Wire Harness is the most common internal connection wire inside electrical appliances. Different conductor numbers and spacing can be selected to make the connection between the main board and PCB board more convenient. So how do we judge the specific specifications and models used? Let me teach you a simple judgment method below.
First of all, how to judge the commonly used terminals, such as 1.0mm, 2.0mm, 2.54mm terminal wires? Before judging, we need to understand the meaning of this value. In fact, 1.0mm, 2.0mm, 2.54mm refer to the distance between the adjacent pins of the terminal line. When we get a terminal wire, it is the easiest to judge the specific specifications of the terminal. The method of model is to first measure the distance between the adjacent pins of the terminal. According to the distance between the adjacent pins of the terminal, we can roughly know the terminal model used by the wiring harness.
Secondly, in addition to measuring the distance between the adjacent pins of the terminal, we also need to judge that the terminal joints are equipped with or without needles. The needles are divided into straight needles (the needle and the rubber shell are in a 180° direction) and the horizontal needle ( The needle and the rubber shell are in the direction of 90°), the real pins with a spacing of 2.0mm and 2.5mm are SAN and SCN terminal lines, while the horizontal pin terminals with a spacing of 2.0mm and 2.5mm are JC20 and JC25 terminals respectively.
In addition, for some cold-pressed torus terminals, you need to measure the diameter of the inner circle, the diameter of the outer circle, and the thickness of the ring, and you can know some specific parameters of the cold-pressed torus, so as to find out which type of cold Press the terminal of the ring.
Finally, in the face of some special terminals, such as Molex, JST, Hirose brand terminal housings, we need to measure the length and width of the pin spacing. Customers can also provide pictures or design drawings to professional manufacturers. They have many years of experience in the industry. They are often able to know the specifications and models of the terminal wires in the face of some special terminal rubber shells!
