The present invention relates to connectors, and more particularly, to a metal contact member with elastic arm for connectors.
With science and technology advancement, connectors have a plug and play function, so as to be widely used. The iron case of the female socket of conventional connectors is usually formed of an upper and a lower elastic plates or convex hulls formed by metal parts. However, the elastic plates only provide the contact function and do not provide an insertion and withdrawal force. Current products on the market are unable to meet higher requirements.
The present invention aims at increasing the insertion and withdrawal force during the plugging operation between the female socket and the male sockets, and simultaneously achieving a structural optimization.
For achieving the aforementioned objectives, a Type-C female socket iron case is provided, comprising an iron case main body, the iron case main body being configured to be plugged with a male socket;
Preferably, the insertion and withdrawal force of the elastic arm is an insertion and withdrawal force of 4 to 6 Newton when male head and female head connectors are plugged.
Preferably, the elastic arm is arranged in parallel with two sides of the square cylindrical case.
Preferably, the first weld leg comprises an engagement notch on an end thereof; the second weld leg comprises an engagement notch on an end thereof.
Preferably, a tail part of the extension part is bent upward.
Preferably, at least two engagement points are disposed on the upper surface of the extension part; the engagement point is internally convex, so as to increase a stableness of a combination with a male socket.
With such configuration, the present invention achieves following advantages.
Compared with prior arts, the Type-C female socket iron case of the present invention applies a design of elastic arm. With the pushing force of the convex elastic arm, the insertion and withdrawal force of Type-C female and male sockets combination is improved. The iron case is bent by formation of a metal plate material, so as to improve the insertion and withdrawal force of Type-C female and male sockets combination, and simultaneously fulfill Test Identification (TID) certification requirement. The present invention fulfills the TID certification requirement and increases the insertion and withdrawal force without Electro Magnetic Compatibility (EMC). Therefore, the present invention improves the insertion and withdrawal force of Type-C female and male sockets combination through the elastic arm of the iron case, and fulfills the TID requirement.
The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

The insertion and withdrawal force of the elastic arm 113 is an insertion and withdrawal force of 4 to 6 Newton when male head and female head connectors are plugged. The elastic arm 113 is arranged in parallel with two sides of the square cylindrical case 11. The first weld leg 112 comprises an engagement notch 1121 on an end thereof; the second weld leg 122 comprises an engagement notch 1221 on an end thereof. A tail part of the extension part 12 is bent upward. At least two engagement points 123 are disposed on the upper surface of the extension part 12. The engagement point 123 is internally convex, so as to increase a stableness of a combination with a male socket.
