Description

Technical Field

[0001] The present invention relates to a USB electrical connector, in particular to a detachable socket which is easy to maintain. Background Art

[0002] USB connectors are widely used in electronic devices as interfaces for power and signal transmission. However, with increasing demands for data transfer and performance, USB has introduced the high-speed Type-C connector. While smaller than traditional USB ports, it supports higher charging and power delivery capabilities. As a result, it has become a mainstream connection interface, with the iPhone 15 adopting the Type-C connector across all models. Users can connect peripheral devices with a male USB plug, such as headphones, mice, external hard drives, power banks, and even charging cables, to the socket on electronic devices.

[0003] However, investigations have shown that the USB Type-C electrical connector has a relatively small female socket interface and that the male and female terminals inside the connector are electrically connected by flat surfaces that mate with each other. This results in a relatively weak structural strength and makes it susceptible to damage from repeated plugging and unplugging.

[0004] Secondly, a known USB Type-C electrical connector socket 10A, such as Figure 1A 、 1B As shown, an insulating package body 12 is provided in a metal shielding cover 11. The front end of the insulating package body 12 extends outward in a horizontal direction to form a tongue 13. Several upper terminals 131 and several lower terminals (not shown) are provided in the insulating package body 12 and its tongue 13. 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, positioning pins 14 are provided on both sides of the electrical connector socket 10A relative to the insertion holes 21 on the circuit board 20 to be connected, and the rear end of the insulating package body 12 is provided with arranged conductive terminals 15a relative to the electrical connection holes 22a of the circuit board 20. Accordingly, as shown in FIG. Figure 1B As shown, the electrical connector female socket 10A can be fixed on the circuit board 20 in a plug-in manner.

[0005] Another known USB Type-C electrical connector socket 10B, such as Figure 2A 、 2B As shown, the difference between it and the above-mentioned female electrical connector 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. Figure 2B As shown, the electrical connector female socket 10B can be fixed on the circuit board 20 by welding.

[0006] Furthermore, Figure 3 The figure shows a conventional USB Type-C electrical connector socket 10C, the body of which is first fixedly connected with a transmission cable 16 (which can be a single-row cable or a double-row cable), and then the tail end 161 of the transmission cable 16 is connected to the motherboard inside the electronic device.

[0007] However, according to the specifications set by the USB Type-C electrical connector, the electrical connector must have a plug-in and pull-out endurance of more than 10,000 times and must also pass a four-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. However, this is where the force in the four axes is most concentrated. Therefore, the tongue 13 is easily 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 the force. The displacement of the tongue 13 may cause damage to the structure or function of the electrical connector. Because the electrical connector socket is usually built directly into the motherboard of the electronic device, when the structure or function of the electrical connector socket is damaged, the current solution is to disassemble the motherboard of the electronic device for inspection or replacement. Not only is the process cumbersome, but the repair cost is also high. Moreover, in most cases, the motherboard is not damaged at all, but only the electrical connector socket is broken. However, since the electrical connector socket has been plugged or soldered to the motherboard (circuit board) before leaving the factory, the undamaged motherboard must also be replaced, resulting in a huge waste.

[0008] Furthermore, because conventional electrical connector sockets are already plugged into or soldered onto the motherboard (circuit board) at the factory, another disadvantage is that they are typically installed at the centerline of the electronic device. For example, a laptop computer, as shown in FIG7 , is installed at the centerline (C) of the computer body 50 . Consequently, for computers of varying thicknesses or specifications, motherboard electrical connector sockets must be manufactured to match their centerlines (C). Therefore, precision is required. Otherwise, after the motherboard is installed, the electrical connector socket will often not be located on the centerline (C) of the computer body 50 , causing significant inconvenience.

[0009] Therefore, how to develop an electrical connector that can improve the problems encountered in the prior art is a problem to be solved by the present invention. Summary of the Invention

[0010] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a detachable socket for a USB electrical connector that is easy to repair. The socket has the functions of convenient repair, environmental protection and reduced repair costs. The USB electrical connector socket can be accurately located at the center of the electronic device. The technical solution adopted by the present invention to solve its technical problem is: A detachable receptacle for a USB electrical connector that is easy to maintain comprises: a detachable unit including a first insulating package body, a tongue piece provided on a front end surface of the first insulating package body, an outer periphery of the tongue piece being covered by a metal shell to form an insertion port, and a shielding cover provided on the metal shell;

[0011] The rear end of the first insulating package body forms a vertical surface, and a protruding plate is extended outward in a horizontal direction from the vertical surface. The upper and lower surfaces of the protruding plate are provided with a plurality of arranged conductive gold fingers (Connecting Finger), and the vertical surface is provided with a first connecting portion on both sides of the protruding plate; and a fixing unit is directly fixed on the circuit board or the transmission cable, which includes a second insulating package body, the front end surface of the second insulating package body is provided with a plurality of arranged conductive terminals relative to the conductive gold fingers of the protruding plate, and the front end surface of the second insulating package body is provided on both sides of the conductive terminal. A second coupling portion is provided at the position of the first coupling portion, which can guide and fit together with the first coupling portion, so that the detachable unit and the fixed unit fit together to form a USB electrical connector socket, and the conductive terminals of the fixed unit of the USB electrical connector socket extend rearwardly from the rear end of the second insulating package body to form a joint portion that can be electrically connected to the transmission cable. The fixed unit of the USB electrical connector socket is fixedly connected to the transmission cable, so that the three form a transmission device; accordingly, when the detachable unit fails or is damaged, it can be independently withdrawn from the circuit board or transmission cable without the need to disassemble or replace the circuit board or transmission cable.

[0012] According to the aforementioned features, in a feasible embodiment, the first coupling portion may be in the form of a coupling hole, and the second coupling portion may be in the form of a coupling protrusion that can be embedded in the coupling hole, and the two may fit tightly together.

[0013] According to the aforementioned features, in another feasible embodiment, the first coupling portion may be in the form of a coupling boss, and the second coupling portion may be in the form of a coupling hole for the coupling boss to be embedded, and the two may fit tightly together.

[0014] According to the aforementioned features, the coupling hole may include a circular hole, a rectangular hole or any geometric hole, and the coupling protrusion may correspondingly include a circular protrusion, a rectangular protrusion or a corresponding geometric protrusion.

[0015] According to the aforementioned features, the USB electrical connector socket may include Type-C electrical connector specifications.

[0016] According to the aforementioned features, in a feasible embodiment, the conductive terminals of the fixing unit extend backward out of the rear end of the second insulating package to form a plurality of conductive pins that can be plugged into or soldered to a circuit board.

[0017] According to the aforementioned features, in another feasible embodiment, the conductive terminal of the fixing unit extends backward out of the rear end of the second insulating package to form a joint portion that can be electrically connected to the transmission cable.

[0018] Therefore, the present invention utilizes the aforementioned technical means to designate the most easily damaged portion of the USB electrical connector receptacle as a detachable independent unit. This makes maintenance extremely convenient. Only the detachable portion needs to be removed and replaced without touching the motherboard. This not only saves time and convenience, but also avoids wasting resources, is environmentally friendly, and reduces maintenance costs.

[0019] The beneficial effects of the present invention are that it is convenient to maintain; it is environmentally friendly and reduces maintenance costs; and its USB electrical connector socket can be accurately located at the center of the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details herein may be modified and altered based on different perspectives and applications without departing from the spirit of the present invention.

[0036] First, see Figures 4A to 5B As shown, the present invention discloses a detachable receptacle for a USB electrical connector that facilitates maintenance. A first feasible embodiment thereof comprises: a detachable unit 30 including a first insulating package body 31, a tongue 36 being provided on a front end surface of the first insulating package body 31. The outer periphery of the tongue 36 is covered by a metal shell to form an insertion port 35, and a shielding cover 34 is provided on the metal shell. However, the above structure is prior art for USB electrical connectors and is not the subject of the present invention, and thus will not be described in detail.

[0037] 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 extends horizontally outward 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 fingers) 321, and the vertical surface is provided with first connecting portions 33 on both sides of the protruding plate 32.

[0038] The fixing unit 40 is directly fixed to the circuit board 20 or the transmission cable 70. It includes a second insulating package 41. A plurality of conductive terminals 42 are arranged on the front surface of the second insulating package 41, corresponding to the conductive fingers 321 of the protruding plate 32. Second engaging portions 43 are also provided on the front surface of the second insulating package 41, on either side of the conductive terminals 42, corresponding to the first engaging portions 32, to guide and engage with the first engaging portions 32. This allows the detachable unit 30 and the fixing unit 40 to be interlocked to form a USB electrical connector receptacle 50. In the event of a malfunction or damage, the detachable unit 30 can be independently removed from the circuit board 20 or transmission cable 44 without having to disassemble or replace the circuit board 20 or transmission cable 44. In this embodiment, the USB electrical connector receptacle 50 may be a Type-C electrical connector, but is not limited thereto.

[0039] like Figures 4A to 5B As shown, in the first feasible embodiment of the present invention, the first coupling portion 33 can be in the form of a coupling hole 33a, and the second coupling portion 43 can 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 together.

[0040] Please continue reading Figure 6A As shown, the second feasible embodiment of the present invention has the same structure as the first embodiment and is represented by the same figure number, and the only difference is that: the first coupling portion 33 can be in the form of a coupling protrusion 33b, and the second coupling portion 43 relatively presents a coupling hole 43b for the coupling protrusion 33b to be embedded in, and the two can fit tightly together.

[0041] The coupling holes 33a or 43b disclosed in the first and second embodiments are circular holes, but are not limited thereto. Figure 6B As shown, 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 43 can be set to a rectangular protrusion 43c or a corresponding geometric protrusion.

[0042] Please continue reading Figures 7A to 8B As shown in FIG. 1 , a reference diagram of the USB electrical connector socket 50 of the present invention is shown in FIG. 1 , which shows the state of use of the electronic device 60. The electronic device 60 may be a laptop computer, but is not limited thereto. The conductive terminals 42 of the fixing unit 40 of the USB electrical connector socket 50 extend backwards out of the rear end of the second insulating package 41 to form a plurality of conductive pins 421 that can be plugged into or soldered to the circuit board (mainboard) 20. Figure 8A As shown, in this embodiment, the fixing unit 40 of the USB electrical connector socket 50 is plugged into or soldered onto the circuit board (mainboard) 20, but the detachable unit 30 is not fixed onto the circuit board (mainboard) 20. Therefore, during installation, the plug-in port 35 of the detachable unit 30 can be aligned with the center line (C) of the electronic device (laptop computer) 60, that is, at the connection port 61 position which is 1 / 2 of the height (H) of the laptop computer. Then, a support member or support pad 63 of a predetermined height is pre-set on the bottom shell 62 of the electronic device 60. In this way, the plug-in port 35 of the USB electrical connector socket 50 must be accurately located at the center line (C) of the electronic device (laptop computer) 60 without any error.

[0043] Please continue reading Figure 9 As shown, in another possible embodiment, the conductive terminals 42 of the fixed unit 40 of the USB electrical connector receptacle 50 extend rearwardly beyond the rear end of the second insulating package 41 to form a joint 44 that can be electrically connected to the transmission cable 70. In this embodiment, the fixed unit 40 of the USB electrical connector receptacle 50 is fixed to the transmission cable 70, forming a transmission device 70A having the fixed unit 40. However, the detachable unit 30 is not fixed to the transmission cable 70. It only tightly fits with the fixed unit 40 to form the USB electrical connector receptacle 50. In other words, the detachable unit 30 is designed as a detachable independent unit that can be separated from the transmission device 70A and replaced.

[0044] Because the female receptacle of a USB Type-C connector has a smaller interface, and the male and female terminals within it mate with each other flatly to form the electrical connection, they have a weak structural strength and are easily damaged by repeated plugging and unplugging. This means the tongue of a traditional connector is the most vulnerable part. Damage to this tongue alone requires the entire circuit board or transmission cable to be removed for repair or replacement, a cumbersome process and high repair costs. Sometimes, even the intact motherboard needs to be replaced, resulting in significant waste.

[0045] Therefore, the present invention utilizes the aforementioned technical means to configure the most easily damaged portion of the USB electrical connector receptacle 50 into a detachable independent unit. This makes maintenance very convenient. Only the detachable unit 30 needs to be replaced without touching the mainboard. This not only saves time and convenience but also avoids wasting resources, is environmentally friendly, and reduces maintenance costs.

[0046] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
