Technical Field
[0001] This utility model relates to the field of explosion-proof street light technology, specifically to an LED explosion-proof street light that is easy to wire. Background Technology
[0002] LED explosion-proof streetlights are widely used in flammable and explosive hazardous environments such as petroleum, chemical, and mining industries, as well as outdoor road lighting scenarios, due to their energy-saving, long service life, and explosion-proof safety features. Their safety, reliability, and ease of installation are the core concerns of the industry.
[0003] Power connection is a crucial step in the installation and commissioning of LED explosion-proof streetlights. Existing LED explosion-proof streetlight power supply boxes typically only have an inlet hole, requiring operators to directly insert external wires into the power supply box to connect to the internal circuit terminals. Due to the limited space inside the power supply box, wiring is difficult, and in hazardous environments, prolonged operation may increase safety risks.
[0004] Therefore, how to simplify the wiring process of LED explosion-proof streetlights, improve the ease of wiring, and at the same time ensure the explosion-proof performance after wiring has become an urgent problem to be solved in the current structural design of LED explosion-proof streetlights. Utility Model Content
[0005] To address the shortcomings in the prior art, this utility model provides an LED explosion-proof street light that is easy to wire.
[0006] The technical solution adopted by this utility model is: an LED explosion-proof street light that is easy to wire, including a lamp board, a lamp body and a power supply box. A wire inlet hole is provided on one side of the power supply box, and a wiring tube extends protruding from one side of the wire inlet hole. A wiring assembly is provided inside the wiring tube. The wiring assembly includes a plug plate, terminals, and fastening bolts. The plug plate is inserted into a groove inside the wiring tube. The plug plate has a terminal slot for installing the terminals. A wiring notch is provided at the bottom of the terminal slot away from the power supply box. A screw hole for screwing the fastening bolt is provided on the bottom wall of the wiring notch. The terminals are connected to the terminal slot, with a wiring hole at one end and the other end extending below the wiring notch.
[0007] Furthermore, both the wiring terminals and the terminal slots have a "T" shaped cross-sectional conductor.
[0008] Furthermore, the end of the connecting tube is provided with an external threaded sleeve, and a screw cap is screwed onto the external threaded sleeve, and a through hole is provided on the screw cap.
[0009] Furthermore, the junction box and the power supply box are integrally die-cast structures.
[0010] Furthermore, the top of the lamp body is provided with several heat dissipation fins at intervals.
[0011] Furthermore, support plates extend from both sides of the junction box, and several reinforcing plates are provided at intervals between the support plates and the junction box.
[0012] The beneficial effects of this utility model are: 1. Significantly improves wiring convenience and reduces operational difficulty: This patent features a junction box protruding at the power supply box's inlet, integrating a wiring assembly consisting of a plug-in plate, terminals, and fastening bolts within the junction box. This eliminates the traditional method of wiring in LED explosion-proof streetlights, which requires workers to delve into the confined space inside the power supply box. Operators can directly perform wiring work in this open and well-lit space. The notch design facilitates wire insertion and positioning, and the precise fit of the screw holes and fastening bolts allows for quick wire fixation. The entire wiring process eliminates the need for repeated adjustments inside the power supply box, effectively simplifying the wiring process and reducing the skill requirements for operators.
[0013] 2. Enhanced Explosion-Proof Safety Performance and Guaranteed Reliability: Considering the common application of LED explosion-proof streetlights in flammable and explosive environments, this patented terminal block structure forms an independent wiring cavity. This effectively isolates external hazardous media from direct contact with the internal circuitry of the power supply box, preventing sealing failures due to limited operating space during wiring. Simultaneously, the plug-in plate and terminal block groove's insertion and removal mechanism ensure stable assembly of the wiring components, while the secure locking bolts guarantee the stability of the electrical connection, reducing the risk of electrical sparks caused by poor contact and further meeting the safety protection requirements of explosion-proof equipment.
[0014] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0021] This utility model provides an LED explosion-proof street light that is easy to wire.
[0022] In this embodiment, refer to Figure 1-2 The LED explosion-proof street light that is easy to wire includes a lamp board 1, a lamp body 2 and a power supply box 3. A wire inlet hole 4 is provided on one side of the power supply box 3, and a wiring tube 5 extends protruding from one side of the wire inlet hole 4. A wiring assembly is provided inside the wiring tube 5. The wiring assembly includes a plug plate 6, a terminal block 7, and a fastening bolt 8. The plug plate is plugged into and pulled into a groove inside the wiring tube. The plug plate is provided with a terminal through groove 9 for installing the terminal block. A wiring notch 10 is provided at the bottom of the terminal through groove away from the power supply box. A screw hole is provided on the bottom wall of the wiring notch 10 for screwing the fastening bolt. The terminal block is connected to the terminal through groove, with a wiring hole 11 at one end and the other end extending below the wiring notch.
[0023] In the above technical solution, a junction box protrudes from the power supply box inlet hole to form a junction tube, and the wiring assembly is integrated into the junction tube to create an independent wiring space. In the wiring assembly, the plug plate is detachably installed by plugging and unplugging with the junction box slide groove. The terminal slot of the plug plate is used to fix the wiring terminal. The wiring notch away from the power supply box provides an operation opening for external wire access. The screw hole on the bottom wall of the notch cooperates with the fastening bolt to press the wire onto the wiring terminal extending to the bottom of the notch. The wiring hole at the other end of the wiring terminal is used to connect with the internal circuit of the power supply box to form a complete conductive path.
[0024] Abandoning the traditional method of wiring deep inside the power supply box, the junction box provides a spacious operating area, and the positioning function of the wiring notch greatly reduces the difficulty of wiring and improves wiring efficiency. The plug-in plate's plug-and-play design facilitates pre-wiring and subsequent maintenance without disassembling the overall power supply box structure. The tightening bolts ensure a firm connection of the wires, reducing the risk of poor contact. At the same time, the enclosed structure of the junction box effectively prevents the intrusion of hazardous media and ensures explosion-proof performance.
[0025] Specifically, the cross-sectional shape of the wiring terminal and the terminal slot is a "T" shaped conductor.
[0026] In this embodiment, the wiring terminals and terminal slots are designed as "T"-shaped conductor structures to ensure the stability of the connection.
[0027] Specifically, the end of the connector is provided with an external threaded sleeve 12, and a screw cap 13 is screwed onto the external threaded sleeve 12. The screw cap 13 is provided with a through hole 14.
[0028] In this embodiment, an external threaded sleeve is provided at the end of the junction box, and a matching screw cap with a through hole is screwed into the external threaded sleeve. External wires are passed through the through hole of the screw cap into the junction box to complete the wiring. After wiring, tightening the screw cap achieves a sealed closure at the end of the junction box. This effectively prevents dust, moisture, and flammable and explosive media from entering the junction box and power supply box, enhancing the overall explosion-proof and protection level. The detachable screw cap facilitates later circuit maintenance, and the through hole limits the wire position, preventing the wire from being pulled loose by external forces and ensuring connection stability. Specifically, the junction box and the power supply box are integrally die-cast structures.
[0029] In this embodiment, the junction box and power supply box are manufactured using an integrated die-casting process, forming a seamless integral structure that eliminates the assembly gaps and weak points of traditional separate connections.
[0030] Specifically, the top of the lamp body is provided with several heat dissipation fins 15 at intervals.
[0031] In this embodiment, several heat dissipation fins are arranged at intervals above the lamp body. The fins increase the contact area between the lamp body and the air. Through the dual effects of air convection and thermal radiation, the heat generated when the lamp panel is working is dissipated more quickly, forming an efficient heat dissipation channel.
[0032] Specifically, support plates 16 extend from both sides of the junction box, and several reinforcing plates 17 are provided at intervals between the support plates and the junction box.
[0033] Support plates are extended on both sides of the junction box, and several reinforcing plates are added at intervals between the support plates and the junction box. The combination of the support plates and reinforcing plates forms a three-dimensional support frame, which distributes the external force borne by the junction box to the main body of the power supply box and improves the structural rigidity of the connection part.
[0034] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
