3 is a schematic view showing the connection of the conductive joint of the tablet of FIG. 1 and the single-needle spring connector of the docking station.

1 is a schematic diagram of an electronic device in accordance with an embodiment of the present invention. Referring to FIG. 1 , an electronic device 10 of the embodiment includes a tablet computer. 100 and a docking station 200. The tablet 100 is detachably disposed on the docking station 200 to be used as a tablet or a notebook computer according to user requirements. The tablet 100 includes a first port 110. The docking station 200 includes a second port 210 corresponding to the first port 110. The tablet 100 and the docking station 200 are coupled to the second port 210 through the first port 110 for signal transmission.

In the present embodiment, the docking station 200 includes a USB 3.0 port 290. The user can insert an external device (not shown, such as an external hard disk or an external flash drive) that can conform to the USB 3.0 specification into the USB 3.0 port 290 of the docking station 200, so that the tablet 100 can pass through. The docking station 200 accesses information in the external device at a high speed.

The conventional electronic device transmits information by using a male and female connection port of 40 pins. Due to the small size of the stitches, when the conventional tablet is docked with the docking station, there is a slight offset between the male and female connectors. The pins can't be accurately aligned, and the signal is interrupted or distorted when the signal is transmitted, especially when the high-speed transmission is performed.

In the present embodiment, in order to avoid the above problem, the second port 210 includes a plurality of single-pin spring connectors 220. In the present embodiment, the second port 210 includes ten single-pin spring connectors 220, but a single pin The number of spring connectors 220 is not limited thereto. The signal transmission between the tablet computer 100 and the docking station 200 of the electronic device 10 of the embodiment is transmitted through the packet, so that the number of the transmission terminals in the first port 110 and the second port 210 can be reduced. Increase the size of the transmission terminal in a limited space, for example, replacing a conventional pin with a larger single pin The spring connector 220 provides tolerance for a high positional deviation between the tablet 100 and the docking station 200. Therefore, even if there is a slight misalignment between the tablet 100 and the docking station 200, stable data transfer can be performed.

In the ten single-pin spring connectors 220 of the embodiment, four pairs are used to transmit high-speed signals TX+, TX-, RX+, RX-, and the other two are used to transmit low-speed signals D+, D-, of course. The number of single-pin spring connectors 220 and the type of signals transmitted are not limited thereto, but if high-speed transmission is required between the tablet computer 100 and the docking station 200, the number of single-pin spring connectors 220 needs to be an even number.

It should be noted that the conductive outer terminal of the general single-pin spring connector contacts the metal housing on the side in line contact, and the signal is transmitted along the metal housing along the side of the conductive outer terminal in a minimum path. However, since the conductive outer terminal is pushed, a left-right offset condition may occur, so that the position of the metal housing contacting each side is different, causing a different signal transmission path, which may occur when a high-speed signal is transmitted. Distortion condition.

The single-needle spring connector 220 of the present embodiment can avoid the above problems by structural improvement. This will be described in detail below. 2 is a schematic view of a single needle spring connector of the docking station of the electronic device of FIG. 1. Referring to FIGS. 1 and 2 , each single-pin spring connector 220 includes a spring 230 , a conductive outer terminal 240 coupled to the spring 230 and protruding from the expansion base 200 , and a conductive inner terminal 250 contacting the conductive outer terminal 240 . . The conductive outer terminal 240 includes a base 242 and a top portion 244 protruding from the base 242. The base 242 contacts the conductive inner terminal 250, and a portion of the top portion 244 extends from the docking station 200. The conductive inner terminal 250 has a bent cantilever 252, The bent cantilever 252 contacts the side of the base 242 of the conductive outer terminal 240. The bent cantilever 252 is flexible to allow the conductive outer terminal 240 to remain in contact with the base 242 during movement up and down.

In this embodiment, since the contact area between the bent cantilever 252 of the conductive inner terminal 250 and the base 242 of the conductive outer terminal 240 is small, close to the point contact, the left and right offset occurs even when the conductive outer terminal 240 is pushed. In the condition, the sides of the base 242 of the conductive outer terminal 240 are in contact with the bent cantilever 252 of the conductive inner terminal 250, so that the path of the signal transmission can be uniform.

In addition, the second port 210 includes an insulative housing 260 that includes a plurality of cavities 262, a plurality of openings 264, and a plurality of side walls 266 that surround the opening 264, as shown in FIG. Single needle spring connector 220 and its surrounding insulative housing 260, therefore, only a single cavity 262 and a single opening 264 are shown in FIG. As shown in FIG. 2, the top 244 of the conductive outer terminal 240 extends beyond the corresponding opening 264 and is adapted to move along the corresponding side wall 266. In the present embodiment, the second port 210 is permeable to the height of the side wall 266 of the insulative housing 260 such that the top 244 of the conductive outer terminal 240 can be constrained to a straight up position as it moves along the side wall 266.

In addition, in the embodiment, the second connecting port 210 includes a plurality of first insulating blocks 270 and a plurality of second insulating blocks 280. As shown in FIG. 2, the conductive outer terminals to which the first insulating blocks 270 are connected Below the base 242 of the 240, the second insulating block 280 is respectively connected to the position of the insulating housing 260 corresponding to the first insulating block 270, and the first insulating block 270 and the second insulating block 280 are located at the spring 230. Both ends. When the conductive outer terminal 240 is depressed, the spring 230 is compressed such that the distance between the first insulating block 270 and the second insulating block 280 gradually approaches until the first insulating block 270 touches the second insulating block. At block 280, the spring 230 can no longer continue to compress, at which point the conductive outer terminal 240 moves to the lowest position.

Thereafter, when the conductive outer terminal 240 is not pressurized, the spring 230 recovers and lifts the conductive outer terminal 240. In the present embodiment, the cross-sectional area of the base 242 of each of the conductive outer terminals 240 is greater than the cross-sectional area of the top 244 such that there is a differential surface 246 between the base 242 and the top 244, and the insulative housing 260 includes these A plurality of stop faces 268 of the step faces 246. When the step surface 246 of the conductive outer terminal 240 contacts the stop surface 268 of the insulating case 260, the conductive outer terminal 240 cannot be further raised. At this time, the conductive outer terminal 240 is located at the uppermost position. Therefore, in the present embodiment, the conductive outer terminal 240 is restricted to a certain range of movement through the above mechanism.

In addition, in the present embodiment, since the conductive tab 112 of the first port 110 (see FIG. 3) is slightly recessed in the tablet 100, after the tablet 100 is connected to the docking station 200, the top 244 of the conductive outer terminal 240 is 244. The protrusion base 200 is still slightly protruded. Therefore, when the conductive outer terminal 240 is not pressed, the distance between the first insulation block 270 and the corresponding second insulation block 280 is smaller than that of the conductive outer terminal 240. The top 244 protrudes from the length of the insulative housing 260. That is, in the present embodiment, the distance between the first insulating block 270 and the second insulating block 280 defines the amount of downward movement of the conductive outer terminal 240. Of course, in other embodiments, the conductive tab 112 of the first port 110 may also be flush with the housing of the tablet 100. In this case, the first insulating block 270 and the corresponding second insulating block 280 the distance between It will be equal to the length 244 of the conductive outer terminal 240 protruding from the length of the insulative housing 260.

3 is a schematic view showing the connection of the conductive joint of the tablet of FIG. 1 and the single-needle spring connector of the docking station. Referring to FIG. 1 and FIG. 3, in order to avoid confusing the lines, only the appearance of the connection of the conductive joint 112 and the single-pin spring connector 220 is specifically shown in FIG. 3, and the tablet 100 and the docking station are hidden. The outline of 200. In fact, these conductive tabs 112 will be located within the tablet 100, and the single-pin spring connector 220 will protrude slightly from the docking station 200.

When the tablet 100 is docked with the docking station 200, the conductive connector 112 of the tablet 100 pushes and contacts the conductive outer terminal 240 of the single-pin spring connector 220 to electrically connect the tablet 100 to the docking station 200. In addition, the conductive joints 112 and the conductive inner terminals 250 of the single-pin spring connector 220 are respectively connected to a circuit board (not shown) located inside the tablet 100 and the docking station 200.

The electronic device 10 of the present embodiment can stably transmit the high-speed signal of the USB 3.0 through the verification of the laboratory specified by the USB Association. In addition, compared to the conventional 40 conductive inner terminals, the connection has a lower production cost and a longer service life.

In summary, each stitch is used to transmit a single signal compared to the conventional 40-pin connection. In the electronic device of the present invention, the second connection of the docking station is a single-needle spring. The connector is in the form of a first connection to the tablet and the signal is transmitted in a packet. Since the single-pin spring connector is larger in size than conventional pins, it provides a higher tolerance for positional deviation between the tablet and the docking station, so that even if there is a tablet between the tablet and the docking station Stable data transfer is also possible in some micro-dislocations. In addition, the conductive outer terminal of the general single-needle spring connector contacts the metal housing on the side in the form of line contact, and the position of the metal housing contacting the side when the conductive outer terminal is offset may be different, The transmission path of the signal is relatively unclear, and distortion may occur when transmitting high-speed signals. In the electronic device created by the present invention, the single-pin spring connector directly contacts the conductive outer terminal through the conductive inner terminal in a point contact manner, thereby ensuring a signal transmission path to provide a stable high-speed signal transmission environment.
