A connector includes a housing and a connector position assurance device (CPA). The CPA is movable between a first position and a second position and assures that the connector is completely mated with a mating connector or maintains a completely mated state in the second position. The housing has a mating portion, a guiding portion, and an abutting portion. The CPA has a base portion guided by the guiding portion and a beam portion. The abutting portion abuts on the beam portion in the first position during non-mating with the mating connector to block movement of the CPA to the second position. The mating connector during complete mating deforms the beam portion to remove the abutment of the beam portion on the abutting portion to allow the CPA to move to the second position.

A connector housing (20) includes a housing body (21) to which a mating connector housing is to be fit from front. A lock arm (40) has front and rear ends fixed to the housing body (21). A lock (42) is provided in a central part of the lock arm (40) in the front-rear direction and is configured to lock the mating connector housing. A pressing surface (43) is on a rear end part of the lock arm (40) and is configured to displace the lock (42) in an unlocking direction by being pressed. A coupling portion (44) couples the pressing surface (43) to the central part of the lock arm (40) in the front-rear direction.

A male internal conductor and a female internal conductor are reliably connected. When female-side and male-side dielectric bodies (16, 41) approach each other in an opposing positional relationship, a tab (32) of a male internal conductor (30) is inserted into a female-side dielectric body (41) and connected to a female internal conductor (42). The female-side dielectric body (41) has an opposing surface (41S) facing the male-side dielectric body (16) and formed with a female-side positioning portion (47). The male-side dielectric body (16) has an opposing surface (22S) facing the female-side dielectric body (41) and formed with a male-side positioning portion (25) which is disposed ahead of the tab (32) and which can be fitted with the female-side positioning portion (47) in a state where the tab (32) is not in contact with the female-side dielectric body (41).

The invention relates to a plug connection (1) which consists of a plug connector (2) and a mating plug connector (3) that can be plugged together in order to form the plug connection (1), comprising a retraction aid which is arranged on a part of the plug connector (1) and which interacts with another part on the mating plug connector (3). The plug connector (1) and the mating plug connector (3) have a retraction aid, said retraction aid being actuated axially in the plug-in direction automatically when the plug connector and the mating plug connector are plugged together.

An male modular connector (e.g., 8P8C) has a first set of electrical contacts on a first side and a second set of electrical contacts on an opposite, second side; and an elongated housing (in comparison to the IEC standards) so as to allow for the retaining clip of the male modular connector to be shifted farther back so as to not interfere with the connection between the pins and the electrical contacts of a female modular connector. A network switch has a non-cuboidal housing comprising two or more sidewalls, each sidewall comprising a plurality of female connectors (such as 8P8C, 16P16C, fiber optic, or other connector); and wherein some or all of the female connectors are parallel to the sides of the cabinet. The network switch is mounted from the front of the cabinet, with cables running horizontally to other cabinets and various mechanisms for protecting, organizing and managing the cables.

A closing device for releasably connecting two parts includes a first closing part which has a first engaging projection, and a second closing part which has a second engaging projections. The first closing part and the second closing part can be attached to each other in order to close the closing device and, in a closed position, are interconnected mechanically by the first engaging projection and the second engaging projection is in engagement with each other in a positive locking manner in the closed position. A magnetic device acting between the first closing part and the second closing part is designed to assist the attaching of the first closing part and the second closing part to each other by providing a magnetic attraction force. The first closing part has at least one first electrical contact element and the second closing part has at least one second electrical contact element.

A connector includes a first connector portion having projection units and at least one locking portion situated between at least one pair of adjacent projection units, and a second connector portion having fitting hole units and at least one portion to be locked, each projection unit of the first connector portion being fitted into each fitting hole unit of the second connector portion as catching a first contact portion of a first circuit board and a second contact portion of a second circuit board that face to be overlapped on each other, the first contact portion and the second contact portion being electrically connected to each other between a lateral surface of each projection unit and an inner surface of each fitting hole unit, while each locking portion is caught on a corresponding portion to be locked.
