Title:
ELECTRICAL CONNECTION DEVICE, TERMINAL BLOCK INCLUDING SAME, PHOTOVOLTAIC POWER GENERATION SYSTEM, AND ELECTRICAL APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2016/009804
Kind Code:
A1
Abstract:
An electrical connection device (100) includes a male portion having a head (21) and a body (24), the head (21) being provided with a groove for inserting a driver, and the body (24) being provided with a first guide hole (26a) and a second guide hole (26b), which are formed from the bottom end of the body (24) and which penetrate the body (24) in a spiral manner; a female portion (116) provided with a hole (118) into which the body (24) is inserted; an elastic portion (40) that is disposed on an outer circumference of the body (24) when the body (24) is inserted into the hole (118); and a movable body (30) that is disposed under the elastic portion and that is fitted into the first guide hole (26a) so as to penetrate the same when the body (24) is inserted into the hole (118). A first conductive member (50) and a second conductive member (60) are interposed between the top end of the elastic portion (40) and the head (21). With the movable body (30) fitted in the first guide hole (26a), as the head (21) rotates relative to the hole (118) up to a predetermined rotation angle, the movable body (30) contacting the bottom end of the elastic portion (40) moves upward, whereby the urging force of the elastic portion (40) increases. When the rotation angle of the head (21) relative to the hole (118) exceeds the predetermined rotation angle mentioned above, the movable body (30) fits into an end (29) of the second guide hole (26b), which is provided in a direction for decreasing the urging force and which communicates with the first guide hole (26a), whereby the rotary movement of the movable body (30) relative to the body (24) is suppressed.
