Alternatively, the permanent magnet 3 may be installed to keep the connector 2 stored in the receiving groove 11 of the external device main body 1 by the magnetic force of the permanent magnet 3 or the terminal of the connector 2. 24 is characterized in that it is configured to maintain a state of being electrically connected to the elastic terminal 12 of the external device (100).

In addition, the plurality of terminals 24 installed in the connector 2 are installed so as to be exposed to one end and the top or one end and the bottom at the same time in the state electrically connected to the inside of the body (21).

In addition, a cover 25 having a finger insertion groove 26 is integrally formed on a part of the upper surface of the housing groove 11 of the external device main body 1 so that the connector 2 is accommodated in the housing groove 11. When the connector 22 of the connector 2 is covered by the cover 25, it is characterized in that it is not exposed to the outside.

In addition, between the accommodating groove 11 of the external device main body 1 and the coupling portion of the connector body 21 is characterized in that the further prevention and separation prevention means (5) is further provided.

At this time, the misalignment prevention and separation prevention means (5), one and a pair of guide grooves 51 are formed in the vertical and horizontal directions on the front and rear surfaces of the accommodating groove 11 of the external device main body 1, respectively. The front and rear surfaces of the connector body 21 are characterized by protruding one and a pair of guide protrusions 52 opposed to the guide grooves 51 in the horizontal direction, respectively.

Referring to the effect of the connector detachable device of the present invention portable external device configured as described above are as follows.

First, the apparatus of the present invention is a USB device or a similar method to the external device main body 1 and the connector (2) of various external devices 100 of the USB method to be used in mechanical connection with the main device such as a PC, notebook or laptop computer, etc. The permanent magnet 3 and the iron plate 4 are embedded in the main body 1 of the external device 100 and the inside of the body 21 of the connector 2 so as to be opposite to each other. The magnetic force of the permanent magnet 3 is kept on the receiving groove 11 of the external device main body 1, or the terminals 24 of the connector 2 are the elastic terminal of the external device 100 ( The main technical component is to keep the electrical connection to 12).

In this case, an accommodating groove 11 for accommodating the connector 2 is formed on one side of the upper surface of the external device main body 1, and may be molded into a rectangular groove regardless of the shape of the connector 2. In this case, the connector 2 itself may flow in the accommodating groove 11, and the connecting portion 22 of the connector 2 thinner than the thickness of the body 21 may be further inserted into the bottom surface of the accommodating groove 11. The connector 2 may be accommodated in the receiving groove 11 of the external device main body 1 in an inclined form.

Therefore, in the present invention, the bottom surface of the accommodating groove 11 is stepped in a stepped manner so as to face the outer shape of the connector 2 (that is, the bottom surface on which the connection part 22 of the connector 2 is to be raised is the body 21). Carrying or storing the external device 100 by forming a step so as to be higher than the height of the floor to be raised) when the connector 2 is accommodated in the receiving groove 11 as shown in FIGS. 1 to 9. Inside the main body 1 of the external device 100 in a state where the connection part 22 and the bottom of the body 21 are stored in close contact with the bottom surface of the receiving groove 11 having a high and low shape, respectively. In the body 21 of the connector 2, the permanent magnet 3 and the iron plate 4 installed opposite to each other are generated in the permanent magnet 3 from the permanent magnet 3 to attract the iron plate 4 by the magnetic force of the connector 2 ) Itself does not flow or incline inside the receiving groove 11 to maintain a fixed state integrally.

In addition, in the present invention, by adopting a coupling method using the magnetic force of the permanent magnet (3) without adopting a hinge coupling method for the external device main body (1) and the connector (2) by interconnecting the wires for power and signals between the two The accommodating groove 11 is provided with a plurality of elastic terminals 12 in response to the power and signal lines (for example, D +, D-, GND, VBUS, etc.) required by the USB to the receiving groove 11, Inside the external device main body 1 in which the 12 are installed, a permanent magnet 3 or an iron plate 4 for fixing the connector 2 in the receiving groove 11 or maintaining the state in which the connectors are coupled to the terminals is provided. Install on the other side.

At this time, the elastic terminal 12 has a plate spring shape having its own elasticity, and when the elastic terminal 12 having its own elasticity is installed as described above, the magnetic force of the permanent magnet 3 is When the connector 2 itself is coupled to the receiving groove 11 of the external device main body 1, the elastic terminals 12 extend to the terminals 24 of the connector 2 in FIGS. 4 and 5. It stays in elastic contact with the tile.

In the meantime, the connector 2 is manufactured separately from the external device main body 1 in a form having a body 21, a connection portion 22, and a printed circuit board 23, and the body of the connector 2. Also, the terminal 21 may be provided with several terminals 24 for electrically contacting the elastic terminals 12 of the external device 100 described above without a flexible wire.

In this case, the connector 2 is coupled to form an angle of 90 degrees with respect to the external device body 1, or horizontally, that is, to be able to be used in combination with a horizontal, that is, 180 degrees, as shown in FIGS. One terminal may be provided with one terminal 24 in electrical contact with the elastic terminals 12 of the external device 100, and one of the top or bottom surface as shown in Figs. In some embodiments, several terminals 24 may be installed in electrical contact with the elastic terminals 12 of the external device 100.

However, when the terminals 24 installed in the connector 2 are installed only on one side or one of the upper and lower surfaces of the body 21 as in the above two cases, the connector 2 itself may be installed. When coupled to the elastic terminals 12 of (1) it is limited to 90 degrees or at a right angle to the external device main body 1, or 180 degrees horizontally coupled to form a different angle using the same connector (2) If the installation position of the connector for coupling the external device 100 installed in the main device is different because it cannot be coupled to the external device 100 by changing it, there is a problem in that it cannot be used in combination.

Therefore, according to the present invention, one end surface and one end surface or one end surface as shown in FIGS. 9 and 10 in a state in which several terminals 24 installed in the connector 2 are electrically interconnected inside the body 21 as necessary. The same connector 2 is perpendicular to the external device 100 at a right angle to the external device 100 as shown in the solid line of FIG. 10 in response to the installation position of the external device 100 coupling connector installed in the main device by being installed to be exposed to both the lower surface and the lower surface simultaneously. It may be used in combination with a fork, or may be used by being horizontally combined with 180 degrees as shown in the virtual line of FIG. 10, and several terminals 24 may be simultaneously exposed to one side and the top or one side and the bottom as shown in FIG. The connector 2 may be accommodated in a storage groove 11 formed in the main body 1 of the external device 100 to be carried and stored.

Meanwhile, as described above, the iron plate 4 or the permanent magnet 3 is installed inside the body 21 of the connector 2 having the several terminals 24 installed therein as opposed to the external device 100. The connector 2 is carried and stored in a state where the connector 2 is stored on the receiving groove 11 of the external device main body 1 by using the magnetic force of the permanent magnet 3, or the terminals 24 of the connector 2 It may be used in combination with the main device in a state in which it is electrically connected to the elastic terminal 12 of the external device 100.

At this time, the permanent magnet (3) is installed in any one of the inside of the bottom of the receiving groove 11 of the external device main body 1, or the inside of the connector body 21, as described above, the iron plate (4) On the contrary, it is possible to install and use the inside of the connector body 1 in which the permanent magnet 3 is not installed, or the inside of the external device main body 1. The magnetic force generated in the permanent magnet 3 is omitted, although not shown. Since it may affect a storage device installed in the main body 1 of the external device 100, a wireless communication device, a data communication device, or the like, the strength of the magnetic force may be selected so as to be small so as not to affect them.

In addition, it is more preferable to install the connector body 21 therein rather than the inside of the external device main body 1 in which a storage device, a wireless communication device, or a data communication device is incorporated.

In addition, when the upper surface of the receiving groove 11 of the external device main body 1 is formed to be completely open as described above, when the connector 2 is stored in the receiving groove 11, Since the upper surface portion of the connection portion 22 has an exposed shape as shown in FIGS. 1, 9, and 11, the external shape of the external device itself is not beautiful, and the permanent magnet 3 is externally carried during storage and storage of the external device. When an impact or external pressure greater than the magnetic force of the connector 2 itself is easily detached from the receiving groove 11 of the external device main body 1.

Therefore, in the present invention, the lid 25 is integrally extended to a part of the upper surface of the accommodating groove 11 of the external device main body 1 as shown in FIG. 8 (a) (b) to the accommodating groove 11. When the connector 2 is accommodated, as shown in FIG. 8A, the connection part 22 of the connector 2 is covered by the cover 25 and is not exposed to the outside, thereby completely solving the above problem.

In this case, when the ends of the cover 25 are formed in a straight line, they are brought into close contact with the upper surface of the body 21 of the connector 2 housed in the receiving groove 11 so that no gap is generated between them. There is a possibility that it is difficult to separate the connector 2 from the groove 11.

Therefore, in the present invention, when the cover 25 is integrally extended to a part of the upper surface of the accommodating groove 11 of the external device main body 1, a finger part of the user may be inserted into the free end of the cover 25. By further forming the insertion groove 26, it is possible to easily separate the connector (2) accommodated in the receiving groove 11 of the external device main body (1).

Meanwhile, in the present invention, the external device main body 1 and the connector 2 are basically manufactured separately, and the connector 2 is normally used by using a permanent magnet 3 having a magnetic force for attracting the iron plate 4. It can be stored and carried in a state where it is stored and fixed in the storage groove 11 of the external device main body 1, and when it is connected to the main device, the connector 2 is separated from the storage groove 11 and then permanently stored therein. The connector 2 is an external device 100 in which the elastic terminal 12 of the external device main body 1 and the terminals 24 of the connector body 21 are electrically connected precisely using the magnetic force of the magnet 3. ) To 90 degrees or 180 degrees with respect to each other, in which the external device 100 and the external device to which the present invention is applied by providing a basis for not having any separation preventing means between the coupling portion of the connector (2) Claim device 100 Of the external device body 1 itself is automatically separated from the connector body 1 when a shock or the like that is greater than the magnetic force of the permanent magnet 3 from the outside is directly applied to the external device body 1 from the outside. The possibility of damage to the components of the coupling part, including, can be completely excluded.

However, some of the external device 100 to which the present invention is applied may have a relatively large weight, and in the case of such a heavy weight, the connector 2 and the external device should be used only when the permanent magnet 3 having a large magnetic force is used. The main body 1 may maintain a state of being coupled to each other regardless of the weight of the external device.

 However, in the case of a storage device or a wireless communication and data communication device installed in some external device 100, a sensitive reaction occurs to the magnetic force of the permanent magnet 3, even if the weight of the external device 100 itself is relatively high. When the permanent magnet 3 having a large magnetic force cannot be installed, it may occur, in which case a separate separation prevention means is required.

In addition, in the case of the external device adopting the USB method, although the installation order of the power supply and the signal line is determined in the order of D +, D-, GND, VBUS, etc., the storage groove 11 of the external device main body 1 ) And a couple of elastic terminals 12 and connectors installed in the external device main body 1 due to user's carelessness, when there is no misalignment prevention means between the coupling part of the connector body 21 and the connector body 21. Several terminals 24 installed in the body 21 are not in contact in a predetermined order, so when the external device is connected to the main device, the external device may not perform the desired operation.

Therefore, in the present invention, in order to solve the above two requirements at the same time, the misalignment prevention and separation prevention means (5) between the accommodating groove 11 of the external device main body 1 and the coupling portion of the connector body 21 is further added. Installed.

At this time, the misalignment prevention and separation prevention means (5) can be presented a variety of structures, in the present invention, as shown in Figure 11 and 12 in the front, rear of the receiving groove 11 of the external device main body (1) One and a pair of guide grooves 51 are formed in the vertical and horizontal directions, respectively, and the front and rear surfaces of the connector body 21 may be coupled to the guide grooves 51 in the horizontal direction by sliding in a sliding manner. One and a pair of guide protrusions 52 were each formed to protrude.

In the above, the shape of the guide groove 51 and the guide protrusion 52 as the misalignment prevention and separation prevention means 5 is adopted so that the external device main body 1 and the connector 2 are separated from each other, even in the event of external shock. The guide grooves 51 and the guide protrusions 52 are formed on one of the front or the rear (front in the drawing) and a pair of the other rear or front (the rear in the drawing) Due to the misalignment of the connector 2, several elastic terminals 12 installed in the external device body 1 and several terminals 24 installed in the connector body 21 do not contact each other in a predetermined order. This is to prevent it from doing so.

In addition, unlike one and a pair of guide protrusions 52 protruding only in the horizontal direction from the front and rear of the connector body 21 of the misalignment prevention and separation prevention means (5), the external device main body ( The reason why the one and the pair of guide grooves 51 formed on the front and rear surfaces of the accommodation groove 11 of 1) in the vertical and horizontal directions, respectively, is that the connector 2 itself is the storage groove of the external device main body 1. The direction of the guide protrusion 52 when the connector 2 is coupled to form an angle of 180 degrees with respect to the external device main body 1 to connect the external device 100 to the main device, including when it is stored in the (11), This is because the guide projection directions are 90 degrees different from each other when coupling the connector 2 to form the 90 ° with respect to the external device main body 1 in order to connect the external device 100 to the main device.

In this way, when the misalignment prevention and separation prevention means 5 are further installed between the accommodating groove 11 of the external device main body 1 and the coupling portion of the connector body 21, the connector 2 itself is connected to the external device. When the housing groove 11 of the main body 1 is accommodated, one and a pair of guide protrusions 52 protruding from the front and rear surfaces of the connector body 21 accommodate the external device main body 1 as shown in FIG. The connector 2 itself is combined with the magnetic force of the permanent magnet 3 so that the connector 2 itself is fitted in the form of being fitted into the one and a pair of guide grooves 51 formed in the horizontal direction from the front and rear of the groove 11. By the locking action of the guide protrusion 52 fitted in the 51) to maintain a more perfect fixed state of course, the connector (2) itself can be separated only through one side opening of the receiving groove 11, not separated into the upper surface portion in the drawing. Will be.

In addition, in order to connect the external device 100 to the main device to the connector 2 to form a 90 degree with respect to the external device main body 1 as shown in the solid line of Figure 12 to the front, rear of the connector body 21 Protruding one and a pair of guide protrusions 52 are fitted into one and a pair of guide grooves 51 formed in the vertical direction from the front and rear surfaces of the receiving groove 11 of the external device main body 1, respectively. When the connector 2 is coupled to the external device main body 1 to form 180 degrees as shown by the virtual line of FIG. 12, one and a pair of guide protrusions protruding from the front and rear of the connector body 21 ( 52 may be fitted into one and a pair of guide grooves 51 formed in the horizontal direction on the front and rear surfaces of the receiving groove 11 of the external device main body 1, respectively.

As such, when the connector 2 itself is coupled to form the 90 ° or 180 ° with respect to the external device main body 1, one and a pair of guide protrusions 52 protruding from the front and rear of the connector body 21 are respectively. When combined in the form of being fitted in one or a pair of guide grooves 51 formed in the horizontal or vertical direction on the front and rear of the receiving groove 11 of the external device main body 1, the weight of the external device itself is Even if the magnetic force of the permanent magnet goes out or the external impact is greater than the magnetic force of the permanent magnet, the guide protrusions 52 of the connector body 21 fitted into the guide groove 51 of the external device main body 1 are caught. It is not separated from each other by action.
