## Title
Heavy current female connector

## Abstract

A new fastening heavy current female connector comprising a main body and terminal assemblies. The main body includes separated terminal grooves provided on both of its upper and lower arms and a terminal plugging opening which is a recess in the main body and located between the upper and lower grooves. Each terminal assembly includes two terminals inserted into one of the separated terminal grooves. Each terminal includes a bending portion located between its plugging and non-plugging ends. The new heavy current female connector adds bending portions to the terminals of a common connector. The terminal is bended at its bending portion, enabling it to be elastic and possess a certain degree of tolerability to plugging deflection. Specifically, when the present female connector and a male connector are plugged, stable contacting of electric conductors is ensured.

## Background
TECHNICAL FIELD
The present application relates to the field of connector, particularly to a new heavy current female connector.
BACKGROUND
Under the circumstance of heavy current, security becomes the premier standard for appraising the quality of connector products. As an important aspect of connector security, the terminals' anti-deflection ability plays a leading role in ensuring the security and durability of connector.
Nowadays, one of the defects of the heavy current connector in prior art is its low adaptability to plugging deflection, i.e. its tolerance to plugging deflection, which may result in bad connection and hence various electrical risks. Furthermore, these connectors are short of plugging convenience and connecting reliability, failing to enhance the connector's security.
SUMMARY
To solve the above mentioned technical problems, the present application provides a new heavy current female connector, which possesses a certain degree of tolerability to plugging deflection and supports hot plugging, greatly enhancing the connector's security and practicability under the circumstance of heavy current conduction.
To be specific, the present application provides a new heavy current female connector comprising a main body and terminal assemblies. The main body includes separated terminal grooves provided on both of its upper and lower arms and a terminal plugging opening which is a recess in the main body and located between the upper and lower arms. Each terminal assembly includes two terminals, each inserted into one of the separated terminal grooves. Each terminal includes a bending portion located between its plugging and non-plugging ends, where the terminal bends.
In a further optimized technical solution, the bending portion is positioned in the middle portion of the terminal.
In a further optimized technical solution, the terminal plugging opening is located in the middle portion of the main body.
In a further optimized technical solution, each terminal includes a lower contacting point specifically located between the bending portions and the non-plugging end.
In a further optimized technical solution, each terminal includes a higher contacting point specifically located between the lowering contacting point and the non-plugging end. Preferably, there are three lower contacting points on each terminal, and at least one lower contacting point will conductively contact the conductive portion of a respective male connector.
In a further optimized technical solution, each terminal includes two side protrusions provided on both sides of the same. When the terminal is inserted into a groove, the side protrusions bear against the inner sides of the groove.
In a further optimized technical solution, the side protrusions are located near the bending portion.
In a further optimized technical solution, each terminal assembly includes an insulation cap fitted at the non-plugging end of the terminal.
In a further optimized technical solution, the insulation cap is fitted to one or two of the terminals of each terminal assembly.
In a further optimized technical solution, the main body includes fastening holes located at two sides of the main body.
Following beneficial effects are achieved by the present application thanks to employment of the above technical solutions. Compared with disclosed technical solutions in the art, the present new heavy current female connector provides a common connector with bending portions added to its terminals. The terminal is bended at its bending portion, making it elastic and therefore possess a certain degree of tolerability to plugging deflection. Specifically, when the present female connector and a male connector are plugged to each other, if the male connector is slantly plugged, the contacting points of the two terminals of the female connector will become inclined as the slant of the male connector so as to guarantee constant spacing of the terminals, thus ensuring stable contacting of the electric conductors.
The terminal plugging opening is configured to symmetrically receive the lower and contacting points, enabling hot plugging of the present female connector. Specifically, there are three lower contacting points on each terminal, and at least one lower contacting point conductively contacts the conductive portion of a respective male terminal.
There are insulation caps assembled at the terminal's non-plugging ends and extending into the separated terminal grooves, which guarantee the correct postures of the terminals as they fit into the main body to avoid pressing between terminals that gives rise to short circuit or deflection in side directions.
When each terminal assembly is inserted into a separated terminal groove, the side protrusions bear against the inner sides of the groove so that the terminal is anchored in the groove, preventing the terminal from extending out of the plugging opening but allowing it to move in the opposite direction.
The main body is provided with fastening holes at its two sides, which cooperate with threaded bolts to strengthen the connection of the male and female connectors.
