Connectors play a very important role in electronic systems, and with the improvement of technology, the requirements for connectors are getting higher and higher, so the new design concept of connectors has also been widely concerned. Here are some innovative designs to inject some new air into the connector industry.

1. Double rods

In the connector series, the idea of two-bar design runs through the whole process. Imaginally speaking, the two-pole design can be described as "one arrow, two carvings". Optimized terminal design adapts to high-speed signal transmission and provides higher directional tolerance. In comparison of inductance, capacitance and impedance, two-pole terminals are smaller than box terminals in high-speed applications, and optimized to achieve minimum interruption. The two-bar design allows multiple connectors on a circuit board without plugging or short-circuit problems, and requires no large number of signals on a single connector. Simple wiring of two rods can save space, make the connector smaller, and simplify the inspection and measurement of welding pins. For example, put 12 on a board. It also reduces the cost of rework. Practical applications such as telecommunication end-user equipment, etc.

2. Bend pins at five depressions

Due to improper processing, traditional stamping will cause bending or deforming pins, and the bending process will cause capillary cracks, which is not desirable in terms of product long-term, and will also affect circuit performance and cost. ERNI adopts direct stamping of opposite bending angle. Stamping terminals can avoid capillary cracks caused by bending process and ensure complete electromechanical connection. The coplanarity of pins is 100% and controlled to tolerance (+0.05 mm). The coplanarity detection of 100% tab pins ensures the reliability of PCB assembly process, ensures good welding, improves product quality rate and reduces cost. It also improves the firmness of the right-angle connector and prevents the connector from being damaged due to improper operation. It is very appropriate to use the term "unbreakable". Especially suitable for inkjet printer controller, interface module interface and so on.

3. Surface paste with high retention force

For SMT products, it is generally believed that the retention of the board is very poor. Is the PCB holding force of the surface end-to-end connection lower than that of the through-hole end connection? The answer is: not necessarily. Through design improvement, the retention of PCB can be effectively improved. If the welding bracket, the hole (micro-hole) of the surface pin and the big welding pad are superimposed, the retention force can be improved. In fact, even I/O connectors can use surface-mounted pins. This can be imagined as "rooting on the ground". For example, the design of X-ray machine, ultrasonic scanner and robot Ethernet switch.

4. Reinforcement

It is necessary to determine the reliability of the connector, and allow the use of flat press tools. The plate is fixed on the outer shell to improve the firmness, achieve better manufacturing process and increase production. To sum up in one word is "rock-solid". Specific applications such as positron emission tomography scanner, embedded system of railway vehicles, etc.

5. Miniaturization

With the requirement of miniaturization of automotive electronics and consumer electronics, it is necessary to consider the design concept of high current and small spacing.

6. Locks

Connectors are designed with double locking to meet different requirements. Forward locking is designed for strong vibration applications. It is very suitable for automotive and subway applications. Friction locking is designed for general vibration applications. Double lock and double safety insurance ensures reliable connection, and special tools are not required for field dismantling (maintenance/replacement) cables. It is suitable for the design of monitor and LED lamp.
