請求項１に記載の発明では、回路基板の実装面に半田付けされる半田付け要素が、複数のコンタクトのみで構成される。このため、特許文献１で用いられる取付釘が不要となり、構造を簡素化することができる。また、各コンタクトにおいて、被固定部から延びる一対のリード部の先端部が、実装面において挿入方向に関して貫通孔の両側で半田付けされる。このため、回路基板に対して高い取付強度を達成することができる。   According to the first aspect of the present invention, the soldering element to be soldered to the mounting surface of the circuit board is composed of only a plurality of contacts.

請求項４に記載の発明では、回路基板の実装面に半田付けされる半田付け要素が、複数のコンタクトのみで構成されるので、構造を簡素化することができる。また、複数のコンタクトが、挿入方向と直交する幅方向に交互に配置された第１コンタクト及び第２コンタクトを含み、また、第１コンタクトの第１リード部の先端部と第２コンタクトの第２リード部の先端部とが、実装面において挿入方向に関して貫通孔の両側に互い違いに半田付けされる。このため、回路基板に対して高い取付強度を達成することができる。   In the invention according to claim 4, since the soldering element to be soldered to the mounting surface of the circuit board is constituted by only a plurality of contacts, the structure can be simplified. The plurality of contacts include first contacts and second contacts that are alternately arranged in the width direction orthogonal to the insertion direction, and the tip of the first lead portion of the first contact and the second contact of the second contact. The leading end portion of the lead portion is soldered alternately on both sides of the through-hole in the mounting surface in the insertion direction. Therefore, high attachment strength to the circuit board can be achieved.

請求項５に記載の発明では、抜脱規制突起の挿入方向側にもコンタクトが配置される。このため、スペースの有効利用を図り且つ取付強度を向上することができる。   According to the fifth aspect of the invention, the contacts are also arranged on the insertion direction side of the withdrawal restricting protrusion. Therefore, the space can be effectively used and the mounting strength can be improved.
