It will be understood that terms, such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
Fig. 1 is a female terminal structure capable of reducing contact resistance of a terminal according to the present invention, which includes a female terminal body 1, wherein a contact 3 for reducing contact resistance of a male terminal is provided on the female terminal body 1, and the contact 3 is configured to form multi-point contact when a male terminal 2 and a female terminal are connected.
In the above technical solution, the contact element 3 and the male and female terminals form multi-point contact, which is equivalent to parallel connection of other resistors, and the matching mode can reduce contact impedance to reduce heat generation.
In the above technical solution, the female terminal body 1 is provided with a cavity 101 inside; the contact 3 includes:
an elastic member 301 located in the cavity 101 of the female terminal body 1;
an electronic pin 302 having one end in contact with the elastic member 301 and located in the cavity 101 of the female terminal body 1 and the other end extending out of the cavity 101 of the female terminal body 1 and in contact with the male terminal 2 to compress the elastic member 301 when the male and female terminals are connected; wherein, the electronic pin 302 forms multi-point contact with the inner surface of the cavity 101, the male terminal 2 and the elastic member 301 to reduce the contact resistance of the male and female terminals.
By adopting the technical scheme, when the female terminal body 1 is matched with the male terminal, one end of the electronic pin 302 is contacted with the elastic piece 301, the other end is contacted with the top of the male terminal, the elastic piece 301 is extruded by the electronic pin, and after the male terminal is matched, other resistors are connected in parallel, so that the contact impedance of the male terminal and the female terminal is reduced, and the heating is reduced. In the above technical solution, the length of the compressed spring and the length of the electronic pin need to ensure that the electronic plug-in unit extending out of the cavity forms good contact with the male terminal.
In the above technical solution, the elastic member 301 is spring steel, and a radial cross-sectional area of the spring steel is smaller than a radial cross-sectional area of the cavity; the cross section of the elastic piece is any one of a circle, a square, a triangle and a polygon. In this way, the spring steel is able to effectively achieve compression of the electronic card.
In the above technical solution, the electronic PIN 302 is a PIN; the axial section of the electronic contact pin is any one of T-shaped, conical, triangular and square structures, and one end of the electronic contact pin in the cavity is matched with the structure of the cavity. In this way, the electronic pin is effectively limited in the female terminal, and compression of the electronic pin and the elastic piece can be conveniently realized.

In this way, the contact friction between the electronic pin 302 and the female terminal body 1 is made smaller, and the sliding effect is better in the male-female terminal contact process.
In the above technical solution, the elastic member 301 is clamped by the cavity wall and the electronic pin 302 in the cavity 101 and is in a slightly compressed state, in this way, when the male and female terminals are not in contact, the electronic pin 302 is fixedly extended out of the cavity 101 through the slightly compression of the spring, so that the electronic pin 302 and the elastic member 301 cannot shake back and forth when not in use.
