Description

Technical Field

[0001] This invention relates to the field of electronic accessories technology, and in particular to an anti-static Type-C female connector and its connector. Background Technology

[0002] Many electronic devices now have Type-C USB4 data communication interfaces, such as high-end laptops, servers, high-end cameras, high-speed external hard drives, and mobile graphics cards. However, because many products lack anti-static design and corresponding measures, users may experience high-speed data transmission but also face the risk of the device being damaged by static electricity. Summary of the Invention

[0003] The purpose of this invention is to provide an anti-static Type-C female connector and its connector. Compared with the commonly used method of soldering Type-C female connectors to PCB boards, this direct connection method eliminates the need for soldering and minimizes impedance changes, echo crosstalk, and overall attenuation caused by soldering and the soldering process, thus fully ensuring signal transmission speed and signal integrity. At the same time, the TVS diode soldered on the PCB board for ESD protection of high-speed signals can effectively prevent connected devices from being damaged by electrostatic discharge.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anti-static Type-C female connector, comprising: an integrated female connector circuit board, an inner support member of the circuit board, and a metal shielding shell surrounding the integrated female connector circuit board and the inner support member to form a Type-C female connector interface. The integrated female connector circuit board has standard gold fingers in the horizontal direction as standard female connector terminals. An inner support member extends vertically from the integrated female connector circuit board. The metal shielding shell is sleeved on the inner support member, limiting and forming the corresponding Type-C female connector interface.

[0005] The preferred embodiment is that the integrated circuit board of the female connector and the internal support component of the circuit board are integrally injection molded or produced separately, and the internal support component of the circuit board is connected to the integrated circuit board of the female connector in the vertical direction by means of sleeve, adhesive or snap-fit ​​assembly.

[0006] The preferred embodiment is that the thickness of the integrated circuit board of the female connector, as well as the setting position and size of the gold fingers, are the same as the corresponding connector of the standard Type-C female connector.

[0007] The preferred embodiment is as follows: the support component inside the circuit board is provided with a limiting groove, which abuts against the protrusion of the metal shielding shell of the female connector to limit the connection, forming a Type-C female connector interface.

[0008] The preferred embodiment is that the integrated circuit board of the female connector has edge-hardening protrusions on both sides.

[0009] The preferred embodiment is that the top of the VBUS gold finger of the integrated circuit board of the female connector is provided with a via for connection and is covered with solder resist.

[0010] The preferred embodiment is that the high-speed data line of the integrated circuit board of the female connector is connected to a TVS electrostatic protection tube.

[0011] The preferred embodiment is that the first end face of the metal shielding shell of the female connector is provided with a clearance notch on both the left and right sides, and the clearance notch corresponds to the grounding point of the integrated circuit board of the female connector.

[0012] The preferred embodiment is as follows: the second end face of the female metal shielding shell has an outer edge of the metal shielding shell, and a protective sleeve connecting the metal shielding shell is fitted onto the female metal shielding shell and abuts against the outer edge of the metal shielding shell. Several spring pieces extend inward from the upper and lower end faces of the female metal shielding shell near the insertion interface.

[0013] The preferred embodiment further includes an anti-static Type-C connector, comprising a Type-C female connector, and the circuit is connected to the circuit pins of the Type-C male connector A through an electrical connection terminal at the other end of the integrated circuit board of the female connector, with the metal shielding overlapped with the metal shell of the Type-C male connector A.

[0014] The preferred embodiment is that the Type-C male connector A is a solderless male connector or a solderable Type-C male connector.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) This invention directly fits the female connector's metal shielding shell onto the outside of the integrated circuit board and the supporting components within the circuit board, forming a Type-C female connector interface. The printed gold fingers on the integrated circuit board directly serve as the connection components for the standard Type-C female connector. Compared to the commonly used method of soldering the Type-C female connector to the PCB board, this direct, solder-free connection minimizes impedance changes, echo crosstalk, and overall attenuation caused by soldering and the soldering process, thus fully ensuring signal transmission speed and signal integrity. The TVS diode soldered on the PCB board for ESD protection of high-speed signals effectively prevents connected devices from suffering electrostatic damage.

[0017] (2) The present invention forms a Type-C female connector by simply attaching a metal shielding shell to the outside of the integrated circuit board and the support component inside the circuit board, and the metal shielding shell is connected to the protective sleeve and the outer shell. The assembly process is simpler, which not only reduces the difficulty and cost of production process, but also further reduces the performance risk caused by improper welding of electrical connection components.

[0036] With the continuous development of information transmission technology, the requirements for information transmission speed are getting higher and higher, which in turn puts higher and higher demands on the performance of information transmission connectors. Not only are better materials and higher precision required, but also more stringent process assurance. Connectors are widely used in various fields as power or data transmission converters, and the connectors commonly seen in daily life have evolved from USB-A and Micro USB to USB-C (Type-C). Type-C connectors have not only greatly improved the speed of power transmission and data transmission, but also improved the asymmetry problem between USB-A connectors and Micro USB connectors.

[0037] However, although the Type-C female connector has the aforementioned symmetrical characteristics and is flat and round, its size and shape cannot be changed under international standards. During repeated insertion and insertion of existing Type-C male connectors and Type-C female connectors, static electricity is often generated, which poses a risk of damage to the device when users experience high-speed data transmission through the Type-C connector.

[0038] In view of this, the creator has devoted himself to researching and applying theoretical principles to address the shortcomings of the existing technology, and has made every effort to solve the aforementioned problems, which is the purpose of the creator's improvement.

[0039] The main purpose of this invention is to effectively avoid the risk of electrostatic discharge (ESD) damage to the device by matching and combining the integrated circuit board and the supporting components inside the circuit board to form a Type-C female connector.

[0040] The detailed description and technical content of this invention will be explained below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of Embodiment 1 of this invention.

[0041] This invention provides an anti-static Type-C female connector B, which can effectively avoid the generation of static electricity during repeated plugging and connection, and protect connected devices from the risk of static damage.

[0042] Please refer to Figure 2 and Figure 3 As shown, the anti-static Type-C female connector B of this invention includes a female connector integrated circuit board 11, a female connector metal shielding shell 12, a circuit board inner support 13, a metal shielding shell connecting protective sleeve 14, and an outer shell 15. The female connector metal shielding shell 12 is sleeved on the outside of the female connector integrated circuit board 11 and the circuit board inner support 13 to form a Type-C female connector interface 123.

[0043] In this implementation, such as Figure 7As shown: The circuit board inner support 13 is made of an insulating material such as plastic, but this invention does not impose many limitations on this. In this embodiment, the circuit board inner support 13 is sleeved on the vertical direction of the female integrated circuit board 11, but this invention is not limited to this. For example, the circuit board inner support 13 can also be an integral component with the female integrated circuit board 11 or a two-piece component that is fixed together in other forms. The female integrated circuit board 11 and the circuit board inner support 13 can be integrally injection molded, or the circuit board inner support 13 can be produced separately and then connected to the female integrated circuit board by bonding, snap-fitting or other assembly methods. The upper and lower end faces of the circuit board inner support 13 have a number of limiting grooves 131, which abut against and limit the metal shielding shell abutment protrusions 125 on the inner surface of the female metal shielding shell 12. In this embodiment, the limiting groove 131 is formed on the upper and lower end faces of the support member 13 inside the circuit board. However, in other embodiments, it can also be formed on the bottom or side of the support member 13 inside the circuit board, as long as it corresponds to the limiting point 125 of the metal shielding shell of the female metal shielding shell 12.

[0044] In this embodiment, the Type-C male connector A can be either the solderless male connector shown in this invention or a solderable Type-C male connector.

[0045] like Figure 7 As shown: The thickness of the integrated circuit board 11 of the female connector and the position and size of the gold fingers 111 are the same as the corresponding connector of the standard Type-C female connector. Since USB Type-C has clear specifications for its interface, size and pin arrangement, and these are not the main technical focus of this work, they are omitted here and will not be described in detail.

[0046] In this embodiment, the gold fingers 111 printed on the integrated circuit board 11 of the female connector are directly used as the plug-in components of the standard Type-C female connector, which not only reduces the difficulty and cost of the production process, but also further reduces the performance risk caused by improper soldering of electrical connection components.

[0047] Furthermore, due to the varying performance of Type-C female connectors from different manufacturers, even high-performance Type-C female connectors can experience performance degradation due to improper soldering. Specifically, if the Type-C female connector is not protected against soldering temperature during surface mount soldering, the plastic structure may deform due to heat during reflow soldering, resulting in changes in electrical performance parameters. Even with soldering temperature protection, improper pad design can still generate signal vortices, affecting IMR (Integrated Multic Reflection) and IRL (Integrated Return Loss), which in turn affects ILfit@Nq (attenuation index), significantly reducing signal transmission speed and increasing the likelihood of signal errors. In this embodiment, the gold fingers 111 of the integrated circuit board 11 are directly used as standard Type-C female connectors. This eliminates the need for soldering and allows for a direct, through-connection, minimizing impedance abrupt changes. This ensures excellent performance in IMR (Integrated Multic Reflection), IRL (Integrated Return Loss), and ILfit@Nq (attenuation index), further guaranteeing signal transmission speed and integrity. A reasonable distance exists between the gold fingers 111 to prevent multiple gold fingers 111 from conducting during use. Furthermore, the ends of the gold fingers 111 are covered with solder resist, which also provides some restraint, preventing misalignment during prolonged insertion and removal.

[0048] like Figure 1 As shown: In this embodiment, the terminals can be arranged as follows: the first ground terminal GND is located at terminal A1, the transmitting terminal TX1+ is located at terminal A2, the transmitting terminal TX1- is located at terminal A3, the first power terminal VBUS is located at terminal A4, the first USB PD communication line terminal CC1 is located at terminal A5, the first data terminal D+ is located at terminal A6, the second data terminal D- is located at terminal A7, the first auxiliary terminal SBU1 is located at terminal A8, the second power terminal VBUS is located at terminal A9, the receiving terminal RX2- is located at terminal A10, the receiving terminal RX2+ is located at terminal A11, and the second ground terminal GND is located at terminal A12. Of course, this is only one possible arrangement for the gold finger 111, and different arrangements can be made according to the function.

[0049] In this embodiment, the integrated circuit board 11 of the female connector is provided with edge-hardening protrusions 112 on both sides. The existing Type-C female connector is provided with metal plates on both sides, the purpose of which is to generate a certain resistance and form a certain insertion and extraction force when the male and female connectors are inserted. In this embodiment, the purpose of edge-hardening on both sides of the integrated circuit board 11 of the female connector is to not only provide a certain insertion and extraction force when it is inserted with the male connector, but also to have wear resistance.

[0050] Furthermore, in this embodiment, the integrated circuit board 11 of the female connector uses etching and adhesive bonding to attach eight functional gold fingers 111. These functional gold fingers 111 include VBUS gold fingers 1111 for power supply and gold fingers for signal transmission. The top of each VBUS gold finger 1111 is connected via a via 1112 and covered with solder resist. The VBUS gold fingers 1111 are connected to the power supply and generate significant heat during operation. Since the VBUS gold fingers 1111 are connected to the circuit board substrate via etching and adhesive bonding, they are subject to considerable heat and frequent insertion and removal, making them prone to detachment. Connecting the top of each VBUS gold finger 1111 via the via 1112 provides reinforcement. The other signal gold fingers, due to the very small current they carry, generate negligible heat and require no special design.

[0051] Furthermore, in this embodiment, all eight high-speed data lines of the integrated circuit board 11 are equipped with TVS electrostatic discharge (ESD) protection diodes (shown in the figure). The faster the transmission speed, the lower the center voltage of the signal transmission. For example, the center voltage of the TX / RX signals in USB4 is only 1V. Therefore, electrostatic surges can easily damage the corresponding high-speed ports of the chip. Simultaneously, the faster the signal transmission speed, the greater the impact of bypass phenomena, Integrated Multic Reflection (IMR), Integrated Return Loss (IRL), and parasitic capacitances and inductances on the signal transmission speed. Therefore, many devices often do not add ESD protection to ensure signal transmission speed. The principle of ESD protection is that once the ESD surge voltage exceeds a certain range, the TVS diode conducts, conducting the surge charge to ground, eliminating the risk of damage to the high-speed ports of the corresponding devices, and further preventing damage to the transmission equipment caused by ESD.

[0052] Furthermore, in this embodiment, as Figure 5 and Figure 6As shown: The female connector metal shielding shell 12 is configured as a flat, round shape with open ends, and is fitted onto the outside of the circuit board inner support 13 and the female connector integrated circuit board 11. A Type-C standard insertion port 123 is formed on the second end face 122 of the female connector metal shielding shell 12. A metal shielding overlap portion 1211 extends from the upper and lower surfaces of the first end face 121 of the female connector metal shielding shell 12. The metal shielding overlap portion 1211 overlaps with the Type-C male connector A, making the insertion between the Type-C male connector A and the Type-C female connector B in this embodiment more secure. When the Type-C male connector A is inserted into the Type-C female connector B, the Type-C male connector A is inserted into the first end face 121 of the Type-C female connector B in this embodiment. A portion of the Type-C male connector A is accommodated within the vertically extending metal shielding overlap portion 1211, and the insertion structure between the Type-C male connector A and the Type-C female connector B is locked by the outer shell 15.

[0053] The first end face 121 has a clearance notch 1212 on its left and right sides, and the clearance notch 1212 exposes the grounding point 113 of the female connector integrated circuit board 11 in this embodiment.

[0054] In this embodiment, the second end face 122 of the female metal shielding shell 12 has an outer edge 1221 of the metal shielding shell, and the metal shielding shell connecting protective sleeve 14 is sleeved on the female metal shielding shell 12 and abuts against the outer edge 1221 of the metal shielding shell. Several spring pieces 124 extend inward from the upper and lower end faces of the female metal shielding shell 12 near the insertion interface 123. When the external data cable is inserted, it is clamped by the upper and lower spring pieces 124 and is not easy to fall off. The inner surface of the upper and lower end faces is provided with multiple metal shielding shell abutment protrusions 125. When the female metal shielding shell 12 is sleeved on the outside of the circuit board inner support member 13 and the female integrated circuit board 11, the metal shielding shell abutment protrusions 125 abut against the limiting groove 131 on the circuit board inner support member 13 for limiting.

[0055] The female connector metal shield 12 and the circuit board inner support 13 abut against the limiting groove 131 of the circuit board inner support 13 through the metal shield abutment protrusion 125 of the metal shield 125, further limiting the female connector integrated circuit board 11 to form the insertion interface 123 of the TYPE-C female connector B; the first end face 121 of the female connector metal shield 12 abuts against the grounding point 113 of the female connector integrated circuit board 11, and the outer edge 1221 of the metal shield 122 of the second end face 122 abuts against the end of the circuit board 11, thus ensuring the grounding effect. The female connector metal shield 12 can also be connected to the grounding point 113 of the female connector integrated circuit board 11 by soldering; the first end face 121 of the female connector metal shield 12 overlaps with the metal shell of the Type-C male connector A through the metal shield overlap part 1211, and is reinforced by spot welding, encapsulating the core component of the Type-C female connector.

[0056] Furthermore, in this embodiment, a metal shielding shell connecting protective sleeve 14 is also included. The outer surface of the metal shielding shell connecting protective sleeve 14 has outwardly protruding vertical ribs 141 and inner ribs 142 that abut against the outer edge of the metal shielding shell 12. The metal shielding shell connecting protective sleeve 14 is sleeved with the metal shielding shell 12 of the core component that completes the anti-static Type-C female connector. The inner ribs 142 of the metal shielding shell connecting protective sleeve 14 abut against the outer edge 1221 of the metal shielding shell 12.

[0057] Furthermore, in this embodiment, the outer shell 15 is the metal shielding shell connecting protective sleeve 14 that has been fitted together. The core component of the anti-static Type-C female connector is integrally injection molded by a mold and fitted onto the protective sleeve 14. The outer shell 15 has multiple through holes 151 that match the vertical ribs 141. When the outer shell 15 is fitted onto the metal shielding shell connecting protective sleeve 14, the vertical ribs 141 extend out through the through holes 151.

[0058] like Figure 2-7As shown: The assembly process of the anti-static TYPE-C female connector of the present invention is as follows: the female connector integrated circuit board 11 and the circuit board inner support 13 are integrated components or two components combined and fixed in other forms; the female connector metal shielding shell 12 is sleeved on the outside of the female connector integrated circuit board 11 and the circuit board inner support 13, the metal shielding shell abutment protrusion 125 on the inner surface of the female connector metal shielding shell 12 abuts and limits the limiting groove 131 of the circuit board inner support 13, forming the Type-C female connector interface 123, the metal shielding overlap part 1211 overlaps with the metal shell of the Type-C male connector A, and is reinforced by spot welding, encapsulating the core component of the Type-C female connector B; then the metal shielding shell connecting protective sleeve 14 is sleeved on the female connector metal shielding shell 12, the metal shielding shell connecting protective sleeve 14 is outer sleeved, and the outer shell 15 is connected to the vertical rib 141 through the through hole 151.

[0059] The advantages of this invention are:

[0060] (1) In this invention, the female metal shield 12 is directly sleeved on the outside of the female integrated circuit board 11 and the support member 13 inside the circuit board to form a Type-C female connector interface 123. The gold fingers 111 of the female integrated circuit board 11 are directly used as the plug-in component of the standard Type-C female connector. Not only does it not require soldering, but it is a direct connection method, which minimizes the factors of impedance change and effectively avoids the generation of static electricity during repeated plugging and connection, thus protecting the connected equipment from the risk of static electricity damage.

[0061] (2) The present invention forms a Type-C female connector interface 123 by simply attaching the female connector metal shield shell 12 to the outside of the female connector integrated circuit board 11 and the circuit board inner support 13, and the metal shield shell connecting the protective sleeve 14 and the outer shell 15. The assembly process is simpler, which not only reduces the difficulty and cost of the production process, but also further reduces the performance risk caused by improper welding of electrical connection components.

[0062] In summary, the foregoing disclosure of this invention is intended to enable those skilled in the art to clearly understand the technical content of this invention and implement it accordingly, and is not intended to limit the scope of patent protection of this invention. In addition, this invention may naturally have other embodiments not listed. Without departing from the spirit and essence of this invention, those skilled in the art should be able to devise various corresponding changes and modifications based on this invention, but all such changes and modifications should fall within the scope of protection of the patent application filed for this invention.
