Judging whether a switch socket is good or bad, the material is very important, especially the shrapnel material inside the switch socket. A friend who has bought a switch socket will find that the mainstream of the market is tin phosphor bronze and pure copper. So, which of the two shrapnel materials is better?

First, the performance requirements of the socket shrapnel


The socket shrapnel mainly plays the role of clamping the plug and achieving electrical conduction. This requires the elastic piece to have excellent electrical conductivity first. The second is to have good elasticity and flexibility. The strength of the elastic piece and the plug is not too small. It can clamp the plug and can be easily pulled out. The resilience of the shrapnel is better. After repeated insertion and removal, the elasticity and rebound resilience should be within the control range. The national standard can be repeatedly inserted and removed 40,000 times. At the same time, the shrapnel will not rust, anti-oxidation and anti-arcing, otherwise it will lead to a decrease in electrical conductivity.



Second, the performance of pure copper shrapnel and tin phosphor bronze shrapnel


Before the advent of composite materials, pure copper is indeed the best conductive material, and the performance of copper materials is also high. The purity of copper, the purer copper, the better the conductivity. Brass is better, copper is better than brass, but copper has its inherent defects, one is softer, the second is low toughness, the resilience is not particularly good, and the other is easy to oxidize and rust. Of course, this is compared with the more popular tin-phosphor bronze. The performance of tin-phosphorus bronze is better than that of pure copper. Especially, the oxidation resistance is significantly improved, and the hardness and toughness are obviously improved. The shrapnel made of phosphor bronze can easily reach more than 50,000 times, and some performances can be doubled. For example, the Tanjung switch socket introduced in the above, the number of repeated plugging and unplugging is more than 80,000 times, so some It is not surprising that the switch socket brand can scream for a 20-year warranty and a lifetime warranty.



The above is the introduction of the switch socket shrapnel material pure copper material and tin phosphor bronze material. When buying switch sockets, everyone should pay attention not only to the appearance, appearance materials, shrapnel materials but also to the thickness and workmanship of the shrapnel. Performance and life to the switch socket.
