2. Description of the Related Art When electronic components are mounted on a substrate, especially on a printed circuit board, a soldering connection method is predominantly used to connect terminals of the electronic component to lands and through holes of the printed circuit board. However, this connection by soldering may cause contact failure of terminals due to scattering and penetration of flux, short circuit due to solder bridges, deformation and deterioration of members due to heat, etc.
Various improvement proposals have been made.

It has also been done to complete. Hereinafter, mounting by this connection will be described as press-fit mounting.

[0004] By the way, with the increase in the density of electronic devices, there is an increasing demand for multi-pin integrated circuits and connectors. For this reason, for example, when many connectors are mounted on a board, the number of boards that complete the connection by the press-fit mounting without using soldering for mounting these electronic components is increasing.

The board receiving jig 3 in which the relief grooves 3a are formed and arranged is fixed by screws 4 at a position corresponding to a connector mounting position on the board. Further, the base plate 2
An escape hole 5 for another component mounted on the substrate is formed through the base plate 2, and a substrate positioning pin for positioning the substrate when the substrate is placed on the substrate receiving jig 3. Two of the base plates 2 are fixed to the corners of one side of the base plate 2 upright.

To press-fit a multi-pin connector into a board using
The substrate positioning pins 6 are inserted into positioning holes formed in a substrate (not shown), and the substrate is placed on the substrate receiving jig 3. Next, the connector pins corresponding to the through holes formed on the board are temporarily inserted, and the connectors are pressed from above using a hydraulic press or the like to press-fit the connector pins into the through holes, whereby the connectors are respectively inserted into the board. Implemented. At this time, the connector pin does not escape into the escape groove 3a and the connector pin itself does not undergo physical deformation.

The dedicated mounting jig device 1 for each type of substrate includes a base plate 2, a substrate receiving jig 3, and positioning pins 3.
Are exclusively used for each type of board, the board receiving jig 3 and the board positioning pins cannot be diverted to another board on which the same connector is mounted, so that man-hours are required for design and manufacture. In addition, since it has to be prepared for each substrate, a large storage space is required and the management is complicated. In view of such problems, the present invention proposes an electronic component mounting jig device in which the substrate receiving jig 3 and the substrate positioning pins 6 can be diverted.

As shown in FIG. 2B, a dedicated base plate 8 for each board type is provided with a corresponding one of the plurality of multi-pin connectors mounted on a board corresponding to the base plate. A pair of positioning holes (hereinafter, referred to as substrate receiving jig positioning holes) 11a and 11b for positioning the jig 9.
Is provided. Then, the board receiving jig 9 corresponding to the type of the multi-pin connector is positioned and fixed on the dedicated base plate 8 for each board type, corresponding to the position where the multi-pin connector of the board is mounted.

The fixing of the substrate receiving jig 9 to the dedicated base plate 8 for each substrate type is performed by using a permanent magnet mounted on the substrate receiving jig 9 as described later. Is made of a magnetic material such as stainless steel. Further, positioning holes (hereinafter, referred to as substrate positioning jig positioning holes) 12, 12 for positioning the substrate positioning jigs 10, 10 are provided at two corners on one side of the dedicated base plate 8 for each substrate type. Is formed.

Next, as shown in FIG. 3A, the substrate receiving jig 9 has a rectangular parallelepiped base as a whole, and is pressed into a through hole of the substrate at the substrate receiving surface 9a. The escape grooves 13 of the connector pins are formed in the longitudinal direction corresponding to the connector pin pitch by the number corresponding to the connector pins or more. Further, a surface 9b opposite to the substrate receiving surface 9a on which the relief groove 13 is formed.

By the way, the shape of the connector mounted on the board differs depending on the type, but the absolute size of the outer shape is
Many are similar in terms of their functions. For this reason,
The board receiving jig 9 based on only the external dimensions of the connector.
However, if the design is the same, a difference in function will occur even with the same dimensions, and there is a high possibility that a work error will occur at the time of mounting. If there are few types of connectors mounted on the board, check the display field 8a (A in FIG. 2) printed on the dedicated base plate 8 for each board type by referring to the connector product symbol display field 16. However, if the number of types of connectors is increased, there is a possibility that the above-described confirmation alone may invite a work error.

Therefore, as shown in FIG. 3B, the positions at which the board receiving jig positioning pins 14, 14 (FIG. 3A) are provided differ depending on the type of connector, and the positions at which the positioning pins are provided are different.
