Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a novel headphone jack connector. Background Technology
[0002] The female connector of a headphone jack typically includes an insulating base, multiple metal terminals, and a shield. The multiple metal terminals are mounted on the insulating base. The metal terminals are usually formed by punching metal sheets with a metal stamping die and then bending them. In existing headphone jack connectors, multiple metal terminals and shields need to be punched separately using multiple sets of metal processing dies. When assembling the multiple metal terminals and shields with the insulating base, the multiple metal terminals and shields are assembled into the insulating base from multiple different directions, such as the upper surface, lower surface, and tail end face. As a result, the mold cost is high and the assembly equipment is complex during the manufacturing of headphone jack connectors, leading to a high manufacturing cost. Utility Model Content

[0032] like Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, this utility model provides an earphone jack connector, which includes a female connector and a male connector 10. The female connector includes an insulating base 20, a first signal terminal 30, and a shielding cover 50. The insulating base 20 is made of plastic material and includes a front end face 201, an upper surface 202, and a lower surface 203 opposite to the upper surface 202. A socket 21 extending rearward from the front end face 201 is provided on the insulating base 20. The male connector 10 is inserted into the socket 21, so that multiple contact areas on the male connector 10 respectively contact and cooperate with the first signal terminal 30 and other signal terminals to realize the transmission of audio signals. On the upper surface 202 of the insulating base 20, on one side of the socket 21, there are a first mounting groove 22 and a second mounting groove 23 recessed downward from the upper surface 202. The first signal terminal 30 includes a first connecting part 31, a first elastic arm 32, and a first contact part 33. The first connecting part 31 passes through the first mounting groove 22 from top to bottom. The first elastic arm 32 is connected to the lower end of the first connecting part 31. The first contact part 33 is disposed on the first elastic arm 32 and extends into the socket 21. When the male connector 10 is inserted into the socket, the first contact part 33 contacts the contact area on the surface of the male connector 10 and conducts electrically. The first elastic arm 32 can extend from bottom to top, with its lower end connected to the lower end of the first connecting part 31. The first contact part 33 is disposed at the upper end of the first elastic arm 32, so that the first elastic arm 32 and the first connecting part 31 together form a U-shaped structure, which facilitates the full deformation of the first elastic arm 32 in the inward and outward directions. The shielding cover 50 includes a plate-shaped shielding portion 51, a first connecting wall 52, and a second connecting wall 53. The shielding portion 51 is the main body of the shielding cover 50. The shielding portion 51 covers the upper surface 202 of the insulating base 20 and is used to prevent interference from the external environment during audio signal transmission. The first connecting wall 52 is bent downward from the side of the shielding portion 51 and passes through the second mounting groove 23. The second connecting wall 53 is located in the second mounting groove 23 and is formed by bending the bottom of the first connecting wall 52 upward. The first connecting wall 52 and the second connecting wall 53 form a U-shaped structure embedded in the second mounting groove 23. Furthermore, the second connecting wall 53 and the first connecting portion 31 of the first signal terminal 30 are on the same plane.
[0033] In a preferred embodiment, the insulating base 20 is provided with two first mounting slots 22, which are located on the front and rear sides of the second mounting slot 23, respectively. That is, both first mounting slots 22 and the second mounting slot 23 are located on the same side of the slot 21. The first connecting portion 31 of the first signal terminal 30 is inserted into the first mounting slot 22 located on the front side. The female connector also includes a second signal terminal 40, which includes a second connecting portion 41, a second elastic arm 42 and a second contact portion 43. The second connecting portion 41 passes through the first mounting slot 22 located on the rear side from top to bottom. The second elastic arm 42 is located on the side of the second connecting portion 41 near the socket 21. One end of the second elastic arm 42 is connected to the second connecting portion 41, and the second contact portion 43 is located at the other end of the second elastic arm 42 and extends into the socket 21. Similar to existing technologies, the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 of this invention are all formed from metal sheet. The second connecting portion 41 of the second signal terminal 40 is on the same plane as the first connecting portion 31 and the second connecting wall 53. A long strip structure can be punched out from the second connecting portion 41, and then bent at the point where it connects to the second connecting portion 41 to form a second elastic arm 42. The end of the second elastic arm 42 away from the second connecting portion 41 is bent into a protruding structure to form a second contact portion 43.
[0034] See Figure 4 As shown, during sheet metal processing, a single punching die can be used to simultaneously process the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 on a single sheet metal. Because the shielding cover 50 is provided with a first connecting wall 52 and a second connecting wall 53, and these two connecting walls together form a U-shaped structure, the first connecting wall 52 and the second connecting wall 53 have a relatively large length dimension after unfolding, thus... Figure 4 In the unfolded state shown, the first signal terminal 30 and the second signal terminal 40 can avoid the shielding part 51 with a large area, thereby allowing the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 to be arranged on a metal plate and processed by a punching die; in addition, during assembly, the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 are all assembled onto the insulating base 20 from above, and the first connecting part 31, the second connecting part 41, and the second connecting wall 53 are all in the same plane (i.e., they are aligned in the width direction of the insulating base 20). The first signal terminal 30, the second signal terminal 40, and the shielding cover 50 are assembled onto the insulating base 20 in one go from the same direction, thereby facilitating the assembly of the female connector.
[0035] In the above embodiments, the first signal terminal 30, the shield 50, and the second signal terminal 40 are arranged sequentially from front to back on the same side of the socket 21. It should be noted that the front-to-back arrangement of the first signal terminal 30, the shield 50, and the second signal terminal 40 is not limited to the above structure. For example, the shield 50 can be placed at the front or back of the three. In other embodiments, two or more first signal terminals 30 and / or second signal terminals 40 can be arranged on the insulating base 20 on the same side of the socket 21.
[0036] In another preferred embodiment, the top of the first connecting portion 31 is bent outward to form a first connecting segment 34 placed on the upper surface 202 of the insulating base 20, and the outer end of the first connecting segment 34 is bent downward to form a first weld leg 35; the top of the second connecting portion 41 is bent outward to form a second connecting segment 44 placed on the upper surface 202 of the insulating base 20, and the outer end of the second connecting segment 44 is bent downward to form a second weld leg 45; the shielding cover 50 also includes a connecting piece 55 placed on the upper surface 202 of the insulating base 20, the inner end of the connecting piece 55 being connected to the top of the second connecting wall 53, connecting... The outer end of the piece 55 is bent downward to form a welding part 56. The first connecting section 34, the second connecting section 44, and the connecting piece 55 are all on the same plane. During assembly, the assembly equipment inserts the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 into the insulating base 20 from the same height. After the assembly equipment moves down a certain height, the first connecting section 34, the second connecting section 44, and the connecting piece 55 are simultaneously pressed against the upper surface 202 of the insulating base 20, thus assembling the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 into place at the same time, which further facilitates the assembly of the female connector. In other embodiments, the first solder foot 35, the second solder foot 45, and the welding part 56 can also be set on the same plane, which further facilitates the simultaneous punching of the first signal terminal 30, the second signal terminal 40, and the shielding cover 50 using a single punching die. The shielding cover 50 also includes an extension section 54, which connects the top of the second connecting wall 53 and the connecting piece 55. The extension section 54 extends in the front-rear direction. Specifically, the extension section 54 extends a certain length from the top of the second connecting wall 53 and then connects to the inner end of the connecting piece 55, so that the connecting piece 55 and the second connecting wall 53 are offset from each other by a certain distance in the front-rear direction. A recessed clearance 411 is provided on the second connecting portion 41 of the second signal terminal 40, which is recessed downward from its top. The extension section 54 is accommodated in the recessed clearance 411. Figure 4In its unfolded state, the presence of the first connecting wall 52 and the second connecting wall 53 on the shielding cover 50 results in a larger distance between the extension section 54 and the shielding portion 51. This allows the second connecting portion 41 of the second signal terminal 40 to be positioned between the shielding portion 51 and the welding portion 56, ensuring that the second connecting portion 41 of the second signal terminal 40 has a relatively large size. The second elastic arm 42, punched from the second connecting portion 41, has sufficient dimensions. Thus, the larger second connecting portion 41 can be stably fixed to the insulating base 20, and the longer second elastic arm 42 can have a larger elastic deformation, allowing the second contact portion 43 to stably contact the contact area on the surface of the male connector 10. The avoidance recess 411 provided on the second connecting portion 41 prevents interference between the second signal terminal 40 and the shielding cover 50. During punching, the second signal terminal 40 can be positioned as close as possible to the shielding cover 50, reducing metal waste and lowering manufacturing costs.
[0037] The insulating base 20 has three through holes 24 extending downward from its upper surface 202 and penetrating the insulating base 20. The first solder foot 35, the second solder foot 45, and the solder part 56 protrude from the bottom of the insulating base 20 after passing through the top of the three through holes 24. In this way, the first solder foot 35, the second solder foot 45, and the solder part 56 can be soldered to the corresponding terminals on the circuit board located below the insulating base 20.
[0038] The first contact portion 33 is placed on the front side of the shielding portion 51, and the second contact portion 43 is located below the shielding portion 51. By placing the first contact portion 33 on the front side of the shielding portion 51, the first contact portion 33 and the first elastic arm 32 can avoid the shielding portion 51 when the first contact portion 33 is placed on the front side of the shielding portion 51 during the punching process by the punching die.
[0039] The female connector also includes two third signal terminals 60, which are used to cooperate with the male connector 10 to transmit audio signals, thereby cooperating with the first signal terminal 30 and the second signal terminal 40 to realize the multi-channel audio signal transmission of the headphone jack connector; the insulating base 20 includes a lower surface 203 opposite to the upper surface 202, and two third mounting slots 25 are provided on the insulating base 20 on the other side of the socket 21 (i.e., the side opposite to the first mounting slot 22 and the second mounting slot 23). The third signal terminal 60 includes a third connecting part 61, a third elastic arm 62, and a third contact part 63. The third connecting parts 61 of the two third signal terminals 60 pass through the two third mounting slots 25 from bottom to top respectively; the third connecting part 61 includes a first section 611 extending from bottom to top, and the top of the first section 611 is bent inward to face towards The second segment 612 extending towards the socket 21 and the third segment 613 extending downward after being bent from the inner end of the second segment 612, thus forming an inverted U-shaped structure for the third connection portion 61 of the third signal terminal 60. The first segment 611 of the third connection portion 61 of the two third signal terminals 60 is on the same plane, the second segment 612 of the two third connection portions 61 is on the same plane, and the third segment 613 of the two third connection portions 61 is on the same plane. During assembly, the two third signal terminals 60 are respectively inserted into the two third mounting slots 25 from bottom to top. The first segment 611 and the third segment 613 are respectively close to the two side walls of the third mounting slot 25. The two third signal terminals 60 are moved upward by the assembly equipment. When the second segment 612 abuts against the top surface of the third mounting slot 25, the third signal terminal 60 is installed in place with the insulating base 20. One end of the third elastic arm 62 is connected to the lower end of the third segment 613 of the third connecting part 61, and the third contact part 63 is located at the other end of the third elastic arm 62 and extends into the socket 21. The first segment 611, the second segment 612, and the third segment 613 of the two third connecting parts 61 of the two third signal terminals 60 are respectively arranged on the same plane, so as to facilitate the processing of the two third signal terminals 60 through a set of punching dies.
[0040] The female connector also includes a switch terminal 70 and a switch terminal 80, which cooperate to detect whether the male connector 10 is inserted into the socket 21. Specifically, the switch terminal 70 includes a fourth connecting portion 71, a fourth elastic arm 72, and a mating portion 73 fixed to the insulating base 20. One end of the fourth elastic arm 72 is connected to the fourth connecting portion 71, and the mating portion 73 is located at the other end of the fourth elastic arm 72. The switch terminal 80 includes a fourth connecting portion 81 and a fourth elastic arm 82 fixed to the insulating base 20. One end of the fourth elastic arm 82 is connected to the fourth connecting portion 81, and the other end of the fourth elastic arm 82 is wrapped with an insulating block 83 that extends into the socket 21. After the switch terminals 70 and 80 are installed on the insulating base 20, the fourth elastic arm 72 is positioned outside the fourth elastic arm 82, and the mating part 73 on the fourth elastic arm 72 is positioned outside the fourth elastic arm 82. When the male connector 10 is not inserted into the socket 21, the mating part 73 does not contact the fourth elastic arm 82. When the male connector 10 is inserted into the socket 21, the male connector 10 pushes the insulating block 83 outward, causing the fourth elastic arm 82 to deform outward and contact the mating part 73 and become electrically connected. In this way, the signal changes achieved by the switch terminals 70 and 80 before and after the male connector 10 is inserted can be used to detect whether the male connector 10 is inserted into the socket 21. A fourth mounting groove 26 with an upwardly recessed shape is provided on the lower surface 203 of the insulating base 20. The fourth connecting portion 71 of the switch terminal 70 passes through the fourth mounting groove 26 from bottom to top, so that the switch terminal 70 and the two third signal terminals 60 can be assembled together from bottom to top onto the insulating base 20. Specifically, the fourth connecting portion 71 of the switch terminal 70 includes an outer vertical wall 711, an inner vertical wall 713, and a top connecting wall 712. The outer vertical wall 711, the inner vertical wall 713, and the top connecting wall 712 form a U-shape with the opening facing downwards. The outer vertical wall 711 is in the same plane as the first segment 611, the inner vertical wall 713 is in the same plane as the third segment 613, and the top connecting wall 712 is in the same plane as the second segment 612. Figure 7 As shown, during the punching process, a single die can be used to simultaneously punch out two third signal terminals 60 and switch terminals 70 from a metal sheet. At least a portion of the lower part of the first section 611 of the third connecting part 61 protrudes from the third mounting groove 25 to form a third weld foot, and at least a portion of the lower part of the outer vertical wall 711 of the fourth connecting part 71 of the switch terminal 70 protrudes from the fourth mounting groove 26 to form a weld end.
[0041] A downwardly recessed groove 27 is also provided on the upper surface 202 of the insulating base 20. The fourth connecting part 81 of the switch terminal 80 is inserted into the groove 27 from top to bottom to fix the fourth connecting part 81 on the insulating base 20.
[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
