Description

Technical Field

[0001] The embodiments of the present invention relate to the field of household appliance accessories, and in particular to the field of radio frequency connectors. Background Art

[0002] A digital video conversion box (Set Top Box), also known as a set-top box or set-top box, is a device that connects a TV set to an external signal source. It can convert compressed digital signals into TV content and display it on the TV set. The signal can come from cable, satellite antenna, broadband network and terrestrial broadcasting. In addition to the images and sounds that analog TV can provide, the set-top box can also receive digital content, including electronic program guides, Internet pages, etc. It enables users to watch digital TV programs on existing TV sets and conduct interactive digital entertainment, education and commercial activities through the Internet.

[0003] The inventors have discovered that the radio frequency connector in the existing set-top box structure does not have the function of fast signal switching when working, resulting in a poor user experience. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a radio frequency connector, so that when the radio frequency connector is working, the function of rapid signal switching can be realized, thereby improving the user experience.

[0005] To solve the above technical problems, an embodiment of the present invention provides a radio frequency connector, including: a hollow outer conductor, an elastic member, a first insulator, a second insulator, a third insulator, a first inner conductor, a second inner conductor, a third inner conductor and a fourth inner conductor; the first inner conductor, the second inner conductor, the third inner conductor and the fourth inner conductor are all arranged on the inner side of the outer conductor, wherein the third inner conductor is used to connect to an external device; the first inner conductor and the second inner conductor are connected and conducted through the elastic member; the first insulator is used to prevent the first inner conductor from contacting with other conductors; the second insulator is used to prevent the third inner conductor from contacting with other conductors; the third insulator is used to prevent the fourth inner conductor from contacting with other conductors; when the third inner conductor is not connected to an external device, the elastic member is in a relaxed state, the second inner conductor is conducted with the fourth inner conductor, and the first inner conductor and the third inner conductor are in a non-conducting state; when the third inner conductor is connected to an external device, the elastic member is in a compressed state, the third inner conductor is conducted with the first inner conductor, and the second inner conductor and the fourth inner conductor are in a non-conducting state.

[0006] Compared with the prior art, the radio frequency connector of the embodiment of the present invention includes: a hollow outer conductor, an elastic member, a first insulator, a second insulator, a third insulator, a first inner conductor, a second inner conductor, a third inner conductor and a fourth inner conductor. The third inner conductor is used to connect to an external device, and the first inner conductor and the second inner conductor are connected and conducted through the elastic member. When the third inner conductor is not connected to the external device, the elastic member is in a relaxed state, the second inner conductor and the fourth inner conductor are conducted, and the first inner conductor and the third inner conductor are in a non-conducting state. When the third inner conductor is connected to the external device, the elastic member is in a compressed state, the third inner conductor and the first inner conductor are conducted, and the second inner conductor and the fourth inner conductor are in a non-conducting state. In this way, when the external device and the radio frequency connector are in a connected state or a non-connected state, the conduction state between the inner conductors can be quickly switched, thereby realizing rapid switching of signals, and thus the radio frequency connector can greatly improve the user experience.

[0007] In addition, the elastic member is sleeved on the first inner conductor and is connected to the second inner conductor; the second inner conductor has a through hole, and when the third inner conductor is connected to an external device, the elastic member is in a compressed state, and the third inner conductor passes through the second inner conductor and the elastic member and is connected to the first inner conductor. The structure is simple, and the elastic member cannot be easily separated from the first inner conductor. When the third inner conductor is disconnected from the external device, the elastic member can rely on elastic force to quickly push the second inner conductor away, so that the second inner conductor is connected to the fourth inner conductor, and the signal is quickly switched.

[0008] In addition, the outer conductor has a first accommodating groove and a second accommodating groove for accommodating the second insulator and the third insulator respectively; the first accommodating groove and the second accommodating groove are mutually connected, the second accommodating groove is used to fix the third insulator, and the first accommodating groove is used to allow the second insulator to slide along the axis direction of the outer conductor. This structure allows the second insulator and the third insulator to be arranged in the outer conductor and realize the corresponding functions.

[0009] In addition, the third insulator has a receiving position for receiving and fixing the first insulator, so that the first insulator can be fixed on the third insulator.

[0010] In addition, the elastic member and the second inner conductor are both arranged in the third insulator, which can effectively save assembly space and make the structure of the RF connector more compact.

[0011] In addition, the third inner conductor includes: a first conductor segment and a second conductor segment; the first conductor segment and the second conductor segment are connected to each other; the second conductor segment is used to connect to an external device; the first conductor segment is used to conduct with the first inner conductor when the second conductor segment is connected to an external device. In this way, the structure of the third inner conductor can be connected to an external device and can also be conducted with the first inner conductor, thereby realizing the function of rapid signal switching.

[0012] In addition, the RF connector also includes a fifth insulator and a fifth inner conductor; the fifth insulator is used to prevent the fifth inner conductor from contacting other conductors; when the third inner conductor is not connected to an external device, the elastic member is in a relaxed state, the second inner conductor is respectively connected to the fourth inner conductor and the fifth inner conductor, and the first inner conductor is in a non-conductive state with the third inner conductor; when the third inner conductor is connected to an external device, the elastic member is in a compressed state, the third inner conductor is connected to the first inner conductor, and the second inner conductor is in a non-conductive state with the fourth inner conductor and the fifth inner conductor. This is equivalent to adding a loop to the RF connector on the original basis to optimize the function of the RF connector.

[0013] In addition, the second inner conductor is connected and fixed to the second insulator. After the second inner conductor is connected and fixed to the second insulator, it can be ensured that the third inner conductor cannot contact the second inner conductor.

[0014] In addition, the second inner conductor has a socket for inserting the second insulator. After the second insulator is inserted into the socket of the second inner conductor, it is fixed to the second inner conductor to ensure the stability of the connection between the second inner conductor and the second insulator.

[0015] In addition, the RF connector further comprises a hollow fourth insulator, which is used to support the first insulator on the outer conductor and to allow an external device to connect to the third inner conductor, thereby ensuring that the conductor of the external device can be insulated.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0022] A first embodiment of the present invention relates to a radio frequency connector, such as Figure 1 , 2 As shown, it includes: a hollow outer conductor 10, an elastic member 3, a first insulator 1, a second insulator 6, a third insulator 12, a first inner conductor 2, a second inner conductor 4, a third inner conductor 7 and a fourth inner conductor 5. The first inner conductor 2, the second inner conductor 4, the third inner conductor 7 and the fourth inner conductor 5 are all arranged on the inner side of the outer conductor 10. Among them, the third inner conductor 7 is used to connect with an external device, and the first inner conductor 2 and the second inner conductor 4 are connected and conducted through the elastic member 3. The first insulator 1 is used to prevent the first inner conductor 2 from contacting with other conductors; the second insulator 6 is used to prevent the third inner conductor 7 from contacting with other conductors; and the third insulator 12 is used to prevent the fourth inner conductor 5 from contacting with other conductors. When the third inner conductor 7 is not connected to the external device 11, the elastic member 3 is in a relaxed state, the second inner conductor 4 is in conduction with the fourth inner conductor 5, and the first inner conductor 2 and the third inner conductor 7 are in a non-conducting state. When the third inner conductor 7 is connected to the external device 11 , the elastic member 3 is in a compressed state, the third inner conductor 7 is conductively connected to the first inner conductor 2 , and the second inner conductor 4 and the fourth inner conductor 5 are in a non-conductive state.

[0023] Specifically, the outer conductor 10 has a first receiving groove and a second receiving groove for receiving the second insulator 6 and the third insulator 12 respectively. The first receiving groove and the second receiving groove are interconnected, the second receiving groove is used to fix the third insulator 12, and the first receiving groove is used for the second insulator 6 to slide along the axial direction of the outer conductor 10. This structure can make the second insulator 6 and the third insulator 12 both arranged in the outer conductor 10 and realize the corresponding functions. In addition, the third inner conductor 7 includes: a first conductor segment 13 and a second conductor segment 8; the first conductor segment 13 and the second conductor segment 8 are interconnected; the second conductor segment 8 is used to connect to the external device 11; the first conductor segment 13 is used to conduct with the first inner conductor 2 when the second conductor segment 8 is connected to the external device 11, so that the structure of the third inner conductor 7 can be connected to the external device 11 and can also be conducted with the first inner conductor 2, so that the function of fast signal switching can be realized.

[0024] It should be noted that, in this embodiment, the elastic member 3 is sleeved on the first inner conductor 2 and is connected to the second inner conductor 4; the second inner conductor 4 has a through hole, and the elastic member 3 is a spring. When the third inner conductor 7 is connected to the external device 11, the elastic member 3 is in a compressed state, and the third inner conductor 7 passes through the second inner conductor 4 and the elastic member 3 and is connected to the first inner conductor 2. The structure is simple, and the elastic member 3 cannot be easily separated from the first inner conductor 2. When the third inner conductor 7 is disconnected from the external device 11, the elastic member 3 can rely on the elastic force to quickly push the second inner conductor 4 away, so that the second inner conductor 4 is connected to the fourth inner conductor 5, and the signal is quickly switched.

[0025] It is worth mentioning that the third insulator 12 has a receiving position for receiving and fixing the first insulator 1, so that the first insulator 1 can be fixed on the third insulator 12. In addition, the elastic member 3 and the second inner conductor 4 are both arranged in the third insulator 12, which can effectively save assembly space and make the structure of the RF connector more compact.

[0026] In this embodiment, the second inner conductor 4 is connected and fixed to the second insulator 6. After the second inner conductor 4 is connected and fixed to the second insulator 6, it can be ensured that the third inner conductor 7 cannot contact the second inner conductor 4. Specifically, the second inner conductor 4 has a socket for the second insulator 6 to be inserted into. The second insulator 6 is inserted into the socket of the second inner conductor 4 and fixed to the second inner conductor 4, thereby ensuring the stability of the connection between the second inner conductor 4 and the second insulator 6.

[0027] In addition, the RF connector may also include a hollow fourth insulator 9, which is also disposed in the first accommodating groove. The fourth insulator 9 is used to support the first insulator 1 on the outer conductor 10 and provide the external device 11 with a connection to the third inner conductor 7, thereby ensuring that the conductor of the external device 11 can be insulated.

[0028] Compared with the prior art, the embodiment of the present invention comprises: a hollow outer conductor 10, an elastic member 3, a first insulator 1, a second insulator 6, a third insulator 12, a first inner conductor 2, a second inner conductor 4, a third inner conductor 7 and a fourth inner conductor 5. The third inner conductor 7 is used to connect to the external device 11, and the first inner conductor 2 and the second inner conductor 4 are connected and conducted through the elastic member 3. When the third inner conductor 7 is not connected to the external device 11, the elastic member 3 is in a relaxed state, the second inner conductor 4 and the fourth inner conductor 5 are conducted, and the first inner conductor 2 and the third inner conductor 7 are in a non-conducting state. When the third inner conductor 7 is connected to the external device 11, the elastic member 3 is in a compressed state, the third inner conductor 7 and the first inner conductor 2 are conducted, and the second inner conductor 4 and the fourth inner conductor 5 are in a non-conducting state. In this way, when the external device 11 and the RF connector are in a connected state or a non-connected state, the conduction state between the inner conductors can be quickly switched, thereby realizing rapid switching of signals, and thus the RF connector can greatly improve the user experience.

[0029] The second embodiment of the present invention relates to a radio frequency connector. The second embodiment further improves the radio frequency connector of the first embodiment. The main improvement is that: in the second embodiment, Figure 3 , 4 As shown, the RF connector also includes a fifth insulator 14 and a fifth inner conductor 15. The fifth insulator 14 is used to prevent the fifth inner conductor 15 from contacting other conductors. When the third inner conductor 7 is not connected to the external device 11, the elastic member 3 is in a relaxed state, the second inner conductor 4 is respectively connected to the fourth inner conductor 5 and the fifth inner conductor 15, and the first inner conductor 2 and the third inner conductor 7 are in a non-conductive state; when the third inner conductor 7 is connected to the external device 11, the elastic member 3 is in a compressed state, the third inner conductor 7 is connected to the first inner conductor 2, and the second inner conductor 4 and the fourth inner conductor 5 and the fifth inner conductor 15 are all in a non-conductive state. It is equivalent to adding a loop of the RF connector on the original basis to optimize the function of the RF connector.

[0030] Similarly, the third inner conductor 7 of the RF connector is used to connect to the external device 11, and the first inner conductor 2 and the second inner conductor 4 are connected and conducted through the elastic member 3. When the third inner conductor 7 is not connected to the external device 11, the elastic member 3 is in a relaxed state, the second inner conductor 4 is respectively conducted with the fourth inner conductor 5 and the fifth inner conductor 15, and the first inner conductor 2 and the third inner conductor 7 are in a non-conducting state; when the third inner conductor 7 is connected to the external device 11, the elastic member 3 is in a compressed state, the third inner conductor 7 is conducted with the first inner conductor 2, and the second inner conductor 4 and the fourth inner conductor 5 and the fifth inner conductor 15 are all in a non-conducting state. In this way, when the external device 11 and the RF connector are in a connected state or a disconnected state, the conduction state between the inner conductors can also be quickly switched, thereby realizing a fast switching of signals, and thus the RF connector can greatly improve the user experience.

[0031] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
