Summary of the invention
The object of the present invention is to provide a kind of grounding reed, the problem that can cause the contact engaging and separating force between the inside and outside metal shell of connector sharply to increase to solve existing grounding reed.
In order to address the above problem, grounding reed of the present invention is by the following technical solutions: a kind of grounding reed, comprise the substrate of strip, on described substrate, be laid with strip hole and in strip hole, be provided with elasticity mask tape along fore-and-aft direction, extend along the left and right directions of substrate in described strip hole, between the two ends of elasticity mask tape, there is an arcuate segment, the upper surface of substrate is protruded at the top of described arcuate segment, and one end one that the left and right end of elasticity mask tape protrudes from lower surface and the left and right end of substrate is fixed on substrate.
Being fixed on substrate of the left end of described elasticity mask tape, the right side edge of substrate is provided with turning edge of downward turnover, described in the lower surface that turns edge concordant with the lower surface of the left end of elasticity mask tape.
In its forward and backward two ends one of described substrate is provided with the pin overhanging along fore-and-aft direction, in another be provided with for its pin or hang after the pin bending on adjacent grounding reed with it into hanging hole.
Because grounding reed of the present invention is laid with strip hole and is provided with elasticity mask tape in strip hole along fore-and-aft direction on its substrate, between the two ends of elasticity mask tape, there is an arcuate segment, the upper surface of substrate is protruded at the top of described arcuate segment, and one end one that the left and right end of elasticity mask tape protrudes from lower surface and the left and right end of substrate is fixed on substrate; Therefore in the time of stress deformation, what described elasticity mask tape produced is the trend flattening gradually, elastic force increases gently without big ups and downs, make corresponding product, as can be softly plugged between the inside and outside housing of electric connector, solve the problem that the contact engaging and separating force between the inside and outside metal shell that existing grounding reed can cause connector sharply increases.
