And, anti-delinking part 41 by terminal engaging portion 44, be projected in cavity 21 and from rear by the engaging of cloudy type terminal, cloudy type 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 to prevent the position of cloudy type terminal from deviating from cavity 21, and temporary card allocation is that terminal engaging portion 44 is kept out of the way and allows the position that cloudy type terminal inserts or extracts from cavity 21 to cavity 21 in cavity 21.Thus, at cloudy type terminal, be contained under the state in cavity 21, when anti-delinking part 41 chimeric to till formal catch positions time, by terminal engaging portion 44 from rear by the engaging of cloudy type terminal, thereby utilize protuberance 22 and terminal engaging portion 44 by the dual engaging of cloudy type terminal.
And, as shown in Figure 3 and Figure 4, retainer 40 becomes the state that a part for anti-delinking part 41 and sticking department 42 is given prominence to from the bottom surface of connector shell 20 downwards at temporary card allocation place, as shown in Figure 6 and Figure 7, it is chimeric that retainer 40 sentences in formal catch positions the state being contained in completely in retainer installing hole 23, and the bottom surface of the bottom surface of connector shell 20, the bottom surface of anti-delinking part 41 and sticking department 42 becomes the state on the same face roughly.
As shown in Figures 9 to 11, pair of locking portion 42 forms tabular, adjacent and form at the rear of anti-delinking part 41.And sticking department 42 is configured to be possessed: base plate 45, from the Width both ends of anti-delinking part 41, rearward extend; And locking plate 46, from base plate 45, erect upward.In addition, in Fig. 9, take paper left nearby side as rear, take the right-hand inboard of paper as front.
Locking plate 46 is formed as the rectangular flat shape thinner than base plate 45 thicknesss of slab.Locking plate 46 is integrally formed in the Width outside of the upper end-face edge of base plate 45, and can as fulcrum to Width outer elastic, be out of shape take the base end part being connected with base plate 45.
On the other hand, the two side of connector shell 20 20A be formed with respectively for make strain the through hole 26 kept out of the way of locking plate 46.As shown in Figure 1, through hole 26 is formed in longitudinal longer essentially rectangular shape on fore-and-aft direction, and, as shown in Fig. 4 and Fig. 7, in the above-below direction substantial middle portion of sidewall 20A, sidewall 20A broad ways is connected and formed.
The terminal part of locking plate 46 can enter the inner space of through hole 26, and the terminal part of the locking plate 46 being out of shape to Width outer elastic enters into the inner space of through hole 26, thereby allows that locking plate 46 is out of shape to Width outer elastic.
And as shown in Fig. 1, Fig. 4 and Fig. 7, two inwalls that are cavity 21 sides in the Width inner side of sticking department accommodation section 25 are formed with respectively: formal engaging projection 27, remains on formal catch positions by retainer 40; And interim engaging projection 28, retainer 40 is remained on to temporary card allocation.
Formal engaging projection 27 is given prominence to and is formed to Width outside from the inwall of cavity 21 sides, and forms the form of extending along fore-and-aft direction.And formal engaging projection 27 forms section essentially rectangular shape, the upper surface of formal engaging projection 27 is the formal engaging face 27A of raised sides.
With formal engaging projection 27 similarly, interim engaging projection 28 is outstanding and form to Width outside from the inwall of cavity 21 sides, and forms the form of extending along fore-and-aft direction.And, interim engaging projection 28 is further given prominence to and is formed to Width outside than formal engaging projection 27, it has the interim engaging face 28A of raised sides extending to Width outside from the inwall of cavity 21 sides on top, and forms the form that approaches cavity 21 sides slightly downwards from the outboard end of the interim engaging face 28A of raised sides is extended downwards along with extending.
And, it is downside near the open side of sticking department accommodation section 25 that interim engaging projection 28 is configured in than formal engaging projection 27, and the length dimension of the fore-and-aft direction of interim engaging projection 28 is set to the length dimension of the fore-and-aft direction of formal engaging projection 27 roughly the same.And interim engaging projection 28 is formed at the fore-end near the region of rear side than the back-end location of formal engaging projection 27, the front position of interim engaging projection 28 is configured in and the back-end location of formal engaging projection 27 overlapping position on above-below direction.That is, formal engaging projection 27 and interim engaging projection 28 stagger and form on fore-and-aft direction and above-below direction.
On the other hand, as shown in Figure 9 and Figure 10, at the upper end-face edge of locking plate 46, be formed with: interim locking pawl 47, can with interim engaging projection 28 engagings; And formal locking pawl 48, can with formal engaging projection 27 engagings.And interim locking pawl 47 and formal locking pawl 48 are integrally formed continuously on fore-and-aft direction.
And, with interim locking pawl 47 similarly, formal locking pawl 48 is side-prominent and form in from the upper end-face edge of locking plate 46 to Width, the jag of formal locking pawl 48 is formed as with the jag of interim locking pawl on the same face.
And, the lower surface of formal locking pawl 48 be can with the formal engaging face 48A of the formal engaging face 27A of the raised sides of formal engaging projection 27 engaging, it is formed as in the same face with the interim engaging face 47A of interim locking pawl 47.And, formal engaging face 48A is formed as on fore-and-aft direction longer than the formal engaging face 27A of raised sides, and set under the state of formal engaging face 48A and the formal engaging face 27A of raised sides engaging, the formal engaging face 27A entirety of raised sides is contacted with formal engaging face 48A face.
When retainer 40 moves back and forth between temporary card allocation and formal catch positions, formal locking pawl 48 slides in formal engaging projection 27.Thus, front side half part that is formed with the locking plate 46 of formal locking pawl 48 makes formal locking pawl 48 cross formal engaging projection 27 to the distortion of Width outer elastic, thereby makes locking plate 46 elastic recoveries.; locking plate 46 is to be out of shape to Width outer elastic to the mode of oblique front upper place expansion; rear side half part that is formed with the locking plate 46 of interim locking pawl 47 does not almost have strain, and interim locking pawl 47 is less to the amount of displacement outside Width than formal locking pawl 48 to the amount of displacement outside Width.
And, anti-delinking part 41 is configured in temporary card allocation, utilize the interim engaging face 28A of raised sides from the interim engaging face 47A of below engaging, thereby retainer 40 is remained on to temporary card allocation, anti-delinking part 41 is configured in formal catch positions, utilize the formal engaging face 27A of raised sides from the formal engaging face 48A of below engaging, thereby retainer 40 is remained on to formal catch positions.
And, as shown in Fig. 4 and Fig. 7, interim locking pawl 47 from locking plate 46 to Width in side-prominent amount form greatlyr from the outstanding amount of locking plate 46 than formal locking pawl 48, the length dimension of the Width of the engaging amount under the interim engaging face 28A of raised sides of the interim engaging projection 28 in temporary card allocation place and the state of the interim engaging face 47A engaging of interim locking pawl 47 is set to, length dimension than the Width of the engaging amount under the state of the formal engaging face 48A engaging of the formal engaging face 27A of raised sides in the formal engaging projection 27 in formal catch positions place and formal locking pawl 48 is large.Thus, can make the interim engaging face 28A of raised sides large with the area of formal engaging face 48A engaging with the formal engaging face 27A of Area Ratio raised sides of interim engaging face 47A engaging, thereby can make the confining force of retainer 40 at temporary card allocation place higher than the confining force of the retainer 40 at formal catch positions place.
And, with the interim locking pawl 47 of ratio in locking plate 46 near compared with the part of base end part side, the formal locking pawl 48 of ratio in locking plate 46 forms thicklyer near the part of base end part side, and the leading section of formal locking pawl 48 and front edge from locking plate 46 are integrally formed to reinforced wall 49 side-prominent and that form in Width.That is, take between formal locking pawl 48 and interim locking pawl 47 as 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, can make locking plate 46 be difficult for being out of shape to Width outer elastic in formal catch positions.Thus, at the formal locking pawl 48 formal catch positions place less with the engaging amount of interim engaging projection 28 than interim locking pawl 47 with the engaging amount of formal engaging projection 27, can make the confining force of retainer 40 improve.
Present embodiment is structure as above, then, 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 23 from the below of connector shell 20, and retainer 40 is moved upward with respect to connector shell 20.In this process, the interim locking pawl 47 of locking plate 46 slides in interim engaging projection 28, the rear section of locking plate 46 is out of shape as fulcrum to Width outer elastic take the base end part of this locking plate 46, thereby makes locking plate 46 to be out of shape to Width outer elastic to the mode of oblique back upper place expansion.
Then, as shown in Figure 4, when the interim locking pawl 47 sliding in interim engaging projection 28 is crossed interim engaging projection 28, the interim engaging face 47A of interim locking pawl 47 is by the interim engaging face 28A of raised sides of interim engaging projection 28 from below engaging, and retainer 40 is maintained at temporary card allocation.And under this state, the terminal engaging portion 44 of anti-delinking part 41 is kept out of the way in cavity 21, cloudy type terminal can be plugged with respect to cavity 21.Then, cloudy type terminal is inserted in cavity 21 from rear, make cloudy type terminal be inserted into correct position, thereby utilize protuberance 22 to prevent that cloudy type terminal from deviating from cavity 21.
Then, retainer 40 is further moved upward with respect to connector shell 20.In this process, the formal locking pawl 48 of locking plate 46 slides in formal engaging projection 27, the front part of locking plate 46 is out of shape as fulcrum to Width outer elastic take the base end part of this locking plate 46, and locking plate 46 is to be out of shape to Width outer elastic to the mode of oblique front upper place expansion.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 is out of shape to Width outer elastic.
Then, as shown in Figure 7, when the formal locking pawl 48 of locking plate 46 is crossed formal engaging projection 27, locking plate 46 elastic recoveries, thereby the formal engaging face 48A that makes formal locking pawl 48 is by the formal engaging face 27A of raised sides of formal engaging projection 27 from below engaging, and retainer 41 is maintained at formal catch positions.And under this state, the terminal engaging portion 44 of anti-delinking part 41 is projected in cavity 21, cloudy type terminal, from rear engaging, is prevented to cloudy type terminal deviates from cavity 21.Thus, utilize protuberance 22 and terminal engaging portion 44 by the dual engaging of cloudy type terminal, complete connector 10.
Then, to waiting the situation that retainer 40 is moved to temporary card allocation from formal catch positions to describe because safeguarding.
In the situation that retainer 40 is moved from formal catch positions to temporary card allocation, will between the insertion retainer installing holes 23 such as fixture and retainer 40 and in mode retainer 40 being pulled out downwards from retainer installing hole 23, move.Now, locking plate 46 becomes state contrary when moving from temporary card allocation to formal catch positions.That is, by the formal locking pawl 48 of locking plate 46, in formal engaging projection 27, slide, make the front part of locking plate 46 to the distortion of Width outer elastic, locking plate 46 is to be out of shape to Width outer elastic to the mode of oblique front upper place expansion.Then, as shown in Figure 4, when the formal locking pawl 48 of locking plate 46 is crossed formal engaging projection 27, the interim engaging face 47A of interim locking pawl 47 is by the interim engaging face 28A of raised sides of interim engaging projection 28 from below engaging, and anti-delinking part 41 is maintained at temporary card allocation.; by formal locking pawl 48, in formal engaging projection 27, slide; make locking plate 46 to be out of shape to Width outer elastic to the direction of oblique front upper place expansion; but interim locking pawl 47 and interim engaging 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 interim locking pawl 47 and interim engaging projection 28 state of engaging always each other.Thus, retainer 40 becomes the state that is always held in connector shell 20.
In addition, when fixture etc. being inserted between retainer installing hole 23 and retainer 40 and retainer 40 is moved downwards from retainer installing hole 23, there is following situation: applied larger power, and the locking plate 46 of strain moved to temporary card allocation before elastic recovery in order to cross formal engaging projection 27.But, according to present embodiment, interim locking pawl 47 and interim engaging projection 28 stagger and form at the rear of formal locking pawl 48 and formal engaging projection 27, even under the state being therefore out of shape to Width outer elastic in the front part of locking plate 46, the rear section of locking plate 46 can not become the state of the strain that makes interim locking pawl 47 and the degree that engaging projection 28 unlocks temporarily yet, thereby can be suppressed at formal locking pawl 48 and formal engaging projection 27 removes under the impetus of engaging and makes interim locking pawl 47 remove engaging from interim engaging projection 28.Thus, even in the case of to retainer 40 to as extract direction below apply larger power, also can suppress retainer 40 debit balance gesture and deviate from from connector shell 20.
As mentioned above, according to present embodiment, when retainer 40 is moved from formal catch positions to temporary card allocation, the position of locking plate 46 strains becomes the front side that is formed with formal locking pawl 48, and the amount of bow that is formed with the locking plate 46 of the rear side of interim locking pawl 47 reduces.Thus, the locking plate 46 that is formed with the rear side of interim locking pawl 47 can not become and makes interim locking pawl 47 and interim engaging projection 28 remove the state of the strain of the degree of engaging, thereby can suppress locking plate 46, under the impetus unlocking with formal engaging projection 27, removes engaging with interim engaging projection 28 yet.
And, according to present embodiment, interim engaging projection 28 forms greatlyr with the engaging amount of formal locking pawl 48 than formal engaging projection 27 with the engaging amount of interim locking pawl 47 on projected direction, therefore in order to remove the engaging of interim engaging projection 28 and interim locking pawl 47, need to make locking plate 46 and further to Width outer elastic, be out of shape when removing formal engaging projection 27 with the engaging of formal locking pawl 48.Thus, can further suppress retainer 40 debit balance gesture deviates from from connector shell 20.
And then, according to present embodiment, the interim locking pawl 47 of upper end-face edge at locking plate 46 is integrally formed continuously with formal locking pawl 48, the situation of therefore separating on fore-and-aft direction with formal locking pawl with interim locking pawl and form is compared, can make the intensity of locking plate 46 entirety improve, and can reduce the length dimension of the fore-and-aft direction of retainer.
