Description

Technical Field

[0001] This utility model relates to the field of JACK audio connector technology, and in particular to a JACK audio connector. Background Technology

[0002] JACK audio connectors are widely used interfaces for audio signal transmission, commonly found in headphones, microphones, musical instruments, and audio equipment. They are typically available in three sizes: 6.35mm (1 / 4 inch), 3.5mm (1 / 8 inch), and 2.5mm (less common). Furthermore, based on the number of contact poles, they are also classified as TS (mono), TRS (stereo or balanced), and TRRS (with microphone or video signal).

[0003] Existing JACK connectors typically use adhesive bonding to fix the terminals to the connector's plastic housing during terminal installation. After bonding, the terminals and plastic housing usually need to be left to stand for a period of time to allow the adhesive to cool. Although this method is convenient, the curing time is too long. During the curing time, clamps are also needed to fix the terminals to prevent terminal pin misalignment, resulting in low efficiency. Therefore, this application proposes a JACK audio connector to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is achieved through the following means: A JACK audio connector includes a plastic shell and a terminal connection group. The terminal connection group includes a tip connection end, a ground connection end, and a side connection end. A socket is provided in the middle of one side of the plastic shell. The tip connection ends are distributed at both ends of the side of the plastic shell away from the socket. A square socket matching the tip connection end is provided near the tip connection end of the plastic shell. An elastic tongue is provided at the lower end of the tip connection end. A bayonet is provided on the side wall of the plastic shell near the elastic tongue. A deep opening matching the elastic tongue is provided near the square socket near the elastic tongue. The deep opening extends towards the bayonet but is not conductive. The side connection ends are staggered on both sides of the top surface of the plastic shell. The ground connection end is installed on one side of the top surface of the plastic shell near the socket opening. Matching positioning slots are provided on the top surface of the plastic shell near the side connection ends and the ground connection end. Pressing protrusions are provided on both sides of the side connection ends and the ground connection end. The pressing protrusions are interference-fitted with the side wall of the positioning slot.

[0005] In a further embodiment of the above description, the tip connecting end near the socket has a bent portion, and a tip trigger spring is provided on the side of the bent portion away from the tip connecting end. The plastic shell near the tip trigger spring has a movable groove that matches the tip trigger spring. The movable groove communicates with the end of the socket away from the open side. The tip connecting end away from the bent portion has a first connecting foot. The first connecting foot bends and extends toward the two sides of the plastic shell. The two sides of the plastic shell near the first connecting foot have movable positions that match the first connecting foot. The tip trigger spring is used to contact the metal post on the headphone connector to achieve a conductive fit. The first connecting foot is used to connect to the circuit board during installation of this utility model.

[0006] In a further embodiment of the above description, protrusions are provided on both sides of the plastic shell near the side connection end and the ground connection end. A directional guide groove is provided on the side of the protrusion away from the plastic shell. A recess is provided near the protrusion on the slot of the positioning slot. A second connecting foot and a third connecting foot are respectively provided on the top surface of the side connection end and the ground connection end near the recess. The second connecting foot and the third connecting foot both bypass the recess and cooperate with the positioning guide groove. The directional guide groove on the protrusion is used to limit the second connecting foot and the third connecting foot, and also to ensure the connection stability between the side connection end and the ground connection end and the plastic shell.

[0007] In a further embodiment of the above description, the top surface of the plastic shell is provided with a conductive groove near the positioning slot of the side connection end. The conductive groove is connected to the socket. A side wall contact spring is provided in the conductive groove. The lower end of the side wall contact spring is integrally connected to the lower end of the side connection end. A hemispherical protrusion is provided on the side of the side wall contact spring near the socket. A semi-circular groove matching the hemispherical protrusion is provided at the groove opening of the conductive groove near the hemispherical protrusion. The side wall contact spring and the hemispherical protrusion are used to contact the metal post on the headphone connector to achieve a conductive effect.

[0008] In the above description, as a further embodiment, the top surface of the plastic shell is provided with an extension groove near the positioning slot of the ground wire connection end. The extension groove extends near the opening side of the plug hole. The upper end of the extension groove is provided with a connecting groove near the opening side of the plug hole. The connecting groove extends in the direction of the opening side of the plug hole. The upper end of the extension groove is provided with a guide bend near the connecting groove.

[0009] In a further embodiment of the above description, a ground contact spring is provided on the open side of the socket near the connecting slot. The end of the ground contact spring near the connecting slot extends towards the connecting slot. A connecting plate is provided at the bottom of the extension slot. One end of the connecting plate is integrally connected to the ground contact spring, and the end of the connecting plate away from the ground contact spring is integrally connected to the ground connection end. The ground contact spring and the connecting plate are connected to the ground connection end, so that the ground connection end contacts the metal post on the headphone connector to achieve the conduction effect.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the design of the square socket, an elastic tongue is provided at the lower end of the pointed connecting end during insertion, and matching positioning slots are provided on the top surface of the plastic shell near the side connecting end and the ground connecting end. Both sides of the side connecting end and the ground connecting end are provided with clamping protrusions. During installation, simply press the pointed connecting part into the square socket, and the elastic tongue contacts the bridging part between the insertion port and the bayonet, causing the elastic tongue to deform until it enters the bayonet area. Then, the elastic tongue returns to its original position and mates with the bayonet wall, thus installing the pointed connecting end. The side connecting end and the ground connecting end are installed by interference fit between the clamping protrusions and the side wall of the slot, eliminating the need for adhesive fixation. This allows for rapid assembly and improves work efficiency. Attached Figure Description
