An electrical connector includes a housing, a primary locking sleeve disposed on the housing, and a securing tab. The housing has a receptacle open in a connection direction essentially parallel to a longitudinal axis, the receptacle receiving a complementary connector. The primary locking sleeve is movable relative to the housing between a locked position securing the electrical connector and the complementary connector and a release position for connecting and/or disconnecting the electrical connector and the complementary connector. A gap having a gap width is disposed between the housing and the primary locking sleeve at least in the locked position. The gap width decreases from the locked position to the release position. The securing tab is insertable at least partially into the gap to an inserted state to secure the primary locking sleeve in the locked position.

An electric vehicle fastening and charging combined system for a charging and storage station, such as those used for bicycle or scooter sharing programs, where a multi-purpose cable extends between the charging and storage station and the electric vehicle, and serves to fasten the electric vehicle to the charging and storage station to prevent removal or theft of the electric vehicle, and to conduct electricity to charge the electric vehicle, and wherein the fastening and/or detaching of the cable is controlled by a wireless signal.

An electrical connector includes a first member, a second member, and a sleeve connected to the first member. The sleeve may connect with a first component. The second member may connect with a second component. The first member may include a flange. The first portion of the sleeve may be disposed substantially at a first axial side of the flange. A second portion of the sleeve may be disposed substantially at a second axial side. The first and second members may include corresponding latching portions configured to selectively connect the first member with the second member and restrict relative axial movement between the first member and the second member. The latching portion of the second member may include a latching spring, and the latching portion of the first member may include a latching spring groove. When latched, the latching spring may be at least partially in the latching spring groove.

An electrical connector includes an insulation body, a seat, and a positioning plug. The seat is disposed on an outer peripheral surface of the insulation body. The seat includes a tunnel defined through the seat to form an inlet and an outlet. The outlet and a front surface of the insulation body face the same side. The seat further includes a slit and one or more first bumps disposed on an inner wall of the slit. The positioning plug includes a sliding block and rib. The sliding block movably disposed in the tunnel via the inlet with the rib movably disposed in the slit. The positioning plug further includes a second bump disposed on a lateral side of the rib facing the first bump. When the sliding block moves to an installation position, the first bump stops the second bump to fix the sliding block at the installation position.

A connector includes an outer housing, an inner housing fitted to the outer housing, and a detection member assembled to the outer housing and restricted from being separated in a removal direction. The detection member has a flexible lock arm and a member-side protrusion formed on a free end side of the lock arm and facing an outer-side protrusion in the removal direction in an assembled state. When a locking arm gets over the outer-side protrusion and is locked to the outer-side protrusion, the locking arm moves in an insertion direction while being elastically deformed, and elastically returns after getting over the outer-side protrusion to press the member-side protrusion outward an inner housing accommodating space, so that the lock arm allows the outer-side protrusion and the member-side protrusion to be in a non-facing state in the insertion/removal direction, and allows the detection member to be separated in the removal direction.

An electrical connector system with a receptacle and plug. The receptacle has a metal housing encircling an insulative housing. A side wall of the metal housing is separated from a corresponding side wall of the insulative housing, leaving a groove. The plug has a wall, extending from an insulative housing of the plug, parallel to a paddle card. The metal housing may be shaped to engage with the wall during mating of the plug and receptacle, facilitating alignment of the paddle card and plug interface of the receptacle. The wall may also carry latching components, which may latch to corresponding features of the metal housing, reducing the height of the mated connectors in comparison to configurations in which the latching components are mounted to the insulative housing of the plug. The receptacle housing may have asymmetric support parts, providing support in a compact space.

A test plug block (1) for plugging onto a series terminal block (2), comprising a plurality of test plugs (4) connected to one another and two fastening parts (5), which are arranged on both sides of the plurality of test plugs (4) and are connected to one another by means of a grip piece (6), the fastening parts (5) each having a housing (7) and an insertion portion (8), which can be inserted into a receiving portion (9), the receiving portion (9) being formed in the clamp housing (10) of a fastening clamp (11) of the series terminal block (2).

An electronic device and an input/output connector are disclosed. The device may include the input/output connector, which may include a housing including an opening, a cover that covers at least a portion of the opening, the cover connected to the housing by a hinge, and forming an external appearance of the electronic device together with the housing, an elastic body connected to the housing and the cover, and an insertion hole formed by the housing and the cover, into which a cable terminal is insertable for connection with an external device, wherein a size of the insertion hole is changeable according to the rotation of the cover.
