  FIG. 4 is a diagram showing details of the thin plate portion 13. FIG. 4A is a front view of the thin plate portion 13, and FIG. 4B is a side view of the thin plate portion 13.

  In the vicinity of the center portion of the fixed portion 13A of the thin plate portion 13, a fool hole 13C is provided. Moreover, the thickness of the regulation piece 13B is formed thicker than that of the fixed portion 13A, so that the locked state of the locking piece 14 can be reliably regulated.

  In addition, the material of the dummy terminal main body 12, the thin plate portion 13, and the locking piece 14 is easy to be molded and inexpensive, and synthetic resin having insulation and elasticity is mainly used. For example, ABS ( An acrylonitrile / butadiene / styrene resin, an AAS (acrylic rubber / acrylonitrile / styrene) resin, a PC (polycarbonate) resin, or the like is used.

  Next, the manner in which the dummy terminal 10 is inserted into the connector terminal insertion port of the hub 101 and the locking state of the dummy terminal 10 is locked will be described with reference to FIGS.

  The dummy terminal 10 of the present invention is inserted into the connector terminal insertion port of the hub 101 for connecting a large number of LAN cable connector terminals to connect a plurality of computers as communication terminals, and locks or releases the state. It is attached to do.

  FIG. 5 is a perspective view showing the connector terminal insertion port 104 of the hub 101 into which the dummy terminal 10 is inserted. 6 shows a state before the dummy terminal 10 is inserted into the connector terminal insertion port 104 of the hub 101. FIG. 7 shows a state where the dummy terminal 10 is inserted into the connector terminal insertion port 104. The inserted state shows a locked state.

  As shown in FIG. 5, the plurality of connector terminal insertion ports 104 are formed with first groove portions 104A into which the wide flexible portions 14B of the locking pieces 14 can be inserted at the upper edges of the openings, On the upper bottom surface of the groove portion 104A, a second groove portion 104B in which the wide bending portion 14B of the locking piece 14 cannot be inserted and only the narrow locking release portion 14D can be inserted is formed. Note that the connector terminal locking portion is formed by a step between the first groove portion 104A and the second groove portion 104B. That is, the length of the first groove portion 104A in the dummy terminal insertion direction is set to be short, and when the dummy terminal reaches a position where it is completely inserted into the connector terminal insertion port, the locking portion 14C is caused by the elastic force of the flexible portion 14B. However, the dummy terminal body 12 is locked to the connector terminal by entering the connector terminal locking portion formed by the step in the depth direction between the first groove portion 104A and the second groove portion 104B. .

  Next, a state in which the dummy terminal 10 is inserted into the connector terminal insertion port 104 of the hub 101 and the insertion state is locked will be described with reference to FIGS. 6 and 7. In FIG. 6, since the push screw 30 is loosened, the thin plate portion 13 is not completely attached to the dummy terminal body 12, and the locking piece 14 is not in a restricted state. In this state, when the dummy terminal 10 is inserted into the connector terminal insertion port 104 from the fixing portion 14A side of the locking piece 14, the bent portion 14B of the locking piece 14 is elastically pushed in and the first groove portion 104A. Is inserted.

  By inserting the dummy terminal 10, the wide flexible portion 14B of the locking piece 14 is gradually pushed down on the upper bottom surface of the locking piece 14 while passing through the first groove portion 104A. Then, when the locking portion 14C passes through the connector terminal locking portion described above, it enters the connector terminal locking portion by falling into the second groove portion 104B having a narrow width by the elastic force of the bending portion 14B. Will be locked. Due to the locking relationship between the step in the width direction between the bent portion 14B and the locking release portion 14D and the step in the depth direction between the first groove portion 104A and the second groove portion 104B, the connector of the dummy terminal 10 is used. The insertion state into the terminal insertion port 104 is locked so that it cannot be removed.

  The push screw 30 is tightened in the insertion state in which the dummy terminal 10 is locked in the connector terminal insertion port 104 so as not to be extracted. Since the thin plate portion 13 is provided with a hole 13C through which the push screw 30 is passed, the fixing portion 13A of the thin plate portion 13 is fixed to the front surface portion 12D of the dummy terminal body 12 by this tightening. By fixing the fixing portion 13A, the restricting piece 13B restricts the movement of the locking release portion 14D of the locking piece 14, and the dummy terminal 10 is inserted into the connector terminal insertion port 104 as shown in FIG. It will be maintained (ie locked). In this way, by inserting the dummy terminal of the present invention into the connector terminal insertion port that is not connected but should not be used in advance, the dummy terminal of the present invention is in a state of prohibition of extraction. It is possible to prevent the connector terminal from being inserted.

  On the other hand, in order to extract the dummy terminal 10 from this insertion prohibition state, first, the fixing screw 13 is loosened to release the fixing state of the fixing portion 13A of the thin plate portion 13, and the movement is restricted by the restricting piece 13B. The locked release portion 14D is brought into a movable state. Next, the locking release portion 14D is pushed down against its own elastic force. By this depression, the locked state between the step in the width direction between the bent portion 14B and the unlocking portion 14D and the step in the depth direction between the first groove 104A and the second groove 104B is released. The dummy terminal 10 can be extracted from the connector terminal insertion port 104.

  In the first embodiment, the type of the push screw 30 is not particularly specified, but a normal screw may be used or a special screw shown in FIG. 8 may be used.

  Since the dummy terminal 10 is inserted into the connector terminal insertion port, there is an effect of preventing accidental accidents in which another connector terminal is erroneously inserted. However, it is easy to loosen the push screw 30 with a normal screw, so that the dummy terminal 10 is mistakenly removed from the connector terminal insertion port and inserted into the connector terminal insertion port where another connector terminal should not be inserted. It is not effective against serious accidents.

  FIG. 8 is a diagram illustrating an example in which the push screw 30 is a special screw. The push screw 30 includes a screw head 30A and a screw portion 30B. FIG. 8A shows an example of an ultra-low head screw, FIG. 8B shows an example of a countersunk screw of a countersunk screw type, and FIG. 8C shows an example of a tamper-proof screw of a round screw type. In any of these, a special three-dimensional recess is formed in the screw head 30A for attaching and detaching the screw, and the push screw 30 can be removed by turning the screw head 30A with a dedicated tool.

  By using a special screw as shown in FIG. 8 as the push screw 30, the dummy terminal of the present invention can be identified, and the connector terminal insertion port that may be used for each administrator must not be identified or used. It is possible to identify the connector terminal insertion port. That is, in the special screw as shown in FIG. 8, it is necessary to use a dedicated tool for the attachment and detachment. For example, in a special connector terminal insertion port used only by a specific administrator, FIG. If the special screw shown in the figure is used as the push screw 30 and only a specific administrator can use the special tool required for attaching / detaching the special screw shown in FIG. Only the administrator can use it. In this way, by using the special screw as the push screw 30, it is possible to prevent an accident that the dummy terminal 10 is accidentally pulled out from the connector terminal insertion port.

<Modification>
In the first embodiment, when inserting the dummy terminal 10 into the connector terminal insertion port 104, it has been described that the push screw 30 is inserted in a loosened state, but the present invention is not limited to this method. As shown in the dummy terminal 10 of FIG. 7, the fixing screw 13 is fastened to fix the fixing portion 13A to the front surface portion 12D, and the restriction piece 13B remains in a state where the movement of the locking release portion 14D of the locking piece 14 is restricted. The connector terminal insertion port 104 can be inserted. This is because, even when the locking piece 14 is in a restricted state, when the dummy terminal 10 is inserted into the connector terminal insertion port 104, the bent portion 14B of the locking piece 14 is elastically pushed into the locking portion. This is because 14C can pass through the connector terminal locking portion. Since the dummy terminal 10 can be inserted into the connector terminal insertion port 104 with the push screw 30 tightened in this way, the dummy terminals prepared in advance are sequentially inserted into the connector terminal insertion port that should not be used. This is effective for erroneous connection of connector terminals.
