Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an MSD single-proof socket. Background Technology

[0002] A search revealed a Chinese utility model patent with application number 201921477748.5, which describes an assembly and sealing structure for an MSD manual maintenance switch protective cover. The socket and the protective cover are connected via a snap-fit ​​mechanism, which consists of interlocking clamping components and limiting components. The clamping components are located on the inner wall of the protective cover, and the limiting components are located on the end face of the socket. The side wall of the protective cover has pre-drilled openings for copper busbars to pass through, and these openings communicate with the end face of the protective cover. Each opening contains a protective rubber plug, the end of which is in contact with the end face of the socket. Therefore, while this method achieves sealing by blocking the openings with protective rubber plugs, it requires sealing in multiple areas, resulting in poor sealing performance. Furthermore, it requires the use of a protective cover, thus its structure and sealing performance require further optimization. Utility Model Content

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0021] Please see Figure 1-8 This utility model provides an embodiment of an MSD single-proof socket, including a plug housing 1, wherein a terminal block assembly 3 is provided inside the plug housing 1; the terminal block assembly 3 includes a terminal board 30, a copper busbar group 31 is provided on one side of the terminal board 30, and a fixing part 32 is provided on the other side of the terminal board 30; a sealing ring 33 is also provided between the copper busbar group 31 and the fixing part 32, and when the terminal block assembly 3 is inserted into the mounting seat 7 provided on the plug housing 1, the sealing ring 33 seals the gap between the mounting seat 7 and the terminal board 30.

[0022] In summary, when the terminal block assembly 3 is installed with the mounting base 7, the sealing ring 33 on the terminal block assembly 3 can seal the gap between the mounting base 7 and the terminal block assembly 3. Therefore, compared with the prior art, the external structure of the socket is simplified, the sealing point is only one mounting base 7, and the sealing ring 33 is located inside the mounting base 7. The sealing performance of the socket is improved by reducing the number of sealing points.

[0023] Furthermore, the plug housing 1 is also provided with a fixing seat 9, and a bolt 5 is installed on the fixing seat 9; when the nut installed on the bolt 5 is tightened, the terminal block assembly 3 moves downward, thereby pressing the sealing ring 33 against the fixing part 32 and the support part 8 provided inside the plug housing 1. Therefore, by tightening the nut on the bolt 5, the fixing part 32 can be used to press the sealing ring 33, thereby further improving the sealing performance of the sealing ring 33 on the socket.

[0024] To prevent the sealing ring 33 from shifting freely after being installed on the terminal block 30, the terminal block assembly 3 also includes a bracket 34, which confines the sealing ring 33 to the copper busbar assembly 31. Therefore, by connecting the bracket 34 to the terminal block 30, the sealing ring 33 is confined between the copper busbar assembly 31 and the bracket 34, so as to prevent the sealing effect from being affected by the free movement of the sealing ring 33 during the installation of the terminal block assembly 3.

[0025] Furthermore, to facilitate the installation and fixation of the bracket 34 and the terminal block 30, the bracket 34 includes a first part 37 and a second part 38; wherein, one end of the first part 37 and the second part 38 are provided with a hook 36, and the other end of the first part 37 and the second part 38 are provided with a locking pin 310. Since the bracket 34 is divided into two parts, the first part 37 and the second part 38 can be installed from both sides of the terminal block 30 respectively. At the same time, when the locking pin 310 on the first part 37 is connected to the hook 36 on the second part 38, the bracket 34 can be installed on the terminal block 30.

[0026] Furthermore, since both the first part 37 and the second part 38 have pins 39 on their facing surfaces, and these pins 39 are adapted to and connected to the sockets 35 on the terminal block 30, the pins 39 and sockets 35 are adapted to and connected to prevent the bracket 34 from moving on the terminal block 30. Because the position of the bracket 34 is fixed, the position of the sealing ring 33 can be reliably fixed using the bracket 34, thereby facilitating the deformation of the sealing ring 33 under pressure.

[0027] To ensure that the terminal block assembly 3 can be stably and reliably located in the mounting base 7, the inner wall of the cover plate 4 is also provided with a buckle 6, and the buckle 6 is adapted to and connected with the buckle groove 2 provided on the plug housing 1. Therefore, when the cover plate 4 is connected to the plug housing 1, the cover plate 4 presses on the bracket 34 to prevent the bracket 34 from shaking in the mounting base 7. While ensuring the reliable sealing of the sealing ring 33, the terminal block assembly 3 can also be reliably fixed in the plug housing 1.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
