Embodiment

The utility model provides a kind of outdoor control cable, is in order to the transmission electric power that TRT produced, and the outdoor control cable of the utility model is that two kinds of embodiment are arranged, and Fig. 1,2,3 is first embodiment, and Fig. 1,4,5 is second embodiment.

Open air control cable like Fig. 1,2, first embodiment shown in 3 comprises: a cable 1, an earth terminal 2, a plurality of other terminal 3 and a joint 4.

This cable 1 is to comprise an insulation-coated crust 10, a plurality ofly be coated with the power line 11 of insulating barrier 15, an a plurality of RCA 12 and metallic shield 14 that is coated with insulating barrier 15 respectively respectively; These a plurality of power lines 11 are to be coated in this insulation-coated crust 10 with these a plurality of RCAs 12; And these a plurality of RCAs 12 also are coated in this metallic shield 14; As shown in Figure 3, to prevent to come from the electromagnetic interference of power line 11 through metallic shield 14, certainly; If can be further RCA 12 in twos be wound in twisted pair wire each other, then more can further reduces the interference between RCA.Wherein, power line 11 is to use transferring electric power, and RCA 12 is then in order to transmission signal; As for 14 of this metallic shields is an aluminium foil element.

This earth terminal 2 is to be electrically connected at this metallic shield 14, in other words, just electromagnetic interference is given ground connection and the earth that leads; These 3 of a plurality of other terminals are electrically connected at respectively this power line 11 and respectively this RCA 12 respectively.

This joint 4 is shell 41, a socket 42 and protruding said earth terminal 2 and a plurality of other terminals 3 that are exposed in this socket that comprise the system of moulding.

Open air control cable like Fig. 1,4, second embodiment shown in 5 comprises: a cable 1, an earth terminal 2, a plurality of other terminal 3 and a joint 4.

This cable 1 is to comprise an insulation-coated crust 10, a plurality of power line 11 of insulating barrier 15, a plurality of RCA 12, a metallic shield 14 and grounding terminal 13 that is coated with insulating barrier 15 respectively of being coated with respectively; This a plurality of power line 11, these a plurality of RCAs 12 and grounding terminal 13 are to be coated in this insulation-coated crust 10; And these a plurality of RCAs 12 also are coated in this metallic shield 14 with this grounding terminal 13; This grounding terminal 13 is electrically to be contacted with this metallic shield 14; As shown in Figure 5, to prevent to come from the electromagnetic interference of power line 11 through metallic shield 14, certainly; If can be further RCA 12 in twos be wound in twisted pair wire each other, then more can further reduces the interference between RCA.Wherein, power line 11 is to use transferring electric power, and RCA 12 is then in order to transmission signal; As for 14 of this metallic shields is an aluminium foil element.
