twitter announced today that it will be removing its implementation of stories dubbed “fleets.” the feature was either loved or hated by twitter users since its initial release last year.
this short-lived feature, which was released in november of last year, will be removed on august 3. twitter acknowledged the controversial nature of the snapchat/instagram clone with the farewell tweet. notably, there was no fleet from the main twitter account announcing the departure of the feature, only a standard tweet.
in the goodbye, the company said it is working on “new stuff.” one can hope that they add the ability to edit tweets, in addition to the new edit audience and monetization features.
in a more detailed blog post, twitter shared that it hoped fleets would make people more comfortable posting onto twitter. as fleets disappear, some of the fleet creation features, like gifs and stickers, will be implemented into the standard tweets composer.

Coaxial power connector
A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity. Also known as barrel connectors, concentric barrel connectors or tip connectors, these small cylindrical connectors come in an enormous variety of sizes.
Barrel plug connectors are commonly used to interface the secondary side of a power supply with the device. Some of these jacks contain a normally closed switch; the switch can disconnect internal batteries whenever the external power supply is connected.
Connector construction and terminology
The connector pairs for barrel connectors are defined in terms of "plugs" and "receptacles"; receptacles are more commonly called "sockets" or "jacks" in the United States. Receptacles may be panel-mounted or circuit board-mounted. Plugs are on cables. Some in-line receptacles are also cable-mounted.
Power is generally supplied by a plug to a receptacle. Cables are available with one in-line receptacle fanning out to a number of plugs, so that many devices may be supplied by one supply. As the use of a plug implies a cable, even a short stub, some power supplies carry panel-mounted receptacles instead to avoid this cable. Cables for such cases are available with a plug at each end, although cables or adapters with two receptacles are not widely available.
On the plug, the outer body is metallic and cylindrical in shape, and comprises one of the two contacts. The second, inside contact is a hollow metallic cylinder constructed to accept insertion of the pin in the corresponding socket. The inner and outer barrels are separated by an insulating layer, which is flared at the tip to prevent a short circuit when the plug is inserted or removed.
Socket or receptacle
There is typically a single spring-loaded contact at the side of the socket and a pin in the center.
There are many different sizes of coaxial power connectors. See the table at the end of this article.
Contact ratings commonly vary from unspecified up to 5 A (11 A for special high-power versions). Voltage is often unspecified, but may be up to 48 V with 12 V typical. The smaller types usually have lower current and voltage ratings.
It is quite possible that new sizes will continue to appear and disappear. One possible reason that a particular manufacturer may use a new size is to discourage use of third-party power supplies, either for technical reasons or to force use of their own accessories, or both.
The sizes and shapes of connectors do not consistently correspond to the same power specifications across manufacturers and models. Two connectors from different manufacturers with different sizes could potentially be attached to power supplies with the same voltage and current. Alternatively, connectors of the same size can be part of power supplies with different voltages and currents. Use of the wrong power supply may cause severe equipment damage, or even fire.
Common sizes and interchangeability
Generic plugs are often described by their inside diameter, such as 2.1 mm DC plugs and 2.5 mm DC (direct current) plugs.
After the two common 5.5 mm OD (Outer Diameter) plugs, the next-most common size is 3.5 mm OD with a 1.3 mm ID (Inner Diameter), usually about 9.5 mm in length, although both longer and shorter versions also exist. These 3.5 mm OD plugs are normally used for lower voltages and currents.
Locking and retention features
A ring-shaped "locking detent" or "high-retention feature", present on the barrel of some DC coaxial connectors, is a feature intended to prevent accidental disconnection. Typically, this feature is a conical cut-back section of the tip, just behind the insulator that separates the inner from outer contact surfaces.
A "lock-ring DC coaxial connector" uses a captive threaded ring or collar to secure the connection between the plug and jack. This design offers strong resistance to unplugging when used properly.
A "lock-tab DC coaxial connector" (also called "bayonet lock") offers a compromise that resists unplugging, but which will disengage when pulled hard enough. This connector uses small metal tab protrusions on the connector barrel to lock the plug in place, requiring a special push-and-rotate motion to engage the locks.
There are several standards in existence, provided by bodies such as the IEC, EIAJ in Japan and DIN in Germany. More recently, some manufacturers appear to have implemented their own system correlating voltage and plug size. In addition, there appears to be a trend to standardize DC connector to negative barrel (or sleeve) of a coaxial power connector.
IEC 60130-10:1971 defines five DC power connectors.
- Type A: 5.5 mm OD, 2.1 mm ID (with optional screw lock)
- Type A: 5.5 mm OD, 2.5 mm ID (with optional screw lock)
- Type B: 6.0 mm OD, 2.1 mm ID
- Type B: 6.0 mm OD, 2.5 mm ID
- Type C: 3.8 mm OD, 1.1 mm ID
- Type D: 6.3 mm OD, 3.1 mm ID
- Type E: 3.4 mm OD, 1.3 mm ID
EIAJ power connectors
Further information: EIAJ connector
Five plug and matching socket or jack designs are defined by the EIAJ standard RC-5320A (also called JEITA RC-5320A). Each of these plugs is used with a specified voltage range. Most manufacturers use a yellow insulating material to distinguish these plugs from other similar-looking DC plugs.
- EIAJ-01: For 0–3.15 V. 2.5 mm OD, 0.7 mm ID.
- EIAJ-02: For 3.15–6.3 V. 4.0 mm OD, 1.7 mm ID.
- EIAJ-03: For 6.3–10.5 V. 5.0 mm OD, 1.7 mm ID.
- EIAJ-04 (also called JSBP 4): For 10.5–13.5 V. 5.5 mm OD, 3.4 mm ID.
- EIAJ-05 (also called JSBP 5): For 13.5–18 V. 6.5 mm OD, 4.4 mm ID.
EIAJ-04 and 05 have an internal male pin in the plug. The 01 through 03 sizes do not and are similar to the generic plugs in structure. These five EIAJ plugs are 9.5 mm in length and have a current rating of 2A.
There are two other, less common, connectors defined by EIAJ; RC-5321 and RC-5322. The latter is designed for both 12 V and 24 V automotive applications.
The German national standards organization DIN (Deutsches Institut für Normung—German Institute for Standardization) issued DIN 45323, which defines two DC power plug and jack (respectively) sizes. At least one of these sizes has a maximum rating of 34 V and 3 A. The information here is inferred from catalog references, as the German standard has not been translated into English yet.[when?]
- 5.00 mm OD, 2.00 mm ID, 14 mm long?
- 6.00 mm OD, 1.98 mm ID
Listing of DC coaxial connectors
This list attempts to show all known sizes, and is annotated with some manufacturers producing selected types, since each manufacturer makes its own unique subset of the known types. Note that the example part numbers given may have different connector barrel (sleeve) lengths, and are not necessarily exact equivalents. There are many more design variants than can be listed in this table, so only a small sampling of part numbers is given.
Connector size is often listed in the format OD (outer diameter) × ID (inner diameter) × L (length of barrel) and expressed in millimeters. Designations may vary between manufacturers.
Coaxial plugs that have a male center pin will have another measurement, Center Pin Diameter (CPD). These plugs are often used for higher power applications such as portable computers.
There are a number of sizes listed below that appear to be quite similar, and while the tolerances of these connectors are typically indicated as ±0.05 or ±0.03 mm by the manufacturers, there is still ambiguity as to whether two sizes differing by only 0.05 mm (or where the specification is only given to the nearest 0.10 mm) warrants listing them separately here.[original research?]
