Description
Technical Field
The invention relates to an electric appliance and an installation method thereof, in particular to an anti-breaking structure of an electric wire led out by the electric appliance and an installation method thereof.
Background
It is known that the outgoing wires of electrical appliances, in particular hand-held electrical appliances with large vibrations and/or bending angles, are easily broken. In order to reduce the chance of breakage of the outgoing wire, a wire jacket is typically added between the end of the wire and the consumer. As shown in fig. 1, a conventional structure for drawing out an electric wire from an electric appliance comprises a wire (electric wire) 2 and an electric appliance housing 3, wherein the wire (electric wire) 2 is connected with the electric appliance housing 3 in a protection manner through a wire protecting tube 1, the end part of the wire (electric wire) 2 penetrates through the wire protecting tube 1, the front part of the wire protecting tube 1 presses the end part of the wire (electric wire) through a tube head pressing plate 3-1, the end part of the wire (electric wire) 2 is fixedly connected with the electric appliance housing 3 through a gasket 3-2 and a screw 3-3, and the middle part of the wire protecting tube 1 is a flexible part (the middle part of the protecting tube 1 in fig. 1). The wire protector has the protection, so the breakage probability of the outgoing wire is reduced, but the effect is less obvious. After the electromagnetic heating welding gun produced by the applicant is sold, the problem that a customer reflects the breakage of an outgoing wire of the electromagnetic heating welding gun often exists, and the applicant knows that the breakage of the outgoing wire exists in a plurality of handheld electric appliances (such as impact drills, hole drills, climbing welding machines, hot air welding guns, vibrators, electric coal drills, grinding machines with various sizes and models, electric ramming machines and the like). This problem appears to be small and is addressed by the customer simply cutting off a section and re-splicing back and/or replacing a new wire protector and reinstalling it. However, the problem of frequent disconnection brings great trouble to the clients, even if the outgoing line is disconnected to repair the machine in the factory, great economic loss is caused to the clients due to the prolonged construction period. To solve this problem, the applicant has spent a long time (about three years) performing numerous experiments, such as increasing the wall thickness of the wire guard tube, the fracture probability being not significantly reduced, and the wire guard tube made of hard material not only does not reduce the fracture probability but increases the fracture probability. The applicant has made a search of a great deal of scientific literature and has not found the cause of wire breakage. In order to find out the reason of the wire breakage, the applicant invests a great deal of funds to purchase experimental equipment, carries out a great deal of experiments, finally finds out the reason of the wire breakage, and carries out substantial improvement on a wire protection tube structure, a wire end structure, an anti-breakage structure of an electric wire led out by an electric appliance and an installation method thereof in the prior art.

Compared with the prior art, the wire protection tube structure has the following beneficial effects.
1. According to the technical scheme, the wire protection tube is made of flexible materials and is provided with the threading hole, the axis direction of the threading hole is along the length direction of the wire protection tube, the wire protection tube is provided with a fixing structure and/or a fixing component for preventing the wire from moving backwards after being positioned at the position where the wire is easy to bend, the axial force born by the part of the wire at the position where the wire is repeatedly bent (from the front part of the wire positioned in the wire protection tube to the position where the wire is fixed) is extremely small, and the wire is not easy to break in the repeated bending process; the part of the wire subjected to axial force (after the wire is fixed) is not easy to repeatedly bend and break, so that the wire protection tube structure can obviously reduce the breaking probability of the outgoing wire and create favorable conditions for smooth construction of customers.
Here, the applicant has to explain the own knowledge of the cause of the breakage of the electric wire. Applicant has made detailed observations and ideas in long-term working practice. The common high-speed rail or high-speed tunnel has a height of about nine meters, when working at a high place, the operating wire is always affected by gravity to the lower position when holding the gun handle to work, and the downward pulling force enables the wire in the wire protection tube to be subjected to the action of repeated bending moment while being subjected to axial acting force, and the operating wire of nine meters weighs about two kilograms, so that the wire core in the wire protection tube is easily damaged.
In order to greatly reduce or even eliminate the axial force applied to the wire core in the wire protection tube, the end part of the wire is fixedly connected with the rear end of the wire protection tube, so that the axial force applied to the part of the wire at the repeated bending position (from the front part of the wire in the wire protection tube to the position before the wire is fixed) is extremely small or even zero, and the wire is not easy to break in the repeated bending process; meanwhile, the wire is not easy to repeatedly bend and break at the part subjected to axial force (after the wire is fixed). To get the experimental verification, the applicant spends great expense in purchasing wire bending machines.
In the experimental process of the wire bending machine simulation, in order to unify experimental conditions, the bending swing angle is uniformly 180 degrees, the bending swing speed is uniformly 29 times per minute, the balance weight is uniformly two 500 g hanging weights, one 300 g hanging weight and the total weight of the three hanging weights is 1300 g.
And (3) unifying operation lines: six-core cables with the ratio of 2 times 2.5 and 4 times 1 are used in the same group of experiments, or five-core cables with the ratio of 2 times 2.5 and 3 times 1 are used in the same group of experiments, and the same cable segment test is used for testing and comparing accurately.
And the broken line counting standard is unified: the broken first line is used as a counting standard.
The wire bending machine can simultaneously obtain six groups of wires at a time, and because the indicator lamps are limited and the test load with the gun shell is heavy, only two groups of wires are needed.
Firstly, testing a common sheath for comparison, wherein the common sheath can be bent for 3-9 thousand times to break a fine wire core.
The sheath tube can be bent for about 2.5 to 3 ten thousand times, so that a fine wire core is broken. The wire breakage probability is obviously reduced.
When the protective sleeve is used, lubricating oil is added into the protective sleeve, and the protective sleeve can be bent for about 4-5 ten thousand times, so that a fine wire core is broken. The wire breakage probability is further significantly reduced.
Because the wire protection tube is much thicker than the traditional wire protection tube, in order to prove that the bending times are increased only by thickening the wall of the protection tube, the tail part of the wire protection tube is not fixed, the wire protection tube is fixed with a clip in a gun like the traditional protection tube, and under the condition that lubricating oil is not added, the experimental result is about 1.2 to 2 ten thousand times, and a fine wire core is broken.
To investigate why the thread is always broken, we used various cables and various mounting means, and finally let us have unexpected harvest, we found that when the cable is threaded into the protective tube, the outer skin of the cable is removed by about five millimeters beyond the locking position, the cable is placed in the protective tube in a spiral loose manner, six wires are all put in the protective tube, and the thick wire is broken first after more than 42 ten thousand times (the mounting means will be described later in detail).
In another group of experiments, two thick lines in six are corrugated, four thin lines are wound on the two thick lines and put into a protective tube, and the thin lines are bent for 38.2 ten thousand times and are cut off first.
According to experimental result analysis, when the bending reaches 180 degrees, the bending position of the protective tube is about 10 cm, the average bending angle of each cm is 18 degrees, when the electric wires are in spiral shape and corrugated shape, the actual pulling length of the electric wires is greater than 10 cm, and the bending angle averaged down by the length of the straightening wires is less than 18 degrees.
Simultaneously, because the lubricating oil is arranged in the protective tube, the external resistance of the wire is reduced, and the wire can be bent at a maximized uniform bending angle.
Meanwhile, the rear part of the wire protecting tube is locked and fixed, so that the electric wire can be loosely arranged in the wire protecting tube in a spiral and corrugated mode without being straightened.
Because the fire tube is strict, the work factory is powered off, the last test takes more than twenty days, the machine is damaged in the middle, the fire tube is stopped for three days, and the formal research and development of the line protection tube takes more than one year.
