This section provides an overview for board terminal blocks as well as their applications and principles. Also, please take a look at the list of 34 board terminal block manufacturers and their company rankings. Here are the top-ranked board terminal block companies as of December, 2023: 1.Xiamen Hongfa Electroacoustic Co.,Ltd., 2.Omron.
A board terminal block is a component designed to be installed on a printed circuit board and electrically connected to other boards or components via wires or cables.
There are various ways to connect board terminal block to wires and cables.
As an example, there are types that fasten wires with screws via crimp terminals, etc., attached to the end of wires. There are also types that have a spring built into each terminal of the board terminal block and tighten and fasten wires by inserting wires while pressing down on the designated locations on each terminal.
In either type, soldering to connect wires or cables to the board terminal block is no longer necessary, so even those without soldering skills can use them.
Board terminal blocks are used to connect multiple PCBs or PCBs and components, and this explains, for example, the benefits of separating boards or components for each functional unit.
For example, a circuit design is divided into three types of boards, A, B, and C. In this case, the A board is used to realize basic functions, the B board is used for additional functions, and the C board is used for additional functions .
As a result, different products can be created by simply changing the combination of boards, such as a product with only board A, a product with board A and board B, a product with board A and board C, or a product with all boards A, B, and C.
The above advantages can be achieved by using board terminal blocks to separate board designs.
Depending on the uses of the board terminal blocks, it is necessary to consider the material, insulation resistance, operating temperature range, applicable PCB thickness, and compliance with various laws and regulations.
In order to sell various products and components, including PCB terminal blocks, in Japan, it is necessary to design products in accordance with domestic laws and regulations, but when exporting products and components to Europe, it is essential to comply with the ROHS directive (restriction of hazardous substances). In the case of exporting products and components to Europe, compliance with the ROHS directive is mandatory.
Particular attention must be paid to various components, including PCB terminal blocks.
The ROHS directive requires that the concentration of certain hazardous chemical substances in electrical and electronic equipment be kept below a certain level and that the equipment be lead solder-free (solder that does not contain lead components must be used).
The specific chemical substances are lead, mercury, hexavalent chromium, cadmium, polybrominated biphenyls, polybrominated diphenyl ethers, di-2-ethylhexyl phthalate, butyl benzyl phthalate, di-n-butyl phthalate, diisobutyl phthalate, and the above 10 substances, each of which must contain 0.1% or less of the following The ROHS directive requires that the content of each of these substances be 0.1% or less.
This is because the ROHS directive aims to facilitate the recycling of electronic equipment and to prevent these hazardous substances from adversely affecting the human body at the time of disposal of electronic equipment.
