The invention discloses a safety connecting plug for a direct current charging gun. The safety connecting plug comprises a fixing block and threaded fixing pillars. A fixing connecting pillar is arranged in the middle of the rear end of the fixing block. Second clamping grooves are formed inside the left end and the right end of the fixing connecting pillar. Due to the fact that the safety connecting plug is provided with an internal threaded connector and the threaded fixing pillars, the inner wall in each fixing insertion hole pillar can be expanded, and external insertion pillars cannot befixed through the fixing insertion hole pillars; at the moment, the threaded fixing pillars are rotated, and external threaded bodies on the outer walls of the fixing insertion hole pillars are rotated to be separated from internal threaded fixing connecting holes and fixing internal threaded holes in the internal threaded connector; the internal threaded connector is rotated to be separated fromthe threaded fixing pillars, and thus, new threaded fixing pillars can be replaced; other equipment can continue to work; and in this way, resources are saved, and in addition, property losses are reduced.
Description
technical field [0001] The invention belongs to the related technical field of DC charging guns, and in particular relates to a safety plug connector for DC charging guns. Background technique [0002] The concept of environmental protection is deeply rooted in the hearts of the people. More and more people choose new energy vehicles instead of travel. The growth of this product also promotes the development of the new energy vehicle charging gun industry. [0003] The existing DC charging gun technology has the following problems: when the existing DC charging gun is in use, the telecommunications connection jack in the safety plug connector will expand, so that the telecommunications connection jack cannot fix the external connection plug, so that the safety plug The connector can no longer be used, and the telecommunications connection jack cannot be replaced, which not only wastes resources, but also increases the loss of property. Contents of the invention [0004] T...
