Cable connector

Abstract

The invention discloses a cable connector, which comprises a male pole plug and a female pole plug, wherein the connecting end of the male pole plug is matched with the connecting end of the female pole plug; copper pole tubes are respectively arranged in the male pole plug and the female pole plug, and the tail parts of the copper pole tubes are connected with gripper tubes; the tail parts of the male pole plug and the female pole plug are respectively connected with nuts, and the nuts are connected with the gripper tubes by sealing rings; the connecting end of the male pole plug is provided with a positioning post, and the two sides of the positioning post are provided with elastic plug pins; the connecting end of the female pole plug is provided with jacks matched with the elastic plug pins; and each of the bottoms of the jacks are provided with a sliding chute, and a locking plate is movably arranged in each sliding chute. According to the cable connector, the sealing rings are in cone shape, so as to effectively lock a cable and prevent water from entering from the gaps between the nuts and the cable. A backstop groove and a backstop lug that are matched with each other are arranged at the screwing position, so as to avoid the accident of accidental loosening. The cable connector is ingenious in structure, convenient in connection and higher in safety.

Description

technical field [0001] The invention relates to an accessory of a cable, in particular to a cable connector. Background technique [0002] Connectors are an important part of photovoltaic modules. The usage is large and wide. At present, almost all manufacturers imitate the connectors of MC Company. In actual use, there are the following risks: [0003] 1. The inner wall of the male and female pole socket plastic parts will shrink due to craftsmanship and man-made reasons. Make it impossible to cooperate with the retaining ring. With a pulling force of tens of cattle, the male and female pole plugs, intubation tubes and wires will slide out (the pull-out force is required to reach >350N), which will cause safety accidents; [0004] 2. There is a 0.5mm interference gap that cannot be crossed during the mating process of the male and female plugs, cannula and stop ring. It will cause increased contact resistance, unstable current, increased temperature rise, and reduc...

AI Technical Summary

Problems solved by technology

[0003] 1. The inner wall of the male and female pole socket plastic parts will shrink due to craftsmanship and man-made reasons.

Make it impossible to cooperate with the retaining ring

With a pulling force of tens of cattle, the male and female pole plugs, intubation tubes and wires will slide out (the pull-out force is required to reach >350N), which will cause safety accidents;

[0004] 2. Due to the 0.5mm interference gap that cannot be crossed during the mating process of the male and female pole plugs, cannula and stop ring

It will cause increased contact resistance, unstable current, increased temperature rise, and reduced service life;

[0005] 3. After the nut and the connector are locked, creep will occur over time and will affect its safety;

[0006] Most of the connectors currently used have no safety devices, which are easy to cause artificial (children) disconnection, resulting in unnecessary losses
