As shown in Figure 3 and Figure 4, the width terminal accommodation portion 22 slightly narrower than the width dimensions of cloudy side body 20 is formed in the inside of cloudy side body 20.Terminal accommodation portion 22 has the cavity 23 of multiple form through along the longitudinal direction.As shown in Figure 4, above-below direction and Width are formed with multiple cavity 23, as shown in Figure 3, in cavity 23, the female terminal 24 be connected with the end of electric wire W can be held from rear.
The front portion of female terminal 24 becomes the connecting portion 25 of rib tubular, and rear portion is crimped on the end of electric wire W.Female terminal 24 is by making connecting portion 25 locking and prevent female terminal 24 from deviating from cavity 23 from rear in the protuberance 26 that extends in cantilever manner toward the front by the inwall from cavity 23.
Further, when cloudy side body 20 and positive side body are correctly chimeric, the not shown convex terminal remained in the accommodation section of positive side body enters in the connecting portion 25 of female terminal 24, thus makes female terminal 24 and convex terminal can the mode of conducting be connected.
As shown in Figures 2 and 3, retainer installing hole 27 is formed with in the fore-and-aft direction substantially central portion of the bottom surface of cloudy side body 20.The peristome of retainer installing hole 27 is formed as roughly U-shaped, retainer installing hole 27 by the direction of the width laterally longer accommodation section, anti-delinking part 28 and rearward extend from the both ends of accommodation section, anti-delinking part 28 in the longitudinal direction longitudinally longer pair of locking sheet accommodation section 29 form.
As shown in Figure 3, accommodation section, anti-delinking part 28 is formed as the form caved in upward from the bottom surface of cloudy side body 20, and the inner space of accommodation section, anti-delinking part 28 is communicated with each cavity 23 in terminal accommodation portion 22.
Pair of locking sheet accommodation section 29 is formed in inner side that be positioned at the Width both ends of cloudy side body 20, sidewall 20A.Specifically, locking plate accommodation section 29 is formed between the two side 20A of terminal accommodation portion 22 and cloudy side body 20 respectively, is formed as the form of the side along cloudy side body 20.Further, locking plate accommodation section 29, in the same manner as accommodation section, anti-delinking part 28, is formed as the form caved in upward from the bottom surface of cloudy side body 20.
As shown in Figure 1 and Figure 4, inside the Width of locking plate accommodation section 29, namely the inner surface of terminal accommodation portion 22 side is formed respectively: interim locking projection (example of " sticking department " of the present invention) 30, remains on temporary card allocation by aftermentioned retainer 40; And formal locking projection (example of " sticking department " of the present invention) 31, retainer 40 is remained on formal catch positions.Interim locking projection 30 and formal locking projection 31 all from the inner surface of terminal accommodation portion 22 side towards Width protruding outside formed, and be formed as the form that extends along the longitudinal direction.
Interim locking projection 30 has the temporarily locking 30A extended outside Width from the inner surface of terminal accommodation portion 22 side on top, it is formed as the form along with extending near terminal accommodation portion 22 side after the outboard end of locking 30A temporarily extends slightly toward below downwards.
Formal locking projection 31 is positioned at than the inboard i.e. position of top of interim locking projection 30 by locking plate accommodation section 29, and is formed as the section rectangular shape on top with the formally locking 31A extended from the inner surface broad ways of terminal accommodation portion 22 side.
On the other hand, retainer 40 is configured to be possessed: anti-delinking part 41, can be fitted in accommodation section, anti-delinking part 28; And pair of locking plate 42, can be fitted to respectively in pair of locking sheet accommodation section 29.In addition, in the structure of retainer 40 illustrates, front side for benchmark, is labeled as F with the direction of arrow of Fig. 5 by so-called fore-and-aft direction, and rear side is labeled as R.
As shown in Figure 7, anti-delinking part 41 forms backsight visual angle roughly U-shaped, and above-below direction and Width are formed the terminal inserting hole 43 of multiple rectangular shape through along the longitudinal direction, thus is formed as clathrate laterally longer in the direction of the width.
At the bottom surface of each terminal inserting hole 43 and the upper surface of anti-delinking part 41, be formed with multiple terminal engaging portion 44 accordingly with each cavity 23, described terminal engaging portion 44 is locking with the connecting portion 25 being inserted into the female terminal 24 in the cavity 23 of cloudy side body 20 from rear.
And, anti-delinking part 41 is projected in cavity 23 from rear by locking for female terminal 24 by making terminal engaging portion 44, female terminal 24 can be moved between formal catch positions (with reference to Fig. 8) and temporary card allocation (with reference to Fig. 3), described formal catch positions is the position of female terminal 24 anticreep in cavity 23, and described temporary card allocation is that terminal engaging portion 44 is kept out of the way and allows the position of female terminal 24 relative to the plug of cavity 23 in cavity 23.Thus, as shown in Figure 8, under the state that female terminal 24 is contained in cavity 23, when anti-delinking part 41 is fitted to formal catch positions, by terminal engaging portion 44 from rear by locking for the connecting portion 25 of female terminal 24, and utilize protuberance 26 and terminal engaging portion 44 by dual for female terminal 24 locking.
As shown in Figure 5 and Figure 6, pair of locking plate 42 forms tabular, and is adjacent at the rear of anti-delinking part 41 be formed.And lockplate 42 is configured to be possessed: matrix 45, rearward extend from the Width both ends of anti-delinking part 41; And locking plate 46, erect upward from matrix 45.In addition, in Figure 5, with paper left, nearby side is for rear, inboard for front with paper right.
Matrix 45 is all formed as rectangular flat shape, and it is integrally formed in the rearward end of anti-delinking part 41 under form respect to one another.
Locking plate 46 is formed as the rectangular flat shape thinner than the plate thickness of matrix 45.Locking plate 46 is integrally formed in outside the Width of the upper edge of matrix 45, and can with the base end part be connected with matrix 45 for fulcrum is out of shape to Width outer elastic.And be formed with the slit 47 of downward-extension in the position that locking plate 46 is adjacent with anti-delinking part 41, locking plate 46 is in anti-delinking part 41 state be separated.Thus, locking plate 46 can not interact with anti-delinking part 41, can make locking plate 46 strain independently.
The upper edge of locking plate 46 be formed can with the interim locking projection 30 in locking plate accommodation section 29 and the locking lock pawl 48 of formal locking projection 31.Lock pawl 48 is formed as outstanding inside Width from the upper edge of locking plate 46, when anti-delinking part 41 is configured at temporary card allocation, the lower surface of lock pawl 48 and lock side locking 48A locking from a temporarily locking 30A of top and interim locking projection 30, thus anti-delinking part 41 can be remained on temporary card allocation.And when anti-delinking part 41 is configured at formal catch positions, lock side locking 48A is locking from a formally locking 31A of top and formal locking projection 31, thus anti-delinking part 41 can be remained on formal catch positions.
And lock pawl 48 is formed as the form extended along the longitudinal direction, the length dimension of the fore-and-aft direction of lock pawl 48 is set to the size roughly the same with the length dimension of the fore-and-aft direction of formal locking projection 31 with interim locking projection 30.Thus, in temporary card allocation and formal catch positions, by making lock side locking 48A and locking 30A and main card temporarily determine face 31A throughout fore-and-aft direction earth surface, anti-delinking part 41 can be remained on temporary card allocation and formal catch positions effectively.
And the side edge part adjacent with anti-delinking part 41 in locking plate 46 is formed with rib 49 outstanding inside Width.Rib 49 and lock pawl 48 form, and suppress locking plate 46 tired along with strain.
On the other hand, the through hole 32 of rectangular shape longitudinally longer is in the longitudinal direction formed respectively at the two side 20A of cloudy side body 20.Through hole 32 the sidewall 20A of cloudy side body 20 the through sidewall 20A of above-below direction substantially central portion broad ways and formed.And through hole 32 is configured in can by the position of periphery of this through hole 32 the outside interim locking projection 30 of visual confirmation and formal locking projection 31 in the width direction.Thus, under the state that anti-delinking part 41 is maintained at temporary card allocation, can by the upper end of the visual confirmation locking plate 46 of through hole 32, under the state that anti-delinking part 41 is maintained at formal catch positions, can by the part of the side top ratio base end part of through hole 32 visual confirmation locking plate 46.
Namely, when no matter being at temporary card allocation or in formal catch positions, the base end part of matrix 45 and locking plate 46 is all in the state of the inner side being configured in the sidewall 20A be positioned at than through hole 32 position on the lower, and miscellaneous part can be suppressed to contact with the base end part of matrix 45 or locking plate 46.Thus, compared with situation about exposing completely outside Width with locking plate 46, can suppress to make the situation that locking plate 46 is damaged or be out of shape because of the contact of miscellaneous part.
And the sidewall 20A adjacent in the vertical direction of through hole 32 is formed continuously in the chimeric direction of cloudy side body 20 and fore-and-aft direction.Namely, step difference is not had at the upper and lower sidewall 20A being positioned at through hole 32, even when the chimeric posture of cloudy side body 20 makes cloudy side body 20 be fitted in the accommodation section of positive side body under the state that Width tilts a little, the opening edge of accommodation section also can not with the sidewall 20A hook of cloudy side body 20, chimeric operation can be carried out swimmingly.
And the inner space of through hole 32 is formed as curved space during locking plate 46 strain.Thus, anti-delinking part 41 is from temporary card allocation to the process of formal catch positions movement, lock pawl 48 slides in formal locking projection 31, locking plate 46 to the distortion of Width outer elastic, thus can allow that the terminal part of locking plate 46 enters the inner space (curved space) of through hole 32.Further, when lock pawl 48 crosses formal locking projection 31, locking plate 46 elastic recovery, lock side locking 48A of lock pawl 48 an and formally locking 31A of formal locking projection 31 is locking, thus makes retainer 41 be maintained at formal catch positions.
Namely, the terminal part of locking plate 46 is contained in the inner space (curved space) of through hole 32, thus the wider curved space of Width need not be set between the sidewall 20A of cloudy side body 20 and locking plate accommodation section 29, just can make locking plate 46 strain.Thus, with compared with forming separately the situation of the curved space of locking plate 46 in cloudy side body 20, can prevent cloudy side body 20 from maximizing.
And when when lock pawl 48 slides in formal locking projection 31, locking plate 46 starts to be out of shape to Width outer elastic, locking plate 46 becomes the state abutted with the sidewall 20A of the downside being positioned at through hole 32 (adjacent with the downside of through hole 32).Further, when the further strain of locking plate 46, the sidewall 20A becoming the downside being positioned at through hole 32 presses and the state supported the outer surface of the base end part of locking plate 46 inside Width.Thus, the insertion force needed for locking plate 46 strain is adjusted to predetermined size, can suppresses because of locking plate 46 unexpectedly strain and make retainer 40 move between temporary card allocation and formal catch positions.And, the situation of locking plate 46 fatigue can be suppressed.
Present embodiment is structure as above, next, is described simply the assemble method of connector 10, and is described its action effect.
First, make retainer 40 be embedded in retainer installing hole 27 from the below of cloudy side body 20, retainer 40 is moved upward relative to cloudy side body 20.In this process, the lock pawl 48 of locking plate 46 slides in interim locking projection 30, locking plate 46 with the base end part of this locking plate 46 for fulcrum is out of shape to Width outer elastic.Now, locking plate 46 is formed as the form erected upward from the upper limb of matrix 45 and the state be separated with anti-delinking part 41 by slit 47, therefore, it is possible to make locking plate 46 do not interact with anti-delinking part 41 ground strain.
That is, form with anti-delinking part with locking plate and locking plate rearward expand and strain situation compared with, can prevent locking plate 46 from tilting and strain to the direction different from correct direction.And, can tilt suppress locking plate 46 and interim locking projection 30 mutually to wear and tear by making locking plate 46, therefore, it is possible to make the locking in stable condition of locking plate 46 and interim locking projection 30.
Then, as shown in Figure 4, when the lock pawl 48 slided in interim locking projection 30 crosses interim locking projection 30, carry out locking to the lock side of lock pawl 48 locking 48A from below by a temporarily locking 30A of interim locking projection 30, anti-delinking part 41 is maintained at temporary card allocation.And as shown in Figure 3, in this condition, the terminal engaging portion 44 of anti-delinking part 41 is kept out of the way in cavity 23, female terminal 24 can be plugged relative to cavity 23.
Then, the female terminal 24 be connected is inserted in cavity 23 from rear, make female terminal 24 be inserted into correct position, thus prevent female terminal 24 from deviating from cavity 23 by protuberance 26 with the end of electric wire W.
After preventing female terminal 24 from deviating from each cavity 23, retainer 40 is moved upward further relative to cloudy side body 20.In this process, the lock pawl 48 of locking plate 46 slides in formal locking projection 31, locking plate 46 with the base end part of this locking plate 46 for fulcrum is out of shape to Width outer elastic.Now, as shown in Figure 10, the terminal part of locking plate 46 is contained in the inner space of the through hole 32 of cloudy side body 20, thus allows that locking plate 46 is out of shape to Width outer elastic.And, locking plate 46 to the distortion of Width outer elastic becomes and is pressed inside Width and the state supported by the sidewall 20A of the downside being positioned at through hole 32, thus locking plate 46 unexpectedly strain can be suppressed, and the situation of locking plate 46 fatigue can be suppressed.
And, the lock pawl 48 of locking plate 46 slide in interim locking projection 30 and locking plate 46 strain time, in the same manner as the situation of interim locking projection 30, locking plate 46 also can be suppressed to the direction strain different from correct direction.
Then, when the lock pawl 48 of locking plate 46 crosses formal locking projection 31, as shown in Figure 9, carry out locking to the lock side of lock pawl 48 locking 48A from below by a formally locking 31A of formal locking projection 31, as shown in Figure 8, anti-delinking part 41 is maintained at formal catch positions.And as shown in Figure 8, in this condition, the terminal engaging portion 44 of anti-delinking part 41 is outstanding and from rear by locking for the connecting portion 25 of female terminal 24, prevent female terminal 24 from deviating from cavity 23 in cavity 23.Thus, undertaken dual locking by protuberance 26 and terminal engaging portion 44 pairs of female terminals 24.
As mentioned above; according to the present embodiment; the base end part of the matrix 45 in lockplate 42 and locking plate 46 is contained in locking plate accommodation section 29; thus undertaken protecting not affect by miscellaneous part by the sidewall 20A of cloudy side body 20, miscellaneous part can be suppressed to contact with the base end part of locking plate 46 and make the situation that locking plate 46 is damaged or be out of shape.
And, form through hole 32 by the sidewall 20A of the cloudy side body 20 at protection lock stator 46, allow locking plate 46 strain, with compared with forming separately the situation of the curved space of locking plate 46 in cloudy side body, can prevent cloudy side body 20 from maximizing.
And then, according to the present embodiment, the sidewall 20A of the upper and lower cloudy side body 20 being positioned at through hole 32 is formed continuously on the chimeric direction and fore-and-aft direction of cloudy side body 20, therefore when cloudy side body 20 is fitted in the accommodation section of positive side body, the opening edge of accommodation section can not with cloudy side body 20 hook, chimeric operation can be made to carry out swimmingly.
< execution mode 2>
Next, with reference to Figure 11 and Figure 12, embodiments of the present invention 2 are described.
The alteration of form of the locking plate 46 of the retainer 40 in execution mode 1 obtains by execution mode 2, and because the structure common with above-mentioned execution mode, effect repeat, therefore the description thereof will be omitted.Further, for the label that the structure tag identical with above-mentioned execution mode is identical.
The retainer 140 of execution mode 2 is formed with anticreep projection 150 at the Width lateral surface of the locking plate 146 of lockplate 142.Anticreep projection 150 extends outside Width from locking plate 146, and be formed as along with the end outside it extends and the form of approach locking sheet 146 upward, and be contained in the through hole 32 of cloudy side body 20 under the state that retainer 140 remains on cloudy side body 20.And when anti-delinking part 41 is configured at temporary card allocation, the face of the downside of anticreep projection 150 can be locking with the open lower side edge of through hole 32.Namely, when the temporarily locking 30A by interim locking projection 30 carries out locking to lock side locking 148A of the lock pawl 148 of locking plate 146 from below, the open lower side edge of through hole 32 is locking with the face of the downside of anticreep projection 150 from below, and retainer 140 is being deviate from direction by dual locking.Thus, when making retainer 140 move from formal catch positions to temporary card allocation because maintenance waits, even when along deviate from direction larger power is applied to retainer 40, at lock pawl 148 and these two position locking plates 46 of anticreep projection 150 also by locking from below, thus retainer 140 can be suppressed to take advantage of other's power to deviate from from cloudy side body 20.Thus, with do not form the situation of anticreep projection 150 on locking plate compared with, retainer 140 can be suppressed to come off from cloudy side body 20.
Other execution modes of < >
The present invention is not limited to the execution mode illustrated according to above-mentioned record and accompanying drawing, and such as following execution mode is also included in the technical scope of the present invention.
(1) in the above-described embodiment, be configured to lockplate 42 adjacent with the rear of anti-delinking part 41, but the present invention is not limited to such mode, also can be such as form sticking department in the front of anti-delinking part 41, can also be form sticking department outside the Width of anti-delinking part.
