Specific implementation manner

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] It should be noted that the terms "comprising" and "having" in the description and claims of the present utility model and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0030] It should be noted that an energy storage connector is a type of common electrical connector, which includes a board-end socket fixed on the device housing and a wire-end plug that mates with the board-end socket for plugging. After the wire-end plug is plugged into the board-end socket, electrical connection can be achieved. For example, in the field of electric vehicles, such energy storage connectors are often used to charge the vehicle.

[0031] However, after the energy storage connector is powered on, it is easily affected by high-frequency pulse interference from high-power energy storage devices and high-frequency oscillation interference generated by transient current and parasitic oscillation caused by switch plugging and unplugging.

[0032] As Figures 1 - 5 shown, this embodiment provides a new type of magnetic-ring connector. The core wire 41 of the cable 40 can be evenly wound around multiple magnetic rings 20 with different turns through the cable inner lining 10, so that normal useful signals can pass through, effectively suppressing the passing of high-frequency interference signals, improving the connection performance and reliability, protecting the equipment from potential damage and faults, and fixing and protecting the magnetic rings 20 and the cable 40 by means of wrapping with a heat-shrinkable sleeve 30, improving the long-term reliable use of the product.

[0033] Specifically, the new type of magnetic-ring connector includes a plug body 100. Inside the plug body 100, there are a cable inner lining 10, magnetic rings 20 and a heat-shrinkable sleeve 30. The cable inner lining 10 is provided with a number of partition plates 11, and the partition plates 11 are evenly distributed on the cable inner lining 10; multiple magnetic rings 20 are sequentially sleeved outside the cable inner lining 10, and a number of partition chambers are formed between the magnetic rings 20 and the cable inner lining 10. The core wire 41 of the cable 40 is placed in the partition chambers, and after the core wire 41 bypasses multiple magnetic rings 20, one end faces the head end of the plug body 100 and the other end faces the tail end of the plug body 100; the heat-shrinkable sleeve 30 is arranged outside the magnetic rings 20 and the cable 40 for wrapping the multiple magnetic rings 20 and the cable 40. During the installation process, the heat-shrinkable sleeve 30 shrinks by heating and tightly adheres to the surfaces of the magnetic rings 20 and the cable 40, forming a solid protective layer, making the cable 40 and the magnetic rings 20 form an integral body.

[0034] The number and type of the magnetic rings 20 and the number of turns of the core wire 41 wound around the magnetic rings 20 are adjusted according to the specific use scenario of the plug body 100 and the frequency range to be suppressed, ensuring that the passing of high-efficiency interference signals can be suppressed to achieve the best interference suppression effect.

[0035] In one embodiment, an inner membrane 50 is further provided inside the plug body 100. The inner membrane 50 has a hollow internal structure. After the heat-shrinkable sleeve 30 wraps the magnetic rings 20 and the cable 40, it is placed in the hollow chamber of the inner membrane 50, and the inner wall of the inner membrane 50 tightly adheres to the magnetic rings 20 and the cable 40 wrapped by the heat-shrinkable sleeve 30.

[0036] Specifically, after the core wire 41 of the cable 40 winds around the magnetic rings 20, it is preliminarily wrapped by the heat-shrinkable sleeve 30. Using the heat shrinkage and insulation of the heat-shrinkable sleeve 30, the core wire 41 is preliminarily fixed and protected to prevent it from being damaged during subsequent processing.

[0037] After the initial wrapping, the magnetic ring 20 and the cable 40 as a whole are placed in the hollow chamber of the inner membrane 50, ensuring a tight fit between the heat shrinkable sleeve 30 and the inner membrane 50. At the same time, through appropriate fixing measures (such as adhesives), the heat shrinkable sleeve 30 is firmly limited within the inner membrane 50 to prevent it from shifting during use.

[0038] The addition of the inner membrane 50 makes the entire connector structure more stable and reliable. It can not only withstand greater external pressure and impact but also effectively prevent the loosening and deformation of the internal structure.

[0039] Preferably, several wire outlet holes 51 are provided at the head end of the inner membrane 50. The number of wire outlet holes 51 is the same as the number of core wires 41, which are used to allow the core wires 41 of the cable 40 to extend out of the inner membrane 50 and be connected to the current-carrying copper sheets 71. An integrated hole 52 is provided at the tail end of the inner membrane 50, through which the core wires 41 of the cable 40 are integrated and pass through.

[0040] In one embodiment, the plug body 100 includes a main housing 60 and an upper cover 70. The main housing 60 and the upper cover 70 are detachably connected. The inner membrane 50 is disposed within the main housing 60, and a slot 61 for restricting the movement of the inner membrane 50 is provided within the main housing 60.

[0041] The current-carrying copper sheet 71 is mounted on the upper cover 70. The current-carrying copper sheet 71 is connected to the core wire 41 facing the head end of the plug body 100, and the current-carrying copper sheet 71 is adapted to the conductor on the external socket body.

[0042] Preferably, the plug body 100 further includes a crimping copper row 72. The core wire 41 is clamped between the current-carrying copper sheet 71 and the crimping copper row 72, and the current-carrying copper sheet 71 and the crimping copper sheet are connected by screws.

[0043] A baffle 80 is provided between the upper cover 70 and the inner membrane 50. The baffle 80 and the upper cover 70 are connected by screws. Both the current-carrying copper sheet 71 and the crimping copper row 72 are located on the side of the baffle 80 away from the inner membrane 50.

[0044] The upper cover 70, the baffle 80, and the inner membrane 50 are connected by screws. By connecting the upper cover 70 to the inner membrane 50, the connection between the upper cover 70 and the main housing 60 is achieved.

[0045] In one embodiment, the upper cover 70 is provided with a first positioning groove 73 and a second positioning groove 74. The first positioning groove 73 is used to position the current-carrying copper sheet 71 to prevent the current-carrying copper sheet 71 from shaking and coming out of the upper cover 70. The second positioning groove 74 is used to position the crimping copper row 72 to prevent the crimping copper row 72 from shifting when moving the connector.

[0046] In one embodiment, anti-slip stripes are provided on the outside of the main housing 60 to increase the friction during holding and prevent slipping during plugging and unplugging.

[0047] It should be understood that those of ordinary skill in the art can make improvements or transformations according to the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of the present utility model.

[0048] The present utility model patent has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
