Description

Technical Field

[0001] This utility model relates to the field of FPC adapter cable technology, specifically a waterproof charging FPC adapter cable for mobile communication. Background Technology

[0002] Mobile communications are a communication method that connects mobile users with fixed-point users or between mobile users. One or both parties in the communication are in motion. It includes land, sea, and air mobile communications. The frequency bands used cover low frequency, medium frequency, high frequency, very high frequency, and ultra-high frequency. A mobile communication system consists of mobile stations, base stations, and a mobile switching center. To communicate with a specific mobile station, the mobile switching center sends a call to the entire network through the base stations. Upon receiving the call, the called station sends an answer signal. After receiving the answer, the mobile switching center allocates a channel to the mobile station and transmits a signaling message through this channel to make it ring. Mobile communication is a modern technology for wireless communication, and it is one of the important achievements of the development of electronic computers and the mobile Internet. After the development of first, second, third, and fourth generation technologies, mobile communication technology has now entered the fifth generation era (5G mobile communication technology). This is one of the major technologies that are changing the world. Modern mobile communication technology can be mainly divided into several frequency bands: low frequency, medium frequency, high frequency, very high frequency, and ultra-high frequency. Within these frequency bands, technicians can use mobile station technology, base station technology, and mobile switching technology to connect terminal devices within the mobile communication network to meet people's mobile communication needs. From analog mobile communication systems, digital cellular communication systems, and mobile multimedia communication systems to the current high-speed mobile communication systems, the speed of mobile communication technology has continuously improved, latency and bit error rates have decreased, and the stability and reliability of the technology have continuously improved, providing people with a variety of flexible communication methods for their production and daily life.

[0003] Flexible printed circuit boards (FPCs) are essential components in mobile communication devices. These cables adhere to industry-specific standards regarding wiring rules, wire sequence, wire color, and wire numbering. They are used for data transmission within moving parts and areas, such as data cables connecting the motherboard to the hard drive and optical drive in a computer, data cables connecting the motherboard to the display screen in a mobile phone, and data cables connecting devices. FPCs are small and lightweight, and were initially designed to replace bulky wire harnesses. In current cutting-edge electronic device assembly boards, FPCs are often the only solution to meet miniaturization and mobility requirements. FPCs (sometimes called flexible printed circuits) involve etching copper circuits or printing thick polymer film circuits onto a polymer substrate. For thin, lightweight, and complex devices, design solutions range from single-sided conductive lines to complex multi-layer three-dimensional assemblies. The overall weight and volume of FPCs are reduced by 70% compared to traditional round wire harnesses. FPCs can also increase their strength by using reinforcing materials or backing plates to achieve additional mechanical stability.

[0004] Ribbon cables can be moved, bent, and twisted without damaging the conductors, and can conform to various shapes and special package sizes. Their only limitation is space constraints. Because they can withstand millions of dynamic bends, ribbon cables are well-suited for use in interconnect systems with continuous or periodic motion, becoming an integral part of the final product's functionality.

[0005] Ribbon cables possess excellent electrical, dielectric, and heat resistance properties. Good thermal performance facilitates component cooling; higher glass transition temperatures or melting points allow components to operate well at higher temperatures, resulting in higher assembly reliability and quality. Ribbon cables reduce the hardware required for internal connections, such as solder joints, relays, baseboard circuitry, and cables commonly used in traditional electronic packaging, enabling them to provide higher assembly reliability and quality. Traditional internal connections, composed of complex multiple systems, are prone to high component misalignment rates during assembly. Ribbon cables have low stiffness and small size; the smaller size of the ribbon cable board components also reduces the amount of material used. With the advent of quality engineering, a very thin flexible system is designed to be assembled in only one way, eliminating many human errors typically associated with independent wiring projects. While the adapter cable has good external waterproofing, the lack of shielding at the connection point after the waterproof charging FPC adapter cable for mobile communications is connected to communication equipment makes it susceptible to short circuits if water is splashed onto the connection. Utility Model Content

[0006] The purpose of this utility model is to provide a waterproof charging FPC adapter cable for mobile communication, which solves the problem that when the waterproof charging FPC adapter cable for mobile communication is connected to the communication equipment, the connection part is not equipped with a shielding structure, which makes it easy to cause short circuits if water is splashed on the connection point.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a waterproof charging FPC adapter cable for mobile communication, comprising an outer casing of a mobile communication device, an interface mounting hole on the left side of the outer casing communicating with the right side, a device interface being snapped into the interior of the interface mounting hole, an assembly plate being fixedly connected to the top of the device interface, the assembly plate being fixedly installed to the outer casing of the mobile communication device by bolts, a cable plug being inserted into the right side of the device interface, a cable body being connected to the right side of the cable plug, a rectangular frame being slidably connected to the surface of the cable body, a protective cover being fixedly connected to the outer surface of the rectangular frame, a rubber sealing structure being fixedly connected to the left side of the protective cover, a contact groove being provided on the right side of the outer casing of the mobile communication device, and the surface of the rubber sealing structure engaging with the interior of the contact groove.

[0009] Furthermore, the rubber sealing structure is rectangular in shape, which is adapted to the left side frame of the protective cover.

[0010] Furthermore, an inclined support plate is fixedly connected to the right side of the outer casing of the mobile communication device, and an absorbent sponge is adhered to the upper surface of the inclined support plate.

[0011] Furthermore, a reinforcing groove is provided on the right side of the ribbon cable plug, and a pin is engaged inside the reinforcing groove.

[0012] Furthermore, the right end of the pin is fixedly connected to the left side of the rectangular frame. After the ribbon cable plug is inserted into the device interface, the rectangular frame is pulled to the left on the surface of the ribbon cable body. The assembly plate moves the protective cover to cover the connection between the ribbon cable plug and the device interface. At the same time, the rubber sealing structure will also be inserted into the inside of the contact groove to increase the sealing performance. The pin will follow the movement of the rectangular frame and be inserted into the inside of the reinforcing groove to increase the firmness of the protective cover. When a small amount of water is splashed, the water-absorbing sponge can absorb the water to prevent water from entering the connection between the ribbon cable plug and the device interface.

[0013] Furthermore, the protective cover is made of insulating material.

[0014] This utility model provides a waterproof charging FPC adapter cable for mobile communication. It has the following advantages:

[0015] This waterproof charging FPC adapter cable for mobile communication uses a combination of a protective cover, contact groove, rubber sealing structure, pin, reinforcing groove, and rectangular frame to shield the connection point of the adapter cable, preventing water from affecting its normal operation. At the same time, the water-absorbing sponge and the inclined support plate can further protect it. Small amounts of water can be directly absorbed. This solves the problem that when the waterproof charging FPC adapter cable for mobile communication is connected to the communication equipment, the connection point does not have a shielding structure, which makes it easy for water to cause short circuits when it is splashed at the connection point.

[0024] like Figure 1-3 As shown, this utility model embodiment provides a waterproof charging FPC adapter cable for mobile communication, including an outer shell 1 of a mobile communication device. The outer shell 1 of the mobile communication device has an interface mounting hole 2 on the left side that communicates with the right side. A device interface 3 is snapped into the inside of the interface mounting hole 2. An assembly plate 5 is fixedly connected to the top of the device interface 3. The assembly plate 5 is fixedly installed to the outer shell 1 of the mobile communication device by bolts 4.

[0025] In the first embodiment of this utility model, a ribbon cable plug 6 is inserted into the right side of the device interface 3, and a ribbon cable body 7 is connected to the right side of the ribbon cable plug 6. An inclined support plate 10 is fixedly connected to the right side of the outer shell 1 of the mobile communication device.

The pin 13 will follow the movement of the rectangular frame 15 and be inserted into the inside of the reinforcing groove 14 to increase the firmness of the protective cover 8. When a small amount of water is splashed, the water-absorbing sponge 9 can absorb the water to prevent water from entering the connection between the ribbon cable plug 6 and the device interface 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
