Description
Technical Field
[0001] The utility model relates to the technical field of charging sockets, in particular to a sealing plugging structure for a screw through hole of a charging socket. Background Art
[0002] As a key component of electric vehicles, the charging socket has a complex structure and many parts, and needs to be connected with screws during assembly. This requires the design of screw holes on the insulator. In order to meet the protection level of the charging socket, the screw holes need to be sealed after installation.
[0003] Currently, most sealing plugs are made of pure silicone material. In order to ensure that the sealing plug does not fall off during use, it is necessary to add a part at the tail to limit it, which makes the assembly process more complicated. In addition, most screw holes are straight holes and lack a limiting structure, which makes it easy for the sealing plug to collapse during assembly, causing sealing failure. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a charging socket screw hole sealing plugging structure.
[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a charging socket screw through hole sealing plug structure, comprising a screw through hole arranged on an insulator and a sealing cover for sealing, the screw through hole is provided with a countersunk hole at the port located on the outer wall of the insulator, the hole wall of the countersunk hole is symmetrically provided with two limiting grooves on the insulator, the sealing cover comprises a top cover and a sealing ring fixed on the top cover, the side of the top cover adjacent to the sealing ring is a stop surface matched with the bottom surface of the countersunk hole, two symmetrically arranged connecting blocks are protruding outward on the outer periphery of the stop surface, an anti-sway block is protruding from the end of the connecting block toward the side of the top cover away from the sealing ring, and the width of the anti-sway block is consistent with the groove width of the limiting groove.
[0006] By adopting the above technical scheme, a countersunk hole and a limiting groove are arranged at the screw through-hole, and a stop surface and an anti-sway block are arranged on the top cover. The stop surface cooperates with the bottom surface of the countersunk hole to limit the top cover in the axial direction of the screw through-hole, so as to prevent the sealing cover from collapsing into the screw through-hole; the anti-sway block cooperates with the limiting groove to limit the top cover in the circumferential direction of the screw through-hole, so as to prevent the sealing cover from rotating or swaying in the screw through-hole, causing unilateral compression of the sealing ring and affecting the sealing effect; the overall structural design is simple, and during installation, you only need to align the anti-sway block of the top cover with the limiting groove, and the operation is convenient and quick.
[0007] Furthermore, the outer ring of the stop surface is provided with a guide bevel.
[0008] By adopting the above technical solution, a guiding bevel is set on the outer ring of the stop surface, so that it plays a guiding role when the top cover is inserted into the screw hole, which is convenient for installation.
[0009] Furthermore, a stop boss is provided on the insulator near the limiting groove. The stop boss is L-shaped as a whole and cooperates with the outer wall of the insulator to form a slot. The end of the anti-sway block protrudes outward and is provided with a fixed card plate. The fixed card plate is placed in the slot to form a limiting fit.
[0010] By adopting the above technical solution, a stop boss and a fixed clamping plate are set. When installing the sealing cover, the fixed clamping plate is clamped into the groove formed by the stop boss and the outer wall of the insulator, thereby limiting the top cover in the axial direction of the screw through hole to prevent the top cover from falling off.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0023] like Figure 1-7 As shown, an embodiment of the present application discloses a sealing plugging structure for a screw through hole 11 of a charging socket, comprising a screw through hole 11 arranged on an insulator 10 and a sealing cover 20 for sealing. The screw through hole 11 is used to install a screw, and the sealing cover 20 is used to cover the screw through hole 11 and seal it to ensure the protection level and prevent water, dust and other debris from entering the screw through hole 11 and affecting the screw.
[0024] Specifically, a countersunk hole 12 is provided at the end of the screw through hole 11 located on the outer wall of the insulator 10, and the aperture of the countersunk hole 12 is larger than the aperture of the screw through hole 11, so that a step is formed at the outer end of the screw through hole 11. Two limiting grooves 13 are symmetrically opened on the insulator 10 at the hole wall of the countersunk hole 12, and a stop boss 14 is provided on the insulator 10 adjacent to the limiting groove 13. The stop boss 14 is L-shaped as a whole, and its L-shaped notch cooperates with the outer wall of the insulator 10 to form a card slot 15.
[0025] The sealing cover 20 includes a top cover 21 and a sealing ring 22. The sealing ring 22 is fixedly arranged on the top cover 21 by secondary plastic coating. An annular sealing rib 28 is arranged on the outer wall of the sealing ring 22 to improve the strength of the sealing ring 22. The sealing rib 28 is in contact with the inner wall of the screw through hole 11 to improve the sealing performance between the two. The side of the top cover 21 adjacent to the sealing ring 22 is provided with a stop surface 23 that matches the bottom surface of the countersunk hole 12. The stop surface 23 is a circular surface as a whole, and its diameter is consistent with the inner diameter of the countersunk hole 12. When installed, the stop surface 23 is in contact with the bottom surface of the countersunk hole 12, so as to limit the top cover 21 in the axial direction of the screw through hole 11 and prevent the sealing cover 20 from collapsing into the screw through hole 11. A guide bevel 26 is arranged on the outer circle of the stop surface 23, so that when the sealing cover 20 is installed into the screw through hole 11, the top cover 21 can be easily entered into the countersunk hole 12 by the guiding effect of the guide bevel 26, thereby improving the convenience of installation. Two symmetrically arranged connecting blocks 24 are provided on the outer periphery of the stop surface 23, and an anti-sway block 25 is provided on the end of the connecting block 24, which is provided to protrude toward the side of the top cover 21 away from the sealing ring 22. The width of the anti-sway block 25 is consistent with the width of the limiting groove 13. When installing the sealing cover 20, the anti-sway block 25 cooperates with the limiting groove 13 to limit the top cover 21 in the circumferential direction of the screw through hole 11, so as to prevent the sealing cover 20 from rotating or swinging in the screw through hole 11, causing unilateral compression of the sealing ring 22 and affecting the sealing effect. A fixed card plate 27 is also provided on the end of the anti-sway block 25, and when installing the sealing cover 20, the fixed card plate 27 is clamped into the card groove 15 formed by the stop boss 14 and the outer wall of the insulator 10, so as to limit the top cover 21 in the axial direction of the screw through hole 11, so as to prevent the top cover 21 from falling off.
[0026] The present application achieves the limitation of the top cover 21 in the axial direction of the screw through hole 11 by cooperating with the fixing card plate 27 and the card slot 15, so that the top cover 21 cannot move in the axial direction of the screw through hole 11 after installation, thereby preventing the sealing cover 20 from falling outward after installation; the top cover 21 is limited in the axial direction of the screw through hole 11 by the contact between the stop surface 23 and the bottom surface of the countersunk hole 12, thereby preventing the sealing cover 20 from collapsing; the top cover 21 is limited in the circumferential direction of the screw through hole 11 by cooperating with the anti-sway block 25 and the limiting groove 13, thereby preventing the sealing cover 20 from rotating or swinging in the screw through hole 11 after installation, thereby preventing the sealing ring 22 from being compressed on one side. The structure of the entire sealing cover 20 is also relatively simple. When installing, you only need to insert the top cover 21 and the sealing ring 22 into the screw through hole 11, and align the anti-sway block 25 and the fixing card plate 27 with the limiting groove 13 and the card slot 15 respectively, which is convenient to operate.
[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
