[0030] The utility model is further described below in conjunction with the accompanying drawings.
[0031] like Figure 1 and Figure 2 As shown, a connector with an anti-retraction function includes a male connector 1, a female connector 2, an unlocking wrench 12 and a board-end mounting member. In this embodiment, the male connector 1 adopts a pin structure; the female connector 2 adopts a socket structure). The male connector 1 and the female connector 2 can be plugged together to form an electrical connection.
[0032] The male connector 1 and the female connector 2 each include an insulating shell 3, an anti-retraction gasket 4, a conductive plug connector and a wire end sealing assembly. The two ends of the insulating shell 3 are respectively a plug end and a wiring end. The plug ends of the insulating shells 3 of the male connector 1 and the female connector 2 are respectively provided with mutually matching snap-on structures, which can be plugged together and locked by snapping. The conductive plug connector for forming an electrical connection between two cables is installed in the insulating shell 3. The conductive plug connectors in the male connector 1 and the female connector 2 are respectively a socket 7 and a pin 10 that match each other. When the male connector 1 is docked with the female connector 2, the socket 7 and the pin 10 are plugged together to form an electrical connection.
[0033] like Figure 3 and Figure 4 As shown, the insulating shell 3 is divided into a docking section, a main section, a circumferential limit section, an external thread section and a circle of anti-rotation teeth 1-2 which are sequentially arranged and connected along the direction from the plug end to the wiring end. A stepped limit surface 1-3 is provided between the circumferential limit section and the main section. The docking section is used for docking the male end connector 1 with the female end connector 2. A locking wire sealing ring 8 is installed at the connection between the docking section and the main section of the insulating shell 3 in the male end connector 1; when the male end connector 1 is docked with the female end connector 2, the locking wire sealing ring 8 extends into the inside of the female end connector 2 to achieve sealing at the connection between the male end connector 1 and the female end connector 2.
[0034] like Figure 1 and Figure 5 As shown, the main body of the circumferential limit section is cylindrical, and the side is provided with a first limit surface 1-1 parallel to the axis of the insulating shell 3. The anti-retreat gasket 4 is an irregular annular structure; the inner circumferential surface of the anti-retreat gasket 4 is provided with a second limit surface 4-2 that matches the first limit surface 1-1 on the circumferential limit section. The outer circumferential surface of the anti-retreat gasket 4 is provided with an elastic latch 4-1. The elastic latch 4-1 gradually tilts away from the anti-retreat gasket 4 in the direction from the inside to the outside. The anti-retreat gasket 4 is sleeved on the circumferential limit section, and is circumferentially limited by the first limit surface 1-1 and the second limit surface 4-2.
[0035] like Figure 1 , Figure 6 and Figure 7As shown, the wire end sealing assembly includes a sealing sleeve 9 and an anti-retraction locking nut 11. The main body of the sealing sleeve 9 is in a truncated cone shape; the large diameter end of the sealing sleeve 9 is provided with an embedded ring 9-2 and a circle of anti-rotation grooves 9-1 surrounding the outside of the embedded ring 9-2; the end surface of the embedded ring 9-2 is higher than the top of the anti-rotation groove 9-1; the embedded ring 9-2 can extend into the inner side wall of the insulating housing 3; the circle of anti-rotation grooves 9-1 on the sealing sleeve 9 and the circle of anti-rotation teeth 1-2 at the end of the insulating housing 3 match each other, which can prevent the sealing sleeve 9 from rotating.
[0036] like Figure 7 As shown, the anti-retraction locking nut 11 is conical, and is provided with a conical inner side surface 11-1 arranged in sequence from the small diameter end to the large diameter end, an internal thread 11-2 matching the external thread section on the insulating shell 3, and a circle of anti-retraction grooves 11-3. The internal thread 11-2 in the anti-retraction locking nut 11 is threadedly connected with the external thread section on the insulating shell 3; the conical inner side surface 11-1 of the anti-retraction locking nut 11 presses against the outer side surface of the sealing sleeve 9, so that the circle of anti-rotation grooves 9-1 on the sealing sleeve 9 and the circle of anti-rotation teeth 1-2 at the end of the insulating shell 3 are tightly fitted to form an end face seal; at the same time, the extrusion of the anti-retraction locking nut 11 shrinks the through hole of the small diameter section of the sealing sleeve 9, tightly hugging the cable led out of the conductive plug connector to complete the radial seal.
[0037] A circle of anti-retraction grooves 11-3 in the anti-retraction locking nut 11 surrounds the outer side of the anti-retraction gasket 4; the elastic latch teeth 4-1 on the anti-retraction gasket 4 press against the anti-retraction grooves 11-3 to form a ratchet pawl mechanism; the elastic latch teeth 4-1 can prevent the anti-retraction locking nut 11 from rotating in the loosening direction through the anti-retraction grooves 11-3. Therefore, the elastic latch teeth 4-1 cooperate with the anti-retraction grooves 11-3, so that the anti-retraction locking nut 11 can only rotate in the tightening direction relative to the anti-retraction gasket 4, thereby preventing the anti-retraction locking nut 11 from retreating and loosening during long-term use.
[0038] like Figure 8 As shown, when the anti-retraction locking nut 11 is tightened on the insulating shell 3; a gap is left between the anti-retraction locking nut 11 and the stepped limit surface 1-3 of the insulating shell 3; the unlocking wrench 12 can be inserted into the gap between the anti-retraction locking nut 11 and the stepped limit surface 1-3, squeezing the elastic locking teeth 4-1 on the anti-retraction gasket 4, so that the anti-retraction locking nut 11 can be loosened, thereby realizing the disassembly of the anti-retraction locking nut 11.
[0039] like Fig. 9 , Fig.10 and Fig.11As shown, the board-end mounting part is used when the male-end connector 1 or the female-end connector 2 needs to be connected to the board-end product; the board-end mounting part includes an anti-retraction locking nut 13 and a sealing gasket 5; the inner circumferential surface of the anti-retraction locking nut 13 is provided with an internal thread 11-2 and a circle of anti-retraction grooves 11-3. The circle of anti-retraction grooves 11-3 on the anti-retraction locking nut 13 has the same structure as the circle of anti-retraction grooves 11-3 on the anti-retraction locking nut 11. A third limiting surface 5-1 matching the first limiting surface 1-1 on the circumferential limiting section is provided on the inner circumferential surface of the sealing gasket 5. A fourth limiting surface 6-1 matching the first limiting surface 1-1 on the circumferential limiting section is provided on the mounting hole of the mounting panel 6.
[0040] When the male connector 1 or the female connector 2 needs to be connected to the board-end product; remove the sealing sleeve 9, the anti-retraction locking nut 11 and the anti-retraction gasket 4 from the corresponding insulating shell 3; put the sealing gasket 5 on the circumferential limit section of the insulating shell 3; pass the anti-rotation clamping teeth 1-2, the external thread section and the circumferential limit section of the insulating shell 3 through the mounting hole on the mounting panel 6. Put the anti-retraction gasket 4 on the circumferential limit section of the insulating shell 3 exposed from the mounting hole of the mounting panel 6; then screw the anti-retraction locking nut 13 to the external thread section of the insulating shell 3; a circle of anti-retraction grooves 11-3 on the retreat locking nut 3 surrounds the outside of the anti-retraction gasket 4; the elastic clamping teeth 4-1 on the anti-retraction gasket 4 prevent the anti-retraction locking nut 11 from rotating in the direction of loosening through the anti-retraction grooves 11-3, thereby realizing the anti-retraction function of the board end.
[0041] When the anti-backward locking nut 13 is tightened on the insulating shell 3; a gap is left between the anti-backward locking nut 13 and the installation panel 6; the unlocking wrench 12 can be inserted into the gap between the anti-backward locking nut 13 and the installation panel 6, squeezing the elastic tooth 4-1 on the anti-backward gasket 4, so that the elastic tooth 4-1 is separated from the anti-backward groove 11-3; the anti-backward locking nut 13 can be loosened, thereby realizing the disassembly of the anti-backward locking nut 13.
[0042] The following further provides a specific board end installation method: the insulating shell 3 is combined with the sealing gasket 5 and installed on the installation panel 6 to keep it in close contact. At this time, the first limit surface 1-1 contacts the third limit surface 5-1 and the fourth limit surface 6-1 to limit the axial rotation of the insulating shell 3 and the sealing gasket 5; the anti-retraction gasket 4 is sleeved on the insulating shell 3 and in close contact with the installation panel 6; at this time, the second limit surface 4-2 contacts the first limit surface 1-1 to limit the axial rotation of the anti-retraction gasket 4; the anti-retraction locking nut 13 is installed and tightened, and the elastic tooth 4-1 falls into the anti-retraction groove 11-3 In 3-1, as the torque increases, the elastic latch 4-1 slides in the anti-retraction groove 11-33-1 until the seal is locked; the thickness of the anti-retraction gasket 4 satisfies the condition that there is a gap between the insulating shell 3 and the installation panel 6 after being tightened, thereby reserving unlocking space for the unlocking wrench 12. When unlocking is performed without the unlocking wrench 12, the elastic latch 4-1 is fixed in the anti-retraction groove 11-33-1 to achieve an anti-retraction effect, and the cable is crimped and installed at the jack 7; at this time, the insulating shell 3 is completely fixed and can neither rotate nor move axially, and it also has an anti-retraction function and a good sealing effect. The pin 10 is crimped to the cable, and passes through the anti-retraction locking nut 11, the sealing sleeve 9, and the anti-retraction gasket 4 in sequence and is installed in place. The anti-retraction gasket 4 passes through the tail of the pin insulating shell 3, and the second limit surface 4-2 and the stepped limit surface 1-3 fit together to limit the axial rotation of the anti-retraction gasket 4; the sealing sleeve 9 is installed, the anti-rotation tooth 1-2 falls into the anti-rotation groove 9-1, and the sixth plane 9-2 is inserted into the inner wall of the insulating shell 3. At this time, the sealing sleeve 9 and the insulating shell 3 cannot rotate relative to each other; the anti-retraction locking nut 11 is installed and tightened, and the inner surface of the anti-retraction locking nut 11 fits with the outer surface of the sealing sleeve 9. As the anti-retraction locking nut 11 rotates, the inner diameter of the sealing sleeve 9 shrinks and locks the cable, and the elastic tooth falls into the anti-retraction groove 11-3, continues to rotate and gradually locks, which plays the role of sealing, anti-retraction and keeping the pin stable; at the same time, the elastic tooth can be retracted by the unlocking wrench 12 to unlock. The pin insulating housing 3 is locked with the insulating housing 3 by snap-fitting, and a locking wire sealing ring 8 is provided on the insulating housing 3 to achieve a sealing protection effect.
[0043] In addition to the above-mentioned operating steps, in order to achieve a better sealing effect, a sealing gasket 5 can be added between the installation panel 6 and the anti-retraction gasket 4 to achieve a double-layer sealing effect with stronger protective performance.
[0044] In this embodiment, the tail structures of the insulating housings 3 of the male connector 1 and the female connector 2 are the same and can be installed interchangeably as required, and both can meet the requirements of anti-retraction and sealing.
[0045] In some embodiments, in order to achieve a better anti-retraction effect, the anti-retraction gasket 4 may be further provided with two or more elastic locking teeth 4 - 1 to improve the anti-retraction effect.
[0046] In this embodiment, the anti-retraction gasket 4 and the insulating shell 3 are designed to be separated. In some scenarios where the anti-retraction function is not required, the anti-retraction gasket 4 can be removed to obtain a connector without the anti-retraction function, thereby improving the convenience of disassembly and installation of the connector and expanding the application scenarios and scope of the product.
