Description

Technical Field

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

[0002] A male-female connector cable is an electrical connection assembly consisting of a matching male and female connector. The male connector has pins, and the female connector has corresponding sockets. Circuit continuity is achieved by inserting the pins into the sockets. It is widely used in outdoor lighting, industrial equipment, water transportation vehicles, and electrical equipment with high waterproofing requirements.

[0003] Existing male-female connector cables generally have poor waterproofing performance at the interface. When the male and female connectors are connected, due to design flaws in the sealing structure at the interface, moisture can easily seep in through the gaps, leading to faults such as short circuits and corrosion in the internal circuitry. For example, in outdoor environments, rainwater, dew, and other liquid water can seep in through the interface, affecting the normal electrical connection of the male-female connector cable and even damaging the connected equipment in severe cases. Furthermore, the connection between the cable and the male-female connector is prone to detachment. During daily use, due to external forces such as pulling, vibration, and bending, the connection between the cable and the connector is prone to loosening or even complete detachment. For example, in industrial production, frequent equipment movement and cable dragging can subject the cable and connector connection to significant external forces, resulting in an unstable connection, affecting the normal operation of the equipment, and potentially causing safety hazards. Utility Model Content

[0004] In view of the problems existing in the current waterproof male and female connector cable, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a waterproof male and female connector cable, which solves the problem that the existing male and female connector cables have poor waterproof performance at the connection point, allowing moisture to easily penetrate from the interface gaps, and are easily affected by external forces such as pulling, causing the connection between the cable and the connector to loosen or even completely fall off, affecting the use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof male and female connector cable includes a cable body, with a male connector and a female connector fixedly connected to one end of the cable body at both ends. The male connector and the female connector are each composed of a protective shell end, a plug end, and a cable sealing end. The plug end is fixedly connected to one end of the protective shell end, and the cable sealing end is fixedly connected to the other end of the protective shell end.

[0008] The male connector has a threaded sleeve fitted on its outer wall, and the female connector has a threaded tube fitted on its outer wall. An external snap-fit ​​sealing rubber ring is fixedly connected to one end of the male connector, and an internal snap-fit ​​sealing rubber ring is fixedly connected to the inner side wall of the threaded tube. The threaded sleeve and the threaded tube are threadedly connected. The external and internal snap-fit ​​sealing rubber rings are positioned correspondingly. One end of the cable sealing end at both ends is fixedly connected to a limit ring through an anti-detachment mechanism. The limit rings at both ends correspond to the positions of the threaded sleeve and the threaded tube, respectively.

[0009] Preferably, the anti-detachment mechanism includes a locking threaded tube, a locking threaded sleeve, and an elastic retainer. Both ends of the cable sealing end are fixedly connected to the locking threaded tube and threaded to the locking threaded sleeve. An elastic retainer is engaged between the locking threaded tube and the locking threaded sleeve.

[0010] Preferably, a waterproof potting compound layer is provided between the cavity of the cable sealing end at both ends and the surface of the cable body.

[0011] Preferably, both the connecting threaded sleeve device and the connecting threaded pipe device have anti-slip grooves on their surfaces.

[0012] Furthermore, one end of the elastic sleeve is tapered, and a rubber sealing ring is engaged between the elastic sleeve and the locking threaded tube.

[0013] Preferably, the surfaces of the male and female connectors are provided with an anti-corrosion nickel-plated coating.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model utilizes a male and female connector consisting of a protective shell end, a plug end, and a cable sealing end. The threaded sleeve device on the outer wall of the male connector is threadedly connected to the threaded tube device on the outer wall of the female connector. While locking the male and female connectors, the internal outer and inner locking sealing rubber rings interlock to form a double sealing barrier, effectively preventing moisture from entering through the interface gaps. Furthermore, a waterproof potting compound layer is provided at the connection between the cable sealing end and the cable body, further ensuring the waterproof performance of the entire connector. This solves the problem of poor waterproof performance at the interface of existing male and female connectors, ensuring stable operation in humid or even underwater environments.

[0016] 2. This utility model utilizes an anti-detachment mechanism consisting of a locking threaded tube, a locking threaded sleeve, and an elastic retainer. When the locking threaded sleeve engages with the locking threaded tube and moves inward, it causes the elastic retainer to contract inward, tightly fixing it to the surface of the cable body. This strengthens the connection between the cable body and the male and female connectors. At the same time, the limiting rings fixedly connected to the sealed ends of the cables at both ends through the anti-detachment mechanism correspond to the positions of the connecting threaded sleeve device and the connecting threaded tube device, effectively preventing the male and female connectors from detaching before locking. This effectively solves the problem that existing male and female connector cables are easily pulled by external forces, causing the cables and connectors to loosen or even detach, thus ensuring the stability and reliability of the electrical connection.

[0017] 3. This utility model utilizes an anti-corrosion nickel-plated coating on the surfaces of the male and female connectors. The nickel-plated coating has good chemical stability and corrosion resistance, effectively resisting oxidation, acid and alkali corrosion, and extending the service life of the male and female connectors. The anti-slip grooves on the surfaces of the connecting threaded sleeve device and the connecting threaded tube device increase surface friction, making it easier for users to rotate and operate, and reducing connection damage caused by inconvenient operation. The rubber sealing ring that snaps between the elastic sleeve and the second threaded tube not only strengthens the sealing protection, but also reduces the wear caused by friction.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a waterproof male and female connector cable.

[0027] This utility model provides, for example Figure 1-4 The waterproof male and female connector cable shown includes a cable body 1. One end of the cable body 1 is fixedly connected to a male connector 2 and a female connector 3 respectively. Both the male connector 2 and the female connector 3 are composed of a protective shell end 4, a plug end 5 and a cable sealing end 6. One end of the protective shell end 4 is fixedly connected to the plug end 5, and the other end of the protective shell end 4 is fixedly connected to the cable sealing end 6.

[0028] The male connector 2 has a threaded sleeve 7 fitted onto its outer wall, and the female connector 3 has a threaded tube 8 fitted onto its outer wall. An external snap-fit ​​sealing rubber ring 9 is fixedly connected to one end of the male connector 2, and an internal snap-fit ​​sealing rubber ring 10 is fixedly connected to the inner wall of the threaded tube 8. The threaded sleeve 7 and the threaded tube 8 are threadedly connected. The external snap-fit ​​sealing rubber ring 9 and the internal snap-fit ​​sealing rubber ring 10 are positioned correspondingly. One end of the cable sealing end 6 at both ends is fixedly connected to a limit ring 11 via an anti-detachment mechanism. The limit rings 11 at both ends correspond to the positions of the threaded sleeve 7 and the threaded tube 8, respectively. The male connector 2 and the female connector 3, composed of a protective shell end 4, a plug-in end 5, and a cable sealing end 6, are connected by plugging the plug-in end 5 of the male connector 2 into the plug-in end 5 of the female connector 3. The connection is achieved by using the threaded sleeve 7 fitted onto the outer wall of the male connector 2. The threaded sleeve device 7 is threadedly connected to the connecting threaded tube device 8, which is sleeved on the outer wall of the female connector 3, to lock the male connector 2 and the female connector 3 after insertion. At the same time, the internal outer locking sealing rubber ring 9 and inner locking sealing rubber ring 10 are interlocked to strengthen the waterproof protection at the connection. The limiting ring 11, which is fixedly connected by the anti-detachment mechanism, limits the connection threaded sleeve device 7 and the connecting threaded tube device 8 at both ends to prevent them from falling off before locking. The anti-detachment mechanism strengthens the connection between the two ends of the wire body 1 and the male connector 2 and female connector 3 at their respective ends, preventing them from falling off. This solves the problem that the existing male and female connector connection ports have poor waterproof performance, and water can easily enter from the interface gaps. They are also easily affected by external pulling and other factors, which can cause the connection between the cable and the connector to loosen or even fall off completely, affecting the use.

[0029] To strengthen the connection between the two ends of line 1, such as Figure 1-4As shown, the anti-detachment mechanism includes a locking threaded tube 12, a locking threaded sleeve 13, and an elastic retainer 14. Both ends of the cable sealing end 6 are fixedly connected to the locking threaded tube 12, and the locking threaded sleeve 13 is threadedly connected to it. An elastic retainer 14 is engaged between the locking threaded tube 12 and the locking threaded sleeve 13. By using the anti-detachment mechanism composed of the locking threaded tube 12, the locking threaded sleeve 13 engages with the locking threaded tube 12 and moves inward, which drives the inner elastic retainer 14 to move inward as well. When moving, the elastic retainer 14 deforms and contracts inward by squeezing against the inner wall of the locking threaded tube 12, thus securing the surface of the cable body 1, thereby strengthening the connection between the two ends of the cable body 1 and preventing the two ends of the cable body 1 from detaching from the male connector 2 and the female connector 3.

[0030] To provide a seal and protection at the connection between the cable sealing end 6 and the cable body 1, such as Figure 3 As shown, a waterproof potting compound layer 15 is provided between the cavity of the cable sealing end 6 at both ends and the surface of the cable body 1. The waterproof potting compound layer 15 is used to seal and protect the connection between the cable sealing end 6 and the cable body 1.

[0031] To increase the surface friction between the threaded sleeve device 7 and the threaded pipe device 8, and to facilitate rotation, such as... Figure 1-3 As shown, both the threaded sleeve device 7 and the threaded tube device 8 have anti-slip grooves 16 on their surfaces. The anti-slip grooves 16 increase the surface friction between the threaded sleeve device 7 and the threaded tube device 8, making it easier to rotate.

[0032] To enhance sealing and protection, such as Figure 2-4 As shown, one end of the elastic sleeve 14 is a tapered surface, and a rubber sealing ring 17 is engaged between the elastic sleeve 14 and the locking threaded tube 12. The rubber sealing ring 17 is used to strengthen the sealing protection between the elastic sleeve 14 and the locking threaded tube 12.

[0033] Finally, to increase the corrosion resistance of male connector 2 and female connector 3, such as Figure 1-3 As shown, the surfaces of male connector 2 and female connector 3 are provided with an anti-corrosion nickel-plated coating. The anti-corrosion nickel-plated coating increases the corrosion resistance of male connector 2 and female connector 3 and extends their service life.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
