Description

Technical Field

[0001] The utility model belongs to the field of electric connectors, and in particular relates to a side-opening window transfer type charging socket. Background Art

[0002] At present, it has become a common practice for technicians to use high-power charging sockets to increase the charging speed of new energy vehicles. Therefore, in the field of new energy vehicles, technicians have an increasing demand for high-power charging sockets. Traditional high-power charging requires the use of cables with large wire diameters to increase the current carrying capacity of the charging socket. Since the charging socket and the large-diameter cable are usually connected by welding, a charging socket of a single specification can only connect a cable of a single specification. If new energy vehicles want to increase the charging speed, they must use cables with larger wire diameters and charging sockets corresponding to the cables.

[0003] The Chinese invention patent application with application publication number CN115411560A discloses a charging connector. A transfer copper bar is welded at the end of the cable of the charging connector, and a mounting hole is provided on the socket housing. The fastener is inserted into the socket housing from the mounting hole so that the transfer copper bar and the contact piece are fixedly connected as a whole and are conductive to each other, so as to realize the rapid disassembly and assembly of the cable on the charging connector. An opening cover sealing body is provided in the mounting hole, and the buckle cover is fixedly covered on the mounting hole by a snap-on structure, and the sealing of the connection between the buckle cover and the mounting hole is realized by pressing the opening cover sealing body. In order to ensure that the buckle cover can apply sufficient pressing force to the opening cover sealing body, the snap-on connection structure between the buckle cover and the mounting hole must ensure sufficient holding force, which will make it difficult to remove the buckle cover from the mounting hole. At the same time, since the buckle cover is provided on the side of the mounting hole, such a setting is not conducive to the operator to remove the buckle cover to disassemble and assemble the cable, which further increases the difficulty of removing the buckle cover from the mounting hole.

[0029] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0030] The principle of the side-opening window transfer charging socket of the utility model is as follows:

[0031] A side-opening window transfer charging socket, the structure of which can refer to Figure 1-3 As shown. The side-opening transfer charging socket of the utility model specifically includes a socket housing 1. A power cable insertion barrel 5 for inserting a cable 6 is provided on the socket housing 1, and the contact of the side-opening transfer charging socket is fixed on the power cable insertion barrel 5. A transfer copper bar 7 is pre-welded on the connecting end of the cable 6, and a fastener mounting hole 8 is provided on the transfer copper bar 7, so that the transfer copper bar 7 and the contact are fixed and connected through the fastener 10. The inner cavity of the power cable insertion barrel 5 constitutes an installation cavity for the contact to be screwed and connected with the transfer copper bar 7. Both ends of the installation cavity have openings for the contact and the transfer copper bar 7 to extend into the installation cavity. An installation hole 9 is provided on the cavity wall of the installation cavity corresponding to the connection position between the transfer copper bar 7 and the contact, so that the fastener 10 for screwing the transfer copper bar 7 and the contact can be inserted from the outside of the side-opening transfer charging socket. Compared with the prior art, the key point of the present invention is that a sliding opening and closing structure is provided at the opening of the mounting hole 9. The sliding opening and closing structure comprises a sliding slot 12 provided on the edge of the mounting hole 9 and a movable slide plate 13 slidably installed in the sliding slot 12.

[0032] Since the above structure closes and opens the mounting hole 9 by sliding the movable slide plate 13 installed in the sliding slot 12, when disassembling the contact piece and the transfer copper bar 7 of the cable 6, it is only necessary to move the movable slide plate 13 from the outside to open or close the mounting hole 9. Such operation is more concise, and can effectively improve the efficiency of disassembling and assembling the contact piece and the cable 6, thereby improving the efficiency of assembling the charging socket and replacing the cable 6 in the charging socket.

[0033] Based on the above-mentioned principle, the embodiment of the side-opening window transfer charging socket of the utility model is as follows:

[0034] A side-opening window transfer charging socket, the structure of which can refer to Figure 1-3 As shown. The side-opening window transfer charging socket of the utility model specifically includes a socket housing 1. In this embodiment, the socket housing 1 specifically includes a square plate housing 2 with a mounting panel and an insulating housing 3 fixed to the square plate housing 2. A square plate flange 4 is provided on the square plate housing 2 so that the side-opening window transfer charging socket can be installed on the adapter device. The specific structure of the insulating housing 3 can be referred to Figure 8 As shown. It is inserted into the square plate housing 2, with a contact insertion cavity for fixing the contact therein at the front end, and a power cable insertion barrel 5 for accommodating and installing the cable 6 at the rear end. The contact insertion cavity and the power cable insertion barrel 5 are interconnected, and the contact of the side-opening window transfer charging socket is fixedly inserted in the contact insertion cavity, and one end extends into the power cable insertion barrel 5. The other end of the power cable insertion barrel 5 also has an opening, so that the cable 6 connected to the side-opening window transfer charging socket can be inserted.

[0035] A transfer copper bar 7 is pre-welded on the connection end of the cable 6 connected to the side window transfer charging socket, and a fastener mounting hole 8 is provided on the transfer copper bar 7, and a threaded hole corresponding to the fastener mounting hole 8 is provided on the contact. The inner cavity of the power cable insertion barrel 5 constitutes an installation cavity for the contact and the transfer copper bar 7 to be screwed and connected, and the transfer copper bar 7 and the contact are screwed and connected in the installation cavity through the fastener 10. A mounting flange is also provided on the insulating housing 3 so as to be fastened and installed on the square plate housing 2.

[0036] A mounting hole 9 is provided on the wall of the mounting cavity corresponding to the connection position between the transfer copper busbar 7 and the contact piece, so as to allow the aforementioned fastener 10 to be inserted from the outside of the side-opening transfer charging socket. A sliding opening and closing structure is provided at the opening of the mounting hole 9, and a sliding card slot 12 is provided at the edge of the mounting hole 9. The sliding opening and closing structure includes a sliding card slot 12 provided on the edge of the mounting hole 9 and a movable slide 13 slidably installed in the sliding card slot 12, so as to close and open the opening of the mounting hole 9 by sliding the movable slide 13 in the sliding card slot 12. The specific structure of the movable slide 13 can be referred to Figure 4 , Figure 5 shown.

[0037] The side-opening window transfer charging socket also includes a sealing body 36 and a tail cover 35. Before the cable 6 is installed, the sealing body 36 and the tail cover 35 are pre-installed on the cable 6. After the cable 6 is installed in place, the sealing body 36 is inserted into the power cable insertion barrel 5, and the tail cover 35 is buckled on the tail end of the power cable insertion barrel 5 through a buckle structure to ensure the sealing between the cable 6 and the power cable insertion barrel 5.

[0038] The key point of this embodiment is that the sealing plug 14 is installed in the sealing plug of the mounting hole 9. Since the sealing plug 14 can be plugged into the mounting hole 9 alone to achieve sealing, the movable slide plate 13 only needs to block the opening of the mounting hole 9 to prevent the sealing plug 14 from coming out, and there is no need to provide a pressing force to the sealing plug 14, so the sealing plug 14 will not apply a large friction resistance to the movable slide plate 13. In this way, the jamming of the movable slide plate 13 when sliding in the sliding card slot 12 can be reduced, thereby greatly facilitating the disassembly and assembly of the contact member and the transfer copper bus 7 of the cable 6.

[0039] One end of the sliding slot 12 along its extension direction passes through the socket housing 1 so that the movable slide 13 can be inserted into the sliding slot 12; the groove wall at the other end of the sliding slot 12 is matched with one end of the movable slide 13 facing the insertion direction to realize the positioning of the movable slide 13 along its insertion direction. A stop structure is arranged between the movable slide 13 and the socket housing 1 to realize the positioning of the movable slide 13 in the direction opposite to its insertion direction. Such a setting structure is simple and easy to process. On this basis, the stop structure can include a positioning stop convex 15 arranged on the edge of the mounting hole 9, and a positioning card convex 16 arranged on the side of the movable slide 13 facing the mounting hole 9. The positioning stop convex 15 specifically includes a positioning stop surface 18 facing the insertion direction of the movable slide 13 and a first sliding jump surface 17 facing away from the insertion direction of the movable slide 13. The positioning card convex 16 specifically includes a stop mating surface 20 facing away from the insertion direction of the movable slide 13 and a second sliding jump surface 19 facing the insertion direction of the movable slide 13. During installation, as the movable slide plate 13 slides, the first sliding surface 17 and the second sliding surface 19 are pressed against each other. Under the guidance of the first sliding surface 17 and the second sliding surface 19, the positioning protrusion 16 on the movable slide plate 13 can smoothly slide over the positioning stop protrusion 15. After the movable slide plate 13 is inserted into place, the stop mating surface 20 of the positioning protrusion 16 and the positioning stop surface 18 of the positioning stop protrusion 15 are stopped and matched, so that the movable slide plate 13 is positioned and installed at the position of the opening of the closed mounting hole 9. Such a setting can ensure that the movable slide plate 13 can be kept at the position of the opening of the closed mounting hole 9, and avoid the movable slide plate 13 from being opened by mistake when it is acted upon by other external forces. In order to facilitate the positioning and processing of the positioning stop protrusion 15, a mounting boss 11 can be extended outwardly on the edge of the mounting hole 9, and the positioning stop protrusion 15 is arranged on the plane of the mounting boss 11. Of course, the aforementioned stop structure can also be an elastic claw extending outward from the mounting boss 11. After the movable slide plate 13 is installed in place, the elastic claw rebounds and buckles the end surface of the movable slide plate 13 facing away from its insertion direction, so as to realize the positioning of the movable slide plate 13 facing away from its insertion direction.

[0040] The positioning card protrusion 16 needs sufficient insertion force when sliding over the positioning stop protrusion 15. In order to reduce the insertion force, refer to Figure 4 , Figure 5As shown, a cutting groove 21 is provided at one end of the movable slide plate 13 facing away from the insertion direction, so that the end has a cantilever structure 22. The positioning card protrusion 16 is arranged on the cantilever structure 22. When the positioning card protrusion 16 slides over the positioning stop protrusion 15, the cantilever structure 22 can undergo adaptive elastic deformation to reduce the insertion force. Therefore, such a setting is conducive to the installation of the movable slide plate 13, and greatly facilitates the disassembly and assembly of the transfer copper bar 7 of the contact member and the cable 6. On this basis, a rib 23 can be provided on the side of the movable slide plate 13 facing the mounting hole 9 and beside the cantilever structure 22. In this way, the rigidity of the part of the movable slide plate 13 other than the cantilever structure 22 can be strengthened. At the same time, due to the presence of the rib 23, the movable slide plate 13 does not need the entire board surface to contact the hole edge of the mounting hole 9 when sliding, which reduces the friction area between the movable slide plate 13 and the hole edge of the mounting hole 9, thereby effectively reducing the friction resistance between the movable slide plate 13 and the hole edge of the mounting hole 9. This can reduce the jamming of the movable slide plate 13 when sliding in the sliding slot 12, and greatly facilitate the disassembly and assembly of the contact piece and the transfer copper bar 7 of the cable 6. In this embodiment, four cutting grooves 21 are specifically provided at one end of the movable slide plate 13 facing away from the insertion direction, so that the end has two cantilever structures 22. Positioning protrusions 16 are provided on both cantilever structures 22, and two positioning stop protrusions 15 are correspondingly provided on the edge of the mounting hole 9. The rib 23 is provided in the middle of the two cantilever structures 22 to ensure that the movable slide plate 13 has sufficient structural rigidity.

[0041] In addition, a reinforcing rib 24 may also be provided on the side of the movable slide plate 13 facing away from the mounting hole 9. The reinforcing rib 24 can, on one hand, strengthen the rigidity of the movable slide plate 13, making it less likely to deform when sliding, thereby avoiding sliding jamming caused by deformation of the movable slide plate 13. On the other hand, the presence of the reinforcing rib 24 can provide a force point for pushing the movable slide plate 13 to slide, effectively facilitating the disassembly and assembly of the movable slide plate 13.

[0042] The movable slide 13 includes a main body 25 and a sliding part 26 extending from both sides of the main body 25, wherein the sliding part 26 is slidably installed in the sliding slot 12, and the thickness of the sliding part 26 is not greater than the thickness of the main body 25. The main body 25 maintains a sufficient thickness, so that the main body 25 has sufficient rigidity and is not easy to deform when sliding. The thickness of the sliding part 26 is not greater than the thickness of the main body 25, which is beneficial to reducing the friction resistance of the sliding part in the sliding slot 12, thereby reducing the jamming of the movable slide 13 when sliding in the sliding slot 12. Therefore, the above-mentioned setting greatly facilitates the disassembly and assembly of the movable slide 13, and is beneficial to the disassembly and assembly of the contact member and the cable 6 transfer copper bus 7. Of course, in other embodiments, the movable slide 13 can also be set with equal thickness to reduce the difficulty of processing.

[0043] In order to facilitate the insertion of the movable slide plate 13 into the sliding slot 12, the end of the main body 25 facing the insertion direction is provided with a first guide chamfer 27, and the first guide chamfer 27 is located on the side of the main body 25 facing the mounting hole 9. Under the guidance of the first guide chamfer 27, the movable slide plate 13 can easily find the position along the width direction of the sliding slot 12 when inserted into the sliding slot 12. The end of the sliding part 26 facing the insertion direction is provided with a second guide chamfer 28, and the second guide chamfer 28 is located on the side of the sliding part 26 facing the sliding slot 12. Under the guidance of the second guide chamfer 28, the movable slide plate 13 can easily find the position along the depth direction of the sliding slot 12 when inserted into the sliding slot 12. Therefore, the above-mentioned arrangement is conducive to improving the efficiency of the movable slide plate 13 when inserted into the sliding slot 12, and thus is conducive to realizing the disassembly and assembly of the contact member and the cable 6 transfer copper bar 7.

[0044] The socket housing 1 includes two independent mounting cavities, both ends of the two mounting cavities have openings and mounting holes 9 are provided on the cavity walls, and the openings of the mounting holes 9 are provided with the sliding opening and closing structure. When replacing the cable 6, the movable slides 13 on the two power cable insertion barrels 5 can be opened or closed independently, and will not affect each other, so the cables 6 in the two power cable insertion barrels 5 can be independently disassembled. When replacing a single cable 6, this can avoid the cable 6 that does not need to be replaced from being affected, which is conducive to ensuring the structural reliability of the charging socket. On this basis, the opening directions of the mounting holes 9 of the two independent mounting cavities can be opposite to each other, so that the sliding opening and closing structure on the mounting holes 9 on either side has sufficient operating space. Of course, the mounting holes 9 on the two independent mounting cavities can also be oriented in the same direction. The two mounting holes 9 are respectively arranged in the same plane on the same side of the two power cable 6 mounting barrels. A sliding card slot 12 is provided on the plane, and a movable slide 13 is inserted in the sliding card slot 12, so that the two mounting holes 9 can be closed and opened at the same time by the same movable slide 13.

[0045] The aforementioned installation cavity may be provided with an insulating retaining sleeve 29. Figure 6 , Figure 7 As shown, in this embodiment, the insulating retaining sleeve 29 specifically adopts a cylindrical structure adapted to the inner cavity of the power cable insertion tube 5, and its inner cavity is adapted to the shape of the contact piece and the transfer copper bar 7, so as to maintain the position of the fixed contact piece and the transfer copper bar 7 in the insulating retaining tube. A guide groove 30 is opened on the outer wall of the insulating retaining sleeve 29, and the inner wall of the insulating retaining sleeve 29 can be as shown in FIG. Figure 8As shown, a guide block 31 is provided so that the insulating retaining sleeve 29 can be guided and inserted into the power cable insertion barrel 5, and the insulating retaining sleeve 29 is circumferentially fixed relative to the power cable insertion barrel 5. The front end of the insulating retaining sleeve 29 has an insertion hole 32 for the contact to be inserted and a fastener hole 33 for fastening and installing in the power cable insertion barrel 5. After the insulating retaining sleeve 29 is inserted into place, the insulating retaining sleeve 29 is fastened and installed in the power cable insertion barrel 5 by the fastener 10, and one end of the contact extends into the insulating retaining sleeve 29 through the insertion hole 32. A through hole 34 is provided in the insulating retaining sleeve 29 for the insulating retaining sleeve 29 to be opened at the position of the mounting hole 9 on the power cable insertion barrel 5, so that the transfer copper bus 7 of the cable 6 and the contact can be fixed and connected to form a whole through the fastener 10. Since the contact, cable 6 and transfer copper bar 7 are fixed relative to the insulating retaining sleeve 29, and the insulating retaining sleeve 29 is fixed relative to the socket housing 1, when the transfer copper bar 7 and the contact are conductively connected by the fastener 10, as long as the transfer copper bar 7 and the contact are inserted in place, the fastener 10 can be screwed. This avoids the trouble of aligning and adjusting the socket housing 1, the transfer copper bar 7, and the contact before installing the fastener 10, thereby effectively facilitating the disassembly and assembly of the transfer copper bar 7 and the contact. In other embodiments, the insulating retaining sleeve 29 can be integrally formed in the installation cavity.
