There are three specifications of the wiring box: the specification of the interior spiral self-locking terminal is 2.5-3.5 square millimeters, which will introduce a wire fixed connection.Different models of cable sealing sleeve meets different cable introduction: The entrance (installation end) of the plastic cable sealing sleeve is a public thread with anti -pine clamps, which has good mechanical characteristics.
Types of wiring boxes
The first category: traditional type.Structural features: The shell of the back opens with an electrical terminal (slider) in the shell, which connects the various input terminals (distribution holes) of the corresponding ground electrical terminal of the electrical terminal of the solar battery template.The holes on one side of the shell are extended into the shell and connected to the output end holes on the other side of the electrical terminal.Advantages: Clamp connection, fast operation and convenient maintenance.Disadvantages: Due to the existence of electrical terminals, the wiring box is large and poor.The cable holes in the shell will cause the waterproof performance of the product to decrease.Line contact connection, small conductive area, not reliable connection.The second category: seal sealing small type.Advantages: Due to the use of a thin -piece metal terminal tin welding method, the volume is small, and it has better heat dissipation and stability.Because of the sealing of glue, it has better waterproof and dustproof performance.Provide a more flexible connection solution, which can be used in two ways: blocking and non -sealing.Disadvantages: Once problems occur after blocking, it is not convenient for maintenance.
Wiring box price
The price of the wiring box is about 45 yuan.
What is the wiring box
The wiring box, that is, the wiring box is in the home decoration, the wiring box is one of the electrician auxiliary materials, because the wires used in the decoration are passed through the wire tube, and the connection part of the wire (such as the long line, or the corner of the wire tube) adopts it.The wiring box is used for transition, the wire tube is connected to the wiring box, and the wires in the wire tube are connected in the wiring box to protect the wires and connecting wires. This is the wiring box.
