Direct insertion type copper-aluminum connector

Abstract

The invention discloses a direct insertion type copper-aluminum connector, which comprises a male end and a female end, and is characterized in that a joint with a copper pipe and an aluminum pipe isarranged in a male end plastic shell; a copper pipe of the connector is inserted into the insertion pipe from the plastic shell, and a buckle is arranged on the edge of the insertion pipe and installed at the end of the plastic shell. A sealing element is arranged at the end part of the other side of the plastic shell, and a plastic ring is arranged outside the sealing element and is provided withextrusion teeth; the plastic cap presses the extrusion teeth to extrude the sealing element, so that the sealing element clings to the aluminum cable; a female end joint with a copper pipe and an aluminum pipe is mounted in the female end mounting cavity; the end part of the female end plastic shell is provided with an insertion hole into which the buckle is inserted; a female end sealing piece is arranged at the end part of the other side of the female end plastic shell, a female end plastic ring is arranged outside the female end sealing piece, and the female end plastic ring is provided with female end extrusion teeth; the female-end plastic cap presses the female-end extrusion teeth to extrude the female-end sealing element, so that the female-end sealing element is tightly attached to the aluminum cable; the device is simple in structure, easy to install, more convenient to maintain and capable of improving reliability and stability.

Description

technical field [0001] The invention relates to an in-line copper-aluminum connector, which can be used instead of MC4. Background technique [0002] The special part of the cable often needs to be isolated from the dust, water, air, etc. of the outside world, such as the connection part of the cable. For example, when the part of the photovoltaic line is changed to an aluminum or aluminum alloy conductor cable, the connection between copper and aluminum is involved. To solve the problem of electrochemical corrosion between copper and aluminum, it is necessary to make a good seal. Otherwise, the connection may fail and affect the safe and stable operation of the photovoltaic line. For a good connection, the contact resistance is slightly higher than the initial value; for a poor connection, the contact resistance may reach tens or even hundreds of times the initial value. The power consumed by one connector is equal to the power consumed by a whole cable. The high contact...
