(Summary description)The power harness provides a complete set of service equipment for a certain load source group, such as relay lines, switchgear, control system, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and harness capacity. Electric tool harness is an important basic concept in traffic theory. In the prior art, the power supply electric tool harness is broken due to pulling during use, and the power supply harness is easy to catch fire. When a fire breaks out, it spreads quickly and is not easy to put out. Therefore, it is necessary to invent a main switching power supply harness to solve the above problems.

The power harness provides a complete set of service equipment for a certain load source group, such as relay lines, switchgear, control system, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and harness capacity. Electric tool harness is an important basic concept in traffic theory.

Technical elements:

In order to achieve the technical purpose of the electric tool harness, the patent technology of this utility model provides the following technical scheme: the main switch power supply electric tool harness includes power supply harness, wires and power set. It describes the activities outside the external set, describes the structure of the external sleeve bellows, sets one end of the power supply plug, and fixes the plastic shell on the surface of the plug. The plastic sleeve is connected to the power supply wire and plug, and the plastic shell is fixed externally at the end of the year. The inner ring of the jacket is provided with an air bag, which is arranged between the power supply harness and the jacket; the air bag is provided with a tank for storing fire extinguishing media; the cross section of the air bag is a semicircular shell structure; the air bag is round; and a plurality of groups are distributed on the outer ring of the power supply electric tool harness.

Technical effects and advantages:

The utility model relates to a main switch power supply electric tool harness, which comprises a power supply harness, wherein the power supply harness and the power supply set are provided with a movable external device, and the external device is provided with a bellows structure; the external device pulls the power supply harness and contacts with the external device, so that the external device can make the power supply harness slide on the external surface of the power supply set, and the phenomenon of forcibly stretching the power supply harness is avoided, thus playing a protective role.

Electric tool harness circuit principle:

After full-bridge rectification and LC filtering, the commercial power supplies the DC voltage for the whole circuit. When the commercial power exceeds 270V, the varistor U protects the circuit. R1 and RP1 deviate from V1. Note that the bias must be reduced from high to low to avoid damaging V1. T, C4 and C5 form LC oscillation, and its working frequency is about 50kHz~150kHz. 2. QLs, L3, C7, C8 and C9 provide rectified and filtered outputs. The output voltage can be determined by the secondary winding T, or additional windings can be added as required. V2 is protected by thermistor R4 for current limit. The thermistor is attached to the heat dissipation plate. When the temperature or circuit current is too high, the heat dissipation plate heats up, R4 resistance decreases, V2 turns on, and V1 gate voltage decreases, thus protecting the whole circuit. When the temperature decreases, the circuit returns to normal. Pay attention to Liushi connector to learn more about power tool harness.
