Heat-conducting rubber sheet fixing structure and end socket

The invention discloses a heat-conducting rubber sheet fixing structure, which is used for detachably fixing a conducting rubber sheet on the top of a lower end socket. The heat-conducting rubber sheet fixing structure comprises a locating component and a screw; the lower end socket is correspondingly provided with an accommodating hole and a screw hole; the accommodating hole is formed the top of the lower end socket and extends downwards; the screw hole is formed in side surface of the lower end socket, extends inwards and then is communicated with the accommodating hole; the locating component comprises a fixing part and a hooking part, the fixing part is inserted in the accommodating hole and is provided with a slant facing to the screw hole, one end of the hooking part is fixed at the upper end of the fixing part, the hooking part extends to the heat-conducting rubber sheet, and the other end of the hooking part is bent downwards, is protruded and extends, and then is propped against the heat-conducting rubber sheet; a screw thread is connected with the interior of a screw hole and is propped against the slant. According to the heat-conducting rubber sheet fixing structure, the heat-conducting rubber sheet is in closely contact with the lower end socket, and the heat conductivity is good; the screw is transversely arranged and does not burn an electrode lug, and the heat-conducting rubber sheet is conveniently and quickly replaced. Correspondingly, the invention further discloses an end socket having the heat-conducting rubber sheet.
