A hand holdable light comprises: a light body having a forward portion, a rearward portion, and a central portion between the forward portion and to the rearward portion; a light source proximate a forward end; and a switch for energizing the light source. The rearward portion has a non-circular cross-section; the switch is on the forward portion; and the central portion has a recess opposite the switch. The light is holdable by a hand with a finger or thumb proximate the recess and the other of a finger or thumb proximate the switch. A battery assembly comprises: a battery housing for receiving and connecting a battery; an electrical switch on a first end of the battery housing; and a pattern of electrical contacts on a second end of the battery housing, wherein ones of the electrical contacts are connected to the battery.

A power storage pack includes a plurality of power storage modules each including a power storage element group with a plurality of power storage elements having electrode terminals, and an external connection module electrically connected to the electrode terminals and including a short bus bar and a long bus bar for outputting power of the power storage element group, and an insulating member for insulating and holding the short bus bar and the long bus bar, the insulating member including a first unit for holding one end portion of the long bus bar and a second unit for holding another end portion of the long bus bar, the first unit has a first overlapping portion, the second unit has a second overlapping portion, and the first overlapping portion and the second overlapping portion have a variable length overlapping margin in which they overlap each other.

A wiring module to be attached to a plurality of power elements which store or generate power includes a bus bar connecting the power elements to each other or connecting the power element and a load to each other, an abnormality detection element detecting an abnormality of the power element, and an insulating protector holding the bus bar and the abnormality detection element. The insulating protector is integrally provided with a first holding shaft portion and a second holding shaft portion which position and hold the bus bar by fitting the bus bar there onto, and an element holding portion which position and hold the abnormality detection element by fitting the abnormality detection element there into.

Provided is a sensor including a first bus bar, a second bus bar, and a shunt resistor including a shunt resistor body part whose one end portion is bonded to the first bus bar and the other end portion is bonded to the second bus bar and a detection terminal extending from the shunt resistor body part.

Locking assemblies are provided for connecting to a stranded element. The locking assemblies include a housing with a receiving bore, locking bore, and aperture. The stranded element enters the housing through the receiving bore. A drive shaft can advance a locking element in the locking bore such that the locking element contacts the stranded element to apply a force to secure the stranded element to the locking assembly. Ends of the stranded element can be pushed by the locking element out of the housing through the aperture. The locking assemblies can be used for mechanical and/or electrical connections. Examples of stranded elements include electrical wires, mechanical stranded cables, rope, and other multi-strand materials.

A first coupling body is disposed as part of a housing body, has a bottom part, and has a first and a second vertical wall parts. A second coupling body is formed so as to cover a space between the first vertical wall part and the second vertical wall part in the bottom part inside the housing chamber. The holding mechanism includes a first projection projecting from a first end of the second coupling body toward the first vertical wall part side, a second projection projecting from a second end of the second coupling body toward the second vertical wall part side, a first through-hole that is formed in the first vertical wall part, and a second through-hole that is formed in the second vertical wall part, the first end covering the first vertical wall part, the second end covering the second vertical wall part.

A cooling lance is provided to cool an electrically conductive contact body. The cooling lance includes a lance body, a fluid line extending through the lance body, and a flexible cooling bladder positioned on an end of the lance body and in fluidic communication with the fluid line.

A battery clamp having a first inner metal battery clamp member having a handle portion and a clamp portion, a second inner metal battery clamp member having a handle portion and a clamp portion, a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp, and a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp. The first inner metal battery clamp member and/or the second inner metal battery clamp member having an inclined connection plate for connection with a battery cable, the inclined connect plate configured to allow a user to access the inclined access plate with a tool while avoiding interference with the handle portions of the battery clamp.

A battery clamp having a first inner metal battery clamp member having a handle portion and a clamp portion, a second inner metal battery clamp member having a handle portion and a clamp portion, a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp, and a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp. The first inner metal battery clamp member and/or the second inner metal battery clamp member having a battery cable connector configured to allow a user to access the battery cable connector with the user's fingers or a tool while avoiding interference with the handle portions of the battery clamp.
