The housing has a locking portion, which is positioned within the range between the circuits positioned at the outermost ends in the strip width direction of the flat-type conductor and is lockable to the counterpart electrical connector, and a holding space, which holds the retainer along with the front end section of the flat-type conductor, the front end section of the flat-type conductor has formed therein a pass-through portion extending through the flat-type conductor in the thickness direction of said flat-type conductor at a location at least partially overlapping with the locking portion in the strip width direction, and the retainer has a protrusion that protrudes in the thickness direction of the flat-type conductor and enters the pass-through portion of the flat-type conductor, thereby making it possible to limit the rearward movement of the flat-type conductor with the help of said protrusion.

A connector includes a housing including a terminal accommodation chamber, a terminal fitting including a locking hole and to be inserted into the terminal accommodation chamber from behind the housing, and a locking lance for retaining the terminal fitting inserted into the terminal accommodation chamber. The locking lance is cantilevered forward and includes a body portion resiliently displaceable in a direction intersecting an insertion direction of the terminal fitting and a projection projecting from the body portion toward the terminal fitting and configured to enter the locking hole when the terminal fitting is inserted into the terminal accommodation chamber. A width of the projection is smaller than that of the locking hole. A maximum width of the body portion is larger than the width of the projection. A part of the body portion connected to the projection is formed with a guiding portion gradually reduced in width toward the projection.

A connector 10 includes a terminal fitting 11, a housing 12, a seal member 13 and a mounting member 14. The terminal fitting 11 is connected to a wire 80. The seal member 13 includes a seal hole 52 through which the wire 80 is passed in a liquid-tight manner. The mounting member 14 holds the seal member 13 by sandwiching the seal member 13 between the housing 12 and the mounting member 14. The mounting member 14 is in contact with the seal member 13 and movably mounted on the housing 12.

The invention relates to a plug-in connection, comprising a plug connector having a plug connector housing (1) and comprising a mating plug connector that can be plugged together with the plug connector, wherein the plug connector has a superstructure (4) and the superstructure (4) accommodates a locking element (8) in a preliminary latching position and a final latching position, wherein the plug connector has first latching means and the locking element (8) has first latching means corresponding thereto and the mating plug connector has further latching means and the locking element (8) has further latching means corresponding thereto, wherein the locking element (8) is first fastened to the plug connector in the preliminary latching position by means of the first latching means corresponding to each other before the mating plug connector is inserted into the plug connector, and the further latching means corresponding to each other are actuated by means of the insertion of the mating plug connector into the plug connector, whereby the locking element (8) can be moved into the final latching position thereof, characterized in that the plug connector housing (1) and the locking element (8) have third latching means corresponding to each other, by means of which additional locking of the locking element (8) to the plug connector occurs when the locking element has been moved into the final latching position thereof.

A power tool including a housing that has a battery pack receiving portion configured to receive an interface of a battery pack, device contacts extending from the housing and configured to mechanically and electrically engage with the battery pack, and a latching mechanism supported by the housing and including an actuator and a latch member configured to selectively engage the interface of the battery pack. The actuator is pivotable to operatively pivot the latch member.

The utility model discloses an electrical connector for Christmas lamp trees which comprises an upper and a lower connecting base, first columnar electrodes and elastic devices are arranged in the upper connecting base, second arc-shaped electrodes are arranged in the lower connecting base, and the elastic devices cause the first electrodes to tightly abut against the second electrodes. The first columnar electrodes and the second arc-shaped electrodes form a point-to-surface contact, so that the reliability of electrical connection is increased greatly, allowing a Christmas lamp tree to be universal to high and low voltages. Moreover, sufficient contact between upper and lower layers and natural effect of the Christmas lamp tree can still be ensured even if the Christmas lamp tree is subjected to an external force, and multiple sets of first and second electrodes are electrically connected in one-to-one correspondence, leading to diversified functions of the Christmas lamp tree.

A fixture is sized to be inserted into an electrical junction box having a socket. The fixture has a plug with conductive terminals that are mateable with the socket to connect the fixture to an electrical signal connected to the socket. An end of the fixture with the plug is inserted into the junction box to mate with the socket. A release latch extends from the plug so that an end of the latch is not recessed within the junction box, and can be pushed to release the plug and fixture for removal. The socket is attached to extension arms that are attachable to the junction box, so that the socket can be positioned at the correct height within the box to properly mate with the plug of the fixture after insertion.

A shelving system having a detached power supply apparatus includes at least a hollow vertical shelf rail, at least a bus bar inserted into the vertical shelf rail, and at least a detached power supply apparatus inserted in the vertical shelf rail and electrically connected to the bus bar. Each of the vertical shelf rails includes at least a punched hole, and two locating protrudes. Each of the bus bar includes a slot, and two current conductors. The slot includes a carrier surface, and a track abutting surface. Each of the detached power supply apparatus passes through the punched hole and is inserted between the carrier surface and the track abutting surface. Each of the detached power supply apparatus includes two push-in resilient ball head plungers, a receiving surface, an abutting surface, and two reeds. The abutting surface is engaging with the track abutting surface.
