Description

TECHNICAL FIELD

[0001] The present application relates to the field of TYPE-C female connector technology, in particular to a simplified implementation method of a TYPE-C female connector for transmitting analog audio signals, which is mainly used for transmitting analog audio signals on earphones. BACKGROUND

[0002] Type-C connector is a multifunctional connection interface, which can be used for data transmission, power supply and audio / video (A / V) applications. Due to its slim profile and durability, Type-C connector is very suitable for mobile devices, and has been widely used in smart phones, tablets, laptops, displays and other electronic devices.

[0003] At present, Type-C connector is also applied to small electronic products such as earphones. In fact, applying Type-C connector to earphone field does not need to use all the functions of Type-C connector, and if a standard USB2.0 TYPE-C 16 PIN female connector or USB TYPE-C 24 PIN female connector is directly applied to earphones, it will be too high in cost and not conducive to popularization. Therefore, some TYPE-C female connectors for earphones and other small electronic products have appeared in the industry, such as CN 214589415U discloses a TYPE-C dustproof connector female seat, which comprises a shell and a rear cover, and a contact part is arranged inside the shell. The transmission conductor group is welded on the upper and lower ends of the contact part, the number of terminals is reduced, and the pins not needed for earphone function are saved. Compared with the prior art, the structure is simplified, the raw materials are saved, and the manufacturing cost is reduced.

[0004] However, because the terminal contacts have upper and lower rows, although the total number of terminals is reduced, the industry still generally uses upper and lower rows of terminals to manufacture the simplified TYPE-C female connector for earphones, which requires two terminal material strips, and the material strip produces more waste. In addition, during production and manufacturing, the two terminal material strips still need to be punched and bent respectively, and when the two terminal material strips are fed into the injection mold for injection molding, the two terminal material strips still need to be positioned. Compared with the standard USB2.0 TYPE-C 16 PIN female connector or USB TYPE-C 24 PIN female connector, the number of terminals is only reduced, the manufacturing process is basically the same, and the production difficulty is basically the same, which makes it difficult to further reduce the production cost, and is not conducive to the popularization and promotion of TYPE-C female connector in earphones and other small electronic products.

[0005] Therefore, it is necessary to research a new technical solution to solve the above problems. SUMMARY

[0006] In view of the above, the present application aims at the existing problems in the prior art, and the main purpose is to provide a simplified implementation method of a TYPE-C female head for transmitting analog audio signals, which arranges two terminal groups side by side on the same main material belt, and cleverly arranges the upper and lower terminal groups on the same continuous material belt by folding, reduces the number of parts, is easy to injection molding, reduces the difficulty of product production, and reduces the production cost.

A stacking positioning part is integrally arranged between the rear end of the B6 terminal and the main material belt, the folding process of the expansion material belt is divided into two steps: first fold the expansion material belt upward and leftward by 90±5 degrees, and then fold it downward and leftward to stack on the stacking positioning part, which is usually parallel.

In this way, the problem of collision between the second terminal group and the first terminal group during bending is avoided.

[0066] Further, the first front end extension F4 comprises a first horizontal extension body F41 and a first bending portion F42, the first bending portion F42 is arranged to extend forward and upwardly from the front end of the first contact portion F3 (forming a Z-shaped bending), that is, the rear end of the first bending portion F42 is integrally connected to the front end of the first contact portion F3, the first horizontal extension body F41 is connected to the front end of the first bending portion F42, so that the first horizontal extension body F41 is higher than the first contact portion F3, the top of the rear section of the first horizontal extension body F41 is designed to be thin, such as the thin portion F401 shown in the figure; the front end of the first horizontal extension body F41 is connected to the first sub material belt 5; and the second front end extension G4 comprises a second horizontal extension body G41 and a second bending portion G42, the second bending portion G42 is arranged to extend forward and upwardly from the front end of the second contact portion G3 (forming a Z-shaped bending), that is, the rear end of the second bending portion G42 is integrally connected to the front end of the second contact portion G3, the second horizontal extension body G41 is connected to the front end of the second bending portion G42, so that the second horizontal extension body G41 is higher than the second contact portion G3, the top of the rear section of the second horizontal extension body G41 is designed to be thin, such as the thin portion G401 shown in the figure; the front end of the second horizontal extension body G41 is connected to the second sub material belt 6; and after the expansion material belt 3 is bent, the second horizontal extension body G41 is lower than the second contact portion G3, the thin portion of the top of the rear section of the second horizontal extension body G41 is arranged downward, so that: the gap D1 between the top and bottom of the rear section of the first horizontal extension body F41 and the second horizontal extension body G41 is increased, ensuring that the upper and lower rows of terminals have enough gap at this position to prevent short circuit of the upper and lower rows of terminals (due to the failure of the first bending portion F42 and the second bending portion G42 to completely stagger, if the gap is not enough, it may cause short circuit of the upper and lower rows of terminals). And, through the arrangement of the first bending portion F42 and the second bending portion G42, the head structure of the first contact portion F3 and the second contact portion G3 is designed to be bent inwardly (the heads of the upper and lower rows of terminals are close to each other, which is equivalent to the design of the inner part of the tongue piece close to the insulating body), the gap between the first contact portion F3 and the second contact portion G3 is large, and the gap between the first bending portion F42 and the second bending portion G42 gradually decreases, until the gap between the first horizontal extension body F41 and the second horizontal extension body G41 is smaller, by sinking the first bending portion F42, the second bending portion G42, the first horizontal extension body F41 and the second horizontal extension body G41 into the inner part of the tongue piece of the insulating body, the phenomenon of PIN warping of the terminal head can be effectively prevented, even after repeated use of plugging and unplugging, the phenomenon of PIN warping will not occur.

[0067] The extension material belt 3 is bent 180±5 degrees to the left and upward. Before the bending, the horizontal height of the welding feet of the terminals of the first terminal group 2 is slightly higher than that of the terminals of the second terminal group 4. When the extension material belt 3 is bent 180 degrees upward, the horizontal height of the welding feet of the terminals of the second terminal group 4 is increased to be the same as that of the terminals of the first terminal group 2. After the bending, the terminals of the two groups are arranged in upper and lower rows, and the welding feet of all the terminals are located at the same horizontal height, which facilitates the welding of the connector and a PCB or the like.

[0068] The first horizontal extension body F41 of the B6 terminal 201 deviates to the right from the front end of the first contact part F3, so as to increase the left-right spacing D5 between the first horizontal extension body F41 of the B6 terminal 201 and the first horizontal extension body F41 of the B7 terminal 202. The second horizontal extension body G41 of the A6 terminal 401 deviates to the right from the front end of the first contact part F3, so as to increase the left-right spacing D6 between the second horizontal extension body G41 of the A6 terminal 401 and the second horizontal extension body G41 of the A7 terminal 402. After the bending of the extension material belt 3, the second horizontal extension body G41 of the A6 terminal 401 is located between the left-right spacing between the first horizontal extension body F41 of the B7 terminal 202 and the first horizontal extension body F41 of the B8 terminal 203, the second horizontal extension body G41 of the A7 terminal 402 is located between the left-right spacing between the first horizontal extension body F41 of the B7 terminal 202 and the first horizontal extension body F41 of the B6 terminal 201, and the first horizontal extension body F41 of the B6 terminal 201 is located between the left-right spacing between the first horizontal extension body F41 of the B7 terminal 202 and the second horizontal extension body G41 of the A8 terminal 403. Since the second contact part G3 of the A6 / A7 terminal in the upper row is vertically aligned with the first contact part F3 of the B7 / B6 terminal in the lower row (also referred to as the horizontal direction overlapping position), there is no supporting part in the mold in the insert molding process, which easily leads to a short circuit risk of the terminals in the upper and lower rows. In the embodiment, the first horizontal extension body F41 and the second horizontal extension body G41 are arranged side by side to the left and right (i.e., the horizontal direction staggered position), so as to facilitate the increase of the supporting part in the mold to support and position the first horizontal extension body F41 and the second horizontal extension body G41, and avoid the short circuit risk of the terminals in the upper and lower rows. It can be seen that the tongue 21 is provided with a supporting and positioning hole K1 corresponding to the top surface or the bottom surface of the first horizontal extension body F41 and the second horizontal extension body G41, which is a hole position left by the position of the supporting part in the injection mold.

[0069] Due to the configuration of the extended strip 3, the welding feet of terminals B6 201, B7 202, and B8 203 are each connected to the main strip 1 via a section of the dividing strip 101. This is equivalent to cutting and unloading the material at the front end of the dividing strip 101 during subsequent strip separation. Figure 13 As shown, the cutting line L. The rear end of the welding pin of the B6 terminal 201 is connected to the front edge of the main material strip 1 via a material distribution strip 101'. The left side of the material distribution strip 101' is integrally extended to the left and widened to form a left widening portion 102'. The distance D2 between the left widening portion 102' and the welding pin of the B7 terminal 202 is smaller than the distance D3 between the welding pin of the B6 terminal 201 and the welding pin of the B7 terminal 202. The extension material strip 3 is integrally extended to the right from the right side of the material distribution strip 101' of the welding pin of the B6 terminal 201. The rear edge of the extension material strip 3 and the front edge of the main material strip 1 maintain a groove D4. Terminals A8 403, A7 402, and A6 401 are spaced from left to right along the front edge of the extension strip 3. After the extension strip 3 is bent, the top surface of its right end overlaps the top surface of the left widening portion 102', such that terminals A6 401, A7 402, and A8 403 are arranged from left to right. The soldering pins of terminals A6 401 and A7 402 are located between the left side of the soldering pin of terminal B6 201 and the right side of the soldering pin of terminal B7 202, and the soldering pin of terminal A8 403 is located to the right of the soldering pin of terminal B6 201. The 6-pin soldering pins allow for flexible design of the spacing between adjacent pins, facilitating the soldering process.

[0070] like Figures 11 to 14 As shown, it illustrates the specific structure of another integrated TYPE-C female terminal strip.

[0071] Its and Figures 8 to 16The specific structure of the illustrated integrated TYPE-C female terminal strip is basically the same, and the main difference is that: further, the third bending part F43 (forming a similar Z-shaped bending) is integrally connected between the front end of the first horizontal extension body F41 and the first secondary strip 5, and the fourth bending part G43 (forming a similar Z-shaped bending) is integrally connected between the front end of the second horizontal extension body G41 and the second secondary strip 6. The design of the third bending part F43 and the fourth bending part G43 makes the first secondary strip 5 and the second secondary strip 6 overlap and closely fit after bending to form an effective glue sealing structure. In Example Two, the first contact part F3 to the first secondary strip 5 of the extension strip 3 of the integrated TYPE-C female terminal strip before bending is designed to bend twice, that is, the first bending part F42 and the third bending part F43, so that the horizontal height of the first horizontal extension body F41 is slightly higher than the horizontal height of the first contact part F3, and the horizontal height of the first secondary strip 5 is slightly higher than the horizontal height of the first horizontal extension body F41. Similarly, the second contact part G3 to the second secondary strip 6 of the extension strip 3 of the integrated TYPE-C female terminal strip before bending is designed to bend twice, that is, the second bending part G42 and the fourth bending part G43, so that the horizontal height of the second horizontal extension body G41 is slightly higher than the horizontal height of the second contact part G3, and the horizontal height of the second secondary strip 6 is slightly higher than the horizontal height of the second horizontal extension body G41. After the extension strip 3 of the integrated TYPE-C female terminal strip is bent by 180±5 degrees, the horizontal height of the second horizontal extension body G41 is slightly lower than the horizontal height of the second contact part G3, and the horizontal height of the second secondary strip 6 is slightly lower than the horizontal height of the second horizontal extension body G41. In this way, the upper and lower rows of terminal heads gradually approach the two secondary strips, the vertical distance between the first contact part F3 and the second contact part G3 is greater than the vertical distance between the first horizontal extension body F41 and the second horizontal extension body G41, and the first secondary strip 5 and the second secondary strip 6 are closely fitted (the vertical distance is zero). Furthermore, under the premise of adding the third bending part F43 and the fourth bending part G43, because the vertical distance between the first horizontal extension body F41 and the second horizontal extension body G41 is sufficient to prevent short circuiting of the upper and lower rows of terminals, the thinned design of the top of the rear section of the first horizontal extension body F41 can be optional, and the thinned design of the bottom of the rear section of the second horizontal extension body G41 can be optional, or only one of the opposite faces is selected to adopt the thinned design.

[0074] Furthermore, the front ends of the B6 terminal 201, B7 terminal 202 and B8 terminal 203 are all connected as the first auxiliary material band connection end J3, and the front ends of the A6 terminal 401, A7 terminal 402 and A8 terminal 403 are all connected as the second auxiliary material band connection end J4. The insulating body 200 is injection molded and fixed on the TYPE-C female head terminal group 100, the connection end J5 of the main material band, the first connection end J1 of the extension material band and the second connection end J2 of the extension material band are all exposed on the rear side of the insulating body 200, and the first auxiliary material band connection end J3 and the second auxiliary material band connection end J4 are all exposed on the front side of the tongue 21 of the insulating body 20.

[0075] The expansion material belt 3 is folded upwards around the first connection end J1 of the expansion material belt, and is arranged above the rear end of the B6 terminal 201, so that the second terminal group 4 is located above the first terminal group 2.

[0076] The tongue 21 is also provided with two metal septums 400, which are respectively located on the left and right sides of the TYPE-C female head terminal group 100, and the outer sides of the two metal septums 400 at the rear end serve as the connecting end J6 of the septum material belt. The size of the two metal septums 400 can be designed to be relatively wide. Since the B6 terminal 201, the B7 terminal, and the B8 terminal, the A6 terminal, the A7 terminal, and the A8 terminal occupy a small area (approximately less than 1 / 3 of the area) on the tongue 21, the two metal septums 400 are embedded in the tongue 21.
