In addition, the auxiliary section 43 of lid 4 is not limited to match with stiffener 3, also can be the structure that other parts (for example, housing 2) with electric connector 1 match.
On housing 2, relatively maintain a plurality of terminals 5,6 (for example, adding up to 35) with peristome, these a plurality of terminals be inserted into the crimping and realize being electrically connected of this flat flexible cable and wiring substrate mutually of the flat flexible cable that inserts in the space 27.Each terminal 5,6 is for example made by the punch process of metallic plate.A plurality of terminals 5,6 for example, configured in parallel (with reference to Fig. 1 (a)) (for example, about 0.3mm spacing) uniformly-spaced in vertical view, on left and right directions.
In this embodiment, a plurality of terminals 5,6 for example comprise two kinds of the 1st terminal 5 that is pressed into housing 2 from the place ahead and the 2nd terminals 6 that is pressed into housing 2 from the rear etc., and these the 1st and the 2nd terminals 5,6 are along the mutual alternate configurations of left and right directions.
But, the 1st terminal 5 and the 2nd terminal 6 direction that is pressed on housing 2 is not limited to aforesaid direction, also can be that the 1st terminal 5 is pressed into housing 2 from the rear, the 2nd terminal 6 is pressed into the structure of housing 2 from the place ahead, also can be the structure that the 1st terminal 5 and the 2nd terminal 6 are pressed into from equidirectional (the place ahead or rear).
Fig. 2 and Fig. 3 are the cutaway views along the A-A line of Fig. 1 (c).In addition, Fig. 4 and Fig. 5 are the cutaway views along the B-B line of Fig. 1 (c).
With reference to Fig. 2～Fig. 5, each terminal (the 2nd terminal 6 shown in the 1st terminal 5 shown in Fig. 2,3 and Fig. 4,5), its leading section (leading section of operation strip portion 53,63) stretches out to the place ahead of the upper plate portion 21 of housing (lid 4 sides).In the back end edge of lid 4, be formed with depression 44 with the corresponding position of leading section of each terminal 5,6, this depression 44 is used to prevent the leading section interference of lid 4 and each terminal 5,6 when opening and closing.
In depression 44, be formed with the receiving portion 45 of the cam face that for example has section substantially elliptical shape, under the state of closing lid 4, each extends the major axis of the oval section of receiving portion 45 along front and back.And close under the state (Fig. 2 (a) and Fig. 4 (a)) of lid 4 flat flexible cable 7 not being inserted in the housings 2, the leading section of each terminal 5,6 following non-contactly with corresponding receiving portion 45 top relative to, under this state, applied stress not on each terminal 5,6.But the shape of receiving portion 45 is not limited to section substantially elliptical shape, also can be other cam face.
When state shown in Fig. 2 (a) and Fig. 4 (a) is opened lid 4, the receiving portion 45 that terminal 5,6 is rotated boosts, and forms and the equal above insertion space 27 (with reference to Fig. 2 (b) and Fig. 4 (b)) highly of the thickness of flat flexible cable 7 at the crimping position of terminal 5,6.Insert space 27 by this, flat flexible cable 7 can be inserted to the inside of terminal 5,6.Such electric connector 1 is the connector that can zero insertion force inserts so-called ZIF (ZeroInsertion Force) type of flat flexible cable.
Then, with reference to Fig. 2 and Fig. 3, the action form along with the 1st terminal 5 of the insertion of the switching of lid 4 and flat flexible cable 7 is described.Fig. 2 (a) expression is not inserted flat flexible cable 7 and is closed the state of lid 4, and the state of lid 4 is opened in Fig. 2 (b) expression from the state of Fig. 2 (a).In addition, the state that lid 4 is opened in Fig. 3 (a) expression inserts the state of flat flexible cable 7 down, and Fig. 3 (b) expression is closed the state of lid 4, the state that Fig. 3 (c) expression is rearward slided lid 4 from the state of Fig. 3 (a).
The 1st terminal 5 for example has along stator portion 51 that the fore-and-aft direction of the bottom of the inner space 24 of housing 2 extends, from the rearward end of this stator portion 51 strain portion 52 outstanding upward and a lateral bending curved shape forwards, and the setting and extend to the operation strip portion 53 in the place ahead of upper plate portion 21 of linking to each other with strain portion 52.Leading section in stator portion 51 is formed with downwards (wiring substrate 8 one sides) outstanding wire portion 54, and carries out soldering by the docking section of the terminal pad portion on the fitting surface of this wire portion 54 and wiring substrate 8, and by leg coat these docking sections around.In view of the above, the 1st terminal 5 is fixed on the wiring substrate 8, and these the 1st connectors 5 are connected electrically on the wiring substrate 8.
In addition, the rearward end in stator portion 51 is formed with the rearward outstanding portion that is pressed into 55, and is pressed into being pressed in the hole 28 of housing 2 formation by will be pressed into portion 55 from the place ahead, and the 1st terminal 5 is fixed on the housing 2.Limit, upper end being pressed into portion 55 for example is formed with snap projection 551, and the portion that is pressed into 55 that this snap projection 551 is used for being pressed into hole 28 from the place ahead is buckled in and is pressed in the hole 28.
For example being extruded with from the top (what is called, upper contact type) downwards from the central portion of operation strip portion 53 is crimped on and is inserted into the contact site 56 that inserts the flat flexible cable 7 in the space 27.In addition, the central portion in stator portion 51 is formed with outstanding upward pressurization part 511 in the forward slightly position with contact site 56 subtend positions.And, leading section (rear side of receiving portion 45) in operation strip portion 53, the limited position of outstanding downwards formation portion 57, this limiting section 57 can not rearward limit receiving portion 45 with lid 4 down movably at the state that does not insert flat flexible cable 7 (state of Fig. 2 (a)).
Shown in Fig. 2 (a), flat flexible cable 7 is not inserted in the housings 2 and close under the state of lid 4, even lid 4 is rearward slided, also limit the receiving portion 45 of sliding along interface 58 by the front (slip restriction face 571) of limiting section 57, can not further rearward slide.When the state of Fig. 2 (a) is opened lid 4, receiving portion 45 is rotated (with reference to Fig. 2 (b)) along with the rotation of lid 4.Because receiving portion 45 has the roughly oval cam face of section, so boost the leading section of operation strip portion 53 along with the rotation of receiving portion 45.Thus, in (between contact site 56 and the pressurization part 511) between operation strip portion 53 and the stator portion 51, the insertion space 27 of the height more than the thickness of formation and flat flexible cable 7 is equal.
Shown in Fig. 2 (b), under the state of at utmost opening lid 4, because following (interface 58) of the leading section of section of receiving portion 45 vertical (long axis direction of oval section) and operation strip portion 53 be quadrature roughly, so, on the direction (direction that lid 4 is closed) of these receiving portion 45 rotations, can not play a role from by the power of the interface 58 of the operation strip portion 53 of the application of force downwards to receiving portion 45 effects.Thereby, when at utmost opening lid 4, can maintain the state shown in Fig. 2 (b).
Then, shown in Fig. 3 (a), from the place ahead of electric connector 1 to flat flexible cable 7 is inserted spaces 27, and when lid 4 is forwards rotated, by acting on the spring force in the operation strip portion 53, and, become lid 4 closing state (with reference to Fig. 3 (b)) from interface 58 along the directive effect power that makes receiving portion 45 rotations.Under this state, the front end of the contact site 56 of operation strip portion 53 is crimped on the flat flexible cable 7 from the top.Meanwhile, pressurization part 511 is pressurizeed to flat flexible cable 7 upward in the forward slightly position of crimping position, therefore, flat flexible cable 7 is clamped on the 1st terminal 5 securely, realizes the electrical connection between them.
Under the state shown in Fig. 3 (b), because contact site 56 is crimped on the flat flexible cable 7, so become the state of amount that 53 risings of operation strip portion are equivalent to the thickness of flat flexible cable 7.In view of the above, form the space 46 of the height that enough receiving portions 45 pass through at limiting section 57 and between above the flat flexible cable 7, when state shown in Fig. 3 (b) rearward slides lid 4, become the state (with reference to Fig. 3 (c)) in the space 46 that below that receiving portion 45 is positioned at limiting section 57 forms.
Under the state shown in Fig. 3 (c), even will open lid 4, the back end edge of lid 4 arrive to flat flexible cable 7 above, be against above the receiving portion 45 on following (the limit rotation face 572) of limiting section 57, therefore, receiving portion 45 rotations can not be made, lid 4 can not be opened.
According to this execution mode, only on the 1st terminal 5, limiting section 57 is set, just can make lid 4 slide, limiting section 57 is matched with the receiving portion 45 of lid 4, and the rotation of restriction receiving portion 45 can be locked in closed condition to lid 4.Thereby, can lid 4 be locked in closed condition with better simply formation.
In addition, under the state (Fig. 2 (a) and state (b)) that flat flexible cable 7 is not inserted in the housing 2,45 limited 57 restrictions of receiving portion, lid 4 can not rearward move, and therefore, lid 4 can be maintained the state that can open and close.Thereby, under situation about flat flexible cable 7 being inserted in the housing 2, only open lid 4 and just can form insertion space 27, therefore flat flexible cable 7 easily is installed.
Because under the state that flat flexible cable 7 is not inserted in the space 27, lid 4 is slided, so can not lock this lid 4.But, under this state, by relative with receiving portion 45 to a plurality of terminals 5,6 on limit these receiving portions 45, and lid 4 is maintained closed condition.Thereby, open and close easily because can prevent lid 4, so can prevent when the manufacturing of this electric connector 1 or the medium lid 4 of handling process is not intended to open and damaged.
In this embodiment, the structure that has slip restriction face 571 and limit rotation face 572 on identical parts (limiting section 57) is described, but also can be the formation that on different parts, is provided with respectively.
Secondly, with reference to Fig. 4 and Fig. 5, the action form of the 2nd terminal 6 along with the insertion of the switching of lid 4 and flat flexible cable 7 described.Fig. 4 (a) expression is not inserted flat flexible cable 7 and is closed the state of lid 4, and the state of lid 4 is opened in Fig. 4 (b) expression from the state of Fig. 4 (a).The state that lid 4 is opened in Fig. 5 (a) expression inserts the state of flat flexible cable 7 down, and Fig. 5 (b) expression is closed the state of lid 4, the state that Fig. 5 (c) expression is rearward slided lid 4 from the state of Fig. 5 (a).
The 2nd terminal 6, for example, have the portion that is pressed into 65 of the rearward end, its height of the inner space 24 that is configured in housing 2 and the roughly consistent essentially rectangular of the height of inner space 24, with the bottom front end that is pressed into portion 65 from this stator portion 61 that forwards extend 24 bottom along the inner space, reach the operation strip portion 63 that extends to the place ahead of upper plate portion 21 from the front end of the upper end that is pressed into portion 65 by strain portion 62.By the 2nd terminal 6 being inserted into the inner space 24 of housing 2 from the rear, be pressed in the housing 2 and will be pressed into portion 65, the 2nd terminal 6 is fixed on the housing 2.For example form snap projection 651 on the limit, lower end that is pressed into portion 65, the portion that is pressed into 65 that this snap projection 651 will be pressed into the 2nd terminal 6 of inner space 24 from the rear is buckled on the inner face of housing 2.
In the rear end lower that is pressed into portion 65, be formed with (wiring substrate 8 one sides) outstanding wire portion 64 downwards, and carry out soldering by the docking section of the terminal pad portion on the fitting surface of this wire portion 64 and wiring substrate 8, and by leg coat these docking sections around.Thus, the 2nd terminal 6 is fixed on the wiring substrate 8, and these the 2nd terminals 6 are connected electrically on the wiring substrate 8.
In this embodiment, the wire portion 54 of the 1st terminal 5 is outstanding downwards from the leading section of housing 2, the wire portion 64 of the 2nd terminal 6 is outstanding from the rearward end of housing 2, therefore, under the situation of this electric connector 1 of beneath, the wire portion 54,64 of each terminal 5,6 is staggered arrangement (reaching (c) with reference to Fig. 1 (b)) along left and right directions.In view of the above, even under the narrow situation in the interval of the 1st terminal 5 and the 2nd terminal 6 (spacing), also can fully guarantee to be used for each wire portion 54,64 space that soldering is used on wiring substrate 8, interfere the generation situation of short circuit mutually so can prevent to be formed on each wire portion 54,64 leg on every side, and improve the assembling height.
The leading section of operation strip portion 63, for example be to comprise that above-below direction roughly extends and be crimped on the contact site 66 of (what is called, the upper contact type) on the flat flexible cable 7 that inserts the space 27 from the top and the shape of roughly " L " word shape of forwards outstanding from the upper end of contact site 66, as to constitute the interface 68 that connects with receiving portion 45 below it docking section 67.In addition, the leading section of stator portion 61, relative with contact site 66 to the forward slightly position of position be formed with outstanding upward pressurization part 611.
Shown in Fig. 4 (a), when the state of closing lid 4 never flat flexible cable 7 being inserted in the housings 2 was opened lid 4, receiving portion 45 was rotated (with reference to Fig. 4 (b)) along with the rotation of lid 4.Because receiving portion 45 has the roughly oval cam face of section, so boost the leading section of operation strip portion 63 along with the rotation of receiving portion 45.In view of the above, the insertion space 27 of the height more than (between contact site 66 and the pressurization part 611) formation between operation strip portion 63 and the stator portion 61 and the thickness of flat flexible cable 7 are equal.
Shown in Fig. 4 (b), under the state of at utmost opening lid 4, following (interface 68) of the leading section of section of receiving portion 45 vertical (long axis direction of oval section) and operation strip portion 63 be quadrature roughly.Thereby,, can on these receiving portion 45 direction of rotation (direction that lid 4 is closed), not play a role from acted on the power of receiving portion 45 by the interface 68 of the operation strip portion 63 of the application of force downwards.Thereby, when at utmost opening lid 4, can maintain the state shown in Fig. 4 (b).
Then, shown in Fig. 5 (a), in the place ahead flat flexible cable 7 is inserted space 27 from electric connector 1, when lid 4 is forwards rotated, by acting on the spring force in the operation strip portion 63, make the directive effect power of receiving portion 45 rotations from interface 68 edges, and lid 4 becomes closed condition (with reference to Fig. 5 (b)).Under this state, the front end of the contact site 66 of operation strip portion 63 is crimped on the flat flexible cable 7 from the top.Meanwhile, the flat flexible cable 7 because pressurization part 611 is pressurizeed on the forward slightly position of crimping position upward so flat flexible cable 7 is clamped on the 2nd terminal 6 securely, is realized the electrical connection between them.
When the state shown in Fig. 5 (b) rearward slides lid 4 (with reference to Fig. 5 (c)), receiving portion 45 is docked with the front (slip restriction face 661) of contact site 66, and lid 4 can not further rearward be moved.At this moment, at the 1st terminal 5, limiting section 57 is positioned at the top of receiving portion 45.
On the other hand, when taking off the flat flexible cable that is connected with this electric connector 1, as long as the form opposite with above-mentioned form makes lid 4 displacements.Promptly, make lid 4 displacement forwards, become the state that can open and close lid 4, then, by opening lid 4, the the 1st and the 2nd terminal 5,6 is risen, remove the crimping of each terminal 5,6 relative flat flexible cable 7, forwards pull out flat flexible cable 7, then can take off flat flexible cable 7 from electric connector 1.
Fig. 6 is the stereogram of surface structure of the electric connector 101 of expression another embodiment of the present invention.In addition, Fig. 7 is the vertical view of the electric connector 101 of Fig. 6.But, in Fig. 7, omitted the pars intermedia of the left and right directions of electric connector 101 and represented.
This electric connector 101, for example the electric connector 1 with the 1st execution mode is identical, be to be used for flat flexible cables 7 such as FPC are connected electrically in electric connector on the wiring substrate 8, and be the electric connector 101 that can flat flexible cable 7 be inserted the so-called ZIF type in the spaces 27 with zero insertion force.The difference of the electric connector 1 of this electric connector 101 and the 1st execution mode only is the cooperation position of lid 4 and stiffener 3, and therefore, other structure is used prosign in the drawings, and omits its explanation.
In the bottom of the left and right sides of lid 4 both ends of the surface, for example give prominence to formation auxiliary section 47 from its central portion to front end to the side.In addition, the leading section on the top of the main part 32 of each stiffener 3 for example forms to be roughly the protuberance 37 that " V " word shape (for example about 0.13mm) is bent to form to peristome 26 1 side-prominent modes.Opening lid 4, insert flat flexible cable 7 in the housings 2 via peristome 26 after, if rear (direction of insertion D) is closed and be pressed into to lid 4, then each auxiliary section 47 of lid 4 is along the slid underneath of the protuberance 37 of corresponding stiffener 3.And under the state that lid 4 is pressed into rear side (latched position), for example the rearward end of auxiliary section 47 (for example about 0.3mm) overlaps up and down with protuberance 37 in vertical view.
According to above-mentioned formation, under the state that lid 4 is pressed into rear side,, open so can prevent lid 4 reliably because limit its auxiliary section 47 by the protuberance 37 of each stiffener 3.Especially, stiffener 3 is securely fixed on the wiring substrate 8 by soldering, and the auxiliary section 47 that therefore can stably limit lid 4 can prevent more reliably that lid 4 from opening.
On the top of the fore-and-aft direction central portion of the left and right sides of lid 4 both ends of the surface, for example overlook the restrictions 48 that is the general triangular shape to outstanding being formed with in side.As Figure 6 and Figure 7, lid 4 be in by in face of under the state of side, form the state that docks by the face of side in front of the protuberance 37 of restrictions 48 and stiffener 3.If rearward be pressed into lid 4, then push protuberance 37 laterally, stiffener 3 strains by restrictions 48 from this state.And if further rearward push lid 4, then restrictions 48 is crossed the rear side that protuberance 37 moves to protuberance 37.Under this state, stiffener 3 is returned to original state, and protuberance 37 is stuck in and limits lid 4 on the restrictions 48 to by side (latch-release direction) slip in front, therefore, makes it displacement if lid 4 is not applied external force, then can not be to sliding by this side one front side.
This electric connector 101, identical with the electric connector 1 of the 1st execution mode, can be positioned at lid 4 and open lid 4 during side in face of relying on most, still, when being positioned at the most inboard (latched position), lid 4 can not open lid 4.As mentioned above, lid 4 is being pressed under the most inboard state, is making it displacement if lid 4 is not applied external force, then can not be to side slip in front.Like this, can prevent: the use at this electric connector 101 is medium, because vibration etc., lid 4 is not intended to side slip in front, and lid 4 is opened, the problem that the flat flexible cable breaks away from.
Especially because by with fixedly secure cooperating of stiffener on wiring substrate 8, can stablize restriction lid 4 in face of side slide, open so can prevent lid 4 more reliably.
In addition, not only can lock the switching of lid 4, and can therefore, can improve the sensation of finishing of cable fitting operation by the slip of restrictions 48 restriction lids 4 in latched position.
But, be not limited in by limiting from cooperating of the protuberance 37 of the outstanding auxiliary section 47 of lid 4 and stiffener 3 that lid 4 is opened or by the structure that limits lid 4 slips that cooperates from the protuberance 37 of the outstanding restrictions 48 of lid 4 and stiffener 3, for example, also can be by the cooperating of protuberance that forms on the side in lid 4 and stiffener 3 and the recess that on the opposing party, forms, and limit the switching of lid 4 or the structure of slip.
In addition, be not limited to lid 4 auxiliary section 47 or restrictions 48, match with stiffener 3, also can be other parts (for example, housing 2) with electric connector 1 such structure that matches.
The present invention is not limited to the content of above execution mode, can carry out various changes in the scope of purport record of the present invention.
For example, under the state that flat flexible cable 7 is not inserted spaces 27, prevent the locking mechanism that prevents that lid 4 from opening in latched position that cooperates of the limiting section 57 of lid 4 slip usefulness, the receiving portion 45 by this limiting section 57 and lid 4, all be not limited to the structure that is located on the 1st terminal 5, also can be at least one side in limiting section and the locking mechanism is located at the such structure of the 2nd terminal.
In addition, also can a plurality of terminals all have the structure identical with the 1st terminal 5.
The 1st terminal 5 and the 2nd terminal 6 are not limited to be crimped on from the top the so-called upper contact type on the flat flexible cable 7, also can be for be crimped on contact type under the what is called on the flat flexible cable 7 from the below.
In the above-mentioned execution mode, though illustrated that with FPC a example as flat flexible cable 7, electric connector 1,101 of the present invention also can be useful in FFC (Flexible Flat Cable) for example and wait other the installing of flat flexible cable.
Though embodiments of the present invention are had been described in detail, but the concrete example that these only use for clear and definite technology contents of the present invention, the present invention should not be confined to these concrete examples and explain, thought of the present invention and scope only limit according to other attached claim scope.
