DESCRIPTION OF THE PREFERRED EMBODIMENT
Figure 1 6how6 an existing connector of the type to which this device belon~6. The connector con6i~t~ of the frame-shaped component 1 and the 3L2~13~1~
s pre66ure insertion component 6, both of which are jade of insulating materials. Multiple--.in6ertion chamber6 2, for the purpose of inverting the re~ilie~t connecting component (the component 9 6hown S in figure 2~ are set at equal interval from each other, being separated by the pareition~ pa and 4b which are formed a6 ridge from the long walls 3a and 3b. The groove 5 or the purpose of receiving the printed wiring circuit board i6 provided along the direction of the length of the ~rame-6haped component 1 between the partitions 4a and 4b. The dovetailing projections 8. which fit into the in6ertion chambers 2 of the frame-6haped component 1. are set like the teeth of a comb in the pre~6ure insertion component 6. In the mode 6hown in the figure, the dovetailing pro3ections 8 are wormed into a single entity with the backplate (hereafter called the working plate~7 a a ridge. A gap i6 provided in the frame-haped ~o~ponent 1 between the lonq wall 3a and the partition 4a for the purpo6e of inverting the working plate.
The flexible pla6tic insertion 6top devices 12 are installed at both ends of the pressure in6ertion component 6 and the stop frame devices 11 that receive and 6top the aforementioned plastic insertion top devices 12 are in6talled on both ends of the frame-~haped component 1.
Figure 2 i6 a crow ection 6howing a state in which termination of connecting lead wire has been achieved by placing the printed wiring circuit lead wire 13 between the aforementioned frame component and the pres6ure in6ertion component. The resilient connecting component 9, which was mentioned previou61y, it a fine metal band bent into an S
6hape. A fir6t end i8 extended in a ~traighe line Jo ~139~
a to come into resilient contact with the convexly curved pOltiOn 9a of the I. The second end alto ha a shape that is extended parallel Jo said straight line. The second end pierces the bottom of each S insertion chamber 2 of the frame-~haped component 1 and lead to the outside. The initial convexly curved portion 9a, which it continuous with thi6 6econd end, it inverted and fixed so that it faces the inneL wide of the frame-sAaped component 1.
When the printed wiring lead wire 13 i6 connected with this type of connector, the lead wires aye printed in parallel and ae equal inter~al~ on the printed circuit board. It qoes without 6aying that the in6ertion chambers 2 ox the frame-~haped component 1 are jet at interval congruent with those of the pcinted wiving lead wirefi.
ln order to connect the printed wiring lead wire 13 with a connector 6uch as described above, the printed wiring board (which 6hould be lexible) 13 i8 inserted Jo that the wiring come6 into contact with the convexly curved portion ga of the ~e~ilient connecting component 9. Following that, the pre~6ure in6ertio~ component 6 is in6er~ed 50 that the dovetailing projections 8 with lead in edgeR 14 fit into the in6ertion chambers. Since the thicknes~e~
ox the dovetailing projection6 are jet Jo a6 to be e66entially equal to the thickne~es of the paLtition~ 4a of the frame-fihaped component 1, the doveeailing p ojection~ compresses the extended porLion of the first end of the resilient connecting component into which the printed wiring circuit board is in6~rted from the bask. In order to complete the contact between the lead wire and the elastic connecting component, the small projection 9b. which ~5 face6 the convexly curved portion, i6 jet in the Z~3~
re~ilien~ connecting component 9 at the point at which the extended portion of the first end comes into contact with the convexly curve,d portion that is continuous wit the second end. Further the 6mall projection 9c is jet on the oppo6ite 6ide near the tip, i.e., Pacing the dovetailing ~roject;on.
Con6equently, contact between and fixing of the lead wise and the resilient connecting component are completely achieved by inserting the pre6sure in~eetion component into the frame-6haped component.
However, a wa6 indicated previously, when connection is performed u6ing thi6 apparatus, contact between all of the dovetailing projection6 and (the 6mall projection6 9c of) the elastic connecting components begins at the tame time, the force required for insertion increa6e~ abruptly, with difficulty in operation occurring. when the working plate (backplate 7) i6 not pre6ent, a discrepancy occur6 in the adjustment between the dovetailing projection6 and the in6ertion chambers at the time of insertion. Thi6 device i8 one in which the aforementioned drawback of the conventional technology i8 eli~ina~ed.
The di6tinctive characteristic of this device i6 the shape of the pressure insertion projection6. In other re~pect6, it is es6entially the tame as the conventional technology described in the foregoinq text. Figure 3 it a per6pective view 6howing the 6hape of a pressure insertion component of an apparatu6 thaw i8 a suitable mode of execution of thi6 device. Thi6 pre sure insertion component i8 e~eneially identical in 6hape to that explained by Leference to Figure 2. However, the two end projections Ba end Bb of the dovetailing projections are made a the longest, with the projections ~Z~L~ 397 - becoming shorter from projection 8c. which is next Jo 8b.
Thy frame-~haped component corr2~ponding to it i6 identical to that shown in Figuce 1. By providing a structure of this kind, the long dovetailing projections 8a and 8b with the lead in 14a a the two end6 function as guides when the pre6sure insertion component i6 inserted into the frame-~haeed component. Insertion begin in 6equence from 8c, with overall insertion proceeding extremely 6moothly. Thu6, occurrence of twitting due to high inserti.on pressure forces and damage to the components as a result of twisting are prevented.
The foreqoing concrete example ifi a 6uitable mode of execution However, this device i6 not limited to this mode, being limited only as described in the claims.
