Holding member, mounting structure in which holding member is mounted on electronic circuit board, and electronic component including holding member

A mounting structure comprising:

• an electronic circuit board that is provided with a through hole;
• a holding member that has legs inserted into the through hole and holds an electronic component on the electronic circuit board;
• and
• solder that fills the through hole in a state in which the leg sections are inserted thereinto so as to secure the holding member to the electronic circuit board,
• wherein the holding member comprises:
• a plate-shaped base that is fixed to the electronic component;
• a first leg extending from the base, inserted into the through hole, and having a catch, the catch projecting laterally and outwardly with respect to an inserting direction in which the first leg is inserted into the through hole and being secured with an edge of the through hole after the first leg is inserted;
• and
• a second leg extending from the base, and inserted into the through hole together with the first leg section;
• the second leg being elastically deformed by coming into contact with an inner surface of the through hole and pressing the first leg toward an opposite side inner surface of the through hole, so that the second leg elastically holds the catch in a state in which the catch is secured with the edge of the through hole after the second leg is inserted.

An electronic component that is held on an electronic circuit board provided with a through hole, comprising:

• a holding member that has leg sections inserted into the through hole and holds the electronic component on the electronic circuit board,
• wherein the holding member comprises:
• a plate-shaped base that is fixed to the electronic component;
• a first leg that extends from the base, is inserted into the through hole, and has a catch, the catch projecting laterally and outwardly with respect to an inserting direction in which the first leg is inserted into the through hole and being secured with an edge of the through hole after the first leg is inserted;
• and
• a second leg that extends from the base, is inserted into the through hole together with the first leg section, the second leg is elastically deformed by coming into contact with an inner surface of the through hole and presses the first leg toward an opposite side inner surface of the through hole, so that the second leg elastically holds the catch in a state in which the catch is secured with the edge of the through hole after the second leg is inserted.
