Description

  The present invention relates to a connector repair unit that enables a connector to be used without cutting a cable when a claw-shaped fixing member is dropped from a connector installed at an end of the cable.

  As shown in FIG. 15A, a modular cable or a fiber channel cable, which is a telephone or LAN (Local Area Network) cable, has a claw-shaped fixing member in the connector portion. It is connected and fixed using this nail-shaped part.

  The fixing member has a thin claw shape and extends so as to protrude from the connector. Therefore, if an external force in a direction other than the connector main body is applied to this part, it is easily damaged as shown in FIG. The breakage of the fixing member is likely to occur when the cable is installed or when the connection destination is changed.

  When the fixing member is damaged, it is easy to replace the entire cable, such as a telephone modular cable or a short LAN cable. However, it is not easy to replace the entire long LAN cable or the cable laid under the floor.

  In addition, if the LAN cable can be purchased at low cost, the cost of replacing the entire cable will not increase, but LAN cables with large categories and LANs with STP (Shielded Twisted Pair cable) instead of UTP (Unshielded Twisted Pair cable) Cables and fiber channel cables are expensive, and replacement requires high costs. For this reason, such expensive cables may be difficult to replace for economic reasons, even though they can be physically easily replaced.

  It is conceivable to replace the damaged connector for repair, but in this case, there are the following problems.

The first problem is that it is not easy to replace and repair the connector.
In the case of a modular connector for a LAN cable, a replacement connector and a tool for crimping the connector to the cable are relatively easily available. However, the work of crimping the replacement connector to the cable requires a certain level of skill, and if performed by an unskilled person, there is a possibility that the fixing strength is insufficient or a connection failure may occur.
In the case of a fiber channel cable, the cable needs to be repaired by fusion, and a dedicated optical fiber fusion device is required. Furthermore, repair by fusion requires advanced techniques. Therefore, it is not easy for a skilled person to replace and repair the connector.

  The second problem is that even if the connector can be replaced and repaired, the cable quality equivalent to that before the connector replacement cannot be guaranteed. For example, the quality of the signal attenuation characteristics is guaranteed at the time of cable manufacture, but the cable quality after repair is different from that at the time of manufacture because it is necessary to cut the cable when replacing the connector. In order to guarantee the cable quality, it is necessary to check the cable quality using a dedicated device after replacing the connector.

  As a technique related to the repair of the connector, there is a “repair modular plug cover” disclosed in Patent Document 1 and a “modular jack claw break repair attachment” disclosed in Patent Document 2.
