A connector includes a housing, a terminal arranged in the housing, and an elastic cantilever on an outside of a top wall of the housing and extending along a length direction of the housing. The elastic cantilever has a pair of sides opposite to each other in a width direction of the housing. A snap protruding along the width direction is formed on one of the sides of the elastic cantilever. The snap engages a mating snap formed on a mating housing of a mating connector to lock the connector and the mating connector together.

In a charging connector, contacts are divided into a first terminal group and a second terminal group. The first terminal group is located upward of the second terminal group. A housing has a first surrounding portion which protrudes from a main surface thereof and surrounds the first terminal group. A mating portion has an attaching portion, a second surrounding portion and an upper protection portion. The attaching portion is attached on the main surface of the housing. The attaching portion is provided with an opening which penetrates therethrough in the front-rear direction. The first surrounding portion of the housing extends forward through the opening. The second surrounding portion is located downward of the opening. The second surrounding portion protrudes forward from the attaching portion and surrounds the second terminal group. The upper protection portion is located upward of the opening and protrudes forward from the attaching portion.

A plug includes a body portion as well as first and second electrical strip contacts. The body portion has a length, an upper surface and a lower surface. The first electrical strip contact is proximate the upper surface of the body portion and has a length substantially equal to or less than the length of the body portion. The second electrical strip contact is proximate the lower surface of the body portion and has a length substantially equal to or less than the length of the body portion.

The installation comprises a connector with a body and input openings connected to a housing used for receiving the male terminals. The installation also comprises output openings through which the female terminal wiring is passed, separation walls, side tabs and a first cover hinged to the connector and characterised in that it incorporates a second hinged cover on the aforementioned connector that is facing the first cover, which blocks the side tabs when closed and defines a base, and female terminals made of an electrical conductive material and housed in the connector housing. The female terminals expand when the male terminals are inserted inside them and the area of the housing is greater than the area occupied by the female terminals prior to expanding.

An example electrical connector includes a body to receive a circuit board. The body includes a first end and a second end. The electrical connector also includes a first latch rotatably attaches to the first end. The electrical connector further includes a second latch rotatably attaches to the second end. The electrical connector further includes a link member attached to the body. In response to a rotation of the first latch, the link member is to slide across the body from the first latch towards the second latch to rotate the second latch.

A plug-in connector part connectable to a mating connector part so as to form a plug-in connection includes: a housing; and an elastically deformable locking component embodied separately from the housing, which reversibly locks to a locking contour of the mating connector part during a creation of the plug-in connection. The locking component is at least partially arranged in the housing of the plug-in connector part and has a section that is curved around a longitudinal axis of the plug-in connector part, which is parallel to the plug-in direction, and has at least one locking region and at least one unlocking region. The locking component is prestressed in a closed position and is elastically radially outwardly expandable into an open position in the locking region by an action of a radially inwardly oriented force on the unlocking region.

Example implementations relate to point of sale cables. For example, a system may comprise a point of sale terminal coupled to a splitter via a registered jack (RJ) cable to provide electrical power to the splitter, a receipt printer coupled to receive electrical power from the splitter at a DIN connector input; and a cash drawer to receive electrical power from the splitter via an RJ connector input.

The invention provides an electrical connector with a structure that maintains connection stability and enables easy removal so as not to cause any damage during removal while the size is reduced (particularly, in a widthwise pitch direction) and the profile is reduced. At the time of removal of two connectors 20 and 40, when an operation portion 601 of a locking member 60 of the receptacle connector 40 is pushed inward in the longitudinal pitch direction, a locking piece 602 of the locking member 60 pushes and spreads an engagement portion 502 of an engagement member 50 outward in the widthwise direction, and simultaneously a protrusion portion 501 is also moved outward in the widthwise direction, whereby the aforementioned lapped state is released and unlocked, enabling removal. When the operation portion 601 is released, the locking piece 602 is pushed inward in the widthwise direction by resiliency of the engagement portion 502, and the protrusion portion 501 is returned to the initial position corresponding to the position in which the protrusion portion 501 is lapped with a step portion 303 when viewed from the fitting direction at the time of completion of fitting.

A multi-functional charger includes an upper housing, a lower housing, a receiving cavity, a PCB, a two-phase mother plug, and a child plug. The receiving cavity is defined between the upper housing and the lower housing. An opening is defined in a side of the upper housing and the lower housing. The PCB is located in the receiving cavity. The multi-functional charger can use conducting member to couple to the PCB, the circuit may be more stability and more safety. It is easy to be assembled, and a various type of child plugs can be coupled to the mother plug. It is also easy to use with good user experience.
