The action and the effect of connector of the present invention then, are described.When blocking 1 from Fig. 1 or state shown in Figure 2 when inserting recess 21, the hypotenuse 1a and semi arch pawl 51 butts (with reference to Fig. 8) of card 1.When further insertion blocked 1, semi arch pawl 51 slided with respect to hypotenuse 1a and is pressed simultaneously.Then, under the state of the front-end edge butt of hypotenuse 1a and snap-latch piece 41, semi arch pawl 51 slides on the surface of card 1, at the recess 1b of card 1 outstanding (with reference to Fig. 8).In addition, on the front-end edge of snap-latch piece 41, be formed with inclined-plane with gradient identical with the hypotenuse 1a of card 1.Then, when pushing blocked 1, sliding part 4 moved (with reference to Fig. 3) to the inboard direction of recess 21.
As shown in Figure 6, thereby shift the end onto and block under 1 state that returns a little will blocking 1, the leading section 32a fastening of leaf spring 32 is in V-shaped valley A2.Its result, in the installation site of card 1, sliding part 4 is locked in (with reference to Figure 10 (D)) in the housing 2.In the installation site of the card 1 shown in Figure 10 (D), the semi arch pawl 51 that is arranged in the leading section of leaf spring 5 has the recess 1b of flexibly fastening at card 1, therefore, can keep the installment state (with reference to Fig. 9) of card 1 reliably.
When the installment state from card shown in Figure 91 pushes away when blocking 1, the leading section 32a of leaf spring 32 discharges from V-shaped valley A2, moves in backstroke (with reference to Figure 10 (E)).Then, sliding part 4 is compressed helical spring 6 application of forces, makes open 22 side shiftings of card 1 to recess 21.Relatively turn back to moment of the starting point A1 of heart type cam path 42 at the leading section 32a of leaf spring 32, sliding part 4 stops (with reference to Fig. 3).Here, though effect has inertia force on card 1,,, inadvertently eject so can prevent card 1 reliably because semi arch pawl 51 has flexibly fastening in the recess 1b of card 1.Then, by with stronger strength drawing card 1, card 1 is broken away from from connector 10.
Then, with reference to Figure 10 (A)～Figure 10 (G) relative motion between the leading section 32a of the sliding part 4 of cam path 42 with heart type and leaf spring 32 is described.
Figure 10 (A) is the state diagram before card 1 is installed in the connector 10, and the leading section 32a of leaf spring 32 is positioned at the starting point A1 of the cam path 42 of heart type.Figure 10 (B) is that card 1 inserts in the connector 10, sliding part 4 moves state diagram midway, an inclined-plane butt of the leading section 32a of leaf spring 32 and the cam path 42 of heart type.
Figure 10 (C) is the state diagram of further inserting card 1, and the leading section 32a of leaf spring 32 is along an inclined-plane displacement of the cam path 42 of heart type.In the state diagram shown in Figure 10 (C), leaf spring 32 the biggest ground deflections.Figure 10 (D) shifts card 1 end of onto, card 1 state diagram of returning a little, leaf spring 32 elastic recoveries, and the leading section 32a fastening of leaf spring 32 is in V-shaped valley A2.That is, can lock the installment state of (keeping) card 1.In addition, in this lock-out state, the effect (with reference to Fig. 3) of compression helical spring 6 performance assistance.
Figure 10 (E) thus be by pushing away the state diagram that the leading section 32a that blocks 1 leaf spring 32 discharges from V-shaped valley A2 from blocking 1 installment state.In the state diagram of Figure 10 (D), the leading section 32a of leaf spring 32 is residual the entad surplus energy of the backstroke elastic recovery of the cam path 42 of type.Because the leading section 32a of leaf spring 32 discharges from V-shaped valley A2, thereby the leading section 32a of leaf spring 32 moves to the backstroke of the cam path 42 of heart type.In addition, under the state of Figure 10 (E), strain does not take place in leaf spring 32.
Figure 10 (F) is that sliding part 4 is compressed helical spring 6 application of forces and is in recovery state diagram midway.The leading section 32a of leaf spring 32 is along another inclined-plane displacement of the cam path 42 of heart type.Leaf spring 32 is along another inclined-plane generation strain of the cam path 42 of heart type.Figure 10 (G) is the leading section 32a of leaf spring 32 relatively gets back to starting point A1 along the cam path 42 of heart type state diagram.Under the state of Figure 10 (G), sliding part 4 is compressed helical spring 6 application of forces and stops.Leaf spring 32 elastic recoveries turn back to the identical initial condition of state with Figure 10 (A).
Like this, the cam gear of sliding part 4 and the relative displacement of leaf spring 32 formation cams with driven member.And the track of the cam path 42 of heart type is described the not retrograde irreversible continuous path of leading section 32a of leaf spring 32 in whole stroke.
