Abstract

The utility model relates to the technical field of the computer connector, in particular to the structure of an adapting card expansion slot seat with convenient inserting and fetching and small spacing usage of the computer. A slot for the adapting card is arranged on the slot seat of the utility model and one end of the slot seat is provided with a supporting seat whose bottom is provided with a sliding rail. A slide block with a compression spring is matched with the supporting seat and a convex compression tongue with an inclined plane is arranged at the right front of the slide block. When the adapting card is perpendicularly inserted in the slot, the adapting card contacts with the inclined plane of the compression tongue to make the slide block with the compression spring slip back along the sliding rail under a horizontal force. When the adapting card is inserted, because of the restoring force of the spring, the slide block returns to the initial position to make the adapting card buckle the compression tongue so as to tightly fix the adapting card in the slot. As no other load materials are arranged on the side face of the expansion slot seat, the space of the computer mainboard is saved.

The improvement of adapter extended slot seat structure

Technical field:

The utility model relates to computer plug connector technical field, refers in particular to a kind of extended slot seat structure fixing and that take off adapter of can pegging graft quickly and easily.

Background technology:

Adapter and extended slot seat are two discrete parts, and they need be combined during the grafting adapter just to reach the function of the adapter that is fastened.Extended slot seat shown in the accompanying drawing 1 is preferable a kind of of present result of use, and it is that a portable plate 02 and a fixed head 03 are set on a side end face of groove seat main body 01, and the front end of portable plate 02 and fixed head 03 also outwards is convexly equipped with two respectively and

grips plate

04 and 05; The front end of portable plate 02 is the holding section 021 of one " U " shape, the top of this holding section 021 inner face is convexly equipped with a dop 022, be positioned at and offer the breach 031 of dodging on the fixed head 03 on portable plate 02 opposite, hold when gripping

plate

04 and 05 when pinching, portable plate 02 rotates around its root, the constraint that dop 022 is removed adapter 06, thereby adapter 06 can be taken off from groove seat main body 01, in like manner, desire only need be pinched to hold and

grips plate

04 and 05 with in the adapter 06 insertion groove seat main body 01 time, make dop 022 partially in a side, after adapter 06 inserts, unclamp portable plate 02, dop 022 is pressed onto on the adapter 06 can be fixed on adapter 06 on the groove seat main body 01.It is comparatively convenient that the connector of this structure uses, but also exist following weak point: at first, owing to portable plate 02, fixed head 03 add that

gripping plate

04 and 05 needs long length, thereby the overall dimension of groove seat is long, has increased usage space greatly; Secondly, because portable plate 02 is to realize resilience by self elasticity, thereby fasten adapter 06, but the elasticity of plastics and not really desirable, after using a period of time, portable plate 02 will follow the string gradually, thereby be difficult to fasten adapter 06.

At the weak point on the existing groove holder structure, I have announced that " a kind of improvement of adapter extended slot seat structure " (China Patent No. is: 03224567.X), it is that a side at groove seat main body one end end face is provided with supporting base, have a vertical through holes on the supporting base, this vertical through holes cooperates with a rotational pin, the upper end of rotational pin is respectively equipped with a handle and a horizontal press strip, when pulling handle makes rotational pin when the axis line of through hole rotates, press strip can be pushed down or the adapter of relieving and the grafting of groove seat main body.

A kind of improvement as above-mentioned technology, also be provided with barricade on the groove seat main body end face on supporting base opposite, have on the end face of this barricade and dodge breach, the front side of dodging the breach upper surface forms and prevents that press strip is from dodging the salient point that withdraws from the breach, the rear side of dodging the breach upper surface is formed with pressure surface, when press strip was pressed together on the adapter, this pressure surface can be pushed down press strip, pushed down the intensity of adapter to increase press strip.

When above-mentioned technology is further improved again, through hole is a up-small and down-big shoulder hole, the rotational pin shank middle part that cooperates with this through hole then forms bulge loop, the diameter of bulge loop is greater than the internal diameter of stepped through hole upper end, but internal diameter less than stepped through hole lower end, the middle and lower part of shank is divided into two parts by a vertical groove that runs through its periphery both sides, after these two parts close up, shank can put in through hole, and after these two parts open, shank is tipped upside down in the through hole, thereby makes that shank is unlikely to withdraw from rotation process.

Another improvement as technique scheme, in the upper surface of supporting base, a side of through hole, be provided with a projection, this bumping surface forms stopper slot to a side of through hole, the shape of this stopper slot is asymmetric, high and its outside end face of its inner side end, stopper slot matches with the guide vane end stop that is convexly equipped with in the rotational pin upper end, is used for limiting when rotational pin is deactivated state its automatic revolution.

Though, adopt above-mentioned design to adopt multiple improvement project, can make the size of supporting base and barricade shorter, the total length of groove seat shortens dramatically, thereby has saved the space; In addition because the utility model adopts rotational pin to fasten adapter, uses more convenient, and also greatly raising of the degree of reliability that fastens.But it still needs manual engagement to finish the grafting of adapter and groove seat, takies certain operating time.
