Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Connector error-proof structure of the present invention comprises connector 1, circuit board 2 and Anti-stopping fixture 3.
Fig. 1 to Fig. 3 shows connector 1 according to an embodiment of the invention, the 3rd side 13 and the 4th side 14 that it comprises bottom surface 10, lay respectively at the first side 11 of 11 relative both sides, bottom surface and the second side 12 and the first side 11 and the second side 12 are coupled together.The bottom surface 10 of connector is provided with spaced a plurality of slot 15, slot 15 is opened on bottom surface 10 and first side 11 of connector simultaneously, the opening of this slot 15 is L-shaped, comprises the bottom surface peristome 151 that is positioned at connector bottom surface 10 and the side opening oral area 152 that is positioned at the first side 11 of connector.In embodiment shown in the figure, the quantity of slot 15 is 5.This connector 1 also has a pair of positioning tab 16, and this pair of positioning tab 16 is separately positioned on the 3rd side 13 and the 4th side 14, and each positioning tab is provided with connecting through hole 161.
As shown in Figure 4, circuit board 2 is provided with and a plurality of slots 15 a plurality of inserted sheets 25 one to one.In figure, this inserted sheet 25 is arranged on the base 20 that is positioned at circuit board upper surface, in the place ahead of base 20, is provided with electronic devices and components 22.
Refer to Fig. 5 to Fig. 7.Anti-stopping fixture 3 comprises substrate 30 and is fixed on the many convex tendons 35 that equate on substrate 30, with the quantity of slot 15.On substrate 30, offer the groove 31 passing for a plurality of inserted sheets 25, many convex tendons 35 are arranged on a side of groove 31, near groove 31.The end face of substrate 30 is provided with and described a pair of positioning tab 16 a pair of positioning convex column 36 one to one, and the end face of each reference column 36 offers screwed hole 361.Substrate 30 is also provided with interference structure, and this interference structure is used for when connector 1 anti-plug and circuit board 2 produces interference contacts, so that the inserted sheet 25 of circuit board 2 cannot insert in the slot 15 of connector.This interference structure comprises by substrate 30 near the centre position of the side of convex tendon one side to the first interference part 33 of downward-extension and is arranged on substrate 30 bottom surfaces, the second T-shaped interference part 34 of cross section.The second interference part 34 comprises by substrate 30 away from the side of convex tendon one side near the position of end to the vertical piece 341 of downward-extension and the lateral piece 342 intersecting vertically with this vertical piece 341.
During installation, first connector 1 is stacked on Anti-stopping fixture 3, and connector 1 and Anti-stopping fixture 3 are removably linked together, as shown in Fig. 8 to Figure 10.Wherein, a pair of positioning tab 16 of connector 1 is pressed in respectively in a pair of positioning convex column 36 of Anti-stopping fixture, and pair of screws 4 is passed respectively the connecting through hole 161 on a pair of positioning tab, and is connected with the screwed hole 361 in a pair of positioning convex column respectively.Meanwhile, the many convex tendons 35 of Anti-stopping fixture 3 insert in a plurality of slots 15 of connector near a side of the first side 11 from connector bottom surface peristome 151 respectively correspondingly, thereby shelter from the side opening oral area 152 of slot opening, make the inserted sheet 25 on circuit board 2 to insert slot from the bottom surface peristome 151 of slot.Then, by connecting connector 1, be connected with circuit board 2 with Anti-stopping fixture 3, as shown in Figure 11 and Figure 12.Anti-stopping fixture 3 is stacked on circuit board 2, and a plurality of inserted sheets 25 pass the groove 31 of Anti-stopping fixture, and from the bottom surface peristome 151 of connector, inserts in a plurality of slots 15 of connectors respectively correspondingly.Because the substrate 30 of Anti-stopping fixture is provided with interference structure, if position opposite, the first interference part 33 meetings and electronic devices and components 22 contacts, the second interference part 34 also can with base 20 contacts, and cause inserted sheet cannot insert the groove 31 of Anti-stopping fixture, therefore, thoroughly stop connector reversion and inserted circuit board.
The description of the present embodiment combines specific embodiment, but it should be understood by one skilled in the art that the present invention is not limited to embodiment described here, and can carry out various modifications and variations and do not deviate from the spirit and scope of the present invention.
