A plug connector includes a housing and multiple plug terminals. The housing has at least a base portion housing the multiple plug terminals, and a lock mechanism, and a pair of side portions each provided on both right and left sides of the base portion. At each of the side portions in a pair, a step portion is formed. In a state in which the plug connector is fitted in the receptacle connector, side surfaces of the step portions face the receptacle connector through a clearance, and front surfaces of the side portions are closer to the receptacle connector than the side surfaces of the step portions are to the receptacle connector.

The present disclosure provides a combined type hand warmer, including a first hand warmer unit and a second hand warmer unit; a first connection part is arranged on the first hand warmer unit, and a second connection part is arranged on the second hand warmer unit; the first connection part is detachably connected to the second connection part such that the first hand warmer unit and the second hand warmer unit are combined into a whole; and when a user needs to warm two hands/multiple body parts, the first hand warmer unit can be separated from the second hand warmer unit, and the first hand warmer unit and the second hand warmer unit can be respectively used for warming the two hands/multiple body parts.

The present invention relates to a latching system, including a printed circuit board and an edge-contact plug, for establishing a latching connection between the printed circuit board and the edge-contact plug, including two retaining arms, each having a latch, the edge-contact plug including two mating latches for establishing the latching connection with the latch. The mating latches being formed on two different outer sides of the edge-contact plug as a set-back portion on the outer sides in each case, and the latches being able to engage with the set-back portions on the outer sides to establish the latching connection.

An electrical connector, in particular for signal and/or power transmission, preferably for charging electric vehicles or of accumulators of electrical vehicles, has a coupling housing for connection to a corresponding second electrical connector. A locking clip on the coupling housing can be moved from an open position to a closed position. The locking clip has a recess into which a locking element of the second connector can be inserted in the open position of the locking clip, and in the closed position of the locking clip, the locking element is arranged in the recess such that the coupling housing is form-fit and/or force-fit connected to the second connector. A latching apparatus with at least one latching element engages in a latching receptacle of the locking clip in the closed position. An electrically movable locking element is arranged which inhibits movement of the latching element in a locking position.

A terminal block structure and an unbuckling unit thereof are disclosed. The unbuckling unit has a base member and a rotary member, the rotary member is connected to the base member to be operated. The rotary member includes a first arm part, a second arm part extended from the first arm part and a rotary part disposed between the first arm part and the second arm part. The second arm part has a buckling unit, and the rotary part is connected to the base member. When the first arm part is applied with an external force, the rotary member rotates about the rotary part as a rotation center to drive the second arm part to ascend. Accordingly, advantages of easily to be pressed and operated, simple in structure and convenient to be assembled are provided.

An integrated connector-antenna assembly is provided, wherein an antenna is monolithically integrated with a radio frequency (RF) connector housing. The connector-antenna assembly may also include the RF signal element, wherein the connector center pin is monolithically integrated to the connector housing. Although part of the connector-antenna assembly, the connector housing and connector signal element still serve the connector function, which is essentially a channel for RF signal from the RF signal source to the antenna.

Various disclosed embodiments include illustrative vehicle charging connectors, vehicle charging connector systems, and vehicle charging systems. In an illustrative embodiment a vehicle charging connector includes at least two electrical contacts configured to electrically connect with electrical contacts of a vehicle charge port. At least one controllable electromagnet may be configured to attract the vehicle charging connector to contact a charge port of an electric vehicle. The connector also includes at least one controllable electrically actuated mechanical connector configured to provide mechanical engagement and disengagement between the vehicle charging connector and the charge port.

A security sleeve system for a cable connector, includes: a first portion that may engage a tightening portion of a cable connector; and a second portion that may engage the first portion. The first portion may be configured to engage the tightening portion such that rotation of the first portion in a tightening direction causes the tightening portion to rotate; the first portion and the second portion may be configured to receive a tool that impedes rotation of the second portion relative to the first portion to cause the tightening portion to rotate in a loosening direction; the second portion may be configured to rotate relative to the first portion when the tool is not received in the first portion; and the first portion and the second portion may be configured to provide tool-less tightening of the cable connector to a mating part but are configured to use a tool to loosen the cable connector from the mating part.
