In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Referring to fig. 1 to 10, the wire control structure of the present embodiment includes a first metal housing 1, a second housing 2, a flexible circuit board 4 and a circuit board 6. Wherein the first metal casing 1 serves as an antenna radiator. The first and second metal cases 1 and 2 are respectively formed with first and second accommodation chambers, and further include an insulating frame 3 between the first and second metal cases 1 and 2, the insulating frame 3 separating the first and second metal cases 1 and 2.
Specifically, the arrangement of the insulating frame 3 realizes an insulating function between the first metal housing 1 and the second housing 2, which cuts off the first metal housing 1 on the left side and the second housing 2 on the right side as a metal antenna. Therefore, the second casing 2 does not interfere with the signal transmission of the first metal casing 1, so that the first metal casing 1 is convenient for receiving external radio frequency signals or transmitting radio frequency signals to the outside.
Meanwhile, the arrangement of the insulating frame 3 can also play a role in fixing the first metal shell 1 and the second shell 2. That is, the first metal housing 1 and the second housing 2 are simultaneously sleeved on the insulating frame 3, thereby forming the overall appearance of the wire control structure.
Further, the circuit board 6 is disposed in the second accommodation chamber, and the first metal case 1 and the circuit board 6 are electrically connected through the flexible wiring board 4. That is, the first metal case 1 is in conduction with one end of the flexible wiring board 4, and the other end of the flexible wiring board 4 passes through the insulating frame 3 and is in conduction with the circuit board 6 in the second case 2. Thereby, conduction is completed between the first metal shell 1 and the circuit board 6, and finally, signal transmission between the first metal shell 1 and the circuit board 6 is realized.
Among these, flexible wiring boards are also called "flexible boards", and are printed circuits made of flexible insulating substrates. The flexible circuit provides excellent electrical performance, meets the design requirements of smaller and higher density mounting, and also helps reduce assembly processes and enhance reliability. The flexible circuit board can be arranged randomly according to the space layout requirement and can move and stretch randomly in a three-dimensional space, so that the integration of component assembly and wire connection is achieved. The flexible circuit board can greatly reduce the volume and weight of the electronic product, and is suitable for the requirements of the electronic product on high density, miniaturization and high reliability.
In summary, the flexible circuit board 4 is directly connected to the first metal housing 1 and the circuit board 6, so that the space layout of the wire control structure is reduced, the space is saved, and the high density, miniaturization and high integration of the wire control structure are realized.
Referring to fig. 4, the flexible circuit board 4 has a flat sheet structure.
In the prior art, a coaxial cable with a traditional circular section is generally adopted to communicate the first metal shell with the circuit board. Also, there is a need to leave an assembly space for the coaxial cable in the wire control structure, which occupies a large layout space in the wire control structure.
In this embodiment, the flexible wiring board 4 of a flat sheet-like structure may be provided with a gap or interval between the second housing 2 and the circuit board 6 without additionally reserving an assembling space for the flexible wiring board 4. The flexible wiring board 4 occupies a small space in the wiring structure as compared with the coaxial cable. And, communication between the first metal housing 1 and the circuit board 6 can be achieved in a limited space.
Further, the flat sheet-like structure may also facilitate connection and assembly. Meanwhile, the flexible circuit board 4 has the function of an integrated matching circuit, so that the later debugging of the antenna is facilitated, which is not possessed by a coaxial cable with a circular section.
Referring to fig. 3 to 6, a spring body 5 is disposed in the first accommodating chamber.
Specifically, one side of the spring body 5 is electrically connected to the flexible circuit board 4, and the opposite side of the spring body 5 is electrically connected to the first metal housing 1. Therefore, the elastic piece body 5 can be used for communicating the metal antenna (the first metal shell 1) to the flexible circuit board 4, and then is communicated to the upper surface of the circuit board 6 through the flexible circuit board 4, so that the conduction between the first metal shell 1 and the circuit board 6 is finally realized, and the transmission of radio frequency signals is realized.
Further, the elastic sheet body 5 is arranged to be communicated with the first metal shell 1 and the flexible circuit board 4, and the elastic sheet body 5 can play a role in flexible connection. The connection force and the external force between the first metal case 1 and the flexible wiring board 4 are buffered.
Compared with the rigid connection, the flexible connection can buffer the external force when the first metal shell 1 receives the external force, and does not directly transmit the external force to the flexible circuit board 4 (the rigid connection directly transmits the external force to the flexible circuit board 4), thereby playing a role in protecting the flexible circuit board 4.
Referring to fig. 5 and 6, a first solder joint 51 is disposed on a side surface of the spring body 5, and a gold plating area 43 is disposed at an end of the flexible circuit board 4 located in the first accommodating cavity (as shown in fig. 8). The opposite side of the projectile body 5 is provided with a second weld 52.
Specifically, between the flexible circuit board 4 and the elastic sheet body 5, the contact between the gold-plated area 43 and the first welding point 51 realizes the electrical connection between the flexible circuit board 4 and the elastic sheet body 5. Since the first metal casing 1 is a metal antenna, the first metal casing 1 may directly contact the second welding point 52, so as to achieve electrical connection with the elastic sheet body 5.
Further, in the present embodiment, the gold plating area 43 is directly provided on the flexible wiring board 4 for communication with the elastic sheet body 5. No other parts are needed for communicating the flexible circuit board 4 with the elastic sheet body 5, so that the space is saved and the compact layout is realized.
As shown in fig. 7, a connector 41 is provided at one end of the flexible circuit board 4 located in the second accommodating chamber.
Specifically, the connector 41 serves as a conductive member, and the flexible wiring board 4 can be made to communicate with the circuit board 6 through the connector 41. Thus, signal transmission between the first housing 1 and the circuit board 6 is finally achieved by conduction between the connector 41 and the circuit board 6.
Further, the end of the flexible wiring board 4 located in the second accommodation chamber is also provided with a circuit element 42. The circuit element 42 can be connected with the circuit board 6 through the connector 41, that is, the flexible circuit board 4 can realize an integrated matching function with the circuit board 6, so as to reduce the occupied area of components on the circuit board 6. Further, the circuit element 42 may be a matching circuit of the antenna so as to adjust the frequency of the radio frequency signal, so that the matching circuit of the antenna is disposed on the flexible circuit board 4, which can reduce the area of the circuit board 6 and facilitate the miniaturization design of the wire control structure. These are not available with circular coaxial cables.
Referring to fig. 9 and 10, the insulating frame 3 is provided with a fixing hole 31, and preferably, the fixing hole 31 is formed at a position where the insulating frame 3 is assembled with the flexible circuit board 4.
Specifically, during the assembly process, the flexible wiring board 4 may be passed through the fixing hole 31 to communicate the first metal case 1, the circuit board 6 located at both sides of the insulating frame 3. Further, the flexible wiring board 4 can be fixed in the fixing hole 31 to avoid the problem of loosening of the flexible wiring board 4 during assembly and operation.
Referring to fig. 1 to 10, a first metal housing 1 and a second housing 2 are both sleeved on an insulating frame. In addition, in order to ensure the firmness of the structure, the first metal shell 1, the second shell 2 and the insulating frame 3 can be in interference fit.
Specifically, during assembly, it is generally necessary to apply glue to the insulating frame 3 first, and then to interference-fit the first metal shell 1 and the second shell 2 to the insulating frame 3. Therefore, through the interference fit between the first metal shell 1 and the second shell 2 and the adhesion of glue to the first metal shell 1 and the second shell 2, the assembly between the first metal shell 1 and the second shell 2 and the insulating frame 3 is firmer.
Preferably, the insulating frame 3 is provided with a partition strip 32. Also, the partition strip 32 may be an annular strip surrounding the insulating frame 3, and the first metal case 1 and the second case 2 are spaced apart by the partition strip 32. Therefore, the second shell 2 does not interfere with the signal transmission of the first metal shell 1, and the antenna is more convenient to debug.
The second housing 2 may be made of metal, plastic, or other materials, which is not limited in the present invention.
The wire control structure of the present invention can be applied to a bluetooth headset, and for this reason, the present invention further provides a bluetooth headset, which includes the wire control structure described above, and further includes a sound emitting speaker that is connected to the wire control structure through a wire, which belongs to the common knowledge of those skilled in the art, and is not specifically described herein.
While certain specific embodiments of the invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
