Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model and beneficial effect are further described.
Referring to accompanying drawing 1-5, the embodiment 1 of elastic electric terminal connector of the present utility model comprises and is tabular, be used for the weld part 1 of connecting circuit plate and embrace wall 2 by the precompressed that two sides of this weld part extend upward the pair of opposing that forms, wall 2 common formation pedestals are embraced in weld part 1 and precompressed, one end of weld part 1 is connected with horizontally extending anti-creep tin portion 3, anti-creep tin portion 3 ends extend upward and form " C " type elastic portion 4, " C " type opening surface of elastic portion 4 is to pedestal, the horizontally extending drawing section 5 of elastic portion 4 terminal connections, the end of drawing section 5 gos deep into precompressed and embraces between the wall 2 and extend upward and form contact site 9, anti-creep tin portion 3, " C " type elastic portion 4, contact site 9 constitutes elastic arm together, contact site 9 comprises the section of extending upward 6 that connects successively, contact-segment 7 and downward extension 8, this downward extension 8 is provided with prestressed structure, this prestressed structure is for extending the extension arm 10 that is provided with on the section of prolonging 8 downwards, embrace two precompressed respectively perforate 11 is set on the wall 2, perforate 11 is the prestressing force fit structure, and itself and extension arm 10 cooperate makes elastic arm be in the prestressing force hold mode.
In other some embodiment of the present utility model, being positioned at precompressed embraces prestressing force fit structure on the wall 2 and can be arranged on two precompressed and embrace wall 2 slideway inboard and that extend at vertical direction and the pressing plate that is positioned at the slideway top, the width of the downward extension 8 of contact site 9 is less than the width between two described pressing plates, hanging arm 10 can slide up and down in slideway, hangs the cooperation of arm 10 and pressing plate and slideway and makes elastic arm be in the prestressing force hold mode.
