Electrical connector and method of producing the same
View Patent ↗An electrical connector comprises a housing and a terminal held by the housing. The terminal is provided with a first surface exposed form the housing and a second surface contacted with the housing. The first surface is plated, and the second surface is not plated.
1. An electrical connector produced by the steps of:
bending a flat portion of a terminal member in a thickness direction thereof, said terminal member being formed of a metal plate and including a carrier portion and the flat portion connected to the carrier portion to form
a terminal portion including a contact portion at one end portion thereof for contacting with a mating terminal of a mating connector, a connection portion at the other end portion thereof for connecting to a circuit board, and a retaining portion at a middle portion thereof to be retained in the housing;
molding the housing integrally with the terminal portion so that one surface of the contact portion is exposed from the housing and the other surface of the contact portion contacts with the housing, said connection portion protruding from the housing and having a whole surface exposed from the housing, said retaining portion contacting with the housing to be directly retained in the housing;
plating the terminal portion after the housing is integrally molded with the terminal portion in a state that the terminal portion is connected to the carrier portion; and
cutting the terminal portion from the carrier portion to obtain the electrical connector.
2. The electrical connector according to claim 1 , wherein said terminal portion further includes an introduction portion with a curved portion.
3. The electrical connector according to claim 1 , wherein said housing further includes a depressed portion for receiving a mating connector, said connection portion of the terminal portion extending outside the depressed portion.
4. The electrical connector according to claim 1 , wherein said housing further includes a depressed portion for receiving a mating connector, said contact portion of the terminal portion being disposed inside the depressed portion.
5. A method of producing an electrical connector, comprising the steps of:
bending a thin flat metal band of a terminal member formed of a metal plate, having a carrier portion and the thin flat metal band connected to the carrier portion in a plate thickness direction thereof to form a terminal portion having a contact portion at one end portion thereof for contacting with a mating terminal of a mating connector, a connection portion at the other end portion thereof for connecting to a circuit board, and a retaining portion at a middle portion thereof to be retained with a housing;
integrating the terminal portion with the housing so that one surface of the contact portion is exposed from the housing, the other surface of the contact portion contacts with the housing, the connection portion protrudes from the housing, a whole surface of the connection portion is exposed from the housing, and the retaining portion contacts with the housing and is directly retained with the housing;
plating the terminal portion after the terminal portion is integrated with the housing in a state that the terminal portion is connected to the carrier portion; and
cutting the terminal portion from the carrier portion.
