Abstract

A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part for sealing the pair of conductive members. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the sealing step, the conductive members are sealed with a resin injected into a die while a force is applied by the resin to the individual conductive members in directions to approach each other in a facing orientation of the pair of conductive members.

First claim

What is claimed is:

1. A method for producing a conductive member module having a pair of conductive members formed in a plate shape and facing each other, and a sealing part for sealing the pair of conductive members, the method comprising performing:
an accommodation step of accommodating the pair of conductive members in a molding die in a state of being separated from each other,
a sealing step of injecting a fluid resin into the die to seal the pair of conductive members, and
an extraction step of extracting the conductive member module from the die;
wherein:
in the sealing step, the conductive members are sealed while the individual conductive members, to which a force is applied by the resin injected into the die in directions to approach each other in a facing orientation of the pair of conductive members, are supported by support members from inside in the facing orientation;
the conductive members are each provided with through holes penetrating in the facing orientation, and in the sealing step, the pair of conductive members are sealed in a state in which the support members inserted into the through holes support the individual conductive members from inside in the facing orientation;
in the sealing step, the conductive members are sealed with the resin injected into the die while portions that are not supported by the support members in the conductive members are curved inward in the facing orientation to form a curved portion in each of the conductive members; and
a distance between the pair of conductive members at the curved portion of each of the conductive members is less than a distance between the pair of conductive members at all other portions of the pair of conductive members.

2. The method for producing a conductive member module according to claim 1 , wherein in the sealing step, outer spaces formed between the individual conductive members and the die in the facing orientation are completely filled with the resin earlier than a central space formed between the pair of conductive members.

3. The method for producing a conductive member module according to claim 2 , wherein each of the outer spaces has a longer length in the facing orientation than that of the central space.

4. The method for producing a conductive member module according to claim 1 , wherein in the sealing step, the resin is injected into the die in a direction orthogonal to the facing orientation.

5. The method for producing a conductive member module according to claim 1 , wherein the support members are formed separately from the die.

6. The method for producing a conductive member module according to claim 5 , wherein the support members also serve as release pins for releasing the conductive member module from the die in the extraction step.

7. The method for producing a conductive member module according to claim 1 , wherein in the sealing step, the conductive members are sealed while connection terminals of the conductive members are sandwiched by the die on split surfaces of the die.
