Description

Technical Field

[0001] The utility model relates to the technical field of wiring cards, specifically a waterproof wiring card. Background Art

[0002] A wiring card is a device for connecting the main network without damage and insulating and protecting the parallel access points at the same time. The common wiring cards on the market usually include a bottom shell and an upper cover. There are wire clamping spring pieces for connecting wires in the bottom shell, and the upper cover is connected to the bottom shell to insulate and protect the internal access points. This kind of wiring card has a simple structure and low cost, but it does not have the waterproof function and can only be used in dry environments such as sunny days. In humid or extreme environments, there is a risk of short circuit or the circuit cannot be connected.

[0003] To avoid the above situation, some wiring cards use the method of adding silicone grease to cover the spring pieces to achieve the waterproof purpose. However, silicone grease has problems such as being sticky, polluting the workshop environment, and being inconvenient to operate during the operation. Therefore, the assembly operation is troublesome and the assembly efficiency is low. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a wiring card with simple assembly and good waterproof effect.

[0005] The technical solution of the utility model is to provide a waterproof wiring card with the following structure:

[0006] It includes a housing and a cover body; an inner cavity with an opening at the top is provided on the housing, and a wiring base is arranged in the inner cavity; one end of the cover body is hinged to the housing, and the other end is detachably connected to the housing for opening or closing the inner cavity; a sealing groove is arranged in the inner cavity along the outer edge of the wiring base in a circular distribution, a first sealing ring is arranged in the sealing groove, a first convex ring adapted to the sealing groove is arranged on the cover body, and the first convex ring is connected in the sealing groove and closely fits with the first sealing ring.

[0007] After adopting the above structure, compared with the prior art, the waterproof wiring card of the utility model has the following advantages:

[0008] The utility model sets a circular sealing groove along the outer edge of the wiring base and arranges a first sealing ring in the sealing groove. When the cover body is connected to the housing, the first convex ring will be inserted into the sealing groove and pressed on the first sealing ring, thereby playing a sealing role in the wire access points in the wiring base, ensuring the insulation of the access points and playing a role in sealing and waterproofing at the same time. This waterproof wiring card is not only simple in structure and convenient to use, but also has good waterproof performance and can still be used normally in humid or underwater environments.

[0023] As Figure 1 , Figure 2 and Figure 3 shown;

[0024] The present utility model discloses a waterproof wire clamp, which comprises a housing 1 and a cover 2. The housing 1 is provided with an inner cavity 11 with an opening at the top, and a wiring base 3 is arranged in the inner cavity 11. One end of the cover 2 is hinged to the housing 1, and the other end is detachably connected to the housing 1 for opening or closing the opening of the inner cavity 11.

[0025] A sealing groove 12 distributed annularly along the outer edge of the wiring base 3 is arranged in the inner cavity 11. A first sealing ring 4 is arranged in the sealing groove 12. The cover 2 is provided with a first convex ring 21 adapted to the sealing groove 12. The first convex ring 21 is connected in the sealing groove 12 and is in close fit with the first sealing ring 4.

[0026] By arranging an annular sealing groove 12 along the outer edge of the wiring base 3 and arranging a first sealing ring 4 in the sealing groove 12, when the cover 2 is connected to the housing 1, the first convex ring 21 will be inserted into the sealing groove 12 and pressed against the first sealing ring 4, thereby playing a sealing role in the wire access point in the wiring base 3. While ensuring the insulation of the access point, it plays a role in sealing and waterproofing. This waterproof wire clamp not only has a simple structure and is convenient to use, but also has good waterproof performance and can still be used normally in humid or underwater environments.

[0027] A connecting groove 31 is provided on the outer peripheral wall of the terminal block 3. A second sealing ring 5 is connected to the connecting groove 31. A second convex ring 22 adapted to the second sealing ring 5 is provided on the cover body 2, and the second convex ring 22 is pressed against the second sealing ring 5.

[0028] The second sealing ring 5 is arranged on the outer peripheral wall of the terminal block 3. When the cover body 2 is connected to the housing 1, the second convex ring 22 will be pressed against the second sealing ring 5, which can play a secondary sealing role for the wire access point in the terminal block 3 and ensure the sealing and waterproof effect.

[0029] The second sealing ring 5 is arranged in a U shape, and the end faces of its two free ends are attached to the inner wall of the first sealing ring 4. The free ends of the second sealing ring 5 face the end where the housing 1 and the cover body 2 are hinged.

[0030] A plurality of first lower grooves 41 are provided on the first sealing ring 4. A plurality of first upper grooves 211 that are matched and correspond one by one with the first lower grooves 41 are provided on the first convex ring 21. The first upper grooves 211 and the corresponding first lower grooves 41 enclose a first wire hole for the wire 6 to pass through.

[0031] A plurality of second lower grooves 51 are provided on the second sealing ring 5. A plurality of second upper grooves 221 that are matched and correspond one by one with the second lower grooves 51 are provided on the second convex ring 22. The second upper grooves 221 and the corresponding second lower grooves 51 enclose a second wire hole for the wire 6 to pass through.

[0032] The first wire hole and the second wire hole can prevent the first convex ring 21 and the second convex ring 22 from pressing down too much and causing damage to the insulating layer of the wire 6, thereby avoiding insulation failure.

[0033] A wire clamping spring piece 32 is provided in the terminal block 3. A wire clamping groove 321 for the wire 6 to pass through is provided on the wire clamping spring piece 32. The wire clamping groove 321 penetrates through the top of the wire clamping spring piece 32 to facilitate the wire to pass through. A plugging hole 24 corresponding to the wire clamping spring piece 32 is provided on the cover body 2. The upper end of the wire clamping spring piece 32 is plugged into the corresponding plugging hole 24, which can not only clamp the wire 6 by the wire clamping spring piece 32, but also strengthen the connection between the housing 1 and the cover body 2.

[0034] Two clamping blocks 23 are provided on the free end (i.e., the end far from the hinge axis) of the cover body 2. Corresponding clamping holes 13 corresponding to the two clamping blocks 23 are provided on the free end of the housing 1. The clamping blocks 23 are clamped in the corresponding clamping holes 13.

[0035] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
