## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims priority of Chinese Patent Application No. 201210073740.9, filed on Mar. 20, 2012.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a plugging device, more particularly to a plugging device that is used to plug or unplug an electronic component into or from a socket electrical connector.
2. Description of the Related Art
Currently existing portable electronic apparatus, such as a notebook computer, a tablet computer, etc., is designed to be thin and light. This sort of electronic apparatus has to accommodate various types of electronic components with different functions within a limited space. Thus, it is difficult to assemble or disassemble each electronic component to or from the narrow limited space of the electronic apparatus.
For example, to mount a hard disk drive in an accommodation groove in a bottom end of a housing of a notebook computer, a worker must first insert the hard disk into the accommodation groove via a downward opening thereof, and then push the hard disk drive to move laterally so as to plug a plug electrical connector of the hard disk drive into a socket electrical connector inside the housing. Because the accommodation groove has a limited space, and the hard disk drive has no appropriate press structure, when the worker pushes the hard disk drive laterally inside the accommodation groove, he cannot exert a uniform force on the hard disk drive so that the plug electrical connector of the hard disk cannot be accurately plugged into the socket electrical connector. Moreover, if it is desired to remove the plug electrical connector from the socket electrical connector, the worker needs the aid of a tool to push the hard disk drive so as to separate the plug electrical connector from the socket electrical connector.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide a plugging device that has a simple structure and that is easy to assemble and disassemble.
Another object of the present invention is to provide a plugging device that is easy and simple to operate so that convenience and efficiency of plugging and unplugging an electronic component can be effectively enhanced to thereby reduce the operation time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The above-mentioned and other technical contents, features, and effects of this invention will be clearly presented from the following detailed description of one preferred embodiment in coordination with the reference drawings. Through description of the concrete implementation method, the technical means employed and the effectiveness to achieve the predetermined purposes of the present invention will be thoroughly and concretely understood. However, the enclosed drawings are used for reference and description only, and are not used for limiting the present invention.
Referring to FIGS. 1 and 2, a plugging device 300 according to the preferred embodiment of this invention is adapted to be disposed inside a portable electronic apparatus, such as a notebook computer or a tablet computer. The plugging device 300 is adapted to move an electronic component 1 so that a plug electrical connector 11 of the electronic component 1 is plugged into a socket electrical connector 21 of a circuit board 2. In this embodiment, the electronic component 1 is exemplified as a hard disk drive, and the circuit board 2 is exemplified as a motherboard mounted in a housing of the portable electronic apparatus. However, the electronic component 1 may also be an optical disc drive.
The plugging device 300 comprises a supporting frame 3, at least one slide member 4, and an operating member 5. The supporting frame 3 is disposed on the circuit board 2, and includes a front end 31, a rear end 32, and two side plates 33 disposed between the front and rear ends 31, 32. The slide member 4 is connected to one side of the electronic component 1, and is connected slidably to a corresponding one of the side plates 33. The operating member 5 includes an operating rod 51, and at least one lever 52 extending from the operating rod 51. The lever 52 includes a fulcrum portion 521 pivoted to the corresponding side plate 33, and a resistance portion 522 connected to the slide member 4. Through the disposition of the supporting frame 3, the slide member 4 and the operating member 5, the overall structure of the plugging device 300 is simple and is easy to assemble and disassemble.
When the operating member 5 is pivoted about the fulcrum portion 521 in a clockwise direction (V) (see FIG. 11), the slide member 4 and the electronic component 1 is pushed to move slidably along a forward direction (I) (see FIG. 12) relative to the supporting frame 3 so as to plug the plug electrical connector 11 into the socket electrical connector 21. When the operating member 5 is pivoted about the fulcrum portion 521 in a counterclockwise direction (VI) (see FIG. 14), the slide member 4 and the electronic component 1 is pushed to move slidably along a rearward direction (II) (see FIG. 15) relative to the supporting frame 3 so as to unplug the plug electrical connector 11 from the socket electrical connector 21. By pivoting the operating member 5 to push the slide member 4 and the electronic component 1 to move slidably relative to the supporting frame 3, the plug electrical connector 11 can be plugged into or unplugged from the socket electrical connector 21. Hence, the operation of the present invention is easy and simple, so that convenience and efficiency of plugging and unplugging the plug electrical connector 11 into and from the socket electrical connector 21 can be effectively enhanced, thereby reducing the operation time.
Below is a description of the detailed structure of the plugging device 300 and the connection and mode of operation between the plugging device 300 and the electronic component 1.
With reference to FIGS. 1 and 2, in this embodiment, the supporting frame 3 is fixed to the circuit board 2, for example, by using a screw-fastening method. The supporting frame 3 defines an accommodation space 34 having an opening 341 that faces upward. The slide member 4 and the electronic component 1 are mounted removably in the accommodation space 34 through the opening 341. The front end 31 of the supporting frame 3 is formed with a front opening 311 communicating with the accommodation space 34. The socket electrical connector 21 of the circuit board 2 extends partially into the accommodation space 34 through the front opening 311 for mating with the plug electrical connector 11 of the electronic component 1. It is worth to mention that, although the supporting frame 3 is exemplified as being fixed to the circuit board 2 in this embodiment, the supporting frame 3 may be directly fixed to a housing of a portable electronic apparatus.
In this embodiment, the plugging device 300 comprises two slide members 4 connected respectively to two opposite sides of the electronic component 1. The slide members 4 are connected slidably and respectively to inner surfaces of the side plates 33. The operating member 5 includes two levers 52 extending respectively and transversely from two opposite ends of the operating rod 51 along a same direction. Each of the levers 52 includes a fulcrum portion 521 connected pivotally to a respective side plate 33, and a resistance portion 522 connected to a respective slide member 4. Through the two slide members 4, the operating member 5 can exert a uniform force on the electronic component 1 to slide the same so that the plug electrical connector 11 of the electronic component 1 can accurately and stably plugged into or unplugged from the socket electrical connector 21 of the circuit board 2. It is worth to mention that the number of the slide member 4 and the number of the lever 52 of the operating member 5 may be one, respectively.
Each side plate 33 of the supporting frame 3 has a pivot hole 331 formed in the center thereof. The operating member 5 has a substantially inverted U-shaped cross section. Each lever 52 of the operating member 5 further includes a lever body 520 connected to the operating rod 51. In this embodiment, the lever body 520 is integrally connected as one piece with the operating rod 51. The fulcrum portion 521 has a cylindrical shape, and projects from an outer surface of the lever body 520. To connect pivotally the levers 52 to the respective side plates 33 of the connecting frame 3, the lever bodies 520 of the levers 52 are pressed toward each other so as to deform, and are then inserted into the accommodation space 34 through the opening 341 such that the fulcrum portions 521 of the levers 52 are registered respectively with the pivot holes 331. The lever bodies 520 are then released from being pressed to restore to their normal positions and to insert the fulcrum portions 521 into the respective pivot holes 331. Hence, the levers 52 are easily and quickly connected pivotably to the side plates 33 of the supporting frame 3.
To prevent removal of the fulcrum portions 521 from the respective pivot holes 331 during pivoting movement of the operating member 5 about the fulcrum portions 521 relative to the side plates 33, in this embodiment, the length of each fulcrum portion 521 is larger than the thickness of the respective side plate 33, so that each fulcrum portion 521 can extend through the respective pivot hole 331 and partially protrude from an outer surface of the respective side plate 33. Further, each lever 52 further includes a stop protrusion 523 projecting from an outer periphery of a respective fulcrum portion 521 and spaced apart from the lever body 520. The stop protrusion 523 is abuttable against the outer surface of the respective side plate 33 so as to interfere with the same, so that removal of the fulcrum portions 521 from the respective pivot holes 331 can be prevented during pivoting movement of the operating member 5.
Concretely speaking, the pivot hole 331 of each side plate 33 includes a first hole portion 332, and a second hole portion 333 communicating with one side of the first hole portion 332. The first hole portion 333 has a shape matching that of the fulcrum portion 521 to receive the fulcrum portion 521 therethrough. The second hole portion 333 has a shape matching that of the stop protrusion 523 to receive the stop protrusion 523 therethrough. When the fulcrum portion 521 and the stop protrusion 523 of each lever 52 are brought to register with the first hole portion 332 and the second hole portion 333 of the respective side plate 33, the fulcrum portion 521 and the stop protrusion 523 can extend out of the outer surface or retract into the inner surface of the corresponding side plate 33 through the first and second hole portions 332, 333, respectively. As such, the stop protrusion 523 of each lever can be ensured to maintain interference with the corresponding side plate 33 when it is pivoted to other angular positions. Hence, removal of the fulcrum portions 521 from the respective pivot holes 331 can be prevented.
Each of the slide members 4 is formed with a pivot notch 41 in the center thereof. The resistance portion 522 of each lever 52 has a cylindrical shape, and projects from an inner surface of the lever body 520. The resistance portion 522 is connected rotatably to the pivot notch 41. Through this, during pivoting movement of the operating member 5 about the fulcrum portions 521 relative to the side plates 33, through the engaging relations between the resistance portions 522 of the levers 52 and the pivot notches 41 of the respective slide members 4, the slide members 4 are pushed simultaneously so that the slide members 4 can move the electronic component 1 to slide therealong. Further, the pivot notch 41 has a downward opening 411. During assembly, the downward openings 411 of the pivot notches 41 are brought to align with the resistance portions 522 of the levers 52, after which the levers 52 are moved downward so as to extend the resistance portions 522 into the pivot notches 41 through the downward openings 411 thereof, thereby assembling the slide members 4 to the levers 52. Therefore, convenience of assembly between the slide members 4 and the levers 52 can be enhanced.
In this embodiment, the operating rod 51 and the resistance portions 522 are disposed on two opposite sides of the fulcrum portions 521. That is, the fulcrum portions 521 are disposed between the operating rod 51 and the resistance portions 522. When the operating rod 51 is pushed rearward, the operating member 5 pivots about the fulcrum portions 521 in the clockwise direction (V) (see FIG. 11), so that the resistance portions 522 of the levers 52 push the slide members 4 to slide along the forward direction (I) (see FIG. 12) relative to the supporting frame 3. When the operating rod 51 is pushed forward, the operating member pivots about the fulcrum portions 521 in the counterclockwise direction (VI) (see FIG. 14), so that the resistance portions 522 push the slide members 4 to slide along the rearward direction (II) (see FIG. 15) relative to the supporting frame 3.
It is worth to mention that, coping with the different specifications and sizes of the electronic components 1, the resistance portions 522 may be disposed above the fulcrum portions 521. That is, each resistance portion 522 may be disposed between the operating rod 51 and the corresponding fulcrum portion 521 to form another type of lever structure. Through the aforesaid configuration, when the operating member is pivoted in the clockwise direction (V), the resistance portions 522 will push the slide members 4 to slide along the rearward direction (II) relative to the supporting frame 3. When the operating member 5 is pivoted about the fulcrum portions 521 in the counterclockwise direction (VI), the resistance portions 522 will push the slide members 4 to slide along the forward direction (I) relative to the supporting frame 3.
More concretely speaking, in this embodiment, each of the two opposite sides of the electronic component 1 is formed with two engaging holes 12 spaced apart in a front-rear direction. Each slide member 4 includes two engaging studs 42 that are provided on an inner surface thereof. The engaging studs 42 are disposed respectively on two opposite sides of the pivot notch 41 to engage the engaging holes 12, respectively. Through the aforesaid structural configuration, when the operating member 5 pushes the slide members 4 to slide along the forward direction (I) or the rearward direction (II), front or rear end of each slide member 4 will not warp relative to the electronic component 1, so that the slide members 4 can be connected stably to the electronic component 1 and can stably move the electronic component 1 to slide therealong.
Each slide member 4 further includes two elongate slide grooves 43 formed in an outer surface thereof and disposed respectively on the two opposite sides of the pivot notch 41. Each elongate slide groove 43 extends in a front-rear direction. Each side plate 33 includes two guide protrusions 334 protruding from the inner surface thereof and disposed respectively on front and rear sides of the pivot hole 331. The guide protrusions 334 of each side plate 33 are connected slidably and respectively to the elongate slide grooves 43 of the respective slide member 4. Through the aforesaid structural configuration, when the operating member 5 pushes the slide members 4 to slide along the forward direction (I) or the rearward direction (II), each slide member 4 can slide stably relative to the respective side plate 33, and the front or rear end of each slide member 4 will not warp relative to the electronic component 1, so that the slide members 4 can be connected slidably, stably and respectively to the side plates 33 and can move the electronic component 1 to slide therealong.
Moreover, a groove wall of each elongate slide groove 43 is formed with a cutout 431. Each guide protrusion 334 extends into a respective elongate slide groove 43 through the cutout 431. When the slide members 4 are moved downward and assembled to the resistance portions 522 of the levers 52, each guide protrusion 334 extends simultaneously into the respective elongate slide groove 43 through the cutout 431. As such, convenience of assembly among the slide members 4, the operating member 5 and the side plates 33 can be enhanced. It is worth to mention that the number of the elongate slide groove 43 of each slide member 4 and the number of the guide protrusion 334 of each side plate 33 may be one, respectively. The effect of guiding the slide members 4 to slide along the forward direction (I) or the rearward direction (II) can be similarly achieved.
As shown in FIGS. 3 to 5, to assemble the plugging device 300 and the electronic component 1 (see FIG. 2), the lever bodies 520 of the levers 52 are first pressed toward each other, after which the operating member 5 is moved downward so that the levers 52 extend into the accommodation space 34 through the opening 341 and the fulcrum portions 521 and the stop protrusions 523 of the levers 52 are registered with the first hole portions 332 and the second hole portions 333 of the pivot holes 331, respectively. Then, the lever bodies 520 are released from being pressed so that the fulcrum portions 521 and the stop protrusions 523 extend through the first hole portions 332 and the second hole portions 333, respectively, and out of the outer surfaces of the side plates 33. At this time, the operating member 5 is assembled to the side plates 33 of the supporting frame 3.
As shown in FIGS. 6 and 7, the two slide members 4 are respectively assembled to the two opposite sides of the electronic component 1 such that the engaging studs 42 (see FIG. 2) of each slide member 4 are engaged to the engaging holes 12 (see FIG. 2) in the corresponding side of the electronic component 1. Subsequently, an assembly of the slide members 4 and the electronic component 1 is disposed between the levers 52 of the operating member 5 such that the downward openings 411 of the pivot notches 41 are aligned with the respective resistance portions 522 and the cutouts 431 of the elongate slide grooves 43 are aligned with the respective guide protrusions 334.
As shown in FIGS. 8 to 10, the assembly of the slide members 4 and the electronic component 1 is moved downward so as to be disposed in the accommodation space 34 through the opening 341. When the resistance portions 522 of the levers 52 extend into the pivot notches 41 through the downward openings 411 to engage the same, and the guide protrusions 334 extend into the respective elongate slide grooves 43 through the cutouts 431, the slide members 4 are simultaneously assembled to the levers 52 of the operating member 5 and the side plates 33 of the supporting frame 3. At this time, the assembly between the plugging device 300 and the electronic component 1 is completed.
As shown in FIGS. 10 to 12, to plug the plug electrical connector 11 of the electronic component 1 into the socket electrical connector 21 of the circuit board 2, the operating rod 51 of the operating member 5 is pushed rearward so that the operating member 5 pivots about the fulcrum portions 521 in the clockwise direction (V). The resistance portions 522 of the levers 52 will push the slide members 4 to slide along the forward direction (I) (see FIG. 12) relative to the supporting frame 3. The slide members 4, in turn, move the electronic component 1 to slide therealong so that the plug electrical connector 11 approaches the socket electrical connector 21. When the operating member 5 is pivoted into the accommodation space 34 to a collapsed position, as shown in FIG. 12, the plug electrical connector 11 of the electronic component 1 is plugged into the socket electrical connector 21. At this time, the plug electrical connector 11 and the socket electrical connector 21 are coupled electrically to each other to transmit an electrical signal.
As shown in FIGS. 1, 2 and 11, to stably fix the electronic component 1 in a plugging position, in this embodiment, each side plate 33 further has a positioning hole 335 proximate to the rear end 32 thereof, and the operating rod 51 includes two resilient plates 511 provided respectively on two opposite ends thereof, and two engaging pieces 512 projecting respectively from outer sides of the resilient plates 511. Each of the engaging pieces 512 is engaged removably to the positioning hole 335 in the respective side plate 33. When the operating member 5 is pivoted to the collapsed position shown in FIG. 12, the engaging pieces 512 of the operating rod 51 will engage the respective positioning holes 335 so that the operating member 5 is engaged stably to the side plates 33, thereby preventing removal of the engaging pieces 512 from the respective positioning holes 335 when the portable electronic apparatus falls off or vibrates. Hence, the operating member 5 can stably fix the electronic component 1 in the plugging position. It is worth to mention that the number of the engaging piece 512 of the operating member 5 and the number of the positioning hole 335 in the supporting frame 3 can be one, respectively. The effect of fixing the operating member 5 to the side plates 33 can be similarly achieved.
As shown in FIGS. 13 to 15, to unplug the plug electrical connector 11 of the electronic component 1 from the socket electrical connector 21 of the circuit board 2, the two engaging pieces 512 are pushed inward from the outer sides of the respective positioning holes 335 to deform the resilient plates 511 that causes the resilient plates 511 to move toward each other and to disengage from the positioning holes 335, thereby disengaging the operating member 5 from the side plates 33. At this time, the operating rod 51 of the operating member 5 is pushed upward, and the operating member 5 pivots about the fulcrum portions 521 in the counterclockwise direction (VI). During pivoting movement of the levers 52, the resistance portions 522 of the levers 52 will push the slide members 4 to slide along the rearward direction (II) (see FIG. 15) relative to the supporting frame 3. The slide members 4, in turn, move the electronic component 1 to slide therealong so that the plug electrical connector 11 is moved gradually away from the socket electrical connector 21. When the operating member 5 is pivoted to a position, as shown in FIG. 15, the plug electrical connector 11 of the electronic component 1 is unplugged from the socket electrical connector 21.
In sum, by pushing the operating rod 51 of the operating member 5 to pivot the two levers 52, the resistance portions 522 of the levers 52 can exert uniform pushing force on the two opposite sides of the electronic component 1 through the slide members 4 to slide the electronic component 1 during pivoting movement of the levers 52, so that the plug electrical connector 11 of the electronic component 1 can accurately and stably plug into or unplug from the socket electrical connector 21 of the circuit board 2. Further, by pivoting the operating member 5 along the clockwise direction (V) or the counterclockwise direction (VI), the slide members 4 can move the electronic component 1 to slide therealong so as to plug or unplug the plug electrical connector 11 of the electronic component 1 into or from the socket electrical connector 21 of the circuit board 2. Hence, the operation of the plugging device 300 of the present invention is easy and simple, so that the convenience and efficiency of plugging or unplugging the electronic component 1 can be enhanced to thereby reduce the operation time. Moreover, through the disposition of the supporting frame 3, the slide members 4 and the operating member 5, the overall structure of the plugging device 300 is simple and is easy to assemble and disassemble. Additionally, when the operating member 5 is in the collapsed position, the engaging pieces 512 of the operating rod 51 are engaged respectively to the positioning holes 335 so that the operating member 5 can be stably connected to the side plates 33. As such, the electronic component 1 can be stably fixed in the plugging position without the use of screws. Therefore, the objects of this invention can be served.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
