How to scientific computing terminal insertion force? Calculation of Mg instrument for terminal insertion force are two ways through various kinds of experiments:
If there are no other mechanical settings (such as buckle convex point, etc.), the calculation method of inserting and pulling force is friction coefficient with positive pressure multiplied. Calculated by mechanical cantilever beam in mechanics of materials analysis method can be a positive pressure, or calculated using 3D analysis software. The friction coefficient through two materials in contact with the material, technology group mg instrument by querying the data handbook related to it.
Do the above method can only be a rough calculation, then how can accurately calculate?
At the same time the Sanmenwan Electric Engineering Department and draw a conclusion: most of the time is the shifting force measured by instruments inserted to get its value, and then to check the corresponding standard is, fine scar. In general, positive pressure is determined the main parameters of the performance of the connector plug, positive pressure can be obtained by the pure insertion force (not inverted, bump) was obtained by dividing the coefficient of friction.
Pluggable terminal blocks is composed of two parts: plug connection, a part of the wire pressing, and then inserted into another part, in this part of the welding to PCB board. This is connected with bottom of mechanical principle, the anti vibration design ensures the use reliability airtight product long-term connection and finished products. Socket can be installed with the ear, the ear can protect tab assembly and can prevent the splicing arrangement poor position to a great extent, and the socket design can guarantee the socket can be inserted into the parent right. The socket can also have assembly buckling position and locking button position. Assembly fastening position can play more firmly fixed onto a PCB board, a locking button can lock the maternal and the socket after the installation is complete. Insert socket method, various designs can match different maternal say: horizontal, vertical or inclined to the printed circuit board, can choose different ways according to the requirements of customers. You can select a metric gauge can also choose the standard wire gauge, is currently the most selling terminal types on the market.
Summary: the terminal insertion force can be achieved by increasing the unqualified bump or inverted, but positive pressure does not reach the design value will cause the increase of contact resistance, is a waste.
