Each female terminal fitting 12 is configured to roughly have long narrow shape along fore-and-aft direction, for example, by the conductive plate (metallic plate) to one specific (predetermined maybe can the be scheduled to) shape (referring to Fig. 5) that is stamped or cuts into carry out bending, folding and/or embossing obtains.Be formed with a barrel portion 19 (preferably being roughly rectangle or box) that can inject male terminal joint 10 at least in part in the front portion of female terminal fitting 12 (preferably being roughly first half), thereby form a line coupling part (preferably including a cylindrical portion 20) of link to each other with lead 21 (preferably crooked or folding to be connected) a rear portion (preferably being roughly latter half) by crimping.
This cylindrical portion 20 comprise from the opposite side of a substrate (being preferably base plate) of female terminal fitting 12 (about) edge is holded up or projection is one or more, be preferably a pair of crimp, one of them wiring tube 20A preferably is rolled in the front side or is crooked or be folded into the core of lead 21 and link to each other, and insulating cylinder 20B preferably is rolled or bending or be folded into the insulation crust of lead 21 links to each other at rear side.Height or the outstanding length of wiring tube 20A preferably are set as the height that is substantially equal to barrel portion 21, but are lower than or less than the height of insulating cylinder 20B.Like this, go up or holding the holding portion 37A of barrel portion 19 and wiring tube 20A at least in part and be formed with the step part 22 of an inclination at least in part near the intersection between the holding portion 37B of housing insulation tube 20B at the side surface (bottom surface) of vestibule 15.On the other hand, the inner top surface of vestibule 15 (or roughly relative face) all is an equal height in the gamut of holding portion 37A, 37B before and after comprising preferably.
In order to solve the above-mentioned difference in height of female terminal fitting 12, the outer surface of negative connector housing 13 corresponding to the part projection of insulating cylinder 20B, reduces (referring to Fig. 1) roughly simultaneously on corresponding to the part of barrel portion 19.Like this, negative connector housing 13 just is assembled in the room 14 of positive connector housing 11 at least in part corresponding to the part of relatively short barrel portion 19.Therefore, compare with the outer surface of negative connector housing 13 is all made with the situation of insulating cylinder 20B equal height, the height of above-mentioned connector can shorten.
Shown in Fig. 2 to 4, barrel portion 19 is made up of substrate wall (bottom surface) 23, side wall surface 24 and inner top surface 25, wherein substrate wall 23 is roughly narrow and grow, roughly continuously and flush with the substrate (base plate) of cylindrical portion 20 along fore-and-aft direction, side wall surface 24 from substrate wall (bottom surface) 23 opposite sides (about) edge or hold up the marginal portion or projection, inner top surface 25 stretches out from the upper end of a side wall surface 24, and at least in part towards substrate wall (bottom surface) 23.
As illustrated in Figures 5 and 6, a coupling part 26 is arranged to roughly stretch out or be positioned at another sidewall 24 downwards from the rear end of inner top surface 25, and (preferably being roughly plate shape) main spring leaf 27 (at a preferred spring section place) be arranged to roughly along the bottom surface 23 from the coupling part 26 bottom stretch out.
Shown in Fig. 6 and 7, main spring leaf 27 is preferably the cantilever shape of roughly stretching out from the rear portion or the end of barrel portion 19, and its front end is a free end.Roughly say, main spring leaf 27 by a first area P (being preferably about 1/4th) who stretches out forward from the rear end and from first area P stretch out preferred for main spring leaf 27 fore-and-aft direction sizes 1/2nd second area Q and form from the 3rd region R that this second area Q reaches main spring leaf 27 front ends.Main spring leaf is arranged to roughly contact with bottom surface 23 at first area P,, and roughly contacts with bottom surface 23 at the boundary of the second and the 3rd regional Q and R slightly at a distance of certain distance in second area Q place and bottom surface 23.At the 3rd region R place, main spring leaf 27 stretches out obliquely or inwardly forward, and its fore-end is roughly curved or to form obtuse angle oblique down or protruding, thereby constitutes an end or sweep.This end is pressed into upwards heaves, thereby forms a contact portion 28.At the 3rd region R place, the width of main spring leaf 27 forward end gradually narrows down.
Shown in Fig. 3 and 6, the area that roof 25 is positioned at contact portion 28 tops of main spring leaf 27 also is pressed into one (preferably being roughly rectangle) or the part that caves inward downwards, it is as a pressure receiving unit 29, to guarantee a forming contact pressure between contact portion 28 and male terminal joint 10.Distance between pressure receiving unit 29 and roughly relative contact portion 28 (in not case of bending or nature) preferably is set as less than the thickness that inserts the male terminal joint in it at least in part.In addition, be provided with at pressure receiving unit 29 rears one can with the lockhole 35 of above-mentioned lock part 17 engagements, with clamping female terminal fitting 12.
The mid portion of substrate wall (bottom surface) 23 (preferred substantial middle part) partly is cut into or is curved one (preferred essentially rectangular and/or cantilever shape) and roughly stretched out (referring to Fig. 5) rebound leaf of the spring 30 (as a preferred spring section) obliquely or inwardly forward, and wherein the rebound leaf of the spring 30 is exposed at outside the outer surface (bottom surface) of barrel portion 19.This rebound leaf of the spring 30 extends along the lower surface (outer surface) of the 3rd region R of main spring leaf 27 at least in part, preferably with 27 one-tenths identical angles of main spring leaf, and/or above a half-distance of the 3rd region R total length.The front end of this rebound leaf of the spring 30 is set as the summary slightly-inclined rear in the contact portion 28 of main spring leaf 27.
There are certain distance in strain not and in the raw the time each other in the main spring leaf 27 and the rebound leaf of the spring 30.Yet during downward or outside strain, the lower surface of main spring leaf 27 or outer surface are from the top or inboard contact at least in part rebound leaf of the spring 30 front ends (referring to Fig. 2 and Fig. 8) in the raw when main spring leaf 27.
The bottom part of the rebound leaf of the spring 30 and/or the part by the bottom are pressed into upwards or inwardly swells, thereby forms a bump 31 (as a preferred reinforcing section).This bump 31 has increased the rigidity (referring to Fig. 7 and 9) of the rebound leaf of the spring 30.This bump 31 preferably has the shape (a water droplet shape is more specifically said so) of a circular.When main spring leaf 27 and the rebound leaf of the spring 30 all were in the nature that strain does not take place, bump 31 had certain distance with main spring leaf 27.
The rebound leaf of the spring 30 has one or more a pair of rectangle catch 32 that are preferably, and it outwards crosses out from the same level of (preferably its front end) lateral edges (left and right edges).On the other hand, by forming this rebound leaf of the spring 30 and catch 32, on substrate wall (bottom surface) 23, leave an opening, the part of this edge of opening be positioned at bottom surface 23 and (about) intersection between the sidewall 24, as a pair of roughly with catch 32 corresponding (about) side joint receiving portions 33.When the rebound leaf of the spring 30 was in the nature of strain not, this catch 32 was positioned at the below or the outside of this side joint receiving portions 33, but it roughly contacts with receiving unit 33 during (outside) promotion from the below when foreign object.Can prevent that like this rebound leaf of the spring 30 from making progress excessively or inside (towards main spring leaf) strain.It should be noted that catch 32 is not from sidewall 24 protuberance of barrel portion 19, as shown in Figure 8.
As shown in Figure 7 and Figure 8, before substrate wall (bottom surface) 23 is positioned at the rebound leaf of the spring 30 and on the part below main spring leaf 27 front ends, be formed with (preferably being roughly a rectangle) opening, as an outlet, when avoiding downward or outside strain at main spring leaf 27 and the front end of main spring leaf 27 interfere.Substrate wall (bottom surface) 23 roughly prevents part 36 corresponding to an area of the contact portion 28 of main spring leaf 27 as an excessive deformation, thus during by or outside strain downward at main spring leaf 27 roughly from below or the outside contact with the lower surface of main spring leaf 27 and prevent the undue strain of main spring leaf.
Below, introduce function and the effect of this embodiment.
Female terminal fitting 12 is inserted in the vestibule 15 of negative connector housing 13 at least in part.Then, lock part 17 is meshed to maintain female terminal fitting 12 with lockhole 35.At this moment, the barrel portion 19 of female terminal fitting 12 and wiring tube 20A are contained in before the step part 22 of vestibule 15 at least in part, and insulating cylinder 20B is contained in after the step part 22 at least in part.
After in one or more female terminal fittings 12 are contained in corresponding one or more vestibule 15 at least in part, retainer 18 preferably laterally or from the below is installed, and to mesh with the rear end of barrel portion 19, can not drop out thereby female terminal fitting 12 is pinned.
Next, this negative connector housing 13 installs to the positive connector housing 11 ground rooms 14 from engage side or from the place ahead at least in part.When connecting, the insertion mouth 16 that male terminal joint 10 passes negative connector housing 13 at least in part enters in the barrel portion 19.Along with the carrying out of further connection, male terminal joint 10 roughly contacts with the contact portion 28 of main spring leaf 27, thereby downwards or to external pressure main spring leaf 27 or make main spring leaf 27 distortion.Then, main spring leaf 27 downward or outside strains, thereby from the inboard or the top roughly contact with the front end of the rebound leaf of the spring 30.In this way, the rebound leaf of the spring 30 is by downwards or to external pressure, thus downward or outside strain.Therefore, the resilient force of the main spring leaf 27 and the rebound leaf of the spring 30 is on male terminal joint 10, thereby male terminal joint 10 is squeezed between the contact portion 28 of barrel portion 19 and main spring leaf 27, is electrically connected to form.
At this moment, owing to bump 31 preferably is located on the bottom of each rebound leaf of the spring 30 by compacting or reinforcement (for example by the wall portion that a thickening is set, one or more reinforcement projection or similar structures), thereby the rigidity of the rebound leaf of the spring 30 is strengthened.In this way, strengthen main spring leaf 27, acted on the elastic force of male terminal joint 10 with increase.Therefore, can guarantee a higher contact pressure for each male terminal joint 10.
In addition, owing to bump 31 preferably can form by a kind of method of simply suppressing in the bottom of the rebound leaf of the spring 30, so be easy to strengthen the rebound leaf of the spring 30.
After the connection of finishing two connector shells 11,13, two connector shells 11,13 keep connection status by a not shown still known locking mechanism.
According to this embodiment, the outer surface of negative connector housing 13 is provided in roughly on the part corresponding to insulating cylinder 20B higher or wideer or have a bigger extended length, on the contrary shorter or narrower or have a less extended length on part roughly corresponding to barrel portion 19, thus adapt with difference in height with each female terminal fitting 12.Like this, negative connector housing 13 is mounted to or is assembled at least in part in the room 14 of positive connector housing 11 corresponding to the part of relatively short barrel portion 19, thereby make with the situation of insulating cylinder 20B equal height with the outer surface of the sort of reinforcing yin essence connector shell 13 and to compare, such scheme can reduce the height of connector.
Yet, according to said structure, intersection between the holding portion 37B of holding portion 37A that holds barrel portion 19 and wiring tube 20A and housing insulation tube 20B, ledge structure 22 is necessary.Like this, if when the operator inserts this female terminal fitting because of carelessness with vertical rightabout, bottom surface 23 can roughly contact with step part 22.Then because the rebound leaf of the spring 30 is exposed to outside the bottom surface 23, so the rebound leaf of the spring 30 roughly contacts with step part 22 probably in the direction generation strain of pushing upwards.
Therefore, in this embodiment, the rebound leaf of the spring 30 preferably has one or more catch 32, this catch roughly from the below or the outside contact with the receiving unit 33 of barrel portion 19.Like this, can prevent the excessive strain of the rebound leaf of the spring 30.
Use can reduce the height of negative connector housing 13 effectively according to the female terminal fitting 12 of this embodiment.
Because the marginal portion that can stay opening when forming the rebound leaf of the spring 30 by cutting or bending on barrel portion 19 forms receiving unit 33 with as receiving unit 33 thereby need not new step.
Therefore, in order to provide one can prevent the clamped nipple of the excessive strain of spring section and the connector that uses this clamped nipple, in a female terminal fitting 12, the rebound leaf of the spring 30 that (preferred general cantilever shape) main spring leaf 27 that roughly extends forward and roughly extend before the lateral of this main spring leaf 27 be arranged on the barrel portion 19 that holds male terminal joint 10 at least in part or within.In order to prevent that the rebound leaf of the spring 30 makes progress or moves inward when pushing away the free end of the rebound leaf of the spring 30 from the lateral, thereby be provided with one or more catch 32 from the rebound leaf of the spring 30 roughly corresponding to two opposite sides or the lateral parts upper process of Width, simultaneously by cutting or the crooked edge of opening that on barrel portion 19, stays when forming the rebound leaf of the spring 30 as one or more receiving units 33 that can roughly contact with catch 32.Like this, even there is foreign object to bump against the rebound leaf of the spring 30, this rebound leaf of the spring 30 also can prevent excessive deformation on the direction that upwards pushes away.
