[0036] Figure 1 Fig. 1 is a perspective view of a waterproof connector set according to an embodiment of the present application before assembly. Figure 2 Figure 1 Fig. 2 is a perspective view of the waterproof connector set of Fig. 1 after assembly. Figure 3 Figure 1 Fig. 3 is a cross-sectional view of the waterproof connector set of Fig. 2 after assembly. Figure 4 Figure 1 Fig. 4 is a cross-sectional view of a waterproof sleeve of Fig. 3.
[0037] Referring to Figures 1 to 4 The waterproof connector set 10 of the present embodiment includes a first connector 20, a second connector 30, and a waterproof sleeve 40. The second connector 30 is pluggably butted against the first connector 20. In the present embodiment, the first connector 20 and the second connector 30 are, for example, USB connectors, such as a USB TYPE A connector or a USB TYPE C connector. Of course, in other embodiments, the first connector 20 and the second connector 30 can be network connectors or other connectors, and the types of the first connector 20 and the second connector 30 are not limited thereto.
[0038] The waterproof sleeve 40 includes a sleeve body 42 and two flexible lugs 46. The sleeve body 42 includes two opposite openings 44. Since the two openings 44 of the sleeve body 42 are mutually through, at least a portion of each of the first connector 20 and the second connector 30 can extend into the sleeve body 42, so that the sleeve body 42 is sleeved on the mutually butted first connector 20 and second connector 30.
[0039] The two flexible lugs 46 are integrally formed on the sleeve body 42 near the two openings 44 and extend toward the centers of the openings 44. The two flexible lugs 46 respectively abut against the first connector 20 and the second connector 30, and seal the portions of the first connector 20 and the second connector 30 between the two flexible lugs 46.
[0040] In the present embodiment, the cross-sectional areas of the two openings 44 of the waterproof sleeve 40 are respectively smaller than the cross-sectional areas of the outermost contour of the first connector 20 and the second connector 30 at the positions corresponding to the two openings 44. Such a design can make the waterproof sleeve 40 need to be first expanded when being sleeved on the first connector 20 and the second connector 30, so that the first connector 20 and the second connector 30 can be accommodated in the sleeve body 42 after being inserted, and the two flexible lugs 46 can abut against the first connector 20 and the second connector 30 well, thereby achieving a sealing purpose.
[0041] Since the joint of the first connector 20 and the second connector 30 is located between the two flexible lugs 46, external liquid, such as rainwater or moisture, can be isolated outside the two flexible lugs 46.
[0042] Since the two butting surfaces of the first connector 20 and the second connector 30 are located in the sealed range, external liquid, such as rainwater or moisture, cannot penetrate into the interiors of the first connector 20 and the second connector 30 through the two butting surfaces of the first connector 20 and the second connector 30, and the butted two connectors can have good reliability and waterproof performance.
[0043] In the present embodiment, each flexible protruding ring 46 can optionally comprise a ring-shaped protrusion 48 extending from the inner surface of the sleeve body 42 towards the other opening 44 proximate to the two openings 44. The flexible protruding ring 46 is abutted against the first connector 20 and the second connector 30 by the ring-shaped protrusion 48 to achieve a sealing effect.
[0044] In addition, by Figure 3 It can be seen that in the present embodiment, the sleeve body 42 is tightly fitted to the covered first connector 20 and the second connector 30, and such a design can further improve the waterproof performance. Of course, in an embodiment, the sleeve body 42 can also have a gap with the covered first connector 20 and the second connector 30, as long as the two flexible protruding rings 46 are abutted against the first connector 20 and the second connector 30, respectively.
[0045] It is to be noted that in the present embodiment, the sleeve body 42 is flexible, and the sleeve body 42 and the two flexible protruding rings 46 are made of the same material, for example, silicone or rubber. Of course, the sleeve body 42 and the two flexible protruding rings 46 can also be made of other materials, as long as the hardness of the sleeve body 42 and the two flexible protruding rings 46 is between 30 and 60.
[0046] In other embodiments, the sleeve body 42 is flexible, and the sleeve body 42 and the two flexible protruding rings 46 can also be made of different materials. In another embodiment, the sleeve body 42 can also be hard, for example, made of plastic, but is not limited thereto. The two flexible protruding rings 46 made of rubber or silicone are integrally formed on the hard sleeve body 42.
[0047] Please refer to Figure 4 In the present embodiment, the thickness T of the sleeve body 42 is between 1 millimeter (mm) and 1.5 millimeters, and such a thickness T of the sleeve body 42 can prevent the first connector 20 and the second connector 30 from being damaged or bent by external force after being plugged in, so as to provide sufficient protection. In addition, the height H of the two flexible protruding rings 46 protruding from the inner surface of the sleeve body 42 is between 0.3 millimeters and 0.5 millimeters. The height H of the two flexible protruding rings 46 protruding from the inner surface of the sleeve body 42 in the above range can enable the two flexible protruding rings 46 to cover and abut against the first connector 20 and the second connector 30. Of course, the thickness T and the height H are not limited thereto.
[0048] As Figure 3 shown, the first connector 20 comprises a first bottom surface 22 away from the second connector 30, and the second connector 30 comprises a second bottom surface 32 away from the first connector 20. Two transmission lines extend from the first bottom surface 22 and the second bottom surface 32.
[0049] In the present embodiment, the sleeve body 42 covers the entire first connector 20 and the second connector 30, and the two flexible lugs 46 abut against the first bottom surface 22 and the second bottom surface 32, respectively. Since the first bottom surface 22 and the second bottom surface 32 are opposite to each other, such design can make the two flexible lugs 46 apply fastening force to the first bottom surface 22 and the second bottom surface 32 at the same time when covering the first connector 20 and the second connector 30, so that the waterproof sleeve 40 is interfered and is not easy to fall off from the first connector 20 and the second connector 30, and at the same time, the effect of not easy to be loosened after the first connector 20 and the second connector 30 are plugged in can be achieved synchronously.
[0050] Of course, in other embodiments, the two flexible lugs 46 can interfere / abut against the side surfaces of the first connector 20 and the second connector 30, and the covering range of the sleeve body 42 can be from the plugging-in position of the first connector 20 and the second connector 30 to the positions adjacent to the first bottom surface 22 and the second bottom surface 32 of the first connector 20 and the second connector 30. When the two flexible lugs 46 are arranged beside the plugging-in position, that is, the size of the sleeve body 42 is smaller, at least the plugging-in position can be protected, and preferably, the two flexible lugs 46 are buckled on the first bottom surface 22 and the second bottom surface 32 of the first connector 20 and the second connector 30, that is, the size of the sleeve body 42 is larger, the first connector 20 and the second connector 30 can be completely covered, so as to provide better waterproof and moisture-proof, connector stability and other effects.
[0051] In one embodiment, the two annular protrusions 48 of the waterproof sleeve 40 can also abut against the two side surfaces of the first connector 20 and the second connector 30, and the sealing effect can also be achieved. In another embodiment, the two flexible lugs 46 of the waterproof sleeve 40 can also not have the two annular protrusions 48, which is not limited by the drawings.
[0052] In one embodiment, when the waterproof sleeve 40 abuts against the first bottom surface 22 and the second bottom surface 32 of the first connector 20 and the second connector 30 (that is, the waterproof sleeve 40 covers the side surfaces of the first connector 20 and the second connector 30), the hardness of the waterproof sleeve 40 is preferably higher in the hardness range of 30 to 60, for example, between 45 and 60.
[0053] When the waterproof sleeve 40 abuts against the side surfaces of the first connector 20 and the second connector 30 (that is, the waterproof sleeve 40 partially covers the side surfaces of the first connector 20 and the second connector 30, and the remaining side surfaces can be exposed), the hardness of the waterproof sleeve 40 is preferably lower in the hardness range of 30 to 60, for example, between 30 and 45. Of course, the relationship between the hardness of the waterproof sleeve 40 and the position where the waterproof sleeve 40 abuts against the first connector 20 and the second connector 30 is not limited thereto.
[0054] Please return toFigure 1 When the waterproof sleeve 40 is to be fitted to the first connector 20 and the second connector 30, the waterproof sleeve 40 can be first fitted to one of the first connector 20 and the second connector 30, and then moved to the transmission line of the fitted first connector 20 or the second connector 30, and then the first connector 20 is connected to the second connector 30. Then, the waterproof sleeve 40 is moved towards the other of the first connector 20 or the second connector 30 until the waterproof sleeve 40 covers at least a portion of each of the first connector 20 and the second connector 30, as shown in Figure 2 , to complete the assembly.
[0055] The waterproof sleeve 40 of the present application has a simple structure, low cost, simple assembly and good waterproof effect. It has been found that the waterproof connector set 10 can achieve IP68 waterproof effect, and has good waterproof performance, thereby improving the reliability of the first connector 20 and the second connector 30.
[0056] In summary, the two flexible protrusions of the waterproof sleeve of the present application are integrally formed on the sleeve body near the two openings, the sleeve body is fitted to the first connector and the second connector which are engaged with each other, and the two flexible protrusions can abut against the outer contour of the connected first connector and second connector. Therefore, external liquids such as rainwater or moisture can be isolated from the two connecting surfaces of the first connector and the second connector, thereby preventing the liquids from penetrating into the interior of the first connector and the second connector. Therefore, the waterproof sleeve of the present application can improve the reliability and waterproof performance of the two connected connectors in a low-cost manner, and the waterproof connector set of the present application can have good reliability and waterproof performance.
