Abstract
An electrical connector used for connecting a circuit processing unit (CPU) with pins with a print circuit board (PCB) includes an insulating housing, a plurality of terminals received in the housing and a plurality of fusible members mechanically fixed into the housing. The housing includes a plurality of passageways and receiving cavities communicating with each other. Each of the terminals received in the corresponding passageway has a soldering portion. Each fusible member mechanically fixed into the corresponding receiving cavity has a through hole for receiving the soldering portion of the terminal. A gap is formed between the soldering portion and the fusible member when the soldering portion received in the through hole.
Claims18
An electrical connector for connecting a CPU (central processing unit) with a PCB (printed circuit board) comprising:
- an insulating housing having a plurality of passageways and receiving cavities communicating with each other;
- a plurality of terminals received in the corresponding passageways and each having a soldering portion;
- and
- a plurality of fusible members mechanically held into the corresponding receiving cavities and each having a through hole;
- wherein
- the soldering portion of the terminal is received in the through hole and apart from the fusible member.
An electrical connector comprising:
- an insulating housing defining a top face and a bottom face opposite to each other;
- a plurality of passageways extending between the top face and the bottom face;
- an encampment associated with each of the passageways at the bottom face, and including an extension crossing over a partition wall of the passageway to substantially enlarge the passageway;
- a plurality of terminals each having an elastic arm extending beyond the top face, a main portion disposed in the passageway, and a soldering portion extending beyond the bottom face;
- a plurality of fusible members each mechanically disposed in the encampment and secured by the extension of the encampment;
- and
- wherein a gap is formed between the soldering portion of the terminal and the fusible member.
An electrical connector comprising:
- an insulative housing defining opposite upper and lower surfaces with a plurality of passageways therethrough in a vertical direction;
- a plurality of contacts disclosed in the corresponding passageways, respectively, each of said contacts defining an upper contacting section located around the upper surface, and a lower soldering section exposed around the lower surface;
- a plurality of solder gripping devices unitarily formed on the lower surface corresponding to said soldering sections, respectively, and
- a plurality of solder masses located around the corresponding soldering sections and gripped by the corresponding solder gripping devices for retention, respectively, wherein
- the soldering section provides no substantial retention to the corresponding solder mass before said solder mass is fused upon a printed circuit board.
