[0026] 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.

[0027] This utility model provides, for example Figures 1-6 A quick connector shown includes:

[0028] Male connectors and female connectors;

[0029] The male connector includes a male connector body 1, a plastic shell body 2, and a clamping nut 3. The clamping nut 3 is threaded to one end of the plastic shell body 2, and the end of the plastic shell body 2 away from the clamping nut 3 is threaded to one end of the male connector body 1. The female connector includes a female connector body 4 and a plastic nut 5. The plastic nut 5 is threaded on the outside of the female connector body 4.

[0030] The plastic shell body 2 has shrinkage grooves 6 around the end away from the male connector body 1 to form an elastic shrinkage part 7. A sealing ring 8 is provided inside the plastic shell body 2. The sealing ring 8 is located inside the elastic shrinkage part 7. The inner wall of the tightening nut 3 is pressed and fitted to the outer side of the elastic shrinkage part 7. A waterproof ring 9 is snapped onto the outer side of the female connector body 4. The side of the waterproof ring 9 away from the female connector is fitted to the inner wall of the male connector body 1.

[0031] The male connector body 1 and the female connector body 4 are snapped together at opposite ends. Both the male connector body 1 and the female connector body 4 are provided with metal terminals 10 for connecting to the connecting wire. The male connector body 1 and the female connector body 4 are provided with elastic snap-fit ​​components 11 on their outer sides.

[0032] By setting the internal sealing ring 8 of the plastic shell body 2, after the tightening nut 3 is installed on the plastic shell body 2, the tightening nut 3 squeezes the elastic contraction part 7 to apply pressure to the sealing ring 8, so that the sealing ring 8 seals and fits the connecting wire and the male connector, thus playing a waterproof sealing role. At the same time, the waterproof ring 9 is set on the insertion surface of the female connector body 4 and the male connector body 1, which also serves the purpose of waterproofing and preventing short circuits caused by penetration when the connector is connected.

[0033] Among them, such as Figures 2-3 As shown:

[0034] A waterproof gasket 12 is also fitted on the outer side of the female connector body 4. The waterproof gasket 12 is located on the side of the plastic nut 5 away from the male connector. By setting the waterproof gasket 12, the sealing between the female connector and the electronic device is ensured when the female connector is installed on the electronic device. At the same time, it works with the plastic nut 5 to stably install the female connector on the electronic device.

[0035] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown:

[0036] The elastic snap-fit ​​assembly 11 includes an elastic fastener 111 located on the outside of the female connector body 4. The male connector body 1 has a insertion channel 112 at the end away from the plastic shell body 2. The outer side of the male connector body 1 has a slot 113 that engages with the elastic fastener 111. The slot 113 communicates with the insertion channel 112. A pressing head 114 that can move radially on the male connector body 1 is movably engaged inside the slot 113. The pressing head 114 slides against the elastic fastener 111. By having the elastic fastener 111 pass through the insertion channel 112 and engage with the slot 113, a stable connection between the female connector body 4 and the male connector body 1 is achieved. Subsequently, the pressing head 114 is provided in the slot 113 to facilitate the elastic pressing of the elastic fastener 111 when disassembling the connection, so that the elastic fastener 111 separates from the slot 113, limiting contact and facilitating the separation of the male connector body 1 and the female connector body 4.

[0037] Preferred, such as Figure 3 and Figure 5 As shown:

[0038] The end of the male connector body 1 that is away from the plastic shell body 2 is D-shaped. The insertion channel 112 is located on the plane outside the male connector body 1. By limiting the shape of the inner cavity of the male connector body 1, it is ensured that the internal hardware terminals 10 are accurately aligned after the male connector body 1 and the female connector body 4 are inserted, while avoiding reverse insertion.

[0039] It is worth noting that, such as Figures 3-4 As shown:

[0040] Both the tightening nut 3 and the outer side of the plastic shell body 2 are provided with anti-slip grooves 13, and the outer side of the female connector body 4 is also covered with a protective cover 15. The anti-slip grooves 13 increase the friction of the operator's hand, prevent slippage, and facilitate quick assembly of the connector.

[0041] In a further preferred embodiment, such as Figure 3 and Figure 5 As shown:

[0042] The outer side of the female connector body 4 is provided with a storage groove 14, and the waterproof ring 9 is placed in the storage groove 14. The outer side of the waterproof ring 9 is provided with multiple sets of protrusions 91. The storage groove 14 is provided to prevent the waterproof ring 9 from sliding during the insertion and removal of the male connector body 1 and the female connector body 4. At the same time, the outer side of the waterproof ring 9 is provided with multiple sets of protrusions 91 to better play the role of waterproofing.

[0043] In practical use, one set of connecting wires is connected to the metal terminals 10 on the female connector body 4, and another set of connecting wires passes through the tightening nut 3 and the plastic shell body 2. Simultaneously, the sealing ring 8 is fitted onto the connecting wires. The connecting wires are then connected to the metal terminals 10 on the male connector body 1. The plastic shell body 2 is then threaded onto one end of the male connector body 1. The sealing ring 8 is then moved inside the plastic shell body 2 and positioned inside the elastic contraction portion 7. The tightening nut 3 is then threaded onto one end of the plastic shell body 2. During installation, the tightening nut 3 compresses the elastic contraction portion 7, applying pressure to the sealing ring 8, causing it to fit between the connecting wires and the plastic shell body 2, thus providing a waterproof seal. Simultaneously, the female connector body 4 is threaded through the mounting plate on the electronic device. After drilling the hole, the waterproof gasket 12 is placed between the female connector body 4 and the electronic device. Then, the plastic nut 5 is threaded onto the outside of the female connector body 4 to fix the female connector body 4 in place. Then, the waterproof ring 9 is placed in the storage groove 14. Then, the female connector body 4 and the male connector body 1 are aligned and inserted. Then, the elastic fastener 111 elastically deforms and passes through the insertion channel 112 into the slot 113. The male connector and the female connector are fixedly connected by the engagement of the elastic fastener 111 and the slot 113. When disassembling, simply press the pressing head 114 to squeeze the elastic fastener 111, so that the elastic fastener 111 can be easily removed from the insertion channel 112 to achieve separation.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
