Connector in the past as having such ZIF structure discloses Figure 16 to connector for flexible substrate 100 (with reference to patent documentation 1) shown in Figure 180.

Patent documentation 1: the spy opens 2003-217718 communique (3-4 page or leaf, Fig. 3, Fig. 4)

This connector for flexible substrate 100 in the past has (the left side Figure 16 from the place ahead The side) substrate that is concaved with the elongated slot-like of inserting for the end of flexible base, board 200 holds recess 101 Insulating properties housing 102, install from the rear of insulation shell 102 and in the length of housing 102 A plurality of contacts 103 of arranging with interval on the degree direction (perpendicular to the direction of the paper of Figure 16), Rotate the securing rod 104 of installing freely relative to housing 102.

Contact 103 has in the mounting groove that is pressed into housing 102 and contact 103 is whole fixing Be bearing in fixed part 103a on the housing 102, as cantilever support on fixed part 103a In two strands one also enters into substrate with free state and holds contact site in the recess 101 What form on 103b, the pivot center as another strand in two strands and butt securing rod 104 is protruding The follower 103c of the 104a of wheel section, stretch out and be welded on from the rear of housing 102 and expose housing The 103d of foot on the conductive pattern (not shown) of the circuit substrate of 102 installed surface, they Integrally formed by a conductive metal plate stamping-out.

Securing rod 104 makes two side-prominent pair of rotary shafts (not shown) on pivot center Pass the rotation hole 105 that wears on the lateral wall 102A of length direction both sides of housing 102, and Around rotating shaft between latched position shown in Figure 16 and retreating position shown in Figure 17, rotate from As. Cam part 104a, with this pair of rotary shafts in coaxial formation, follower 103c butt Bearing surface, become along the insertion side of connector for flexible substrate 100 in latched position To flat, and retreating position become perpendicular to this direction of insertion to erect direction vertical Long shape.

Around the rotation axis of securing rod 104 and the 104b of bar portion of integrally formed operation usefulness, the locator protrusions that does not show from the outstanding figure of its lateral surface is fastened in the location indentations 106 that the lateral wall 102A of housing 102 is arranged with in latched position, and the locational rotation of position and lock.

The connector for flexible substrate in the past 100 of Gou Chenging like this, under the state before flexible base, board 200 inserts, the retreating position rotation that securing rod 104 is erected to the direction of insertion of relative flexibility substrate 200.When making securing rod 104 at retreating position, cam part 104a becomes elongate shape as shown in figure 17, boosts the follower 103c of this cam part of butt 104a, makes the contact site 103b of cantilever support recess substrate and holds recess 101.Therefore, the flexible base, board 200 contact site 103b ground that can not contact contact 103 inserts substrate and holds in the recess 101.

After inserting flexible base, board 200, rotating operation securing rod 104 widdershins in Figure 16, Figure 17, when making it be in the latched position parallel with the direction of insertion of flexible base, board 200, cam part 104a becomes flat pattern as shown in figure 16, the follower 103c and the contact site 103b of cantilever support are returned to the free state that is not subjected to the external force effect, and outstanding in substrate holds recess 101.Therefore, when flexible base, board 200 inserted substrates and holds recess 101 in, the electrode that exposes on its corresponding position of Elastic Contact was with the electrode of the corresponding flexible base, board 200 of predetermined contact pressure electrical connection and contact 103.When the 103d of foot with contact 103 is welded on the conductive pattern of the circuit substrate that connector for flexible substrate 100 is installed, carry out being electrically connected of flexible base, board 200 and circuit substrate by contact 103.

If adopt this connector for flexible substrate 100, the contact pressure ground that then can not bear from contact 103 inserts flexible base, board 200, so, even also can inserting substrate with light insertion force, holds in the recess 101 crooked flexible base, board 200, again, utilize the elasticity of contact 103 self and Elastic Contact flexible base, board 200, cam part 104a is inoperative on this connects, even, also can keep connection status so securing rod 104 breakages or securing rod 104 come off from housing 102.

But, connector for flexible substrate 100 in the past, to be installed on the housing 102 with the number of electrodes of the flexible base, board 200 that will be connected contact 103 at least with quantity, before flexible base, board 200 inserts, must the 104a of rotating cam portion and make the contact site 103b of this all contact 103 recess substrate to hold recess 101.Therefore, if be connected with the flexible base, board 200 that is furnished with a plurality of electrodes, the contact number of then keeping out of the way also increases, and the rotation of securing rod 104 needs big operating physical force, so the number of electrodes of attachable flexible base, board 200 is restricted.

And, arrange and the number of electrodes of flexible base, board 200 contact 103 along the length direction of housing 102 with quantity, so thereby the erection space that housing 102 maximizes on circuit substrate increases, become the obstacle of high-density installation.

Again, passing the rotation hole 105 that wears on the lateral wall 102A of housing 102 for the pair of rotary shafts that makes securing rod 104 can't come off, as shown in figure 18, on the inside base of lateral wall 102A, form slit 107, lateral wall 102A to foreign side's bending rotating shaft is passed rotation hole 105.

Therefore, have following problem, i.e. the installation of securing rod 104 on housing 102 is lateral wall 102A to foreign side's bending pair of rotary shafts is inserted a pair of rotation hole 105, because difficult like this assembling operation, the formation of slit 107 in addition worsens the intensity of housing 102.

Summary of the invention

The present invention makes in view of these problems in the past, and purpose is to provide with light work power rotating operation securing rod and makes contact recess the connector for flexible substrate that substrate holds recess.

Again, purpose is to provide the connector for flexible substrate that does not make housing maximize and can be connected with the flexible base, board that disposes a plurality of electrodes.

Again, the connector for flexible substrate that provides securing rod to install to housing easily is provided purpose.

In order to achieve the above object, the connector for flexible substrate of scheme 1 is characterised in that, has: housing is concaved with the substrate that inserts flexible base, board and holds recess; Securing rod, be formed with rotating shaft, cam part and around the bar of the operation usefulness of rotating shaft, described rotating shaft is around holding the parallel rotating shaft pivot suspension of the length direction of recess on housing with substrate, and described cam part is configured on the rotation and cross section perpendicular to axial direction is non-circular; A plurality of face side contacts, have follower and front contact site, and be separated with the compartment of terrain holds recess along substrate length direction configuration, described follower cantilever support is on the fixed part that is fixed on the housing and utilize the cam part of the elasticity butt securing rod of self, described front contact site holds mode free to advance or retreat in the recess to hold one of recess with the displacement interlock of the follower of butt cam part from substrate towards substrate, with follower integratedly cantilever support on fixed part, and utilize follower to the displacement of restoring direction and outstanding in substrate holds recess; A plurality of rear side contacts, has back side contact site, and being separated with the compartment of terrain is installed on the housing along the length direction that substrate holds recess, the one side that described back side contact site and aforesaid base plate the hold recess above gap of thickness of flexible base, board at least that is separated by is to hold the opposed another side of one side of recess outstanding in substrate holds recess with aforesaid base plate;

Utilize securing rod from the rotation of latched position to retreating position, make the front contact site recess substrate in linkage with the follower of each face side contact of butt cam part and hold recess, and, utilize securing rod from the rotation of retreating position to latched position, the follower of each the face side contact by the butt cam part is to the displacement of restoring direction, make the front contact site outstanding in substrate holds recess, utilize the resilient clamp of face side contact and rear side contact to insert the flexible base, board that substrate holds recess, the front contact site is contacted with the electrode of each self-corresponding flexible base, board with back side contact site.

This connector for flexible substrate, when with securing rod during to the retreating position rotating operation, the front contact site of face side contact and the follower of butt cam part link and recess substrate and hold recess, and only the back side contact site of rear side contact is outstanding in substrate holds recess.Back side contact site and substrate hold the one side of recess, and the above interval of thickness of flexible base, board at least that is separated by holds recess so flexible base, board can not bear from face side contact and either party contact pressure ground insertion substrate of rear side contact.

After flexible base, board inserted substrate and hold recess, if securing rod is turned to latched position, the follower of each face side contact that then utilizes the butt cam part made the front contact site outstanding in substrate holds recess to the displacement of restoring direction.Flexible base, board is clipped between front contact site and the back side contact site, utilizes the elasticity of each face side contact and back side contact site, the front contact site is contacted with the electrode of each self-corresponding flexible base, board with back side contact site, and carry out mutual electrical connection.

The connector for flexible substrate of scheme 2, it is characterized in that: on housing, be concaved with groove, described groove holds the rotating shaft of securing rod and utilizes inner surface to guide the rotation around axle of rotating shaft from the opening that is communicated with foreign side, the follower of face side contact utilize self elasticity and to from the opening of groove the direction application of force, butt cam part towards the interior side of groove.

With the cam part of the rotating shaft coaxle of securing rod on the butt follower, follower is by to from the opening of the groove direction application of force towards the interior side of groove, so the rotating shaft that is received in the groove from the opening of housing can not come off from groove unintentionally, but rotate by the inner surface guiding of groove.

At this, the front contact site 4d of each face side contact 4 and the back side contact site 5d of rear side contact 5 are outstanding to opposed locations across flexible base, board 50, even so a

side contact

4,5 since vibration etc. retreat to the direction of leaving flexible base, board 50, utilize the elasticity of opposed the opposing party's

contact

5,4, flexible base, board 50 also can be followed rapidly and the so-called hit phenomenon that moment remove to connect can not taken place.

Securing rod 3 is turned under the state of latched position, securing rod 3 flatly is contained in bar to be held in the recess 7, and locator protrusions 11 is fastened in the location indentations 9, and latched position is positioned, so can not rotate from latched position unintentionally, and keep above-mentioned connection status.

Again, when substrate holds recess 6 and extracts flexible base, board 50, utilize the operating physical force of removing locator protrusions 11 and the degree that engages of location indentations 9, to erecting direction operating operation bar 14, with securing rod 3 from the latched position rotating operation to retreating position.At retreating position, front contact site 4d holds recess 6 from substrate and retreats, become the interval wideer so the back side contact site 5d and the substrate of free state hold the interval of the inner top surface 6a of recess 6 than the thickness of flexible base, board 50, flexible base, board 50 can not bear from the contact pressure of face side contact 4 and rear side contact 5 extract.

The invention is not restricted to above-mentioned execution mode, various distortion can be arranged.For example, in the above-described embodiment, be to make face side contact 4 and rear side contact 5 to the stamping-out direction deflection of stamping-out metallic plate, but also make its in-plane, promptly perpendicular to the contact of the direction deflection of stamping-out direction to metallic plate.

Again, rear side contact 5 is cantilever support back side contact site 5d and make it movable.But also can make back side contact site 5d expose substrate hold recess 6 inner bottom surface 6b be fixed on the housing 2.

And the cross sectional shape perpendicular to axial direction of the cam part 15 of securing rod 3 is non-circular getting final product, and can be designed to ellipse, polygon and other shapes.Again, cam part 15 is formed on the rotation axis individually accordingly with face side contact 4, but the follower 4e of a plurality of face side contacts 4 of butt on the cam part that also can form continuously in the axial direction.

Again, rotating shaft 10 is outstanding both sides that are arranged on securing rod 3, but also can form rotating shaft 10 on the rotation axis of 15,15 of cam part, and the guiding groove guiding rotation that utilizes housing 2 sides to be arranged with.

Industrial applicibility
