Description

USB electrical connector, detachable socket for easy maintenance

The present invention relates to a USB electrical connector, particularly a detachable socket that is easy to maintain.

According to the report, USB electrical connectors have been widely used in electronic devices as interfaces for power and signal transmission. However, with the increase in transmission volume and performance requirements, USB has introduced high-speed Type-C electrical connectors. Its appearance size is smaller than that of traditional USB interfaces, but it can support higher power charging and power supply capabilities. Therefore, it has become a mainstream connection interface, just like the new iPhone 15 has also switched to Type-C connectors. Users can connect peripheral devices with USB male plugs, such as headphones, mice, external hard drives, mobile power supplies, and even charging cables, to the sockets on electronic devices.

However, in the USB Type-C electrical connector, since the interface size of the female socket is smaller, and the connecting terminals of the male and female ends are connected to each other in a planar manner to form an electrical connection, its structural strength is weak and it is easy to be damaged by repeated plugging and unplugging operations.

Next, a known USB Type-C electrical connector socket 10A is shown in FIGS. 1A and 1B , and mainly comprises an insulating package body 12 in a metal shielding cover 11, and a front end surface of the insulating package body 12 extends outward in a horizontal direction to form a tongue 13, and a plurality of upper terminals 131 and a plurality of lower terminals (not shown) are arranged in the insulating package body 12 and its tongue 13, and one end of each upper terminal 131 and each lower terminal is partially exposed on the upper and lower surfaces of the tongue 13, respectively, for electrical contact. Furthermore, the electrical connector socket 10A has a positioning foot 14 on both sides thereof, which is opposite to the insertion hole 21 on the circuit board 20 to be connected, and the insulating package body 12 has arranged conductive terminals 15a at the rear end thereof, which is opposite to the electrical connection hole 22a of the circuit board 20. Accordingly, as shown in FIG. 1B , the electrical connector female socket 10A can be fixed on the circuit board 20 by plugging.

Another known USB Type-C electrical connector socket 10B is shown in Figures 2A and 2B. The difference between it and the above-mentioned electrical connector female socket 10A is that the rear end of the insulating package body 12 is provided with arranged conductive terminals 15b relative to the electrical connection metal surface 22b of the circuit board 20. Therefore, as shown in Figure 2B, the electrical connector female socket 10B can be fixed on the circuit board 20 by welding.

Next, FIG. 3 shows a known USB Type-C electrical connector socket 10C, which has a transmission cable 16 (which can be a single-row cable or a double-row cable) fixedly connected to its body, and then the tail end 161 of the transmission cable 16 is connected to the motherboard inside the electronic device.

However, according to the specifications set by the USB Type-C electrical connector, the electrical connector must have a plug-in and pull-out tolerance of more than 10,000 times, and must also pass the 4-axis test. However, the interface size of the USB Type-C electrical connector is only 8.3×2.5 mm, and its tongue 13 is only 0.7 mm, but it is the most concentrated point of 4-axis force, so it is easy to cause the tongue 13 to be damaged after frequent plugging and unplugging, thereby affecting normal operation. In addition, as the number of plug-in and unplugging times of the electrical connector increases, the tongue 13 of the electrical connector socket is easily displaced by force, and the displacement of the tongue 13 may cause damage to the structure or function of 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 treatment method is to disassemble the motherboard of the electronic device for inspection or replacement. Not only is the process cumbersome, but the maintenance cost is also high. Moreover, in most cases, the motherboard is not damaged at all, but only the electrical connector socket is damaged. However, because the electrical connector socket has been plugged or welded on the motherboard (circuit board) when it leaves the factory, even the undamaged motherboard needs to be replaced, resulting in a huge waste.

In addition, since the traditional electrical connector socket is already plugged or soldered on the motherboard (circuit board) when it leaves the factory, another disadvantage is that the general electrical connector socket is installed at the center line position of the electronic device. For example, in the case of a laptop, it is installed at the center line (C) of the body 50 as shown in Figure 7. In this way, for models of different thicknesses or specifications, the motherboard electrical connector socket that can match its center line (C) must be manufactured according to demand, so it must be very accurate, otherwise the electrical connector socket will often not be on the center line (C) of the body 50 after the motherboard is installed, causing great trouble.

Therefore, how to develop an electrical connector that can improve the problems encountered by the above-mentioned prior art is the problem that this invention aims to solve.

The main purpose of the present invention is to provide a detachable socket for easy maintenance of the USB electrical connector, which has the function of improving the convenience of maintenance.

The present invention can also be implemented or applied through other different specific embodiments. The details in this manual can also be modified and changed based on different viewpoints and applications without deviating from the spirit of the present invention.

First, please refer to FIG. 4A to FIG. 5B. The present invention is a separable socket for easy maintenance of a USB electrical connector. The first feasible embodiment includes: a separable unit 30, including a first insulating package body 31, the front end of the first insulating package body 31 is provided with a tongue 36, the outer periphery of the tongue 36 is covered by a metal shell to form a plug interface 35, and the metal shell is provided with a shielding cover 34; however, it is found that the prior art (Prior Art) of the USB electrical connector is not the patent subject of the present invention, and it is not necessary to elaborate.

The main feature of the present invention is that the rear end of the first insulating package body 31 forms a vertical surface, and a protruding plate 32 is formed by extending outward in a horizontal direction from the vertical surface. The upper and lower surfaces of the protruding plate 32 are provided with a plurality of arranged conductive gold fingers (Connecting Finger) 321, and the vertical surface is provided with a first bonding portion 33 on both sides of the protruding plate 32.

A fixing unit 40 is directly fixed on a circuit board 20 or a transmission cable 70, and includes a second insulating package body 41. The front end surface of the second insulating package body 41 is opposite to the conductive gold finger 321 of the protruding plate 32, and is provided with a plurality of conductive terminals 42 arranged in a row. The front end surface of the second insulating package body 41 is on both sides of the conductive terminal 42, opposite to the first The position of the coupling portion 33 is provided with a second coupling portion 43 that can guide and fit with it, so that the detachable unit 30 and the fixed unit 40 fit with each other to form a USB electrical connector socket 50, and when the detachable unit 30 fails or is damaged, it can be independently pulled out from the circuit board 20 or the transmission cable 44 without disassembling or replacing the circuit board 20 or the transmission cable 44. In this embodiment, the USB electrical connector socket 50 can be a Type-C electrical connector specification, but is not limited thereto.

As shown in FIG. 4A to FIG. 5B, in the first feasible embodiment of the present invention, the first coupling portion 33 may be in the form of a coupling hole 33a, and the second coupling portion 43 may be in the form of a coupling protrusion 43a that can be embedded in the coupling hole 33a, so that the two can fit tightly with each other.

Please continue to refer to FIG. 6A , which shows the second feasible embodiment of the present invention. The same structure as the first embodiment is indicated by the same figure number, and the difference is that the first coupling part 33 can be a coupling protrusion 33b, and the second coupling part 43 is a coupling hole 43b for the coupling protrusion 33b to be inserted, and the two can fit tightly with each other.

The coupling hole 33a or 43b disclosed in the first and second embodiments above is a circular hole, but is not limited thereto. That is, as shown in FIG6B , the third feasible embodiment of the present invention discloses that the coupling hole 33 can be a rectangular hole 33c or other geometric holes in addition to the aforementioned circular hole; and the coupling protrusion 33b can be set as a rectangular protrusion 43c or a corresponding geometric protrusion.

Please refer to Figures 7A to 8B, which show the USB electrical connector socket 50 of the present invention used in an electronic device 60. The electronic device 60 may be a notebook computer, but is not limited thereto. The conductive terminal 42 of the fixing unit 40 of the USB electrical connector socket 50 extends backward from the rear end of the second insulating package body 41 to form a plurality of conductive pins 421 that can be plugged or welded to the circuit board (motherboard) 20.

In this embodiment, the fixed unit 40 of the USB electrical connector socket 50 is fixedly connected to the transmission cable 70 to form a transmission device 70A having the fixed unit 40, but the detachable unit 30 is not fixed to the transmission cable 70, and the detachable unit 30 and the fixed unit 40 can only be tightly fitted with each other to form the USB electrical connector socket 50. In other words, the detachable unit 30 is an independent unit that is detachable and can be separated and replaced from the transmission device 70A.

In the USB Type-C electrical connector, the female socket has a smaller interface size, and the male and female terminals inside the connector are electrically connected by planes that are connected to each other. Therefore, the structural strength is weak and it is easy to be damaged by repeated plugging and unplugging. In other words, the tongue of the traditional electrical connector socket is the most easily damaged part. If the tongue is damaged, the entire circuit board or transmission cable must be removed for repair or replacement. Not only is the process cumbersome, but the repair cost is also high. Sometimes even the motherboard that is not damaged needs to be replaced, which is a huge waste.

Therefore, the present invention uses the above-mentioned technical means to set the most easily damaged part of the USB electrical connector socket 50 into a detachable independent unit, so that maintenance is very convenient. It only needs to replace the detachable unit 30 without moving the motherboard at all. It is not only time-saving and convenient, but also avoids waste of resources, and has the effect of environmental protection and reducing maintenance costs.

In summary, the technical means disclosed in this invention do meet the patent requirements of "novelty", "progressiveness" and "availability for industrial use". We pray that the Bureau of Industry will grant patents to encourage inventions, without any sense of gratitude.

However, the above disclosed diagrams and descriptions are only the preferred embodiments of the present invention.
