The connecting parts respectively connect a lower end portion of the pressing part and a lower end portion of each of the side wall parts disposed on the both sides in the array direction. Holding parts are respectively formed on the both sides in the array direction of the pressing part, the holding parts holding the connectors together with the pressing part, the side wall parts, and the connecting parts.

A plug connector part for connecting to a mating plug connector part includes: a housing part; an inlet part that is connectable to the housing part, the inlet part having a plug section on which at least one contact element is arrangeable for a plug-in connection to the mating plug connector part; and a locking frame having at least one first latching element, the locking frame being latched in a first mounting position to the inlet part via the at least one first latching element in order to attach the inlet part together with the locking frame to the housing part. The inlet part in a position attached to the housing part is connected in a positive-locking manner to the housing part via at least one second latching element. The locking frame is movable from the first mounting position relative to the inlet part to a second mounting position.

A street light has a pole of at least 6 feet in length, and has an electrical socket attached to an end of the pole. The socket includes a body having an interior, and a cover positioned on the body to cover the interior of the body. The cover has a ring-shaped openings providing passage into the interior of the body. Resiliently mounted electrical contactors are each positioned in the interior of the body and adjacent to one of the ring-shaped openings in the cover. A central bore extends through the body, and a ledge is positioned at the end of the bore to extend radially outward. The socket is connectable to a mating plug to mechanically and electrically connect a street light or other device to the pole. The street light can include sensors that are connectable using a similar socket and plug.

A high speed wire end connector includes a printed circuit board, a cable, an inner film, an outer casing, and a molded bonding layer. The cable is soldered to the printed circuit board, the inner film covers a part of the cable and a part of the printed circuit board, and the outer casing is used to fix the printed circuit board, the cable and the printed circuit board, and a part of the printed circuit board is passed through a guide hole of the outer casing. The molded bonding layer bonds the outer casing to the inner film. In addition, a metal spring latch is mounted on the outer casing.

A connector assembly includes a wire end connector for electrically connecting to a board end connector. The wire end connector includes a main body portion and an insertion portion. The insertion portion is connected to the main body portion, and the insertion portion is configured to couple to the board end connector. The main body portion is provided with a plurality of elastic claws extending outward from the main body portion to press on the board end connector when the insertion portion is coupled to the board end connector so as to stably connect the wire end connector to the board end connector.

A connector housing includes a housing main body formed from a first material and a latch arm formed from a second material having a lower rigidity than the first material. The latch arm extends in a cantilever form, forms a boundary portion at a connection between the latch arm and the housing main body, and is configured to elastically deform in relation to the housing main body to latch a latched member. A transition region having a continuously variable mixing ratio between the first material and the second material is present within an expanded boundary region including the boundary portion and expanding into the housing main body and into the latch arm.

A connector (10) includes a housing (20) and a connection detecting member (60) that is displaceable between a connection assurance position and a connection assurance release position. The connection detecting member (60) is mountable on the housing (20) and pushed from a pre-assembling position to the connection assurance release position. First arms (74) are on sides of the connection detecting member (60). Two first guide grooves (44) and two second guide grooves (48) are in the side walls (42) of the housing (20) and extend along a sliding direction of the connection detecting member. First claws (76) of the first arms (74) are in the first guide grooves (44) at the connection assurance position and the connection assurance release position, and are in the second guide grooves (48) at the pre-assembling position. The first arms (74) deflect by pushing the connection detecting member (60) to the connection assurance release position.

A plug-in connector system includes: a first plug-in connector part and a second plug-in connector part, which are connectable to one another in a plug-in manner along a plug-in direction; and an encoding device having a first encoding part connectable to the first plug-in connector part and a second encoding part connectable to the second plug-in connector part. The first encoding part and the second encoding part are arrangeable together on the second plug-in connector in a pre-assembly position and the first encoding part is connectable with the first plug-in connector part during connecting of the first plug-in connector part and the second plug-in connector part and to remain on the first plug-in connector part during detaching of the first plug-in connector part and the second plug-in connector part from each other. One of the second plug-in connector part and the second encoding part has a locking section.

A connector includes a second housing fittable with a first housing, a slide member movable relative to the first housing along a connector fitting direction, a transmission gear member rotatably supported by a support shaft provided on the first housing, a first rack gear portion provided on the slide member along the connector fitting direction, a driven gear portion of the transmission gear member rotated by movement of the first rack gear portion in the connector fitting direction, a main drive gear portion of the transmission gear member provided on a side opposite to the driven gear portion with the support shaft interposed therebetween, and a second rack gear portion provided on the second housing along the connector fitting direction, and movable relative to the first housing along the connector fitting direction by rotation of the main drive gear portion.
