Description

Line ball structure and be equipped with its rifle that charges Technical Field The application relates to the technical field of charging equipment, in particular to a wire pressing structure and a charging gun with the same. Background The charging gun is mainly used as a key component in a new energy automobile charging system and is used for connecting an electric automobile with a charging pile to provide electric energy for an automobile battery. The charging gun is connected with the charging pile through the cable, so that the assembly reliability of the cable relative to the charging gun is extremely important. In the related art, an external thread is usually arranged on a gun shell of the charging gun, a wire pressing sleeve is connected to a cable in a sleeved mode, an internal thread is arranged on a wire clamp main body, and the wire clamp main body penetrates through the cable to be in threaded connection with the external thread on the cavity, so that the locking and fixing functions are achieved. However, in order to meet the threaded connection between the wire clamp main body and the gun shell, the wire clamp main body and the gun shell are required to be pre-threaded, the wall thickness of the wire clamp main body and the gun shell is inevitably thinner, and the end part of the wire clamp main body and the gun shell forms a step shape, so that uneven stress is caused, stress concentration is easily caused, and the strength of the gun shell is further reduced. Disclosure of utility model Based on the above, it is necessary to provide a wire pressing structure, which is adapted to the gun housing of the charging gun by utilizing the special-shaped arrangement thereon, so that the reduction of the wall thickness and the stepped end caused by the prefabricated threads are eliminated, the uneven stress is relieved, the assembly strength and the reliability are improved, and the connection reliability with the cable is improved. The wire pressing structure is used for being connected with a gun shell of a charging gun and comprises a first wire pressing shell and a second wire pressing shell, wherein the first wire pressing shell comprises a sleeve part and a wire pressing part arranged at one end part of the sleeve part, the sleeve part is provided with a barrel cavity penetrating along the axial direction of the sleeve part, the second wire pressing shell is detachably connected with the first wire pressing shell and is surrounded with the wire pressing part to form a wire pressing cavity, the wire pressing cavity is communicated with the barrel cavity, and at least the projection outline of the sleeve part along the axial direction of the barrel cavity is in special-shaped arrangement. It can be understood that the sleeve part can be directly sleeved outside the cable, so that the cable can be stored and restrained, and then the assembly of the wire pressing part and the second wire pressing shell is matched, so that the assembly area of the wire pressing structure and the cable is increased, and the connection reliability is improved. Because at least sleeve portion dysmorphism sets up, has not only increased the area of contact of sleeve portion with the rifle shell, and utilizes the cooperation of dysmorphism can also play spacing effect to the rotation of sleeve portion relative rifle shell around a section of thick bamboo chamber axis, and then improves the connection reliability of this line ball structure with the rifle shell. Meanwhile, due to the arrangement, the gun shell and the sleeve part are enabled to be matched without a threaded structure, the wall thickness of the gun shell is not affected, the stepped end part is not existed, the problem that stress of the gun shell is uneven due to the stepped structure is solved, the structural strength of the gun shell is improved, and the assembly strength and the reliability are improved. In some embodiments, the sleeve part comprises a cylinder surrounding a cylinder cavity and a special-shaped body surrounding the outer periphery of the cylinder, wherein the special-shaped body is provided with special-shaped protrusions protruding outwards along the radial direction of the cylinder cavity. In some of these embodiments, the sleeve portion is integrally formed with the wire pressing portion, and the cylinder and the profile body are integrally formed. In some embodiments, the first wire pressing shell is provided with an inserting groove at the outer peripheral side of the first wire pressing shell, a notch of the inserting groove is arranged along the axial direction of the barrel cavity towards one side far away from the second wire pressing shell, and the inserting groove is used for inserting and matching the end part of the gun shell. In some embodiments, a plurality of pressing protrusions are arranged at intervals on the inner side of the pressing portion and/or the inner side of the second pressing shell in a protruding mode
