Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a waterproof self-locking connector. Background Technology

[0002] In the field of electronic device connectivity, connectors are key components for signal and power transmission, and their stability and protection performance directly affect the operation of the equipment.

[0003] In related technologies, connectors mostly only perform basic plugging and unplugging functions and lack effective anti-loosening structures. Under conditions such as vibration and tension, they are prone to loosening, leading to connection interruption and affecting the normal operation of equipment. In addition, traditional connectors have insufficient waterproof design, especially in humid or water-filled environments. Moisture can easily seep into the interior, causing short circuits or component corrosion, significantly shortening the connector's lifespan and making it difficult to meet the usage requirements of complex outdoor and industrial scenarios.

[0004] Currently, connectors on the market that combine anti-recognition and waterproof functions are either complex in structure and inconvenient to assemble, or have poor protective effects. Therefore, there is an urgent need for a connector with a simple structure, reliable anti-recognition and excellent waterproof performance to solve the pain points of existing technologies.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

The plug includes a second housing, a check mechanism, and a connecting part. The check mechanism and the connecting part are both located on the second housing. The check mechanism can be inserted into the mating channel and engage with the bayonet. A waterproof ring is fitted on the outer edge of the connecting part. The connecting part is configured to be inserted into the slot so that the waterproof ring contacts the inner side of the slot.

[0008] This connector, through the cooperation of a check mechanism and a bayonet, achieves a check-back and anti-reverse function between the plug and the socket. Furthermore, by incorporating a waterproof ring, it effectively prevents moisture from entering the slot, thus significantly improving the connector's waterproof performance.

[0017] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0018] like Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the waterproof self-locking connector provided in the embodiments of this application. Figure 2 for Figure 1 Side view of the plug.

[0019] One embodiment provides a waterproof self-locking connector, which includes a socket 100 and a plug 200.

[0020] The socket 100 includes a first housing 110, the first housing 110 is provided with a mating channel 111 along the insertion direction, the first housing 110 is provided with a bayonet 112, the bayonet 112 communicates with the mating channel 111, and the first housing 110 has a slot 113.

[0021] The first housing 110 is a component mounted on the device to be charged. It is understood that the device to be charged can be an electrically powered product such as an electric bicycle.

[0022] The first housing has an inner surface and an outer surface spaced apart. It is understood that the inner surface of the first housing faces the device to be charged, and the outer surface of the first housing faces away from the device to be charged.

[0023] The socket also includes a dust cap, which is fitted onto the inner surface of the first housing. The dust cap is a component used to cover the slot. By providing the dust cap, foreign objects or moisture can be prevented from entering when the socket is not plugged in.

[0024] The dust cap is fitted onto the inner surface of the first housing. It is understood that there are four sleeves on the inner surface of the first housing, all protruding from the inner surface. The dust cap includes a connecting plate, a connecting strap, and a cap body. The connecting plate has four holes for engaging with the sleeves. The connecting strap has a certain length to allow the cap body to cover the slots and mating channels. The cap body is connected to the connecting strap.

[0025] The mating channel 111 and the slot 113 are not connected. This design prevents external moisture from flowing into the slot 113 through the mating channel 111, thereby enhancing the connector's waterproof performance.

[0026] The plug 200 includes a second housing 210, a check mechanism 220, and a connecting part 230. The check mechanism 220 and the connecting part 230 are both disposed on the second housing 210. The check mechanism 220 can be inserted into the mating channel 111 and engage with the bayonet 112. A waterproof ring 240 is sleeved on the outer edge of the connecting part 230. The connecting part 230 is configured to be inserted into the slot 113 so that the waterproof ring 240 contacts the inner side of the slot 113.

[0027] The second housing 210 is a component mounted on the cable. The second housing 210 is typically a plastic component.

[0028] The second housing 210, the check mechanism 220, and the connector are integrally molded. The plug 200 has no seams, and the force applied to the check mechanism 220 is directly transmitted to the second housing 210. There is also no risk of relative displacement of components when the connector 230 is inserted into the slot 113. This integral molding structure eliminates the need for multi-component assembly, simplifying the production process and reducing assembly errors. It also eliminates structural weaknesses at joints, improving the overall structural strength of the plug 200 and preventing check failure or displacement of the waterproof ring 240 due to component loosening, further ensuring the stability of the anti-reverse and waterproof functions.

[0029] The anti-return mechanism 220 is a structure that prevents the plug 200 from returning. It can be understood that when the plug 200 is fully inserted into the socket 100, the anti-return mechanism 220 engages with the bayonet 112, thereby fixing the plug 200 to the socket 100, preventing the plug 200 from returning and thus improving the stability of the connection between the plug 200 and the socket 100.

[0030] The connecting part 230 is inserted into the slot 113 to achieve an electrical connection with the socket 100. The shape of the connecting part 230 matches the shape of the slot 113. The connecting part 230 has a connecting post that is electrically connected to the connecting pin on the first housing 110.

[0031] In this embodiment, the waterproof self-locking connector is used by aligning the anti-return mechanism 220 of the plug 200 with the mating channel 111 of the first housing 110 of the socket 100 and inserting it. When the anti-return mechanism 220 moves along the mating channel 111 to correspond to the position of the bayonet 112, the two automatically engage. Simultaneously, the connecting part 230 of the plug 200 is inserted into the slot 113 of the first housing 110 of the socket 100, and the waterproof ring 240 on the outer edge of the connecting part 230 makes tight contact with the inner side of the slot 113, completing the insertion assembly. When subjected to external pulling force, the engagement between the anti-return mechanism 220 and the bayonet 112 prevents the plug 200 from separating from the socket 100. The self-locking anti-retraction function of the connector is achieved through the cooperation of the anti-retraction mechanism 220 and the bayonet 112, avoiding loosening or interruption of the connection caused by vibration or pulling; the tight contact between the waterproof ring 240 and the inner side of the slot 113 creates an effective waterproof seal to prevent water infiltration, while covering the core assembly structure of the connector, taking into account both anti-retraction reliability and waterproof effectiveness, and adapting to complex working conditions.

[0032] The waterproof self-locking connector provided in this embodiment uses a check mechanism 220 to cooperate with the bayonet 112 to achieve a check and anti-reverse function between the plug 200 and the socket 100. Furthermore, by setting a waterproof ring 240, it can effectively prevent moisture from entering the slot 113, thereby effectively improving the waterproof performance of the connector.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the check mechanism 220 includes a pin 221 and a locking block 222. The pin 221 is disposed on the second housing 210, and the locking block 222 is disposed at the end of the pin 221. The pin 221 is configured to be inserted into the mating channel 111, and the locking block 222 is configured to engage with the bayonet 112.

[0034] The insert 221 is a component that is inserted into and mates with the mating channel 111. The shape of the insert 221 matches the shape of the mating channel 111.

[0035] The locking block 222 is a component that engages with the latch 112. When the plug 200 needs to be disengaged from the socket 100, downward pressure is applied to the locking block 222 at the latch 112 to disengage the locking block 222 from the latch 112, and then the plug 200 is pulled out.

[0036] During insertion, the plug 200's pin 221 is inserted along the mating channel 111 of the socket 100's first housing 110. The locking block 222 at the end of the pin 221 moves with the pin 221. When the locking block 222 reaches the locking position 112, it engages with the locking position 112. When an external force attempts to separate the plug 200 from the socket 100, the limiting relationship between the locking block 222 and the locking position 112 prevents the pin 221 from exiting the mating channel 111. The pin 221 can guide the anti-return path, avoiding locking failure caused by the locking block 222's offset, further improving the stability and feasibility of the anti-return function.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the latch 222 has a mating ramp 2221 and a stopping ramp 2222 spaced apart. The mating ramp 2221 is disposed toward the first housing 110, and the stopping ramp 2222 is disposed toward the second housing 210. The stopping ramp 2222 is configured to abut against the latch 112.

[0038] Specifically, the slope of the mating inclined plane 2221 is less than the slope of the stopping inclined plane 2222.

[0039] During insertion, the locking block 222 moves toward the socket 100. The mating bevel 2221 of the locking block 222 first contacts the mating channel 111, allowing the plug 221 to enter the mating channel 111. Once in position, the stop bevel 2222 of the locking block 222 abuts against the inner wall of the bayonet 112. When the plug 200 is under tension, the rigid contact between the stop bevel 2222 and the bayonet 112 prevents the locking block 222 from retracting. The mating bevel 2221 acts as a guide for insertion, reducing insertion resistance and improving assembly convenience. The stop bevel 2222 is positioned toward the second housing 210, maximizing the contact area with the bayonet 112, enhancing the stopping effect, and preventing the locking block 222 from deforming or slipping under tension, thus balancing insertion convenience and anti-retraction reliability.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the outer edge of the waterproof ring 240 is provided with a plurality of contact portions 241.

[0041] The contact portion 241 is a component that contacts the inner surface of the slot 113. The contact portion 241 has a ring-shaped structure and protrudes from the outer edge of the waterproof ring 240. When the connecting portion 230 is inserted into the slot 113 of the socket 100, multiple contact portions 241 on the outer edge of the waterproof ring 240 simultaneously contact the inner surface of the slot 113. Due to its protruding structure, the contact portions 241 can undergo slight deformation, filling the tiny gap between the waterproof ring 240 and the inner surface of the slot 113, forming multiple sealing contact points. Multiple contact portions 241 increase the sealing contact area between the waterproof ring 240 and the slot 113, significantly improving sealing reliability compared to a single planar contact. The protruding structure of the contact portion 241 can accommodate slight dimensional deviations in the inner surface of the slot 113, avoiding sealing failure due to processing errors and further optimizing waterproof performance.
