The characteristics, types, applications and development of rivets
Riveting a nail-shaped object with a cap on one end: in riveting, a riveted part connected by its own deformation or interference.There are many kinds of rivets and they are informal in form. Types and applications of rivets: Commonly used are R type rivet, fan rivet, blind rivet, tree rivet, hal...Read more -
The determination of rivet diameter, length and aperture
When rivet, if rivet diameter is too large, upsetting forming is more difficult, easy to make sheet metal deformation.On the contrary, if the diameter of the rivet is too small, the strength of the rivet is insufficient, resulting in the increase of the number of rivets and the inconvenience of c...Read more -
Composite silver contact details
Composite silver contacts broadly refer to the electrical and electronic electrical electrical opening and closing, the intersection of separation and touch, because the metal conductor terminalinthery in the moment of touch simply produces instant heat and sparks, prompting its touch point in th...Read more -
Silver Alloy Performance Improvement
Silver alloy performance improvement Silver is extremely soft and easy to process. In order to improve its strength and hardness and increase its wear resistance, people have long added copper to silver to make silver-copper alloys, which are used in jewelry, tableware and silver coins. In order ...Read more -

The working performance of silver contact can be improved af
In order to avoid the sake of silver contact burning, static contact terminal into a curved shape, intermediate contact protruding part. So the arc will not on the contact surface of the combustion. It is a kind of better contact form, and its application is increasingly extensive. The working pr...Read more -
Energy is concentrated in the contact surface and in the nea
Arc discharge process, arc root produces the thermal physical process due to concentrated energy release in the contact surface and near surface layer, caused by melting and evaporation of silver contact materials, this is silver contact electric ablation. In the breaking current small and short ...Read more -
Relay contact protection and contact matters
We know that the contact relay should be more cruel than the general Mosfet, the relay load is much larger than Mosfet. Common DC load DC motor, DC clutch and DC solenoid valves, these perceptual load switch is closed, hundreds or even thousands of volts of back electromotive force caused by the ...Read more
