After the indoor soft optical cable 1 is installed, light-emitting terminals are provided at both ends thereof near the connector plug assembly 2. The light-emitting terminals at both ends of the indoor soft optical cable are electrically connected by the indoor soft optical cable. An excitation power supply (not shown in the figure) is electrically connected to the light-emitting terminal at any end of the indoor soft optical cable 1, and the light-emitting terminal at that end of the indoor optical cable 1 is illuminated. At this time, the light-emitting terminals at both ends of the same indoor soft optical cable 1 are illuminated at the same time. The light-emitting terminals on the indoor soft optical cable 1 are observed at the other end of the indoor soft optical cable 1. Among multiple indoor soft optical cables 1, the indoor soft optical cable 1 with a light-emitting terminal that is lit is the indoor soft optical cable 1 to be found.

[0027] The indoor soft optical cable 1 used in this embodiment is as follows Figure 1 and Figure 2 As shown, the indoor soft optical cable 1 is provided with connector plug assemblies 2 at both ends when in use. The connector plug assembly 2 in this embodiment is a prior art, and various single-core pre-terminated connectors such as standard SC, LC, FC, ST, or dual-core LC pre-terminated connectors or various on-site connectors or non-standard customized connectors can be used. The indoor soft optical cable 1 in this embodiment includes a fiber core 3, a reinforcement member 4, and a soft optical fiber protective sleeve 5. The reinforcement member 4 in this embodiment adopts a steel twisted wire with good bending resistance and compression resistance and electrical conductivity. The light-emitting terminals at both ends of the indoor soft optical cable are electrically connected by the reinforcement member 4. The soft optical fiber protective sleeve 5 is coated on the reinforcement member 4 and the fiber core 3, and separates the reinforcement member 4 from the fiber core 3. The fiber core 3 in this embodiment can be one or two, corresponding to a single-core or dual-core optical cable, respectively. Figure 2 The cross-sectional view of a single-core optical cable is shown. When the embodiment is configured as a dual-core optical cable, the two optical fiber cores 3 are also separated by a soft optical fiber protective sheath 5 .

The light-emitting terminal of this embodiment includes a terminal housing 7, an LED light-emitting diode 8 and an electrode thorn 9. The terminal housing 7 includes a terminal bottom 10 and a terminal cover 11. The terminal cover 11 can be buckled on the terminal bottom 10, so as to fix the terminal housing 7 on the indoor soft optical cable 1. The LED light-emitting diode 8 and the electrode thorn 9 are both arranged in the terminal bottom 10. The pins of the LED light-emitting diode 8 are connected to the electrode thorn 9. The electrode thorn 9 is made of metal material. A transparent window 12 is provided on the terminal bottom 10 for transmitting the light emitted by the LED light-emitting diode 8. Two holes are provided on the transparent window 12 to be opposite to the two pins of the LED light-emitting diode 8. The corresponding connection hole can connect the LED light emitting diode 8 and the electrode thorn 9 to the power supply when in use. When the present embodiment is fixed to the indoor soft optical cable 1, the indoor soft optical cable 1 is placed on the terminal bottom 10 and the terminal cover 11 is buckled on the terminal bottom 10 to clamp the indoor soft optical cable 1. At this time, the electrode thorn 9 pierces the soft optical fiber protective cover 5 of the indoor soft optical cable 1 and contacts the reinforcement member 4, so that the steel hinge reinforcement member 4 is electrically connected to the electrode thorn 9 and the LED light emitting diode 8. When the pin of the LED light emitting diode 8 is directly connected to the power supply 32 or the reinforcement member 4 is connected to the power supply 32, the LED light emitting diode 8 emits light. In the present embodiment, the light emitting terminal at one end of the indoor soft optical cable 1 is powered on, and the LED light emitting diodes 8 of the light emitting terminals at both ends of the indoor soft optical cable 1 are all illuminated, so that the same indoor soft optical cable 1 can be determined from both ends of the indoor soft optical cable 1.

[0030] like Figure 3 and Figure 4As shown, in this embodiment, an optical cable channel 13 is opened at the top of the terminal bottom 10 along its length direction and runs through both ends thereof. The optical cable channel 13 is a rectangular channel. A diode mounting groove 14 is opened at the bottom of the optical cable channel 13 on the terminal bottom 10. The shape of the diode mounting groove 14 matches the shape of the LED light-emitting diode 8. The LED light-emitting diode 8 is arranged in the diode mounting groove 14.

In the use state, the two electrode thorns 9 pierce the soft optical fiber protective cover 5 of the indoor soft optical cable 1 from both sides of the fiber core 3, and respectively contact the two reinforcement members 4. The two pins of the LED light-emitting diode 8 are respectively connected to the two electrode thorns 9.

In the best embodiment of this embodiment, a thorn 20 is arranged at each end of the spike portion 17. When the terminal cover 11 is buckled on the terminal bottom 10 with force, the thorn 20 is squeezed and pierces the soft optical fiber protective cover 5 of the indoor soft optical cable 1, and the tip of the thorn 20 contacts the reinforcement member 4. The bottom of the fixing portion 16 is connected to the bottom of the spike portion 17 by the connecting portion 18, wherein the fixing portion 16 is located in the electrode thorn card slot 15, and the spike Due to the setting of the connecting portion 18, the portion 17 extends into the optical cable channel 13, thereby piercing from both sides of the indoor soft optical cable 1 and contacting the two reinforcement members 4 respectively. The elastic contact point 19 in this embodiment is fixedly connected to one end of the connecting portion 18 close to the LED light-emitting diode 8, and is used to contact the pins of the LED light-emitting diode 8 when in use. The elastic contact point 19 in this embodiment is tilted downward, thereby pressing the pins of the LED light-emitting diode 8. The fixing portion 16, the spike portion 17, the connecting portion 18 and the elastic contact point 19 in this embodiment are made of elastic metal sheets after cutting and bending, and their integrated structure ensures the overall strength of the electrode thorn 9.

The shape of the limiting protrusion 22 corresponds to the shape of the limiting hole 21. When the electrode thorn 9 is installed in the electrode thorn slot 15, the limiting protrusion 22 is located in the limiting hole 21. The limiting protrusion 22 is used to prevent the electrode thorn 9 from moving up and down in the electrode thorn slot 15, thereby fixing the electrode thorn 9.

[0033] like Figures 3 to 5 As shown, the terminal housing 7 in this embodiment is provided with a connecting plate 23, and the connecting plate 23 connects the terminal bottom 10 and the terminal cover 11. An indentation 24 is provided at the connection between the connecting plate 23, the terminal bottom 10 and the terminal cover 11, so that the terminal bottom 10 and the terminal cover 11 can be flipped relative to the connecting plate 23.
