Detailed Description

In order that the objects, aspects and advantages of the present invention will become more apparent, the invention will be further described in detail with reference to the following detailed description and accompanying drawings.

It should be noted that all expressions of "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name or different parameters, and it is understood that "first" and "second" are merely for convenience of description and should not be construed as limiting the embodiments of the present invention, and that the directions and positions of the terms, such as "up", "in", "down", "before", "after", "left", "right", "inside", "outside", "side", etc., in the present invention are only referred to the directions and positions of the attached drawings, and therefore, the directions and positions are used for explaining and understanding the present invention, and are not used for limiting the subsequent embodiments of the present invention.

As shown in the figures, the branch cable with the alarm module provided based on the above purpose includes a main cable 1, a plurality of branch cables 2 arranged on the main cable 1, and a connection module 3. The main cable 1 is provided with a plurality of exposed parts. One end of the branch cable 2 is electrically connected with the main cable 1 through an exposed part. The connecting module 3 is arranged at the joint of the branch cable 2 and the main cable 1 and used for fixing and insulating the joint of the branch cable 2 and the main cable 1. In this way, the branch cable 2 is fixed to the main cable 1 and can conduct electric current from the main cable 1. When the alarm module is installed, the branch cable with the alarm module is directly laid, and extra wiring is not needed. The construction period of cable laying is greatly shortened. And prefabricated branch cable 2 is reliable with being connected of main push-towing rope 1, and is insulating also reliable, can effectively avoid the electric power constructor that the business ability is unskilled to lead to the emergence of wiring error because of human error.

In order to facilitate the fixed connection, the connection module 3 includes a sub clip 31 and a female clip 32, the sub clip 31 and the female clip 32 are both in a strip structure, the cross section of the sub clip 31 and the female clip 32 is in an arc shape, the arc radius of the outer layer of the sub clip 31 is equal to the arc radius of the inner layer of the female clip 32, the sub clip 31 is arranged at the connection position of the branch cable 2 and the main cable 1, and the female clip 32 clips the sub clip 31 from the notch of the sub clip 31.

In order to enhance the connection stability and prevent relative sliding and relative rotation between the female latch 32 and the male latch 31, the connection module 3 further includes a plurality of fixing strips 33 disposed outside the female latch 32. The fixing strip 33 clamps the female buckle 32 and tightens the female buckle 32, so that the female buckle 32 is firmly fixed on the sub buckle 31, and the sub buckle 31 is tightly contacted with the main cable 1 or the branch cable 2.

In order to conveniently observe the tension condition between the main cable 1 and the branch cables 2, the connection module 3 further comprises a plurality of safety ropes 34 arranged on the branch cables 2 and the main cable 1, and two ends of each safety rope 34 are respectively connected with the branch cables 2 and the main cable 1. Among the safety cords 34, the length of the safety cord 34 is shorter as it is closer to the connection between the sub cable 2 and the main cable 1. When the number of broken safety ropes 34 is too large, it is necessary to check whether the connection between the main cable 1 and the sub-cable 2 where the safety rope 34 is located is still firm.

In order to find the broken safety rope 34 timely and accurately, a detection circuit is arranged inside the safety rope 34, a power supply of the detection circuit is arranged on the branch cable 2, and the detection circuit extends out of the safety rope 34 and is electrically connected with the power supply. When the safety cord 34 breaks, the detection circuit including the power supply line and the signal transmitting device provided on the power supply line also breaks. After the detection circuit is broken, the signal transmitting device can transmit a breaking signal outwards. The user can read which position of the safety rope 34 on which branch cable is broken by receiving the signal transmitting device through the receiving device and transmitting a breaking signal outwards.

In order to save energy, the detection circuit further comprises a timing device arranged on the power line. The timing device is in electric signal connection with the signal transmitting device, when the detection circuit is broken, the timing device starts to repeat timely, and when the timing device returns to zero, the signal transmitting device transmits a signal to the outside once.

To ensure that the detection circuit breaks along with the safety line 34, the detection circuit is in the shape of a closed loop, the length of the closed loop along the length of the safety line 34 is approximately equal to the length of the safety line 34, and the length of the closed loop perpendicular to the length of the safety line 34 is approximately equal to the width of the safety line 34.

To set the length of each safety line 34, the difference in length between any two adjacent safety lines 34 is less than 2 millimeters. This ensures that the safety line 34 breaks in sequence from the safety line 34 far from the connection between the main cable 1 and the sub-cable 2 to the safety line 34 near the connection between the main cable 1 and the sub-cable 2.
