摘要: An improved high frequency selecting switch terminal comprising two conductor pins which are coaxial. When a conductor pin from a cable is inserted into the terminal, it pushes the front end of the first conductor pin forward into the front end of the second conductor pin. At the front ends of the first and second conductor pins are first and second sliding blocks which force the pins forward. Thus, input signals are transmitted from the cable to the switch. The terminal further comprises a thick film resistor which connects the front end of the second conductor pin and a conductor ring which is disposed on the front surface of the second sliding block. When the cable is removed, the first and second sliding blocks move to the original position and the conductor ring contacts with the rim of the terminal housing. In this way, the terminal absorbs undesirable signals from the surroundings so as to prevent interference.

摘要: A Hi-Fi audio signal optical fiber cable has an optical fiber bundle provided coaxially inside a snake tube. The optical fiber bundle has multiple optical fibers. Both ends of the optical fiber bundle protrude from the snake tube and are installed with a connector respectively. An air gap is formed between the optical fiber bundle and the snake tube so that ordinary air fills in the air gap. When a signal source inputs an optical signal via one connector, the optical signal is transmitted within each optical fiber by total reflection and goes out from the other connector. Since the refractive indices of the optical fiber bundle and the air have a significant difference, the total reflection is better, thereby achieving high fidelity. Each optical fiber has a smaller numerical aperture, and the optical path of the optical signal is shorter and signal attenuation in the material is avoided.
摘要翻译: Hi-Fi音频信号光纤电缆具有同轴地设置在蛇管内的光纤束。 光纤束具有多根光纤。 光纤束的两端从蛇管突出,分别安装有连接器。 在光纤束和蛇管之间形成气隙,使得普通空气填充在气隙中。 当信号源通过一个连接器输入光信号时,光信号通过全反射在每个光纤内传输,并从另一个连接器出来。 由于光纤束和空气的折射率具有显着差异,所以全反射更好,从而实现高保真度。 每个光纤具有较小的数值孔径,光信号的光路更短,避免了材料中的信号衰减。
