Description

Technical Field

[0001] The utility model relates to the technical field of dustproof and waterproof connectors, in particular to a sealing assembly and a connector. Background Art

[0002] The sealing of the plug-in interface of the connector product is usually achieved by using a sealing rubber ring. For example, a vehicle connector disclosed in the Chinese utility model patent with authorization announcement number CN208226172U includes a connector housing and a conductor installed in the connector housing. A sealing ring is installed on the outer side of the port of the connector housing for plugging with the adapter socket to achieve sealing of the plug-in position of the header. The sealing ring is installed in an annular groove on the outer side of the connector housing. During assembly, the sealing ring is installed in the annular groove by expanding the sealing ring. In this way, the sealing ring is expanded too much, which affects the size adaptability of the sealing ring and the bottom of the annular groove to a certain extent, and makes the sealing ring more easily deformed, thereby affecting its sealing performance. In view of the above problems, there is also a connector structure in the prior art, such as Figure 1-2 As shown, the sealing rubber ring 3 is sleeved on the outer surface of the plug-in port 10 of the connector housing 1, and the anti-slip ring 2 is installed at the plug-in port 10 of the connector housing 1 through the snap structure 21 to prevent the sealing rubber ring 3 from slipping out, and the anti-slip ring 2 cooperates with the retaining edge 11 at the plug-in port 10 to ensure the degree of deformation of the sealing rubber ring 3, so as to ensure the sealing performance of the sealing rubber ring 3. However, in the field of automotive connectors, the connector housing is mostly a plastic thin-walled part, and the anti-slip ring is installed at the plug-in port of the connector housing through the snap structure. The installation structure is often weak, and the anti-slip ring and the connector housing cannot achieve strong buckling and fixation. The product anti-slip ring is easy to fall off during transportation, use and other working conditions, resulting in failure of the product sealing structure. In addition, even if the anti-slip ring does not fall off, during the plug-in and unplugging process, especially during the oblique plug-in and unplugging process, there are often cases where the sealing rubber ring is pried up, flanging, twisted, and falls off, which also causes the problem of sealing failure. Utility Model Content

[0003] The utility model aims to provide a sealing assembly to solve the problems in the prior art of unreliable connection between the anti-disengagement ring and the connector housing, as well as the sealing rubber ring flanging, twisting, falling off, etc., which lead to sealing failure. At the same time, the utility model also provides a connector to solve the problem that the anti-disengagement ring of the prior art connector is easy to fall off, which leads to the sealing rubber ring falling off and sealing failure.

[0004] The sealing assembly of the utility model comprises a sealing rubber ring and an anti-slipping retaining ring. The sealing rubber ring and the anti-slipping retaining ring are fixedly connected through axial end faces to form an integral structure for being sleeved on the plug-in port of the connector housing. The anti-slipping retaining ring has a connecting portion for bonding or welding with the plug-in port.

[0005] Furthermore, the sealing rubber ring and the anti-slip ring are integrally embedded and formed by plastic compression.

[0006] Furthermore, the sealing rubber ring and the anti-slip ring are bonded and connected.

[0007] Furthermore, the connection portion is the inner side surface of the anti-disengagement ring for plug-in cooperation with the plug-in port.

[0008] Alternatively, the end of the anti-slip ring has an inward-turned edge, and the connecting portion is the inner side surface of the inward-turned edge for cooperating with the end face stop of the plug-in port, or, the connecting portion is the inner side surface of the inward-turned edge for cooperating with the end face stop of the plug-in port and the inner side surface of the anti-slip ring for cooperating with the plug-in port.

[0009] The utility model is a pioneering invention, which connects the sealing rubber ring and the anti-detachment ring by axially aligning them, and at the same time arranging a connection portion on the anti-detachment ring for bonding or welding with the plug-in port of the connector housing. When in use, the sealing rubber ring and the anti-detachment ring are sleeved on the plug-in port as an integral structure, and the anti-detachment ring is connected to the plug-in port by bonding or welding. The fixed connection is relatively reliable, and the anti-detachment ring is avoided from falling off. Moreover, after the sealing rubber ring and the anti-detachment ring are aligned and connected, the sealing rubber ring is constrained by the anti-detachment ring, and the sealing rubber ring will not be flanging, twisting or falling off. The ring state can be reliably maintained as a whole, and the sealing of the plug-in position is guaranteed.

[0010] The connector of the utility model comprises a connector housing, which is provided with a plug-in port for plugging with a matching connector, a sealing rubber ring and an anti-slip ring are sleeved on the outer periphery of the plug-in port, and the anti-slip ring is bonded or welded to the plug-in port.

[0011] Furthermore, the sealing rubber ring and the anti-slip ring are fixedly connected to form an integral structure through the axial end faces.

[0012] Furthermore, the sealing rubber ring and the anti-slip ring are integrally embedded and formed by plastic compression.

[0013] Furthermore, the sealing rubber ring and the anti-slip ring are bonded and connected.

[0014] Furthermore, the connection portion is the inner side surface of the anti-disengagement ring for plug-in cooperation with the plug-in port.

[0015] Alternatively, the end of the anti-slip ring has an inward-turned edge, and the connecting portion is the inner side surface of the inward-turned edge for cooperating with the end face stop of the plug-in port, or, the connecting portion is the inner side surface of the inward-turned edge for cooperating with the end face stop of the plug-in port and the inner side surface of the anti-slip ring for cooperating with the plug-in port.

[0016] The utility model is an improved invention, which improves the bonding strength between the retaining ring and the plug-in port by gluing or welding the retaining ring on the plug-in port, can effectively prevent the retaining ring from falling off during the plug-in process and can also effectively prevent the sealing rubber ring from falling off, thereby ensuring the sealing performance of the connector when it is used.

[0024] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0025] The connector of the utility model aims to solve the problem that the connection between the anti-slip ring 2 at the plug-in port 10 of the existing connector housing 1 is not reliable enough and the anti-slip ring 2 is easy to fall off during the use or transportation of the connector, which causes the sealing rubber ring 3 to also fall off and cause sealing failure. The anti-slip ring 2 is fixedly connected to the plug-in port 10 by bonding or welding. In this way, even if the plug-in port 10 adopts a thin-walled structure, the anti-slip ring 2 can be reliably connected to it, thereby ensuring that the sealing rubber ring 3 is effectively restricted and constrained, which is beneficial to improving the sealing effect.

[0026] Specifically, as shown in the following embodiments, in one embodiment, the anti-slip retaining ring 2 is an axially extending ring structure as a whole, the sealing rubber ring 3 and the anti-slip retaining ring 2 are sequentially mounted on the plug-in port 10 of the connector housing 1 along the plug-in direction, the anti-slip retaining ring 2 cooperates with the retaining edge 11 on the outer surface of the plug-in port 10 to limit the position of the sealing rubber ring 3 in the plug-in direction, and the anti-slip retaining ring 2 is bonded to the circumferential outer side surface corresponding to the plug-in port 10 through its circumferential retaining ring inner side surface 20 by structural adhesive or welded by laser welding or ultrasonic welding. Compared with the existing snap-on connection between the anti-slip retaining ring 2 and the plug-in port 10, the connection is more stable, and the position of the sealing rubber ring 3 can be better constrained, which is conducive to improving the sealing effect. Of course, in other embodiments, the outer end faces of the anti-slip retaining ring 2 and the plug-in port 10 can be set flush, and then bonded or welded at the end faces of the two.

[0027] Figure 6 Another preferred embodiment is shown, in which the anti-slip ring 2 includes an axially extending ring body portion and an inverted edge 22 at the end of the ring body portion. When the anti-slip ring 2 is installed on the plug-in port 10, the inner side surface of the ring body portion fits the plug-in port, and the inner side surface of the inverted edge fits the end face of the plug-in port 10. Based on the structure of such an anti-slip ring, the anti-slip ring 2 can be welded or bonded to the end face of the plug-in port through the inner side surface of the inverted edge 22. That is to say, in this embodiment, the connection part is the inner side surface of the inverted edge for matching with the end face of the plug-in port 10, so it is relatively convenient to weld or bond; or, in order to ensure the reliability of the connection, not only the inner side surface of the inverted edge 22 is welded or bonded to the end face of the plug-in port, but also the inner side surface of the ring body portion of the anti-slip ring and the circumferential outer side surface corresponding to the plug-in port 10 are bonded by structural adhesive or welded by laser welding or ultrasonic welding.

[0028] In actual use, although the above solution avoids the fall-off of the sealing rubber ring 3 caused by the fall-off of the anti-slip ring 2, since the connector housing 1 is a thin-walled housing, the thickness of the sealing rubber ring 3 is also relatively thin, and it is easy to bend, twist, or even fall out of the anti-slip ring when subjected to a large insertion friction force. Therefore, this article further provides a more preferred implementation method, such as Figure 3-5As shown, in this embodiment, the sealing rubber ring 3 and the anti-slip ring 2 are fixedly connected together through the axial end face, for example, it is best to ensure that the inner side surfaces of the two are fixedly connected together in the state of being aligned in the axial direction, to form an integral ring body structure, that is, a sealing assembly, the sealing assembly is integrally mounted on the plug-in port 10, and then the anti-slip ring 2 is bonded or welded to the plug-in port 10 through its inner side surface. In this way, on the one hand, it is ensured that the anti-slip ring 2 will not fall off at will, and the anti-slip ring 2 can also constrain the movement and excessive distortion of the sealing rubber ring 3 through its axial end face, avoiding the situation where it falls off due to flanging or distortion. In this way, it can better ensure that the sealing rubber ring 3 exerts its due sealing performance. Of course, in engineering applications, the inner side surfaces of the sealing rubber ring 3 and the anti-slip ring 2 are not necessarily aligned, for example, the sealing rubber ring 3 protrudes on both the inner and outer sides and is also feasible with the anti-slip ring 2.

[0029] The connection between the anti-slip ring 2 and the sealing rubber ring 3 can be achieved by existing mature process methods such as bonding or integrated inlay plastic compression molding. It can be pre-manufactured into a sealing assembly, and then directly installed on the plug-in port 10 during the manufacturing process of the connector and connected by bonding or welding, which reduces the assembly process and improves production efficiency.

[0030] The embodiment of the sealing assembly of the present invention has the same specific structure as the sealing assembly structure in the embodiment of the connector introduced above, which will not be described in detail herein.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
