AI Technical Summary

Problems solved by technology

The structural characteristics of this device make its applicability limited. For example, when the device needs to be fixed at a specific position, when the cable on the far side of the connecting device is laid out to a suitable length, it is closer to the connecting device. The cables on one side are still released to the same length. The cables that are too long not only cause waste, but also need to be bundled or stacked, which makes the work of cable arrangement very cumbersome, and the cables are easy to be messy and cause difficulty in line inspection.

Embodiment Construction

[0013] Below in conjunction with accompanying drawing for further explanation:

[0014] Such as figure 1 As shown, the inner end of the scroll spring 2 is fixedly connected to the central shaft 1 of the present invention, and the outer end of the scroll spring is connected to the inner circle of the coil 3 . A wiring mechanism 4 is provided on the reel, which is composed of a wiring terminal 5 on one side and a conducting contact 6 on the other side, see figure 2 , the connecting terminal and the conduction contact are electrically connected.

[0015] Such as image 3 As shown, a circular line row 7 coaxial with the winding reel is arranged on one side of the wiring contact of the winding reel. External terminal 9, see Figure 4 , the center of the circular row is fixed on the central axis. The wires on the circular line bar are exposed on one side facing the contacts, and are in one-to-one contact with the conduction contacts of the wiring mechanism.

[0016] The wirin...

Abstract

The invention relates to a twisted-pair one-way telescopic rotating and connecting apparatus. The twisted-pair one-way telescopic rotating and connecting apparatus is characterized by comprising a central shaft, a volute spiral spring fixed on the central shaft, a wire spool connected with the volute spiral spring and a circular line bank coaxial with the wire spool. When the twisted-pair connecting apparatus is in use, the length of a cable can be optionally adjustable; a wiring apparatus also can be fixed at any position; in addition, accumulation of redundant cables also can be avoided, so that the equipment site can be concise and tidy; and furthermore, the twisted-pair one-way telescopic rotating and connecting apparatus is simple in structure, convenient to maintain, and particularly suitable for placement occasions for relatively large equipment.

Description

technical field [0001] The invention relates to a cable connection device, in particular to a twisted pair one-way telescopic rotary connection device. Background technique [0002] Existing retractable cable connection devices are usually composed of a take-up shaft with a helical spring leaf on the axis. When the cable wound on it is pulled out, the spring leaf on the take-up shaft is tightened, and when it is released When the cable is connected, the spring leaf returns elastically to retract the cable. This structure determines that the pulling out and retracting of the cable are bidirectional, that is, the two ends of the cable are retracted and retracted at the same time and the retracted and retracted length is the same. The structural characteristics of this device make its applicability limited. For example, when the device needs to be fixed at a specific position, when the cable on the far side of the connecting device is laid out to a suitable length, it is close...
