Description

  The present invention relates to a shielded connector used in an environment where liquids such as oil and water scatter.

  There is a molded connector as a shield connector for connecting a terminal-processed shielded wire to a device (for example, see Patent Document 1).

  Here, a method for assembling the shield connector 1 will be briefly described.

  First, the shield wire 41 is subjected to terminal treatment so that the conductor 42, the insulator 43, and the braided wire 44 are exposed by a predetermined length. The conductor 42 is inserted into the conductor insertion portion 12h of the terminal fitting 2, and the terminal fitting 2 and the conductor 42 are crimped and connected. The rubber mold 3 covers the corrugated portion 14 of the terminal fitting 2 to a part of the insulator 43 (procedure 1).

  The distal end side of the sheath 45 is inserted into the metal ferrule 6, and the braided wire 44 is folded back on the outer peripheral surface of the metal ferrule 6. The folded braided wire 44 is inserted into the conductive case 7, and the inserted braided wire 44 and the conductive case 7 are crimped and connected (procedure 2). Procedures 1 and 2 are in no particular order.

  The conductive case 7 is inserted into the rear end side of the metal housing 4, and the rear end side of the rubber mold 3 is inserted into the front end side of the metal housing 4.

  The front end side of the rubber mold 3 is inserted from the rear end of the resin case 5, and the engaging portion 18 of the resin case 5 is engaged with the concave groove 15 of the metal housing 4, thereby locking the resin case 5 to the metal housing 4. (Procedure 3).

  The wire seal 8 is attached to the sheath 45, and the O-ring 9 is attached to the attachment groove 19 of the metal housing 4. Finally, when the rear nut 10 is screwed into the metal housing 4 (procedure 4), the shield connector 1 is obtained. Procedures 3 and 4 are also in no particular order.

  The operation of the first embodiment will be described.

  The shield connector 1 is covered with a heat-resistant rubber mold 3 from the corrugated portion 14 which is the tip of the crimping portion 12 of the terminal fitting 2 to a part of the insulator 43, and the rubber mold 3 is covered with the metal housing 4 and the resin case 5. By being inserted, it is compressed radially inward.

  The crimping portion 12 of the terminal fitting 2 after crimping tends to vary in shape, but the shield connector 1 can absorb this variation by the elasticity of the rubber mold 3. The sealing effect between the resin cases 5 and between the rubber mold 3 and the metal housing 4 is very high. Therefore, it is possible to prevent liquid such as oil and water from entering the crimping portion 12 of the terminal fitting 2.

  Moreover, by forming the wave-like part 14 in the crimping part 12 of the terminal metal fitting 2, not only the displacement of the rubber mold 3 is prevented, but also the sealing effect between the terminal metal fitting 2 and the rubber mold 3 is further enhanced.

  Furthermore, since the rubber mold 3 has heat resistance, liquid such as oil and water can be prevented from entering the crimping portion 12 of the terminal fitting 2 in an atmosphere of high temperature (for example, 170 to 200 ° C.). In particular, when the rubber mold 3 is formed of silicone rubber or fluororubber, it has sufficient waterproof and oilproof properties even at an ambient temperature of about 250 ° C.

  Since a plurality of protrusions 3 f and 3 b are provided on the outer periphery of the rubber mold 3, adhesion between the resin case 5 and the metal housing 4 is enhanced, and between the rubber mold 3 and the resin case 5 and between the rubber mold 3 and the metal housing 4. The sealing effect is further enhanced.

  The resin case 5 can be easily attached to the rubber mold 3 and the metal housing 4 by the concave groove 15 provided in the metal housing 4 and the engaging portion 18 provided in the resin case 5, and displacement of the resin case 5 can be prevented. .

  Since the flange 7f sandwiched between the metal housing 4 and the rear nut 10 is provided at the rear end of the conductive case 7, the braided wire 44 is pressure-bonded to the conductive case 7, and then the rear nut 10 is screwed into the metal housing 4. Thereby, the braided wire 44 and the metal housing 4 can be reliably conducted.

  A heat-resistant O-ring 9 is attached to the metal housing 4, and a rear nut 10 is screwed into the metal housing 4 to compress the O-ring 9 radially inward, thereby increasing the sealing effect between the metal housing 4 and the rear nut 10. Moreover, it is possible to prevent liquids such as oil and water from entering the braided wire 44 in an atmosphere at a high temperature.

  By attaching a heat-resistant wire seal 8 to the sheath 45, screwing the rear nut 10 into the metal housing 4 and compressing the wire seal 8 radially inward, the sealing effect between the sheath 45 and the rear nut 10 is enhanced. It is possible to prevent liquids such as oil and water from entering the braided wire 44 in a high temperature atmosphere.

  Since a plurality of protrusions 8u and 8d are provided on the inner and outer circumferences of the wire seal 8, the adhesion between the sheath 45 and the rear nut 10 is enhanced, and the sealing effect between the sheath 45 and the wire seal 8 and between the wire seal 8 and the rear nut 10 is improved. More enhanced.

  After being assembled, the shield connector 1 is used by connecting the terminal fitting 2 to a terminal block of a device such as a motor on the load side, and attaching the housing mounting portion 16 to the housing of the device.

  Therefore, the shield connector 1 is excellent in waterproofness and oilproofness, and can supply power to the device through the conductor 42 while preventing liquid such as oil and water from entering the shielded electric wire 41 in a high atmosphere. In addition, the housing of the device and the braided wire 44 can be conducted and grounded.

  A second embodiment will be described.

  As shown in FIG. 2, the shield connector 21 is different from the shield connector 1 of FIG. 1 in that a resin mold 25 is used instead of the resin case 5 and a conductive case 27 is used instead of the conductive case 7. The metal housing 24 that does not use the O-ring 9 is used instead of the wire 4, and the wire seal 28 is used instead of the wire seal 8. Other configurations of the shield connector 21 are substantially the same as those of the shield connector 1.

  In the shield connector 1, the resin case 5 is locked to the metal housing 4 by the engaging portion 18. In the shielded connector 21, a substantially cylindrical resin mold 25 is formed and attached by molding a heat-resistant resin on the distal end side of the outer periphery of the rubber mold 3 and the distal end side of the outer periphery of the metal housing 24. The metal housing 24 and the resin mold 25 are integrated. As the resin, for example, a fluorine-based or silicone-based resin is used.

  In this case, the concave groove 15 of the metal housing 24 prevents the resin mold 25 from shifting. Therefore, instead of the concave grooves 15, knurls in which a large number of notches are formed vertically and horizontally or obliquely may be used.

  In the shield connector 21, a ring-shaped contact 27 a that swells radially outward is provided on the distal end side of the outer periphery of the conductive case 27 in order to connect the braided wire 44 and the metal housing 24. If the conductive case 27 is inserted into the metal housing 24 by the contact 27a, the contact 27a contacts the metal housing 24, so that the conductive case 27 and the metal housing 24 can be reliably conducted.

  Since the shield connector 21 does not use an O-ring, it extends to the rear end of the metal housing 24 in addition to the configuration of the wire seal 8 in FIG. 1, and the rear end of the metal housing 24 and the inner peripheral surface of the rear nut 30. A wire seal 28 sandwiched between the rear ends is used.

  The wire seal 28 increases the sealing effect between the sheath 45 and the rear nut 10 and between the metal housing 24 and the rear nut 30 without using an O-ring, and further, oil, water, etc. are applied to the braided wire 44 in a high temperature atmosphere. Can be prevented from entering. Other functions and effects of the shield connector 21 are the same as those of the shield connector 1.

It is a longitudinal cross-sectional view of the shield connector which shows the 1st Embodiment of this invention. It is a longitudinal cross-sectional view of the shield connector which shows the 2nd Embodiment of this invention.
