A pogo pin or spring-loaded pin is a type of electrical connector mechanism that is used in many modern electronic applications and in the electronics testing industry.[1] They are used for their improved durability over other electrical contacts, and the resilience of their electrical connection to mechanical shock and vibration.[2] The name pogo pin comes from the pin's resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection. This helical spring makes pogo pins unique, since most other types of pin mechanisms use a cantilever spring or expansion sleeve.[3] A complete connection path requires a mating receptacle for the pin to engage, which is termed a target or land. A pogo target consists of a flat or concave metal surface, which unlike the pins, has no moving parts. Targets may be separate components in the complete connector assembly, or in the case of printed circuit boards, simply a plated area of the board. Spring-loaded pins are precision parts fabricated with a turning and spinning process which does not require a mold, thus allowing the production of smaller quantities at a lower cost. Exploded diagram showing components of a standard pogo pin A basic spring-loaded pin consists of 3 main parts: a plunger, barrel, and spring.[2] When force is applied to the pin, the spring is compressed and the plunger moves inside the barrel. The shape of the barrel retains the plunger, stopping the spring from pushing it out when the pin is not locked in place. In the design of electrical contacts, a certain amount of friction is required to hold a connector in place and retain the contact finish. However, high friction is undesirable because it increases stress and wear on the contact springs and housings. Thus, a precise normal force, typically around 1 newton, is required to generate this friction.[3] Since a spring-loaded pin needs to have a slight gap between the plunger and barrel so that it can slide easily, momentary disconnections can happen when there is vibration or movement. In order to counter this, the plunger usually has a small tilt to ensure a continuous connection.[citation needed] Many manufacturers have created their own proprietary variations on this design, most commonly by varying the interface between the plunger and spring. For example, a ball may be added between the two components, or the plunger may have an angled or countersunk tip.[4][5] Various pogo pin designs The plunger and barrel of pogo pins usually use brass or copper as a base material on which a thin layer of nickel is applied. [6] As common in electrical connectors, manufacturers often apply a gold plating that improves the durability and contact resistance.[7] The springs are usually made of copper alloys or spring steel.[8][4] Some spring-loaded connectors, and the disassembled pogo pins inside them Spring-loaded connectors are used for a wide variety of applications, in both industrial and consumer electronics:
Connector arrangementWhen pogo pins are used in a connector, they are usually arranged in a dense array, connecting many individual nodes of two electrical circuits. They are commonly found in automatic test equipment in the form of a bed of nails, where they facilitate the rapid, reliable connection of the devices under test (DUTs).[10] In one extremely high-density configuration, the array takes the form of a ring containing hundreds or thousands of individual pogo pins; this device is sometimes referred to as a pogo tower.[citation needed] They can also be used for more permanent connections, for example, in the Cray-2 supercomputer.[11] When used in the highest-performance applications, pogo pins must be very carefully designed to allow not only high reliability across many mating/unmating cycles but also high-fidelity transmission of the electrical signals. The pins themselves must be hard, yet plated with a substance (such as gold) that provides for reliable contact. Within the body of the pin, the plunger must make good electrical contact with the body lest the higher-resistance spring carry the signal (along with the undesirable inductance that the spring represents). The design of pogo pins to be used in matched-impedance circuits is especially challenging; to maintain the correct characteristic impedance, the pins are sometimes arranged with one signal-carrying pin surrounded by four, five, or six grounded pins.[citation needed] Pogo pins connecting logic modules of the Cray-2 supercomputer Combination with magnetsSpring-loaded connectors may be combined with magnets to form a strong and reliable connection – a technique which has been employed extensively for consumer electronics such as 2-in-1 PCs and high-frequency data transfer.[12] One notable example of this is Apple's MagSafe connector.[13] Commercial productsAlthough often used as a generic name, pogo pin is a registered trademark of Everett Charles Technologies (ECT).[14]
Page 2A 2-in-1 PC, also known as convertible laptop, 2-in-1 tablet, 2-in-1 laptop, 2-in-1 detachable,[1] laplet,[2][3] tabtop, laptop tablet, or simply 2-in-1, is a portable computer that has features of both tablets and laptops.
Before the emergence of 2-in-1s and their denomination as such, technology journalists used the words convertible and hybrid to denominate pre-2-in-1 portable computers: Convertible typically denominated those that featured a mechanism to conceal the physical keyboard by sliding or rotating it behind the chassis, and hybrid those that featured a hot-pluggable, complementary, physical keyboard. Both pre-2-in-1 convertibles and hybrids were crossover devices that combined features of both tablets and laptops. The later 2-in-1 PCs comprise a category that is a sibling to both the pre-2-in-1 convertibles and hybrids. Models of 2-in-1 PC were each similarly denominated either a 2-in-1 convertible or 2-in-1 detachable, respectively, and despite borrowing the terminology of the pre-2-in-1 PCs, the two species of 2-in-1 PCs are distinct from the two species of pre-2-in-1 PCs because 2-in-1 PCs have additional features of traditional laptops. 2-in-1 PCs consist of portable computer components within light and thin chassis, and exemplify technological convergence. They are convenient for media consumption and non-intensive tasks in tablet mode yet useful for content production in laptop mode.[2] Sony VAIO Duo, an example of a 2-in-1 convertible with a sliding keyboard 2-in-1 convertibles are tablets with the ability to rotate, fold, or slide the keyboard behind the display. On most devices, the hinge is situated at the display and keyboard junction. However, the Dell XPS Duo is unique in that the display sits in a frame that allows the screen to be spun.[4] NetvertibleHP Compaq as netvertible example Rotational-convertible format is where in addition to the conventional hinging action, the central single hinge mechanism is also able to rotate about a central axis perpendicular to the keyboard surface, such that the laptop can be turned into a thick tablet. Most netvertibles have the option to support active (electromagnetic) stylus and/or touch screen (resistive or capacitive), some being ruggedized such as Panasonic Toughbook CF series. Other examples include Toshiba Portege M7xx, Fujitsu LifeBook T series and HP EliteBook Revolve series. 2-in-1 detachableHP Spectre x2, a modern 2-in-1 detachable 2-in-1 detachable are devices with detachable keyboards. In most cases, the keyboard part provides few, if any, additional features (most often a touchpad, as in the HP Spectre x2).[5] However, the keyboards of some detachable provide additional features similar to those of a docking station such as additional I/O-ports and supplementary batteries.[6] For instance, the Surface Book can leverage the discrete GPU in the keyboard upon the keyboard's connection.[7] When connected to the keyboard, the display of the detachable can either be free-standing on the hinge[8] or require external support, often in the form of a kickstand.[9][10] Novel ways of providing external support include the bending frame and locking mechanism of the HP Spectre x2.[citation needed] Though the keyboard is usually bundled with the purchase of a 2-in-1 detachable,[11][12][13][14] it is occasionally deemed an optional accessory by manufacturers in order to minimize the starting price of a device.[15] In such cases the 2-in-1 detachable is often displayed with its complementary keyboard in advertisements and promotional materials. This is true for all devices of the Surface and Surface Pro lines.[16][17][18] ThinkPad Yoga with 360° rotating hinge 2-in-1s fall in the category of hybrid or convertible tablets but are distinct in that they run a full-featured desktop operating system and have I/O ports typically found on laptops, such as USB and DisplayPort.[19][20][21] The most prominent element is the keyboard that allows the 2-in-1 to provide the ergonomic typing experience of a laptop. While 2-in-1s fall in a category distinct from laptops, they loosely parallel the traits of the Ultrabook device category, having light and thin chassis, power-efficient CPUs, and long battery lives.[22] They are distinguished from traditional Ultrabooks by the inclusion of a touchscreen display and a concealable or detachable keyboard. The Compaq Concerto, one of the earliest examples of a 2-in-1 PC. The earliest device that can be considered a 2-in-1 detachable is the Compaq Concerto from 1993. It came preinstalled with Windows 3.1 and Windows for Pen Computing, and had a cabled detachable keyboard, and battery powered stylus.[23] In June 1994, IBM introduced the ThinkPad 360P, which features a display that can be rotated backwards and closed down into a pen-operated tablet.[24] The IBM ThinkPad 360P was another early example of a 2-in-1. Shown here in tablet mode. Mainstream attention for 2-in-1 PCs was not achieved until nearly two decades later, when many manufactures showed devices, at that time referred to as "hybrid" devices, at CES 2011.[25] [26] While Packard Bell, Acer and HP all had Microsoft Windows based 2-in-1s by 2011,[27] Lenovo released the well reviewed[28] Windows 2-in-1: The X220 Tablet variant of the ThinkPad X220, successor of 2010's ThinkPad X201 Tablet. The 12-inch device included a digital stylus housed within the chassis, somewhat ruggedized construction, and a multi-touch screen with a twist and fold hinge.[29] Microsoft started its own line of 2-in-1s with the introduction of the Surface Pro series, the first of which was released in February 2013.[30] It had a 10.6-inch (27 cm) display, Intel Core i5 CPU, and included the Pro Pen stylus and a detachable keyboard that doubled as a protective screen cover. In 2015 Microsoft introduced the Surface Book series, which, similar to the Surface Pro series, features a detachable keyboard cover and Surface Pen stylus. Samsung entered the 2-in-1 PC market with the release of the Windows-based Samsung Galaxy TabPro S, which was released in March 2016.[31] It had a 12-inch display, Intel Core m3 CPU, a first-party keyboard attachment, and a TabPro Pen. Its successor, the Galaxy Book, was released in February 2017. Coming in a 10.6-inch model and a 12-inch model, the Galaxy Book has an improved detachable keyboard and include an S Pen.[32] Google entered the 2-in-1 market after it announced the Pixel Slate in October 2018.[33] It runs on Chrome OS and features a 12.3-inch display. It includes two USB-C ports, but it omits the headphone jack. The featured Pixel Keyboard and Pixelbook Pen are sold separately. Since 2012, a number of other prominent laptop manufacturers, such as Dell, Asus, and Sony have also begun releasing their own 2-in-1s.[2] While the iPad Pro has optional Smart Keyboard[34] and Apple Pencil accessories, Apple has yet to release a true 2-in-1 PC in a detachable form-factor and with a similar desktop OS, citing the quote below. In April 2012 Apple's CEO Tim Cook, answering to the question of the researcher Anthony Sacconaghi about a possible hybrid of iPad and MacBook, compared a 2-in-1 to a combination of "a toaster and a refrigerator" that "doesn’t please anyone":
2-in-1s are natively supported by the Microsoft Windows, and Google Chrome OS operating systems. Various other Linux distributions also support some touch features of 2-in-1s, though they are generally unsupported by hardware vendors.[36][37]
