Pogo pin is a kind of connector, its function is very simple, it plays the
role of an elastic connection. It can easily solve the board-to-board connection
in a small space. The pogo pin can be formulated according to the actual work
requirements, and different specifications can be selected during the
formulation. The following introduces the function and performance of the pogo
pin connector:
first,
The main function of the connector is the elastic connection. The pogo pin
can maintain a continuous and stable working current during the elastic
connection process, and the current is very small, only 3A, and it can reach 6A
in special cases. If the diameter is increased, it can be increased to 10A or
more. . Its working voltage is below 36 volts, its life can be more than 10,000
times, and it can exceed 1 million times in special cases, which plays an
important role in connection. Secondly, there are certain requirements in the
working environment of the pogo pin connector. The adaptable temperature when it
works is between -25 degrees and 75 degrees, and when it is in storage, the
temperature also changes, between -40 degrees and 85 degrees. between. And the
on-resistance is less than 30 milliohms. At present, the test method used by
Tyco Hanzer is the dynamic contact resistance in the working stroke. The pogo
pin connector has many advantages, such as: small contact resistance, high
working height of the product, low working height, low initial development cost,
large product current carrying, point-to-point contact, long life, etc. It has
been used by many large companies. Due to many large and low-end companies,
everyone has some one-sided understanding of pogo pin connectors, such as pogo
pins are prone to power failure, and the contact is unstable. In fact, as long
as the product design is reasonable and passes the dynamic resistance test, the
reliability of the product is very high.
Connector design Pogo pin articles
Overview of research and development of pogo pin connector: Definition of
.pogo pin connector (POGO PIN CONNECTOR): refers to the pogo pin connector used
in electronic signals and power supplies. The pogo pin connector is a signal
bridge, and its quality not only affects The reliability of current and signal
transmission will affect the overall quality of the entire electronic equipment
terminal.
.pogo pin connector type:
1 surface mount
Surface mount Pogo Pin connectors are mainly used in reflow soldering
process, which can improve soldering efficiency when used in large quantities,
and are the most common application method. The welding surface of this type of
product is flat, so the welding area is relatively large. The product is
packaged on tape and reel, and a process cap will be added if necessary, so that
the SMT robot can pick it up.
2 plugin classes
The plug-in type Pogo Pin connector is mainly used in wave soldering and
hand soldering process. This product can be positioned better than the patch
type. The tail pin of the product passes through the pcb board, of course, it is
more convenient for hand soldering. Products are usually in bulk.
3. Double pogo pin
This type of product is mainly used in special occasions, both ends cannot
be soldered, and can be easily separated. This type of product is not suitable
for roll packaging
4. Magnetic cable
A relatively new connection method, which uses a pogo pin connector and
then adds a magnet, can completely absorb the pogo pin end and the solid pin
through the attraction of the magnet to achieve the purpose of connection. Due
to the convenience of plugging and unplugging in this method, it can be
automatically separated after reaching a certain force, and the plugging and
unplugging life is long, regardless of the positive and negative sides. It has
been used only by Apple computer cables at first, and now it is a new type of
connection method adopted by many large companies.
