How to computing terminal insertion force scientific?For terminal insertion force calculation of the Shanghai Elinker technology experts through various experimental get two ways:If there is no other mechanical Settings (such as torque, salient point, etc.)Calculation inserted  force method is to use positive pressure multiplied by the coefficient of friction. Positive pressure can through the material mechanics of the cantilever beam mechanics analysis method to find  or use 3 d analysis software calculation. Coefficient of friction to through the two contact material is qualitative, three bay electrical technology group through the inquires the relevant data from manual.

The above calculation method can only do a rough calculation, that how to get accurate calculation?

Shanghai Elinker electrical engineering department  draw a conclusion: a lot of time is through the instrument is inserted dial force ways to get the value, to check the corresponding standard is yao fine Ban. Usually, positive pressure is decided to connector plug performance of the main parameters, the positive pressure can through the pure inserted dial the force (no backoff, salient point) divided by friction coefficient to get.Plug type terminal consists of two parts plug connection and become part of the line pressure, and then inserted into another part, this part is welding to PCB board.This joint bottom mechanical principle, the anti vibration design to ensure that the product long-term air tight connection and the use of product reliability. Socket ends can be added a mounting ears, assembly ear in the very great degree can protect the sheet and can prevent the sheet arrangement position not beautiful, at the same time this kind of socket design can guarantee socket can right into the parent.. Socket can also have assembly button bit and lock button bit. Assembly button bits can play more firmly fixed to PCB board, lock button bits can completed lock maternal and socket after the installation. All kinds of socket design can match different parent insertion method, such as: horizontal, vertical or inclined to printed circuit boards, etc., can according to the demand of the customers choose a different way. Can choose metric wire gauge can also choose to standard gauge, is the best  sell like hot cakes of terminal type on the market.

Conclusion: terminal insertion force rejected by adding more salient point or torque method, but positive pressure can not reach the design value can make the contact resistance increases, is a waste.
