Terminal wire harnesses type and description


Terminals are crucial components to any cable assembly and wire harness process.   By definition, a terminal is part of a class of electrical connectors used for the transfer of electrical currents from a grounding source or power.   The terminal of a wire or cable also indicates the point at which the conductor, from a component, device, or network, comes to an end.   The multitude of cable applications introduces a wide selection of terminal variations and types.   Each project consists of specified requirements that lead to the use of some terminals over others.   SAISONIC supplies customers will all kinds of terminals harness , effectively integrating the necessary parts for a successful cable assembly!

There are two main combinations in cable terminals: insulated and non-insulated.

According to the specified cable assembly project, either of the two variants is the preferred choice for high-quality product performance.

1.Insulation provides an additional protective cover to prevent water and other moisture from entering the wires. Insulating materials can be nylon, heat-shrinkable materials or vinyl materials, serving as non-conductive wires.

2. Non-insulating is usually used when no additional wire protection is required. In addition, non-insulated wires have a lower manufacturing cost and thus prove to be more economically valuable.

 

Terminal type

1. Ring terminal

 

A circular terminal on which screws or studs can be easily fixed. 

The circular terminals are either crimped or welded to the wires. 

There are two types: insulated and non-insulated.

Common applications: Ring terminals are typically used in the automotive industry. 

This shape is highly suitable for connecting various contactors or mechanical relays to automotive engines and circuits.

 

 

2. Fork terminal  (Spade)

An open shovel terminal for convenient use, allowing for easy connection or removal from screws. 

There are two types: insulated and non-insulated.

Common applications: Wire harness assembly projects are usually composed of closely spaced installation Spaces, so shovel terminals are mostly used. The shovel provides reliable and fast weld-free electrical connection.

 

 

3. Hook terminal

A kind of terminal that is convenient to use and has an open end. 

The produced insulated or non-insulated hook structures provide simple and durable connections for various projects.

Common applications: The simple hook design allows for an easy-to-use terminal that is durable and efficient. 

Therefore, examples that require wire connectors are the most common hook terminal applications.

 

 

 

4. Quick disconnection terminal

The quick disconnection terminal provides convenient and reliable use, offering a simple connection and disconnection of two wires. Produce insulating or non-insulating products.

Common applications: Quick disconnection terminals can be found in a wide range of automotive, industrial and consumer products. 

As one of the fastest ways to connect and disconnect two wires, this terminal is easy to reuse and highly efficient.

 

 

5. Bullet terminal

The bullet terminal is connected to the male connector and the open circular female connector to form a high-quality connection. 

The connection with the bullet terminal helps prevent corrosion and other potentially harmful substances from entering the wire harness.

Common application: In the automotive industry, bullet heads are used for quick and simple wiring connections. 

The bullet design provides a durable connection that can be easily assembled and disassembled during the manufacturing process.

 

 

6. Butt terminal

The butt terminal connects or terminates a single or multiple wires. They help prevent wear and tear and cutting. This additional protection helps prevent moisture, corrosion and other negative factors. The butt terminal is a simple solution for extending wires because it can match and connect wires.

Common application: In various industries, butt terminals safely terminate any given wire. In addition, another common use is to connect one wire to another.

 

 

7. Flag terminal

Terminals that provide convenient and secure connections. The marking terminal works well in narrow Spaces and when the quick disconnection is too large. Provide quick and convenient connection and disconnection. There are also two types: insulated and non-insulated. For example, 187,110,205,250

Common applications: In applications that require frequent connections, enhance the reliability of the terminal.
