Description

Technical Field

[0001] This utility model relates to the field of new energy charging connector technology, and in particular to a pin-type plug-in charging connector. Background Technology

[0002] A pin-type pluggable charging connector is a connection device that achieves circuit conduction and completes the charging function by precisely mating and separating pins with corresponding interfaces.

[0003] Existing pin connectors have a limited number of insertion and removal cycles (usually only a few thousand), which is insufficient to meet the high-frequency usage requirements of mobile charging devices. Individual terminal contacts are few in number (generally only a few), making them prone to momentary interruptions under driving vibrations, severely impacting the stability and reliability of signal transmission in new energy vehicles. Furthermore, their protective performance is inadequate, with low dust and water resistance after insertion, making them susceptible to poor contact due to environmental impurities. They lack automatic alignment and angle compensation mechanisms, requiring extremely high assembly precision and exhibiting poor versatility. The high-voltage circuit lacks real-time temperature rise detection, resulting in insufficient safety redundancy. Moreover, most connections are manually inserted and removed, leading to low operational efficiency and making them unsuitable for intelligent automated charging scenarios. Utility Model Content

[0004] In view of the problems of limited plug-in and plug-out cycles, few individual terminal contacts, easy instantaneous breakage, and insufficient protection performance of the above-mentioned or existing technologies, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick-release mechanism, which includes two rear cover plates. Two mutually pluggable first insulating mounting plates and second insulating mounting plates are provided at opposite ends of the two rear cover plates. The first insulating mounting plate is provided with an aluminum mounting plate at one end of the rear cover plate. The second insulating mounting plate is provided with a plurality of pre-compression components for adjusting the floating size and angle at one end of the rear cover plate. The pre-compression components are provided with a plurality of guide components for quick docking at the end away from the rear cover plate. A grounding component is provided between the plurality of guide components.

[0006] A high-voltage and low-voltage connection mechanism includes a high-voltage pin terminal and a high-voltage socket terminal fixedly disposed at opposite ends of a first insulating mounting plate and a second insulating mounting plate and capable of being plugged into each other, as well as a low-voltage pin terminal and a low-voltage socket terminal. Each of the high-voltage socket terminal and the low-voltage socket terminal is provided with a contact spring, and a protective component is provided on the high-voltage pin terminal.

[0007] In a preferred embodiment of the pin-type plug-in charging connector of this utility model, the pre-compression assembly includes a fixed aluminum plate disposed on the outer side of one end of the second insulating mounting plate located on the rear cover plate, an upper cover plate disposed on the fixed aluminum plate away from the rear cover plate, a floating aluminum plate disposed on the upper cover plate within the cavity of the fixed aluminum plate, and a spiral spring disposed on the floating aluminum plate away from the upper cover plate.

[0008] In a preferred embodiment of the pin-type plug-in charging connector of this utility model, the guide assembly includes a guide post riveted to a floating aluminum plate, and a guide sleeve riveted to a first insulating mounting plate is inserted into the end of the guide post away from the floating aluminum plate.

[0009] In a preferred embodiment of the pin-type plug-in charging connector of this utility model, the grounding component includes a grounding pin terminal disposed inside the first insulating mounting plate, and the end of the grounding pin terminal away from the first insulating mounting plate is connected to a grounding socket terminal that is fixedly connected to the second insulating mounting plate.

[0010] As a preferred embodiment of the pin-type plug-in charging connector of this utility model, the protective component includes an insulating anti-touch cover disposed on the head of the high-voltage pin terminal, and a temperature probe wire bundle disposed in a small hole opened in the center of the high-voltage pin terminal.

[0011] As a preferred embodiment of the pin-type plug-in charging connector of this utility model, the high-voltage socket terminal and the low-voltage socket terminal head are both provided with spring fixing members that are fixedly connected to the contact finger spring.

[0012] As a preferred embodiment of the pin-type plug-in charging connector of this utility model, wherein: a sealing gasket is provided on one side of the mounting aluminum plate on the rear cover plate, and O-rings are provided at the insertion end of the first insulating mounting plate and the second insulating mounting plate, as well as at the connection point with the mounting aluminum plate and the connection point with the high-voltage pin terminal.

[0013] The beneficial effects of this novel pin-type pluggable charging connector are as follows:

[0014] 1. The scroll spring in the pre-compression assembly can drive the floating aluminum plate to flexibly adjust its size and angle. Combined with the precise docking of the guide post and guide sleeve in the guide assembly, the connector can automatically align and compensate for angles even if there are installation deviations during insertion and removal. It can be inserted smoothly without strict alignment, which greatly reduces the assembly difficulty. At the same time, in the high and low voltage connection mechanism, the contact finger springs in the high-voltage and low-voltage socket terminals increase the number of contacts, making the contact more stable during insertion and removal. This reduces the instantaneous power failure during vehicle vibration and can withstand more insertion and removal cycles. It is more durable than ordinary connectors and is suitable for frequently used scenarios.

[0015] 2. During the insertion and removal process, the grounding pin terminals and grounding socket terminals of the grounding component will be connected in advance to achieve pre-grounding, ensuring electrical safety. The insulating anti-touch cover in the protective component can prevent accidental contact with high-voltage parts, and the temperature detection harness monitors the temperature of the high-voltage terminals in real time, so that any abnormalities can be detected in time. In addition, the sealing gaskets on the mounting aluminum plate and the O-rings in various places can keep dust and water out, so even in dusty or humid environments, it is not easy to have poor contact problems, making signal and power transmission more stable and reliable.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a pin-type pluggable charging connector, which can shorten operation time, enable automatic plugging and unplugging, improve the fault tolerance and versatility of the charging mechanism, and reduce assembly precision requirements. It includes a quick-release mechanism, which includes two rear cover plates 10. Two mutually pluggable first insulating mounting plates 11 and second insulating mounting plates 12 are provided at opposite ends of the two rear cover plates 10. The first insulating mounting plate 11 is provided with a mounting aluminum plate 13 at one end of the rear cover plate 10. The second insulating mounting plate 12 is provided with a plurality of pre-compression components 14 for adjusting the floating size and angle at one end of the rear cover plate 10. The pre-compression component 14 includes a fixed aluminum plate 141 provided on the outer side of the second insulating mounting plate 12 at one end of the rear cover plate 10. An upper cover plate 142 is provided at the end of the fixed aluminum plate 141 away from the rear cover plate 10. A floating aluminum plate 143 is provided in the inner cavity of the upper cover plate 142 within the fixed aluminum plate 141. A spiral spring 144 is provided at the end of the floating aluminum plate 143 away from the upper cover plate 142.

[0027] Specifically, the mounting aluminum plate 13 is the main mounting component of the pin end, with four mounting holes for overall installation, a groove on the back for installing the sealing gasket 27, and four threaded holes for installing the first insulating mounting plate 11. Two guide sleeves 152 are riveted on it for guiding when it is inserted with the other end. The fixing aluminum plate 141 is the main body for mounting and fixing the pin end. The through holes on the four corners of the fixing aluminum plate 141 are for mounting the pin end. The middle is a hollow cavity with four cylindrical bosses. There are two threaded holes on each of the four sides of the aluminum plate for mounting and fixing the upper cover plate 142 (fixed by Phillips countersunk screws).

[0028] The floating aluminum plate 143 is installed inside the hollow cavity of the fixed aluminum plate 141. Four spiral springs 144 are installed between the floating aluminum plate 141 and the fixed aluminum plate 141 for adjusting the floating size and angle. The spiral springs 144 are pre-compressed after installation. Large shims are installed on the four protrusions on the fixed aluminum plate 141 to make the floating aluminum plate 143 float downward within the size. Two guide posts 151 are riveted to the floating aluminum plate 143 to play a guiding role and float together with the floating aluminum plate 143.

[0029] The second insulating mounting plate 12 is made of insulating material and serves to install, fix, and insulate the plug terminals. A rectangular flange in the middle is used to fix the second insulating mounting plate 12 to the floating aluminum plate 143 with four screws. Both ends are elliptical. One end is inserted into the first insulating mounting plate 11, and the elliptical tail end is fastened to the rear cover plate 10 by a buckle.

[0030] Furthermore, the pre-compression assembly 14 is provided with a plurality of guide assemblies 15 for quick docking at the end away from the rear cover plate 10. The guide assembly 15 includes a guide post 151 riveted to the floating aluminum plate 143, and a guide sleeve 152 riveted to the first insulating mounting plate 11 is inserted into the end of the guide post 151 away from the floating aluminum plate 143.

[0031] The gap between the guide post 151 and the guide sleeve 152 ensures accurate guidance during insertion, and the guide sleeve 152 can always maintain its containment and guidance when the guide post 151 floats with the floating aluminum plate 143, thus avoiding jamming during insertion.

[0032] Preferably, a grounding component 16 is provided between a plurality of guide components 15. The grounding component 16 includes a grounding pin terminal 161 disposed inside the first insulating mounting plate 11. The end of the grounding pin terminal 161 away from the first insulating mounting plate 11 is inserted into a grounding socket terminal 162 which is fixedly connected to the second insulating mounting plate 12.

[0033] It should be noted that both the grounding pin terminal 161 and the low-voltage pin terminal 22 have barbs on their outer circumferences to prevent them from coming off after installation with the first insulating mounting plate 11; similarly, the grounding socket terminal 162 and the low-voltage socket terminal 23 have barbs on their outer circumferences to prevent them from falling off after installation with the second insulating mounting plate 12. Furthermore, the rear cavity of the first insulating mounting plate 11 will be filled with epoxy resin after the low-voltage pin terminal 22 and the grounding pin terminal 161 are installed, providing further fixation and sealing.

[0034] In use, when a charging connection operation is required, firstly, the guide post 151 riveted to the floating aluminum plate 143 in the guide assembly 15 will align and gradually insert into the guide sleeve 152 on the mounting aluminum plate 13. As the two ends continue to approach, the first insulating mounting plate 11 and the second insulating mounting plate 12 begin to gradually insert. During this process, if there is a certain size deviation or angle deviation at both ends, the pre-compression assembly 14 will immediately activate the adjustment function. This is because the floating aluminum plate 143 is installed in the hollow cavity of the fixed aluminum plate 141 by four spiral springs 144, and the spiral springs 144 are in a pre-compression state after installation. When the floating aluminum plate 143 is subjected to a force from the direction of the first insulating mounting plate 11, the spiral springs 144 will deform accordingly according to the deviation, causing the floating aluminum plate 143 to float in the hollow cavity of the fixed aluminum plate 141, thereby realizing the adjustment of size and angle.

[0035] Meanwhile, the large shims installed on the four protrusions on the fixed aluminum plate 141 will limit the floating range of the floating aluminum plate 143, ensuring that it floats downward within a reasonable size. The guide post 151 will float together with the floating aluminum plate 143, and the guide sleeve 152 can always maintain the containment and guidance of the guide post 151, effectively avoiding jamming during the insertion process.

[0036] During the insertion process, the grounding component 16 will work synchronously. The grounding pin terminal 161 inside the first insulating mounting plate 11 will be accurately inserted into the grounding socket terminal 162 on the second insulating mounting plate 12 to achieve pre-grounding and ensure the safety of the entire charging connection process. Since the outer circles of the grounding pin terminal 161 and the grounding socket terminal 162 are designed with barbs, it can ensure that they are firmly installed on their respective insulating mounting plates and will not fall off.

[0037] Once the parts are properly inserted, the sealing gasket 27 in the groove on the back of the mounting aluminum plate 13 will fit tightly against the corresponding component, providing a good seal. At the same time, the first insulating mounting plate 11 and the second insulating mounting plate 12 are stably connected through their respective fixing structures. The elliptical tail end of the second insulating mounting plate 12 is fastened to the rear cover plate 10 by a snap fastener, ensuring the stability of the overall structure.

[0038] When separation is required, the two ends are gradually pulled apart under the action of external force. The guide post 151 exits from the guide sleeve 152, and the spiral spring 144 will return to its original shape by its own elasticity, driving the floating aluminum plate 143 back to the initial position, preparing for the next connection. Throughout the process, the floating adjustment function of the pre-compression component 14 greatly improves the fault tolerance and versatility of the charging mechanism and reduces the requirements for assembly precision. At the same time, the precise guidance of the guide component 15 and the stable cooperation of each component enable rapid docking and effectively shorten the operation time.

[0039] Example 2, refer to Figures 1 to 7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a high-low voltage connection mechanism for a pin-type pluggable charging connector. This solves the problem of insufficient pluggable / pluggable cycles, momentary interruptions during vibration, and the resulting impact on the stability of signal transmission in new energy vehicles. The mechanism includes a high-low voltage connection mechanism comprising a high-voltage pin terminal 20 and a high-voltage socket terminal 21 fixedly disposed at opposite ends of a first insulating mounting plate 11 and a second insulating mounting plate 12, and capable of being plugged into each other; and a low-voltage pin terminal 22 and a low-voltage socket terminal 23. Both the high-voltage socket terminal 21 and the low-voltage socket terminal 23 are provided with a contact spring. Spring 24, a protective component 25 is provided on the high voltage pin terminal 20. The protective component 25 includes an insulating anti-touch cover 251 provided on the head of the high voltage pin terminal 20, and a temperature probe wire bundle 252 provided in a small hole in the center of the high voltage pin terminal 20. The heads of the high voltage socket terminal 21 and the low voltage socket terminal 23 are provided with spring fixing members 26 that are fixedly connected to the contact finger spring 24. The mounting aluminum plate 13 is provided with a sealing gasket 27 on one side of the rear cover plate 10. The first insulating mounting plate 11 and the second insulating mounting plate 12 are inserted at one end, and O-rings 28 are provided at the connection points with the mounting aluminum plate 13 and the connection points with the high voltage pin terminal 20.

[0040] Specifically, the high and low voltage terminals and the grounding terminals are installed on the first insulating mounting plate 11. The first insulating mounting plate 11 is made of insulating material and serves to install, fix, and insulate the pin terminals. A rectangular flange in the middle is fixed to the mounting aluminum plate 13 by four screws. The two ends are elliptical. The outer circle of the end that intersects with the second insulating mounting plate 12 has a groove for installing an O-ring 28, which prevents dust from entering the contact body after interlocking. Another O-ring 28 is fitted under the rectangular flange to seal the first insulating mounting plate 11 and the mounting aluminum plate 13 after they are fixed.

[0041] The high-voltage pin terminal 20 is installed in the round holes on both sides of the ellipse of the first insulating mounting plate 11, and is cylindrical in shape. The head is equipped with an insulating anti-contact cover 251, and the tail is crimped with a high-voltage cable. There is a small hole in the center of the circle to install the temperature detection wire harness 252. After the temperature detection wire harness 252 is installed, the electronic wire is led out from the small hole on the side. The high-voltage pin terminal 20 is also fitted with an O-ring 28 for sealing with the first insulating mounting plate 11. After the high-voltage pin terminal 20 is installed in the first insulating mounting plate 11, the rear cover plate 10 can be fastened to fix it. The outer circle of the low-voltage pin terminal 22 and the grounding pin terminal 161 are designed with barbs to prevent them from coming out after installation with the first insulating mounting plate 11. After the two are installed, the cavity at the tail of the first insulating mounting plate 11 is filled with epoxy resin glue to further fix and seal the terminals.

[0042] The second insulating mounting plate 12 has elliptical ends. One end is inserted into the first insulating mounting plate 11, and the elliptical tail end is fastened to the rear cover plate 10 by a snap fastener. The high-voltage socket terminal 21 is cylindrical. There is a hole at the head for inserting into the high-voltage pin terminal 20. There are three annular grooves on the head hole for installing the contact spring 24. There is a hole at the tail for installing and crimping the high-voltage cable. After the high-voltage socket terminal 21 crimps the cable, it is inserted into the second insulating mounting plate 12, and the rear cover plate 10 is fastened to fix it.

[0043] Both the low-voltage socket terminal 23 and the grounding socket terminal 162 are cylindrical, with a hole at the head and a hole at the tail: the head hole is used to install the contact spring 24 and the spring retainer 26, and the tail hole is used to crimp the cable; the barbed structure on the outer circle of both ensures that they will not come out after being installed on the second insulating mounting plate 12.

[0044] During use, when the first insulating mounting plate 11 and the second insulating mounting plate 12 begin to align, the high-voltage pin terminal 20 and the high-voltage socket terminal 21, and the low-voltage pin terminal 22 and the low-voltage socket terminal 23 will be accurately aligned under the guidance of the guide component 15. As the alignment deepens, the insulating anti-touch cover 251 on the head of the high-voltage pin terminal 20 will first contact the high-voltage socket terminal 21. This insulating anti-touch cover 251 can effectively prevent personnel from accidentally touching the high-voltage parts and ensure operational safety.

[0045] When the high-voltage pin terminal 20 is inserted into the head hole of the high-voltage socket terminal 21, the contact spring 24 installed in the annular groove on the head hole of the high-voltage socket terminal 21 will make close contact with the high-voltage pin terminal 20. The contact spring 24 has good elasticity and conductivity, and can provide stable contact pressure to ensure reliable connection of high-voltage circuit. This solves the problem of the low number of insertion and removal cycles of traditional connectors and the easy occurrence of momentary disconnection during vibration, and greatly improves the stability of signal transmission in new energy vehicles.

[0046] At the same time, the low-voltage pin terminal 22 will also be inserted into the low-voltage socket terminal 23. The contact spring 24 inside the low-voltage socket terminal 23 will also form a stable electrical connection with the low-voltage pin terminal 22. The use of the contact spring 24 makes the transmission of low-voltage signals more reliable, further ensuring the stability of the entire charging system.

[0047] During the docking process, the temperature detection harness 252 installed in the small hole in the center of the high-voltage pin terminal 20 will monitor the temperature of the high-voltage pin terminal 20 in real time. When the temperature is abnormal, the temperature detection harness 252 can transmit the signal to the control system in a timely manner so that corresponding measures can be taken to prevent safety hazards caused by excessive temperature.

[0048] When the first insulating mounting plate 11 and the second insulating mounting plate 12 are fully inserted, the O-rings 28 play an important sealing role. The O-rings 28 in the outer circular grooves of the insertion ends of the first insulating mounting plate 11 and the second insulating mounting plate 12 can prevent dust and other impurities from entering the contact body and ensure the stability of the electrical connection. The O-rings 28 under the rectangular flange can ensure the seal between the first insulating mounting plate 11 and the mounting aluminum plate 13 and prevent external moisture or liquid from entering. The O-rings 28 on the high-voltage pin terminal 20 ensure its sealing performance with the first insulating mounting plate 11.

[0049] In addition, the spring retainer 26 at the head of the high-voltage socket terminal 21 and the low-voltage socket terminal 23 can firmly fix the contact spring 24 inside the terminal, ensuring that the contact spring 24 will not shift or fall off during long-term use, further improving the reliability of the connector. The grounding component 16 will achieve grounding in advance during the mating process, providing safety assurance for the entire charging system.

[0050] When the connector needs to be disconnected, under the action of external force, the first insulating mounting plate 11 and the second insulating mounting plate 12 gradually separate, and the high-voltage pin terminal 20 and the high-voltage socket terminal 21, and the low-voltage pin terminal 22 and the low-voltage socket terminal 23 are smoothly disengaged. The contact spring 24 returns to its original shape, preparing for the next connection. Throughout the entire insertion and removal process, the elastic contact of the contact spring 24 and the synergistic effect of the various sealing structures enable this pin-type pluggable charging connector to work stably in various complex environments.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
