Description

Technical Field

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

[0002] A connector is a structure that connects lines or lines to devices. Its function is to bridge the gap between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve its intended function. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc.

[0003] Currently, the waterproof structure of most connectors is relatively complex, the assembly process is complicated, the manufacturing cost is high, and the entire connector needs to be replaced after damage, which increases the subsequent investment cost and is not conducive to market promotion.

[0004] Chinese utility model patent CN219498310U discloses a waterproof structure and connector of a connector mesh tail, which relates to the technical field of connector structure, including a waterproof baffle, which is sleeved with the connector terminal, and the waterproof baffle is used to cover the connection port and prevent liquid from penetrating into the terminal plug-in place; a waterproof installation step is arranged at the connector terminal; wherein the waterproof installation step is provided with a fixing nut, and the fixing nut is screwed with the waterproof installation step. According to the waterproof structure and connector of the connector mesh tail of the utility model, the waterproof baffle is sleeved on the waterproof installation step. When the connector terminal is connected to the socket, the waterproof baffle can cover the socket port and prevent external liquid from splashing or penetrating into the terminal. The structure is simple, dustproof, waterproof and splashproof, and can also improve the bending resistance of the wire. When the waterproof baffle needs to be replaced, it only needs to loosen the fixing nut and replace the new waterproof baffle. The connector body can continue to be used, reducing the later maintenance cost.

[0005] It also solves the problem of complicated assembly of waterproof structure and overall replacement after damage, but still has the following defects:

[0006] 1. The sealing configuration is only performed by tightening the sealing ring with a nut, and the waterproof platform is sealed. The sealing performance is poor. Long-term use and aging of the sealing ring will lead to poor sealing and affect the waterproof effect.

[0007] 2. The water baffle is matched with the connector and terminal, and cannot be applied to a variety of connectors, so the scope of application is limited;

[0008] 3. The connection between the anti-bending part and the water retaining plate only relies on the extrusion of the assembly, and the sealing effect is poor. Summary of the invention

[0009] Technical problems to be solved by the utility model

[0010] The sealing configuration that only uses a nut to tighten the sealing ring and a waterproof platform for sealing has poor sealing performance. Long-term use and aging of the sealing ring will lead to poor sealing and affect the waterproof effect. The water retaining plate matches the connector and the terminal and cannot be applied to a variety of connectors, so the scope of application is limited. The connection between the anti-bending part and the water retaining plate only relies on assembly extrusion, and the sealing effect is poor.
