Printed circuit board-connecting connector with adjustable connections

A connector, comprising:

• a connector housing;
• at least one receiving chamber formed within the connector housing;
• at least one connection terminal including a contact portion which is insertable in the at least one receiving chamber of the connector housing, and a distal end portion which is electrically connectable to a conductive circuit pattern formed on a printed circuit board;
• and
• a spacer block fittable to the connector housing, the spacer block having a pair of upper and lower passage windows, which are disposed correspondingly to the at least one receiving chamber of the connector housing and symmetrically with respect to a center axis of the contact portion of the at least one connection terminal received in the at least one receiving chamber,
• wherein the distal end portion of the at least one connection terminal is passable through and retainable in the upper passage window when the contact portion of the at least one connection terminal is inserted in the at least one receiving chamber in a first position and the spacer block is fitted to the connector housing, and is passable through and retainable in the lower passage window when the contact portion is rotated on the center axis to a second position and is inserted in the at least one receiving chamber and the spacer block is fitted to the connector housing.
