Embodiment
See Fig. 1 ~ 6, the utility model embodiment is provided with housing 1, extension spring 2, door closure 3, upper cover 4, sliding rail groove 12 is provided with in housing 1 inner bottom part side, sliding rail groove 12 is provided with groove grab 11, housing 1 inner bottom part is provided with interior grab 13, and door closure 3 puts into sliding rail groove 12, and the back side of door closure 3 is provided with door closure grab 31, the front of door closure 3 is provided with convex tendon 32, and convex tendon 32 pushes door closure 3 aside for USB plug; One end 21 of extension spring 2 is hooked on door closure grab 31, and the other end 22 of extension spring 2 is hooked on grab 13, and upper cover 4 covers on housing 1 and door closure 3, and the correcting muscle 42 be located on upper cover 4 guides door closure 3 to enter chute 41; After assembling, convex tendon 32 protrudes housing 1, to install upper cover 4 on corresponding printed board device bonnet, makes correcting muscle 42 guide door closure 3 to enter chute 41.
Below provide operation principle of the present utility model:
Housing is provided with sliding rail groove, groove is established a grab, also establishes a grab nearby from grab.Power transmission when door closure front being established convex tendon push door closure aside for USB plug.Extension spring 2 one end 21 on grab 31 hook of door closure 3, mobile door closure 3 makes the extension spring other end 22 hook the grab 13 of housing 1, pull door closure 3 that door closure 3 is put into housing 1 chute 12, under the chute 12 and the acting in conjunction of extension spring 2 pulling force of housing 1, door closure 3 upward sliding the opening of closure shell 1, now door closure 3 grab 31 slips in the grab 11 of housing 1, in extension spring 2, under the acting in conjunction of grab 11 and grab 31, various shake also unlikely door closure 3 is dropped from housing 1, after installing phase printed board device, cover upper cover 4, correcting muscle 42 on upper cover 4 can guide door closure 3 to enter chute 41.Having assembled rear convex tendon 32, to protrude housing 1 a bit of to use USB plug to push door closure 3 aside.
Below provide functional analysis of the present utility model:
Insert USB: hand-held usb data line end, USB plug iron-clad is pushed down door shield to setting aside, after pushing the limit, data wire pushes away inward, if cannot insert (judge USB direction anti-), then USB plug is rotated 180 ° and repeats said process again and can insert.
Automatic door-closing: after USB plug is extracted outward, door closure, under tension spring tension effect, is closed automatically.
