referring to fig. 3 to fig. 5, the signal transmission member 10 is provided with a third through hole 102, a position of the third through hole 102 corresponds to a position of the first through hole 201, that is, a projection of the supporting base 20 in a direction toward the signal transmission member 10, the third through hole 102 and the first through hole 201 are coincident or substantially the same in position, and can be communicated when the third through hole 102 and the first through hole 201 are not blocked by other components. The connector 30 includes an inner core 31 and an inner conductor 32 connected to the inner core 31, the inner core 31 and the inner conductor 32 may be located in the first through hole 201, and the inner conductor 32 is inserted into the third through hole 102 and electrically connected to the signal transmission member 10.

Of course, in some other embodiments, the connector 30 may not be provided with the inner conductor 32, and the inner core 31 of the connector 30 is inserted into the third through hole 102 and electrically connected to the signal transmission member 10.

It is to be understood that the different types of connectors 30 differ in their construction and, for ease of understanding, will be described below by way of example. Illustratively, the connector 30 may include an outer shell 34, an inner core 31 inside the outer shell 34, the material of the inner core 31 being typically a conductor material capable of transmitting signals, and an insulating medium 35 disposed between the outer shell 34 and the inner core 31 to insulate the outer shell 34 from the inner core 31. The connector 30 can be disposed in the first through hole 201 through the outer housing 34. The material of the outer housing 34 may be a conductive material; of course, the material of the outer housing 34 may also be an insulating material, in which case the outer housing 34 and the insulating medium 35 may be an integral structure.

In some cases, the connector 30 may further include an inner conductor 32, and the inner conductor 32 may be electrically connected to the inner core 31 and may function to elongate the inner core 31 to facilitate electrical connection of the inner core 31 to the signal transmission member 10 via the inner conductor 32.

Optionally, the inner core 31 or the inner conductor 32 of the connector 30 may be soldered to the signal transmission member 10 to improve the reliability of the electrical connection between the connector 30 and the signal transmission member 10.

In some embodiments, referring to fig. 3 to 5, the supporting base 20 is an integrated structure, a plurality of first through holes 201 may be disposed on the supporting base 20, a plurality of connectors 30 may also be disposed, and the connectors 30 and the first through holes 201 are disposed in a one-to-one correspondence.

So set up, compare in each connector 30 all adopt an independent supporting seat, occupation space is littleer, can improve compact structure degree, and then can improve the space utilization of wave filter.

Of course, in other embodiments, only one first through hole 201 may be provided on one support base 20 for mounting one connector 30.

In the above embodiment, the supporting base 20 may be disposed on the signal transmission member 10 by means of inserting, welding, fastening, etc., but the connection between the supporting base 20 and the signal transmission member 10 is not limited thereto.

In other embodiments, referring to fig. 6 to 9, the signal transmission member 10 includes a first side 1001 and a second side 1002 opposite to each other, and the signal transmission member 10 is provided with a fourth through hole 103 penetrating through the first side 1001 and the second side 1002. The support base 20 comprises a main body 21 and a protruding portion 22, wherein the main body 21 is located on the first side 1001 and abuts against the signal transmission piece 10; protrusion 22 is connected to body 21, and protrusion 22 passes through fourth through hole 103 from first side 1001 and extends to second side 1002. The signal transmission assembly 100 further includes a locking member 50, wherein the locking member 50 is located on the second side 1002 and is fixedly connected to the protruding portion 22.

It is understood that the body portion 21 and the protrusion 22 may be structures of various shapes, such as a cylindrical structure, a columnar structure, a rod-like structure, etc., but not limited thereto. Since the main body 21 is located on the first side 1001 and abuts against the signal transmission member 10, and the protrusion 22 passes through the fourth through hole 103 from the first side 1001 and extends to the second side 1002, a step structure is formed between the protrusion 22 and the main body 21. The main body 21 and the protruding portion 22 may be integrally formed, or may be separately formed and connected.

It will be appreciated that retaining member 50 can be fixedly coupled to protrusion 22 in a variety of ways, such as, but not limited to, a threaded connection, a snap-fit connection, a resilient connection, and the like. The retaining member 50 can be any shape of structure that can retain the support base 20 on the second side 1002.

So set up, through retaining member 50 and protruding portion 22 fixed connection, main part 21 is at first side 1001 butt signal transmission spare 10, and retaining member 50 is at second side 1002 butt signal transmission spare 10 promptly, can carry out spacingly respectively to supporting seat 20 in the relative both sides of signal transmission spare 10, can install supporting seat 20 and signal transmission spare 10 mutually fixedly, and it is convenient to install.

Alternatively, in some embodiments, referring to fig. 8 and 9, protrusion 22 includes a transition section 221 connected to body portion 21 and a connecting section 222 connected to transition section 221, and the outer perimeter of the cross section of connecting section 222 is smaller than the outer perimeter of the cross section of transition section 221. The transition section 221 is located in the fourth through hole 103, and the connection section 222 extends to the second side 1002. Retaining member 50 is fixedly attached to connecting section 222.

It is understood that the cross section of the connecting section 222 refers to a section of the connecting section 222 perpendicular to the direction pointing to the connecting section 222 along the transition section 221, and the outer circumference of the cross section of the connecting section 222 refers to the circumference of the outer edge of the cross section of the connecting section 222, and the circumference refers to the length of one circle of the closed figure. Likewise, the cross section of the transition section 221 refers to a section of the transition section 221 perpendicular to a direction along the transition section 221 toward the connection section 222, and an outer circumference of the cross section of the transition section 221 is a circumference of an outer edge of the cross section of the transition section 221. Since the outer circumference of the cross section of the connecting section 222 is smaller than that of the transition section 221, a step structure is formed between the connecting section 222 and the transition section 221. The peripheral edge of the cross section of the connecting section 222 can be circular or non-circular, and the peripheral edge of the cross section of the transition section 221 can be circular or non-circular; when the peripheral edge of the cross section of the connection section 222 and the peripheral edge of the cross section of the transition section 221 are both circular, the outer diameter of the connection section 222 (the maximum diameter of the periphery of the connection section 222) is smaller than the outer diameter of the transition section 221 (the maximum diameter of the periphery of the transition section 221).

So set up, because the outer girth of following of the cross section of linkage segment 222 is less than the outer girth of following of the cross section of changeover portion 221, be difficult for taking place mutual interference with the inner wall of fourth through-hole 103 when making linkage segment 222 wear to establish fourth through-hole 103, and changeover portion 221 is located fourth through-hole 103, can play the positioning action, do benefit to and reduce the clearance between the lateral wall of changeover portion 221 and the inner wall of fourth through-hole 103, and then reduce the possibility that takes place relative movement between changeover portion 221 and the fourth through-hole 103, do benefit to and improve supporting seat 20 and signal transmission piece 10 fixed connection's stability.

Alternatively, in some embodiments, referring to fig. 7-9, the locking member 50 is a nut member, i.e., a structural member having a threaded bore, which may be a standard nut or a non-standard nut. The nut member is threadedly engaged with the projection 22, and the projection 22 is provided with external threads for threadedly engaging the nut member.
