Referring again to shown in Figure 3, the present invention is in order further to simplify the structure of existing connector and the purpose of further miniaturization, the contact site of each line end terminal 1 of line-end connector 10 of the present invention is designed to a pair of folder type shell fragment 122 that certain narrow slit 1221 is arranged especially, there is certain outer subtended angle the upper end of its folder type shell fragment 122, the importing when cooperating with convenient matching used with it plate end terminal.Folder type shell fragment 122 makes the upper end of folder type shell fragment 122 and the bigger vertical range of upper end formation of lead clamp 111 for vertical bending of direction opposite with lead clamp 111.
Please refer to Figure 6 and Figure 7, folder type shell fragment 122 passes from the perforation 22 of plastic body 2, and the second surface 20 ' of arrival plastic body 2, second surface 20 ' at plastic body 2 is provided with several guide grooves 24, each guide groove is by the center of this folder type shell fragment 122 that exposes, and slightly be wider than this narrow slit 1221, and respectively extend a segment distance, make a side of the terminal connections of the line end dorsad end 11 of guide groove 24 have opening 25 to two ends.Be designed to a long straight flat aciculiform with the plate end termination contact district 41 of line-end connector 10 matching used plate terminal adapters 40 of the present invention, its head design has certain chamfering, its effect is the same with the outer subtended angle of folder type shell fragment 122, makes things convenient for both to cooperatively interact, unlikely generation collision or interference.The thickness in plate end termination contact district 41 slightly is wider than this narrow slit 1221 between the folder type shell fragment 122.When cooperating with folder type shell fragment 122, plate end termination contact district 41 extend into narrow slit 1221 between the folder type shell fragment 122 by opening 25, because of the thickness in plate end termination contact district 41 width greater than narrow slit 1221, so folder type shell fragment 122 pushed outwards opening, simultaneously plate end termination contact district 41 is produced a clamping force (positive force), thereby realize connecting reliably.
Because the plastic body of line-end connector 10 of the present invention is that integral body slightly becomes square, and on the end face for 40 connections of plate terminal adapter, each folder type shell fragment 122 runs through the second surface 20 ' of this plastic body 2, therefore, the plate end termination contact district 41 of plate terminal adapter 40 must be correspondingly positioned at a certain side of off-center position on plate terminal adapter 40 end faces and could be just be inserted into narrow slit 1221 between each folder type shell fragment 122 by each opening 25, and realizes and being electrically connected of line-end connector 10.Thereby, play location and foolproof function when plate terminal adapter 40 is cooperated with line-end connector 10
More than the advantage of design is:
Can under the littler condition of size, realize the connection effect identical with conventional design (connector of large-size), and the reliability height of conducting; Because line end and plate end terminal sizes be little than the conventional type connector all, so its contact impedance is also littler, be conducive to for to the stricter product of loss requirement.
