A housing assembly for an electrical connector includes a base element having an opening, a cover for covering the opening, and a locking mechanism. The locking mechanism has a slidable member movable into a locking position in which the locking mechanism locks the cover relative to the base element. The locking mechanism has a transmission element for transmitting force and movement onto the locking mechanism.

The application relates to a connector housing, a connector housing assembly and a connector assembly. The connector housing has a housing body and a shroud. The housing body encloses an accommodating cavity. The shroud is disposed around and connected to the housing body. A gap is formed between the shroud and the housing body to form a slot. The connector housing is further provided with one of a lug or a sliding groove. The lug or the sliding groove is positioned in the slot. According to the connector housing assembly and the connector assembly in the application, the lugs are matched with the sliding grooves to guide the first connector housing and the second connector housing during plug-in connection, so as to avoid failure of installation in place due to relative deflection of them.

A connector with booster mechanism includes a housing, an operation lever rotatably mounted on the housing and including an arm portion, a drive gear integrally rotatably provided on the operation lever, a speed-reduction member rotatably mounted on the housing, and a slider. The drive gear is coaxial with a rotation center shaft and disposed at a position different from the arm portion in an axial direction of the rotation center shaft. The speed-reduction member includes a large-diameter gear to be meshed with the drive gear and a small-diameter gear having a smaller diameter than the large-diameter gear and coaxial with the large-diameter gear. The slider includes a rack to be meshed with the small-diameter gear and is mounted on the housing movably in a direction intersecting a connecting direction to a mating connector.

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).

The present invention discloses a plug. A plug body 10 includes a pair of contact pins P for electrical contact and a lever-receiving groove 12. A single manipulation lever 20, is rotationally supported by a support shaft 22 within the lever-receiving groove 12, and includes a manipulation arm 24, and a gear arm 26 having a gear part 26a. A up and down movement member 40 includes a rack gear part 42, and a push pin 44 for entering or exit from the bottom of the plug body. When the up and down movement member moves down by a rotational movement of the manipulation lever 20, the push pin protrudes from the bottom of the plug body and presses a top of the socket, so the plug is separated from the socket.

A housing assembly for a connector includes a securing mechanism for securing the connector to a mating connector in a securing position, and a locking mechanism. The locking mechanism in a locking position locks the securing mechanism in the securing position. The locking mechanism is latchable in a holding position in which the securing mechanism can be moved out of the securing position.

The present disclosure provides an electric connector, which is used for being electrically connected with another adaptive connector (socket). The electric connector comprises a first shell, a lock plate, a second shell and an actuating assembly, wherein at least one electric connection point capable of being connected with the other connector is accommodated in the first shell; the lock plate is relatively fixed with the first shell; the second shell is at least partially located on the outer side of the lock plate and can move between a first position and a second position, the part of the second shell deforms the lock plate towards the inner side, so that the lock plate is tightly pressed with the outer surface of an outer shell of the other connector for frictional locking. According to the electric connector, the locking and pressing frictional force between the electric connectors can, be improved.

An automotive electrical distribution center assembly includes a mounting frame, a first pair of stacked gears rotatably attached to a side of the mounting frame and a second pair of stacked gears rotatably attached to an opposite side of the mounting frame, a moveable driver surrounding the mounting frame and defining four first linear gear racks that each engage a first gear of the first and second pairs of stacked gears, and an electrical distribution center attached to the driver. The electrical distribution center defines four second liner gear racks that each engage a second gear of the first and second pairs of stacked gears. Linear movement of the driver relative to the mounting frame causes rotational movement of the first and second pairs of stacked gears, thereby causing linear movement of the electrical distribution center to relative the mounting frame.

A plug connector for plugging onto or into a counterpart plug connector, having at least two counterpart contact elements, in a plugging direction. The plug connector has a housing having a first plane that faces in the plugging direction. The housing has at least two contact chambers, each of which has an opening in the first plane. At least two of the contact chambers in the housing are embodied separately from one another. A wall, which protrudes from the first plane when viewed oppositely from the plugging direction, is disposed between at least two mutually adjacent contact chambers. Alternatively or additionally, at least one groove is disposed in the first plane between at least two mutually adjacent contact chambers.

A locking pin driving mechanism includes a motor, a preceding gear, a round gear, a feed screw and a slider. The feed screw is coaxially fixed to the round gear. A locking pin is mounted in the slider. A center axis of the locking pin and a center axis of the feed screw are each disposed in parallel with a center axis of a vehicle inlet. An interaxial distance between the center axis of the vehicle inlet and the center axis of the feed screw is set to be larger than an interaxial distance between the center axis of the vehicle inlet and the center axis of the locking pin.
