Description

Technical Field

[0001] This utility model relates to connector technology, specifically to a magnetic floating battery connector, which is particularly suitable for electrical connection scenarios with high requirements for vibration and shock resistance and connection reliability, such as ebikes, drones, robots, and portable medical devices. Background Technology

[0002] Magnetic connectors are widely used in devices that require frequent mating and high connection stability due to their convenient blind mating and superior connection experience. To compensate for positional deviations during the mating process, floating connection technology has been commonly incorporated into magnetic connector designs to adapt to vibration, displacement, and other operating conditions of the equipment.

[0003] However, existing magnetic floating battery connectors still have the following technical problems that urgently need to be solved:

[0004] Uncontrollable floating range: Existing products mostly rely on simple springs or silicone sleeves to achieve the floating function, lacking a precise rigid limiting structure. When subjected to excessive impact or vibration, the floating component is prone to excessive displacement. This can result in interference with surrounding components, or even the strong attraction of the internal magnets pulling the component to its limit position, causing jamming and directly affecting the continuity of the connection.

[0005] The contradiction between floating and sealing: The floating function relies on the movement gap between components, but this gap can compromise the overall sealing of the connector. Dust and moisture can easily enter the interior through the gap at the tail of the connector, corroding the conductive terminals, reducing terminal contact reliability, and shortening the connector's lifespan.

[0006] Insufficient guidance and damage prevention: During magnetic docking, the strong attraction of the magnet may cause the male and female ends to quickly engage at an inclined angle. This non-coaxial docking method is prone to deformation and damage to the precision structure of the female PIN hole, which not only affects the smoothness of subsequent insertion and removal, but also leads to poor terminal contact and causes electrical signal transmission failure.

[0007] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a magnetic floating battery connector to solve the above problems. Utility Model Content

[0008] To address the shortcomings of existing technologies, the core objective of this utility model is to provide a magnetic floating battery connector. By optimizing the structural design, it solves the technical problems of uncontrollable floating range, poor sealing performance, and easy damage during connection of existing products. At the same time, it also takes into account the anti-vibration and anti-tension performance, and achieves long-term stable electrical connection.

[0010] The preferred technical solution is that the first magnet and the second magnet are arranged to correspond to each other and have opposite magnetic poles.

[0012] The preferred technical solution is that the PIN arrangement of the male terminal and the female terminal adopts a symmetrical design.

[0013] The preferred technical solution is that the floating silicone sleeve, the female end insulating shell, and the floating limit protection component together constitute an integrated floating sealing structure.

[0014] The preferred technical solution is as follows: the anti-collision bracket includes a connecting ring and two limiting wings forming the outer periphery of the connecting ring, the two limiting wings being arranged opposite to each other; the connecting ring is fixedly connected to the tail end of the female end insulating shell.

[0015] The preferred technical solution is that the anti-collision bracket and the female end insulating shell are assembled by means of snap-fit ​​connection or screw fixation.

[0016] The preferred technical solution is as follows: the limiting rear cover includes a limiting ring and two support feet formed on the front side of the limiting ring. The two support feet are arranged opposite to each other and are used to fix them to the flange panel. Two limiting spaces are formed between the two support feet, and two limiting wings are arranged in the two limiting spaces one to one.

[0018] A preferred technical solution is that the outer periphery of the female end insulating shell is further provided with a sealing ring for sealing the insertion point with the male end insulating shell.

The floating limiting protection component 7 includes an anti-collision bracket 71 and a limiting rear cover 72. The anti-collision bracket 71 is fixedly connected to the female insulating shell 3, and the limiting rear cover 72 is fixedly connected to the flange panel 5. When the female insulating shell 3 is displaced in the up-down, left-right, or rotational direction beyond a preset angle, the anti-collision bracket 71 contacts the limiting rear cover 72 to prevent the female insulating shell 3 from displacing further.

[0031] Specifically, the vertical and horizontal (circumferential) limiting is achieved by the flange panel 5 limiting the circumferential of the female end insulating shell 3; the front and rear (axial) limiting is achieved by the flange panel 5 limiting the front side of the anti-collision bracket 71 and the limiting rear cover 72 limiting the rear side of the anti-collision bracket 71; the rotation angle limiting is achieved by the limiting rear cover 72 limiting the rotation angle of the anti-collision bracket 71.

[0032] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, magnet one and magnet two correspond to each other and are arranged with opposite magnetic poles.

[0033] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, the male terminal 2 includes a male power terminal 21 and a male signal terminal 22, and the female terminal 4 includes a female power terminal 41 and a female signal terminal 42.

[0034] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, the PIN arrangement of the male terminal 2 and the female terminal 4 adopts a symmetrical design.

[0035] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, the floating silicone sleeve 6, the female end insulating shell 3, and the floating limit protection component 7 together constitute an integrated floating sealing structure.

[0036] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, the anti-collision bracket 71 includes a connecting ring 711 and two limiting wings 712 formed on the outer periphery of the connecting ring 711, the two limiting wings 712 being arranged opposite to each other; the connecting ring 711 is fixedly connected to the tail end of the female end insulating shell 3.

[0037] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, the anti-collision bracket 71 and the female end insulating shell 3 are assembled by means of snap-fit ​​connection or screw fixation.

The two support feet 722 are arranged opposite to each other and are used to fix them to the flange panel 5. Two limiting spaces are formed between the two support feet 722, and two limiting wings 712 are correspondingly provided in the two limiting spaces.

[0039] like Figures 1 to 5As shown, in an exemplary embodiment of this utility model, the female end insulating housing 3 is provided with a foolproof slot 31 at its plug-in end, and the male end insulating housing 1 is provided with a foolproof pin 11 at its plug-in end.

[0040] like Figures 1 to 5 As shown, in an exemplary embodiment of this utility model, a sealing ring 8 is also provided on the outer periphery of the female end insulating shell 3 for sealing the insertion point with the male end insulating shell 1.

[0041] Therefore, this utility model has the following advantages:

[0042] Solving the problem of uncontrollable floating range: Through the rigid limiting design of the floating limit protection component (anti-collision bracket + limit back cover), the female end insulation shell can be precisely limited in the up, down, left, right and rotation directions, avoiding interference or jamming caused by excessive displacement. At the same time, the floating silicone sleeve absorbs vibration stress, protects the welding points, and improves vibration resistance and tensile strength.

[0043] To resolve the conflict between floating and sealing: The interference fit between the floating silicone sleeve and the female end insulating shell and flange panel, combined with the sealing ring of the female end plug end, forms an integrated floating sealing structure, which effectively blocks the intrusion path of dust and moisture, stably achieves IP67 level sealing, and avoids terminal corrosion.

[0044] Solving guidance and damage prevention issues: The magnet design with opposite magnetic poles ensures coaxial magnetic attraction between the male and female ends. The foolproof pin and foolproof slot further limit the docking angle, avoiding damage to the female PIN hole caused by tilting and extending the insertion and removal life.

[0045] Balancing versatility and reliability: The symmetrical PIN arrangement can be adjusted according to requirements (such as 2+3, 2+4 structure) to adapt to different power and signal transmission needs; the overall structure significantly reduces the probability of failure under harsh working conditions and extends the overall service life of the connector through the coordinated design of buffering, limiting and sealing.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
