Description

Technical Field

[0001] This utility model relates to the technical field of connectors, specifically to a connector with a waterproof cover. Background Technology

[0002] Whether it's a connector between a power source and a wire, or a connector between circuits, they usually include plugs and connectors that can be plugged together to connect the circuit. However, currently, the connection between plugs and connectors generally uses a snap-fit ​​structure to fix them together, which makes it easy to connect or disconnect them.

[0003] Most connectors use an integrated shell, making it easy for rainwater to enter the car charging port and the connector nozzle from the connection point. This can damage the connector and the electronic components inside. Furthermore, the lack of a positioning mechanism on the outside of the connector means that it cannot be suspended after power is connected, making it prone to moisture damage. Utility Model Content

[0004] The purpose of this invention is to provide a connector with a waterproof cover to solve the above-mentioned defects caused by the prior art.

[0005] A plug connector with a waterproof cover includes a cylindrical body, a plug housing, a horizontal handle, and a rubber-toothed airtight zipper. One side of the plug housing is heat-pressed onto the cylindrical body. A power terminal is internally connected to the plug housing and located at the inner end of the cylindrical body. A protective mechanism is provided on the outer side of the plug housing to completely cover the outer side of the plug housing, preventing rainwater from seeping in through gaps and causing a short circuit on the circuit board. A rubber sleeve is provided on the outer side of the plug housing, and a positioning mechanism is located directly above the rubber sleeve. The positioning mechanism adjusts the height of the horizontal handle according to the usage position of the plug housing.

[0006] Preferably, the protective mechanism includes a rubber sleeve, a rectangular sleeve, a fastener, an inner thread tube body, a rubber pad, and a rubber-toothed airtight zipper. The rubber sleeve has a rubber-toothed airtight zipper on its back. The bottom end of the rubber sleeve is heat-pressed to a rectangular sleeve. The top end of the rubber sleeve is fitted with a rubber pad. The outer side of the rubber pad is connected to a fastener. The tail end of the fastener is connected to an inner thread tube body. The bottom end of the inner thread tube body is provided with a plug housing, which is located inside the rubber sleeve.

[0007] Preferably, the rubber sleeve is connected to the outer side of the T-shaped rod by rectangular sleeves on both sides, and both the T-shaped rod and the rectangular sleeves have positioning holes.

[0008] Preferably, the rubber sleeve is connected to the interior of the internal dental tube body via a fastener that passes through the top end, and the internal dental tube body is arranged parallel to the fastener.

[0009] Preferably, the positioning mechanism includes a horizontal handle, a nut, a T-bar, a side guide sleeve, and positioning holes. Nuts are symmetrically arranged at the top of the horizontal handle, which is positioned directly above the rubber sleeve. The T-bar is inserted through the inside of the side guide sleeve, and positioning holes are equally spaced on the outer side of the T-bar. The side guide sleeve is heat-pressed to connect the two sides of the rubber sleeve.

[0010] Preferably, the lateral grip is connected to the outer side of the side guide sleeve via T-shaped rods symmetrically arranged at the bottom.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The rubber sleeve is connected to the plug housing via a back-mounted airtight zipper, forming a wrap-around protection. The through-connection between the rectangular sleeve and the T-shaped rod further fixes the position of the rubber sleeve, preventing it from shifting under vibration or impact. The threaded connection between the fastener and the internal thread tube body applies axial pressure to the plug housing, ensuring the stability of the connection between the housing and the rubber sleeve. This design effectively prevents rainwater from entering from any gaps in the plug housing, such as around the seams, solving the problem of easy leakage in the partial sealing of traditional plugs.

[0012] 2. Both the T-bar and the rectangular sleeve have positioning holes. By using fasteners, positioning holes of different heights can be connected to achieve height adjustment of the lateral handle. This makes it easy for operators to position the lateral handle, rubber sleeve, and plug housing, preventing them from falling to the ground and getting damp. The through connection between the rectangular sleeve and the T-bar further fixes the position of the rubber sleeve, preventing it from shifting under vibration or impact. The side guide sleeve, as a guide carrier for the T-bar, provides linear guidance for the movement of the lateral handle, preventing the handle from shifting during adjustment.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1 to 5 As shown, a plug connector with a waterproof cover includes a cylindrical body 3, a plug housing 5, a horizontal handle 8, and a rubber-toothed airtight zipper 16. The cylindrical body 3 is heat-pressed to one side of the plug housing 5. A power terminal 4 is connected through the interior of the plug housing 5 and is located at the inner end of the cylindrical body 3. A protective mechanism 7 is provided on the outer side of the plug housing 5. The protective mechanism 7 covers the entire outer side of the plug housing 5 to prevent rainwater from seeping in through the gaps in the plug housing 5 and causing a short circuit in the circuit board. A rubber sleeve 1 is provided on the outer side of the plug housing 5. A positioning mechanism 9 is provided directly above the rubber sleeve 1. The positioning mechanism 9 adjusts the height of the horizontal handle 8 according to the usage position of the plug housing 5.

[0017] In this embodiment, the protective mechanism 7 includes a rubber sleeve 1, a rectangular sleeve 2, a fastener 6, an internal thread tube 14, a rubber pad 15, and a rubber-toothed airtight zipper 16. The rubber sleeve 1 has a rubber-toothed airtight zipper 16 on its back. The bottom end of the rubber sleeve 1 is heat-pressed to the rectangular sleeve 2. The top end of the rubber sleeve 1 is fitted with the rubber pad 15. The outer side of the rubber pad 15 is connected to the fastener 6. The tail end of the fastener 6 is connected to the internal thread tube 14. The bottom end of the internal thread tube 14 is provided with a plug housing 5, which is located inside the rubber sleeve 1. The rubber sleeve 1 is connected to the outer side of the T-shaped rod 11 through the rectangular sleeves 2 on both sides. Both the T-shaped rod 11 and the rectangular sleeve 2 have positioning holes 13. The rubber sleeve 1 is connected to the inside of the internal thread tube 14 through the fastener 6 at its top end. The internal thread tube 14 and the fastener 6 are arranged parallel to each other.

[0018] Among them, the rubber sleeve 1 and the rectangular sleeve 2 wrap around the outside of the plug housing 5 to form a surrounding sealed space to prevent liquid from seeping in from the side or top. The plug housing 5 and the rubber sleeve 1 are vertically positioned by the threaded connection of the fastener 6 to the internal thread tube body 14.

[0019] In this embodiment, the positioning mechanism 9 includes a horizontal handle 8, a nut 10, a T-shaped rod 11, a side guide sleeve 12, and positioning holes 13. The top end of the horizontal handle 8 is symmetrically provided with nuts 10, and the horizontal handle 8 is positioned directly above the rubber sleeve 1. The T-shaped rod 11 is inserted through the inside of the side guide sleeve 12, and positioning holes 13 are equally spaced on the outer side of the T-shaped rod 11. The side guide sleeve 12 is heat-pressed to connect the two sides of the rubber sleeve 1. The horizontal handle 8 is connected to the outer side of the side guide sleeve 12 through the T-shaped rods 11 symmetrically provided at the bottom end.

[0020] The T-shaped rod 11 passes through the inside of the side guide sleeve 12, and the outside of the T-shaped rod 11 is fixed to the horizontal handle 8 by the nut 10. This design can effectively resist the loosening of the columnar body 3 of the plug housing 5 due to vibration, impact or external force during use, and ensure the long-term stability of the connection between the horizontal handle 8, the rubber sleeve 1 and the plug housing 5, and avoid the impact of component displacement on waterproof performance or operating feel.

[0021] In practical applications, this type of connector with a waterproof cover includes the following functions: Step 1: Before use, according to the installation position or the positioning requirements of the plug housing 5, the operator first aligns the horizontal handle 8 with the top of the T-shaped rod 11, and then positions it using the nut 10 and bolt. Then, the horizontal handle 8 and the T-shaped rod 11 are installed. At the same time, the horizontal handle 8 pulls the T-shaped rod 11 vertically, so that the T-shaped rod 11 moves on the outside of the side guide sleeve 12. The bolt is inserted into the positioning hole 13 to position the T-shaped rod 11 and the side guide sleeve 12. Step 2: The operator first pulls the rubber-toothed airtight zipper 16 on the back of the rubber sleeve 1 to open the back of the rubber sleeve 1. Then, the plug housing 5 is placed directly into the inside of the rubber sleeve 1, so that the internal toothed tube 14 on the other side of the plug housing 5 passes through the rubber sleeve 1. The operator connects the rubber pad 15 through the outside of the fastener 6. Step 3: The operator attaches the rubber pad 15 to the top of the rubber sleeve 1 to prevent rainwater from seeping into the insertion part of the fastener 6. The fastener 6 is directly inserted into the inside of the internal thread tube 14 to lock the top of the rubber sleeve 1 and the plug housing 5 to prevent the plug housing 5 and the rubber sleeve 1 from shaking. At the same time, the rectangular sleeve 2 is used to cover the plug housing 5 and the electrical terminal. The operator pulls the rubber thread airtight zipper 16 in the opposite direction to seal the opening of the rubber sleeve 1. Step 4: The columnar body 3 is fixedly connected to one side of the plug housing 5 by heat pressing. The columnar body 3 is set on one side of the plug housing 5. The columnar body 3 serves as the core carrier of the conductive channel. The electrical terminals 4 installed inside it complete the transmission of current and the connection of the circuit by connecting with external wires or equipment. The rubber sleeve 1 is used to cover the plug housing 5 to prevent rainwater from seeping into the interior of the plug housing 5.

[0022] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
