Description

Technical Field

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

[0002] DC connectors are commonly used for connecting low-voltage DC power supplies and are widely used in various electronic devices and low-voltage power systems, especially in charging equipment, charging heads, and battery-powered devices. Existing DC connectors are designed for friction-based fixation. During rotation, friction causes wear at the connection point. This wear can lead to poor contact or affect current conduction efficiency. Furthermore, due to friction and the incompletely fixed connection method, noise is generated at the connection point during rotation. This noise not only affects the user experience but can also cause unnecessary interference in some precision equipment, affecting its normal operation. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a universal charging head, comprising: The female base includes an outer tube two, one end of which is equipped with a bearing one; the other end of the outer tube two is equipped with a rubber ring, and a positive terminal is installed inside the rubber ring. The positive terminal is located inside the outer tube two and the bearing two is installed at one end. The male connector is located at one end of the female connector. The male connector includes an outer tube that mates with a bearing, and a center pin that mates with a bearing is installed inside the outer tube.

[0005] Preferably, a separator ring is fixed inside the outer tube 2 to separate the bearing 1 from the rubber ring.

[0006] Preferably, a welding piece is fixedly connected inside the outer tube two and between the separator ring and the rubber ring, and a grounding lug is fixedly connected to the end of the welding piece, with the end of the grounding lug protruding from one end of the outer tube two.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a universal charging head, comprising: a female connector 2, the female connector 2 including an outer tube 21, a bearing 22 fixedly installed inside one end of the outer tube 21; a rubber ring 24 installed at the other end of the outer tube 21, a positive terminal 26 installed inside the rubber ring 24, a mounting hole opened at one end of the positive terminal 26 inside the outer tube 21, a bearing 25 fixedly installed inside the mounting hole; a male connector 1 inserted into one end of the female connector 2, the male connector 1 including an outer tube 12 that mates with the inner ring of the bearing 22, a center pin 11 that mates with the inner ring of the bearing 25 installed inside the outer tube 12, the center pin 11, the outer tube 12 and the outer tube 21 are all made of C3604 environmentally friendly copper material.

[0016] It should be noted that in this embodiment, bearing 1 22, outer tube 2 21, bearing 2 25, and positive terminal 26 are concentric, and outer tube 1 12 is concentric with center pin 11. During installation, one end of center pin 11 is inserted into bearing 1 22 from one end of outer tube 2 21. During this period, the end of center pin 11 passes through the middle of bearing 1 22 and engages with the inner ring of bearing 2 25. Outer tube 1 12 is inserted into the inner ring of bearing 1 22. Center pin 11 and positive terminal 26 are connected through bearing 2 25, and both are connected to the positive terminal. Outer tube 1 12 and outer tube 2 21 are connected through bearing 1 22, and both are connected to the negative terminal. Under the action of bearing 1 22 and bearing 2 25, the two poles can rotate independently without wear and without rotational noise.

[0017] In one embodiment, a partition ring 28 is fixedly connected inside the outer tube 21 to separate the bearing 22 and the rubber ring 24. A welding piece 23 is fixedly connected inside the outer tube 21 and between the partition ring 28 and the rubber ring 24. A grounding lug 27 is fixedly connected to the end of the welding piece 23, and the end of the grounding lug 27 extends out from one end of the outer tube 21.

[0018] It should be noted that in this embodiment, the separator ring is located inside the outer tube 2 and separates the bearing 1 and the rubber ring 24, ensuring that the space between them will not interfere or contact, and it can position the installation of the bearing 1 22. The welding piece 23 is fixed between the separator ring 28 and the rubber ring 24. The welding piece helps to conduct electricity and ensures that the grounding system is stably connected to the negative terminal. The grounding lug 27 is connected to the outer tube 2 through the welding piece and plays a grounding role.

[0019] In one embodiment, one end of the rubber ring 24 has a hole for inserting the center pin 11, one end of the center pin 11 has a stepped surface that mates with the inner ring of the bearing 25, one end of the outer tube 12 is fixedly connected to the rubber core 13, and the center pin 11 is fixedly connected to the rubber core 13. Both the rubber ring 24 and the rubber core 13 are made of PBT material.

[0020] It should be noted that in this embodiment, one end of the rubber ring 24 has a hole for the insertion of the center pin 11. This allows the center pin to engage with the bearing 25 at the end of the positive terminal 26, while preventing excessive friction between the center pin 11 and other objects, thus ensuring rotational freedom. One end of the center pin 11 has a stepped surface, which engages with the inner ring of the bearing 25. The stepped surface blocks and positions the insertion depth, ensuring the stability and accuracy of the connection. The connection between the center pin and the outer tube 12 is fixed by the rubber core 13. This not only ensures a firm connection between the center pin and the outer tube, but also guarantees reliability during long-term use due to the stability of the rubber core 13. The PBT material of the rubber ring 24 and the rubber core 13 has high heat resistance and anti-aging properties, maintaining stable physical properties during long-term use, making it suitable for use in high-temperature and high-pressure environments.
