Copper in household sockets is a key component to ensure smooth current and reduce heat. Excellent quality household sockets are the use of high-quality copper parts, antioxidant, toughness, copper sheet thickness, less riveting, is the socket copper high-quality or not the four major indicators.
A, copper sheet thickness, improve the current through capacity, reduce the resistance of the copper itself;
B, anti-oxidation, not rust, reduce the resistance caused by rust and heat problems;
C, less riveting, it is best to the whole piece of copper, further reduce the riveting part of the break and rivet heating situation.
D, strong toughness, especially used in the socket socket socket part, not easy to deform. Even if the socket is used for a long time, it can maintain a suitable clamping force, ensuring that the socket is tightly connected to the plug and reducing the arc;
A few years ago, the socket with brass as a carrier is the mainstream; Brass appearance is bright yellow, good conductive capacity, soft texture, wear-resistant but antioxidant, toughness (elastic) performance is not ideal. After long-term use of brass, the surface of copper will be oxidized rust, color darkened, will increase the contact resistance, after repeated unplugging, brass plate due to poor toughness, serious deformation, often appear unable to access electricity phenomenon, or due to poor contact to form an arc, can not guarantee safe electricity.
At present, mainstream sockets use tin phosphor bronze as a copper material. Tin phosphor bronze alloy appearance is fuchsia, the biggest feature is its high fatigue strength, strong elasticity, corrosion resistance, excellent antioxidant performance. Even after long-term use, its surface will not be oxidized and corroded, the sleeve will not be deformed, always maintain a suitable clamping force.
Consider the thickness of the copper piece, such as can not open the product visual inspection, can use a simple hand weight method. The more copper is used, the heavier the socket.
Large brand socket products, is basically using tin phosphor bronze to do load-carrying parts, so as to ensure the normal service life of sockets more than 12 years. Such as strong east spring hardware socket copper sheet, the use of integrated socket copper sheet, the use of continuous mold process, the selection of high-quality tin phosphorus copper high-precision belt a processing molding, to avoid excessive riveting point, reduce the resistance of the material itself, reduce the riveting part of the break and rivet heating situation, fundamentally eliminate the riveting point affecting the quality of the after-effects, the safety performance of the socket greatly improved.
It is understood that the hardware factory socket shrapnel selected tin phosphorus bronze material, not only has a good conductive properties of copper, but also good elasticity, anti-fatigue, corrosion resistance, antioxidant performance is very superior. In order to make the plug-in performance more perfect, Sanxiong Aurora socket copper piece thickness of more than 0.6 mm, to ensure that the series of socket clamping force is stronger, more smooth pull, pull more than 15000 times after the normal use, far higher than 5000 times the national standard.
