I am sorry. An end 51 of the printed circuit board projects from the electronic circuit housing 50, and a tubular hood 52 is formed so as to surround the end 51. The inner peripheral surface of the hood 52 is formed along the outer shape of the outer housing 20, has a groove 53 into which each rib 20a can be inserted, and has a groove-like arm insertion into which the lock arm 22 can be introduced and locked. The portion 54 is formed so as to project upward. Further, an introduction cam 55 is formed so as to project on the inner surface side of the hood 52 corresponding to the notches 23 formed on the upper wall and the lower wall of the outer housing 20, and the introduction cam 55 goes toward the inner side. The protruding height is high. In addition,
Terminals 51a are formed on both surfaces of the end portion 51 of the printed circuit board so that the end portion of the printed line has a strip shape corresponding to the position where the communication port 35 of the inner housing 30 is formed.

Next, the operation of this embodiment having the above configuration will be described. When the card edge connector 10 is assembled, the terminal fitting 41 is inserted into the terminal housing chamber 33 of the inner housing 30 through the insertion port 34. At this time, by inserting the abutting portion 41a toward the inner peripheral wall of the terminal accommodating chamber 33 in which the communication port 35 is formed, the abutting portion 41a is inserted into the communication port 35 when the terminal fitting 41 is pushed.
More prominent. The terminal fitting 41 may be inserted after the card edge connector 10 is assembled.
On the other hand, with the opening on the rear surface side of the outer housing 20 facing upward, the end 42b of the spring member 42 facing downward and the central portion 42 facing upward, the central portion 42 is formed on the inner surface of the outer housing 20. The outer holding member 24 is hooked. In this state, both ends 42b of the spring member 42 are open toward the upper wall and the lower wall on the inner side of the outer housing 20.

The pair of inner housings 30 accommodating the terminal fittings 41 as described above are inserted into the outer housing 20 with the sides where the communication ports 35 open facing each other. At this time, the spring receivers 32 of the respective inner housings 30 are inserted so as to sandwich the spring member 42. The notch 31a formed in the bearing 31 of the inner housing 30 is attached to the outer housing 2
When the inner housing 30 is pushed in by bringing it into contact with the rotating shaft 25 of 0, and the inner housing 30 is pushed in, the rotating shaft 25 enters the bearing 31 through the notch 31a. Thus, the cutout 3
Since 1a is formed so as to open in the insertion direction of the inner housing 30, the inner housing 30 can be mounted at the same time as being accommodated.

When the inner housing 30 is pushed in, the spring bearings 32 come into contact with the inner side surfaces of the outer housing 20, so that the spring members 42 sandwiched between the spring bearings 32 of the respective inner housings 30 are concerned. The inner housings 30 are urged so as to push open both inner housings. Further, the spring member 42 has the end portion 42.
At the center portion 42a, the front end of the spring receiver 32 is caught at b.
Since the outer side holding member 24 is hooked on the rear surface side of the outer side holding member 24, the rotating shaft 25 is always rotated without being displaced in the front-rear direction.
Is used as a fulcrum to open the inner housing 30. In this way, the card edge connector 1
When 0 is assembled, it is inserted into the hood 52 protruding from the electronic circuit housing 50 as shown in FIG.
When each rib 20a of the outer housing 20 is aligned with the groove 53 of the hood 52 and is gradually inserted from the front wall side, the introduction cam 55 is inserted into the notch 23 of the outer housing 20, but is projected. Since the height is low, it only acts to align the outer housing 20 and does not approach the inside. On the other hand, both inner housings 30 are rotated by the action of the spring member 42 so as to be separated from each other with the rotation shaft 24 as a fulcrum, and a space is formed between them. Therefore, even if the end portion 51 of the printed circuit board enters the outer housing 20 through the insertion opening 21 formed in the front wall of the outer housing 20, the end portion 51 is only in light contact with the contact portion 41a.

However, when the guide cam 55 is further pushed in and the portion of the introduction cam 55 having a high protruding height is inserted into the notch 23 as shown in FIG. 3, the front end corner of the inner housing 30 is introduced. Abut the slope. The introduction cam 55 is formed on the upper and lower inner surfaces of the hood 52,
Since the protruding height increases toward the back, both inner housings 30 lean toward each other when the front end corner portion of the inner housing 30 abuts the inclined surface of the introduction cam 55 and is pushed in this way. I have to be close to him. As they come closer to each other, the contact portion 41a of the terminal fitting 41 protruding through the communication port 35 is strongly pressed against the terminal 51a formed on the surface of the end portion 51 of the printed board. However, since the inner housing 30 itself presses the terminal fitting 41 against the end portion 51 of the printed circuit board while rotating around the rotation shaft 25 and the bearing 31, the terminal fitting 41 is substantially perpendicular to the end portion 51. It is pressed at an angle close to. When the contact portion 41a is pressed in this way, the contact portion 41a is naturally pressed down, so that deformation or the like can be avoided.

When the outer housing 20 is inserted into the hood 52, as shown in FIG. 4, the inner housings 30 face each other substantially in parallel, and the contact portion 41a sandwiches the end portion 51 of the printed circuit board in the center and the terminal 51a. It will be in the state of being connected to. Since the end portion 51 is sandwiched from both sides, it can be positioned in the center. in this way,
The inner surface of the housing-shaped outer housing 20 and the conductive terminal 4
A rotary shaft 25 and a cylindrical bearing 31 are formed on the outer surface of the inner housing 30 that accommodates 1 and both are rotatably held in combination. At this time, the notch 31a is formed on the peripheral wall of the bearing 31 in the insertion direction.
When the inner housing 30 is inserted, the notch 31a is pressed against the rotary shaft 25 to assemble the two. Further, the spring member 42 is the inner housing 30.
The abutting portion 41a in a direction in which the abutting portion 41a moves away from the terminal 51a, and the end portion 51 of the printed circuit board is moved to
When the insertion is started in 0, the end portion 51 has the contact portion 41a.
However, the introduction cam 55 formed on the hood 52 surrounding the end portion 51 rotates the inner housing 30 toward the end portion 51 side when pushing the contact portion
1a and the terminal 51a are strongly pressed and connected.
