USB card device {USB DEVICE HAVING CARD-SHAPED BODY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a USB apparatus, and more particularly to a USS apparatus having a card-shaped base.

Various storage media have been released in accordance with the increase in the removable storage media. For example, a stick type USB memory is typically used, and data is easily used through the USB terminal and is widely used.

Since the stick type USB memory is literally in the form of a stick, when it is carried in a pocket, it may be mixed with other objects, such that there is a risk of damage.

In addition, there is an advantage that the size is small in the form of a stick, but also has the disadvantage of a large risk of loss.

Therefore, in order to alleviate such drawbacks, Patent Publication No. 984137 and Publication No. 2010-0104340 propose a card type USB device, respectively.

According to these devices, there is an advantage that the convenience of portability can be increased by taking a structurally thin card form.

On the other hand, in the former case, it is difficult to take out the USB body from the mounting groove of the card, and it is rather difficult to handle by the connector. In the latter case, the memory function unit is rotatably coupled to the card function unit during use. There is a problem that it can be easily separated.

Accordingly, it is an object of the present invention to provide a USS device having a thin card-shaped base equipped with USS while being easy to handle.

Another object of the present invention is to provide a USB device that can be used in a stick easily separated from the card base for convenience.

According to the present invention, there is provided a card-shaped base having a mounting portion open at one side and surrounded by a support wall at one side thereof; And a USB unit in which the USB is detachably received and the elastic locking member is accommodated and fixed, and is inserted into the mounting portion of the base and slides. There is provided a card-shaped USB device in which a slide of the USB unit is stopped by a protrusion or the USB unit slides over the locking protrusion by elasticity of the locking member.

Preferably, the locking projection comprises: a first locking projection formed corresponding to a position at which the USB unit is completely inserted into the mounting portion; And second and third catching protrusions sequentially formed in a withdrawal direction corresponding to a position where the USB is exposed to the outside so as to be inserted into the USB port, wherein the catching member is formed in an area where the second and third catching protrusions are formed. The storage is seated.

In addition, preferably, the locking member includes a support part accommodated and fixed to the USB unit, and an elastic part elastically bent to the support part, and the elastic part includes a bar and a tip perpendicular thereto. The configured T-shaped locking piece protrudes, and the region formed by the second and third locking protrusions has a size and a shape corresponding to the locking piece.

Preferably, the tip is an angled polyhedron at the edge, and a recess having the same size and shape as the tip may be formed in the middle portion of the third locking projection.

Also, preferably, at the rear end of the third locking protrusion, a locking hole or a locking protrusion may be formed at the position where the USB of the USB unit is exposed to the outside.

According to the above structure, since the USB unit is inserted into the card-shaped base in a sliding manner, the USB unit is easy to handle and easy to carry.

In addition, since the USB unit does not slide arbitrarily without user operation, there is an advantage in that the operation is convenient during use.

In addition, if necessary, the USB unit can be replaced without being removed from the base, and it can be detached from the base and used as a stick.

Base (100)

Base 100 is made of a card-shaped single body 110, the surface is provided with a mounting portion 130 for mounting the USB unit 200, the jaw 111 protrudes along the edge of the back surface.

Therefore, an article suitable for the user's taste, such as a photograph or a business card, having a thickness equal to the height of the jaw 111 may be attached to the back portion surrounded by the jaw 111.

The mounting portion 130 is defined as an area in which the edge of the body 110 is opened and the rest is surrounded by the support wall 120.

Guide grooves 122 are formed along the inner surface of the support wall 120, and the guide grooves 122 of the USB unit 200 to be described later are fitted into the guide grooves 122 and slide therein.

A plurality of locking protrusions 113, 114, 115, and 117 are formed on the inner bottom surface surrounded by the support wall 120, and the locking protrusions 113, 114, 115, and 117 have different characteristics.

The locking protrusion 113 is formed to correspond to the position where the USB unit 200 is completely inserted into the mounting unit 130 to suppress the movement of the USB unit 200, and the locking protrusions 114 and 115 are inserted into the USB port. The USB unit 200 of the USB unit 200 may be formed to correspond to a position where the USB unit 200 is exposed to the outside so that the USB unit 200 may be used.

The catching protrusions 113 have a cross-sectional structure in which the inclinations of the side surfaces of the USB unit 200 are pulled out in pairs are small and the inclinations of the opposite sides are large.

The locking protrusions 114 and 115 serve to fix the T-shaped locking piece 228 to cooperate with each other to use the USB unit 200. Specifically, when the locking piece 228 having the same size and shape is seated in the area formed by the locking protrusion 114 and the locking protrusion 115 spaced apart from the locking protrusion 114, the locking protrusion 114 is the locking protrusion 113. It is formed in pairs and spaced apart as described above to prevent the catching piece 228 from going backward and the catching protrusion 115 prevents the catching piece 228 from moving forward.

In particular, a recess 115a formed in the middle portion of the locking protrusion 115 is formed in a size and shape corresponding to the tip 226 of the locking piece 228 as described below so that the tip 226 does not fall over. It plays a role.

Here, the locking protrusion 114 has a cross-sectional structure opposite to the locking protrusion 113, and the locking protrusion 115 has a cross-sectional structure similar to the locking protrusion 113.

In addition, the locking protrusion 117 is formed to be adjacent to the opening edge of the mounting portion 130 to serve to finally catch the USB unit 200 just before the USB unit 200 is drawn out.

On the other hand, the engaging projection 115 and the engaging projection 117 is formed between the engaging projection 117, the engaging piece 228 of the USB unit 200 passing through the engaging projection 115 is caught, but slightly moved back and forth Can be This locking hole 116 plays a role of forming a boundary in which all of the USB 230 of the USB unit 200 are exposed to the outside, as will be described later. Instead of the locking hole 116, another locking projection may be provided.

USB  Unit 200

The USB unit 200 of FIG. 1 is shown in an inverted state for convenience of description, and when fitted to the mounting portion 130 of the actual base 100, is inserted in an inverted state.

The USB unit 200 is configured to accommodate the USB 230 and the locking member 220 in the single body 210. That is, two compartments are provided in the body 210, and the USB 230 is accommodated and fixed in one accommodating area, and the connection terminal 232 is accommodated so as to be exposed to the outside. In addition, the locking member 220 is received and fixed in the other accommodation area.

The USB 230 and the locking member 220 may be stored and fixed using, for example, a double-sided adhesive tape.

As described above, the guides 212 are protruded on both outer sides of the body 210 to fit in the guide grooves 122 formed in the support wall 120 of the base 100.

The locking member 220 includes a support part 221 and an elastic part 222 positioned inside the support part 221 and elastically bent with respect to the support part 221. That is, three side edges of the elastic part 222 are cut out from the support part 221, and only one side edge is integrally connected.

At the end of the elastic portion 222, the engaging piece 228 is formed to protrude to the outside, the engaging piece 228 is a bar (224) and the bar 224 having a T-shaped round cross section It consists of a tip (226) formed perpendicular to the. In FIG. 1, tip 226 has an approximately hexahedral shape.

Hereinafter, the operation of the USB apparatus having the above configuration will be described with reference to FIGS. 2A and 2B.

In order to couple the USB unit 200 to the base 100, the side where the locking member 220 of the USB unit 200 is located is pushed into the mounting portion 130 of the base 100.

At this time, although the locking piece 228 of the locking member 220 of the USB unit 200 is caught by the locking protrusion 117 of the base 100, the locking piece 228 is caught by the pressing force. Riding over is fitted.

Thereafter, the guide 212 of the USB unit 200 is fitted into the guide groove 122 formed in the support wall 120 of the base 100 and slides smoothly.

The locking protrusions 115 and 113 of the base 100 have a cross-sectional structure having a small inclination of the side in the direction in which the USB unit 200 is drawn out and a large inclination of the opposite side, so that the USB unit 200 can be easily inserted when the USB unit 200 is coupled. Can be.

In this way, as shown in FIG. 2A, the USB unit 200 is completely fitted into the mounting portion 130 of the base 100.

In this state, when the USB unit 200 is pushed and pushed in order to pull out the USB unit 200, the locking piece 228 of the locking member 220 is caught by the locking protrusion 113 of the base 100, but pushing As the elastic portion 222 is elastically deformed by the force, the bar 224 of the locking piece 228 moves over the locking protrusion 113 while moving upward. In this case, the tip 226 of the locking piece 228 passes through the locking protrusion 113 because it is spaced apart from each other.

In the same way, if the locking piece 228 of the USB unit 200 passes over the locking protrusion 114, the locking piece 228 is accommodated in the area formed by the locking protrusions 114 and 115, and thus, the USB The unit 200 is suppressed forward and backward. In particular, the tip 226 formed at the corners in the shape of a hexahedron is precisely matched to the recess 115a to more effectively suppress the movement of the USB unit 200.

In this state, when the USB unit 200 is inserted into a USB port of an electronic device such as a computer, data and power are transmitted and received through the connection terminal 232 formed on the USB 230 of the USB unit 200.

Here, when the force required to insert the USB unit 200 into the USB port is greater than the force that suppresses the reverse of the locking piece 228, the USB unit 200 may reverse, in this case, the USB unit 200 is strongly This can be prevented by gripping.

Optionally, the depth of the recess 115a, i.e., the height of the tip 226, can be increased to further suppress the advancement of the USB unit 200, but the case where the USB unit 200 is withdrawn as necessary is expected. It is necessary to design properly.

On the other hand, when the USB 130 is replaced from the USB unit 200 as needed, if the USB unit 200 is pushed more strongly in the above state, the locking piece 228 rides over the locking protrusion 115 and the locking hole ( 116 is inserted, and the tip 226 of the locking piece 228 is caught by the edge of the locking hole 116 to stop the movement of the USB unit 200. In this state, since all of the USB 230 of the USB unit 200 is exposed to the outside, the user can remove the USB 230 from the USB unit 200 and then replace it with a new USB 230.

Further, if the USB unit 200 is pushed further, it is drawn out from the base 100 and separated. In this state, the USB unit 200 is used as in the conventional stick type.

According to the present invention, since the USB unit is inserted into the card-shaped base in a sliding manner, the USB unit is easy to handle and portable. In addition, since the USB unit does not slide arbitrarily without user operation, operation during use is convenient. In addition, if necessary, the USB unit can be replaced without being removed from the base, and it can be detached from the base and used as a stick.
