Description

  The present invention attaches to the end of a cable so that a plurality of core wires are arranged in a horizontal direction and terminates, a contact exposed side on the side where a plurality of connector contacts are arranged in a horizontal direction, and a side opposite to the contact exposed side Connecting and removing a modular plug (eg, RJ45 plug) having a latched side with a latch spring piece from a modular jack (eg, RJ45 jack) in a connector interface of a server, IP phone, Ethernet, etc. The present invention relates to a modular plug insertion / extraction tool for performing the above.

  Conventionally, when removing a modular plug from a modular jack in a connector interface such as a server, IP phone, Ethernet, etc. where many cables are crowded, the latch is released with the tip of a bamboo spatula held in one hand or a plastic sorting bar. While pulling down the latch piece, pull the cable with the other hand and pull it out.

On the other hand, in the case of an optical cable that is not a metal cable, generally, when the optical connector is coupled, the connector connection state is maintained by the self-holding mechanism built in the MU-type plug-in optical fiber connector by the ferrule inside the plug, and the RJ45 plug connector As shown in Patent Document 1 or Patent Document 2, the connector insertion / extraction tool is an end that complementarily engages with the irregularities formed on the side surface of the plug connector. There are tongs with parts.

  Conventionally, the removal work using the bamboo spatula or the arranging bar for the RJ45 plug at the connector interface in which the jacks are densely packed together requires using both hands, and the workability is poor, and the connector used for the optical connector The insertion / extraction tool cannot release the latch of the RJ45 plug and cannot be used.

  Accordingly, an object of the present invention is to obtain a modular plug insertion / extraction tool that can easily insert / extract an RJ45 plug or the like by one-hand operation in a connector interface group in which a large number of cables are dense and it is difficult to insert a hand.

  In order to achieve this object, the modular plug insertion / extraction tool of the present invention has flat jaw members made of plastic at the tip of each leg of the tweezers-like body, and these jaw members have clamping surfaces facing each other, The clamping surface of the jaw member is a flat surface that engages the latch spring piece of the modular plug, and the clamping surface of the other jaw member is provided on the contact exposed side of the modular plug or on the base end side of this contact exposed side It is characterized by having a projection surface having a projection that engages with the recess.

  In general, in the case of a module plug such as a hard plastic RJ45 plug, a portion from the core wire exposed at the cable end portion to the front end portion of the outer sheath of the cable is inserted and stored in the case of the RJ45 plug. Next, the RJ45 plug containing the cable end is set in the plug receiving portion of the pliers-shaped cable pressure welding tool. Finally, by gripping and squeezing a pair of handles of the cable pressure welding tool, the connector contact group provided on the RJ45 plug is bitten into the core wire at the same time, and a part of the plug case is crimped into the cable sheath. .

  In this way, the RJ45 plug can be firmly fixed to the cable end portion and terminated. At this time, it is general that a depression is generated in the caulking portion on the base end side on the contact exposed side surface of the plug case.

  In some cases, a plug boot that covers from the base end portion of the case to the front end portion of the cable may be attached so as to close the cable insertion side opening of the plug case. In this case, the depression of the caulking portion is covered with the plug boot.

  According to the modular plug insertion / extraction tool of the present invention, the flat clamp surface of the jaw member at the tip of the leg is applied to one side of the tweezer-shaped body to the latch spring piece, and the protrusion of the surface with the protrusion of the jaw member at the tip of the other leg Is engaged with the side of the plug boot on the side where the contact is exposed or the recess provided on the base end side of the side where the contact is exposed, and the tweezers body is pinched and the plug case is clamped to push down the latch spring piece. The latch can be released and pulled out from the modular jack.

  Since the jaw member is flat, this drawing operation can be easily performed even in a connector interface where cables are densely packed. Moreover, it can be used not only for the drawing work but also for the connector connection work at a cable dense place where the hand cannot enter.

  In a preferred embodiment of the modular plug insertion / extraction tool of the present invention, the tweezer-shaped main body and the jaw member are configured as separate members, and the insertion hole is provided in the axial direction from the rear end surface of the jaw member toward the front. Insert the tip of the flat leg of the tweezers-like body, screw the set screw into a pair of lateral holes provided in the lateral direction so as to communicate with the insertion holes from the lateral sides on both sides of the jaw member, and attach the tip of the screw to the flat leg. The flat jaw member is detachably connected to the tweezer-like body by biting into a notch provided on the lateral side surface of the distal end portion of the tweezers. According to this configuration, when the jaw member is worn or damaged, it can be replaced with a new jaw member.

  In another preferred embodiment of the present invention, the tweezer-shaped body is made of metal, and the jaw member is made of plastic. In this case, it is preferable that the metal tweezer-shaped main body is covered with an insulator, for example, a hishi tube. In still another preferred embodiment, the tweezer-shaped main body and the jaw member are integrally formed of plastic.

Furthermore, in a preferred embodiment of the modular plug insertion / extraction tool of the present invention, at least the top surface of the protrusion is processed to be a surface having a high coefficient of friction with respect to the boot that closes the cable insertion opening of the modular plug, or a pair of projections. These jaw members are made of a plastic having a high coefficient of friction. According to this structure, even if it is a modular plug with a boot which covers the hollow provided in the base end side of a contact exposed side surface, it can hold | grip firmly.
