Description

TECHNICAL FIELD

[0001] The utility model relates to TYPE-C fast charging female head field technology especially is TYPE-C 12PIN female head terminal group, TYPE-C fast charging female head and electronic product. BACKGROUND

[0002] With the popularization of TYPE-C connector, it is very common to use TYPE-C interface to facilitate the charging of electronic equipment, according to the USB association, the standard TYPE-C female head needs 24PIN terminal, which contains charging terminal, data transmission terminal and the like, the terminal quantity is much, the adjacent terminal is dense, the spacing is small, and the manufacturing process is complex.

[0003] Therefore, the industry improves and designs some simple TYPE-C connectors according to the use demand of TYPE-C connectors only for charging function without data transmission function (power socket, automobile, power bank, wireless earphone and the like), which mainly reduces the terminal quantity, for example: CN 209344410 U discloses a simple TYPE-C connector scheme, which has standard 8 PIN (4 PIN GND terminal and 4 PIN VBUS terminal) charging terminal and 2PIN CC terminal, can support fast charging protocol, but, but it does not conform to the latest version of the association standard, for example: without A6 / A7 / B6 / B7 PIN terminal, and the association standard defines that the 4 PIN terminal has no soldering leg, A6 / A7 is short-circuited, and B6 / B7 is short-circuited.

[0004] Furthermore, in existing simplified Type-C connector designs, the terminal module is arranged in two rows within an insulating body. The terminal module includes the first PIN (A1), second PIN (A4), third PIN (A5), fourth PIN (A9), and fifth PIN (A12) in the upper row, and the sixth PIN (B12), seventh PIN (B9), eighth PIN (B5), ninth PIN (B4), and tenth PIN (B1) in the lower row. The first PIN (A1) and sixth PIN (B12) are soldered to a single pad on the PCB; the second PIN (A4) and seventh PIN (B9) are soldered to a single pad on the PCB. The first pad is on the PCB; the third pin (A5) is soldered to a single pad on the PCB; the eighth pin (B5) is soldered to a single pad on the PCB; the fourth pin (A9) and the ninth pin (B4) are soldered to a single pad on the PCB; the fifth pin (A12) and the tenth pin (B1) are soldered to a single pad on the PCB. The terminal structure is not simplified enough, with a large number of soldering pins, making soldering cumbersome. Furthermore, soldering smaller pins makes it difficult to further control process yield. Additionally, the arrangement of multiple terminals in the upper and lower rows is limited by connector standard dimensions, resulting in smaller terminal sizes that cannot meet the requirements for higher current transmission.

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

[0071] In this embodiment, the first GND terminal 10, the first VBUS terminal 20, the first CC terminal 50, the second CC terminal 60, the second VBUS terminal 30, and the second GND terminal 40 are an integrated terminal group. The first CC terminal 50 and the second CC terminal 60 are connected to the second D+ terminal 70 and the second D- terminal 80 through the auxiliary material strip 1”. That is, these terminals are connected together on one side of the same side material strip 1’. The six welding feet are arranged side by side and connected to the same side of the side material strip 1’. The structure is simple. This integrated terminal material strip 1 is suitable for continuous stamping production. Compared with the two-row terminal group, the integrated terminal material strip 1 design in this embodiment makes the terminal position accuracy controllable better.

[0072] In this embodiment, the first vertical plate portion 102 is formed by bending the left side of the first horizontal plate portion 101 upwards, the second vertical plate portion 202 is formed by bending the left side of the second horizontal plate portion 201 upwards, the third vertical plate portion 302 is formed by bending the right side of the third horizontal plate portion 301 upwards, and the fourth vertical plate portion 402 is formed by bending the right side of the fourth horizontal plate portion 401 upwards. This allows the first horizontal plate portion 101, the second horizontal plate portion 201, the third horizontal plate portion 301, and the fourth horizontal plate portion 401 to be designed with larger width dimensions. In addition to meeting the requirement of transmitting larger currents, this also helps the terminal group to be more stably positioned within the insulation body. In other embodiments, the first vertical plate portion is bent upwards or downwards from one side of the first horizontal plate portion, the second vertical plate portion is bent upwards or downwards from one side of the second horizontal plate portion, the third vertical plate portion is bent upwards or downwards from one side of the third horizontal plate portion, and the fourth vertical plate portion is bent upwards or downwards from one side of the fourth horizontal plate portion. The top and bottom of the vertical plate portions of the same terminal are used as the upper and lower rows of contacts for the corresponding terminals, thus realizing an 8-pin current transmission terminal contact portion for the TYPE-C standard provided by a 4-pin terminal. Compatible with the USB fast charging protocol, this connector features a simple and ingenious structure, facilitating integrated terminal block design and easy manufacturing. It replaces the traditional top and bottom terminal block design, reducing the number of soldering pins and simplifying the process. The female terminal block's positioning accuracy within the insulating body is improved, enhancing process efficiency and yield, and effectively reducing costs. With the traditional 8-pin terminal block replaced by a 4-pin terminal block, each pin has a larger design size, allowing for the design of larger terminals as needed. The increased cross-sectional area of ​​the contact area meets higher current transmission requirements, further improving fast charging performance. Furthermore, the improved structural strength of the terminal block enhances the overall structural strength, durability, and reliability of the tongue and the Type-C fast charging female connector, making it less susceptible to damage from charging, plugging / unplugging, or impacts. (Comparison) Figure 11 and Figure 12As shown, if the first GND upper row contact portion 12 and the second GND upper row contact portion 42 are designed as upper and lower rows with spacing, the area of ​​their terminal local cross-section is significantly smaller than the area of ​​the terminal local cross-section when the first GND upper row contact portion 12 and the second GND upper row contact portion 42 are formed at the top and bottom of the first vertical plate portion 102, respectively. In other words, by adopting a vertical plate structure, that is, by using the arrangement of the first vertical plate portion 102, the second vertical plate portion 202, the third vertical plate portion 302, and the fourth vertical plate portion 402, the function of one terminal carrying two contact portions can be realized. For this PIN terminal, the cross-sectional area of ​​its contact portion, the cross-sectional area of ​​its fixing portion, and the cross-sectional area of ​​its soldering feet can all be designed to be large, meeting the requirements of high current transmission.

[0073] Since the first vertical plate 102, the second vertical plate 202, the third vertical plate 302, and the fourth vertical plate 402 are all formed by stamping and bending on metal sheets, it is very easy to stamp out the positioning groove C1, the locking point C2, and design the top and bottom shapes and dimensions of the first vertical plate 102, the second vertical plate 202, the third vertical plate 302, and the fourth vertical plate 402. Furthermore, the bent first vertical plate 102, the second vertical plate 202, the third vertical plate 302, and the fourth vertical plate 402 result in better overall structural strength of the TYPE-C12PIN female terminal block 100, further improving the connector's insertion and extraction resistance and preventing tongue breakage.

[0074] In this embodiment, the metal spacer 400 with 2-pin terminals and the TYPE-C 12-pin female terminal block 100 are injection molded together and fixed inside the insulating body 200. Specifically, a positioning groove C1 is provided at the front end of the first GND terminal 10 and the second GND terminal 40. The metal spacer 400 with 2-pin terminals is inserted into the positioning groove C1 to form contact positioning with the corresponding first GND terminal 10 and second GND terminal 40. The metal spacer 400 with 2-pin terminals includes a left partition portion 410 and a right partition portion 420 with a symmetrical design (the first GND terminal 10 and the second GND terminal 40 are also symmetrical to each other). The side partition portion 420 is engaged in the corresponding positioning groove C1; and the first GND terminal 10 and the second GND terminal 40 are provided with locking points C2 to prevent the metal spacer 400 with the 2-pin terminal from dislodging forward, and the left partition portion 410 and the right partition portion 420 are restricted by the rear end of the corresponding locking point C2; wherein, the left partition portion 410 and the right partition portion 420 are connected as one unit by a rear connecting arm 430, and the rear ends of the A6 contact portion (D+) and the A7 contact portion (D-) are integrally connected to the front end of the rear connecting arm 430. The front ends of the A6 contact portion and the A7 contact portion are generally connected as one unit by a horizontal plate portion, forming a U-shaped structure.Contacts A6 and A7 are shorted together, and neither contact has a soldered pin. Contacts B6 and B7 are also shorted together, and neither contact has a soldered pin. This conforms to the latest USB standard for Type-C (e.g., USB Type-C 2.4 specification). The simplified product requires only 6 soldered pins for the 14-pin terminal. This facilitates the production of the metal spacer 400 with the 2-pin terminal, and allows the metal spacer 400 with the 2-pin terminal to be inserted into the Type-C connector in one step. On the 12PIN female terminal block 100; the left partition portion 410 and the right partition portion 420 each include a horizontal base plate portion 4001, a rear end folding plate portion 4002, and a C-shaped bending portion 4003; the horizontal base plate portion 4001 has a slot C3 extending forward and backward, the lower end of the rear end folding plate portion 4002 is integrally connected to the rear end of the horizontal base plate portion 4001, and is bent upward and extended, so that the upper end of the rear end folding plate portion 4002 is higher than the horizontal base plate portion 4001; the C-shaped bending portion 4003 includes an integrally connected top wall 4031, an outer side wall 4032, and a bottom wall 4033, the upper and lower ends of the outer side wall 4032 are respectively connected to the outer ends of the top wall 4031 and the bottom wall 4033, thus forming a C-shaped structure, the left partition portion 410 and the right partition portion 420 each include a horizontal base plate portion 4001, a rear end folding plate portion 4002, and a C-shaped bending portion 4003; the horizontal base plate portion 4001 has a slot C3 extending forward and backward, the lower end of the left partition portion 410 and the right partition portion 420 are integrally connected to the rear end of the horizontal base plate portion 4001, and the rear end folding plate portion 4002 is bent upward and extended upward, so that the upper end of the rear end folding plate portion 4002 is higher than the horizontal base plate portion 4001; the C-shaped bending portion 4003 includes a top wall 4031, an outer side wall 4032, and a bottom wall 4033, the upper and lower ends of the outer side wall 4032 are respectively connected to the outer ends of the top wall 4031 and the bottom wall 4 The C-shaped bends 4003 of the plate portion 420 are all designed to open inwards. Considering the smoothness of assembly, a guide portion 4034 extending obliquely downwards can also be connected to the rear end of the bottom wall 4033. The structural design of the left partition portion 410 and the right partition portion 420 effectively strengthens the structural strength of the tongue piece 2001. The front end of the top wall 4031 is connected to the upper end of the rear end folding plate portion 4002. The slot C3 extends backwards through the rear end of the horizontal base plate portion 4001 and the rear end folding plate portion 4002 until it extends to the top wall 4031 (for example, about 1 / 3 to 1 / 2 of the way). In this way, the internal rear end surface formed by the slot C3 on the top wall 4031 and the rear end surface of the locking point C2 can be mutually restrained to prevent the metal middle partition piece 400 with 2-pin terminals from coming out forward. The left partition 410 and the right partition 420 are connected as one unit by a rear connecting arm. The metal middle partition 400 with 2-pin terminals is inserted into the TYPE-C 12-pin female terminal group in one go. The first vertical plate 102 and the fourth vertical plate 402 are connected by the left partition 410, the right partition 420 and the rear connecting arm to form an integrated U-shaped frame structure, which further strengthens the structural strength of the tongue.

[0075] The assembly process of the TYPE-C 14PIN fast charging female connector described in this embodiment is detailed below:

[0076] First, prepare a TYPE-C 12PIN female terminal block 100 and a metal spacer 400 with 2PIN terminals. The TYPE-C 12PIN female terminal block 100 is linearly conveyed on a continuous stamping production strip. At the insertion station, the metal spacer 400 with 2PIN terminals is inserted into the TYPE-C 12PIN female terminal block 100 from front to back. During the relative front-to-back displacement of the 12PIN female terminal block 100 and the metal spacer 400 with 2PIN terminals, the first vertical plate 102 and the fourth vertical plate 402 pass through the corresponding C-shaped bend 4003 and the slot C3 until the positioning slot C1 is engaged with the inner front end face of the slot C3, the locking point C2 is engaged in the slot C3 and limited to the inner rear end face of the slot C3, the bottom surface of the top wall 4031 is limited to the top surface of the corresponding first vertical plate 102 or the second vertical plate 202, and the top surface of the bottom wall 4033 is limited to the bottom surface of the corresponding first horizontal plate 101 or the second horizontal plate 201. At this point, the metal spacer 400 with 2PIN terminals and the TYPE-C 12PIN female terminal block 100 are reliably assembled and positioned in the left-right direction, front-to-back direction and up-down direction, and the metal spacer 400 with 2PIN terminals forms a firm connection with the first GND terminal 10 and the second GND terminal 40.

[0077] Then, the assembled TYPE-C 12PIN female terminal block 100 and the metal spacer 400 with 2PIN terminals are injection molded together (also referred to as embedded injection molding), so that the TYPE-C 12PIN female terminal block 100 and the metal spacer 400 with 2PIN terminals are embedded in the insulating body 200; the vertical extension height of the first vertical plate 102, the second vertical plate 202, the third vertical plate 302, and the fourth vertical plate 402 respectively penetrates the top and bottom surfaces of the tongue;

[0078] Then remove the auxiliary material strip 1” and the edge material strip 1’ (generally, the auxiliary material strip 1” is removed first, and then the edge material strip 1’ is removed, also known as the main material strip); to obtain a single TYPE-C fast charging female head body (the TYPE-C fast charging female head body includes an insulating body 200 and a TYPE-C 12PIN female head terminal group 100 and a metal spacer 400 with 2PIN terminals disposed on the insulating body 200);

[0079] Then, the individual TYPE-C fast charging female connector body is inserted into the prepared housing 300. For example, the TYPE-C fast charging female connector body is inserted into the housing 300 from back to front. The pre-set spring clips on the housing 300 engage with the corresponding recesses on the insulating body 200, achieving mutual assembly and positioning of the TYPE-C fast charging female connector body and the housing 300. The six soldering pins are exposed at the bottom rear end of the housing 300.

[0080] An electronic product is provided, comprising an electronic product body, wherein the electronic product body is provided with a TYPE-C 14PIN fast charging female connector conforming to the association specifications as described in any of the preceding claims. This TYPE-C 14PIN fast charging female connector, conforming to association standards, can be widely used in power sockets, charging adapters, power banks (also referring to portable storage devices or portable chargers), headphone charging cases, wireless headphones, car charging devices, table lamps, fans, phone holders, electric shavers, electric toys, and other electronic products requiring charging interfaces. It achieves high-current fast charging (usually without data transmission) at a relatively low cost. This TYPE-C 14PIN fast charging female connector, capable of meeting high current requirements, has a simple and reliable structure, is durable, and has a long lifespan. It is not easily damaged by electronic products during charging, plugging / unplugging, or collisions, thus avoiding negative impacts on user experience and preventing increased product failure rates, repair rates, or even complete product scrapping due to connector malfunction. Therefore, using this high-current TYPE-C 14PIN fast charging female connector on electronic products improves user experience and reduces after-sales service costs.

[0081] The key design feature of this invention lies in the arrangement of the first GND terminal, first VBUS terminal, first CC terminal, second CC terminal, second VBUS terminal, and second GND terminal. Only six soldering pins are needed to integrate contacts A1, A4, A5, A9, A12, B1, B4, B5, B6, B7, B9, and B12 onto a single terminal assembly. These six soldering pins are connected to the same main material strip. The front ends of contacts A5 and B5 serve as connecting ends to the secondary material strip, which then connects to contacts B6 and B7, forming a short circuit. This meets the fast charging requirements of the latest USB standard for Type-C. Reducing the number of soldering pins simplifies the soldering process, improves process efficiency and yield, effectively reduces costs, and allows for larger terminal sizes to meet higher current transmission requirements.

[0082] This type of TYPE-C 12PIN female connector terminal set is used in TYPE-C fast charging female connectors. Because the terminal set can be used as an integrated terminal strip, it is easy to install (or injection molded and fixed) onto the insulating body. Furthermore, by providing a metal partition with 2PIN terminals, the left and right partition portions of the metal partition are connected as a single unit by a rear connecting arm. The rear connecting arm extends forward integrally and provides A6 and A7 contacts, which form a short circuit. The metal partition with 2PIN terminals and the TYPE-C 12PIN female connector terminal set are assembled to form a terminal partition assembly. The left and right partition portions are in contact with the first and second GND terminals, respectively. An insulating body is injection molded onto the terminal partition assembly. The 14PIN terminal contact points require only 6 soldering pins. With a simpler and more reliable structure and process, and at a lower cost, it meets the fast charging requirements of the latest USB standard for TYPE-C.

[0083] 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.
