How many types of terminals are there and what they look like

There are many types of terminals, including: terminal blocks.

Ring Ground Terminal, Buckle Terminal, Locking Terminal, Sheath Terminal, Semi-Insulated Terminal, Spring Terminal, Stainless Steel Terminal, U-Terminal, Fuse Terminal, Straight Terminal, Self-Locking Terminal, Right Angle Terminal, Shark Tooth Terminal, Crimping Terminal, Plum Terminal, Sun Terminal, Ring Terminal, Square Terminal, Fully Insulated Terminal, Insulated Cold-pressed Terminal, Round Terminal, Ear Terminal, Blade Terminal, Fork Insulated Terminal, etc., the shape of the respective terminal is shown in the figure.

Terminal blocks. It is a kind of accessory product used to realize electrical connection, which is divided into the category of connectors in the industry. With the increasing degree of industrial automation and the increasingly strict and accurate requirements of industrial control, the amount of terminal blocks is gradually increasing.

With the development of the electronics industry, the range of use of terminal blocks is increasing, and the variety is also increasing. In addition to PCB board terminals, the most widely used are hardware terminals and nuts.

terminals, spring terminals, etc. There are many types of terminals, including: terminal blocks, ring ground terminals, buckle terminals, locking terminals, sheath terminals, semi-insulated terminals, spring terminals, stainless steel terminals, U-terminals, fuse terminals, straight terminals, self-locking terminals, right-angle terminals, shark tooth terminals, crimping terminals, plum terminals, sun terminals, ring terminals, square terminals, fully insulated terminals, insulated cold-pressed terminals, round terminals, ear pick terminals, blade terminals, fork terminals, etc., each terminal shape.

First, the spacing is different.

1. pH: The distance between the terminal pin and the pin is 2 00 mm.

2. EH: EH means that the distance between the terminal pin and the pin is 2 50 mm.

3. XH: The distance between the terminal pin and the pin is 2 50 mm.

4. zh: The distance between the terminal pin and the pin is 1 50 millimeters of Lu Lao grip meter.

Second, the materials are different.

1. PH: The material of PH is metal phosphor bronze.

2. EH: The material of EH is metal tin.

3. XH: The material of XH is metal tin.

4. The material is PA66UL94V 2 resin.

Third, the maximum contact resistance is different.

1. pH: The maximum contact resistance is 25m.

2. EH: The maximum contact resistance of EH is 20.

3. XH: The maximum contact resistance of XH is 20.

4. The maximum contact resistance of zh:zh is 30m.

Terminal blocks can be divided into many kinds in the industry, European terminal series, plug-in terminal series, fence terminal series, spring terminal series, track terminal series, wall terminal series, Japanese combined terminal, European frame pressure combination terminal, spring terminal and circuit board PCB terminal. Various types such as circuit board connectors. Production of high-current, heavy-duty outlets.

CNC machine tools, electronic handwheels, etc., I hope it will help you.

The terminal can also be referred to as a wire harness.

There are many types of terminals, and there are different ways to detect them.

From a macro point of view, it can be roughly divided into two categories, automotive wiring harness and electrical wiring harness.

From the crimping process, it can be divided into puncture terminals, plug-in terminals, connector terminals, flag terminals, etc.

It can also be classified according to the square size of the core, which can be divided into several lines, No. 1 and No. 2. Wait.

Common terminal types are: 110 terminals, 187 terminals, terminal blocks, cold-pressed terminals, ring terminals, ground ring terminals, plum terminals, lock terminals, in-line terminals, flag terminals, male and female terminals, male terminals, female terminals, spring terminals, sheath terminals, crimping terminals, flag terminals, straight terminals, insulated cold-pressed terminals, 250 terminals, terminals, terminals, etc., 110 terminals, connecting terminals, ring terminals, ground ring terminals Their role is to connect electrical signals and conduction, They are used in different fields, but they are all used in electronic connectors, so the terminals are very important.

There are too many types of terminals, and different brands have different terminals.

The stability of the terminals is not the same with different contact plating.

It's the simplest shape, not all of them are the same, there are socket types, and there are pin-type Qiao's --- Sun Gong.

The terminals are used with wire diameters up to XH, VH, SAN, SCN

These are not clear, but it is estimated that they are the names of the terminal series of each manufacturer. Not a generic series for the industry.

PCB terminals, terminal blocks are well understood.

The solder on the PCB board is the PCB terminal, and the one that is plugged into him is generally the terminal block of the connected wire.

In layman's terms, there are terminals on the board and terminals on the wire, and after the two terminals are plugged in, the PCB board and the wire are turned on.

There is also a relay terminal, which is used when the wire is connected to the wire, which is called the relay terminal.

General terminal: for the connection of wires at both ends of a circuit, it is the most used terminal;

Connecting terminals: through the middle gap in the upper part of the insulating seat, connect the two terminals together with a conductive sheet, so that various circuits are parallel or separated;

Test terminal: used to access the circuit of the current transformer, it can be connected to the test instrument without loosening the original wiring, so as to ensure that the secondary side of the current transformer will not open the circuit during the working process;

Connecting test terminal: it has the function of both test terminal and connecting terminal;

Special terminals: for connection terminals that require easy disconnection circuits;

Terminal terminals: Terminals used to secure or separate different mounting units.

The role of the terminal:

Terminal block: It is composed of various types of terminal blocks.

When the in-screen equipment is connected with the off-screen equipment and the small bus at the top of the screen, it must pass through the terminal strip;

When devices from different installation units in the same screen are connected to each other, they also need to go through the terminal strip.

Terminal blocks, generally speaking, are accessories used to realize electrical connections.

Terminal block type

As far as the current market is concerned, the terminal block can be divided into: European terminal block series, plug-in terminal series, transformer terminal block, spring terminal series, rail terminal series, etc.
