Description

The fixed structure of edge card

Technical field

The utility model relates to a kind of fixed structure of edge card more particularly to a kind of fixed frame inward flange card is pressed to Bottom dead centre more makes the contact and electric connector of edge card so that edge card bottom both ends are held in two follow blocks of fixed frame really Termination contact it is good and without any crooked situation, it is ensured that edge card operates stabilization in high-frequency signal.

Background technique

Modern computer science and technology is with fast development of making rapid progress, and desk-top or laptop has been prevalent in society Each corner, the development trend of computer is also strong towards calculation function, speed is fast and direction small in size strides forward, and makes computer-internal Connector also significantly reduce therewith, to be suitable for the development trend of modern computer, furthermore, in order to coupled computer operation Function is constantly promoted, is progressive, and the mainboard of computer must expand memory card, adapter or functional cards etc., will be whole Application function, operational efficiency and operational capacity upgrading, however, in order to expand memory card, adapter or functional cards on mainboard Deng opposite connector to be also arranged on mainboard to supply the electrical grafting such as various memory card, adapter or functional cards, whereby It is used as transmission electronic signal.

However, locker can be all provided on the connector of mainboard at present, when expansion memory card, adapter or feature board Card docking can be fixed after on connector by locker, still, due to industrial computer, car-mounted computer Or the computer of other patterns, vibration situation can be generated at runtime, so locker is easy to happen the case where loosening, so that It loosens, tripping or emerge in except locker in memory card, adapter or functional cards etc. are easy, lead to not and connector Form good electrically conduct.

General bayonet connector (Edge Card Connector) need to reduce height to meet technologic limit for height, also The requirement of minimum usable floor area need to be met, therefore propose the design scheme of bulk-breaking formula, scheme is that connector (Connector) can be first Carry out surface mounting technology (SMT) technique, subsequent edge card (Edge Card) the fixed frame insertion connection for again preparing group Device.Therefore edge card is first fixed on two end device of a bottom side and has the fixed frame of two screw holes by some dealers, and makes to connect below edge card Point exposes to fixed frame, then after edge card is inserted in the bayonet connector on a circuit board, then fixed frame is utilized screwed lock Together in screw hole and circuit board, to complete for edge card to be fixed on the fixed structure of bayonet connector, but these operators are applied The shortcomings that formula, is that edge card assembly crewman must hold closure tool (screwdriver) and assemble, aobvious with artificial sealed assembling Very time-consuming inefficiency, and needing to be engaged in this journey dealer is improved assembling flow path.

Therefore, how to try to solve the missing of the above-mentioned prior art and inconvenient, as related dealer, which wants to study, to be changed Where kind direction.

Utility model content

Therefore inventor collects related data in view of above-mentioned problem and missing, by being evaluated and considered in many ways, and with Many years of experience accumulated in this industry designs the fixed structure of such edge card by constantly trying and modifying.

The main purpose of the utility model is that fixed frame is provided with two adjustment elastic slices above frame body, it is symmetrically disposed on frame Above body, and with more an adjustment gap between the two adjustment elastic slice and the frame body, the adjustment gap is to provide two adjustment The elastic space that elastic slice pushes, presses to bottom dead centre for fixed frame inward flange card, so that edge card bottom both ends are held in really Two follow blocks of fixed frame, the termination contact of the contact and electric connector that more make edge card is well and without any crooked situation, it is ensured that Edge card operates stabilization in high-frequency signal.

The secondary objective of the utility model is for edge card to be first placed in a fixed frame, then the fixed frame is inserted in In one electric connector, in assembling flow path, the fixation of edge card and fixed frame is without the use of any hand-held tool, it is only necessary to by edge card It is sticked in fixed frame, then fixed frame is inserted in electric connector also without the use of hand-held tool, it is only necessary to utilize fixed frame The clip elastic slice of two sides is sticked in two support arms of electric connector to complete to fix, and is shaken during manufacture or transport Dynamic or vibration will not generate the case where fixed frame is separated with electric connector, by the snap-in structure of fixed frame and electric connector, To realize the purpose that edge card is fixed on to electrical connection device without tool.

To achieve the above object, the utility model provides a kind of fixed structure of edge card, and an edge card is first placed in one In fixed frame, then the fixed frame is inserted in an electric connector, which includes:

One frame body, one side have an accommodation groove, which provides the edge card and accommodated；

Two stop catch plates are set to the two sides of the accommodation groove, for supporting a surface of the edge card；

Two limited blocks are set to the two sides of the accommodation groove, for supporting another surface of the edge card, two limited block with Institute's forming region clamps the two sides of the edge card between two stop catch plate；

Two follow blocks are set to the two sides of the accommodation groove, to support the both ends of the edge card bottom；And

An at least adjustment part is set to above the frame body, by depress the adjustment part make at the top of the edge card by pressure to Lower section is mobile, so that the both ends of the edge card bottom are held in two follow block simultaneously.

Wherein the adjustment part is made of an adjustment elastic slice.

Wherein the preferred implementation structure of the adjustment part is two, is symmetrically disposed on above the frame body, and two adjustment part with With more an adjustment gap between the frame body, the adjustment gap is to provide the elastic space of two adjustment part pushing.

Wherein the electric connector further includes a pedestal, which is transversely provided with one entered for an edge card insertion at surface and inserts Slot, and terminal group side is equipped with and extends in the slot and form a docking part in electrical contact with the contact in the edge card, The weldering extended multiple weld pads outside the pedestal and on a corresponding circuit board and form connection is equipped in the another side of the terminal group again Socket part.

Wherein the electric connector has a pedestal, and a slot is equipped in the pedestal, is equipped with a terminal group, the end in the slot Subgroup provides the edge card and is planted, and is each provided with a support arm at the pedestal both ends, which respectively has an idle space, Two accommodating space provides two clip elastic slices and carries out engaging positioning.

The wherein two one clip elastic slice of each setting in outside of frame body, which includes a support division, a holding section and one The support division in release portion, the clip elastic slice is placed through in the accommodating space of the support arm, and the holding section supports card slot and gear Stop is to form location structure.
