Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a waterproof connector. Background Technology

[0002] As a common electrical connection element, connectors are widely used in various electronic devices for transmitting power or signals. In daily life and industrial environments, connectors are often exposed to harsh conditions such as moisture, splashes, or dust, for example, in outdoor equipment, kitchen appliances, and bathroom electronics. However, traditional connectors are often designed with electrical connection functionality in mind, neglecting waterproofing. This makes them susceptible to moisture ingress in humid environments, unable to withstand damp, water-filled, or dusty conditions, leading to short circuits, corrosion, or signal transmission failures, seriously affecting the lifespan and safety of the equipment.

[0003] Specifically, when the plug of an existing connector mates with the socket of an electronic device, a tiny gap inevitably exists between their contact surfaces, and this gap lacks any sealing or waterproofing components. Furthermore, the plug itself lacks a protective structure to prevent moisture intrusion. This design flaw allows moisture from the external environment (such as water vapor in a bathroom, rainwater outdoors, condensation in industrial settings, or splashes during washing) to easily seep into the connector through this gap or directly contact the conductive areas of the plug. Therefore, a waterproof connector is provided to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof connector to address the shortcomings of existing technologies, thereby solving the technical problem that existing connectors do not have a waterproof effect.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A waterproof connector includes a plug portion and a connecting wire electrically connected to the plug portion. The plug portion has a tongue at the end away from the connecting wire, and a fixing member at the end of the plug portion near the tongue. The fixing member has an annular suction cup portion on the side near the tongue, and the concave surface of the suction cup portion faces the same direction as the tongue. The fixing member also has a groove portion formed on the side where the suction cup portion is located, and an annular sealing ring is installed in the groove portion.

[0006] Furthermore, the suction cup part is a plastic suction cup.

[0007] Furthermore, the sealing ring is a silicone ring.

[0008] Furthermore, a fixing housing is installed on the side of the fixing member away from the suction cup part, and a venting component is provided inside the fixing housing to release the suction cup part under negative pressure.

[0009] Furthermore, the venting component includes a venting pipe disposed inside the fixed housing. One end of the venting pipe is an open end, and the other end is a sealed end. The open end of the venting pipe passes through the fixing member and the suction cup in sequence. The venting pipe is a straight pipe, and its length direction is consistent with the extension direction of the tongue. A venting hole is formed on the periphery of the venting pipe. A plugging sleeve is slidably fitted on the outer side of the venting pipe. A sealing sleeve is provided on the inner side wall of the plugging sleeve for blocking the venting hole. The fixed housing is formed with a through hole for communicating its interior with the outside air.

[0010] Furthermore, the opening end of the vent pipe is flush with the concave surface of the suction cup.

[0011] Furthermore, the sealing sleeve is a silicone sleeve.

[0012] Furthermore, a movable frame is slidably provided on the outer side of the fixed housing, and the sliding direction of the movable frame is consistent with the sliding direction of the plugging sleeve. A connecting block is provided on the outer side of the plugging sleeve, and the connecting block passes through the fixed housing and is fixedly connected to the inner side wall of the movable frame.

[0013] Furthermore, the outer surface of the movable frame is formed with several anti-slip protrusions.

[0014] Furthermore, a guide rod is fixedly provided on the inner side wall of the fixed housing, with its length direction parallel to that of the vent pipe. A slider is also provided on the outer side of the plug sleeve. The slider is slidably disposed on the guide rod. A spring is wound around the guide rod and placed between the slider and the inner side wall of the fixed housing to apply a force to the slider in the direction of the suction cup.

[0015] The beneficial effects of this utility model are as follows: When this connector is needed, the tongue on the plug is inserted into the designated socket of the electronic device. During the insertion process, the suction cup contacts the surface of the electronic device and pressure is applied to the suction cup. The air inside the suction cup is pressed out and a negative pressure state is maintained, so that the suction cup adheres to the surface of the electronic device. This not only improves the connection effect of this connector, but also improves the waterproof effect.

[0016] In addition, after the tongue is inserted into the socket of the electronic device, the sealing ring fills the gap between the fixing part and the electronic device, and together with the suction cup, it further improves the waterproof effect. Attached Figure Description

Detailed Implementation

[0024] The following is a detailed description of a waterproof connector according to the present invention, with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, an embodiment of the waterproof connector of this utility model includes a plug part 1 and a connecting line 2 electrically connected to the plug part 1. The end of the plug part 1 away from the connecting line 2 is provided with a tongue part 3, which is used to be plugged into the socket of an electronic device to realize the transmission of electricity or signals after plugging.

[0026] A retaining member 4 is provided at one end of the plug portion 1 near the tongue portion 3. The retaining member 4 is located at the base of the tongue portion 3. A ring-shaped suction cup portion 5 is installed on the side of the retaining member 4 near the tongue portion 3, and the concave surface of the suction cup portion 5 faces the same direction as the tongue portion 3. The suction cup portion 5 can be a plastic suction cup made of soft polyvinyl chloride (PVC). When this connector is needed, the tongue portion 3 on the plug portion 1 is inserted into the designated socket of the electronic device. During the insertion process, the suction cup portion 5 contacts the surface of the electronic device, and pressure is applied to the suction cup portion 5. The air inside is forced out, and a negative pressure state is maintained, so that the suction cup portion 5 is adsorbed on the surface of the electronic device. This improves the connection effect of this connector and also improves the waterproof effect.

[0027] like Figure 3-4 As shown, the side of the fixing member 4 where the suction cup part 5 is provided also has a groove part 6. The groove part 6 is equipped with an annular sealing ring 7, which can be a silicone ring. After the tongue part 3 is inserted into the socket of the electronic device, the sealing ring 7 fills the gap between the fixing member 4 and the electronic device. With the joint action of the suction cup part 5, the waterproof effect is further improved.

[0028] A fixing housing 8 is installed on the side of the fixing member 4 away from the suction cup part 5. The fixing housing 8 has a venting component inside for venting the suction cup part 5 when it is under negative pressure. The venting component is initially in a sealed state. After the suction cup part 5 is attached to the surface of the electronic device, the concave surface of the suction cup part 5 and the surface of the electronic device form a negative pressure chamber. Adsorption force is generated by the pressure difference between the external atmospheric pressure and the internal negative pressure. When it is necessary to unplug the plug part 1 from the socket of the electronic device, the venting component is opened, and the outside air enters the negative pressure chamber, causing the suction cup part 5 to stop adhering to the electronic device. Under the action of the venting component, it is easy to unplug the plug part 1, which improves the user experience.

[0029] like Figure 5-6 As shown, the venting component includes a venting pipe 9 disposed inside the fixed housing 8. One end of the venting pipe 9 is open, and the other end is sealed. The open end of the venting pipe 9 passes sequentially through the fixing member 4 and the suction cup portion 5, and the open end is flush with the concave surface of the suction cup portion 5. When the suction cup portion 5 is adsorbed onto the surface of the electronic device, the open end of the venting pipe 9 communicates with the negative pressure chamber. The venting pipe 9 is a straight pipe, and its length direction is consistent with the extension direction of the tongue portion 3.

[0030] The vent pipe 9 has vent holes 10 formed around its periphery. A blocking sleeve 11 is slidably fitted onto the outer side of the vent pipe 9. The inner wall of the blocking sleeve 11 has a sealing sleeve 12 for blocking the vent holes 10. The fixed housing 8 has a through hole 81 for communicating with the outside air. The sealing sleeve 12 is a silicone sleeve. The initial state of the sealing sleeve 12 is blocking the vent holes 10. When it is necessary to vent the negative pressure chamber, force is applied to the blocking sleeve 11 to make it slide on the outside of the vent pipe 9, thereby sliding the sealing sleeve 12 together. After sliding until the sealing sleeve 12 is misaligned with the vent holes 10 (i.e., the vent holes 10 are not blocked), outside air enters the fixed housing 8 through the through hole 81, and then enters the negative pressure chamber through the vent holes 10 and the vent pipe 9, causing the suction cup part 5 to stop adsorbing electronic devices.

[0031] In this embodiment, to facilitate applying force to the plugging sleeve 11, a movable frame 14 is slidably provided on the outer side of the fixed housing 8, and the sliding direction of the movable frame 14 is consistent with the sliding direction of the plugging sleeve 11. A connecting block 13 is provided on the outer side of the plugging sleeve 11, and the connecting block 13 passes through the fixed housing 8 and is fixedly connected to the inner sidewall of the movable frame 14. After pulling the movable frame 14 to slide away from the suction cup part 5, the plugging sleeve 11 is driven to slide together through the connecting block 13. After sliding to the designated position, the air release can be achieved. In addition, a number of anti-slip protrusions 15 are formed on the outer surface of the movable frame 14. By setting the anti-slip protrusions 15, the surface will slip when the user pulls the movable frame 14.

[0032] A guide rod 17, parallel in length to the vent pipe 9, is fixed to the inner wall of the fixed housing 8. A slider 16 is also provided on the outer side of the blocking sleeve 11. The slider 16 is slidably mounted on the guide rod 17. A spring 18 is wound around the guide rod 17 and placed between the slider 16 and the inner wall of the fixed housing 8 to apply a force to the slider 16 in the direction of the suction cup 5. After the blocking sleeve 11 slides away from the suction cup 5, it slides along the guide rod 17 with the slider 16. At this time, the spring 18 is gradually compressed. When outside air enters the negative pressure chamber, the movable frame 14 can be released. Under the action of the compressed spring 18, a force is applied to the slider 16 in the direction of the suction cup 5, thereby pushing the blocking sleeve 11 to slide back in the opposite direction on the vent pipe 9. The movable frame 14 also resets, thus re-blocking the vent hole 10 and achieving automatic reset. This makes it easier for the suction cup 5 to adsorb electronic devices when the plug 1 is plugged in next time. The operation is simple and further improves the user experience.

[0033] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0034] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
