[0027] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0028] A first aspect of this embodiment provides a charging terminal, such as Figures 1 to 7 As shown, it includes a wiring portion 1, a plug-in portion 2 and a fixing portion 3 connecting the wiring portion 1 and the plug-in portion 2, the plug-in portion 2 is a plurality of elastic sheets 201 arranged at circumferential intervals, each of the elastic sheets 201 is provided with a bending section 202, the fixing portion 3 is provided with a slot 301 matching the bending section 202, the bending section 202 is inserted into the slot 301 to connect the elastic sheet 201 with the fixing portion 3.

[0029] In this embodiment, the bending section 202 is arranged at the top of the elastic sheet 201, the axis of the bending section 202 is arranged perpendicular to the axis of the elastic sheet 201, and the bending section 202 and the elastic sheet 201 are integrally formed, so that the connection points of welding or crimping can be reduced, the stability and integrity of the connection between the elastic sheet 201 and the bending section 202 can be ensured, and the conductive safety and reliability of the device can be improved. The number of slots 301 and elastic sheets 201 is arranged one by one, and the slots 301 are opened along the radial direction of the fixing part 3, so that the elastic sheet 201 can be prevented from being separated from the fixing part 3 along the axial direction of the terminal. In actual use, the bending section 202 is horizontally inserted into the slot 301, the elastic sheet 201 is connected to the fixing part 3, and the assembly of the terminal is completed. When the elastic sheet 201 needs to be replaced, the bending section 202 is pulled out from the slot 301, and a new elastic sheet 201 is inserted into the slot 301 to complete the replacement.

[0030] Through the above technical solution, by setting a slot 301 on the fixing part 3, setting a bending section 202 on the elastic sheet 201, inserting the bending section 202 into the slot 301 to connect the elastic sheet 201 with the fixing part 3, the charging terminal is assembled; when the elastic sheet 201 needs to be replaced, it is only necessary to pull the bending section 202 out of the slot 301 and replace it with a new elastic sheet 201, thereby realizing the rapid installation and removal of the elastic sheet 201, which is simple to operate and improves work efficiency. The problem that the elastic sheet 201 on the female terminal cannot be replaced after being worn, resulting in a large maintenance cost and reduced economic benefits is solved.

[0031] In some embodiments, reference Figures 5 to 7 The charging terminal also includes a locking member 4. The two side surfaces of the slot 301 are oppositely provided with penetrating fixing holes 302. The bending section 202 is provided with a through hole. The locking member 4 sequentially penetrates the fixing hole 302 and the through hole to lock and fix the elastic sheet 201 to the slot 301. In this embodiment, the locking member 4 can be a screw. The screw has a low screw-in torque and high locking performance. It is easy to install and has a fast installation speed. It can complete the tightening and anti-loosening effects by itself, thereby improving work efficiency. The setting of the locking member 4 improves the connection strength between the elastic sheet 201 and the fixing part 3, avoids the separation of the elastic sheet 201 and the fixing part 3, and further improves the reliability of the device.

[0032] In some embodiments, the fixing hole 302 is a threaded hole located on the side close to the wiring portion 1. In this way, the locking member 4 can lock the elastic sheet 201 on the fixing portion 3 through threaded connection, achieving a more stable connection and preventing the elastic sheet 201 from loosening or falling off during connection.

[0033] In some embodiments, reference Figure 3 and Figure 4An inner groove 203 is formed on two opposite sides of the elastic sheet 201 along the length direction of the elastic sheet 201, and a clamping section 204 is formed between the two inner grooves 203. The two inner grooves 203 are arranged opposite to each other, so that the elastic sheet 201 can be clamped by a tool for installation or removal, which is convenient for operation. The arrangement of the clamping section 204 improves the clamping stability and operation efficiency.

[0034] In some embodiments, reference Figure 2 , Figure 5 and Figure 6 The outer circumference of the fixing part 3 is provided with a receiving groove 303 along the axial direction of the elastic sheet 201. The receiving groove 303 corresponds to the position of the slot 301 and is connected to the slot 301. At least part of the elastic sheet 201 is placed in the receiving groove 303, and the outer surface of the elastic sheet 201 is flush with the outer circumference of the fixing part 3. In this way, the outer circumference of the terminal can be ensured to be smooth and avoid interference during installation. In addition, the radial size of the terminal is reduced, which reduces the occupied space and facilitates installation.

[0035] In some embodiments, reference Figure 3 , Figure 4 , Figure 6 and Figure 7 A fixing ring 5 is sleeved on the outer periphery of the elastic sheet 201 near the bending section 202, and the fixing ring 5 is connected to the outer periphery of the elastic sheet 201 by interference fit. The fixing ring 5 provides a continuous retraction force for the elastic sheet 201 to avoid deformation of the elastic sheet 201. Moreover, the fixing ring 5 is connected to the outer periphery of the elastic sheet 201 by interference fit, which has a simple structure and improves assembly efficiency. At the same time, it can also prevent the fixing ring 5 from falling off, thereby improving the stability of the device. Furthermore, part of the fixing ring 5 extends to the fixing portion 3 and is detachably connected to the fixing portion 3. In this way, the elastic sheet 201 can be further fixed, thereby improving the reliability of the device.

[0036] In some embodiments, reference Figures 2 to 4 , a guide portion 205 is provided at the free end of the bending section 202, and the cross-sectional area of ​​the guide portion 205 gradually decreases from the bending section 202 to the end. The guide portion 205 is provided on both sides of the width of the bending section 202, so that the width of the free end is smaller than the width of the slot 301, and has a certain guiding property. When the elastic sheet 201 is inserted into the slot 301, under the guiding effect of the guide portion 205, the bending section 202 can be inserted into the slot 301 without deliberate alignment when inserted into the slot 301, which is simple to operate and can also avoid errors and damage to parts. At the same time, the cross-sectional area of ​​the free end gradually decreases, which is equivalent to reducing the thickness of the bending section 202, making the operation of the free end easier when inserted into the slot 301, further improving the convenience of inserting the elastic sheet 201 into the slot 301, and improving the work efficiency of component assembly.

[0037] In some embodiments, a coating is provided on the surface of the bending section 202. In this embodiment, a layer of metal material is coated on the surface of the bending section 202 to form a protective layer with extremely low chemical reactivity, thereby preventing the bending section 202 from experiencing a decrease in electrical and mechanical properties due to multiple plugging and unplugging and environmental influences, protecting the bending section 202, extending the service life of the elastic sheet 201, and improving the quality of circuit contact to ensure reliable transmission of electrical signals. In this embodiment, a tin-plated, silver-plated or nickel-plated layer can be selected, which has high conductivity, can better play a conductive role, and has corrosion resistance and wear resistance, extending its service life.

[0038] The present disclosure also provides a charging stand, comprising the charging terminal as described above.
