Case portion 9, in the square tube shape slenderly extended at bearing of trend, is formed at the front side of bearing of trend and rear side all openings.Cross sectional shape during the observing from bearing of trend of case portion 9 is substantially rectangular shape.Case portion 9 comprises: base plate 91, and it extends along bearing of trend; Pair of side plates 92,93, two acies of its Width from this base plate 91 are holded up to short transverse; Top board 94, its jag from a side plate 92 among these side plates 92,93 (acies) is bent to form towards another side plate 93, is set to relative with base plate 91; And outside plate 95, it is bent to form in the mode in the outside being overlapped in top board 94 from the jag of another side plate 93.
As shown in Figure 2,3, the base plate 91 in case portion 9 is formed with the locking lance hole 12 (engaged part) arranged communicatively with the inside of female end 3.As shown in Figure 3, locking lance hole 12 is substantial middle position peristomes of being formed of overall with ground throughout the Width of base plate 91 of bearing of trend in case portion 9, and base plate 91 is divided into the part of the front side of bearing of trend and the part of rear side by locking lance hole 12.Locking lance hole 12 is made: under the state that female end 3 is accommodated in the normal position in accommodating chamber 4, the locking lance 7 being arranged at accommodating chamber 4 can enter, and is made: the locking surface 71b of locking lance 7 can be locked to the front end face 12a (with reference to Fig. 5) on front side of the bearing of trend engaging lance hole 12.
Further, particularly in the present embodiment, as shown in Figure 2,3, the substantial middle position of among the outer rim in locking lance hole 12, on front side of bearing of trend part, the mode that (on the downside of short transverse) is outstanding with is laterally formed with jut 13.In other words, jut 13 be formed on locking lance hole 12 outer rim among, to be received in accommodating chamber 4 normal position at female end 3 before the part that abuts with the inclined plane 71a of locking lance 7.In addition, the rear end face 13a on rear side of the bearing of trend of jut 13 is formed along the front end face 12a in locking lance hole 12.Namely, be configured to: the rear end face 13a of jut 13 forms same plane with the front end face 12a in locking lance hole 12, when engaging lance 7 and being embedded in female end 3, the rear end face 13a of the jut 13 and front end face 12a in locking lance hole 12 abuts with the locking surface 71b of locking lance 7.
Next, the insert action of female end 3 in the female connector 1 of present embodiment is described with reference to Fig. 4,5.Fig. 4 be illustrate in the insert action of female end of present embodiment insertion force be the state of maximum, the longitudinal section of female connector.Fig. 5 be illustrate in the insert action of female end of present embodiment female end be accommodated in the state of the normal position in accommodating chamber, the longitudinal section of female connector.
First, as shown in Figure 2, by the direction of insertion of female end 3 on front side of bearing of trend, insert from the sub-insert port 5 of the female end of cloudy housing 2 to accommodating chamber 4, when advancing in the inner space of accommodating chamber 4 along direction of insertion, the front end of female end 3 abuts with the inclined plane 71a of the engaging claw 71 of locking lance 7.Because female end 3 is connected to the locking lance 7 be projected in accommodating chamber 4, thus for the further movement to direction of insertion, be subject to the resistance from locking lance 7.Therefore, from after female end 3 abuts with locking lance 7, need to make female end 3 be inserted into the insertion force of the size of needs in accommodating chamber 4 further from direction of insertion to the resistance that female end 3 applies to produce to overcome locking lance 7.In the following description, the MIN external force that the resistance produced to overcome locking lance 7 makes female end 3 require along bearing of trend (particularly direction of insertion) movement in accommodating chamber 4 is expressed as " requiring insertion force ".This require insertion force according to female end son 3 with engage lance 7 contact site, contact direction change and successively change.In addition, this requires insertion force also can be expressed as the external force for the direction of insertion putting on female end 3 and the reaction force (drag) produced.
Utilize this to require insertion force, the inclined plane 71a of locking lance 7 presses to direction of insertion by female end 3, thus inclined plane 71a produces component locking lance 7 entirety pressed down on the downside of short transverse, engages lance 7 due to this component to adjacent space portion 8 side deflection deformation.Female end 3, while utilize the requirement insertion force applied to make locking lance 7 deflection deformation (strain), is inserted in accommodating chamber 4 constantly.Along with female end 3 advancing in accommodating chamber 4, the position of female end 3 that the inclined plane 71a of locking lance 7 contacts is according to the order transition of the front end in case portion 9, base plate 91, jut 13.Then, as shown in Figure 4, abut with the jut 13 of female end 3 at the locking inclined plane 71a of lance 7, engage claw 71 from the state that accommodating chamber 4 keeps out of the way adjacent space portion 8, require that insertion force becomes maximum P1 (with reference to Fig. 6), the deflection deformation amount (elastic deformation amount) engaging lance 7 subsequently becomes maximum.Now, as shown in Figure 4, the electric wire calking portion 11 of female end 3 gives prominence to from the sub-insert port 5 of female end.
After the requirement insertion force of female end 3 becomes maximum P1, owing to requiring that insertion force becomes below maximum P1, therefore, the insert action of female end 3 moves to the state (female end 3 is accommodated in the state of the normal position in accommodating chamber 4) that the insert action shown in Fig. 5 is over because of inertia quickly.More specifically, when the end on front side of the bearing of trend that the jut 13 of female end 3 crosses the inclined plane 71a of locking lance 7 and when entering on front side of bearing of trend from engaging claw 71, become locking lance 7 elastic reset of free state, engaging claw 71 is embedded in the locking lance hole 12 of female end 3, further, engage the locking surface 71b of claw 71 to abut with the front end face 12a in locking lance hole 12 of female end the 3 and rear end face 13a of jut 13.Now, the electric wire calking portion 11 of female end 3 is received in accommodating chamber 4 completely by from the sub-insert port 5 of female end.
Herein, the insert action of female end 3 of present embodiment is further illustrated with reference to Fig. 6.Fig. 6 is the requirement insertion force of female end, the figure with the relation of stroke (female end 3 is to the insertion of accommodating chamber 4) in the insert action of female end that present embodiment is shown.The longitudinal axis of Fig. 6 represents and requires insertion force [N], and transverse axis represents stroke [mm].In addition, the positional representation that female end 3 starts to contact with the inclined plane 71a of the locking lance 7 in accommodating chamber 4 by the stroke of the transverse axis of Fig. 6 is D0.
As shown in Figure 6, when contacting with the inclined plane 71a of the locking lance 7 in accommodating chamber 4 in the front end in case portion 9 of stroke D0 place female end 3, in order to make locking lance 7 deflection deformation to enter to depth side further, need to pay requirement insertion force to direction of insertion to female end 3.Whenever the stroke of female end 3 increases, the deflection deformation amount namely engaging lance 7 increases, and this requires that insertion force just increases gradually, becomes maximum P1 at stroke D1 place.The trip D1 is the state shown in above-mentioned Fig. 4, is the state that abuts with the jut 13 of female end 3 of the locking inclined plane 71a of lance 7, be female end 3 bearing of trend on rear side of the part state of giving prominence to from the sub-insert port 5 of female end.The stroke D2 that stroke D1 is received in accommodating chamber 4 than the entirety of female end son 3 is little.That is, stroke D1 is included in female end 3 from the outstanding scope of cloudy housing 2.In other words, in the present embodiment, before requiring that the maximum P1 of insertion force produces in the accommodating chamber 4 that the entirety of female end 3 is received into cloudy housing 2.
In addition, owing to engaging the impact etc. of shape of the engaging claw 71 of lance 7, in the present embodiment, in the insert action of female end 3, it is different that the moment requiring insertion force to become maximum P1 and the deflection engaging lance 7 become maximum moment.As shown in Figure 6, after the requirement insertion force of stroke D1 place female end 3 becomes maximum P1, the deflection that there occurs the stroke D3 place locking lance 7 of progress in the insertion of female end 3 becomes maximum.Then, the insert action that there occurs stroke D4 place female end 3 of progress in the insertion of female end 3 further completes.The trip D4 is the state shown in above-mentioned Fig. 5, is engaging claw 71 state chimeric with the locking lance hole 12 of female end 3 of locking lance 7.
In the present embodiment, as an example of the formation of the characteristic for realizing requirement insertion force as shown in Figure 6 and stroke, the outer rim in the locking lance hole 12 of female end 3 is provided with jut 13.This jut 13 is in order to realize the characteristic shown in Fig. 6, and its shape, size equal-specification set corresponding to the shape of the inclined plane 71a of the locking lance 7 such as contacted in insert action.That is, jut 13 is taken into account and the shape ground engaging lance 7, is formed with the contact site with locking lance 7.
Next, the effect of the female connector 1 of present embodiment is described.The female connector 1 of present embodiment comprises: accommodating chamber 4, and it extends in the inside of cloudy housing 2 and be formed hollow form, has the sub-insert port 5 of female end at the rear side of bearing of trend; And female end 3, it can be inserted into the inside of accommodating chamber 4 from the sub-insert port 5 of female end along bearing of trend.Female connector 1 is in order to be received into the predetermined normal position of the bearing of trend in accommodating chamber 4 by female end 3, and the female end contacted with each other in insert action 3 is formed as with the contact site of accommodating chamber 4: in the insert action of inserting from the sub-insert port 5 of female end, female end 3 can be made to become maximum P1 in a part for female end 3 from the position (stroke D1) that the sub-insert port of female end 5 is outstanding in the requirement insertion force of bearing of trend movement.Specifically, arrange communicatively with the inside of female end 3 and normal position with among the outer rim in the chimeric locking lance hole 12 of locking lance 7, female end 3 arrive normal position before with engage the position that lance 7 abuts and be provided with jut 13.
Herein, as shown in Figure 6, in the insert action of female end 3, if the external force being equivalent to the maximum P1 of requirement insertion force at stroke D1 place puts on female end 3, then inertia can be utilized to make female end 3 be inserted into the normal position (stroke D4) of accommodating chamber 4 after.On the contrary, think the characteristic of such insert action, when the external force that stroke D1 place puts on female end 3 is less than the maximum P1 of predetermined requirement insertion force, inertia can not be utilized afterwards to make the final normal position arrived in accommodating chamber 4 of female end 3, and female end 3 can become midway insert state relative to cloudy housing 2 (accommodating chamber 4).Under the insert state of midway, bad owing to likely coming in contact between terminal when connector uses, therefore, wishing can the midway insert state of visual confirmation female end 3.
To this, in the present embodiment, utilize above-mentioned formation, in the insert action of female end 3, the requirement insertion force of female end 3 is set to become maximum in a part for female end 3 from the position (stroke D1) that the sub-insert port of female end 5 is outstanding.Thus, when female end 3 is not inserted into the normal position in accommodating chamber 4, because the part on rear side of the bearing of trend of female end 3 is given prominence to from cloudy housing 2, therefore, it is possible to well visual confirmation female end 3 to the midway insert state of accommodating chamber 4.
In addition, in the present embodiment, jut 13 is set by the outer rim in the locking lance hole 12 at female end 3, thus can makes to require that insertion force is maximum P1 from the position that the sub-insert port of female end 5 is outstanding in a part for female end 3.Utilize this formation, just can realize the characteristic of the insertion force expected by means of only the improvement carrying out arranging jut 13 on female end 3.In addition, due to new inscape can not be added especially on cloudy housing 2, therefore, it is possible to adopt the product both deposited.So, the raising of productivity ratio and the minimizing of manufacturing cost can be realized.
In addition, same plane is formed with the front end face 12a in locking lance hole 12 because jut 13 is formed rear end face 13a, therefore, when engaging lance 7 and being embedded in female end 3, the rear end face 13a of the jut 13 and front end face 12a in locking lance hole 12 abuts with the locking surface 71b of locking lance 7.That is, by arranging jut 13, thus the area that the locking surface 71b that can increase locking lance 7 contacts with female end 3, the locking degree of depth engaging lance 7 can be guaranteed fully.Thus, because terminal retention (utilizing the power that female end 3 is locked on the power (anticreep power) in accommodating chamber 4 or needs to be pulled out from accommodating chamber 4 by female end 3 be locked in accommodating chamber 4 by locking lance 7) increases, therefore, it is possible to make female end 3 firm to the locking state in accommodating chamber 4 further.
