Description

Technical Field

[0001] This utility model belongs to the field of electronic connector technology, and specifically relates to an electrical connector. Background Technology

[0002] Electrical connectors are widely used in various electronic devices and electrical systems to achieve reliable connections between circuits. Sometimes, electrical connectors need to be installed by passing through mounting holes on the mounting surface of structural components, and their position must be ensured to be secure.

[0003] One type of connector includes a connector body with a baffle and a retaining clip integrally injection-molded on its outer surface. During installation, the connector body is inserted into a mounting hole on the mounting surface of a structural component. The baffle abuts against one side of the structural component, and the retaining clip engages with the other edge of the mounting hole. The engagement of the retaining clip and the baffle effectively limits the installation of the connector body. While this type of connector allows for quick and easy installation, it has drawbacks: gaps inevitably appear between the connector body and the mounting hole, resulting in a lack of sealing. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical connector with a reasonable structure that can effectively improve the sealing performance between the connector and the mounting hole during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an electrical connector, including an insulating shell with a terminal mounting cavity. A limiting baffle protruding outwardly is integrally arranged around the outer circumference of the insulating shell. A fixing buckle is provided on one side of the limiting baffle on the insulating shell. A sealing gasket is provided on the side of the limiting baffle facing the fixing buckle. Both the side of the sealing gasket facing the limiting baffle and the side facing the fixing buckle have an adhesive layer. The sealing gasket is a sponge double-sided adhesive or foam double-sided adhesive. A raised edge is provided on the limiting baffle around the sealing gasket.

[0007] Preferably, the sealing gasket protrudes beyond the retaining edge in its thickness direction.

[0008] Preferably, the side of the limiting baffle facing away from the sealing gasket has a protruding rib.

[0009] Preferably, there are two fixing buckles, which are symmetrically arranged on opposite sides of the insulating shell.

[0010] Preferably, one end of the terminal mounting cavity is provided with an inlet for inserting conductive terminals, and a terminal blocking part is provided inside the terminal mounting cavity away from the inlet; an elastic buckle is provided inside the terminal mounting cavity extending toward the terminal blocking part, and the end of the elastic buckle is provided with a backstop block for blocking and limiting the conductive terminals.

[0011] The positive effects of this utility model are as follows: The electrical connector structure of this utility model is reasonably designed. During actual installation, the electrical connector is inserted into the mounting hole on the mounting surface. The electrical connector is fixed by the cooperation of the fixing buckle and the limiting baffle. At the same time, the two sides of the sealing gasket are tightly bonded to the limiting baffle and the mounting surface and are pressed, which can effectively seal the gap between the limiting baffle and the mounting surface and also play a role in strengthening the fixation. The setting of the baffle can play a role in resisting and limiting the sealing gasket, preventing the sealing gasket from shifting and affecting the sealing performance. Attached Figure Description

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] The electrical connector structure in this embodiment of the utility model is as follows: Figures 1 to 5 As shown, it includes an insulating shell 1 with a terminal mounting cavity 10. During assembly, conductive terminals (not shown) are inserted into the terminal mounting cavity 10 to conduct electricity. The conductive terminals are used to conduct electricity. A limiting baffle 11 protruding outward is integrally arranged around the outer circumference of the insulating shell 1. A fixing buckle 12 is provided on one side of the limiting baffle 11 on the insulating shell 1. A sealing gasket 13 is provided on the side of the limiting baffle 11 facing the fixing buckle 12. The sealing gasket 13 facing the limiting baffle 11 and facing the fixing buckle 12 are connected. Both sides of the mounting surface 2 have an adhesive layer. The sealing gasket 13 and the limiting baffle 11 are bonded together by the adhesive layer. For example, the sealing gasket 13 can be made of sponge double-sided adhesive or foam double-sided adhesive. The limiting baffle 11 has a raised edge 14 around the sealing gasket 13. Preferably, the edge 14 and the limiting baffle 11 are integrally formed. In this embodiment, the electrical connector structure is reasonably designed. During actual installation, the electrical connector is inserted into the mounting hole 21 on the mounting surface 2. The electrical connector is fixed by the cooperation of the fixing buckle 12 and the limiting baffle 11 (see...). Figure 6 As shown, the sealing gasket 13 is tightly bonded to the limiting baffle 11 and the mounting surface 2 on both sides and is pressed, which can effectively seal the gap between the limiting baffle 11 and the mounting surface 2, and at the same time play a role in strengthening the fixation; the retaining edge 14 can play a role in resisting and limiting the sealing gasket 13, preventing the sealing gasket 13 from shifting and affecting the sealing performance.

[0023] See Figure 5 As shown, the limiting baffle 11 has a protruding rib 15 on the side facing away from the sealing gasket 13. The protruding rib 15 provides effective support for the limiting baffle 11 to enhance its strength. To further ensure the reinforcing effect of the protruding rib 15, the protruding rib 15 is strip-shaped, with one end connected to the side wall of the insulating shell 1 and the other end extending to be flush with the outer edge of the limiting baffle 11.

[0024] The sealing gasket 13 can be further configured in its thickness direction (i.e., Figure 1 The gasket 13 protrudes from the retaining edge 14 in the vertical direction shown, so that the sealing gasket 13 can be effectively squeezed during the installation of the electrical connector to ensure the sealing effect.

[0025] like Figure 3 and Figure 6 As shown, in order to enhance the stability of the electrical connector during installation in this embodiment, it is preferable to provide two fixing buckles 12, which are symmetrically arranged on opposite sides of the insulating shell 1.

[0026] In some embodiments, see Figure 4 As shown, one end of the terminal mounting cavity 10 is provided with an inlet 101 for inserting conductive terminals. A terminal abutment 102 is provided inside the terminal mounting cavity 10 away from the inlet 101. An elastic buckle 103 extending towards the terminal abutment 102 is provided inside the terminal mounting cavity 10. The end of the elastic buckle 103 is provided with a backstop block 104 for stopping and limiting the conductive terminal. During production, the conductive terminal is inserted into the terminal mounting cavity 10 through the inlet 101. The front end of the conductive terminal abuts against the terminal abutment 102, and the backstop block 104 at the end of the elastic buckle 103 stops against the conductive terminal to prevent the conductive terminal from slipping backward.

[0027] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
