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] However, according to the specifications of USB Type-C electrical connectors, the connector must withstand more than 10,000 mating cycles and pass a 4-axis test. However, the interface size of the USB Type-C connector is 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. Furthermore, with the increase in the number of mating and unmating cycles, the tongue 13 of the connector socket is prone to displacement due to stress, which may lead to structural or functional damage to the connector. Since the connector socket is usually directly built into the motherboard of the electronic device, when the structure or function of the 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 been plugged in or soldered onto the motherboard at the factory, even the undamaged motherboard needs to be replaced, resulting in a huge waste. Utility Model Content

[0008] The purpose of this invention is to solve the problem of the difficulty in inspecting whether the electrical connector sockets on electronic devices are damaged, and to make it convenient to inspect whether the electrical connector sockets on electronic devices are damaged.

[0009] Another objective of this invention is to enable the replacement of only the damaged electrical connector socket.

[0010] To achieve the above objectives, the specific technical solution of this utility model is as follows: It includes: A positioning base has a base plate, a vertical plate, a top plate, and a pair of side plates. The vertical plate is formed at one end of the base plate, and the top plate and the opposite side plates are formed on the vertical plate and located above the base plate. A groove is formed between the bottom edge of the opposite side plates and the top edge of the base plate. The positioning base is mounted on the motherboard of an electronic device using the groove, with the vertical plate positioned precisely at the end edge of the motherboard. The vertical plate has a guide opening, and the top plate has a snap-fit ​​groove. A replaceable socket has a metal housing, an insulating bracket, and a number of pin terminals. The insulating bracket is disposed inside the metal housing, and each of the pin terminals is isolated and fixed to the insulating bracket. A tongue is formed at the front end of the insulating bracket, and a plug interface is formed between the tongue and the metal housing. Each of the pin terminals has a tongue exposed portion at its front end, and a spring contact pin is connected to the rear end of each of the pin terminals. A snap-fit ​​protrusion is formed on the top edge of the metal housing, and the snap-fit ​​protrusion snaps into the snap-fit ​​groove. The replaceable socket is placed on the positioning seat, and the plug interface is aligned with the guide port, and each spring contact pin abuts against the electrical connection pad of the motherboard.

[0011] Furthermore, each of the terminals has a pin exposed portion at its rear end, and each spring pin is connected to the pin exposed portion. Attached Figure Description

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0015] The following is a reference to the appendix. Figure 4 To be continued Figure 9 The present invention comprises: a positioning base 30 and... A replaceable socket 40; the positioning base 30 has a base plate 31, a vertical plate 32, a top plate 33 and a pair of side plates 34. The vertical plate 32 is formed at one end of the base plate 31. The top plate 33 and the pair of side plates 34 are formed on the vertical plate 32 and located above the base plate 31. The bottom edge of the pair of side plates 34 and the top edge of the base plate 31 are formed into a groove 35. The positioning base 30 is set on the motherboard 20 of the electronic device using the groove 35, and the vertical plate 32 is located at the end edge of the motherboard 20. The vertical plate 32 has a guide opening 321 and the top plate 33 has a snap-fit ​​groove 331.

[0016] The replaceable socket 40 has a metal housing 41, an insulating bracket 42, and a number of pin terminals (not shown). The insulating bracket 42 is disposed inside the metal housing 41, and each pin terminal is isolated and fixed to the insulating bracket 42. A tongue 421 is formed at the front end of the insulating bracket 42, and the distance between the tongue 421 and the metal housing 41 is formed into a plug interface 422. Each pin terminal has a tongue exposed portion (not shown, commonly known as a gold finger) at its front end, and each pin terminal is connected to a connector at its rear end. A spring contact pin 43 is connected to each of the terminals. Each of the terminals has a pin exposed portion (not shown in the figure) at its rear end. Each spring contact pin 43 is connected to the pin exposed portion. A pair of snap-fit ​​protrusions 411 are formed on the top edge of the metal housing 41. The pair of snap-fit ​​protrusions 411 are snapped into the pair of snap-fit ​​grooves 331. The replaceable socket 40 is placed on the positioning seat 30, and the plug interface 422 is aligned with the guide port 321. Each spring contact pin 43 is in contact with the electrical connection pad 22b of the motherboard 20.

The positioning base 30 is positioned on the motherboard 20 of the electronic device using the recess 35, and the replaceable socket 40 is positioned on the positioning base 30 using the snap-fit ​​relationship between the snap-fit ​​protrusion 411 and the snap-fit ​​groove 331. When the electrical connector socket on the electronic device malfunctions, the snap-fit ​​relationship between the snap-fit ​​protrusion 411 and the snap-fit ​​groove 331 is released, and the replaceable socket 40 can be easily and quickly disassembled for testing. This allows for a quick determination of whether the malfunction is in the replaceable socket 40 or the motherboard 20, thus facilitating the inspection and repair of whether the electrical connector socket on the electronic device is damaged. If the replaceable socket 40 malfunctions, simply snapping a new replaceable socket 40 onto the positioning base 30 will restore the electrical connector socket on the electronic device to normal function, without having to replace the entire motherboard 20. This allows for the replacement of only the damaged electrical connector socket.
