DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0039] 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.

[0040] In the related art, in order to achieve waterproof sealing during the wiring process of the junction box, it is necessary to drill holes on the shell and then install cable sealing joints to achieve sealing between the cables and the holes on the shell through the cable sealing joints. Although this can achieve sealing between the cables and the shell, the operation is cumbersome and not conducive to rapid operation. In addition, during the drilling process, the hole size needs to be adapted to the cable sealing joint, otherwise the seal between the cable sealing joint and the shell is prone to failure, thereby affecting the sealing performance.

[0041] The following is combined with Figures 1 to 11 , the wiring device provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0042] Reference Figure 1 The wiring device includes a first housing 100, a second housing 200, a first seal 300, a second seal 400 and a wiring terminal 500. The first housing 100 and the second housing 200 are basic structural parts, which can provide an installation basis for the first seal 300, the second seal 400 and the wiring terminal 500.

[0043] Exemplarily, the first seal 300 and the terminal 500 are disposed on the first housing 100, and the first seal 300 surrounds the terminal 500. The second seal 400 is disposed on the second housing 200. The second housing 200 is configured to cover the first housing 100. The terminal 500 is used to connect the cable 600. Exemplarily, the cable 600 in the external circuit can be electrically connected through the terminal 500.

[0044] In some optional embodiments, when the second housing 200 covers the first housing 100, the first seal 300 and the second seal 400 are sealed together, and the first housing 100, the first seal 300, the second housing 200 and the second seal 400 enclose a sealed cavity. The connection terminal 500 is located in the sealed cavity.

[0045] Exemplarily, the first housing 100 has a receiving groove. The second housing 200 covers the notch of the receiving groove so that a receiving cavity can be formed between the first housing 100 and the second housing 200. The first seal 300 is arranged along the groove wall of the receiving groove. The second seal 400 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, the first seal 300 and the second seal 400 are stopped and sealed, and the first seal 300 and the first housing 100 are stopped and sealed. The second seal 400 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 seal 300 and the second seal 400 and form a sealed cavity for installing the terminal 500.

[0046] In some optional embodiments, at least one of the first seal 300 and the second seal 400 has an elastic avoidance portion. The elastic avoidance portion can adapt to the deformation of the cable 600 and seal with the cable 600. 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 600 through its own elastic deformation and seal with the outer peripheral wall of the cable 600.

[0047] In some optional embodiments, the first sealing member 300 and the second sealing member 400 are both made of elastic material. For example, the material of the first sealing member 300 and the second sealing member 400 can be, but is not limited to, silicone.

[0048] In some optional embodiments, the thickness of the elastic avoidance portion is greater than or equal to the radius of the cable 600, so that the elastic avoidance portion can better adapt to the shape of the cable 600 through its own deformation, thereby allowing the first seal 300 and the second seal 400 to form a sealing surface with the cable 600 that surrounds the outer peripheral wall of the cable 600.

[0049] In some optional implementations, when the wiring device is not installed with the cable 600 and the first housing 100 and the second housing 200 are covered, the first seal 300 and the second seal 400 are stopped and sealed, so that the wiring device can adapt to cables 600 of different diameters. Exemplarily, the maximum diameter of the cable 600 connected by the wiring device is the first diameter. In this embodiment, the wiring device can be used to connect a cable 600 with a diameter smaller than the first diameter.

[0050] The wiring device provided by the present application can utilize the extrusion force generated after the first housing 100 and the second housing 200 are covered to deform the first seal 300 and the second seal 400 under pressure and adapt to the shape of the cable 600. This is not only beneficial to reduce the wiring difficulty and improve the wiring efficiency, but also beneficial to improve the sealing performance of the wiring point, avoid the external fluid from contacting the wiring point of the cable 600, and achieve the purpose of protecting the wiring point of the cable 600. In addition, the wiring device provided by the present application is also convenient for disconnecting the wiring point of the cable 600 to facilitate circuit maintenance.

[0051] In some optional embodiments, there are many ways to connect the first sealing member 300 to the first housing 100. For example, the first sealing member 300 and the first housing 100 can be connected by, but not limited to, bonding, buckling, pressing, and the like.

[0052] In some optional embodiments, such as Figure 1 and Figure 3 As shown, at least a portion of the first seal 300 protrudes from the surface of the first housing 100 and the second housing 200. At least a portion of the first seal 300 protrudes from the first housing 100, which is beneficial to ensure that the first seal 300 and the second housing 200 and / or the second seal 400 are sealed against each other. In addition, at least a portion of the first seal 300 protruding from the first housing 100 is also beneficial to increase the maximum deformation of the first seal 300 in the covering direction of the first housing 100 and the second housing 200, thereby adapting to a cable 600 with a larger diameter.

[0053] In some optional embodiments, the portion of the first sealing member 300 that protrudes from the mating surface of the first housing 100 and the second housing 200 surrounds the connection terminal 500 to form a sealed cavity for accommodating the connection terminal 500 .

[0054] In some optional embodiments, such as Figure 1and Figure 3 As shown, at least part of the second seal 400 protrudes from the surface of the second housing 200 and the first housing 100. This is beneficial to the stop seal between the second seal 400 and the first seal 300, and is also beneficial to increase the maximum deformation of the second seal 400 in the covering direction of the first housing 100 and the second housing 200, thereby adapting to the cable 600 with a larger diameter.

[0055] In some optional embodiments, the portion of the second sealing member 400 that protrudes from the mating surface of the first housing 100 and the second housing 200 surrounds the connection terminal 500 to form a sealed cavity for accommodating the connection terminal 500 .

[0056] In some optional embodiments, the first seal 300 protrudes from the surface of the first housing 100 and the second housing 200. The second seal 400 protrudes from the surface of the second housing 200 and the first housing 100. This is beneficial to ensure that the first seal 300 and the second seal 400 form a sealing surface surrounding the wiring terminal 500, thereby improving the sealing performance of the wiring device. In addition, in this embodiment, the first seal 300 and the second seal 400 are also beneficial to increase the avoidance gap between the first housing 100 and the second housing 200 to avoid the cable 600, and the spacing between the first seal 300 and the second seal 400 can be adjusted according to the elastic deformation of the first seal 300 and the second seal 400, thereby adapting to cables 600 of different diameters.

[0057] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 In some optional embodiments, the first seal 300 has a first cable installation edge 310. Exemplarily, the first cable installation edge 310 is a side of the first seal 300 used to install the cable 600 and seal with the outer peripheral wall of the cable 600. In some optional embodiments, the side of the first cable installation edge 310 that seals with the second seal 400 has an arc-shaped protrusion 311 to form an elastic avoidance portion. In some optional embodiments, the first seal 300 has two first cable installation edges 310. Exemplarily, the two first cable installation edges 310 are arranged on opposite sides of the terminal block 500.

[0058] In the above embodiment, the first cable installation edge 310 is provided with an arc-shaped protrusion 311 to increase the thickness of the first cable installation edge 310, thereby being beneficial to increasing the ability of the first cable installation edge 310 to adapt to the deformation of the cable 600, so as to adapt to cables 600 of different diameters. In addition, the first cable installation edge 310 is provided with an arc-shaped protrusion 311, which is beneficial to make the first cable installation edge 310 deform to cover the cable 600 installed on the first cable installation edge 310, thereby improving the sealing performance between the wiring device and the cable 600.

[0059] When the first housing 100 and the second housing 200 are covered, the arc-shaped protrusion 311 is beneficial to transfer the force of the first housing 100 and the second housing 200 acting on the first seal 300 and the second seal 400 to the first cable installation edge 310, thereby improving the sealing performance between the first seal 300 and the cable 600. In addition, when the diameters of the installed cables 600 are equal, the provision of the arc-shaped protrusion 311 is beneficial to reducing the resistance of the first housing 100 and the second housing 200 covering each other, thereby reducing the wiring difficulty of the wiring device.

[0060] Reference Figure 3 and Fig.10 In some optional embodiments, the second sealing member 400 has a second cable installation edge 410. Exemplarily, the second cable installation edge 410 is an edge of the second sealing member 400 for installing the cable 600 and sealing with the outer peripheral wall of the cable 600. Exemplarily, a first avoidance groove 411 is provided on one side of the second cable installation edge 410 that is sealed with the first sealing member 300. The first avoidance groove 411 is provided along the extension direction of the second cable installation edge 410 to form an elastic avoidance portion.

[0061] Exemplarily, a second cable installation edge 410 corresponds to a first cable installation edge 310, and the second cable installation edge 410 and the first cable installation edge 310 are overlapped on both sides of the cable 600 in the direction in which the first shell 100 and the second shell 200 are covered, so that the first cable installation edge 310 and the second cable installation edge 410 can adapt to the deformation of the cable 600 and form a sealing surface around the periphery of the cable 600.

[0062] In the above embodiment, the second cable installation edge 410 is provided with the first avoidance groove 411 which is beneficial for the second cable installation edge 410 to adapt to the deformation of the cable 600 and reduces the difficulty of the second cable installation edge 410 to adapt to the deformation of the cable 600 .

[0063] Reference Figure 1 and Figure 6In some optional embodiments, a cable groove 320 is provided on one side where the first seal 300 and the second seal 400 abut. The groove width and groove depth of the cable groove 320 are smaller than the diameter of the cable 600. For example, the specific shape of the cable groove 320 can be set as needed. Specifically, the cable groove 320 can be, but is not limited to, an arc-shaped groove. For example, the cable groove 320 can also be a V-shaped groove.

[0064] In the above embodiment, the cable groove 320 is beneficial for the first seal 300 to form a sealing surface along the outer peripheral wall of the cable 600, and the cable groove 320 is beneficial for improving the consistency of the deformation of the first seal 300 and the outer peripheral wall of the cable 600, thereby improving the sealing performance between the first seal 300 and the cable 600. In addition, the cable groove 320 can provide positioning for installing the cable 600, which is beneficial for quickly and accurately adjusting the position of the cable 600.

[0065] Reference Figure 1 and Figure 8 In some optional embodiments, the second seal 400 has a second avoidance groove 420 on one side facing away from the first seal 300. When the first shell 100 and the second shell 200 are covered, the cable 600 stops at the side of the second seal 400 close to the first seal 300, and the second seal 400 can be deformed toward the notch of the second avoidance groove 420 at the bottom wall of the second avoidance groove 420. Exemplarily, the specific shape of the second avoidance groove 420 can be set as needed. Specifically, the second avoidance groove 420 can be, but is not limited to, an arc-shaped groove. Exemplarily, the cable groove 320 can also be a V-shaped groove.

[0066] In the above embodiment, the second avoidance groove 420 is helpful to reduce the difficulty of the second seal 400 to adapt to the deformation of the cable 600. In addition, the second avoidance groove 420 is arranged on the side of the second seal 400 away from the first seal 300. In the process of covering the first shell 100 and the second shell 200, the side of the second seal 400 close to the first seal 300 stops at the cable 600 and deforms under the pressure of the cable 600, which is helpful to improve the tightness of the second seal 400 and the cable 600.

[0067] Exemplarily, the part where the second seal 400 and the cable 600 abut against each other is opposite to the second avoidance groove 420. In this way, when the second seal 400 is squeezed by the cable 600, the second seal 400 is recessed toward the notch of the second avoidance groove 420, which is beneficial to form a groove adapted to the cable 600 on the side of the second seal 400 close to the first seal 300, and seal with the cable 600.

[0068] In the above embodiment, the second avoidance groove 420 is located on the side of the second seal 400 away from the first seal 300. In this way, not only can the second avoidance groove 420 be used to reduce the elastic force exerted on the groove of the cable 600 by squeezing the second seal 400 to deform, but also the side of the second seal 400 close to the first seal 300 can accommodate cables 600 of more diameters.

[0069] In some optional embodiments, such as Figure 2 and Figure 4 As shown, the first housing 100 has a first mounting groove 110 and a terminal mounting portion 120. The first mounting groove 110 is arranged around the wiring terminal 500, and the bottom of the first mounting groove 110 is sunken into the terminal mounting portion 120. The wiring terminal 500 is arranged in the terminal mounting portion 120, and at least part of the first sealing member 300 is located in the first mounting groove 110. Exemplarily, the first sealing member 300 is sealed with the bottom and / or wall of the first mounting groove 110.

[0070] In some optional embodiments, the first seal 300 is embedded in the first mounting groove 110. Exemplarily, the first seal 300 can be interference fit with the first mounting groove 110, thereby improving the sealing between the first seal 300 and the first housing 100 and preventing the first seal 300 from falling off from the first mounting groove 110. In addition, the first mounting groove 110 can restrict the deformation of the first seal 300, which is beneficial for the first seal 300 to deform according to a preset shape and improve the sealing performance of the wiring device.

[0071] Reference Figures 1 to 4 as well as Fig.11 As shown, in some optional embodiments, the connection terminal 500 includes a plurality of groups of connection terminals 510 arranged at intervals. For example, the number of the connection terminals 500 can be set as needed. For this reason, the specific number of the connection terminals 500 is not limited in this embodiment.

In some optional embodiments, the mounting protrusion 210 has an avoidance notch 211. Exemplarily, the avoidance notch 211 is opposite to the portion of the second sealing member 400 that stops abutting against the cable 600, which is beneficial to the deformation of the second sealing member 400 under the extrusion of the cable 600, and reduces the difficulty of sealing the second sealing member 400 with the cable 600.

[0076] Reference Figure 4 In some optional embodiments, a side of the second housing 200 corresponding to the elastic avoidance portion has a third mounting groove 220.

When the first housing 100 and the second housing 200 are covered, the escape slot 130 forms a wire-passing channel for installing the cable 600. Exemplarily, the slot width of the escape slot 130 is greater than or equal to the diameter of the cable 600. The slot depth of the escape slot 130 is greater than or equal to the radius of the cable 600.

[0078] In some embodiments, when the cable 600 includes multiple cores, the outer insulating layer of the cable 600 can be removed and then sealed with the first seal 300 and the second seal 400. Of course, the outer insulating layer of the cable 600 can also be directly sealed with the first seal 300 and the second seal 400.

[0079] Reference Figures 1 to 4 In some optional embodiments, the first housing 100 has a positioning portion 140. When the second housing 200 covers the first housing 100, the positioning portion 140 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 140, which is beneficial to prevent the first housing 100 and the second housing 200 from over-squeezing the first seal 300 and the second seal 400 between the first housing 100 and the second housing 200.

[0080] In some optional implementations, the first housing 100 and the second housing 200 are rotationally matched. When the first housing 100 and the second housing 200 are covered, the first housing 100 is configured to lock with the second housing 200 and maintain the first housing 100 and the second housing 200 covered. Exemplarily, one of the first housing 100 and the second housing 200 is provided with a first buckle portion, and the other is provided with a second buckle portion. When the first housing 100 and the second housing 200 are covered, the first buckle portion and the second buckle portion are buckled. Exemplarily, one of the first buckle portion and the second buckle portion is a groove, and the other is a protrusion.

[0081] In some other optional embodiments, the first housing 100 and the second housing 200 can also be locked by screws to maintain the first housing 100 and the second housing 200 covering each other. In some optional embodiments, the first housing 100 and the second housing 200 can also be locked by screws for installing the wiring device to maintain the first housing 100 and the second housing 200 covering each other. Of course, there are many ways to lock the first housing 100 and the second housing 200. This embodiment does not limit the specific way in which the first housing 100 and the second housing 200 are locked to maintain the first housing 100 and the second housing 200 covering each other.

[0082] Reference Figure 3 and Figure 4 According to some optional embodiments, the wiring device further includes a rotating shaft 700. The first housing 100 and the second housing 200 are both provided with a hinge hole 170. The rotating shaft 700 is provided in the hinge hole 170, and the first housing 100 and the second housing 200 are rotatably matched through the rotating shaft 700.

[0083] In the above embodiment, the first housing 100 and the second housing 200 are rotationally matched. During the wiring operation, there is no need to align the first housing 100 and the second housing 200. Directly rotating one of them can achieve the alignment and covering of the first housing 100 and the second housing 200. Therefore, in the above embodiment, the rotational matching of the first housing 100 and the second housing 200 is beneficial to reducing the wiring difficulty and improving the assembly accuracy of the first housing 100 and the second housing 200, so as to avoid excessive assembly errors affecting the waterproof performance of the wiring device.

[0084] In some optional embodiments, at least one of the first shell 100 and the second shell 200 is provided with an expanded hole area. The expanded hole area is located on one side of the hinge hole 170 in the direction of covering the first shell 100 and the second shell 200, so as to increase the spacing between the first shell 100 and the second shell 200 after covering by expanding the hinge hole 170 toward the expanded hole area. Exemplarily, by reserving the expanded hole area on the first shell 100 or the second shell 200, during the wiring operation, the hinge hole 170 can be expanded to increase the avoidance gap between the first shell 100 and the second shell 200 to accommodate a cable 600 with a larger diameter.

[0085] In some other optional embodiments, at least one of the first housing 100 and the second housing 200 has two sets of hinge holes 170, and the two sets of hinge holes 170 are arranged along the covering direction of the first housing 100 and the second housing 200. The rotating shaft 700 is installed in one set of hinge holes 170. In the above embodiment, the rotating shaft 700 can be installed in different hinge holes 170 according to the size of the cable 600 to adapt to cables 600 of different diameters, so that the wiring device can be applicable to cables 600 within a wider range of sizes.
