- the end of the shield member (braid or the like) is covered with the shield shell 31, and the caulking ring 7 is placed thereon, and the caulking ring 7 is caulked to connect and fix the shield member (braid or the like). (See FIG. 18).
- the integrated housing 41 is integrally formed with the end portion 12 of the electric wire 11 and the terminal fitting 21 to integrally fix the end portion 12 of the electric wire 11 and the terminal fitting 21. Therefore, for the same reason as in the first embodiment, the integrated housing 41 performs an insulating function between parts and a holding function of the parts, and also performs a waterproof function of the electric wires 11 and the terminal fittings 21, thereby reducing the number of components. Therefore, the assembly work of the connector 1 is simple and the number of processes can be reduced. In addition, since the number of components can be reduced, the space for each component is reduced, and the connector 1 can be downsized.
- the integrated housing 41 is integrally formed with the end portion 12 of the electric wire 11 and the terminal fitting 21 and the shield shell 31 so as to integrally fix the shield shell 31 together with the end portion 12 of the electric wire 11 and the terminal fitting 21. Therefore, similarly to the first embodiment, the shield shell 31 functions as a rigid reinforcing member of the integrated housing 41.
- the integrated housing 41 can be formed of a material having low rigidity as compared with a general housing material, and the degree of freedom in material selection is increased.
- the integral housing 41 is formed of a material having a lower rigidity than that of a general housing material, whereby the integral housing 41 itself can be provided with the seal portion 46, which also reduces the number of components. become.
- a permanent magnet 48 is provided on the seal portion 46. Therefore, high waterproofness can be obtained by the adhesion force due to the compression deformation of the resin portion of the seal portion 46 and the attractive force due to the magnetic force of the permanent magnet 48. Further, even when the integrated housing 41 is formed of a material in which the durability of the synthetic resin itself is inferior, since the close contact is also caused by the magnetic force of the permanent magnet 48, the durability of the adhesion as the seal portion 46 can be maintained. Thereby, the freedom degree of the material selection of the integral housing 41 improves. Furthermore, since the seal portion 46 has a tapered shape, it is easily elastically deformed, has good follow-up to the unevenness of the close contact surface, and has excellent close contact properties, so that the waterproof property is improved.
- seal portion 46 there is one seal portion 46, but a plurality of seal portions 46 may be provided.
- FIG. 23 shows a connector 1 according to the sixth embodiment.
- the connector 1 according to the sixth embodiment includes the electric wire 11, the terminal fitting 21, the shield shell 31, and the integrated housing 41.
- the configuration of the integrated housing 41 is partially different from the first embodiment. To do.
- the inner housing 50 molded with a resin material different from that of the integrated housing 41 is provided inside the integrated housing 41.
- a resin material having a hardness higher than that of the integrated housing 41 is selected.
- a resin material having a lower hardness than the inner housing 50 is selected for the integrated housing 41.
- the inner housing 50 performs insulation between components by integrally forming the entire exposed conductor of the electric wire 11 from the end of the inner insulating layer of the electric wire 11 and the entire electric wire 11 side of the terminal fitting 21.
- the end 12 of the electric wire 11 and the terminal fitting 21 are fixed integrally.
- the integral housing 41 is molded integrally with the inner housing 50, the shield shell 31, and a part of the electric wire 11.
- the inner housing 50 has a function of insulating the parts and maintaining the strength between the electric wire 11 and the terminal fitting 21. For this reason, the choice of the resin material used for the integral housing 41 expands, and there exists an effect that material cost can be held down. Further, since a resin material having a hardness lower than that of the resin material used for the integrated housing 41 is used, the seal portion 46 can be brought into close contact with the inner wall of the mounting hole 5 on the mating side 3. The waterproof function of the attachment part to the side 3 can be further enhanced.
- FIG. 24 shows a connector 1 according to the seventh embodiment.
- the connector 1 according to the sixth embodiment includes the electric wire 11, the terminal fitting 21, the shield shell 31, and the integrated housing 41.
- the configuration of the integrated housing 41 is partially different from the first embodiment. To do.
- the front holder 51 made of another member is provided on the front surface of the integrated housing 41.
- the front holder 51 includes an insertion port 52 through which the terminal fitting 21 is inserted, is inserted from the end of the terminal fitting 21, and is fixed by being locked or press-fitted into the end of the front end cylindrical portion 34 of the shield shell 31. . With such a configuration, the front holder 51 can hold the terminal fitting 21 firmly.
- the front holder 51 is formed of an insulating resin material such as polybutylene terephthalate (PBT) or syndiotactic polystyrene (SPS), which is a hard material used for a general connector housing.
- PBT polybutylene terephthalate
- SPS syndiotactic polystyrene
- the mold used in the first embodiment can be dealt with by simply deleting the portion corresponding to the front holder 51. It can be easily modified.
- FIG. 25 shows a connector 1 according to the eighth embodiment.
- the connector 1 according to the eighth embodiment includes the electric wire 11, the terminal fitting 21, the shield shell 31, and the integrated housing 41.
- the configuration in the vicinity of the seal portion 46 of the integrated housing 41 is the first. This is partly different from the embodiment.
- the groove portion 53 is provided over the entire region in the circumferential direction of the housing before and after the seal portion 46 in the insertion direction of the connector 1 in the first embodiment.
- three groove portions 53 are provided before and after the two seal portions 46.
- FIG. 26A shows a terminal fitting 21 used in the ninth embodiment. That is, in the ninth embodiment, the configuration of the terminal fitting 21 is partially different from the first to eighth embodiments.
- the terminal fitting 21 includes a hole 23 provided in the vicinity of the center of the terminal fitting 21 and overhangs 24 provided on both side surfaces of the terminal fitting 21.
- the hole 23 is provided so as to penetrate the terminal fitting 21, but is not limited thereto, and may be a groove shape that does not penetrate the terminal fitting 21.
- the hole 23 is provided in a square shape.
