A charging system for a battery-operated machine is disclosed. The charging system includes a charging receptacle having a power connection and a signal connection, with the charging receptacle configured to receive electrical current via the power connection from a power supply plug. The charging system further includes a heat rejection element thermally coupled to the charging receptacle, a temperature sensor, and a charging controller operatively coupled to the temperature sensor and the charging receptacle. The charging controller is configured to receive a temperature signal from the temperature sensor, the temperature signal being indicative of a charging-receptacle temperature. The charging controller is further configured to transmit, via the signal connection to the connected plug, a control signal to adjust (e.g., raise or lower) the electrical current supplied to the power connection.

An interconnect is disclosed that opens a battery circuit when an access cover is removed. The interconnect includes a single installed position, and does not include any throw positions to avoid ambiguity. The interconnect includes a conductive element that closes the battery circuit when the interconnect is installed. The access cover cannot be removed when the interconnect is installed, because the interconnect includes at least one mechanical feature that prevents removal of the access cover. In some instances, the interconnect is integrated into the access cover, such that when the cover is removed, the circuit is opened necessarily during removal. The interconnect interface may include blades, pins, or other electrically conducting elements. The interconnect is arranged in the battery system away from power electronics and other components that may interface to an electrical load, thus providing an added measure of safety when the access cover is off.

There is provided a connector including: a sacrificial pressing surface that is provided in a second housing and is a flat surface formed at an end portion on a side opposite in an insertion direction of the second housing. When an external force acts on the second housing in a temporarily assembled state in which the second housing is more shallowly fitted to a first housing than in a fully assembled state and a locking portion is not locked to a locked portion, the sacrificial pressing surface is configured to cause a pressing force to act in a direction in which a contact area of the locked portion with respect to the locking portion is larger than that in a case in which the second housing is pressed in the insertion direction.

There is provided a connector including: a protrusion portion provided on a second housing at a position close to and facing a distal end portion of a locking portion in a locked state in which the locking portion is locked to a locked portion, so that the protrusion portion restricts an action of an external force on the distal end portion of the locking portion in the locked state.

In order to achieve impedance matching, a connector (A) is provided with: a housing (10) having terminal receiving chambers (11) disposed in two rows; two short-circuit members (30) which are attached to a plurality of terminal receiving chambers (11) arrayed in one row and a plurality of terminal receiving chambers (11) arrayed in the other row, and which constitute a differential pair; a plurality of terminal fixtures (40) which are separately fixedly attached to a main line (51) constituting the differential pair and a sub-line (52) constituting the differential pair, and which are inserted into the terminal receiving chambers (11) and are thereby connected to the short-circuit members (30); and a plurality of lances (13) formed on the housing (10) to prevent removal of the terminal fixtures (40) inserted into the terminal receiving chambers (11). The lances (13) are only provided in regions different from a region sandwiched between the plurality of terminal receiving chambers (11) arrayed in one row and the plurality of terminal receiving chambers (11) arrayed in the other row.

An electrical feedthrough (1) is provided for improving the thermal properties and the electromagnetic compatibility (EMC) and also for simplified production of a medical instrument (7), in which electrical feedthrough individual contact pins (4), which are guided through a glass body (2) in a housing (20) of the instrument (7), are electrically connected to one another by a pluggable plug element (5), preferably in the form of a sheet metal part. Here, the plug element (5) firstly provides high thermal and electrical conductivity and secondly provides a shielding area that effectively prevents the input coupling of electromagnetic radiation. Preferably, the plug element (5) is formed in such a way that it independently develops a holding force for securing itself to the contact pins (4).

A position assurance apparatus, which is used for a connector assembly connected to a signal circuit are provided. The connector assembly comprises a first connector and a second connector, which are connected in pairs, wherein the first connector is connected to the signal circuit, and the second connector is inserted in the first connector. The position assurance apparatus comprises a first connecting portion and a second connecting portion, which are electrically connected to each other. The first connecting portion and the second connecting portion are configured to be electrically connected to the signal circuit by means of the first connector, so as to turn on the signal circuit when the first connector and the second connector are inserted in place.

A connection assembly includes a first housing part, a second housing part pluggable with the first housing part, and a joint connector held between the first housing part and the second housing part. The first housing part has a plurality of contact element receptacles and a plurality of latching elements. The latching elements latch a plurality of contact elements in the contact element receptacles. The second housing part has a locking section locking one of the latching elements in a latching position. The joint connector connects at least two of the contact elements.

A cam-type wire connector includes a housing, a conductor, and a lever. The housing has a plurality of insertion holes; the conductor comprises a conductive member and a leaf spring, the leaf spring has a carrier plate and a wire clamping portion that is formed with a plurality of windows. Wherein an elastic member is formed with the wire clamping portion for blocking the window; the lever has an operating portion and a toggle portion for cooperating with the leaf spring, the operating portion is constructed with a cam to allow the lever to swing without a fixed axis. When the lever is changed from an initial position to an actuate position, the elastic member is moved away from the carrier plate and an insertion channel is formed for allowing the wire to enter the window. The insertion channel is located in the interval between the second positioning surface and the fixed surface.
