Problems solved by technology
[0003] The cable will be subjected to a certain tension in the actual use process. In the long-term use process, if the strength of the insulating sheath does not meet the requirements, there will be breakage or cracking, and there will be certain safety hazards. Therefore, the cable The strength test of the wire insulation sheath is an indispensable and important link at the beginning of the lamp design

The invention discloses an insulation testing apparatus of a cable conductor insulation sheath, which comprises a motor, a tensiometer, a connecting piece, a fixed part and a clamping mechanism, the clamping mechanism comprises a first clamping element and a second clamping element used for clamping the insulation sheath, one end of the tensiometer is connected to a rotating shaft of the motor through the connecting piece, the other end is connected to the first clamping element, and the second clamping element is fixed on the fixed part. According to the invention, the first clamping element and the second clamping element are used for clamping the insulation sheath, the rotating shaft of the motor makes the insulation sheath under pulling force by pulling the first clamping element through the tensiometer, the tensiometer displays the pulling force volume of the insulation sheath for testing whether the largest pulling force value of the insulation sheath accords with the practical application requirement or not, and hidden trouble generated by cable conductor fracture due to non-compliance intensity parameter can be avoided.
Description
technical field [0001] The invention relates to the field of lamp production, in particular to a strength test device for cable insulation sheaths. Background technique [0002] As a kind of lighting equipment with high reliability and safety, special lamps are widely used in all walks of life. In the process of using lamps, the carrier of power supply to lamps is cables, so the quality of cables is directly related to the reliability of lamps. Safety and security are guaranteed. The cable mainly includes two parts: the core and the insulating sheath. The core is also the conductor part. Its main function is to provide power to the lamps. [0003] The cable will be subjected to a certain tension in the actual use process. In the long-term use process, if the strength of the insulating sheath does not meet the requirements, there will be breakage or cracking, and there will be certain safety hazards. Therefore, the cable The strength test of the wire insulation sheath is an...
