Inventor: TAKEUCHI SHINOBU
IPC: H01R24/00
Filed: 2001-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a connector which can be easily manufactured, having a good connection state with a circuit board. SOLUTION: The connector is a CPU socket mounted to a circuit board 2, having terminals 5 arranged inside inner cases 4a, and solders 6 fixed to the terminals 5. A pair of stick-shaped pieces 12 having a first nail part 13 and a second nail part 14 are formed to connections of the terminals 5. When fixing the solder 6 to the connections 11, the solder 6 is caulked by bending the first nail parts 13 at the top end so that the first nail parts touch with each other. An inner through path 15 communicating upper side with lower side is formed to the connections 11. The solder 6 does not fall off from the terminal 5 because the solder is mounted to the inner case 4a by being caulked to the connections 11 of the terminal 5. Coplanarity of the top end of respective solders 6 is easily heightened because the length of the solder 6 protruded from the connections 11 can be adjusted at the caulking position of the solder 6.
