What is doing is provided (for example, patent document 1).

  As shown in FIGS. 14 to 16, this type of header-type card connector has a housing formed of a mold case 51 and a shield cover 52 that encloses the upper surface and left and right side surfaces of the mold case 51. A card insertion portion 53 is formed in a groove shape, and the upper side thereof is covered with a shield cover 52.

  A base-resistant fixing portion 54 is formed by bending both side edges of the shield cover 52 to the lower side of the mold case 51 and soldering to the base, and by soldering it to the pattern on the surface of the base C, it is grounded. As a result, the entire header type card connector is fixed to the substrate C.

  Further, this header type card connector is provided on the back side of the card insertion portion 53 in order to place the signal transmission contact 55 exposed in the card insertion portion 53 in a non-live line state when the memory card B is inserted and removed. In addition, a timing switch 56 that is turned on / off in accordance with the contact timing of the contact 55 with respect to the signal transmission terminal of the memory card B is provided.

Japanese Patent Laid-Open No. 2003-77565

  In such a conventional header type card connector, since the terminal portions 57b and 58b of the timing switch 56 are located at the front corners, the arrangement of the board connection terminal portions on the bottom surface of the mold case is limited, and the degree of design freedom is increased. In addition to being low, there is a problem that a necessary spring length cannot be obtained due to dimensional constraints of the operation side contact spring 57 and sufficient elastic characteristics cannot be obtained.

  Further, in the conventional header type card connector, the terminal portions 57b and 58b of both contact springs 57 and 58 of the timing switch 56 are exposed at the corners on the bottom front edge side of the mold case 51. The base-resistant fixing part 54 of the shield cover 52 cannot be provided. For this reason, conventionally, as shown in FIG. 16, two points avoiding the corners or not shown in the figure, but at positions excluding one corner. It was unavoidable.

  For this reason, the moment due to the external force applied to the housing on the outer end of the memory card is concentrated on the terminal portions 57b and 58b of the timing switch 56, thereby causing concerns such as solder peeling, and the shield cover. Since the arrangement of the anti-base-fixing portion 54 of 52 is biased, the external force from the memory card also acts on the soldering portion between the signal transmission contact and the base pattern, resulting in low durability. There was a problem.
