Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts connectors, specifically to a quick-connect connector. Background Technology

[0002] Quick-connect couplings, also known as fast-connect plugs, are the most convenient plug-and-play connection method, especially advantageous in situations where pipe connections are difficult, such as those with limited space or challenging pipe assembly. Quick-connect couplings are frequently used in automotive water cooling systems, intercooler piping, and energy storage systems to connect pipes. However, conventional pressure relief quick-connect couplings (VDA series) use O-ring seals, posing a risk of leakage, and their insertion and removal resistance is relatively high, potentially causing fatigue for maintenance personnel. Utility Model Content

[0003] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a quick-connect connector that is easy to assemble, labor-saving, and reliable, thus overcoming the difficulties of the prior art.

[0004] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0005] A quick-connect connector includes a male connector and a housing. The inner wall of the housing is provided with a sealing groove, in which a sealing ring and an internal clamp are fitted. At least two locking blocks are evenly distributed circumferentially on the side wall of the internal clamp. The housing is provided with locking holes for the locking blocks to engage. The outer side of the housing is provided with a locking slot, in which a positioning clip is fitted. The outer side wall of the male connector is provided with an annular groove. The end of the male connector extends into the housing. After the side wall of the male connector is pressed against the sealing ring and the internal clamp, the positioning clip falls into the annular groove to position the male connector.

[0006] Preferably, the sealing ring is corrugated, and the wall of the sealing groove that mates with the sealing ring is also corrugated.

[0007] Preferably, the wall where the inner clamp and the sealing ring mate is also corrugated, the inner wall of the tube without the clamp is a conical surface, and the male connector is provided with a conical part for contacting the conical surface.

[0008] Preferably, the clamping movable groove includes a clamping cavity with internal and external communication, a clamping groove outside the clamping cavity, and a slope connecting the clamping groove. The positioning clamp is a "U"-shaped rod structure with two bends, two clamping rods, and a carrying rod. The carrying rod connects to the two clamping rods, and the two bends are respectively located on the two corresponding clamping rods and cooperate with the clamping groove. When the carrying rod is pulled, the bends slide on the slope and open the two clamping rods.

[0009] Preferably, a straight groove is provided on the inner sidewall of the end of the housing, and a straight block is provided on the male connector to engage with the straight groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model configures a sealing ring and an internal clamp in the sealing groove, so that when the male connector is inserted, the front end of the male connector directly abuts against the internal clamp, and the internal clamp squeezes and deforms the sealing ring, thereby allowing the sealing ring to better perform its sealing effect. Then, in order to prevent the male connector from falling off or loosening, a positioning clamp is used to cooperate on the annular groove to achieve positioning and prevent detachment. The assembly method is simple and efficient, and the sealing effect is significantly improved.

[0012] 2. In this utility model, the sealing ring is designed as a wave shape, thereby increasing the contact area. Therefore, the inner tube clamp and the shell that come into contact with the sealing ring are designed to increase the contact area, which improves the sealing effect and extends the service life of the sealing ring.

[0013] 3. In this utility model, the male connector is provided with a tapered part, which can improve the guiding and concentric fit, automatically correct the concentric position of the fit, and then increase the contact area to improve the sealing effect;

[0014] 4. The movable slot of the clamp is designed with a slope, which makes it easier for the positioning clamp to be assembled into the movable slot. During the insertion action, the positioning clamp can automatically enter the ring groove for engagement. When disassembly is required, the positioning clamp can be opened by pulling the handle.

[0015] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0026] Example:

[0027] This invention discloses a quick-connect connector, as per an embodiment. Figure 1 , Figure 2 and Figure 3 As shown, the device includes a male connector 1 and a housing 2. A sealing groove 21 is provided on the inner wall of the housing 2, and a sealing ring 3 and an internal clamp 4 fit within the sealing groove 21. At least two locking blocks 41 are evenly distributed circumferentially on the side wall of the internal clamp 4. The housing 2 is provided with locking holes 22 for the locking blocks 41 to engage. The locking blocks 41 have a triangular block structure and can slide into the locking holes 22 in one direction.

[0028] The outer side of the housing 2 is provided with a clamping groove 23, and a positioning clamp 5 is installed in the clamping groove 23. An annular groove 11 is provided on the outer side wall of the male connector 1. The end of the male connector extends into the housing 2. After the side wall of the male connector is pressed against the sealing ring 3 and the internal clamp 4, the positioning clamp 5 falls into the annular groove 11 to position the male connector.

[0029] In this scheme, the working principle is as follows: A sealing ring 3 and an inner tube clamp 4 are configured in the sealing groove 21, so that when the male connector 1 is inserted, the front end of the male connector 1 directly abuts against the inner tube clamp 4, and the inner tube clamp 4 squeezes and deforms the sealing ring 3, so that the sealing ring 3 can better perform the sealing effect. Then, in order to keep the male connector from falling off and loosening, the positioning clamp 5 is used to cooperate on the annular groove 11 to achieve positioning and prevent detachment. The assembly method is simple and efficient, and the sealing effect is significantly improved.

[0030] To further improve the sealing effect, refer to Figure 1 and Figure 4 As can be seen, the sealing ring 3 is corrugated, and the wall of the sealing groove 21 that mates with the sealing ring 3 is also corrugated. The wall of the inner clamp 4 that mates with the sealing ring 3 is also corrugated. The inner wall of the pipe without the clamp is a conical surface 42. A conical part 12 is provided on the male connector 1, which is used to abut against the conical surface 42.

[0031] In this design, the sealing ring 3 is designed as a wave shape to increase the contact area. Therefore, the inner tube clamp 4 and the housing 2, which contact the sealing ring 3, also have an increased contact area design, improving the sealing effect and extending the service life of the sealing ring 3. The male connector is provided with a tapered portion 12, which improves guidance and concentricity, automatically corrects the concentric position of the fit, and further increases the contact area to enhance the sealing effect.

[0032] Further optimization of the above scheme is as follows: The clamping groove 23 includes a clamping cavity 231 with internal and external communication, a clamping groove 232 outside the clamping cavity 231, and a slope 233 connecting the clamping groove 232. The positioning clamp 5 is a "U"-shaped rod structure with two bends 51, two clamping rods 52, and a handle 53. The handle 53 connects to the two clamping rods 52, and the two bends 51 are respectively located on the two corresponding clamping rods 52 and cooperate with the clamping groove 232. When the handle 53 is pulled, the bends 51 slide on the slope 233 and open the two clamping rods 52.

[0033] The movable slot 23 of the clamp is designed with a slope 233, so that the positioning clamp 5 is easier to assemble into the movable slot 23 of the clamp. During the insertion action, the positioning clamp 5 can automatically enter the annular groove 11 for clamping. When it is necessary to disassemble, the positioning clamp 5 can be opened by pulling the handle 53.

[0034] To ensure more efficient assembly, easier alignment, and more stable insertion, a straight groove 24 is provided on the inner side wall of the end of the housing 2, and a straight block 13 is provided on the male connector 1 to engage with the straight groove 24.

[0035] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
