The insulating body 1 is injection molded from a polyether sulfene (PES) material. In the field of electrical connectors, the plastics of transparent materials are made of polycarbonate (Polycarbonate, PC). For example, the light-pipe in the RJ45 socket connector is made of PC plastic, but the PC plastic heat distortion temperature is 135. Around °C, if the insulating body 1 is made of PC plastic, it will easily cause the melting deformation of the insulating body 1 in the over-temperature furnace (the temperature of the RJ45 socket connector can be as high as 245 °C when soldering through the high temperature furnace). However, it is not found that a transparent plastic with a high temperature resistance of 245 ° C can be produced. The deformation temperature of PES plastic is about 204 ° C, and because the plastic color of PES plastic injection molding is yellow, PES plastic is used to make transparent insulating body 1 and Not considered by the skilled person in the industry. However, the applicant has obtained a number of tests: although the plastic color of the PES plastic injection molding is somewhat yellowish, it does not affect the light transmission of the patch LEDs 22.
