Description

Technical Field

[0001] The utility model relates to the field of radio frequency technology, in particular to a radio frequency connector and an integrated circuit board. Background Art

[0002] Radio frequency (RF) is short for radio frequency current, which is a type of high-frequency alternating electromagnetic wave. Alternating current that changes less than 1,000 times per second is called low-frequency current, while current that changes more than 10,000 times per second is called high-frequency current. RF is one such high-frequency current.

[0003] Current RF connectors typically include a shielding cover and external signal connection terminals disposed within the shielding cover. The shielding cover and the external signal connection terminals are integrally formed. When the external signal connection terminals are damaged and need to be replaced, the RF connector as a whole needs to be removed. However, the shielding cover is typically fixed to the circuit board by welding or using a threaded locking structure, resulting in cumbersome steps for removing the shielding cover and troublesome replacement of the external signal connection terminals.

[0032] In the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] In the description of this utility model, reference to the terms "one embodiment," "some optional implementations," or "some optional embodiments" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0034] Current RF connectors typically include a shielding cover and external signal connection terminals disposed within the shielding cover. The shielding cover and the external signal connection terminals are integrally formed. When the external signal connection terminals are damaged and need to be replaced, the RF connector as a whole needs to be removed. However, the shielding cover is typically fixed to the circuit board by welding or using a threaded locking structure, resulting in cumbersome steps for removing the shielding cover and troublesome replacement of the external signal connection terminals.

[0035] The utility model adopts a detachable RF connector, in which the main body is fixed on the circuit board, and the expansion head is detachable and matched with the main body. Since the damage caused during use is mainly concentrated on the expansion head, the main body does not need to be removed from the circuit board when replacing the expansion head, which is convenient for maintenance.

[0036] See also Figure 1 An embodiment of the present invention provides a radio frequency connector, including: a body 10 and an extension head 20.

[0037] Please also see Figure 1and Figure 2 The main body 10 is provided with a first signal connection terminal 11. The extension head 20 is detachably connected to the main body 10. The extension head 20 is provided with a second signal connection terminal 21 and a third signal connection terminal 22 that are electrically connected to each other. The second signal connection terminal 21 is electrically connected to the first signal connection terminal 11, so that the third signal connection terminal 22 is electrically connected to the first signal connection terminal 11 through the second signal connection terminal 21.

[0038] The RF connector body 10 can be mounted on an integrated circuit board, which can be a card or the like, without limitation. The integrated circuit board can be mounted on an electronic device, such as a television, a computer display, or other type of device. The first signal connection terminal 11 is signal-connected to the integrated circuit board, and a signal connection is established between the integrated circuit board and the RF signal receiving and processing module, enabling the RF signal receiving and processing module to receive external RF signals or output RF signals to the outside via the first signal connection terminal 11, the second signal connection terminal 21, and the third signal connection terminal 22.

[0039] In this embodiment, an integrated circuit board is used as a board, and an RF connector is provided on the board. Receiving an external RF signal through the RF connector on the board is described as an example, wherein the external RF signal source is detachably connected to the extension head 20 through the external RF connector, and the signal connection end on the external RF connector is electrically connected to the third signal connection end 22. The external RF signal passes through the signal connection end on the external RF connector, the third signal connection end 22, the second signal connection end 21 and the first signal connection end 11 in sequence, and is then received by the RF connector of the integrated circuit board. During use, when the external RF connector is connected to the extension head 20, friction will occur between the external signal connection end and the third signal connection end 22, causing the third signal connection end 22 to wear. In addition, due to accidents such as user accidental touch, the external RF connector is subjected to external force and deviates from its position, which can easily cause the third signal connection end 22 on the extension head 20 to be damaged by external force. Since the damage is mainly concentrated on the third signal connection end 22, and the extension head 20 is detachable and replaceable, it is convenient to quickly replace the third signal connection end 22. Although the main body 10 is fixed on the integrated circuit board and is not easy to replace, since the first signal connection end 11 is not easily damaged, the overall maintenance of the RF connector is relatively convenient.

[0040] The structures of the first signal connection end 11, the second signal connection end 21 and the third signal connection end 22 can be designed according to actual needs. For example, the first signal connection end 11 and the third signal connection end 22 both include two elastic clips arranged side by side. The second signal connection end 21 is columnar, and the second signal connection end 21 is inserted between the two elastic clips of the first signal connection end 11. The signal connection end on the external RF connector is inserted between the two elastic clips of the third signal connection end 22.

[0041] The third signal connection terminal 22 actually replaces the first signal connection terminal 11 to connect to an external signal connection terminal. In this embodiment, the signal connection terminal that the first signal connection terminal 11 can be adapted to connect to is the same as the signal connection terminal that the third signal connection terminal 22 can be adapted to connect to. Of course, depending on actual usage needs, the signal connection terminal that the first signal connection terminal 11 can be adapted to connect to and the signal connection terminal that the third signal connection terminal 22 can be adapted to connect to can also be different. To this end, different extension headers 20 can be prepared, and the third signal connection terminals 22 on different extension headers 20 have different structures, so that the third signal connection terminals 22 on different extension headers 20 can be adapted to connect to different signal connection terminals. Therefore, by replacing the extension header 20 connected to the main body 10, the first signal connection terminal 11 can be adapted to connect to different signal connection terminals.

[0042] The detachable connection method between the main body 10 and the expansion head 20 can be designed according to actual needs. For example, in some optional embodiments, the main body 10 is detachably connected to the expansion head 20 via a threaded structure or a snap-fit structure. Of course, the expansion head 20 can also be provided with a bayonet, and the main body 10 and the bayonet have an interference fit, thereby achieving detachable fit between the main body 10 and the expansion head 20.

[0043] See also Figure 3 In this embodiment, the main body 10 is provided with a connecting ring 12 surrounding the first signal connection terminal 11; when the main body 10 is detachably connected to the expansion head 20 via a threaded structure, the threaded structure includes a first threaded portion 13 provided on the connecting ring 12 and a second threaded portion 23 provided on the expansion head 20, and the first threaded portion 13 and the second threaded portion 23 are adapted to each other. In other optional embodiments, when the main body 10 is detachably connected to the expansion head 20 via a snap-fit structure, the snap-fit structure includes a plurality of snap members provided on the main body 10 and a plurality of snap grooves provided on the expansion head 20, and the snap members snap into engagement with the snap grooves accordingly. Of course, the structure of the threaded structure or snap-fit structure is not limited to this, and those skilled in the art may also select other suitable structures based on the teachings of the present invention.

[0044] Please also see Figure 1 、 Figure 4 and Figure 5 In some optional embodiments, the RF connector further includes a protective cover 30, and both the extension head 20 and the protective cover 30 can be detachably connected to the body 10. The protective cover 30 can be detachably connected to the body 10 using the same structure and method as the extension head 20. The protective cover 30 can also be detachably connected to the body 10 using other suitable connection methods. For example, the protective cover 30 can be provided with a slot, and the connecting ring 12 can be snapped into the slot to achieve detachable connection between the protective cover 30 and the body 10.

[0045] When the integrated circuit board needs to input or output a radio frequency signal, the extension head 20 is detachably connected to the body 10 .

[0046] When the integrated circuit board does not need to access or output radio frequency signals, the extension head 20 is removed from the main body 10, and the protective cover 30 is detachably connected to the main body 10. When the protective cover 30 is detachably connected to the main body 10, the protective cover 30 shields the first signal connection terminal 11, thereby protecting the first signal connection terminal 11. Moreover, since the first signal connection terminal 11 on the main body 10 usually needs to be exposed on the outside of the electronic device, it is convenient for the user to observe and remove the extension head 20. However, since the extension head 20 protrudes from the main body 10, the extension head 20 actually protrudes from the electronic device, which affects the appearance of the electronic device. Removing the extension head 20 when it is not needed can make the electronic device more beautiful, and the first signal connection terminal 11 is also shielded to prevent the first signal connection terminal 11 from being exposed, which also helps to improve the appearance.

[0047] See also Figure 3 The specific structure of the main body 10 can be designed according to actual needs. For example, in some optional embodiments, the main body 10 includes a shielding cover 14 and a first signal connector 15 disposed within the shielding cover 14. The first signal connector 15 is formed with a first signal connection terminal 11. A portion of the first signal connection terminal 11 is located within the shielding cover, and another portion of the first signal connection terminal 11 is located outside the shielding cover 14. The shielding cover 14 can prevent external electromagnetic fields from interfering with the radio frequency signal transmission of the first signal connector 15, thereby improving signal transmission stability.

[0048] To prevent the shielding cover 14 from contacting the first signal connector 15 and thus affecting RF signal transmission, in some optional embodiments, the body 10 further includes a first isolator 16. An opening 17 is provided on the side of the shielding cover 14. The first isolator 16 is disposed within the opening 17 to close the opening 17. The first isolator 16 is provided with a first through-hole 161. The first signal connection terminal 11 is partially disposed in the first through-hole 161 and is partially located outside the shielding cover 14. The first isolator 16 maintains an appropriate distance between the first signal connection terminal 11 and the shielding cover 14. In this embodiment, the opening 17 on the side of the body 10 is formed on the connecting ring 12, and the first isolator 16 is connected to the connecting ring 12.

[0049] See also Figure 3The specific structure of the extension head 20 can be designed according to actual needs. For example, in some optional embodiments, the extension head 20 includes a housing 24 and a second signal connector 25. The housing 24 is provided with a mounting channel 26. The second signal connector 25 is disposed within the mounting channel 26. The second signal connector 21 and the third signal connector 22 are respectively located at opposite ends of the second signal connector 25. The second signal connector 21 and the third signal connector 22 are respectively located at opposite ends of the mounting channel 26. The housing 24 provides protection for the second signal connector 25. In this embodiment, a second threaded portion 23 is provided on the housing 24. When the housing 24 is connected to the connecting ring 12 on the body 10, the second signal connector 21 extends into the opening 17 on the side of the body 10 to connect with the first signal connector 11. Alternatively, the first signal connector 11 extends into the mounting channel 26 to connect with the second signal connector 21.

[0050] In some optional embodiments, the housing 24 is a conductive housing 24 . When the external RF connector is connected to the conductive housing 24 , the conductive housing 24 is connected to the external signal reference ground, thereby improving the transmission of the RF signal in the second signal connector 25 .

[0051] The extension head 20 also includes a second isolating member 27, which is disposed in the mounting channel 26. A second through hole 271 is provided on the second isolating member 27, and a portion of the second signal connector 25 is passed through the second through hole 271. The second isolating member 27 can prevent the conductive housing 24 from contacting the second signal connector 25 and affecting the transmission of the RF signal.

[0052] The first isolating member 16 and the second isolating member 27 may be made of plastic or other non-conductive materials to achieve an isolation effect.

[0053] The above-mentioned radio frequency connector can be applied to an integrated circuit board, which includes: a circuit board body and a radio frequency connector as described above, wherein the body (10) is arranged on the circuit board body. The integrated circuit board can be a circuit board applied to a specific field, such as a card.
