What are the advantages and disadvantages of terminals


Terminal blocks can also be called "screw terminals", which are essentially a form of electrical interchange that can distribute power to your equipment. Terminals are commonly used in the automotive electrical field and are a routing tool that connects different circuits within a circuit and to each other.

The general wiring terminal is connected by stripping the wire insulation layer, winding it on the screw, and then fixing the screw in the terminal to achieve a connection, also called a screw connection. The second method is to solder the connector to the wire and connect it to the terminal, and connect the wire to the terminal. Usually in the car electric you will see the second method of connection, but there may still be some devices in the screw connection. The terminal blocks are designed for quick and simple connections, which can be quickly completed and quickly fixed.

Typically, a terminal block has two purposes, namely to connect different circuits together and to provide an electrical ground for the circuits. Of course, grounding provides a safe route for circuit termination, reducing the risk of short circuits within the system and causing serious injury to team members. Connecting different circuits can be a time-consuming task, making it easier to connect terminals, but for circuits that require more intense interaction, different technologies may be used.

The main advantage of the terminal block: The main advantage of the terminal block is cost. Compared with other types of connectors, the terminal block is relatively cheap. To some extent, it also saves time, because connecting wires is not a complicated process, and any terminal wire manufacturer with excellent technology can easily complete it.

The main disadvantage of the terminal: The main main disadvantage of the terminal is that in the presence of vibration or impact, the wire may loosen from the terminal, even if the connection is firm. Therefore, the device should test whether the connection is firm as much as possible before use to ensure that it can withstand the rigors it is in. Another potential disadvantage is the problem of space, because of their structure, the terminal blocks can only be so small.

When selecting a terminal, identify the requirements and understand the potential concerns. Most of the terminals are for a specific purpose, they are most suitable for use in the electrical field, terminals are very convenient, for the equipment to provide fast and efficient connection and circuit power distribution.

Development History and Trend of Connector Terminal Products

Terminal is one of the most widely used electronic components, widely used in computer, telecommunications, network communications, industrial electronics, transportation, aerospace, medical equipment and automotive industry and other fields.


What is the terminal

The function of the wiring terminal is well stated. The wiring terminal is actually a kind of connector. It is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends to insert wires. Screws are used to tighten or loosen, such as two wires, sometimes need to be connected, sometimes need to be disconnected, then they can be connected with terminals and disconnected at any time, without having to weld them or wrap them together, it's easy and quick.


Common faults and problems of terminals

From the perspective of use, the function that the terminal should achieve is that the contact part must be conducted and the contact is reliable. Insulated parts that should not be conducted must be insulated reliably.


How to detect terminal short circuit fault

The failure of the wire and the terminal may also be caused by a short circuit between the wire harness and the body (ground wire) or within the relevant switch. Before checking, first check whether the terminals of the body are firmly fixed, and then test according to the following steps.


How to Preventive Screening Check

In order to ensure the quality and reliability of the terminal and prevent the occurrence of the above-mentioned faults, it is recommended to study and formulate the corresponding screening technical requirements according to the technical conditions of the product, and carry out the following targeted reliability inspection for failure prevention.


What are the concepts of "connector", "connector" and "terminal?

Connectors, also known as connectors, plugs and sockets in China, generally refer to electrical connectors, that is, devices that connect two active devices to transmit current or signals (electrical signals or optical signals). Its function is very simple: it is blocked in the circuit. Or between isolated and disconnected circuits, a bridge of communication is built, so that current flows and the circuit realizes the intended function.
