The invention provides a lithium-ion secondary battery which comprises a shell, a cap component used for sealing the shell in an insulating way, and a battery cell and electrolyte that are arranged in a cavity defined by the shell and the cap component, wherein a first pole ear and a second pole ear are led out from the battery cell; the first pole ear is electrically connected with the shell, and the second pole ear is electrically connected with the cap component; the cap component comprises an electric connection component and a sealing ring arranged at the outer side of the electric connection component; the electric connection component comprises a positive temperature coefficient (PTC) thermistor protector, an anti-explosion piece and an upper cap which are sequentially and electrically connected; the PTC thermistor protector is positioned between the second pole ear and the anti-explosion piece; the lower surface of the PTC thermistor protector is electrically connected with the second pole ear, the central part of the upper surface of the PTC thermistor protector is electrically connected with the lower concave part in the centre of the anti-explosion piece, and the edge around the upper surface of the PTC thermistor protector is provided with an insulating washer so as to be insulated with the edge around the anti-explosion piece; and PTC thermistor protector is provided with a vent hole. The lithium-ion secondary battery has higher safety performance and sealing performance, the internal structure of the battery is simplified, and the internal space of the battery is effectively utilized.

The present invention addresses the problem of providing a plastic cell that maintains conductivity without losing sealability even when a plastic substrate is deformed into a free shape having an uneven surface or a curved surface, and a method for manufacturing the plastic cell. A plastic cell according to the present invention has, in this order: a first plastic substrate; a first transparent conductive layer; a fluid layer; a second transparent conductive layer; and a second plastic substrate. The plastic cell also has sealing part that includes a portion of the first plastic substrate orthe second plastic substrate, wherein the portion of the first plastic substrate or the second plastic substrate is deformed and seals the fluid layer. The sealing part has: a first sealing section that disconnects passage of electric current between the first transparent conductive layer and the second transparent conductive layer; and a second sealing section that allows passage of electric current to either the first transparent conductive layer or the second transparent conductive layer.

A flow spinning device, comprises a revolving cup housing in negative pressure, and a rotation spinning cup is in the housing. To reveal the spinning cup, a swing housing can swing from the revolving cup is located, and is close to the revolving cup housing. The spinning cup stops rotating by a brake lever when the swing housing is closed. A interlock device is connected to the brake lever, to swing the make position of outer cover and remove the interlocking by way of handling the brake lever. A guiding parts is located on the swing housing, and plays the direction face of fixed revolving cup stopper application position on its subsides when the swing of swing outer cover is leaned on and is lain in the brake lever to one. Besides the interlock, an interlock which is drived alone is still located. So that the revolving cup is sealing well, and avoid the unexpected operation.

The invention provides a cable pipeline sealing module. The cable pipeline sealing module comprises a base material, a rubber diaphragm, an expansion unit material and a blockage core rod. The cable pipeline sealing module in the invention has the performances that: (1), redundancy design is supported; therefore, a sealing system using the sealing module has the expansion capability in a design interval; and an expansion space can be reserved for cable or pipeline upgrading and reconstruction; (2), installation is simple and convenient; and a convenient condition is provided for later maintenance and cable inspection; (3), the sealing performance cannot be reduced by change of the cable or pipeline size tolerance; (4), the module has excellent air aging or oil resisting performance; and (5), the sealing performance when a cable or pipeline passes through a container in a low-voltage container can be improved; and the module can work in a high-temperature and ozone environment for a long time.

An object of the present invention is to provide a plastic unit that maintains electrical conductivity without losing sealing properties even when a plastic substrate is deformed into a free shape having unevenness or a curved surface, and a method for manufacturing the same. The plastic unit of the present invention has a first plastic substrate, a first transparent conductive layer, a fluid layer, a second transparent conductive layer, and a second plastic substrate in sequence, and also has a sealing part, and in the sealing part, the first plastic substrate or the second plastic A part of the substrate deforms to seal the fluid layer, and includes a part of the first plastic substrate or the second plastic substrate, and the sealing part has: a first sealing part that disconnects the first transparent conductive layer and the second transparent conductive layer; and the second In the sealing part, any one of the first transparent conductive layer and the second transparent conductive layer is energized.
