Description

BNC terminal locking device {A LOCKING APPARATUS FOR BNC TERMINAL}

The present invention relates to a BNC terminal locking device for locking a so-called BNC terminal used for data transmission in an electric device.

Recently, there have been incidents of outsiders breaking into financial institutions or government-affiliated institutions or non-administrators entering and withdrawing data stored on computers, causing a great social impact. .

In consideration of this point, recently, various technologies have been proposed to prevent the connection of unauthorized data transmission cables or connectors by physically blocking the computer's USB port, network equipment, and electronic products.

In addition, various methods and apparatuses have been proposed to physically block a LAN port to which a LAN cable is connected, that is, a network port to block data retrieval through the network port.

To this end, the present applicant has developed a device for locking a USB port, a device for locking a LAN port, a device for locking a network port lock, and the like.

Meanwhile, a so-called BNC terminal is used for cable connection in a TV or radio among various data transmission methods as described above.

As shown in FIG. 1, the BNC terminal is a method of fastening the cable-side terminal by rotating the cable-side terminal by 45 degrees after connecting the cable-side terminal to the electronic device-side terminal. These BNC terminals are similar to RCA terminals, but the central core is as thin as a needle.

Since such a BNC terminal has a structure advantageous for digital signal transmission, it is mainly used in electronic devices accompanied by sound output.

However, since virus penetration and data leakage from the outside are possible even through such a BNC terminal, there is a need for a lock device to increase security by blocking use by anyone other than an authorized person.

The locking module body 211 is horizontally connected between a pair of sidewalls 211a that are inserted into close contact with both sidewalls of the main opening 121 of the second coupling part 120, and a pair of sidewalls 211a. At the upper end of the horizontal wall 211b and the side wall 211a, an upper wall 211c is extended to face the horizontal wall 211b and spaced apart from each other. The pattern module 220 is slidably coupled between the horizontal wall 211b and the upper wall 211c. The horizontal wall 211b is formed with a sub-locking part 217 integrally connected to it. The free end of the sub-locking part 217 is closer to the upper wall 211c than the horizontal wall 211b toward the upper wall 211c. It is formed to be inclined, interfering with the locking jaws 223b of the pattern module 220 to block the locking module 210 and the locking-coupled pattern module 220 from being relatively movable.

The main locking part 213 is connected to the rear end of the upper wall 211c. Preferably, a pair of the main locking parts 213 are installed symmetrically connected to each other at the rear end of each upper wall 211c. The main locking part 213 is connected from the rear end of the upper wall 211c to a vertical extension part 213a extending upward, and the vertical extension part 213a faces the horizontal wall 211b and extends to be spaced apart. It has an elastic locking portion (213b). A locking protrusion 216 is formed to protrude from the upper portion of the end of the elastic locking portion 213b, and is fitted and coupled to the locking hole 105 formed in the device body 100 .

The interfered part 215 is installed to connect the ends of the pair of elastic locking parts 213b to each other. The interfered part 215 is formed to have the same height as the lower surface of the elastic locking part 213b, and the upper surface is formed to have a lower height than the upper surface of the elastic locking part 213 . And the corner portion between the upper surface and the rear surface of the interfered portion 215 is formed to be rounded so that the interference portion 225 of the pattern module 220 to be described later can be in contact naturally. When the elastic locking part 213 moves in a direction in which the pattern module 220 is spaced apart to protrude forward of the locking module 210 (locking release direction), the interfered part 215 is caused by the interference part 225 . It is elastically deformed by being pressed by interference, and the locking protrusion 216 in the locking hole 105 of the device body 100 may be released from the locking state during the elastic deformation.

The pattern module 220 includes a front wall 221 having a shape corresponding to the front surface of the second coupling part 120 , a horizontal coupling part 223 extending horizontally from the front wall 221 , and a horizontal coupling part The lower surface of the main locking part 213 of the locking module 210 protrudes from the end of the 223 to the upper surface of the interference part 225 extending upward, the rear of the front wall 221 and the horizontal coupling part 223 . has an interference wall 227 to contact and interfere.

The front wall 221 has a front shape corresponding to the shape of the first coupling part 120 of the device body 100 . A key hole 221a into which the key 320 of the extraction tool 300 is inserted is formed through the front wall 221 . The key hole 221a is connected to the pattern groove 223a formed in the lower surface of the horizontal coupling part 223 . On the inner wall of the pattern groove 223a, an intaglio and embossed pattern is formed to correspond to the key pattern of the key 320 . In addition, a stepped locking jaw 223b is formed at the end of the pattern groove 223a by contacting the end of the sub-locking part 217 of the locking module 210 .

The horizontal coupling part 223 extends to the rear of the front wall 221 and is connected, and is coupled to be reciprocally movable between the horizontal wall 211b and the upper wall 211c of the locking module body 211 .

The interference part 225 is formed to extend roundly upward from the rear end of the horizontal coupling part 223 . The interference part 225 is disposed at a height corresponding to the interference target part 215 of the locking module 210 . Therefore, when the pattern module 220 is completely inserted into the locking module 210 and unlocked by pulling the pattern module 220 using the pull-out mechanism 300 in the coupled locked state, as shown in FIG. The part 225 contacts and presses the interfered part 215 . Then, the elastic locking portion 213b is elastically deformed to separate the locking protrusion 216 from the locking hole 105 of the device body 100 .

Meanwhile, the locking jaw 223b corresponds to the rear wall of the pattern groove 223a formed under the horizontal coupling part 223 and is formed at a position where the end of the sub locking part 217 can be in contact. Accordingly, as shown in FIG. 18 , in a state in which the pattern module 220 is completely pushed to the locking module 210 and locked, the locking jaw 223b is caught at the end of the sub locking part 217 , so the pattern module 220 cannot be moved to protrude forward of the locking module 210 (to protrude from the second coupling part). On the other hand, as shown in FIG. 20 , when the key 320 of the extraction tool 300 is inserted into the key hole 221a, the key 320 enters the pattern groove 223a and is located in the pattern groove 223a. The sub-locking part 217 is interfered and pushed out. Then, the locking jaw 223b is separated from the sub-locking part 217 to move the pattern module 220 to protrude forward of the locking module 210 as shown in FIG. 21 .

The interference wall 227 protrudes toward the upper portion of the horizontal coupling portion 223 and the rear of the front wall 221 , and is formed at a height at which the lower surface of the elastic locking portion 213b can be in contact. Therefore, before withdrawing the pattern module 220 to be spaced apart from the locking module 210 by a predetermined distance using the pull-out tool 300, the lower surface of the elastic locking part 213b is in contact with the interference wall 227 as shown in FIG. Since the state is maintained, the elastic deformation of the main locking part 213 is blocked.

24 and 25 , the extraction tool 300 includes a main body case 310 , a pair of keys 320 and a pair of keys 320 installed to protrude from the front end of the main body case 310 . It has a manipulation unit 330 that operates to approach and spaced apart from each other. A so-called key pattern is formed on the outer edge of the key 320 in which engraving and embossing are formed in a predetermined pattern. The key 320 is inserted into the key hole 221a of the pattern module 220, and in the inserted state, the operation unit 330 is operated to spread the pair of keys 320 so that the key pattern of the key 320 is formed in the pattern groove ( 223a). The extraction tool 300 having the above configuration may have various configurations, and the key pattern of the key 320 and the pattern shape of the pattern groove 223a may be designed and formed in various ways.

25 shows a state in which a pair of keys 320 are approached to each other, and in this state, they enter the keyhole 221a. 14 shows a state in which the keys 320 are opened from each other, and is opened by manipulating the manipulation unit 330 while being inserted into the key hole 221a. The gapped keys 320 are engaged and coupled to the pattern inside the pattern groove 223a.

Hereinafter, the operation and effect of the BNC lock device 10 according to the embodiment of the present invention having the above configuration will be described in detail.

First, as shown in FIGS. 16A and 16B , the first coupling part 110 of the device body 100 is inserted and coupled to the BNC terminal 20 installed on the body of the electronic device. To this end, first, the guide groove 113 of the device body 100 is positioned to face the locking protrusion 25 of the BNC terminal 20 . In order to easily position the guide groove 113 at the position of the locking protrusion 25, the display cutout 103 is formed on the outer surface of the device body 100 to correspond to the position where the guide groove 113 is formed. it's good

When the device body 100 is further pushed toward the BNC terminal 20 in the state of FIG. 16b , the locking protrusion 25 is moved to the end of the guide groove 113 .

When the device body 100 is rotated in this state, as shown in FIG. 16d , when the BNC terminal 25 is rotated to the left, the locking protrusion 25 and the locking slit 115 are relatively guided, and the relative While moving, the locking protrusion 25 is positioned on the protrusion seating portion 115b of the locking slit 115 . As such, in order for the locking protrusion 25 to be positioned on the protrusion seating part 115b, the device body 100 so that the locking protrusion 25 of the BNC terminal 20 moves to the end of the guide groove 113 of the first coupling part 110 . ), and then rotates away from the BNC terminal 20 to perform a backward movement operation.

In this state, as shown in FIG. 17 to block the relative rotation of the device body 100 with respect to the BNC terminal 20, that is, the movement in the X-axis direction, the locking unit 200 is attached to the second coupling part 120. insert At this time, the locking module 210 and the pattern module 220 are inserted into the second coupling part 120 in a state in close contact with each other as shown in FIGS. 15 and 16 .

When the locking unit 200 is inserted into the second coupling part 120 of the device body 100 , as shown in FIGS. 18 and 19 , the locking protrusion 216 formed on the main locking part 213 is formed on the device body. (100) is inserted into the locking hole (105) is coupled. In this state, the lower surface of the main locking part 213 comes in contact with the interference wall 227 of the pattern module 220 and is supported so as not to be elastically deformed downward.

In addition, as shown in FIG. 18 , the locking jaw 223b of the pattern module 220 is caught by the sub-locking unit 217 of the locking module 210 to maintain the locked state, so that the pattern module 220 is the locking module 210 . It is blocked from moving protruding to the front of the Accordingly, the pattern module 200 cannot move freely with respect to the locking module 210, and the interfering part 225 of the pattern module 200 moves in a direction in which the interfering part 215 of the locking module 210 interferes. will block you from doing Therefore, in this state, the locking unit 200 is completely coupled to the second coupling part 120 of the device body 100 to maintain the locked state, so that the device body 110 can be separated from the BNC terminal 20 . You can keep it locked. Accordingly, it is possible to prevent data leakage through the BNC terminal 20 and prevent a child or an intruder from damaging the BNC terminal 20 by inserting a stick or an awl.

On the other hand, in the state in which the lock device 10 of the present invention is coupled to the BNC terminal 20 and blocked as described above, in order to separate the lock device 10 coupled to the BNC terminal 20, a pull-out tool 300 is used. should be used More specifically, the keys 320 of the extraction tool 300 are inserted into the keyhole 221a as shown in FIG. 20 in a state in which they approach each other as shown in FIG. 25 . Then, the key 320 that has entered the pattern groove 223a through the key hole 221a interferes with the sub-locking part 217 of the locking module 210 positioned inside the pattern groove 223a to form the pattern groove. Extrude from (223a). Accordingly, the locking jaw 223a is separated from the sub-locking part 217 to release the locked state.

In addition, the pair of keys 320 inserted into the key hole 221a operate the manipulation unit 330 to spread them apart. Then, as shown in FIG. 24 , the key pattern of the key 320 is engaged with the pattern of the pattern groove 223a inside the key hole 221a to be coupled to the widened keys 320 . In this state, as shown in FIG. 11 , the pattern module 220 is spaced apart to protrude toward the front of the locking module 210 by pulling the withdrawal tool 300 . Then, the interference wall 227 of the pattern module 220 is separated from the lower surface of the main locking part 213, and the pressing part 225 presses the pressing part 215 to press the locking protrusion 216. It is separated from the locking hole 105 and released.

Therefore, when the pull-out tool 300 is further pulled out in the state of FIG. 22 , the locking unit 200 comes out completely from the second coupling part 120 of the device body 100 and is separated.

As such, when the locking unit 200 is separated from the device body 100, the device body 100 is rotated in the opposite direction at the time of coupling so that the locking protrusion 25 moves to the end of the guide groove 113 as shown in FIG. 16c. After doing so, it is possible to separate the device body 100 from the BNC terminal 20 by pulling it.

As such, according to the BNC terminal lock device 10 according to the embodiment of the present invention, when the lock unit 200 is coupled to the device body 100 after coupling the device body 100 to the BNC terminal 20, naturally The locked state can be maintained to protect the BNC terminal 20 by blocking it.

In addition, in the locking unit 200 , the locking state and the unlocking state in the device body 100 are determined according to the coupling state between the locking module 210 and the pattern module 220 . And only by using the withdrawal mechanism 300 having the key 320 coupled to the key hole 221a of the pattern module 220, the pattern module 220 can be primarily separated from the locking module 210 . Therefore, the locking unit 200 can be separated from the device body 100 only by using the permitted withdrawal mechanism 300 , thereby further strengthening the security of the BNC terminal 20 .

In the foregoing, the present invention has been shown and described in connection with preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the construction and operation as shown and described as such. Rather, it will be apparent to those skilled in the art that many changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
