DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention comprises an insulator and a plurality of contacts, the details of which are as follows. First, the insulator has a step shape connected to the bottom surface, the side wall, and the top surface, and the side wall is formed to have a height dimension substantially equal to the thickness of the printed circuit board. The printed circuit board has one side as the side wall. And a plurality of contact slide holding portions, each of which is formed back to back with the substrate mounting portion to be abutted and mounted so that the back side of the terminal electrode forming surface is in contact with the bottom surface. It has a structure. Also,
Each of the plurality of contacts is provided at one end thereof and is provided at a contact portion for contacting and connecting to a corresponding one of the plurality of terminal electrodes of the printed circuit board, and is provided at the other end and connected. A connecting portion for connecting to a corresponding electrode of the target circuit, and extending after being connected to the contact portion,
And a holding portion connected to the connecting portion.The holding portion is integrally formed with an elastic conductor, and the holding portion is folded back. A state in which the contact portion is in pressure contact with the upper surface of the substrate mounting portion of the insulator until the straight portion is slid into the corresponding contact slide holding portion of the insulator and reaches the contact final deployment position. In this state, the printed circuit board is mounted on the substrate mounting portion, and then, the slide is inserted until the contact final deployment position is reached.
The contact portion presses and contacts the corresponding terminal electrode of the printed circuit board to hold the printed circuit board.

With such a configuration and structure,
Without worrying about multiple contacts, simply attach the printed circuit board to the board mounting section of the insulator,
A plurality of contacts need only be pushed into the contact final deployment position with respect to the insulator, and the shape when the contacts are slid and inserted is not changed from the temporary stop position to the printed board holding position (contact final deployment position). Since these contacts can be inserted smoothly, these contacts do not buckle or deform, and the printed circuit board can be easily mounted, held and fixed.

The second embodiment of the present invention is the same as the first embodiment.
In addition to the above embodiments, a plurality of contacts are held and fixed so that the plurality of contacts can be simultaneously slid into the corresponding contact slide holding portions of the insulator so that the folded linear portions of the holding portions are slidably inserted. And a slide insulator.

(A)-(c) is sectional side view which shows the printed board mounting, holding | maintenance procedure. The first embodiment includes an insulator 100 and a plurality of contacts 200, and details thereof are as follows.

The insulator 100 has a stepped shape connected to the bottom surface 111, the side wall 112, and the upper surface 113, and the side wall is formed to have a height dimension substantially equal to the thickness of the printed circuit board 600. The substrate mounting portions 110 are mounted such that the terminal electrode forming sides abut against the side walls and the back surfaces of the plurality of terminal electrode forming surfaces are in contact with the bottom surface 111. Each of the substrate mounting portions 110 is formed back to back with the substrate mounting portion 110. , A plurality of contact slide holding parts 12
0, and a plurality of connecting portion accommodating chambers (both names and symbols are not shown) connected to the plurality of contact slide holding portions 120, respectively.

Each of the plurality of contacts 200 has a contact portion 210 provided at one end thereof for contacting and connecting to a corresponding one of a plurality of terminal electrodes (not shown) of the printed circuit board 600, And a connecting portion 220 for connecting to a corresponding electrode of a circuit to be connected (not shown). The connecting portion 220 is connected to the contact portion 210 and then extended in a U-shape (also a U-shape). And a holding portion 230 that extends linearly until it passes a position facing the contact portion 210 and that is further folded back into a U-shape to be connected to the connection portion 220, and is integrally formed of an elastic conductor (metal plate or the like). The linear part of the holding part 230 is the contact slide holding part 120 of the insulator 100.
And the connecting portion 220 is housed in the connecting portion housing chamber, and the contact is finally arranged at a position (a position where the U-shaped bottom portion of the contact portion 210 side contacts the insulator 100).
In the meantime, the contact portion 210 is temporarily stopped in a state where the contact portion 210 is in pressure contact with the upper surface 113 of the substrate mounting portion 110 of the insulator 100. In this state, the printed circuit board 600 is mounted on the substrate mounting portion 110. The contact portion 210 is pressed into contact with the corresponding terminal electrode of the printed circuit board 600 to hold the printed circuit board 600 by being slid and inserted until the contact final arrangement position is reached.

In the first embodiment, first, each of the plurality of contacts 200 is temporarily stopped at a position where the contact portion 210 thereof comes into pressure contact with the upper surface 113 of the substrate mounting portion 110 of the insulator 100 and stays there. Then, the printed circuit board 600 is mounted on the substrate mounting section 110. In this mounting operation, since the contact portion 210 of the contact 200 does not exist in the portion of the substrate mounting portion 110 where the printed circuit board 600 is mounted, without worrying about the contact 200,
The printed circuit board 600 may simply be mounted on the substrate mounting portion 110 such that one side of the printed circuit board is in contact with the side wall and the back surface of the terminal electrode forming surface is in contact with the bottom surface 111 (FIG. 2A,
(B)).

Next, with the printed circuit board 600 mounted, the plurality of contacts 200 are moved to a contact final deployment position (for example, a jig or the like) with one flat surface and not deformed (until the contact 200 stops). When pressed in (slide insertion), the contact portions 210 of the respective contacts 200 come into pressure contact with the corresponding terminal electrodes of the printed circuit board 600, and the printed circuit board 600 is held and fixed to the connector for board connection (FIG. 2C). reference).

No deformation occurs.

Each of the plurality of contacts 200 has a contact portion 210 as shown in each drawing.
It is needless to say that the sliding movement becomes smooth by making the portion which comes into pressure contact with the insulator 100 (upper surface 113) and the surface of the printed circuit board 600 into a rounded shape with the tip portion warped. . In this case, even if the foremost portion protrudes from the upper surface 113, it does not hinder the mounting of the printed circuit board 600. In addition, a step is provided in the upper surface 113 of the insulator 100 so that the contact 200 does not fall off. Further, the contact 200
A flexible board can be inserted between the connecting portion 220 and the linear portion of the holding portion 230 to connect to the circuit to be connected.
