Abstract
The utility model discloses a screw type plug-and-socket, which comprises a socket outer shell (1) and a plug outer shell (10), wherein a socket nut (2) is fixed in the socket outer shell (1), the socket nut (2) is connected with a socket terminal device (3), a plug nut (9) is fixed in the plug outer shell (10), the plug nut (9) is connected with a plug terminal device (5), the top portion of the plug outer shell (10) is fixed with an insulation sheet (7), a screw rod (4) passes through the insulation sheet (7) to be connected with the plug nut (9) through screws and passes through the plug outer shell (10) and the socket outer shell (1) to be connected with the socket nut (2) through screws, the top portion of the screw rod (4) is provided with an insulation sleeve (6), and a plug cap (8) which is connected with the plug outer shell (10) is arranged above. The screw type plug-and-socket has the advantages of simple structure, safe and reliable utilization and long service life, and cannot reduce contact area due to heating between plugs and sockets.
Description
Technical field
The utility model belongs to the electric connection technology field, particularly a kind of combiner of plug and socket.
Background technology
Connection between the plug and socket commonly used is to use in circle (or flat) the plug insertion socket middle concave copper sheet, relies on plug and contacting of spill copper sheet that the power supply in the socket is drawn.When plug insertion socket, the elastic force that relies on the spill copper sheet in the socket that contacts of plug and socket clamps that plug realizes.This connected mode, the contact area of plug and socket spill copper sheet is little, and in use, because the factor such as rough of the heating distortion of spill copper sheet and plug surface, cause the contact area of plug and socket spill copper sheet further to be dwindled, to such an extent as to the contact resistance of plug and socket increases, caloric value increases during use, causes the damage of plug and socket.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of simple in structure, safe and reliable, the life-span is long screw-type plugs and sockets, to overcome deficiency of the prior art.
The technical solution of the utility model: it comprises jack housing and plug body, at the jack housing internal fixation socket nut is arranged, and the socket nut is connected with the socket termination; At the plug body internal fixation plug nut is arranged, plug nut is connected with the plug bond device, and the top of plug body is fixed with insulating trip; Screw rod passes insulating trip and is connected, passes plug body with plug nut by screw thread and be connected with the socket nut by screw thread with jack housing; The screw rod top is provided with insulating case, and its top is provided with the bayonet cap that is connected with plug body.
Described plug bond device, socket termination are copper lug.
The material of described socket nut, plug nut and screw rod is a copper.
Compared with prior art, the utility model is simple in structure, safe and reliable, can not reduce contact area between plug and the socket during use because of heating, prolong useful life greatly, be specially adapted to have the electric equipment (use the switch of himself to get final product power on/off, do not need to come deenergization) of Switching Power Supply with the mode of pulling up attaching plug.The utility model in use, can be because of the resistance heating of self in socket nut, plug nut and the screw rod because of there being electric current to flow through, junction pressure increases behind the expanded by heating, contact-making surface also increases thereupon, and himself resistance will diminish, and therefore is specially adapted to the bigger electric equipment of electric current and uses.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: in order to obtain conductive effect preferably, use socket nut 2 made of copper, plug nut 9 and screw rod 4, its quantity determines according to actual needs, can increase the height of socket nut 2, plug nut 9 according to demand or increase screw rod 4 diameters to increase its capacity, to satisfy user's demand; Use copper lug to make plug bond device 5 and socket termination 3.
As accompanying drawing 1, at jack housing 1 internal fixation socket nut 2 is arranged, socket nut 2 is connected with socket termination 3; At plug body 10 internal fixation plug nut 9 is arranged, plug nut 9 is connected with plug bond device 5, and the top of plug body 10 is fixed with insulating trip 7; Screw rod 4 passes insulating trip 7 and is connected, passes plug body 10 by screw thread and plug nut 9 and be connected with socket nut 2 by screw thread with jack housing 1; Screw rod 4 tops are provided with insulating case 6, and its top is provided with the bayonet cap 8 that is connected with plug body 10.
During use, bayonet cap 8 is opened, held insulating case 6 screw rod 4 is screwed in plug nuts 9 and the socket nut 2, covers bayonet cap 8 again and get final product.
