Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an assembled waterproof connector. Background Art

[0002] Waterproof connectors are designed to withstand water and maintain their internal mechanical and electrical properties while maintaining a certain level of water pressure. They are widely used in a wide range of applications, including LED streetlights, lighthouses, cruise ships, sprinkler trucks, industrial equipment, automation equipment, and military applications.

[0003] Common environmental performance indicators of waterproof connectors include temperature resistance, moisture resistance, salt spray resistance, vibration resistance and impact resistance.

[0004] Some existing waterproof connectors use sealing rings, typically embedded between the terminal and the housing. These rings are prone to slippage, creating gaps in the housing, allowing water to enter and corrode the terminals, shortening their service life. Other solutions use internal glue to achieve sealing, but these have the disadvantages of lower production efficiency and the risk of glue contaminating the terminal contact surface. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the main purpose of the present invention is to provide an assembled waterproof connector with good waterproof performance, high production efficiency and the ability to avoid glue contamination of the terminal contact surface after glue filling.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled waterproof connector, comprising a male plastic shell, a male terminal module and a tail cover, wherein the two ends of the male plastic shell are respectively provided with a terminal compartment and a sealing compartment, the male terminal module comprises a male terminal, a wire connected to the male terminal and an inner waterproof ring covering the connection between the male terminal and the wire, the male terminal passes through the sealing compartment of the male plastic shell and is inserted into the terminal compartment, the inner waterproof ring and the wire are inserted into the sealing compartment, the wire passes through the tail cover, and a snap boss is provided on the outer wall of the male plastic shell for clamping with the tail cover, and the tail cover squeezes the inner waterproof ring into sealing contact with the inner wall of the sealing compartment.

[0007] Preferably, a limit retaining ring is provided on the outer wall of the male plastic shell, and an outer waterproof ring is provided on the left side of the limit retaining ring.

[0008] Preferably, a connector fixing base connected to a limiting retaining ring is sleeved on the outer wall of the male plastic shell.

[0009] Preferably, the inner cavity of the male plastic shell is concave to form a blocking groove, and the male terminal is provided with an anti-drop barb that is stuck in the blocking groove.

[0010] Preferably, the male plastic shell is further provided with a TPA retaining block that can abut against the male terminal.

[0011] Compared with the prior art, the present invention has the following advantages: during installation, the wires and terminals are pre-connected, the wires pass through the inner waterproof ring, and the wires are fixed to the inner waterproof ring. The terminal is inserted from the sealed compartment into the terminal extension compartment until the terminal enters the terminal extension compartment so that the anti-detachment barb is pressed against the blocking groove. At this time, the inner waterproof ring is embedded in the sealed compartment of the male end housing, and the tail cover is clamped on the snap boss on the outer wall of the male plastic shell from the left side so that the male plastic shell and the tail cover are clamped and fixed, and the tail cover is pressed against the inner waterproof ring to prevent the inner waterproof ring from detaching, thereby forming a waterproof connector. When installing the waterproof connector, the male plastic shell is passed through the connector fixing base, and the connector fixing base and the limit retaining ring press the outer sealing ring tightly so that the gap between the male plastic shell and the outer wall of the connector fixing base is covered to avoid water leakage, and then the connector fixing base and the limit retaining ring are connected by screws.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1As shown, an assembled waterproof connector includes a male plastic shell 1, a male terminal module 2 and a tail cover 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 2 includes a male terminal 6, a wire 7 connected to the male terminal 6, and an inner waterproof ring 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 inner waterproof ring 8 and the wire 7 are inserted into the sealing compartment 5. The wire 7 passes through the tail cover 3. A snap boss 15 that is engaged with the tail cover 3 is provided on the outer wall of the male plastic shell 1. The tail cover 3 squeezes the inner waterproof ring 8 to make sealing contact with the inner wall of the sealing compartment 5.

[0019] The present invention provides an assembled waterproof connector. When installing, the wire 7 and the terminal are pre-connected, the wire 7 passes through the inner waterproof ring 8, and the wire 7 is fixed to the inner waterproof ring 8. The terminal is inserted from the sealed compartment 5 into the terminal extension compartment until the terminal enters the terminal extension compartment, so that the anti-detachment barb 13 is pressed against the blocking groove 12. At this time, the inner waterproof ring 8 is embedded in the sealed compartment 5 of the male end shell, and the tail cover 3 is clamped on the snap boss 15 on the outer wall of the male plastic shell 1 from the left side, so that the male plastic shell 1 and the tail cover 3 are clamped and fixed, and the tail cover 3 is pressed against the inner waterproof ring 8 to prevent the inner waterproof ring 8 from detaching, thus forming a waterproof connector. When installing the waterproof connector, the male plastic shell 1 is passed through the connector fixing base 11, and the connector fixing base 11 and the limit retaining ring 9 press the outer sealing ring tightly, so that the gap between the male plastic shell 1 and the outer wall of the connector fixing base 11 is covered to prevent water leakage, and then the connector fixing base 11 and the limit retaining ring 9 are connected by screws.
