Use Case of Bending Type Pogo Pin Connector

The case was describing a bending type pogo pin connector used in a precise ECG monitor from a famous medical equipment company HUAQIN Group, based on the customer’s requests.

ECG signals were collected from the left and right arms of people through special electrodes and sent to the signal conditioning circuit, as for the product which needed us to provide. It was to play the function of signal transmission.

Because of highly precisive medical equipment, the products provided by us needed to flow all medical standards and laws, including Medical Device Amendments Act, Council Directive 93/42/EEC on Medical Devices(MDD), and so on.

In this case, the rated voltage & current were 12VDC, 1.0A, the plating was Au, and the spring force was 85gf. the salt spray was 72 hours passed.

Studied Customer Requirements

To realize the function of the product, we designed a set of connectors consisting of four Pogo Pins. And considering the PCB space limitation, we designed the soldering foot into 90 degrees bending.

In order to improve the electrical performance and environmental resistance, these copper parts are plated with more than 5U” gold, and 50~120U” Nickel-plated as the base material to improve the wear resistance, We also coat insulation material on the spring surface, in order to improve the resistance value of the spring, so that the current does not transfer from the spring. we choose nylon as the housing’s raw material. It has good strength and high-temperature resistance. The connector’s rated voltage is 12V and the rated current is 1A. At the mating height, the force per each Pogo Pins is 100 gf±20gf.

Designs of Bending Type Pogo Pin Connector

In order to ensure that the four Pogo Pins can be solidly soldered on PCB, we press the four Pogo Pins into the housing holes. This not only ensures the distance between each Pogo Pin but also can be more efficient for SMT. In terms of the interference fit between Pogo Pins and the housing hole, we designed double convex ring interference to prevent Pogo Pins from falling off from the plastic holes, and the set of connectors is tightly attached to the PCB.

The plungers and barrels are turned by CAM, the surface is plated with gold with good electric conductivity and soldering performance, and then the plungers, barrels, and springs are assembled together by a special crimp machine to become a Pogo Pins. Pogo Pins are pressed into the holes of the housing with automatic equipment, and the surface of the barrel is pressed to the surface of the housing.

Because the soldering of the connector was a bending type, the tail pin of the bending connector was provided with a positioning bar. During soldering, the product is inserted into the positioning hole of the PCB. The connector was sodered firmly and there is no risk of deviation. with the tail pin of bend, it was very convenient for R&D engineers to select various product spaces.

When designing this product, it was very important to take care of the matching between the outer diameter of the chamfers and the diameter of the barrel. When a single pogo pin was installed into the housing, the interference force should not be too large or too small. If it is too large, the housing will crack, and if it is too small, the pin will be returned back or fall off.

What is a Bending Type Pogo Pin connector?

A bending type pogo pin connector is a connector that has a pin at each end, which can be bent to form an electrical connection. A pogo pin connector is a type of connector that may be used in a wide variety of applications, from consumer electronics to consumer goods, and medical and industrial equipment.

What is the Material of Bending Type Pogo Pin?

Plungers and barres commonly used metal materials are:

Laiton : C3604, C3601, C2680 ;
Bronze phosphoreux : C5210, C5191, C5440 ;
Cuivre-béryllium : C17200, C17300 ;
Cuivre-Tellure : C14500 ;
SUS304, SUS316F, SUS316L.

The main considerations for selecting the materials commonly used for Plunger and Barres are:

Commonly used copper alloy properties

Brass: The tensile strength of brass is 345~620MPa and the yield strength is 150MPa. It has an elongation of 5%. When brass needs to be bent, C3601 is usually selected for tempering to reduce its hardness. Brass has a minimum cutting performance of 90%. And brass has a conductivity of 26%. Brass is cheaper than other materials and is most commonly used.

Phosphor Bronze: The tensile strength of phosphor bronze is 700~800MPa and the yield strength is 600MPa. Its elastic modulus exceeds 110MPa. The hardness deformation space of phosphor bronze is large, ranging from HV170 to 210. Moreover, the electrical conductivity of phosphor bronze is 13%, which is worse than that of brass. Phosphor bronze has the advantages of high mechanical strength, high elasticity, impact resistance, and good toughness.

Beryllium copper: Beryllium copper has the highest tensile strength of 1100MPa among copper metals. Its yield strength is 520MPa. Its elastic modulus exceeds 135MPa. The hardness of Beryllium copper is between HV380 and 440. Beryllium copper has excellent electrical properties with conductivity up to 45% when heat treated. Beryllium copper has the advantage of high mechanical strength and can be strengthened after treatment. But materials are relatively expensive.

Tellurium copper: Tellurium copper has a tensile strength of 330MPa and a yield strength of 275MPa. Tellurium copper has a hardness of HV100. Tellurium copper reaches 15% in elongation and 85% in turning performance.

Tellurium copper has the highest conductivity among these copper metals, up to 85%~93%, with excellent electrical characteristics. Tellurium copper alloy is the best cutting material among high copper alloys, with excellent electrical conductivity, thermal conductivity, corrosion resistance, and high-temperature resistance.
