Technical Field

[0001] This invention relates to the field of vehicle socket technology, and more specifically to a charging socket with a switch. Background Technology

[0002] Vehicle sockets are used in automobiles to provide power to various electrical appliances to meet users' power needs. For example, Chinese utility model patent application number CN201720096907.1 discloses a high- and low-voltage connection socket for a vehicle compressor and a vehicle compressor. The high- and low-voltage connection socket for the vehicle compressor includes: a socket housing, with a high-voltage section and a low-voltage section on the socket housing. The high-voltage section includes a core passing through the socket housing and a shielding member sleeved on the outer peripheral surface of the core. The core has at least two high-voltage terminals spaced apart. The low-voltage section includes at least two low-voltage terminals passing through the socket housing and spaced apart. Most existing vehicle sockets are directly powered by cable connections, while sockets with on / off switches have a more complex structure, resulting in a larger socket size. Summary of the Invention

The support shell 4 has a support plate 32 flush with the left end of the limiting arc plate 28. The support plate 32 and the left end of the limiting arc plate 28 together form a plane for the right end of the reaction spring 14 to abut. A spring washer 33 is fitted on the copper rod 9 between the soft flat wire 11 and the sealing weld plate 24. The left end of the reaction spring 14 abuts against the spring washer 33. The support shell 4 has a first adapter plate 34 and a second adapter plate 35 connected to each other. A micro switch 36 is provided on the first adapter plate 34. One end of the second adapter plate 35 is connected to the coil frame 16, and the other end extends out of the support shell 4. A plastic sleeve 37 that can abut against the copper rod 9 is fitted on the round plate 19. A positioning piece 38 is provided on the soft flat wire 11. A linkage 49 that can actuate the micro switch 36 is provided at the lower part of the positioning piece 38.The upper end of the flexible flat cable 11 is fixed with a rivet nut 39. The upper end of the outer shell 1 is provided with an opening 26 groove. The outer shell 1 is provided with channels 41 that allow the first cable 2 and the second cable 3 to be inserted and communicate with the opening 26 groove. The flexible flat cable 11 passes through the support shell 4 and is located above the opening 26 groove. The rivet nut 39 is located in the space enclosed by the opening 26 groove and the support frame. The first cable 2 and the second cable 3 are welded with connecting pieces 42 that are inserted into the corresponding opening 26 groove. The connecting pieces 42 and the rivet nut 39 are provided with threaded holes 43 that are aligned with each other, and are screwed into the threaded holes 43. The screw-fixed connecting piece 42 and the rivet nut 39 are provided. The outer shell 1 contains an alignment card 44 and multiple limiting pieces 45 for restricting the movement of the electromagnetic mechanism 7. The support shell 4 has an alignment opening 46 for inserting the alignment card 44. Multiple buckles 47 are provided on both the left and right inner walls of the outer shell 1. The lower ends of the buckles 47 can abut against the support shell 4 and the sealing plate 27 to complete the sealing and fixing of the support shell 4 and the sealing plate 27. The outer shell 1 has multiple mounting holes 48. The first power lead-out terminal 5, the second power lead-out terminal 6, and their stationary contact 13 are integrally formed.

[0019] In this embodiment, power is switched on and off between the first cable 2 and the first power lead-out 5, and between the second cable 3 and the second power lead-out 6, respectively, so that the charging socket has a switching function. The internal structure such as the relay is located between the support shell 4 and the outer shell 1, which is compact and small in size, realizing lightweight design and saving production materials. When the electromagnetic mechanism 7 is energized, the moving iron core 10 drives the push rod 8 to move to the right. When the push rod 8 moves, it first contacts the copper rod 9 and then pushes the copper rod 9 to move to the right so that the moving contact 12 abuts against the stationary contact 13, realizing the connection of the first cable 2, connecting piece 42, copper rod 9, moving contact 12, stationary contact 13 and the first power lead 5, as well as the connection of the second cable 3, connecting piece 42, copper rod 9, moving contact 12, stationary contact 13 and the second power lead 6. At this time, the first power lead 5 and the second power lead 6 form a power socket. The soft flat wire 11 has a deformation function, which enables it to adapt to the movement of the copper rod 9. When the electromagnetic mechanism 7 is de-energized, the copper rod 9 returns to the left under the action of the reaction spring 14, so that the moving contact 12 is separated from the stationary contact 13. The moving iron core 10 and the push rod 8 return to the left under the action of the return spring 20. This external structure of the reaction spring 14 makes fuller use of the internal space of the support shell 4, making the overall structure of the charging socket smaller. The ceramic cover 22 is used to extinguish the electric arc generated when the moving contact 12 and the stationary contact 13 are working. The bellows 25 can extend or retract with the movement of the copper rod 9, so that the sealing plate 24, the bellows 25 and the ceramic cover 22 always form a sealed space, effectively preventing the electric arc from leaking out and damaging other internal components, and ensuring high safety. When assembling the first power lead-out terminal 5 and the second power lead-out terminal 6, first insert the guide limiting protrusion 31 of the first power lead-out terminal 5 and the second power lead-out terminal 6 into the slot 30 of the corresponding opening 26, and then insert the limiting arc plate 28 of the sealing plate 27 into the support shell 4 to complete the limiting of the first power lead-out terminal 5 and the second power lead-out terminal 6. At the same time, the slot 30 can also limit the displacement of the first power lead-out terminal 5 and the second power lead-out terminal 6, resulting in better structural stability. When the electromagnetic mechanism 7 is energized, the copper rod 9 moves to the right, which can drive the soft flat wire 11, the positioning piece 38 and the linkage 49 to move to the right, so that the moving contact 12 contacts the stationary contact 13. At the same time, the linkage 49 opens the micro switch 36. When the electromagnetic mechanism 7 is de-energized, the copper rod 9, the soft flat wire 11, the positioning piece 38 and the linkage 49 return to the left under the action of the reaction spring 14, so that the moving contact 12 disengages from the stationary contact 13. At the same time, the linkage 49 disengages from the micro switch 36, and the micro switch 363 replaces the auxiliary contact, transmitting signals through the first adapter plate 34 and the second adapter plate 35. The connecting piece 42 and the rivet nut 39 are detachably fixed by screws, which not only makes the connection structure more stable and firm, but also facilitates assembly and subsequent maintenance; When assembling the support shell 4 and the outer shell 1, the support shell 4, which has been assembled with the electromagnetic mechanism 7 and other structures, is inserted into the outer shell 1. During the insertion process, alignment is performed by the alignment card 44 and the alignment opening 46 to facilitate assembly. After insertion, the electromagnetic mechanism 7 is limited by multiple limiting pieces 45, resulting in better structural stability. At the same time, the lower end of the buckle 47 abuts against the support shell 4 and the sealing plate 27 to complete the encapsulation and fixation of the support shell 4 and the sealing plate 27. The buckle 47 is designed to facilitate later maintenance, and the mounting hole 48 is designed to facilitate the installation of the charging socket. The first power lead 5, the second power lead 6, and their stationary contact 13 are integrally formed, reducing process steps and saving materials.
