1 is a perspective view showing the appearance of a portable device having a removable connector according to an embodiment of the present invention, Figure 2 is a perspective view showing a path electrically connected inside the connector and the housing, Figure 3 is a hinge arm and 4 is a conceptual diagram illustrating the shape and coupling relationship of the hinge arm holder, and FIG. 4 is a reference diagram illustrating a shape of a portable device having a detachable connector according to an exemplary embodiment of the present invention.

1 (a) shows a state in which the connector 100 and the housing 200 are separated, and FIG. 1 (b) shows a state in which the connector 100 is coupled with the housing 200 to rotate 360 °. .

A portable device having a detachable connector according to the present invention comprises a detachable connector 100 and a housing 200 as shown in FIG.

As shown in (a) of FIG. 1, the connector 100 has a rectangular cross section when viewed from above and has a long shape in the vertical direction. Meanwhile, four rows of terminals 110 are provided inside the upper end of the connector 100, and cylindrical hinge arms 120 protrude from lower ends of both sides.

In this case, the four lines of terminals 110 correspond to the common collector voltage (VCC), the ground (GND), the DATA +, and the DATA-, respectively. When the connector 110 is inserted into the slot provided in the computer as described below, The terminal electrically connects the circuit 250 inside the housing 200 and the slot. Since the connector 100 has two data terminals, it is used for serial communication. In the example of FIG. 1, four terminals are arranged side by side on the inner side of the upper side of the connector 100, but two on one side thereof. It may be arranged so as to face each other on two sides.

On the other hand, it can be seen that each of the two rows of conductive rotation patterns 130 are formed on the outer circumferential surface of the hinge arm 120 protruding in a cylindrical shape, the conductive rotation pattern 130 is a hinge arm 120 A circle is formed along the outer circumference.

At this time, as shown in (a) of FIG. 2, the conductive rotation pattern 130 is connected to the terminal 110 of the four lines through the connector 100 one by one. Since the conductive rotation pattern 130 is formed on the outer circumferential surface of both hinge arms 120, four lines are formed in total, so that the conductive rotation pattern 130 is connected to the terminal 110 of four lines corresponding to VCC, GND, DATA +, and DATA- in a one-to-one manner. do.

The conductive rotation pattern 130 may be manufactured in a ring shape of a conductive metal material and may be fitted along the outer circumferential surface of the hinge arm 120. However, in consideration of manufacturing cost and durability, the conductive rotation pattern 130 may be etched on the outer circumferential surface of the hinge arm 120. Do.

Meanwhile, the conductive rotation pattern 130 is electrically connected to the terminal 110 along the inside of the hinge arm 120, wherein the conductive rotation pattern 130 and the terminal 110 are connected to both ends of the electric wire. It may be connected by soldering or may be electrically connected by a separate printed circuit board (PCB) pattern.

As shown in (a) of FIG. 1, the housing 200 is formed by drilling a connector insertion space 210 at the top center thereof, as shown in (b) of FIG. 1. Is inserted into the connector insertion space 210. The expression that the space in which the connector 100 is inserted is formed by puncture means that a space enough to accommodate the connector 100 is formed through the front, rear, left, and right sides of the connector 100, As shown in (b) of FIG. 1, the connector 100 can rotate through the insertion space 210 with the connector hinge arm 120 as the rotation axis.

Meanwhile, cylindrical hinge arm holders 220 into which the hinge arm 120 is inserted are formed at both upper ends of the connector insertion space 210.

As shown in (a) of FIG. 1, it can be seen that the hinge arm holder 220 is perforated in a cylindrical shape in both upper and outer directions of the connector insertion space 210. As shown, the hinge arm 120 is inserted into the hinge arm holder 220 and rotated.

On the other hand, according to Figure 1 (a) is formed a guide opening portion 240 is cut off part of the hinge arm holder 220. When the housing 200 is made of an elastic plastic material, the hinge arm 120 is brought into close contact with the guide opening 240, and the guide opening 240 is opened by elasticity when the housing is pressed against the connector 100. The hinge arm 120 is inserted into the hinge arm holder 220.

On the contrary, when the connector 100 is separated from the housing 200, the connector 100 may be pulled out in the direction in which the guide opening 240 is formed.

On the other hand, the hinge arm 120 is preferably rounded in both directions of the guide opening 240, as shown in Figure 1 (a) to be easily removable.

Meanwhile, as shown in FIGS. 1A and 2B, a receptacle is positioned at a position corresponding to the conductive rotation pattern 130 along the inner circumferential surface of the hinge arm holder 220. Two terminals 230 are formed, respectively.

In this case, the position corresponding to the conductive rotation pattern 130 of the inner circumferential surface of the hinge arm holder 220 is the conductive rotation pattern 130 and the hinge arm holder when the hinge arm 120 is inserted into the hinge arm holder 220. (220) refers to a region in which the inner circumferential surface is in contact.

Meanwhile, the receptacle terminal 230 is preferably formed long along the inner circumferential surface of the hinge arm holder 220 in a ring shape in which the guide opening portion 240 is cut, and the hinge arm 120 of the connector 100 is the hinge arm holder. When inserted into the 220, the two rows of conductive rotation patterns 130 are in contact with each other in a one-to-one manner. On the other hand, unlike the conductive rotation pattern 130 must have a ring shape, the receptacle terminal 230 is a shape if the hinge arm 120 can maintain the electrical connection with the conductive rotation pattern 130 while rotating 360 ° This does not necessarily have to be ring-shaped.

This receptacle terminal 230 is electrically connected to the circuit 250 along the inside of the housing 200 as shown in FIG. The circuit 250 is generally manufactured by mounting a semiconductor chip on a PCB substrate and soldering it. The receptacle terminal 230 is directly soldered to a solder pad of the PCB substrate, or is connected to the PCB substrate through an electric wire. Can be connected.

According to this structure, when the hinge arm 120 of the connector 100 is inserted into the hinge arm holder 220 of the housing 200, the four-row terminal 110 provided inside the upper portion of the connector 100 is electrically conductive. It is electrically connected to the circuit 250 via the pattern 130 and the receptacle terminal 230. The electrical connection is maintained even while the connector 100 rotates 360 ° with the hinge arm 120 as the rotation axis.

At this time, since the hinge arm 120 rotates while being in contact with the inner circumferential surface of the hinge arm holder 220, the conductive rotation pattern 130 and the receptacle terminal 230 are damaged or detached despite the rotation of the connector 100. Not)

Meanwhile, as shown in FIG. 3, the hinge arm 120 and the hinge arm holder 220 are more firmly coupled and the conductive arm pattern 130 and the receptacle terminal 230 are prevented from shorting. Unevenness may be formed on the outer circumferential surface of the hinge arm 120 and the inner circumferential surface of the hinge arm holder 220.

According to the example illustrated in FIG. 3A, an etching portion 121 protruding from the outer circumferential surface of the hinge arm 120 is formed, and a recessed terminal seat 221 is formed on the inner circumferential surface of the hinge arm holder 220. .

The etching portion 121 illustrated in FIG. 3A protrudes at a constant height along the outer circumferential surface of the hinge arm 120, and any one of two rows of conductive rotation patterns 130 may be formed on the outer circumferential surface of the etching portion 121. Etched, the other one is etched in the non-protruding portion of the outer peripheral surface of the hinge arm (120).

On the contrary, any one of two receptacle terminals 230 is seated on the terminal seat 221 recessed on the inner circumferential surface of the hinge arm holder 220, and the other one is seated on the unrecessed portion of the inner circumferential surface of the hinge arm holder 220. do.

As a result, when the hinge arm holder 220 of the hinge arm 120 is inserted, the etching part 121 is inserted into the terminal seating part 221, so that the hinge arm 120 and the hinge arm holder 220 are accurately engaged with each other. In addition, the connector 100 can rotate, and the conductive rotation pattern 130 and the corresponding receptacle terminal 230 are exactly in one-to-one contact, so that the connector 100 is pushed to the left and right sides or is twisted. This can be maintained.

On the other hand, Figure 3 (b) on the contrary, the etching portion 121 is recessed, and the terminal seating portion 221 is shown in the form of protruding, but only the shape of the unevenness is not different from that described above.

FIG. 3C illustrates a shape in which the uneven edges of the etching part 121 and the terminal seating part 221 are rounded. According to the enlarged view of the right side of FIG. 3C, it can be seen that the corner of the terminal seating portion 221 is rounded.

As such, when the hinge arm holder 220 of the hinge arm 120 is inserted by rounding the uneven edges of the etching part 121 and the terminal seating part 221, the etching part 121 is inside the terminal seating part 221. As it can be easily inserted into the connector 100 and the housing 200 can be combined smoothly.

Figure 4 shows the shape of using a portable device having a removable connector having the structure as described above, when the user first combines the connector 100 and the housing 200 to insert the connector 100 into the slot, Electrical connection is made between the circuit 250 and the slot inside the housing 200.

Thereafter, the user can freely rotate the housing 200 by using the hinge arm 120 as a rotating shaft. In the example of FIG. 4, the user can bend it downward by 90 ° to contact the slot installation surface. The portable devices often have a long shape in the horizontal direction, so that they may be accidentally broken during use or slipped out of the slot, and this problem is solved when used in contact with the slot installation surface.

In addition, when the user wants to connect another portable device to the slot, only the housing 200 may be removed while the connector 100 is inserted into the slot, and the other housing 200 ′ may be connected to the connector 100. As the connector 100 and the housing 200 are separated, even if any of the connector 100 or the housing 200 is damaged, only the damaged part can be newly purchased and used, which is economical, and the connector 100 is inserted into the slot. Since only the housing 200 can be carried in a state, portability is further enhanced.

Hereinafter, a configuration of a portable device having a detachable connector according to this and third embodiments of the present invention will be described with reference to FIG. 5.

In this embodiment of the present invention shown in Figure 5 (a) is different from the embodiment described above, the hinge arm 120 is formed on the front and rear instead of the left and right sides of the connector 100, the connector insertion space ( 210 is also formed to be perforated to penetrate the upper side rather than the front and rear surfaces of the housing 200. Hinge arm holder 220 is also formed along the front and rear surfaces of the connector insertion space 210.

In addition, the guide opening 240 is formed on one side of the hinge arm holder 220, or the conductive rotation pattern 130 is formed on the outer circumferential surface of the hinge arm 120, two lines, respectively, corresponding to the inner circumferential surface of the hinge arm holder 220 The same is true in that the receptacle terminal 230 is formed in position.

In FIG. 5B, the hinge arm holder 120 ′ is formed in the lower left and right sides of the connector 100 and the upper side of the connector insertion space 210 of the housing 100 is formed. The hinge arm 220 'is formed to protrude. At this time, unlike the embodiment, the guide opening is not formed at one side of the hinge arm holder 120 ', and the hinge arm 220' is positioned at the left and right sides of the connector insertion space 210 as shown in FIG. It can be inserted into the hinge arm holder (120 ').
