Two folder sidepieces of two elasticity side legs of metalwork and spring steel plate are provided with the arc lug accordingly, and the arc lug is in the end that metalwork forms opening, is beneficial to element to be connected and pegs graft with metalwork easily.
Be respectively equipped with fluting on the two elasticity side legs of metalwork.Be respectively equipped with on the two-clip lateral part of spring steel plate with two elasticity side legs on the corresponding groove of slotting position.Like this, the part that metalwork contacts with element to be connected forms 2 contacts, has improved connection reliability.
The afterbody upper end of metalwork also is provided with kink, is used to limit the stroke of lead to be connected.
The afterbody lower end of metalwork is provided with extension, and extension is connected with afterbody by connecting portion.The non-end that is connected with afterbody of extension is provided with continual-connecting-part.Syndeton such as spring that such structure helps this plug assembly and other form make up.
As the preferred technical solution of the present invention, reaching the angle that forms between the two-clip lateral part between the two elasticity side legs is acute angle, when Connection Elements such as insertion, can form big thrust.The length of two-clip lateral part is generally less than the length of two elasticity side legs, and the gap of the two-clip lateral part open end of spring steel plate is less than the integral thickness of metalwork two elasticity side leg opening ends, when spring steel plate and metalwork combination, can produce elastic deformation, two elasticity side legs are produced inside pressure.
Two-clip lateral part is straight shape or is curved shape.
3, beneficial effect: the plug assembly that is used to be electrically connected of the present invention has the following advantages: cooperate closely between (1) spring steel plate and the metalwork, overcome the little defective of prior art medi-spring steel disc active force; (2) owing to can be provided with fluting on the elasticity side leg of metalwork, can make to form at 2 between elasticity side leg and the element to be connected and be connected, be difficult for producing the phenomenon of becoming flexible; And such fluting helps heat radiation more, is particularly useful for by the bigger occasion of electric current.
