[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0027] This application discloses an integrated charging gun. (Refer to...) Figure 1 and Figure 2 The integrated charging gun includes a housing 1, a gun head 2, and a tail sleeve 3. The gun head 2 and the tail sleeve 3 are respectively snapped onto both ends of the housing 1. Sealing washers 4, made of rubber, are provided on both the gun head 2 and the tail sleeve 3 of the housing 1. The gun head 2 and the tail sleeve 3 press the sealing washers 4 firmly onto the housing 1. This connection method avoids the loosening and rusting problems associated with screw fixing, ensuring the internal sealing of the charging gun. This is because the snap-fit structure is more stable and not affected by rust, maintaining a good sealing state for a long time.
[0028] Reference Figure 2 The gun head 2 includes a head body 21, several head connecting rods 22, and several head protrusions 23. The head body 21 is the main body of the gun head 2 and can be made of insulating materials such as plastic. One end of each of the head connecting rods 22 is integrally formed on the end of the head body 21 near the housing 1, and they are arranged sequentially along the circumference of the head body 21. The head connecting rods 22 are usually long strips, and their material can be the same as that of the head body 21. In some special cases, they can also be metal rods wrapped with an insulating layer to ensure their strength and conductivity.
[0029] The number of head protrusions 23 is the same as the number of head connecting rods 22. Each head protrusion 23 corresponds to one head connecting rod 22. The head protrusion 23 is integrally formed on the end of the head connecting rod 22 near the housing 1 and is located on the outside of the head connecting rod 22. The head protrusion 23 is also mainly made of plastic.
[0030] The inner wall of the housing 1 near the head body 21 has a head locking groove 11 for the head protrusion 23 to engage. The head body 21 is engaged with the housing 1 via the head connecting rod 22 and the head protrusion 23. During installation, the head connecting rod 22 is inserted into the housing 1, causing the head protrusion 23 to engage in the head locking groove 11, thereby achieving a stable connection between the gun head 2 and the housing 1. This engaging method is simple, convenient, and not easy to loosen, effectively improving the sealing performance of the charging gun.
[0031] Several guide and limiting plate assemblies 12 are integrally formed on the inner wall of the housing 1. A gap is formed between each guide and limiting plate assembly 12 for the head connecting rod 22 and the head protrusion 23 to pass through. The head slot 11 is located within the gap, and the guide and limiting plate assembly 12 can abut against the side wall of the head connecting rod 22. The guide and limiting plate assembly 12 is generally composed of two parallel thin plates, which can be made of plastic with a smooth surface to reduce friction with the head connecting rod 22. Its function is to guide the head connecting rod 22 during insertion, ensuring that the head protrusion 23 accurately engages with the head slot 11, while simultaneously limiting the position of the head connecting rod 22 to prevent it from shaking, further enhancing the stability of the connection between the gun head 2 and the housing 1.
[0032] The integrated charging gun also includes a cable clamping plate 13, which is installed at one end of the housing 1 near the head body 21. A cable clamping hook 131 is integrally formed on the cable clamping plate 13, located between the cable clamping plate 13 and the housing 1. The head connecting rod 22 is inserted between the cable clamping plate 13 and the housing 1, and a head latching hole 24 is provided on the head connecting rod 22 for the cable clamping hook 131 to engage. The cable clamping hook 131 can be arc-shaped and has a certain degree of elasticity. During installation, the head connecting rod 22 is inserted into the housing 1, causing the head protrusion 23 to engage with the head latching groove 11. At this time, the cable clamping hook 131 is engaged in the head latching hole 24, thus restricting the head connecting rod 22 between the cable clamping plate 13 and the housing 1.
[0033] Reference Figure 2 and Figure 3 The tail sleeve 3 includes a tail body 31, a tail link 32, several tail links 33 and several tail protrusions 34. The tail link 32 is integrally formed on the end wall of the tail body 31 near the housing 1. Several clearance grooves 321 are provided on the tail link 32. Each clearance groove 321 is provided with a tail link 33. One end of the tail link 33 is integrally formed with the inner wall of the clearance groove 321 near the housing 1, and the other end has a gap with the inner wall of the clearance groove 321 near the tail body 31.
[0034] The tail body 31 is the main part of the tail sleeve 3. The tail link 32 is a ring-shaped structure and is made of the same material as the tail body 31. The tail protrusion 34 is connected to the end of the tail link 33 near the housing 1 and is located on the outside of the tail link 33. The inner side wall of the housing 1 has a tail slot 14 for the tail protrusion 34 to be engaged. During installation, the tail link 33 is inserted into the housing 1, so that the tail protrusion 34 is engaged with the tail slot 14, thereby achieving the engagement between the tail sleeve 3 and the housing 1.
[0035] Reference Figure 2 and Figure 4A clamping block 35 is integrally formed at one end of the tail connecting rod 33 near the tail body 31. The clamping block 35 is located inside the tail connecting rod 33 to clamp the cable. An inclined guide surface 351 is provided at the end of the clamping block 35 away from the housing 1 to facilitate cable insertion. Two clamping ramps 352 are provided on the end wall of each clamping block 35 away from the tail connecting rod 33. The two clamping ramps 352 are symmetrically arranged in their inclined directions, forming a clamping edge 353 between them. This structure allows the clamping block 35 to better conform to the cable, enhancing the clamping effect.
[0036] The implementation principle of an integrated charging gun according to an embodiment of this application is as follows: During installation, the head connecting rod 22 is inserted between the cable clamping plate 13 and the housing 1. At this time, the head protrusion 23 is engaged with the head slot 11, and the cable clamping hook 131 is engaged with the head slot 24. The tail connecting rod 33 is inserted into the housing 1, and the tail protrusion 34 is engaged with the tail slot 14. At the same time, multiple clamping blocks 35 clamp the cable. Through the snap-fit connection between the gun head 2 and the tail sheath 3 and the housing 1, the loosening and rusting problems caused by traditional screw fixing are avoided, effectively ensuring the sealing of the charging gun during use.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
