[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a glue-potting sealed waterproof connector includes a male plastic shell 1, a connector mounting base 2 and a male terminal module 3; the two ends of the male plastic shell 1 are respectively provided with a terminal compartment 4 and a sealing compartment 5, the male terminal module 3 includes a male terminal 6, a wire 7 connected to the male terminal 6 and a low-pressure injection-molded soft rubber plate 8 covering the connection between the male terminal 6 and the wire 7, the male terminal 6 passes through the sealing compartment 5 of the male plastic shell 1 and is inserted into the terminal compartment 4, the low-pressure injection-molded soft rubber plate 8 and the wire 7 are inserted into the sealing compartment 5, and the gap between the low-pressure injection-molded soft rubber plate 8 and the sealing compartment 5 is filled with a sealing rubber layer that can cover the low-pressure injection-molded soft rubber plate 8.

[0018] This solution features a potting-type sealed waterproof connector. The male connector is divided into a male connector plastic housing 1, a male terminal 6, a wire 7, and a low-pressure injection-molded soft plastic board 8. During installation, the male terminal 6 is inserted through the sealing compartment 5 and into the terminal compartment 4. The low-pressure injection-molded soft plastic board 8 is then inserted into the sealing compartment 5. A layer of sealant is injected into the sealing compartment 5, connecting the male connector plastic housing 1 and the low-pressure injection-molded soft plastic board 8 as one. This ensures good overall sealing and a strong structure. The waterproof rating reaches IP67.

[0019] Preferably, a plurality of slender positioning ribs 9 that can contact the low-pressure injection molding soft rubber plate are provided on the inner wall of the sealing chamber 5.

[0020] The function of the slender positioning ribs 9 is to reduce the friction when the low-pressure injection molded soft rubber plate 8 is inserted, and the positioning is reliable through an appropriate interference fit with the low-pressure injection molded soft rubber plate 8.

[0021] Preferably, a transition step 10 for limiting the low-pressure injection molding soft rubber plate 8 is provided in the sealing chamber 5 .

[0022] The step transition reserves a small gap to prevent the sealant layer from leaking out.

[0023] Preferably, the outer surface of the low-pressure injection molding soft rubber plate 8 is provided with a plurality of annular grooves 11 .

[0024] The design of the annular groove 11 can increase the firmness of the combination between the sealing rubber layer and the low-pressure injection-molded soft rubber plate 8 .

[0025] Preferably, the connector mounting base 2 is sleeved on the outer wall of the male plastic shell 1 , and a shell sealing ring 12 is provided between the connector mounting base 2 and the male plastic shell 1 .

[0026] The housing sealing ring 12 can increase the connection firmness and sealing performance between the connector mounting base 2 and the male plastic housing 1 .

[0027] Preferably, a buckle boss 13 is provided on the outer wall of the male plastic shell 1 to abut against and fix the connector mounting base 2. The buckle boss 13 can ensure that the connector mounting base 2 and the male plastic shell 1 are firmly fixed.

[0028] During production, the low-pressure injection-molded soft rubber plate 8 is pre-molded on the male terminal 6, and the male terminal 6 is connected to the wire 7. The male terminal 6 is inserted into the male plastic shell 1, and the male terminal 6 passes through the sealed chamber 5 and enters the terminal chamber 4. The low-pressure injection-molded soft rubber plate 8 stays in the sealed chamber 5, and the left end of the low-pressure injection-molded soft rubber plate 8 is pressed against the transition step 10. At this time, the gap between the periphery of the low-pressure injection-molded soft rubber plate 8 and the inner wall of the sealed chamber 5 is 0.5mm. After the low-pressure injection-molded soft rubber plate 8 is fully inserted into the sealed chamber 5 of the male shell, the right wall of the low-pressure injection-molded soft rubber plate 8 is 0.5mm away from the right side wall of the male plastic shell 1 (used to cover the right wall of the low-pressure injection-molded soft rubber plate 8). Sealant is injected into the sealed chamber 5 of the male shell. The sealant covers the periphery of the low-pressure injection-molded soft rubber plate 8 and completely surrounds the right side wall of the low-pressure injection-molded soft rubber plate 8 to form a sealant layer.

[0029] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
