Connector

A connector to be mounted to a side surface of a substrate, including a plurality of contacts each having at least one contact portion adapted to contact a connecting object, a housing for arranging and holding said contacts and having a fitting opening into which said connecting object is inserted, and a pivoting member causing said contacts to be elastically deformed and pressed against said connecting object,

• wherein said connector comprises:
• said contacts each including a first piece having the contact portion at one end adapted to contact said connecting object, a pressure receiving portion at another end adapted to be pressed by said pivoting member, and a projection inwardly extending from the tip of said pressure receiving portion;
• a second piece having a further contact portion at one end, a connection portion at another end to be connected to the substrate, and a fulcrum portion between said further contact portion and said connection portion;
• and an elastic portion for connecting said first piece and said fulcrum portion, said contact portion, said elastic portion, said fulcrum portion and said connection portion being arranged in a form of a crank,
• said housing being provided at both longitudinal ends with extension walls for holding fixtures for fixing said housing of said connector against said substrate so as to reduce overall height, and said housing being formed with slits corresponding to anchoring portions of said housing and located between each said extension wall and a bearing for said pivoting member, said slits extending parallel to said contacts in a lengthwise direction and extending the a depth of the entire housing, and said slits providing elasticity for facilitating engagement of locking portions of said pivoting member with said anchoring portions of said housing, and
• said housing including a ceiling portion for covering said contact portions of said contacts, said ceiling portion being provided with protection wall ends at said fitting opening for preventing said ceiling portion from being deformed and said contacts from being disconnected from a connecting object when said connecting object is subjected to an upward force, said protection wall ends not being chamfered or inclined, and
• said pivoting member including an actuating portion for pivotally moving said pivoting member, urging portions continuously arranged in a longitudinal direction of said pivoting member, and anchoring holes independent from one another for receiving therein said pressure receiving portions and adapted to engage said projections, respectively, said pivoting member being mounted on said housing so that said urging portions are pivotally moved between said connection portions and said pressure receiving portions of said contacts, and a rotation axis of said urging portions is moved with a pivotal movement to achieve a compact rotation, and
• wherein said substrate is provided with a notch at said side surface, and said connector is connected onto said substrate in a manner that said connector is accommodated in said notch of said substrate so as to reduce a combined height of said connector and said substrate.
