MC4 joint removal pliers for photovoltaic cable

Abstract

The invention discloses a pair of MC4 joint removal pliers for a photovoltaic cable. The MC4 joint removal pliers comprise two parts, namely jaws and plier handles, wherein each jaw comprises five parts, namely a jaw shell, a pressing mechanism, a longitudinal movement mechanism, a transverse guide rail and a separation mechanism; each plier handle is provided with wire stripping openings, range adjusting devices and a PVC handle; two plier handles are connected through a central support pin and a support spring; and the plier handles are connected with the corresponding longitudinal movementmechanisms of the jaws through arc-shaped pull rods. The MC4 joint removal pliers have the beneficial effects that the convenience of MC4 joint removal is strengthened; separation of male and female joints can be achieved through one-time gripping, so that time and labor are saved and the fatigue strength of a joint material can be effectively reduced; and the MC4 joint removal pliers are relatively simple in structure and convenient to use, have a wire stripping function for cables of common sizes, are beneficial to effective application in complicated field environments and are suitable forlarge-scale popularization.

Description

technical field [0001] The invention relates to a dismantling pliers, in particular to a dismantling pliers used for photovoltaic cable MC4 joints, and belongs to the technical field of photovoltaic equipment loading and unloading. Background technique [0002] In recent years, my country's photovoltaic industry has developed rapidly, and its installed capacity has increased significantly. With the passage of time, the photovoltaic industry is bound to gradually enter the post-photovoltaic era in which the main goal is to ensure the stable and efficient operation of power stations, and the daily operation and maintenance of photovoltaic power stations is the main task. The photovoltaic power plants put into operation at this stage are mainly connected by 1kV-1*4mm DC cables on their DC side (including between modules and modules, modules to DC combiner boxes, modules or DC combiner boxes to inverters) , the two ends of the cable are generally connected by MC4 standard conne...

AI Technical Summary

Problems solved by technology

In actual operation, there are the following difficulties: 1. Due to the size limitation of the joint (the width of the buckle groove is about 10mm, and the human finger is generally 15-20mm), when the operator directly presses the buckle of the male joint by hand, it is often difficult to align the groove. 2. When the MC4 connector is in the connected state, even if the buckle is pressed, the static friction between the male connector and the female connector is still very large. It takes a lot of pulling force to directly pull the two connectors with both hands, which is difficult to achieve; 3. The on-site environment of the photovoltaic power station is complex, and the MC4 connector and its connecting cables are usually bundled on the photovoltaic support or located in the narrow gap between the module and the color steel tile roof , the space where the MC4 connector needs to be disassembled is usually small, and it is more difficult to realize the disassembly operation conveniently and quickly

[0006] Most of the existing MC4 connector removal devices on the market are wrench-shaped fixed devices, which require both hands to use. The buckle ejector pin is small, and it is difficult to accurately align the buckle. After pressing the buckle, both hands still need to use force in the opposite direction. It is inconvenient to use by pulling apart the male and female connectors
