Description

Technical Field

[0001] The utility model belongs to the technical field of rubber insulation testing, and in particular relates to an insulation testing device for a cold shrink tube. Background Art

[0002] Cold shrink tubing generally refers to cold-shrink cable accessories. These are injection-vulcanized and factory-molded elastomeric materials (commonly silicone rubber and EPDM), then expanded and lined with plastic spiral supports. During on-site installation, these pre-expanded components are placed over the treated cable ends or connectors. The internal plastic spiral strips (supports) are then removed and pressed against the cable insulation to form the cable accessory. Because cold shrink tubing shrinks at room temperature using elastic force, rather than heat-shrinkable cable accessories that require heating, it is commonly known as a cold-shrink cable accessory. After manufacturing, the tubing's various performance characteristics must be tested.

[0003] Chinese patent CN213364945U discloses an insulating rubber withstand voltage detection device, which relates to the field of voltage detection technology. An insulating rubber withstand voltage test includes a detection box, a partition is fixedly connected between the inner top wall and the inner bottom wall of the detection box, an AC motor is provided on the inner bottom wall of the detection box, the left side of the AC motor is electrically connected to a power cord, the end of the power cord away from the AC motor extends to the left side of the detection box and is fixedly connected to a plug, the output end of the AC motor is electrically connected to a transformer through a wire, a contact relay is fixedly connected to the right side of the partition, and the transformer is electrically connected to the contact relay through a wire, two electric push rods are fixedly connected to the inner top wall of the detection box, the output ends of the two electric push rods are fixedly connected to a metal plate, the upper surface of the metal plate is provided with a detection positive electrode, and the left side of the metal plate is fixedly connected to a contact block.

[0004] Existing detection devices are generally manually operated, which poses certain safety hazards, is inefficient, and has poor accuracy. In the above document, by setting up positive and negative detection electrodes, it is convenient to perform voltage breakdown and voltage resistance tests on insulating rubber plates. However, the copper plate used to prevent the object to be detected is located inside the detection box. When taking it, you need to reach into the detection box, and it is flat, which makes it difficult to fix the cylindrical cold shrink tube, making it inconvenient to use.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
