Problems solved by technology

[0003] On the other hand, the process involved in the production process of the cable joint is complicated, and the crimping of the cable conductor part is the most important process in the entire cable joint production process, and the crimping of the cable is mainly done manually with the help of simple tools.
Therefore, due to the difference in the technical level of the staff and the difference in crimping tools, etc., the crimping joint may not be tight and the contact resistance is too large. Long-term operation will cause the cable joint to overheat, thereby burning through the insulation and other problems, resulting in interruption of line power supply

Abstract

The invention discloses a cable crimping performance test platform and a cable crimping performance test method, wherein the cable crimping performance test platform comprises a crimping mold fixing device, a cable fixing device, a cable moving device, a contact resistance test device, a pressure measurement device and a displacement measurement device, wherein the crimping mold fixing device is used for fixing a crimping mold for crimping a cable; the cable fixing device is used for fixing a to-be-crimped cable; the cable moving device is connected with the cable fixing device; the contact resistance test device is used for measuring contact resistance between the to-be-crimped cable and a connection tube; the pressure measurement device is used for measuring pressure generated by the crimping mold when crimping the to-be-crimped cable; and the displacement measurement device is used for measuring displacement of the connection tube generated after deforming under pressure.

Description

technical field [0001] The invention relates to the technical field of crimping of conductor parts of cable joints, in particular to a cable crimping performance testing platform and a testing method thereof. Background technique [0002] The year-by-year increase in the cable conversion rate has brought about a rapid increase in the amount of cable construction. Among them, the production of cable joints is the most important link in cable construction. The process involved in the manufacturing process of the cable joint is complicated, and the crimping of the cable conductor part is the most important process in the entire process of making the cable joint. The quality of the cable crimping process directly affects whether the cable laying work is qualified or not. At present, how to improve work efficiency and reduce work cost while ensuring crimping quality is the main consideration. From the point of view of improving the working efficiency of cable crimping, there a...
