The housing has a protruding grid wall for supporting the projection of the metal cover when combined with the metal cover on the side, and a protective part for protecting the detection terminal and the switch terminal is formed on the rear side, the metal cover The protective part is formed to protect the detection terminal and the switch terminal, and a bent shape is formed on the solder surface soldered to the PCB while surrounding the housing to increase the solder cross-sectional area.

The micro SD header connector according to the present invention surrounds the exposed ends of the detection terminal and the switch terminal with the protection part of the metal cover and the protection part of the housing to prevent external interference or deformation during processing, and to prevent the side of the housing. The protruding grating wall formed on the metal cover supports the metal cover to prevent sagging of the housing assembly, thereby improving the flatness of the solder portion, and forming a bend on the solder surface of the metal cover to increase solder cross-sectional area, thereby improving solder characteristics. There is.

The technical problems achieved by the present invention and the practice of the present invention will be more clearly understood by the preferred embodiments of the present invention described below. The following examples are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

1 is an exploded perspective view of a micro SD header connector according to the present invention.

As shown in FIG. 1, the micro SD header connector according to the present invention provides a space for mounting the connection terminal 20, the detection terminal 42, and the switch terminal 44, and is coupled with the metal cover 30. A housing 10 forming a space (50 of FIG. 2) for mounting a micro SD card (not shown) and a micro SD card are combined with the housing 10 to form a space for mounting the micro SD card. The metal cover 30 for guiding the micro SD card so as not to be biased toward the switch side during insertion, the connection terminal 20 of the conductive metal mounted on the housing 10 and electrically connected to the terminals of the micro SD card, and the housing 10 And a card recognition unit comprising a conductive metal detection terminal 42 and a switch terminal 44 for detecting the insertion of the micro SD card.

Referring to FIG. 1, the housing 10 has a connection terminal mounting groove 12 for mounting eight connection terminals 20, a detection terminal mounting groove 14 for mounting the detection terminal 42, and a switch. A switch terminal mounting groove 16 for mounting the terminal 44 is formed, and when combined with the metal cover 10, a protruding grid wall 18 for supporting the protrusion 36 of the metal cover is formed on the side surface thereof. The rear side is provided with a protection unit 19 for protecting the detection terminal 42 and the switch terminal 44.

The connecting terminal 20 has a central portion 24 bent in a U shape so that both sides have elasticity, and one side protrudes to form a protrusion 22 contacting the terminal of the micro SD card, and the other side of the housing 10. It is supported by and forms a contact portion 26 which is soldered and electrically connected to the main PCB (not shown).

When the micro SD card is inserted into the metal cover 30, a space 50 formed by combining the protection unit 32 and the housing 10 to protect the detection terminal 42 and the switch terminal 44 protruding to the rear surface is inserted into the metal cover 30. A guide part 34 for guiding the card and a soldering part 38 soldered to the main PCB are formed.
