Description

Technical Field

[0001] This application relates to the technical field of audio interfaces, and in particular to an audio interface connector. Background Technology

[0002] An audio jack is a physical interface used to connect input or output signals between audio devices. While providing a connection for audio plugs, an audio jack can transmit various audio signals and is widely used in electronic devices, professional audio equipment, communication equipment, and broadcasting equipment.

[0003] The audio socket module in the related technology includes a plug and a socket. The plug is used to connect to sound output devices such as speakers and headphones. The plug includes a plug body and a conductive rod disposed at one end of the plug body. The plug includes a signal terminal and a ground terminal along its length, with the signal terminal located at the end away from the ground terminal. The socket has a slot for inserting the conductive rod, and the slot has a first conductive part for electrical connection with the signal terminal and a second conductive part for electrical connection with the ground terminal. During the insertion of a plug into a socket, the signal terminal makes contact with the socket and conducts electricity before the ground terminal; as the plug continues to be inserted, the ground terminal then makes contact with the socket and conducts electricity. When the signal terminal is connected to the socket but the ground terminal is not, the audio output device is prone to generating noise. Utility Model Content

[0004] To address the issue of noise generation in audio output devices, this application provides an audio interface connector.

[0005] This application provides an audio interface connector, which adopts the following technical solution: An audio interface connector includes a plug module and a socket module. The plug module includes a plug body, one end of which is provided with a grounding ring and a signal rod located within the grounding ring, with a gap between the signal rod and the grounding ring. The socket module includes a base and a socket body disposed on the base. The socket body includes a grounding tube disposed on the base, which can be inserted into the grounding ring. An insulating post is disposed within the grounding tube, and a fixing groove is formed on the side of the insulating post facing the base. A fixing hole is formed on the bottom wall of the fixing groove, and a signal post is disposed within the fixing groove. A signal tube for the signal rod to be inserted is disposed on the side of the signal post facing the fixing hole. During the insertion of the plug module and the socket module, the contact point between the signal rod and the signal tube occurs after the contact point between the grounding ring and the outer surface of the grounding tube.

[0006] By adopting the above technical solution, during the process of inserting the plug module into the socket module, the signal rod is first inserted into the insulating post. As the plug module continues to move towards the base, until the grounding ring contacts and conducts with the grounding tube, the plug module continues to move towards the base, and the signal rod is inserted into the signal tube and conducts with the signal tube. The contact between the grounding ring and the grounding tube is earlier than the contact between the signal rod and the signal post, reducing the probability of noise generated by the sound output device.

[0007] Optionally, the outer circumferential surface of the insulating post is provided with a first fixing ring block, and the inner circumferential surface of the grounding pipe is provided with a first fixing ring groove for the first fixing ring block to be inserted.

[0008] By adopting the above technical solution, the insulating post is less likely to move along the axial direction of the grounding pipe, thereby increasing the stability of the connection between the insulating post and the grounding pipe.

[0009] Optionally, the outer circumferential surface of the signal post is provided with a second fixing ring block, and the inner circumferential surface of the insulating post is provided with a second fixing ring groove for the second fixing ring block to be inserted.

[0010] By adopting the above technical solution, the signal post is less likely to move along the axial direction of the insulating post, thereby increasing the stability of the connection between the signal post and the insulating post.

[0011] Optionally, the inner wall of the signal tube is provided with a receiving groove, which extends through the signal tube along the insertion direction of the signal rod.

[0012] By adopting the above technical solution, a receiving groove is provided, which allows the signal tube to deform. When the signal rod is inserted into the signal tube, the signal tube is stretched open, and the signal rod is clamped by the restoring force of the signal tube, making it difficult for the signal rod to detach from the signal tube.

[0013] Optionally, the grounding ring has a first chamfer, which is located at the junction of the end face of the grounding ring facing the base and the inner surface of the grounding tube; the grounding tube has a second chamfer, which is located at the junction of the end face of the grounding tube facing the plug body and the outer surface of the grounding ring.

[0014] By adopting the above technical solution, both the first chamfer and the second chamfer have a guiding function; the first chamfer and the second chamfer facilitate the insertion of the grounding pipe into the grounding ring.

[0015] Optionally, the base includes a support base, on which a first grounding frame is provided. The first grounding frame includes two parallel first grounding plates, and a locking structure connecting the first grounding plates and the support base is provided.

[0016] Optionally, the first grounding plate has a locking hole at one end facing the support base. The locking structure includes an elastic block disposed on the inner wall of the socket body away from the locking hole. The elastic block extends toward the support base and abuts against the bottom of the support base.

[0017] By adopting the above technical solution, the support seat is restricted by the elastic block when it moves downward, making it difficult for the support seat and the first grounding frame to separate from the first grounding plate.

[0018] Optionally, a connecting rod is fixedly connected to the end face of the signal column facing the support base. A storage slot is provided at the end of the support base away from the socket body. A conductive sheet is provided in the storage slot. An opening is provided in the bottom wall of the storage slot. The connecting rod passes through the opening and is connected to the conductive sheet.

[0019] By adopting the above technical solution, the conductive sheet is inserted into the storage slot, and the connecting rod passes through the opening and connects with the conductive sheet, so that the conductive sheet and the connecting rod are connected.

[0020] Optionally, the connecting rod is riveted to the conductive sheet.

[0021] By adopting the above technical solution, the connecting rod and the conductive sheet are less likely to separate, thus improving the stability of signal transmission between the connecting rod and the conductive sheet.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During the process of inserting the plug module into the socket module, the signal rod is first inserted into the insulating post. As the plug module continues to move towards the base, until the grounding ring contacts and conducts with the grounding tube, the plug module continues to move towards the base, and the signal rod is inserted into the signal tube and conducts with the signal tube. The contact between the grounding ring and the grounding tube is earlier than the contact between the signal rod and the signal post, reducing the probability of noise generated by the sound output device. 2. The locking structure locks the support base and the first grounding plate, reducing the probability of accidental separation between the support base and the first grounding plate; the connecting rod passes through the opening and is riveted to the conductive plate, making it difficult for the connecting rod, support base and conductive plate to separate.
