Description
The utility model relates to a kind of anti-tampering earthing device, refers in particular to a kind of anti-tampering earthing device of connector.
The employed memory card of general digital camera or PDA, its structure is: installing one circuit board in a framework, at end installing a connector of this circuit board, install a metallic plate at the upper and lower of connector.
Yet this memory card is subjected to electromagnetic interference easily, makes it make the mistake when the access data or the data of transmission; In addition, the upper and lower of this memory card has metallic plate, and therefore, static can be sent to circuit board by metallic plate when fetching memory card, and this static can be punched the memory body that is contained on the circuit board, causes damage.
The utility model is designed a kind of anti-tampering earthing device of connector at above-mentioned defective.
Main purpose of the present utility model provides a kind of anti-tampering earthing device of connector, and it can prevent Electromagnetic Interference and eliminate static.
For achieving the above object, the utility model adopts following two kinds of technical schemes:
First kind of technical scheme is: the side at circuit board is equiped with a connector, this connector has plurality of slots, be fitted with a terminal in this each slot, the upper and lower of above-mentioned connector is equiped with a metallic plate, the described slot that is arranged in the outer side edges of connector is equiped with two relative up and down earth terminals, and there is one " Contraband " shape shell fragment at the place, middle part of this earth terminal; One end salient point is arranged on the described metallic plate, and this end salient point leans against on " Contraband " shape shell fragment of above-mentioned earth terminal.
Second kind of technical scheme is: the side at circuit board is equiped with a connector, this connector has plurality of slots, be fitted with a terminal in this each slot, the upper and lower of above-mentioned connector is equiped with another metallic plate, the described slot that is arranged in the outer side edges of connector is equiped with two relative up and down earth terminals, and there is one " Contraband " shape shell fragment at the place, middle part of this earth terminal; The side edge of installing above-mentioned earth terminal at described connector is provided with a catching groove, is equiped with one " Contraband " shape clip in this catching groove, and the upper and lower that is somebody's turn to do " Contraband " shape clip respectively has a projection, and this projection is pressed against on " Contraband " shape shell fragment of above-mentioned earth terminal; Above-mentioned " Contraband " shape clip also has a flexure strip, and this flexure strip leans on the bottom surface of described another sheet metal.
After adopting technique scheme, because the earth terminal of connector has " Contraband " shape shell fragment, it contacts with the end salient point of metallic plate, and the pin end of this earth terminal is connected on the circuit of circuit board, therefore electromagnetic wave that makes metallic plate and absorbed or static are sent to the dividing circuit of leading on the circuit board by earth terminal, thereby electromagnetic wave or static led by circuit remove, so just avoided Electromagnetic Interference to influence the storage of data and transmission and static and punched the phenomenon that is contained in the memory body on the circuit board.In addition, in second technical scheme, " Contraband " shape clip is installed in the catching groove of connector, and the projection that is somebody's turn to do " Contraband " shape clip contacts with " Contraband " shape shell fragment of earth terminal, thereby makes two earth terminals be connected by " Contraband " shape clip; In addition, the flexure strip of " Contraband " shape clip leans against the below of another sheet metal of salient point of the no end, therefore makes another sheet metal that is installed in the connector upper and lower be connected.This structure can reach above-mentioned equally to be led except that electromagnetic wave and static, influence data storage and transmission to avoid Electromagnetic Interference, and static is punched the purpose that is contained in the memory body on the circuit board.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the three-dimensional exploded view of the anti-tampering earthing device of connector of the present utility model;
Fig. 2 is the assembling view of the anti-tampering earthing device of connector of the present utility model;
Fig. 3 is the stereogram of second embodiment of the anti-tampering earthing device of connector of the present utility model;
Fig. 4 is the three-dimensional exploded view of second embodiment of the anti-tampering earthing device of connector of the present utility model;
Fig. 5 is the assembling view of second embodiment of the anti-tampering earthing device of connector of the present utility model.
At first, see also Fig. 1 and Fig. 2, the utility model is that the side at circuit board 1 is equiped with a connector 2, and this connector 2 has plurality of slots 21, is fitted with a terminal 3 in each slot 21, is equiped with a metallic plate 4 at the upper and lower of connector 2.The slot 21a that is arranged in the outer side edges of connector 2 is equiped with two relative up and down earth terminals 5, there is one " Contraband " shape shell fragment 51 at place, middle part at this earth terminal 5, metallic plate 4 is provided with an end salient point 41, this end salient point 41 leans against on " Contraband " shape shell fragment 51 of earth terminal 5, thereby metallic plate 4 is contacted with earth terminal 5.
According to above-mentioned structure, because the earth terminal 5 of connector 2 has " Contraband " shape shell fragment 51, it contacts with the end salient point 41 of metallic plate 4, and the pin end of this earth terminal 5 is connected on the circuit of circuit board 1, therefore make electromagnetic wave that metallic plate 4 absorbed or static be sent to the dividing circuit of leading on the circuit board 1 by earth terminal 5, thereby electromagnetic wave or static led by circuit remove, so just avoided Electromagnetic Interference to influence the storage of data and transmission and static and punched the phenomenon that is contained in the memory body on the circuit board 1.
See also Fig. 3, Fig. 4 and Fig. 5, the side edge of connector 2 installing earth terminals 5 is provided with a catching groove 22, be equiped with one " Contraband " shape clip 6 in this catching groove 22, respectively be provided with a projection 61 at the upper and lower of this " Contraband " shape clip 6, this projection 61 is pressed against on " Contraband " shape shell fragment 51 of earth terminal 5; In addition, should a flexure strip 62 be arranged " Contraband " shape clip 6, this flexure strip 62 leans on the bottom surface of another sheet metal 4a.
By above-mentioned structure, " Contraband " shape clip 6 is installed in the catching groove 22 of connector 2, and the projection 61 that is somebody's turn to do " Contraband " shape clip 6 contacts with " Contraband " shape shell fragment 51 of earth terminal 5, thereby makes two earth terminals 5 be connected by " Contraband " shape clip 6; In addition, the flexure strip 62 of " Contraband " shape clip 6 leans against the below of another sheet metal 4a of salient point of the no end 41, therefore makes another sheet metal 4a that is installed in connector 2 upper and lowers be connected.This structure can reach above-mentioned equally to be led except that electromagnetic wave and static, influence data storage and transmission to avoid Electromagnetic Interference, and static is punched the purpose that is contained in the memory body on the circuit board 1.
The above only is a best specific embodiment of the present utility model, actual being not limited thereto, and all have identical or the variation person of the principle of equal effects, is all the protection range of this patent.
