  The assembly screw 64 is a screw for attaching the holder 40 to the base 30 through the holder 40 and the base 30 from above the holder 40.

  FIG. 3 is a perspective view showing a state when the connector 10 held by the connector holder 1 is connected to the network device 100. The network device 100 is a cable connection device to which the cable 20 is connected. The network device 100 is a hub or a router, for example, and has a female connector 102. The female connectors 102 are arranged in groups of four horizontally arranged in two horizontal rows and two vertical rows. That is, 2 × 2 = 4 groups are provided. Since one group = 4, 4 × 4 = 16 female connectors 102 are provided.

  The four connectors 10 held by the connector holder 1 are pushed toward each group of female connectors 102 and attached to the female connectors 102.

  FIG. 4 is a plan view showing a state when the connector 10 held by the connector holder 1 is connected to the network device 100. In FIG. 4, the group of female connectors 102 is illustrated as the network device 100. Only one connector holder 1 is shown for convenience of illustration.

  5 is a cross-sectional view taken along the line AA in FIG. The first lever 12 is attached to the connector 10 at a first attachment portion 12 a at the base of the first lever 12. As for the 1st lever 12, the 1st press part 12b of the front-end | tip of the 1st lever 12 is pressed. A second pressing portion 52 is disposed on the first pressing portion 12b. Adjacent connectors 10 are separated by a partition wall 46. The female connector 102 is provided with a stopper 104 to which the lever shoulder 14 is caught. Further, the connector 10 is moved in the direction of the arrow and pushed into the female connector 102.

  Next, the operation of the first embodiment of the present invention will be described.

  First, as shown in FIGS. 3 to 5, the connector 10 held by the connector holder 1 faces the female connector 102. Then, the connector 10 is moved together with the connector holder 1 in the direction shown by the arrow in FIG.

  6 is a cross-sectional view taken along line AA when the connector 10 is pushed into the female connector 102 (FIG. 6A) and the connector 10 is attached to the female connector 102 (FIG. 6B).

  First, in the state shown in FIG. 5, the second pressing portion 52 of the second lever (operation means) 50 is pushed. Then, the first pressing portion 12b of the first lever 12 is pressed. Since the second pressing portions 52 cover all the first pressing portions 12 b of the first levers 12 of the four connectors 10, all the first pressing portions 12 b are pressed toward the upper surface of the connector 10. When the connector 10 is pushed into the female connector 102 in this state, the state shown in FIG. In the state shown in FIG. 6A, since the lever shoulder 14 is under the stopper 104, the lever shoulder 14 does not hit the stopper 104 when pushing the connector 10.

  Further, when the connector 10 is pushed into the female connector 102, the pressing of the second pressing portion 52 is stopped. When the first lever 12 is not pushed, as shown in FIG. The lever shoulder 14 enters the female connector 102 more than the stopper 104 and is at the same height as the stopper 104. Therefore, even if the connector 10 is pulled out of the female connector 102 in this state, the lever shoulder 14 is caught by the stopper 104 and cannot be removed. Thereby, the mounting of the connector 10 to the female connector 102 is completed.

  In addition, in the state shown in FIG. 5, although it described that the 2nd press part 52 was pushed, it is not necessary to push the 2nd press part 52 necessarily. When the connector 10 is pushed into the female connector 102 without pushing the second pressing portion 52, the lever shoulder 14 is pushed downward by the stopper 104. When the connector 10 is pushed into the female connector 102, the state shown in FIG. 6B is obtained.

  6B, if the second pressing portion 52 of the second lever 50 is pressed, the first pressing portion 12b can be pressed. Can be removed. However, it is general that the connector 10 is continuously attached to the network device 100 after the installation and maintenance of the network is completed. Therefore, it is better that the connector 10 is not easily disconnected from the network device 100. In addition, if the connection relationship between the connector 10 and the network device 100 is changed by a person other than the network administrator, an unexpected failure may occur in the network. Therefore, it is preferable that a person other than the network administrator does not easily disconnect the connector 10 from the network device 100. For this purpose, it is preferable to use a locking screw 70.

  FIG. 7 is a perspective view showing a state when the locking screw 70 is attached to the connector holder 1. The locking screw (operation preventing member) 70 extends in the direction in which the cable 20 extends to prevent the connector 10 together with the connector holder 1 from being pulled out of the network device 100. The locking screw 70 is pushed into the accommodation hole 44 provided in the second pressing prevention member accommodation portion 42 and is screwed into the connector holder 1. At this time, it is assumed that the attachment of the connector 10 to the female connector 102 is completed.

  As the locking screw 70, a common plus or minus screw may be used. In FIG. 7, a TORX (registered trademark) screw is used. Drivers that can turn TORX (registered trademark) screws are not as popular as plus and minus drivers. Here, the network administrator uses the TORX (registered trademark) driver to screw the locking screw 70 into the connector holder 1. Then, the locking screw 70 cannot be removed from the connector holder 1 without using a TORX (registered trademark) driver. A person other than the network administrator must obtain a TORX (registered trademark) driver, but it is difficult to obtain because it is not widespread. Therefore, it is difficult for a person other than the network administrator to remove the locking screw 70 from the connector holder 1.

  In addition, it is preferable to use not only a TORX (Torx) (registered trademark) screw but also a screw that is not widely used as the locking screw 70. The locking screw 70 may be a screw that can be turned only by a screwdriver that cannot be easily obtained by anyone other than the network administrator.

  FIG. 8 is a cross-sectional view taken along line AA when the locking screw 70 is attached to the connector holder 1. In the locking screw 70, the threaded portion (shaft portion) is screwed into the screw hole 34 (see FIG. 6). The head portion (head) of the locking screw 70 remains in the receiving hole 44. The shaft portion of the locking screw 70 passes through the screw hole 34 and further contacts a part of the holder 40. A protrusion 54 is disposed on the shaft portion of the locking screw 70. The housing hole 44 of the second pressing prevention member housing portion 42 and the screw hole 34 of the first pressing prevention member housing portion 32 are operation preventing member housing portions for housing the locking screw 70.

  In the state illustrated in FIG. 8, the connector 10 cannot be removed from the female connector 102 as in the state illustrated in FIG. Here, it is assumed that a person other than the network administrator presses the second pressing portion 52 of the second lever 50, presses the first pressing portion 12 b, and tries to pull out the connector 10 together with the connector holder 1. Then, the protrusion 54 tries to move downward from the state shown in FIG. If the protrusion 54 moves downward to the state shown in FIG. 6A, the connector 10 together with the connector holder 1 can be pulled out. However, if the protruding portion 54 moves downward, it collides with the shaft portion of the locking screw 70 and the protruding portion 54 cannot be moved downward. Therefore, the second pressing portion 52 of the second lever 50 cannot be pressed completely and the first pressing portion 12b cannot be pressed completely, so that the connector 10 cannot be removed from the female connector 102.

  In the above embodiment, the connector holder 1 is described on the assumption that the four connectors 10 are held together. However, the connector holder 1 only needs to hold a plurality of connectors 10 together. The plurality may be two or more. For example, six, eight, or ten connectors 10 may be held together. Therefore, a case where the connector holder 1 holds eight connectors 10 together will be described below as a modification. In addition, the same number is attached | subjected to the part similar to said embodiment, and description is abbreviate | omitted.

  FIG. 9 is a perspective view showing a state where the connector 10 is held by the connector holder 1 according to the modification. The number of assembly screws 64 is increased from two to three. Further, the number of second pressing prevention member accommodating portions 42 is increased from one to two. When viewed from the side where the cable 20 protrudes from the connector holder 1, between the second cable 20 and the third cable 20 from the left side, and between the second cable 20 and the third cable 20 from the right side. And a second pressing prevention member accommodating portion 42 is provided.

  FIG. 10 is an exploded perspective view of the connector holder 1 according to the modification. The connector holder 1 includes a base 30, a holder 40, a second lever (operation means) 50, and assembly screws 62 and 64. The connector 10 includes a first lever (lock mechanism) 12 and a lever shoulder 14.

  The base 30 has a first pressing prevention member accommodating portion 32 and a screw hole 34. Two first pressing prevention member accommodating portions 32 are provided at positions corresponding to the second pressing preventing member accommodating portion 42, and two screw holes 34 are provided at positions corresponding to the accommodating holes 44. Two protrusions 54 are provided at positions corresponding to the second pressing prevention member accommodating portion 42.

  FIG. 11 is a perspective view showing a state when the connector 10 held by the connector holder 1 according to the modification is connected to the network device 100. The network device 100 is a hub or a router, for example, and has a female connector 102. Eight female connectors 102 are arranged side by side in two horizontal rows and two vertical rows. That is, 2 × 2 = 4 groups are provided. Since one group = 8, 8 × 4 = 32 female connectors 102 are provided.

  FIG. 12 is a perspective view showing a state when the locking screw 70 according to the modification is attached to the connector holder 1. The locking screw 70 is pushed into the accommodation hole 44 provided in the second pressing prevention member accommodation portion 42 and is screwed into the connector holder 1. At this time, it is assumed that the attachment of the connector 10 to the female connector 102 is completed.

  Further, preventing the connector 10 from being pulled out using the locking screw 70 is also effective when the connector holder 1 holds only one connector 10.

  According to the first embodiment of the present invention, four or eight connectors 10 are fixed to the base 30 and the holder 40, which is convenient for transporting a plurality of connectors 10. In addition, when the second pressing portion 52 of the second lever (operation means) 50 is pressed, all the first pressing portions 12b of the first levers 12 of the four or eight connectors 10 can be pressed. As a result, these four or eight connectors 10 can be attached to and detached from the network device 100 at once.

  Moreover, after attaching the connector 10 together with the connector holder 1 to the female connector 102 of the network device 100, the locking screw 70 is screwed into the screw hole 34 of the first pressing prevention member housing portion 32, thereby lowering the protruding portion 54. It can be disabled. As a result, the second pressing portion 52 of the second lever 50 cannot be fully pressed and the first pressing portion 12b cannot be fully pressed, so that the connector 10 cannot be removed from the female connector 102. Therefore, it is possible to prevent the connector 10 from being inadvertently disconnected from the female connector 102.

Second Embodiment In the second embodiment, in the connector holder (connection prevention tool) 1 according to the first embodiment, none of the connectors 10 is connected to the cable 20.

FIG. 13 is a perspective view showing a state in which the connector 10 is held by the connector holder (connection prevention tool) 1 according to the second embodiment of the present invention. FIG. 14 is an exploded perspective view of the connector holder (connection prevention tool) 1 according to the second embodiment of the present invention. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  There are four connectors 10 in total, but none of them are connected to the cable 20. All the connectors 10 are connected to the network device 100 as shown in FIG. However, since the cable 20 is not connected to all the connectors 10, no other network device (different from the network device 100) is connected to all the connectors 10. Thus, all the connectors 10 are non-connecting connectors that are disconnected from other network devices (which are different from the network device 100) (a type of cable connection device to which a cable is connected).

  Other configurations and operations are the same as those in the first embodiment. However, it is preferable to use a locking screw (operation preventing member) 70 as shown in FIG. In addition, unlike a normal connector, the connector 10 may be configured not to include a conductor. The extending direction of the locking screw (operation preventing member) 70 is the same as in the first embodiment. That is, the locking screw 70 extends in the direction in which the cable 20 extends when it is assumed that the cable 20 is attached to the connector 10.

  According to the second embodiment, it is possible to prevent unauthorized connection to a device such as the network device 100 to which a cable is connected.

  For example, it is assumed that there is a female connector 102 to which nothing is connected in the network device 100. Such a female connector 102 is referred to as an empty port. If an empty port is left unattended, it cannot be prevented that an UTP cable or pin is illegally connected to the empty port. An illegally connected UTP cable or pin is connected to another network device used by an unauthorized person. An unauthorized person can illegally acquire information transmitted in a network connected to a network device by using another network device. In this way, network security is compromised.

  Here, the connector 10 held by the connector holder (connection prevention tool) 1 is connected to the empty port. Further, the locking screw 70 is attached to the connector holder (connection prevention tool) 1.

  Then, since the connector 10 is connected to the empty port, a UTP cable or pin cannot be connected to the empty port. Accordingly, unauthorized connection to the network device 100 can be prevented.

  Since the locking screw 70 is attached to the connector holder (connection prevention tool) 1, the connector 10 cannot be removed from the empty port.

Third Embodiment A third embodiment is the connector holder (connection prevention tool) 1 according to the second embodiment, in which one connector 10 is connected to one end of the cable 20, but the cable 20 The other end of the connector is not connected to the connector 10.

  FIG. 15 is a perspective view showing a state where the connector 10 is held by the connector holder (connection prevention tool) 1 according to the third embodiment of the present invention. FIG. 16 is an exploded perspective view of a connector holder (connection prevention tool) 1 according to the third embodiment of the present invention. Hereinafter, the same parts as those of the second embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  There are four connectors 10 in total, but the third connector from the left end is not connected to the cable 20. One of the right ends of the connectors 10 is connected to one end of the cable 20. However, nothing is connected to the other end of the cable 20, and the connector 10 is also not connected. For example, a short cable 20 is connected to one connector 10 at the right end. In this case, the disconnected cable 20 may be connected to one connector 10 at the right end.

  The connector 10 from the left end to the third is a non-connecting connector as in the second embodiment. One connector 10 on the right end is also a non-connected connector that is disconnected from another network device (different from the network device 100) because nothing is connected to the other end of the cable 20.

  Other configurations and operations are the same as those of the second embodiment.

  According to the third embodiment, it is possible to prevent unauthorized connection to a device such as the network device 100 to which a cable is connected.

  For example, the connector 10 held by the connector holder (connection prevention tool) 1 is connected to an empty port of the network device 100. Further, the locking screw 70 is attached to the connector holder (connection prevention tool) 1.

  Then, since the connector 10 is connected to the empty port, a UTP cable or pin cannot be connected to the empty port. Accordingly, unauthorized connection to the network device 100 can be prevented.

  Since the locking screw 70 is attached to the connector holder (connection prevention tool) 1, the connector 10 cannot be removed from the empty port.

  In the second embodiment and the third embodiment, it is assumed that the network device 100 has four free ports. However, assume that the network device 100 has three empty ports and one female connector 102 to be connected to another network device (which is a cable connection device). In such a case, it is preferable to apply the modification of the third embodiment.

  In the modification of the third embodiment, another network device is connected to the other end of the cable 20 to which one connector 10 on the right end is connected. One connector 10 at the right end is a connection connector connected to another network device. According to such a modification, unauthorized connection to the network device 100 via three empty ports can be prevented. In addition, communication between the network device 100 and another network device can be performed via one female connector 102.
