Situations such as, and inserted sheet is assembled into inside connection framework and has greatly saved space, improves socket position on every PDU product
Quantity.
Embodiment 1
As illustrated, the present embodiment discloses a kind of preventing plug from dropping self-locking mechanism, including box-shaped connection framework 1 and two
Individual U-shaped inserted sheet 2, the centre of connection framework 1 set the hollow region 11 passed through to plug, and the relative both sides of connection framework are set
Bore passages 13 are equipped with, described bore passages are communicated by fluting 12 with hollow region；Described inserted sheet includes plug division 21
With locking plate 22, the insertion bore passages 13 of the matching of plug division 21 are simultaneously fixed wherein, to the locking plate of locking-type plug
22 extend hollow region 11 to be formed locking with the interference of the step of plug through described fluting, will not fall off plug 50, institute
Form step in the main body for the plug stated, its similarly to the prior art, not reinflated description herein.Preferably, locking plate with it is described
The contact position of step of plug be located at plug corner, by the way of four point positioning.The section of plug is that corner is circular arc
Or straight line chamfering is square, meanwhile, described hollow region is also circular arc or straight line chamfering structure for corresponding corner, connects frame
Frame is square structure and middle part hollow region is the structure with circular arc chamfering or straight line chamfering, described locking plate and plug division structure
L-shaped harden structure, riser is as plug division, and transverse slat forms locking plate, then transverse slat can be formed with the step of plug after such insertion
Interference.
Described U-shaped inserted sheet includes two plug divisions of both sides and connects the linkage section 24 of two plug divisions, respectively certainly
Connection framework described in the insertion of both sides, i.e. two U-shaped inserted sheets can realize the genlocing of plug both sides, ensure plug connection status,
The U-shaped inserted sheet is two and uses both sides move mode, and reducing unblock needs the stroke that operates, is stuck in plug corner, four
Point location firm stable, stroke is approximately the 1/3 of unilateral mobile claw stroke, because the reduction of operational stroke avoids meeting and side
The equipment interference on side, the problems such as can not operating.
Certainly, for the utility model because U-shaped inserted sheet also can using one side insert by the way of, such as outside compared with
Unilateral insertion is set at large space, and the smart that more can further lift product design is engaged with both sides insertion.
Wherein, to prevent locking plate and step from departing from locked state, described bore passages the inner is formed with plug division end
There is retaining mechanism, specifically, described retaining mechanism includes forming the latch hook in plug division inner end, and is matchingly arranged on
Described bore passages are inner and corresponding with described latch hook spacing preiection, and described spacing preiection section is triangular in shape or ball
Shape, i.e. both sides are inclined-plane or arc surface, and as one of embodiment, the projected direction of described latch hook is court
To described hollow region side, the vibration for so extracting either direction of insertion does not interfere with locking effect or described latch hook
Projected direction for plug extract direction side, by with the prestressed compression of plug, ensure not falling out, only downwards compress insert
Seat could be extracted, and further lift locking effect.
Second specific embodiment
This specific embodiment is identical with the first specific embodiment agent structure, equally includes connection framework and U-shaped inserted sheet,
On the basis of said structure feature, to improve the performance of grafting effect and product, the bore passages outside is formed with anticreep
Platform, described anticreep platform lateral surface is inclined-plane, and medial surface is facade, and described latch hook leading flank is that inclined-plane trailing flank is facade,
It using inner chamber feeder connection side is outer that described inner side and outer side, which is, and bore passages end or center illustrate for inner side.
Anticreep platform is set, and when inserted sheet inserts connection framework, outer inclined-plane, which is oriented to, causes latch hook deformation to lead to insert inner chamber
Road, after insertion, two facades turn into opposite face, and inserted sheet is more displaced outwardly, will be tighter so that inserted sheet can not depart from.Inserted sheet
It by anticreep platform structure design, will not fall off, avoid inserted sheet and lose the problem of point.
3rd specific embodiment
This specific embodiment is identical with the first or second specific embodiment agent structure, same comprising connection framework and U-shaped
Inserted sheet, on the basis of said structure feature, to improve the performance of grafting effect and product, the described connection of U-shaped inserted sheet
Section inside middle portion is formed with notch 23, while described two plug divisions are collapsed inwardly, in Figure of eight structure because plug division
The latch hook of end is present, and only having end in insertion process has friction, and the internal face with bore passages is reduced at other positions of shank
Friction, inserted sheet is operated smooth degree raising in module, reduce friction.
Further, part of the described bore passages 13 on the outside of spacing preiection is to be incrementally increased in locking plate thickness direction
Horn mouth to insert plug division, the height of the partial lumen passage on the inside of spacing preiection matches with plug division.With limit
Position projection is turning point, and the guide space when lock plug operates before spacing preiection is arrived at is very big, by guide space progressively
Reduce, in previous paragraphs internal friction very little, the effect of spacing preiection and latch hook forms a feedback, after the point is crossed, friction
Power increases, and after the connection side of connection framework is inserted correspondingly into the notch of inserted sheet, plug division likewise enters locked position, carries simultaneously
For feel and visual duplex feedback, the interaction of user and product is improved, strengthens use feeling.
4th specific embodiment
Present embodiment discloses it is a kind of can locking-type plug distribution socket, including shell is multiple to be fixed on such as PDU shells
The unit socket module 30 of PDU housing face-plates 40, and inserted with what the described one-to-one corresponding of unit socket module 30 was fixedly connected
Head anticreep self-locking mechanism, further, the bottom surface surrounding of connection framework 1 is provided with four grabs 14, plate above described shell
On formed with the mouth that allows corresponding with described grab.The edge of unit socket module 30 is blocked by grab 14 first, forms card
The formula of holding is fixed, and then the connection grab 31 of range site jack module 30 is fixedly connected with shell, while allows mouth on top panel
The lateral surface of hook can be formed hold it is spacing, this hook in jack module, preventing plug from dropping especially of the present utility model from
Latch mechanism fastening can be stuck on panel after being assembled on panel, will not fall off.That is, connection framework 10, unit socket mould are completed
The fixation of block 30 and PDU shells top panel 40, the structure realize inserted sheet 2 and are assembled into product, have saved space, effective to improve
The quantity of socket on every PDU product.Preventing plug from dropping self-locking mechanism is absolute construction, is applicable to any standard socket
On, there is great versatility.Wherein, the connection of connection framework and unit socket module can also use other types, such as weld
Or clamping of other forms etc..
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
