Assume that the board lock units 50c, 51c, 52e, 5
When the orientation of 3e is the same, the mounting strength of the PC card connector with respect to the circuit board 69 becomes directional,
The mounting strength is reduced in a direction perpendicular to the surface of the board lock portion. Also, each time a PC card is inserted or removed, an external force is applied to the PC card connector. Therefore, there is a possibility that the mounting position of the PC card connector on the circuit board is shifted in a direction in which the mounting strength is weaker while the insertion and extraction of the PC card are repeated.

However, the board lock section 5 on the plug terminal side
0c, 51c and board lock part 5 on the PC card insertion slot side
Since 2e and 53e are orthogonal to each other in different directions, the mounting strength of the PC card connector 3C to the circuit board 69 has no directivity and becomes uniform in each direction. Therefore, the circuit board 6 of the PC card connector 3C is repeatedly inserted and pulled out of the PC card.

As described above, according to the present invention, even when the external connection terminal is minute and easily deformed such as bending or falling down, it can be easily and reliably mounted on the circuit board as a connector and produced. It is possible to provide a card connector with improved performance. According to the sixth aspect of the present invention, since the operation button, which is a component separate from the eject operation rod, is attached to the operation button attachment portion at the tip of the eject operation rod, the card connector is completely removed except for the attachment of the operation button. The assembling work can be performed regardless of the user's operation button color specification. Assemble the card connector without the operation button, and install the operation button of a specific color according to the user's order This makes it possible to assemble the device more quickly according to the user's order than before, and it is possible to promptly supply the user with a card connector that matches the user's order.

According to a seventh aspect of the present invention, the connector body has a plate-shaped board lock member in the insulated housing, and the board lock member is fixed to the insulated housing by a board lock portion press-fitted into a through hole of the circuit board. The arm portion extending from the main body portion to be formed is configured to absorb the displacement of the position of the through hole of the circuit board from the position of the board lock portion by bending the arm portion. Even if the position of the through-hole is slightly shifted from the position of the board lock portion, the card connector can be normally mounted on the circuit board.

According to an eighth aspect of the present invention, the insulated housing has an arm accommodating portion for accommodating the arm, and the arm accommodating portion has a shape that allows the arm accommodated therein to bend. As a result, it is possible for the arm to bend in the direction in which the arm comes out of the arm housing, as well as in the direction in which the arm enters the arm housing. Regardless of the direction of displacement with respect to the position of the part, the card connector can be normally mounted on the circuit board.

According to a ninth aspect of the present invention, the fork-shaped board lock portions have different directions at two places on the plug terminal side and two places on the card insertion side and are orthogonal to each other. For this reason, the mounting strength of the card connector to the circuit board is not directional, and becomes uniform in each direction. Therefore, the card connector can be mounted on the circuit board without mounting strength. Therefore, it is possible to prevent the mounting position of the card connector on the circuit board from being shifted during repeated insertion and extraction of the card.
