Description

Technical Field

[0001] This utility model relates to a USB socket module that is easy to maintain, and more particularly to a design that modularizes the USB socket into a positioning base and a replaceable socket for easy maintenance. Background Technology

[0002] USB connectors are widely used in electronic devices as interfaces for power and signal transmission. However, with the increasing demands for transmission volume and performance, USB has introduced high-speed Type-C connectors. These connectors are smaller than traditional USB interfaces but support higher power charging and supply capabilities. Therefore, they have become the mainstream connection interface. For example, the new iPhone 15 uses Type-C connectors across the board. Users can connect peripherals with USB plugs, such as headphones, mice, external hard drives, power banks, and even charging cables, to the sockets on electronic devices.

[0003] In USB Type-C electrical connectors, the socket has a relatively small interface size, and the internal male and female terminals are connected by planar contact to form an electrical connection. Therefore, its structural strength is relatively weak and it is easily damaged by repeated plugging and unplugging.

[0004] A known USB Type-C electrical connector socket 10A is as follows: Figure 1A , 1B As shown, an insulating support 12 is mainly provided inside a metal housing 11. One front end of the insulating support 12 extends horizontally outward to form a tongue 13. A plurality of terminals (not shown) are provided within the insulating support 12 and the tongue 13, with each terminal partially exposed on the upper and lower surfaces of the tongue 13 for electrical contact. Furthermore, the electrical connector socket 10A has a positioning pin 14 on both sides corresponding to the insertion hole 21 on a motherboard 20 to be connected, and the rear end of the insulating support 12 has an arranged conductive terminal 15a corresponding to the electrical connection hole 22a of the motherboard 20. Accordingly, as... Figure 1B As shown, the electrical connector socket 10A can be fixed to the motherboard 20 by plugging in.

[0005] Another known USB Type-C electrical connector socket 10B is as follows: Figure 2A , 2B As shown, its difference from the aforementioned electrical connector socket 10A is that the rear end of the insulating bracket 12, relative to the electrical connection pad 22b of the main board 20, has arranged conductive terminals 15b, thereby enabling... Figure 2B As shown, the electrical connector socket 10B can be fixed to the motherboard 20 by soldering.

[0006] Figure 3 The diagram shows a known USB Type-C electrical connector socket 10C, on which a transmission cable 16 (which can be a single or double cable) is pre-connected, and the tail end 161 of the transmission cable 16 is connected to the motherboard inside the electronic device.

[0007] According to the specifications for USB Type-C electrical connectors, these connectors must withstand more than 10,000 mating cycles and pass a 4-axis test. However, the interface dimensions of a USB Type-C electrical connector are only 8.3 × 2.5 mm, and its tongue 13 is only 0.7 mm, yet it is the point where the 4-axis stress is most concentrated. Therefore, the tongue 13 is easily damaged after frequent mating and unmating, thus affecting normal operation. In addition, with the increase in the number of mating and unmating cycles, the tongue 13 of the electrical connector socket is prone to displacement due to stress, which may lead to structural or functional damage to the electrical connector. Since the electrical connector socket is usually directly built into the motherboard of the electronic device, when the structure or function of the electrical connector socket is damaged, the current approach is to disassemble the motherboard of the electronic device for inspection or replacement, which is not only cumbersome but also expensive. Moreover, in most cases, the motherboard is not damaged at all; only the electrical connector socket is broken. However, since the electrical connector socket has already been plugged into or soldered onto the motherboard at the factory, even the undamaged motherboard needs to be replaced, resulting in a huge waste.
