Electrical connector for circuit boards
An electrical connector for circuit boards whose multiple terminals include signal terminals 40 and power supply terminals 50 , said power supply terminals 50 having retained portions 52 retained in place by the lateral walls 21 of the housing 20 , and said retained portions 52 being retained in place via press-fitting by the lateral walls 21 at both lateral edges in the terminal-width direction perpendicular to the through-thickness direction of said retained portions 52 , wherein the lateral walls 21 have stepped engaged portions 21 C in locations corresponding to the retained portions 52 of the power supply terminals 50 , and the retained portions, 52 , of the power supply terminals 50 have engaging portions 52 B capable of engaging the engaged portions 21 C in the heightwise direction of the connector.
1. An electrical connector for circuit boards disposed on a mounting face of a circuit board, said electrical connector for circuit boards having multiple sheet metal terminals arranged in a single array direction parallel to the mounting face and
a housing retaining said multiple terminals in place in array form,
the housing having lateral walls rising in a heightwise direction of the connector perpendicular to the mounting face while extending in an array direction,
the multiple terminals including signal terminals and power supply terminals,
said power supply terminals having retained portions retained in place by the lateral walls, and
said retained portions being retained in place via press-fitting by the lateral walls at both lateral edges in a terminal-width direction perpendicular to a through-thickness direction of said retained portions, wherein
the lateral walls have stepped engaged portions in locations corresponding to the retained portions of the power supply terminals, and
the retained portions of the power supply terminals have engaging portions capable of engaging the engaged portions in the heightwise direction of the connector;
wherein the power supply terminals are curved in shape in the through-thickness direction and are retained in place by said lateral walls such that the through-thickness direction of the retained portions coincides with a wall-thickness direction of the lateral walls of the housing.
2. The electrical connector for circuit boards according to claim 1 , wherein the engaging portions are formed as resilient strips cut and raised from a major face of the retained portions.
3. The electrical connector for circuit boards according to claim 1 , wherein the multiple retained portions are formed within the range of said retained portions in the terminal-width direction.
4. The electrical connector for circuit boards according to claim 1 , wherein
the terminals have formed therein a connecting portion intended for connecting to the mounting face of a circuit board at one end in the longitudinal direction of said terminals and a contact portion intended for contact with a counterpart connector element at the other end,
the connecting portions and the contact portions are located differently in the wall-thickness direction of the lateral walls of the housing, and
the connecting portions of the power supply terminals are located closer to the contact portions of said signal terminals in the wall-thickness direction of the lateral walls than the connecting portions of the signal terminals.
5. An electrical connector for circuit boards disposed on a mounting face of a circuit board, said electrical connector for circuit boards having multiple sheet metal terminals arranged in a single array direction parallel to the mounting face and
a housing retaining said multiple terminals in place in array form,
the housing having lateral walls rising in a heightwise direction of the connector perpendicular to the mounting face while extending in an array direction,
the multiple terminals including signal terminals and power supply terminals,
said power supply terminals having retained portions retained in place by the lateral walls, and
said retained portions being retained in place via press-fitting by the lateral walls at both lateral edges in a terminal-width direction perpendicular to a through-thickness direction of said retained portions, wherein
the lateral walls have stepped engaged portions in locations corresponding to the retained portions of the power supply terminals, and
the retained portions of the power supply terminals have engaging portions capable of engaging the engaged portions in the heightwise direction of the connector;
wherein
the terminals have formed therein a connecting portion intended for connecting to the mounting face of a circuit board at one end in the longitudinal direction of said terminals and a contact portion intended for contact with a counterpart connector element at the other end,
the connecting portions and the contact portions are located differently in a wall-thickness direction of the lateral walls of the housing, and
the connecting portions of the power supply terminals are located closer to the contact portions of said signal terminals in the wall-thickness direction of the lateral walls than the connecting portions of the signal terminals.
6. The electrical connector for circuit boards according to claim 5 , wherein the engaging portions are formed as resilient strips cut and raised from a major face of the retained portions.
7. The electrical connector for circuit boards according to claim 5 , wherein the multiple retained portions are formed within the range of said retained portions in the terminal-width direction.
