The tail end of the charging gun head 1 is provided with the same quick-change socket 11. The charging cable includes a cable 5 and a quick-change connector 2 provided at one end of the cable 5. The quick-change socket 11 and the quick-change connector 2 are detachably connected, so that the charging cable can be quickly matched with different charging gun heads 1.

[0027] A terminal assembly is provided in the quick-change socket 11, a mating terminal 6 is provided in the terminal assembly, and a fixed terminal 8 is provided in the quick-change connector 2. The quick-change socket 11 and the quick-change connector 2 are electrically connected by plugging the mating terminal 6 into one end of the fixed terminal 8, and the other end of the fixed terminal 8 is electrically connected to one end of the cable 5.

[0028] Among the various existing automobile charging and discharging devices, the charging gun head 1 of most products is fixedly connected to the cable 5, and the charging gun head 1 cannot be disassembled and replaced, and the cable 5 cannot be quickly replaced with the charging gun head 1, resulting in the inability to meet the charging and plugging requirements of different vehicle interfaces. A new set of cables 5 and charging guns need to be replaced and developed to meet the charging and plugging requirements of different vehicle interfaces. A wide variety of products need to be developed, the development time is too long, and the cost is too high.

[0029] The charging cable and the charging gun head 1 of the present application are split structures. The charging cable includes a cable 5 and a quick-change connector 2 arranged at one end of the cable 5. The tail end of the charging gun head 1 is provided with the same quick-change socket 11. The quick-change socket 11 and the quick-change connector 2 are detachably connected, so that the charging cable can be quickly matched and connected to different charging gun heads 1 to meet the interface plug-in charging requirements of different vehicles, and has strong applicability.

[0030] In some embodiments, the terminal assembly further includes a mounting bracket 7 for fixing the mating terminal 6 , and the mounting bracket 7 is detachably connected to the tail end of the charging gun head 1 .

[0031] The mounting bracket 7 can firmly fix the mating terminal 6 to meet the plug-in requirements of the fixed terminal 8. The mounting bracket 7 is detachably connected to the tail end of the charging gun head 1. If the mounting bracket 7 is damaged or the mating terminal 6 is damaged, it is easy to disassemble and replace, saving replacement costs and time.

[0032] In some embodiments, the fixed terminal 8 includes a plug-in end 81 and a wiring terminal 82, the wiring terminal 82 is connected to one end of the cable 5, and the plug-in end 81 is plugged into the mating terminal 6. The quick-change connector 2 also includes a fixed bracket 21, and a through terminal accommodating cavity 211 is provided in the fixed bracket 21. The plug-in end 81 and the mating terminal 6 are plugged into the terminal accommodating cavity 211.

[0033] The plug-in end 81 and the mating terminal 6 are plugged into each other in the terminal accommodating cavity 211. The fixed bracket 21 can protect the plug-in position of the plug-in end 81 and the mating terminal 6. The plug-in position is separated from the external environment and will not be separated by external force, thereby ensuring the transmission and safety of electricity.

[0034] In some embodiments, the quick-change connector 2 further includes a housing 22 that is sleeved around at least a portion of the outer periphery of the fixing bracket 21 . Inserting and removing the housing 22 can drive the fixing bracket 21 and the fixing terminal 8 to be separated from or inserted into the mating terminal 6 .

[0035] The shell 22 can protect the fixed bracket 21 and the terminals inside the fixed bracket 21, and the appearance is more beautiful. When the fixed terminal 8 and the mating terminal 6 need to be disconnected or connected, the shell 22 can be pulled out and plugged in more quickly.

[0036] In some embodiments, the quick-change connector 2 further includes a cable sheath 23 that is engaged with the housing 22 . The cable sheath 23 and the housing 22 are both provided with a coaxial through hole, and the other end of the cable 5 passes through the through hole.

The other end of the cable 5 can pass through the hole to connect to different electrical components to meet different electricity usage scenarios and uses.

[0038] In some embodiments, the free end of the other end of the cable 5 is connected to a plug or a socket or other charging gun head or a charging pile.

[0039] The free end of the other end of the cable 5 is connected to a plug or socket or other charging gun head or charging pile to meet different charging and discharging requirements. The charging gun with a quick-adaptation charging interface designed in this invention can realize different types of variant quick-change forms to meet the different needs of various users and meet market diversity.

[0040] In some embodiments, the cable 5 includes a conductor core, and the terminal 82 is electrically connected to the conductor core.

[0041] The terminal 82 is electrically connected to the conductive core to achieve power transmission.

[0042] In some embodiments, the connection between the terminal 82 and the conductor core is achieved by welding or crimping.

[0043] Crimping involves assembling the terminal 82 and the conductor, then using a crimping machine to press the two together. The advantage of crimping is its high production capacity. Automatic crimping machines allow for rapid, high-quality production.

[0044] Welding generally uses resistance welding, friction welding, ultrasonic welding and arc welding. Resistance welding refers to a method of welding that uses a strong current to pass through the contact point between the electrode and the workpiece, generating heat due to the contact resistance.

[0045] Friction welding refers to a method of welding that uses the heat generated by friction between the contact surfaces of the workpieces as a heat source to cause the workpieces to undergo plastic deformation under pressure.

[0046] Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects rub against each other to form a fusion between the molecular layers.

[0047] Arc welding refers to the use of electric arc as a heat source and the physical phenomenon of air discharge to convert electrical energy into the thermal energy and mechanical energy required for welding, thereby achieving the purpose of connecting metals. The main methods include arc welding, submerged arc welding, gas shielded welding, etc.

[0048] In some embodiments, a card slot is provided in the housing 22 , and the cable sheath 23 is provided with a card connection portion that is engaged with the card slot.

[0049] The engagement of the engaging portion with the engaging slot can securely connect the cable sheath 23 and the housing 22 together, and the cable sheath 23 can better protect the cable 5 .

[0050] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
