Quick-change type electric automobile charging base female terminal

Abstract

The invention discloses a quick-change type electric automobile charging base female terminal. The quick-change type electric automobile charging base female terminal comprises a terminal crimping part, a rotation stopping part, a female end sleeve shell, a fixed sleeve and a contact spring piece; a wire core is inserted into a wire pressing hole, and then by extruding the terminal crimping part,the wire pressing hole is deformed to tightly clamp the wire core; the assembly mode is simple and rapid, and the connection is firm. When a male terminal is plugged, the contact spring piece is reasonably arranged, so that the male terminal can be guided to be inserted into the female end sleeve shell quickly and accurately; in addition, the contact spring piece is soft, so that the gap between the male terminal and the female end sleeve shell can be fully filled, the male terminal can be tightly pressed, and the tightness of the matching between the male terminal and the female end sleeve shell can be effectively improved; meanwhile, the abrasion-resistant effect of the contact spring piece is high, so that the number of times of plugging can be effectively increased, and the service life is prolonged; and in replacement, only the male terminal needs to be pulled out, and then the rotation stopping part is unscrewed, and at the moment, the terminal crimping part can be screwed and extruded, so that a sleeve connecting cylinder and the female end sleeve shell 3 are separated from each other, and the whole replacement process is convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of a car charging stand, in particular to a quick-change electric car charging stand female terminal applied to an electric car. Background technique [0002] Due to the wide range of energy sources, quiet running, and no pollution emissions, electric vehicles have attracted more and more attention from various automobile manufacturers, and they have launched household electric vehicles one after another. [0003] There are a variety of charging stations on the market that are used to adapt to household electric vehicles, each of which has a different design concept, and strives to meet the requirements of different users. However, although the female terminals of these charging stations can roughly meet the plug-in requirements, the design is not ingenious, and the assembly with the male terminals is not tight enough, which affects the stability of the electrical connection. It is easy to cause damage due ...

AI Technical Summary

Problems solved by technology

However, although the female terminals of these charging stations can roughly meet the plug-in requirements, the design is not ingenious, and the assembly with the male terminals is not tight enough, which affects the stability of the electrical connection. It is easy to cause damage due to wear and tear. At this time, it is necessary to replace a new female terminal. The existing female terminal has a complicated structure and a complicated replacement process, which is time-consuming and laborious, which brings inconvenience to use and daily maintenance.

In addition, after long-term use, it is easy for foreign matter such as dust to enter the female terminal. At this time, the structure that is not conducive to removing foreign matter will bring trouble to the cleaning process. If it is not cleaned in time, it will be difficult to ensure the electrical contact effect and affect job stability
