FIXING MEMBER AND FIXING STRUCTURE

Abstract

The fixing member of the present invention can be mounted to a fixed member that is fixed to a printed circuit board and that is used for fixing the fixed member to the printed circuit board, the fixing member including: a mounting member main body fixed to the fixed member; male connector portions having at tip ends thereof lug portions that are engaged with an opening edge of an insertion opening in the printed circuit board when inserted into the inserting opening; and contact portions that contact with a soldering land formed at the printed circuit board and are joined to the soldering land by soldering when the lug portions are engaged with the opening edge, the contact portions being formed at the mounting portion main body and the male connector portions extend arm-shaped from the mounting portion main body or from the contact portions.

Claims

1. A fixing member that can be mounted to a fixed member that is fixed to a printed circuit board and that is used for fixing the fixed member to the printed circuit board, the fixing member comprising: a mounting member main body fixed to the fixed member;male connector portions having at tip ends thereof lug portions that are engaged with an opening edge of an insertion opening in the printed circuit board when inserted into the inserting opening; andcontact portions that contact with a soldering land formed at the printed circuit board and are joined to the soldering land by soldering when the lug portions are engaged with the opening edge,wherein the contact portions are formed at the mounting portion main body and the male connector portions extend arm-shaped from the mounting portion main body or from the contact portions.

2. The fixing member of claim 1, wherein the contact portions are formed at one end of the fixing member and the male connector portions are formed at another end of the fixing member main body so as to fold back toward the contact portions.

3. The fixing member of claim 1, wherein the contact portions are formed at one end of the fixing member and the male connector portions are formed at the contact portions and adjacent the fixing member main body.

4. The fixing member of claim 2, wherein the fixing member main body, the male connector portions, and the contact portions are formed integrally.

5. The fixing member of claim 3, wherein the fixing member main body, the male connector portions, and the contact portions are formed integrally.

6. The fixing member of claim 4, wherein the contact portions are formed by bending one end of the mounting member main body and the male connector portions are formed by bending another end of the mounting portion main body toward the contact portions.

7. The fixing member of claim 5, wherein the contact portions are formed by bending one end of the mounting member main body and the male connector portions extend arm-shaped from the contact portions and adjacent the mounting member main body.

8. A fixing structure comprising: the fixing member according to claim 1;a fixed member fixed to the fixing member main body provided at the fixing member; anda printed circuit board having an insertion opening and a soldering land, the male connector portions of the fixing member being inserted into the insertion opening thereof and contact faces of the fixing member being joined to the soldering land thereof by soldering to thereby fix the fixed member.

9. The fixing structure of claim 8, wherein the soldering land of the printed circuit board is a contact portion soldering land disposed around the opening andthe printed circuit board further includes a lug portion soldering land formed at a side at which the lug portions protrude, the lug portion soldering land being joined to the lug portions by soldering.
