Description

Technical Field

[0001] This invention relates to a waterproof connector, and more particularly to a push-type waterproof connector that can prevent accidental contact and water leakage. 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, a first water pipe connector 83, and a press-fit fastener 84. The first water valve assembly 82 is housed within the first tube body 81 and moves axially. The press-fit fastener 84 extends radially through the first tube body 81 and is located near the front opening 811 of the first tube body 81. The press-fit fastener 84 moves radially relative to the first tube body 81. The rear opening 812 of the first tube body 81 communicates with the first water pipe connector 83 and is connected to a water pipe 85 via the first water pipe connector 83.

[0003] The aforementioned male-end waterproof connector 90 includes a second tube body 91, a second water valve assembly 92, and a second water pipe connector 93. The second water valve assembly 92 is housed within the second tube body 91 and moves axially. The rear port 912 of the second tube body 91 communicates with the second water pipe connector 93 and is connected to another water pipe 94 through the second water pipe connector 93.

[0004] When the male waterproof connector 90 is to be inserted into the female waterproof connector 80, first press the snap-fit ​​84 and move it radially toward the first tube body 81 until the insertion portion 911 of the second tube body 91 of the male waterproof connector 90 is fully inserted into the first tube body 81 from the front opening 811. Figure 7B As shown, the pressing latch 84 is released, causing the pressing latch 84 to engage with the second pipe body 91 within the first pipe body 81. During insertion, the second water valve assembly 92 contacts the first water valve assembly 82 and axially pushes the first water valve assembly 82 away from the front port 811 of the first pipe body 81, thereby connecting the second pipe body 91 with the first pipe body 81 to form a smooth water passage.

[0005] When the male waterproof connector 90 is to be detached from the female waterproof connector 80, the water supply to the two water pipes 85 and 94 should be turned off first. Then, the pressing latch 84 should be operated in the reverse order of the above operation. This will allow the male waterproof connector 90 to be successfully detached from the female waterproof connector 80 without leakage. However, since the pressing latch 84 is located on the outside of the first tube 81 of the female waterproof connector 80, accidental collisions often cause the pressing latch 84 to fail to momentarily lock the second tube 91 of the male waterproof connector 90, resulting in the male waterproof connector 90 detaching from the female waterproof connector 80 and causing leakage. Therefore, further improvement is necessary. Summary of the Invention

[0006] In view of the fact that existing waterproof connector assemblies using press-fit fasteners are prone to water leakage due to impact, the main purpose of this invention is to provide a push-type waterproof connector assembly and its female waterproof connector that can prevent contact.

[0007] The main technical means to achieve the above objective is to include a female waterproof connector and a male waterproof connector that can be selectively inserted into the female waterproof connector. A pressing portion of a pressing latch of the female waterproof connector is spaced apart on the outside of a first tube of the female waterproof connector, allowing radial movement of the pressing latch to engage or disengage a second tube of the male waterproof connector located within the female waterproof connector.

[0008] A pressure-resistant component is provided on the outer side of the first tube of the female waterproof connector, the pressure-resistant component comprising:

[0009] A pushing part, axially movable, is disposed on the outer side of the first tube body, and does not radially overlap with the pressing buckle; and

[0010] A blocking portion extends integrally forward from a front end of the pushing portion and moves between a first position and a second position on the outer side of the first tube body due to the axial movement of the pushing portion; wherein:

[0011] When the blocking part moves to a first position outside the first tube body, the pressing part of the pressing buckle moves radially a first distance relative to the outer side of the first tube body; and

[0012] When the blocking part moves to the second position outside the first tube body, the pressing part of the pressing buckle moves radially a second distance relative to the outside of the first tube body; wherein the second distance is shorter than the first distance.

[0013] As described above, the waterproof connector assembly of the present invention mainly provides an axially movable anti-pressure member on the outside of the first tube of the female waterproof connector. The user pushes the pushing part of the anti-pressure member axially with his / her finger so that its blocking part moves to the first position and the second position on the outside of the first tube, thereby adjusting the radial movement distance of the pressing part of the pressing buckle relative to the outside of the first tube. That is, after the waterproof connector assembly is plugged in, the blocking part of the anti-pressure member is moved axially to the second position, limiting the radial movement distance of the pressing buckle to be insufficient to disengage the male waterproof connector from the pressing buckle.

[0014] The main technical means to achieve the above objective is to make the waterproof connector for the female connector include:

[0015] A first pipe body having a first front pipe opening and a first rear pipe opening;

[0016] A press-fit fastener includes a press portion and a latching portion; wherein the press portion is spaced apart on the outside of a first tube body of the female waterproof connector, and the latching portion extends integrally from the press portion and radially penetrates the first tube body, and is close to the first front opening of the first tube body.

[0017] A pressure-resistant component, disposed on the outside of the first pipe body, comprises:

[0018] A pushing part, axially movable, is disposed on the outer side of the first tube body, and does not radially overlap with the pressing buckle; and

[0019] A blocking portion extends integrally forward from a front end of the pushing portion and moves between a first position and a second position on the outer side of the first tube body due to the axial movement of the pushing portion; wherein:

[0020] When the blocking part moves to a first position outside the first tube body, the pressing part of the pressing buckle moves radially a first distance relative to the outer side of the first tube body; and

[0021] When the blocking part moves to the second position outside the first tube body, the pressing part of the pressing buckle moves radially a second distance relative to the outside of the first tube body; wherein the second distance is shorter than the first distance.

[0022] As can be seen from the above description, the outer side of the first tube of the female waterproof connector of the present invention is provided with an axially movable anti-pressure member. The user pushes the pushing part of the anti-pressure member axially with his / her finger so that its blocking part moves to the first position and the second position on the outer side of the first tube, thereby adjusting the radial movement distance of the pressing part of the pressing buckle relative to the outer side of the first tube. That is, when the waterproof connector assembly is plugged in, the blocking part of the anti-pressure member is moved axially to the second position, limiting the radial movement distance of the pressing buckle to be insufficient to make the male waterproof connector disengage from the pressing buckle.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Attached Figure Description

[0070] This invention relates to a push-type 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 technical content of this invention is described in detail below with reference to several embodiments and accompanying drawings.

[0071] Please refer to the following first. Figure 1 As shown, the push-type waterproof connector assembly 1 of the present invention includes a female waterproof connector 10 and a male waterproof connector 50 that can be selectively inserted into the female waterproof connector 10.

[0072] Please refer to the following: Figure 2 As shown, the aforementioned waterproof female connector 10 includes a first tube body 11, a pressure-resistant member 20, a pressing buckle member 30, a first water pipe connector 25, and a first water valve assembly 40; wherein the pressing buckle member 30 is disposed on the outer side 111 of the first tube body 11 and radially penetrates the first tube body 11, the first water pipe connector 25 is sleeved on the first tube body 11, and the first water valve assembly 40 is accommodated in the first tube body 11.

[0073] The aforementioned 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 50 to be inserted into, while the first rear port 13 communicates with the first water pipe connector 25. For example... Figure 3 As shown, the inner annular wall of the first tube 11 has an inner diameter R.T1 A constricted neck 14 protrudes inward near the first front opening 12, and the constricted neck 14 has a second inner diameter R. N The device comprises two opposing convex surfaces and a flat surface. The convex surface facing the first front opening 12 forms an inclined surface 141, while the other convex surface facing the first rear opening 13 is a vertical surface 142. A first sealing element 143 is embedded within the flat surface of the constricted neck 14. For example... Figure 3 As shown, the inner diameter R of the inner ring wall of the first tube 11 T1 The inner diameter R of the neck 14 is greater than N However, it is smaller than the diameter R of the first front port 12. F1 (R F1 >R T1 >R N In one embodiment, the outer side 111 of the first tube 11 forms a receiving groove 112 and a positioning groove 113, the positioning groove 113 being recessed into the bottom 114 of the receiving groove 112.

[0074] Please refer to the following: Figure 2 and Figure 3 As shown, the aforementioned anti-pressure member 20 includes a pushing portion 21 and a blocking portion 22. The pushing portion 21 is axially movable and disposed on the outer side 111 of the first tube body 11. The blocking portion 22 extends forward integrally from a front end of the pushing portion 21 and moves between a first position and a second position on the outer side 111 of the first tube body 11 due to the axial movement of the pushing portion 21. In this embodiment, the first position is closer to the first front opening 12 than the second position. The blocking portion 22 includes a plate 220 and at least one protrusion 221 integrally formed on the plate 220. The plate 220 abuts against the outer side 111 of the first tube body 11 and is thinner than the pushing portion 22. In one embodiment, the pushing portion 21 is slidably disposed within the receiving groove 112 and forms a slider 211 facing the receiving groove 112 to flatly adhere to the bottom 114 of the receiving groove 112. In this embodiment, a through groove 222 is formed at the front end of the plate 220, and two protrusions 221 are formed on the plate on two opposite sides near the through groove 222.

[0075] Furthermore, the anti-pressure component 20 further includes a second elastic element 23, a third elastic element 24, and a positioning ball 26. The second elastic element 23 is axially disposed between the pushing part 21 and the receiving groove 112, with one end abutting against the leading edge 253 of the first water pipe connector 25 and the other end abutting against the slider 211; the third elastic element 24 is radially fitted into the slider 211, and the positioning ball 26 is located in the positioning groove 113 and is pressed by the third elastic element 24.

[0076] Please refer to the following: Figures 1 to 3As shown, the aforementioned pressing and locking member 30 includes a pressing part 31, a locking part 32, and a first elastic member 33. The pressing part 31 is spaced apart on the outer side 111 of the first tube body 11 of the female waterproof connector 10, so that the pressing and locking member 30 can be moved radially to engage or disengage a portion of the male waterproof connector 50 located within the female waterproof connector 10. The pressing part 31 does not overlap radially with the pushing part 21 of the anti-pressure member 20, but overlaps radially with the plate 220 of the pushing part 21 of the anti-pressure member 20. The plate 220 is spaced apart from the inner surface 301 of the pressing part 31. The locking part 32 extends integrally from the pressing part 31, penetrates radially through the first tube body 11, is close to the first front tube opening 12, and is located before the neck 14. The first elastic member 33 is disposed between the inner surface 301 of the pressing part 31 and the outer surface 111 of the first tube body 11, providing a restoring force to the pressing part 31 after it is released from pressure. In the first embodiment, the pressing part 31 has a thickness and overlaps with the blocking part 22 of the anti-pressure member 20 in the radial direction. Its inner surface 301 forms a groove 311 corresponding to each protrusion 221 of the blocking part 22. The thickness is greater than the depth of the groove 311. The first elastic member 33 is closer to the first front tube opening 12 than in the first position, and the first elastic member 33 corresponds to the through groove 222 of the plate body 220 of the blocking part 22. Therefore, the first elastic member 33 can pass through the through groove 222 without interfering with the blocking part 22. Figure 3 As shown, when the pressing part 31 is released, the lower part 321 of the latching part 32 moves upward and protrudes into the first tube body 11.

[0077] like Figure 3 , Figure 4A Figure 4B As shown, to insert the male waterproof connector 50, the user first touches and pushes forward the pushing part 21, which is not radially overlapping with the pressing part 31, with their finger. The blocking part 22 moves to the first position. At this time, the positioning ball 26 moves axially from the positioning groove 113 forward to the bottom 114 of the receiving groove 112. The blocking part 22 is located between the pressing part 31 and the outer side 111 of the first tube body 11, and its two protrusions 221 are respectively aligned with the two grooves 311. Then, the pressing part 31 is pressed down. At this time, the two protrusions 221 of the blocking part 22 will enter the two grooves 311 of the pressing part 31, making the pressing part 31 closer to the outer side 111 of the first tube body 11. This allows the lower part 321 of the latching part 32 to move down and no longer protrude into the first tube body 11, without interfering with the insertion of the male waterproof connector 50, so that the male waterproof connector 50 can be inserted smoothly. For example... Figure 4BAs shown, after the male waterproof connector 50 is successfully inserted, the pressing part 31 is released. The restoring force of the compressed first elastic member 33 causes the pressing part 31 to move radially upward and return to its original position. Then, as... Figure 4C As shown, to ensure that the pressing part 31 is not impacted and the male waterproof connector 50 is disengaged, the pushing part 21 of the anti-pressure member 20 is moved axially backward, so that the blocking part 22 moves to the second position. At this time, the third elastic member 24 and the positioning ball 26 retract into the positioning groove 113, and the protrusions 221 on the blocking part 22 are no longer aligned with the corresponding groove 311, but abut against the inner surface 301 of the pressing part 31. Thus, when the pressing part 31 is impacted, it will be blocked by the two protrusions 221 and cannot be pressed down. Therefore, when the blocking portion 22 of the anti-pressure member 20 moves to the first position on the outer side 111 of the first tube body 11, the pressing portion 31 of the pressing buckle 30 moves radially a first distance relative to the outer side 111 of the first tube body 11; when the blocking portion 22 of the anti-pressure member 20 moves to the second position on the outer side 111 of the first tube body 11, the pressing portion 31 of the pressing buckle 30 moves radially a second distance relative to the outer side 111 of the first tube body 11; wherein the second distance is shorter than the first distance; in the first embodiment, Figure 4C The blocking portion 22 of the pressing portion 31, located in the second position, moves radially by a second distance relative to the outer side 111 of the first tube body 11, which is 0, and is shorter than... Figure 4A As shown, the blocking portion 22 of the anti-pressure member 20, located in the first position, moves radially a first distance relative to the outer side 111 of the first tube body 11.

[0078] Please see Figure 5A and Figure 5B As shown, this is a second embodiment of the axial push-type waterproof connector assembly 1a of the present invention. Its structure is mostly the same as the first embodiment, except that the blocking portion 22 of the anti-pressure member 20a extends integrally axially from the pushing portion 21 toward a first front opening 12 of the first tube body 11, and is L-shaped, including a straight plate 223 and a horizontal plate 224. The horizontal plate 224 is higher than the pressing portion 31 and is located outside the pressing portion 31. The straight plate 223 integrally connects the horizontal plate 224 and the pushing portion 21. Furthermore, the first and second positions in this embodiment are opposite to the first and second positions in the first embodiment. Figure 5A As shown, when the blocking part 22 moves axially rearward to the first position, the horizontal plate 224 does not radially overlap the outer side of the pressing part 31; as Figure 5BAs shown, when the blocking part 22 moves axially forward to the second position, the horizontal plate 224 of the blocking part 22 radially overlaps the outer side of the pressing part 31. Therefore, when the pressing part 31 is accidentally bumped, the pressing part 31 is blocked by the horizontal plate 224 of the blocking part 22 and cannot be pressed down. Therefore, in this embodiment, when the anti-pressure member 20a moves to the second position of the outer side 111 of the first tube 11, the pressing part 31 moves radially relative to the outer side 111 of the first tube 11 by a second distance of 0, which is shorter than the first distance that the anti-pressure member 20a can move when it moves to the first position of the outer side 111 of the first tube 11.

[0079] Please see Figure 6A and Figure 6B As shown, this is a third embodiment of the axial push-type waterproof connector assembly 1b of the present invention. Its structure is mostly the same as the second embodiment, except that the blocking portion 22 of the anti-pressure member 20b in this embodiment extends axially from the pushing portion 21 toward a first front opening 12 of the first tube body 11, forming a straight line; in one example, the blocking portion 22 and the pushing portion 21 have the same thickness. For example... Figure 6A As shown, when the blocking part 22 moves axially rearward to the first position, the blocking part 22 is not located at the position where the latching part 32 protrudes from the first tube body 11; as Figure 6B As shown, when the blocking part 22 moves axially forward to the second position, the blocking part 22 is positioned at the point where the lower part 321 of the latching part 32 protrudes from the outer side 111 of the first tube body 11. When the pressing part 31 is impacted and pressed down, the blocking part 32 limits the downward protrusion distance of the latching part 32, preventing the male waterproof connector 50 from disengaging. Therefore, in this embodiment, when the anti-pressure member 20b moves to the second position on the outer side 111 of the first tube body 11, the pressing part 31 moves radially relative to the outer side 111 of the first tube body 11 by a second distance of 0, which is shorter than the first distance that the anti-pressure member 20b can move when it moves to the first position on the outer side 111 of the first tube body 11. Similarly, as Figure 6C and Figure 6D As shown, in another embodiment, the anti-pressure member 20 is positioned on the outer side 111 of the same side as the pressing part 31; thus, when the blocking part 22 moves axially backward to the first position, neither the blocking part 22 nor the pushing part 21 radially overlaps with the pressing part 31, and the blocking part 22 is not located between the pressing part 31 and the outer side 111 of the first tube body 11; at this time, the pressing part 31 can be pressed, causing the lower part 321 of the latching part 32 to protrude from the outer side 111 of the first tube body 11. Figure 6BAs shown, when the blocking part 22 moves axially forward to the second position, the blocking part 22 is positioned between the pressing part 31 and the outer side 111 of the first tube body 11, radially overlapping with the pressing part 31 to prevent the pressing part 31 from pressing down. Therefore, in this embodiment, when the anti-pressure member 20b moves to the second position of the outer side 111 of the first tube body 11, the pressing part 31 moves radially relative to the outer side 111 of the first tube body 11 by a second distance of 0, which is shorter than the first distance that the anti-pressure member 20b can move when it moves to the first position of the outer side 111 of the first tube body 11.

[0080] For example Figure 2 and Figure 3 As shown, the first water pipe connector 25 is sleeved on the outer side 111 of the first pipe body 11 and connects to the first rear opening 13 of the first pipe body 11. It also forms a first recessed portion 251 corresponding to the first rear opening 13 of the first pipe body 11. The first recessed portion 251 has a first vertical inner wall surface 252 and a first inner diameter R. r1 The first inner diameter R r1 Smaller than the diameter R of the first rear nozzle 13 B1 .

[0081] The aforementioned first water valve assembly 40 includes a fixed valve member 41, a first movable valve member 42, and a first spring 43. One front end 411 of the movable valve member 42 is substantially flush with the vertical surface 142 of the constricted neck 14, while its rear end 412 abuts against the first vertical inner wall surface 252 of the first recessed portion 251 of the first water pipe connector 25. The first movable valve member 42 is slidably fitted over the front end 411 of the fixed valve member 41 and is shorter than the fixed valve member 41. The first movable valve member 42 abuts against the vertical surface 142 of the constricted neck 14, and a second sealing member 421 is fitted over the outer side 111 of the first movable valve member 42, contacting the inner annular wall of the first pipe body 11. The first spring 43 is fitted over the fixed valve member 41, with its two ends abutting against the rear ends 412 of the first movable valve member 42 and the fixed valve member 41, respectively.

[0082] The aforementioned male-end waterproof connector 50 includes a second tube body 51, a second water pipe connector 60, and a second water valve assembly 70. The second tube body 51 includes a front insertion portion 52 and a rear connection portion 53. The outer diameter of the front insertion portion 52 of the second tube body 51 matches the inner diameter R of the neck 14 of the first tube body 11. N A barb 521 is formed on the inclined surface 141 of the constricted neck 14 of the first tube body 11 on the outer side 111. The front insertion part 52 has a second front tube opening 522. The rear connecting part 53 is integrally connected to the front insertion part 52 and has a second rear tube opening 531.

[0083] The aforementioned second water pipe connector 60 is sleeved on the outer side 111 of the rear connection portion 53 of the second pipe body 51, and forms a second recessed portion 61 corresponding to the second rear pipe opening 531 of the second pipe body 51. The second recessed portion 61 has a second upright inner wall surface 611 and a second inner diameter R. r2 The inner diameter R of the second tube 51 T2 The diameter R of the second rear port 531 is the same. B2 And larger than the diameter R of the second front port 522. F2 The diameter R of the second front port 522 F2 The second inner diameter R is greater than that of the second inward portion 61. r2 (R T2 >R F2 >R r2 In one embodiment, the diameter R of the second front port 522 is... F2 Reduce the second inner diameter R of the second recessed portion 61 r2 Less than 0.7mm.

[0084] The aforementioned second water valve assembly 70 includes a second movable valve member 71 and a second spring 72. One front end of the second movable valve member 71 is substantially flush with the second front pipe opening 522, and a third sealing member 711 is fitted on its outer side 111. One end 721 of the second spring 72 abuts against a rear end of the second movable valve member 71, and the other end 722 abuts against the second vertical inner wall surface 611 of the second recessed portion 61 of the second water pipe connector 60.

[0085] Please see Figure 3 and Figure 4AAs shown, the male waterproof connector 50 is inserted into the first front port 12 of the female waterproof connector 10 through its front insertion portion 52. The front insertion portion 52 smoothly passes through the neck 14 and first contacts the first movable valve member 42 of the first water valve assembly 40, then moves it backward and compresses the first spring 43 until the barb 521 of the front insertion portion 52 abuts against the inclined surface 141 of the neck 14. The front end 411 of the fixing valve member 41 enters the second front port 522 of the front insertion portion 52, pushes the second movable valve member 71 of the second water valve assembly 70 backward, and compresses its second spring 72. At this time, the lower part 321 of the snap fastener 32 of the pressing snap fastener 30 and the barb 521 will engage with each other, locking the front insertion portion 52 of the male waterproof connector 50 inside the first tube body 11 of the female waterproof connector 10. During insertion, the second seal 421 of the first movable valve 42 moves backward and comes into close contact with the inner ring wall of the first tube 11, achieving a waterproof seal. Conversely, to remove the front insertion part 52 of the male waterproof connector 50 from the first front tube opening 12 of the female waterproof connector 10, press the pressing part 31 to release the engagement of the lower part 321 of the latching part 32 with the barb 521, and it can be smoothly pulled out backward (away from the first front tube opening 12). At this time, the originally compressed first spring 43 and second spring 72 respectively provide restoring force to their corresponding first movable valve 42 and second movable valve 71, pushing the first movable valve 42 and second movable valve 71 to such a position. Figure 3 The position shown is before it is plugged in.

[0086] In summary, the axial push-type waterproof connector assembly of the present invention mainly provides an axially movable anti-pressure member on the outside of the first tube body 11 of the female waterproof connector. When the anti-pressure member moves to the first position and the second position on the outside of the first tube body respectively, the radial movement distance of the pressing part of the pressing buckle relative to the outside of the first tube body can be adjusted to be long or short. That is, after the axial push-type waterproof connector assembly is inserted, the anti-pressure member is axially moved to the second position, and the radial movement distance of the pressing buckle is limited to be insufficient to make the male waterproof connector disengage from the pressing buckle.
