Description
Technical Field
The present utility model relates to a universal serial bus device, and more particularly to a universal serial bus device with antistatic capability.
Background

For a further understanding of the objects, construction, features, and functions of the utility model, reference should be made to the following detailed description of the preferred embodiments.

The usb device 10 is preferably adapted to establish a wireless connection between a computer terminal (e.g., notebook computer or desktop computer, etc.) and an external device (e.g., wireless keyboard, wireless mouse, etc.), for performing related control operations (e.g., text input, cursor movement, etc.) on the computer terminal by the external device, as shown in fig. 1, 2, 3, and 4, the usb device 10 includes a base 12, a circuit board 14, a top cover 16, a plurality of solder joints 18 (e.g., soldering, four shown in fig. 3, but not limited thereto), a switch 20, and a button assembly 22. The circuit board 14 is disposed on the base 12 and has a front button end 24, a rear plugging end 26 and a ground wire 28, and the rear plugging end 26 is preferably in the form of a golden finger (but not limited thereto) as shown in fig. 2 for plugging into a connection port of a computer, which is common in the prior art for the plugging design of the usb device 10, and will not be repeated herein.
As shown in fig. 1 to 4, the upper cover 16 is disposed on the front button end 24 and has a button opening 30, a plurality of soldering points 18 are formed on the upper surface S1 of the front button end 24 and electrically connected to the ground wire 28 of the circuit board 14, the switch 20 can be used to control the wireless connection between the computer end and the external device and has a metal cover 21 and soldered to the plurality of soldering points 18, the button sleeve 22 is disposed on the front button end 24 and movably penetrates through the button opening 30 so that a user can subsequently trigger the switch 20 by pressing the button sleeve 22, and a first guiding hole 32 is formed at a position of the button sleeve 22 corresponding to the switch 20 to establish an esd guiding path in the upper cover 16, which is common in the related description of the circuit ground design of the circuit board 14 and is not repeated in the prior art.
Through the above design, if the esd event occurs when the esd event enters the usb device 10 from the button opening 30 of the upper cover 16, for example, the esd event E1 shown in fig. 1 enters from the upper side of the button opening 30, at this time, the esd event E1 entering from the button opening 30 is smoothly conducted to the ground line 28 of the circuit board 14 through the relatively short esd guide path established by the first guide hole 32 and the at least one solder 18 of the metal cover 21 and the plurality of solder 18 (that is, the metal cover 21 grounded through the solder 18 can generate the metal shielding protection effect on the switch 20), thereby generating the esd protection effect. Therefore, the utility model can effectively solve the problem that the electrostatic discharge enters from the button opening of the USB device to damage the electronic components (such as antenna, switch, etc.) in the USB device, thereby greatly improving the antistatic capacity and service life of the USB device.
It should be noted that, in order to enhance the bottom anti-static discharge capability of the usb device, the present utility model may further employ a configuration of bottom conductive foil, for example, as shown in fig. 2 and 4, the usb device 10 may further include a bottom conductive foil 34, the bottom conductive foil 34 may be formed on the lower surface S2 of the front button end 24 and electrically connected to the ground line 28, and the button set 22 is formed with a second guiding hole 36 corresponding to the bottom conductive foil 34 to establish another electrostatic discharge guiding path in the upper cover 16. Thus, if the esd E2 shown in fig. 1 enters the usb device 10 from the position below the button opening 30, the esd E2 is smoothly conducted to the ground line 28 of the circuit board 14 (i.e. the bottom conductive foil 34 can generate a metal shielding protection effect on the circuit board 14) through the relatively short electrostatic guiding path established by the second guiding hole 36 and the bottom conductive foil 34, so as to achieve the protection effect of the bottom electrostatic grounding of the usb device.
In practical applications, the present utility model may also employ an electrostatic grounding protection design for grounding the circuit board to the computer terminal for discharging, for example, please refer to fig. 2, 4, 5 and 6, fig. 5 is an internal assembly schematic diagram of the usb device 10 of fig. 1, and fig. 6 is a cross-sectional schematic diagram of the usb device 10 of fig. 1 along the section line A-A. As shown in fig. 2, 4, 5 and 6, the universal serial bus device 10 may further include a rear conductive foil 38, a metal shell 40 and a conductive member 42, where the rear conductive foil 38 is formed on the upper surface S1 adjacent to the rear plugging end 26 and the conductive foil 38 is electrically connected to the ground wire 28, the metal shell 40 is connected to the upper cover 16 and sleeved on the rear plugging end 26, the metal shell 40 is bent downward to form a contact piece 41 corresponding to the position of the rear conductive foil 38, the conductive member 42 may preferably be a bent conductive spring (but not limited to this), other conductive member configurations may be adopted, for example, a conductive block may be disposed in a manner of being clamped between the metal shell and the rear conductive foil, and the conductive member 42 is disposed on the rear conductive foil 38 (for example, but not limited to this), and abuts against the contact piece 41 (as shown in fig. 6), thereby, the electrostatic discharge (i.e. electrostatic discharge E1, E2) conducted to the ground wire 28 in the above embodiment may be further conducted to the computer through the conductive end of the conductive shell 38, the conductive member 42 and the conductive member 40 to establish a further electrostatic discharge path.
In addition, if the esd comes from above the usb device 10, the present utility model may also provide an anti-esd function by the above-mentioned design that the switch 20 has the metal cover 21 and the metal cover 21 is soldered to the soldering point 18 to be electrically connected to the ground terminal 28 of the circuit board 14, for example, as shown in fig. 1 and 6, the upper cover 16 has the light emitting hole 44 adjacent to the metal cover 21, and the usb device 10 may further include an indication light source 46 (preferably, but not limited to, a light emitting diode) disposed at a position corresponding to the light emitting hole 44 of the upper cover 16 and electrically connected to the circuit board 14 for emitting light to emit from the light emitting hole 44, thereby providing a light emitting indication function (such as indicating a wireless pairing condition of the usb device 10). In this configuration, the electrostatic discharge E3 entering the usb device 10 from the light exit hole 44 is smoothly conducted to the ground line 28 of the circuit board 14 through the relatively short electrostatic guiding path established by the light exit hole 44 and at least one of the solder points 18 of the metal cover 21 and the plurality of solder points 18, so as to achieve the protection effect of the electrostatic ground above the usb device.
It should be noted that, in order to prevent the electrostatic discharge entering from the button opening from being directly conducted to the antenna located on the front button end, the present utility model may employ a structure cladding design, for example, as shown in fig. 5, the usb device 10 may further include an antenna 48, the antenna 48 is mounted on the upper surface S1 of the front button end 24 to provide a wireless signal transceiving function, and the position of the button set 22 corresponding to the antenna 48 may further be formed with a cladding structure 23, the cladding structure 23 is looped around the antenna 48 to block the electrostatic discharge entering from the button opening 30 from being conducted to the antenna 48 (since the electrostatic discharge entering from the button opening 30 into the usb device 10 must bypass the cladding structure 23 before reaching the antenna 48, the surrounding configuration of the cladding structure 23 may generate the effect of blocking the electrostatic discharge).
In summary, the solder joint grounding design, the rear conductive foil design and the antenna cladding design according to the embodiments of the present utility model can be independently implemented or alternatively applied, so as to improve the design flexibility of the usb device in electrostatic grounding protection, for example, in the embodiment where the solder joint grounding design and the rear conductive foil design are omitted, the usb device of the present utility model can only use the antenna cladding design to generate the anti-esd effect of blocking the esd entering from the button opening, and other derivative variant embodiments (such as the embodiment where the solder joint grounding design or the rear conductive foil design is independently implemented, the embodiment where the solder joint grounding design and the antenna cladding design are only implemented) can be similarly omitted, and the description thereof will not be repeated herein.
Of course, the present utility model is capable of other various embodiments and its several details are capable of modification and variation in light of the present utility model by one skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
