An electrical header for use in an electrical connector assembly includes a body adapted to mount to an object and having an opening formed therethrough for receiving an electrical terminal. The body further defines a plug on a first side thereof and adapted to engage with a mating electrical connector of the assembly. The plug includes a pair of first opposing sidewalls extending from the body and defining a locking feature adapted to engage with a corresponding locking feature of the mating connector, and a pair of second opposing sidewalls extending from the body and defining a keying feature. The first and second pairs of opposing sidewalls are adapted to mate with a first mating connector oriented in a first direction, and mate with a second mating connector oriented in a second direction distinct from the first direction.

A vacuum cleaner of the present invention comprises: a main body having a suction motor for generating suction force; a main PCB capable of generating a control command for the suction motor; a handle part capable of accommodating the main body PCB; and a connector provided at the main body, and to which the main PCB is connected in a process of coupling the handle part to the main body. The main PCB includes a plurality of pads and a slit, and the connector includes: a plurality of connecting pins for making contact with the plurality of pads; and a slit insertion protrusion inserted into the slit.

A card connector, a card holder, and a terminal device, where the card connector includes a plurality of first terminals and one or more second terminals. The first terminals are arranged to form a first card access area that installs a first card, and the first terminals are configured to be electrically coupled to the first card. The one or more second terminals are distributed on a periphery of the first card access area, the first terminals and the one or more second terminals form a second card access area that installs a second card, and the first terminals and the one or more second terminals are configured to be electrically coupled to the second card.

A vacuum cleaner of the present invention comprises: a main body having a suction motor for generating suction force; a main PCB capable of generating a control command for the suction motor; a handle part capable of accommodating the main body PCB; and a connector provided at the main body, and to which the main PCB is connected in a process of coupling the handle part to the main body. The main PCB includes a plurality of pads and a slit, and he connector includes: a plurality of connecting pins for making contact with the plurality of pads; and a slit insertion protrusion inserted into the slit.

A probe cover which is to be attached to a socket that is configured to support a plurality of contact probes, includes: a base; two positioning pins which are disposed on the base; and at least one supporting member which is disposed on the base. The two positioning pins and the supporting member are capable of positioning the base in a state where the base is separated from the socket by a predetermined distance, and a mutual separation distance between the two positioning pins is changeable.

An electric connector includes a plug and a socket. The plug includes a jack, a first lock and a second lock, the jack is defined inside the plug, and the first lock and the second lock are formed into the jack. The socket includes an insert part with a first hook and a second hook disposed thereon, and the insert part is configured to be inserted into the jack in an inserting direction. The first lock is located behind the second lock in the inserting direction. When the insert part is partly inserted into the jack the first hook engages with the first lock, and when the insert part is completely inserted into the jack the second hook engages with the second lock and the first hook is disengaged from the first lock, which makes the plug and the socket double lock preventing them separating from each other.

A multiple connector assembly includes a connector housing. A first connector and a second connector, adjacent the first connector, extend from a first surface of the connector housing. A securing member is coupled to the connector housing and is configured to engage a connector coupling member to secure the first connector in a first connector receptacle and the second connector in a second connector receptacle. A connector release actuator that is located on a second surface of the connector housing that is opposite the first surface of the connector housing. The connector release actuator is configured to actuate the securing member to cause the securing member to disengage with the connector coupling member such that the first connector is no longer secured in the first connector receptacle and the second connector is no longer secured in the second connector receptacle.

A rotatable receptacle and method of assembling and mounting a rotatable receptacle. The receptacle includes an outer ring that has a mounting surface for mounting to a housing, and a rotatable insert that is received in the outer ring. An inner surface of the outer ring surrounds an outer surface of the rotatable insert. The rotatable insert has an electrical face configured to mate with a photoelectric device and an opposite mounting face for mounting to the housing. The rotatable insert is rotatable with respect to the outer ring to orient the rotatable insert in a desired direction for optimal positioning of the photoelectric device. The outer ring and the rotatable insert have corresponding interlocking features configured to fix the rotatable insert in the desired direction.

It is aimed to enable a plurality of housings to be stacked without enlarging a connector. A connector includes a housing (60) including a lock receiving portion (67) inside and a case (10) internally provided with accommodation areas (13) capable of accommodating a plurality of the housings (60) in parallel and including lock portions (21) on back surfaces (18) of the accommodation areas (13), and the lock portions (21) resiliently lock the lock receiving portions (67) of the respective housings (60) to restrict the separation of the housings (60) from the accommodation areas (13).
