Description

Technical Field

[0001] The invention relates to the technical field of LED street lamps, and in particular to a power line connection structure for LED street lamps. Background Art

[0002] The field of LED street lamp technology focuses on the technical scope of light-emitting diode (LED) applications in street lamp lighting. It covers LED chip manufacturing, optical design, heat dissipation technology, drive circuit research and development, intelligent control, and lamp structure design, etc. It aims to achieve efficient, energy-saving, environmentally friendly and long-life road lighting solutions. LED street lamps use the LED chip to emit light under the action of forward voltage, and the electrons and holes recombine to generate light. The drive circuit converts AC power into stable DC power to power the LED and achieve dimming. At the same time, the heat generated by the LED is dissipated with the help of the heat dissipation structure to ensure that it works stably and efficiently at the appropriate temperature.

[0003] However, the traditional LED street light power cord connection structure is to strip the insulation layer of the two wires that need to be connected, and then twist their metal cores together. This connection method is relatively complicated during the installation process, and it consumes time and manpower. When the street light needs to be repaired or parts need to be replaced, these complex operations are also required to separate the power cord, which increases the difficulty and time cost of maintenance.

[0015] Working principle: install the wire body 11 inside the lamp pole 2, then pass the wire body 11 through the bundle tube opening 10, and connect one end of the wire body 11 to the plug 12. There are multiple conductive metal sheets inside the plug 12, which are tightly matched with the corresponding metal contact points in the socket. During the insertion process, the metal sheet of the plug will push the spring sheet in the socket. After being inserted into place, the spring sheet returns to its original state and locks the plug tightly, while ensuring that the current can be smoothly transmitted through the metal contact points, so that no additional tools are needed when connecting the power supply. The installer can directly align the plug with the socket and insert it to achieve quick connection, which greatly shortens the installation time of LED street lamps and speeds up the project progress. In large-scale street lamp installation projects, the use of quick plug-in connection can save 30% to 50% of installation time compared with traditional connection methods;

[0016] Install the wire body inside the lamp pole, then pass the wire body through the bundle tube opening, connect one end of the wire body to the plug, and then manually push the handle, the handle will drive the extrusion plate to slide inside the fixed ring, the sliding rod will drive the tooth groove to drive the buckle to the outer wall of the fixed block, when the sliding rod and the tooth groove slide, the spring will drive the fixed block to reset, the sliding rod will drive the extrusion plate to fix the wire body, so that the wire body can maintain the correct position and angle when connected, avoiding the connection point offset due to installation error or external force, thereby ensuring smooth current transmission and maintaining the normal brightness and performance of the street lamp;

[0017] When it is necessary to fix the lower shell one and the upper shell one, the connecting disk is manually rotated, and the connecting disk will drive the connecting rod to rotate. The rotation of the connecting rod will drive the spring two to pull the card tooth, and at the same time will pull the spring three. The spring two will drive the card tooth to slide inside the cross frame, and the lower shell one will be installed on the upper surface of the upper shell one. Then the connecting disk is released, and the spring three and the spring two will rebound, driving the card tooth to be stuck on the inner top wall of the outer shell two. When it is necessary to open the lower shell one and the upper shell one, the connecting disk is manually rotated, and the connecting disk will drive the connecting rod to rotate. The rotation of the connecting rod will drive the spring two to pull the card tooth, and at the same time will pull the spring three. The spring two will drive the card tooth to slide inside the cross frame, and finally the lower shell one and the upper shell one will be opened. Therefore, when it is necessary to inspect the connection part of the wire body, replace parts or troubleshoot, the maintenance personnel can quickly access the internal circuit without spending a lot of time to disassemble complex screws or other fixing devices, thereby reducing maintenance time and labor costs.

[0018] The present invention provides a LED street lamp power line connection structure, which has the following beneficial effects:

[0019] 1. The present invention installs the wire body inside the lamp pole and connects the wire body to the plug, so that no additional tools are needed when connecting the power supply. The installer can directly align the plug and the socket and insert them to achieve quick connection, which greatly shortens the installation time of LED street lights and speeds up the project progress. In large-scale street light installation projects, the use of quick plug-in connection can save 30% to 50% of installation time compared with traditional connection methods.

[0020] 2. The present invention manually pushes the handle, and the handle will slide inside the extrusion plate and the fixed ring. The sliding of the sliding rod will drive the tooth groove to drive the buckle to the outer wall of the fixed block, so that the wire body can maintain the correct position and angle when connected, avoiding the connection point offset due to installation error or external force, thereby ensuring smooth current transmission and maintaining the normal brightness and performance of the street lamp.

[0021] 3. The present invention manually rotates the connecting disk, which drives the connecting rod to rotate. The rotation of the connecting rod drives the second spring to pull the latching teeth, so that when the connection part of the wire body needs to be inspected, parts replaced or faults checked, maintenance personnel can quickly access the internal circuit without spending a lot of time to disassemble complicated screws or other fixing devices, reducing maintenance time and labor costs.
