Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a clip-type memory card connector in which a circuit board is fixed at one end to lower the overall assembly height, and a memory card is inserted and connected to the other end.

[0002]

[Prior art]

 In the conventional memory card connector for inserting a memory card, the terminals attached to the connector are arranged symmetrically in upper and lower two rows. These terminals have contact terminals and welding terminals, and are bent at 90 degrees. Have been. The contact terminals are connected relatively to the connector belonging to the memory card to be inserted into the memory card connector, forming an electrical circuit, and the welding terminals are formed by surface mounting technology (SMT). The memory card and circuit board, which are welded to specific pads of the circuit board and inserted, form a telegraph circuit. However, in conventional memory card connectors, the terminals were sometimes welded to the circuit board, and the terminals could be damaged after long-term use. In addition, due to the development of electronic product manufacturing technology, products tend to be light and thin and small, and portable ones have become the mainstream in design.However, conventional memory card connectors are entirely welded to circuit boards. They were joined and could not lower the overall altitude when installed on a circuit board.

[0003]

[Problems to be solved by the invention]

 As can be seen from the above description, in the conventional memory card connector, the terminal may be damaged by long-term use only by welding the terminal and the circuit board. In addition, there is a disadvantage that when installed on a circuit board, the overall height cannot be lowered. Therefore, the challenge is to improve its structure, easily assemble it with the circuit board, secure it firmly, and at the same time keep the overall height as low as possible, without deforming the entire connector and providing an electromagnetic wave shielding effect. is there.

[0004]

[Means for solving the invention]

 In order to solve the above problems, the connector body of the clip-type memory card connector of the present invention has a terminal block on which a plurality of conductive terminals are installed. There are two shoulders facing each other in parallel to each other, and an installation space for inserting and installing a memory card is formed. A positioning pedestal extends at the end opposite to the end facing the shoulder installation space, and a positioning tank having a height approximately equal to the thickness of the circuit board is provided at a position of the positioning pedestal facing the circuit board. Are provided, and the circuit board can be inserted therebetween. A flat guiding tank integrated with the positioning tank is provided on the outside of the shoulder.The connector body is fitted along both sides of the circuit board facing the cut, and the guiding tank and the positioning tank are used. Since the circuit board surface can be firmly sandwiched, it can be easily assembled with the circuit board, and can be fixed firmly while lowering the overall height. In addition, since a metal chassis plate is provided between the two shoulders, the distance between the two shoulders can be fixed, thereby preventing the shoulder from being bent inward and deformed. In addition, since the conductive piece is placed in contact with the metal chassis plate, the static electricity generated when the memory card is inserted into the connector body and touches the chip on the chassis plate is discharged by the conductive piece. Therefore, an electromagnetic wave blocking effect and a grounding effect can be provided.
