Automotive SCR Urea Tube Quick Connector Solution

In order to overcome the problem that the existing SCR urea tube quick connector assembly and disassembly labor and the sound signal of the male connector are not reliable, the technical solution adopted by STANDARDS to solve the SCR urea tube quick connector technical problem is:

The SCR urea tube quick connector for automobile, comprising a male connector, a snap connector and a female connector, the male connector being a hollow structure penetrating up and down, the male connector comprising a male connector connection tube, a urea inlet connection portion, an annular plate and a ring shape a protrusion, the upper end of the male connector connecting tube is provided with the urea inlet connecting portion, the annular plate is sleeved at an upper middle portion of the male connector connecting tube, and the annular protrusion is disposed under the annular plate a male connector connecting the lower middle portion of the tube; an outer diameter of the annular plate is larger than an outer diameter of the annular protrusion;

The female connector is a hollow structure, and the female connector includes a female connector connecting tube, a locking portion and a urea outlet connecting portion, and the upper end of the female connector connecting tube is provided with the locking portion, and the female connector is connected to the tube The urea outlet connection portion is disposed at a lower end;

The latching member includes a latching portion and a handle portion, the latching portion is provided with a connecting through hole, and the connecting through hole is provided with a semicircular notch on a side away from the handle portion, and the semicircular notch The inner diameter is the same as the outer diameter of the male connector connecting tube; the handle portion is provided with a waist groove, and the length direction of the waist groove is arranged along the moving direction of the fastening member;

The lower end of the male connector connecting tube sequentially passes through the step through hole, the connecting through hole and the center hole of the female connector connecting tube from top to bottom, and the annular protrusion is located on the step of the step through hole, the buckle a piece is located above the annular protrusion, the annular plate is located above the step and is engaged with the step, the engaging portion of the locking member extends into the cavity of the locking portion, and the connecting through hole is a stepped through hole, a central hole of the female connector connecting tube is connected, the positioning post is located in the waist groove and is engaged with the curved end on the waist groove, and the semicircular notch is snapped at the male connector Connect the outer wall of the tube.

Compared with the prior art, the STANDARDS SCR urea tube quick connector fully utilizes the elasticity of the plastic ring and the rubber ring, and installs the sealing assembly between the stopper on the female connector and the step through hole, so that the male connector is inserted and removed during the insertion and removal process. The position of the seal assembly does not move, making the seal reliable. It is more reliable than the existing sound in the assembly factory to judge whether the sound is inserted or not. The snap-on pull-out design is more labor-saving than the transmission of the plastic ring by means of a finger. The waist groove of the fastener is simple and practical, and is convenient and flexible during the locking and relaxing process of the male connector.
