Description

Technical Field

[0001] The present invention relates to an RF connector and a communication device including the same.

Background Art

[0002] The content described in this section merely provides background information of the present disclosure and does not constitute prior art.

[0003] In general, an RF connector is used to receive RF (Radio Frequency) signals between printed circuit boards (PCBs, Printed Circuit Boards). RF connectors include single connectors that transmit a single frequency signal and multi-connectors that transmit various signals in different frequency bands. Recently, multi-connectors are frequently used to process signals in various frequency bands.

[0004] However, connectors for transmitting frequency signals occupy a large volume. Due to the structure and function of the connectors, in order to connect various printed circuit boards, a height difference occurs between the printed circuit boards, resulting in an increase in the overall size of the device.

[0005] In addition, there is a limit to the range of frequency bands that a connector can process. In order to transmit signals in a large number or wide range of frequency bands using connectors, the unit price of components increases as a whole.

[0017] Hereinafter, some embodiments of this disclosure will be described in detail using illustrative drawings. Note that when assigning reference numerals to components in each drawing, efforts have been made to ensure that identical components have the same reference numeral whenever possible, even when shown in different drawings. Furthermore, in describing this disclosure, if a detailed explanation of a related known configuration or function is deemed to obscure the gist of this disclosure, such detailed explanation will be omitted.

[0018] In describing the components of the present invention, terms such as 1st, 2nd, A, B, (a), (b), etc., may be used. Such terms are used solely to distinguish a component from other components, and do not limit the essence, order, or sequence of the component in question.

[0019] When it is stated that one component is “linked,” “joined,” or “connected” to another component, please understand that this means that the component is directly connected to or connected to the other component, but that other components may also be “linked,” “joined,” or “connected” between each component.

[0020] When a specification states that a part "includes" or "companies" a certain component, unless otherwise stated, this means that it may include other components rather than excluding them.

[0021] Terms such as "...part" and "module" as used in the specification mean a unit that processes at least one function or operation, which is embodied in hardware, software, or a combination of hardware and software.

[0022] Unless otherwise stated, it should be made clear that the description relating to one embodiment may also apply to the other embodiments.

[0023] The description of the invention disclosed below, along with the accompanying drawings, is intended to illustrate exemplary embodiments of the invention and not to show the only embodiments in which the invention is carried out.

[0024] Figure 1 is an exploded perspective view showing a part of the configuration of a communication device according to one embodiment of the present disclosure.

[0025] Figure 2a is a cross-sectional view of a part of a communication device according to one embodiment of the present disclosure, showing the case in which a printed circuit board is not arranged.

[0026] Figure 2b is a cross-sectional view of a part of a communication device according to one embodiment of the present disclosure, illustrating the case in which a printed circuit board is arranged.

[0027] Figure 3 is a perspective view of a part of a communication device according to one embodiment of the present disclosure.

[0028] Referring to Figures 1 to 3, a communication device according to one embodiment of the present invention includes all or part of a mechanical casing 20, a first printed circuit board 10, a second printed circuit board 12, and one or more connectors 300.

[0029] The mechanism casing 20 includes a substrate seating surface 210 on which the first printed circuit board 10 and the second printed circuit board 12 are seated, and one or more connecting grooves 220 formed in the substrate seating surface 210. The mechanism casing 20 is formed from a thermally conductive rigid member, such as an aluminum alloy or a stainless steel alloy.

[0030] In one embodiment of the present invention, the mechanism casing 20 is an external housing configured to form the external appearance of a communication device, support the device structure, and house a printed circuit board. The external housing includes a plurality of heat dissipation fins 21 formed on at least one of its surfaces.

[0031] However, the present invention is not limited thereto, and the mechanism casing 20 is a separate component rather than an external housing, for example, a separate thermally conductive rigid member that supports the printed circuit board between the external housing and the printed circuit board.

[0032] The substrate seating surface 210 includes a first seating surface 212 on which the first printed circuit board 10 is seated, and a second seating surface 214 on which the second printed circuit board 12 is seated. The first seating surface 212 and the second seating surface 214 are formed to have a step difference between them.

[0033] In one embodiment of the present invention, the first printed circuit board 10 and the second printed circuit board 12 have different thicknesses. The size of the step difference between the first seating surface 212 and the second seating surface 214 corresponds to the difference in thickness between the first printed circuit board 10 and the second printed circuit board 12. As a result, the upper surface of the first printed circuit board 10 (the surface opposite to the surface supported by the substrate seating surface 210) and the upper surface of the second printed circuit board 12 (the surface opposite to the surface supported by the substrate seating surface 210) are arranged on the same plane or a plane equivalent thereto.

[0034] Although not shown herein, arranging the first printed circuit board 10 and the second printed circuit board 12 on the same plane is advantageous in reducing or optimizing the overall size and weight of the communication device when arranging any connector 300 that directly connects them, or when arranging filters or other elements that support them or are provided on the top surface.

[0035] One or more connecting grooves 220 are formed within the substrate seating surface 210, for example, multiple grooves are formed along the boundary between the first seating surface 212 and the second seating surface 214.

[0036] The first printed circuit board 10 includes a plurality of devices mounted thereon. In one embodiment of the RF connector of this disclosure, the first printed circuit board 10 is an amplifier board, but is not necessarily limited to this.

[0037] The second printed circuit board 12 is positioned adjacent to and spaced apart from the first printed circuit board 10 on one side of the first printed circuit board 10, and includes a plurality of elements mounted thereon. In an RF connector according to one embodiment of the present disclosure, the second printed circuit board 12 is a digital board, but is not necessarily limited to that.

[0038] One or more connectors 300 are placed in the connecting groove 220 and are configured to electrically connect the first printed circuit board 10 and the second printed circuit board 12.

[0039] Figure 4 is a perspective view showing only the connector of a communication device according to one embodiment of the present disclosure.

[0040] Referring further to Figure 4, the connector 300 includes a support member 310 and an elastic connecting member 320.

[0041] The support member 310 contacts at least a portion of the mechanism housing 20 within the connecting groove 220. The support member 310 is made of an insulating material, which is a high heat-resistant thermoplastic, such as polycarbonate, Lusep, or Teflon®.

[0042] The elastic connecting member 320 is made of a conductive material suitable for transmitting high-frequency signals (RF signals) while possessing elasticity, such as beryllium copper (BeCu) or stainless steel alloy (SUS). The elastic connecting member 320 is positioned between the support member 310, the first printed circuit board 10 and / or the second printed circuit board 12, and is configured to electrically connect the first printed circuit board 10 and the second printed circuit board 12.

[0043] Furthermore, the elastic connecting member 320 includes a plate-shaped base 324, a first side wall 325 formed at one end of the plate-shaped base 324, a first contact portion 326 formed at one end of the first side wall 325, a second side wall 327 formed at the other end of the plate-shaped base 324, and a second contact portion 328 formed at one end of the second side wall 327. The elastic connecting member 320 is formed by bending.

[0044] As explained earlier, the substrate seating surface 210 has a step corresponding to the difference in thickness between the first printed circuit board 10 and the second printed circuit board 12. Furthermore, the lengths (or vertical heights) of the first side wall 325 and the second side wall 327 of the elastic connecting member 320 differ to correspond to the size of the step in the substrate seating surface 210.

[0045] The support member 310 includes a support base 312, a protruding seating portion 314 that protrudes from one surface of the support base 312 and is configured on which the elastic connecting member 320 is seated, and a fixing member 316 formed so as to fix the elastic connecting member 320 on the protruding seating portion 314.

[0046] Referring again to Figures 2a and 4, the plate-shaped base 324 of the elastic connecting member 320 is supported on the protruding seat portion 314, thereby forming a deformation gap 222 between the plate-shaped base 324 of the elastic connecting member 320 and the support base 312 of the support member 310.

[0047] In other words, in one embodiment of the present invention, the connector 300 includes a deformation gap 222 formed between the support base 312 and the elastic connecting member 320 such that when the first printed circuit board 10 and / or the second printed circuit board 12 are seated on the board seating surface 210, the lower surfaces of the printed circuit boards 10 and 12 press against the first contact portion 326 and the second contact portion 328, respectively, causing the elastic connecting member 320 to be elastically deformable (see Figure 2b).

[0048] Furthermore, in one embodiment of the present invention, the fixing member 316 includes a fixing member 316 formed on the protruding seating portion 314. The elastic connecting member 320 includes a through hole into which the fixing member 316 is inserted.

[0049] Figure 5 shows an example of a connector formed integrally through an insert injection molding method according to one embodiment of the present disclosure.

[0050] Referring to Figure 5, the connector 300 according to this disclosure is manufactured by an insert injection molding method. That is, the elastic connecting member 320 and the support member 310 are integrally formed through insert injection molding. However, the present invention is not limited thereto, and the elastic connecting member 320 and the support member 310 are each manufactured separately and joined together through separate assembly processes.

[0051] In one illustrated embodiment of the present invention, the connector 300 is exemplified as having a structure and size for transmitting and receiving high-frequency signals. However, the present invention is not limited thereto. The connector 300 can be modified and used as having a structure of size for transmitting other signals other than high-frequency signals, such as power or analog or digital low-frequency signals.

[0052] Figure 6a is a cross-sectional view of a part of a communication device according to another embodiment of the present disclosure, illustrating a case where a printed circuit board connected to a connector is not located at the same height as a printed circuit board.

[0053] Figure 6b is a cross-sectional view of a part of a communication device according to another embodiment of the present disclosure, illustrating a case where a printed circuit board of the same height is arranged on a printed circuit board connected to a connector.

[0054] Figure 7 is a perspective view relating to a part of a communication device according to another embodiment of the present disclosure.

[0055] Figure 8 is a perspective view showing only the connector of a communication device according to another embodiment of this disclosure.

[0056] A communication device according to another embodiment of the present disclosure will be described with reference to Figures 6 to 8. While the description of parts that overlap with one embodiment of the present disclosure will be omitted, it should be made clear that the features of one embodiment of the present disclosure can be applied to the other embodiment in a similar or analogous manner to the extent not included in the other embodiment of the present disclosure.

[0057] In other embodiments of this disclosure, the first seating surface 212 and the second seating surface 214 are formed on a flat surface so as to have the same or similar heights, i.e., without any steps. The first printed circuit board 10 and the second printed circuit board 12 may have the same or similar thicknesses. As a result, the upper surface of the first printed circuit board 10 and the upper surface of the second printed circuit board 12 are arranged on the same plane or a plane equivalent thereto.

[0058] When the first printed circuit board 10 and the second printed circuit board 12 are formed with the same or similar thickness, the substrate seating surface 210 is formed in a flat shape without any steps. In this case, the lengths (or vertical heights) of the first side wall 325 and the second side wall 327 of the elastic connecting member 320 are the same or similar.

[0059] Figure 9 is a perspective view of a part of the device configured to simulate the connector performance of the communication device relating to this disclosure.

[0060] Figure 10 is a perspective cross-sectional view of Figure 9.

[0061] Figure 11 shows the simulation results for the device configurations shown in Figures 9 and 10.

[0062] Figure 10 illustrates a communication device according to one embodiment of the present disclosure, in which the printed circuit boards 10 and 12 have different thicknesses and the side walls 325 and 327 have different heights. However, it should be made clear that the effects of the present invention described below do not occur only when following one embodiment of the present disclosure, but can also occur in other embodiments of the present disclosure, in which the printed circuit boards 10 and 12 have the same or similar thicknesses and the side walls 325 and 327 have the same or similar heights.

[0063] Referring to Figures 9 to 11, a virtual digital board and a virtual amplifier board structure were used to simulate the connector performance of the communication device according to the present invention.

[0064] The virtual digital board (second printed circuit board 12) and the virtual amplifier board (first printed circuit board 10) each include a first electrode 54 and a second electrode 52 that contact the first contact portion 326 and the second contact portion 328 of the elastic connecting member 320, respectively, and form an electrical connection.

[0065] For the simulation, it was shown that multiple via holes 56 surround the first electrode 54 and the second electrode 52, and that each of the first electrode 54 and the second electrode 52 is provided with a port 58 for signal transmission.

[0066] As shown in the simulation results in Figure 11, the reflection loss of connector 300 was found to be 20 dB for this configuration. Furthermore, it was found that the isolation value is 50 dB when the spacing of the connector 300 structure is 10 mm (1 cm) and the frequency of the high-frequency signal is 2.16 GHz. In addition, it was found that the insertion loss is a maximum of 0.1 dB.

[0067] It is possible to confirm that the degree of isolation differs depending on the spacing of the connector structures, and by referring to the simulation results, the spacing of the connector structures can be determined and optimized according to the connector structure and the type of high-frequency signal.

[0068] According to the present invention, the first printed circuit board 10 and the second printed circuit board 12, which are a type of heat source, have their thermal management, particularly their heat dissipation performance through direct heat conduction, which is an important factor in determining the overall performance of the device.

[0069] Therefore, in one embodiment of the present invention, the first printed circuit board 10 and the second printed circuit board 12 are arranged to be in direct contact with the mechanism casing 20, for example, the external housing.

[0070] However, the region where the first printed circuit board 10 and the second printed circuit board 12 are spaced apart and side by side has relatively little effect on the heat dissipation performance of the printed circuit boards due to direct conduction.

[0071] The present invention forms a connecting structure for connecting two printed circuit boards in a spaced-out area between them. Since the mechanism casing 20, for example, the outer housing, is itself made of a metallic shielding material, the connector according to one embodiment of the present invention can maintain an effective shielding state from the outside within the connecting groove 220. That is, even without covering the connector with a separate RF shielding member, the connector of the communication device according to the present invention has a sufficient shielding effect (degree of isolation) as revealed in the simulation results above.

[0072] Furthermore, since the printed circuit board can have a structure in which as large an area as possible is in direct surface contact with the mechanism housing 20, a communication device is provided that has excellent heat dissipation performance while being compact in size.

[0074] Figure 12b is a cross-sectional view of a part of a communication device according to another embodiment of the present disclosure, illustrating the case in which a printed circuit board is arranged.

[0075] Figure 13 is a perspective view of a part of a communication device according to another embodiment of the present disclosure.

[0076] Figure 14 is an exploded perspective view of a connector according to another embodiment of the present disclosure.

[0077] Figure 15 is a cross-sectional view of a gasket according to another embodiment of the present disclosure.

[0078] Before describing a communication device according to another embodiment of this disclosure, we will omit the explanation of parts that overlap with the communication device according to an embodiment different from the one described above. However, we will clarify that the contents of the communication device according to an embodiment different from the one described above (for example, the support base, protruding seating portion, fixing member, plate-type base, first side wall, first contact portion, second side wall, second contact portion, etc.) can be applied to the communication device according to another embodiment of this disclosure in the same or similar manner, to the extent that they are not arranged.

[0079] Referring to Figures 12 to 15, another embodiment of the present disclosure of a communication device includes a connector 1400 and a gasket 1430.

[0080] The connector 1400 includes a support member 1410 and an elastic connecting member 1420.

[0081] The support member 1410 includes a support base 1412, a protruding seating portion 1414, a fixing member 1416, and a protruding insertion portion 1418.

[0082] The elastic connecting member 1420 includes a plate-shaped base 1424, a first side wall 1425, a first contact portion 1426, a second side wall 1427, and a second contact portion 1428.

[0083] The gasket 1430 includes a body 1432 and an insertion groove 1434.

[0084] A support member 1410 according to another embodiment of the present disclosure further includes a protruding insertion portion 1418 for coupling with a gasket 1430. The protruding insertion portion 1418 is formed on both sides of the protruding seat portion 1414. The protruding insertion portion 1418 is formed to protrude from the support base 1412. The support member 1410 and the gasket 1430 are coupled by inserting the protruding insertion portion 1418 into the insertion groove 1434 of the gasket 1430. An elastic connecting member 1420 is positioned between the support member 1410 and the gasket 1430. To ensure a secure coupling between the support member 1410 and the gasket 1430, the protruding insertion portion 1418 is formed in a shape corresponding to the shape of the insertion groove 1434 of the gasket 1430, and the height of the protruding insertion portion 1418 is the same as or similar to the height of the insertion groove 1434. The protruding insertion portion 1418 is formed to a height higher than the protruding seat portion 1414.

[0085] In the following description, the gasket 1430 will be described as a separate component from the connector 1400. However, it should be noted that the gasket 1430 and the connector 1400 do not necessarily have to be separate components, and the gasket 1430 may be understood as one component included in the connector 1400.

[0086] The gasket 1430 is positioned to cover at least a portion of the connector 1400 in order to improve the shielding effect of the connector 1400. The gasket 1430 is positioned to cover at least a portion of the elastic connecting member 1420 of the connector 1400. The gasket 1430 is positioned to cover at least a portion of the plate-shaped base 1424 of the elastic connecting member 1420. As shown in Figures 13 and 14, the gasket 1430 is positioned to intersect with the connector 1400. This improves the shielding effect of the connector 1400 while electrically connecting multiple printed circuit boards. The gasket 1430 is positioned perpendicular to the connector 1400.

[0087] The gasket 1430 is coupled to the connector 1400. The gasket 1430 is configured so that at least a portion of the connector 1400 and the protruding insertion portion 1418 of the support member 1410 can be inserted into it. The gasket 1430 includes a body portion 1332 and an insertion groove 1434. The protruding insertion portion 1418 of the support member 1410 is inserted into the insertion groove 1434. As described above, the insertion groove 1434 and the protruding insertion portion 1418 are formed in corresponding shapes to each other, so that the gasket 1430 and the connector 1400 can be firmly coupled. The height of the insertion groove 1434 may be the same as or similar to the height of the protruding insertion portion 1418.

[0088] Referring to Figure 15, the height h of the insertion groove 1434 is more than half the total height H of the gasket 1430. For example, if the total height H of the gasket 1430 is 1.2 mm, the height of the insertion groove 1434 is 0.7 mm. This allows for a strong bond between the gasket 1430 and the connector 1400 without increasing the package size, and also improves the shielding effect of the connector 1400.

[0089] The gasket 1430 is made of aluminum to improve the shielding effect of the connector 1400, but the material of the gasket 1430 is not limited to this, and various materials can be used to improve the shielding effect of the connector 1400.

[0090] Figure 16 shows simulation results for another embodiment of the present disclosure, including gasket 1430.

[0091] Referring to Figure 16, the reflection loss of the connector 1400 of the communication device, including the gasket 1430, is shown to be 21.7451 dB when the frequency of the high-frequency signal is 4 GHz. Furthermore, the isolation value for S(1,3) at a high-frequency signal frequency of 4 GHz is 124.0433 dB, confirming a significant improvement in shielding effect compared to the case without the gasket 1430 (see Figure 11). In addition, the insertion loss is found to be 0.1711 dB at a high-frequency signal frequency of 4 GHz.

[0092] Thus, the communication device including the gasket 1430 according to this disclosure has the effect of significantly increasing the shielding effect of the connector 1400 by arranging the gasket 1430 so as to cover at least a portion of the connector 1400.

[0093] Figure 17 is an exploded perspective view of a connector including a gasket without an insertion groove, according to another embodiment of the present disclosure.

[0094] Referring to Figure 17, the gasket 1430 according to another embodiment of this disclosure does not have the aforementioned insertion groove 1434, and both the upper and lower surfaces are formed flat. When the gasket 1430 does not have an insertion groove 1434, the gasket 1430 is seated on the support member 1410, for example, on a protruding seat portion 1414 (see Figure 14) or a protruding insertion portion 1418 (see Figure 14), and covers the connector 140. When the gasket 1430 is formed in a flat shape without including an insertion groove 1434, the shielding effect of the connector 1400 is improved while the structure is simple and manufacturing costs are reduced.

[0095] Figure 18 is an exploded perspective view of a connector including a gasket with an insertion groove, according to another embodiment of the present disclosure.

[0096] Referring to Figure 18, the gasket 1430 according to another embodiment of the present disclosure has an insertion groove 1434 formed therein, as described above. For example, the insertion groove 1434 is formed on the lower surface of the gasket 1430. As shown in Figure 18, one surface of the gasket 1430 (for example, the lower surface) is formed to have a step, and the insertion groove 1434 is formed on the surface formed to have the step. The connector 1400 and the gasket 1430 are joined by inserting a part of the support member 1410 (for example, a protruding insertion part 1418, see Figure 14) into the insertion groove 1434. When the gasket 1430 has an insertion groove 1434 and is used to join the connector 1400 and the gasket 1430, the reflection loss is improved as will be described later.

[0097] Figure 19 shows the simulation results for the connectors illustrated in Figures 17 and 18.

[0098] Referring to Figure 19, the reflection loss A of the connector 1400 covered with a flat gasket 1430 without the insertion groove 1434 described in relation to Figure 17 is 19.1064 dB when the frequency of the high-frequency signal is 4 GHz. The reflection loss B of the connector 1400 covered with a gasket 1430 formed with a step including the insertion groove 3 described in relation to Figure 18 is 26.7269 dB when the frequency of the high-frequency signal is 4 GHz. In other words, it can be seen that the reflection loss is improved when the insertion groove 1434 is formed in the gasket 1430 and the connector 1400 and gasket 1430 are connected using this groove. However, even when using the flat gasket 1430 shown in Figure 17, a relatively good reflection loss can be expected while improving the shielding effect of the connector 1400, and the structure is simple and manufacturing costs are reduced, so a gasket 1430 with an appropriate structure can be selected and applied as needed.

[0099] The above description is merely illustrative of the technical concept of this embodiment, and any person with ordinary skill in the art to which this embodiment belongs could make various modifications and variations without departing from the essential characteristics of this embodiment. Therefore, this embodiment is for illustrative purposes only, not to limit the technical concept of this embodiment, and the scope of the technical concept of this embodiment is not limited by such embodiment. The scope of protection of this embodiment should be interpreted by the claims, and all technical concepts within an equivalent scope should be interpreted as being included in the scope of rights of this embodiment.
