Charging gun and charging socket matched with same

Abstract

The invention provides a charging gun which comprises a shell, the shell is provided with a bayonet socket, a main cavity and a cable chamber, the shell is further provided with an unlocking swing rod, one end, facing the front end of the shell, of the unlocking swing rod is provided with a lock hook, the other end of the unlocking swing rod is provided with a button, the bayonet socket is provided with two inserting columns which are parallel to each other and arranged in a spaced mode, and the main cavity is provided with an opening. The plugging column is provided with a locking section, a rotation section and a wiring driving section, the section of the locking section is polygonal and is spirally twisted towards the circumferential direction of the plugging column, meanwhile, the profile of the section of one side, close to the front end of the locking section, of the locking section is reduced, the rotation section is in running fit with the plugging seat, and the wiring driving section is located in the main cavity; the outer wall of the wiring driving section is provided with gear teeth, and the rear end face is provided with a first wiring hole; a rack meshed with the two inserting columns is arranged between the gear teeth of the wiring driving sections of the two inserting columns, and the rack is matched with the unlocking swing rod. The connector has the advantages that connection is reliable, abrasion and plugging resistance are effectively reduced, and meanwhile connection reliability is guaranteed.

Description

technical field [0001] The invention relates to the field of charging guns, in particular to a charging gun and a charging socket adapted thereto. Background technique [0002] With the popularity of new energy vehicles, their charging often needs to be charged through the adaptation of the charging gun and the charging socket of the body. At present, the charging time of new energy vehicles is often flawed, so they are generally innovated on batteries and charging piles to improve the This improves the charging efficiency, but the charging gun and the charging socket of the body are in a state of frequent plugging and unplugging. The traditional plugging method adopts the plugging and matching between the male and female heads, so as to meet the reliability of the electrical connection. However, although the tight plug fit ensures the effective current carrying area between the conductors, it will lead to an increase in the plug resistance. For some users who use household ...

[0002] With the popularity of new energy vehicles, their charging often needs to be charged through the adaptation of the charging gun and the charging socket of the body. At present, the charging time of new energy vehicles is often Therefore, innovations are generally made on batteries and charging piles to improve charging efficiency. However, both the charging gun and the charging socket of the car body are in a state of frequent plugging and unplugging. The traditional plugging method uses male and female The plug-in fit between the heads is tight, so as to meet the reliability of the electrical connection, but too tight plug-in fit ensures the effective current carrying area between the conductors, but it will lead to an increase in plug-in resistance. For users of charging piles, the power charged every night is often difficult to compare with that of fast charging stations. Therefore, plugging and unplugging is performed almost every day. The effective electrical contact area decreases, which in turn causes the current increase in the local contact part to cause heat generation, ablation, and fusion welding, which is prone to safety hazards, which also leads to the difficulty of plugging and unplugging in the early stage and the problem of reduced reliability in the later stage; For some public charging piles, due to the high frequency of charging, the number of plugging and unplugging also increases, which further aggravates the wear and tear
