Description

Technical Field

[0001] The utility model relates to the technical field of terminal production and manufacturing, in particular to a shielding wire shaping structure. Background Art

[0002] For the traditional production process of Fakra products of coaxial cables, in order to ensure the mechanical properties of the terminals in subsequent processing, the requirement for turning the shielding wire is that the shielding wire needs to be evenly laid on the shielding ring. However, when the outer conductor is crimped subsequently, one or several shielding wires will be squeezed into the crimping seam, affecting the crimping appearance and at the same time affecting the mechanical properties of the terminal (the pulling force of the outer conductor terminal). Summary of the Invention

[0003] Aiming at the above problems existing in the existing outer conductor crimping, the present invention aims to provide a shielding wire shaping structure that improves the aesthetics and ensures the stable mechanical properties of the terminal.

[0004] The specific technical solutions are as follows:

[0005] A shielding wire shaping structure includes a terminal fixing tooling and a nozzle. The terminal fixing tooling is used to position a terminal on which a plurality of shielding wires have been laid flat. The nozzle is arranged directly above the terminal fixing tooling and is operable to spray compressed air with a certain pressure towards the terminal to blow and separate the plurality of shielding wires towards both sides.

[0006] As a further improvement and optimization of this solution, the top of the terminal fixing tooling has a positioning groove, and the terminal is in positioning fit with the positioning groove.

[0007] As a further improvement and optimization of this solution, the separation angle of the plurality of shielding wires separated towards both sides is 30 - 60°.

[0008] As a further improvement and optimization of this solution, the air pressure of the compressed air ejected by the nozzle is 4 - 6 bar.

[0009] As a further improvement and optimization of this solution, the single - time air - jet duration of the nozzle is 0.5 - 2 seconds.

[0010] As a further improvement and optimization of this solution, the nozzle is connected to an air pump.

[0011] As a further improvement and optimization of this solution, the terminal has an outer conductor, and a plurality of the shielding wires are located outside the outer conductor.

[0012] The positive effects of the above - mentioned technical solutions compared with the prior art are:

[0013] In the present utility model, compressed air with a certain pressure is ejected through a nozzle to blow several shielding wires apart towards both sides. By adjusting the area where the shielding wires are located, the shielding wires at the position after the formation of the crimping wings are reduced, and the appearance of the shielding wires in this area is avoided. This can not only prevent the shielding wires from appearing in the crimping seam and improve the overall aesthetics of the terminal appearance, but also ensure the mechanical properties of the terminal.
