Electrical connector for circuit boards and method of manufacture thereof
Electrical connector for circuit boards provided with terminals having connecting portions configured to be connected to a circuit board at one end in the longitudinal direction of said terminals and contact portions configured to be placed in contact with a counterpart connector component at the other end, and a housing holding a plurality of said terminals in place in array form. Said housing having disposed therein the contact portions of the terminals, and formed such that it is divided into a receiving-side housing, which accommodates the contact portions and receives a counterpart connector component such that it is placed in contact with the contact portions, and a board-side housing, which holds the terminals in place in sections more proximal to the connecting portions than to the contact portions and which is mounted to a circuit board, and the receiving-side housing and the board-side housing are molded as a single unit.
1. An electrical connector for circuit boards comprising:
terminals having formed therein connecting portions configured to be connected to a circuit board at one end in the longitudinal direction of said terminals and contact portions configured to be placed in contact with a counterpart connector component at the other end, and
a housing holding a plurality of said terminals in place in array form, said housing having disposed therein the contact portions of the above-mentioned terminals, wherein:
the housing is formed such that it is divided into a receiving-side housing, which accommodates the contact portions of the terminals and receives a counterpart connector component such that said counterpart connector component is placed in contact with the contact portions, and a board-side housing formed separately from the receiving-side housing, which holds the terminals in place in sections more proximal to the connecting portions than to the above-mentioned contact portions and which is mounted to a circuit board, and
the receiving-side housing and the board-side housing are molded as a single unit from an injection molding to mold the receiving side housing and an integral molding on the board-side housing with the receiving-side housing.
2. A method of manufacture of an electrical connector for circuit boards comprising terminals having formed therein connecting portions configured to be connected to a circuit board at one end in the longitudinal direction of said terminals and contact portions configured to be placed in contact with a counterpart connector component at the other end, and a housing holding a plurality of said terminals in place in array form, said housing having disposed therein the contact portions of the above-mentioned terminals, the method comprising:
after molding the receiving-side housing, which receives the counterpart connector component, while the contact portions of the terminals are accommodated in said receiving-side housing, forming the board-side housing separately from the receiving-side housing, which holds the above-mentioned terminals in place in sections more proximal to the connecting portions than to the above-mentioned contact portions and which is mounted to a circuit board by conducting integral molding with the terminals and the receiving-side housing, such that the receiving-side housing and the board-side housing form an integrated housing.
3. The method of manufacture of an electrical connector for circuit boards according to claim 2 , further comprising, after placing the contact portions of the terminals in the receiving-side housing, bending the protruding sections of the terminals protruding from said receiving-side housing at arbitrary locations in the direction of protrusion, thereby forming connecting portions configured to be connected to the circuit board and,
forming the board-side housing, whose height dimension corresponds to the length of the protruding sections between the locations of protrusion from the receiving-side housing to the locations of the bend, via integral molding of the protruding sections of the terminals and the receiving-side housing.
4. The method of manufacture of an electrical connector for circuit boards according to claim 2 , further comprising, when molding the receiving-side housing, said receiving-side housing is molded integrally with anchor fittings configured for mounting to a circuit board and,
after the integral molding, forming anchoring portions configured for connecting to a circuit board by bending the protruding sections of the anchor fittings protruding from the receiving-side housing at arbitrary locations in the direction of protrusion and,
forming the board-side housing, whose height dimension corresponds to the length of the protruding sections between the locations of protrusion from the receiving-side housing to the locations of the bend, via integral molding of the protruding sections of the anchor fittings and the receiving-side housing.
