It is configured to be detachably attached to a LAN cable connector (hereinafter simply referred to as a connector) 106 that is inserted into 104 and latches the inserted state.
As shown in FIG. 1, the lock assembly 10 is locked by a lock 108 in the assembled state. As shown in FIG. 2, the connector assembly 106 is attached to the connector 106. The connector 106 is configured such that the connector 106 can be removed from the insertion port 104 in a state where the insertion state into the insertion port 104 is locked and removed from the connector 106. Then, by locking the insertion state of the connector 106 into the insertion port 104 in this way, the movement of the PC 102 from its installation location is substantially prohibited, and the PC 102 can be prevented from being stolen. ing.
The lock assembly 10 is basically provided so as to be separable in the circumferential direction, and in a state where the lock assembly 10 is assembled to each other, the lock assembly 10 surrounds the outer periphery of the connector 106 in a substantially close contact state. Movement along the axial direction with respect to the connector 106 in a state of being formed integrally with the second enclosures 12 and 14 and the first enclosure 12 so as to surround the outer periphery of the connector 106 The upper surface 106A of the connector 106 (here, in a state of being integrally formed on the second surrounding body 14 and surrounding the outer periphery of the connector 106). The upper surface is a surface opposite to the bottom surface 106B from which a large number of terminals are exposed.) A restriction as a restriction means for restricting the movement of the latch flapper 110 in the latch release direction. It is constituted by a 18.
Here, as shown in FIGS. 3 to 6, the first enclosure 12 is formed in a substantially U shape when viewed from the front, and more specifically, the bottom surface 106 </ b> A of the connector 106 (here, the bottom surface refers to this). A bottom surface 12A disposed in a state corresponding to the surface of the terminal 12A, and a first edge erected from one side edge along the axial direction of the bottom portion 12A. The upright piece 12B and the second upright piece 12C raised from the other side edge, and the rear edge along the direction perpendicular to the axial direction of the bottom portion 12A (here, the front means the direction toward the tip of the LAN cable 100) The term “rear” refers to a direction opposite to the front.) The third upright piece 12D is integrally formed with the third upright piece 12D.
Further, as shown in FIG. 3, a hook groove 12E through which the hook protrusion 14A of the second surrounding body 14 is inserted from the lateral direction penetrates in the thickness direction above the first upright piece 12B. It is formed in a state. The other upright piece 12C is set higher than the upright piece 12B, and one lock hole 12F into which the lock rod 108A of the lock 108 is inserted is formed in the raised portion. Further, the second upright piece 12C is engaged with the locking groove 14B of the second surrounding body 14 in a nested state at a position (that is, the same height position) facing the above-described hook groove 12E. The locking groove 12G is formed in a state extending from the rear end edge forward by about a half width.
The above-described locking projection 16 is defined by the above-described third upright piece 12D. That is, as shown in FIG. 2, the locking protrusion 16 is configured to be locked in one of the groove portions 106 </ b> C formed in the rear portion of the connector 106 in a state assembled to the connector 106. In this locked state, movement along the axial direction of the first surrounding body 12 (therefore, the entire lock assembly 10) is prohibited.
Further, as shown in FIGS. 7 to 9, the second surrounding body 14 described above is formed in a substantially L shape in a front view, and more specifically, a plate-like main body 14C and the first of the main body 14C. For a hook that extends outward in the width direction from a side edge on the same side as one side edge of one enclosure 12 and is set so as to be fitted in a hook groove 12E of the first enclosure 12 A protrusion 14A, an upright piece 14D that stands up from the same side as the other side edge of the first enclosure 12 of the main body 14C, and a protruding piece 14E that protrudes forward from the front edge of the main body 14C are integrated. Is formed. In the first embodiment, the protruding piece 14E is set so as to function as the restricting piece 18 described above.
Further, as shown in FIG. 8, the upright piece 14D is formed with the other lock hole 14F set so as to communicate with the lock hole 12F in a state assembled with the first enclosure 12. A locking groove 14B, which engages with the locking groove 12G described above in a nested state, extends from the front edge toward the rear by about a half width at the edge of the main body 14C on the side where the standing piece 14D stands. It is formed in the state.
An assembly procedure for assembling the first and second enclosures 12 and 14 configured as described above will be described with reference to FIGS. 10 to 12.
First, as shown in FIG. 10, the second enclosure 14 is assembled to the first enclosure 12 from the rear. In this case, the hook protrusion 14 </ b> A of the second enclosure 14 is located immediately inside the first upright piece 12 </ b> B of the first enclosure 12, and the hook protrusion 14 </ b> A of the first enclosure 12 is It is assembled in the state where it is at the same height as the hook groove 12E. Accordingly, the standing piece 14D of the second surrounding body 14 is inevitably positioned outside the second standing piece 12C of the first surrounding body 12, and the engagement of the second surrounding body 14 is established. The stopping groove 14B and the locking groove 12G of the first surrounding body 12 are engaged with each other in a nested manner.
By assembling the second enclosure 14 to the first enclosure 12 from the rear in this way, as shown in FIG. 11, the hook projection 14A is positioned directly inside the hook groove 12E, and The locking grooves 12G and 14B are engaged with each other in a nested manner.
Thereafter, the second enclosure 14 is moved relative to the first enclosure 12 so as to be pushed inward along the width direction thereof. As a result, as shown in FIG. 12, the hook protrusion 14A is fitted in the hook groove 12E, and the second upright piece 12C and the upright piece 14D are overlapped with each other and formed with each other. The lock holes 12F and 14F communicate with each other. Then, the lock rod 108A of the lock 108 is simultaneously inserted into the lock holes 12F and 14F communicating with each other. In this way, as shown in FIGS. 13 to 15, the lock assembly 10 is configured to be separable from each other.
In the description of the assembly procedure described above, the relationship with the connector 106 to which it is assembled has been ignored. However, the locking assembly 10 of this first embodiment is assembled to the outer periphery of the connector 106. Next, referring to FIG. 2 again, the procedure for assembling the locking assembly 10 to the connector 106 will be described. In the following description, the description of the assembling procedure of the locking assembly 10 has already been given and will be omitted.
First, the first enclosure 12 is attached to the connector 106 so as to surround the three surfaces (that is, both side surfaces and the bottom surface) of the connector 106. In this state, the bottom portion 12 </ b> A of the first enclosure 12 faces the bottom surface of the connector 106. In this state, the locking protrusion 16 (that is, the third upright piece 12D) of the first enclosure 12 is further inserted into the groove portion 106C formed at the rear of the connector 106, whereby the first The movement along the axial direction of the surrounding body 12 is prohibited.
Thus, after attaching the 1st enclosure 12 in the state which surrounds the three surfaces of the connector 106, the 2nd enclosure 14 is covered with the 1st enclosure so that the main body 14C may cover the upper surface of the connector 106. 12 is attached. In the state where the second enclosure 14 is assembled to the first enclosure 12 so as to surround the outer periphery of the connector 106 in this way, as shown in the figure, the restriction integrally attached to the second enclosure 14 The piece 18 (that is, the protruding piece 14E) extends to the vicinity of the proximal end portion of the flapper 110 of the connector 106.
In this way, as will be described in detail later, even if the flapper 110 is pushed in to release the latched state of the insertion port 104, the regulating piece 18 is not attached to the flapper 110 in the state where the locking assembly 10 is assembled. Since this extends to the vicinity of the proximal end portion of this, this becomes a hindrance, the pushing operation is hindered, and the latched state to the insertion port 104 cannot be released. That is, the lock assembly 10 does not release the latch of the connector 106 inserted into the insertion port 104, in other words, the connector 106 is locked to the insertion port 104.
As described above, the locking assembly 10 according to the first embodiment is assembled in a state of surrounding the connector 106 so that the movement of the connector 106 in the pushing direction of the flapper 110, that is, the latch in the inserted state is prevented. Movement in the releasing direction is prohibited, and the connector 106 is locked to the insertion port 104. As a result, even if the connection state of the LAN cable 100 is not released and the PC 102 to which the LAN cable 100 is connected is forcibly moved from the installation location, it is impossible to move the connection without disconnecting the LAN cable 100. This makes it possible to reliably prevent the PC 102 from being stolen.
16 and 17, the insertion operation of the connector 106 into the insertion port 104 in a normal state (that is, in a state where the lock assembly 10 of the first embodiment is not used) is described. explain.
First, a flapper 110 is attached to the upper surface 106A of the connector 106 so as to be elastically pushed and biased. Specifically, as shown in FIG. 16, the tip of the flapper 110 is attached to the front edge of the upper surface 106A of the connector 106. It is attached integrally.
Here, the base end portion 110A of the flapper 110 is set to be wide, and the tip end portion 110B following the base end portion 110A is set to be narrower than the base end portion 110A. That is, the flapper 110 has a two-stage structure in the width direction, and has a step in the middle.
On the other hand, as shown in FIG. 17, the insertion port 104 is formed with a first groove 104A into which the wide base end portion 110A of the flapper 110 can be inserted at the upper edge of the opening. On the upper bottom surface of the groove portion 104A, a second groove portion 104B into which the wide base end portion 110A of the flapper 100 cannot be inserted and only the narrow end portion 110B can be inserted is formed. The thickness along the axial direction of the second groove 104B is set to be thin, and a so-called shoulder for locking is defined.
Since the insertion port 104 has such a structure, as shown in FIG. 16 again, when the connector 106 is inserted into the insertion port 104, the wide base end portion 110A of the flapper 110 is While passing through the first groove 104A, it is gradually pushed down on the upper bottom surface. Then, when the stepped portion that transitions to the tip portion 110B of the flapper 110 passes through the shoulder portion described above, the narrow tip portion 110B enters into the second groove portion 104B by its own elastic force. Thus, the step portion of the flapper 110 is locked to the shoulder portion of the insertion port 104. Due to such a locking relationship between the stepped portion and the shoulder portion, the insertion state of the connector 106 into the insertion port 104 is latched so that it cannot be removed.
On the other hand, when removing the connector 106 from this inserted state, the flapper 110 is pushed down against its own elastic force. By this depression, the locking state between the stepped portion and the shoulder portion described above is released, and the connector 106 is pulled out from the insertion port 104. That is, the latched state of the connector 106 with respect to the insertion port 104 is released. When the connector 106 is pulled out from the insertion port 104 in this released state, the connector 106 is pulled out from the insertion port 104.
In the configuration of the connector 106 and the insertion port 104 configured as described above, by using the locking assembly 10 of the first embodiment, the second enclosure 14 of the assembled locking assembly 10 is used. The integrally formed restricting piece 18 obstructs the push-down movement of the flapper 110, thereby preventing the release of the latch due to the push-down of the flapper 110. As a result, the connector 106 is maintained in a state of being inserted into the insertion port 104 (that is, locked), and the connector 106 is reliably prohibited from being extracted from the insertion port 104.
As described above in detail, using the locking assembly 10 according to the first embodiment, the insertion state of the connector 106 inserted into the insertion port 104 of the PC 102 into the insertion port 104 is determined. By locking, it is possible to effectively stop the PC 102 at its installation location, and it is effective from theft, including easily moving the PC 102 to another location. Can be prevented. In other words, in the first embodiment, the PC 102 is separated from the casing of the PC 102 as compared with the conventional case where the PC 102 is stopped at the installation place by using a connecting device such as a lock wire. By locking (prohibiting) the removal of the connector 106 already connected to the PC 102 without adhering the members, an anti-theft effect can be obtained, and its usefulness is extremely high.
In particular, in the state where the lock assembly 10 according to the first embodiment is used, a person who wants to take away the PC 102 (forcibly move it from the installation location) can only cut the LAN cable 100. Is something that disappears. In this regard, even when a conventional connector such as a lock wire is used, similarly, if the connector such as a wire is cut using a powerful cutter or the like, the connection state is released, and the PC 102 Can be taken away.
Here, the conventional connector such as a wire merely mechanically connects the PC 102 to a fixed place, and the disconnection of the connector such as a wire cannot be detected at all. On the other hand, in the state where the locking assembly 10 according to the first embodiment is used, since the connection state via the LAN cable 100 is locked, the LAN cable 100 is disconnected as described above. However, there is no means for releasing the connected state, and once this LAN cable 100 is cut, for example, the metal cutter blade comes into contact with the cord in the LAN cable 100 and short-circuits, This short phenomenon is detected by the server on the other side to which the LAN cable 100 is connected, and the LAN cable 100 is not intended in this server. In which a state of disconnection may be recognized. Further, even when the short phenomenon is not detected, the cord is opened in the LAN cable 100 after being cut, and this open state is detected by the server. Similarly, in this server, In this state, unintentional disconnection of the LAN cable 100 can be recognized.
That is, by using the locking assembly 10 of the first embodiment, not only can the PC 102 be stolen, but also if it is stolen, the fact that it has been stolen can be detected immediately. As a result, so-called security can be improved.
On the other hand, the in-house business PC 102 is normally connected to a network, and therefore, the LAN cable 100 is connected to the connector receiving port 104 on the rear surface of the PC 102 via the connector 106. It is actually used in the state where it is plugged in. Here, when the user tries to access another network in consideration of his own convenience in the state of being connected to the network in this way, the connector 106 is simply removed and the LAN cable connected to the other network is simply removed. You can reconnect the connector. Such a user's selfishness is not desirable on the company side, and it is definitely desired to prohibit it.
However, an effective restraining means for such unplugging and unplugging of the connector 106 has not existed conventionally, but by using the locking assembly 10 according to the first embodiment, In addition to the anti-theft effect described above, it is possible to further prevent the connection of the connector 106 and prevent the connection to other networks.
Furthermore, when the PC 102 used for business use in the company is connected to the server via the network, it is strictly prohibited to import business data into the personal use PC. It is. However, the connector 106 inserted into the insertion port 104 of the business-use PC 102 is in a state where it can be easily removed. Therefore, it is replaced with a personal-use PC, and the personal-use PC is transferred to the server. There is a real possibility that business data will be taken in by being accessed.
In response to such a concern, by using the locking assembly 10 according to the first embodiment, the server 106 can be reliably prevented from being replaced without permission, in addition to the antitheft effect described above. The personal computer can be effectively prevented from being connected to the server, and the effect of maintaining the data in the server can be further exhibited.

The first enclosure 212 is assembled such that the second enclosure 214 assembled from above in the drawing partially overlaps with each standing piece. That is, the lock hole 212F of the first upright piece 212B of the first enclosure 212 and the lock hole 214F of the first upright piece 214B of the second enclosure 214 are in the same position, and the first The lock hole 212G of the second upright piece 212C of the enclosure 212 and the lock hole 214G of the second upright piece 214C of the second enclosure 214 are assembled at the same position.
Thereafter, with the plurality of connectors 206 inserted into the plurality of insertion ports 204, the bottom 212A of the first enclosure 212 contacts the bottom 206B of the connector 206, and the first enclosure 212 first The upright piece 212B and the second upright piece 212C are configured to be located further outside the two outer connectors 206 out of the five connectors 206 inserted into the five insertion ports. In this case, the locking recess 216 provided in the third upright piece 212 </ b> D of the first surrounding body 212 is in a state of biting into the groove 206 </ b> C at the base of the connector 206. Further, the protruding piece 214E of the second enclosure 214 is a latch flapper so that the five connectors 206 are inserted into the five insertion ports 204 and are in contact with the upper surface 206A of each connector 206. Inserted under 210. In this state, the first enclosure 212 and the second enclosure 214 constituting the lock assembly 210 are configured as shown in FIG. 26 (however, in FIG. 26, the five connectors 206 are omitted). Each of the connectors 206 is locked while being inserted into the insertion slot 204 by the locking of the locks 208 and 209.
27 and 28, the connector 206 is inserted into the plurality of insertion openings 204 in a normal state (that is, in a state where the lock assembly 210 of the second embodiment is not used). The operation will be described.
FIG. 27 is a sectional view of the insertion port 204 provided in the connector 206 and the hub 202. First, a flapper 210 that is elastically pushed and biased is integrally attached to the front end edge of the upper surface 206A of the connector 206.
The flapper 210 has a base end portion 210A set to be wide, and a tip end portion 210B following the base end portion 210A is set to be narrower than the base end portion 210A. That is, the flapper 210 has a two-stage structure in the width direction, and has a step in the middle.
FIG. 28 is a perspective view showing a plurality of insertion ports 204 provided in the hub 202. A first groove portion 204A into which the wide base end portion 210A of the flapper 210 can be inserted is formed at the upper edge of the opening portion of the insertion port 204, and a flapper is formed on the upper bottom surface of the first groove portion 204A. A second groove portion 204B is formed in which the wide base end portion 210A of 210 cannot be inserted and only the narrow distal end portion 210B can be inserted. In addition, the thickness along the axial direction of the second groove portion 204B is set to be thin, and a so-called locking shoulder portion is defined.
Since the insertion port 204 has such a structure, as shown in FIG. 27, when the connector 206 is inserted into the insertion port 204, the wide base end portion 210A of the flapper 210 is It is gradually pushed down on the upper bottom surface while passing through the groove portion 204A. Then, when the stepped portion transitioning to the tip portion 210B of the flapper 210 passes through the shoulder portion described above, the narrow tip portion 210B enters into the second groove portion 204B by its own elastic force. Thus, the step portion of the flapper 210 is locked to the shoulder portion of the insertion port 204. By such a locking relationship between the stepped portion and the shoulder portion, the insertion state of the connector 206 into the insertion port 204 is locked so that it cannot be removed.
On the other hand, when pulling out the connector 206 from this inserted state, the flapper 210 is pushed down against its own elastic force. By this depression, the above-described locking state between the stepped portion and the shoulder portion is released, and the connector 206 can be pulled out from the insertion port 204. That is, the latch state of the connector 206 to the insertion port 204 is released. When the connector 206 is pulled out from the insertion port 204 in this released state, the connector 206 is pulled out from the insertion port 204.
In the configuration of the connector 206 and the insertion port 204 configured as described above, when the locking assembly 210 of the second embodiment is assembled, a protruding piece 214E formed integrally with the second surrounding body 214 is formed. Therefore, the push-down movement of the flapper 210 is obstructed, and the release of the latch by the push-down of the flapper 210 is prevented. As a result, the state where the connector 206 is inserted into the insertion port 204 is maintained (that is, locked), and the connector 206 is reliably prohibited from being removed from the insertion port 204.
As described above in detail, the connector 206 inserted into the insertion port 204 of the hub 202 is inserted into the insertion port 204 using the locking assembly 210 according to the second embodiment. Since the LAN cable 100 can be effectively locked to the hub 202, it is possible to effectively prevent the PC connected to the LAN cable 100 from being taken together with the LAN cable.
In a state where the lock assembly 210 according to the second embodiment is used, a person who wants to take away the PC (forcibly move it from the installation location) can only cut the LAN cable 100. Is. However, once this LAN cable 100 is cut, for example, a metal cutter blade comes into contact with the cord in the LAN cable 100 and short-circuits, and this short phenomenon is caused by the other side to which the LAN cable 100 is connected. And the server is in a state where unintentional disconnection of the LAN cable 100 can be recognized. Further, even when the short phenomenon is not detected, the cord is opened in the LAN cable 100 after being cut, and this open state is detected by the server. Similarly, in this server, In this state, unintentional disconnection of the LAN cable 100 is recognized.
As described above, by using the locking assembly in the second embodiment, it is possible to effectively prevent the PC from being stolen, including easily moving the PC to another location. In other words, in the second embodiment, the PC is not separated from the PC housing in comparison with the conventional case where the PC is stopped at the installation location by using a connecting device such as a wire for locking. By locking (prohibiting) the removal of the connector 206 already connected to the hub 202 without adhering any members, the PC can have an anti-theft effect, and its usefulness is extremely high. It is.
Further, in the second embodiment, by inserting the plurality of LAN cable connectors 206 inserted into the hub into the insertion port 204 at the same time, so that the LAN cable cannot be removed from the hub. Also, it is possible to expect the effect of preventing troubles such as an intranet system failure caused by intentionally or mistakenly disconnecting the LAN cable connected to the hub or intentionally or mistakenly inserting a different LAN cable.
That is, by using the lock assembly 210 of the second embodiment, not only can the PC 102 be prevented from being stolen, but also local area networks and intranet troubles can be prevented, and security can be improved. It can be done.
Needless to say, the present invention is not limited to the configuration of the second embodiment described above and can be variously modified without departing from the gist of the present invention.
For example, in the above-described embodiment, the case where two locks are used has been described. However, the present invention is not limited to this configuration, and the number of locks is set to one by devising the shapes of the first enclosure and the second enclosure. It goes without saying that it is possible.
In the second embodiment, the number of hub insertion ports is five and the number of LAN cable connectors is five. However, it goes without saying that the number is not limited to this number. .
