What Is a Pogo Pin Connector?

 

A pogo pin connector is a spring-loaded electrical connector. These connectors are used in a variety of modern electronic applications. They are also common in the electronics testing industry. This article discusses the basic characteristics of the connector. In addition, you'll learn about the reversible insulative sleeve and the conductive terminal.

a spring-loaded pin

The spring-loaded type of connector creates a clean and reliable electrical contact between two components. This type of connector is used in mobile devices to recharge rechargeable batteries. The spring-loaded connectors compensate for uneven surfaces and different heights, ensuring a perfect electrical contact. The spring-loaded type of connector is ideal for rugged and demanding applications.

A spring-loaded pogo pin connector consists of a Plunger, a Tube, and a Spring. The needle is usually beveled to maximize the spring force applied to it, thereby maintaining stable contact with the inner wall of the Tube. The gold-plated needle and the tube provide a low contact impedance, which ensures a stable connection.

a conductive terminal

A conductive terminal for a pogo pin connector is a device that has a slot in its bottom wall for receiving a conductive terminal. The slot is defined by a ring protrusion disposed near the bottom of the pogo-pin terminal. The ring protrusion engages with the conductive terminal to transmit the electrical signals.

The conductive terminal is used to provide a complete connection path to complete the circuit. In pogo connectors, the conductive terminal is a flat or concave metal surface. The target can be a separate component in the connector assembly or a plated area on the board. Some designs incorporate a spring-loaded pin that is precision-machined and does not require a mold. This allows for smaller quantities of connectors at a lower cost.

a reversible insulative sleeve

An insulative sleeve for a pogo-pin connector includes a reversible insulating section that is fastened at the bottom end of the pogo-pin terminal. This insulating section accommodates the pogo-pin terminal, with its conductive terminals located above. The insulative section includes a groove defined inwardly and engages with the ring protrusion 22.

The insulative sleeve has the advantage of ensuring that conductive liquid cannot seep into the connector cradle. This means that pogo-pin connectors can be used in applications where high current capabilities are required. Some medical devices require high-current carrying capacity. With the help of the advanced insulator technology, pogo-pin connectors can carry up to 10 Amps, far exceeding the current capacities of standard ball connectors.

a movable protrusion

A pogo pin is a type of connector having movable protrusions that are attached to an inner shield and form electrical connections between the contacts. The movable protrusion is typically located on the bottom side of the connector. These protrusions are arranged in a staggered configuration. This arrangement can accommodate different types of sensors, allowing one connector 200 to accommodate a wide variety of sensors.

The movable protrusion on a standard pogo pin connector is a movable protrusion that is located between the inner shield 600 and printed circuit board 500. The protrusion is usually cylindrical in shape, and its distal end is formed with a plurality of electrical contacts. These contacts engage with contact tips 1170 of the plurality of pogo pins 1000.

a recess for a conductive sleeve

A recess for a conductive or insulative sleeve on a pojo pin connector protects the air gap between two devices. It is typically a ring-shaped protrusion at the bottom of the pogo-pin terminal. A conductive terminal abuts against the insulative sleeve.

The sleeve is disposed over the socket pin's end and features radially-inward-extending prongs that extend into the socket pin's hollow. The sleeve is designed to accommodate the receptacle for signal lead 16 on an IC device.

a corresponding pogo-pin terminal

A pogo-pin connector usually includes an insulated housing and a metallic pogo pin. When the connector is closed, the pogo pin contacts the electrical contacts on one side and the base contacts the other side. When the electrical plug is inserted, the contact portion of the pogo pin pushes against the base, and the compression spring moves the electrical plug along its length.

This is a mechanically locking feature that ensures the sensor is fully inserted. The sensor is positioned on the receiver 400a and is pushed downward by the key detent 865a. This mechanical locking feature provides a tactile feel when the sensor is properly inserted.
