Description

Device for fastening

[technical field]

The utility model relates to a kind of device for fastening.

[background technology]

Adapter is the bridge that computer motherboard and interfacing equipment are linked up, because portable electronic devices is constantly pursued the slimming on the volume, adapter also constantly develops towards miniaturization.

At present, be example with the adapter of the Mini PCI specification that is widely used in notebook, promptly adopt the transverse-plug type design, be smooth bottom surface after allowing adapter be plugged in connector, significantly to dwindle the height that takies in the machine plate.

Except adding the power of holding that raising connector itself provides; usually also provide adapter complementary buckling structure in addition on the machine plate; avoiding adapter because of external force collision or rock and promptly take place easily and the getting loose of connector, but present being seen design is generally the single type structure, yet; the structure of single type structure is all quite complicated; make difficulty, cost is higher, and also rather bothers in operation; buckle during its fixed adaptation card and hold insecurely, adapter easily comes off.

Therefore, be necessary to design a kind of novel buckling structure, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of new device for fastening, and it is simple in structure, and cost is lower, and easy to operate, and holding force is strong, and button is held firmly.

In order to reach above-mentioned creation purpose, device for fastening of the present utility model can be fixed on the circuit board, comprise that the metal that can insert cooperation mutually accepts body and insulator, wherein, metal is accepted body and is comprised that in order to the fixed sturcture of fixed insulation body and the Fixed Division that fixes with circuit board, insulator is provided with one at least can buckle the buckling structure of holding connected components.

Compared with prior art, device for fastening modern design of the present utility model, simple in structure, cost is lower, and easy to operate, can well detain to hold adapter and make it keep firm.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model device for fastening is described further.

Please be simultaneously referring to figs. 1 through shown in Figure 5, the utility model device for fastening can be fixed on the circuit board 5, be used for button and hold adapter 6 (certainly, also can be other to connected components, as circuit board etc.), be that bayonet connector 7 on being installed on circuit board 5 uses, an end of adapter 6 is connected with bayonet connector 7, and device for fastening is fixed in the other end of adapter 6 and fastens towards the other end extension of adapter 6 and with the described other end.

This device for fastening comprises that the metal that can insert cooperation mutually accepts body 1 and insulator 2.Wherein, described metal is accepted body 1 and is comprised body 14 and fixed sturcture, elasticity carrier 11, Fixed Division 12 and guide groove 13.Fixed sturcture is in order to fixed insulation body 2, comprise projecting upwards and bending and be parallel to the bottom and extend two limiting sections 101 be " " shape forward by body 14 inboards, this two limiting section 101 lays respectively at the two ends of body 14, and by the upwards vertical holding section 102 of extending in order to butt insulative body portion one side of body 14 middle inside, this holding section 102 is positioned at the centre of two limiting sections 101; 102 relative opposite sides extend upward and bend certain radian to holding section 102 directions two elasticity carriers 11 from the holding section by body 14, but the opposite side relative on the elasticity butt insulator 2 with teat; Fixed Division 12 is extended forward by the two ends of body 14, and rectangular schistose texture can be fixed on device for fastening on the circuit board 5 by modes such as welding; By body 14 and holding section 102, elasticity carrier 11 formed guide grooves 13, insulator 2 can laterally inserted guide groove 13 in.

Insulator 2 comprises base portion 20 and can buckle the buckling structure of holding connected components (be teat in the present embodiment, certainly, also can be other structure) that this teat 21 is located at the two ends of base portion 20 1 sides; One matches with above-mentioned limiting section 101 and is the lamellar extension 23 that is extended forward by base portion 20, and described extension 23 can be contained in the receiving space that limiting section 101 and body 14 form, in order to limit insulator 2 moving in vertical direction; And the two corresponding card divisions 22 of returning that are convexly equipped with forward by insulator 2 lower end extensions 23, above-mentioned holding section 102 can be contained in twice card division 22 formed receiving spaces, to limit insulator 2 moving in the horizontal direction.

When adapter 6 is installed, end with adapter 6 inserts in the bayonet connector 7 earlier, then, the other end that forces in adapter 6 is to pressing down, when reaching teat 21, teat 21 is because stressed meeting is mobile backward, thereby promoting elasticity carrier 11 also moves backward, when it surpasses teat 21, teat is got back to the starting position owing to can move forward by the elastic acting force of elasticity carrier 11, this moment, the other end of adapter 6 just was held in two teats 21 times, made adapter 6 firm being fixed on the circuit board 5.During buckling state, adapter 6 is basically parallel to circuit board 5.If will extract adapter 6, only need pull insulator 2, give elasticity carrier 11 1 acting force backward, teat moves backward, can discharge the adapter of holding 6 of detaining.

Certainly, buckling structure also can be provided with a rubber-like elastic arm 24 (certainly for: insulator in the above-described embodiments, also can be the elastic arm of other structure), teat 21 is positioned at the end of elastic arm, thereby can produce a certain amount of moving forward and backward, it also can reach the effect that button is held adapter, makes firm being fixed in (as shown in Figure 6) on the circuit board of adapter.

The buckling structure simplicity of design novelty of the utility model two-piece type, cost is lower, and easy to operate, can well detain to hold adapter and make it keep firm, easily comes off thereby overcome between adapter and the connector, and button is held unstable problem.

Certainly, persons skilled in the art are associated the fixed sturcture of other form easily according to foregoing, insulator is fixed on metal accepts on the body, also associate other buckling structure easily, detain to hold and fix connected components.
