Description

Technical Field

[0001] This utility model relates to the field of TYPE-C terminals, and in particular to an integrated TYPE-C female terminal strip, which is mainly used, but not limited to, transmitting analog audio signals on headphones. Background Technology

[0002] The Type-C connector is a versatile interface used for data transmission, power supply, and audio / video (A / V) applications. Due to its slim profile and durability, the Type-C connector is ideal for mobile devices and is widely used in smartphones, tablets, laptops, monitors, and many other electronic devices.

[0003] Currently, Type-C connectors are also used in small electronic products such as headphones. However, applying Type-C connectors to headphones doesn't require using all their functions. Furthermore, directly using standard USB 2.0 Type-C 16-pin or USB Type-C 24-pin female connectors on headphones would be too costly and hinder widespread adoption. Therefore, the industry has developed Type-C female connectors for small electronic products like headphones. For example, CN 214589415U discloses a Type-C dustproof connector female connector, including a housing and a back cover. The housing has a contact portion with transmission conductor groups soldered to its upper and lower ends. This reduces the number of terminals, eliminating pins unnecessary for headphone functionality. Compared to other connectors, this simplifies the structure, saves raw materials, and reduces manufacturing costs.

[0004] However, because the terminal contacts are arranged in two rows, upper and lower, although the total number of terminals is reduced, the industry generally still uses upper and lower rows of terminals to make simplified headphone TYPE-C female connectors. This requires two terminal strips, which generate a lot of waste. In addition, during production, the two terminal strips still need to be stamped and bent separately. Furthermore, when feeding the two terminal strips into the injection mold for injection molding, the two terminal strips still need to be positioned. Compared with the standard USB 2.0 TYPE-C 16PIN female connector or USB TYPE-C 24PIN female connector, it only reduces the number of terminals, while the manufacturing process is basically the same, and the production difficulty is basically the same. This makes it difficult to further reduce production costs, which is not conducive to the promotion and popularization of TYPE-C female connectors in small electronic products such as headphones.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an integrated TYPE-C female connector strip, which cleverly combines the upper and lower rows of terminals into one, reducing the number of parts, reducing the difficulty of product manufacturing, and reducing production costs, which is conducive to the promotion and popularization of TYPE-C female connectors in small electronic products such as headphones.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An integrated TYPE-C female terminal strip includes a main strip extending left and right and a first terminal group connected to the front edge of the main strip. The first terminal group includes two or more terminals spaced left and right along the front edge of the main strip. An extension strip is also connected to the front edge of the main strip or the side of the first terminal group. The extension strip is connected to a second terminal group, which is arranged side by side with the first terminal group. The second terminal group includes two or more terminals spaced left and right along the front edge of the main strip. A foldable area is formed on the extension strip between the second terminal group and the first terminal group. The extension strip is bent in the foldable area so that the second terminal group and the first terminal group are stacked vertically and maintain a gap.

[0009] As a preferred embodiment, the rear end of the first terminal group is connected to the main material strip, and the front end of the first terminal group is connected to a first auxiliary material strip; the rear end of the second terminal group is connected to the extended material strip, and the front end of the second terminal group is connected to a second auxiliary material strip.

[0010] As a preferred embodiment, each terminal of the first terminal group includes a first welding foot, a first fixing part, a first contact part and a first front end extension part arranged sequentially from back to front. The first welding foot extends horizontally, the first fixing part extends integrally upward from the front end of the first welding foot, the first contact part extends integrally forward from the upper end of the first fixing part, and the first front end extension part extends integrally forward from the front end of the first contact part and is connected to the first auxiliary material strip.

[0011] Each terminal of the second terminal group includes a second welding foot, a second fixing part, a second contact part, and a second front end extension part arranged sequentially from back to front. The second welding foot extends horizontally, the second fixing part extends downward from the front end of the second welding foot integrally, the second contact part extends forward from the lower end of the second fixing part integrally, and the second front end extension part extends forward from the front end of the second contact part integrally and connects to the second auxiliary material strip.

[0012] As a preferred embodiment, the first front-end extension includes a first horizontally extending body and a first bending portion. The first bending portion extends forward and obliquely upward from the front end of the first contact portion. The first horizontally extending body is connected to the front end of the first bending portion, such that the first horizontally extending body is higher than the first contact portion. Furthermore, the second front-end extension includes a second horizontally extending body and a second bending portion. The second bending portion extends forward and obliquely upward from the front end of the second contact portion. The second horizontally extending body is connected to the front end of the second bending portion, such that the second horizontally extending body is higher than the second contact portion. When the extended strip is bent, the second horizontally extending body is lower than the second contact portion.

[0013] As a preferred embodiment, the top of the rear section of the first horizontal extension body is thinned, and the top of the rear section of the second horizontal extension body is also thinned. When the extension strip is bent, the top of the thinned part of the rear section of the second horizontal extension body is set downward, so that the vertical gap between the rear sections of the first horizontal extension body and the second horizontal extension body increases.

[0014] And / or:

[0015] The front end of the first horizontally extending body is integrally connected to the first secondary strip with a third bending portion, and the front end of the second horizontally extending body is integrally connected to the second secondary strip with a fourth bending portion, such that: after the extended strip is bent, the first secondary strip and the second secondary strip overlap and fit together tightly, the horizontal height of the first secondary strip is higher than the horizontal height of the first horizontally extending body, and the horizontal height of the second secondary strip is lower than the horizontal height of the second horizontally extending body.

[0016] As a preferred embodiment, the first terminal group includes terminals B6, B7, and B8 arranged from right to left, and the second terminal group includes terminals A6, A7, and A8 arranged from right to left. When the extended strip is bent upwards and to the left at 180±5 degrees, terminals A6, A7, and A8 are arranged from left to right.

[0017] As a preferred embodiment, the second sub-material strip is stacked and adhered to the top surface of the first sub-material strip, such that the vertical gap between the second sub-material strip and the first sub-material strip is zero, and thus the rear end surfaces of the second sub-material strip and the first sub-material strip together constitute the sealing surface.

[0018] As a preferred embodiment, the first horizontal extension body of the B6 terminal is offset to the right from the front end of its first contact portion to increase the left-right distance between the first horizontal extension body of the B6 terminal and the first horizontal extension body of the B7 terminal.

[0019] The second horizontal extension body of terminal A6 is offset to the right from the front end of its first contact portion to increase the left-right distance between the second horizontal extension body of terminal A6 and the second horizontal extension body of terminal A7; when the extension strip is bent, the second horizontal extension body of terminal A6 is located between the left-right distances of the first horizontal extension body of terminal B7 and the first horizontal extension body of terminal B8, the second horizontal extension body of terminal A7 is located between the left-right distances of the first horizontal extension body of terminal B7 and the first horizontal extension body of terminal B6, and the first horizontal extension body of terminal B6 is located between the left-right distances of the second horizontal extension body of terminal A7 and the second horizontal extension body of terminal A8.

[0020] As a preferred embodiment, both the second and first auxiliary strips are provided with positioning holes. When the extended strip is bent, the positioning holes of the second and first auxiliary strips are aligned vertically. Furthermore, the first auxiliary strip is widened on its side and has a positioning edge. When the extended strip is bent, the positioning edge is exposed on the outer periphery of the second auxiliary strip.

[0021] As a preferred embodiment, the rear end of the soldering pin of the B6 terminal is connected to the front edge of the main material strip via a distribution strip. The left side of this distribution strip is integrally widened to the left to form a widened left portion. The distance between the widened left portion and the soldering pin of the B7 terminal is less than the distance between the soldering pins of the B6 and B7 terminals. An extension strip extends integrally to the right from the right side of the distribution strip of the B6 terminal's soldering pin, and the rear edge of the extension strip maintains a distance from the front edge of the main material strip. The A8, A7, and A6 terminals are spaced from left to right along the front edge of the extended strip. When the extended strip is bent, the top surface of the right end of the extended strip overlaps the top surface of the left widening portion, so that the A6, A7, and A8 terminals are arranged from left to right. The soldering feet of the A6 and A7 terminals are located between the left side of the soldering foot of the B6 terminal and the right side of the soldering foot of the B7 terminal, and the soldering foot of the A8 terminal is located to the right of the soldering foot of the B6 terminal.

[0022] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves connecting an extension strip to the first terminal group on the front edge of the main material strip, and then connecting an extension strip to the front edge of the main material strip or the side of the first terminal group. The extension strip is connected to a second terminal group. By bending the extension strip, the second terminal group and the first terminal group are stacked vertically and with a gap. In this way, the upper and lower rows of terminals are cleverly combined into one, realizing the requirements of upper and lower rows of terminals on an integrated TYPE-C female terminal strip. This reduces the number of parts, reduces the difficulty of product production, and reduces production costs, which is conducive to the promotion and popularization of TYPE-C female connectors in small electronic products such as headphones.

Detailed Implementation

[0042] Please refer to Figures 1 to 17 As shown, it illustrates the specific structure of various embodiments of the present invention.

[0043] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] like Figures 1 to 10 As shown, it illustrates the specific structure of Embodiment 1.

[0045] An integrated TYPE-C female terminal strip includes a main strip 1 extending left and right and a first terminal group 2 connected to the front edge of the main strip 1. The first terminal group 2 includes two or more terminals arranged with a left-right spacing along the front edge of the main strip 1. An extension strip 3 is also connected to the front edge of the main strip 1 or the side of the first terminal group 2. The extension strip 3 is connected to a second terminal group 4, which is arranged side-by-side with the first terminal group 2. The second terminal group 4 includes two or more terminals arranged with a left-right spacing along the front edge of the main strip 1. A foldable area 301 is formed on the extension strip 3 between the second terminal group 4 and the first terminal group 2. The extension strip 3 is bent in the foldable area 301 so that the second terminal group 4 and the first terminal group 2 are stacked vertically and maintain a gap.

[0046] In this embodiment, the first terminal group 2 includes B6 terminal 201, B7 terminal 202, and B8 terminal 203 arranged from right to left (i.e., D+ terminal, D- terminal, and SBU2 terminal in sequence), and the second terminal group 4 includes A6 terminal 401, A7 terminal 402, and A8 terminal 403 arranged from right to left (i.e., D+ terminal, D- terminal, and SBU1 terminal in sequence). After the extension tape 3 is bent 180 degrees to the left and upward, the A6 terminal 401, A7 terminal 402, and A8 terminal 403 are arranged from left to right. This integrated TYPE-C female connector tape is mainly used, but not limited to, transmitting analog audio signals on headphones. The 6-pin Type-C female connector made using this integrated Type-C female connector strip can be used with standard 16-pin Type-C male connectors or standard 24-pin Type-C male connectors. Of course, if the standard 16-pin Type-C male connector or standard 24-pin Type-C male connector is also simplified in design, reducing the number of terminals and retaining only the necessary terminals, the 6-pin Type-C female connector made by this invention can also be used with the simplified Type-C male connector. Among them, terminals B6 201, B7 202, B8 203, A6 401, A7 402, and A8 403 can refer to the corresponding A6, A7, A8, B6, B7, and B8 terminals of a standard 24-pin Type-C female connector. For example, for a standard 24-pin Type-C female connector, its PIN definitions are as follows (from left to right, A1 to A12): GND, TX1+, TX1-, VBUS, CC1, D+, D-, SBU1, VBUS, RX2-, RX2+, GND; (from right to left, B1 to B12): GND, TX2+, TX2-, VBUS, CC2, D+, D-, SBU2, VBUS, RX1-, RX1+, GND. This utility model can be a simplified design based on the standard 24PINTYPE-C female connector. The A6\A7\A8\B6\B7\B8 mentioned in this utility model are defined the same as the A6\A7\A8\B6\B7\B8 of the standard 24PINTYPE-C female connector.Alternatively, terminals B6 201, B7 202, B8 203, and A6 401, A7 402, and A8 403 can refer to the corresponding A6, A7, A8, B6, B7, and B8 terminals of a standard 16-pin Type-C female connector. For example, the pin definitions of a standard 16-pin Type-C female connector are as follows (from left to right: A1, A4 to A9, A12): GND, TVBUS, CC1, D+, D-, SBU1, VBUS, GND; (from right to left: B1, B4 to B9, B12): GND, VBUS, CC2, D+, D-, SBU2, VBUS, GND. This invention is a simplified design based on the standard 16-pin Type-C female connector. The definitions of A6, A7, A8, B6, B7, and B8 mentioned in this invention are the same as those of the standard 16-pin Type-C female connector. The A6, A7, A8, B6, B7, and B8 pins of the TYPE-C female connector are the same; this is to meet the requirements of transmitting analog audio signals on headphones.

[0047] Furthermore, the rear end of the first terminal group 2 is connected to the main material strip 1, and the front end of the first terminal group 2 is connected to the first auxiliary material strip 5; the rear end of the second terminal group 4 is connected to the extension material strip 3, and the front end of the second terminal group 4 is connected to the second auxiliary material strip 6. The first auxiliary material strip 5 makes the first terminal group 2 a single unit, and the second auxiliary material strip 6 makes the second terminal group 4 a single unit, effectively forming the terminals in the same row into a single unit. This effectively improves the problem of poor alignment caused by the small cross-sectional area and long length of a single terminal during the stamping process.

[0048] Both the second auxiliary strip 6 and the first auxiliary strip 5 are provided with positioning holes E. After the extension strip 3 is bent, the positioning holes E of the two are aligned vertically. Furthermore, the side of the first auxiliary strip 5 is widened and designed with a positioning edge 51. After the extension strip 3 is bent, the positioning edge 51 is exposed on the outer periphery of the second auxiliary strip 6. Preferably, the second auxiliary strip 6 is stacked and adhered to the top surface of the first auxiliary strip 5, so that the vertical gap between the second auxiliary strip 6 and the first auxiliary strip 5 is zero. Thus, the rear end faces of the second auxiliary strip 6 and the first auxiliary strip 5 together form a sealing surface C1. During injection molding, this can seal the front end of the tongue of the insulating body 200, preventing overflow and burrs at the front end during the injection molding process, which would affect product quality.

[0049] Typically, each terminal of the first terminal group 2 includes, from back to front, a first welding pin F1, a first fixing part F2, a first contact part F3, and a first front extension part F4. The first welding pin F1 extends horizontally, the first fixing part F2 extends integrally upward from the front end of the first welding pin F1, the first contact part F3 extends integrally forward from the upper end of the first fixing part F2, and the first front extension part F4 extends integrally forward from the front end of the first contact part F3 and is connected to the first auxiliary material strip 5. Each terminal of the second terminal group 4 includes, from back to front, a second welding pin G1, a second fixing part G2, a second contact part G3, and a second front extension part G4. The second welding pin G1 extends horizontally... The second fixing part G2 extends integrally downward from the front end of the second welding foot G1, the second contact part G3 extends integrally forward from the lower end of the second fixing part G2, and the second front extension part G4 extends integrally forward from the front end of the second contact part G3 and connects to the second auxiliary material strip 6. After the extension material strip 3 is bent, the first welding foot F1 and the second welding foot G1 are arranged side by side with a spacing between them, the first fixing part F2 and the second fixing part G2 are arranged side by side with a spacing between them, the second contact part G3 is located above the first contact part F3 and maintains a spacing, the second auxiliary material strip 6 is stacked on top of the first auxiliary material strip 5, and the second front extension part G4 and the first front extension part F4 are arranged with a spacing between them. In this way, the problem of collision between the second terminal group and the first terminal group is avoided when bending.

[0050] Furthermore, the first front-end extension F4 includes a first horizontal extension body F41 and a first bending part F42. The first bending part F42 extends forward and obliquely upward from the front end of the first contact part F3 (forming a Z-shaped bend), that is, the rear end of the first bending part F42 is integrally connected to the front end of the first contact part F3. The first horizontal extension body F41 is connected to the front end of the first bending part F42, making the first horizontal extension body F41 higher than the first contact part F3. The rear section of the first horizontal extension body F41 has a thinned top design, as shown in the figure, the thinned part F401. The front end of the first horizontal extension body F41 is connected to the first auxiliary strip 5. The second front-end extension G4 includes a second horizontal extension body G41 and a second bending part G42. The second bending part G42 extends forward and obliquely upward from the front end of the second contact part G3 (forming a Z-shaped bend), that is, the second bending part G42... The rear end of the first horizontal extension body G41 is integrally connected to the front end of the second contact part G3. The second horizontal extension body G41 is connected to the front end of the second bending part G42, so that the second horizontal extension body G41 is higher than the second contact part G3. The top of the rear section of the second horizontal extension body G41 is thinned, as shown in the figure, the thinned part G401. The front end of the second horizontal extension body G41 is connected to the second auxiliary strip 6. After the extension strip 3 is bent, the second horizontal extension body G41 is lower than the second contact part G3. The top of the thinned part of the rear section of the second horizontal extension body G41 is set downward, so that the vertical gap D1 between the rear sections 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 sufficient gap at this point to prevent short circuit between the upper and lower rows of terminals (since the first bending part F42 and the second bending part G42 are not completely staggered, if the vertical gap is insufficient, it may cause a short circuit problem between the upper and lower rows of terminals). Furthermore, 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 as a bent and recessed type (the heads of the upper and lower rows of terminals face each other, which is equivalent to the design of the middle of the tongue near the insulating body). The vertical distance between the first contact portion F3 and the second contact portion G3 is relatively large, while the distance between the first bending portion F42 and the second bending portion G42 gradually decreases until the distance between the first horizontal extension body F41 and the second horizontal extension body G41 is even smaller. By having the first bending portion F42, the second bending portion G42, the first horizontal extension body F41, and the second horizontal extension body G41 recessed into the tongue portion of the insulating body, the phenomenon of pin lifting at the terminal head can be effectively prevented. Even after repeated insertion and removal, the phenomenon of pin lifting will not occur.

[0051] The extension strip 3 is bent upwards and to the left by 180 ± 5 degrees. Before bending, the horizontal height of the soldering feet of each terminal of the first terminal group 2 is slightly higher than the horizontal height of the soldering feet of each terminal of the second terminal group 4. Thus, when the extension strip 3 is bent upwards by 180 degrees, the horizontal height of the soldering feet of each terminal of the second terminal group 4 becomes higher, so that it is level with the horizontal height of the soldering feet of each terminal of the first terminal group 2. In this way, after folding, there are two sets of terminal groups arranged in upper and lower rows, and all their soldering feet are at the same horizontal height, which facilitates the soldering of connectors to components such as PCB boards.

[0052] The first horizontal extension body F41 of the B6 terminal 201 is offset to the right from the front end of its first contact portion F3 to increase the lateral distance 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 is offset to the right from the front end of its first contact portion F3 to increase the lateral distance 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; and after the extension strip 3 is bent, the second horizontal extension body F41 of the A6 terminal 401... The extension body G41 is located between the left and right distances of 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 and right distances of the first horizontal extension body F41 of the B7 terminal 202 and the first horizontal extension body F41 of the B6 terminal 201. The first horizontal extension body F41 of the B6 terminal 201 is located between the left and right distances of 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 portion G3 of the upper row A6 / A7 terminals and the first contact portion F3 of the lower row B7 / B6 terminals are directly opposite each other (i.e., they overlap horizontally), there are no supporting parts in the mold during the insert molding process, which leads to a short circuit risk between the upper and lower rows of terminals. In this embodiment, the first horizontal extension body F41 and the second horizontal extension body G41 are deliberately arranged side by side (i.e., staggered horizontally) to facilitate the addition of supporting parts in the mold to support and position the first horizontal extension body F41 and the second horizontal extension body G41, thereby avoiding the risk of short circuit between the upper and lower rows of terminals.

[0053] 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 13As 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 the right end of the extension strip 3 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 feet of terminals A6 401 and A7 402 are located between the left side of the soldering foot of terminal B6 201 and the right side of the soldering foot of terminal B7 202, and the soldering foot of terminal A8 403 is located to the right of the soldering foot of terminal B6 201.

[0054] like Figures 11 to 14 As shown, it illustrates the specific structure of Embodiment 2.

[0055] Example 2 is structurally similar to Example 1, with the main difference being: In Example 2, a third bending portion F43 (forming a Z-shaped bend) is integrally connected between the front end of the first horizontally extending body F41 and the first auxiliary material strip 5, and a fourth bending portion G43 (forming a Z-shaped bend) is integrally connected between the front end of the second horizontally extending body G41 and the second auxiliary material strip 6. The design of the third bending portion F43 and the fourth bending portion G43 ensures that the first auxiliary material strip 5 and the second auxiliary material strip 6 overlap and fit tightly after bending, forming an effective sealing structure. In Example 2, before bending, the extension material strip 3 of the integrated TYPE-C female terminal strip undergoes two bending designs from the first contact portion F3 to the first auxiliary material strip 5: a first bending portion F42 and a third bending portion F43. This results in the first horizontally extending body F41 being slightly higher than the first contact portion F3, and the first auxiliary material strip 5 being slightly higher than the first horizontally extending body F41. Similarly, before bending, the extension strip 3 of the integrated TYPE-C female terminal strip undergoes two bending designs from the second contact portion G3 to the second auxiliary strip 6, namely: the second bending portion G42 and the fourth bending portion G43. This makes the horizontal height of the second horizontal extension body G41 slightly higher than the horizontal height of the second contact portion G3, and the horizontal height of the second auxiliary strip 6 slightly higher than the horizontal height of the second horizontal extension body G41. When the extension strip 3 of the integrated TYPE-C female terminal strip is bent at 180± After 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 auxiliary strip 6 is slightly lower than the horizontal height of the second horizontal extension body G41. This creates a situation where the heads of the upper and lower rows of terminals gradually approach each other, and 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. The first auxiliary strip 5 and the second auxiliary strip 6 are tightly fitted (vertical distance is zero). Furthermore, given the addition of the third bend F43 and the fourth bend G43, since the vertical distance between the first horizontal extension body F41 and the second horizontal extension body G41 is sufficient to prevent short circuits between the upper and lower rows of terminals, the thinning design at the top of the rear section of the first horizontal extension body F41 is optional, and the thinning design at the bottom of the rear section of the second horizontal extension body G41 is optional, or only one side of the opposing surfaces can be thinned.

[0056] like Figure 15 As shown, it illustrates the specific structure of Embodiment 3.

[0057] The structure of Example 3 is basically the same as that of Example 1. The main difference is that in Example 3, the extension strip 3 is directly connected to the front edge of the main strip 1.

[0058] like Figure 16 As shown, it illustrates the specific structure of Embodiment 4.

[0059] The structure of Example 4 is basically the same as that of Example 1. The main difference is that in Example 4, terminals B6, B7, and B8 are connected to the front end of the same material distribution strip. The material distribution strip extends forward from the front end of the main material strip 1. The welding feet of terminals B6, B7, and B8 are connected to the front edge of the material distribution strip at left and right intervals, respectively. The extension strip 3 extends to the right from the right side of the material distribution strip.

[0060] like Figure 17 As shown, the integrated TYPE-C female terminal strip of Embodiment 1 is formed into an insulating body 200 by insert molding after its extension strip 3 is bent by 180±5 degrees. The slit line L is located at the rear end of the soldering pin of each terminal and in front of the extension strip 3. Therefore, the connection structure between the rear end of the soldering pin of each terminal of the first terminal group 2 and the main strip 1 can be flexibly designed as needed and is not limited to Embodiment 1. It can also be designed in other ways, such as Embodiment 3, Embodiment 4 or other different situations.

[0061] The key design feature of this invention is that it connects an extension strip to the front edge of the main material strip or the side of the first terminal group, and then connects the extension strip to a second terminal group. By bending the extension strip, the second terminal group and the first terminal group are stacked vertically and with a gap maintained. In this way, the upper and lower rows of terminals are cleverly combined into one, realizing the requirements of upper and lower rows of terminals on an integrated TYPE-C female connector terminal strip. This reduces the number of parts, lowers the difficulty of product manufacturing, and reduces production costs, which is conducive to the promotion and popularization of TYPE-C female connectors in small electronic products such as headphones.

[0062] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
