Background technology

Generally speaking, the connector that is used in mobile phone, charge-coupled device (CCD) video camera or the analog is extremely thin (so-called lighter, compacter connector), and comprises the contact with extremely narrow pitch arrangement.These connectors both can be applicable to flexible printed circuit board or flexible flat cable simultaneously, also can be only applicable to flexible printed circuit board.These connectors have such structure, and promptly by circuit board or flat cable are inserted in the socket of connector shell, circuit board or flat cable are brought to and the contacted state of the contact portion of contact.

These connectors are divided into two types haply.A kind of connector mainly comprises housing and contact, and flexible printed circuit board can be brought to and the contacted state of the contact portion of contact in being inserted into housing the time.This connector is so-called " non-zero insertion force " (NZIF) type.Another kind of connector mainly comprises housing, contact and slide block, so that flexible printed circuit board is clamped by housing and slide block.This connector is divided into two types again, and promptly so-called " zero insertion force " be type and " touching " type (ZIF).Existing several different methods is used to utilize housing and slide block to keep flexible printed circuit board.Yet, in many cases, be after flexible printed circuit board is inserted in the housing, slide block is inserted in the housing, so that circuit board is pressed against on the contact.The connector of " zero insertion force " type is disclosed in the hereinafter described patent documentation 1, and the connector of " touching " type is disclosed in the hereinafter described patent documentation 2.

The connector of " non-zero insertion force " type has such structure, and promptly flexible printed circuit board inserts in the housing by socket, contacts with the contact portion of contact to force circuit board, and needn't use slide block, so just can realize the connection of circuit board.Flexible printed circuit board is under pressure in inserting housing the time.When flexible printed circuit board contacted with contact portion, contact portion usually can be by specially crooked or bending, so that realize contact, perhaps the contact portion of contact often is symmetricly set on the circuit board both sides, so that contact portion is clamped circuit board.

Be formed with the slot of requirement on the housing, be used for contact is inserted wherein, and socket, be used for flexible printed circuit board is inserted wherein.Each contact mainly comprises the contact portion that is used to contact flexible printed circuit board or analog, be used to be connected coupling part on the substrate, be used for fixing the standing part on housing.These contacts are fixed in the housing by being press-fitted.The contact 64 of a kind of " zero insertion force " type connector has been shown among Figure 30 A and the 30B.Contact 64 is U-shapeds roughly, and mainly comprises: contact portion 22, and it is applicable to contact flexible printed circuit board 40 or flexible flat cable; Coupling part 24, it is applicable to and is connected on a substrate or the substrate; And standing part 42, it is used for being fixed on housing 12 by being press-fitted.

Patent documentation 4

Japanese Patent Application Publication document No.H5-326 discloses a kind of circuit board connector in 084.Described in the specification of this Japan Patent, connector can be realized reliable connection, thereby boost productivity, and do not need circuit board is subjected to displacement, even circuit board has the specific small-sized terminal that is used for the signal input and output or with the terminal of little pitch arrangement.Circuit board comprises a plurality of signal input output end along an one edge placement.Connector comprises the female terminal contact, they be arranged in the corresponding position of the signal input output end of circuit board on.After the opening of circuit board by terminal contact one side inserted in the connector, circuit board was urged and shifts to the contact of female terminal, so that signal input output end is brought to and the contacted state of the respective contacts of connector.Connector also comprises positioner, and it is arranged in the zone that is used to insert the insulator circuit board.After circuit board was inserted into the precalculated position, positioner was placed in this with circuit board.

Recent years, along with the miniaturization of Electrical and Electronic equipment, this connector of strong request is by further miniaturization.In addition, increasing demand is arranged recently, wish that connector has the line of negligible amounts, for example 4 to 10, this depends on user's requirement.On the other hand, hope can be inserted circuit board in the connector with slight power, can circuit board be remained in the connector with enough big power again simultaneously.In this case, insertion force and confining force can't be taken into account, thereby can produce following problem.

First point, in the prior art connector shown in Figure 30 A and the 30B, six layers of structure are arranged, i.e. the pushing part 68 of the contact portion 22 of the last lower wall of housing 62, each contact 64 and pressure receiving unit 70, slide block 66, flexible printed circuit board 40 or flexible flat cable on short transverse.In order to reduce the height of connector as far as possible, can dispense the pressure receiving unit 70 of each contact, to obtain along the five-layer structure on the short transverse.Yet intensity and specification requirement or customer requirements in order to guarantee each element just can not further reduce the connector height.

For the connector 60 shown in Figure 30 A and the 30B, the contact portion 22 of the insertion of circuit board 40 or flat cable and contact 64 presses against socket one side that action on circuit board or the flat cable only occurs in housing, therefore along with the miniaturization of connector, it is difficult more that this operation becomes.In addition, under the extremely narrow situation of the spacing that needs contact, contact only inserts the miniaturization requirement that can hinder or hinder connector the housing from a direction.

Second point, for above-described structure, being placed in this mode of housing socket one side with their coupling part at contact is arranged under the situation in the housing, the coupling part of contact is stretched out from housing, so that steering circuit plate or flat cable, like this, can be because of stretching out the miniaturization that has limited connector from housing in the coupling part.Under the extremely narrow situation of the spacing that needs contact, only contact is inserted the miniaturization that also can limit connector the housing from a side.

Thirdly, for such connector, promptly the contact portion of its contact is located on the symmetric position so that clamp flexible printed circuit board in both sides, and contact is often by interlaced arrangement, to realize the miniaturization of connector.In this case, be used to insert circuitous pattern on the circuit board of connector should be corresponding with the contact placement of connector be crisscross arranged.The ifs circuit plate is turned upside down mistakenly to be inserted in the connector, and then the circuitous pattern on the circuit board can be touched the contact portion of contact mistakenly, thereby causes being electrically connected defective or fault.If this electrical connection defective or fault, then connector itself or circuit board itself must be changed, thereby causes running cost to increase.

The 4th point in so-called " non-zero insertion force " type connector, is used for that circuit board inserted the power of connector and is used for the power that circuit board remains on connector is generally depended primarily on the contact force (or pressure) of contact.In other words, the confining force contact force that is substantially equal to each contact multiply by the quantity of contact.If it is 5N that the user needs confining force, then for the line number less than for 10 the connector, can not obtain the confining force of 5N.Therefore, circuit board may skid off from connector, to cause connecting fault.

Even in so-called " zero insertion force " type connector, after flexible printed circuit board is inserted in the connector, circuit board is pressed against on the contact by slide block, but the difference of this connector and " non-zero insertion force " type connector only is to insert by contact and causes initial pressure to increase in the connector, and the effect of the contact force of contact (pressure) is still occupied an leading position, therefore, in this connector, still there is such fact, promptly for the line number less than for 10 the connector, can not obtain the confining force of 5N, so circuit board may skid off from connector.

In the disclosed connector, the anchoring projection that is located on the slide block inserts the also anchorage part of interlock flexible cable in aforementioned patent document 3.Yet, in this connector, because the direction of insertion of slide block is identical with the direction of insertion of flexible cable, therefore the effect of the contact force (pressure) of contact is still occupied an leading position, so still have such fact, promptly for the line number less than for 10 the connector, can not obtain the confining force of 5N.

In patent documentation 2 and 3, in the combining structure of disclosed connector, can on the what is called in the document 2 " touching " type connector, add the anchorage part that is provided with on anchoring projection that is formed on the slide block and the used circuit board of connector that is formed in the document 3.For this combining structure connector, because the direction of insertion of circuit board is different with the rotation direction of slide block, therefore in some cases, even the line number less than 10, also can obtain required confining force to a certain extent.Therefore yet the elasticity of slide block is relatively poor, can be impaired by slide block when pulling out greater than the power of confining force or circuit board at circuit board.In addition, circuit board can be subjected to irregular power accidentally, for example normally along oblique upper to pulling force, rather than along with the rightabout power of direction of insertion.Because the direction of accidental irregular power may be identical with the rotation direction of slide block, therefore can not obtain required confining force sometimes.

The 5th point in order to increase signal density, more and more need be provided with contact portion on the both side surface of circuit board.Yet previously described prior art connector can not be applicable to and thisly have the circuit board of contact portion in both side surface, and can not be applicable to the more contact of thin space.More particularly, for disclosed in the patent documentation 1 " zero insertion force " type connector, after circuit board inserted in the connector, circuit board was touched the contact of connector along a direction pushing by slide block.Because press direction is a direction, therefore this connector can not be used for having the circuit board of contact portion certainly on both side surface.

In disclosed in aforementioned patent document 2 " touching " type connector, slide block rotates in the side that circuit board inserts connector.In this structure, circuit board is only pushed by slide block along a direction, and therefore this connector can not be applicable to the circuit board that has contact portion on both side surface.

The 6th point, along with the height of connector is significantly reduced, it is little of 0.15 to 0.25mm connector to obtain thickness at present from the market.For the housing as thin as a wafer in this connector, when inserting circuit board in the connector, housing may hold can't stand contact force, thereby makes housing distortion and cause and connect unstablely, causing connecting trouble or failure, even causes housing to damage.Make housing to such an extent that thicklyer can avoid this problem, but can not realize reducing of height.Disclosed connector has the contact that is arranged in the narrow-pitch in the patent documentation 1 and 2, and shape thinner (so-called lighter, compacter connector), and therefore above-described problem is even more serious in this connector.
