Method of manufacturing electrical connection block
View Patent ↗An electric connection block is provided with a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar. The bus bar is provided with a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part. The electric connection block is manufactured by insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part, and bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part after the insert molding of the housing.
1. A manufacturing method of an electric connection block, the electric connection block including a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar, and the bus bar including a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part, the manufacturing method comprising:
insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part such that the before-bent standing terminal faces into an opening formed in the housing; and
bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part from the opening after the insert molding of the housing.
2. A manufacturing method of an electric connection block, the electric connection block including a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar, and the bus bar including a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part, the manufacturing method comprising:
insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part;
bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part after the insert molding of the housing;
molding the housing such that the before-bent standing terminal faces into an opening formed in the housing when insert molding of the housing; and
inserting a bending tool into the opening and bending the base end of the standing terminal to thereby erect the standing terminal after the insert molding of the housing.
3. The manufacturing method of the electric connection block according to claim 2 , the manufacturing method further comprising:
erecting a protection wall for protecting the standing terminal on a periphery of the opening of the housing.
4. The manufacturing method of the electric connection block according to claim 2 , the manufacturing method further comprising:
inserting a sub-housing having a cavity for insertion of a part connectable to the standing terminal into the opening of the housing so as to protect the standing terminal after the erecting of the standing terminal.
5. The manufacturing method of the electric connection block according to claim 3 , the manufacturing method further comprising:
inserting a sub-housing having a cavity for insertion of a part connectable to the standing terminals into the opening of the housing so as to protect the standing terminals after the erecting of the standing terminal.
6. The manufacturing method of the electric connection block according to claim 1 , wherein the standing terminal comprises a fork terminal having a pinching slit for pinching a blade-shaped terminal.
7. The manufacturing method of the electric connection block according to claim 1 , the manufacturing method further comprising:
providing a bridge portion on the bus bar in the press molding stage, the bridge portion holding a portion of the bus bar other than the main plate part by connecting the portion of the bus bar other than the main plate part to the main plate part before cut, and electrically disconnecting the portion of the bus bar other than the main plate part from the main plate part after cut; and
cutting the bridge portion when bending the base end of the standing terminal after the insert molding of the housing.
8. The manufacturing method of the electric connection block according to claim 2 , the manufacturing method further comprising:
providing a bridge portion on the bus bar in the press molding stage, the bridge portion holding a portion of the bus bar other than the main plate part by connecting the portion of the bus bar other than the main plate part to the main plate part before cut, and electrically disconnecting the portion of the bus bar other than the main plate part from the main plate part after cut; and
cutting the bridge portion when bending the base end of the standing terminal after the insert molding of the housing.
