Technical Field

[0001] The utility model relates to the technical field of connector sealing, and more specifically, to a waterproof sealing component and a plugging device. Background Art

[0002] The inside of a charging plug for a new energy vehicle is connected to a battery, and the socket of the charging plug faces the outside of the vehicle for connection to an external power source to charge the battery. To improve battery safety, the charging plug usually undergoes multiple layers of waterproof protection. In addition to the sealed connection between the internal electric components, the outside of the socket also needs to be sealed.

[0003] Especially for the external protection of the socket, it can ensure that the socket still maintains good waterproof effect under harsh weather conditions (such as rain and snow) and different environments (such as outdoor parking lots and during sea transportation), so as to prevent moisture or debris from entering the socket, thereby protecting the internal electrical connections and electronic components from damage and ensuring the safety and performance of the battery. Summary of the Utility Model

[0004] The utility model provides a waterproof sealing component and a plugging device for externally sealing and protecting the plugged charging interface, thereby protecting the internal electrical connections and electronic components from damage.

[0005] To achieve the above object, the technical solution provided by the utility model is as follows:

[0006] A waterproof sealing component includes a protective member. The protective member includes a bottom surface and a protective platform located on one side of the bottom surface. A plugging cavity is recessed on the side of the protective platform away from the bottom surface. The protective platform is also provided with a skirt around its circumference, and there is a gap one between the skirt and the protective platform. Two opposite and straight side edges of the skirt are at different heights relative to the bottom surface.

[0007] The waterproof sealing component in this solution is used to cooperate with the connection socket. The skirt can cooperate with the outer opening of the socket of the connection socket, so that the charging interface is completely protected inside the waterproof sealing component, and the charging interface is externally sealed and protected to protect the internal electrical connections and electronic components from damage.

[0008] Preferably, the other two opposite side edges of the skirt are in an "S" shape, and lugs are connected to these side edges; the lugs are located at one of the arc segments of these side edges. The lugs can cooperate with the lug seats on the connection socket, can indicate from the outside that the waterproof sealing component is assembled in place, and can also prevent the waterproof sealing component from falling off.

[0009] Preferably, a plurality of positioning rib positions are provided on the inner side of one of the straight side edges of the skirt. The positioning rib positions are used to cooperate with the positioning ribs on the connection socket.

[0010] Preferably, a partition is provided in the socket cavity, and a plurality of reinforcing ribs are respectively provided on both sides of the partition. The reinforcing ribs can enhance the structural strength of the partition, and when the socket cavity is connected and pressed against the protective member in cooperation with the plug, the pressing effect at the partition is better.

[0011] Preferably, one end of the end face of the partition also recesses towards the direction close to the bottom surface to form a second partition. The provision of the second partition makes the end face of the partition 13 uneven, for anti-misinstallation.

[0012] Preferably, the end face of the protective platform is further connected to a second protective platform, and the second protective platform is connected to three of the side faces of the end face of the protective platform.

[0013] Furthermore, for the two opposite and straight side edges of the skirt, the side edge closer to the bottom surface is side edge one, and the other side edge is side edge two; the end faces of two opposite side faces of the second protective platform are inclined, and the end face gradually approaches the protective platform in the direction of side edge one towards side edge two; the side face of the second protective platform having a non-inclined end face is arranged close to side edge two of the skirt. The additional protective platform increases the contact area between the waterproof sealing component and the socket, improving the sealing and protection effect.

[0014] Preferably, a plurality of locking protrusions are provided on the inner circumference of the socket cavity at intervals. The setting positions and the number of the locking protrusions on the opposite side faces inside the socket cavity correspond to each other; the protruding height of the locking protrusions is 0.15 - 0.5 mm. When the socket and the waterproof sealing component are connected, when the plug is connected and matched with the socket cavity, there is an interference amount between the locking protrusions and the plug, so that the socket cavity generates a radial thrust on the plug through the locking protrusions. On the one hand, the position of the plug is centered, and on the other hand, the plug is stably and firmly connected with the socket cavity in cooperation.

[0015] Preferably, sealing rings are also provided on the protective platform and the second protective platform, and the orientation of the sealing rings is arranged along the orientation of the skirt. The provision of the sealing rings can improve the sealing effect between the waterproof sealing component and the socket on the one hand, and can also effectively adjust the internal and external pressure differences during the installation process of the waterproof sealing component on the other hand, making the waterproof sealing component easier to install.

[0016] The present utility model also provides a plugging device, including a socket and the waterproof sealing component according to any one of the above; the socket includes a base and a housing connected to the base.

[0033] Embodiment 1

[0034] As Figure 1 and Figure 2 shown, a waterproof sealing assembly provided in this embodiment is cooperatively connected with the charging interface of a socket and is used for waterproof sealing protection of the charging interface.

[0035] Specifically, as Figure 5 shown, a waterproof sealing assembly includes a protection member 1. The protection member 1 includes a bottom surface and a protection platform 12 located on one side of the bottom surface. A socket cavity 10 is recessed on the side of the protection platform 12 away from the bottom surface. The protection platform 12 is also circumferentially provided with a skirt 11, and there is a first gap between the skirt 11 and the protection platform 12. Two opposite and straight side edges of the skirt 11 are at different heights relative to the bottom surface.

[0036] The waterproof sealing assembly is used to be cooperatively connected with a socket 2. The socket 2 includes a base and a housing 21 connected to the base. An installation platform is provided inside the housing 21, and there is a second gap between the housing 21 and the installation platform. At least one plug 22 protrudes from the installation platform; when the socket 2 is connected to the waterproof sealing assembly, the plug 22 is cooperatively connected with the socket cavity 10, the housing 21 is located at the first gap between the skirt 11 and the protection platform 12, and the protection platform 12 is located at the second gap between the housing 21 and the installation platform. In this embodiment, the side edges of the opening of the housing 21 of the socket 2 are not flush. By setting two opposite and straight side edges of the skirt 11 at different heights relative to the bottom surface, the skirt 11 can be mutually matched with the opening of the housing 21, so that the charging interface can be completely protected inside the waterproof sealing assembly, and external sealing protection is carried out on the charging interface to protect the internal electrical connections and electronic components from damage.

[0037] Combined with Figure 6 As shown, when the skirt 11 is provided, the skirt 11 has two opposite and straight side edges and two opposite and "S"-shaped side edges, and the two opposite and straight side edges are at different heights relative to the bottom surface. Specifically, with reference to the bottom surface, the side edge of the skirt 11 that is closer to the bottom surface among the two opposite and straight side edges is side edge one, and the other side edge is side edge two. One end of the "S"-shaped side edge is connected to side edge one, and the other end is connected to side edge two after two bends during the extension process, and the bending places are arc-shaped.

[0038] Combined with Figure 3 and Figure 5 As shown, lugs 111 are provided on the "S"-shaped side edge of the skirt 11, and the lugs 111 are located at one of the arc segments of this side edge. The lugs 111 are provided at the bent arc segments, so that both ends of the lugs 111 can be connected to the straight line segments at both ends of the arc segment to the greatest extent, enabling the lugs 111 to play a role in strengthening the structure of the skirt 11 at the same time.

[0039] The length of the lugs 111 is set at 10 mm, making the shape change of the lugs 11 easier and making the lugs 11 more easily cooperate and connect with the structure on the socket 2. Specifically, a lug seat 23 is also provided on the outer side of the corresponding side plate of the housing 21. After the waterproof sealing component is cooperatively connected to the socket 2, the lugs 111 are hung on the lug seat 23, which is used to indicate from the outside that the waterproof sealing component is assembled in place, and the cooperative connection between the lugs 111 and the lug seat 23 can also prevent the waterproof sealing component from falling off. In another case, as Figure 7 shown, the cooperation part between the lugs 11 and the lug seat 23 is widened to improve the structural strength of the lugs 11.

[0040] As a further improvement, three positioning rib positions 112 are provided on the inner side of one of the straight side edges of the skirt 11. Specifically, the positioning rib positions 112 are provided on side edge one. In addition, three positioning ribs 24 protrude from the outer side of the side edge of the housing 21 of the socket 2 that cooperates with side edge one. After the housing 21 is cooperatively connected to the gap one between the skirt 11 and the protective platform 12, the positioning rib positions 112 and the positioning ribs 24 are cooperatively connected at the same time. In other cases, the positioning rib positions 112 and the positioning ribs 24 can also be set to other quantities.

[0041] Combined with Figure 4 As shown, a partition 13 is also provided in the plug socket cavity 10. The partition 13 divides the plug socket cavity 10, so as to be correspondingly connected to the plug 22. Moreover, a number of strengthening ribs 131 are provided on both sides of the partition 13. The strengthening ribs 131 can strengthen the structural strength of the partition 13, and when the plug socket cavity 10 is cooperatively connected to the plug 22 and the protective member 1 is pressed, the pressing effect at the partition 13 is better.

[0042] In addition, one end of the end face of the partition plate 13 is also recessed towards the direction close to the bottom surface to form a second partition plate 130, so that the end face of the partition plate 13 is not flush. The non-flush end face of the partition plate 13 needs to cooperate with other structures on the connector plug 22, so that anti-misalignment installation can be achieved through the non-flush end face of the partition plate 13.

[0043] As Figure 5 and Figure 6 shown, the end face of the protective platform 12 is also connected to a second protective platform 14, and the second protective platform 14 is connected to three of the side faces of the end face of the protective platform 12. Specifically, the second protective platform 14 has three side faces, and the end faces of two opposite side faces are inclined. The end face of the second side edge of the skirt 11 gradually approaches the protective platform 12 in the direction of the first side edge. The side face of the second protective platform 14 with a non-inclined end face is arranged close to the second side edge of the skirt 11. The addition of the protective platform 12 increases the contact area between the waterproof sealing component and the socket 2, improving the sealing and protection effect.

[0044] A sealing ring 15 is also provided on the protective platform 12 and the second protective platform 14, and the extending direction of the sealing ring 15 is along the extending direction of the skirt 11. The sealing ring 15 surrounds the outside of the protective platform 12 and the second protective platform 14 at the same time. The sealing ring 15 can be integrally formed with the protective platform 12 and the second protective platform 14, or can be separately provided by an O-ring. On the one hand, the setting of the sealing ring 15 improves the sealing effect between the waterproof sealing component and the socket 2, and on the other hand, it can also effectively adjust the internal and external pressure difference during the installation process of the waterproof sealing component, making the waterproof sealing component easier to install.

[0045] A plurality of locking protrusions 121 are protruded at intervals in the circumferential direction around the inner side wall of the plug cavity 10, and the setting positions and the setting numbers of the locking protrusions 121 on the opposite side faces of the inner side of the plug cavity 10 correspond to each other. In a preferred embodiment, the locking protrusion 121 is in the shape of a protruding round package, and the protruding height of the locking protrusion 121 is 0.3 mm. When the socket 2 is connected to the waterproof sealing component, when the connector plug 22 is in fit connection with the plug cavity 10, there is an interference amount of 0.3 mm between the locking protrusion 121 and the connector plug 22, so that the plug cavity 10 generates a radial thrust on the connector plug 22 through the locking protrusion 121. On the one hand, the position of the connector plug 22 is centered, and on the other hand, the connector plug 22 is stably and firmly connected to the plug cavity 10 in fit.

[0046] Specifically, the waterproof sealing structure is a soft rubber sealing structure, which is made of an elastic material, such as a rubber material. The setting of the locking protrusion 121 can make the waterproof sealing structure and the socket fit with each other in the center, and at the same time make the side faces where the connector plug 22 and the plug cavity 10 are connected to each other fit tightly, so as to achieve a good sealing effect.

[0047] It should be noted that in other cases, the protruding height of the locking protrusion 121 can also be set to 0.15 mm, 0.5 mm, etc., and the range of the protruding height of the locking protrusion 121 is 0.15 - 0.5 mm. On the one hand, it can generate a radial thrust on the docking socket 2, and on the other hand, it is necessary to enable the protective member 1 and the socket 2 to be cooperatively connected.

[0048] In this embodiment, the protective member 1 is integrally formed, for example, it can be manufactured by means of die casting. The integrally formed protective member 1 can make the connection between the various components in the waterproof and sealing assembly more firm, and can also make the appearance of the waterproof and sealing assembly better.

[0049] Embodiment 2

[0050] Combined with Figure 1 and Figure 2 As shown, this embodiment provides a plugging device, which includes a mating socket 2 and the waterproof and sealing assembly described in Embodiment 1. The socket 2 includes a base and a housing 21 connected to the base. An installation table is provided inside the housing 21, and there is a second gap between the housing 21 and the installation table. At least one plug 22 protrudes from the installation table; when the socket 2 is connected to the waterproof and sealing assembly, the plug 22 is cooperatively connected with the plugging cavity 10, the housing 21 is located at the first gap between the skirt 11 and the protective table 12, and the protective table 12 is located at the second gap between the housing 21 and the installation table.

[0051] Usually, the socket 2 is fixedly installed on the fixing surface 3. After the socket 2 is cooperatively connected with the waterproof and sealing assembly, the charging interface is completely protected inside the protective member 1, so as to perform external sealing protection on the charging interface to protect the internal electrical connection and electronic components from damage.

[0052] The terms "installation", "setting", "providing", and "connection" referred to here should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, components or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0053] The above schematically describes the present invention and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to this technical solution without creative work without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
