Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, specifically relating to a Type-C connector with a flexible flat cable socket. Background Technology

[0002] In walkie-talkie devices, the interface typically serves multiple functions, including charging, data transmission, and functional expansion. As users' demands for fast charging, high-speed data interaction, and miniaturized design continue to increase, the USB Type-C interface, due to its advantages such as high integration, fast transmission speed, and reversible pluggability, has gradually been introduced into walkie-talkie products.

[0003] However, the Type-C interface typically employs a high-density 24-pin pin layout, placing extremely high demands on the manufacturing process. Current technologies mostly utilize surface mount technology to directly solder the Type-C female connector to the walkie-talkie motherboard. However, this method has the following drawbacks: First, walkie-talkies are compact with limited internal space, resulting in extremely small pin spacing, making them prone to bridging and cold solder joints during soldering, thus affecting production yield. Second, walkie-talkies are mostly used in outdoor environments, with high interface usage frequency. If the interface is damaged or the solder joint fails, it often requires disassembling and repairing the entire motherboard, which is risky, costly, and may even lead to the motherboard being scrapped. Therefore, improving the existing Type-C interface manufacturing process to address these issues has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a Type-C connector with a flexible flat cable socket to solve the technical problems of high soldering difficulty, high maintenance cost and poor connection reliability of the existing Type-C interface of walkie-talkies.

[0005] To achieve the above objectives, the technical solution provided by this utility model for a Type-C connector with a flexible flat cable socket is as follows: A Type-C connector with a flexible flat cable connector, characterized in that it comprises: Type-C female connector, the Type-C female connector being used to mate with an external male connector; The PCB board is physically connected to the Type-C female connector and electrically connected to the Type-C female connector. A flexible flat cable connector is provided on the PCB board and electrically connected to the PCB board, and is used to insert an external FPC flexible flat cable and electrically connect to the external FPC flexible flat cable.

[0006] Furthermore, one end of the Type-C female connector is a socket adapted to an external male connector, and the other end has multiple pins, which are soldered to the PCB board using a surface mount process; and the multiple pins are electrically connected to the PCB board.

[0007] Furthermore, the Type-C female connector has a pin end and a clamping member. The clamping member is integrally formed with the Type-C female connector and is distributed around the pins of the Type-C female connector. When multiple pins of the Type-C female connector are connected to the PCB board, the clamping member is used to fit and clamp the PCB board.

[0008] Furthermore, it also includes a housing that covers the outer periphery of the Type-C female connector, and the port of the Type-C female connector extends out of the housing; the housing is used for physical connection with external devices.

[0009] Furthermore, the pin-equipped end of the Type-C female connector is located within the accommodating cavity formed by the housing. After the clamping component is fitted and clamped to the PCB board, the accommodating cavity of the housing is filled by the plastic material component, and the pins of both the PCB board and the Type-C female connector are wrapped by the plastic material component.

[0010] Furthermore, the portion of the Type-C female connector that extends out of the outer shell is fitted with a silicone sealing ring, and the silicone sealing ring is in contact with the outer shell.

[0011] Furthermore, the outer casing is provided with threaded holes, which are used to physically connect the outer casing after being fitted with bolts.

[0012] Furthermore, the Type-C female connector is a 24-pin female connector.

[0013] Furthermore, the PCB board is provided with 16 pads for connecting the flexible flat cable connector. The pins of the 16 pads are defined as follows: C1, GND, USB DOWN, ENN, VBUSS, CC1, SBU2, SPK+, SPK-, SBU1, CC2, VUBS, TXD, RXD, GND, C16.

[0014] To achieve the above objectives, this utility model also provides a walkie-talkie including a Type-C connector with a flexible flat cable socket as described in any one of the above claims.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention solders a Type-C female connector onto a small PCB board, which has a flexible flat cable connector. The connector then connects to the walkie-talkie's mainboard via a flexible flat cable. Compared to existing technologies that solder the PCB board and mainboard, this solution significantly improves production yield and avoids issues like cold solder joints and bridging caused by directly soldering high-density pins. Furthermore, when the interface is damaged, repairs can be completed by replacing only the small PCB module, eliminating the need to disassemble the entire mainboard. This reduces repair difficulty and cost, prevents mainboard failure, and improves the walkie-talkie's reliability and ease of maintenance.

[0016] Based on further optimized shell and circuit design, this utility model enhances the mechanical strength and protection performance of the interface under high-frequency plugging and unplugging and harsh environments by setting a protective shell, silicone sealing ring, fixed wing plate and positioning post; at the same time, the reasonable PCB pad allocation and flexible flat cable connection design realize the composite transmission of charging, data transmission, audio signal and control signal, making the interface function comprehensive and expandable, effectively solving the problem of single function and poor expandability of existing walkie-talkie interfaces.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] The present invention will be further described in detail below with reference to the embodiments.

[0020] Specific embodiment 1 of the Type-C connector with flexible flat cable socket provided by this utility model: like Figure 1-3 As shown, a Type-C connector with a flexible flat cable connector includes a Type-C female socket 1, a PCB board 2, and a flexible flat cable connector 3.

[0021] The Type-C female connector 1 has a socket 4 at one end for mate with an external Type-C male connector, and multiple pins 11 at the other end. The Type-C female connector 1 is a standard 24-pin female connector to ensure compatibility with high-speed data transmission and expansion functions. The multiple pins 11 are soldered to the PCB board 2 using a surface mount process and are electrically connected to the PCB board 2. The flexible flat cable connector 3 is located on the PCB board 2 and is electrically connected to the PCB board 2. The flexible flat cable connector 3 is a zero insertion and extraction force connector, which facilitates the insertion of external FPC flexible flat cables and their electrical connection to the PCB board 2.

[0022] Compared to existing technologies, the Type-C female connector 1 in this application is not directly soldered onto the mainboard of the walkie-talkie, but is first soldered onto a small-sized PCB board 2. The PCB board 2 has a flexible flat cable connector 3. After the flexible flat cable is inserted into the connector 3, the other end connects to the walkie-talkie mainboard. This method avoids problems such as cold solder joints and bridging caused by directly soldering the high-density pins on the walkie-talkie mainboard, thus improving production yield. At the same time, when the Type-C female connector 1 is damaged, only the small PCB board 2 needs to be replaced to complete the repair, without having to disassemble and solder the mainboard of the entire walkie-talkie, thereby reducing the difficulty and cost of repair and avoiding the scrapping of the mainboard.

[0023] This structure is particularly suitable for walkie-talkie scenarios such as outdoor duty, construction communication, and emergency rescue. It can maintain a stable electrical connection and a long service life even under environments with frequent plugging and unplugging, vibration, and high temperature and humidity.

[0024] In this embodiment, the PCB board 2 is physically connected to the Type-C female connector 1 and electrically connected to the Type-C female connector 1. In this embodiment, the multiple pins 11 of the Type-C female connector 1 are directly soldered to the PCB board 2 by reflow soldering to form a rigid electrical connection; or the pins 11 are soldered after passing through the through holes of the PCB board 2 to form a structure of mechanical locking and electrical connection.

[0025] For the preferred solution, please refer to [link / reference]. Figure 4 and Figure 5The Type-C female connector 1 has one end with pins 11 and at least two pairs of clamping members 12. The clamping members 12 are integrally formed with the Type-C female connector 1, are made of metal, and are longer than the pins 11 of the Type-C female connector 1. The clamping members 12 are distributed around the pins of the Type-C female connector. When multiple pins of the Type-C female connector 1 are connected to the PCB board 2, the clamping members 12 are used to adapt to the PCB board 2 and clamp the PCB board. This further increases the strength of the connection between the Type-C female connector 1 and the PCB board 2. This connection method has high mechanical strength and can withstand the application scenarios of frequent vibration and frequent plugging and unplugging of walkie-talkies, such as vehicle-mounted or field-operated walkie-talkies.

[0026] In a preferred embodiment, the housing 8 is further included. The housing 8 covers the outer periphery of the Type-C female connector 1, with the Type-C female connector's socket extending out of the housing. The housing 8 is used for physical connection with external devices. When the housing 8 covers the Type-C female connector 1, the end of the Type-C female connector 1 with pins is also located within the accommodating cavity formed by the housing. After the clamping component is used to fit and clamp the PCB board 2, the space in the housing accommodating the end of the Type-C female connector 1 with pins 11 is filled with plastic material. At this time, the pins of both the PCB board 2 and the Type-C female connector 17 are wrapped by the filled plastic material 7, and the plastic material 7 is in contact with the housing 8, further reinforcing the connection between the Type-C female connector 1 and the PCB board 2, and also serving as a dustproof measure after filling. In this embodiment, the housing 8 is filled by injection molding, and the plastic material 7 is obtained after injection molding.

[0027] In this embodiment, the outer shell 8 protects the female connector 1 from direct external forces, and the outer shell 8 is used for physical connection with the walkie-talkie housing 9. This improves the reliability and environmental adaptability of the Type-C interface.

[0028] Preferably, the portion of the Type-C female connector 1 with its port 4 extending out of the outer casing 8 is fitted with a silicone sealing ring 10. The silicone sealing ring 10 is tightly fitted to the outer casing 8, thereby forming a seal when the interface is connected to the walkie-talkie casing, preventing dust or rainwater from seeping in and improving the walkie-talkie's waterproof and dustproof rating.

[0029] In addition, wing plates 81 are provided on both sides of the outer casing 8, and threaded holes 82 are provided on the wing plates 81. They can be fixedly connected to the walkie-talkie housing 9 by bolts, thereby ensuring that the interface remains stable under frequent plugging and unplugging or vibration environments. The top of the outer casing 8 is also provided with a positioning post 15, which is adapted to the corresponding hole in the walkie-talkie housing 9, which can further ensure assembly accuracy and stability.

[0030] The specific solution involves only opening holes on the wing plate 81, into which a metal part with internal threads is inserted to form a threaded hole.

[0031] Preferably, the outer shell 8 is made of metal or high-strength engineering plastic and is in the shape of a cuboid frame. Its outer surface can be provided with a reinforcing rib structure to improve impact resistance. The silicone sealing ring 10 adopts an annular protrusion design, which can form a reliable radial compression seal when docking.

[0032] Through the above structure, this embodiment not only ensures the mechanical strength of the Type-C connector, but also significantly enhances the reliability of the interface in harsh outdoor environments, effectively overcoming the problems of existing walkie-talkie interfaces being easily damaged and lacking sufficient protection in high-frequency plugging and unplugging and harsh environments. Especially in harsh environments such as field patrols, mine operations, and forest fire prevention communications, the combination of the outer shell 8 and the silicone sealing ring 10 can effectively prevent mud, sand, and rainwater from entering the interface, ensuring the continuous and stable operation of the walkie-talkie.

[0033] Example 2: In this embodiment, the flexible flat cable connector 3 is a zero insertion and extraction force connector, which facilitates the insertion of external FPC flexible flat cables and their electrical connection with the PCB board 2. When the PCB board 2 at the Type-C female connector 1 end is connected to the main board of the walkie-talkie via the FPC cable, the FPC can be bent to adapt to the complex internal structure of the walkie-talkie, while reducing the impact of vibration on the connection.

[0034] Preferably, the thickness of the PCB board 2 is about 0.6mm-1.0mm to fit the compact installation space inside the walkie-talkie; positioning holes can also be provided at both ends of the PCB board 2 to facilitate precise fixation on the walkie-talkie motherboard 7.

[0035] Example 3: This embodiment further optimizes the electrical connection design between the PCB board 2 and the flexible flat cable connector 3, based on embodiment two. For example... Figure 3 As shown, PCB board 2 has 16 pads 16 for electrical connection with the flexible flat cable connector 3. The pins of the 16 pads 16 are arranged sequentially and defined as follows: C1, GND, USB DOWN, ENN, BVBUSS, CC1, SBU2, SPK+, SPK-, SBU1, CC2, VUBS, TXD, RXD, GND, C16. This pin assignment not only meets the requirements of high-speed USB data transmission, but also supports audio signal transmission (SPK+ / SPK-), charging and power supply (VBUSS, VUBS), control signal interaction (CC1, CC2, ENN), and serial communication (TXD, RXD), realizing multi-functional expansion with one port; allowing this connection port of the walkie-talkie to simultaneously perform the functions of charging, audio transmission, and signal control.

[0036] Preferably, the contacts of the flexible flat cable connector 3 are gold-plated to improve contact reliability and oxidation resistance; the flexible flat cable 6 is arranged in parallel at equal intervals with a thickness of less than 0.3mm, which can be bent and installed in a limited space to adapt to the narrow internal structure of the walkie-talkie housing 9.

[0037] Therefore, this embodiment achieves composite transmission of charging, data, audio, and control signals through circuit optimization, providing comprehensive and expandable functionality and solving the problems of limited functionality and poor expandability of existing walkie-talkie interfaces.

[0038] In applications, users can achieve functions such as charging, data synchronization, connecting external voice devices, and remote control of the walkie-talkie through a single interface, which greatly improves the efficiency of interface usage and the product's scalability.

[0039] Example 4: In this embodiment, the arrangement of the flexible flat cable connector 3 is optimized. The direction of the connector 3 is set perpendicular to the direction of the connector 4 of the Type-C female connector 1, instead of the traditional parallel arrangement. The vertical design allows the flexible flat cable connector 3 and the Type-C female connector 1 to form an orthogonal layout on the PCB board 2. The Type-C female connector 1 is installed horizontally along the short side of the PCB board, while the flexible flat cable connector 3 is arranged vertically along the long side. This design can compress the two interfaces that originally needed to be arranged in parallel to the vertical direction, saving about 10-20% of the horizontal space, freeing up space for the battery compartment or antenna module inside the walkie-talkie. At the same time, the signal transmission directions of the flexible flat cable connector 3 and the Type-C female connector 1 are perpendicular to each other, which can reduce the electromagnetic coupling between the two. The mutual inductance coupling coefficient of the perpendicularly crossed signal lines is significantly reduced compared to parallel wiring.

[0040] Example 5: Example 5 illustrates the manufacturing process of a Type-C connector with a flexible flat cable connector according to this application: Step 1: The "Type-C female connector + PCB" is designed as an independent module. Step 2: Injection molding to encase the Type-C female connector. Step 3: Solder the flexible flat cable connector 3 onto PCB board 2.

[0041] The core of the above process is "processing components first, then injection molding for protection". Steps 1 and 3 are based on the control parameters of the walkie-talkie's requirements for "miniaturization, anti-interference, and environmental resistance". The connection reliability between the Type-C female connector and the PCB is improved through structural design, and the vibration resistance of the shell 8 is enhanced with PC / ABS alloy. Finally, the entire process is tested to ensure that the terminals can still work stably under predetermined number of insertions and removals, high and low temperature / vibration environments, and meet the long-term use requirements of the walkie-talkie.
