A connector includes a plurality of metal terminal fittings connected to terminals of electric wires, a plurality of molded housings molded to connection parts of the electric wires and the metal terminal fittings to cover the connection parts, and an overmolded housing which accommodates and holds the plurality of molded housings. The plurality of molded housings are molded in a structure integrated by carrier portions that connect the adjacent molded housings to each other and are collectively integrated into the overmolded housing. The carrier portions have cross-section dimensions set to be smaller than those of the molded housing and have flexibility. An arrangement pitch between the adjacent molded housings are adjusted when the plurality of molded housings are collectively integrated into the overmolded housing.
1. An electrical connector comprising:
a plurality of metal terminal fittings connected to electric wires;
a plurality of molded housings molded to connection parts of the electric wires and the metal terminal fittings to cover the connection parts, the plurality of molded housings comprising:
first molded housings molded into a predetermined shape, and
second molded housings molded into a predetermined shape; and
an overmolded housing which accommodates and holds the plurality of molded housings,
wherein the plurality of molded housings are molded in a structure integrated by first and second carrier portions that connect the adjacent molded housings to each other and are collectively integrated into the overmolded housing,
wherein the first and second carrier portions have cross-section dimensions set to be smaller than cross-section dimensions of the molded housing and have flexibility,
wherein the first carrier portions have cross-section dimensions set to be different than cross-section dimensions of the second carrier portions,
wherein the plurality of molded housings are integrally formed in an arrangement structure in which first molded housings are disposed on both outer sides of adjacent second molded housings, and
wherein an arrangement pitch between the adjacent molded housings is adjusted when the plurality of molded housings are collectively integrated into the overmolded housing.
2. The connector according to claim 1 ,
wherein cross-section dimensions of the first and second carrier portions in a direction orthogonal to a direction in which the molded housings are lined up are set to dimensions that are at least 1/2 or less of cross-section dimensions of the molded housings in the same direction.
3. The connector according to claim 1 ,
wherein the first molded housings are molded into the predetermined shape by first housing cavities into which a resin material is directly injected from a resin injection gate of a mold and the second molded housings are molded into the predetermined shape by second housing cavities which are disposed adjacent to the first housing cavities, and
wherein the first carrier portions are molded by first carrier cavities that cause the first housing cavities and the second housing cavities to communicate with each other so as to cause the resin material injected into the first housing cavities to flow into the second housing cavities, thereby connecting the first molded housings and the second molded housings, and the second carrier portions are molded by second carrier cavities that cause the adjacent second housing cavities to communicate with each other, thereby connecting the adjacent second housing cavities.
4. The connector according to claim 1 ,
wherein a cross-sectional area of the second carrier portions is set to be smaller than a cross-sectional area of the first carrier portions.
5. An electrical connector comprising:
a plurality of metal terminal fittings connected to electric wires; and
a plurality of molded housings molded to connection parts of the electric wires and the metal terminal fittings to cover the connection parts, wherein the plurality of molded housings comprises first molded housings molded into a predetermined shape and second molded housings molded into a predetermined shape;
wherein the plurality of molded housings are arranged such that at least one first molded housing is disposed on both outer sides of adjacent second molded housings,
wherein first and second carrier portions connect adjacent molded housings to each other, wherein the first carrier portions connect the at least one first molded housing to an adjacent second molded housing of the pair of adjacent second molded housings, wherein the second carrier portions connect the pair of adjacent second molded housings,
wherein the first carrier portions have cross-section dimensions set to be different than cross-section dimensions of the second carrier portions.
6. The connector according to claim 5 ,
wherein a cross-sectional area of the second carrier portions is set to be smaller than a cross-sectional area of the first carrier portions.
