Terminal blocks with business in the selected terminal products, often taking into account the sliding filament of terminal. Terminal R & D qualified would consider this problem in the development of products at the beginning, but there are still many manufacturers due to lack of funds, outsourcing screw not carefully chosen, causes the product qualified rate is not high, and missed opportunities for cooperation. Elinker Electric Co. Ltd. as a terminal R & D business professional, has a strict quality management standards, in the production process of each parts in the strict quality control, its purpose is to provide the best quality products for customers.
The following Elinker Electric technical staff on the screw from sliding problem specific analysis:
Sliding / slippery silk "is threaded connection, threaded joints caused by excessive force or other reasons cause the screw tooth wear and the thread can not bite, the thread connection is not tight. Analysis of the screw "sliding" from the angle of physics, there are several reasons: one is too hard or too partial; two is the device of excessive wear; three is the material quality is too poor.
The common solution:
1, with a hard object stuck in the slippery silk edge, and then slowly unscrew the screwdriver, corresponding clip corresponding to slowly upward, so that the line!
2, in daily life, we always come into contact with the screw, such as bicycles, electric fans, hair dryer and other appliances. But if a long time, the screw (nut) often rust, sometimes is the wrench to screw cannot open. Then how to do?
(1) for a rusty screw shock:], do not use a wrench hard twist, to prevent the six angular sliding screw screw screw screw wrench, wring or bad. At this time, the handle can be gently shaking hammer wrench, general rusty screw can shake unscrew.
(2): top hammer knock with edge, nut tapping corrosion, it is easy to make the nut loose. For example, two bicycle pedal fixed bolt nut, according to the pedal plate thickness, metal structure, control of force on the nut. The hard nut of iron slightly larger, plastic to tap. If still does not work, with a hammer along the direction in tapping nut, you can easily remove nut.
(3) burning: some screw rust is very serious, with the above methods do not work, you can use "fire attack". With gas oxidizing flame put the screw, nut fully barbecue, and then to the red screw a oil drop. The heating screw is designed to make the screw heat expansion. Drop of oil is designed to make screw cold shrinking rapidly, increasing the clearance between the screw rod and the nut, the oil flows into the nut can be screwed down after. But if there is a plastic device with the nearby.
(4) impulse: screw top corrosion form some device, can not use wrenches, pliers discharge, can impact method. First with a hammer and a flat screwdriver to screw the top vertical impact a V slot, then, adjust the punching cone angle, impact along the screw's direction, see figure 2. Stay loose, available pliers will screw up. "A" or "ten" word screw slippery mouth, also can use this method, combined with the pliers screw out screw.
(5) welding: removing device, It is often seen. twist off screw situation. On the roof of the screw, generally do not use electric drill, because a little carelessness will bad drilling screw hole. The better way is to use welding welding wire breaking a long iron. Iron cross section by screw diameter is. As shown in figure 3. Put the iron weld after welding, quickly to drop into the oil, the oil infiltration nut. After cooling, with a small iron along the horizontal direction and the other end of the cone on the block, the screw loosening, rotating block, which can spin out the broken wire.
Terminal R & D Elinker Electric has been committed to the high quality, our company terminal screws required for most by Elinker electric independent production, in the process of using the terminal quality guarantee.
