Embodiment Construction

[0022] like Figure 1-3 As shown, the insulating waterproof head includes a cable 1, a first adhesive heat shrinkable tube 3, and a second adhesive heat shrinkable tube 4. The two ends of the heat-shrinkable tube with glue 3 are put on the two wires respectively, the second heat-shrinkable tube with glue 4 is put on the cable at one end, and the other end of the heat-shrinkable tube with glue is crimped with pressure clamps, and the crimping length is 10mm-30mm, the diameter of the first heat-shrinkable tube 3 with glue is d=4mm, and the diameter of the second heat-shrinkable tube 4 with glue is d=10mm.

[0023] The production method is as follows: the end of the cable 1 with the insulated waterproof head is stripped off the two flexible wires 2 at the remaining free end of the end sheath; The difference in cutting length is 5 mm to 10 mm; put the two ends of the first glued heat-shrinkable tube 3 (d=4mm) into the two wires 2, and use a heat gun to heat seal the first glued h...

Abstract

The invention relates to an insulation waterproof joint and a manufacture method thereof. The insulation waterproof joint comprises a cable, a first rubber heat shrinkable tube and a second rubber heat shrinkable tube. The invention is characterized in that two strands of conducting wires of the cable comprise a short one and a long one, both ends of the first rubber heat shrinkable tube are respectively sheathed on the two strands of conducting wires, one end of the second rubber heat shrinkable tube is sheathed on the cable, and the other end of the second rubber heat shrinkable tube is pressed and connected through a pressure tong. The invention is widely used for the insulation waterproof treatment on the cable ends in household electrical appliances, constructional engineering and port engineering. The invention has the advantages of avoidance of the occurrence of short circuit phenomenon, good electric insulation performance, good ageing resistance performance, high durability, fast construction speed, good safety performance and wide application.

Description

technical field [0001] The invention relates to a waterproof joint and a manufacturing method thereof, in particular to a double heat-sealed waterproof joint using a heat-shrinkable tube with glue and a manufacturing method thereof. Background technique [0002] The current joint treatment method is to wrap multiple layers of insulating waterproof tape, which has poor waterproof performance and poor aging resistance, especially when the temperature is above 40°C, the durability is poor. Contents of the invention [0003] In order to overcome the defects of the prior art, the object of the present invention is to provide an insulating waterproof head and its manufacturing method, which is widely used in the insulation and waterproof treatment of cable ends in household appliances, construction projects, and port projects. [0004] The present invention adopts following technical scheme: [0005] An insulating and waterproof sealing head, including a cable, a first glued he...
