However, the outer sheath and other protective layers of the wires at the cable connection are stripped in advance. Therefore, the lack of the armor protecting the wires at the cable connection not only has low mechanical strength but is also easily gnawed by rats and insects. In view of this, this article proposes a cable with reinforced insulating glue at the cable head. Content of the Utility Model

[0009] Preferably, a heat shrinkable tube is connected between the multiple small openings at one end of the heat shrinkable finger sleeve and the several three-way pressure connectors. The inner wall of the heat shrinkable tube is fittingly installed around the insulating layer.

[0010] Preferably, a plurality of fixing plates are fixedly installed at the connection of the opening edges of the two protective insulating half-shells. A strip-shaped groove is arranged in the fixing plate. A bolt is connected between the two fixing plates that are symmetric left and right in the two protective insulating half-shells, and the bolt passes through the strip-shaped groove.

[0011] Preferably, three semi-lip seal tubes are communicated with the peripheries of the two protective insulating half-shells, and the peripheries of the three outer sheaths are respectively hermetically clamped and installed between the six semi-lip seal tubes in the two protective insulating half-shells.
