In the present embodiment, the first terminal 51 is formed by metallic plate and the first pedestal 11 is formed by resin, the first terminal 51 Body 52 size in the longitudinal direction more than the first pedestal 11 terminal body receiving space 17 in the longitudinal direction Size.Therefore, when the first terminal 51 is loaded into the first pedestal 11 and body 52 is contained in terminal body receiving space 17, should Power is acted on and is formed with the sidepiece 12 of terminal body receiving space 17, and the deformation of the sidepiece 12 of the left and right sides is as shown in Figure 6.

More specifically, the size from the rear end 58re of the front end 58fe to rear fixed part 58r of front fixed part 58f is more than From the rear contact site 26re's of the front contact site 26fe to rear fixed part accepting groove 26r of front fixed part accepting groove 26f Size, therefore rear contact site 26re pressed first backward.As a result, stress acts on rear wall portion 22r and central portion 21 first Between coupling part, and sidepiece 12 deforms, and thus rear wall portion 22r locks the first rear centered on the coupling part Determine portion 16r to be rotated up towards a side of the width center deformation of the first pedestal 11.

As can be seen that constituting the rear arm 23r that rear wall portion 22r is connected to the part of central portion 21 from Fig. 4 and Fig. 6 In left and right directions（That is the width of the first pedestal 11）It is upper that there is less size, that is, it is narrower than the front arm of front wall portion 22f The size of portion 23f.But base plate 14 is not attached to the bottom of rear arm 23r, base plate 14 is connected to from central portion 21 The bottom of the scope between the centre of rear end to front arm 23f.Additionally, the rear contact site of rear fixed part accepting groove 26r 26re is located behind the position of the part in arm 23r connecting bottom boards portion 14 and rear wall portion 22r and central portion in the longitudinal direction The rear of the position of the coupling part between 21, the position and front of the front contact site 26fe of front fixed part accepting groove 26f The position of the part in arm 23f connecting bottom boards portion 14 is substantially the same.Therefore, the rigidity of rear wall portion 22r of the left and right sides is low It is in front wall portion 22f and yielding, thus by with the coupling part of central portion 21 centered on rotate.

Therefore, when the body 52 of the first terminal 51（The body 52 of the first terminal 51 size in the longitudinal direction is big In the size of the terminal body receiving space 17 of the first pedestal 11）When in insertion terminal body receiving space 17, and front is fixed Space quilt between the rear contact site 26re of the front contact site 26fe and rear fixed part accepting groove 26r of portion accepting groove 26f Push away when broadening, the stress applied by the body 52 of the first terminal 51 is first（primarily）Act on rear wall portion 22r and in Coupling part between centre portion 21, and deform generation, thus rear wall portion 22r is rotated around coupling part, as shown in Figure 6.

Fig. 6 illustrates the exaggerated views for readily appreciating.Similarly, that possibly cannot significantly perceive sidepiece 12 makes rear The deformation that wall portion 22r is rotated.But, even if deformation as shown in Figure 6 significantly cannot be perceived, by the body of the first terminal 51 Coupling part of the stress that portion 52 applies between rear wall portion 22r and central portion 21.In other words, in spite of obvious Perceive deformation as shown in Figure 6, the preloading that the body 52 of the first terminal 51 applies locks the first rear Portion 16r acts on rear wall portion 22r towards on a direction of the width center deformation of the first pedestal 11（Including the first rear Sticking department 16r）.Again in other words, for being applied by the body 52 for housing and being secured in place in terminal body receiving space 17 Preloading acts on the first rear sticking department 16r on one with latch-release direction in opposite direction.

Therefore, the first rear sticking department 16r rigidity is high and is difficult outwards to deform in the width of the first pedestal 11.Also It is to say, the distance between first rear sticking department 16r of the left and right sides is difficult increase.This causes to release and docks space 13 with insertion In the engagement of the second rear sticking department 116r of the second pedestal 111 of the second connector 101 become difficult.

Next, the composition of the second connector 101 of explanation.

As illustrated, the second pedestal 111 is provided with a top plate portion 114 of the global shape with a flat Nogata body, And the flat top plate portion 114 of general rectangular is connected to the upper surface of body 113.Top plate portion 114 is in the longitudinal direction Size of the size with body 113 in the longitudinal direction is substantially the same, and the front-end and back-end of top plate portion 114 and body 113 Front-end and back-end be generally in same position, but the size in the direction of the width of top plate portion 114 more than body 113 in width Size on degree direction, and the two side ends of top plate portion 114 project the two side ends for running off body 113 further out.Therefore, when When releasing the docking of the first connector 1 and the second connector 101, an instrument or utensil（Such as one small-sized screwdriver）Front end Portion can touch the lower surface for crossing the top plate portion 114 that the two side ends of body 113 are projected further out, hold operator Change places and release the docking of the first connector 1 and the second connector 101.The leading section of instrument or utensil also can contact and be formed at this The recess 113a of the front surface in body portion 113.

The two elongated parallel channel-shaped electric wire accommodating recess 112 for extending in the longitudinal direction are formed at body 113 Lower surface（That is butting surface（Upper surface in Fig. 8））.The rear end of electric wire accommodating recess 112 and the lower surface opening, and Upper surface, front end and both sides by top plate portion 114 and be included in body 113 an antetheca 121c, central wall 121a and Side of sidewall portion 121b is limited.

Front electric wire grasping foot 155f and rear electric wire for accommodating second terminals 151 grasps the composition of foot 155r The front pin accepting groove 122f and rear pin accepting groove 122r of pin accepting groove is formed at central wall 121a's and side of sidewall portion 121b Towards the side surface of electric wire accommodating recess 112.Front pin accepting groove 122f and rear pin accepting groove 122r is from central wall The groove-like recess of the upwardly extending rectangle of the lower surface of lower surface and side of sidewall portion 121b of 121a, and the lower surface and direction electricity The side surface opening of line accommodating recess 112.The connecting portion 156 of rear pin accepting groove 122r also accommodating second terminals 151；Therefore, The width of rear pin accepting groove 122r（Size i.e. in the longitudinal direction）More than the width of front pin accepting groove 122f.

Contact site collecting slit 127 for the contact site 157 of accommodating second terminals 151 is formed at side of sidewall portion 121b.Connect It is to upwardly extend from the lower surface of side of sidewall portion 121b and the insertion on the width of the second pedestal 111 that contact portion houses slit 127 The recess of the elongated slit-shaped of side of sidewall portion 121b, be formed at correspondence rear pin accepting groove 122r position and make side of sidewall portion The face in the outside of 121b is connected with rear pin accepting groove 122r.

Body 113 is provided with front of the one of the composition end wall stretched out on the width of the second pedestal 111 End wall 124f and rear end wall 124r.Before front end wall 124f and rear end wall 124r are connected to side of sidewall portion 121b End and rear end, and further outwardly beyond the outer surface of side of sidewall portion 121b on the width of the second pedestal 111.Cause This, is formed in front end wall 124f and rear in the opposed, inwardly directed recessed guide recess 128 of the width of the second pedestal 111 Between end wall 124r.In the example shown in figure, the front surface of antetheca 121c is concordant with the front surface of front end wall 124f.

The outer surface of front end wall 124f and rear end wall 124r on the width of the second pedestal 111 is constituted One front outer surface 115f and a trailing outside surface 115r, front outer surface 115f and trailing outside surface 115r are constituted Be formed in the first connector 1（Dock with the second connector 101）The first pedestal 11 in the first front sticking department 16f and The inner surface of one rear sticking department 16r（Front end face）Towards outer surface.Second front sticking department 116f and the second rear Sticking department 116r is formed at the lower end of front outer surface 115f and trailing outside surface 115r（Upper end in Fig. 8）Near, make For the second sticking department on the width of the second pedestal 111 outwardly.Second front sticking department 116f and the second rear lock The the first front sticking department 16f and the first rear sticking department for determining portion 116r and being formed in the first pedestal 11 of the first connector 1 16r is engaged.

Guide recess 128 is the channel-shaped space for extending up and down, and three sides in the channel-shaped space are by side of sidewall portion 121b, forward end Wall portion 124f and rear end wall 124r are limited, and the downside in the channel-shaped space and the width side towards the second pedestal 111 Lateral opening laterally.Thus, when the first connector 1 and the second connector 101 are docked, it is formed in the of the first connector 1 Front guide portion 28f and rear guide portion 28r in one pedestal 11 enters guide recess 128, thus guides body 113.Draw The guide plane 128a for leading the outer surface that side of sidewall portion 121b is constituted in recess 128 is the front guide portion with the first pedestal 11 The inner surface of 28f and rear guide portion 28r（Front end face）Towards surface.

Contact site houses slit 127 and is open to guide plane 128a, and constitutes the edge of at least side end of contact site 157 Portion 157a protrudes into guide recess 128, and contact site 157 is connected to the Second terminal being housed in contact site collecting slit 127 151 connecting portion 156.Terminal limit convex portion 118 be formed at contact site house front side of the slit 127 on guide plane 128a and Rear side.It is projection of bootstrap plane 128a on the width of the second pedestal 111 outwardly that terminal limits convex portion 118 Portion, and terminal limits the elongated jut that convex portion 118 is that the opening above-below direction for housing slit 127 along contact site extends.The The edge part 157a of the contact site 157 of two-terminal 151 further projects outwardly beyond end on the width of the second pedestal 111 Son limits the side surface 118a of convex portion 118.When the first connector 1 and the second connector 101 are docked, terminal limits convex portion 118 Into the terminal guide recess 18 being formed in the first pedestal 11 of the first connector 1, body 113 is thus guided.

When the first connector 1 and the second connector 101 are docked, the edge part 157a of the contact site 157 of Second terminal 151 The contact site 57 of the first terminal 51 of the first connector 1 is contacted, specifically, the top 57a of contact site 57 protrudes into terminal and draws Lead recess 18.Now, the contact site 157 of Second terminal 151 suffers that the contact site 57 of the first terminal 51 presses, thus towards second The width center deformation of pedestal 111.But, if 57 contact terminal of contact site of the first terminal 51 limits convex portion 118 Side surface 118a, then they will not further deform towards the width center of the second pedestal 111.That is, the Deformation of the contact site 157 of two-terminal 151 on the width of the second pedestal 111 is limited convex portion 118 by terminal and limits, and The amount of deformation will not be over the degree that edge part 157a protrudes from side surface 118a.

Preferably, the various pieces of Second terminal 151（Including edge part 157a）On the width of the second pedestal 111 It is prominent less than front outer surface 115f and trailing outside surface 115r further out.It is further preferred that Second terminal 151 Various pieces project the lower surface less than central wall 121a and side of sidewall portion 121b further downward.When described two in succession When connecing device, this prevents the finger of operator from contacting Second terminal 151, so as to prevent damaging Second terminal 151.

The lower surface and rear end wall 124r of central wall 121a are connected to including the electric wire stop part 131 of fin 131a Inner surface on the width of the second pedestal 111.Fin 131a is located at the electric wire near the rear end of body 113 and houses The lower section of recess 112, and the both sides being set to from electric wire accommodating recess 112 in the direction of the width are oblique towards the center of width Project upwards.The front end relative to each other below electric wire accommodating recess 112 of fin 131a is separated from one another, between them Distance the external diameter for being smaller in size than the electric wire 191 for being contained in electric wire accommodating recess 112.Fin 131a being capable of elastic deformation.

From the shape of the fin 131a shown in Fig. 8 can be seen that when electric wire 191 from the lower section of the second pedestal 111 it is relative to Upper movement and insert corresponding electric wire accommodating recess 112 when, electric wire 191 easily by below electric wire accommodating recess 112 each other Relative fin 131a.But, once electric wire 191 is contained in electric wire accommodating recess 112, they are by before relative fin 131a End resistance is kept off, and thus prevents electric wire towards the relative movement of the downside of the second pedestal 111, receives so as to prevent electric wire 191 from departing from electric wire Hold recess 112.

It is the part being integrally formed by bending and one conductive metal sheet of punching press according to the Second terminal 151 of the present embodiment, As shown in figure 9, and being provided with：Flat body 152；Front electric wire grasping part 153f, is connected to the one of body 152 End；Rear electric wire grasping part 153r, is connected to the other end of body 152 via connecting portion 156；And contact site 157, connection In the side of connecting portion 156.

Front electric wire grasping part 153f is substantially tuning fork-like or even a forked part, and the base portion of the part includes：Before Square electric wire grasps foot 155f, constitutes a pair and grasps foot towards the electric wire that front end projects；And front electric wire fixing spatial portion 154f, composition are formed in the space of the slit-shaped between the electric wire grasping foot 155f of front.The shape of rear electric wire grasping part 153r Shape is substantially the same with the shape of front electric wire grasping part 153f, and including：Rear electric wire grasping foot 155r, constitutes a pair of electric wires Grasping foot；And rear electric wire fixing spatial portion 154r, constitute the slit being formed between the electric wire grasping foot 155r of rear The space of shape；Rear electric wire grasping foot 155r is connected to connecting portion 156.Connecting portion 156 includes the connection of the heart formed therein Spatial portion 158.Connection space portion 158 is connected with rear electric wire fixing spatial portion 154r, but holds spatial portion than rear electric wire 154r width.

Such as Fig. 9（b）Shown, front electric wire grasping part 153f is bent into and is generally normal to body 152, and connecting portion 156 is curved It is converted into and is generally normal to body 152 and substantially upwardly extending with front electric wire grasping part 153f identical sides, and rear is electric Line grasping part 153r substantially bends 180 ° with overlap with connecting portion 156 relative to connecting portion 156.Therefore, front electric wire grasping part Toward each other, distance relative to each other is identical with the anterior-posterior length of body 152, and connects for 153f and rear electric wire grasping part 153r Contact portion 157 is located behind the outside parallel to rear electric wire grasping part 153r of electric wire grasping part 153r.The edge of contact site 157 Portion 157a is being upwardly extended with 155r identical sides of rear electric wire grasping foot.

Fig. 9（b）It is the view similar in appearance to Fig. 8, wherein the second pedestal 111 is removed.It is loaded on the right side of the second pedestal 111 The contact site 157 of Second terminal 151 is connected to the right-hand member of connecting portion 156, and is loaded into the contact site of the Second terminal 151 in left side 157 left ends for being connected to connecting portion 156.That is, being loaded into the Second terminal 151 on right side and being loaded into second end in left side Son 151 has different shapes.

When Second terminal 151 is loaded into the second pedestal 111, bottom surface of the body 152 towards electric wire accommodating recess 112, Front electric wire grasping foot 155f and rear electric wire grasping foot 155r are contained in front pin accepting groove 122f and the collecting of rear pin Groove 122r, and contact site 157 is contained in contact site collecting slit 127.Now, it is formed on the outside of the electric wire grasping foot 155f of front The recess and jut of end and rear electric wire grasping foot 155r outboard ends is snapped at front pin accepting groove 122f and rear pin receipts Tank 122r, so as to front electric wire grasping part 153f and rear electric wire grasping part 153r be securely fixed it is in place.

The width of front electric wire fixing spatial portion 154f and rear electric wire fixing spatial portion 154r is preferably substantially equivalent to or little In the heart yearn of electric wire 191（It is not shown）External diameter.Thus, when the part of the electric wire 191 for being contained in electric wire accommodating recess 112 is pressed When entering front electric wire fixing spatial portion 154f and rear electric wire fixing spatial portion 154r, the insulating cover of electric wire 191 is by front Electric wire grasps foot 155f and the interior ora terminalis of rear electric wire grasping foot 155r breaks, so as to the heart yearn of electric wire 191 is electrically connected to Front electric wire grasping foot 155f and rear electric wire grasping foot 155r.

When the first connector 1 and the second connector 101 are docked, the contact site with the first terminal 51 of the first connector 1 57 contact causes the contact site 157 of Second terminal 151 pressurized and towards the width center deformation of the second pedestal 111.This Kind of pressure and deformation from contact site 157 via rear from connecting portion 156 to the contact site 157 near rear electric wire grasping part 153r Electric wire grasping foot 155r transmission.Electric wire grasping foot 155r in rear is thus towards rear electric wire grasping foot 155r to quilt Press and deform, thus the heart yearn of electric wire 191 is effectively grasped by rear electric wire grasping foot 155r on both sides, so as to more may be used Maintain the electrical connection of foot 155r is grasped with rear electric wire by ground.

Next it will be described for the docking operation of the first connector 1 with above-mentioned composition and the second connector 101.

Now, the afterbody 53 of the first terminal 51 of the first connector 1 is welded in the connection being formed on the surface of substrate 91 Device electrode portion 93, so as to the first connector 1 to be installed on the surface of substrate 91.The Second terminal 151 of the second connector 101 connects The terminal of terminal wires 191 is connected to, so as to the second connector 101 to be connected to the terminal of electric wire 191.

As shown in figure 1, operator makes the upper surface of the first connector 1（Butting surface）With the following table of the second connector 101 Face（Butting surface）To, move towards each other the first connector 1 and/or the second connector 101, and by the second connector The body 113 of 101 the second pedestal 111 is inserted in the docking space 13 in the first pedestal 11 of the first connector 1, so as to First connector 1 and the second connector 101 are docked.

In this process, front guide portion 28f of the first pedestal 11 and rear guide portion 28r insert the second pedestal 111 Guide recess 128, so as to guide the body 113 of the second pedestal 111.Relative to the first pedestal 11, the second pedestal 111 is front Thus relative position in rear direction and left and right directions is defined, and prevents displacement（I.e. relative to the first pedestal 11, the second pedestal 111 rocking in back and forth or left and right direction（rattling））.

The terminal of the second pedestal 111 limits the terminal guide recess 18 that the first pedestal 11 is inserted in convex portion 118, so as to guide the The body 113 of two pedestals 111, and the side surface 118a that convex portion 118 is limited from terminal of the contact site 157 of Second terminal 151 The prominent top 57a in terminal guide recess 18 of prominent edge part 157a contact contact sites 57.The first terminal 51 and Thus two-terminal 151 turns on one status of electrically connecting of formation, so as to turn on the connection electric wire 191 that is connected with Second terminal 151 and with Substrate 91（The afterbody 53 of the first terminal 51 is connected to substrate 91）On the conductive trace that connected with electrode portion 93 of connector.

Because edge part 157a extends in the vertical direction, when the body 113 of the second pedestal 111 enters the first pedestal 11 Docking space 13 when, the top 57a of contact site 57 is moved from the lower end of edge part 157a relatively upward along edge part 157a, together When keep one to compress the state that contacts with edge part 157a due to bending 57a at the top of the elastic reaction of arm 56.So, contact site 57 top 57a and edge part 157a is slided relative to one another more than a length in abutting direction in the state of a high contact Distance, so as to obtain good wiping effect, and can effectively remove dust, dust and dirt and the other impurities of surface attachment. Thus contact resistance between the first terminal 51 and Second terminal 151 reduces, and makes between the first terminal 51 and Second terminal 151 Electrical connection is securely maintained.

Due to the width of edge part 157a（That is the second connector 101 size in the longitudinal direction）It is very narrow and small, contact Sliding contact area between the top 57a and edge part 157a in portion 57 reduces.In wiping process, contact is therefore very Height, so as to obtain good wiping effect.

Pressed towards the width center of the second pedestal 111 by the edge part 157a that the top 57a of contact site 57 presses In contact site 157 and deform contact site 157.This pressure and deformation are from contact site 157 via the rearward electric wire of connecting portion 156 Rear electric wire grasping foot 155r transmission near the contact site 157 of grasping part 153r, so as to grasp foot towards rear electric wire 155r to rear electric wire grasping foot 155r and making rear electric wire grasping foot 155r deformations to applying pressure to.The core of electric wire 191 Thus line is effectively grasped on both sides by rear electric wire grasping foot 155r, so as to more reliably maintain to grasp with rear electric wire The electrical connection of foot 155r.When contact site 157 deforms and edge part 157a and terminal limit the side surface 118a of convex portion 118 substantially When concordant, 57 contact terminal of contact site limits the side surface 118a of convex portion 118, and thus contact site 157 will not be towards the second pedestal 111 width center further deforms, and rear electric wire grasping foot 155 will not enter towards rear electric wire grasping foot 155r One step deforms.Therefore, the heart yearn of electric wire 191 will not be grasped the excessive power grasping of foot 155r on both sides by rear electric wire, So as to the damage or disrumpent feelings for avoiding being caused by excessive power.

When the body 113 of the second pedestal 111 enters the docking space 13 of the first pedestal 11, the second pedestal 111 is constituted The second sticking department the second front sticking department 116f and the second rear sticking department 116r with constitute the first pedestal 11 first lock Determine the first front sticking department 16f and the first rear sticking department 16r engagements in portion.When the second front sticking department 116f and the second rear When sticking department 116r is engaged with the first front sticking department 16f and the first rear sticking department 16r, the second pedestal 111 and the first pedestal 11 elastic deformations at least in part, so that locking in front of the second front sticking department 116f and the second rear sticking department 116r and first Determine portion 16f and the first rear sticking department 16r relative resilient deformations.

As described above, when engaging with the second rear sticking department 116r, a preloading one with latch-release direction phase The first rear sticking department 16r is put on anti-direction, so as to improving rigidity and preventing elastic deformation.Therefore, compared to second Situation when front sticking department 116f is engaged with the first front sticking department 16f, when the second rear sticking department 116r and the first rear When sticking department 16r is engaged, operator must apply bigger power.On the other hand（conversely）, when the second rear sticking department When 116r is engaged with the first rear sticking department 16r, operator runs into bigger resistance, and the resistance causes a perceptible click Sound.This docking for allowing an operator to discover exactly the first connector 1 and the second connector 101 is completed.

When the docking of the first connector 1 and the second connector 101 is completed, the body 113 of the second pedestal 111 is contained in The docking space 13 of the first pedestal 11, most of upper surface of the sidepiece 12 of the first pedestal 11 is by the top plate portion of the second pedestal 111 114 cover, and the front surface of the sidepiece 12 of the first pedestal 11 is substantially concordant with the body 113 of the second pedestal 111.Docking space 13 part in front of to base plate 14 is made up of front space 13f, thus near the second base of the front end of body 113 Surface of the lower surface of seat 111 towards the substrate 91 across front space 13f.That is, front space 13f is defined being located at Near body 113（Including at least antetheca 121c）Front end the lower surface of the second pedestal 111 and the surface of substrate 91 between A space.

When the first connector 1 and the docking of the second connector 101 are completed, the first pedestal 11 and the second pedestal 111 pass through The engagement of a pair first front sticking department 16f of the left and right sides and a pair of the left and right sides of the second front sticking department 116f and A pair first rear sticking department 16r of the left and right sides are locked with the engagement of a pair second rear sticking department 116r of the left and right sides It is in place.That is, described two connectors are on two positions of the left and right sides towards front end and towards a left side for rear end On two positions of right both sides（On the total of four position of first and second sticking department）Locked by first and second sticking department.From And prevent the docking between the first connector 1 and the second connector 101 to be unexpectedly released from.
