How to choose cutting? Installation knowledge of switch socket

How to choose the patch panel and what installation knowledge does the corresponding switch socket have? What I recommend to you today is the information of these two parts. Therefore, the plug-in should be designed according to the material contact or structure of the shell. Secondly, when installing a suitable switch socket, the corresponding tools should be prepared with reference to its specifications and models, and safe and suitable working conditions should be created as much as possible to achieve satisfactory results. The specific situation can be analyzed in detail or can be understood from the following. What we give you is a lot of knowledge.

First, how to choose a plug-in

1, look at the shell material first. The main switch brands in the market generally choose PC material, also called bulletproof glue. The characteristics of impact resistance, high temperature resistance and difficult discoloration are very important for controlling electrical switches. The front panel and rear base of a better switch are made of PC, but the general switch will use black nylon instead of PC on the base, which can reduce the cost a lot.

Also using PC material, many household products in Kai Guanchang are made in China (even if the standard is American GE, they are actually produced by domestic cooperative factories and only sold by GE). At present, in fact, no company in China has the ability to produce PC materials, and the so-called domestic products are generally reprocessed with recycled materials, so there are more impurities, which will be brittle and have obviously poor heat resistance. In order to reduce the cost, the bad switch may be replaced by mixture or ABS instead of PC material on the front panel. These materials are not only poor in impact resistance and heat resistance, but also easy to change color, and the surface is rough when touched too much.

2. Secondly, look at the contact point, which is the contact point of the conductive part in the switching process. Contact depends on size (bigger is better) and material. There are mainly three kinds of contacts, silver-nickel alloy, silver-cadmium alloy and pure silver. Silver-nickel alloy is an ideal contact material, which has good conductivity and hardness and is not easy to oxidize and rust. Silver-cadmium alloy contacts are also good in other aspects, but cadmium is a heavy metal, which is harmful to human body on the one hand, and its fusion with silver on the other hand is not ideal. Small cadmium particles will be formed on the contact surface, which may pull out the arc when conducting electricity. In fact, pure silver is not suitable for contacts, and its conductivity is really good, but it is soft and easy to oxidize (like silver jewelry will turn black after a long time). Soft texture, switch deformation contact more; If oxidation rusts, the conductivity will be much worse, and the rust spots will easily heat up and melt the contacts.

3. Third, look at the structure. Mainly large screen type, the appearance and feel are better than the previous thumb type. The biggest problem of thumb type is that it is easy to jam, because short torque, small switch action range and slightly light or hard spring may cause the switch to jam. I saw Gray (don't tell me it's American, if it's American, I'm a Martian) turn off a so-called reset switch the other day. Try to feel rough. I opened it and found a small roller inside. Press it and turn it 1/4 times. In order to reduce the inevitable friction, it was coated with lubricating oil. Imagine how to use the lubricating oil in this switch after half a year.

4. Look at the protective door. Poke one side of two holes and the bottom of three holes with a screwdriver or a small key. A little effort is to protect the door unilaterally, which means nothing. This kind of socket is obviously not safe enough.

Second, the switch socket installation knowledge

1, material requirements

(1) All kinds of switches: specifications and models must meet the design requirements and have product certificates.

(2) The types, specifications and models of all sockets must meet the design requirements and have product certificates.

(3) Plastic (table) board: it should have sufficient strength. Plastic (Taiwan) plate should be flat, without warping and deformation, and have product certificate.

(4) Wood (platform) board: its thickness should meet the design requirements and the provisions of the construction acceptance specification. Its board surface should be smooth, free from splitting and bending deformation, and the paint layer should be complete without falling off.

(5) Other materials: metal expansion bolts, plastic expansion pipes, galvanized wood screws, galvanized machine screws, wood bricks, etc.

2. Main machines and tools:

(1) red pencil, tape measure, spirit level, wire pendant, insulating gloves, tool bag, high stool, etc.

(2) Hammer, chisel, wire stripper, needle nose pliers, awl, tap, casing, electric drill, electric hammer, drill bit, nail gun, etc.

3. Fuck oak parts

(1) All kinds of pipelines and boxes have been laid. The box is tightly covered.

(2) The wire of the line has been worn, and the insulation shaking test has been completed.

(3) Interior decoration such as wall plastering, painting and wallpaper has been completed.

The above recommendations are suggestions on the selection of cuttings and the installation method of switch sockets. Therefore, first of all, it is necessary to design a suitable and reasonable plug-in according to the material, contact and structure of its shell, whether it is the details of the product or the overall gloss. In the installation process, professional tools should be prepared in advance according to different materials and specifications, and safe and reliable working conditions should be arranged to avoid potential hidden dangers caused by negligence.
