Information

This standard is equivalent to the international standard IEC455 (1988) General Rules for the Identification and Application of Alphanumeric Systems for Equipment Terminal Blocks and Specific Conductor Terminals.

Subject Content

This standard specifies various methods for identifying terminals of electrical equipment (hereinafter referred to as equipment), and formulates a general rule for identifying equipment terminals and specific wire terminals with an alphanumeric system. This standard is applicable to the identification of terminal blocks of equipment (such as resistors, fuses, relays, contactors, transformers, rotating motors, etc.) and combinations of these equipment, as well as the identification of specific wire ends. If necessary, the detailed application of these general rules to some products and the necessary auxiliary identification methods can be given in the relevant standards.

recognition methods

One or more methods can be used to identify equipment terminals and specific wire terminals: a. The marking system of related products can be used to determine and identify the actual or relative position of equipment terminals or specific wire terminals; b. Use the marking system of relevant products to determine and identify the color marking of equipment terminal blocks and specific wire terminals; c. Graphical symbols specified in GB5465 shall be adopted. If auxiliary symbols are required, they shall be consistent with the figures in GB4728; d. The alphanumeric symbols specified in Chapter 5 of this standard shall be used.

Basic structure of switch 2022-11-22 17:52:00
The diode in parallel on the relay plays a protective role to prevent the crystal triode from being damaged due to high voltage generated by self induction when the relay is powered off and released. Component specification: J relay 4098 operating voltage 6V V1V2 crystal triode 9014 VD crystal diode 2CP10 or 1N4001 R adjustable resistor 100k C electrolytic capacitor 100u/6V K1 button switch. The simplest switch has two pieces of metal called "contacts". When the two contacts contact, the current will form a loop. When the two contacts do not contact, the current will open. When selecting contact metal, the degree of corrosion resistance shall be considered, because most metals will form insulating oxides after oxidation, making the contact unable to work normally. Factors such as conductivity, hardness, mechanical strength, cost and toxicity shall also be considered when selecting contact metal. Corrosion resistant metals are sometimes plated on the contacts. Generally, it will be plated on the contact surface of the contact to avoid affecting its performance due to oxides. Sometimes non-metallic conductive materials, such as conductive plastics, are used on the contact surface. In addition to the contacts, there will also be movable parts to make the contacts conductive or non conductive. The switches can be divided into toggle switch, key switch, Rocker switch, etc. according to the different movable parts, and the movable parts can also be other types of mechanical links.
Main classification of switches 2022-11-22 17:51:00
Classification according to use: fluctuation switch, band switch, recording and playing switch, power switch, preselection switch, limit switch, control switch, transfer switch, disconnector, travel switch, wall switch, intelligent fire switch, etc. Classification according to structure: microswitch, ship type switch, button switch, toggle switch, button switch, key switch, as well as fashionable membrane switch and point switch. Classification according to contact type: switches can be divided into three types according to contact type: a type contact, b type contact and c type contact. The contact type refers to the relationship between the operating condition of "the contact closes after operating (pressing) the switch" and the contact state. The switch with appropriate contact type shall be selected according to the application. Classification according to the number of switches: single control switch, double control switch, multi control switch, dimming switch, speed regulating switch, splash box, doorbell switch, inductive switch, touch switch, remote control switch, intelligent switch, card plug-in power switch, and special switch for Yuba.

Basic introduction of terminals 2022-11-22 17:49:00
In the project, it is the interface reserved by the pre station project for the post station project and the embedded facility of the post station interface project. The terminal section inspection microscope can produce upright three-dimensional space image when observing objects, with strong stereoscopic sense, clear and wide imaging, and long working distance; It is equipped with a high-precision harness terminal image measurement and analysis system, which is combined into a harness terminal detection microscope. The perfect combination of high-quality optical system and high-resolution camera makes the section image clearer, and the unique multiple and fixed file makes the measurement more accurate. The terminals are the components that connect the battery to the external conductors. In electrotechnics, terminals refer to wiring terminals, also called wiring terminals, which are classified into single hole, double hole, socket, hook, etc., and materials, including copper silver plating, copper zinc plating, copper, aluminum, iron, etc. Their function is mainly to transmit electrical signals or conduct electricity. To check whether the terminal voltage is good or not, professional testing equipment is required.
Basic performance of connector 2022-11-22 17:47:00
The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability index, which is called mechanical operation in the national standard GB5095. It takes one insertion and one extraction as a cycle, and takes whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and extraction cycle as the judgment basis. 1. Mechanical property As far as the connection function is concerned, the insertion and extraction force is an important mechanical property. Insertion and pull-out force is divided into insertion force and pull-out force (pull-out force is also called separation force), and their requirements are different. There are provisions on maximum insertion force and minimum separation force in the relevant standards, which shows that from the perspective of use, the insertion force is small (so there are structures with low insertion force LIF and no insertion force ZIF), and if the separation force is too small, the contact reliability will be affected. The insertion and withdrawal force and mechanical life of the connector are related to the contact structure (positive pressure), the coating quality of the contact part (sliding friction coefficient) and the dimensional accuracy (alignment) of the contact arrangement.
