And a pair of soldering pin 30 is installed on the Width both ends of housing 10.A pair of soldering pin 30 be included in the soldering pin 30 in the left side shown in the Fig. 8 Width left part of housing 10 installing and Fig. 9 of installing in the Width right part of housing 10 shown in the soldering pin 30 on right side.Two soldering pins are formed as Mirror Symmetry shape, and basic comprising is identical.Thereby, formation and the shape of the soldering pin 30 on right side are only described.
Each soldering pin 30 on right side is for housing 10 solderings being fixed on to the parts on circuit substrate PCB (with reference to Figure 10 (A), (B)), by metallic plate being carried out to stamping-out and bending machining forms.Each soldering pin 30 possesses flat base portion 31, the portion that is pressed into 32 of forwards extending from the leading edge of base portion 31 of extending along fore-and-aft direction and the substrate fixed part 33 of giving prominence to from being pressed into the lower edge of portion 32 downwards.As shown in Fig. 7 (A), be pressed into portion 32 and be pressed into from the rear of housing 10 in being pressed into in opening 15, soldering pin 30 is fixed on housing 10 thus.In addition, it is upper that circuit substrate PCB is fixed in 33 solderings of substrate fixed part, and housing 10 is fixed on circuit substrate PCB thus.
In addition, as shown in Fig. 1 and Fig. 9, each soldering pin 30 possesses the upper limb housing rib 34 of (situation of the soldering pin 30 in left side is right side) bending to the left from base portion 31.Housing rib 34 is positioned on the sidewall 10d of housing 10 and the upper surface of the second upper wall 10c, to strengthen housing 10.
And as shown in Figure 9, each soldering pin 30 possesses from the rear end of base portion 31 and bends to the inside, and and then the reflex part 35 that turns back towards front, possess the latch arms 37 of forwards extending from the front end bottom of this reflex part 35.As shown in Fig. 7 (B), the first resettlement section 14a that latch arms 37 is accommodated slit 14 from latch arms extends to the second resettlement section 14b, and is provided with to the interior outstanding latch boss 37a of cable holding opening 11 at front end.Latch arms 37 forms in mode that can strain, and as shown in Figure 10 (B), latch boss 37a engages to prevent coming off of FPC with the otch 42 that inserts the FPC40 in cable holding opening 11.
In addition, as shown in Fig. 7 (B), each soldering pin 30 possesses the housing fixed part 36 forwards extending from the upper front end of reflex part 35.Housing fixed part 36 comprises from forwards two forked downside supporting pieces 36a and upside supporting pieces 36b that extend of the upper front end of reflex part 35.Downside supporting pieces 36a and upside supporting pieces 36b clamp the second upper wall 10c to be fixed on housing 10 from the rear of housing 10 between them.Thus, ensure the recovery of the latch arms 37 of strain in the time that FPC40 insertion cable holding opening 11 is interior.
Then FPC40 is inserted the effect when interior of the cable holding opening 11 of electric connector 1 by the mode that the conductor portion 41 that, illustrates to be located at one side 40a with reference to Figure 10 (A), (B) becomes table side.
As shown in Figure 10 (A), if become the mode of table side to be located at the conductor portion 41 of one side 40a, FPC40 is inserted in cable holding opening 11 to the conductor portion 41 of the upper side contacts teat 23a Elastic Contact FPC of the upper elastic arm 23 of contact 20.Thus, the conductor portion 41 of FPC40 is electrically connected on the conductive pattern on circuit substrate PCB via contact 20.Now, the inboard of the lower side contacts teat 22a contact FPC40 of the lower elastic arm 22 of contact 20.Thereby FPC utilizes elastic force separately and is held between upper elastic arm 23 and lower elastic arm 22.
So, in the time that FPC40 insertion cable holding opening 11 is interior, the conductor portion 41 of the upper side contacts teat 23a Elastic Contact FPC40 of upside elastic arm 23.Therefore, do not need, for making contact 20 contact the actuator of the conductor portion 41 of FPC40, can realize low level.In addition, owing to not needing actuator, therefore can also cut down parts number of packages, can seek cost degradation.
And, if FPC40 inserts in cable holding opening 11, as shown in Figure 10 (B), be located at the latch boss 37a of latch arms 37 of soldering pin 30 and the otch of FPC40 42 and engage to carry out the anticreep of FPC40.,, if FPC40 advances in cable holding opening 11, the top of FPC40 is connected to latch boss 37a.If FPC40 is advanced further, latch boss 37a moves into the inboard of FPC40, and latch arms 37 is with the mode strain downwards along surface in FPC40.If FPC40 is advanced further,, in the time that latch boss 37a comes the position of otch 42 of FPC40, latch arms 37 is restored, and latch boss 37a is moved upward and is sticked in otch 42.Thus, prevent that FPC40 from coming off.So, owing to utilizing latch arms 37 to carry out the anticreep of FPC40, therefore can carry out reliably the anticreep of FPC40.If there is no latch arms 37, FPC40 is only clamped by the elastic force separately between upper elastic arm 23 and lower elastic arm 22, likely deviates from from cable holding opening 11.On the other hand, if improve the chucking power going up between elastic arm 23 and lower elastic arm 22 to seek the anticreep of FPC40,, in the time that FPC40 inserts to cable holding opening 11, insertion force uprises, and the insertion of FPC40 becomes difficulty.
At this, because latch arms 37 forms in mode that can strain, therefore latch boss 37a is sticked in the otch 42 of FPC40 reliably, can carry out reliably the anticreep of FPC40.
In addition, soldering pin 30 possesses housing fixed part 36, and housing fixed part 36 is fixed on the second upper wall 10c of housing 10, ensures the recovery of the latch arms 37 of strain in the time that FPC40 insertion cable holding opening 11 is interior.Therefore, the latch boss 37a of latch arms 37 engages reliably with the otch of FPC40 42, can carry out reliably the anticreep of FPC40.If there is no housing fixed part 36, in the time that FPC40 insertion cable holding opening 11 is interior, the latch arms 37 of strain likely can not be restored to original position downwards.
And cable holding opening 11 is allowed the oblique insertion of FPC40.And, if the top ends of FPC40 insert in cable holding opening 11, by protuberance 12, the part being connected with the top ends of inserting in cable holding opening 11 along with leaving from housing 10 to oblique top orientation.Therefore, it is large that the space between FPC40 and circuit substrate PCB becomes, and electronic unit (not shown) can be installed on to this space on circuit substrate PCB.Thus, in the time that electric connector 1 is arranged on circuit substrate PCB, electric connector 1 can be installed on to the part beyond ora terminalis on circuit substrate PCB.
In addition, possess housing rib 34 for the soldering pin 30 that housing 10 solderings is fixed on to circuit substrate PCB, housing rib 34 is positioned on the upper surface of the second upper wall 10c of housing 10 to strengthen housing 10.Therefore, even if the FPC40 being contained in the cable holding opening 11 of housing 10 shakes upward, also can prevent housing 10, the particularly excessive deformation of the first upper wall 10b and the second upper wall 10c.Thus, can prevent the excessive deformation of contact 20.If there is no housing rib 34,, in the time that FPC40 is shaken upward, be positioned at the first upper wall 10b and the likely exceedingly distortion of the second upper wall 10c of the FPC40 upside that is contained in cable holding opening 11.This be because, the first upper wall 10b and the second upper wall 10c form in order to realize the low level of electric connector 1 thin-walled, thus mechanical strength a little less than.If the FPC40 being contained in the cable holding opening 11 of housing 10 is shaken upward, also displacement upward of the upper elastic arm 23 of the contact 20 in this FPC40 upside.As shown in Figure 10 (A), upper elastic arm 23 is located in the upper elastic arm resettlement section 13c of the first upper wall 10b formation of housing 10.Therefore, at upper elastic arm 23, upward when displacement, the first upper wall 10b becomes the retainer of the excessive deformation that prevents elastic arm 23.But if the first upper wall 10b is out of shape because FPC shakes exceedingly upward, its function as retainer dies down, thereby can not prevent the excessive deformation of elastic arm 23.Thereby, by being set at soldering pin 30, housing rib 34 prevents in the time that FPC40 is shaken upward housing 10, particularly the excessive deformation of the first upper wall 10b and the second upper wall 10c is important.
Above, execution mode of the present utility model is illustrated, but the utility model is not limited thereto, can carries out various changes, improvement.
For example, be connected in the example of electric connector 1 as flat shape cable although the description of FPC40, but can also make FFC (Flexible Flat Cable) be connected in electric connector 1.
In addition, housing rib 34 loads on the upper surface of housing 10, is not limited to be positioned in the situation on the upper surface of sidewall 10d and the second upper wall 10c.
In addition, not necessarily need to latch arms 37 be set at soldering pin 30.
And, not necessarily need to housing fixed part 36 be set at soldering pin 30.
In addition, as the elastic arm contacting with the conductor portion 41 of being located at FPC40, the situation that comprises elastic arm 23 and lower elastic arm 22 is described, but can has been also the either party who comprises in elastic arm 23 or lower elastic arm 22.
