Utility model content
The purpose of this utility model is to provide that a kind of pre-determined bit parts are not yielding, the contact flat spring of accurate positioning.
For this reason, the utility model provides a kind of contact flat spring, contact flat spring comprises tabular fixed part, from the tightening part that described tabular fixed part one end inverse bending is formed, and to be inclined upwardly the elastic arm extended to form from described tightening part, described elastic arm comprises the rake being inclined upwardly and extending to form, be formed at the contact site on described rake top, and from the barb that described contact site extends to form after described tabular fixed part side bending, described barb rear end both lateral sides has extended to form pre-determined bit portion, described tabular fixed position upwards turns down in both sides, described pre-determined bit portion and is formed with two flank section, described two flank section offer the precompressed hole in described pre-determined bit portion, collecting location.
Described elastic arm also comprises and connects described tightening part and the horizontal part being parallel to the extension of described tabular fixed part, and described rake extends to form from described horizontal part end tilts.
Described flank section comprises the base portion that upwards extends and upwards extend to form pre-splenium again after the inside bending in described base portion upper end, and the width between described two pre-spleniums is less than the width between described two base portions.
Described base portion and described pre-splenium are crossed in described precompressed hole.
Width between described two base portions is suitable with the width of described tightening part.
The pre-determined bit portion transverse width of described elastic arm is not more than the width between described two base portions.
Described contact flat spring is stamped to form by plate-shape metal, and described two flank section well turn down formation afterwards in the pre-determined bit portion punching press of described elastic arm end.
Relative to prior art, the utility model contact flat spring is in the both lateral sides upwards bending formation flank section of described tabular fixed part away from described tightening part, and precompressed hole is offered in described flank section, the horizontal pre-determined bit portion extended in described precompressed hole is set realizes precompressed by extending to position between described two flank section in the inclination of described elastic arm simultaneously, described precompressed pore structure is closed, and pre-compressed effect is reliable and stable; Meanwhile, the inside bending above described base portion of described two flank section extends to form pre-splenium, and described base portion and described pre-splenium are crossed in described precompressed hole, while prepressing structure is arranged, does not widen the size of product.

Embodiment
The tightening part 20 refer to shown in Fig. 1, Fig. 4, the utility model contact flat spring comprises tabular fixed part 10, being formed from described tabular fixed part 10 one end inverse bending and being inclined upwardly the elastic arm 30 extended to form from described tightening part 20.
Described elastic arm 30 comprises and connects described tightening part 20 and be parallel to the horizontal part 31 that described tabular fixed part 10 extends, the rake 32 extended to form that to be inclined upwardly from described horizontal part 31 end, the contact site 33 being formed at described rake 32 top and the barb 34 extended to form after described tabular fixed part 10 side bending from described contact site 33 and the pre-determined bit portion 35 extended to form from described barb 34 rear end both lateral sides.The end of described barb 34 is that oblique described tightening part direction extends to form downwards, in its natural state, is formed with space between described barb 34 and described fixed part 10.
Refer to shown in Fig. 2, Fig. 3, Fig. 5, described tabular fixed part 10 upwards turns down away from the both lateral sides of described tightening part 20 one end and forms flank section 40, and described flank section 40 comprises the base portion 41 that upwards extends and upwards extends to form pre-splenium 42 from described base portion 41 upper end again slightly toward after interior bending.Described flank section 40 offers the precompressed hole 43 in the pre-determined bit portion 35 for accommodating described elastic arm 30, described base portion 41 and pre-splenium 42 are crossed in described precompressed hole 43.The width of described base portion 41 is suitable with the width of described tabular fixed part 10 and described tightening part 20, the width of described pre-splenium 42 is less than the width of described base portion 41, and the transverse width in the pre-determined bit portion 35 of described elastic arm 30 is not more than the width between described two base portions 41.Described pre-splenium 42 is formed with stage portion 44 with the bending part of described base portion 41.
