Description

Technical Field

[0001] This utility model relates to the field of charging connector technology, and specifically to a safety charging connector. Background Technology

[0002] A charging connector is a device used to connect a power source and electronic equipment to enable power transmission and thus charge the device. It includes an interface portion and a cable portion.

[0004] However, the interface and cable of the aforementioned charging connector are fixedly connected. The cable is frequently pulled at multiple angles during use, which makes the fixed part of the cable and interface prone to large-angle bending, causing cracks on the outer surface of the cable and exposing the internal wire core. This affects the stability of the connector connection and reduces the safety of the charging connector. Utility Model Content

[0005] In view of the problems existing in the above-mentioned safety charging connectors, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a safe charging connector that solves the problem that the fixed part of the cable and the interface is prone to large-angle bending, which causes the outer surface of the cable to crack and exposes the internal wire core.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A safety charging connector includes an interface and a cable, wherein a protective cover is fixedly provided on the side of the interface near the cable, and the cable is fixedly passed through the side of the protective cover.

[0009] The interface has a rotating component on the side near the cable, and an outer conductive ring is provided through the rotating component. An inner conductive ring is rotatably inserted through the inner wall of the outer conductive ring. The cable is fixedly connected to the inner conductive ring. A current-carrying wire is connected between the outer conductive ring and the inside of the interface. A rotating groove is provided on the side of the interface near the cable to cooperate with the rotation of the outer conductive ring.

[0010] Preferably, the protective cover is an insulating silicone soft cover.

[0011] Preferably, the rotating assembly includes a vertical plate and a rotating rod. The vertical plate is fixedly connected to the side of the interface near the cable. One end of the rotating rod is rotatably disposed inside the vertical plate, and the other end of the rotating rod is fixedly connected to an external conductive ring.

[0012] Preferably, the inner wall of the outer conductive ring is fixed with two symmetrically arranged rubber support rings, and the inner conductive ring is disposed between the two rubber support rings.

[0013] Furthermore, the vertical plate is a plastic plate, the rotating rod is a plastic rod, and the rotating rod rotates with the inside of the vertical plate through an outer insulating bearing.

[0014] Preferably, both the outer conductive ring and the inner conductive ring are annular electrical contacts.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model, through its provided interface, cable, protective cover, rotating component, outer conductive ring, and inner conductive ring, can ensure a stable connection between the cable and the interface, while allowing the cable to rotate to any angle without external cracking, thereby improving the overall strength and safety of the charging connector.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a safe charging connector.

[0026] This utility model provides, for example Figure 1-3 The safety charging connector shown includes an interface 1 and a cable 2. A protective cover 3 is fixedly provided on the side of the interface 1 near the cable 2. The protective cover 3 is an insulating silicone soft cover. The cable 2 is fixedly passed through the side of the protective cover 3.

[0027] A rotating assembly is provided on the side of interface 1 near cable 2, and an outer conductive ring 4 is provided through the rotating assembly. An inner conductive ring 5 is rotatably inserted through the inner wall of the outer conductive ring 4. Both the outer conductive ring 4 and the inner conductive ring 5 are annular electrical contacts. Two symmetrically arranged rubber support rings 9 are fixedly provided on the inner wall of the outer conductive ring 4. The inner conductive ring 5 is located between the two rubber support rings 9. Cable 2 is fixedly connected to the inner conductive ring 5. A current-carrying wire 6 is connected between the outer conductive ring 4 and the interior of interface 1. A rotating groove 10 is provided on the side of interface 1 near cable 2 to cooperate with the rotation of the outer conductive ring 4.

[0028] When the charging connector is in use, cable 2 is connected to the inner conductive ring 5. Since both the inner conductive ring 5 and the outer conductive ring 4 are connected to the annular electrical contact, the inner conductive ring 5 can make electrical contact with the outer conductive ring 4 when it rotates with cable 2. This allows the interface 1 to be connected to the external power supply equipment through the power-carrying wire 6, so that power can be stably delivered to the connector for use. At this time, because the outer conductive ring 4 and the inner conductive ring 5 rotate relative to each other, and with the setting of the rotating component, cable 2 can rotate at any angle without the outer sheath cracking, ensuring the stable and safe use of the charging connector.

[0029] In order to allow cable 2 to rotate at any angle, such as Figure 2-3 As shown, the rotating assembly includes a vertical plate 7 and a rotating rod 8. The vertical plate 7 is fixedly connected to the side of the interface 1 near the cable 2. One end of the rotating rod 8 is rotatably located inside the vertical plate 7, and the other end of the rotating rod 8 is fixedly connected to the external conductive ring 4. The vertical plate 7 is a plastic plate, and the rotating rod 8 is a plastic rod. The rotating rod 8 rotates with the inside of the vertical plate 7 through its outer insulating bearing.

[0030] When the cable 2 can rotate laterally following the inner conductive ring 5, the cable 2 can also be flipped longitudinally through the rotational cooperation between the rotating rod 8 and the vertical plate 7, thereby increasing the rotational range of the cable 2 and improving the versatility of the charging connector.

[0031] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
