Abstract: The present invention discloses an electrically conductive module of a solar cell terminal box. The electrically conductive module comprises an insulation body, conducting strips and a diode chip, wherein there are two and only two conducting strips. The two conducting strips are electrically connected through the diode chip. The diode chip is located inside the insulation body. Each of the two conducting strips is provided with a through hole. The two side edges, which are fixed with the conducting strips, of the insulation body overlap with the through holes. A connection region between the insulation body and each of the conducting strips is only a region between the end portion of the corresponding through hole and the edge of the conducting strip. A part of each through hole is located inside the insulation body, and the remaining part of the through hole is located outside the insulation body and forms an enclosed busbar welding hole together with two side edges of the insulation body.

Abstract: Techniques for automatically grouping users in a network community are described herein. The disclosed techniques include receiving at least one virtual resource from a user; determining that a virtual identity has a value parameter equivalent to the at least one virtual resource in response to a first operation triggered by the user; sending the virtual identity to a resource repository associated with the user; presenting the virtual identity in a first predetermined area in response to detecting a second operation triggered by the user; determining whether at least one group has a same attribute as the virtual identity displayed in the first predetermined area; and adding the user into the at least one group in response to a determination that the at least one group has the same attribute as the virtual identify.
