Abstract
The utility model discloses a kind of expandable type bilayer wiring board, including stacked upper wiring board and lower wiring board up and down, connected between upper wiring board and lower wiring board by the conductive hinge connection of exterior insulation, upper wiring board with the circuit connected in series of lower plug wire intralamellar part；A groove for accommodating the cord with socket is offered on the shell of lower wiring board; when upper wiring board and stacked lower wiring board; the groove is between upper wiring board and lower wiring board; safety warning light is additionally provided with the lower wiring board; overvoltage crowbar is provided with lower wiring board; instantly the voltage load of wiring board exceedes the threshold value that overvoltage crowbar is set, safety warning light flicker alarm.The utility model principle is simple, using reliable convenience, has very high economic and practical.
Description
Technical field
The utility model is to be related to a kind of wiring board, concretely relates to a kind of expandable type bilayer wiring board.
Background technology
Wiring board on the market at present, the regular length such as it is mostly, and it is unsuitable long, in case numerous cord with sockets tangle
To together, fire incident easily occurs or trips.When in the wild or mountain area is tested, often due to wiring board limited length,
Need multiple wiring boards to connect to carry out drawing electricity, it is very inconvenient.Therefore, in order to meet the needs of this respect, it is necessary to existing plug wire
Plate carries out structure and apparent improvement.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of expandable type bilayer plug wire
Plate.
In order to solve the above-mentioned technical problem, the utility model is to be achieved through the following technical solutions：
A kind of expandable type bilayer wiring board, including stacked upper wiring board and lower wiring board up and down, upper wiring board is with
Connected between wiring board by the conductive hinge connection of exterior insulation, upper wiring board with the circuit connected in series of lower plug wire intralamellar part；
Power switch, several sockets and cord with socket are provided with upper wiring board；If it is also equipped with lower wiring board
A socket and cord with socket are done, a groove for accommodating the cord with socket, upper plug wire are offered on the shell of lower wiring board
When plate and stacked lower wiring board, the groove is additionally provided with peace between upper wiring board and lower wiring board on the lower wiring board
Full warning lamp, overvoltage crowbar is provided with lower wiring board, the voltage load of wiring board is set more than overvoltage crowbar instantly
The threshold value put, safety warning light flicker alarm.
Compared with prior art, the beneficial effects of the utility model are：
The utility model principle is simple, easy to use.Under normal circumstances, wiring board can be at not deployed working condition, make
Often used for family expenses with wiring board；When due to electrical appliance increase and socket it is inadequate when, lower wiring board is deployable, increase socket number
Amount, it can reduce due to the trouble that socket is inadequate and brings, it is convenient and practical；And operation in the wild etc. needs cord with socket length to increase
The occasion that adds is in use, after the expansion of lower wiring board, because cord with socket takes out from cavity so that there is band at wiring board two
Plug electric wire, it is convenient to access power supply from either end.In addition, when power consumption dramatically increases after expansion, safety warning light again may be used
Warning function is played, to prevent the generation for the contingency for carrying overtension due to wiring board and bringing.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is deployed condition schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Such as Fig. 1, a kind of expandable type bilayer wiring board, including stacked upper wiring board and lower wiring board up and down, upper plug wire
By the conductive hinge connection of exterior insulation between plate and lower wiring board, the circuit connected in series of upper wiring board and lower plug wire intralamellar part connects
Connect；
Such as Fig. 2, when double-deck wiring board deploys, lower wiring board 4 and upper wiring board 1 are in juxtaposition, on upper wiring board
It is provided with power switch 2, several sockets 3 and cord with socket 5；Several sockets 3 are also equipped with lower wiring board 4 and with slotting
Head electric wire 5, offers a groove for accommodating the cord with socket 5, upper wiring board 1 and lower plug wire on the shell of lower wiring board 4
When plate 4 is stacked, the groove is additionally provided with security warning between upper wiring board 1 and lower wiring board 4 on the lower wiring board 4
Lamp 6, overvoltage crowbar is provided with lower wiring board 4, the voltage load of wiring board 4 exceedes what overvoltage crowbar was set instantly
Threshold value, the flicker alarm of safety warning light 6.
It is powered in use, the cord with socket 5 of the cord with socket 5 of upper wiring board 1 or lower wiring board 4 is inserted into power supply.
General principle, principal character and use advantages of the present utility model, the technology of the industry has been shown and described above
Personnel are it should be appreciated that the utility model is not restricted to the described embodiments, before the spirit and scope of the utility model is not departed from
Put, the utility model also has various changes and modifications, and these changes and improvements both fall within claimed the utility model
In the range of.In addition, the undeclared part being related in the utility model is same as the prior art or is realized using prior art.
