Description

  The present invention relates to a LAN connector having a locking lever having a claw breaking preventing function, the LAN connector being used when the locking lever is attached to or detached from a LAN connector fitted to a fitting portion provided in a tubular member. It relates to a detachable jig.

  The LAN connector having the locking lever can be easily removed from the housing by the operator pressing the locking lever with his / her finger. However, when the fitting portion to which the locking lever is fitted is provided in, for example, the waterproof bush, when the LAN connector is attached to the housing, the locking lever is inserted into the waterproof bush. It is difficult to push the locking lever with fingers.

On the other hand, a method of operating a locking lever using a jig has been conventionally known (for example, see Patent Document 1). The method disclosed in Patent Literature 1 is intended for attaching and detaching an optical connector having a locking lever similar to a LAN connector. In this optical connector, due to security problems, the locking lever is protected by a security cover so that the locking lever cannot be easily operated with fingers. Therefore, a jig for removing the security cover from the locking lever is prepared, and the operator removes the security cover by pressing the locking lever using the jig.
By applying this method to the LAN connector, the locking lever can be easily operated even when the fitting portion is provided in the waterproof bush.

Next, an example of the attaching / detaching operation of the LAN connector 1 using the LAN connector attaching / detaching jig 4a according to the first embodiment of the present invention will be described with reference to FIGS.
First, a case where the LAN connector 1 is detached from the housing 21 will be described.
When detaching the LAN connector 1 from the housing 21 located at the back of the waterproof bush 22, first, the worker places the LAN connector attaching / detaching jig 4 a near the waterproof bush 22 on the LAN cable 3 as shown in FIGS. Put. Then, the operator adjusts the direction of the LAN connector attaching / detaching jig 4a so that the mark 44a is aligned with the mark 24. Then, the worker inserts the LAN connector attaching / detaching jig 4a into the waterproof bush 22 along a line connecting the marks 44a to 46a in a straight line. Thereby, the LAN connector attachment / detachment jig 4a can be inserted by aligning the lever receiving portion 42a with the direction of the locking lever 11 located in the waterproof bush 22.

  Then, as shown in FIG. 6B, the operator inserts the LAN connector attaching / detaching jig 4a into the waterproof bush 22 up to the position of the mark 45a. Thereby, the lever receiving portion 42a can be inserted up to the position of the locking lever 11 located in the waterproof bush 22. As a result, the lever receiving portion 42a pushes down the locking lever 11 from the fitting portion 23, and releases the fitting (lock) between the locking lever 11 and the fitting portion 23.

  Thereafter, as shown in FIG. 6C, the operator grasps the LAN connector attaching / detaching jig 4a together with the LAN cable 3 and pulls out the waterproof bush 22. Thus, the LAN connector 1 can be removed from the housing 21.

Next, a case where the LAN connector 1 is attached to the housing 21 will be described.
Here, as shown in FIG. 7, when the lever receiving portion 42 a is put on the locking lever 11 and is to be inserted into the waterproof bush 22, the lever receiving portion 42 a is in a state of pushing the locking lever 11. The LAN connector 1 is pushed down in the direction of the arrow shown in FIG. 7 by the reaction force of the stop lever 11. Therefore, mounting on the housing 21 becomes difficult.

  Therefore, when attaching the LAN connector 1 to the housing 21, first, as shown in FIG. 8, an operator places on the connector support portion 43 a a surface (bottom surface) opposite to the locking lever 11 of the LAN connector 1. ). In the example of FIG. 8, the LAN connector 1 can be positioned by bringing the rear surface of the LAN connector 1 into contact with the side surface of the connector support portion 43a. Then, as shown in FIG. 9, the operator adjusts the orientation of the LAN connector 1 so that the locking lever 11 is aligned with the mark 24. Then, the operator grasps the LAN connector attaching / detaching jig 4a together with the LAN cable 3 and inserts it straight into the waterproof bush 22 to the position of the mark 45a. Thus, the LAN connector 1 can be attached to the housing 21. At this time, since no reaction force is generated by the locking lever 11, the LAN connector 1 is not pushed down, and the LAN connector 1 can be easily attached to the housing 21.

Thereafter, the worker pulls out only the LAN connector attaching / detaching jig 4a from the waterproof bush 22.
Here, if the LAN connector 1 is attached to the housing 21 without using the LAN connector attaching / detaching jig 4a, the LAN cable 3 is bent when the LAN connector 1 is inserted into the waterproof bush 22, and is difficult to attach. Becomes On the other hand, by using the LAN connector attaching / detaching jig 4a, the LAN cable 3 can be inserted while being supported straight by the LAN connector attaching / detaching jig 4a, and the LAN connector 1 can be easily attached to the housing 21.

  As described above, according to the first embodiment, the main body 41a made of a material harder than the locking lever 11 and the one end on the back surface of the main body 41a, A lever receiving portion 42a that can be positioned between the lever 11 and the fitting portion 23, a first mark (marks 44a to 46a) provided on the surface of the main body portion 41a and indicating a location of the lever receiving portion 42a, A second mark (mark 45a) which is provided on the surface and indicates the depth of insertion of the main body 41a into the waterproof bush 22 when the lever receiving portion 42a is located between the locking lever 11 and the fitting portion 23; Therefore, the direction and depth of inserting the LAN connector attaching / detaching jig 4a into the waterproof bush 22 can be grasped.
