[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] In the related art, the ground wire, the neutral wire and the live wire are arranged in a box. In order to prevent the ground wire from being conductive with the neutral wire and the live wire, it is necessary to set a partition or reserve a gap between the terminal connected to the ground wire and the terminal connected to the neutral wire and the live wire. As a result, not only a partition is required to separate the terminal connected to the ground wire and the terminal connected to the neutral wire and the live wire, but also a wall panel is required to surround the terminal connected to the ground wire and the terminal connected to the neutral wire and the live wire, which leads to a larger volume of the box.

[0046] In view of the above technical problems, the present application provides a wiring device. The wiring device can be used to connect a neutral wire, a live wire and / or a ground wire in a circuit connection. The wiring device uses a cavity wall forming a receiving cavity to separate a terminal connected to a ground wire and a terminal connected to a neutral wire and a live wire. In this way, the number of partitions can be reduced, which is beneficial to reducing the volume of the wiring device.

[0047] The following is combined with Figures 1 to 16 , the wiring device provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0048] Reference Figures 1 to 4 The wiring device provided in the present application includes a first housing 100, a second housing 200, a first wiring terminal 300 and a second wiring terminal 400. The first housing 100 and the second housing 200 are basic structural members, which can provide an installation basis for the first wiring terminal 300 and the second wiring terminal 400.

[0049] Exemplarily, the second housing 200 is configured to cover the first housing 100.

[0071] In the above embodiment, the second mounting hole 105 and the second wiring terminal 400 are located on the same side of the accommodating cavity, which can improve the compactness between the second mounting hole 105 and the second wiring terminal 400, thereby helping to reduce the volume of the wiring device. In some optional embodiments, the second mounting hole 105, the first connecting portion 110, and the second wiring terminal 400 are located on the same side of the accommodating cavity. In this way, sufficient space can be provided for arranging the second mounting hole 105 and the second wiring terminal 400 by simply increasing the thickness of the cavity wall on one side of the accommodating cavity adjacent to the first connecting portion 110, thereby helping to improve the compactness between the various structures in the wiring device and reduce the volume of the wiring device.

[0072] In some optional embodiments, the wiring device further includes a first seal 600 and a second seal 700. Exemplarily, the first seal 600 and the first terminal 300 are disposed in the first housing 100, and the first seal 600 surrounds the first terminal 300. The second seal 700 is disposed in the second housing 200.

[0073] In some optional embodiments, when the second shell 200 covers the first shell 100, the first sealing member 600 and the second sealing member 700 seal the gap between the first shell 100 and the second shell 200 to form a closed accommodating cavity.

[0074] Exemplarily, the first housing 100 has a receiving groove.

The first sealing member 600 is arranged along the groove wall of the receiving groove. The second sealing member 700 is arranged on one side of the second housing 200 covering the first housing 100. When the first housing 100 and the second housing 200 cover each other, the first sealing member 600 and the second sealing member 700 are stopped and sealed, and the first sealing member 600 and the first housing 100 are stopped and sealed. The second sealing member 700 and the second housing 200 are stopped and sealed, so as to seal the receiving cavity between the first housing 100 and the second housing 200 through the first sealing member 600 and the second sealing member 700 and form a sealed cavity for installing the first terminal 300.

[0075] In some optional embodiments, at least one of the first seal 600 and the second seal 700 has an elastic avoidance portion. The elastic avoidance portion can adapt to the deformation of the cable 10 and seal with the cable 10. Exemplarily, the elastic avoidance portion is supported by an elastic material so that the elastic avoidance portion can adapt to the outer peripheral wall of the cable 10 through its own elastic deformation and seal with the outer peripheral wall of the cable 10.

[0076] In some optional embodiments, the first sealing member 600 and the second sealing member 700 are both made of elastic material. For example, the material of the first sealing member 600 and the second sealing member 700 can be, but is not limited to, silicone.

[0077] In some optional embodiments, the thickness of the elastic avoidance portion is greater than or equal to the radius of the cable 10, so that the elastic avoidance portion can better adapt to the shape of the cable 10 through its own deformation, thereby allowing the first seal 600 and the second seal 700 to form a sealing surface with the cable 10 that surrounds the outer peripheral wall of the cable 10.

[0078] In some optional implementations, when the wiring device is not installed with the cable 10 and the first housing 100 and the second housing 200 are covered, the first seal 600 and the second seal 700 stop and seal, so that the wiring device can adapt to cables 10 of different diameters. Exemplarily, the maximum diameter of the cable 10 connected by the wiring device is the first diameter. In this embodiment, the wiring device can be used to connect a cable 10 with a diameter smaller than the first diameter.

[0079] The wiring device provided by the present application can utilize the extrusion force generated after the first shell 100 and the second shell 200 are covered to deform the first seal 600 and the second seal 700 under pressure and adapt to the shape of the cable 10.

[0089] Exemplarily, a second cable installation edge 710 corresponds to a first cable installation edge 610, and the second cable installation edge 710 and the first cable installation edge 610 are overlapped on both sides of the cable 10 in the direction in which the first shell 100 and the second shell 200 are covered, so that the first cable installation edge 610 and the second cable installation edge 710 can adapt to the deformation of the cable 10 and form a sealing surface around the periphery of the cable 10.

[0090] In the above embodiment, the second cable installation edge 710 is provided with the first avoidance groove 711 which is beneficial for the second cable installation edge 710 to adapt to the deformation of the cable 10 and reduces the difficulty of the second cable installation edge 710 to adapt to the deformation of the cable 10 .

[0091] Reference Figure 6 and Fig.11 In some optional embodiments, a cable groove 620 is provided on one side where the first seal 600 and the second seal 700 abut. The groove width and groove depth of the cable groove 620 are smaller than the diameter of the cable 10. For example, the specific shape of the cable groove 620 can be set as needed. Specifically, the cable groove 620 can be, but is not limited to, an arc-shaped groove. For example, the cable groove 620 can also be a V-shaped groove.

[0092] In the above embodiment, the cable groove 620 is beneficial for the first seal 600 to form a sealing surface along the outer peripheral wall of the cable 10, and the cable groove 620 is beneficial for improving the consistency of the deformation of the first seal 600 and the outer peripheral wall of the cable 10, thereby improving the sealing performance between the first seal 600 and the cable 10. In addition, the cable groove 620 can provide positioning for installing the cable 10, which is beneficial for quickly and accurately adjusting the position of the cable 10.

[0093] Reference Figure 6 and Fig.13In some optional embodiments, the second seal 700 has a second avoidance groove 720 on one side facing away from the first seal 600. When the first housing 100 and the second housing 200 are covered, the cable 10 stops at the side of the second seal 700 close to the first seal 600, and the second seal 700 can be deformed toward the notch of the second avoidance groove 720 at the bottom wall of the second avoidance groove 720.

Exemplarily, the slot width of the escape slot 107 is greater than or equal to the diameter of the cable 10. The slot depth of the escape slot 107 is greater than or equal to the radius of the cable 10.

[0106] In some embodiments, when the cable 10 includes multiple cores, the outer insulating layer of the cable 10 can be removed and then sealed with the first seal 600 and the second seal 700. Of course, the outer insulating layer of the cable 10 can also be directly sealed with the first seal 600 and the second seal 700.

[0107] Reference Figures 6 to 9 In some optional embodiments, the first housing 100 has a positioning portion 130. When the second housing 200 covers the first housing 100, the positioning portion 130 stops at the second housing 200. In this embodiment, the first housing 100 and the second housing 200 can be supported by the positioning portion 130, which is beneficial to prevent the first housing 100 and the second housing 200 from over-squeezing the first seal 600 and the second seal 700 between the first housing 100 and the second housing 200.

[0108] In some optional implementations, the first housing 100 and the second housing 200 are rotationally matched.
