Description

Technical Field

[0001] This invention relates to a plug-in connector, and more particularly to a connector with a shielded conductive structure. Background Technology

[0002] Most commercially available rear-mounted shielded connectors use either a metal ring for hard conduction or a spring contact method, among which:

[0003] When using a metal ring structure, the braid on the conductor is wrapped around a rigid metal ring 8, and then the metal ring is held in place by a clamping ring 9 to make it contact the sleeve 7. This operation is not easy to perform, and a long braid will be scattered between the metal ring and the clamping ring, which poses a risk of short circuit.

[0004] When using a spring structure, the spring is folded into a circular shape and fixed within the space formed by the clamping ring and the sleeve. During wire assembly, the circumferential deformation of the spring causes it to contact the wire braided layer. Due to the limited deformation of the spring's outer diameter, wires with larger outer diameters are difficult to assemble, while the spring cannot effectively contact the wire shielding layer for smaller diameter wires. Therefore, this mechanism is suitable for a limited range of wire diameters. Summary of the Invention

[0005] To overcome the above-mentioned defects, the present invention provides a connector with a shielded conductive structure. This connector is applicable to a wide range of wire diameters, is easy to install, and can achieve 360° shielding against external interference signals during signal transmission.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A connector with a shielded conductive structure includes a metal sleeve, conductive elastic claws, and an electrical connector.

The conductive elastic claws are fixedly installed on the inner side of one end of the metal sleeve and electrically connected to the metal sleeve. The other end of the conductive elastic claws can elastically clamp the outer surface of the braided layer of the cable inserted into the hollow structure of the metal sleeve. The electrical connector includes an insulating body, a conductive connecting sleeve, and a conductor.

[0028] Example: A connector with a shielded conductive structure includes a metal sleeve 1, conductive elastic claws 2, and an electrical connector 5. The metal sleeve 1 has a hollow structure inside for a cable 6 to pass through. The conductive elastic claws 2 are fixedly installed on the inner side of one end of the metal sleeve 1. One end of the conductive elastic claws 2 is electrically connected to the metal sleeve 1, and the other end of the conductive elastic claws 2 can elastically clamp the outer surface of the braided layer 62 of the cable inserted into the hollow structure of the metal sleeve 1. The electrical connector 5 includes an insulating body 53, a conductive connecting sleeve 52, and a conductor 51. The conductive connecting sleeve 52 is axially stopped and installed on the outside of the insulating body 53. The conductive connecting sleeve 52 can be fixedly connected to the other end of the metal sleeve 1 and electrically conductive. The insulating body 53 has a plug hole that is directly opposite to the inner conductor of the cable 6. The conductor 51 is fixedly installed in the plug hole. The end conductor 61 of the cable inserted from one end of the metal sleeve 1 can be inserted into the inner side of the plug hole of the insulating body 53 and make electrical contact with the conductor 51.

[0029] When assembling cable 6, cable 6 is inserted through one end of metal sleeve 1. For ease of installation, an extra section of cable 6 is inserted. After the conductor of cable 6 connects to the conductor 51 of electrical connector 5, electrical connector 5 is connected to the other end of metal sleeve 1 and fixed in position. At this time, the extra section of cable 6 is withdrawn from one end of metal sleeve 1. After it is completely withdrawn, the braided layer of cable 6 is tightly clamped and connected to the conductive elastic clamp 2. At this time, the braided layer of cable 6 and electrical connector 5 form a series circuit through conductive elastic clamp 2 and metal sleeve 1. When used with connectors, the shielding structure of this invention achieves shielding and conduction of the entire circuit, thereby achieving 360° shielding against external interference signals. The conductive elastic clamp 2 clamps and conducts the braided layer of cable 6 through the elastic relative opening and closing of the clamps, which can be used for a wider range of cable diameters. Moreover, the structure of this application is simpler, the connection of cable 6 is more convenient, the signal transmission is more stable, and the shielding effect is better.

[0030] The conductive elastic gripper 2 includes a fixing ring 23 and elastic cantilever grippers 21. At least two elastic cantilever grippers 21 are fixedly mounted on the fixing ring 23 at even intervals. The free ends of the elastic cantilever grippers 21 can generate elastic movement along the radial direction of the metal sleeve 1. The braided layer of the cable 6 can be tightly clamped between the free ends of each elastic cantilever gripper 21. One end of the metal sleeve 1 forms a countersunk through-hole structure with an increased opening size. The fixing ring 23 of the conductive elastic gripper 2 is inserted into the countersunk through-hole structure at one end of the metal sleeve 1. An annular insulating wire harness collar 3 is also provided. One end of the insulating wire harness collar 3 forms a cable 6 inlet for the cable 6 to enter. The other end of the insulating wire harness collar 3 can be fixedly inserted into the inner side of one end of the metal sleeve 1. The fixing ring 23 of the conductive elastic gripper 2 is tightly clamped between the other end of the insulating wire harness collar 3 and the stepped surface of the countersunk through-hole structure at one end of the metal sleeve 1.

[0031] The conductive elastic clamp 2's fixing ring 23 is clamped and positioned by the insulating cable tie 3 and one end of the metal sleeve 1, thus achieving the positioning and installation of the conductive elastic clamp 2 within the metal sleeve 1. The elastic cantilever clamp 21 of the conductive elastic clamp 2 achieves the clamping of the braided layer of the cable 6 through elastic deformation. The conductive elastic clamp 2's elastic cantilever clamp 21 is preferably three, four or more, to achieve stable clamping of the braided layer of the cable 6.

[0032] The conductive elastic gripper 2 has an elastic cantilever gripper 21 that is integrally formed on the side wall of the fixing ring 23 by bending. The free end of the elastic cantilever gripper 21 is closer to the axis of the metal sleeve 1 than the root. The free end of the elastic cantilever gripper 21 has an inclined guide bend that points away from the axis of the metal sleeve 1. The end of the elastic cantilever gripper 21 has a raised edge structure to prevent interference of the braided layer of the cable 6 when it expands and contracts between the elastic cantilever grippers 21.

The fixing ring 23 of the conductive elastic gripper 2 is inserted into the inner side of the other end of the insulating wire harness collar 3, and the clamping pieces 22 on the fixing ring 23 are tightly clamped between the stepped surface of the countersunk through hole structure at the other end of the insulating wire harness collar 3 and one end of the metal sleeve 1. The other end of the insulating wire harness collar 3 preferably forms a countersunk through hole structure with an increased opening size. The fixing ring 23 of the conductive elastic gripper 2 is inserted into the countersunk at the other end of the insulating wire harness collar 3, which facilitates radial limiting of the fixing ring 23.

[0034] The structure in which the other end of the insulating wire harness collar 3 can be fixedly inserted into the inner side of one end of the metal sleeve 1 is as follows: a sealing ring is fixedly installed on the outer side of the other end of the insulating wire harness collar 3, the other end of the insulating wire harness collar 3 is inserted into the inner side of one end of the metal sleeve 1, and the sealing ring on the outer side of the other end of the insulating wire harness collar 3 is tightly against the inner wall of one end of the metal sleeve 1.

The other end of the tightening nut sleeve 4 is movably threaded to one end of the metal sleeve 1, and the end face of one end of the insulating wire harness collar 3 is tightly against the stepped surface of the inner two ends of the tightening nut sleeve 4.

[0035] This structure enables a tight connection between the insulating wire harness collar 3 and the metal sleeve 1, preventing dust, oil, and other contaminants from entering and ensuring stable signal transmission. The stepped surfaces at both ends of the inner side of the clamping nut sleeve 4 are tapered slopes, which achieve stable clamping and positioning of the insulating wire harness collar 3.

[0036] The inner side of one end of the insulating cable sling 3 is also fitted with a cable sling that matches the outer diameter of the portion of the cable 6 covered by the outer sheath 63. The cable sling is used to bundle cables 6 of different specifications and prevent the cables 6 from shaking and wearing inside the insulating cable sling 3.

This structure enables the metal sleeve 1 and the insulating conveying collar to be positioned in the circumferential direction, so that the insulating wire harness 3 and the metal sleeve 1 form a stable integral structure.

[0038] The conductive connecting sleeve 52 of the electrical connector 5 is a metal nut sleeve with an inner diameter at one end larger than that at the other end. One end of the metal nut sleeve is threaded to the outer side of the other end of the metal sleeve 1. One end of the insulating body 53 is inserted into the inner side of the other end of the metal sleeve 1. A sealing ring is provided on the outer side of one end of the insulating body 53, and the sealing ring is in close contact with the inner wall of the metal sleeve 1. A radially convex retaining ring is also provided on the outer side of one end of the insulating body 53, and the radially convex retaining ring is tightly clamped between the end face of the other end of the metal sleeve 1 and the stepped surface between the inner end and the other end of the metal nut sleeve. The electrical connection between the metal nut sleeve and the metal sleeve 1 forms a comprehensive shielding structure, ensuring complete shielding against external interference signals during conductor signal transmission. The insulating body 53 and the metal sleeve 1 are in sealed contact, providing sufficient protection for the conductor.
