Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a plug-in structure and a wireless transmitter and receiver. Background Technology

[0002] Currently, the fixing method of plug-in structures (such as USB plug-in structures) on the market mainly relies on the tight fit of the small data connection springs between the plug and the socket. This results in relatively weak insertion and removal force, making it prone to loosening and detachment, and failing to meet the requirements of microphones for connection stability and anti-shake properties. If a 3.5mm plug is used, the common practice in the market is to design threads on the 3.5mm socket and equip the 3.5mm plug with a nut to secure it. However, while this fixing method prevents the plug from being pulled out, it cannot effectively prevent it from rotating and loosening. Utility Model Content

[0003] The purpose of this invention is to provide a plug-in structure and a wireless transmitter and receiver, which aims to solve the problems of instability such as easy loosening and dislodgement of existing plug-in structures.

[0041] Please see Figure 1-5 This utility model embodiment provides a plug-in structure, including:

[0042] The female connector 1 is provided with a plug-in interface, and the plug-in interface is provided with a flexible snap-fit ​​component;

[0043] The male connector 2 is used to be inserted into the connector interface, and the outer wall of the male connector 2 is provided with a limiting part 211;

[0044] The flexible snap-fit ​​component is used to snap into the limiting part 211 when the male connector 2 is inserted into the connector, so as to fix the female connector 1 and the male connector 2 in place.

[0045] In this embodiment, a flexible snap-fit ​​component is specially provided inside the insertion interface of the female connector 1. The main function of this flexible snap-fit ​​component is to provide a certain elastic snap-fit ​​force when the male connector 2 is inserted into the insertion interface, so as to achieve snap-fit ​​and limiting cooperation with the limiting part 211 on the outer wall of the male connector 2, thereby making the male connector 2 stably inserted into the insertion interface of the female connector 1.

[0046] Specifically, when the male connector 2 is inserted into the connector, the elastic locking member undergoes a certain elastic deformation due to the insertion of the male connector 2. This deformation allows the elastic locking member to effectively engage with the limiting part 211 on the outer wall of the male connector 2. In this way, the male connector 2 and the female connector 1 can be more tightly and securely connected together, ensuring that the male connector 2 will not experience wire breakage or interference due to shaking. At the same time, the direction of withdrawal is limited by the elastic locking member, making it more stable and preventing rotation compared to traditional 3.5 plugs. Meanwhile, the female connector 1 can also be used for charging and data connection.

[0047] like Figure 4As shown, in one embodiment, the female connector 1 includes a bottom shell 17, on which a connector is formed; the elastic snap-fit ​​member includes two spring pieces 16, which are installed in the bottom shell 17 and located on opposite sides of the connector, with a portion of the spring pieces 16 extending into the connector; the spring pieces 16 are used to elastically snap into the limiting part 211 when the male connector 2 is inserted into the connector.

[0048] In this embodiment, the design of the female connector 1 includes a base shell 17 structure. The interior of the base shell 17 structure is used to accommodate various components, and an insertion interface is opened on the outer side of the base shell 17 structure. The insertion interface is the key part for the insertion and connection of the male connector 2. To ensure that the male connector 2 can be firmly fixed when inserted into the insertion interface, the elastic locking element is designed as two spring pieces 16. The two spring pieces 16 are installed inside the base shell 17, and their positions are located on opposite sides of the insertion interface. This layout ensures that a portion of each of the two spring pieces 16 can effectively extend into the opposite sides of the insertion interface. When the male connector 2 is inserted into the insertion interface, the portion of the spring piece 16 extending into the insertion interface will perform its elastic locking function. Specifically, this portion of the spring piece 16 will contact the limiting part 211 on the male connector 2 and achieve locking through its elastic properties. This locking method not only ensures that the male connector 2 is stable in the insertion interface, but also prevents accidental dislodgement to a certain extent, thereby improving the overall reliability and stability of the connection.

[0049] Continue reading Figure 4 In one embodiment, the bottom shell 17 is provided with a positioning post and a limiting baffle; one end of the spring piece 16 is fitted onto the positioning post, the limiting baffle is located on both sides of the spring piece 16 in the length direction and abuts against the spring piece 16, and the other end of the spring piece 16 extends into the insertion interface.

[0050] In this embodiment, the positioning post and limiting baffles ensure a more secure installation of the spring piece 16 and limit its range of movement, guaranteeing stable operation. Specifically, the positioning post provides a fulcrum for one end of the spring piece 16, which is fitted onto the post, allowing for accurate positioning and preventing performance issues caused by installation deviations. The limiting baffles, located on both sides of the spring piece 16's length, hold it in place, preventing unnecessary loosening during use and enhancing its stability and durability. This also allows the other end of the spring piece 16 to be stably inserted into the connector and remain stable.

[0051] In one embodiment, the other end of the spring 16 is bent, and the bent portion extends into the insertion interface.

[0052] In this embodiment, the other end of the spring contact 16 is bent, and the bent portion has a smooth bending surface. After the bent portion engages with the limiting part 211 of the male connector 2, jamming is avoided when inserting or removing the male connector 2, making the operation smoother. At the same time, the smooth bending surface can effectively disperse the stress generated during insertion and removal, protecting the spring contact 16 and the male connector 2 from damage and extending their service life. In addition, this design makes the contact between the spring contact 16 and the male connector 2 tighter, improving the stability of the connection and the signal transmission quality. Therefore, this plug-in structure is not only easy to operate, but also has excellent durability and performance.

[0053] In one embodiment, the female connector 1 further includes:

[0054] Circuit board 13 is disposed inside bottom shell 17;

[0055] USB female connector 14 is mounted on circuit board 13 and located in the plug interface;

[0056] The fixing cover 15 is disposed inside the bottom shell 17 and surrounds the outside of the USB female connector 14;

[0057] The front cover 11 is mounted on the bottom cover 17 to enclose the components inside the bottom cover 17.

[0058] In this embodiment, the circuit board 13, as the core component of the female connector 1, bears the important functions of circuit connection and control. The circuit board 13 is fixed to the bottom shell 17 by screws 12. The USB female connector 14 is soldered to the circuit board 13 and located in the interface, facilitating electrical connection after the male connector 2 is inserted, ensuring a good electrical connection. The fixing cover 15 further enhances the stability and protection of the USB female connector 14, preventing it from being affected by external interference or damage during use. The front cover 11 serves as a sealing cover for the bottom shell 17, effectively encapsulating the internal components of the bottom shell 17 and preventing external factors such as dust and moisture from corroding the internal circuitry, thereby ensuring the long-term stable operation of the female connector 1.

[0059] In one embodiment, the spring 16 is made of metal.

[0060] In this embodiment, the metal spring 16 has good mechanical strength, which can ensure a stable connection between the male connector 2 and the female connector 1. At the same time, the metal spring 16 also has a certain degree of elasticity and wear resistance, which can maintain a stable locking pressure during long-term use and reduce the loosening of the male connector 2 due to loose locking.

[0061] In one embodiment, the male connector 2 includes:

[0062] Connector body 24;

[0063] The USB male connector 22 is located at one end of the plug-in body 24;

[0064] Plug 21, fitted onto USB male connector 22;

[0065] The outer adhesive layer 23 covers a portion of the USB male connector 22 and the plug sleeve 21, so that the USB male connector 22 and the plug sleeve 21 are integrally connected and fixed.

[0066] In this embodiment, the plug-in rod body 24 is the main component for sound acquisition. The USB male connector 22 and the outer adhesive layer 23 of the plug sleeve 21 are integrated at one end of the plug-in rod body 24, forming a plug for insertion into the plug interface. After insertion, the USB male connector 22 can be electrically connected to the USB female connector 14.

[0067] Specifically, the design of the connector sleeve 21 enhances the stability and connection effect of the USB male connector 22, preventing damage or loosening of the USB male connector 22 due to external forces during the connection process. The outer adhesive layer 23 further strengthens the connection between the USB male connector 22 and the connector sleeve 21, while also improving the overall durability and waterproof performance of the male connector 2, enabling it to better adapt to various complex usage environments.

[0068] Specifically, the connector 21 can be made of metal, such as stainless steel or aluminum alloy, to improve its hardness and wear resistance, thereby better protecting the USB male connector 22.

[0069] In one embodiment, the limiting portion 211 includes limiting recesses formed on the outer walls of opposite sides of the plug sleeve 21.

[0070] In this embodiment, the two limiting notches are designed to engage with the portions of the two spring contacts 16 that extend into the connector, thereby limiting the rotation and wobbling of the male connector 2 and further improving the stability and reliability of the connection. During the connection process, the limiting notches can accurately align with the two spring contacts 16 inside the connector, ensuring that the male connector 2 can be securely inserted and maintain the correct connection orientation.

[0071] In one embodiment, the plug sleeve 21 is tapered and adapted to the shape of the plug interface.

[0072] In this embodiment, the tapered design of the plug sleeve 21 not only facilitates the smooth insertion of the male plug 2 into the plug interface, but also acts as a guide during the insertion process, ensuring accurate and rapid mating between the plug sleeve 21 and the plug interface. Simultaneously, the tapered plug sleeve 21 provides a certain tightening force after insertion, further enhancing the stability of the insertion. Furthermore, the tapered design of the plug sleeve 21 effectively reduces frictional resistance during insertion, protecting the plug interface and plug sleeve 21 from damage and extending their service life.

[0073] This utility model embodiment also provides a wireless transmitter and receiver, including the plug-in structure described above.

[0074] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
