Description

USB port lock with spikes

The present invention relates to a USB port locking device that is inserted into a USB port, such as a computer, and more particularly, to a USB port locking device that is fixed by using spikes to a terminal block provided inside the USB port.

Recently, as computer security problems such as illegal information leakage and virus propagation through USB storage devices have emerged as social problems, interest in the security of computer USB ports is increasing.

USB port security methods include a software method of monitoring the use of each computer's USB port on the server, and a physical security method of closing a corresponding USB port by inserting a port lock device into the USB port of the computer.

There are several types of port locks used for physical security. As an example, the port locking device 30a shown in FIG. 1 (a) is inserted into the USB port 10 of the computer 20 by force-fitting, and after being mounted, is inserted into the key hole 38 formed at the rear end thereof. A type that can be removed by inserting a private key.

As another example, the port lock device 30b shown in FIG. 1 (b) is a hook 35 formed on the USB plug 31 inserted into the USB port 10 of the computer 20, as shown in FIG. As described above, while the hook 35 is caught in the hole 15 provided in the housing 11 of the USB port 10, the port lock device 30b is coupled so as not to be pulled out.

The hook-type port lock device 30b has a type that can not be removed once it is mounted and a type that can be pulled out by lifting the lock by lifting the hook 35. In addition, there is a type having a gender coupling part 32 and a type without a gender coupling part 32 as shown in the figure. Since the gender coupler 32 has a terminal arrangement different from that of the USB standard connector, only a dedicated gender (not shown) may be connected.

However, the conventional port locking device has some problems as follows.

First, the interference fit locking device (30a) is inserted into the USB port 10, there is a limit that is difficult to completely prevent the forced extraction by using a bite tool from the outside. In addition, since the interference locking device 30a is completely inserted into the inside of the USB port 10 so that it cannot be pulled from the outside, forming a gender coupling part capable of connecting gender like the hook-type port locking device 30b at the rear end thereof. It has a hard disadvantage.

Second, there is a problem that the hook-type port locking device 30b cannot be used when there is no hole in which the hook 35 is caught in the housing 11 of the USB port 10.

As shown in Fig. 2, most of the USB port housings 11 have elastic pieces protruding inward, and since holes are formed around the elastic pieces, hooks of the port locking device can be hooked to these holes.

However, the USB standard specifies the location of the receptacle contact of the USB port (also called 'USB receptacle'), the width of the terminals, the spacing of the terminals, the size of the terminal block, the size of the housing, the material, etc. Specifications for the shape or hole size around the elastic piece are not specified.

As a result, the location and size of the holes formed in the housing of the USB port (USB receptacle) are often different from manufacturer to manufacturer, and there are even products without holes. In particular, USB ports used in expensive server computers with high security needs are known to have no holes in the housing.

Thus, if the position and size of the hole formed in the housing of the USB port is different for each product, one hook type port lock device 30b cannot be used universally from the user's point of view, so it is inconvenient to purchase and manage various product lines. From the standpoint of product variety, there is a problem that productivity decreases and production cost increases.

In addition, if there is no hole in the USB port housing, the hook-type port lock device 30b cannot be used at all, so the interference-type port lock device 30a cannot be used, but if the lock-type port lock device 30a is used, As described above, there is a problem in that it is difficult to connect gender and the like at the rear end and take a risk of pulling out using a tool.

For this reason, there is an increasing demand for a port locking device having a new locking method rather than an interference fit or hook type.

First embodiment

3 is a perspective view showing the port locking device 100 according to the first embodiment of the present invention. First, for convenience of description, in the present specification, the side inserted into the USB port of the computer in the port lock device 100 is called the front end and the opposite side is called the rear end, and the direction from the front end to the rear end will be defined in the longitudinal direction. This is the same also in the case of the port locking device 100a according to the second embodiment of the present invention described later.

As shown in FIG. 3, the port locking device 100 according to the first embodiment of the present invention includes a main housing 130, a USB plug 110 protruding toward a tip end from the main housing 130, and a main housing ( The gender coupling part 120 formed at the rear end side of the 130 and the wedge unit 150 having a key hole 155 formed on the upper surface of the gender coupling part 120 is inserted from the rear end of the main housing 130 to the inside of the USB plug 110.

The wedge unit 150 may be fully inserted into the port locking device 100, as shown in Figure 3 (a), by inserting the key unit (400 in Figure 15) into the key hole 155, Figure 3 (b) As shown in), it can also be pulled out to the rear end.

Gender coupling unit 120 is for coupling a dedicated gender (200a, 200b of FIG. 4), as shown in the figure may be a female (male) or vice versa (male). However, if the gender coupling unit 120 is a USB standard connector, anyone can connect the USB device to the port lock device 100, so that the terminal arrangement, the number of terminals, and / or the terminal size of the gender coupling unit 120 are USB standard. It is desirable to be different from the connector.

4 is a diagram illustrating a combination of various types of genders 200a and 200b in the gender coupling part 120 of the port locking device 100, and the gender coupling part 120 is formed at the tip of each gender 200a and 200b. A corresponding first coupling part 210 is formed and a second coupling part 220 is formed at a rear end thereof.

Since the gender coupling part 120 is not a USB standard connector, the first coupling part 210 of the gender 200a and 200b should not be a USB standard connector, but the second coupling part 220 is a USB standard connector. desirable.

Therefore, a person possessing a gender 200a, 200b may have a desired USB device (USB keyboard, USB mouse, USB memory, etc.) even if the port lock device 100 is installed in the USB port 10 of the computer. USB hub, USB reader, USB charging cable, etc.) can be connected to use the corresponding USB port (10). At this time, by installing an electronic circuit in the gender (200a, 200b) it can limit the use range, etc. This will be described in detail in Korean Patent No. 10-1580572 of the present applicant.

Hereinafter, the structure of the port locking device 100 according to an embodiment of the present invention will be described in more detail.

First, Figure 5 and Figure 6 shows the longitudinal cross-section of the port locking device 100, respectively showing the state in which the wedge unit 150 is pulled back and pushed.

As shown in the figure, the main housing 130 has a cylindrical shape penetrating from the front end to the rear end, and the rear end of the plug housing 111 of the USB plug 110 is coupled to the front end, and the cap 131 is coupled to the rear end. . The cap 131 has through holes formed at positions corresponding to the gender coupler 120 and positions at which the wedge unit 150 passes.

In the main housing 130 and the plug housing 111, the internal spaces communicate with each other, and the substrate 112 is installed in the communicated internal spaces.

On the upper surface of the substrate 112, USB terminals (Vbus, D-, D +, GND) and a gender coupling part 120 according to the USB standard are mounted, respectively. Although not shown in the drawing, a circuit pattern is formed on the upper surface of the substrate 112 to electrically connect the respective USB terminals Vbus, D-, D +, and GND with the terminals of the gender coupler 120. In addition, a semiconductor chip and peripheral components for performing a predetermined function may be mounted on the substrate 112.

USB terminals (Vbus, D-, D +, GND) are located inside the plug housing 111, the gender coupling unit 120 is preferably located inside the main housing 130.

In particular, as shown in detail in FIG. 7, a through hole 113 is formed in the substrate 112 between the Vbus terminal and the D- terminal, and between the D + terminal and the GND terminal, and the side edges adjacent to the Vbus terminal and the GND terminal. Edge grooves 114 are formed in the adjacent side edges, respectively.

In the drawing, the through hole 113 is not formed between the D- terminal and the D + terminal, which is according to the USB standard, since the gap between the D- terminal and the D + terminal is much smaller than that between other terminals. This is because it is difficult to form. However, the present invention does not exclude the formation of the through hole 113 between the D- terminal and the D + terminal.

Since the use of the through hole 113 and the edge groove 114 is to pass through the spike 145 of the locking unit 140 located below the substrate 112, the through hole 113 and the edge groove in the present specification. As the term encompassing (114), the name penetration is used interchangeably.

The spike 145 passes through the through part so as to be embedded in the terminal block 12 provided in the USB port 10 of the computer so as to prevent the port locking unit 100 from being pulled out.

The substrate 112 is installed at a height approximately half that of the inner space of the plug housing 111 and the main housing 130.

The space formed on the upper portion of the substrate 112 in the plug housing 111 is a space in which the terminal block (see 12 in FIG. 12) formed in the USB port of the computer is inserted as the terminal block insertion space 1102.

In addition, the lower space of the substrate 112 formed from the main housing 130 to the plug housing 111 is a space into which the wedge unit 150 is inserted as the wedge insertion space 1104.

Since the plug housing 111 is a part inserted into the USB port 12 of the computer 20, the plug housing 111 should have a USB standard, and the USB terminals (Vbus, D-, D +, and GND) and the substrate 112 formed on the substrate 112. Terminal block insertion space (1102) formed on the top of the should also have a USB standard.

The first substrate support member 161 and the second substrate support member 162 are positioned under the substrate 112. The first substrate supporting member 161 may include a bottom support portion for supporting the lower portion of the substrate from a leading end of the substrate 112 to a position corresponding to a rear end of the USB terminals Vbus, D−, D +, and GND, and the amount of the substrate 112. It includes a side support for supporting the side.

The bottom support portion of the first substrate support member 161 is preferably provided with the same or larger through portion at each position corresponding to the through portions 113 and 114 of the substrate 112. Therefore, the spike 145 to be described later passes through the first substrate supporting member 161 and the substrate 112 and is embedded in the upper USB terminal block 12.

The second substrate support member 162 is positioned on the same plane as the bottom support of the first substrate support member 161 and has a USB terminal (Vbus, D-, D +, GND) formed from the rear end of the substrate 112. It can have a length up to the end of.

Accordingly, the bottom of the substrate 112 is supported by the first substrate support member 161 and the second substrate support member 162, and the side surface is supported by the side support of the first substrate support member 161.

The locking unit 140 is coupled to the lower portion of the substrate 112. Specifically, as shown in FIG. 7, in a state where the substrate 112 is positioned above the locking unit 140, the locking is performed using the substrate fixing clip 149 protruding upward from both edges of the locking unit 140. The substrate 112 is bonded to the unit 140.

As shown in FIG. 8, the locking unit 140 includes a fixing part 141 fixed to the substrate 112, and a plurality of spikes 145 extending to the tip of the fixing part 141 and protruding upward. It includes an elastic portion 142. It is preferable that the locking unit 140 is entirely made of metal, and if the synthetic resin material is used, at least the spike 145 is preferably made of metal.

The fixing part 141 is coupled to the substrate 112 and does not move, and preferably has a plate shape parallel to the substrate 112.

The substrate fixing clip 149 protrudes upwards to face each other at both edges of the fixing part 141 facing each other, and the sidewall 148 is formed to protrude from the rear end of the fixing part 141.

The substrate fixing clip 149 presses the side or top surface of the substrate 112 to support the substrate 112 so that the substrate 112 does not fall out, and the sidewall 148 prevents the movement of the substrate 112 in the longitudinal direction.

A groove into which the substrate fixing clip 149 is inserted may be formed at the edge of the substrate 112. In this way, the fixing portion 141 of the locking unit 140 is more firmly fixed to the substrate 112.

The fixing part 141 may include a stopper 147. As shown in FIGS. 5 and 6, the stopper 147 is a part caught by the locking hole 153 or the locking jaw 157 of the wedge unit 150 and prevents the wedge unit 150 from moving to the rear end side. do.

The stopper 147 is a plate having an approximately rectangular shape and extends from the rear end edge of the through hole 146 formed in the fixing part 141 to the front end side. In addition, the stopper 147 is not parallel to the fixing part 141, and has a downward inclination in which height decreases toward the tip. Therefore, when the stopper 147 is pushed up, the stopper 147 receives an elastic force downward.

The elastic part 142 has a downward slope in which the rear end thereof is lowered toward the front end in a state where the rear end is connected to the fixing part 141, and thus, when the elastic part 142 is pushed up while the fixing part 141 is fixed, the elastic part 142 is subjected to an elastic force downward.

Meanwhile, the elastic part 142 includes a plurality of spikes 145 protruding upwards at positions corresponding to the through holes 113 and the edge grooves 114 formed in the substrate.

The spike 145 must be absolutely prevented from interfering with the USB terminals (Vbus, D-, D +, and GND) formed on the substrate 112. For this purpose, each spike 145 has a through hole 113 of the substrate 112. And it should be formed to pass through the center of the edge groove 114 in the width direction. In addition, each spike 145 preferably has a thickness that is much thinner than the width of the through hole 113 and the edge groove 114 of the substrate 112.

In addition, the spike 145 should be able to be embedded in the terminal block 12 of the USB port to a sufficient depth, and must exhibit a high bearing capacity for the longitudinal direction of the port lock device (100). This is because if the spike 145 is deformed when the port locking unit 100 is forcibly pulled out, the port locking unit 100 may be pulled out.

To this end, in the embodiment of the present invention, each spike 145 is formed in a triangle having a base in the longitudinal direction of the port locking device 100, while the position corresponding to each through hole 113 and the edge groove 114 Two spikes 145 each are formed by being spaced apart in the longitudinal direction.

However, since the shape or number of spikes 145 is not necessarily limited to those shown in the drawings, the shape or number may be adjusted as necessary.

In addition, although the elastic part 142 includes two branches 143 formed to be parallel to each other in the longitudinal direction, it is shown that the spikes 145 are formed at both side ends of each branch 143, but are not limited thereto. The spike 145 may directly protrude upward through plate punching without forming the branch 143.

The substrate 112 may be directly coupled to the fixing part 141 of the locking unit 140, but in the embodiment of the present invention, as shown in FIG. The second substrate support member 162 is positioned on the upper part of the fixing part 141, and then the substrate 112 is positioned on the second substrate support member 162 as shown in FIG. 7.

To this end, the side wall 148 formed on the fixing part 141 preferably has a height equal to or greater than the sum of the thicknesses of the substrate 112 and the second substrate supporting member 162, and the substrate fixing clip 149 It is also desirable to have a height corresponding thereto.

The second substrate support member 162 may be installed so as not to cover the spike 145, and the front end surface of the second substrate support member 162 may contact the rear end surface of the first substrate support member 161. As described above, the spike 145 passes through the through portions formed in the first substrate support member 161 and the through portions 113 and 114 of the substrate 112.

10, the second substrate support member 162 and the substrate 112 are sequentially positioned on the locking unit 140, and the second substrate support member 162 and the substrate 112 are connected to the substrate fixing clip 149. In the fixed state, the main housing 130 is coupled after supporting the tip and side surfaces of the substrate 112 using the first substrate support member 161.

Accordingly, the fixing part 141 of the substrate 112 and the locking unit 140 is firmly fixed to the main housing 130. The substrate 112 is supported by the first and second substrate support members 161 and 162 while its front and side surfaces are supported by the first substrate support member 161.

When the plug housing 111 is coupled to the front end of the main housing 130, as illustrated in FIGS. 5 and 6, the terminal block insertion space 1102 and the wedge insertion space 1104 are disposed on the upper and lower portions of the substrate 112. Are formed respectively.

Meanwhile, as shown in FIG. 11, the wedge unit 150 includes a wedge portion 151 and a key insertion portion 152 formed at a rear end of the wedge portion 152, and a wedge insertion from a rear end of the main housing 130. Inserted into space 1104.

The wedge 151 serves to push up the stopper 147 and the elastic part 142 of the locking unit 140 upward, and may be a plate formed in a direction parallel to the substrate 112.

The wedge 151 is inserted into the wedge insertion space 1104 formed between the plug housing 111 and the locking unit 140 and has a height corresponding to the wedge insertion space 1104.

In addition, the wedge 151 preferably has a length enough to reach the lower end of the lock unit 140 when the wedge 151 is pushed as far as the inside of the plug housing 111. This is because the wedge 151 can strongly support the state in which the spike 145 of the locking unit 140 is pushed up.

In the center of the wedge 151 may be formed a rectangular engaging hole 153 having a long side in the longitudinal direction. A stopper 147 protruding downward from the locking unit 140 is inserted into the locking hole 153. When the stopper 147 is inserted into the locking hole 153, the stopper 147 is caught by the front end wall of the locking hole 153 even when the wedge unit 150 is pulled backward, so that the wedge unit 150 is held in the main housing 130. You will not be able to remove it completely outside of. In order to completely remove the wedge unit 150, the locking hole 153 may be omitted.

Meanwhile, specific shapes of the locking hole 153 and the stopper 147 may be different from those shown in the drawings. In addition, if the stopper 147 may be caught, the locking hole 153 may be formed as a groove instead of a through hole.

The key insertion portion 152 is a portion into which the key unit 400 for inserting the wedge unit 150 to the rear end is inserted. The key hole 155 is formed on the upper surface of the key inserting portion 152 and the rear end of the key hole 115 is opened. Guide walls 1551 are formed on both sides of the key hole 115 in parallel with each other, and a locking groove 1555 is formed at the tip of the guide wall 1551. The locking groove 1555 is a portion into which the locking protrusion 412 formed in the fixing key 410 of the key unit 400 to be described later is inserted.

In addition, a plurality of pattern protrusions 1552 are formed in the keyhole 115 in the longitudinal direction from the tip wall 1553 to the rear end thereof, and the pattern protrusions 1552 are formed when the key unit 400 described later enters the key unit ( It meshes with the pattern groove 422 of 400.

The height of the tip wall 1553 formed at the tip end of the key hole 115 is preferably equal to or higher than the thickness of the fixing key 410 and the moving key 420 of the key unit 400.

On the other hand, the portion corresponding to the position where the stopper 147 of the fixing unit 140 is moved in the tip wall 1553 is used as the locking step 157 that the tip of the stopper 147 is caught. To this end, the pattern protrusion 1552 formed at a position corresponding to the locking step 157 should be spaced apart from the front end of the locking step 157. In addition, an inclined surface 158 corresponding to the inclination angle of the stopper 147 may be formed at the tip of the pattern protrusion 1552 spaced in the longitudinal direction from the locking step 157 to avoid interference with the stopper 147.

When the front end of the stopper 147 is caught by the locking jaw 157, the wedge unit 150 cannot move backwards. Therefore, to move the wedge unit 150 backward, the end of the stopper 147 is pushed up. It should not be caught in the locking jaw (157). In the embodiment of the present invention, the stopper 147 caught by the locking step 157 is pushed up to a position higher than the locking step 157 by using the key unit 400 described later.

To this end, the height of the locking step 157 should be smaller than the thickness of the moving key 420 of the key unit 400. Only then, when the moving key 420 enters the lower part of the stopper 147 and pushes up the tip of the stopper 147, the tip of the stopper 147 becomes higher than the locking step 157 so that the wedge unit 150 is connected to the stopper 157. Because you can move backwards without getting caught.

The locking jaw 157 and the locking hole 153 of the wedge unit 150 are disposed along the length direction, and the locking jaw 157 has a height lower than that of other portions of the tip wall 1553, so A concave step 154 may be formed between the engaging holes 153 as shown in the drawing.

Meanwhile, as shown in FIGS. 5 and 6, a protruding portion 159 protruding downward may be formed on the bottom of the wedge unit 150. The protruding portion 159 blocks the wedge unit 150 from moving further by being caught by the catching jaw 132 protruding inwardly from the tip of the main housing 130 when the wedge unit 150 is moved toward the tip side. Do it.

5 and 6, the operation of the port locking device 100 according to the first embodiment of the present invention will be described.

First, FIG. 5 illustrates a state in which the stopper 147 of the locking unit 140 is caught by the front end wall of the locking hole 153 of the wedge unit 150 and is no longer pulled out when the wedge unit 150 is removed backward. will be. In this state, since the wedge portion 151 of the wedge unit 150 is not located below the elastic portion 142 of the locking unit 140, the elastic portion 142 is inclined downward as it is, and thus the spike 145 is It does not protrude above the substrate 112.

In this state, if the wedge unit 150 is pushed toward the front end, the rear end wall of the locking hole 153 is first advanced to lift the stopper 147 of the locking unit 140, and then the wedge 151 is the locking unit. The lower portion of the elastic portion 142 of the 140 is entered.

When the wedge portion 151 enters the lower portion of the elastic portion 142 of the locking unit 140, the elastic portion 142 rises and the spikes 145 form the through portions 113 and 114 formed on the substrate 112. Passes through and protrudes above the substrate 112.

Subsequently, when the stopper 147 of the locking unit 140 is caught by the locking jaw 157 of the wedge unit 150, the wedge unit 150 does not fall backward.

12 to 14, an operation in which the port locking device 100 according to the first embodiment of the present invention is inserted into and fixed to the USB port 10 of a computer will be described. 12 and 13 are longitudinal sectional views in the longitudinal direction, FIG. 12 is a longitudinal sectional view for illustrating the operation of the spike 145, and FIG. 13 is a longitudinal sectional view for illustrating the operation of the stopper 147. 14 is a cross-sectional view in the width direction.

When the port lock device 100 is inserted into the USB port 10 of the computer, as shown in Figs. 12 (a) and 13 (a), the wedge unit 150 should be inserted in the state of being pulled out rearward. . This is because the spike 145 does not protrude to the upper portion of the substrate 112 to be inserted smoothly, and does not cause unnecessary damage to the terminal block 12.

When the port lock device 100 is inserted into the USB port 10 of the computer, the terminal block 12 provided in the USB port 10 is inserted into the terminal block insertion space of the port lock device 100 (1102 of FIG. 5).

The second embodiment of the present invention relates to a port locking device without a gender coupling portion, which will be described in detail below with reference to the accompanying drawings.

FIG. 19 is a perspective view of the port locking device 500 according to the second embodiment, and FIGS. 20 and 21 show a state in which the wedge unit 530 is pulled out and pushed in a state in which the plug housing 510 is removed. The figure shown. 22 is a bottom perspective view of the plug body 520.

As shown in the figure, the port locking device 500 according to the second embodiment of the present invention is a plug housing 510. The plug body 520 enclosed by the plug housing 510, the wedge unit 530 having a key hole 533 formed on the upper surface of the plug body 520, and the lower part of the plug body 520. It includes a locking unit 540 having a spike 545 is raised and lowered by the wedge unit 530.

The plug housing 510 is inserted into the USB port 10 of the computer and has a standard according to the USB standard.

The plug body 520 includes a base 521 having a plurality of through holes 525 and a rear wall 523 protruding upward from the rear end of the base 521.

The base 521 of the plug body 520 is located inside the plug housing 510.

Without coupling protrusion 549 may be inserted. However, this coupling method is an example, and therefore, the coupling structure of the locking unit 540 and the plug body 520 is not limited to that shown in the drawings.

The wedge unit 530 may be fully inserted into the port locking device 500 as shown in FIG. 19 (a), or the rear end of the wedge unit 530 may be inserted into the key hole 533 by the key unit 533. You can also pull it out.

The wedge unit 530 may include a wedge body 531 and a key hole 533 formed at an upper surface of the wedge body 531 and opened to the rear end. The key hole 533 may be formed over the front surface of the wedge body 531 or may be formed only at a portion of the rear end thereof.

When the wedge body 531 is pushed as far as possible into the wedge insertion space 529 formed between the bottom of the plug housing 510 and the locking unit 540, the tip of the wedge body 531 is located at the lower end of the plug body 521. It is desirable to have a length to reach. This is because the wedge body 531 can be strongly supported while pushing up the spike 545 of the locking unit 540.

The key hole 533 is formed inside the guide wall 539 protruding in the longitudinal direction on both sides of the wedge body 531, the tip wall is protruded at the tip of the key hole 533. Accordingly, the key hole 533 is opened to the rear of the wedge unit 530.

In addition, a plurality of pattern protrusions 535 are formed in the longitudinal direction in the key hole 533, and the pattern protrusions 535 are similar to the pattern protrusions 1552 provided in the port locking device 100 according to the first embodiment. When the key unit 400 enters, the key unit 400 is engaged with the pattern groove 422 of the key unit 400. The tip of the pattern protrusion 535 may be in contact with or may be spaced apart from the tip wall of the key hole 533.

The guide walls 539 formed at both sides of the key hole 533 and the tip wall formed at the tip end are preferably equal to or higher than the thickness of the fixing key 410 and the moving key 420 of the key unit 400.

In addition, as described in the first embodiment, the portion corresponding to the position where the stopper 547 of the locking unit 540 moves in the tip wall formed at the tip of the keyhole 533 is the locking step of the tip of the stopper 547. (537).

In addition, the pattern protrusion 535 formed at a position corresponding to the locking step 537 should be spaced apart from the front end of the locking step 537. In addition, in order to avoid interference with the stopper 547, an inclined surface corresponding to the inclination angle of the stopper 547 may be formed at the tip of the pattern protrusion 535 spaced in the longitudinal direction from the locking step 537.

When the tip of the stopper 547 is caught by the locking jaw 537, the wedge unit 530 does not move backwards, and the locking jaw (using the key unit 400) is moved to move the wedge unit 530 backward. The stopper 547 caught in 537 should be pushed up to a position higher than the locking step 537. To this end, the height of the locking step 537 is preferably smaller than the thickness of the moving key 420 of the key unit 400.

The rear end of the wedge unit 530 may be formed with a protrusion 538 protruding downward. The protrusion 538 serves to block the plug housing 510 or the plug body 520 from moving forward when the wedge unit 530 is moved to the front end.
