Particularly, one of the characteristics of the present embodiment is that the distance between the signal wires 33s and the protection member 40 is greater than the distance between the non-signal wires 33g and the protection member 40. For example, the distance difference is at least 0.5 mm. The main function of this design is that the non-signal wire 33g is used for power transmission or grounding, and the signal wire 33s is used for high-frequency signal transmission, so as to avoid the phenomenon of spark-over (or arc) that generates point discharge during hot insertion and damages the wire or the device end parts, therefore, the above structure provides a design of contact timing difference.
