Summary of the invention

The present invention is just in order to solve above-mentioned technical task, the connector that purpose is to provide simple structure and can obtains stable contact pressure.

Connector of the present invention comprises: a plurality of through holes that form on insulating barrier, and joint, in the through hole under this joint is arranged in a plurality of through holes, it is characterized by, joint possesses: base portion, along the docking point portion that the above-below direction of base portion extends respectively, be connected in the convex shoulder of base portion left and right sides edge, and the fastener on the base portion under being disposed at, in the through hole of insulating barrier, possesses the guiding slot part of joint being taken in maintenance with the convex shoulder, and the stopper section of fastener to prevent that joint breaks away from of disturbing joint, and have along the rake of the direction of insertion of this joint, joint is contained the state that can move freely at the thickness above-below direction of insulating barrier that is held in, and joint is being symmetry corresponding to the above-below direction of the central authorities of this base portion and each direction of left and right directions.

This connector is pressed and remains in into connecting object that the overlapping state connects, be between electronic component and the electronic component, between the LSI or IC and printed base plate, printed base plate and printed base plate of for example LGA type.

This connector also comprises for example lga socket etc.

When being held in the connector pressing clip between electronic component, the electrode that faces one another of electronic component face with each other with conductor, be that the contact portion of joint is by compressive strain and conducting.

This joint is accommodated in a plurality of through holes (reception hole) that form after thickness direction connects insulating barrier.

The stopper section is arranged on the through hole inwall, and when joint moved in through hole along the guiding slot part, the stopper section was limited to the fastener of joint.

Thus, joint can remain in the through hole by stopper section and guiding slot part, and can move freely at the thickness above-below direction of insulating barrier.

In the case, when the bottom side at guide channel forms outstanding abutting part, and on the through hole inwall of insulating barrier and when forming the stopper section near the peristome side of guide channel, joint just can its end, convex shoulder contact with outstanding abutting part on being formed at guide channel or the fastener of joint and scope that the stopper section contacts in move freely.

So,, just can when pushing connection, make the joint knee-action, adjust the contact pressure that connector two regards to the electronic component electrode automatically and equably by joint being contained in insulating barrier and having predetermined tolerance.

Again, because the contact pressure of joint adjusted automatically, so but be arranged at the also equalization of contact pressure of a plurality of each connector on the connector.

When joint being inserted in the through hole that is assembled into insulating barrier, being formed at fastener on the joint crosses the stopper section in the through hole and inserts, if the direction of insertion along joint on the stopper section of the through hole that is positioned at insulating barrier forms rake, then, make the assembleability of joint good as long as insert along this rake.

Therefore, form rake along the direction of insertion of joint, the aperture area ecto-entad of the through hole of insulating barrier is narrowed down gradually and form inclination in this what is called.

When with joint when direction is made symmetric shape up and down, then the direction inserted in the perforation of insulating barrier can be arranged in a plurality of joints on the anchor clamps back and insert insulating barrier in the lump with insertion machine etc. just without limits.

The invention effect

Adopt connector of the present invention, joint does not need to utilize pressure to fix as connector in the past, but by taking in guiding slot part that keeps joint and the fastener of interfering joint with the convex shoulder to prevent that the stopper section that joint comes off from being kept.

And joint can move freely at the thickness direction of insulating barrier.

Therefore, when electronic component is connected to each other, can make for the mutual equalization of the contact pressure of electronic component electrode, stable by the mobile of joint.

Make each joint and the equalization too of the interelectrode contact pressure of electronic component of connector thus, can obtain good connection status.

Again, because contact portion strain sleekly under the state that does not disturb the through hole inwall, so in long stroke, can obtain stable spring pressure, the insulator of the corresponding various sizes of energy.

Again,, can reinstate insertion machine from the state that is accommodated in shell and be arranged, be assembled on the insulator in the lump then, so production efficiency is very good because joint is symmetric shape in direction up and down.

Embodiment

Fig. 5 is the embodiment of connector of the present invention.

Fig. 5 (1) is a vertical view, and Fig. 5 (2) is a upward view, and Fig. 5 (3) is an end view.

Connector 10 is that the face direction at insulating barrier 20 disposes a plurality of joints 30.

This connector 10 is for example installed the LSI of LGA type as lga socket and is connected with printed base plate on the one side shown in Fig. 5 (2).

Fig. 1 (1) is the vertical section schematic diagram with near the expansion joint 30 of connector 10, and Fig. 1 (2) shows A-A line sectional drawing, and Fig. 1 (3) shows the local figure in B visual angle.

Again, Fig. 2 is a perspective insulating barrier 20 and describe the partial perspective view of through hole 21 and joint 30.

Connector 10 is provided with the through hole 21 that connects insulating barrier 20 at the thickness direction of tabular insulating barrier 20, and possesses joint 30 in through hole 21.

Joint 30 is in Fig. 1 (3), in the wall 21b of the through hole 21 that roughly is the T font side configuration base portion 31 vertical with the face direction of insulating barrier.

A pair of convex shoulder 34 is extended out by the both sides of base portion 31.

Again, connect in the both sides of insulating barrier 20 thickness directions of base portion 31 32a of contact portion, 32b are set, and they are extended towards through hole 21 outsides.

Till the 32a of this contact portion, the wall 21a side that 32b extends to face one another with base portion 31.

Again, on base portion 31, towards the outstanding overshooting shape fastener 33 that is provided with of the wall 21b of base portion side.

The outstanding stopper section 22 that forms on the wall 21b of the close base portion 31 of through hole 21, moving of fastener 33 limited by interfering in this stopper section, prevents that joint from coming off.

The clearance t 0 that between this stopper section 22 and fastener 33, has preset distance.

Thus, joint 30 is limited in the t0 scope to the amount of movement of the peristome 21e of through hole 21 side.

Again, wall 21c, the 21d of Fig. 1 (3) face guiding slot part 23 in the key diagram that joint is installed in through hole shown in Figure 3.

Side at this guiding slot part 23 is provided with peristome 23b, and opposite side is provided with the outstanding abutting part 23a for the outstanding butt of end, convex shoulder 34a.

This guiding slot part 23 is the groove of thickness of insulating layer direction, as Fig. 1 (2), shown in Figure 2, embeds convex shoulder 34.

Between the wall of convex shoulder 34 and formation guiding slot part 23, be provided with the gap shown in width t1, t2, the t3 again.

Joint 30 is that a side end, the convex shoulder 34a and the fastener 33 of outstanding abutting part 23a butt or joint are subjected to stopper section 22 restrictions in the moving range of insulating barrier 20 thickness directions.

Joint 30 by and guiding slot part 23 walls between clearance t 1, t2, t3 are set and can slick and slyly move.

Followingly the installation of joint in through hole is described with reference to Fig. 3.

The installation of joint 30 in the through hole 21 is from peristome 21e side convex shoulder 34 to be embedded into guiding slot part 23 shown in Fig. 3 (1).

So, shown in the vertical section schematic diagram shown in Fig. 3 (2), further be pressed into though fastener 33 is conflicted mutually with stopper section 22.

In the case, because of the direction of insertion along joint on stopper section 22 forms rake 22a, so strain is made along this rake in fastener 33 or stopper section 22, fastener 33 is crossed stopper section 22.

The outstanding abutting part 23a butt of Fig. 1, end, convex shoulder 34a shown in Figure 2 and guiding slot part forms guiding slot part 23 with stopper section 22 and fastens only state of card then.

So, joint 30 just can move in the scope that the outstanding abutting part 23a restriction that is subjected to guiding slot part from the position that is subjected to fastener 33 and stopper section 22 restrictions to end, convex shoulder 34a is moved in the position of thickness of insulating layer direction.

The location in the face direction of insulating barrier 20 of joint 30 is undertaken by convex shoulder 34 being embedded into guiding slot part 23.

Joint 30 the above-below direction of Fig. 1 (1) of insulating barrier 20 just thickness direction, form symmetric shape up and down with the face direction of the left and right directions of Fig. 1 (2).

Therefore, when joint is assembled into insulating barrier, can shell etc. is back fitly to be arranged on the anchor clamps with insertion machine in that joint is loaded on respectively, again insulating barrier is put on the anchor clamps back and assemble in the lump, so the production efficiency height with kludge.

Below the connection that the electronic component of connector of the present invention is anticipated is each other used in explanation.

Fig. 4 (1) shows the vertical section schematic diagram that connects preceding state, and Fig. 4 (2) is the vertical section schematic diagram that shows when connecting.

Connector 10 is shown in Fig. 4 (1), is disposed between the LSI1 and printed base plate 2 of the connecting object that connects into stacked state, and shown in Fig. 4 (2), pressing clip is held between LSI1 and the printed base plate 2.

Thus, the 32a of contact portion, 32b that relative each other boss (electrode) 1a, 1b push connector 10 by both sides make its strain, via joint 30 conducting reciprocally.

At this moment, because joint 30 can move up and down being subjected to stopper section 22 and the outstanding abutting part 23a restriction of guiding slot part and being guided in the preset range of slot part 23 guidings, therefore the boss 1a of LSI1 and contact pressure, the boss 2a that reaches printed base plate 2 and the contact pressure between the 32b of contact portion between the 32a of contact portion can be adjusted to identically, and make it stabilisation.

Again, the 32a of contact portion, 32b being bent to form in the scope when strain can not interfered with the wall of through hole 21, can be with stable contact pressure contact electrode 1a, 2a.

Therefore as shown in Figure 5, a plurality of joints that are arranged on the connector 10 can be done good connection equably.
