Abstract:
A multipolar connector is provided. It is possible to prevent deformation of a particular pin-shaped terminal of plural pin-shaped terminals arranged in a line in a direction perpendicular to a connection direction of the multipolar connector, and also possible to prevent positional displacements of the particular pin-shaped terminal and other pin-shaped terminals. The multipolar connector (101) includes plural pin-shaped terminals (110) arranged in a line in a direction (arrow X direction) perpendicular to a connection direction (arrow Y direction) of the multipolar connector to extend in the connection direction, and a hold member (120) configured to extend in the direction perpendicular to the connection direction and hold the plural pin-shaped terminals (110) at a predefined pitch. A protection section (121) to protect a particular pin-shaped terminal (110) of the plural pin-shaped terminals (110) is provided at a part of the hold member (120) to extend from the hold member (120) to protrude in the connection direction of the particular pin-shaped terminal (110) to be protected and cover around the particular pin-shaped terminal (110).
