In the power electronic distribution wiring, when the on-screen equipment and the off-screen equipment are connected, they must pass through some special terminal blocks. These terminal blocks are combined and called the terminal block.
The role of the terminal block is to connect the equipment in the screen and the lines of the equipment outside, and play the role of signal (current and voltage) transmission. With the terminal block, the wiring is beautiful and easy to maintain. It is mainly reliable when connecting between long-distance lines, and it is convenient to construct and maintain.
There are many types of terminal blocks. Common types include current terminals, fuse terminals and double-layer terminals. Different types of terminals have different functions.
Current terminal: For the circuit installation process, the circuit needs to be tested, and the circuit must be continuously disconnected and repeatedly operated.
Fuse terminal: For circuit protection in some special cases, the value of an instrument or equipment is inestimable. It is unwise to lose due to the instability of current and voltage, so in this case, you need to have a A device that can protect a circuit.
When the current is too large, the circuit will be automatically disconnected, and the fuse terminal is designed.
Double-layer terminal: For the requirements of space design, it is required to pass more than two cables in a small space, thus designing a double-layer terminal.
Tempered Glass Screen Protector
The JJT Tempered Glass Screen Protective Film is protected by specially treated glass, and the Tempered Glass Screen Protector brings excellent scratch resistance to the screen. The Tempered Glass Protective Film is made of shockproof technology, which has the characteristics of anti-scratch, anti-fingerprint and anti-oil, which can greatly reduce the damage to the screen due to strong collision. The adhesive force of the silicon adhesive ensures that there is nothing between the screen protector and the screen, thereby improving touch sensitivity. Ultra-transparent glass can ensure a better clear image quality than ordinary Screen Protectors.
The surface hardness of the Tempered Glass Screen Protection Film is 9H, which is 4 times that of ordinary PET Film. Sharp objects (such as knives and keys) will not scratch the surface.
The Screen Protector has an "oleophobic and waterproof" coating to prevent fingerprints and other contaminants, making the screen protector easy to clean.
It has unparalleled touch and high responsiveness to touch, 99.9% transparency, transparent without bubbles.
