Method for assembling card holder connector and card holder connector using the method

Abstract

The invention provides a method for assembling card holder connectors. The method comprises the following steps that: an insulating body and a plurality of conductive terminals are provided, wherein the insulating body is provided with a plurality of terminal holding holes and through grooves; the inside of each terminal holding hole is provided with a first space, a second space and a third space; the first space comprises a first wide space and a fist narrow space; each conductive terminal has a wide fixed part and a narrow fixed part; each wide fixed part extends downwards to form a weldedpart; the conductive terminals are pushed forwards to enter the terminal holding holes, so as to position the wide fixed parts respectively in the first wide spaces, position the narrow fixed parts respectively in the first narrow spaces and position the welded parts just above the through grooves; when the conductive terminals are pushed down, the narrow fixed parts fall to the second spaces, and the welded parts are positioned in the through holes and close to the back sides in the through holes; and the conductive terminals are pushed forwards till the welded parts push against the front sides in the through holes, so as to position the conductive terminals and ensure that the wide fixed parts enter the second spaces partially at least. The method for assembling card holder connectors does not damage the structure of the insulating body and is convenient for mechanized assembly.

Description

Assembly method of card socket connector and card socket connector using the assembly method 【Technical field】 The invention relates to an assembly method of a socket connector and a socket connector using the assembly method. 【Background technique】 At present, the multi-in-one card socket connectors used in the industry generally include the following two methods for assembling terminals by insert molding or main body thermal fusion: One is to assemble the terminals from top to bottom, that is, the terminals are arranged in the upper and lower rows, and the upper and lower rows of terminals are staggered and assembled on the insulating body of the card connector. Rows of terminals pass through. In this case, the thickness of the plastic retaining wall between the upper row of terminal receiving grooves and the preset channel is not enough, which weakens the strength of the insulating body and is easily deformed and damaged. During the mechanized assembly process, if the ...

Problems solved by technology

One is to assemble the terminals from top to bottom, that is, the terminals are arranged in the upper and lower rows, and the upper and lower rows of terminals are staggered and assembled on the insulating body of the card connector. Rows of terminals pass through. In this case, the thickness of the plastic retaining wall between the upper row of terminal receiving grooves and the preset channel is not enough, which weakens the strength of the insulating body and is easily deformed and damaged. During the mechanized assembly process, if the machine is slightly operated carelessly, it will Damage to the plastic retaining wall is not conducive to mechanized assembly

The other type is to assemble the terminals from the back to the front, and the terminals are arranged in front and rear rows. In this way, the thickness of the plastic retaining wall between the adjacent front and rear row terminal receiving grooves is not enough, and there are also the problems caused by the aforementioned insufficient thickness.
