In order to solve the problem that the existing contact mode takes an edge with the width of 0.2mm as a contact part, the risk of falling off and blocking of a spring arm is extremely high, and the contact part edge of another device contacted with the spring arm is calculated to have 75% area contact when 1-degree deflection occurs, and only about 50% area contact when 2-degree deflection occurs, so that the spring arm has high probability of falling off under the conditions of vibration and assembly errors, the blocking is caused or the spring arm is contacted with an element with a non-same function, and electric transmission failure is caused. The deflection of the contact part is caused by the fact that the device is formed by stamping metal, and the stress is difficult to eliminate according to the prior structure due to stress and precision factors, so that the forming precision is improved, and the cost is greatly increased; meanwhile, impedance and crosstalk are very important consideration factors in a high-speed connection system, the quality of electric signal transmission is directly affected, and the defects of poor impedance adaptation, poor crosstalk and small guiding capability caused by the large characteristic width and short guiding of the original pressing plate are needed to be solved.
