Problems solved by technology
[0019] In addition, in the above-mentioned conventional technology, when the card body is inserted, the elastic contact piece part is pressed by the card body and elastically deformed, and the movable end part acquires a reaction force at the bottom of the insertion groove and slides accordingly. The bottom of the insertion groove made of insulating synthetic resin is scratched by the edge portion of the sliding movable piece, and the movable end is caught in the cut portion of the bottom of the insertion groove, thereby elastically contacting the predetermined position of the piece. Obstacles occur in the movement, which may cause deformation of the elastic contact piece

Embodiment Construction
[0062] Next, based on Figure 1 to Figure 12 The shown embodiment explains the method of manufacturing the card connector of the present invention. In addition, reference numeral 1 in the figure is a card connector, and reference numeral A is a card body such as an IC card.
[0063] For example image 3 As shown, the card body A is an IC card, and is formed in a rectangle whose overall length is longer than the overall width of the card, and a positioning portion Aa of a shape cut off in an oblique direction is formed at one corner of the rectangle.
[0064] On one side of the card body A, a pair of signal terminal rows are formed by arranging a plurality of signal terminals a1, a1 ... in the card width direction, and arranged side by side at intervals in the card length direction. Moreover, in this card body A, even if the outer shape is the same shape, but the number and arrangement of the signal transmission terminals a1, a1 ... are different, for example, image 3 (a) i...

The invention provides a manufacturing method for a card connector. The card connector can realize reduced height and a contact can stable act when a card body is inserted into a housing. After a stamping processing procedure of molding a stamping component (P1) of one side having a contact (4) of one side and a component (12) contacted in a sliding manner which is connected with the contact of one side via a connecting sheet (13) and a stamping component (P2) of the other side having a contact (5) of the other side, the two stamping components (P1), (P2) move and a movable end (33) of the contact (5) of the other side is configured on the component (12) contacted in a sliding manner, and insertion molding is performed in such a state, the contact (4) of one side, the component (12) contacted in a sliding manner and the contact (5) of the other side are installed in a bottom plate part made of insulating synthetic resin, and then, the connecting sheet (13) that connects the contact (4) of one side and the component (12) contacted in a sliding manner is cut off.
Description
technical field [0001] The present invention relates to a card connector for connecting a card body such as an IC card or a flash memory card to a printed wiring board mounted on electronic equipment such as a mobile phone or a smart phone. Background technique [0002] Card bodies such as IC cards and flash memory cards are used as external storage media for electronic devices such as mobile phones and smartphones, and the card bodies and printed wiring boards mounted on the electronic devices are electrically connected via card connectors. [0003] In the past, this kind of card connector has: housing, it has the card body inserting part that inserts the card body such as IC card; It is made of plate material. By inserting the card body into the card body insertion part, the signal transmission terminals (soldering points) formed on one side of the card body contact the elastic contact pieces of the corresponding contacts, so that the printed circuit wiring board and the c...
