The jig 33 is integrally formed at both ends of the grounding member 34 fixed to the upper surface of the casing. The distal end portion of the grounding member 34 includes a downward piece portion 35 that bends the grounding member 34 downward, and includes: The support piece portion 36 which is bent in the horizontal direction toward the outer side of the lower end portion 35 is bent upward to form the jig 33. The side plate portions 29 at both ends of the outer casing are inserted between the lower piece portion 35 and the jig 33, and the side plate portion 29 is prevented from being detached from the support shaft 3 2 by the jig 3 3, and the card is extruded at the jig 33 The locking window 37 is formed so that the locking projections 31 integrally formed on the side plate portions 29, 29" of the outer casing 12 by punching and r11 - 201119148 are engaged with the locking window 37, and the outer casing 12 is overlapped with In the state above the casing, the locking projection 31 is fitted to the locking window 37, whereby the casing 12 is not easily rotated in the vertical direction. Further, the tongue piece which is punched out by the formation of the locking window 37 is soldered to the ground terminal 39 which is "the substrate (not shown in the drawing) in which the connector is mounted". The grounding member 34 is integrally formed with a grounding joint 3, and its front end is inserted into the substrate insertion portion 20 of the casing 10 to form a grounding terminal that contacts the substrate A. At the outer casing 12, a substrate preventing and detaching mechanism is integrally provided at both end portions thereof. In the front side of the casing of the casing main body portion 28, that is, the strip-shaped spring piece portion 40 which is extended toward the front side from the edge portion on the opening side of the substrate insertion portion, the anti-drop mechanism has a U-shaped portion 40 which is folded downward toward the lower side. The elastic piece portion 4 1 of the shape and the substrate engagement claw 42 formed by bending the front end side of the elastic piece portion. The substrate engagement claw 42 is configured by an inclined piece portion 42a that extends the front end of the elastic piece portion 41 from the obliquely lower side: and the upward locking piece portion 42b, which is upwardly clicked The stopper portion 42b is formed by bending the distal end of the inclined piece portion 42a upward. Further, in the casing main body 28, at a position above the front end of the upward locking piece portion 42b, a retracting window opening 44 for allowing the piece 42b to move up and down is formed. Next, at least the distal end portion of the substrate engagement claw 42 is inserted into the substrate insertion portion 20 through the slit 45 "the opening is formed on the upper surface of the casing 1" -12-201119148. Although the slit 4 5 in this embodiment has a shape in which the front side, that is, the front side of the casing 1 is formed to open toward the front of the casing, it may be a window opening which is open toward the upper surface of the casing 1 . . In the connector of one of the substrates, the left and right edge portions ' of the sheet portion a are formed with an engagement claw fitting portion 46 that penetrates the upper and lower sides, and the insertion portion a is inserted into the connector at a specific depth in the connector. In the state where the engaging claw fitting portion 46 is disposed, the substrate engaging claw 42» is disposed at the outer casing 12 on the back side of the upward locking piece portion 42b, that is, the front side of the casing is integrally formed The front side movement restricting piece 50 0 that is downwardly protruded is a tongue which is formed by "cutting a C: font on the outer casing 1 to form a rectangular shape" and bending it downward. In this example, 'is a tongue that is bent after being punched out when the backing window 4 4 is punched out. Next, the function of the above FPC connector will be explained. Before the insertion of the substrate A, the outer casing 12 is superposed on the upper surface of the casing 1', and the elastic contact piece portion 23 of the joint 11 is formed to protrude into the substrate insertion portion 2''. At this time, the outer casing 12 is formed such that the locking projection is engaged with the jig 3 3 ' to prevent the movement in the vertical direction from being blocked. In the above state, the connector insertion piece a of the substrate A is inserted into the substrate insertion portion 20 of the casing. At this time, the elastic contact piece portion 23 of the joint π is pressed by the insertion piece portion a, and is moved in the retracting direction, and the elasticity of the elastic contact piece portion 23 is made in a state where the insertion piece portion a is inserted to a certain depth. The contact portion 25 is pressed into contact with the connection terminal 26 of the insertion piece portion & Similarly, the grounding terminal 38 is also pressed into contact with the grounding terminal 26a of the inserting piece -13-201119148 part a. When the insertion piece portion a is inserted, the front end edge of the insertion piece portion a is slid on the lower surface side of the inclined piece portion 42a of the substrate engagement claw 42, and the substrate engagement claw 42 is pushed upward. At this time, since the lower side movement restricting piece 43 is raised into the retracting window hole 44 of the casing main body 28, the substrate engaging claws 42 can be raised without being disturbed. Then, when the insertion piece a is inserted into the specific position, the substrate engagement claw portion 42 is dropped into the engagement claw fitting portion 46 of the insertion piece a to form a fitting "in this case, in the insertion piece" When the portion a has been inserted into the substrate insertion portion 20, when the removal force is applied to the substrate A for some reason, the front end side edge portion 46a of the engagement claw fitting portion 46 will contact the substrate engagement claw 42. The sheet portion 42b is locked upward to prevent removal. Once the above-mentioned removal force is applied, the substrate engaging claw 42 serves as a fulcrum for the base end portion of the elastic piece portion 41 as a fulcrum, and if the applied removal force is greater than the resistance, the substrate engaging claw 42 will form a force acting in a direction in which the elastic piece portion 41 is floated, and a force acting in a direction in which the upward locking piece portion 42a is pulled toward the front side of the casing, at this time, due to the upward locking portion The front side movement restricting piece 50 is present on the back surface of the 42a. Therefore, when the board engaging claw 42 is moved in the board pulling-out direction, the back side of the upper locking piece portion 42b abuts against the restricting piece 50 to resist pulling toward the substrate. The power of the direction is the structure against the powerful removal force. Therefore, even in the case where the substrate is engaged with the 201119148 claw in the "very thin outer casing having a thickness of 0.1 mm or less" by punching, it is possible to resist strong displacement. In addition to force, it achieves a safer product in miniaturization. Further, when the inserted substrate A is pulled out, the outer casing 12 is erected in a state in which the two side plate portions 29 of the outer casing 12 are released by bending the jig 3 3 in the opening direction. The direction above the housing rotates. Thereby, the substrate engagement claws 42 are detached from the substrate insertion portion 20 of the casing 10, and the restraining of the drawing direction of the substrate A is released, and a state in which the paper can be easily pulled out is formed.
