[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model bayonet connector is described further.

To shown in Figure 5, the utility model bayonet connector includes an insulating body 2, conducting terminal 4, anti-misoperation device 6 and is arranged on the holding unit 1 of insulating body 2 one ends as Fig. 1.

It is microscler that insulating body 2 slightly is, the centre position is provided with a slot 20 of accommodating PCI-EXPRESS card 3, slot 20 both sides are provided with some terminal accommodation holes 21 of accommodating terminal 4, this slot 20 forms with this accepting hole 21 and is communicated with, these insulating body 2 outsides are provided with some protuberances 24 on one side, be provided with guide channel 25 between adjacent two protuberances 24, be provided with conducting terminal 4 in the terminal accommodation holes 21.The two side of insulating body 2 one ends is provided with two pivoted holes 22, and is provided with a spacing hole 23 away from the end on a sidewall.

Holding unit 1 includes a block-shaped main body portion 10, the pulling part 15 that extends back by main part 10, by main part 10 1 side one extend withhold arm 12, eject arm 13, pivot 11 and projection 14, and withhold arm 12 and further include a guide ramp 120.This pivot 11 can insert the pivoted hole 22 from insulating body 2 one sides, thereby this holding unit 1 is articulated on the insulating body 2.

Anti-misoperation device 6 comprises a main body 60, anti-misoperation device 6 can be fixed on the sidewall 62 that fixed structure on the insulating body 2 and an autonomous agent 60 extend vertically downward.Fixed structure comprises the tongue piece 61 that an autonomous agent 60 extends downwards, can insert in the slot 20, realizes the effect of location.Fixed structure also includes holding section 620 that holds mutually with insulating body 2 protuberances 24 and the guiding block 621 that matches with insulating body 2 guide channels 25, and holding section 620 and guiding block 621 lay respectively at the inboard of sidewall.During installation, holding section 620 and guiding block 621 can match with insulating body 2 protuberances 24 and guide channel 25 respectively, and tongue piece 61 is contained in the slot 20, and sidewall 62 is positioned at insulating body 2 outsides.In addition, also be provided with on the anti-misoperation device 6 and can guarantee that anti-misoperation device 6 inserts the structure of tram in the insulating body 2 (be the end wall 63 that at one end is provided with greater than guide channel 25 sizes in the present embodiment, but persons skilled in the art being expected other structure easily thus).

PCI-EXPRESS card 3 by holding unit 1 can be firm be connected on this bayonet connector, and because the setting of anti-misoperation device 6, the expansion board specification that can connect according to need be arranged on the suitable position of insulating body.Guaranteeing not can wrong plug PCI-EXPRESS card 3, has improved operating efficiency, and can realize required electric connection.

Certainly, anti-misoperation device 6 is fixed on the insulating body 2 can be in several ways, and as a location-plate (not shown) that is positioned at sidewall 62 opposite sides can be set, it can be fixed in anti-misoperation device 6 on the insulating body 2 jointly with holding section 620.Also can extend downwards by anti-misoperation device 6 main bodys 60 tongue piece 61 ' (as Fig. 6) that can insert in the slot 20 is set, this tongue piece 61 ' cooperates with terminal 4 and fixes anti-misoperation device 6.

Holding unit is embodied as also that other is multiple multi-form, as Fig. 7, shown in Figure 8, but its holding unit 5 independent stationary on circuit board, it comprises connecting portion 51 and buckling parts 52.

This connecting portion 51 is used for holding unit 5 is fixed in circuit board, be in the present embodiment a pair of with can with the harpoon of buckling parts 52 secure fit, certainly also can be other structures such as fixed leg that are wholely set with buckling parts 52.

This buckling parts 52 is used for the fixing expansion board, comprises main body 520 and by main body 520 outside upwardly extending first arm 521 and second arms 522, forms conduit between this first arm 521 and second arm 522, inserts for PCI-EXPRESS card 3.These first arm, 521 inboards are provided with stop block (not shown) in the position of adjacent end, only can blocking, PCI-EXPRESS card 3 makes progress to prevent PCI-EXPRESS card 3.Extension is provided with pulling part 54 and linkage part 55 to the end of this first arm 521 to both sides respectively, and wherein, linkage part 55 is roughly L-shaped, and its end is provided with an inside projection 550.Second arm, 522 ends are provided with position limiting structure 523, and this position limiting structure 523 is to be made of first projection, 524 and second projection 525 that is positioned at projection 550 both sides, moves within the specific limits with restriction projection 550, prevents that first arm 521 from fractureing because of excessively pulling.

Compared with prior art, because of the utility model bayonet connector does not need the various bayonet connector of otherwise designed (long or short), make simply, cost is also relatively low, and connects also comparatively stable, the anti-misoperation device of She Zhiing simultaneously, the expansion board specification that can connect according to need be arranged on the suitable position of insulating body, and can guarantee not can the wrong plug expansion board, improved operating efficiency, and be connected when cooperating stable correct with expansion board.

Certainly, described anti-misoperation device not only is confined to this, and also other unit of plastic is sticking thereon, or special mark is set thereon, all should drop in this protection range.
