Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0026] The following is combined Figures 1-14 Specific embodiments of the present invention are described below.

[0027] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a tension-resistant and waterproof connector, which includes a threaded plug 100, a connector seat 200, and a sealing ring 300. Both the threaded plug 100 and the connector seat 200 are sleeve-type structures, through which a cable 400 can be threaded. The sealing ring 300 is located between the two to seal the surface of the cable 400.

[0028] like Figure 1As shown, in this embodiment, the threaded plug 100 has a first wire hole 110 that extends through it along its axial direction. The inner diameter of the first wire hole 110 is slightly larger than the diameter of the cable 400 so that the cable 400 can pass through it. A first external thread 120 is provided on the surface of the threaded plug 100. The first external thread 120 extends and protrudes to one side of the threaded plug 100 along its axial direction for connection with the connector seat 200.

[0029] like Figure 1 As shown, the connector 200 has a second wire hole 210 that extends through it along its axial direction. Similar to the first wire hole 110, the inner diameter of the second wire hole 210 is also slightly larger than the diameter of the cable 400 so that the cable 400 can pass through it. The second wire hole 210 and the first wire hole 110 are coaxially arranged so that the same cable 400 can pass through both at the same time.

[0030] A threaded hole is provided at one end of the connector seat 200. The threaded hole has a first internal thread 220. The threaded hole with the first internal thread 220 is connected to the second wire hole 210. The threaded hole and the second wire hole 210 are coaxially arranged. The size of the threaded hole corresponds to the first external thread 120 so that the threaded plug 100 can be connected to the connector seat 200 through the engagement of the first external thread 120 and the first internal thread 220.

[0031] In this embodiment, the sealing ring 300 is located at the bottom of the threaded hole of the first internal thread 220. In use, the connector 200 is connected to the lamp housing 500, and the cable 400 is sequentially passed through the first wire hole 110, the sealing ring 300, and the second wire hole 210 to connect into the lamp housing 500. The threaded plug 100 is then tightened. The threaded plug 100 is tightened inside the connector 200, squeezing the sealing ring 300. The sealing ring 300 is elastic, and under the compression of the threaded plug 100, the sealing ring 300 abuts against the connector 200 and the cable 400, eliminating the gap on the surface of the cable 400, thereby achieving a waterproof function.

[0032] The embodiments of the present invention achieve effective waterproofing of the connector through the cooperation of the threaded plug 100, the connector seat 200 and the sealing ring 300, thereby improving the adaptability of the lamp to outdoor environments.

[0033] Meanwhile, the threaded connection between the threaded plug 100 and the connector seat 200 improves the connection strength of the connector. This connector wraps around the cable 400, effectively protecting it and preventing damage at the connection point between the cable 400 and the lamp housing 500. It also reduces the impact of cable 400 being pulled or bent, increasing the tensile strength at the connection point and thus extending the lifespan of the lamp. Figure 13 and Figure 14 .

[0034] Furthermore, the anti-pull and waterproof connector provided in this embodiment has a simple overall structure, consisting of only three parts: threaded plug 100, connector seat 200, and sealing ring 300. It has low cost, is easy to assemble and operate, and can achieve rapid assembly to meet the installation requirements of outdoor lighting fixtures.

[0035] like Figure 1 As shown, in this embodiment, an annular boss 260 is provided at the bottom of the threaded hole of the first internal thread 220. After installation, one side of the sealing ring 300 abuts against the annular boss 260, and the other side of the sealing ring 300 abuts against the threaded plug 100. The annular boss 260 effectively supports the sealing ring 300, improving the installation stability of the sealing ring 300.

[0036] In some embodiments, combined with Figures 2 to 5 As shown, the threaded plug 100 can be divided into two parts, including a first plug body 101 and a second plug body 102. The first plug body 101 and the second plug body 102 are arranged opposite each other along the central axis of the threaded plug 100. That is, the first plug body 101 and the second plug body 102 are two parts of the threaded plug 100 cut along its axis to cut open the first wire hole 110. The first plug body 101 and the second plug body 102 are arranged opposite each other along the central axis of the threaded plug 100, and the first plug body 101 and the second plug body 102 are seamlessly spliced ​​together.

[0037] The threaded plug 100 consists of two disassembled parts. During installation, the threaded plug 100 can be disassembled, the cable 400 can be directly inserted into the first wire hole 110, and then the first plug body 101 and the second plug body 102 can be merged to achieve quick wire threading. This solution is particularly suitable for cases where the cable 400 is long, enabling quick connector installation and improving work efficiency.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, in one embodiment, the first plug 101 and the second plug 102 are flexibly connected by a flexible connecting part, wherein the flexible connecting part may be a connecting rib 103 or a connecting piece, and the threaded plug 100 may be integrally formed of plastic material. In order to facilitate manufacturing and processing, the flexible connecting part may be integrally formed with the threaded plug 100.

[0039] In some embodiments, it is foreseeable that the first plug 101 and the second plug 102 may also be pivotally or hinged using a pivot structure or a rotating shaft structure, without any specific limitation.

[0040] For example, the first plug 101 and the second plug 102 are connected by a rotating shaft, the axis of which is parallel to the axis of the threaded plug 100. In this way, the threaded plug 100 can be rotated open to complete the quick wiring.

[0041] In one embodiment, one end of the first plug 101 and the second plug 102 are connected by a pivot, and the other end can be provided with a corresponding snap-fit ​​structure. When the first plug 101 and the second plug 102 are combined, they are locked by the snap-fit ​​structure.

[0042] like Figure 5 and 6 As shown, in one embodiment, the first plug 101 and the second plug 102 are two independent structures. The first plug 101 and the second plug 102 are respectively provided with opposite buckles 104, and the first plug 101 and the second plug 102 are engaged by the buckles 104.

[0043] In one embodiment, the first plug 101 and the second plug 102 may be made of plastic material. The lightweight threaded plug 100 is easy to install and use, reducing costs.

[0044] like Figures 7-9 As shown, in one embodiment, the sealing ring 300 has an opening 301 on its sidewall that is opened along its axial direction to cut the sealing ring 300, so that the sealing ring 300 is an open ring with an opening.

[0045] Because the sealing ring 300 is elastic, the cable 400 can be directly inserted into the sealing ring 300 through the opening 301, so that the sealing ring 300 can be quickly fitted onto the cable 400. This is especially suitable for situations where the cable 400 is too long, enabling rapid installation.

[0046] like Figure 8 and Figure 9 As shown, the opening 301 of the sealing ring 300 can be set at an angle, so that when the sealing ring 300 is compressed, the opening 301 can be better closed, thus improving the sealing effect.

[0047] The sealing ring 300 in this embodiment can be configured with different shapes.

[0048] like Figure 7 and Figure 8 As shown, a first embodiment of a sealing ring 300 is provided. The sealing ring 300 has a rectangular cross-section. The surface of the rectangular sealing ring 300 can fully contact the threaded plug 100 and the connector seat 200 to improve the sealing performance.

[0049] like Figure 9 and Figure 10 As shown, a second embodiment of a sealing ring 300 is provided, wherein the sealing ring 300 has a tapered cross-section.

[0050] In this embodiment, the bottom of the threaded hole of the first internal thread 220 is a tapered surface, and the sealing ring 300 is a tapered ring corresponding to the tapered surface. The tapered ring increases the contact area between the sealing ring 300 and the connector seat 200, thereby improving the waterproof effect.

[0051] like Figure 11 and Figure 12 As shown, a third embodiment of a sealing ring 300 is provided, wherein the sealing ring 300 has a circular cross-section.

[0052] In this embodiment, the sealing ring 300 can have greater elasticity. Under the compression of the threaded plug 100, the sealing ring 300 deforms and fully contacts the cable 400 and the connector seat 200, thereby improving the waterproof performance of the connector.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, the connector 200 has a connecting portion 230 at the other end of the threaded hole of the first internal thread 220. The surface of the connecting portion 230 is provided with a second external thread 240. Since the connector 200 is to be connected to the lamp housing 500, a second internal thread corresponding to the second external thread 240 can be provided on the surface of the lamp housing 500. The connector 200 can be connected to the lamp housing 500 through the second external thread 240 to achieve a detachable connection of the connector.

[0054] Furthermore, an annular flange 270 is provided on the surface of the connector 200 near the connecting part 230. The side surface of the annular flange 270 facing the connecting part 230 is the abutting surface. A washer 250 is fitted on the end face of the connector 200 outside the connecting part 230. The washer 250 abuts against the abutting surface of the annular flange 270. When the connector is installed, the washer 250 abuts between the annular flange 270 of the connector 200 and the lamp housing 500, thereby improving the waterproof performance of the connector connection.

[0055] like Figure 13 As shown, an embodiment of the present invention provides a lighting fixture, which includes a fixture housing 500, a light source module 600, and a cable 400. The cable 400 is externally connected to the light source module 600 inside the fixture housing 500.

[0056] In this embodiment, a mounting portion 510 is provided at the wiring terminal of the lamp housing 500. The mounting portion 510 has a threaded hole structure and is connected to the mounting portion 510 via a connector with a second external thread 240, as mentioned in the above embodiment. The connector seat 200 is detachably connected to the mounting portion 510 via the second external thread 240. The cable 400 passes sequentially through the threaded plug 100, the sealing ring 300, and the connector seat 200 to connect to the light source module 600. Because this lighting fixture is equipped with the anti-pull and waterproof connector described in the above embodiment, it also possesses all the advantages of the above embodiments.

[0057] like Figure 14As shown, this embodiment of the invention also provides a lighting fixture, which is an improvement over the lighting fixture of the above embodiment.

[0058] Similar to the above embodiments, the lighting fixture in this embodiment includes a fixture housing 500, a light source module 600, and a cable 400. The cable 400 is externally connected to the light source module 600 inside the fixture housing 500.

[0059] The difference is that, in this embodiment, the lamp housing 500 is provided with a mounting part 510, and the connector seat 200 of the connector is integrated with the lamp housing 500 to replace the function of the aforementioned mounting part 510.

[0060] Specifically, the connector 200 is integrally formed with the lamp housing 500, and the cable 400 passes through the threaded plug 100, the sealing ring 300, and the connector 200 in sequence to connect to the light source module 600. In this embodiment, the connector 200 does not need to be disassembled. During installation, simply pass the cable 400 through the threaded plug 100 and the sealing ring 300, and then screw the threaded plug 100 directly into the first internal thread 220 on the lamp housing 500 to achieve quick installation.

[0061] Therefore, this embodiment not only has the advantage of faster installation, but also possesses all the advantages of the embodiments described above.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
