Connector of the present utility model is formed using high temperature resistant plasticity modified plastics integrated injection molding, is noted using this kind of plastics Modeling connector is not only nontoxic, good weatherability, with preferable stability, and remained in hot environment for a long time Keep good mechanical performance, be difficult frangible, the long service life that becomes fragile.

Further, the inwall of the upper bit is additionally provided with the fixed component for making lampshade be fixedly connected with upper bit.

Further, the fixed component include be symmetrically set in upper bit inwall and positioned at the first draw-in groove both sides boss, Located at boss top and coordinate the screens of boss fastening lampshades and be symmetrically set in upper bit inwall and below the first draw-in groove Second draw-in groove.

Further, the lampshade is provided with the raised line with clamping matching clamping.

Further, the shape of the LED luminescence units and the cross sectional shape of lampshade match and are installed on boss and lamp Between cover.

The effect of boss and the second draw-in groove is support LED luminescence units and lampshade, and screens and the effect of raised line are to coordinate The lampshade that boss is fixed on boss and the second draw-in groove, also secures LED luminescence units while fastening lampshades, in this way, Can make to realize step dismounting between LED luminescence units, lampshade and connector three and a step is installed, installation and removal are convenient And LED will not be damaged.

Further, the inwall of the lower portion is arranged with stopper slot.The stopper slot coordinates with lamp holder and can be used to fix Clamping is installed on the driver in LED.

In sum, the lower end diameter of the utility model upper bit is more than lamp holder external diameter and is communicated with inside connector First through hole；The upper end section of upper bit is more than lampshade section, and is communicated between the upper end inwall and lampshade of upper bit The second through hole inside connector, the utility model solves the problems, such as that the lampshade of existing LED can influence LED to radiate, and The flowing between the air inside connector and outside air is accelerated, LED is radiated in time, be effectively improved The radiating efficiency of LED, extends the service life of LED.Fixed component of the present utility model makes LED luminescence units, lampshade And step dismounting and step installation are realized between connector three, installation and removal are convenient and will not damage LED.
