Description

Bayonet unit

[technical field]

The utility model relates to a kind of bayonet unit.

[background technique]

Adapter is the bridge that computer motherboard and interface 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 bayonet unit in addition on the host board, to avoid adapter because of external force collision or rock and promptly take place easily and the getting loose of connector, but the bayonet unit of finding design at present as shown in Figure 1, it comprises main part 1 and can make adapter be fastened at least one clamping part 2 on the main part 1, these clamping part 2 one sides are provided with can be guided adapter and be fastened on guide posts 20 on this clamping part 2, yet, this structure needs earlier clamping part to be mounted to main part when mounted, connect adapter again, more complicated so just is installed, is unfavorable for increasing work efficiency.

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

[model utility content]

The purpose of this utility model is to provide a kind of bayonet unit, and it installs simple, can effectively increase work efficiency.

To achieve these goals, the utility model bayonet unit comprises main part and can make first element be fastened at least one clamping part on the main part that described clamping part one side is provided with when first element is installed and makes clamping part be pressed into the projection of main part together.

Compared with prior art, the utility model bayonet unit, it installs simple, can effectively increase work efficiency.

[embodiment]

Below in conjunction with accompanying drawing the utility model electric coupler is described further.

See also Fig. 2 to shown in Figure 5, the utility model bayonet unit is used to fasten first element and (is adapter 10 in the present embodiment, certainly, also can be other abutment element, as circuit board etc.), it also is fixed on second element (being circuit board 20 in the present embodiment), uses with being installed on the electric coupler 30 that circuit pulls on 20, first end 11 of adapter 10 is connected with electric coupler 30, and bayonet unit is sticked on the adapter 10 and first end, 11 second opposed end 12.

Described bayonet unit comprises microscler base portion 110, be extended with two main parts 120 and two latches 130 that match with this main part 120 (also can at one end extend a main part certainly by these base portion 110 two ends one, at this moment corresponding also only be provided with a latch), described base portion 110, two main parts 120 and two latches 130 are to be formed by the insulating material integrated punching.The groove 122 that described each main part 120 offers a penetration hole 121 and is communicated with this penetration hole 121, extension and be equipped with a supported terminal part 123 in this groove 122.See also Fig. 4, in described penetration hole 121, also convex with an oblique overhead kick 124.Described latch 130 is extended to both sides by the penetration hole 121 of described main part 120 and forms, and described latch 130 is in order to engaging circuit board 20.

Described bayonet unit 100 also comprises and matches with described main part 120 and be placed in two clamping parts 140 in the penetration hole 121 of main part 120 (when aforementioned body portion only is provided with one, this clamping part also only is provided with one), this clamping part 140 can make described adapter 10 be fastened on the described main part 120.This clamping part 140 comprises and linking together and the parallel first post portion 141 and the second post portion 142, the wherein height of the aspect ratio second post portion 142 of the first post portion 141.End bending by the described first post portion 141 is provided with a hook part 143, this hook part 143 can be fastened on the adapter 10, make clamping part 140 be pressed into the projection 147 of main part 120 together when adapter 10 is installed being provided with one below the described hook part 143, described protruding 147 are extend horizontally away by described clamping part 140 one.See also shown in Figure 4, outwards convex with the anti-oblique overhead kick 144 that matches with described oblique overhead kick 124 in the described first post portion 141, when described clamping part 140 and main part 120 are done trace and are moved up and down, described oblique overhead kick 124 makes described clamping part 140 be not easy to break away from from described main part 120 in anti-oblique overhead kick 144 meeting overlapping driving fits.A plat part 145 extends to substantially horizontal in the described second post portion 142, described protruding 147 with described plat part 145 on same horizontal line, the end of this plat part 145 is extended a bump 146 downwards, this plat part 145 can be placed in the groove 122 of described main part 120, so that described clamping part 140 is fixed in the described main part 120, and described bump 146 can be resisted against 123 sides, supported terminal part of described main part 120, to prevent described relatively main part 120 move left and right of described clamping part 140.By described plat part 145 upwards one extend a guide posts 150, this guide posts 150 be bent to form by described clamping part 140 and its height identical with the thickness of adapter 10, and this guide posts 150 can suitably be pulled to described first cylinder, 141 directions.By these guide posts 150 guidings, adapter 10 can be fastened on the hook part 143 of described clamping part 140 more easily.

During assembling, at first the utility model bayonet unit is installed on the circuit board 20, adapter 10 again is fixed.Earlier electric coupler 30 is weldingly fixed on first end 21 of circuit board 20, then with the latch 130 of bayonet unit by in the hole 23 that is pressed in circuit board 20, clamping part 140 is placed on the penetration hole 121 of described main part 120, do not need to insert, first end 11 with adapter 10 inserts in the electric coupler 30 again, edge with the hole on the adapter 10 13 is relative with guide posts 150 again, then, firmly with second end 12 of adapter 10 to pressing down, along guide posts 150, the hole 13 of adapter 10 can be fastened on the hook part 143 of clamping part 140, at this moment, described adapter 10 can be pressed on simultaneously described protruding 147 with described plat part 145 on, can together described clamping part 140 be pressed in the penetration hole 121 of main part 120, like this, just do not need to install earlier clamping part 140 in the penetration hole 121 of main part 120, can effectively increase work efficiency.If will take out adapter 10, only need firmly guide posts 150 to be pulled to hook part 143 directions, adapter 10 can eject.
