An electrical connection device comprises an insulation body, an electrical connection component and a temperature sensing module. The electrical connection component is connected to the insulation body, and the electrical connection component includes a plurality of conductive terminals. The temperature sensing module is positioned between the insulation body and the electrical connection component, and the temperature sensing module is arranged in the insulation body. The temperature sensing module is configured to be adjacent to the conductive terminals.

An electrical connector includes a housing including a main body and an outer shield extending from the main body. One or more electrical contacts extend into an interface chamber within the outer shield. A membrane is coupled to the housing. An alert device is coupled to the housing. The membrane in a normal state connects to the alert device to short the alert device. The membrane in an alerted state disconnects from the alert device so that the alert device is not shorted, and wherein the alert device outputs an alert signal when the alert device is not shorted.

An example electronic device may include a connector; and a printed circuit board electrically connected to the connector, wherein the connector may include: a mid plate that includes a first surface and a second surface opposite to the first surface; a plurality of terminals; and an insulating structure in which at least a part of the mid plate is disposed and supporting at least some of the plurality of terminals, wherein the plurality of terminals may include a ground terminal that is disposed to be spaced apart at least in part in a first direction or in a second direction opposite to the first direction with respect to the mid plate, is extended in a length direction of the connector, and is in contact with the mid plate at one end thereof and is in contact with the printed circuit board at the other end thereof.

Systems, methods, and articles for a portable power case are disclosed. The portable power case is comprised of at least one battery and at least one PCB. The portable power case has at least two access ports, at least two leads, or at least one access port and at least one lead and at least one USB port. The portable power case is operable to supply power to an amplifier, a radio, a wearable battery, a mobile phone, and a tablet. The portable power case is operable to be charged using solar panels, vehicle batteries, AC adapters, non-rechargeable batteries, and generators. The portable power case provides for modularity that allows the user to disassemble and selectively remove the batteries installed within the portable power case housing.
