Use Case of Bending Type Pogo Pin

The Case of electronics cigarettes was one of the pretty many projects from a large manufacturer ChengBiao Company, requests as below:

No chamfer C0.2, surface roughness Ra0.8
Material, plunger/barrel was HBi59-1.5, Spring was SUS304,
Plating: plunger 10″ Au, barrel 4u” Au,
Rated voltage/current, 4.2VDC, 4A,
Spring force, 62.5g±7.5g,
Life cycle, more than 10,000 times.

Our R&D Engineer’s Designs

Based on the 4A current required by the customer, our preliminary proposal is to adopt the structure of the ball type, and the spring within the pogo pin must be insulated. according to the accurate shape of the electronic cigarette, the bending type pogo pin was recommended.

The Designs of Plunger + Ball + Spring

Because the rated voltage & current was 4.2V DC and 4A, our engineer adopted the structure of a ball and insulated spring to connect the plunger, so as to ensure all key components worked well in a range of 2.9V-5.4V and to ensure a stable power supply. the structure is very helpful for an electronic cigarette to provide a split-second high current.

The purpose of an insulated spring is to solve the problem when the plunger is separated from the barrel and the current is too large, it is easy to cause the spring to be burned by the high current and to further result in product failure. with the insulated spring, the product quality of electronic cigarettes will be first-class!

Design Introductions

The bottom of the barrel is bent after heat treatment. The soldering method is similar to how to solder through-hole spring-loaded pogo pin onto PCB. The positioning column at the bottom of the barrel is checked on the PCB and then fixed by soldering.

After bending, the height of the tail pin soldered to the PCB is very low, so it is very suitable for very thin products too. The disadvantage is that the product needs to be bent, and the cost is higher than the general pogo pin else.

Case Results

We detailedly designed product drawings, manufacturing technology processes, quality control processes, and so on, and all met customers’ targets including 4 Sigma with 99.62% FPY, daily capacity with more than 500,000 pcs per working day, etc.

What is BENDING Type Pogo Pin?

With the development of electronic technology and the upgrading of product technology, electronic products become more functional and occupy less space. In order to achieve narrow spacing, miniaturization, multi-polarization, and high reliability of products. Manufacturers began to research and develop high-end connector technology.

Pogo pin series pin connector with high density, small spacing, and diversified product structure has been applied in many industrial fields. Bending type pogo pin is used in consumer electronics, because of their special structural characteristics. Based on this design, it can change the height of space between two PCBs. Make electronic devices smaller.

Why the Bending type pogo pin is the best solution?

When the customer’s order quantity is relatively small, the cost of a customized stamping mold is relatively high. Because of the low cost of production materials, the bent Pogo pin has a simple structure and is easy to process. You can choose pogo pin connectors with low cost to meet production needs and reduce production costs.

What is the Material of Bending Type Pogo Pin?

Plungers and barres commonly used metal materials are:

Brass: C3604,C3601,C2680;
Phosphor Bronze: C5210, C5191, C5440;
Beryllium Copper: C17200, C17300;

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.
