[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, a waterproof electrical connector structure of the present invention includes a base plate 1, a shell 2, a rotating block 14 and an electrical connector. The shell 2 is installed on the base plate 1, and an adjustment cavity is formed inside the shell 2. An axial hole communicating with the adjustment cavity is provided on the top surface of the shell 2. The rotating block 14 is arranged inside the adjustment cavity. A shaft rod 13 is installed at the center of the rotating block 14. One end of the shaft rod 13 extends to the outside through the axial hole and is fixedly connected to the electrical connector. The electrical connector includes an upper shell 4 and a lower shell 3. Arc grooves are provided on the opposite surfaces of the upper shell 4 and the lower shell 3. The arc grooves are combined to form a clamping channel. An arc-shaped conductive sheet 6 is installed in the middle of the arc groove. A locking member for pressing the upper shell 4 and the lower shell 3 is installed on one side of the shell 2.

[0021] In this embodiment, arc-shaped mounting grooves are provided on the inner wall surfaces of the openings at both ends of the arc-shaped groove, arc-shaped strips 5 are installed in the mounting grooves, and adjacent arc-shaped strips 5 are combined to form a sealing ring.

[0022] In this embodiment, the locking member includes a screw 8 and a pressure plate 9. A fixing portion 7 is protruded on the outer ring surface of the shell 2, and a screw hole is provided on the fixing portion 7. One end of the screw 8 is threadedly connected to the screw hole, and the other end of the screw 8 is fixedly connected to the pressure plate 9. The other end of the pressure plate 9 is set to contact the top surface of the upper shell 4.

[0023] In this embodiment, a plurality of positioning holes are provided on the bottom surface of the upper shell 4, and a plurality of positioning columns are protruded on the top surface of the lower shell 3. The positioning columns are all inserted into the corresponding positioning holes. The positioning columns and positioning holes can ensure the accuracy between the upper shell and the lower shell, and avoid misalignment between the two.

[0024] In this embodiment, a plurality of slots 15 are provided on the outer ring surface of the rotating block 14, a positioning opening is provided on the outer ring surface of the shell 2, and an insert block 10 is provided in the positioning opening. One end of the insert block 10 is inserted into the corresponding slot 15, and the other end is set to the outside and expanded outward to form a hand-pull portion 11. A compression spring 12 is installed between the inner side surface of the handwheel plate and the shell 2.

[0025] In this embodiment, a plurality of fixing holes are provided on the bottom plate 1 , and screws can pass through the fixing holes to fix the bottom plate on any plane.

[0026] When connecting, rotate the pressure plate to move it away from the top surface of the upper shell. At this time, the upper shell can be opened, and the end of the connecting wire can be inserted into the clamping channel. The wire core on the wire can be inserted into the inner side of the arc-shaped conductive sheet, and the outer layer on the wire can enter the opening of the clamping channel.

[0027] After the above is completed, the pressure plate is rotated in the opposite direction. The rotation of the pressure plate drives the screw, causing the screw to descend and rotate along the screw hole until the pressure plate is against the top surface of the upper shell. The upper shell and the lower shell can be pressed together by the downward pressure of the pressure plate. At this time, the arc-shaped conductive sheet on the wire can be tightly in contact with the core of the wire, and the outer layer on the wire is in contact with the sealing ring. The connection of the wire can be sealed by the extrusion between the sealing ring and the outer layer to ensure waterproofness.

[0028] Among them, after the wire is fixed, the plug block can be pulled outward by the hand-pull part. After the jack is removed from the slot, the electrical connector can rotate around the shaft. The rotation of the shaft drives the rotating block, thereby adjusting the installation angle of the electrical connector, increasing the adaptability when laying the wires. After the angle is determined, the hand-pull part is released, and the plug block can be driven to be inserted into the corresponding slot through the compression spring, thereby positioning the rotating block, shaft and electrical connector after rotation.

[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
