[0002] The lamp anti-pulling power line tail clamp structure is a device installed on a lamp, used for fixing and protecting the connection part of the power line and the lamp, for preventing the power line from loosening or being damaged due to external force. With the continuous improvement of electrical safety standards, the lamp industry also faces more stringent requirements. Various safety certification agencies, such as UL and CE, have clear regulations on the safety of the power line connection of the lamp. These regulations require lamp manufacturers to take effective measures to prevent the power line from loosening or being damaged under normal use and reasonable external force.

[0003] According to the lamp safety requirements, the lamp needs to set up an anti-pulling device and pass the pull test. Currently, there are various types of wire tail clamps on the market, which mostly achieve the anti-pulling function by pulling the wire out of the lamp. However, in actual operation, sometimes the wire needs to be inserted from the outside of the lamp. At this time, the current tail clamp structure cannot achieve the locking and anti-pulling function.

[0004] Therefore, in view of the above problem that most wire tail clamps on the market are designed to pull the wire out of the lamp to prevent pulling, but in actual operation, the wire sometimes needs to be inserted from the outside of the lamp, and the existing tail clamp structure cannot achieve the locking and anti-pulling function, a lamp anti-pulling power line tail clamp structure can be designed, which is composed of multiple steps, and the cross section of the step is longer than the width. The first step matches the center wire hole of the LED lamp panel to avoid rotation, the second step realizes the locking and anti-pulling device, the third step structure realizes the 360 rotation function, and the fourth step realizes the function of preventing the wire from being pushed in reverse and covering the wire hole.

[0023] Please refer to Figures 1-4In the embodiment, the tail cable 1 is installed through the bottom end of the lamp body shell 3, a cable mounting hole is provided at the center of the lamp body shell 3 for mounting the tail cable 1, and the cable mounting hole is provided at the center of the lamp body shell 3 for mounting the tail cable 1, so that the tail cable 1 has a clear and fixed path when it passes out of the lamp body shell 3. This precise positioning method ensures that the tail cable 1 can pass out from the predetermined position every time, avoiding the interference problem between the ground and other components caused by the unstable wire outlet position. The first step 101 and the second step 102 are the same size as the cable mounting hole, and the third step 103 is installed at the top of the second step 102 for rotating the second step 102, and the size of the third step 103 is smaller than the size of the cable mounting hole. The same size of the first step 101, the second step 102 and the cable mounting hole facilitates the assembly process of the lamp, and when installing the tail cable 1, the worker can accurately install the tail cable 1 to the right position according to the size of the cable mounting hole.

[0025] Please refer to Figures 1-2In the embodiment, the EVA cotton 4 is symmetrically arranged between the lamp body shell 3 and the LED lamp plate 5. The square groove for installing the EVA cotton 4 is arranged in the installation groove of the lamp body shell 3. The EVA cotton 4 has good elasticity and flexibility, and can disperse and absorb the external force, thereby reducing the direct impact on the LED lamp plate 5, reducing the risk of damage to the LED lamp plate 5, and greatly enhancing the overall structural strength of the lamp.

[0026] When working, the worker puts the EVA cotton 4 into the square groove of the lamp body shell 3 located in the installation groove, and ensures that the EVA cotton 4 is symmetrically arranged between the lamp body shell 3 and the LED lamp plate 5, thereby playing a role in buffering and filling the gap. The tail clamp end of the tail clamp wire 1 penetrates into the LED lamp plate 5 from the rectangular hole of the lamp body shell 3. After the tail clamp second step 102 passes through the cable installation hole, the second step 102 needs to be rotated by 90 degrees. The tail clamp first step 101 positions the LED lamp plate 5.

In this way, the tail clamp is also locked and cannot be rotated, thereby realizing the anti-pulling function.

[0027] Through the above steps, the first step 101 installed on the tail clamp wire 1 is positioned on the LED lamp plate 5, thereby providing a stable support point for the tail clamp wire 1. When subjected to a pulling force, the first step 101 can prevent the tail clamp wire 1 from slipping off the LED lamp plate 5. At the same time, the second step 102 installed at the top of the first step 101 can realize the anti-pulling function by rotating. When the tail clamp wire 1 is subjected to an external pulling force, the rotation of the second step 102 blocks the lamp body shell 3, thereby effectively preventing the tail clamp wire 1 from being excessively stretched, protecting the connection between the tail clamp wire 1 and the LED lamp plate 5, ensuring the stability of the lamp outlet under the action of the pulling force, and meeting the lamp safety requirements. In the structure, there is the EVA cotton 4, which can buffer and protect the tail clamp wire 1. When the lamp is subjected to vibration or slight impact, the EVA cotton 4 can absorb the external force and reduce the impact force transmitted to the tail clamp wire 1, thereby preventing the tail clamp wire 1 from being damaged by external mechanical force. The lamp body shell 3 and the LED lamp plate 5 are coaxially arranged, which makes the internal structure of the lamp more regular. The tail clamp wire 1 is arranged between the lamp body shell 3 and the LED lamp plate 5, thereby reasonably utilizing the space between the two, avoiding the disorderly distribution of the tail clamp wire 1 in the lamp, and reducing the problems caused by the entanglement of the wire or the interference with other components.
