sim card connector principle of operation

                                            sim card connector principle of operation

In the production of sim card connector electronic components, first understand the basic working principle of SIM card connector and production steps, 

first prepare the manufacture of SIM card connector insulator and terminal mold, automatic assembly machine and other production equipment, as well 

as electroplating equipment. SIM card connector through these equipment for the insulator molding engineering, manufacturing terminal stamping work.

SIM card connector in the contact terminal internal metal conductor is the core part of the contact terminal, it will power, signal, etc. transfer and contact 

with other parts on, so the contact terminal internal metal conductor must have good conduction performance. If the contact part design is not reasonable,

 material selection error, size substandard, or plating layer processing improper, will cause the connector contact terminal contact poor.

SIM card connector contact terminals need to be fixed in a specific position in order to achieve a stable connection, if not in accordance with the perfect 

or product plugging life leads to poor fixing, the light affects the contact reliability caused by instantaneous power failure, the serious is the product 

disintegration. Disintegration refers to the plug state, due to materials, design, technology and other reasons resulting in unreliable structure caused by 

the normal connection between the plug and socket disconnection.

SIM card connector contact terminal insulator is the role of the contact parts to maintain the correct position of the arrangement, and is between the 

connector and the connector, between the connector and the shell of mutual insulation. Solid insulators must have excellent electrical properties, mechanical 

properties and process performance. Especially with the widespread use of highly sophisticated, miniaturised terminal blocks, the effective wall thickness of 

the insulator is becoming thinner and thinner. This places more stringent demands on the insulation material, the precision of the injection mould and the 

moulding process.
