Embodiment
The utility model is described in detail below in conjunction with embodiment.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 1, an embodiment of the ground connection frock that the utility model provides, mainly contains three-decker, comprises metallic conductor 100, insulating case 200 and a magnet 300.
See Fig. 1 and Fig. 2, metallic conductor 100 is positioned at the intermediate layer of whole frock, makes primarily of metal material, and its electric conductivity is good, for by needing the sheet metal component of ground connection to be communicated with electrical control cubicles ground wire, is grounded.Preferably, the material of metallic conductor 100 is copper.Particularly, see Fig. 3 and Fig. 4, one end of metallic conductor 100 is metal link 110, is used for contacting with sheet metal component.The other end is earth terminal 120, and earth terminal 120 connects electrical control cubicles ground wire by wire.During commodity inspection test, the metal link 110 of metallic conductor 100 being contacted with needing the sheet metal component of ground connection, being equivalent to sheet metal component and being communicated with electrical control cubicles ground wire by metallic conductor 100, can effective grounding be realized.
See Fig. 1 and Fig. 2, insulating case 200 is positioned at the outermost layer of whole frock, makes primarily of insulating material, plays protective action.In the present embodiment, insulating case 200 and metallic conductor 100 interference fit, be socketed in the outside of metallic conductor 100, make whole frock outermost layer non-conductive, the potential safety hazard such as electric leakage when eliminating operation.Preferably, insulating case 200 is antistatic POM rod (Polyoxymethylene, polyformaldehyde crystal), and see Fig. 5 and Fig. 6, resistance to wear is good, and feel is better, and convenient operation personnel grip.
See Fig. 1 and Fig. 2, magnet 300 is positioned at the innermost layer of whole frock, is mainly used in the fixing of whole frock.In the present embodiment, magnet 300 and metallic conductor 100 interference fit, be socketed in the inside of metal link 110.The outer face of magnet 300 is lower than the end face of metal link 110, namely the end face of metal link 110 protrudes relative to the outer face of magnet 300, so, position is not sprayed (such as near product at magnet 300, on valve rack) time, under the effect of magnetic force, the metal link 110 of metallic conductor 100 just can effectively contact with sheet metal component, earth terminal 120 is communicated with electrical control cubicles ground wire by wire, thus realizes complete machine effective grounding.Magnet 300 can be nickel plating magnet, and magnetic is strong, and absorption is stable.
The ground connection frock that the present embodiment provides, can be used for the commodity inspection test of various sheet metal component.During test, this ground connection frock only need be placed on not spraying position (such as, on valve rack) and can completing fixing of product by operating personnel, pulls out, easy accessibility, very convenient operation, greatly improve production efficiency after testing.
As a kind of embodiment, see Fig. 2, the end face of insulating case 200 near metal link 110 one end is lower than the end face of metal link 110.For preventing operator from getting an electric shock, the length of insulating case 200 can be equal to or greater than the length of metallic conductor 100.If the end face of insulating case 200 near metal link 110 one end protrudes the end face (namely higher than the end face lower than metal link 110) of the metal link 110 of metallic conductor 100, then can form obstacle to metal link 110 with effective contact of sheet metal component, be unfavorable for the realization of ground connection.So in the present embodiment, arrange the end face of the end face of insulating case 200 near metal link 110 one end lower than metal link 110, like this, insulating case 200 would not form obstacle to metal link 110 with effective contact of sheet metal component.
Further, the end face of insulating case 200 near metal link 110 one end is lower than the end face 1-2 millimeter of metal link 110, it can be 1 millimeter, 1.5 millimeters, 1.8 millimeters or 2 millimeters, to prevent due to insulating case 200 and metallic conductor 100, to be socketed length too little, and metallic conductor 100 is come off.Preferably, the end face of insulating case 200 near metal link 110 one end is lower than the end face 1 millimeter of metal link 110, and namely the end face of metal link 110 protrudes the end face 1 millimeter of insulating case 200 near this metal link 110 one end, stabilized structure.
In like manner, as a kind of embodiment, the outer face of magnet 300 is lower than the end face 0.2-0.3 millimeter of metal link 110, it can be 0.2 millimeter, 0.21 millimeter, 0.25 millimeter or 0.3 millimeter, to prevent due to magnet 300 and metallic conductor 100, to be socketed length too little, and magnet 300 is come off.Preferably, the outer face of magnet 300 is lower than the end face 0.25 millimeter of metal link 110, and namely the end face of metal link 110 protrudes the end face 1 millimeter of insulating case 200 near this metal link 110 one end, stabilized structure.
See Fig. 1, as a kind of embodiment, ground connection frock of the present utility model also comprises holding screw 400, is fixedly connected with between metallic conductor 100 with insulating case 200 by holding screw 400.Metallic conductor 100 and insulating case 200 on the basis of interference fit, then by holding screw 400 stationary positioned, make the structure of whole frock more firm.
The ground connection frock that the utility model provides can be designed to flat, the various difformity such as coniform according to the structure of carrying out the product of commodity inspection test of reality.As shown in Figure 1, metallic conductor 100 can be open column shape, and accordingly, magnet 300 is in column.This entirety is that the structure scope of application of column is comparatively wide, and be specially adapted to the non-spray metal such as valve rack, electrical appliance kit part, because its contact area is little, structure is simple, easy to operate, can carry out effective grounding fast.
Above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
