Pair of locking sheet accommodation section 29 is formed on inner sides Width both ends, sidewall 20A that are positioned at cloudy side body 20.Specifically, locking plate accommodation section 29 is formed at respectively between terminal accommodation section 22 and the two side 20A of cloudy side body 20, forms along the form of the side of cloudy side body 20.And accommodation section, 29Yu anti-delinking part, locking plate accommodation section 28 similarly, forms the form caving in upward from the bottom surface of cloudy side body 20.
As shown in Figure 1 and Figure 4, the inner surface that is terminal accommodation section 22 sides in the Width inner side of locking plate accommodation section 29 is formed with respectively: interim engaging projection (example of " sticking department " of the present invention) 30, remains on temporary card allocation by aftermentioned retainer 40; And formal engaging projection (example of " sticking department " of the present invention) 31, retainer 40 is remained on to formal catch positions.Interim engaging projection 30 and formal engaging projection 31 all from the inner surface of terminal accommodation section 22 sides towards Width outside outstanding formation, and form along the form of fore-and-aft direction extension.
Formal engaging projection 31 is positioned at than interim engaging projection 30 by the i.e. position of top, the inboard of locking plate accommodation section 29, and forms the section essentially rectangular shape on top with the formal engaging face 31A extending from the inner surface broad ways of terminal accommodation section 22 sides.
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 explanation of retainer 40, it is benchmark that so-called fore-and-aft direction be take the direction of arrow of Fig. 5, and front side is labeled as to F, and rear side is labeled as to R.
As shown in Figure 7, anti-delinking part 41 forms roughly U-shaped of backsight visual angle, forms the terminal inserting hole 43 of a plurality of essentially rectangular shapes that connect along fore-and-aft direction on above-below direction and Width, thereby forms horizontal longer clathrate on Width.
Upper surface in bottom surface and the anti-delinking part 41 of each terminal inserting hole 43, is formed with a plurality of terminal engaging portions 44 accordingly with each cavity 23, and described terminal engaging portion 44 is from rear and connecting portion 25 engagings that are inserted into the cloudy type terminal 24 in the cavity 23 of cloudy side body 20.
And, anti-delinking part 41 by terminal engaging portion 44 is projected in cavity 23 from rear by cloudy type terminal 24 engagings, cloudy type 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 be cloudy type terminal 24 in the position of cavity 23 interior anticreeps, described temporary card allocation is that terminal engaging portion 44 is kept out of the way and allows that cloudy type terminal 24 is with respect to the position of the plug of cavity 23 in cavity 23.Thus, as shown in Figure 8, at cloudy type terminal 24, be contained under the state in cavity 23, when anti-delinking part 41 is fitted to formal catch positions, by terminal engaging portion 44 from rear by 25 engagings of the connecting portion of cloudy type terminal 24, and utilize protuberance 26 and terminal engaging portion 44 by the dual engaging of cloudy type terminal 24.
As shown in Figure 5 and Figure 6, pair of locking plate 42 forms tabulars, and 41 rear is adjacent to form in anti-delinking part.And lockplate 42 is configured to be possessed: matrix 45, from anti-delinking part, rearward extend at 41 Width both ends; And locking plate 46, from matrix 45, erect upward.In addition, in Fig. 5, take paper left nearby side be rear, the right-hand inboard of the paper of take is the place ahead.
The upper ora terminalis of locking plate 46 be formed with can with locking plate accommodation section 29 in interim engaging projection 30 and the lock pawl 48 of formal engaging projection 31 engagings.It is side-prominent in Width that lock pawl 48 forms from locking plate 46 ora terminalis, when anti-delinking part 41 is disposed at temporary card allocation, the lower surface of lock pawl 48 locks side engaging face 48A interim engaging face 30A engaging with interim engaging projection 30 from top, thereby anti-delinking part 41 can be remained on to temporary card allocation.And, when anti-delinking part 41 is disposed at formal catch positions, locking side engaging face 48A formal engaging face 31A engaging with formal engaging projection 31 from top, thus anti-delinking part 41 can be remained on to formal catch positions.
And lock pawl 48 forms the form of extending along fore-and-aft 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 engaging projection 31 with interim engaging projection 30.Thus, in temporary card allocation and formal catch positions, by making to lock side engaging face 48A and interim engaging face 30A and main card, determine face 31A and spread all over fore-and-aft direction ground and contact, anti-delinking part 41 can be remained on effectively to temporary card allocation and formal catch positions.
And the side edge part adjacent with anti-delinking part 41 in locking plate 46 is formed with to side-prominent rib 49 in Width.Rib 49 forms with lock pawl 48, suppresses locking plate 46 and is accompanied by strain and fatigue.
On the other hand, at the two side of cloudy side body 20 20A, be formed with respectively the through hole 32 of longitudinal longer essentially rectangular shape on fore-and-aft direction.Through hole 32 connects sidewall 20A and forms in the above-below direction substantial middle portion broad ways of the sidewall 20A of cloudy side body 20.And, through hole 32 be configured in can be by this through hole 32 position from the periphery of the interim engaging projection 30 of Visual Confirmation outside Width and formal engaging projection 31.Thus, in anti-delinking part 41, be maintained under the state of temporary card allocation, can pass through the upper end of through hole 32 Visual Confirmation locking plates 46, in anti-delinking part 41, be maintained under the state of formal catch positions, can pass through the part of the top side of ratio base end part of through hole 32 Visual Confirmation locking plates 46.
; no matter at temporary card allocation or in formal catch positions in the situation that; the base end part of matrix 45 and locking plate 46 is all positioned at than through hole 32 state of the inner side of the sidewall 20A of the position of side on the lower in being configured in, and can suppress miscellaneous part and contact with the base end part of matrix 45 or locking plate 46.Thus, compare with the situation that locking plate 46 exposes completely in Width outside, can suppress to make because of the contact of miscellaneous part the situation that locking plate 46 is damaged or be out of shape.
And the adjacent sidewall 20A on above-below direction of through hole 32 is that fore-and-aft direction forms continuously in the chimeric direction of cloudy side body 20.; at the upper and lower sidewall 20A that is positioned at through hole 32, there is no step difference; even in the chimeric posture of cloudy side body 20 in the situation that make 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 not can with the sidewall 20A hook of cloudy side body 20, can carry out swimmingly chimeric operation.
And, the curved space when inner space of through hole 32 forms locking plate 46 strain.Thus, the process moving to formal catch positions from temporary card allocation in anti-delinking part 41, lock pawl 48 slides in formal engaging projection 31, locking plate 46 is out of shape to Width outer elastic, thereby can allow that the terminal part of locking plate 46 enters the inner space of through hole 32 (curved space).And, when lock pawl 48 is crossed formal engaging projection 31, locking plate 46 elastic recoveries, the locking side engaging face 48A of lock pawl 48 and the formally formal engaging face 31A engaging of engaging projection 31, thus make retainer 41 be maintained at formal catch positions.
; the terminal part of locking plate 46 is contained in to the inner space (curved space) of through hole 32; thereby needn't between the sidewall 20A of cloudy side body 20 and locking plate accommodation section 29, the wider curved space of Width be set, just can make locking plate 46 strains.Thus, compare with the situation of the curved space at the interior independent formation locking plate 46 of cloudy side body 20, can prevent that cloudy side body 20 from maximizing.
And when lock pawl 48 slides and locking plate 46 while starting to be out of shape to Width outer elastic in formal engaging projection 31, locking plate 46 becomes the state with the sidewall 20A butt of the downside that is positioned at through hole 32 (adjacent with the downside of through hole 32).And, when locking plate 46 further strain, the state that the sidewall 20A that becomes the downside that is positioned at through hole 32 presses and supports the outer surface of the base end part of locking plate 46 in Width inner side.Thus, the required insertion force of locking plate 46 strains is adjusted into predetermined size, can suppress because of locking plate 46 unexpectedly strain retainer 40 is moved between temporary card allocation and formal catch positions.And, can suppress the situation of locking plate 46 fatigues.
Present embodiment is structure as above, next, the assemble method of connector 10 is described simply, and its action effect is described.
First, make retainer 40 be embedded in retainer installing hole 27 from the below of cloudy side body 20, retainer 40 is moved upward with respect to cloudy side body 20.In this process, the lock pawl 48 of locking plate 46 slides in interim engaging projection 30, and locking plate 46 be take the base end part of this locking plate 46 and is out of shape as fulcrum to Width outer elastic.Now, locking plate 46 forms the form that erects upward from the upper limb of matrix 45 and by slit 47 state separated with anti-delinking part 41, therefore can make locking plate 46 not with the anti-delinking part 41 ground strains that interact.
That is, form with anti-delinking part with locking plate and locking plate is rearward expanded and the situation of strain is compared, can prevent that locking plate 46 from tilting and strain to the different direction of the direction from correct.And, can mutually wear and tear with interim engaging projection 30 by making locking plate 46 tilt to suppress locking plate 46, therefore can make locking plate 46 in stable condition with the engaging of interim engaging projection 30.
Then, as shown in Figure 4, when the lock pawl 48 sliding in interim engaging projection 30 is crossed interim engaging projection 30, from below, the locking side engaging face 48A to lock pawl 48 carries out engaging to the interim engaging face 30A by interim engaging projection 30, and anti-delinking part 41 is maintained at temporary card allocation.And as shown in Figure 3, under this state, the terminal engaging portion 44 of anti-delinking part 41 is kept out of the way in cavity 23, cloudy type terminal 24 can be plugged with respect to cavity 23.
Then, the cloudy type terminal 24 that the end with electric wire W is connected makes cloudy type terminal 24 be inserted into correct position in inserting cavity 23 from rear, thereby prevents that by protuberance 26 cloudy type terminal 24 from deviating from cavity 23.
After preventing that in each cavity 23 cloudy type terminal 24 from deviating from, retainer 40 is further moved upward with respect to cloudy side body 20.In this process, the lock pawl 48 of locking plate 46 slides in formal engaging projection 31, and locking plate 46 be take the base end part of this locking plate 46 and is out of shape as fulcrum 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, thereby allows that locking plate 46 is out of shape to Width outer elastic.And, to the locking plate 46 of Width outer elastic distortion, become the state that the sidewall 20A of the downside that is positioned at through hole 32 presses and supports to Width inner side, thereby can suppress unexpectedly strain of locking plate 46, and can suppress the situation of locking plate 46 fatigues.
And, at the lock pawl 48 of locking plate 46, in interim engaging projection 30, slide and during locking plate 46 strain, with the situation of interim engaging projection 30 similarly, also can suppress locking plate 46 to the different direction strain of the direction from correct.
Then, when the lock pawl 48 of locking plate 46 is crossed formal engaging projection 31, as shown in Figure 9, from below, the locking side engaging face 48A to lock pawl 48 carries out engaging to the formal engaging face 31A by formal engaging projection 31, as shown in Figure 8, anti-delinking part 41 is maintained at formal catch positions.And, as shown in Figure 8, under this state, the terminal engaging portion 44 of anti-delinking part 41 to cavity 23 interior outstanding and from rear by 25 engagings of the connecting portion of cloudy type terminal 24, prevent that cloudy type terminal 24 from deviating from cavity 23.Thus, by protuberance 26 and 44 pairs of cloudy type terminals 24 of terminal engaging portion, carry out dual engaging.
As mentioned above; according to present embodiment; the base end part of the matrix in lockplate 42 45 and locking plate 46 is contained in locking plate accommodation section 29; thereby the sidewall 20A by cloudy side body 20 protects not to be subject to miscellaneous part to affect, can suppress that miscellaneous part contacts with the base end part of locking plate 46 and the situation that makes the damaged or distortion of locking plate 46.
And, by the sidewall 20A formation through hole 32 of the cloudy side body 20 at protection lock stator 46, allow locking plate 46 strains, compare with the situation that forms separately the curved space of locking plate 46 in cloudy side body, can prevent that cloudy side body 20 from maximizing.
And then, according to present embodiment, the sidewall 20A that makes to be positioned at the upper and lower cloudy side body 20 of through hole 32 is to form continuously on fore-and-aft direction in the chimeric 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 not can with cloudy side body 20 hooks, can make chimeric operation carry out swimmingly.
< execution mode 2>
Next, with reference to Figure 11 and Figure 12, embodiments of the present invention 2 are described.
Execution mode 2 obtains the alteration of form of the locking plate of the retainer in execution mode 1 40 46, and due to structure, the effect repetition common with above-mentioned execution mode, therefore the description thereof will be omitted.And, for the identical label of the structure tag identical with above-mentioned execution mode.
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 is extended in outside from locking plate 146 to Width, and form along with extending and the form of approach locking sheet 146 upward from the end in its outside, and under remaining on the state of cloudy side body 20, retainer 140 is contained in the through hole 32 of cloudy side body 20.And 41 while being disposed at temporary card allocation in anti-delinking part, the face of the downside of anticreep projection 150 can with the open lower side edge engaging of through hole 32.; the interim engaging face 30A by interim engaging projection 30 from below when the locking side engaging face 148A of the lock pawl 148 of locking plate 146 is carried out to engaging; the open lower side edge of through hole 32, from the face engaging of the downside of below and anticreep projection 150, is deviating from direction by dual engaging retainer 140.Thus, when retainer 140 being moved because of maintenance etc. from formal catch positions to temporary card allocation, even in the situation that retainer 40 is applied to larger power along deviating from direction, lock pawl 148 and anticreep projection 150 these two position locking plates 46 also by from below engaging, thereby can suppress retainer 140, take advantage of other's power to deviate from from cloudy side body 20.Thus, compare with the situation that does not form anticreep projection 150 on locking plate, can suppress retainer 140 and come off from cloudy side body 20.
