Description

Technical Field

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

[0002] In various electronic systems, connectors are used to make electrical connections and transmit signals between devices, components, and systems, and are essential basic components for a complete system. Connectors are widely used in various usage scenarios, but in harsh environments, they must be installed in sealed boxes to meet the IP67 waterproof rating. If used in non-sealed boxes, they cannot meet the IP67 waterproof rating requirements and cannot meet the diverse, multi-environment application scenarios of customers.

[0003] In order to achieve IP67 waterproof level, the existing waterproof process is still the external glue process, that is, to achieve waterproof requirements by filling the connector tail with glue. However, the glue filling process has many problems such as high cost, complex process, low efficiency, poor stability, short product life cycle, and waterproof failure in the later stage. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a waterproof connector, which solves the waterproof problem of the connector in a non-sealed environment. It also reduces costs and avoids many problems such as connector scrapping due to glue leakage, low efficiency, poor stability, short product life cycle, and waterproof failure in the later stage.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a waterproof connector, including a connector, the connector including a body, a first flange is arranged at the middle and lower part of the body, a threading device is arranged inside the body, and the threading device includes multiple threading tubes; a sealing member is provided on the outer side of the connector, a second flange matching with the first flange is provided at the tail of the sealing member, and a sealing hole matching with the multiple threading tubes is provided at the top of the sealing member.

[0006] As a preferred technical solution of the utility model: a first waterproof rib is arranged inside the sealing member.

[0007] As a preferred technical solution of the utility model: a second waterproof rib is arranged in the sealing hole.

[0008] As a preferred technical solution of the present utility model: a groove is provided on the first flange, and the second flange is engaged in the groove.

[0009] As a preferred technical solution of the present invention: a pressure plate is clamped on the outer sides of the first flange and the second flange.

[0010] As a preferred technical solution of the utility model: claws are arranged around the pressing plate.

[0011] The utility model has the following beneficial effects:

[0012] 1. The sealant replaces the original glue filling process and uses glue as the sealing carrier, which solves the waterproof problem of the connector in a non-sealed environment. It also reduces costs and avoids many problems such as connector scrapping, low efficiency, poor stability, short product life cycle, and waterproof failure in the later stage due to glue leakage.

[0013] 2. The setting of the second waterproof rib can restrain the deformation of the wire during the pulling process, thereby avoiding the problem of waterproof failure due to the pulling of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is further described in detail in conjunction with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] like Figure 1-Figure 5As shown, the embodiment of the utility model provides a waterproof connector, including a connector 1, the connector 1 includes a body 2, a first flange 3 is arranged at the middle and lower part of the body 2, a threading device 4 is arranged inside the body 2, the threading device 4 is connected with the body 2 in one piece, and good sealing is ensured, the threading device 4 includes a plurality of threading tubes 5, the number of which is set according to the number of electrode terminals used on site, and two threading tubes 5 are preferably used in this embodiment; it can be understood that the threading device 4 can also be connected to the body 2 in an active manner, that is, the threading device 4 is arranged in the body 2 in a snap-on manner. A sealing member 6 is sleeved on the outer side of the connector 1, a second flange 7 matching the first flange 3 is arranged at the tail of the sealing member 6, and a sealing hole 8 matching the threading tube 5 is arranged at the top. The size of the sealing hole 8 is determined according to the wire diameter of the wire when in use, and the sealing hole 8 ensures the sealing of the connector 1. The seal 6 replaces the original glue filling process and uses glue as a sealing carrier, which solves the waterproof problem of the connector 1 in a non-sealed environment, reduces costs, and avoids many problems such as connector scrapping due to glue leakage, low efficiency, poor stability, short product life cycle, and waterproof failure in the later stage.

[0022] In order to increase the waterproof effect, a plurality of first waterproof ribs 9 are arranged inside the seal 6, and the plurality of first waterproof ribs 9 increase the waterproofness between the seal 6 and the connector 1. A plurality of second waterproof ribs 10 are arranged on the sealing hole 8, and the plurality of second waterproof ribs 10 can constrain the deformation of the wire during the pulling process, thereby avoiding the problem of waterproof failure due to the pulling of the wire.
