Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to fig. 1-3, an embodiment of the present utility model is provided: a waterproof cover for an electric connector, comprising an electric connector head 1, a waterproof cover 3 mounted on the electric connector head 1; the waterproof cover 3 comprises an end cover 30, an insertion pipe 32 is arranged on the end cover 30, the waterproof cover is inserted into the electric connector head 1 through the insertion pipe 32, and then the waterproof cover 3 is connected with a positioning hole 2 arranged on the electric connector head 1 through a positioning pin 310 arranged on the end cover 30 so as to realize connection and positioning of the waterproof cover 3 and the electric connector head 1; through the mode, the waterproof cover 3 can be smoothly abutted, and meanwhile, the waterproof cover is convenient for the waterproof cover to keep stable and reliable at the position after connection, so that the falling-off times of the waterproof cover 3 are reduced.

Further, a sealing ring 37 is further provided on the outer surface of the insertion tube 32, and a protrusion 33 is further provided on the outer wall surface of the sealing ring 37; the inside of the insertion tube 32 is movably connected with the plug 35, and the plug 35 is connected with the socket 4 arranged in the electric connector head 1, so that when the insertion tube 32 enters the electric connector head 1, the sealing ring 37 and the protrusions 33 are enabled to be tightly attached between the electric connector head 1 and the insertion tube 32, and in addition, the number of the protrusions 33 is two, so that the insertion tube 32 and the electric connector head 1 have double sealing capability.

Based on the above, the waterproof cover 3 is guided by the cannula 32 to smoothly enter the electric connector head 1 while the waterproof capability and the dustproof capability of the electric connector head 1 are improved, and the waterproof cover 3 and the electric connector head 1 are connected smoothly and simultaneously, the waterproof cover is simple and convenient.

Further, since the outer wall surface of the cannula 32 is further provided with the fixing groove 31 for fixing the sealing ring 37, the sealing ring 37 can be positioned by the fixing groove 31 to prevent the cannula 32 from sliding on the cannula 32 during movement.
