[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] Embodiment one:

[0029] Please refer to Figures 1 to 4 The utility model provides an LED support that the pin of the radiating fin does not leak, which comprises a support 1, a plurality of soldering pads 2 arranged in the support 1, and a plurality of pins 3 connected with the soldering pads 2 respectively, the end of the pin 3 extends two convex corners 302, and an inward groove 303 is formed between the two convex corners 302, the end of the convex corner 302 is pulled off to form an end face 301, the end face 301 is attached to the edge of the support 1, and the end face 301 does not exceed the cross section of the support 1.

[0030] The pin 3 with the function of the plastic main body 4 is attached to the edge of the support 1, the pin 3 does not leak, the end face 301 is formed by pulling off the convex corner 302, the pin 3 is partially inward, and the cross section of the convex corner 302 gradually decreases.

[0031] In specific use, the end face 301 of the convex corner 302 is attached to the edge of the support 1 and does not exceed the support 1, the inward groove 303 makes the pin 3 partially inward, the convex corner 302 connects the external components and the pin 3, the pin 3 connects the soldering pad 2, and the soldering pad 2 completes the connection function.

[0032] The bottom end of the support 1 is attached to the plastic main body 4, and the pin 3 is embedded in the plastic main body 4. The pin 3 is wrapped by the plastic main body 4, so that the pin does not leak.
