Accommodation portion, anti-delinking part 24 constitutes the form caved in upward in the bottom surface from connector shell 20, and the inner space in accommodation portion, anti-delinking part 24 connects with each cavity 21 of connector shell 20.
Accommodation portion of pair of locking portion 25 is formed at the inner side of the sidewall 20A at the width both ends of connector shell 20.Specifically, as shown in Figure 4 and Figure 8, sticking department accommodation portion 25 is respectively formed between the cavity 21 and the two side 20A of connector shell 20 at width both ends, and is formed along the form of the side of connector shell 20.And, in the same manner as accommodation portion, anti-delinking part 24, sticking department accommodation portion 25 constitutes the form recessed upward from the bottom surface of connector shell 20.
On the other hand, keeper 40 is configured to possess: anti-delinking part 41, it is possible to be fitted in accommodation portion, anti-delinking part 24；And pair of locking portion 42, it is possible to it is fitted to respectively in accommodation portion of pair of locking portion 25.It addition, in the structure of keeper 40 illustrates, front side, with the direction of arrow of Fig. 9 for benchmark, is labeled as F by fore-and-aft direction, and rear side is labeled as B.
As shown in Figures 9 to 11, anti-delinking part 41 constitutes backsight visual angle and is a substantially U-shaped, and on above-below direction and width, form the terminal inserting hole 43 of multiple rectangular shape through along the longitudinal direction, thus be formed as clathrate laterally longer in the direction of the width.
Female terminal can be inserted through terminal inserting hole 43 along the longitudinal direction, on the bottom surface of each terminal inserting hole 43 and the upper surface of anti-delinking part 41, being correspondingly formed multiple terminal engaging portion 44 with each cavity 21, described terminal engaging portion 44 is locking with the female terminal in the cavity 21 being inserted into connector shell 20 from rear.
And, anti-delinking part 41 is projected in cavity 21 from rear by locking for female terminal by terminal engaging portion 44, female terminal can be moved between formal catch positions (with reference to Fig. 6 and Fig. 7) and temporary card allocation (with reference to Fig. 4), described formal catch positions is the position preventing female terminal from deviating from cavity 21, and temporary card allocation is that terminal engaging portion 44 is kept out of the way in cavity 21 and allowed the position that female terminal inserts to cavity 21 or extracts from cavity 21.Thus, when female terminal is contained in cavity 21, when anti-delinking part 41 is fitted together to formal catch positions, by terminal engaging portion 44 from rear by locking for female terminal, thus utilizing protuberance 22 and terminal engaging portion 44 by dual for female terminal locking.
And, as shown in Figure 3 and Figure 4, keeper 40 becomes the state that the part making anti-delinking part 41 and sticking department 42 highlights downwards from the bottom surface of connector shell 20 at temporary card allocation place, as shown in Figure 6 and Figure 7, keeper 40 is sentenced, in formal catch positions, the state that is completely accommodated in keeper installing hole 23 and is fitted together to, and the bottom surface of connector shell 20, the bottom surface of anti-delinking part 41 and the bottom surface of sticking department 42 become the state being on substantially the same face.
As shown in Figures 9 to 11, pair of locking portion 42 constitutes tabular, and the rear in anti-delinking part 41 is adjacent and is formed.And, sticking department 42 is configured to possess: base plate 45, rearward extends from the width both ends of anti-delinking part 41；And locking plate 46, erect upward from base plate 45.It addition, in fig .9, with nearby side, paper left for rear, inboard for front with paper right.
Base plate 45 all constitutes rectangular flat shape, and is integrally formed in the rearward end of anti-delinking part 41 under form relative to each other.
Locking plate 46 is formed as the rectangular flat shape thinner than base plate 45 thickness of slab.Locking plate 46 is integrally formed in outside the width of the upper end-face edge of base plate 45, and can deform to width outer elastic with the base end part being connected with base plate 45 for fulcrum.
On the other hand, it is respectively formed with the through hole 26 for making the locking plate 46 of elastic deformation keep out of the way at the two side 20A of connector shell 20.As it is shown in figure 1, through hole 26 constitutes rectangular shape longitudinally longer in the longitudinal direction, and, as shown in figs. 4 and 7, in the above-below direction substantially central portion of sidewall 20A by through in the width direction for sidewall 20A and formed.
The terminal part of locking plate 46 can enter the inner space of through hole 26, and the terminal part to the locking plate 46 of width outer elastic deformation enters into the inner space of through hole 26, thus allowing that locking plate 46 deforms to width outer elastic.
Further, as shown in Fig. 1, Fig. 4 and Fig. 7, inside the width in sticking department accommodation portion 25, namely two inwalls of cavity 21 side are respectively formed with: formal locking projection 27, and keeper 40 is maintained at formal catch positions；And interim locking projection 28, keeper 40 is maintained at temporary card allocation.
Formal locking projection 27 is protruding outside and formed from the inwall of cavity 21 side to width, and constitutes the form extended along the longitudinal direction.And, formal locking projection 27 constitutes section rectangular shape, and the upper surface of formal locking projection 27 is raised sides formally locking 27A.
In the same manner as formal locking projection 27, interim locking projection 28 is protruding outside and formed from the inwall of cavity 21 side to width, and constitutes the form extended along the longitudinal direction.And, interim locking projection 28 is more protruding outside and formed to width further than formal locking projection 27, it has a raised sides locking 28A temporarily extended from the inwall of cavity 21 side to width on top, and constitute extends slightly downwards from the outboard end of raised sides locking 28A temporarily after along with extension downwards close to the form of cavity 21 side.
And, interim locking projection 28 is arranged in the ratio formal locking projection 27 open side near sticking department accommodation portion 25 i.e. downside, and the length dimension of the fore-and-aft direction of interim locking projection 28 is set to roughly the same with the length dimension of the fore-and-aft direction of formal locking projection 27.And, interim locking projection 28 is formed at the fore-end near the region of rear side of the back-end location than formal locking projection 27, and the front position of interim locking projection 28 is arranged in the position overlapping in the vertical direction with the back-end location of formal locking projection 27.That is, formal locking projection 27 and interim locking projection 28 stagger on fore-and-aft direction and above-below direction and are formed.
On the other hand, as shown in Figure 9 and Figure 10, it is formed at the upper end-face edge of locking plate 46: interim locking pawl 47, it is possible to locking with interim locking projection 28；And formal locking pawl 48, it is possible to locking with formal locking projection 27.And, interim locking pawl 47 and formal locking pawl 48 are integrally formed in the longitudinal direction continuously.
Interim locking pawl 47 constitutes the form linearly extended from the rear end of locking plate 46 towards front, and is arranged in the fore-and-aft direction substantially central portion than locking plate 46 near rear side.And, interim locking pawl 47 is prominent from the upper end-face edge of locking plate 46 towards width and is formed, the face of the downside of interim locking pawl 47 namely temporarily locking 47A be formed as can be locking with the raised sides of interim locking projection 28 locking 28A temporarily.To be formed as interim locking the 28A than raised sides longer in the longitudinal direction for locking 47A temporarily, and is set as making locking at locking 47A and raised sides locking 28A temporarily temporarily that raised sides locking 28A temporarily is overall to be contacted with locking 47A face temporarily.
Formal locking pawl 48 is formed as the fore-and-aft direction substantially central portion than locking plate 46 near front side.And, formal locking pawl 48 constitutes the form that the front end from interim locking pawl 47 linearly extends to the front end of locking plate 46, and the length dimension of the fore-and-aft direction of formal locking pawl 48 is set to roughly the same with the length dimension of the fore-and-aft direction of interim locking pawl 47.
And, in the same manner as interim locking pawl 47, formal locking pawl 48 is prominent from the upper end-face edge of locking plate 46 to width and is formed, and the jag of formal locking pawl 48 is formed as being on the same face with the jag of interim locking pawl.
And, the lower surface of formal locking pawl 48 is can with the raised sides of a formal locking projection 27 formally locking formally locking 48A locking for 27A, and its temporarily locking 47A with interim locking pawl 47 is formed as being in the same face.And, formally locking 48A be formed as in the longitudinal direction than raised sides formal locking 27A longer, and it being set to when formally locking 27A is locking for formally locking 48A and raised sides so that raised sides formally locking 27A is overall to be contacted with formally locking 48A face.
When keeper 40 moves back and forth between temporary card allocation and formal catch positions, formal locking pawl 48 slides in formal locking projection 27.Thus, front side half part of the locking plate 46 being formed with formal locking pawl 48 makes formal locking pawl 48 cross formal locking raised 27 to the deformation of width outer elastic, so that locking plate 46 elastic recovery.Namely, locking plate 46 deforms to width outer elastic in the way of expanding to oblique front upper place, it is formed with rear side half part of locking plate 46 of interim locking pawl 47 almost without elastic deformation, and interim locking pawl 47 is less to the amount of width lateral displacement than formal locking pawl 48 to the amount of width lateral displacement.
And, anti-delinking part 41 is arranged in temporary card allocation, utilize raised sides locking 28A locking locking 47A temporarily from below temporarily, thus keeper 40 is maintained at temporary card allocation, anti-delinking part 41 is arranged in formal catch positions, utilize raised sides formally locking 27A locking formally locking 48A from below, thus keeper 40 is maintained at formal catch positions.
And, as shown in figs. 4 and 7, interim locking pawl 47 amount prominent to width from locking plate 46 is formed bigger from the amount that locking plate 46 is prominent than formal locking pawl 48, the length dimension blocking quantitative width when locking 28A is locking with a temporarily locking 47A of interim locking pawl 47 for the raised sides of the interim locking projection 28 in temporary card allocation place temporarily is set to, the length dimension of the width more quantitative than the card when formally locking 27A is locking with a formally locking 48A of formal locking pawl 48 for the raised sides of the formal locking projection 27 in formal catch positions place is big.Thus, raised sides locking 28A and locking area ratio raised sides locking for 47A formally locking 27A temporarily temporarily can be made with formally locking area locking for 48A is big such that it is able to the retentivity making the keeper 40 at temporary card allocation place is higher than the retentivity of the keeper 40 at formal catch positions place.
And, compared with the interim locking pawl 47 of the ratio in locking plate 46 part near base end part side, the formal locking pawl of ratio 48 in locking plate 46 part near base end part side is formed thicker, and the leading section of formal locking pawl 48 and reinforced wall 49 that is prominent from the front edge of locking plate 46 to width and that formed are integrally formed.That is, with between formal locking pawl 48 and interim locking pawl 47 for border, the rigidity of the part of the front side of locking plate 46 is higher than the rigidity of the part of rear side, it is possible to make locking plate 46 not easily deform to width outer elastic in formal catch positions.Thus, at the formal catch positions place that formal locking pawl 48 is quantitatively quantitatively little with the card of interim locking projection 28 than interim locking pawl 47 with the card of formal locking projection 27, it is possible to make the retentivity of keeper 40 improve.
Present embodiment is structure as above, then, the assemble method of adapter 10 is illustrated simply, and its action effect is illustrated.
First, make keeper 40 be embedded in keeper installing hole 23 from the lower section of connector shell 20, and make keeper 40 be moved upward relative to connector shell 20.In this process, the interim locking pawl 47 of locking plate 46 slides in interim locking projection 28, the rear section of locking plate 46 deforms to width outer elastic with the base end part of this locking plate 46 for fulcrum, so that locking plate 46 deforms to width outer elastic in the way of expanding to oblique back upper place.
Then, as shown in Figure 4, when interim locking projection 28 crossed by the interim locking pawl 47 slided in interim locking projection 28, a temporarily locking 47A of interim locking pawl 47 is locking from below by raised sides locking the 28A temporarily of interim locking projection 28, and keeper 40 is maintained at temporary card allocation.And, in this condition, the terminal engaging portion 44 of anti-delinking part 41 is kept out of the way in cavity 21, enables female terminal to plug relative to cavity 21.Then, female terminal being inserted in cavity 21 from rear, making female terminal be inserted into correct position, thus utilizing protuberance 22 to prevent female terminal from deviating from cavity 21.
Then, make keeper 40 mobile relative to connector shell 20 side further up.In this process, the formal locking pawl 48 of locking plate 46 slides in formal locking projection 27, the front part of locking plate 46 deforms to width outer elastic with the base end part of this locking plate 46 for fulcrum, and locking plate 46 deforms to width outer elastic in the way of expanding to oblique front upper place.Now, the terminal part of locking plate 46 enters into the inner space of the through hole 26 of connector shell 20, allows that locking plate 46 deforms to width outer elastic.
Then, as shown in Figure 7, when formal locking projection 27 crossed by the formal locking pawl 48 of locking plate 46, locking plate 46 elastic recovery, so that a formally locking 48A of formal locking pawl 48 is locking from below by raised sides formally locking the 27A of formal locking projection 27, keeper 41 is maintained at formal catch positions.And, in this condition, the terminal engaging portion 44 of anti-delinking part 41 is projected in cavity 21, and female terminal is locking from rear, it is prevented that female terminal is deviate from cavity 21.Thus, utilize protuberance 22 and terminal engaging portion 44 by dual for female terminal locking, complete adapter 10.
Then, the situation that keeper 40 moves from formal catch positions to temporary card allocation is made to illustrate to because maintenance waits.
When making keeper 40 move to temporary card allocation from formal catch positions, fixture etc. is inserted and moves between keeper installing hole 23 and keeper 40 and in the way of keeper 40 being pulled out downwards from keeper installing hole 23.Now, locking plate 46 becomes the state contrary with when moving from temporary card allocation to formal catch positions.That is, being slided in formal locking projection 27 by the formal locking pawl 48 of locking plate 46, make the front part of locking plate 46 deform to width outer elastic, locking plate 46 deforms to width outer elastic in the way of expanding to oblique front upper place.Then, as shown in Figure 4, when formal locking projection 27 crossed by the formal locking pawl 48 of locking plate 46, a temporarily locking 47A of interim locking pawl 47 is locking from below by raised sides locking the 28A temporarily of interim locking projection 28, and anti-delinking part 41 is maintained at temporary card allocation.Namely, slided in formal locking projection 27 by formal locking pawl 48, locking plate 46 is made to deform to width outer elastic with the direction expanded to oblique front upper place, but interim locking pawl 47 and interim locking projection 28 are formed at the rear side of locking plate 46, therefore the amount of bow of the rear side of locking plate 46 reduces, and becomes the state that interim locking pawl 47 is always locking each other with interim locking projection 28.Thus, keeper 40 becomes and is always maintained in the state of connector shell 20.
Additionally, fixture etc. is inserted into make keeper 40 move downwards from keeper installing hole 23 between keeper installing hole 23 and keeper 40 time, there is following situation: be applied with bigger power, and in order to cross formal locking projection 27 and the locking plate 46 of elastic deformation moved to temporary card allocation before elastic recovery.But, according to present embodiment, interim locking pawl 47 and interim locking projection 28 are formed at the rear of formal locking pawl 48 and formal locking projection 27 with staggering, even therefore when the front part of locking plate 46 deforms to width outer elastic, the rear section of locking plate 46 is without the state of the elastic deformation becoming the degree unlocked so that interim locking pawl 47 and interim locking projection 28 such that it is able to suppress to release with formal locking projection 27 at formal locking pawl 48 to make interim locking pawl 47 release locking from interim locking projection 28 under the locking impetus.Thus, even when to keeper 40 to when applying bigger power as the lower section extracting direction, it is also possible to suppress keeper 40 debit balance gesture to deviate from from connector shell 20.
As mentioned above, according to present embodiment, when making keeper 40 move from formal catch positions to temporary card allocation, the position of locking plate 46 elastic deformation becomes the front side being formed with formal locking pawl 48, and the amount of bow of the locking plate 46 being formed with the rear side of interim locking pawl 47 reduces.Thus, it is formed with the locking plate 46 of the rear side of interim locking pawl 47 and will not become the state of the elastic deformation releasing locking degree so that interim locking pawl 47 with interim locking projection 28 such that it is able to suppress locking plate 46 also to release locking with interim locking projection 28 under the impetus unlocked with formal locking projection 27.
And, according to present embodiment, interim locking projection 28 is quantitatively formed quantitatively bigger with the card of formal locking pawl 48 than formal locking projection 27 with the card of interim locking pawl 47 on projected direction, therefore to release the locking of interim locking projection 28 and interim locking pawl 47, it is necessary to make locking plate 46 than releasing formal locking projection 27 and the card timing of formal locking pawl 48 deforms to width outer elastic further.Thereby, it is possible to suppress keeper 40 debit balance gesture to deviate from from connector shell 20 further.
And then, according to present embodiment, the interim locking pawl of upper end-face edge 47 at locking plate 46 is integrally formed continuously with formal locking pawl 48, compared with situation about therefore separating in the longitudinal direction with interim locking pawl and formal locking pawl and formed, the intensity that can make locking plate 46 entirety improves, and can reduce the length dimension of the fore-and-aft direction of keeper.
