Insulation piercing connectors

In order to keeps electrical and mechanical performance of insulation piercing connectors, designers focus on connector structure and material, etc.

Outer shell is made of high quality engineering plastics, so the connector is rugged.

Inner contact material is copper alloy with silver plating, which can withstand high current and suitable for copper-aluminum transition.

Sealing ring can with below functions, anti-moisture, UV resistance, suitable for different temperature and anti-corrosion.

Locking component is designed after calculate strength, when with proper piercing strength, torque nut will be off automatically.

Advantages:

1.       easy to mount

2.       no need remove cable insulating layer, cut main cable

3.       Water-proof

4.       socket wrench are only needed when doing cable assembly

5.       safe for use

6.       Anti-vibration, water-proof, anti-corrosion, etc.

7.       Save cost

Automotive connector design requirements

There are about 1500 connections in one light-vehicle, 50% to 60% connections is for distribution functions.

Automotive connectors are applied to harsh environment, such as -40^oC to 155^oC operating temperature, vibration, oxidation, friction and corrosion, etc; it increased difficulty of connector design.

In order to ensure the connection, we need pay attention to below factors when designing except meeting the standard of USCAR-20;

1.       Good interconnect performance

2.       Stable normal forces

3.       Steady current and voltage

4.       Robustness

5.       Suitable for harsh environment application

6.       Insertion force <20.5kg

7.       Retention force >2.5kg

8.       Operating temperature -40^oC to 120^oC

Connector designers also need find and analyze the physical and mechanical phenomena which will affect connector performance, evaluating connector stability with precision test according to automotive manufacturers’ application and performance requirements.

The Basic Knowledge of Automobile Connectors

The connector is commonly-used electric device, it plays the role of circuits connection, and its types can be divided into network connector, optical fiber connector and industrial connector etc., here let’s get to know about some basic knowledge of automobile connectors.

The automobile connector is mainly used in the electronic engineering technology, it is simple but very important, it connects the isolated circuits and keep them clear and energized. The automobile connector consist of four parts, contact, insulator, accessory and shell.

A car needs thousands types of connectors, with the continuous improvement of living standards, people require higher for car, such as the comfort, safety and environmental protection, therefore the relative electric products are increasing, and the automobile connectors are increasing accordingly.

Thought automobile connector is small in appearance, it is very important, if a connector lacks, the car can’t operate well even stop to work, so the protection for connectors as important as the maintenance for maintenance ,we must pay enough attention for this.

Choose the right industrial connector

The whole equipment’s performance will be influenced by a small connector, so a right connector is absolutely vital, how to choose the right industrial connector? Below are the key points we should pay attention to;

1. Connector type -It is decided by applications, whether the hermetic sealed need be enhanced or back shell shall be added is upon to the application environment, termination type and contacts no. is chosen according to connector type and spec.

2. Electric property -Rated current, voltage, contact resistance, insulation resistance, dielectric strength, VSWR, EMI shielding effectiveness, etc shall be considered when choosing industrial connectors.

3. Application environment –Humidity and temperature are the main factors. For harsh environment, shock, vibration, production environment (such as temperature for solder, how long it will be taken) also need be noted when choosing connectors.

4. Mechanical requirements –dimension, insertion and extraction force, life time, footprint are very important for choosing the right connectors. For example, PCB layout tolerance is significant for connectors with PCB termination.
