[0028] The present application provides a terminal assembly and a junction box including the terminal assembly.

[0029] 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.

[0030] like Figure 1-Figure 6 As shown, an embodiment of the present application provides a terminal assembly 1, which is a component of a junction box, and a terminal 11 is connected to a cable 4, so as to realize an electrical connection between the cable 4 and the junction box. The terminal assembly 1 is arranged in the junction box, and the terminal assembly 1 mainly includes a terminal 11 and a locking member 12, and the terminal 11 is connected to the cable 4 to realize an electrical connection between the cable 4 and the junction box. The terminal 11 is electrically connected to the cable 4, and the locking member 12 is used to lock the terminal 11 and the cable 4 to realize an electrical connection between the terminal 11 and the cable 4, so as to realize an electrical connection between the cable 4 and the junction box.

[0031] The terminal 11 is provided with a first slot 111 and a second slot 112 which are connected to each other, and the first slot 111 and the second slot 112 are arranged in different directions; the cable 4 is arranged in one of the first slot 111 and the second slot 112, and the locking member 12 is arranged in the other one to lock the cable 4 with the terminal 11. Here, the arrangement directions of the first slot 111 and the second slot 112 are not limited, and it is only necessary to ensure that the arrangement directions of the first slot 111 and the second slot 112 are different, so that the locking member 12 can lock the cable 4.

[0032] It should be noted that the locking member 12 may be a locking screw or a spring, etc. For example, taking the locking member 12 as a locking screw, the cable 4 is arranged in the first groove 111, and the locking member 12 is arranged in the second groove 112 as an example, when the locking member 12 is a locking screw, an internal thread adapted to the locking screw is arranged on the inner wall of the second groove 112, so that after the cable 4 is placed in the first groove 111, the locking screw is rotated to lock the cable 4. With such a configuration, the cable 4 can be locked quickly, and the locking effect is good, so that the cable 4 and the terminal 11 are firmly connected.

[0033] It should also be noted that the arrangement of the first groove 111 and the second groove 112 is not limited. The cable 4 is arranged in the first groove 111, and correspondingly, the locking member 12 is arranged in the second groove 112; the cable 4 is arranged in the second groove 112, and correspondingly, the locking member 12 is arranged in the first groove 111.

[0034] It should also be noted that the terminal 11 is usually a copper terminal 11, and the junction box is usually an 86 box.

[0035] The terminal assembly 1 of the above structure has a first groove 111 and a second groove 112 that are connected to each other in the terminal 11, and the first groove 111 and the second groove 112 are arranged in different directions, so that when water enters the terminal 11, the water will flow into one of the grooves and flow out from the other groove, and the first groove 111 and the second groove 112 can also play a role in drainage. In addition, the cable 4 is arranged in one of the first groove 111 and the second groove 112, and the locking member 12 is arranged in the other, so that it is easy to achieve electrical connection between the cable 4 and the terminal 11, and improve wiring efficiency.

[0036] In some embodiments, the first groove 111 is opened along the first direction, the second groove 112 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 12 to the cable 4 and the terminal 11, improve the stability of the connection between the cable 4 and the terminal 11, and prevent the cable 4 from moving out of the terminal 11.

[0037] 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.

[0038] 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 111 of the terminal 11, the water can quickly flow out from the second groove 112 to increase the water outflow speed and avoid water retention in the terminal 11, thereby reducing or even avoiding 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 also improve the locking effect of the locking member 12 on the cable 4 and improve the stability of the connection between the cable 4 and the terminal 11.

[0039] 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°. In this way, when water enters from the first groove 111, 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 112, avoiding water from remaining in the terminal 11, thereby improving the safety of the junction box when in use.

[0040] Here, the first direction and the second direction are not limited. For example, the first direction is Figure 3 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°.

[0041] Furthermore, in some embodiments, one end of the first groove 111 overlaps with one end of the second groove 112. In this way, when the cable 4 is placed in the first groove 111, the cable 4 is moved to the overlapping area of ​​the first groove 111 and the second groove 112, and then the locking member 12 is placed in the second groove 112, so as to lock the cable 4 and the terminal 11 in the overlapping area of ​​the first groove 111 and the second groove 112, the convenience of locking the cable 4 by the locking member 12 can be improved, and the stability of the connection between the cable 4 and the terminal 11 can be improved. And when water flows into the terminal 11 from the first groove 111 of the terminal 11, the water can be quickly discharged from the terminal 11 from the second groove 112 of the terminal 11, further improving the water discharge efficiency, further avoiding water from being retained in the terminal 11, and improving the safety of the terminal 11 when in use.

[0042] A junction box comprises a bottom shell 2, a front shell 3 and any one of the above-mentioned terminal assemblies 1. Since the junction box comprises the above-mentioned terminal assembly 1, the beneficial effects of the junction box brought by the terminal assembly 1 can be referred to the above content and will not be repeated here.

[0043] In some embodiments, the terminal 11 and the bottom shell 2 are integrally formed. Specifically, the terminal 11 and the bottom shell 2 are integrally injection molded, so that there is no gap between the terminal 11 and the bottom shell 2, and water is not easy to flow into the junction box from between the terminal 11 and the bottom shell 2, 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.

[0044] In some embodiments, the bottom shell 2 includes a circuit board 21, and the protrusion of the terminal 11 protruding toward the front shell 3 is welded and connected to the circuit board 21. Specifically, the circuit board 21 refers to the power supply PCBA, and PCBA refers to the Printed Circuit Board Assembly 21. The terminal 11 is provided with a protrusion protruding toward the front shell 3, and the protrusion is connected to the circuit board 21, so as to realize the electrical connection between the cable 4, the terminal 11 and the circuit board 21, so that the socket of the junction box has electricity, and the welding of the protrusion and the circuit board 21 can also improve the stability of the connection between the two.

[0045] In some embodiments, the cable 4 is arranged in the first groove 111, and the first groove 111 is opened on the side of the terminal 11 away from the housing 3. Generally, the junction box is arranged in a wall, a groove for installing the junction box is opened on the wall, and the cable 4 is reserved in the wall, and the cable 4 is located on the side away from the junction box housing 3. The first groove 111 is opened on the side of the terminal 11 away from the housing 3, and the cable 4 is arranged in the first groove 111, which facilitates the installation of the cable 4, so as to improve the efficiency of installing the cable 4 into the terminal 11 of the junction box.

[0046] In some embodiments, the locking member 12 is disposed in the second groove 112, and the second groove 112 is opened on the side of the terminal 11. Specifically, on the basis that the cable 4 is disposed in the first groove 111, and the first groove 111 is opened on the side of the terminal 11 away from the face shell 3, the locking member 12 is disposed in the second groove 112, the locking member 12 is a locking screw, an internal thread is arranged on the groove wall of the second groove 112, and the second groove 112 is opened on the side of the terminal 11, so that it is convenient for the locking member 12 to lock the cable 4, so that the cable 4 and the terminal 11 are connected more firmly, and the efficiency of abutting the terminal 11 and the cable 4 together is further improved.

[0047] In addition, the first groove 111 and the second groove 112 can also be arranged in other ways, for example: the locking piece 12 is arranged in the second groove 112, and the second groove 112 is opened on the side of the terminal 11 away from the surface shell 3; the cable 4 is arranged in the first groove 111, and the first groove 111 is opened on the side of the terminal 11.

[0048] In some embodiments, the side wall of the bottom shell 2 is provided with a through hole 22 through which the locking member 12 passes, and the through hole 22 and the second groove 112 are arranged in the same direction. Specifically, the through hole 22 is provided on the side wall of the shell, and the through hole 22 and the second groove 112 are arranged in the same direction, and the locking member 12 passes through the through hole 22 and the second groove 112 at the same time to lock the cable 4. In this way, when water flows into the terminal 11 from the first groove 111, the water flows through the second groove 112 and the through hole 22 in sequence to the outside of the junction box, thereby discharging the water to the outside of the junction box to improve the safety of the junction box when in use.

[0049] Furthermore, an internal thread adapted to the wire locking screw is provided on the inner wall of the through hole 22 , thereby increasing the connection length of the wire locking screw and further improving the fastening effect of the cable 4 and the terminal 11 .
