Example Embodiment

[0015] like figure 1 , In this embodiment, the waterproof connection structure is applied to LED street lamps. The LED street lamp comprises several lamp tubes 1, sockets 2 of the lamp tubes, a lamp frame 4 and an upper shell 3, the upper shell 3 is fixedly arranged above the lamp frame 4, and the front end of the lamp frame 4 is equipped with a pipe 6 and a street lamp. A power supply 5, the socket 2 is fixed on the frame of the lamp holder 4 and electrically connected with the power supply 5, the socket 2 is provided with a row of slots for the lamp tube 1 to be plugged in, the lamp tube 1 One end is inserted into the slot of the socket 2, and the other end is clamped on the fixing seat 7 of the lamp tube.

[0016] like Figure 2 to Figure 5 As shown, on the end of the lamp tube 1 with the socket, two annular grooves 102 are opened on the outer peripheral surface 101, and the sealing ring 3 is sleeved in the annular groove 102, and the sealing ring 3 The thickness is grea...

Abstract

The invention discloses a waterproof connection structure matched between an end socket of a lighting tube in a light fitting and a slot of a plug socket. The outer peripheral surface (101) of the end socket is provided with at least one annular groove (102), wherein a sealing ring (3) is sleeved in the annular groove (102); the thickness of the sealing ring (3) is larger than the depth of the annular groove (102); the inner peripheral surface (201) of the slot of the plug socket has a taper; the end socket and the slot of the plug socket form a compacting seal through the sealing ring (3) and the taper of the inner peripheral surface (201); and the sealing ring (3) is matched with the taper of the inner peripheral surface (201) in a sealing mode for preventing water. The waterproof connection structure can be widely used in the field of light fittings.

Description

technical field [0001] The invention relates to a waterproof connection structure of a lamp tube in a lamp. Background technique [0002] With the mature development of LED technology, LED street lights have gradually replaced traditional street lights. Compared with traditional street lights, LED street lights not only have the advantages of long life and good chromaticity, but more importantly, they have a significant effect in energy saving. Generally, street lamps use a large lampshade to encapsulate the light source in the inner cavity to waterproof, but this appears to be large in size and not compact in structure; the existing more advanced LED street lamps use several LED unit lamp tubes to install on the street lamp rack. In the socket, but it is only a simple installation, no waterproof measures are taken in the structure, rainwater can easily enter the socket from the installation gap and cause a short circuit fault, etc., thus damaging the lamp. Contents of the...
