For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0043] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a VDA connector with a drum clamp 200, including a female connector body 100 and a drum clamp 200; the female connector body 100 is provided with a mounting groove 110 for mounting the drum clamp 200, and the drum clamp 200 is snapped into the mounting groove 110; the drum clamp 200 has an arc-shaped locking section 210 in the middle that can be adapted to the male connector.
[0045] Specifically, a drum-shaped clamp 200 is provided on the female connector body 100. The drum-shaped clamp 200 has an arc-shaped locking section 210 in the middle that can be adapted to the male connector. When the male connector is connected to the female connector body 100, as the male connector is inserted into the female connector body 100, the arc-shaped locking section 210 is first pushed outward by the outer contour of the male connector. The arc-shaped locking section 210 reduces the resistance of the male connector to open the arc-shaped locking section 210 and reduces the insertion force of the male connector into the female connector body 100, making it easier for operators to operate. Moreover, after the arc-shaped locking section 210 falls into the groove on the male connector, it will retract inward to reset. The arc-shaped locking section 210 can better adapt to the outer contour of the male connector and maintain the locking force on the male connector.
[0046] It should be noted that by setting an arc-shaped locking section 210 on the drum clamp 200, the setting of the arc-shaped locking section 210 can reduce the opening force of the male connector to open the arc-shaped locking section 210, thereby making it easier for the staff to insert the male connector into the female connector body 100.
[0047] Meanwhile, by setting the arc-shaped locking section 210, the elastic deformation of the drum clamp 200 can be increased, avoiding plastic deformation of the clamp when the female connector body 100 and the male connector are connected, which would lead to a decrease in locking force.
[0048] See Figure 1 - Figure 7 As shown, in the optional scheme of this embodiment, the drum clamp 200 includes a locking section 220, a lifting unlocking section 230, and an arc-shaped locking section 210; there are two arc-shaped locking sections 210 and two locking sections 220; one end of each arc-shaped locking section 210 is connected to the locking section 220, and the other end is connected to the lifting unlocking section 230.
[0049] Among them, the drum-type clamp 200 is U-shaped.
[0050] The lifting unlocking section 230 and the locking section 220 are connected in an L-shape.
[0051] Among them, the arc-shaped locking section 210 can be adapted to the outer contour of the male connector.
[0052] See Figure 1 - Figure 7 As shown, in an optional embodiment, the female connector body 100 is provided with a locking groove 300 for fitting the locking section 220.
[0053] The locking groove 300 includes a locking limiting groove 310 and an unlocking limiting groove 320, and an outwardly expanding guide brace 330 is provided between the locking limiting groove 310 and the unlocking limiting groove 320; when the drum clamp 200 locks the male connector, the locking section 220 engages with the locking limiting groove 310, and when the drum clamp 200 disengages from the male connector, the locking section 220 engages with the unlocking limiting groove 320.
[0054] Specifically, the drum clamp 200 is inserted into the mounting groove 110. The middle part of the mounting groove 110 is a through structure. The arc-shaped locking section 210 of the drum clamp 200 can pass through the through structure in the middle of the mounting groove 110 and engage with the male connector inside the female connector body 100.
[0055] In addition, a locking groove 300 is provided on the outer wall of the female connector body 100. The locking groove 300 is connected to the mounting groove 110. The locking section 220 of the drum clamp 200 can be locked in the locking groove 300 to ensure the stability of the drum clamp 200.
[0056] It should be noted that when the male and female connector bodies 100 are disassembled, the worker lifts and pulls the unlocking section 230. Lifting the unlocking section 230 causes the arc-shaped locking section 210 to rise, thereby causing the locking section 220 to slide out of the locking limit groove 310. Then, the locking limit groove 310 moves along the outwardly expanding guide brace 330 into the unlocking limit groove 320. At this time, the arc-shaped locking section 210 disengages from the male connector's slot, and the male connector can be pulled out from the female connector body 100.
[0057] See Figure 1 - Figure 7As shown, in an optional embodiment, a sealing ring 410 and a retaining ring 420 are provided inside the female connector body 100; a sealing seat for installing the sealing ring 410 is provided inside the female connector body 100, and the retaining ring 420 is snapped into the female connector body 100 so that the retaining ring 420 constrains the sealing ring 410 on the sealing seat.
[0058] The female connector body 100 is provided with a connecting slot 120 and a guide slide 130; the retaining ring 420 is provided with a connecting block 421 and a guide slider 422, the connecting block 421 is engaged with the connecting slot 120, and the guide slider 422 is slidably disposed in the guide slide 130.
[0059] Specifically, the retaining ring 420 is snapped into the female connector body 100, and the retaining ring 420 can restrain the sealing ring 410, so that the sealing ring 410 can seal the male connector and the female connector body 100.
[0060] This embodiment provides an automotive cooling piping system, including a VDA connector with a drum clamp 200.
[0061] Specifically, the automotive cooling piping system provided in this embodiment has the advantages of the VDA connector with drum clamp 200 compared with the prior art, which will not be elaborated here.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
