Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a multi-functional module anti-misinsertion structure for bus-type electrical connectors. Background Technology

[0002] Currently, in the electronics field, it is common to see multiple sets of connectors of the same model installed. Since each set of connectors has a different function, if connectors with different functions are inserted incorrectly during installation, the connectors will not work properly, and may even cause hardware to burn out, or even cause explosions, fires and other hazards.

[0003] For example, a patent with authorization announcement number CN221080539U describes an electrical connector with anti-misinsertion function, including a base plate, a connector, and a socket. It connects the socket and the connector by aligning the connector plate with the limiting hole at the bottom of the socket, thus avoiding misinsertion. However, it prevents misinsertion by using a single connector plate connected to the bottom of the socket. If it is only used for connectors with fewer sockets, there is not much of a problem. If it is used for connectors with more sockets, multiple connector plates of different shapes are required to connect with the limiting holes of the corresponding shapes, which makes the manufacturing process more complicated. Moreover, if there are similar shapes, misinsertion may also occur during connection, reducing the practicality of the device.

[0004] Based on this, a multi-functional module anti-misinsertion structure for bus-to-electrical connectors is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5 As shown, a multi-functional module anti-misinsertion structure for a bus connector includes a socket 1, a connector 11 inserted into the top of the socket 1, a first arc-shaped plate 12 symmetrically fixedly connected to the outer wall of the socket 1, a second arc-shaped plate 14 symmetrically fixedly connected to the outer wall of the connector 11, the positions of the first arc-shaped plate 12 and the second arc-shaped plate 14 corresponding to each other, an anti-disengagement mechanism 2 symmetrically provided on the outer wall of the socket 1, and a fixing mechanism 3 provided at the top of the second arc-shaped plate 14.

[0027] In this embodiment, the anti-detachment mechanism 2 can prevent the socket 1 and the plug 11 from being connected and then disconnected, making the connection between the socket 1 and the plug 11 more stable. Then, the fixing mechanism 3 can fix the limiting rod 15 to prevent the limiting rod 15 from falling off the second arc plate 14. At the same time, the limiting rod 15 can be disassembled to avoid errors during installation that prevent disassembly.

[0028] In an optional embodiment, such as Figure 2 and Figure 4As shown, the top of the first arc-shaped plate 12 is uniformly and fixedly connected with fixing blocks 13, and the inner wall of the fixing blocks 13 is provided with insertion holes. The inner wall of the second arc-shaped plate 14 is uniformly inserted with limiting rods 15, and the positions of the limiting rods 15 and the fixing blocks 13 are corresponding. The outer wall of the limiting rods 15 is inserted into the inner wall of the fixing blocks 13, and the shape of the insertion holes on the inner wall of the fixing blocks 13 is adapted to the shape of the limiting rods 15. The number of holes in the fixing blocks 13 can be selected according to the needs for subsequent differentiation, and the shape of each hole can be controlled, so that the cooperation between the fixing blocks 13 and the limiting rods 15 can be diversified.

[0029] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the anti-disconnection mechanism 2 includes a connecting block 21. The outer wall of the connecting block 21 is fixedly connected to the outer wall of the socket 1. A rotating rod 22 is rotatably connected to the connecting block 21 near the outer wall of the socket 1. A rotating plate 24 is fixedly connected to the outer wall of the rotating rod 22. A torsion spring 23 is symmetrically sleeved on the outer wall of the rotating rod 22. One end of the torsion spring 23 is fixedly connected to the outer wall of the connecting block 21, and the other end is fixedly connected to the outer wall of the rotating plate 24. During the connection process between the socket 1 and the plug 11, the outer wall of the plug 11 contacts the inclined surface of the outer wall of the plug 25, causing the plug 25 to drive the rotating plate 24 to rotate. The rotating plate 24 drives the rotating rod 22 and the torsion spring 23 to rotate synchronously. After the plug 11 and the socket 1 are connected, the rotating plate 24 rebounds under the action of the torsion spring 23, causing the outer wall of the plug 25 to insert into the inner wall of the plug 11, thereby restricting the connection between the socket 1 and the plug 11.

[0030] In an optional embodiment, such as Figure 2 and Figure 3 As shown, a plug block 25 is fixedly connected to the outer wall of the rotating plate 24 near the plug 11. The outer wall of the plug block 25 has a plug-in joint with the outer wall of the plug 11. The plug block 25 is trapezoidal in shape. The shape of the plug block 25 causes the plug block 25 to rotate to one side when the outer wall of the plug 11 contacts the inclined surface of the outer wall of the plug block 25.

[0031] In an optional embodiment, such as Figure 2 , Figure 4 and Figure 5As shown, the fixing mechanism 3 includes a fixing plate 31. The top end of the fixing plate 31 is fixedly connected to the top end of the second arc-shaped plate 14. Bolts 32 are threaded onto the inner wall of the fixing plate 31. A fixing ring 34 is fixedly connected to the bottom end of the fixing plate 31. A mounting plate 35 is fixedly connected to the bottom end of the fixing ring 34. Four elastic pieces 36 are evenly distributed at the bottom end of the mounting plate 35. The outer wall of the elastic pieces 36 is inserted into the inner wall of the limiting rod 15. When the limiting rod 15 and the second arc-shaped plate 14 are connected, the outer wall of the limiting rod 15 is... The inner wall of the second arc-shaped plate 14 is inserted into the inner wall of the limiting rod 15, so that the outer wall of the elastic piece 36 is inserted into the inner wall of the limiting rod 15. Then, the bolt 32 is rotated so that the bolt 32 moves downward on the inner wall of the fixing plate 31, which drives the abutment block 33 to move downward at the same time, so that the abutment block 33 supports the elastic piece 36. In this way, the outer wall of the limiting block 37 is engaged with the inner wall of the limiting rod 15, preventing the limiting rod 15 from falling off. Thus, the position of the limiting rod 15 can be adjusted as needed to avoid the inability to reuse it after a single installation error.

[0032] In an optional embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, a clamping block 33 is rotatably connected to the bottom end of the bolt 32. The outer wall of the clamping block 33 is slidably connected to the inner wall of the elastic piece 36. The clamping block 33 can restrict the elastic piece 36, so that the outer wall of the elastic piece 36 is in tight contact with the inner wall of the limiting rod 15.

[0033] In an optional embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, a limiting block 37 is fixedly connected to the outer wall of the elastic sheet 36. The outer wall of the limiting block 37 is engaged with the inner wall of the limiting rod 15. The limiting block 37 is trapezoidal in shape. By engaging the outer wall of the limiting block 37 with the inner wall of the limiting rod 15, the limiting rod 15 can be prevented from separating from the second arc plate 14.

[0034] The above embodiment discloses a multi-functional module anti-misinsertion structure for a bus-to-electrical connector. When connecting the socket 1 and the connector 11, the position and bottom shape of the limiting rod 15 are observed to identify the corresponding fixing block 13, thus preventing misinsertion during connection. During connection, the outer wall of the connector 11 contacts the inclined surface of the outer wall of the plug 25, causing the plug 25 to rotate the rotating plate 24. The rotating plate 24 then rotates the rotating rod 22 and the torsion spring 23 synchronously. After the connector 11 and socket 1 are connected, the rotating plate 24 rebounds under the action of the torsion spring 23, causing the outer wall of the plug 25 to engage with the inner wall of the connector 11, thereby restricting the connection between the socket 1 and the connector 11 and preventing separation. When connecting the limiting rod 15 and the second arc-shaped plate 14, the limiting rod 15... The outer wall of the limiting block 37 is inserted into the inner wall of the second arc plate 14, allowing the elastic piece 36 to be inserted into the inner hole of the limiting rod 15. Then, the bolt 32 is rotated, and the bolt 32 moves downward in the fixing plate 31, causing the clamping block 33 to move downward synchronously, so that the clamping block 33 supports the elastic piece 36. This allows the outer wall of the limiting block 37 to engage with the inner wall of the limiting rod 15, preventing the limiting rod 15 from falling off. Thus, the position of the limiting rod 15 can be adjusted as needed, avoiding the inability to reuse it after a single installation error. In summary, the anti-detachment mechanism 2 can prevent the socket 1 and the plug 11 from detaching after being connected, making the connection between the socket 1 and the plug 11 more stable. Then, the fixing mechanism 3 can fix the limiting rod 15, preventing the limiting rod 15 from falling off the second arc plate 14. At the same time, the limiting rod 15 can be disassembled, preventing the inability to disassemble it due to errors during installation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
