Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the radio frequency transmission device and the electronic device provided by the present invention in detail with reference to the accompanying drawings.

First embodiment

Referring to fig. 1 and fig. 2 together, the rf transmission device provided in the present embodiment can be applied to any product requiring an rf transmission cable, such as a mobile phone, a tablet computer, etc., and the product can be a 2G/3G/4G/5G terminal, especially a 5G terminal.

The radio frequency transmission device comprises a mainboard module 1 and a circuit board module 2, wherein a circuit board 21 of the circuit board module 2 is used for realizing the transmission of radio frequency signals, and a signal source can be an antenna, a radio frequency module, a mainboard and other devices, circuits or modules and the like. Optionally, the Circuit board 11 is a Flexible Printed Circuit (FPC) which is made of, for example, an LCP (Liquid Crystal Polymer) dielectric material, and the dielectric material is a material with a low dielectric constant and low loss, and can be applied to a millimeter wave Circuit, so as to meet the requirement of a 5G terminal. The main board 11 of the main board module 1 is used for receiving, transmitting and processing radio frequency signals.

The main board 11 of the main board module 1 and the circuit board 21 of the circuit board module 2 are detachably connected together by the board connector 3, and when connected, the first rf signal transmission line 12 of the main board module 1 is electrically conducted with the second rf signal transmission line 22 of the circuit board module 2. In the present embodiment, the board connector 3 includes a first connector 31 and a second connector 32 capable of being plugged with each other to electrically conduct the second radio frequency signal transmission line 22 and the first radio frequency signal transmission line 12 when plugged. Specifically, the first connector 31 and the second connector 32 are a pair of male and female connectors, which are connected in a pluggable manner, and when connected, the two contacts of the first connector 31 and the second connector 32 are electrically contacted, so that the second radio frequency signal transmission line 22 and the first radio frequency signal transmission line 12 are electrically conducted.

Of course, in practical applications, the motherboard module 1 and the circuit board module 2 may also adopt any other connector to realize detachable or non-detachable connection and transmission of radio frequency signals.

The rf transmission device provided in this embodiment further includes a test socket assembly 4, where the test socket assembly 4 is disposed on the circuit board 21 of the circuit board module 2, and is used for being plugged into the connector 5 of the test instrument, and when the connector 5 is plugged into the first rf signal transmission line 12 of the motherboard module 1, the second rf signal transmission line 22 of the circuit board module 2 is disconnected from the first rf signal transmission line 12, at this time, the signal test can be directly performed on the motherboard module 1, and the circuit board module 2 does not need to be detached, that is, the signal test is performed under the condition that the circuit board 21 and the motherboard 11 are kept connected. Meanwhile, since the second rf signal transmission line 22 is disconnected from the first rf signal transmission line 12, it can be ensured that the circuit board module 2 does not affect the test.

In addition, when the connector 5 of the test instrument is pulled out from the test socket assembly 4, the connector 5 is disconnected from the first radio frequency signal transmission line 12 of the motherboard module 1, and at this time, the second radio frequency signal transmission line 22 and the first radio frequency signal transmission line 12 can be connected, so that when the motherboard module 1 and the circuit board module 2 are in a non-test state, a normal on state of radio frequency signals between the motherboard module 1 and the circuit board module 2 is recovered, and radio frequency signals can be transmitted mutually.

The specific structure of the test socket assembly 4 described above will be described in detail below. Specifically, the test socket assembly 4 includes a test socket 41 and a reset switch 42, wherein the test socket 41 is disposed on the circuit board 11 of the circuit board module 1 for plugging with the connector 5 of the test instrument. Optionally, the test socket 41 and the connector 5 are a socket and a plug of a coaxial radio frequency test connector (Stone bulk phase, hereinafter abbreviated as SMA), respectively, and the SMA is a universal connector for 5G radio frequency transmission. In practical application, the socket and the plug of the SMA are universal, so that a special test plug is not required to be additionally equipped, and the socket and the plug of the SMA are low in price, so that the equipment and use cost can be reduced.

In the present embodiment, as shown in fig. 2, the first connector 31 and the test socket 41 of the board connector 3 are both disposed on the circuit board 21 of the circuit board module 2, and the first connector 31 and the test socket 41 adopt a split structure, so that the position of the test socket 41 on the circuit board 21 can be flexibly designed, for example, the first connector 31 and the test socket 41 are respectively disposed on two surfaces of the circuit board 21 that are away from each other, so as to facilitate the insertion of the connector 5 of the test instrument under the condition that the circuit board 21 and the motherboard 11 are kept connected. Meanwhile, the shape and size of the test socket 41 can be freely designed, thereby providing convenience for design.

The reset switch 42 is disposed in the test socket 41, and is configured to, when the test socket 41 is plugged into the connector 5, as shown in fig. 3A, connect the trigger 51 (i.e., the test probe) in the connector 5 with the first rf signal transmission line 12 of the motherboard module 1, so as to enable an rf signal test on the motherboard 11; at the same time, the second rf signal transmission line 22 and the first rf signal transmission line 12 of the circuit board module 2 are disconnected, thereby ensuring that the circuit board module 2 does not affect the test. When the test socket 41 is separated from the connector 5, as shown in fig. 3B, the reset switch 42 turns on the first rf signal transmission line 12 and the second rf signal transmission line 22, so that the normal on-state of the rf signal between the motherboard module 1 and the circuit board module 2 can be recovered when the test socket is in the non-test state, that is, the rf signal can be transmitted to each other.

From the above, under the condition that the circuit board module 2 is not detached (i.e., the circuit board 21 is connected to the main board 11), the radio frequency signal test can be performed on the main board 1 by directly inserting the connector 5 into the test socket 41, so that the condition that the main board is damaged or internal damage is generated due to the insertion and extraction of the connector of the board connector 3 does not exist, and a special test probe matched with the connector of the board connector 3 does not need to be provided, thereby reducing the cost.

When the test socket 41 is plugged into the connector 5, the trigger 51 triggers the reset switch 42 to connect the trigger 51 to the first rf signal transmission line 12 and disconnect the second rf signal transmission line 22 from the first rf signal transmission line 12, and fig. 3A shows a state where the reset switch 42 is triggered by the trigger 51. When the test socket 41 is separated from the contact 5, the reset switch 42 is reset to re-turn on the first rf signal transmission line 12 and the second rf signal transmission line 22, and fig. 3B shows a state of the reset switch 42 in a reset state in which the contact 5 is separated from the test socket 41, that is, the triggering piece 51 of the contact 5 is disconnected from the first rf signal transmission line 12.

In the present embodiment, the second rf signal transmission line 22 includes a first portion 221 and a second portion 222, i.e., two line segments of the second rf signal transmission line 22 located at both sides of the reset switch 42, wherein the first portion 221 is electrically connected to the first rf signal transmission line 12 through the board connector 3. When the main board 1 needs to be subjected to the radio frequency signal test, the first portion 221 and the first radio frequency signal transmission line 12 can be kept connected without being disconnected.

As shown in fig. 3A and 3B, the reset switch 42 includes a first elastic member 421 and a second elastic member 422, wherein the first elastic member 421 is electrically connected to the first portion 221, and when the test socket 41 is plugged into the connector 5, the first elastic member 421 moves to a position disconnected from the second elastic member 422 under the trigger of the trigger 51, and at this time, the second portion 222 is disconnected from the first rf signal transmission line 12, so as to ensure that the circuit board module 2 does not affect the test. When the test socket 41 is separated from the connector 5, the first elastic member 421 is restored to the position electrically contacting with the second elastic member 422 by its own elastic force, and at this time, the second portion 222 is electrically conducted with the first rf signal transmission line 12, so that the normal conduction state of the rf signal between the main board module 1 and the circuit board module 2 can be restored, that is, the rf signal can be mutually transmitted.

Alternatively, the first elastic member 421 and the second elastic member 422 are both spring pieces. Of course, in practical applications, the first elastic member 421 and the second elastic member 422 may also adopt any other elastic structures.

By adopting the reset switch 42, the first radio frequency signal transmission line 12 and the second radio frequency signal transmission line 22 can be automatically connected when the test socket 41 is separated from the connector 5, thereby improving the convenience of operation. It should be noted that, in the present embodiment, only one reset switch is shown, but the present invention is not limited to this, and in practical applications, any other reset switch may be adopted.

However, the present embodiment differs from the first embodiment described above in that: the reset switch 42 is replaced with a selection switch 42'.

Specifically, referring to fig. 4 and 5, the selection switch 42 'can be selectively moved to a first position shown in fig. 4 or a second position shown in fig. 5, wherein the selection switch 42' is in the first position to turn on the first portion 221 and the second portion 222 of the second rf signal transmission line 22; in the second position, the first part 221 and the second part 222 are disconnected and the first part 221 and the trigger piece 51 are electrically conducted when the test socket 41 is plugged with the connector 5.

In practice, the switch 42' can be controlled to switch between the first position and the second position manually or automatically. The automatic control method is, for example, electric or pneumatic.

However, the present embodiment differs from the first embodiment described above in that: the first connector 31 'and the test socket 41' are of an integral structure.

By adopting the integrated structure of the first connector 31 'and the test socket 41', the structure of the device can be simplified, and convenience is brought to processing and installation.

Other structures of the radio frequency transmission apparatus provided in this embodiment are the same as those of the first embodiment, and are not described herein again.
