DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] like Figure 1-4 As shown, the utility model discloses a waterproof and moisture-proof cable connector, comprising a male head 1, a female head 2 located on the right side of the male head 1, a shell A3 fixedly arranged on the outside of the male head 1, and a shell B4 fixedly arranged on the outside of the female head 2, wherein the male head 1 and the female head 2 are connected by a connecting component, wherein the connecting component comprises a thread A5 fixedly arranged on the outside of the shell A3, a convex ring A6 fixedly arranged on the left side of the thread A5, a screw sleeve A7 sleeved on the shell B4, a convex ring B8 fixedly arranged on the right side of the screw sleeve A7, a convex ring C9 fixedly arranged on the outside of the shell B4, a sealing gasket A10 fixedly arranged on the right side of the convex ring A6, and an anti-slip component arranged on the shell B4, wherein the convex ring B8 is connected to the anti-slip component, the diameter of the convex ring A6 is larger than the diameter of the thread A5, the inner diameter of the convex ring B8 is smaller than the diameter of the convex ring C9, and the convex ring B8 is located on the right side of the convex ring C9, and after the male head 1 is inserted into the female head 2, the screw sleeve A7 is threadedly connected with the thread A5, and the screw sleeve A7 is fixedly connected with the sealing gasket A10. When the utility model is used, the male head 1 is aligned and inserted into the female head 2, so that the friction sleeve A11 is inserted into the friction sleeve B12 and connected with it. The materials of the friction sleeve A11 and the friction sleeve B12 are elastic rubber. The friction sleeve A11 and the friction sleeve B12 fit together, which plays a role of pre-fixing the male head 1 and the female head 2; the screw sleeve A7 is screwed into the thread A5, so that the screw sleeve A7 is fixedly connected with the sealing gasket A10, which plays a sealing role. Since the inner diameter of the convex ring B8 is smaller than the diameter of the convex ring C9, the convex ring B8 is located on the right side of the convex ring C9, the screw sleeve A7 will drive the convex ring B8 to move, the convex ring B8 squeezes the convex ring C9, and the convex ring C9 drives the outer shell B4 to move, so that the outer shell B4 and the sealing gasket B 13 is fixedly connected, which plays a further sealing role; the screw sleeve B15 is screwed into the thread B14, so that the spring washer 16 is fixedly connected with the screw sleeve B15 and the convex ring B8, and the spring washer 16 applies an elastic force to the screw sleeve B15, so that the threads of the screw sleeve B15 and the thread B14 are pressed tightly, which plays a role in preventing the screw sleeve B15 from loosening, and then preventing the screw sleeve A7 from loosening, and playing a role in ensuring the sealing; in summary, the utility model has a strong sealing performance and has the beneficial effects of being waterproof and moisture-proof, and solves the problem that the existing cable connector has poor sealing performance and lacks waterproof and moisture-proof functions, which easily causes water vapor and small water droplets to penetrate into the cable connector, resulting in leakage or even short circuit.
[0020] Preferably, the connection assembly further comprises a friction sleeve A11 fixedly arranged on the housing A3, and a friction sleeve B12 fixedly arranged inside the housing B4, and after the male head 1 is inserted into the female head 2, the friction sleeve A11 is inserted into the friction sleeve B12 to be in contact with it. Since the friction sleeve A11 is inserted into the friction sleeve B12 to be in contact with it after the male head 1 is inserted into the female head 2, the materials of the friction sleeve A11 and the friction sleeve B12 are both elastic rubber, and the friction sleeve A11 and the friction sleeve B12 are attached to each other, which plays a role in pre-fixing the male head 1 and the female head 2; when the male head 1 is inserted into the female head 2, the friction sleeve A11 and the friction sleeve B12 rub against each other, which plays a role in preventing the outer sides of the male head 1 and the female head 2 from being worn.
[0021] Preferably, the connection assembly further comprises a sealing gasket B13 fixedly arranged on the housing A3, and the sealing gasket B13 is fixedly connected to the housing B4 after the threaded sleeve A7 is threadedly connected to the thread A5. Since the sealing gasket B13 is fixedly connected to the housing B4 after the threaded sleeve A7 is threadedly connected to the thread A5, a sealing effect is played to prevent external water vapor from entering the male head 1 or the female head 2.
[0022] Preferably, the anti-slip assembly includes a thread B14 and a screw sleeve B15 fixedly arranged on the outer side of the housing B4, the thread B14 is located on the right side of the convex ring C9, the thread B14 has a diameter smaller than the inner diameter of the convex ring B8, and the screw sleeve B15 is fixedly connected to the convex ring B8 after being threadedly connected to the thread B14. Since the thread B14 has a diameter smaller than the inner diameter of the convex ring B8, it is convenient to unscrew the screw sleeve A7; since the screw sleeve B15 is fixedly connected to the convex ring B8 after being threadedly connected to the thread B14, the screw sleeve B15 will press the convex ring B8 and the screw sleeve A7, thereby preventing the screw sleeve A7 from loosening.
[0023] Preferably, the anti-slip assembly further comprises an elastic washer 16 located between the screw sleeve B15 and the convex ring B8, and the screw sleeve B15 is threadedly connected to the thread B14 after the elastic washer 16 is fixedly connected to the screw sleeve B15 and the convex ring B8. Since the screw sleeve B15 is threadedly connected to the thread B14 after the elastic washer 16 is fixedly connected to the screw sleeve B15 and the convex ring B8, the elastic washer 16 applies an elastic force to the screw sleeve B15, so that the screw sleeve B15 and the thread B14 are pressed against each other, thereby preventing the screw sleeve B15 from loosening.
[0024] Preferably, the thread A5 is a forward thread, and the thread B14 is a reverse thread. Since the thread A5 is a forward thread and the thread B14 is a reverse thread, the screw sleeve A7 and the screw sleeve B15 are screwed out in opposite directions, which further prevents the screw sleeve A7 from loosening.
[0025] Preferably, a positioning strip 17 is fixedly provided on the male connector 1, a positioning groove 18 matching the positioning strip 17 is provided on the female connector 2, and the positioning strip 17 is inserted into the positioning groove 18 and is in contact with the female connector 2.
