[0038] The present application provides a junction box.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] like Figure 1-Figure 10As shown, the embodiment of the present application provides a junction box, which is connected to the cable 7 to provide power to the electrical equipment. The junction box here usually refers to the 86 box, wherein the electrical equipment can refer to wired electrical equipment, such as charging 3C products such as mobile phones and tablets through wired chargers, refrigerators, washing machines, hair dryers, vacuum cleaners, etc., and electrical equipment also includes charging 3C products such as mobile phones and tablets through wireless chargers. The junction box mainly includes a bottom shell 1, a front shell 2 and an annular waterproof part 3, and the front shell 2 is detachably connected to the bottom shell 1; the annular waterproof part 3 is arranged between the bottom shell 1 and the front shell 2. It should be noted that the annular waterproof part 3 can be a waterproof structure with a certain elasticity such as a silicone ring or a rubber ring. In this way, when the annular waterproof part 3 is arranged between the bottom shell 1 and the front shell 2, the annular waterproof part 3 can be pressed tightly to improve the waterproofness of the connection position between the bottom shell 1 and the front shell 2.

[0041] Among them, an annular groove 21 is provided along the circumference of at least one of the bottom shell 1 and the face shell 2, and an annular protrusion 11 is provided along the circumference of the other on at least the other, and the annular groove 21 is aligned with the annular protrusion 11, the annular waterproof member 3 is provided in the annular groove 21, the face shell 2 and the bottom shell 1 are connected, and the annular protrusion 11, the annular waterproof member 3 and the annular groove 21 are abutted. Exemplarily, an annular groove 21 is provided along the circumference of one of the bottom shell 1 and the face shell 2, and an annular protrusion 11 is provided along the circumference of the other on the other, and the annular waterproof member 3 is provided between the annular groove 21 and the annular protrusion 11. After the face shell 2 and the bottom shell 1 are installed together, the aligned annular protrusion 11 extends into the annular groove 21, and the annular protrusion 11 abuts the annular waterproof member 3 against the bottom wall of the annular groove 21, thereby achieving sealing of the connection position between the bottom shell 1 and the face shell 2.

[0042] In this embodiment, an optional implementation is provided, in which an annular groove 21 is provided on the surface shell 2 , and an annular protrusion 11 aligned with the annular groove 21 is provided on the bottom shell 1 .

[0043] Another optional implementation is also provided in this embodiment, in which an annular groove 21 is provided on the bottom shell 1 , and an annular protrusion 11 is provided on the surface shell 2 and is aligned with the annular groove 21 .

[0044] In this embodiment, another optional implementation is also provided, in which an annular groove 21 is provided on the surface shell 2, and an annular protrusion 11 aligned with the annular groove 21 is provided on the bottom shell 1; and an annular groove 21 is also provided on the bottom shell 1, and an annular protrusion 11 aligned with the annular groove 21 is also provided on the surface shell 2.

[0045] It should be noted that the annular groove 21 is aligned with the annular protrusion 11. The alignment means that when the surface shell 2 and the bottom shell 1 are connected together, the annular groove 21 is inserted into the inside of the annular protrusion 11, and the annular protrusion 11 and the annular groove 21 are aligned in the direction perpendicular to the connecting surface of the surface shell 2 and the bottom shell 1.

[0046] The junction box of the above structure is provided with an annular waterproof part 3 between the bottom shell 1 and the face shell 2, an annular groove 21 is provided on at least one of the bottom shell 1 and the face shell 2, and an annular protrusion 11 is provided on at least the other, and the annular groove 21 and the annular protrusion 11 are arranged in alignment, and the annular waterproof part 3 is arranged in the annular groove 21. When the face shell 2 and the bottom shell 1 are connected, the annular protrusion 11 will press the annular waterproof part 3 in the annular groove 21, thereby realizing the sealing of the bottom shell 1 and the face shell 2, thereby preventing water from entering the junction box through the gap between the bottom shell 1 and the face shell 2, thereby improving the waterproof performance of the junction box and improving the safety of the junction box.

[0047] In some embodiments, a connector 4 for connecting the bottom shell 1 and the face shell 2 is also included, and the connector 4 is arranged on the circumferential outer side of the annular waterproof member 3. Specifically, taking the annular protrusion 11 arranged on the bottom shell 1 and the annular groove 21 arranged on the face shell 2 as an example, when the bottom shell 1 and the face shell 2 need to be connected, the annular protrusion 11 of the bottom shell 1 is extended into the annular groove 21 of the face shell 2, and the annular protrusion 11 presses the annular waterproof member 3 located in the annular groove 21 tightly, and then the connector 4 is installed to achieve the connection and installation of the bottom shell 1 and the face shell 2. Further, the connector 4 is arranged on the circumferential outer side of the annular waterproof member 3, so that the annular protrusion 11 located on the circumferential inner side of the connector 4 applies an extrusion force to the annular waterproof member 3, so that the annular protrusion 11 presses the annular waterproof member 3 more tightly, so that the face shell 2 and the bottom shell 1 are connected more tightly, further avoiding the gap between the face shell 2 and the bottom shell 1, and further improving the waterproof performance between the face shell 2 and the bottom shell 1.

[0048] It should be noted that the connecting member 4 can be a connecting bolt, a buckle, a lock, or other structures.

[0049] Furthermore, in some embodiments, a plurality of connectors 4 are provided, and are evenly spaced and evenly arranged on the outer sides of the bottom shell 1 and the front shell 2, preferably, they are arranged at the four corners of the bottom shell 1 and the front shell. Such an arrangement makes the annular waterproof member 3 receive the pressure of the annular seal more evenly, which can avoid the annular seal ring receiving a small pressure at a certain position, avoid the appearance of a gap at a certain position of the front shell 2 and the bottom shell 1, further improve the sealing effect of the annular seal on the bottom shell 1 and the front shell 2, and improve the waterproof performance of the junction box.

[0050] In some embodiments, the end of the annular protrusion 11 in the protruding direction is in a constricted or serrated shape. Specifically, when the bottom shell 1 and the front shell 2 are installed together, the end of the annular protrusion 11 in the protruding direction is a constricted or serrated structure, which can apply greater pressure to the annular waterproof member 3, further squeeze the annular waterproof member 3, so that the bottom shell 1, the annular waterproof member 3 and the front shell 2 form a closed space, further improving the waterproof performance of the bottom shell 1 and the front shell 2.

[0051] In some embodiments, a wireless charging module 5 is also included, and the wireless charging module 5 includes a wireless charging base plate 51 and a wireless charging panel 52. The wireless charging base plate 51 is connected to the bottom shell 1; the wireless charging panel 52 is connected to the wireless charging base plate 51. Specifically, the wireless charging module 5 is set in the junction box, and the electrical equipment that needs wireless charging is placed on the panel of the wireless charging module 5 for wireless charging, which can quickly realize the charging of the wireless charging electrical equipment. Further, the wireless charging module 5 includes a wireless charging base plate 51 and a wireless charging panel 52. The wireless charging base plate 51 is connected to the bottom shell 1 and is electrically connected to the terminal 61 in the bottom shell 1. The wireless charging panel 52 is connected to the wireless charging base plate 51. In this way, when the bottom shell 1 and the surface shell 2 are connected through the connector 4, the bottom shell 1 and the surface shell 2 can realize the fixed installation of the wireless charging module 5, and the wireless charging panel 52 provides a charging position for the wireless charging electrical equipment.

[0052] In addition, the junction box can also provide a plug-in position for wired plugs for two-hole, three-hole, five-hole and other sockets.

[0053] In some embodiments, a clearance hole 22 for avoiding the wireless charging panel 52 is provided on the face shell 2, and the end surfaces of the wireless charging panel 52 and the face shell 2 away from the bottom shell 1 are substantially flush. Specifically, after the cable 7 is connected to the terminal 61, the wireless charging base plate 51 of the wireless charging module 5 is connected to the bottom shell 1, and then the bottom shell 1 with the wireless charging module 5 installed is connected to the face shell 2 through the connector 4, and a clearance hole 22 for avoiding the wireless charging panel 52 is provided on the face shell 2, and the end surfaces of the wireless charging panel 52 and the face shell 2 away from the bottom shell 1 are substantially flush, and the bottom shell 1 and the face shell 2 are connected, thereby locking the wireless charging module 5. Ensuring that the end surfaces of the wireless charging panel 52 and the face shell 2 away from the bottom shell 1 are substantially flush can facilitate the placement of the wireless charging device during charging and improve the stability of the placement.

[0054] It should be noted that the end surfaces of the wireless charging panel 52 and the surface shell 2 away from the bottom shell 1 are basically flush. Basically flush means that the two are in the same plane or there is a slight height difference between the two. When the wireless charging device to be charged is placed on the wireless charging panel 52, the stability of the wireless charging panel 52 and the surface shell 2 can also be guaranteed.

[0055] In some embodiments, a terminal assembly 6 is included, and the terminal assembly 6 includes a terminal 61 and a locking member 62. The terminal 61 is connected to the cable 7 to realize the electrical connection between the cable 7 and the junction box, wherein: the terminal 61 is provided with a first groove 611 and a second groove 612 that are connected to each other, and the first groove 611 and the second groove 612 are arranged in different directions; the cable 7 is arranged in the first groove 611 and the second groove 612. It should be noted that the locking member 62 can be a locking screw or a spring. Exemplarily, the locking member 62 is a locking screw. Taking the cable 7 being arranged in the first groove 611 and the locking member 62 being arranged in the second groove 612 as an example, when the locking member 62 is a locking screw, an internal thread is arranged on the inner wall of the second groove 612, so that when the cable 7 is placed in the first groove 611, the locking screw is rotated to realize the locking of the cable 7. With such a configuration, the cable 7 can be locked quickly, and the locking effect is good, so that the cable 7 and the terminal 61 are firmly connected.

[0056] It should also be noted that the arrangement of the first groove 611 and the second groove 612 is not limited. The cable 7 is arranged in the first groove 611, and correspondingly, the locking member 62 is arranged in the second groove 612; the cable 7 is arranged in the second groove 612, and correspondingly, the locking member 62 is arranged in the first groove 611.

[0057] It should also be noted that the terminal 61 is usually a copper terminal, and the junction box is usually an 86 box.

[0058] The terminal assembly 6 of the above structure has a first groove 611 and a second groove 612 that are connected to each other, and the first groove 611 and the second groove 612 are arranged in different directions, so that when water enters the terminal 61, the water will flow into one of the grooves and then flow out of the other groove, and the first groove 611 and the second groove 612 can play a role in drainage. The cable 7 is arranged in one of the first groove 611 and the second groove 612, and the locking member 62 is arranged in the other, so that the electrical connection between the cable 7 and the terminal 61 can be easily achieved, and the wiring efficiency is improved.

[0059] In some embodiments, the first groove 611 is opened along the first direction, the second groove 612 is opened along the second direction, and the angle between the first direction and the second direction is 60° to 120°. Specifically, ensuring that the angle between the first direction and the second direction is within the above range can increase the locking force applied by the locking member 62 to the cable 7 and the terminal 61, improve the stability of the connection between the cable 7 and the terminal 61, and prevent the cable 7 from moving out of the terminal 61.

[0060] Illustratively, the angle between the first direction and the second direction may be: 60°, 70°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, etc.

[0061] In some embodiments, the angle between the first direction and the second direction is ensured to be 95°, so that when water flows into the first groove 611 of the terminal 61, the water can quickly flow out from the second groove 612 to increase the water outflow speed and avoid water retention in the terminal 61, thereby reducing the probability of ignition short circuit and improving the safety of the junction box when in use; and the angle between the first direction and the second direction is within the above range, while increasing the water outflow speed, it can ensure the locking effect of the locking member 62 on the cable 7, thereby improving the stability of the connection between the cable 7 and the terminal 61.

[0062] In addition, the angle between the first direction and the second direction can also be greater than 90° and less than or equal to 150°, so that when water enters from the first groove 611, since the angle between the first direction and the second direction is greater than 90°, the water can quickly flow out from the second groove 612 to avoid water remaining in the terminal 61.

[0063] Here, the first direction and the second direction are not limited. For example, the first direction is Figure 7 The first direction is the direction indicated by the double-headed arrow Y, and the second direction is the direction indicated by the double-headed arrow X. At this time, the angle between the first direction and the second direction is 95°.

[0064] In some embodiments, the terminal 61 is integrally formed with the bottom shell 1. Specifically, the terminal 61 and the bottom shell 1 are integrally injection molded, so that there is no gap between the terminal 61 and the bottom shell 1, and water is not easy to flow into the junction box from between the terminal 61 and the bottom shell 1, thereby improving the waterproofness of the junction box, avoiding sparks or short circuits caused by moisture or water ingress, and improving the safety of the junction box when in use.
