Embodiments of a securing system for plug connectors may have an adapter and a pair of housing parts, each with at least one plug place with a plug place interface for receiving the adapter whose exterior may have an adapter interface for positioning in the plug space. The adapter may have an interior geometry for receiving a plug connector. The exterior of the adapter and the plug place may form a primary securing means for securing the adapter in the respective plug place when the adapter is inserted into a defined plug position to secure the adapter in the plug place. Embodiments may include a secondary securing means, which can be plugged into the housing part up to a defined end position at which the secondary securing device to secure the plug connector in the adapter.

A bulkhead passthrough connector containing a printed circuit board (PCB) for transferring electrical signals across a bulkhead to an electronic valve actuator, an electronic valve actuator configured to operate and communicate with a valve using a PCB through a bulkhead, the electronic valve actuator, and a method of assembling a bulkhead passthrough connector incorporating a PCB. The embodiments may include a passthrough partition which separates one side of the bulkhead from another. A PCB retainer may also be secured to the passthrough partition. The PCB is attached to the PCB retainer and extends from one side to another side of the bulkhead through the passthrough partition. The PCB further includes electrical paths printed on the PCB and electrical connectors located on both sides of the bulkhead to enable communication with external devices.

A terminal position assurance device and a corresponding connector assembly are disclosed. The terminal position assurance device includes a main body having a main board, an upper board, and a lower board. The upper board and the lower board are arranged perpendicularly to the main board and are located on the same side of the main board. The upper board and the lower board have distal ends away from the main board. The terminal position assurance device further includes an extension arm extending from the distal end of the upper board in a direction substantially perpendicular to the main board and a stopper extending from an outer edge of the extension arm and thus going beyond the main body.

A shell assembly includes a shell including a depression and a flange, which go around a circumference of the shell, and the shell assemblies are arranged in N rows×M columns and fixed to a housing. The housing includes: N×M pieces of insertion holes into which respective ends of the shell assemblies are inserted; an engagement portion that is formed on an inner surface of each of the insertion holes on a position, which is closer to an obliquely-adjacent insertion hole of the insertion holes, and is engaged with the depression; and a slit that is formed by cutting the housing in a direction orthogonal to an extension direction of the insertion holes and includes a first groove and a second groove formed on an inner surface thereof.

A connector assembly includes a connector body defining a plurality of cavities, extending longitudinally through the connector body. The cavities are configured to receive inner terminal housings configured to hold electrical terminals attached to electrical cables disposed within the cavities. The connector assembly further includes a retaining device slidably attached to the connector body and moveable from a pre-staged position to a staged position. The retaining device allows the inner terminal housings to be inserted or removed from the cavities when in the pre-staged position and inhibits the inner terminal housings from being inserted or removed from the cavities when in the staged position.

A connector body has a body terminal passageway configured to accommodate a terminal and a block accommodating part configured to communicate with the body terminal passageway. An assembly block is detachably connected to the connector body, rotatable about the connector body while maintaining a state in which the assembly block is connected to the connector body while an external force is applied, and configured to rotate at a predetermined angle or more to be separated from the connector body and be insertable into the block accommodating part.

A connector for a flat flexible cable includes a housing and a terminal disposed in the housing. The housing has a base and a cover. The base has a closed section with a receiving passageway and an open section extending from the closed section. The cover encloses the open section in a closed position of the cover. The cover has a main body with a pressing surface and a latch extending from the main body. The latch engages a catch of the base in the closed position. The terminal is disposed in the receiving passageway and has a tab extending into the open section. The pressing surface abuts the tab and presses the tab toward the base in the closed position.

An electrical connector for connecting with a mating electrical connector in a mating direction includes an electrically conductive terminal having an electrical contact, a housing having a plug-in portion insertable into the mating electrical connector along the mating direction, the plug-in portion having a receptacle receiving the electrical contact, a compressive member arranged within the housing and compressed along the mating direction, and a connector position assurance element (CPA) slidable from an unlocked position to a locked position along the mating direction. The locked position allows the electrical connector to be locked to the mating connector when the electrical connector is connected to the mating connector. A central axis of the compressive member is aligned with a central axis of the plug-in portion in the mating direction.

Example implementations relate to an electronic port of an electronic device, having a locking assembly to secure an electronic plug within the electronic device. The electronic port includes a receptacle, and the locking assembly including a rocker switch, a bracket, and an elastic arm. The receptacle is releasably connectable to a connector of the electronic plug. The rocker switch is pivotably connected to an enclosure of the electronic device. The bracket extends from the rocker switch, and disposed around a first end portion of the receptacle. The elastic arm includes a locking tab engaged with the bracket, and a seating tab seated on a second end portion of the receptacle. Where, in relaxed state of the elastic arm, lock features of the locking tab protrudes into the receptacle, and where the elastic arm is deformable from relaxed state to biased state to pull the lock features out of the receptacle.

Shown is an assembly or securing a printed circuit board to a plug body, having a contact element with a holding face facing against a plugging direction of the contact element, and a securing member, that can be transferred into a securing position, in which the printed circuit board is secured by the securing member in a positive fit manner against the plug direction at the holding face. Further shown is a method of securing a printed circuit board at the plug body, wherein a holding face of a contact element facing against a plug direction is inserted through an opening in the printed circuit board and subsequently a securing member is transferred to a securing position, in which the printed circuit board is secured by the securing member in a positive fit manner against the plug direction at the holding face.
