Description

Technical Field

[0001] This application relates to the field of street lighting technology, and in particular to a quick-plug lamp head connection assembly for street lights. Background Technology

[0002] Streetlights are luminaires that provide illumination to roads, broadly referring to all luminaires within the road surface lighting range used in daily lighting. Streetlights are widely used in various locations requiring illumination. A streetlight typically consists of three parts: the pole, the boom, and the luminaire (or lamp head). The primary function of the luminaire is illumination, its most basic function, ensuring the safe travel of pedestrians and vehicles at night. However, as streetlights operate for extended periods in various environments, they experience a certain failure rate, and the various electrical components installed within them are consumables requiring maintenance and replacement.

[0003] Because existing streetlights are installed at high altitudes, the installation and fixing of the lights and the cantilever arms are complicated. Maintenance personnel need to work at heights for long periods of time during the installation and dismantling of the lights, which poses certain safety hazards to their personal safety. At the same time, the way the lights are connected and fixed to the poles makes dismantling difficult for maintenance personnel, greatly increasing their maintenance efficiency and labor intensity, and resulting in higher safety risks. Utility Model Content

[0004] Purpose of this utility model: This application aims to overcome the defects of the prior art and propose a quick-plug lamp head connection assembly for streetlights.

[0005] Technical Solution: A quick-connect and disconnectable lamp head connection assembly for streetlights includes a connection unit for connecting lamp heads and a plug-in unit for connecting lamp arms. The connection unit includes a connection housing and a snap-fit ​​device disposed on the connection housing. The plug-in unit includes a sleeve and a plug tube fixed to the sleeve. The plug tube can be inserted into the connection housing. The plug tube has a platform portion with a groove that mates with the snap-fit ​​device. The connection housing has a guide recess that matches the platform portion, and the snap-fit ​​device is disposed on the guide recess. A plug terminal is installed inside the connection housing, and a socket terminal that mates with the plug terminal is installed inside the plug tube.

[0006] Preferably, the connection between the sleeve and the insertion tube is provided with a flange for limiting the connection housing, a limiting plate is provided inside the sleeve, and a first threading hole for threading is provided at the limiting plate.

[0007] The flange can limit the insertion position of the connecting housing and the plug tube, while the limiting plate can limit the position of the lamp arm inserted into the sleeve. The first wire hole is used for the power cord connection.

[0008] Preferably, the inner wall of the connecting housing is provided with two plug mounting posts for installing plug terminals; the inner wall of the plug tube is provided with two socket mounting posts for installing socket terminals.

[0009] The two plug mounting posts and the two socket mounting posts are positioned one-to-one to ensure stable mating of the plug terminals and socket terminals.

[0010] Preferably, the end of the connecting housing away from the plug tube has an arc-shaped protrusion plate, and the arc-shaped protrusion plate has a mounting slot for mounting the lamp holder; the arc-shaped protrusion plate also has a second wire hole.

[0011] By using the corresponding bolts to connect to the threaded hole at the rear of the lamp holder through the mounting slot, the lamp holder can be connected and fixed; the second wire hole is used for the cable to be inserted into the lamp holder.

[0012] Preferably, the arc-shaped protruding plate is provided with a toothed groove, which can cooperate with the toothed groove at the lamp head to complete the angle adjustment.

[0013] The arc-shaped protrusion plate has an arc structure that can completely overlap with the arc surface of the cable outlet at the rear of the lamp head. The angle can be adjusted by using the toothed grooves on the arc surface of the arc-shaped protrusion plate to cooperate with the corresponding toothed grooves at the rear of the lamp head.

[0014] Preferably, the sleeve is provided with multiple mounting threaded holes, and the mounting threaded holes are threadedly connected with clamping bolts for clamping the lamp arm.

[0015] After the bolt passes through the mounting threaded hole, it presses against the lamp arm, thereby fixing the sleeve on the lamp arm.

[0016] Preferably, the insertion tube has a flow guide groove near the flange, and the flange has a flow guide port at the bottom of the side near the insertion tube, and the flow guide port is connected to the flow guide groove.

[0017] The purpose of the flow channel is to prevent water from accumulating. When water flows in from the surface of the connector along the installation gap between the connector and the connecting shell, the water can be collected through the flow channel and discharged from the flow port.

[0018] Preferably, the guide recess includes two side plates, a back plate, and a bottom plate. The two side plates and the back plate are all connected to the bottom plate. The two side plates are connected to each other through the back plate. The back plate is located on the side away from the insertion tube. The bottom plate has a through hole that allows the fastening element of the buckling device to pass through.

[0019] First, install the lamp holder at the connecting unit. Then, press the bar button downwards. When the fastener at the front of the bar button is in the lifted state, fit the connecting housing onto the plug-in connector. Utilize the guiding function of the guide recess to correctly fit and fix the connecting unit and the plug-in unit. After fitting the connecting unit into place, release the bar button. The fastener on the bar button will automatically fall into place under the action of the spring and engage with the corresponding slot on the plug-in unit through the through hole on the connecting unit, automatically locking the engagement part. At this point, the connecting unit and the plug-in unit are fixed, and the lamp holder will not automatically fall off when you try to pull it out by hand.

[0020] During disassembly, first press the bar button downwards until the fastener at the front of the bar button is in the lifted position, then pull out the connecting unit. At this point, the socket terminal on the plug unit will disconnect from the plug terminal inside the connecting unit, thus completing the disassembly of the lamp holder.

[0021] Preferably, the buckling device includes a bar-shaped button, a torsion spring disposed inside the bar-shaped button, and two positioning bolts for mounting the bar-shaped button on the guide recess. The guide recess has positioning threaded holes on its two side plates, and the bar-shaped button has positioning through holes concentric with the positioning threaded holes on its two side plates. The positioning bolts pass through the positioning threaded holes and the positioning through holes in sequence, and the torsion spring is sleeved on the outside of the shank of the positioning bolt.

[0022] The fastener and the bar button are integrally molded and equipped with a torsion spring, so that the fastening device has a self-locking function to prevent the parts from coming off due to vibration after the parts are fastened.

[0023] Beneficial effects:

[0024] 1. The present application is characterized by its simple structure and convenient installation. The installation of the lamps can be quickly completed by plugging and unplugging the connecting components, which greatly facilitates the installation and disassembly of the workers, improves the work efficiency of the workers and reduces the time spent in high-altitude operations, improves the personal safety of high-altitude workers, and can quickly repair or reduce long-term power outages caused by lamp failures.
