Description

The interface card fixing structure

Technical field

The utility model is a kind of interface card fixing structure, especially a kind of interface card is fixedly maintained an interface card fixing structure that is parallel to the motherboard fixed position.

Background technology

Peripheral assembly links interface card connector (PCI card connector); the quick linkage interface card connector of peripheral assembly bayonet connectors such as (PCI express card connector) is a connector commonly used when being connected with master card as interface card; for the occupied space of the installation that reduces interface card; some PCIcard; interface card such as PCI express card are parallel with master card; and keep the mode of a fixed range to be fixed in master card with master card; usually apply to the interface card of this kind mode; except a side with bayonet connector with master card is connected; opposite side in interface card can be provided with fixing structure usually, to keep interface card and bayonet connector good contact effect.

Existing interface card fixing structure is the structure of a strip, be arranged at the end in addition of the relative bayonet connector of interface card, the two ends of this fixing structure are provided with fastener, interface card then is provided with shrinkage pool in the position of relative this fastener, make fixing structure interface card can be held in this fastener, then be connected with elastic component between fastener and the fixing structure base portion,, make fastener can discharge interface card in order to the resilient movement fastener.

Above-mentioned fixing structure can reach the immobile interface card really, the effect that keeps interface card and bayonet connector well to contact, but also on master card, occupied simultaneously bigger position, under compact designer trends, improved space has been arranged in fact at electronic product now.

U.S.'s patent of invention discloses No. 2005/0164540, then disclosed a kind of interface card fixing structure of separate type, interface card one side is fixed in this fixing structure separation, have a base portion, and up extend the supporting part of setting by base portion, one be located at supporting part on guide posts, extend elastic arm and the blocking arm that the foot section, that is provided with is located at the base portion both sides respectively by base portion below; The disclosed fixing structure of this patent is by being provided with by separating, reach and reduce the shared area of fixing structure, for easy to make and saving material cost, whole retaining piece is to be formed by sheet metal punching press bending, therefore guide posts also is the one-body molded base portion that is fixed in, after making that retaining piece is fixed in motherboard, the position of guide posts is also fixed, but the kenel kind of interface card is quite a lot of, it is also how much variant on specification that the interface card various brands of same kenel are manufactured, and therefore will make fixing structure can be applicable to interface card, need make the retaining piece of diverse location guide posts according to situation, quite inconvenient, also make product have stock's puzzlement.

The utility model content

Main purpose of the present utility model is to provide a kind of interface card fixing structure, for reducing the shared space of fixing structure, makes electronic building brick more convenient in space utilization, also can promote radiating effect simultaneously.

Another main purpose of the present utility model is to provide a kind of interface card fixing structure, to improve the utilizability of fixing structure, with the interface card of adaptive different size, and then reduces quantity in stock.

A purpose more of the present utility model is to provide a kind of interface card fixing structure, for strengthening the intensity of fixing structure, reduces because of operating the possibility that causes reduce useful life improperly.

A kind of interface card fixing structure of the utility model, formed by at least two retaining pieces, each retaining piece is combined by a pedestal and a reference column, wherein reference column is that combination protrudes on the pedestal, because reference column is not and the one-body molded making of pedestal, also can be by reference column by different kenels, control the position that reference column protrudes in pedestal, again or by control the size of reference column by the reference column of different kenels, make retaining piece go for the interface card of various different brands.

Above-mentioned retaining piece is to be fixed on the master card, be located at both sides respectively with bayonet connector, can firmly be fixed on the master card in order to make retaining piece, the pedestal both sides flap of retaining piece bends downwards, this flap also extends outstanding pin separately, by by this pin retaining piece being fixed on this master card.

Interface card with the in addition end of bayonet connector joint face, be provided with two shrinkage pools, but these two shrinkage pool clips are on the reference column of retaining piece, the while retaining piece is a flap horizontal-extending one elastic arm wherein, this elastic arm extends upward a push pedal is set, the suitable upside that props up the interface card edge of the lower edge of this push pedal, simultaneously because the elastic reaction of elastic arm, make push pedal remain on the interface card edge, make interface card not can because of improperly the operation or vibrations and break away from, in the time interface card will being pulled away, then with above-mentioned push pedal to extrapolation, make push pedal discharge interface card.

In order to make above-mentioned elastic arm when discharging interface card, can not cause elastic fatigue because the application of force is excessive, retaining piece is provided with the buckle arm at above-mentioned elastic arm, and be provided with the block arm to this push pedal direction extension at another flap that is not provided with elastic arm, above-mentioned buckle arm is can be along with the elastic arm elastic displacement, above-mentioned block arm then is used for this buckle arm of button card, and in order to the amplitude of restriction elastic arm displacement, reaching elastic arm can be because of the stressed continuous elastic distortion of this push pedal.

For understanding spirit of the present utility model and technical characterictic more, after being specified in for embodiment now.
