Structure of bonding plastic part insert-molded with wiring board and method of bonding the same
View Patent ↗In insert-molding a wiring board, at either one of a surrounding of a holding hole of the wiring board provided at a first plastic part and a second plastic part opposed thereto, a hole side projected portion capable of being brought into contact with a bonding face of other thereof is provided, and the surrounding of the holding hole in the first plastic part and the second plastic part are bonded to each other by melting the hole side projected portion by applying ultrasonic wave to bonding portions of the two plastic parts.
1. A bonding structure of plastic parts, comprising:
a first plastic part comprising an insert-molded wiring board at least partially surrounded by plastic and at least one wiring board holding hole extending through the plastic that at least partially surrounds the wiring board, wherein the wiring board is connected to a connection terminal;
a second plastic part comprising a bonding face;
wherein excess plastic material selectively located in an area surrounding said at least one holding hole is bonded to the bonding face of the second plastic part.
2. The bonding structure according to claim 1 , wherein said bonding structure further comprises a third plastic part comprising an insert-molded wiring board, said third plastic part comprising at least one wiring board holding hole, and
wherein excess plastic material surrounding said at least one holding hole of said third plastic part and a bonding face of said first plastic part opposed to said at least one holding hole of said third plastic part are bonded to each other so that said third plastic part is stacked to said first plastic part.
3. The boding structure according to claim 1 , wherein an electric wire connected to the wiring board is further insert-molded to the first plastic part.
4. The bonding structure according to claim 1 , wherein said surrounding of said holding hole is ring-shaped.
5. A door latch component for a vehicle, comprising:
a door latch component comprising a plastic bonding member;
wherein the plastic bonding member comprises a bonding structure as defined in claim 1 .
6. The bonding structure according to claim 1 , wherein said plastic material selectively located in an area surrounding said holding hole is raised from a bonding face of the first plastic part.
7. A bonding structure of plastic parts, comprising:
a first plastic part comprising an insert-molded wiring board at least partially surrounded by plastic, wherein the wiring board is connected to a connection terminal; and
a second plastic part comprising a terminal introducing hole in which said connection terminal is introduced;
wherein excess plastic material selectively located in an area surrounding said connection terminal said terminal introducing hole are bonded to each other.
8. The bonding structure according to claim 7 , wherein said bonding structure further comprises a third plastic part comprising an insert-molded wiring board, said third plastic part comprising at least one wiring board holding hole, and
wherein excess plastic material surrounding said at least one holding hole of said third plastic part and a bonding face of said first plastic part opposed to said at least one holding hole of said third plastic part are bonded to each other so that said third plastic part is stacked to said first plastic part.
9. The bonding structure according to claim 7 , wherein said surrounding of said connection terminal is wedge-shaped.
10. A bonding structure of plastic parts, comprising:
a first plastic part comprising an insert-molded wiring board at least partially surrounded by plastic and at least one wiring board holding hole extending through the plastic that at least partially surrounds the wiring board, wherein the wiring board is connected to a connection terminal; and
a second plastic part comprising a bonding face and a terminal introducing hole in which said connection terminal is introduced;
wherein excess plastic material selectively located in an area surrounding said at least one holding hole is bonded to the bonding face of the second plastic part,
wherein excess plastic material selectively located in an area surrounding said connection terminal said terminal introducing hole are bonded to each other.
11. The bonding structure according to claim 10 , wherein said bonding structure further comprises a third plastic part comprising an insert-molded wiring board, said third plastic part comprising at least one wiring board holding hole, and
wherein excess plastic material surrounding said at least one holding hole of said third plastic part and a bonding face of said first plastic part opposed to said at least one holding hole of said third plastic part are bonded to each other so that said third plastic part is stacked to said first plastic part.
12. The bonding structure according to claim 10 , wherein said surrounding of said holding hole is ring-shaped.
13. The bonding structure according to claim 10 , wherein said surrounding of said connection terminal is wedge-shaped.
