Detailed Implementation

[0018] To facilitate understanding of this utility model, a more complete description is provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0019] See appendix Figure 1-6 As shown, in this embodiment, a junction box includes three main parts: a body 1, a wiring cover 2, and an inlet cover 3. Specifically, Body 1: As the basic structure of the junction box, it provides support and fixation.

[0020] Wiring cover 2: Its tail end is pivotally mounted to the body 1, while its front end is snapped into the body 1, forming a flip-open / closed structure. When the wiring cover 2 is flipped and closed relative to the body 1, the two together form a wiring cavity. The closing position between the front end face of the wiring cover 2 and the front end face of the body 1 is designed with a wiring through hole 21 that communicates with the wiring cavity, for passing through and introducing one or two external cables so that one or two cables can pass through the wiring through hole 21 into the wiring cavity.

[0021] Cable inlet cover 3: It is fastened to the main body 1 and secured by pre-set screws, forming a cable inlet cavity when closed with the main body 1. The closing position between the tail end face of the cable inlet cover 3 and the tail end face of the main body 1 is also designed with a cable inlet hole 31 that communicates with the cable inlet cavity, for passing through and introducing an external cable.

[0022] In this embodiment, the wiring cavity is connected to the inlet cavity, and a terminal 4 fixed on the body 1 is provided at the junction of the wiring cavity and the inlet cavity. Specifically, the terminal 4 in this embodiment is a double-ended three-terminal terminal 4. The cable introduced from the wiring hole 21 is connected to the three-terminal terminal 4 at one end, and the cable introduced from the inlet hole 31 is connected to the three-terminal terminal 4 at the other end, thus realizing the electrical connection of the cable.

[0023] In this embodiment, the inner wall of the connector cover 2 has at least one first wire-passing clamping tooth 22 formed near the connector hole 21, and the body 1 has at least one second wire-passing clamping tooth 11 formed at the corresponding position. The two are arranged opposite to each other to form a clamping effect on the cable introduced into the connector hole 21. Similarly, the inner wall of the cable inlet cover 3 and the body 1 also have at least one third wire-passing clamping tooth 32 and at least one fourth wire-passing clamping tooth 12 formed near the cable inlet hole 31, respectively, which also form a clamping effect on the cable introduced into the cable inlet hole 31, effectively preventing the cable from being pulled. Further, preferably, in this embodiment, there are two first wire-passing clamping teeth 22, one second wire-passing clamping tooth 11, one third wire-passing clamping tooth 32, and one fourth wire-passing clamping tooth 12.

[0024] In this embodiment, considering that in actual use, the cable introduced from the inlet hole 31 may be a three-core round wire or a two-core flat wire, the difference between the three-core round wire and the two-core flat wire is that the cable thickness is different. The two-core flat wire is thinner, and it is impossible to clamp the two-core flat wire by relying on the third wire guide tooth 32 and the fourth wire guide tooth 12. Therefore, as an optional solution, the third wire guide tooth 32 on the inlet cover 3 is detachably fastened with a movable wire guide buckle 5. The top surface of the movable wire guide buckle 5 is formed with a fifth wire guide tooth, which is arranged opposite to and offset from the fourth wire guide tooth 12 and the gap between the fifth wire guide tooth and the fourth wire guide tooth 12 is smaller, which can provide additional cable fixing ability and is suitable for clamping the two-core flat wire.

[0025] Furthermore, the bottom surface of the movable wire clamp 5 in this embodiment is formed with a groove for the relative insertion and engagement of the third wire guide tooth 32, thereby realizing that the movable wire clamp 5 can be detachably fastened to the third wire guide tooth 32, greatly increasing flexibility and adaptability.

[0026] In this embodiment, connecting ears 24 are formed on both sides of the tail end of the wiring cover 2, and a horizontal shaft portion 241 is formed on the opposite surface of the connecting ears 24. Shaft holes 14 are formed on both sides of the body 1 for the horizontal shaft portion 241 to be rotated and engaged, realizing the pivot connection of the wiring cover 2 and enabling the wiring cover 2 to be smoothly flipped open and closed. Fastening portions are formed on both sides of the front end of the wiring cover 2, and movable internal teeth 23 are formed on the opposite surface of the fastening portions. Fixed external teeth 13 are formed on both sides of the front end of the body 1 to engage and tighten with the movable internal teeth 23, ensuring the stability of the wiring cover 2 in the closed state. The tight engagement of the movable internal teeth 23 and the fixed external teeth 13 effectively prevents the wiring cover 2 from being accidentally opened.

[0027] In actual use, users can first open the wiring cover 2 and the inlet cover 3, pass the two cables through the wiring hole 21 and the inlet hole 31 respectively, and then connect the two cables to the corresponding terminals 4. Then, close the wiring cover 2 and the inlet cover 3 by snapping and screwing. Finally, use the corresponding wire-passing teeth to tighten the cables to ensure the sealing and safety of the junction box.

[0028] In this embodiment, a groove is provided on the bottom surface of each fastening part, and a clearance groove communicating with the groove is provided on the outer peripheral surface of each fastening part. Thus, when it is necessary to open the wiring cover 2, the operator only needs to insert a screwdriver into the groove and press the screw shaft against the side of the groove away from the movable inner tooth 23. Then, by turning the screwdriver, the fastening part can be forced to deform outward, thereby disengaging the movable inner tooth 23 from the fixed outer tooth 13 to unlock it. Finally, the wiring cover 2 can be flipped open.

[0029] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or alterations made by those skilled in the art to the technical solution of this utility model without departing from its scope are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its scope should be covered within the protection scope of this utility model.
