The high current cold pressed terminal series combines easy to operate plug-in connections with sturdy and universal screw methods, connecting various parts together
The high current cold pressed terminal is composed of two parts that are plugged and connected. One part compresses the wire and then plugs it into the other part, which is soldered onto the PCB board
This bottom mechanical principle and anti vibration design ensure the long-term airtight connection of the product and the reliability of the finished product
Both ends of the socket can be equipped with matching ears, which can greatly protect the contacts and prevent poor arrangement of the contacts. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body
High current cold pressed terminals are used to achieve electrical connections and are used for wiring, with no strict difference from terminal posts. However, UL quick plug terminals are usually used in distribution boxes for convenient wiring and generally have a lower power capacity
Various problems often occur during the use of cold pressed terminals. If the cold pressed terminal turns black, one possibility is not necessarily burning black, oxidation may also cause black. So how do we verify if it's burnt black
The method we adopt is to wipe with our fingers. If it can be wiped off, like cigarette ash, it is a black substance formed by oxidation, which can only be removed with sandpaper or file. The terminal expert of Longyi Terminal reminds you that one thing to pay attention to here is: do not wipe with your fingers when charged! So another possibility is that it has been burned black. Apart from the fire and the qigong master's work, there is only one possibility, which is that the wiring terminals are overheated and hot. There are two possible causes of high temperature: loose terminals leading to excessive contact resistance and overheating; The terminal is not loose, but the circuit is overheating due to some unknown reason, such as high power supply voltage or short circuit of the load
1. The voltage is too high. You can start from the source by checking the secondary voltage of the transformer, the voltage inside the distribution box, and the voltage of each electrical equipment. The socket can also have assembly buckles and locking buckles. The assembly buckle can provide a more stable fixation to the PCB board, The locking buckle can lock the mother body and socket after installation is completed. Various socket designs can be paired with different insertion methods for different substrates, such as horizontal, vertical, or tilted towards the printed circuit board
You can choose either metric line gauges or standard line gauges
2. Grounding fault. You can also start from the transformer and then go to the distribution box for grounding. The one that should be grounded should be grounded, while the normal phase line should eliminate grounding faults
When the power is cut off, an insulation meter or a shaking meter can be used for measurement. The measurement should be carried out in sections, and only cables, wires, circuit breakers, switches, and other power supply and distribution lines should be measured in sections as much as possible. If it is difficult to measure in sections, the fuses of weak current equipment and sensing equipment should be removed
The key to grounding is to have a low grounding resistance and a large contact area. The former can ensure that the grounding point has a "zero potential" as low as possible, close to the ground potential
This can avoid the possibility of lightning "reversing" from the grounding wire and entering the power supply circuit after lightning strikes. The latter can ensure sufficient capacity to provide a fault current channel
Including lightning or short circuit faults, etc. Because the actual construction process has always been subject to changes in contemporary technology and science, the feasibility and effectiveness of this grounding method depend on how the new standard specifications are defined
