Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it is to be understood that the terms "top," "bottom," and the like, as used herein, refer to an orientation or positional relationship based on that shown in the drawings for convenience in describing the present application and simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be taken as limiting the present application.

The overcurrent capacity of a conductive terminal is determined by its own resistance, and generally speaking, the smaller the resistance, the larger the overcurrent capacity. The size of the resistor is related to the volume of the conductive terminal in addition to the conductivity of the conductive terminal material, and when the length of the resistor is equal, the larger the cross-sectional area of the conductive terminal is (the wider and the higher the conductive terminal is), the smaller the resistor is, and the larger the overcurrent capacity is.

Referring to fig. 10, in order to satisfy the function of forward and backward insertion, 24 symmetrical conductive terminals are arranged on the upper, lower, left and right sides of the female connector base, which causes congestion between the conductive terminals, especially the power terminals (a4, a9, B4, B9) having the charging function, because other terminals are arranged on the upper, lower, and both sides, and the manufacturing process and other factors are also adopted, the width and thickness of the power terminals are limited, so the overcurrent capacity is limited; even if the material of the conductive terminal itself is improved, the conductive terminal manufactured by the high-conductivity copper material on the market at present cannot meet the heavy current overload of more than 10A, thereby further limiting the improvement of the charging power.

In order to solve the above problem, an embodiment of the present application provides a female connector housing 10, including: a plurality of conductive terminals 110, wherein the conductive terminals 110 include power terminals 115, and two power terminals 115 oppositely arranged along the thickness direction of the female connector housing 10 form a power terminal group 111; specifically, referring to fig. 10, the a4 power terminal 115 and the B9 power terminal 115 are oppositely disposed to form one power terminal group 111, and the a9 power terminal 115 and the B4 power terminal 115 are oppositely disposed to form one power terminal group 111, i.e., one connector female housing 10 may form two power terminal groups 111.
