[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0026] Please refer to Figures 1-4 ;

[0027] The earphone female socket in the embodiment is the same as the components of the prior art product, specifically comprising a shell 1 and a plurality of PIN needles 2, the number of the PIN needles 2 is specifically determined according to the function of the earphone, but at least three, and if the earphone is of complete function, it usually has four PIN needles 2, each PIN needle 2 is divided into three parts, including a transmission part 21, a connection part one 22 and a connection part two 23, wherein the connection part one 22 and the connection part two 23 are located at two ends of the transmission part 21, more specifically, the transmission part 21, the connection part one 22 and the connection part two 23 are integrally formed, wherein the connection part one 22 is used for connecting with the plug of the earphone, and the connection part two 23 is used for connecting with the circuit board and other devices.

[0028] In the production process, the shell 1 is usually formed by injection molding, in the prior art, the PIN needles 2 are usually installed on the shell 1 after the shell 1 is injection molded, the steps are relatively complicated, and in the embodiment, the PIN needles 2 are placed in the mold, and then the shell 1 is formed by injection molding, so that the PIN needles 2 and the shell 1 are fully combined together, not only the connection between the PIN needles 2 and the shell 1 is more firm, but also the subsequent installation steps can be omitted, and the production efficiency is greatly improved.

[0029] Because the PIN needles 2 are very small, how to stably and tightly put the PIN needles 2 into the mold is a difficult problem, and the mold cannot be too complex, therefore, the PIN needles 2 in the utility model abandon the traditional three-dimensional distribution structure, adopt the mode that a plurality of transmission parts 21 are horizontally arranged side by side, so that a plurality of PIN needles 2 can be horizontally arranged in the mold core with the transmission part 21 as the fixed point, and by injection molding, the PIN needles 2 can be embedded in the shell 1, the structure for fixing the PIN needles 2 in the mold can be reduced, the mold structure becomes simple, and it needs to be noted that the distribution mode of the connection part one 22 and the connection part two 23 is not limited in the embodiment.

[0030] In the embodiment of the utility model, the connecting part one 22 is a bent elastic sheet, the shell 1 is provided with an empty position 12 corresponding to the position of the connecting part one 22, the shell 1 is provided with a plug-in hole 11, and the connecting end of the earphone enters the plug-in hole 11 and will be in contact with the connecting part one 22; at this time, the empty position 12 can provide a deformation space for the connecting part one 22.

[0031] In addition, the empty position 12 penetrates the side wall of the shell 1 to form a through hole, and in some products, an outer cover needs to be sleeved on the outer periphery of the shell 1; at this time, the empty position 12 can be used as a clamping position for fixing the outer cover.

[0032] In the embodiment of the utility model, the shell 1 is in a cylindrical shape, and the position corresponding to the empty position 12 is provided with an inwardly recessed planar groove 13; in the embodiment, the shell 1 includes a front end part 14 and a shell body 15; according to the requirements of different products, the position of the connecting part one 22 will change, and the corresponding empty position 12 will also change accordingly; therefore, the empty position 12 is entirely arranged on the shell body 15 or partially arranged on the shell body 15 and partially arranged on the front end part 14; however, no matter which way is adopted, the planar groove 13 is arranged on the shell body 15.

[0033] The arrangement of the planar groove 13 can not only provide a clamping fixing position for the subsequent outer periphery, but also change the stress distribution of the shell 1; a raised reinforcing rib 18 is formed between adjacent planar grooves 13 to further strengthen the strength of the shell 1.

[0034] Preferably, the shell 1 is provided with clamping grooves 16 on both sides, which are also used for fixing the outer cover.

[0035] In the embodiment of the utility model, since the plurality of transmission parts 21 are arranged horizontally and side by side, the horizontal and parallel arrangement of the plurality of connecting parts two 23 becomes very simple; the arrangement of the connecting parts is more convenient for connecting with external components; in the prior art, due to the irregular distribution of the PIN pins 2, the plurality of connecting parts two 23 are not in the same plane, and therefore it is very difficult to connect with external components; it should be noted that the above-mentioned connecting mode is not plug-in type, and the welding mode is usually adopted; the external component is usually a guide wire; since the plurality of connecting parts two 23 in the prior art are in non-planar distribution, it is difficult to complete the welding at one time; in the embodiment of the utility model, the plurality of connecting parts two 23 are arranged horizontally and side by side; the plurality of guide wires can be arranged horizontally in advance, and then the welding equipment is pressed downward to connect the plurality of guide wires and the plurality of connecting parts two 23 together, thereby greatly improving the installation efficiency.

[0036] Preferably, the end part of the shell 1 is provided with a planar boss 17, and the plurality of connecting parts two 23 are arranged on the planar boss 17; the planar boss 17 provides support for the plurality of connecting parts two 23 to prevent deformation during welding.

[0037] In this embodiment of the present invention, a plurality of connecting parts 22 are arranged in a straight line. Preferably, the plurality of connecting parts 22 are located between a plurality of transmission parts 21, and the transmission parts 21 are exposed in the planar groove 13. Based on the above embodiments, here is an example of a way to fix the PIN pin 2 in a mold. First, the formed housing 1 will have a plug hole 11, and the connecting part 22 will protrude from the plug hole 11. Therefore, a forming core is provided in the mold. The surface of the forming core is provided with a plurality of slots that are suitable for the connecting part 22. In addition, a plurality of ejector pins are provided that are adapted to the clearance position 12 and the planar groove 13. These ejector pins correspond to the other side of the transmission part 21 and the connecting part 22. There are also ejector pins 2 for corresponding to the connecting part 23.

[0038] During operation, the forming pin and ejector pin 1 abut against both sides of the connecting part 1 22, and ejector pin 1 also abuts against one side of the transmission part 21, thereby fixing the PIN pin 2. Then, the injection molding of the housing 1 begins. After completion, the forming pin, ejector pin 1 and ejector pin 2 can be pulled out.

[0039] Based on the above arrangement of PIN pins 2, the mold structure can be made very simple, so that the shell 1 is formed on the PIN pins 2, and the two are firmly fixed, which greatly improves the work efficiency.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
