High-precision torsion type round-covered terminal

Technical Field

The utility model relates to a terminal connection structure's field, concretely relates to high accuracy torsion type package circle terminal.

Background

Conventional high speed connector for backplate contacts interface signal to the mode of arranging as shown in figure 3 for level or perpendicular arranging, whole occupation space is great, and jump point can appear during high frequency signal transmission, along with high speed connector to high density, frivolousization direction development, it is not enough more and more obvious, and contact interface needs carry out optimal design, and the terminal also needs carry out corresponding adjustment simultaneously.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a high accuracy torsion type package circle terminal, both satisfied high-speed connector high density requirement, satisfied the high-speed transmission requirement of signal again.

The purpose of the utility model is accomplished through following technical scheme: the high-precision torsion type round-covered terminal comprises a horizontal part and a torsion part, wherein the horizontal part is of a sheet structure, the end part of the horizontal part is fixedly connected with the torsion part through a terminal torsion structure, the terminal torsion structure extends outwards to form a terminal torsion clamping plane for a stamping torsion process, the terminal torsion clamping plane extends outwards and forms a terminal round-covered structure through a round-covered process, and the end part of the terminal round-covered structure extends outwards to form a terminal hanging table.

As a further technical scheme, the end of the terminal rounding structure extends to the upper side and the lower side to form two symmetrical terminal hanging platforms, and a terminal contact area is formed at the position, close to the terminal rounding structure, of each terminal hanging platform.

As a further technical scheme, one end of the horizontal part close to the terminal torsion structure is provided with a terminal assembly positioning hole for accurate positioning of the terminal.
