SUMMERY OF THE UTILITY MODEL
The utility model aims at designing a power plug, making it realize participating in and the electric connection between the circuit board does not need conductive parts such as wire, conveniently dismantles the suitability that the circuit board maintained and improved the circuit board simultaneously.
In order to achieve the above object, the utility model provides a following technical scheme:
a power plug comprises a shell, a shell cover, pins and a circuit board, wherein the shell is matched with the shell cover, and an inner cavity is formed in the shell; the pins are fixedly connected with the shell according to the national plug layout standard; the upper end and the lower end of the plug pin are respectively a conductive end and an insertion end, the insertion end is positioned outside the lower part of the shell, and the conductive end is positioned in the inner cavity of the shell; the circuit board is arranged in the inner cavity of the shell, and a metal elastic sheet is fixedly arranged on the circuit board; the metal elastic sheet comprises a conducting sheet, a bottom sheet and two clamping sheets; the conducting sheet is fixedly connected to the lower surface of the bottom sheet, and the metal elastic sheet is electrically connected with the circuit board through the conducting sheet; the bottom plate is provided with a through hole, and the aperture of the through hole is larger than the cross-sectional area of the conductive end; the two clamping pieces are arranged on the upper surface of the bottom plate in a bilateral symmetry manner, and the clamping pieces are elastically connected with the bottom plate; the conductive end of the pin penetrates through the through hole and is positioned between the two clamping pieces and is in contact with the clamping pieces in a fitting manner.
Furthermore, support plates are arranged on two sides of the inner cavity of the shell. In consideration of the design of the circuit board, the pins of the circuit component are inserted into the upper surface of the circuit board, and then the pins are fixed to the circuit board by using solder on the lower surface of the circuit board. In order to avoid the abrasion of the soldering tin caused by the fact that the lower surface of the circuit board is attached to the upper surface of the inner cavity of the shell after the circuit board is placed in the inner cavity of the shell. Therefore, the circuit board is heightened by the supporting plate, and the lower surface of the circuit board is prevented from being in direct contact with the upper surface of the inner cavity of the shell, so that soldering tin abrasion is avoided.
Further, a rubber layer is arranged on the upper surface of the inner side of the shell cover. After the shell and the shell cover are combined, the rubber layer of the shell cover is inconsistent with the circuit parts on the circuit board, so that the circuit board is simultaneously pressed from the upper side and the lower side, and the circuit board is prevented from shaking in the plug, and the circuit parts are prevented from being out of order due to impact. Because the rubber layer belongs to the elastic material, can not excessively extrude circuit part, lead to circuit part impaired.
Furthermore, the lower end of the shell is provided with a fixing boss, and the power inserting end of the pin penetrates through the fixing boss and is arranged outside the lower part of the shell.

When the power plug is inserted, the elastic salient points on the elastic rubber are inserted into the socket holes along with the pins due to the characteristic of elastic deformation. When the power plug enters the socket hole, the elastic salient points elastically deform to the original size to block the hole opening of the socket, so that the power plug is difficult to pull out from the socket hole, and the purpose of firmly inserting the power plug on the socket and preventing loosening is achieved.
Furthermore, the elastic rubber is of a frustum pyramid structure, and the bottom area of the elastic rubber is gradually reduced along the direction of the plug-in end. Along with power plug inserts into toward the jack, the total cross-sectional area of participating in and elastic rubber will be bigger and bigger, but the cross-sectional area of jack can not change, because elastic rubber has the elastic deformation characteristic, power plug still can continue to insert into toward the jack to lead to power plug will insert tighter and tighter more, tightness more difficult pine takes off, further realizes the purpose of anti-loosening.
Compared with the prior art, the beneficial effects of the utility model are that:
the plug pins are fixed on the shell, the circuit board is arranged in the inner cavity of the shell, the circuit board is connected with the plug pins through the metal elastic pieces fixed on the circuit board, the metal elastic pieces transmit current to the circuit board through the plug pins, and conductive parts such as wires are not needed, so that the problem that the wires are broken in the using process is not needed.
The specific connection mode of the metal elastic sheet and the pin is realized by clamping two clamping sheets of the metal elastic sheet on two sides of the conductive end of the pin through action. Therefore, when the circuit board is required to be positioned, the circuit board can be directly pulled out from the pins, and the circuit board is convenient and quick. Meanwhile, the two clamping pieces clamp the pins simultaneously due to the elastic action, so that the fixation between the circuit board and the pins is not limited to the pins of the conductive end with a single size, the applicability of the circuit board is improved, and the circuit board can be suitable for the pins with various sizes.
