The following describes the action when on the connector 1 of this example, plugging lead 100.As Fig. 1 (a), Fig. 2 (a) and shown in Figure 3, before connecting lead 100, be in the position that operating parts 5 is upright (with the position of support 31,41 nearly orthogonals of contact 3,4), in this state, because cam part 51 does not push the depressed part 36 of contact 3 downwards shown in Fig. 1 (a), therefore spring portion 32 does not produce strain, and the pawl 32a of spring portion 32 is to direction (upside) displacement of leaving the pawl 35a that plays contact pin 35.And shown in Fig. 2 (a), the depressed part 46 of thruster pressure contact 4 because cam part 52 does not make progress, so spring portion 42 does not in this state produce strain, and the pawl 42a of spring portion 42 is to direction (upside) displacement of the pawl 41a that leaves support 41.Therefore, rotate at operating parts 5 under the state of the non-anticreep position shown in Fig. 1 (a) and Fig. 2 (a), pawl 32a, the 42a of spring portion 32,42 is displaced to not and lead 100 position contacting, therefore can make lead 100 is inserted resistance force diminishes when connecting in the connectors 1, connect even the soft lead 100 of FPC and so on also can easily insert in the connector 1.In addition, operating parts 5 is rotated under the state of non-anticreep position, pawl 32a, the 42a of contact 3,4 also can be configured in lead 100 position contacting on, establish when inserting lead 100 and be electrically connected this moment, keep the confining force of lead 100 to be in relative less state but compare contact 3,4 when being positioned at the anticreep position, so lead 100 is in the state of relatively easily extracting with operating parts 5.
Operating parts 5 is rotated under the state of non-anticreep position, if insert mouthfuls 21 from lead lead 100 is inserted into the inside of connector body 2, lead 100 is inserted between the support 31,41 and spring portion 32,42 of contact 3,4 under guiding groove 24 guiding that upper and lower surface is provided with on by next door 23.Shown in Fig. 1 (b), when lead 100 further was inserted into connector body 2 inside, the leading section of lead 100 was connected on the positioning convex 37 of contact 3, by determining the position of the leading section of lead 100 with respect to contact 3,4 like this.
Under the state of the inside that lead 100 is inserted into connector body 2, if image pattern 1 (b), Fig. 2 (b) and the operating parts 5 that makes shown in Figure 4 rotate to position with support 31,41 almost parallels of contact 3,4, cam part 51 depressed parts 36 of pushing contacts 3 downwards shown in Fig. 1 (b) then, make spring portion 32 strains, pawl 32a by making spring portion 32 like this is to playing contact pin 35 1 sides (downside) displacement, conductor fig 101 (conductor part) Elastic Contact that the pawl 32a of spring portion 32 and lead 100 are provided with above.And this moment is shown in Fig. 2 (b), the depressed part 46 that cam part 52 upwards pushes contact 4 makes spring portion 42 strains, pawl 42a by making spring portion 42 like this with connecting portion 43 be fulcrum to support 41 1 side displacements, the conductor fig that is provided with above 101 Elastic Contact of the pawl 42a of spring portion 42 and lead 100.Therefore, rotate at operating parts 5 under the state of Fig. 1 (b), Fig. 2 (b) and anticreep position shown in Figure 4, because pawl 32a, the 42a of spring portion 32,42 are urged respectively on lead 100, therefore become lead 100 by the state that the crimping of contact 3,4 keeps, become lead 100 and be difficult to the state extracted relatively.And, pawl 32a by lead 100 being clamped in spring portion 32 and playing between the pawl 35a of contact pin 35, and lead 100 is clamped between the pawl 41a of the pawl 42a of spring portion 42 and support 41, makes between the conductor fig 101 of contact 3,4 and lead 100 to become the state that is electrically connected.
On the other hand, under lead 100 and state that connector 1 is connected, if make operating parts 5 rotate to non-anticreep position from the anticreep position, then the power of the depressed part 36,46 of cam part 51,52 extruding contacts 3,4 disappears, make pawl 32a, the 42a displacement upward of spring portion 32,42 by the elastic restoring force of spring portion 32,42, leave lead 100, so the power disappearance of contact 3,4 maintenance leads 100, can easily extract lead 100.
The connector 1 of this example adopts structure as described above, when inserting mouth 21 insertion leads 100 from lead, the positioning convex (location division) 37 that is provided with on the support 31 of the leading section of lead 100 and contact 3 connects, by determining the position of lead 100 so exactly with respect to contact 3,4, therefore can reduce the deviation of the clamping part and lead 100 contact positions of support 31,41 and spring portion 32,42, contact 3,4 electrically contacts at preposition and lead 100, can improve the reliability of electrical connection.
And, in this example since respectively with the spring portion 32,42 of multipole contact 3,4 cam part 51,52 of setting operation spare 5 accordingly, the spring portion 32 of the contact 3 of odd number lead-in wire upwards thruster presses cam part 51, cam part 52 is pressed in the spring portion 42 downward thrusters of the contact 4 of even number lead-in wire, therefore even be not provided with the bearing arrangement of operating parts 5 pivot suspensions on connector body 2, also can=rotate and freely make operating parts 5 pivot suspensions on the contact 3,4 that remains on the connector body 2.
Though be provided with the positioning convex 37 that carries out lead 100 location in the middle part of the support 31 of each contact 3 in the above-mentioned example, but the position that preferably operating parts 5 can not applied active force under state support 31, that inserting lead 100 when the anticreep position is swung in non-anticreep position because of the strain of contact 3 is provided with positioning convex 37, can suppress to impose on the power of lead 100 and make the position of lead 100 produce skew from positioning convex 37.In addition, if can obtain the contact pressure of predetermined value above contact 3 and lead 100, because the enough contact pressures of energy suppress the offset of lead 100, therefore the positioning accuracy at lead 100 satisfies in the scope of predetermined performance requirement, and it is also passable to apply active force for the position that is provided with positioning convex 37 by the strain of contact 3.
And, though only on contact 3, be provided with positioning convex 37 in this example, but because the broad position 102 of the conductor fig 101 of another contact 4 contacts is positioned at the rear side of lead direction of insertion as shown in Figure 6, the length dimension that the broad position 102 that contacts with contact 3 is compared on the lead direction of insertion is long, therefore even the position of contact 3 and contact 4 assemblings deviation a little on the lead direction of insertion also can make contact 4 firmly contact with the broad position 102 of conductor fig 101.In addition, inserting under the state of lead 100 operating parts 5 when the anticreep position is swung in non-anticreep position, if the active force that does not have contact 4 strains to apply, then can be in the contact location division that connects of the leading section of 4 one side settings and lead 100.
And, also can be with the fabric switch of contact 3 with the contact 4 of even number lead-in wire of odd number lead-in wire.
And, though the clamping part (pawl 32a, 42a) that is provided with in conductor fig 101 that lead 100 is provided with above and the spring portion 32,42 is electrically contacted, also can be that support 31,41 1 sides clamping part (playing the pawl 35a of contact pin 35 and the pawl 41a of support 41) that is provided with and the conductor fig that lead 100 is provided with below electrically contact.
Though above is that the center is illustrated with certain embodiments of the present invention, but can in aim of the present invention and the claim scope of adding, carry out various distortion, change or correction in the present technique field, therefore above-mentioned explanation and accompanying drawing do not limit technological thought of the present invention, and can only be interpreted as is example of the present invention.
