Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an earphone jack. Background Technology

[0002] Headphone jacks are mainly used in mobile phone stereo designs, CD players, cordless phones, MP3 players, digital laptops, DVDs, and digital cameras. Many audio-visual electronic products have headphone jacks to provide audio output interfaces. The headphone plugs that are compatible with them are stepped cylindrical in shape. Each step acts as a different electrode and needs to make electrical contact with different conductive plates inside the headphone jack to achieve the purpose of connecting the left channel, right channel, microphone, and ground.

[0003] Traditional headphone jack designs often employ relatively simple mechanical structures, using physical plugging and unplugging to connect and disconnect audio signals. However, as consumers increasingly demand functionality and convenience from electronic devices, the traditional headphone jack design has gradually revealed some problems, such as limited plugging and unplugging cycles, susceptibility to damage, and unstable signal transmission.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 An earphone jack includes an upper cover 10 and a base plate 40 that are interlocked. A cavity 403 is formed on the upper end of the base plate 40, and a control component 20 is disposed on the upper end of the cavity 403. The control component 20 includes a micro switch 201. A socket body 30 is disposed on one side of the cavity 403. At least one placement groove 401 is formed on the back of the base plate 40, and a terminal 50 is embedded in the placement groove 401. The terminal 50 extends to the lower end of the micro switch 201 and covers the connecting pin 202 of the micro switch 201 to form a conductive connection. This structure mainly consists of two parts: the upper cover 10 and the base plate 40. These two parts are interlocked by a snap-fit ​​mechanism, ensuring the stability and ease of assembly of the structure. The top of the base plate 40 has a cavity 403, which not only serves as a structural support but also houses a highly integrated control component 20. The core component of the control component 20 is the micro switch 201, which is responsible for controlling the on / off state of the earphone jack. On one side of the cavity 403, a socket body 30 is embedded, specifically designed for headphone plugs to ensure a smooth plugging and unplugging experience and stable electrical connection. Furthermore, the back of the base plate 40 innovatively features at least one placement slot 401. These slots 401 not only optimize the internal layout but also provide ideal space for the installation of the terminals 50. Within these slots 401, the terminals 50 are embedded and extend to the lower end of the microswitch 201, forming a robust conductive path with the connecting pins 202 of the microswitch 201 through an encapsulation process, thereby ensuring efficient and stable signal transmission.

[0020] Specifically, the socket body 30 includes a plug-in area, and the micro switch 201 includes a button. Both the plug-in area and the button are disposed through the upper cover 10. The plug-in area is provided for inserting headphones. Furthermore, the socket integrates a micro switch 201 assembly, designed to control the circuit's on / off state with a slight touch from the user.

[0021] Specifically, a partition 103 is provided on the inner side of the upper cover 10, dividing the inner side of the upper cover 10 into two parts for accommodating the micro switch 201 and the socket body 30 respectively. The inner wall of the cavity for housing the socket body 30 is provided with multiple guide strips 102, and the inner wall of the cavity for housing the micro switch 201 is provided with retaining teeth 104. In essence, the partition 103 on the inner side of the upper cover 10 is designed to divide the internal space of the upper cover 10 into two independent and functionally defined areas, improving the rationality of the internal component layout and effectively ensuring electrical and physical isolation between components, thus enhancing the safety and stability of the overall structure. One of the partitioned areas is specifically used to accommodate the socket body 30. The inner wall of this area is provided with multiple guide strips 102. These guide strips 102 not only guide the socket body 30 in its installation position, ensuring that the socket body 30 can be stably and accurately positioned in the preset position, but also provide necessary guidance and support during insertion and removal, reducing the risk of wear or damage caused by improper operation, and improving user experience and service life. The other partition is specifically designed for the micro switch 201, with a retaining tooth structure 104 on its inner wall. These retaining teeth 104 not only provide reliable fixing points for the installation of the micro switch 201, ensuring the stability and sensitivity of the micro switch 201 under frequent operation, but also effectively prevent the micro switch 201 from loosening or shifting during use through a physical locking mechanism, further ensuring the accuracy and reliability of circuit control.

[0022] Specifically, the micro switch 201 has a connecting pin 202 at its lower end. This connecting pin 202 is electrically connected to the terminal 50 by covering it. The design of the connecting pin 202 is intended to achieve a precise and stable electrical connection with the specially designed terminal 50. Specifically, the connecting pin 202 is tightly bonded to the terminal 50 through a covering process, which ensures that the electrical conduction between the two is not only efficient but also durable and reliable. This covered electrical connection design not only improves the stability and efficiency of current transmission but also effectively prevents electrical faults caused by loosening or external interference, thereby ensuring the superior performance and long-term reliability of the headphone jack in various usage environments.

[0023] Specifically, the socket body 30 is provided with multiple pins 301 for corresponding audio channels. These pins 301 are arranged internally to ensure accurate one-to-one connection with different audio channels. Each pin 301 carries a specific audio signal transmission task, and through their arrangement and combination, they collectively construct an audio signal transmission channel. This design not only ensures the clarity and fidelity of the audio signal during transmission but also greatly enhances the user's listening experience when using the headphone jack.
