[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0017] like Figure 1-2 As shown, a cable anti-theft auxiliary device includes an anti-theft housing 1, a first normally closed contact 301, a second normally closed contact 201, an intermediate relay 7 and a short-circuit 10, a loudspeaker 2 is fixedly installed on the front surface of the anti-theft housing 1, an alarm light 3 is fixedly installed on the upper surface of the anti-theft housing 1, a status light 4 is fixedly installed on the upper surface of the anti-theft housing 1 on one side of the alarm light 3, a key switch 5 is fixedly installed on one side of the anti-theft housing 1, wherein the key switch 5 can be unlocked by being equipped with a matching key to avoid the situation where the thief directly turns off the alarm device, a negative lead wire 8 and a positive lead wire 9 are connected to one side of the anti-theft housing 1 above the key switch 5, and a lithium battery 6 is fixedly installed inside the anti-theft housing 1;
[0018] A charging interface is fixedly installed on the other side surface of the anti-theft housing 1, and the charging interface is electrically connected to the input terminal of the lithium battery 6. The charging interface is used to charge the lithium battery 6 to ensure normal power supply at night; the positive electrode of the lithium battery 6 is connected to the positive electrode lead wire 9, the key switch 5 is connected to the positive electrode lead wire 9, the negative electrode of the lithium battery 6 is connected to the negative electrode lead wire 8, and the intermediate relay 7 is connected to the negative electrode lead wire 8; the other ends of the negative electrode lead wire 8 and the positive electrode lead wire 9 are short-circuited by the cable 11 and the short-circuit wire 10 The alarm light 3, the loud speaker 2, the status light 4 and the intermediate relay 7 are connected in parallel, the alarm light 3 and the loud speaker 2 are connected in parallel between the negative lead wire 8 and the positive lead wire 9, the status light 4 and the intermediate relay 7 are connected in parallel on the positive lead wire 9, and the intermediate relay 7 and the key switch 5 are connected in series through the negative lead wire 8, the positive lead wire 9, the short-circuit wire 10 and the cable 11; the alarm light 3 is connected in series with the first normally closed contact 301, and the loud speaker 2 is connected in series with the second normally closed contact 201.
[0019] It should be noted that the utility model is a cable anti-theft auxiliary device.
