When the audio plug is inserted into the audio socket and is electrically connected with the elastic contact end of the connecting terminal, the transmission of audio signal is realized.

[0003] In the prior art, the mounting end of the connecting terminal is welded with the PCB by SMT (Surface Mount Technology), and the SMT welding is a kind of welding technology with high automation degree, which has the advantages of high production efficiency and stable welding quality. However, the SMT welding method brings certain difficulty in assembly and subsequent maintenance: in the SMT assembly process, high-precision positioning and alignment are required, so the assembly process is difficult. In addition, once the welding is completed, the connection between the connecting terminal and the PCB is relatively firm and not easy to disassemble. This leads to the fact that, in the subsequent maintenance process, if the connecting terminal needs to be replaced, the entire audio socket or even the PCB needs to be disassembled and re-welded, which increases the complexity and cost of maintenance.

[0029] Referring to Figure 1 and Figure 2 , the audio jack connector 100 shown in the drawings includes an insulating shell 10 having a plug hole 11 and a plurality of connection terminals 20, each of the plurality of connection terminals 20 has an elastic contact end 21 located in the plug hole 11, and each of the plurality of connection terminals 20 also has an elastic mounting end 22 exposed to one side of the insulating shell 10. The elastic mounting end 22 of each of the plurality of connection terminals 20 is exposed to a side surface of the insulating shell 10 facing the circuit board 200, and the elastic mounting end 22 extends obliquely to the direction of the circuit board 200. The elastic mounting end 22 elastically abuts against the circuit board 200.

[0030] The side surface (front side surface shown in the figure) of the insulating shell 10 along the axial direction thereof is formed with a socket 12, which communicates the plug-in hole 11 with the outside world, and an audio plug can be inserted into the plug-in hole 11 from the socket 12 under the action of the outside world or pulled out from the socket 12 under the action of the outside world. The plug-in hole 11 is configured as a hollow cylindrical plug-in hole, which penetrates through one side surface of the insulating shell 10 along the axial direction of the insulating shell 10.

[0031] Please refer to Figure 3 , Figure 4 and Figure 5 , the insulating shell 10 is provided with each plug-in cavity 13 for accommodating each connection terminal 20, each plug-in cavity 13 is distributed on the outer periphery of the plug-in hole 11, and each plug-in cavity 13 is separated by the hole wall of the plug-in hole 11. Each connection terminal 20 is respectively plugged into each plug-in cavity 13, wherein the part of the connection terminal 20 plugged into the plug-in cavity 13 is defined as the plug-in section 23, which is limited in the plug-in cavity 13. For example, each plug-in section 23 is formed with a barb portion 231 for clamping fit with the cavity wall of the plug-in cavity 13, and the barb portion 231 is used to press the cavity wall in the direction of the cavity wall to achieve the limiting of the plug-in section 23. Each plug-in cavity 13 has a first through port 131 communicating with the plug-in hole 11 so that the elastic contact end 21 of each connection terminal 20 extends into the plug-in hole 11, and each plug-in cavity 13 also has a second through port 132 penetrating through the insulating shell 10 towards one side surface of the circuit board 200, and each second through port 132 is used for the elastic mounting end 22 of each connection terminal 20 to extend out of the insulating shell 10 to elastically abut against the circuit board 200.

[0032] Please refer to Figure 3As an example, the structure of several connection terminals 20 is shown. The several connection terminals 20 are respectively a ground terminal 20a, a first right channel terminal 20b, a second right channel terminal 20c, a left channel terminal 20d, and a detection terminal 20e for detecting the access or disconnection of an audio plug. The ground terminal 20a, the first right channel terminal 20b, the second right channel terminal 20c, the left channel terminal 20d, and the detection terminal 20e have different shapes due to the difference in installation position. However, they all have a plug-in section 23 that is plugged into and limited in the insulating housing 10, an elastic contact end 21 that extends into the plug-in hole 11 through the first through hole 131, and an elastic mounting end 22 that extends out of the insulating housing 10 through the second through hole 132. The elastic contact end 21, the plug-in section 23, and the elastic mounting end 22 can be integrally formed, and the elastic contact end 21 and the elastic mounting end 22 are integrally connected to both ends of the plug-in section 23, respectively. The abutting surface of each elastic mounting end 22 that elastically abuts against the circuit board 200 is formed with a protruding rib 221 that extends along the axis direction of the elastic mounting end 22. The protruding rib 221 can increase the elastic abutting force and strength of the elastic mounting end 22 against the circuit board 200.

[0033] The plug-in section 23 of the ground terminal 20a has a U-shaped structure as a whole, which has a base sheet 201a and side sheets 202a formed at both ends of the base sheet 201a. The elastic contact end 21 of the ground terminal 20a is formed on one side (e.g., the front side as shown in the figure) of the base sheet 201a, integrally connected to one end of the base sheet 201a, and bent upward and backward at the other end to extend backward. The bent part extends into the plug-in hole 11 to elastically contact the audio plug, and the part extending backward forms an elastic avoiding space with the base sheet 201a. The elastic mounting end 22 of the ground terminal 20a is connected to one of the side sheets 202a at one end and extends toward the circuit board 200 and the other side sheet 202a at the other end.

The elastic mounting end 22 of the left channel terminal 20d is extended downward and inward (the right side direction as shown in the figure) from the lower end of the insertion section 23 thereof.

[0036] The detection terminal 20e is located at the right rear side of the insertion hole 11, and is composed of two separate elastic pieces 201e, 202e. One elastic piece 201e is located at the inner side, and the other elastic piece 202e is located at the outer side. The elastic contact end 21 is formed at the elastic piece 201e at the inner side, and the elastic mounting end 22 is formed at the elastic piece 202e at the outer side. The elastic piece 201e at the inner side is moved outward to contact the elastic piece 202e at the outer side after being pressed by the audio plug, so as to realize the conduction of the two elastic pieces 201e, 202e.

[0037] Please refer to Figure 4 , the insulating shell 10 is provided with a plurality of insertion cavities 13 for respectively accommodating the ground terminal 20a, the first right channel terminal 20b, the second right channel terminal 20c, the left channel terminal 20d and the detection terminal 20e, which are respectively the ground terminal insertion cavity 13a, the first right channel terminal insertion cavity 13b, the second right channel terminal insertion cavity 13c, the left channel terminal insertion cavity 13d and the detection terminal insertion cavity 13e. The shapes of the ground terminal insertion cavity 13a, the first right channel terminal insertion cavity 13b, the second right channel terminal insertion cavity 13c, the left channel terminal insertion cavity 13d and the detection terminal insertion cavity 13e are matched with the shapes of the insertion sections 23 of the respective connection terminals 20. They are penetrated through the insulating shell 10 toward one side of the circuit board 200 to form an insertion port (the second through hole 132). When the connection terminals 20 are inserted, the connection terminals 20 are inserted into the insertion cavities 13 from the insertion port, the elastic contact ends 21 of the connection terminals 20 are extended into the insertion hole 11 from the first through holes 131 of the insertion cavities 13, and the elastic mounting ends 22 of the connection terminals 20 are located outside the insertion cavities 13.

[0038] The insulating shell 10 is detachably connected to the circuit board 200, and the elastic mounting end 22 is in elastic abutment with the circuit board 200 under the pressing force of the insulating shell 10.

[0039] Please continue to refer to Figure 1In the shown embodiment, the audio socket connector 100 further comprises a housing 30 having a top wall 31 for being pressed against a side of the insulating shell 10 away from the circuit board 200 and side walls 32 formed on both sides of the top wall 31. The insulating shell 10 can be clamped to the circuit board 200 through a clamping piece 33 formed on an end of the side wall 32 towards the circuit board 200. Correspondingly, through holes are formed on the circuit board 200 at positions corresponding to the clamping pieces 33 of the two side walls 32. The clamping piece 33 can be configured as a clamping block extending from the side wall 32 towards the circuit board 200, and a clamping hook part is formed on an end of the clamping block towards the circuit board 200, which is used for abutting against a side of the circuit board 200 away from the insulating shell 10 when the clamping block is inserted into the through hole.

Compared with the traditional SMT welding method, the connection between each connection terminal 20 and the circuit board 200 can be realized only by fixing the insulating shell 10 on the corresponding position of the circuit board 200, the assembly difficulty of the connection terminal is reduced, the assembly efficiency is improved, the cost is reduced, and the replacement of components during subsequent maintenance is facilitated, and no other components are damaged during replacement of the components.
