Abstract
The utility model discloses an electric plug device, which comprises a signal wire, a power wire, an arranging needle and a plastic shell, wherein the power wire and the signal wire are respectively a multi-core wire composite cable, the core wires of the power wire and the signal wire are respectively connected with the arranging needle, the head of the arranging needle is exposed out of the plastic shell, the connection place between the signal wire and the arranging needle as well the connection place between the power wire and the arranging needle are positioned in the plastic shell, and the gap of the plastic shell is packed by pouring sealant. The plug device is completely packed in the plastic shell by the pouring sealant, thereby realizing the water-proof function and improving the connecting reliability of each component in the plug device due to the pouring sealant; the power wire and the signal wire are glued with the plastic shell by the pouring sealant, so that the interfaces are hard to become flexible; and the gap of the plastic shell is also coated by the pouring sealant, so that each component of the shell is hard to separate from each other and fall off.
Description
Technical field
The utility model relates to a kind of electrical plug device, relates in particular to a kind of electrical plug device.
Background technology
At present, the generally popular LED power supply of industry is to be connected by winding displacement with the signal plugging mode,, can not waterproof, run into conducting liquid and cause short circuit easily.
The utility model content
The technical problem that the utility model mainly solves provides a kind of electrical plug device of waterproof.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of electrical plug device is provided, described electrical plug device comprises holding wire, power line, row's pin and plastic casing, described power line and holding wire are the compound cable of split conductor, described power line is connected with row's pin respectively with the heart yearn of holding wire, row's pin syringe needle partly exposes plastic casing, described holding wire, power line is arranged in plastic casing with the junction of row's pin, described plastic casing and power line, the junction of holding wire, and the fastening of plastic housing sheet is sentenced the casting glue encapsulation.
Wherein, described electrical plug device comprises wiring board, and described row's pin is welded on the wiring board, and described holding wire and power line and wiring board weld, and links to each other with row's pin by wiring board, and described wiring board is arranged in plastic casing.
Wherein, described row's pin quantity doubles the quantity of power line and holding wire heart yearn, and every power line heart yearn is connected two row's pins with the holding wire heart yearn.
Wherein, described power line links to each other with the VH7 socket with the end that holding wire is not connected with wiring board.
Wherein, described row's pin is gold-plated row's pin.
Wherein, described electrical plug device is LED display device power supply or signal plug assembly.
The beneficial effects of the utility model are: the slit in the plug assembly described in the utility model is packaged among the plastic casing by casting glue, realized water-proof function, and casting glue has improved the reliability of the connection of each element in the plug assembly, because casting glue bonds together power line and holding wire and plastic casing, it is loosening that interface is difficult for, and place, the fastening slit of plastic casing also is covered with casting glue, and each parts of shell are not easily separated, come off.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 2, present embodiment provides a kind of electrical plug device, and described electrical plug device comprises holding wire, power line, in the present embodiment, for connecting up conveniently, the two is merged into a cable, general designation power supply signal line 1, described electrical plug device also comprises row's pin 3 and plastic casing 4, described power supply signal line 1 is the compound cable of split conductor, and described row's pin 3 is gold-plated row's pin, to strengthen the reliability that is electrically connected.
Described electrical plug device comprises wiring board 2, and described row's pin 3 is welded on the wiring board 2, as shown in Figure 2, has row's needle interface 6 on the wiring board on the wiring board 2.Each heart yearn 11 welds with wiring board 2 in the described power supply signal line 1, and links to each other with row's pin 3 by wiring board 2, and described wiring board 2 is arranged in plastic casing 4.Row's pin 3 syringe needles partly expose plastic casing 4, and described power supply signal line 1 is arranged in plastic casing 4 with the junction of row's pin 3, the junction of described plastic casing 4 and power supply signal line 1, and the fastening of plastic housing sheet is sentenced the casting glue encapsulation.
Described row's pin 3 quantity double the quantity of the heart yearn 11 of power supply signal line 1, and every heart yearn 11 connects two row's pins 3.The generally popular LED power supply of industry is to be connected by winding displacement with the signal plugging mode, and every road signal only is connected once with display device with power supply, has one tunnel loose contact promptly signal deletion or powering-off state can occur, does not have backup functionality.And present embodiment is on wiring board 2, and every heart yearn 11 all is connected with two row's pins 3, realizes the double copies functions with row's pin 3, has avoided influencing circuit working because of place loose contact.
The end that described power supply signal line 1 is not connected with wiring board 2 links to each other with VH7 socket 5.
The described electrical plug device of present embodiment is LED display device power supply or signal plug assembly.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
