  Next, the adapter 3 will be described with reference to FIGS.

  4A and 4B are perspective views of the adapter 3 of the LAN cable connection device 1, where FIG. 4A is an oblique front view and FIG. 4B is an oblique rear view. FIG. 5 is a schematic perspective view showing the internal structure of the rotating part of the adapter 3 in FIG. FIG. 6 is a side sectional view of the adapter 3 of the LAN cable connection device 1.

  The adapter 3 is detachably attached to the connector 101 of the LAN cable 100. As shown in FIGS. 4A and 4B, the adapter main body 31, the lock portion 32, and the lock portion covering the outer periphery of the connector 101 are provided. A conductive portion 32a that is disposed at the tip of the base 32 and can be electrically connected to the switch 24 of the base 2, a rotation shaft 33, and an engagement recess 311 that engages with the engagement protrusions 23a and 23b. Prepare.

  The adapter main body 31 is a substantially rectangular parallelepiped covering the outer periphery of the connector 101 on the LAN cable 100 side, and is a hollow case having a U-shaped cross section, and is formed to be detachable from the connector 101. The adapter body 31 is formed of an electrical insulator such as a synthetic resin. The adapter main body 31 is formed with a connector opening 312 and a cable opening 313. The connector opening 312 has a size and shape (substantially rectangular parallelepiped) that can accommodate the connector 101. The cable opening 313 is an opening through which the LAN cable 100 is passed in order to accommodate the connector 101 in the adapter main body 31, and is formed on a surface opposite to the connector opening 312 (hereinafter referred to as “back surface”). And a second opening 313b formed in a surface (hereinafter referred to as “bottom surface”) opposite to the surface on which the lock portion 32 is installed. The first opening 313a is formed in a groove shape from the approximate center of the back surface toward the bottom surface, and has a width that allows the LAN cable 100 to be inserted. On the other hand, the second opening 313b is formed in a groove shape that bisects the bottom surface from the side where the bottom surface and the back surface intersect to the side where the connector opening 312 intersects, and the width is the same as that of the first opening 313a. In addition, the size is such that the LAN cable 100 can be inserted.

  The lock part 32 is formed in a substantially L shape or a bowl shape by two pillars 321 and a plate 322 disposed on the pillar 321 so as to be orthogonal to the pillar 321, and is rotated. It is disposed on the upper surface portion of the adapter main body 31 via the shaft 33. The lock portion 32 is connected to a rotation shaft 33 described later by a pillar, and can be tilted in the advancing / retreating direction of the connector 101 by an elastic force of a torsion spring 332 incorporated in the rotation shaft 33. In addition, a conduction portion 32 a is formed at the tip of the plate 32 of the lock portion 32. The conduction part 32a is formed so that the switches 24a and 24b can be electrically connected when contacting the switches 24a and 24b of the base body 21.

  The rotation shaft 33 is a substantially cylindrical shaft in which the lock portion 32 is disposed on the upper surface portion of the adapter main body 31. The rotation shaft 33 is attached to one surface of the adapter main body 31 (hereinafter referred to as “upper surface”) by a connection body 333 having a substantially Ω shape. A projecting stopper 331 is attached to the rotation shaft 33.

  FIG. 5 is a schematic perspective view showing the internal structure of the rotating shaft 33 in the vicinity of the portion A in FIG. Two torsion springs 332 are incorporated inside the cylinder of the rotation shaft 33, one at each end, and one end of the torsion spring 332 rotates from an opening in which the rotation shaft 33 is formed. It is exposed to the outside of the shaft 33, and the other end is bonded and fixed to the column 321 of the lock portion 32 and to the upper surface of the adapter body 31.

  The torsion spring 332 is caused by its elastic force to move the lock portion 32 in the direction of advancement / retraction of the connector 101 (from the back surface to the connector opening 312, as indicated by the arrow in FIG. Direction)) with an elastic force so as to be tiltable. Therefore, when the lock part 32 is not tilted, as shown in FIG. 5, it is urged | biased in the standing state. Therefore, when the hand is released from the lock portion 32 pushed into the port 201 side, the state shown in FIG.

  Further, the conduction portion 32a and the switches 24a and 24b are electrically connected by pushing and tilting the lock portion 32 toward the port 201.

  As shown in FIG. 7A, the stopper 331 is a component that restricts the movement of the claw portion 102 of the connector 101 so that it cannot be pressed when the connector 101 to which the adapter 3 is attached is connected to the port 201. is there. Further, as shown in FIG. 7B, in a state where the lock portion 32 is tilted toward the port 201, the stopper 331 is similarly tilted, and a gap is generated between the claw portion 102 and the stopper 331, so that the claw portion 102 As a result, the claw portion 102 can be pushed downward.

  The size of the stopper 331 takes into consideration the tilt angle of the lock portion 32 and the diameter of the rotation shaft 33, and the claw portion 102 cannot be pushed down when the lock portion 32 is standing, and the lock portion 32 is tilted. In the state where the conduction portion 32a is in contact with the switches 24a and 24b, the claw portion 102 is set to be pressed. For example, when the diameter of the rotating shaft 33 is small and the lock portion 32 is tilted deeply, the gap between the claw portion 102 and the stopper 331 becomes large, so that the stopper 331 needs to be enlarged.

  The engaging recess 311 is a notch formed at two points at the tip of the adapter main body 31, and is set to a size, shape, and position that engage with the corresponding engaging protrusions 23 a and 23 b of the base 2. Since the engaging recess 311 does not engage with any other than the corresponding engaging protrusions 23a and 23b, when trying to connect the connector 101 to which the adapter 3 is attached to another port 201, the engaging protrusion 23a, Since 23b contacts and interferes with the adapter main body 31, the connector 101 cannot be properly connected to the port 201.

  Next, the usage method and operation of the LAN cable connection device 1 will be described with reference to FIGS.

  First, the base 2 is attached to the surface of the existing IP device 200 on the port 201 side, and the connector 101 of the existing LAN cable 100 is connected to the engagement protrusions 23a and 23b of the base 2 corresponding to the ports 201. An adapter 3 having an engaging recess 311 to be engaged is attached.

  Next, the connector 101 is attached to the adapter main body 31 of the adapter 3. First, the LAN cable 100 is passed through the LAN cable opening 313 from the bottom side, and the connector 101 is housed in the adapter main body 31 from the connector opening 313 (FIG. 8A).

  When the LAN cable 100 is connected to the port 201, the LAN cable 100 to which the adapter 3 corresponding to each port 201 is attached is connected. In this case, the engagement protrusions 23a and 23b corresponding to each port 201 and the engagement recess 311 of the adapter 3 are engaged, so that the connector 101 of the LAN cable 100 is properly fitted to the port 201. They can be connected (FIGS. 8B and 9).

  When removing the LAN cable 100 from the port 201, the conduction portion 32a and the switches 24a and 24b are electrically connected by pushing the lock portion 32 of the adapter 3 toward the port 201 and tilting it (FIG. 7 ( b)), the LED of the display panel 25 provided corresponding to the switches 24a and 24b is turned on, and the number of the port 201 is displayed. Then, the operator confirms the port number of the lit display panel 25 and confirms that it is a removal target. Then, the claw portion 102 of the connector 101 is pressed, and the LAN cable 100 can be removed.

  According to such a LAN cable connection device 1, the base 2 is attached to the surface of the existing IP device 200 on the port 201 side, and the adapter 3 is attached to the connector 101 of the LAN cable 100, so that the lock unit 32 is not pushed in. Since the claw portion 102 of the connector cannot be pressed, it is possible to suppress erroneous disconnection when the LAN cable 100 is pulled out from the port 201.

  Further, when the lock unit 32 is pushed in to pull out the LAN cable 100, the display panel 25 displays the number of the port 201. By confirming this, it is possible to prevent a confirmation error or omission of confirmation. Mistakes can be suppressed.

  Further, when the LAN cable 100 is connected to the port 201, only the LAN cable 100 to which the adapter 3 corresponding to each port 201 is attached is engaged with the engagement protrusions 23a and 23b of the base body 21 and the engagement recesses of the adapter 3. Since 311 is fitted, it can be connected to the port 201. Thereby, the erroneous connection of the LAN cable 100 can be prevented.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, the conduction part 32a electrically connects the switches 24a and 24b to cause the LEDs of the display panel 25 to emit light. However, the switches 24a and 24b are not terminals but push buttons. It may be configured such that the LED of the display panel 25 emits light when the unit 32 is tilted and a button is pressed at the tip. In this case, any one of the switches 24a and 24b is sufficient.

  Furthermore, it is not limited to the combination of the rotating shaft 33 and the torsion spring 332 that the lock portion 32 is kept standing on the adapter body 31. For example, one surface of a leaf spring bent at a right angle is attached to the adapter body 31. The same effect can be obtained by connecting the other surface to the column 321 of the lock portion and utilizing the elastic force of the leaf spring.
