Abstract

The utility model discloses an expansion board capable of being stably fixed. The expansion board comprises an expansion board main body and a buckling part, wherein the expansion board main body protrudes and extends out of the bottom edge to form a plug-in connection board; the buckling part comprises a connecting plate and a hooking part; the hooking part extends downwardly from the bottom surface of the connecting plate; one side edge of the connecting plate is fixed on the expansion board main body; and the hooking part corresponds to the plug-in connection plate of the expansion board main board with an interval. Accordingly, when the expansion board provided by the utility model is inserted into a plug-in connection seat with an oblique angle block formed on one side wall, the hooking part of the buckling part can be correspondingly clamped and buckled with the oblique angle block, so that the plug-in connection board can be stably inserted into the plug-in connection seat, and is difficult to separate from the plug-in connection seat when shock or vibration brought by external force exist.

Description

But the expansion board of secure

Technical field

The utility model is about a kind of expansion board, but refers to a kind of expansion board of secure especially, can strengthen the steadiness that expansion board is solidly plugged in the motherboard plug socket, makes its disengaging plug socket that is difficult for being impacted.

Background technology

Expansion board is a considerable ring in the computing machine Related product, and its effect mainly is the function that expands computing machine, illustrates, and the USB expansion board is in order to provide computer access USB the function of device; The video signal expansion board is then in order to provide computing machine that image source is exported, with the display device show image of outside; And existing expansion board such as Fig. 7 and shown in Figure 8 include:

One expansion board body 70, its base projection is formed with a plugboard 71, and is formed with one group of conductive junction point 711 on this plugboard 71.

Above-mentioned expansion board is inserted in the plug socket 91 of an external host plate 90 with wringing fit; Be formed with in this plug socket 91 with this plugboard 71 on the corresponding electrical contact of this group conductive junction point 711; And these plug socket 91 outside wall surface are formed with one group of oblique angle piece 92, and when this plugboard 71 inserted in this plug socket 91, this group conductive junction point 711 promptly formed contact with these plug socket 91 interior electrical contacts and is connected; Above-mentioned expansion board and motherboard 90 are formed to be electrically connected; And because these plugboard 71 wringing fits are inserted in the plug socket 91 of motherboard 90, be subject to vibrations come off, so can further one fixed dam 80 be set in this expansion board body 70 side vertical with its base; This fixed dam 80 supplies a screw 81 to pass and is fixed at host housing, with further fixing this expansion board body 70.

Yet with the fixed dam 80 of screw 81 locking in being given a shock or external force such as bump and when being out of shape, can form as shown in Figure 9, with plugboard 71 oblique this plug sockets 91 of extracting of this expansion board body 70; Making expansion board and motherboard 90 form is electrically insulated; Make this motherboard 90 can't see through this group conductive junction point 711 transmission data, cause expansion board to operate, therefore; This kind expansion board is unsatisfactory, needs further improvement.

Summary of the invention

Because the fixing unsteady technological deficiency of above-mentioned existing expansion board, the fundamental purpose of the utility model is to propose the plug socket that a kind of cooperation has the oblique angle piece, with the expansion board of secure on plug socket.

But desiring to reach the employed major technique means of above-mentioned purpose is to make the expansion board of this secure include:

One expansion board body, its base projection is formed with a plugboard, and is formed with one group of conductive junction point on this plugboard;

One fastener comprises an a plate and a hook part; Wherein to extending below, and this web joint one side is fixed on this expansion board body from the web joint bottom surface in this hook part, makes this hook part at interval to plugboard that should the expansion board body.

The utility model expansion board is because of having this fastener, thus in this plugboard inserts this plug socket the time, the hook part of this fastener then correspondence and this plug socket outside wall surface the oblique angle piece mutually trip fix, make the plugboard secure in plug socket; In addition, also be convenient to pull away use,, can the utility model expansion board be extracted in plug socket as long as remove the trip state of this fastener hook part and plug socket oblique angle piece.

Embodiment

See also figure to 1 and Fig. 2, but the expansion board of the utility model secure includes:

One expansion board body 10, its base projection is formed with a plugboard 11, and is formed with one group of conductive junction point 111 on this plugboard;

One fastener 20 comprises an a plate 21 and a hook part 22; Wherein this hook part 22 from these web joint 21 bottom surfaces to extending below; And these web joint 21 1 sides are fixed on this expansion board body 10; Make this hook part 22 at interval to plugboard 11 that should expansion board body 10; In present embodiment, this web joint 21 is fixed on the end face of expansion board body 10 1 sides and is formed with

plural screw

211, and 10 pairs of expansion board bodies should also be formed with plurality of through holes 101 in plural screw 211 positions; So can cooperate plural screw 212 to pass on it and be screwed into again in the screw 211 of web joint 21 after perforation 101, this fastener 20 screwed togather be fixed on the expansion board body 10; Again; This hook part 22 includes plural connecting link 221 and and laterally colludes bar 222; These plural number connecting link 221 parallel ends arranged side by side and common from 21 bottom surfaces to extending below; This laterally colludes the then common common other end that connects this plural number connecting link 221 of bar 222, and this laterally colludes bar 222 and is formed with hook part 2221 on again towards plugboard 11 1 sides again.

Above-mentioned expansion board body 10 further includes again:

One fixed dam 30 is arranged at a wherein side vertical with its base in the expansion board body 10;
