A lock mechanism includes: a lock portion that protrudes from a ceiling wall (wall portion) of a cover and has a locking claw provided on a tip side; a lock receiving portion provided in a case and formed with a locking hole; and a flexible deformation portion which is a portion of a predetermined range in the vicinity of the lock portion on the ceiling wall (wall portion) of the cover and has flexibility higher than a portion outside the predetermined range, and is bent such that the lock portion is tilted so that the locking claw gets over an edge of the locking hole when the locking claw is locked to the locking hole, and after the locking, biases the lock portion in a pulling direction that pulls the locking claw together with the locking hole by a restoring force of bending.

A bus bar assembling structure includes a resin block main body for an electronic component block, a first bus bar, and a second bus bar. The resin block main body includes a bus bar assembling portion. The first bus bar and the second bus bar are accommodated in the bus bar assembling portion. The first bus bar has a first pushing portion that is pushed when the first bus bar is accommodated in the bus bar assembling portion, the first pushing portion being a bent piece. The first pushing portion has a through hole or a notch. The second bus bar has a second pushing portion that is inserted into the through hole or the notch and is disposed at a position corresponding to a position of a pushed surface of the first pushing portion.

Provided is a coupling structure of a bus bar equipped in a power part. The coupling structure of the bus bar includes a female type bus bar and a male type bus bar respectively coupled to different elements of the power part, wherein the female type bus bar is fitting-coupled to the male type bus bar. In the coupling structure of the bus bar, since bus bars of high voltage elements are connected to each other by a connecting method instead of a conventional bolting coupling structure, the miniaturization effect and cooling effect of an inverter may increase, and moreover, a tool used to couple bus bars may be omitted, thereby enabling power parts to be easily disposed.

A high current DC dispersing and converging connector comprises a dispersing and connecting terminal, a sheath I, a converging and connecting terminal and a sheath II, the dispersing and connecting terminal comprises three connecting ends I and a connecting end II; two connecting ends I are symmetrically fixed to the connecting end II; the sheath I is provided with three inserting ports I and an inserting port II; the sheath I is sleeved on an outer surface of the dispersing and connecting terminal; the tail of the connecting end II is provided with an inserting groove; the converging and connecting terminal is an umbrella-shaped copper-aluminum terminal; the sheath II is provided with two connecting ports; the sheath II is sleeved on an outer surface of the converging and connecting terminal; when the umbrella-shaped end is inserted into and fixed with the inserting groove, the inserting port II of the sheath I is inserted into and fixedly connected with the connecting port of the sheath II; and a seal ring is arranged at a contact position where the inserting port II and the connecting port are contacted. By improving the structure of the existing high current DC single-input and single-output connector, the solution reduces the convergence box, saves a connection space, makes processing more convenient, and also reduces processing time.

A method for producing a contact element includes producing a shaped body having a rectangular main body, a current tapping lug, and an intermediate lug, wherein the main body has first and second longitudinal sides opposite one another in a vertical direction and which respectively extend with a first length in a first horizontal direction, wherein the current tapping lug protrudes away from the first longitudinal side in the vertical direction and extends in the first horizontal direction over a second length which is less than the first length, and wherein the intermediate lug protrudes away from the first longitudinal side in the vertical direction and extends in the first horizontal direction over a third length less than the first length. The intermediate lug is bent over such that at least one portion of the lug comes to lie offset parallel to the main body in a second horizontal direction.

The present invention relates to an electric track system which can accommodate various appliance module using magnetic positioning. It supplements the missing functions of the current electric tracks, i.e., permitting the mixed use of the track-based fans and lights. This newly designed track can also be mounted to the wall for safe use of various electric appliances. The electric track system with magnetic positioning provides great flexibility, personal comfort and energy efficiency in both air circulation and room illumination for commercial and residential environments. With this system, various electric appliances can be mounted onto the track in a safe and quick way. A magnetic telescopic control rod is used to adjust the positions of the electric appliances in the ceiling-mounted track, like fans and lights. It brings safety and convenience to everyday life at affordable cost.

A multi joint junction having a plurality of selectively adaptable female well interfaces. Each of the well interfaces can have a generally uniform shape, size, and/or configuration such that each well interface is configured to generally interchangeably receive the same sized and/or shaped mating male connector or contact interface. The interfaces of the multi joint junction can also be limited to female contact interfaces, and not include any male connectors or contact interfaces. Such a configuration can provide a degree of modularity that can improve the ease with which the multi-point junction can be adapted to conform to different demands, applications and/or system configurations.

A bus bar for a printed wiring board assembly has a distribution portion and a supply portion. The supply portion has a socket contact that is in electrical communication with the distribution portion without an intervening joint portion to limit electrical resistance between a supply plug seated in the socket contact and the distribution portion of the bus bar. Printed wiring board assemblies, power distribution assemblies, and methods of making printed distribution assemblies are also described.

The battery module includes: a cell assembly; and an improved bus bar assembly to provide electric connection between a plurality of secondary batteries of the cell assembly, wherein the bus bar assembly includes: a first insulating frame having one or more insertion portions and including an electrically insulating material; a second insulating frame mounted on the front surface of the first insulating frame and including an electrically insulating material; a first bus bar mounted on the first insulating frame, contacting one of the plurality of electrode leads inserted into each of the one or more insertion portions, and including an electrically conductive material; and a second bus bar mounted on the second insulating frame, contacting one of the plurality of electrode leads inserted into each of the one or more insertion portion, and including an electrically conductive material.
