Connector, metal terminal mounting structure and metal terminal

Abstract

The invention relates to a metal terminal mounting structure, which comprises an insulator and a metal terminal. A mounting hole for accommodating the metal terminal is arranged in the insulator, the metal terminal is provided with a main body part and a contact part extending along the main body part, two sides of the main body part are respectively provided with a forced mounting interference point, and the forced mounting interference points on the two sides are distributed in an up-down staggered manner. The two sides of the orifice of the mounting hole are distributed in a vertically staggered manner, so that the forced mounting interference point on each side is simultaneously contacted with the orifice on the corresponding side of the mounting hole in the process of inserting the metal terminal into the mounting hole. Crimping assembly is carried out by adopting a metal terminal forced mounting mode, and assembly limiting is realized by virtue of the limiting bulge, so that the assembly efficiency and the structural stability of the connector are improved; the forced mounting interference points at the two sides of the metal terminal are distributed in a vertically staggered manner, and adaptive structural design is carried out at the two sides of the orifice of the mounting hole, so that the interference points at the two sides are balanced in stress and do not deflect in the insertion process of the metal terminal, and the SI performance of the connector is improved.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a connector, a metal terminal installation structure and a metal terminal thereof. Background technique [0002] In the field of electrical connectors, such as various connectors that transmit differential signals, metal terminals are generally fixed by buckle, glue or insulator snap-fit ​​or integrated injection molding with insulator, which has low production efficiency and is not suitable for In the application environment where metal terminals are densely distributed, the method of forced fit of metal terminals generally relies on protrusions for interference limit, which makes it difficult to ensure the terminal position under frequent vibration or many times of plugging and unplugging, which may lead to terminal failure. Offset or movement occurs along the plugging and unplugging direction. In addition, the SI performance of the connector needs to be improved due to the ...

[0002] In the field of electrical connectors, such as various connectors that transmit differential signals, metal terminals are generally fixed by buckle, glue or insulator snap-fit ​​or integrated injection molding with insulator, which has low production efficiency and is not suitable for In the application environment where metal terminals are densely distributed, the method of forced fit of metal terminals generally relies on protrusions for interference limit, which makes it difficult to ensure the terminal position under frequent vibration or many times of plugging and unplugging, which may lead to terminal failure. Offset or movement occurs along the plugging and unplugging direction. In addition, the structural design of the existing metal terminals causes the SI performance of the connector to be improved.
