Abstract

DC60 Canopy (62), for covering the top surface of the connector (52), extends from the reflector (51) and the notch (73), oriented in the direction of the CL axis of the connector (52), opens in the top of the socket (52) to allow air flow into/out of the reflector (51) through the notch (73), which allows contact between the enclosing space in the reflector. (51) with outside air while serving to prevent the infiltration of water into the notch (73) by the use of the roof (62). It is possible to increase the degree of freedom to adjust the shape and size of the notch. This is because the roof and notch are provided in the edge space on the rear surface of the reflector. The arrangement of the roof and the notch does not limit the placement of other components. The circular arc roof or wall (62) for covering the top surface of the slot (52) extends from the body. The reflector (51) and notch (73) which align in the direction of the CL axis of the connector (52) are opened in the top of the connector (52) to allow air flow into/. It exits the reflector (51) through a notch (73), which makes contact between the enclosed space in the reflector (51) and the outside air. while serving to prevent water infiltration into the notch (73) by using a circular arc-shaped roof or wall (62). notch in the slot Thus it is possible to increase the degree of freedom to adjust the shape and size of the notch. This is because the roof and notch are provided in the edge space on the rear surface of the reflector. The roof and notch arrangement does not limit the placement of other components.

Claims (3)
