The housing 101 includes a body (first case body) 102 made of an insulating material (resin material) and a cover (second case body) 103 made of a conductive material (metal material) fitted to the body 102. A slot entrance 104 into which the memory card 100 is inserted is formed in the front side, and the card 100 is inserted and received from the slot entrance 104 into the internal space of the housing 101. That is, the housing 101 forms a slot 105 into which the card 100 is inserted and received.

  The connector also includes a plurality of connection terminals (contacts) 106 for electrically connecting the card 100 and the circuit board of the electronic device. Each terminal 106 is formed of an elongated plate piece made of a conductive material (metal material), and is integrally attached in parallel to the rear portion of the body 102. The front half of each terminal 106 can be elastically displaced up and down so that the rear portion of the body 102 can be elastically displaced vertically. To project from the front surface (the back bottom surface of the slot 105) in an upwardly inclined manner and to contact each electrode of the card 100 inserted and accommodated in the slot 105 at the tip of each elastic arm to be electrically connected The rear end portion of each terminal 106 protrudes from the body 102 to the outside of the housing 101, and is electrically connected to each electrode of the circuit board on which the connector is mounted at each protruding end portion by soldering. It has an external contact 108 for connection to.

  Further, the connector includes a so-called push-in / push-out type eject mechanism 109 as an internal mechanism. The eject mechanism 109 is slidably disposed in the front-rear direction at an inner side end portion of the body 102, has a card receiving portion 110 protruding toward the inside of the body 102 at the rear end portion, and is formed of a leaf spring. The intermediate portion has a recess 113 that accommodates and holds the card half-lock member 111 and protrudes toward the inside of the body 102 so that the locking claw 112 at the tip of the elastic arm portion of the half-lock member 111 can be retracted. The slider 119, which is formed in a substantially heart shape, has a cam groove 118 at the front portion connecting the starting portion 114 at the rear end top portion and the locking portion 115 at the front end recess portion by the forward path 116 and the return path 117, and the slider 119. It consists of a coil spring 120 that is always urged rearward and an elongated metal bar that is bent at both ends at right angles in one direction. The front end bent part can be pivoted around this axis. , And a cam pin 121 that is slidably fitted into the cam groove 118 with the rear end bent portion (swinging end portion) being slidably inserted into the cam groove 118.

Thereby, the insertion card 100 and the slider 119 are engaged and connected in the card insertion / removal direction (the state shown in FIG. 7). In this state, when the insertion card 100 is further inserted into the slot 105, the receiving portion 110 is pressed backward, and the slider 119 slides backward against the coil spring 120 from the ejection position integrally with the insertion card 100, The slider 119 slides to the most pushed position where the rear end of the slider 119 comes into contact with the rear end of the body 102 (the state shown in FIG. 8 except for the cam pin 121 indicated by an imaginary line). When the insertion force of the card 100 is released at this time, the slider 119 is pushed back from the most pushed position by the coil spring 120. Through a series of operations from the eject position of the slider 119, the rear end bent portion of the cam pin 121 is introduced and locked to the locking portion 115 from the starting portion 114 of the cam groove 118 through the forward path 116, and the slider 119 slides forward. The movement is restricted at a position (card mounting position) slightly before the most depressed position, and the slider 119 is held at the card mounting position with respect to the body 102 (locked). As a result, the insertion card 100 engaged and connected to the slider 119 in the card insertion / removal direction is accommodated and held in the card mounting position of the slot 105, and at the same time, each electrode of the insertion card 100 and the internal contact 107 of each terminal 106 contact each other. Are electrically connected (state shown in FIG. 9).

  Further, when the insertion card 100 is housed and held at the card mounting position of the slot 105 (the state shown in FIG. 9), the insertion portion 100 is inserted, whereby the receiving portion 110 is again pushed backward. Then, the slider 119 slides backward from the card mounting position against the coil spring 120 integrally with the insertion card 100, and slides to the most pushed position. By pushing the slider 119 from the card mounting position to the most pushed position, the rear end bent portion of the cam pin 121 is released from the locking portion 115 of the cam groove 118 and is introduced into the return path 116, and the slider 119 moves forward. The sliding restriction is released (the state shown in FIG. 8 except for the cam pin 121 indicated by the solid line). By releasing the insertion force of the card 100 at this time, the slider 119 is slid forward from the most pushed position by the coil spring 120 and returned to the eject position, and is engaged and connected to the slider 119 in the card insertion / removal direction. The inserted card 100 is ejected to the eject position of the slot 105 and held at the eject position (state shown in FIG. 7). The insertion card 100 held at the ejection position of the slot 105 is pulled out by grasping the front end protruding from the slot entrance 104, so that the locking claw 112 of the half-lock member 111 is used for half-locking the insertion card 100. The half-lock is released from the engagement groove 123, and is removed from the slot 105 through the slot entrance 104.

  The connector is mounted on the circuit board in a state where the external contacts 108 of the terminals 106 are soldered and electrically connected to the electrodes of the circuit board, and is inserted into the slot hole formed in the housing of the electronic device. It is attached to an electronic device so as to open the entrance 104, and exhibits a function of electrically connecting the memory card 100 inserted and accommodated in the slot 105 from the slot entrance 104 to the circuit board of the electronic device, and entering electronic data. Output is possible.

  In addition, connectors that cannot be mounted on a circuit board due to the downsizing of small electronic devices and component placement are flexible printed circuit (FPC) and flexible flat cables (Flexible). A flat cable (hereinafter referred to as “FFC”) is electrically connected to a circuit board via a cable and is attached to a housing of a small electronic device. In this case, the connector is an FPC in a state where the external contact 108 of each terminal 106 is soldered and electrically connected to each electrode (conductor portion) of “FPC or FFC” (hereinafter referred to as “FPC / FFC”). Surface mounted on / FFC. (For example, refer to “Patent Document 1”.)

  However, a soldering process for surface mounting the connector on the FPC / FFC is required separately from the soldering process with the circuit board, and when the connector housing is attached to the housing of a small electronic device, the connector is already attached to the connector. Since the FPC / FFC is soldered, it is difficult to mount the FPC / FFC in a narrow space, and it is difficult to route the FPC / FFC. There are problems such as.

Conventionally, as a connector for connecting the FPC / FFC to the circuit board, there is a ZIF (Zero Insertion Force) type connector in which the FPC / FFC can be attached to the connector with zero insertion resistance (see, for example, “Patent Document 2”). .
