Description

A kind of radiator with electric source wire securing device

Technical field

The utility model is related to the radiator in LED field, more particularly to LED.

Background technology

Application of the LED product in illumination is more and more concerned, because its high energy efficiency, long-life and environmental protection etc. are excellent Gesture, is considered as most potential forth generation lighting source, so that LED is used widely in lighting field.LED/light source makes Radiating during is a very the key link.

The patent of Application No. 201220050777.5 discloses a kind of radiator of LED bay light, including hollow shaft, institute State and fin be provided with the outer surface of hollow shaft, the front end of the fin is Y shape, and the Y shape opening outwardly, the reality The front end of fin is set to Y wooden fork shapes with new provided radiator, fin and extraneous contact area is being added While cause front end fin comparatively dense, and the position of the two Y wooden fork shapes in front end is that internal heat is handed over extraneous between fin The position changed, the intensive layout of fin causes heat exchange to be affected.

In addition, radiator is generally arranged at lamp body afterbody, light fixture in use, the temperature of radiator can be unusual high, and lamp The power line of tool is directly passed often by the hole on radiator and fixed on a heat sink, due to the not anti-drawknot of power line Structure, when power line is by downward pulling force, power line, which is easy to come off from light fixture, causes light fixture to damage, and prolonged high Temperature also can be unfavorable to power line.

Utility model content

The purpose of this utility model is to provide a kind of good heat dissipation effect, can prevent power line from dropping from damaging and be avoided that electricity The source line length time contacts the radiator of high temperature fin.

The utility model is achieved through the following technical solutions above-mentioned purpose：

It is provided with a kind of radiator with electric source wire securing device, including hollow shaft, the outer surface of the hollow shaft Fin, it is characterised in that the intracavitary of the hollow shaft is provided with electric source wire securing device, the electric source wire securing device is position The annulus being be arranged in parallel in hollow axocoel center and its upper surface, the annulus is consolidated by the support being fixed on inner wall of hollow shaft It is scheduled on hollow shaft intracavitary.

Preferably, the annulus is made up of orthodrome and small arc-shaped, and the orthodrome is solid by first support, second support Hollow shaft intracavitary is scheduled on, the small arc-shaped is fixed on hollow shaft intracavitary by the 3rd support, and the 3rd support is hinged on by rotating shaft On inner wall of hollow shaft, the orthodrome be provided at both ends with to small arc-shaped direction extend prevent small arc-shaped continue up it is convex Block, the small arc-shaped is provided at both ends with the depression mutually agreed with projection.

Preferably, the front end of the fin be Y shape, and the Y shape opening outwardly.

Specifically, open up fluted in a branch in the Y shape front end branch.

Specifically, the thickness of the fin is 1-2mm.

Preferably, it is enclosed with heat-insulating material on the annulus.

The utility model by setting electric source wire securing device on a heat sink so that power line passes through radiator hollow shaft In annulus pass, it is to avoid the power line fin higher with temperature is directly contacted；By in the Y shape front end two of fin Groove is set in a branch in individual branch, while fin is increased with extraneous contact area so that fin Front end layout is unlikely too close, and the heat between influence fin outwardly circulates.

Embodiment

The utility model is described in detail below in conjunction with the accompanying drawings：

As shown in Figure 1 and Figure 2, a kind of radiator with electric source wire securing device, including hollow shaft 1, the hollow shaft 1 Outer surface on be provided with fin 2, the intracavitary of the hollow shaft 1 is provided with electric source wire securing device 3, and the power line is fixed Device 3 is the annulus being be arranged in parallel positioned at hollow axocoel center and its upper surface, and the annulus is by being fixed on inner wall of hollow shaft On first support 311, second support 312, the 3rd support 321 be fixed on hollow shaft intracavitary, by the electric source wire securing device only An annulus for being located at hollow shaft intracavitary is only designed as, the influence that the device radiates to LED can be effectively reduced；Set Put at hollow axocoel center and parallel with the upper surface of cavity, power line when being stretched out by the annulus, can avoid completely with Fin is contacted；Meanwhile, electric source wire securing device is designed as circular ring structure, in use, it is straight that an one end is arranged on electric wire Footpath one end diameter bigger than annulus is less than the silica gel plug of annulus, and wherein diameter is stuck in annulus less than one end of annulus, can be effective Being come off when avoiding power line by external tensile force causes light fixture to damage.

Silica gel plug is put for convenience and is positioned over after power line in the cavity of hollow shaft 1 and power line is checked, Be the structure that is made up of orthodrome 31 and small arc-shaped 32 by toroidal design, the orthodrome 31 by first support 311, second Frame 312 is fixed on hollow shaft intracavitary, and the first support 311, second support 312 are weldingly fixed on hollow shaft cavity wall, institute State small arc-shaped 32 and hollow shaft intracavitary is fixed on by the 3rd support 321, the 3rd support 321 passes through rotating shaft（It is not drawn into figure） It is hinged on inner wall of hollow shaft and can only rotates down upwards, being provided at both ends with to the direction of small arc-shaped 32 for the orthodrome 31 is prolonged The projection 313 for preventing small arc-shaped from continuing up is stretched, the small arc-shaped 32 is provided at both ends with the depression mutually agreed with projection 313 322, when needing power line taking out inspection, the 3rd support 321 is pressed down on, the 3rd support 321 is moved downward, orthodrome Separate, the power line for being arranged with silica gel plug can be now taken out with small arc-shaped, after putting it into, then the 3rd support 321 is upward Pull, now big small arc-shaped is one complete annulus of composition, and the small one end of silica gel plug diameter is set in annulus to be hindered by annulus Gear, now also will not fall off by extraneous pulling force even if power line and causes light fixture to damage.

For the good radiating effect reached, the front end of the fin 2 is Y shape, the opening of the Y shape outwardly, institute State and open up the thickness of fluted 23 and fin 2 in Y shape front end the first branch 21 and the second branch 22 in one of branch and be 1-2mm, preferably 1.5mm, branch and the branch not with groove of the band fluted 23 are alternately arranged successively.

Heat-insulating material such as glass fibre, vacuum offset plate etc. are enclosed with the annulus and further avoids power line by high temperature Influence.

Upper and lower described in the utility model is upper, correspondence to the direction referred to along hollow direction of principal axis towards annulus Another direction be under, the lower end of radiator is connected with light fixture when using, and top is provided with one end of annulus towards outside empty Between.
