Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a waterproof female connector. Background Technology

[0002] In modern electronic devices and electrical systems, connectors, as key components for achieving reliable connections between circuits, are widely used in industrial control, automotive electronics, outdoor communication equipment, smart homes, and consumer electronics. Female connectors are typically fixedly mounted on device housings, circuit boards, or cables to receive male pins for signal or power transmission. Because they are exposed to the external environment, especially in humid, rainy, high-humidity, or cleaning-required environments, moisture can easily seep into the connector, leading to short circuits, corrosion, and decreased insulation performance, severely impacting the normal operation and lifespan of the equipment.

[0003] Traditional connector designs often prioritize electrical performance and mechanical mating life, with relatively insufficient consideration for waterproof sealing. Common solutions involve using simple rubber gaskets or potting compounds for localized protection, but these methods frequently suffer from poor sealing, susceptibility to aging, and difficulty in disassembly and reassembly. Especially in applications with frequent mating and unmating, dynamic sealing is difficult to guarantee, and moisture can still seep in along interface gaps, leading to rapid failure of waterproofing performance. Utility Model Content

[0004] This utility model provides a waterproof female connector that achieves a "front-blocking and rear-cutting" waterproof mechanism through an internal sealing first gasket and an end-face sealing second gasket. The connector is reinforced with a connecting piece to increase the tightness of the connection, thus solving the problem mentioned in the background art that the sealing structure is simple and prone to poor sealing.

[0005] This utility model provides the following technical solution:

[0006] A waterproof female connector includes a female head and a male head that are mutually compatible, and further includes: a first sealing gasket and a second sealing gasket in an annular structure, both mounted on the female head, wherein the outer wall of the first sealing gasket abuts against the inner wall of the male head for internal sealing, and the side wall of the second sealing gasket abuts against the end face of the male head for end face sealing; a connector mounted on the female head for fixing the male head and the female head; and a protective sleeve mounted on the female head, which is fitted over the connecting end of the female head when the male head is not inserted.

[0007] As a preferred embodiment of the present invention, the outer wall of the first sealing gasket is provided with a plurality of annular grooves, and the plurality of annular grooves are equidistantly distributed along the axis of the first sealing gasket.

[0008] As a preferred embodiment of this utility model, the depth of the annular groove ranges from 0.3 to 1.5 mm, and the width ranges from 1 to 3 mm.

[0009] As a preferred embodiment of the present invention, the second sealing gasket has a groove with an annular structure on its side wall. The groove has a depth range of 1-3 mm and a width less than or equal to one-third of the width of the second sealing gasket.

[0010] As a preferred embodiment of this utility model, the connector includes a threaded sleeve rotatably connected to the outer wall of the female head, and the inner wall of the threaded sleeve is threadedly connected to the outer wall of the male head.

[0011] As a preferred embodiment of this utility model, a third sealing gasket is installed on the female head, and the side wall of the third sealing gasket abuts against the inner wall of the threaded sleeve.

[0012] As a preferred embodiment of this utility model, one end of the protective sleeve is rotatably connected to a first connecting ring, and the outer wall of the threaded sleeve is rotatably connected to a second connecting ring. The first connecting ring is fixedly connected to the first connecting ring by a pull rope.

[0013] As a preferred embodiment of this utility model, the outer wall of the female connector is provided with a guide groove to prevent errors when connecting the male connector.

[0014] Compared with the prior art, this utility model provides a waterproof female connector, which has the following advantages:

[0015] 1. In this waterproof female connector, by installing a first sealing gasket and a second sealing gasket on the female head, the internal and end face can be sealed simultaneously when the male head or protective sleeve is connected to the female head, realizing a "front blocking and rear cutting" waterproof mechanism. Even if the outer layer is damaged, the inner layer can still maintain basic waterproof function, thus improving the sealing effect.

[0016] 2. In this waterproof female connector, multiple annular grooves are formed on the first sealing gasket to create a sawtooth structure, which improves elasticity, reduces assembly force, and enhances environmental adaptability while ensuring sealing performance.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model achieves a "front blocking and rear interception" waterproof mechanism by combining internal sealing and end face sealing to prevent loosening, which can significantly improve the waterproof effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Reference Figures 1-4A waterproof female connector includes a female head 1 and a male head 2 that are mutually adapted, and further includes a first sealing gasket 4 and a second sealing gasket 5 in a circular annular structure, both of which are installed on the female head 1. The female head 1 has a connecting post and a baffle. A first sealing groove is formed on the circumference of the connecting post, and the first sealing gasket 4 is fitted inside the first sealing groove. A second sealing groove is formed on the end face of the baffle near the connecting post, and the second sealing gasket 5 is installed inside the second sealing groove. When the male connector 2 is inserted into the female connector 1, the outer wall of the first sealing gasket 4 abuts against the inner wall of the male connector 2 for internal sealing. Simultaneously, the end face of the male connector 2 approaches the baffle, and the side wall of the second sealing gasket 5 abuts against the end face of the male connector 2 for end-face sealing. A connector is installed on the female connector 1 to secure the male connector 2 to the female connector 1. When the male connector 2 is inserted into the female connector 1, the connector reinforces the connection between them, preventing loosening and ensuring that the male connector 2 is in contact with the first and second sealing gaskets 4 and 5, thus improving waterproofing. A protective sleeve 6 is installed on the female connector 1. When the male connector 2 is not inserted, the protective sleeve 6 is fitted over the connection end of the female connector 1. The outer wall of the first sealing gasket 4 abuts against the inner wall of the protective sleeve 6, and the side wall of the second sealing gasket 5 abuts against the end face of the protective sleeve 6 for end-face sealing, providing dustproof and waterproof protection, improving service life and safety.

[0027] When in use, by installing the first sealing gasket 4 and the second sealing gasket 5 on the female connector 1, the internal and end face can be sealed simultaneously when the male connector 2 or the protective sleeve 6 is connected to the female connector 1, realizing a "front blocking and rear cutting" waterproof mechanism. Even if the outer layer is damaged, the inner layer can still maintain basic waterproof function, thus improving the sealing effect.

[0028] The outer wall of the first sealing gasket 4 has multiple annular grooves 401, with two to five grooves, preferably three, forming a "serrated" structure. The annular grooves 401 are equidistantly distributed along the axis of the first sealing gasket 4. The depth of the annular grooves 401 ranges from 0.3 to 1.5 mm, and the width ranges from 1 to 3 mm. Here, the depth is 0.8 mm and the width is 1.5 mm. During use, by creating multiple annular grooves 401 on the first sealing gasket 4, stress can be absorbed through elastic deformation at the peaks and troughs under pressure, and the gasket rebounds rapidly after release. Compared to solid O-rings, it is less prone to "permanent flattening" under long-term compression, making it suitable for long-term sealing applications. Furthermore, each tooth can deform independently, achieving "multi-point contact" or "progressive sealing." Even with slight unevenness or tolerance deviations on the mating surfaces, each tooth can adaptively fit, improving sealing reliability and reducing leakage caused by local gaps. In addition, it can reduce assembly force and improve the insertion and removal feel. In applications such as connectors that require frequent insertion and removal, the serrated sealing gasket only needs to overcome the deformation force of a single serration during initial compression. The total pressing force is much lower than that of a solid sealing ring, which significantly reduces insertion and removal force and improves the user experience.

[0029] A ring-shaped groove 501 is formed on the side wall of the second sealing gasket 5. The depth of the groove 501 ranges from 1 to 3 mm, and the width is less than or equal to one-third of the width of the second sealing gasket 5. Here, the depth is 1.5 mm, the width of the second sealing gasket 5 is 8 mm, and the width of the groove 501 is 2.5 mm. In use, by forming the groove 501 on the second sealing gasket 5, when the side wall of the second sealing gasket 5 abuts against the end face of the male connector 2, as the male connector 2 gradually approaches the female connector 1, the second sealing gasket 5 tends to collapse inward, causing the air in the groove 501 to be discharged outward, forming a vacuum state, which can be adsorbed onto the end face of the male connector 2, thereby improving the sealing effect between the second sealing gasket 5 and the male connector 2.

[0030] The connector includes a threaded sleeve 3 rotatably connected to the outer wall of the female connector 1. The inner wall of the threaded sleeve 3 is threadedly connected to the outer wall of the male connector 2, which not only has an anti-loosening effect but also ensures the abutment state between the male connector 2 and the first sealing gasket 4 and the second sealing gasket 5. When the male connector 2 is not connected to the female connector 1, a protective sleeve 6 is fitted onto the female connector 1, and the outer wall of the protective sleeve 6 is threadedly connected to the inner wall of the threaded sleeve 3. Of course, in other embodiments, the connector can be a pin, a snap-fit, or other fastener.

[0031] A third sealing gasket is installed on the female connector 1. That is, a third sealing groove is opened on the end face of the baffle away from the connecting post. The third sealing gasket is installed in the third sealing groove. After the threaded sleeve 3 connects to the male connector 2, the side wall of the third sealing gasket abuts against the inner wall of the threaded sleeve 3. Through the threaded structure and the third sealing gasket, water can be further reduced from entering the connection between the male connector 2 and the female connector 1, thus improving the waterproof effect.

[0032] A first connecting ring 601 is rotatably connected to one end of the protective sleeve 6, and a second connecting ring 602 is rotatably connected to the outer wall of the threaded sleeve 3. The first connecting ring 601 is fixedly connected to the first connecting ring 601 by a pull rope 603, which reduces the problem of the protective sleeve 6 being lost.

[0033] A guide groove 101 is provided on the outer wall of the female connector 1. The guide groove 101 extends along the axis of the female connector 1. When the male connector 2 is inserted into the female connector 1, it is used to prevent incorrect connection of the male connector 2, reduce the occurrence of incorrect insertion direction of the male connector 2, and improve the connection accuracy.

[0034] Components not described in detail in this article are existing technologies.
