Abstract
The utility model discloses a waterproof connection structure, which is used for engagement between an end of a light tube in a lamp and a socket slot. At least a circular groove (102) is arranged on an outer peripheral surface (101) of the end, 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), an inner peripheral surface (201) of the socket slot has a taper, and the end is in compressing seal with the socket slot via the sealing ring (3) and the taper of the inner peripheral surface (201), thereby realizing water proofing by aid of tapered sealing engagement between the sealing ring (3) and the inner peripheral surface (201). The waterproof connection structure can be applied to the lamp field widely.
Description
Technical field
The utility model relates to the waterproof connecting structure of fluorescent tube in a kind of light fixture.
Background technology
Along with the development of the maturation of LED technology, the LED street lamp has replaced traditional street lamp gradually, and the LED street lamp is compared traditional street lamp not only long, advantage such as colourity is good of life-span, the more important thing is the remarkable result aspect energy-conservation.General street lamp is to adopt a large lampshade that light source is encapsulated in to come waterproof in the internal cavity, but seems that like this volume is bigger, and structure is not compact; Existing advanced LED street lamp is to adopt some LED unit fluorescent tube to be installed in the socket of street lamp lamp bracket, but all be simple the installation, structurally do not take any waterproof measure, rainwater is easy to enter socket initiation short trouble etc. from the slit is installed, thereby damages light fixture.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the waterproof connecting structure that matches between a kind of termination that is used for the light fixture fluorescent tube and the outlet slots is provided.
The technical scheme that the utility model adopted is: cooperating between the termination that the utility model is mainly used in fluorescent tube in the light fixture and the slot of socket, on the outer peripheral face of described termination, offer at least one annular groove, socket sealing ring in the described annular groove, the thickness of described sealing ring is greater than the degree of depth of described annular groove, the inner peripheral surface of described slot has a tapering, and the tapering formation by described sealing ring and described inner peripheral surface between described termination and the described slot compresses sealing.
Described outer peripheral face also has a tapering and suitable with described inner peripheral surface.
Also have on the anchor ring of described sealing ring and the suitable tapering of described inner peripheral surface.
Preferably, offer bipassage ring connected in star and difference socket sealing ring on the described outer peripheral face, sealed waterproof effect is better.
The side end face of described termination is provided with jack, is extended with contact flat spring in the described jack, is extended with plug in described slot, and described contact flat spring contacts with plug and turning circuit.
The beneficial effects of the utility model are: owing to offer at least one annular groove on the outer peripheral face of described termination, socket sealing ring in the described annular groove, the thickness of described sealing ring is greater than the degree of depth of described annular groove, the inner peripheral surface of described slot has a tapering, tapering formation by described sealing ring and described inner peripheral surface between described termination and the described slot compresses sealing, when the fluorescent tube ecto-entad inserts the slot of described socket, sealing ring can contact and push with the inner peripheral surface of described slot, and contact tight more in past more, play the effect of high performance water proof; Because described outer peripheral face also has a tapering and suitable with described inner peripheral surface, also have on the anchor ring of described sealing ring and the suitable tapering of described inner peripheral surface, described like this outer peripheral face can be close to the parallel inner peripheral surface that closely is adjacent to slot, and the waterproof sealing effect further improves.

The specific embodiment
As Fig. 1, present embodiment is applied to waterproof connecting structure in the LED street lamp.Described LED street lamp comprises socket 2, lamp bracket 4 and the upper shell 3 of some fluorescent tubes 1, fluorescent tube, upper shell 3 is fixedly installed on the top of lamp bracket 4, the front end of lamp bracket 4 is equipped with the power supply 5 of pipeline 6 and street lamp, described socket 2 be fixed on the framework of lamp bracket 4 and with described power supply 5 adaptive electrical connections, described socket 2 is provided with the slot that a row pegs graft for fluorescent tube 1, one end of described fluorescent tube 1 inserts in the described slot of described socket 2, and the other end is connected on the holder 7 of fluorescent tube.
As Fig. 2～shown in Figure 5, have on the termination of jack at described fluorescent tube 1, offer bipassage ring connected in star 102 on its outer peripheral face 101, socket sealing ring 3 in the described annular groove 102, the thickness of described sealing ring 3 is greater than the degree of depth of described annular groove 102, and the side end face of described termination is provided with jack 103, is extended with contact flat spring 104 in the described jack 103, be extended with plug 202 in the described slot of described socket 2, described contact flat spring 104 contacts with plug 202 and turning circuit.The inner peripheral surface 201 of the described slot of described lamp tube socket 2 has a tapering, the radial dimension ecto-entad of described slot diminishes gradually, in the time of in described slot is inserted in described termination, sealing ring 3 is close to described inner peripheral surface 201 owing to being squeezed, and reaches the purpose of water-tight.Simultaneously, described outer peripheral face 101 also has a tapering and suitable with the inner peripheral surface 201 of described slot, also have the tapering suitable on the anchor ring of described sealing ring 3 with described inner peripheral surface 201, can make the outer peripheral face 101 omnibearing inner peripheral surfaces 201 that are adjacent to slot like this, further improve the waterproof sealing effect.
Structure of the present utility model is not limited in the LED street lamp among the above embodiment, and the waterproof connecting structure similar of the present utility model that relates in any light fixture is all within protection category of the present utility model.
The utility model can be widely used in field of light fittings.
