A quick disconnect system for an accessory electrically coupled to a component of an amusement attraction includes a multi-part electrical enclosure including a first side, a second side opposite the first side, a first opening on the first side, and a relief pass through. The multi-part electrical enclosure is configured to: have a first electrical cable coupled to the accessory pass into the multi-part electrical enclosure via the first opening and have a second electrical cable pass into the second side of the multi-part electrical enclosure to enable the first and second cables to be coupled together within the multi-part electrical enclosure. The relief pass through is configured to provide strain relief to both the first electrical cable and the second electrical cable and to prevent disconnection of the accessory from the multi-part electrical enclosure.

A single multi-functional position holder is positioned in a receiving space of a housing to implement multiple functions of: satisfying a limitation on the height of a connector by making contact with an insertion portion and a concentric mounting portion of a connector assembly assembled through a curling process; increasing durability to absorb an internal load attributable to the curling process, by making tight contact with the housing; and preventing shaking of a PCB assembly due to a disturbance by restricting the PCB assembly to hold a PCB, thereby reducing the number of component parts of the connector, the process steps, and the cost. In particular, the multi-functional position holder is fixed in the housing without welding so that it is possible to remove a welding process from an assembling process of the connector.

An electrical assembly includes an electrical connector mounted upon a PCB and receiving a CPU therein, and a liquid Nitrogen heat dissipation device is mounted upon the PCB and intimately seated upon the CPU to remove the heat therefrom. The liquid Nitrogen heat dissipation device includes a case forming a chamber to receive the liquid Nitrogen therein. A plurality of fixing arms extend outwardly and radially to fix the liquid Nitrogent heat dissipation device in position. A fixing seat is attached upon the PCB to precisely located the CPU in position with regard to the electrical connector.

Provided are a receptacle connector configured to avoid damage to conductors of the receptacle connector. The receptacle connector includes a plurality of connection terminals, a mold structure which comprises a front part exposing each of the connection terminals and a support part disposed on a rear end of the front part and surrounding each of the connection terminals, and a shield which is disposed on the support part and comprises a conductive material, wherein the support part comprises a flat part which includes a surface along which the shield extends and a protruding part which protrudes from the surface of the flat part and is disposed in front of a front end of the shield. The protruding part is configured to avoid damage to conductors of the receptacle when a plug is mated to the receptacle.

A printed circuit board assembly having a printed circuit board with at least one footprint for attaching a plug connector, wherein the footprint has three or more coupling points for coupling electrical contacts of the plug connector, and a plug connector attached on the footprint, wthe plug connector has exactly two signal conductors for transmitting a differential signal, wherein the first signal conductor has a first electrical contact coupled at a first coupling point and the second signal conductor has a second electrical contact coupled at a second coupling point, wherein the second coupling point is not one of the coupling points which is directly adjacent to the first coupling point of the footprint.

An electrical connection device for connecting a plug, preferably a HV pin header, to a printed circuit board in a motor vehicle, having the following: at least one first electrical connection-device for contacting at least one assigned plug-connector contact; at least one second electrical connection-device contact for contacting at least one assigned printed-circuit-board contact wherein at least one first connection-device contact at least one second connection-device contact are connected to one another, wherein the electrical connection device is configured in such a manner that at least one printed-circuit-board contact is able to be selectively connected to assigned plug-connector contacts which differ in terms of the relative disposal thereof in relation to the printed-circuit-board contact and/or differ from one another in that said plug-connector contacts are a component part of plug connectors which differ from one another in terms of the configuration of the respective plug-connector contacts thereof.

A connection structure, of a short bar forming a conductive path and a land on a printed circuit board, in which the short bar includes a plate portion having a flat plate shape and a protrusion protruding in a stepped shape from a surface of the plate portion, the protrusion is threadably fastened to the printed circuit board by a screw inserted into a land-side through hole formed through the land, from an opposite side of the printed circuit board with respect to the protrusion, in a state where a flat surface portion formed, at a position spaced apart from the surface of the plate portion, on an outer surface of the protrusion is in close contact with the land.

A stacked I/O connector with surface mountable tails and a printed circuit board (PCB) configured to receive the connector. The connector may avoid terminal deformations or scratches when the connector is mounted to the PCB. The PCB may include solder pads on a single surface or both surfaces. The sold pads may be configured for the tails of the connector to be attached with a surface mount soldering technique. As a result, the connector has high density and high speed, requires, requires a smaller mounting area on a PCB, relaxes the limitations in routing PCB traces, and reduces the electrical performance deterioration caused by PCB trace routing limitations. The connector may have row-oriented terminal subassemblies, holes in the connector housing and other features to facilitate reliable manufacture and operation of the connector.

A crimp terminal (100, 101, 102, 103), a crimp terminal module (200), a terminal box and a tester. The crimp terminal is used for connecting to a wiring end of a sensing element. A press button (03) of the crimp terminal is pressed to drive a wiring port (010), formed by attaching a first attachment sheet (05) to a second attachment sheet (08), to open, so as to insert the wiring end of the sensing element into the wiring port. Compared with a traditional screwing means, the crimp terminal can reduce heat generated by friction and reduce the contact potential between a plug and the terminal, and facilitates improving working efficiency of batch detection.
