Description

Technical Field

[0001] This utility model relates to a waterproof connector, and more particularly to a waterproof female connector for waterway connections. Background Technology

[0002] Please see Figure 7A As shown, a conventional waterproof connector assembly includes a female waterproof connector 80 and a male waterproof connector 90. The female waterproof connector 80 includes a first tube body 81, a first water valve assembly 82, and a first water pipe connector 83. The first water valve assembly 82 is housed within the first tube body 81 and moves axially. The diameter of the front port 811 of the first tube body 81 is larger than the diameter of the rear port 812. The rear port 812 communicates with the first water pipe connector 83 and is connected to a water pipe (not shown) via the first water pipe connector 83. To enhance waterproofing, a waterproof gasket 84 is provided around the wall of the recessed portion 810 of the first tube body 81 near the front port 811. Figure 7B As shown, the waterproof gasket 84 protrudes from the tube wall of the recessed portion 810.

[0003] The aforementioned male waterproof connector 90 includes a second tube body 91 and a second water valve assembly 92. The second water valve assembly 92 is housed within the second tube body 91 and moves axially. The outer diameter of the front outer port 911 of the second tube body 91 is smaller than the front port 811 of the female waterproof connector 80, but matches the diameter of the inner recess 810. The rear port 912 of the second tube body 91 is used for connecting another water pipe (not shown in the figure).

[0004] In use, the male waterproof connector 90 is inserted into the female waterproof connector 80. The front end of its second tube 91 first passes through the front opening 811 of the female waterproof connector 80, and then through the waterproof gasket 84. Since the diameter of the outer opening of the second tube 91 matches the diameter of the inner recess 810, the waterproof gasket 84 is tightly pressed against the outer wall of the passing second tube 91 to ensure waterproof function. However, if... Figure 6A As shown, since the front outer diameter of the second tube 91 is smaller than the front opening 811 of the female waterproof connector 80, the user can easily insert the male waterproof connector 90 into the female waterproof connector 80 at an angle. This causes the front end of the second tube 91 to repeatedly squeeze the exposed part of the waterproof gasket 84, resulting in the waterproof gasket 84 being broken and damaged, leading to water leakage. Consequently, electronic or computer equipment using this waterproof connector assembly may be damaged by moisture. Therefore, further improvements are necessary. Utility Model Content

[0005] In view of the fact that the waterproof gasket of the female waterproof connector of the existing waterproof connector assembly is damaged by long-term insertion and removal, resulting in a decrease in waterproof function, the main utility model objective of this utility model is to provide a new waterproof connector assembly and its female waterproof connector.

[0117] This utility model relates to a waterproof connector assembly for connecting water supply pipes, which can be used, for example, for connecting liquid cooling pipes in liquid-cooled radiators, but is not limited to this application. The following detailed description of this utility model is provided with reference to several embodiments and accompanying drawings.

[0118] Please refer to the following first. Figure 1 and Figure 2 As shown, the waterproof female connector 10 of this utility model includes a first tube body 11, a first water valve assembly 20, and a first waterproof gasket 30. Furthermore, the waterproof female connector 10 may also further include a water pipe connector 40, a pressing latch 50, and a pressure-resistant component 60, wherein the water pipe connector 40 is sleeved on the first tube body 11, and the pressing latch 50 is disposed on the outer annular wall 112 of the first tube body 11 and radially penetrates the first tube body 11, as shown. Figure 6A As shown, the press-fit latch 50 is used to latch a mating male waterproof connector 70.

[0119] The first pipe body 11 has a first front port 12 and a first rear port 13. The first front port 12 is for the male waterproof connector to be inserted into, while the first rear port 13 communicates with the water pipe fitting 40. For example... Figure 3A As shown, the inner ring wall 111 of the first tube 11 has an inner diameter RT1, and a recessed portion 14 protrudes inward near the first front opening 12. The recessed portion 14 has a second inner diameter RN, and the inner diameter RT1 of the inner ring wall of the first tube 11 is greater than the inner diameter RN of the recessed portion 14, but smaller than the opening diameter RF1 of the first front opening 12 (RF1>RT1>RN).

[0120] The aforementioned first water valve assembly 20 is housed within the first pipe body 11 and positioned between the recessed portion 14 and the first rear pipe opening 13. In this embodiment, the first water valve assembly 20 includes a fixed valve member 21, a first movable valve member 22, and a first spring 23. A front end 211 of the fixed valve member 21 faces the first front pipe opening 12, while its rear end 212 abuts against the water pipe connector 40. The first movable valve member 22 is shorter than the fixed valve member 21, and the outer diameter of the outer ring wall 221 of the first movable valve member 22 is smaller than the inner diameter RT1 of the inner ring wall 111 of the first pipe body 11. Therefore, it can be sleeved with the first spring 23 on the fixed valve member 21. Thus, the first movable valve member 22 can slide between the recessed portion 14 and the first rear pipe opening 13. Furthermore, the outer diameter of the outer ring wall 221 of the first movable valve member 22 is smaller than the inner diameter RN of the recessed portion 14, so it can abut forward against the recessed portion 14. In addition, such as Figure 3B As shown, the outer ring wall 221 of the first movable valve 22 and the inner ring wall 111 of the first pipe body 11 maintain a first ring gap RGAP; in one embodiment, the first ring gap RGAP is between 0.05 and 0.25 mm.

[0121] Please refer to the following: Figure 3A and Figure 3B As shown, the first waterproof gasket 30 is located in the first annular gap RGAP between the first movable valve 22 and the inner annular wall 111 of the first tube body 11, that is, the first waterproof gasket 30 is located after the recessed portion 14. In this embodiment, the first waterproof gasket 30 is partially embedded in the inner annular wall 111 of the first tube body 11, and the remaining portion is exposed in the first annular gap RGAP, so the first waterproof gasket 30 is fixed on the inner annular wall 111 of the first tube body 11.

[0122] Please see again Figure 4A and Figure 4B As shown, in the second embodiment of the waterproof female connector 10a of this utility model, the first waterproof washer 30 is partially embedded in the outer ring wall 221 of the first movable valve member 22, and the remaining portion is exposed in the first ring gap RGAP. Thus, the first waterproof washer 30 can move with the movement of the first movable valve member 22. To further improve the waterproof performance of this embodiment, a second waterproof washer 31 can be added. The second waterproof washer 31 is partially embedded in the outer ring wall 221 of the first movable valve member 22, and is spaced apart from the first waterproof washer 30, with the remaining portion of the second waterproof washer 31 exposed in the first ring gap RGAP.

[0123] Please see again Figure 5A and Figure 5B As shown, this is the third embodiment of the waterproof female connector 10b of this utility model, which is related to... Figure 4AThe second embodiment shown is largely the same, but further includes a third waterproof washer 32. This third waterproof washer 32 is partially embedded in the inner annular surface 141 of the recessed portion 14, with the remaining portion protruding from the inner annular surface 141 of the recessed portion 14. The thickness d of the protruding portion is between 0.03 and 0.2 mm, and this thickness d is less than the first annular gap RGAP. In this embodiment, the protruding thickness d of the third waterproof washer 32 located in the recessed portion 14 is less than the first annular gap RGAP, reducing the impact area of ​​the protruding portion of the third waterproof washer 32 on the inclined insertion of the male waterproof connector. Combined with the first waterproof washer 30 being disposed in the recessed portion 14, the waterproof function of the female waterproof connector can still be maintained.

[0124] The aforementioned water pipe connector 40 includes a connecting pipe 41 and a threaded portion 42. The connecting pipe 41 is used for inserting and fixing a water supply pipe (not shown in the figure), and the threaded portion 42 extends outward and forward from one front end of the connecting pipe 41, and fits and threads onto the outer annular wall 112 of the first pipe body 11 near the first rear pipe opening 13. Therefore, the threaded portion 42 can provide the rear end of the fixing valve member 21 of the first water valve assembly 20 with abutment. In order to further enhance the waterproof performance of the female waterproof connectors 10, 10a, and 10b, two fourth waterproof washers 33 are respectively clamped at the front and rear of the threaded joint between the first pipe body 11 and the threaded portion 42.

[0125] The aforementioned pressing and latching component 50 includes a pressing part 51 and a latching part 52; wherein the pressing part 51 is spaced apart from the outer annular wall 112 of the first tube body 11, and the latching part 52 extends integrally from the pressing part 51 and radially penetrates the first tube body 11, and is close to the first front opening 12, such as... Figure 6A As shown, the snap-fit ​​part 52 is used to snap into the male waterproof connector 70.

[0126] The aforementioned anti-pressure member 60 is axially movable and disposed on the outer annular wall 112 of the first tube body 11, so as to selectively overlap radially with the pressing portion 51 of the pressing buckle member 50. When the anti-pressure member 60 does not overlap radially with the pressing portion 51 of the pressing buckle member 50, that is, it does not prevent the radial movement of the pressing buckle member 50, and the male waterproof connector 70 can be freely operated or not locked; conversely, when the anti-pressure member 60 moves axially to overlap radially with the pressing portion 51 of the pressing buckle member 50, it can prevent the radial movement of the pressing buckle member 50, that is, the pressing buckle member 50 is locked and cannot move radially.

[0127] Please see Figure 6AAs shown, the aforementioned male-end waterproof connector 70 includes a second tube body 71 and a second water valve assembly 77. The second tube body 71 includes a second front port 72 facing the first front port 12 and a second rear port 73, and the outer diameter of the second tube body 71 corresponding to the second front port 72 is slightly smaller than the inner diameter RN of the recessed portion 14 of the first tube body 11; in this embodiment, as... Figure 6C As shown, the second tube 71 maintains a second annular gap RGAP2 between the outer diameter of the second front opening 72 and the inner recess 14 of the first tube 11, i.e., a fit. Figure 5B As shown, the second ring gap RGAP2 is not greater than the protruding thickness d of the third waterproof gasket 32. In one embodiment, the second ring gap RGAP2 is smaller than the first ring gap RGAP. The diameter RB2 of the second rear port 73 through which liquid flows is smaller than the diameter RF2 of the second front port 72. In this embodiment, the outer ring wall 710 of the second tube body 71 further protrudes outward with a barb 711 and an outwardly protruding ring seat 712. The distance between the barb 711 and the outwardly protruding ring seat 712 matches the width of the snap-fit ​​portion 52 of the pressing snap fastener 50. Figure 6B As shown, when the second tube 71 is inserted into the first tube 11 and the barb 711 abuts against the recessed portion 14, the pressing portion 51 of the pressing buckle 50 is released, so that the buckle 52 passes upward through the first tube 11 and engages between the barb 711 and the outer protruding ring seat 712, thereby locking the male waterproof connector 70 in the female waterproof connector 10b.

[0128] The outer convex ring seat 712 of the second tube body 71 can be fitted with a first sealing ring 75. The second tube body 71 further forms an external thread 713 on the outer ring wall 710 corresponding to the second rear pipe opening 73. The external thread 713 and the outer convex ring seat 712 maintain a distance, so that a second sealing ring 76 can be fitted in it and is fitted on the outer ring wall 710 of the second tube body 71 side by side with the first sealing ring 75.

[0129] The aforementioned second water valve assembly 77 is disposed within the second pipe body 71 and includes a second movable valve member 771 and a second spring 772. The second movable valve member 771 faces the second front pipe opening 72, and the second spring 772 abuts against the second movable valve member 771 and the second rear pipe opening 73, respectively. The second movable valve member 771 is slidable between the second front pipe opening 72 and the second rear pipe opening 73. In one embodiment, the second pipe body 71 forms a concave ring 731 near the second rear pipe opening 73 for a washer 74 to be engaged and fixed therein.

[0130] Please see Figure 6A and Figure 6BAs shown, when the male waterproof connector 70 is inserted into the female waterproof connector 10b, the second front port 72 of its second tube 71 enters from the first front port 12 of the first tube 11. The second tube 71 passes through the inner recess 14 of the first tube 11, abuts against the first movable valve 22, and slides backward, compressing the first spring 23. The second movable valve 771 abuts against the front end 211 of the fixed valve 21 and moves relative to the second rear port 73, compressing the second spring 772. When the second tube 71 passes through the inner recess 14, as... Figure 6C As shown, the protruding portion of the third waterproof gasket 32 ​​is pressed against the outer annular wall 710 of the second tube 71 and the inner annular surface 141 of the recessed portion 14. That is, a portion of the third waterproof gasket 32 ​​is embedded into the inner annular surface of the recessed portion 14, and the remaining portion protrudes from the second annular gap RGAP2. This embodiment is the same as... Figure 5B As shown, the first waterproof gasket 30 is fitted onto the outer ring wall 221 of the first movable valve 22, thus pressing tightly between the inner ring wall 111 of the first tube body and the outer ring wall 221 of the first movable valve 22; in this way, a double waterproof structure is established between the first tube body 11 and the second tube body 71 to ensure that the waterproof connector assembly does not leak.

[0131] In summary, the waterproof connector of this utility model mainly places the waterproof gasket after the recessed portion; thus, even if the front end of a male waterproof connector is inserted at an angle from the front opening of the female waterproof connector, it cannot reach the waterproof gasket, and when the male waterproof connector passes through the recessed portion, it is no longer tilted; therefore, when the male waterproof connector is repeatedly inserted into the female waterproof connector, the waterproof gasket can be evenly squeezed and tightly fitted to the male waterproof connector, thereby extending its service life and maintaining the waterproof function of the female waterproof connector.

[0132] The above description is merely an embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above by way of embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
