Detailed Description

The utility model will now be described in further detail with reference to the drawings and examples. Wherein like parts are designated by like reference numerals.

Referring to fig. 1 to 4, a new national standard lead-acid plug of the present embodiment includes a housing 1, three pins 2 positioned on the housing 1, and one clip pin 3;

based on the prior art, a plurality of fasteners 4 which are distributed around the end surface outline of the shell 1 and used for outlining the rubber coating are integrally formed at the edge of the end surface of the shell 1 penetrated by the pins 2 and the clamping pins 3, the projections of the fasteners 4 in the end surface outline direction are all L-shaped, one ends of the fasteners 4 are integrally formed with the outer wall of the shell 1, the other ends of the fasteners 4 are arranged in the same direction with the opening of the inner cavity of the shell 1, in the rubber coating process, the soft rubber is wrapped outside the end surface of the shell 1 penetrated by the pins 2 and the clamping pins 3, and the fasteners 4 are wrapped at the same time, and after the soft rubber is shaped, the soft rubber is adhered with the shell 1;

compared with the design that the outer wall of the shell 1 is flat in the prior art, the design can be buckled with the rubber coating through the plurality of fasteners 4, when the rubber coating is pulled, the plurality of fasteners 4 apply reverse acting force to the rubber coating, so that the connection stability between the rubber coating and the shell 1 is improved, the separation phenomenon of the rubber coating and the outer wall of the shell 1 is slowed down, and the tightness and the safety are indirectly improved;

further optimize, all chamfer the fillet with two edges that are parallel to each other of a plurality of fastener 4 towards the side of casing 1 outer wall, so the design can further increase the flexible glue between fastener 4 and the casing 1 outer wall, the area of contact of flexible glue and fastener 4 further increases simultaneously, indirectly improved the connection stability of flexible glue and fastener 4, the round that the fillet formed compares with the design that flexible glue closed and the design that the edge cut off easily can slow down the flexible glue and take place cracked phenomenon because of the traction, further improve the connection stability of flexible glue and fastener 4.
