Junction Box Meets The Requirements Of Outdoor Environment
- Sep 05, 2017 -


With the popularity of broadband in the community, to the user to bring a great degree of convenience, but at the same time encountered other problems, such as community broadband users into the line when the wiring problem, if the wiring is improper, then it may affect the stability of product use, so how to install junction box has become a very important issue.

Junction box with good performance, a series of universal, Junction Box high degree of standardization, high level of protection, beautiful appearance, light weight, low cost, electrical safety measures equipped with a full range of characteristics, can improve the quality of the entire motor products, improve product safety and reliability.

The junction box is one of the electrician's accessories, because the wires in the electric circuit are through the tube or the cable tray, and in the connector parts of the wire (such as the length of the line, or the wire pipe to the corner) to use the junction box for the transition, Junction Box wire and junction box connection, wire tube inside the wiring box connected to Play the role of protecting wires and connecting wires, this is the junction box.

In the home Decoration, junction Box is one of the electrician accessories, because the repair of the wire is through the wire pipe, and in the connector parts of the wire (such as the length of the line, or the wire pipe to the corner) to use junction box as a transition, wire and junction box connection, Junction Box wire tube inside the wiring box connected to the connection, Play the role of protecting wires and connecting wires, this is the junction box.

The general domestic wiring box is 86 type, is roughly in $number millimeter or so, with junction box cover (or directly with switch and socket panel), is generally PVC and tin box material.

The junction box is grouped by a box cover, a box body, a terminal, a diode, a connecting wire and a connector.

function of each part of junction box

The shell should have a strong anti-aging, anti-ultraviolet ability, in line with the outdoor harsh environmental conditions of use requirements;

The Self-Locking function makes the connection way more convenient and firm;

Must have waterproof seal design, scientific protection against electric shock insulation, with better safety performance, wiring terminals should be firmly installed, and converge with good weldability.

Diodes are divided into: bypass diode and anti recoil diode. Junction Box The main function of diode is one-guide-pass function.

Bypass Diode: The main action to prevent the thermal plaque effect of components. Hot spot Effect: When the component is in use, some of the cells are blocked by foreign bodies and will be used as a load to consume the energy generated by other illuminated solar modules. Junction Box The temperature of the shaded solar cell will heat up at this time, which is the hot spot effect. If there is a foreign body to block the battery to cause the local battery chip does not work, the temperature of the local battery is rising, fever will eventually lead to the battery chip burnout.
