Function and Material of Connector Housings

The connector housing provides many important functions, which can be understood in essence as the shell providing electrical insulation between adjacent contacts and between the contacts and the outside world. This insulation is usually expressed as the dielectric withstand voltage rating of the connector. So, do you know the specific functions of the connector housing?

What is the Function of Connector Housing?

1. Play a role in mechanical protection

The shell isolation separates the inside and outside of the connector and plays a role in mechanical protection. Especially for bumps, outdoor environments or the outside of electronic equipment, its sturdy shell can effectively resist the mechanical action of the outside world, thereby preventing the insulator and contacts from being damaged.

2. Waterproof and dustproof

The connector housings can protect the internal structure of the connector from external environmental factors such as dust and water. Especially for connectors used underwater or in the field, its shell also has a high sealing performance to varying degrees.

3. Play the role of supporting and installing insulators

When the insulator with contacts is installed on the connector housing, the contacts pass through the shell in the plug and socket to obtain a precise spatial position, thereby ensuring high precision of mutual matching.

4. Play the role of connecting and separating the plug and socket.

The connection, locking and separation of the connector plug and socket are achieved through the mechanical action between the shell parts. Its orientation and positioning require the cooperation of the shell.

5. It plays the role of installing and fixing the connector.

In the structural design of the connector, it is usually used to fix the connector on the panel or equipment.

6. It plays the role of fixing the cable.

When the flexible cable penetrates the rigid structure of the connector, it will swing and twist. The combination of the back cover of the connector housing and the clamping coil can make it tighter.

7. Combination of visual beauty and product function

The appearance of today's industrial connectors no longer only meets functional requirements, but also pays more attention to the combination of visual beauty and function.

PS: Welcome to inquire and order our A series connector housings and B series connector housings.

Connector housings can be made of various materials, and the specific material to be selected depends on the application scenario and the required performance requirements.

Common Connector Housings Materials and Features:

1. Plastic: Plastic connector housings usually have good insulation properties and low cost, and are suitable for some low-voltage, low-frequency application scenarios. Commonly used plastic materials include polyvinyl chloride (PVC), polyamide (PA), polypropylene (PP), etc.

2. Metal: Metal connector housings usually have high wear resistance, corrosion resistance and mechanical strength, and are suitable for some high-voltage, high-frequency, and high-speed transmission application scenarios. Commonly used metal materials include aluminum alloy, stainless steel, copper, etc.

3. Alloy: Alloy connector housings usually combine the advantages of metal and plastic, and have good mechanical properties and corrosion resistance. Commonly used alloy materials include zinc alloy, magnesium alloy, aluminum-magnesium alloy, etc.

4. Glass fiber reinforced plastic: Glass fiber reinforced plastic connector housings have excellent mechanical strength and corrosion resistance, and are suitable for some high-voltage, high-frequency application scenarios.
