Description

Technical Field

[0001] The utility model relates to the field of connectors, and in particular to a new female waterproof connector which only uses a main rubber shell and a sealing ring to achieve a waterproof function, reduces product components and can achieve the same functional requirements. Background Art

[0002] Connectors are important components for vehicle batteries, 5G base stations, and equipment data collection. Each connector needs to be waterproof. Existing waterproof female connectors achieve waterproof function through the main rubber shell and the front cover with a sealing ring. The components are relatively cumbersome and cumbersome. The market is developing rapidly, and existing connectors are in urgent need of streamlining and improvement. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a new female waterproof connector which only uses a main rubber shell and a sealing ring to achieve a waterproof function, reduces product components and can achieve the same functional requirements.

[0004] The technical solution provided by the utility model is: a female waterproof connector, comprising: a main rubber shell, a sealing ring and a CPA lock;

[0005] The main rubber shell is provided with an inner cavity with an opening on one side, and the main rubber shell is provided with an inner concave opening, and the inner concave opening forms a convex step in the inner cavity; the sealing ring is sleeved into the convex step of the inner cavity of the main rubber shell;

[0006] The top of the main plastic shell is provided with a slot, and the CPA lock is inserted into the slot for locking;

[0007] Further optimization, the card slot is provided with a boss, and the CPA lock is provided with a hook and a buckle; the hook is hooked tightly at one end of the card slot for fixation, and the buckle clamps the boss for double fixation;

[0008] Further optimization, the number of the convex steps is not less than 4; and all the convex steps are on the same cross section;

[0009] Further optimized, the convex step presses and fixes the sealing ring.

[0010] Further optimization, the sealing ring is W-toothed, and when the convex step is pressed, the W-toothed sealing ring is adsorbed on the surface of the convex step.

[0011] Compared with the disclosed technical solutions, the innovation of the female waterproof connector of the utility model is that it only uses the main rubber shell and the sealing ring to achieve the waterproof function, which reduces the product components while achieving the same functional requirements. It uses double locking, which can greatly improve the waterproofness and fixation of the product. It effectively ensures the waterproofness and stability without wasting too much raw materials, further saving raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figures 1 to 6 , and specific embodiments are used to describe the present invention in detail, but they are not intended to limit the present invention. Example

[0019] As attached Figures 1 to 6 As shown, a female waterproof connector includes: a main rubber shell 1, a sealing ring 2 and a CPA lock 3;

[0020] The main rubber shell 1 is provided with an inner cavity 11 with an opening on one side, and a concave opening 12 is provided on the main rubber shell 1, and the concave opening 12 forms a convex step 13 in the inner cavity; the sealing ring 2 is inserted into the convex step 13 of the inner cavity 11 of the main rubber shell 1;

[0021] The top of the main plastic shell 1 is provided with a slot 14, and the CPA lock 3 is inserted into the slot 14 for locking;

[0022] The slot 14 is provided with a boss, and the CPA lock 3 is provided with a hook 31 and a buckle 32; the hook 31 is hooked tightly at one end of the slot 14 for fixation, and the buckle 32 is clamped on the boss for double fixation;

[0023] The number of the convex steps 13 is no less than 4, and all the convex steps 13 are on the same cross section;

[0024] The convex step 13 presses and fixes the sealing ring 2 .

[0025] The sealing ring 2 is W serrated, when the convex step 13 is pressed, the W serrated sealing ring 2 is adsorbed on the surface of the convex step 13;

[0026] As attached Figures 1 to 6As shown, a female waterproof connector is implemented as follows: the sealing ring 2 is inserted into the convex step 13 of the inner cavity 11 of the main plastic shell 1, and the CPA lock 3 is inserted into the card slot 14 for locking, the hook 31 is hooked at one end of the card slot 14 for fixing, and the buckle 32 is clamped on the boss for double fixing. In this way, the purpose of the new model is achieved, only the main plastic shell is used with the sealing ring to achieve the waterproof function, and the same functional requirements can be achieved while reducing the product components. The use of double locking can greatly improve the waterproofness and fixation of the product. It effectively ensures waterproofness and stability without wasting too much raw materials, further saving raw materials.

[0027] It is known from common technical knowledge that the technical solution can be implemented by other implementation schemes that do not deviate from its spirit or essential features. Therefore, the above disclosed implementation schemes are only illustrative in all aspects and are not exclusive. All changes within the scope of the utility model or within the scope equivalent to the utility model are included in the utility model.
