Abstract
An object of the present invention is to improve the reliability of a function of retaining locking portions while miniaturizing a connector. Locking portions 15B are provided with such reinforcing ribs 18 as to partly project from surfaces of the locking portions 15B facing deformation spaces 21 B, and escaping portions 47 for accommodating the reinforcing ribs 18 are formed at positions facing the locking portions 15B in a surface of a wall portion 41 facing the deformation spaces 21. Since the rigidity of the locking portions 15B is increased by forming the reinforcing ribs 18, the reliability of a function of retaining terminal fittings 30 is higher. Further, in the process of inserting the terminal fittings 30, the reinforcing ribs 18 are accommodated into the escaping portions 47 as the locking portions 15 are resiliently deformed. This can avoid the enlargement of a connector along the deforming direction of the locking portions resulting from the formation of the reinforcing ribs 18.
Description
The present invention relates to connector and electrical connector.
The open No.H05-182712 of Japanese unexamined patent publication No. discloses a connector, and its structure makes, by being inserted into clamped nipple in the terminal cavities of shell with the lock part incompatible maintenance that matches, this lock part forms along the inwall of terminal cavities.
In above-mentioned connector, as the device that makes connector miniaturization (reducing its height), lock part attenuation.Because the rigidity of lock part weakens because of the lock part attenuation, so may reduce the reliability of the function that keeps clamped nipple.
The open No.H05-182712 of Japanese unexamined patent publication No. discloses another connector, and its structure makes, by cooperate the clamped nipple in the terminal cavities that keeps being inserted into shell with the lock part, this lock part forms along the inwall of terminal cavities.
In this class connector, the anchor clamps insertion opening that anchor clamps pass in the front surface that is formed on shell is inserted in the deformation space of lock part, and the lock part is making clamped nipple break away from strain on the direction that cooperates with anchor clamps, thereby the lock part can break away from the state that is kept by the lock part.
Make under the above-mentioned situation of connector miniaturization, lock part and deformation space diminish, and anchor clamps insertion opening necessarily diminishes.In this case, there is the problem that is difficult to the anchor clamps insertion is passed anchor clamps insertion opening.
And under female terminal fitting and situation that line is connected, the height of the tubular portion that will be connected with the male terminal joint is equal substantially with the height of the bobbin part that will be connected with line.Therefore, the height that is used to hold the cavity of this female terminal fitting is the height (referring to the open No.H09-153386 of Japanese unexamined patent publication No.) of bobbin part in whole length range adjusted.
Yet along with the carrying out of connector miniaturization, it is less and shorter that the clamped nipple oneself height becomes.So, because and the relation between the diameter of the line that will connect, so the bobbin part can become higher than tubular portion.Have the unified height consistent with the height of bobbin part if cavity forms, then will become meaningless with the part increase of the corresponding connector shell of tubular portion, this does not have help to miniaturization.
Therefore, consider height, change the height of cavity according to bobbin part and tubular portion.Then, the outer surface of connector shell and the corresponding part of bobbin part and and the corresponding part of tubular portion between boundary produce step.With rise to along with the matching connector shell and the corresponding part of tubular portion, if connector device is compared before being fitted in the socket of male housing, the height of connector shell can be shorter.
Yet although can reduce height, the degree of depth that enters into socket along closure is restricted to and rises to and the corresponding part of tubular portion, promptly in the zone of bobbin before partly.When two connector shells connected, this had hindered the shortening of connector length.
And, be used for keeping the lock part of clamped nipple to be integrally formed in the cavity of connector.The lock part is in forward the form of the cantilever beam that extends, and strain up and down.In this connector, the basal surface of cavity often prevents the excessive strain of lock part.Prior art is at the open No.H05-182712 of for example Japanese unexamined patent publication No..
Accompanying drawing 32 shows the connector with above-mentioned functions, but with the open No.H05-182712 of Japanese unexamined patent publication No. in disclosed connector different.
As shown in accompanying drawing 32, connector shell 150 must be provided with deformation space 152 below lock part 151, the strain that this deformation space has lock part 151 is suppressed at needed height in its elastic limit scope, and this has hindered the height that shortens connector shell 150.In other words, lock part 151 forms the feasible outer surface that is exposed to connector shell 150, and to be projected into the mode elastically deformable of connector shell 150 outsides.Under the situation that adopts this structure, owing to need in connector shell 150, not provide deformation space, so can shorten the height of connector.
Yet, must provide separator in this case, to prevent the excessive deformation of lock part 151.

When from terminal cavities 11A, 11B, withdrawing from clamped nipple 30, narrower and long anchor clamps (not shown) to small part is passed or can be passed anchor clamps to small part and insert opening 24, and the anchor clamps receiving surface 16 of its guide end and lock part 15A, 15B is kept in touch substantially, these anchor clamps insert opening and are formed in the front surface of shell 10.Then, so that locking projection 17 makes lock part 15A, 15B force strain towards deformation space 21A, 21B from the mode of lock hole or lock part or locking step disengaging cooperation.In this way, with or can make clamped nipple 30 break away from the state that keeps by lock part 15A, 15B.
Protection member 40 is made by for example synthetic resin; and comprise (form that preferably is in rectangular slab substantially) wall part 41, pair of sidewalls 42 and/or rear wall 43; this wall part is basically parallel to horizontal (end) surface of shell 10; this sidewall is from relatively laterally (left side and the right) edge of wall part 41 or stretch out the marginal portion or outstanding, and this rear wall is from stretching out near the rear end of wall part 41 or rear end part or its or outstanding.Be preferably in the inner surface of each sidewall 42 and all be formed with latch recess 44.The effect of terminal locking part 45A is preferably played in the upper end of rear wall 43, and this terminal locking part can be with from the receding side, preferably substantially from behind to small part be inserted into one (on) tubular portion 31 of clamped nipple 30 among the terminal cavities 11A on the layer matches.And, rear wall 43 is formed with at least one through hole 46 that penetrates on forward and backward directions FBD, wherein the lower limb of this through hole 46 partly plays the effect of terminal locking part 45B, this terminal locking part can be with from the receding side, and preferably the tubular portion 31 that is inserted into the clamped nipple 30 among the terminal cavities 11B on another (descending) layer to small part substantially from behind matches.Therefore, protection member 40 can play the effect of retainer, is used for clamped nipple 30 best double locking to respective terminal chamber 11.
This protection member 40 is laterally or from installation side, preferably be installed to from below substantially maybe can be installed in the shell 10 or on the shell 10, and relative sidewall 42 outer surfaces basic and shell 10 aligns.The protection member 40 that is installed in the shell 10 or be installed on the shell 10 can be remained on part latched position (as preferred primary importance) 1P place; perhaps complete latched position (as the preferred second place) 2P place; at this part latched position place; the part locking projection 25 of latch recess 44 and shell 10 and locking projection 26 match (referring to accompanying drawing 7) fully; this complete latched position is positioned at part latched position 1P top or close more shell 10; at this complete latched position place, latch recess 44 match with the complete locking projection 26 of shell 10 (referring to accompanying drawing 8).
Wall part 41 has the opening 23 basic corresponding shape (this shape is preferably close with opening 23) of the deformation space 21B in the lower floor in horizontal (end) surface with shell 10.When protection member 40 is positioned at part latched position (primary importance) 1P place; wall part 41 is positioned at from downward or outwards outstanding position (highly), horizontal (end) surface of shell 10; and wall part 41 interior (on) surface (basic side is to the surface of deformation space 21B) and be between outer (descend) surface of lock part 15B of free state and be provided with a space (referring to accompanying drawing 2 and 3), this space is used to make lock part 15B can arrive the degree of permission clamped nipple 30 insertions towards deformation space 21B strain.When protection member 40 is in complete latched position (second place) when locating; the lower surface of wall part 41 (outer surface) preferably flushes substantially with the basal surface (outer surface) of shell 10; and wall part 41 interior (on) outer (descending) surperficial contact of the basic front end with the lock part 15B that is in free state in surface; perhaps face substantially with it, limit very little gap (referring to accompanying drawing 1) simultaneously.At complete latched position (second place) 2P place, prevent or limited the strain (in the strain that make locking projection 17 and clamped nipple 30 break away from the direction that cooperate on) of lock part 15B substantially towards deformation space 21B.
Wall part 41 is formed with one or more, and preferably several withdraw from part 47, and it is basic corresponding with the lock part 15B in the lower floor that this withdraws from part, and this withdraws from part 47 lateral separation or arrangement each other.This withdraws from part 47 and is arranged to correspondingly substantially with deep floor 18, and its length and/or width be arranged so that, deep floor 18 can hold or be assembled to and withdraws from the part 47 to small part.This withdraws from part 47 transparent walls part 41 (promptly on the bearing of trend of deep floor 18 or on the deformation direction of lock part 15) vertically.When protection member 40 is in part latched position (primary importance) 1P place; withdraw from the following or outside that part 47 is positioned at the deep floor 18 of the lock part 15B that is in free state; and when protection member 40 was in complete latched position (second place) 2P place, deep floor 18 to small part was received into and withdraws from the part 47.The reinforcing section 48 that is in transversely the floor form of extending is formed on the front end (not with the corresponding zone of lock part 15B, promptly in lock part 15B region in front) of wall part 41 and locates to project upwards.
Next the function of present embodiment is described.
When to small part being inserted in terminal cavities 11A, 11B along direction of insertion ID clamped nipple 30, protection member 40 at first remains on part latched position (primary importance) 1P place.In this state, because wall part 41 is opened with the lock part 15B perpendicular separation in the lower floor, so allow the strain of lock part 15B, and terminal locking part 45A, 45B withdraw laterally or downwards from terminal cavities 11A, 11B (the insertion passage of clamped nipple 30) towards deformation space 21B.So, allow clamped nipple 30 to be inserted among terminal cavities 11A, the 11B.In this state, clamped nipple 30 to small part is inserted among corresponding terminal cavities 11A, the 11B.Because lock part 15A, 15B are during insertion towards deformation space 21A, 21B strain or can strain, so can not hinder the insertion of clamped nipple 30 basically.
Be inserted into when being in the main true the position when terminal connects 30, lock part 15A, 15B return elastically or return elastically free state towards free state, lock part 17 and lock hole or lock part or locking step are cooperated, thereby clamped nipple 30 is maintained.After this, the protection member 40 that is in part latched position (primary importance) 1P place upwards promotes or moves to complete latched position (second place) 2P place.Then, terminal locking part 45A, 45B match with (preferably basic rectangle) tubular portion 31, thereby keep clamped nipple 30.In other words, clamped nipple 30 preferably is subjected to lock part 15A, 15B and 40 double locking of protection member.When protection member 40 moves to complete latched position (second place) 2P place; wall part 41 to small part enters the deformation space of lock part 15B; contact or substantially very closely face their (promptly and have between them very little gap) with the lower surface of lock part 15B with basic, and lock floor 18 to small part and be received into and withdraw from the part 47.In this state, because wall part 41 has been inserted into former among the terminal cavities 11B in the lower floor for clamped nipple 30 thereby has prevented the strain of lock part 15B, so clamped nipple 30 preferably is subjected to lock part 15B, terminal locking part 45B and wall part 41 3 re-locks.
When the clamped nipple 30 in will remaining on terminal cavities 11A, 11B withdrawed from, protection member 40 at first moved to part latched position (primary importance) 1P place, cooperated so that terminal locking part 45A, 45B preferably break away from clamped nipple 30.And the lock part 15B in the lower floor preferably breaks away from wall part 41 and prevents its state towards deformation space 21B strain.After this, the anchor clamps (not shown) 10 front side inserts and passes anchor clamps and insert opening 24 to small part from shell, contacting substantially with the anchor clamps receiving surface 16 of lock part 15A, 15B, and operation makes lock part 15A, 15B towards deformation space 21A, 21B (promptly it being broken away from the direction that cooperates with clamped nipple 30) pressure strain.In this way, clamped nipple 30 breaks away from the state that is kept by lock part 15A, 15B.After this, under the situation of anchor clamps, for example, clamped nipple 30 can be pulled back by pinching and pulls wire or by with another kind of method operation clamped nipple 30 with the cancellation of this hold mode.
As mentioned above, according to present embodiment, lock part 15A, 15B are provided with from surface (lower surface) the part outstanding deep floor 18,20 of its basic side to deformation space 21A, 21B, and this deep floor 18,20 has strengthened the rigidity of lock part 15A, 15B.Therefore, the reliability of the function of maintenance clamped nipple 30 is higher.
And; the surface of wall part 41 is formed with the position of lock part 15B at basic side withdraws from part 47; this surface substantially with lower floor on deformation space 21B face mutually; and when protection member 40 when remaining on complete latched position (second place) 2P place, deep floor 18 is at least partially housed in and withdraws from the part 47.This can be avoided connector to increase along the deformation direction of lock part 15B, and the formation of deep floor 18 has caused the distortion of this lock part.
Owing to remain under the situation at complete latched position (second place) 2P place at protection member 40; make basic side enter the deformed region of lock part 15B in the deformation space 21 to wall part 41 to the small part of the deformation space 21B on last (outward) layer; so compare with the situation that the strain requisite space of lock part is limited, along the deformation direction of lock part 15B shell 10 can be made less.And, because the opening 23 of the deformation space 21B in the outer surface of shell 10 is preferably basic fully by wall part 41 sealings of protection member 40 to small part, passes the opening 23 of deformation space 21B and enter in the shell 10 so can hinder or prevent foreign.
And; because wall part 41 contacts with lock part 15B substantially; to prevent lock part 15B, make protection member 40 remain on complete latched position (second place) 2P place, so the reliability of the function of maintenance clamped nipple 30 is higher towards deformation space 21B strain.
Similarly; because terminal locking part 45A, the 45B of protection member 40 matches or can match with it with the clamped nipple 30 among terminal cavities 11A, the 11B; make protection member 40 remain on complete latched position (second place) 2P place, so the reliability of the function of maintenance clamped nipple 30 is higher.
And, by with withdraw from part 47 transparent walls parts 41 or be arranged in the wall part 41, so compare for the situation of base recess with withdrawing from part, can be along less with the connector making of the deformation direction of lock part 15B.
Therefore, in order to improve the reliability of the function that keeps the lock part, make the connector miniaturization simultaneously, one or more lock part 15B are provided with one or more deep floors 18, it is outstanding that it is divided the upper surface of deformation space 21B from lock part 15B basic side, and the part 47 that withdraws from that is used for holding deep floor 18 is formed in the face of the position in the face of lock part 15B, the surface of the wall part 41 of deformation space 21.Because, strengthened the rigidity of lock part 15B by forming deep floor 18, so the reliability of the function of maintenance clamped nipple 30 is higher.And in inserting the process of clamped nipple 30, along with lock part 15 strains, deep floor 18 to small part is held maybe can be received into and is withdrawed from the part 47.This can be avoided connector to increase along the deformation direction of lock part, and the formation of deep floor 18 has caused the distortion of this lock part.

This opening forms member 40 horizontal (from following) on installation direction MD and is installed to the shell 10 substantially or is installed on the shell 10, and the relative substantially sidewall 42 and the outer surface of shell 10 align.On installation direction MD, be installed in the shell 10 or be installed to this opening in the shell 10 and form member 40 and can remain on part latched position (as preferred primary importance) 1P place to small part, perhaps complete latched position (as the preferred second place) 2P place, at this part latched position place, the part locking projection 25 of latch recess 44 and shell 10 and locking projection 26 match (referring to accompanying drawing 17) fully, this complete latched position is positioned at part latched position 1P top (perhaps more near shell 10), at this complete latched position place, latch recess 44 match with the complete locking projection 26 of shell 10 (referring to accompanying drawing 18).
Horizontal (end) surface that wall part 41 preferably has basic and a shell 10 is the corresponding shape of opening of the deformation space 21B on (descending) layer (best this can the partially enclosed at least opening of shape) at home and abroad.When opening forms member 40 ' when being positioned at part latched position (primary importance) 1P place, wall part 41 is positioned at from outside or outstanding downwards position (highly), horizontal (end) surface of shell 10, and wall part 41 interior (on) surface (basic side is to the surface of deformation space 21B) and be in free state or be not provided with a space between outer (descend) surface of the lock part 15B of deflection state substantially, this space is used to make lock part 15B can arrive the degree of permission clamped nipple 30 insertions towards deformation space 21B strain.When opening forms member 40 ' be positioned at complete latched position (second place) when locating, the lower surface of wall part 41 (outer surface) preferably flushes substantially with the basal surface (outer surface) of shell 10, and wall part 41 interior (on) outer (descending) surperficial contact of the basic front end with the lock part 15B that is in free state in surface, perhaps very approaching with it, perhaps face substantially with it, limit very little gap simultaneously.At complete latched position (second place) 2P place, prevent or limited the strain (in the strain that make locking projection 19 and clamped nipple 30 break away from the direction that cooperate on) of lock part 15B towards deformation space 21B.
Opening forms part 49 substantially along the front end of wall part 41 or stretch out in its vicinity or outstanding, and edge part or inner edge portion branch are formed with notch (notch) thereon.The inside of each notch or distal part or top (preferably being the first half substantially) all are the notches 50 of broad, and its outside or bottom (preferably being the latter half substantially) is narrower notch 51.Each tongue piece inserts opening 17 and is formed by the groove 50 of broad and the corresponding recess 16 of shell 10, and this tongue piece inserts opening and preferably has laterally long rectangular shape substantially.These narrower notch 51 basic bottoms with tongue piece insertion opening 17 are connected, and also are connected with the front end of deformation space 21B in the lower floor.Anchor clamps J can be inserted in these narrower notches 51 to small part.Each anchor clamps inserts opening 52 and all inserts opening 17 and 51 formation of corresponding narrower notch by tongue piece, and comprises them.
When opening forms member 40 maintenances or is positioned at part latched position (primary importance) 1P place, the opening that opening forms member 40 form part 49 from the antetheca 12 of shell 10 downwards away from or outwards keep at a certain distance away, and by the notch 50 that vertically separates recess 16 and broad, tongue piece is inserted opening 17 insert opening 52 vertical widening, shown in accompanying drawing 12 and 13 with anchor clamps.When opening forms member 40 maintenances or is positioned at complete latched position (second place) 2P place, opening form part 49 interior (on) surface contacts with horizontal (end) end surfaces of the antetheca 12 of shell 10 substantially, and compare with the situation that is positioned at part latched position 1P place, lean on nearerly by the notch 50 that makes recess 16 and broad, tongue piece is inserted opening 17 insert opening 52 vertical widening, shown in accompanying drawing 11 and 14 with anchor clamps.
Next, the function of present embodiment is described.
When being inserted among terminal cavities 11A, the 11B to small part clamped nipple 30 on direction of insertion ID, opening forms member 40 ' at first keep or is positioned at part latched position (primary importance) 1P place.In this state, because wall part 41 is vertically spaced apart with the lock part 15B on outer (descending) layer, so allow lock part 15B towards deformation space 21B strain, and terminal locking part 45A, 45B outwards or downwards withdraw from terminal cavities 11A, 11B (the insertion passage of clamped nipple 30).So, allow clamped nipple 30 to small part to be inserted among terminal cavities 11A, the 11B.Clamped nipple 30 is inserted among respective terminal chamber 11A, the 11B to small part in this state.Because lock part 15A, 15B are during insertion towards deformation space 21A, 21B strain, so can not hinder the insertion of clamped nipple 30.
When clamped nipple 30 is inserted into the position that is in the main true, lock part 15A, 15B return elastically or are back to free state towards its free state, make the lock hole of locking projection 19 and rectangular tube portion 31 or locking recess or lock part or locking step (not shown) match, thereby, clamped nipple 30 maintained or decide.After this, the opening that is positioned at part latched position (primary importance) 1P place forms member 40 ' upwards promote or shift or move to complete latched position (second place) 2P on installation direction MD, perhaps promotes or shifts or move towards complete latched position 2P.Then, terminal locking part 45A, 45B preferably match with (preferably being rectangle substantially) tubular portion 31, thereby keep clamped nipple 30.In other words, clamped nipple 30 preferably is subjected to lock part 15A, 15B and opening forms member 40 ' double locking.When opening form member 40 ' on the installation direction MD when complete latched position (second place) 2P moves or moves to this position, wall part 41 to small part enters in the deformation space of lock part 15B, substantially contact with outer (descending) surface of lock part 15B, perhaps very closely right with its basic side, and deep floor 20 to small part is received into and withdraws from the part 47.In this state, because wall part 41 preferably prevents the strain of the lock part 15B of the clamped nipple 30 on outer (descending) layer, so clamped nipple 30 preferably is subjected to lock part 15B, terminal locking part 45B and wall part 41 3 re-locks.
Similarly, form member 40 ' keep or be positioned under the situation at complete latched position (second place) 2P place at opening, reinforcing section 48 interior (on) gap between (end) surface outward of (preferably being rectangle substantially) tubular portion 31 of surface and clamped nipple 30 is narrower than the thickness of anchor clamps J.So, even oppositely inserting, anchor clamps J passes anchor clamps insertion opening 52, it also can contact with reinforcing section 48 before arriving lock part 15B substantially.Therefore, form member 40 ' keep or be positioned under the situation at complete latched position (second place or installation site) 2P place at opening, anchor clamps J can not make lock part 15B strain on the direction that unlocks.
When the clamped nipple 30 in will remaining on terminal cavities 11A, 11B is released, opening form member 40 ' at first with the relative substantially direction of installation direction MD on move to part latched position (primary importance) 1P place, terminal locking part 45A, 45B are cooperated with clamped nipple 30 disengagings.And the lock part 15B on outer (descending) layer breaks away from wall part 41 and prevents its state towards deformation space 21B strain.And, (descend) tongue piece on the layer to insert opening 17 outward and vertically be divided into the open area of vertically widening that anchor clamps insert opening 52, and/or outer (end) surface of (preferably being rectangle substantially) tubular portion 31 of clamped nipple 30 and wall part 41 interior (on) the gap of vertically widening between the surface.
In this state, anchor clamps J inserts to small part and maybe can be inserted in the anchor clamps insertion opening 22,52, and in the gap between tubular portion 31 and the wall part 41.At this moment, insert the vertical dimension (size between the bottom margin of the top edge of recess 16 and narrower notch 51) of opening 52, insert anchor clamps J on the layer so can be easy to (descend) outside owing to increased anchor clamps.
Contact with the anchor clamps receiving surface 18 of lock part 15A, 15B by the guiding end that makes the anchor clamps J that has inserted, and anchor clamps J tilted or turns to make its guiding end or outwards, lock part 15A, 15B are towards deformation space 21A, 21B (promptly it being broken away from the direction that cooperates with clamped nipple 30) pressure strain downwards.At this moment, because also vertically increase of the gap between (rectangle) tubular portion 31 and the wall part 41, so anchor clamps J can tilt significantly.Because clamped nipple 30 breaks away from the state that is kept by lock part 15A, 15B by making lock part 15A, 15B strain in this way, under the situation of anchor clamps J cancellation hold mode, can line 33 be pulled back by for example pinching line 33.
As mentioned above, according to present embodiment, insert anchor clamps J that the anchor clamps pass in the front surface that is formed on shell 10 insert opening 22,52 to small part and make lock part 15A, 15B strain on the direction that breaks away from clamped nipple 30, thereby clamped nipple 30 breaks away from the state that is kept by lock part 15A, 15B.(descend) fringe region that anchor clamps on the layer insert opening 52 to form member 40 ' form outward by opening, deformation space 21B in the antetheca 12 of this fringe region and shell 10 is corresponding, and this opening forms member and shell 10 is separated and can be with respect to shell 10 in that to make that anchor clamps insert on the direction that opening 52 broadens mobile.
Under the situation that adopts structure as shown in Figure 19, wherein the open area of tongue piece insertion opening 60 does not increase, and is difficult to insert anchor clamps J.Yet according to present embodiment, after inserting anchor clamps J, opening forms member 40 ' can move and makes anchor clamps insert opening 52 to broaden, as shown in Figure 15.So the operation of inserting anchor clamps J is more prone to.When not needing to insert anchor clamps J, if opening formation member 40 ' on the direction that anchor clamps insertion opening 52 is narrowed down, move, can prevent that then foreign from entering by anchor clamps insertion opening 52.
Form member 40 ' remain on complete latched position place at opening and make anchor clamps insert under the situation that opening 52 narrows down, be arranged on opening form member 40 ' on terminal locking part 45A, 45B match with clamped nipple 30, so that they are maintained.Form member 40 ' keep or be positioned under the situation that part latched position 1P place makes that anchor clamps insertion opening 52 broadens at opening, terminal locking part 45A, 45B are withdrawn into substantially with clamped nipple 30 and break away from the position that cooperates, and clamped nipple 30 breaks away from hold mode.In other words, along with mobile opening as required forms member 40 ' and withdraw from clamped nipple 30, terminal locking part 45A, 45B can and break away between the position that cooperates mobile with clamped nipple 30 in the position of matching with clamped nipple 30.So, do not need to carry out separately mobile opening form member 40 ' operation and the operation of mobile terminal lock part 45A, 45B.Therefore, operability is better.
And, when not needing to withdraw from clamped nipple 30, opening forms member 40 ' contact with lock part 15B substantially, to prevent that lock part 15B is by moving to part latched position (primary importance) 1P anchor clamps insertion opening 52 being narrowed down and towards deformation space 21B strain.So the reliability of the function of maintenance clamped nipple 30 is higher.
Therefore, be inserted into anchor clamps and insert operation in the opening in order to help anchor clamps, the fringe region that anchor clamps insert opening 52 forms member 40 ' form by opening, this fringe region is substantially corresponding with the deformation space 21B in the antetheca 12 of shell 10, this opening forms member and shell 10 is separated, and can go up in the direction (direction relative with installation direction MD) that anchor clamps insertion opening 52 is broadened and move with respect to shell 10.After small part is inserted anchor clamps J, form member 40 by mobile opening anchor clamps insertion opening 52 is broadened, help inserting the operation of anchor clamps J.And, when not needing to insert anchor clamps J,, can prevent that foreign from passing anchor clamps and inserting opening 52 and enter by making anchor clamps insert that mobile opening forms member 40 on the direction that opening 52 narrows down.

＜the three embodiment 〉
Below, with reference to accompanying drawing 20 to 29 the 3rd preferred embodiment of the present invention is described.What represent is female connector housing with 101 in the accompanying drawings, be arranged on lock arm 103 elastically deformables female connector housing 101 laterally (on) mid portion (preferably substantially in width central authorities) on surface, this lock arm is used to keep female connector housing 101 to be connected with positive connector shell 102.Lock arm 103 is preferably in its front side and is supported, and its rear side plays the effect of the end portion 103A that unlocks.Protective bulkhead 105 be preferably in be erected on the whole substantially length female connector housing 101 laterally (on) near the rear edge on surface or its, and fenestra 104 is formed in the width mid portion (preferably substantially at the width middle body) of protective bulkhead 105.The end portion 103A that unlocks of lock arm 103 passes fenestra 104 to small part, thereby can operate.
One or more, on preferably several cavitys 106 preferably are formed on one or more layers in the female connector housing 101 substantially side by side along Width, preferably on two layers.Respective cavities 106 penetrates female connector housing 101 substantially on forward and backward directions FBD, and female terminal fitting 107 can be on direction of insertion ID, preferably holds wherein to small part substantially from behind.
Female terminal fitting 107 is mainly described herein.Each female terminal fitting 107 all comprises (preferably the being rectangle substantially) tubular portion 109 that will be connected with male terminal joint 8, and is arranged on (rectangle) tubular portion 109 back and is used for the line coupling part (preferably including bobbin part 110) that is connected with line.This bobbin part 110 preferably includes wire barrel 110A and insulated tube 110B, and this wire barrel is crimping or crooked or be folded into core and be connected, and this insulated tube is with crimping or bending or be folded into the insulating coating of line and be connected.Shown in female terminal fitting 107 with or can be connected with line, and preferably be arranged to be shorter than the height of (rectangle) tubular portion 109 from the basal surface of female terminal fitting 107 to the height on the top of wire barrel 110A, but preferably be arranged to be longer than the height of (rectangle) tubular portion 109 to the height on the top of insulated tube 110B.
The height of each cavity 106 inside all changes feasible basic corresponding with the height of insulated tube 110B or corresponding, and the height of this insulated tube is higher than the height of (rectangle) tubular portion 109.So, in horizontal (end) surface of negative connector 101, basic forming projections 111 with tubular portion (insulated tube) 110 corresponding parts, this projection is preferably on the whole substantially width of female connector housing 101 outwards protrusion.
In each cavity 106, (the preferably basic cantilever shape) lock part 112 of extending substantially forward is arranged on laterally (end) wall place.The direction strain that this lock part 112 can intersect along short transverse or with the direction of insertion ID of female terminal fitting 107 in cavity 106, and can with (rectangle) tubular portion 109 that is formed on female terminal fitting 107 in or the lock hole or locking recess or lock part or the locking step (not shown) that form thereon match.The deformation space of lock part 112 be limited to one (on) in the cavity 106 on the layer, and the cavity 106 separated partition walls 113 of adjacent (upper and lower) are played the effect that prevents lock part 112 transition strains.In other words, before exceeding this excessive strain of its elastic limit, the guiding end of lock part 112 substantially with or can contact with partition wall 113, thereby do not allow its any further strain.Yet, owing to basic on the outer surface of female connector housing 101 and 112 corresponding part places, lock part are formed with poroid part or sunk part 114 (thickness that preferably has the wall thickness of female connector housing of equaling 101), so the lock part preferably is being at least partially exposed through on the whole length on the outer surface of female connector housing 101 substantially, in the cavity 106 outside this lock part is arranged on (descending) layer (being arranged near the cavity of outer surface of female connector housing 101).More particularly, when lock part 112 in the raw or not during deflection state, its outer surface or lower surface preferably flush with the basal surface of cavity 106 substantially.When lock part 112 downwards or outwards or on the direction that intersects with direction of insertion ID along with pass through of female terminal fitting 107 during strain, the guiding end at least of lock part 112 is preferably given prominence to from cavity 106.For example, when retainer 115 is positioned at part latched position (as preferred primary importance) 1P place as described later like that, even female terminal fitting 107 passes through, the guiding end of lock part 112 does not prevent that with the excessive deformation of retainer 115 inner surface of part 116 or upper surface from contacting yet, and (can contact) simultaneously to limit less clearance between them.Yet, if for example owing to be subjected to the influence of external force, female terminal fitting 107 strain in its elastic limit arrives than degree bigger above female terminal fitting 107, and then the guiding end of lock part 112 prevents that with the excessive deformation of retainer 115 part 116 from contacting substantially.
The front end of each cavity 106 forms the opening that inserts opening 117 as tongue piece in the antetheca of connector shell 101, and with after female connector housing 101 is connected, the one or more tongue pieces that are installed in the male terminal joint 108 in the positive connector shell 102 can insert to small part and pass tongue piece and insert opening 117 at positive connector shell 102.And one or more anchor clamps insert opening 118 and are formed in the antetheca of female connector housing 101, make to be connected with the bottom of tongue piece insertion opening 117 substantially.Anchor clamps to the small part that unlocks is inserted and is passed or can insert to small part and pass anchor clamps insertion opening 118, so that lock part 112 strain on the direction that unlocks.
In the example shown, retainer installing hole 119 is formed on the mid portion (preferably being arranged in vertical middle body substantially) (112 back in the lock part) of the lower surface of female connector housing 101.This retainer installing hole 119 forms respective cavities 106 basic and on adjacent (upper and lower) layer and is connected.
One or more, preferably pair of side plates 122 is arranged on (preferably relative substantially) the width side or sidepiece of terminal locking part 120.Total longitudinal size that the length of side plate 122 is arranged to slightly to be longer than terminal locking part 120 and is prevented part 116 from the excessive deformation that terminal locking part 120 is extended substantially forward.Although just on less degree, allow side plate 122 on direction away from each other, to carry out strain, thereby can keep the relative substantially width side surface of female connector housing 101 tightly from basic opposite external side.Latch recess 123 is formed in the inner surface of each side plate 122 in the position near guiding end (upper end).On the other hand, the part locking projection or first projection 124 and complete locking projection or second projection 125 are formed on each outer width side surface of female connector housing 101, this part locking projection or first projection 124 and complete locking projection or second projection 125 are essentially horizontally extended, and limit a gap simultaneously above part locking projection 102.When retainer 115 is positioned at part locking bit 1P place, have only part locking projection 124 to small part to be assembled in the latch recess 123, and cooperate with the top edge of latch recess 123, and the top edge of side plate 122 cooperates with complete locking projection 125, thereby preferably do vertical moving, and hold it in part latched position 1P place by whole retainer 115 is constrained to.On the other hand, when retainer 115 is positioned at complete latched position (as the preferred second place) 2P place, part locking projection 124 and complete locking projection 125 to small part be assembled in the latch recess 123 and with relative (lower and upper) edge mate of latch recess 123, thereby do vertical moving, and with its maintenance or be positioned at complete latched position place by whole retainer 115 is constrained to.
When retainer 115 is positioned at part latched position 1P place, excessive deformation prevents that part 116 formation have best and terminal locking part 120 essentially identical width, and horizontal (end) surface that is basically parallel to female connector housing 101 extends forward, with limit with lock part 112 between specific (that preset or predeterminable) gap.Especially, as mentioned above, the elastic deformation level of lock part 112 is guaranteed according to the needs that female terminal fitting 107 passes through in this gap.When lock part 112 in its elastic limit during strain, its guiding end basic with excessive deformation prevent part 116 interior (on) surface contacts, perhaps arrive with excessive deformation prevent part 116 interior (on) surperficial very approaching position.When retainer 115 moves towards complete latched position 2P, or when moving to complete latched position 2P place, excessive deformation prevents that part 116 to small part is assembled in the poroid part or sunk part 114 of female connector housing 101, and excessive deformation prevents that (end) surface outward of outer (descend) surface of part 116 and female connector housing 101 from preferably becoming each other and flushes substantially.When retainer 115 is positioned at complete latched position (second place) 2P place, excessive deformation prevent part 116 interior (on) the surperficial contact of basic outer (descend) in surface with lock part 112, to prevent 112 while of lock part strain on the direction that unlocks.
As shown in accompanying drawing 29, positive connector shell 102 comprises socket 126, female connector housing 101 can or be inserted in this socket to the small part assembling, also comprise one or more, several male terminal joints 108 preferably, when positive connector shell 102 was connected with female connector housing 101, this male terminal joint to small part that can be connected with female terminal fitting 107 was projected in the socket 126.
As shown in accompanying drawing 23, positive connector shell 102 can for example be installed on the printed circuit board (PCB) 140 (as preferred electric or electronic installation), and comprises socket 126, and female connector housing 101 can or be inserted in this socket to the small part assembling.When positive connector shell 102 was connected with female connector housing 101, a side (protruding tongue) of each in several male terminal joints 108 that can be connected with female terminal fitting 107 all was projected into socket 126 inside to small part.The opposite side of each male terminal joint 108 is subjected to bending (preferably bending to crank-like through twice) and in the effect of playing leader 141 after positive connector shell 102 is outstanding.Preferably by soldering, welding, crimping, insulation displacement, reflow soldering or the like, corresponding leader 141 will be connected with the conductive path (not shown) of printed circuit board (PCB) 140.Part place at the edge of opening part 126OE of the socket 126 of basic and projection 111 corresponding positive connector shells 102 withdraws from part 142 and preferably basically forms on the whole width of positive connector shell 102.Should be noted that in the present embodiment the edge of opening part 126OE of socket 126 is outstanding slightly forward from the front end of printed circuit board (PCB) 140.
On the other hand; when positive connector shell 102 is connected with female connector housing 101; the edge of opening part 126OE of socket 126 arrives protective bulkhead 105 foremost substantially, and this moment projection 111 a part to the small part of front side be assembled to and withdraw from the part 142.As shown in accompanying drawing 24, the step 111A of the projection 111 of female connector housing 101 (as preferred augmenting portion) preferably has the vertical dimension that equals socket 126 thickness substantially.At step 111A place, female connector housing 107 goes up or goes up at the in-plane that comprises lock part 112 (and deformation direction) in vertical direction (or be not equal to 0 or 180 angle direction, preferably be basically perpendicular to direction of insertion ID) and becomes big or broaden.So when positive connector shell 102 was connected with female connector housing 101, the outer surface of the outer surface of socket 126 and ledge 111 preferably flushed substantially each other.
Next, the function and the effect of present embodiment will be specifically described.Remain under the situation at part latched position (primary importance) the 1P place in the female connector housing 101 at retainer 115, female terminal fitting 107 is inserted in each cavity 106 to small part on direction of insertion ID.Along with female terminal fitting 107 mistakes, lock part 112 is (or on the direction that intersects with direction of insertion ID) strain outwards or downwards, and when female terminal fitting 107 is inserted into when being in the main true the degree of depth, match to the small part elastic return and with the lock hole of the not specified (NS) of female terminal fitting 107 or locking recess or lock part or locking step.Subsequently, when further being pushed into retainer 115 in the female connector housing 101, the top edge of two side plates 122 moves past complete locking projection 125, so that complete locking projection 125 to small part is assembled in the latch recess 123.In this way, retainer 115 keeps or is positioned at complete latched position 2P place.At this complete latched position place, corresponding locking projection 121 matches with the rear end of the rectangular tube portion 109 of corresponding female terminal fitting 107, and excessive deformation prevents that part 116 from contacting with the lower surface of lock part 112 substantially.So locking projection 121 and excessive deformation prevent that part 116 from maintaining female terminal fitting 107 safely.
In this way female terminal fitting 107 is being installed to after operation in the female connector housing 101 finishes, positive connector shell 102 is connected or can connects with female connector housing 101.In other words, when female connector housing 101 to small part assembling or when being inserted in the socket 126 of positive connector shell 102, the lock arm 103 that is arranged on the positive connector shell 102 matches with the mating part of not specified (NS), thereby two connector shells 101,102 are locked to each other together.
In the present embodiment, for the difference in height between the line coupling part of basic and female terminal fitting 107 (preferably bobbin partly, insulated tube) and (rectangle) tubular portion 109 consistent, the outer surface step of female connector housing 101 or be recessed to form projection 111.So, with positive connector shell 102 with after female connector housing 101 is connected, female connector housing 101 can be assembled in the socket 126 to small part in the short part of ledge 111 fronts.So the situation that forms basically identical with the height of female connector housing 101 and bobbin part 110 is compared, and has shortened the height of connector.
In addition, since at positive connector 102 with after negative connector 101 is connected, the part of projection 111 is assembled to withdrawing from the part 142 of socket 126, is assembled to the size that withdraws from the part 142 so the whole length of connector can shorten projection 111 at least.In other words, by shortening length and height, whole connector miniaturization can be kept good operability simultaneously.
Therefore, in order to make the connector miniaturization effectively, have good operability simultaneously, each female terminal fitting 107 all forms and makes the height that (preferably includes bobbin part 110) to the line coupling part from the basal surface height greater than (preferably being rectangle substantially) tubular portion 109.Because the height of each cavity 106 all changes according to this difference in height, institute is so that the outer surface of female connector housing 101 is protruding with bobbin part 110 corresponding parts, thus formation projection 111.On the other hand, withdraw from the part place of edge of opening part 126OE that part 142 is formed on the socket 126 of positive connector shell 102, this part is corresponding with ledge 111, when positive connector shell 102 was connected with female connector housing 101, the part of ledge 111 was assembled to this and withdraws from the part.
And, in the present embodiment, minimizing (shortening its height) in order to allow connector, the lock part 112 in the cavity 106 on outer (descending) layer is at least partially exposed through the outer surface of female connector housing 101.Therefore, if when retainer 115 is positioned at part latched position (primary importance) 1P, external force is applied on the lock part 112, and then female connector housing 101 can't limit the strain of lock part 112.Yet, in the present embodiment, even lock part 112 with excessive deformation, prevents that with the excessive deformation of retainer 115 contacting of part 116 from also can prevent to surpass the strain of elastic limit.So the function of lock part can realize safely.Therefore, in order to shorten height, this structure is extremely important and very favorable.And, be formed on the existing structure by excessive deformation being prevented part 116, promptly on the retainer 115, have the additional effect that does not need to provide the member and the simplified structure that additionally are used to prevent excessive deformation.
Therefore, in order to prevent the excessive strain of lock part, connector is minimized, and improve the operability of connector, one or more lock parts 112 are arranged so that on horizontal (end) surface that is exposed to connector shell 101.Retainer 115 comprises that terminal locking part 120 that can match with one or more female terminal fittings 107 and the excessive deformation that extends substantially forward from this terminal locking part 120 prevent part 116.When retainer 115 is positioned at part latched position (primary importance) 1P place, excessive deformation prevents that part 116 is positioned at below the lock part 112 (perhaps on the deformation direction of lock part 112) or the outside, thereby the guiding end of lock part 112 substantially with or can with excessive deformation prevent part 116 interior (on) surface contacts, even and lock part 112 will strain surpasses its elastic limit, can not further be out of shape.Therefore, can avoid the excessive deformation of lock part 112.
＜the four embodiment 〉
Next, with reference to accompanying drawing 30 and 31 the 4th preferred embodiment of the present invention is described.Along with the miniaturization of female connector housing 101, also attenuation or can attenuation of lock part 112, the latching force that causes locking female terminal fitting 107 reduces.In the 4th embodiment,, preferably strengthen the rigidity of lock part 112 as the precautionary measures.Especially, at least one deep floor or projection 127 form and make (to descend) substantially along the longitudinal that the width centre position (preferably substantially in width central authorities) on surface is outstanding outside each lock parts 112.
On the other hand, the deep floor 127 that need avoid being formed on the lock part 112 disturbs excessive deformation to prevent part 116.In order to realize this purpose, excessive deformation prevents that part 116 is formed with in basic and corresponding deep floor 127 corresponding positions and one or morely withdraws from otch or withdraw from recess or withdraw from step 128.In other words, if when retainer 115 is positioned at part latched position (primary importance) 1P place, strain is carried out in lock part 112, and then the part of deep floor 127 enters maybe can enter and correspondingly cuts 128.And when retainer 115 was positioned at complete latched position (second place) 2P place, (preferably being whole substantially) deep floor 127 was contained in the otch 115, and is preferably not outstanding.
Since in the 4th embodiment by prevent from the part 116 to form otch 128 at excessive deformation, may reduce the intensity that excessive deformation prevents part 116 self, be preferably in and be preferably formed in excessive deformation on the whole substantially width and prevent near the leading edge place of upper surface of part 116 or its so strengthen edge 129.
Owing to can avoid excessive deformation to prevent the distortion of part 116 in a second embodiment, can realize its function effectively so excessive deformation prevents part 116.
Other structures of the 4th embodiment can be basic identical or similar with above-mentioned first and second preferred embodiments.
＜modification embodiment 〉
The present invention not only is confined to embodiment described and illustrated above.For example, following embodiment is also within technical scope of the present invention defined by the claims.Except following embodiment, under the situation that does not break away from the scope of the invention defined by the claims and spirit, can make various variations.
(1) although in the aforementioned embodiment, withdraw from part 142 and form and from the inboard to the outside, penetrate socket 126, by having the form of recess or step part, rather than through hole, projection is withdrawed from.
(2) because under the situation of female connector housing 101 miniaturizations, lock part 112 attenuation are so this can cause the insufficient strength of lock part 112.As the precautionary measures, one or more deep floors (referring to, for example floor 18,20,127) can be formed on the outer surface or lower surface of lock part 112.
(3) under the situation of (2), the excessive deformation of retainer 115 prevents that part 116 can be formed with one or more recesses or through hole, as deep floor withdraw from the hole (referring to, for example part/recess 47,128).Even when retainer 115 is positioned at part latched position (primary importance) 1P place, lock part 112 strains, this also can be avoided deep floor and excessive deformation to prevent the interference of part 116.And, when retainer 115 is positioned at complete latched position (second place) 2P place, also can avoid this interference similarly.
(4) under the situation of (3),, can be formed on the guiding end place that excessive deformation for example prevents part 116 so strengthen the edge because excessive deformation prevents that the intensity of part 116 from reducing.
(5) although in the above-described embodiments, lock part 112 is described as cantilever shape preferably, make that promptly an end portion is supported, another end portion is outstanding on direction of insertion ID substantially, and distortion or deformability on the direction that intersects with direction of insertion ID, but the lock part also can form bridge shape shape (not shown), promptly (for example be subjected to supporting two end portion, at laterally (end) side and antetheca place), and distortion or the deformability on the direction that intersects with direction of insertion ID of the mid portion of lock part.
(6) although in the above-described embodiments, excessive deformation prevents that part 116 preferably has the length of the whole length that equals lock part 112 substantially, if it can realize preventing the function of excessive deformation, does not also need always to have so long length.Even excessive deformation prevents part 116 and has the contacted length in basic side with lock part 112, also can prevent the excessive deformation of lock part 112.
Yet, if in previous embodiment, excessive deformation prevents that part 116 from forming the length with the whole length that equals lock part 112 substantially, owing to can cover lock part 112 to small part, so also can avoid the situation of foreign matter from outer side impaction lock part 112.So if having this length (in previous embodiment), then excessive deformation prevents that part 116 from also playing the effect of the protection part of lock part 112.
(7) in above-mentioned third and fourth embodiment, when retainer 115 is positioned at complete latched position place, excessive deformation prevent part 116 substantially with or can contact with the lower surface of lock part 112, to prevent lock part 112 strain on the direction that unlocks.Yet excessive deformation prevents that part 116 from not needing always to contact with the lower surface of lock part 112.
(8) although in the 4th embodiment, strengthening edge 129 is preferably disposed on the retainer 115, wherein withdraw from otch 128 and be formed on this excessive deformation and prevent in the part 116, but this reinforcement edge 129 also can be arranged on the retainer 115 with otch 128 certainly.
