Abstract
The invention discloses an elastic contact which is formed by jack assemblies and contact pin assemblies. The contact pin assemblies are rigid pieces formed in a punched mode. The middles of the contact pin assemblies are of square structures. A locating boss (1) is arranged on each square structure. A tail contact pin (2) is connected to one end of each square structure. An insertion contact pin (3) is connected to the other end of each square structure. The jack assemblies are elastic pieces which are made of copper alloy band materials and formed in a punched mode. A forced-pressing fixing hole (4) which is formed in a punched mode and has the elasticity is formed in the tail of each jack assembly. The forced-pressing fixing holes (4) are used for being fixedly installed with printed boards in a forced pressing mode. The contact pin assemblies and the jack assemblies are elastically and electrically connected in the mode that the insertion contact pins (3) penetrate through lip-shaped contact structures (7) to be fixed inside jacks (6). The elastic contact is high in reliability. When the elastic contact is used, a special clamp is used for installing the elastic contact, and therefore the elastic contact is rapid and convenient to use and high in efficiency.
