Provided is a connector wherein, when a plug is inserted in a socket, the plug is prevented from being erroneously inserted, and it is not necessary to rotate the plug to a great extent. A plug-in connector (1) is comprised of a pin plug (10) and a receptacle (20), and the pin plug (10) and the receptacle (20) are connected. A plurality of pin plug key protrusions (15) are spaced and arranged on a pin cover main body (14) of the pin plug (10) in the circumferential direction. A plurality of groups of a plurality of key grooves (28) spaced in the circumferential direction are arranged so as to be deviated from one another in the circumferential direction, in a socket cover (27) of the receptacle (20). A socket plug (30) may be used in place of the receptacle (20). As described above, there are a plurality of groups of grooves in the plug or the socket, and accordingly, the circumferential angle of the plug with respect to the socket can vary depending on the number of the groups of grooves. Therefore, the connector can reduce the twisting angle of a cable connected to the plug, and can reduce the load on the cable.
A connector apparatus is to be connected to an electrical appliance, and comprises a first connector that has a plurality of power-receiving terminals for receiving supply of power; and a second connector that is to be connected to a DC power supply, and that can be intermeshed with the first connector. The second connector comprises a plurality of power-feeding terminals that correspond to the plurality of power-receiving terminals of the first connector; and a switch member that is movable between a connection position for electrically connecting the power-feeding terminals with the DC power supply, and a cut-off position for cutting off the connection between the power-feeding terminals and the DC power supply.

Abrégé
A double floor structure capable of being adapted to the conditions of construction and the needs of users at low cost. A double floor structure (K) provided with support legs (1) which are provided on a lower floor and rows of beams which form an upper floor. The support legs (1) are each provided with an upper member (14) which supports a beam from the lower side, an intermediate member (13) which supports the upper member (14) from the lower side, and a lower member (12) which supports the intermediate member (13) from the lower side. The upper member (14), the intermediate member (13), and the lower member (12) consist of metallic, extruded shape material and are disposed in such a manner that the direction of the extrusion is aligned with the top-bottom direction.
Provided is a long-life manganese nonaqueous electrolyte cell of improved safety during cell malfunction. A cell (20) comprises a cylindrical container (7) having a base. The container (7) houses an electrode assembly (6) obtained by winding, around a separator (W5), a positive electrode that uses a spinel lithium-manganese composite oxide as the positive electrode active material and a negative electrode that uses a carbon material as the negative electrode active material. The electrode assembly (6) is immersed in an electrolyte obtained by adding LiBF4 as electrolyte to an organic solvent. 10 wt% of a phosphazene flame retardant is further added to the electrolyte. It is possible to render less likely ignition of the electrolyte and inhibit manganese elution during cell malfunction.

Disclosed is a lithium-ion battery which is highly safe and where fire resistance of a non-aqueous electrolyte during battery failure is maintained over a long period of time. In the lithium-ion battery, two types of organic solvent, EC and DMC, are used in a mixed organic solvent forming the non-aqueous electrolyte, and liquid fire retardants are added to the non-aqueous electrolyte: a phosphazene (A) with a boiling point close to the boiling point of EC, and a phosphazene (B) with a boiling point close to the boiling point of DMC. During battery failure, a separator dissolves, battery temperature rises due to an internal short circuit between the positive and negative plates, and EC and DMC each break down, and at that time, the phosphazenes (A, B), respectively having similar boiling points, break down and act as needed, allowing the fire resistance of the non-aqueous solution to be maintained over a long period of time, and ensuring the safety of the battery during battery failure.

Provided is a nonaqueous electrolyte cell with which it is possible to stabilize cell behavior during cell malfunction and ensure safety. A lithium ion secondary cell (20) comprises an electrode assembly (6) housed in cylindrical cell container (7) having a base. The electrode assembly (6) is obtained by winding a positive electrode plate and a negative electrode plate around a separator (W5). The positive electrode plate has aluminum foil (W1) as the positive electrode current collector. A positive electrode mix containing a lithium-transition metal composite oxide as the positive electrode active material is applied to both surfaces of the aluminum foil (W1) to form a positive electrode mix layer (W2). A flame retardant layer (W6) containing a flame retardant is formed on the surface of the positive electrode mix layer (W2). The negative electrode plate has rolled copper foil (W3) as the negative electrode current collector. A negative electrode mix containing a carbon material as the negative electrode active material is applied to both surfaces of the rolled copper foil (W3) to form a negative electrode mix layer (W4). The flame retardant agent decomposes under a high-temperature environment, such as when the cell malfunctions.
