Description

Technical Field

[0001] The utility model belongs to the technical field of electrical connectors or signal connectors, and particularly relates to a leak-proof connector. Background Art

[0002] In some special fields or environments, circuit or signal lines need to pass through a cavity filled with foaming agent. In order to facilitate the connection of lines on the cavity wall, it is usually necessary to install a connector on the cavity wall. For example, in the refrigerator field, some customers need to clamp the female end of the connector on the refrigerator inner liner. To prevent the refrigerator foaming agent from leaking into the refrigerator box body, generally double-sided brushed glue foam is used on the market at present, and the glue layer is protected by tissue paper to prevent the glue from being contaminated and the viscosity from decreasing when used at the client side, so that it cannot be closely attached to the panel. If the centrifugal force of the tissue paper is too large, it will be difficult for employees to tear the tissue paper, affecting the working hours. If the centrifugal force is small, there is a risk of falling off, resulting in a decrease in viscosity and inability to be closely attached to prevent foaming agent leakage. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is how to set the connector so that the connector is convenient to install and has a good sealing effect.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A leak-proof connector includes a connector body. A pressing plate extending outward is provided on the side of the connector body. A sealing member is provided on one side of the pressing plate. At least one clamping member is provided on at least one side of the connector body. The clamping member has a fixed end connected to the connector body and a free end. There is a gap for the free end to move between the free end and the connector body. A clamping portion is provided on the clamping member. The clamping portion is in clamping cooperation with the carrier connected to the connector body to press the pressing plate against the sealing member.

[0006] Preferably, the clamping member extends obliquely outward from the fixed end to the free end, and the clamping portion is provided on the outer side of the free end.

[0007] Preferably, the clamping portion is provided with a plurality of clamping positions, and the distances between each clamping position and the pressing plate are different.

[0008] Preferably, there are two clamping members, which are symmetrically arranged on opposite sides of the connector body.

[0009] Preferably, the distances between the outer edges of the corresponding clamping positions of the two clamping members are different, and the distance at the end close to the pressing plate is small, and the distance at the other end gradually increases.

[0010] Preferably, the clamping positions on the clamping member form a stepped structure.

[0011] Preferably, a clamping protrusion for buckling with another connector is further provided on one side of the connector body.

[0012] Preferably, the seal is an elastic foam, and the side of the seal close to the pressing plate is adhesively connected to the surface of the pressing plate.

[0013] Preferably, the pressing plate and the connector body are integrally formed, the seal is in an annular structure, and is adhesively connected to the outer edge of the pressing plate.

[0014] The beneficial effects of the present utility model are as follows: by providing a clamping member on the connector body, the clamping member and the pressing plate can cooperate to clamp the entire connector body on the carrier connected thereto. In this way, the connection is not only more firm, but also convenient and fast. It is not necessary to apply glue to both sides of the seal, nor to tear the face paper during installation, thus improving the installation efficiency. Description of the Drawings

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] Please refer to Figure 1 and Figure 2, shown in the figure is a connector provided on a refrigerator. The connector includes a male connector 1 and a female connector 2. There is a structure for mutual snap connection between the male connector 1 and the female connector 2. Specifically in this embodiment, a clamping projection 22 for snap connection with the male connector 1 is provided on one side of the connector body 21 of the female connector 2. Wiring terminals are provided inside the connector bodies 21 of both the male connector 1 and the female connector 2, and the wiring terminals between them are electrically connected to each other after the male connector 1 and the female connector 2 are connected. The wiring terminal part belongs to the prior art and will not be elaborated in detail here. It is worth noting that a pressing plate 23 extending outward is provided on the side of the connector body 21. In this embodiment, the pressing plate 23 and the connector body 21 are integrally injection molded. A sealing member 24 is provided on one side of the pressing plate 23. The sealing member 24 is an elastic foam. The pressing plate 23 and the connector body 21 are integrally formed. The sealing member 24 is a ring structure and is bonded to the outer edge of the pressing plate 23. A clamping member 25 is provided on at least one side of the connector body. The clamping member 25 has a fixed end connected to the connector body and a free end. There is a gap for the free end to move between the free end and the connector body 21 so that the free end can generate elastic deformation. A clamping portion 251 is provided on the clamping member 25. The clamping portion 251 is in clamping cooperation with the carrier connected to the connector body 21 to press the pressing plate 23 against the sealing member 24. In the present utility model, only glue needs to be brushed on the bottom surface of the elastic foam to realize the paste connection with the pressing plate 23 surface of the female plastic shell, and then the glued female end is inserted into the clamping plate 3 of the refrigerator. The structure of the present utility model is simple, without worrying about the problem of the face paper falling off and being difficult to tear, and without considering the problem of glue viscosity causing material leakage, saving working hours.

[0020] In this embodiment, the clamping member 25 extends obliquely outward from the fixed end to the free end, and the clamping portion 251 is provided on the outside of the free end. The inclined setting of the clamping member 25 enables the connector to play a guiding role when inserted into the refrigerator clamping plate 3, making it easier to insert, and the clamping member 25 can be automatically and slowly squeezed during insertion.

[0021] In this embodiment, the clamping portion 251 is provided with a plurality of clamping positions, and the distances between each clamping position and the pressing plate 23 are different. There are two clamping members 25, and they are symmetrically arranged on opposite sides of the connector body 21. The distances between the outer edges of the corresponding clamping positions of the clamping portions 251 of the two clamping members 25 are different, and the distance at the end close to the pressing plate 23 is small, and the distance at the other end gradually increases. The clamping positions on the clamping member 25 form a stepped structure. By means of the steps shaped like wings on the female end and squeezing the elastic foam, through the compression and rebound of the foam, various thicknesses of the clamping plate 3 can be adapted to achieve a tight fit of the clamping plate, effectively preventing the foaming agent from leaking into the outside of the housing in the refrigerator housing.
