An electrical connector with extension terminals includes an insulating housing, a movable terminal, a spring and a conductive reed terminal. The insulating housing has terminal axial holes each having a ridge. The insulating housing has reed sockets arranged around and communicated with the terminal axial holes. The movable terminal accommodates therein a spring. The movable terminal has a groove. The movable terminal is such inserted into the terminal axial hole of the insulating housing that the groove fittingly receives the ridge, thereby limiting the movable terminal to move in the terminal axial hole but preventing the movable terminal from leaving from and rotating in the terminal axial hole. The conductive reed terminal has inserts and a weld leg. The insert has a reed. When the insert is inserted into the reed socket, the reed abuts against the movable terminal, thereby establishing conductivity therebetween.

The present disclosure relates to a card socket for an electronic device and, more particularly, to a card socket for an electronic device having an improved card insertion confirmation structure, wherein the structure of a card insertion confirmation terminal, which senses full insertion of a card or a tray into a card socket, is changed so as to improve stability of insertion of the card or the tray.

An arc prevention system including a jack having a receptacle, a modular plug sized to be positioned in the receptacle of the jack, the modular connector including, a plurality of contacts, with at least two of the contacts creating an energized electrical path with an external power source in electrical communication with the external power source, a latch extending from a top surface of the modular plug, a switching unit positioned on the latch, a control circuit in electrical communication with the switch and the at least two energized contacts, where the electrical path between the control circuit and the switching unit is not energized, and the control circuit adjusts the energized electrical path to a predetermined electrical level.

The present invention discloses a sofa USB socket including: a USB female socket including a tongue core, wherein the tongue core includes 5 pins, and the fifth pin is an ID pin; and a USB circuit including a power circuit, a filter circuit, a control chip and a buck chopper circuit, wherein the buck chopper circuit includes a transistor, and the ID pin is electrically connected with the transistor. When an external USB male plug is inserted into the USB female socket, the power circuit supplies power to the USB female socket; when the USB female socket is in an unloaded state, the fifth pin is suspended, the control chip enters a sleep state, and the USB female socket has no output voltage, which greatly reduces the no-load energy consumption, thereby being beneficial to extending the endurance time and the service life of a power supply battery.

Disclosed herein is a safety outlet. The safety outlet includes a casing having at least one hole into which a pin of a plug is inserted; and at least one drain pipe forming a drain channel for independently communicating the at least one hole and the outside of the casing; wherein the drain channel provided in the at least one drain pipe each serves as drain passage separated from each other, and the drain pipe is partitioned so as to maintain sealing between inside of the casing and the drain channel, wherein a contact portion connected to a power terminal arranged outside of the at least one drain pipe is provided in the at least one drain pipe.

A connection switching device is provided which connects a plug, having a plug pin connected to an inspecting circuit, to a receptacle connector connecting an antenna and a transmission/reception circuit, and switches a connection to a parallel connection where the inspection circuit is connected to the antenna and to the transmission/reception circuit. The receptacle connector includes a first contact, a second contact, and a normally closed terminal that is brought into elastic contact with the first contact and the second contact. The plug includes a first plug pin being brought into contact with the first contact, a second plug pin being brought into contact with the second contact, and an insulating projection being inserted between at least one of the first and second contacts and the normally closed terminal to insulate between the at least one of the first and second contacts and the normally closed terminal.

The invention relates to a contact element arrangement consisting of a shaped sheet metal part, wherein at least two contact elements, which are spaced apart from each other and extend away from a flat base plate of the sheet metal part, are shaped from the sheet metal part and wherein the one contact element forms a substantially cylindrical contacting portion for mounting a pin-shaped counter contact by insertion and wherein the second contact element is formed as a contact spring bent in an S-shape over two bending portions, the contact spring forming a contact point facing away from the base plate.

A plug electrical connector including an insulator, a plurality of elastic terminals, at least one shielding spring, and an outer shell is provided. The elastic terminals are disposed in the insulator and arranged along an axial direction. The elastic terminals includes at least one grounding terminal arranged at a first position or a last position of the elastic terminals. The shielding spring is assembled to an exterior surface of the insulator. A portion of the shielding spring on the axial direction is disposed on a deformable path of the grounding terminal. The insulator, the elastic terminals, and the shielding spring are accommodated in the outer shell.

A feed-through terminal block module includes first and second electrical terminals, a first current bar, and a second current bar, the terminals and current bars in a terminal housing. The first current bar permanently electrically connects the first and second terminals. The first current bar includes a first contact portion of the module. The second current bar includes a second contact portion of the module and a third contact portion of the module. A removable contact plug is inserted into the housing to selectively electrically connect the first and second contact portions. Removable bridge pins or a bridging current bar electrically connects the third contact portions of adjacent modules when modules are placed side-by-side to form a terminal block.

In one example, a connector for providing security to an article of merchandise is provided, wherein the article of merchandise includes an input port and internal circuitry. The connector includes a connection portion configured to releasably engage the input port of the article of merchandise. The connector also includes a conductive shield and at least one pair of ground conductors. At least one of the ground conductors is configured to electrically connect to the conductive shield to define a sense loop when the connector is engaged with the article of merchandise. Interruption of the sense loop is indicative of a security event.
