Description

Technical Field

[0001] This utility model relates to a detachable European-style rear connector. Background Technology

[0002] European-style rear-connector joints are widely used in high-voltage cable connections, primarily for mechanical and electrical connections between cables and equipment. They typically consist of an insulating cylinder, a grounding structure, and cable fixing components. Traditional European-style rear-connector grounding structures usually use grounding lugs and grounding cables secured with bolts or by winding them around the cable to complete equipment grounding. With the increasing complexity of power systems and higher performance requirements for equipment, existing rear-connector grounding structures have revealed the following main drawbacks in practical use: 1. Traditional grounding structures only design the grounding lugs of the rear connector, neglecting the grounding requirements of the main cable shielding layer installed inside the connector. Grounding the main cable shielding layer is crucial for ensuring system electromagnetic compatibility and eliminating induced current in the shielding layer. Traditional grounding structures cannot effectively ground the shielding layer, easily leading to increased electromagnetic interference and incomplete grounding, affecting system stability; 2. Existing grounding structures have a relatively simple design, usually only suitable for specific specifications of grounding cables or cable sizes. They lack adaptability to different cable models or complex installation environments, limiting their application range. Therefore, improvements and optimizations are needed to address these issues.

The rear connector wiring channel is used for the connection of the main cable. The rear connector grounding block includes an arc-shaped contact portion that contacts the shielding layer of the main cable and a grounding block body connected to the grounding cable. The inner wall of the rear connector wiring channel has a rear connector inner positioning groove for positioning the arc-shaped contact portion. The cylinder grounding lug has a grounding lug positioning groove for positioning the grounding block body. The grounding block body has a laterally penetrating grounding connection hole. The end of the grounding cable has a cable docking plate, and the cable docking plate has docking plate fixing holes corresponding to the grounding connection hole. The rear connector grounding block is made of metal and is integrally injection molded with the rear connector cylinder.

[0005] The grounding block body has a grounding block limiting protrusion at the middle of the left and right ends, and the grounding connection hole is provided on the side of the grounding block limiting protrusion. The grounding ear of the cylinder has a grounding block limiting opening corresponding to the grounding block limiting protrusion.

[0006] The thickness of the arc-shaped contact portion is equal to the depth of the positioning groove inside the rear connector, and the arc-shaped contact portion is provided with spaced contact clamping teeth.

[0007] The tooth height of the contact clamping teeth is less than 0.5 mm.

[0008] The grounding connection hole is a threaded hole.

[0009] The grounding block body has a grounding block slot in the middle to facilitate the insertion of the cable docking plate.

[0010] The advantages of this detachable European-style rear connector are: it incorporates a rear connector grounding block for grounding the main cable shielding layer, integrates the rear connector grounding block with the rear connector cylinder through injection molding, and significantly improves grounding stability and reliability through contact clamping teeth and multi-point fixing structure, making grounding operation more convenient and more versatile.

[0017] like Figure 1-5As shown, the detachable European-style rear connector of this utility model includes a rear connector cylinder 1, a rear connector grounding block 2, and a grounding cable 3. The rear connector cylinder 1 has a cylinder grounding lug 4 on its exterior. The rear connector cylinder 1 has a horizontally arranged rear connector mating channel 5 and a vertically arranged rear connector wiring channel 6 communicating with the rear connector mating channel 5. The rear connector wiring channel 6 is used for the connection of the main cable. The rear connector grounding block 2 includes an arc-shaped contact portion 8 that contacts the shielding layer of the main cable and a grounding block body 9 connected to the grounding cable 3. The inner wall of the rear connector wiring channel 6 has a rear connector inner positioning groove 10 for positioning the arc-shaped contact portion 8. The cylinder grounding lug 4 has a... The grounding block body 9 is positioned by a grounding ear positioning groove 11. The grounding block body 9 is provided with a lateral through grounding connection hole 12. The end of the grounding cable 3 is provided with a cable docking plate 13. The cable docking plate 13 is provided with docking plate fixing holes 14 corresponding to the grounding connection hole 12. The rear connector grounding block 2 is made of metal and is integrally injection molded with the rear connector cylinder 1. The rear connector grounding block 2 is added for grounding the shielding layer of the main cable. The arc-shaped contact part 8 can make close contact with the shielding layer of the main cable, realizing multi-point simultaneous grounding. After grounding, the stability and reliability of the product are effectively improved. The rear connector grounding block and the rear connector cylinder are integrally injection molded, which enhances the overall structural strength and sealing performance.
