TML tip is a device for creatingThe best contact of the device wires with the network. This marking is as follows. The letter "T" means that the part is made of a pipe, "M" is the name of the material, in this case it is copper. Brass or aluminum can also be used. Naturally, with the change of the source material, the marking will also change. The letter "L" means that the contact is tinned.
Any good host understands that simplethe connection of the home appliance to the network will not be enough to create acceptable conditions for the operation of the device. With poor contact, the wire will begin to experience overloads when applying voltage, which most likely will result in the failure of the entire device as a whole or even the ignition of the wiring. To avoid such trouble, you need to make sure the connection is secure. The TML tip is a special device that is designed to solve a specific problem. This is a special tip, which is used to terminate the electrical wire and thereby provide a reliable connection between the network and the device. There are several materials from which a tip can be made, but copper is considered to be the best.
There are two types of adaptation. The first type is the cable lugs that do not have a coating, and the latter are the tips that have a tinned coating.
Tinned tipped tips are considered the best species,than those that do not have a coating. They are more practical in use, since they provide sufficient corrosion protection, which, in turn, greatly increases the life of the device. In addition, the tinned contact exhibits resistance to such types of acids as sulfuric, nitric and hydrochloric. Another advantage is that such TML tips are not afraid of moisture, air, and any other aggressive manifestations of the environment. It is worth saying that due to this coverage the electrical conductivity of the device is still decreasing, however, even those that are available are considered stable and acceptable for operation.
End and crimping
Another important point in using thisdevices - is the protection of clean copper contacts, which quickly oxidize, because of what they lose their current conductivity, because of this, the resistance rises, which means that in this place they will begin to bask, and there will be a fire.
Copper tinned TML tips serve forendings of bare copper contacts. Most often, to install such a device on the veins of copper material, the usual crimping pliers are used. It should be noted that copper pipes with different diameters are used as a material for the production of these devices. They are cut, and then flattened to one side. After that, a small hole is made in the flattened end of the tube, which is necessary to tighten the bolt, which will hold the tip.
Crimping of TML tips is used for the following purposes:
- to establish a connection between the electrical network of the building and the necessary electrical appliance;
- To establish contact within one device between several parts or to establish communication between several devices;
- The "splicing" operation is very common, which is used when it is necessary to extend an existing wire by attaching another to it.
Tip with viewing window
One of the types of TML tip isTML (o). According to the main characteristics, these models are completely identical. As follows from their labeling, they are also made of copper, like the rest of the parts. The only and important difference from the standard elements was the presence of a viewing window. This hole, which allows you to ensure the correct connection of the contact, while the device is already worn on the wires. Most often, such varieties are used in industrial plants, and therefore not all electricians or masters of houses who need to connect wires know about the existence of such a small subspecies.
Bimetallic tip type
The type of cable lug TML can differ not only in the material from which it is made, but also in the manner of its installation, and also in its purpose.
The most universal part is considered to beelectrotechnical bimetallic detail. It has such advantages as the ability to connect to any kind of metal core, and also has a special small stopper, which allows you to pinch the wire on the required length. Most often for the manufacture of such devices used aluminum instead of copper.
Another type of this element is the TML tip of the ITC.
The most durable and reliable model iscopper blank. Very often it is made sealed, which makes it possible to install it in a humid environment. In addition, it has good resistance to any aggressive environmental influences. A cheaper and more accessible analogue of such a tip was brass.
It is important to note that copperbe installed only on the copper core of the cable. Another important nuance. Everyone who bought such details faced with a large number of digits on the package. For example, the tip of TML 6-6-4. Here it is important to note that all tin-plated elements can be installed on cables with a cross-sectional diameter of 2.5 to 240 mm2. The maximum voltage is up to 35 kV. But the numbers 6-6-4 mean the following: wire cross section - 6 mm2; diameter of the contact rod - 6 mm; the inner diameter of the shank is 4 mm.
There are several more types of various tips. To understand what is in a certain package, you need to understand the labeling.
- The TA marking indicates that the part is made of tubular aluminum.
- There is such a marking as CIP. It means that the cable tip is an isolated self-supporting connector with an annular mounting plate.
- The pin-like sleeve element will be referred to as the NRTI.
- A very common marking is the tip of TML-10. The figure 10 means that the wire cross-section and the diameter of the contact rod are 10 mm2 and 10 mm respectively.
There are 4 basic ways of mounting the tips. The first option is a crimping, the second is a screw or bolt, the third is a welding one, the fourth is a soldering of the tips.
If we talk about such a form of connection ascrimping, then it can be performed by four different tools. This can be a manual press, a mechanical, pumping or hydraulic press. Here it is important to understand that each of the devices has its own qualities and properties. For example, to press a household wire and a tip, it is best to use a conventional manual press. In order to connect the power cable and the tip between each other, you will have to use a more powerful tool. Most likely, you need a hydraulic or mechanical press.
One of the mounting options is bolt. In this case, the depth of the cable fixation in the part will be fixed by the bolt head. Before connecting these two elements together, it is necessary to clean the required length of the cable from the winding to expose the core. It should be noted that the press can have different sizes, which depend on the scope of the tool. However, the most popular in recent years are precisely those that can change their size as a swivel key. The parameters of the change range from 0.25 to 1 mm. Here there is one more important detail - it is the lack of the need to use pliers for work. The reason for this was that a manual press with these dimensions is most often used for crimping very thin cables that can break under the strong pressure exerted on it by pliers.
Currently the most popularthe tips are PHOENIX CONTACT. On the territory of the CIS, they are in greatest demand. Reviews about this product are usually positive. They keep on the cable pretty well. The connection between the cable and this part is also at an acceptable level, according to buyers. Some of the buyers used this part to reassemble the electrical contacts of the car engine. Owners say that even without a professional loader it is very convenient to do a crimping. You can do it with a hammer, but you need to beat carefully, otherwise you can kill the veins. At a current of about 80 A, the contacts remained cold.
However, it is not always possible to findthe size of the device. For this reason, quite often people make them themselves. It is quite easy to do this. In order to make such an element, you need to take a copper piece of pipe with a suitable size, flatten one end, and then make a hole with the desired size. However, the problem may be that it is not clear what voltage will be able to withstand such a product. Therefore, it is not recommended to do them yourself.
