The first locking device and the second locking device are provided for use in a plug and a corresponding counter plug.

Systems and methods providing an electrical interface between a male plug (1002) and a female receptacle (100, 500, 1000, 1600). The methods comprise: receiving a conductive pin (402, 800, 1006, 1602) of the male plug in a socket opening (112, 900, 1012, 1612) of the female receptacle; providing (a) first spring loaded floating contact points (460) between an elongate body (422) of the conductive pin and an electrical contact (106A-106B) of the female receptacle and (b) at least one second spring loaded floating contact point (462) between a tip (420) of the conductive pin and the electrical contact (110) of the female receptacle, when the conductive pin is fully inserted into the female receptacle; and maintaining at least two of the spring loaded floating contact points when the pin moves within the socket opening as a result of an external force applied to the male plug or female receptacle.

An electrical connector is disclosed. The electrical connector includes a multi-diameter power pin having a proximal portion having a first diameter; an engagement portion having a second diameter smaller than the first diameter; a bearing portion having a third diameter smaller than the second diameter; and a threaded distal portion having a fourth diameter smaller than the third diameter. A receiving block having a multi-diameter through hole is configured to receive the multi-diameter power pin. The receiving block includes a plurality of gaps extending radially from the multi-diameter through hole to an outer surface of the receiving block, a receiving portion disposed between a lateral surface of the receiving block and a first gap of the plurality of gaps; and a clamping portion disposed between the plurality of gaps.

The current document is directed to methods and devices that facilitate object orientation. In particular, the current document is directed to methods and devices that facilitate tactile orientation of objects, such as connectors, keys, cards, and other objects that are manipulated by human users for insertion into complementary connectors, slots, and other receptacles. In addition to facilitating tactile orientation of objects, the devices and additionally provide mechanical advantage for objects insertion and removal and may additionally provide visual orientation indications, and other indications, to human users. The currently disclosed devices are tangible, physical objects or features that, when held, felt, and/or manipulated by human users, provide a tactile indication of the orientation of an engagement feature of an object is inserted into a complementary connector, slot, port, or other receptacle.

A rotatable coupling for audio cables is shown having a stator and a rotor divining an electrical rotary interface (301) for providing continuous connection between audio cables. A protective stator housing (304) retains the stator and a protective rotor housing (305) retains the rotor. A rolling-element bearing (306) with an inner race and an outer race allows the protective housings to axially rotate.

A connector receptacle for connecting with a corresponding connector plug coupled with electrodes being used for performing EMG procedure on a patient is provided. The receptacle includes a first ball bearing pressing against a first end of a housing of the plug and, preferably, a second ball bearing pressing against a first end of the housing of the plug when the plug is connected to the receptacle for exerting a retention force against the plug. The first and the second ball bearings are pressed against the first and the second ends respectively by using a spring force generated, for example, by a retention band.

An electrical connector comprises an insulating body, a pair of first terminal members, a pair of second terminal members, and a fastening part. The insulating body comprises a mating groove. The pair of first terminal members is disposed in the mating groove. Each of the first terminal members comprises a plurality of first elastic contacting parts. The pair of second terminal members is disposed in the mating groove. The pair of first terminal members is disposed between the pair of second terminal members. Each of the second terminal members comprises a plurality of second elastic contacting parts. The second elastic contacting part abuts against the first elastic contacting portion correspondingly. The fastening part fastens the pair of first terminal members and the pair of second terminal members.

A plug is connectable to an electrical socket which has concentric ring shaped openings housing electrical contacts. The plug has a body supporting electrically conductive concentric rings insertable into the socket to contact the electrical contacts to form electrical connections. A hollow post extends away from the plug body and has a transverse aperture therethrough. A rod with a narrowed portion is slideable within the post. A spring biases the rod towards a latched position in which the narrow portion is not adjacent to the transverse aperture. A cross-brace is connected to a portion of the rod which extends outside of the post. Pins engage the cross brace and can be pushed to move the brace, and thereby push the rod to position the narrowed portion to an unlatched position adjacent the aperture to enable removal of the plug.

An electrical connector assembly includes a male/plug/first connector and a female/receptacle/second connector mateable with each other. The first connector includes a first plate and a plurality of first contacts retained to the first plate, and the second connector includes a second plate and a plurality of second contacts retained to the second plate. The first plate includes opposite first long side and second long side to respectively form a first alignment structure and a second alignment structure which is offset from the first alignment structure in the longitudinal direction. The second plate includes opposite third long and fourth long side to respectively form a third alignment structure and a fourth alignment structure to be coupled to the corresponding first alignment structure and second alignment structure during mating.
