Description

Technical Field

[0001] The utility model relates to the technical field of rectangular connectors, in particular to a rectangular connector structure. Background Art

[0002] Rectangular connector is a common electrical connector with a rectangular shell. It is widely used in electronic equipment and industrial automation. Due to its sturdy structure, high degree of standardization, and good connection performance, rectangular connector has become an indispensable electrical connection solution in a variety of equipment.

[0003] After searching, a Chinese patent discloses a rectangular connector sealing structure, and its authorization announcement number is (CN221447562U). It is configured to have a connector extending in front of the rectangular body of the connector. A mounting groove for adapting to the sealing frame is formed near the connector near the rectangular body. The sealing frame is made of silicone material and includes a frame body and a convex portion formed on the periphery of the frame body, and a groove formed on the inner wall of the frame relative to the convex portion. The sealing frame is configured in the mounting groove so that the groove forms a closed space.

[0004] This patent sets up the mutual cooperation between the plug-in part, the installation groove, the sealing frame, the frame body, the protrusion, the groove, the recess and the rib. The rectangular main body and the plug-in part protrude from the installation groove, the sealing frame is arranged in the installation groove and is closely connected to the rectangular main body and the plug-in part. The two protrusions of the sealing frame protrude from the plug-in part and fill the installation groove after being squeezed to achieve the gap between the sealing related components. However, in actual use, the existing rectangular connector generally adopts an integrated structure, but it is too inconvenient to replace the internal components in the later stage, resulting in reduced efficiency of the rectangular connector and greatly shortened service life, making this patent not conducive to actual use.

The two first fixing plates 3 and the two second fixing plates 7 are respectively in conflict with the two sides of the connecting plate 2. A locking assembly is provided between both sides of the first shell 4 and the second shell 8. The two sides of the connecting plate 2 and the inner wall of the inner shell 13 are respectively fixedly connected with a core 1 6 and the insert 6, the insulator 5 is fixedly connected on both sides of the connecting plate 2 and located between the inner walls of the inner shell 13, the core 16 and the insert 6 respectively pass through the two insulators 5, and positioning holes 14 are provided on both sides of the inner shell 13 and located on one side of the connecting plate 2. A fixing hole 18 is provided on one side of the two second fixing plates 7, and the two fixing holes 18 respectively pass through the two second fixing plates 7, and a fixing column 20 is fixedly connected on one side of the two first fixing plates 3. The two fixing columns 20 respectively pass through the two positioning holes 14 and the two fixing holes 18, and elastic washers 15 are fixedly connected on both sides of the connecting plate 2 and located on the outside of the inner shell 13, and the outer sides of the two elastic washers 15 are in contact with the inner sides of the first outer shell 4 and the second outer shell 8 respectively.

[0024] When the rectangular connector is in use, first, the two positioning holes 14 and the two fixing holes 18 are respectively sleeved on the outside of the two fixing columns 20 to achieve the positioning effect, and then the first shell 4 and the second shell 8 are respectively fixed on both sides of the connecting plate 2 through two locking components, so that the two first fixing plates 3 and the two second fixing plates 7 are respectively in contact with the two sides of the connecting plate 2, thereby forming the connector body 1, and then the two elastic gaskets 15 on both sides of the connecting plate 2 and located on the outside of the inner shell 13 are used to ensure the sealing of the connector during use, and the two insulators 5 are used to avoid leakage of the core 16 and the tube 6 during use, thereby ensuring the safety and efficiency of the rectangular connecting block.

[0025] like Figure 1-Figure 5As shown, the two locking assemblies include four mounting plates 10, which are respectively fixed on both sides of the first shell 4, and a through hole 17 is provided on one side of the four mounting plates 10. The four through holes 17 respectively penetrate the four mounting plates 10, and two rotating blocks 11 are rotatably connected between the four mounting plates 10.
