Detailed implementation manners

[0031] For the convenience of those skilled in the art to understand the present utility model, the present utility model will be further described below in conjunction with the drawings. It should be understood that the specific implementation manners described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] Figures 1 to 10 Schematically shows the inlaid headphone tail plug of the present utility model.

[0033] As Figures 1 to 10 shown, the inlaid headphone tail plug of the present utility model includes an insulating base 10 and terminals. The terminals are positive terminals 20 or negative terminals 30 or functional terminals 50. One end of the positive terminal 20 is connected to the functional terminal 50, and one end of the negative terminal 30 is connected to the functional terminal 50. The terminals are arranged on the insulating base 10. The terminal includes a contact part 101 for contact connection with an external charging device, an inlaid part 102 for inlaid molding, and a connecting part 103 for connection with an external PCB board. The two ends of the inlaid part 102 are respectively connected to the contact part 101 and the connecting part 103. The inlaid part 102 is inlaid and molded inside the insulating base 10. Parts of the contact part 101 and the connecting part 103 are exposed outside the insulating base 10, and a clamping part 104 is arranged on the connecting part 103. The contact part 101 and the connecting part 103 can be separately connected to external components and can present different functions at different positions. By inlaying and molding the inlaid part 102 inside the insulating base 10, the terminal and the insulating base 10 are integrally formed, so that the terminal and the insulating base 10 do not need to be assembled, saving the assembly process and technology, and effectively solving the problems of inaccurate size control and poor consistency when the terminal and the insulating base 10 are assembled.

[0034] Among them, the clamping part 104 is exposed outside the insulating seat 10. The clamping part 104 includes symmetrically arranged first cards 1041 and second cards 1042. In this embodiment, two pairs of first cards 1041 and second cards 1042 are adopted. A card slot 105 with an upward opening is provided between the first card 1041 and the second card 1042. Through the combined design of the clamping part 104 and the card slot 105, it is convenient to connect with the PCB board, and a clamping connection with the PCB board can be realized, so that there is no need for wiring and soldering between the terminal and the PCB board, no need for soldering positioning, and the operation is simple.

[0035] The outer surface of the contact part 101 is provided with a contact surface 106 for contact connection with an external charging base. As Figures 9 to 10 shown, the contact part 101 has a spherical arc surface structure, the contact surface 106 is a spherical arc surface, and both are spherical arc surfaces with a diameter of 1.8 - 2.0. Another implementation manner is that, as Figures 2 to 4 shown, the contact part 101 has an elliptical spherical arc surface structure, the contact surface 106 is an elliptical spherical arc curved surface, and both are 1 / 4 elliptical spherical arc curved surfaces. Through the above two different shape designs of the contact part 101 and the contact surface 106, the contact area of the contact surface 106 can be increased, and the contact can be made more stable.

[0036] In this embodiment, there are four terminals. One positive terminal 20, one negative terminal 30, and two functional terminals 50. One end of the positive terminal 20 is connected to the functional terminal 50, one end of the negative terminal 30 is connected to the functional terminal 50, and then the positive terminal 20, the functional terminal 50, the negative terminal 30, and the functional terminal 50 are arranged around the insulating seat 10 in sequence. Two opposite terminals are in contact connection with the external charging base. The contact part 101 of the functional terminal 50 is provided with a through hole 51 that penetrates both the inside and outside of the contact part 101. This through hole 51 can be used to make way for wiring when assembling the Bluetooth headset, and can also be used for installation positioning to facilitate more stable positioning of the tail plug structure.

[0037] The functional terminal 50 can be connected to the positive terminal 20 or the negative terminal 30 in different directions and can form a loop. There can be different cross - loop ways between the terminals. For example, the positive terminal 20 and the negative terminal 30 form a loop, the positive terminal 20 and the functional terminal 50 connected to the negative terminal 30 form a loop, and the negative terminal 30 and the functional terminal 50 connected to the positive terminal 20 form a loop.

[0038] In the above embodiments, the insulating seat 10 is a plastic seat, or other insulating materials can also be used.

[0039] The manufacturing process of the earphone tail plug of the present utility model is roughly as follows:

[0040] First, the positive terminal 20, the negative terminal 30, and the functional terminal 50 are obtained by hardware stamping.

[0041] Secondly, the negative terminal 30 and the functional terminal 50 are riveted together to form a set of terminals with negative electrode functions; the positive terminal 20 and the functional terminal 50 are riveted together to form a set of terminals with positive electrode functions.

[0042] Finally, the positive terminal 20, the negative terminal 30, and the functional terminal 50 are integrally injection-molded with plastic, so that the four terminals are integrally embedded in the plastic seat 10. Then, the earphone plug in the embodiment of the present invention is formed.

[0043] The earphone plug of the present invention mainly realizes the integral structure of the terminal and the insulating seat 10 by injection-molding the embedding part 102 of the terminal in the insulating seat 10, so that the terminal and the insulating seat 10 are integrally formed. Thereby, the assembly of the terminal and the insulating seat 10 is not required, the assembly process and technology are omitted, and the problems of inaccurate size control and poor consistency during the assembly of the terminal and the insulating seat 10 can be effectively solved.

[0044] In addition, it should be noted that unless otherwise specified, the terms "first", "second", "third", etc. in the specification are only used to distinguish each component, element, step, etc. in the specification, rather than to represent the logical relationship or sequential relationship between each component, element, step, etc. In the description of the present invention, the terms "upper", "lower", "vertical", "horizontal", "perpendicular", "top", "bottom", "inner", "outer", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0045] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
