Referring to fig. 1-6, an embodiment of a plug protective sleeve 200 of the present invention is shown. The plug shroud 200 is used to protect the plug 100. As shown in fig. 1 and 2, the plug 100 includes two pins 110 and a ground post 120. The pins 110 in this embodiment are in the form of inserts.
Specifically, referring to fig. 3-5, the plug sheath 200 includes two pin holders 210, a first connection 220, a ground post holder 230, and a second connection 240.
The bottom surface of the pin fixing part 210 is formed with insertion grooves 211 longitudinally extending in the height direction of the pins 110, and the insertion grooves 211 are used for fixing and protecting the pins 110 of the plug 100. The pin fixing part 210 has a certain height, and the depth of the insertion groove 211 is preferably equal to the height of the pin 110.
The first connecting portion 220 is disposed between the two pin fixing portions 210, extends longitudinally along the height direction of the pin 110, and connects the two pin fixing portions 210.
A ground post fixing portion 230 having a receiving groove 231 longitudinally extending in a height direction of the ground post 120; the receiving groove 231 is used to fix and protect the ground post 120.
The second connecting portion 240 is perpendicular to the first connecting portion 220, and the second connecting portion 240 also extends longitudinally along the height direction of the pin 110 to connect the ground post fixing portion 230 and the first connecting portion 220. In the present embodiment, the second connection portion 240 is connected to an intermediate position of the first connection portion 220. The first connection portion 220 and the second connection portion 240 have a certain height, and can perform a supporting and fixing function.
Referring to fig. 6, when the ground stud 120 contacts or impacts other components, such as a pad or a panel, the force is applied in the direction shown by the dotted arrow in fig. 6, and the second connecting portion 240 and the ground stud fixing portion 230 can provide a counter supporting force, shown by the solid arrow in fig. 6.
The plug protective sleeve 200 can protect the pins 110 of the plug 100, and the grounding post fixing part 230 is additionally provided for supporting, so that the overall installation of the power plug 100 is not influenced, and the force applied by the grounding post 120 colliding with a cushion block and the like in an unstable state can be transferred to the overall sheath for supporting, and the probability of root fracture and falling off is reduced.
In this embodiment, the bottom end of the insertion groove 211 is open, and the top end is closed, so as to better protect the pin 110.
Preferably, a side of the ground post fixing portion 230 away from the first connecting portion 220 is open, that is, the ground post fixing portion 230 may be a semi-closed structure, which is simple in structure. Further, since the grounding post 120 is not charged, the upper end of the accommodating groove 231 may not be closed, i.e., both the upper and lower ends are open. In other embodiments, the ground pin fixing portion 230 may also be designed to be a closed structure similar to the structure of the pin fixing portion 210.
In the present embodiment, referring to fig. 2 specifically for the structure of the ground pillar fixing portion 230, the ground pillar fixing portion 230 is preferably a semi-circular ring structure, and the inner groove of the semi-circular ring forms the receiving groove 231. The ground post fixing part 230 of the semi-torus structure can be well fitted to the cylindrical ground post 120. In other embodiments, the cross-section of the ground post fixing portion 230 may also be a semi-rectangular ring, a portion of an elliptical ring, or the like.
In order to improve the compatibility of the plug protection case 200, the insertion slot 211 in this embodiment is provided with a first insertion slot 2111 and a second insertion slot 2112 which are communicated with each other, and can be adapted to two plug types. The first slot 2111 and the second slot 2112 are perpendicular to each other in this embodiment.
At least one side surface of the insertion groove 211 is provided with a limit protrusion 212. When the pins 110 are inserted into the insertion grooves 211, the pins 110 are pressed by the limiting protrusions 212, so that the friction force between the pins 110 and the limiting protrusions 212 can be increased, and the plug protection sleeve 200 can be tightly sleeved on the plug 100. Two limiting protrusions 212 are disposed on opposite sides of the first slot 2111, and two limiting protrusions 212 are disposed on opposite sides of the second slot 2112. The top of the position-limiting protrusion 212 is an inclined surface to facilitate the insertion of the pins 110.
In this embodiment, the plug protection cover 200 is an integrated structure, such as formed by injection molding of insulating plastic, and has a simple structure and a low cost. In the embodiment, the first connecting portion 220, the second connecting portion 240 and the ground pin fixing portion 230 have the same height, which is slightly less than the height of the pin fixing portion 210, so as to provide a better supporting force.
The bottom surface of the second connecting portion 240 is further formed with a hollow groove 241 to reduce manufacturing materials and cost.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed in the appended claims.
