Abstract
A conductive terminal (1) used for an electrical socket comprises a retaining body (10) retained to a terminal hole (24) of the base of an electrical socket (2), a soldering portion (12) and a resilient arm (16) both extending from the retaining body. The retaining body is parallel to one lateral side of the base during insertion into the base. The resilient arm has a body portion (17) connected to one side (13) of the retaining body and a curved beam (18) conductively contacting with an upper printed circuit board. An angle (α) defined between the retaining body and the body portion of the resilient arm is an obtuse angle so that the curved beam extends substantively in a diagonal direction (W) of a corresponding terminal hole.
Claims18
A conductive terminal adapted for use in an electrical socket comprising:
- a retaining body adapted to be retained to an insulating base of the electrical socket;
- a soldering portion extending from a lower end of the retaining body adapted for soldering to a lower printed circuit board;
- and
- a resilient arm having a body portion extending from a side of the retaining body and a curved beam extending from a top end of the body portion and adapted for conductively contacting with an upper printed circuit board;
- wherein an angle is defined between the retaining body and the body portion of the resilient arm and is not a right angle.
An electrical socket for being electrically connected between two upper and lower circuit boards, comprising:
- a base defining a plurality of terminal holes;
- and
- a plurality of conductive terminals being simultaneously inserted into the terminal holes and each having a retaining body, a soldering portion for soldering to a lower circuit board, and a resilient arm for conductively contacting an upper circuit board and having a body portion extending from the retaining body;
- wherein an angle defined between the body portion and the retaining body is not a right angle.
An electrical socket for use with opposite upper and lower printed circuit boards sandwiching said socket therebetween, comprising:
- a base defining a plurality of terminals holes;
- a plurality of conductive terminals disposed in said terminals holes, respectively, each of said terminals including:
- a retaining body, for retaining the terminal to the base, defining a plane along either a longitudinal direction or a transverse direction of the base;
- a lower contact portion extending from a lower portion of the retaining body for contacting the lower printed circuit board;
- and
- an upper contact portion extending from an upper portion of the retaining body for contacting the upper printed circuit board;
- wherein
- an engagement portion of said upper contact portion, including the engagement end thereof, essentially extends in a direction at an angle which is not parallel to either said longitudinal direction or said transverse direction.
An LGA socket comprising:
- an insulative base defining a plurality of terminal holes therein;
- a plurality of terminals disposed in the corresponding holes, respectively, each of said terminals including:
- a planer retaining body;
- a surface mount solder portion extending from a lower edge of said retaining body for being seated upon a printed circuit board;
- a resilient arm including an upwardly extending planar body portion of which a lower portion is integrally connected to a side edge of said retaining body, and a curved beam generally horizontally extending from an upper edge of said planar body portion and toward said retaining body with a free end facing upwardly for engagement with a conductor of another printed circuit board seated upon said socket;
- wherein both said curved beam and said solder portion are located horizontally within a contour of said hole.
