Description

Technical Field

[0001] This utility model relates to the field of junction box technology, specifically to a junction box. Background Technology

[0002] A junction box is an electrical device primarily used for connecting and centrally managing cables, wires, and other electrical equipment in a circuit. It consists of a housing, insulator, terminals, and wiring bridges, providing reliable electrical connections and protection. Junction boxes are an indispensable part of electrical equipment and are widely used in power distribution, control, communication, and industrial control fields. However, junction boxes do not facilitate the quick connection of multiple wires during wiring. Therefore, we have proposed an improvement to address this issue. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a junction box that solves the problem mentioned in the background art of making it difficult to quickly connect multiple wires during wiring.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a junction box, comprising a junction box, an inlet pipe at the bottom of the junction box, and an outlet pipe on the side wall of the junction box, wherein the inlet pipe and the outlet pipe are respectively used to insert wires, and further comprising:

[0005] A heat dissipation structure is embedded inside the junction box to dissipate heat from the electrical components inside the junction box;

[0006] The positive terminal is fixedly installed on the top of the heat dissipation structure;

[0007] The negative terminal is fixedly installed on the top of the heat dissipation structure and located on top of the positive terminal.

[0008] The power connection assembly is fixedly installed at the bottom of the heat dissipation structure and is electrically connected to the positive power connection terminal and the negative power connection terminal respectively.

[0009] An end cap, threadedly connected to the top of the junction box, is used to close the junction box.

[0010] Optionally, the heat dissipation structure includes a central hollow cylindrical tube and heat dissipation fins fixedly connected to the side wall of the hollow cylindrical tube. The heat dissipation fins are arranged in a ring array on the side wall of the hollow cylindrical tube. The heat dissipation fins can dissipate heat from the positive and negative terminals, ensuring that the positive and negative terminals work effectively.

[0011] Optionally, both the positive and negative terminals have four conductive tabs, each with a snap-fit ​​hole. A fixing buckle is snapped into the snap-fit ​​hole to quickly fix the wire.

[0012] Optionally, the positive terminal has a through hole in the middle, and the negative terminal is inserted through and fitted with a gap in the middle of the positive terminal. The negative terminal is inserted into the positive terminal and extends to the bottom of the heat dissipation structure. The negative terminal and the positive terminal will not affect each other.

[0013] Optionally, the fixing buckle includes a buckle head, the side wall of which has two buckle teeth. The two buckle teeth are fitted with a gap. The two buckle teeth are made of soft plastic and expand outward with a diameter larger than the snap-fit ​​hole when the squeezing force is lost. Squeezing the two buckle teeth will insert the fixing buckle into the snap-fit ​​hole. After snapping, the two buckle teeth expand with each other to prevent the fixing buckle from detaching from the conductive plate.

[0014] Optionally, the sidewall of the clip head also has a spring plate. The clip head and the clip teeth are made of insulating material. The spring plate can provide a squeezing force, thereby abutting the wire and making the wire further abut the conductive plate to supply power.

[0015] Optionally, the power connection assembly includes a power connection base fixedly connected to the bottom of the heat dissipation structure. The power connection base is provided with conductive springs that abut against the positive power connection terminal and the negative power connection terminal, respectively. The power connection base is electrically connected to the wire by bolts, and the power connection base can be connected to the positive and negative terminals that supply current, respectively.

[0016] Optionally, the side wall of the junction box is provided with a threaded groove, the end cover is threadedly connected to the junction box, and a sealing ring is snapped between the end cover and the junction box. The threaded connection between the end cover and the junction box and the snapping of the sealing ring ensure the airtightness of the entire junction box.

[0017] This utility model provides a junction box with the following advantages:

[0018] This junction box, with its junction box, heat dissipation structure, positive and negative terminals, connection components, and end caps, allows wires to pass through and connect to the positive and negative terminals. During assembly, simply place the connecting wires on the connecting plates and insert the locking clips into the locking holes for quick and easy connection. After locking, the spring plates abut against the wires, ensuring effective fixation and achieving rapid connection. It also allows for easy arrangement of wires in different directions, preventing interference. Furthermore, the heat dissipation structure effectively cools the positive and negative terminals, enhancing safety. Attached Figure Description

[0032] End cap 60, threaded connection to the top of junction box 10 for sealing junction box 10.

[0033] As a preferred embodiment, based on the above method, the heat dissipation structure 20 further includes a central hollow cylindrical tube 21 and heat dissipation fins 22 fixedly connected to the side wall of the hollow cylindrical tube 21. The heat dissipation fins 22 are arranged in a ring array on the side wall of the hollow cylindrical tube 21. The heat dissipation fins 22 can dissipate heat from the positive terminal 30 and the negative terminal 40, ensuring that the positive terminal 30 and the negative terminal 40 work effectively.

[0034] Both the positive terminal 30 and the negative terminal 40 have four conductive plates. Each conductive plate has a snap-fit ​​hole 31, and a fixing buckle 32 is snapped into the snap-fit ​​hole 31. The fixing buckle 32 can be quickly snapped into the snap-fit ​​hole 31 to quickly fix the wire.

[0035] The positive terminal 30 has a through hole in the middle. The negative terminal 40 is inserted through the middle of the positive terminal 30 and is gap-fitted with the negative terminal 40. The negative terminal 40 is inserted into the positive terminal 30 and extends to the bottom of the heat dissipation structure 20. The negative terminal 40 and the positive terminal 30 will not affect each other.

[0036] As a preferred embodiment, based on the above method, the fixing buckle 32 further includes a buckle head 321, the side wall of the buckle head 321 has two buckle teeth 322, the two buckle teeth 322 are fitted with a gap, the two buckle teeth 322 are made of soft plastic material, and when the squeezing force is lost, the diameter of the outward expansion is larger than that of the snap-fit ​​hole 31. Squeezing the two buckle teeth 322 can insert the fixing buckle 32 into the snap-fit ​​hole 31.
