Abstract
A ZIF connector includes a base with an array of cavities for accepting pins on an electronic device. As in conventional ZIF connectors, each cavity has a contact in it and accepts a corresponding pin on an electronic device inserted through a cover that slides along the base to move the pins along a path in the cavities. The disclosed contact has a mating portion integral with a body portion that holds the contact in the cavity. The mating portion is positioned in the cavity for deformation by the pin as it moves form an insertion position to a connecting position. The mating portion is twisted so that its root end connected to the body portion and an opposing tip end form different angles with the path of the pin.
Description
The present invention relates to (ZIF) connector of a kind of zero insertion force, and in detail, relate to a kind of low inductance ZIF connector contact (contact), it has reduced the wearing and tearing of the pin that is mated connection, and makes the contact separation in the ZIF connector tightr.
The ZIF connector can make flimsy electronic device (as the microprocessor chip), is detachably connected on the wiring board.Such electronic device generally makes component package become to have the overall package of an array pin, and pin has hundreds of, extends from encapsulation with the latticed of rule.Pin not only is electrically connected electronic device with proper circuit on the wiring board, and electronic device is mechanically secured on the wiring board.
Preferably, these so-called pin grid array (PGA) devices can be installed on the wiring board in a kind of mode that allows it to be removed and install once more.And this device is accurate, and the diameter of pin is in 0.25mm arrives the scope of 0.5mm.They must be easy to install under the situation without undergoing transitional pressure.For this purpose, the ZIF connector is further improved.
The such ZIF connector that the present invention relates to has a lid that slides on a matrix, and electronic contact is arranged in the cavity.Cover the hole that aligns with cavity.Matrix is connected with circuit board by circuit board contact pin circuit element being soldered on the circuit element, and this contact pin is hung from above on contact point and from the matrix bottom and extended.Be under its situation of " opening " position at lid, the pin on the PGA device can freely pass the described hole that covers and be inserted in the cavity of matrix.When lid is moved to it when " closing " position, Kong Yuzhen cooperate and lightly the application of force with the engage contacts in these pins and the cavity.
A characteristic feature of this type ZIF connector is, because pin is propped up the contact by the application of force, thereby they make the contact point distortion.In case lid is closed, each contact is electrically connected with pin because of the resistance to deformation applied force makes it, provides enough frictional force so that these pins are fixed in the cavity simultaneously, and prevents that described PGA device from extracting out from connector.Similarly, lid is got back to its open position, discharge pin and allow to pull down this device.
The contact of prior art has adopted various forms to provide clamping action to pin.The known shape such as the patent No. are 4,498,725,4,988,310,5,489,217,5,489,218,5,597,320,5,609,495,5,692,920,5,733,150 and 5,791,929, United States Patent (USP) shown in.When these contacts more or less were fit to their purpose, it all met with the shortcoming that reduces ZIF connector whole structure.
With regard to essence, the ZIF connector relies on the strain of contact to clamp the pin of PGA device.As a result, the contact must provide resistance to deformation power.A kind of " flag (flag) " type contact has a finger piece that extends from a upright arm with joint pin.The exemplary of this types of contacts such as the patent No. are 4,498,725,4,988,310,5,489,217 and 5,609, and shown in 495 the United States Patent (USP).
The cross-sectional area of described upright arm must be enough little of to allow strain, and this strain makes the contact produce friction grip power and clamps described pin and reach good being electrically connected with it.Yet arm also provides a current channel to contact pin, and this contact pin is connected to wiring board with the contact, and little cross section has poorly increased the inductance and the resistance of this connection.In addition, described finger piece or " flag " slip into the position and at roughly the same position contact pin, like this, cause the extra wearing and tearing of pin with pin along the contact.Pin is electroplated a kind of valuable metal usually, as gold, to improve the conductibility that connects.The thickness of gold plate is generally indicated by the manufacturer of PGA device.Therefore, it is impossible that the thickness that increases coating compensates wearing and tearing extra on the pin, even the cost that adds thickness coating and increase can be accepted.
The patent No. is 5,489,218 and 5,733, and 150 United States Patent (USP) provides the change of the described flag form structure of mentioning in top other patent, but they do not solve problem intrinsic in the structure.
Other patent of listing is above represented the type of alternative contact.For example, United States Patent (USP) 5,597,320,5,692,920 and 5,791,929, have the contact area of a dimple at the top of a upright arm.Yet also there is deficiency in they, wherein they do not solve when described pin when contact surface slides, put the problem that contacts with it separately at one.

Fig. 4 is the drawing in side sectional elevation of obtaining along 4-4 line among Fig. 3.
Fig. 5 is the matrix vertical view of a ZIF connector of the present invention.
Fig. 1 represents a traditional ZIF connector 10, has a matrix 12 and one and is installed in the lid 14 that is used on the matrix 12 with its slide relative.Cover have with PGA device (not shown) on the be complementary through hole 15 of form of the form of pin array.Have many identical cavitys 16 on the matrix 12, wherein dispose the contact.Cavity 16 holes 15 common and that lid is interior coincide.Except the profile of the cavity 16 described in detail below and contact, described connector 10 is general.
ZIF connector 10 has a L shaped actuator lever 18, and it comprises a cam arm 22, and this cam arm is arranged on one by the groove 24 of the trailing edge that closes on matrix 12 with close in the groove 26 determined passages that cover 14 trailing edge.Actuator lever 18 also comprises holistic control arm 28, extends along a side of connector 10.Control arm 28 is with the direction rotation of arrow A indication, so that the lid 14 that is contained on the matrix 12 slides in the direction of arrow B.Especially, groove 24 and 26 is constructed such that control arm by arrow A 2 directions motions, enters the position that there is an angle of inclination on a plane with connector, above matrix 12 along arrow B 2 direction slide lids 14.When lid was positioned its open position immediately, the pin on the PGA device can freely pass hole 15 and be inserted in the cavity 16.Be directed downwards along arrow A 1 and promote control arm 28, make and cover 14 and move along arrow B 1 direction.It makes it go into the position to the pin application of force and props up contact in the cavity.Control arm 28 rests on and is positioned at (not shown) on the stop that covers on 14 sides, and it is in its off-position immediately, makes PGA device fix in position simultaneously.
Fig. 2 represents a contact 100 of one embodiment of the present invention.This contact has one and roughly is the plane body part 102 at its marginal belt maintenance barb (retention barb) 104.This maintenance barb provides an interference fit with cavity 16 end walls, in cavity the contact is fixed on the appropriate location, as following described in detail with reference to Fig. 3 and Fig. 4.Can understand and to take any suitable mode to be used at cavity internal fixation body part.It is any that the contact is firmly located and made its fixed structure and barb 104 is equivalent.
The contact also comprises a mating part 106, and it has a butt 108 and a top 110 at the body part top.One whole contact pin 111 is hung from above on body part.Because the contact can be made by extremely thin material, contact pin comprises a ribs 112 that swells with optimum, and it is an another advantage of the present invention, and promptly ribs provides additional rigidity to help the ZIF connector is connected on the wiring board.In a conventional manner, each cavity 16 internal fixation has a contact 100, passes bottom opening 218 by the compressing contact, puts in place up to the end wall 230 of barb 104 and cavity and 234 secure engagement (seeing Fig. 3 and 4).Contact 100 is fixed on the definite mode in the cavity 16, will obtain understanding from the detailed description below in conjunction with Fig. 2 and 3 pairs of cavitys of the present invention.Enter in a contact in the chamber behind certain position, contact pin is extended from matrix by a bottom opening.When covering in position, whole connector for good and all is fixed on the wiring board by contact pin being soldered on the circuit diagram of wiring board.
By the sheet metal blank of punching press appropriate materials (as phosphor bronze), each contact 100 is made into a slice to form band S as shown in phantom in Figure 2.This has a body portion BP, and vertical finger piece F extends from it.Use proper implements punching press forward (FWD) S can be under the intercepting of snick line 1 place single contact.On the other hand, the contact can be moved down from finger piece by snick line place cutting shown in the figure.In both cases, the body part 102 of each contact, mating part 106 and contact pin 111 one each other.
Yet, under each contact is intercepted before, band bears the contact that suitable processing is finished.By using proper implements pressure-sizing contact pin 111 to form the ribs 112 of protuberance.In addition, an end of mating part 106 forms the circular arc (seeing Fig. 3 equally) that radius is r through pressure-sizing, and this circular arc helps guid needle P to enter into the sidewall 222 in chamber and the space between the contact 100, as shown in Figure 3.
Be another unique appearance of contact that forms an importance of the present invention, mating part 106 is reversed out the plane of body part 102 around an axle that extends between butt 108 and top 110.In described embodiment, torque shaft is perpendicular to the passage (see figure 3) of pin.Though can use the described mating part that reverses of different technology moulding, it is preferred having found to use proper implements pressure-sizing band.In a preferred embodiment, the top 110 of mating part forms one and is the straight line (see figure 3) of angle α with butt 108.The value of α will come to determine for different contacts by experiment.For a phosphor bronze contact, the height h of its mating part is 3.79mm, and width w is 1.77mm, angle α should be 16 ° 42 '.The numerical value of angle α depends on the mechanical performance of slider material, mainly is modulus of elasticity, and the overall dimension of mating part 106.Selecting the requirement of the suitable numerical value of angle α, is conspicuous in the description of how the present invention being operated with the ZIF connector performance of improving prior art.
The course of processing that band also bears other, these courses of processing are used to process the contact of a ZIF connector traditionally.The part that will contact with pin P on the contact surface that provides by mating part 106 earlier by electronickelling then by electrogilding, nickel provides adhesive force and the resistance to wear of a basic unit in order to improve gold plate, gold plate is in order to reduce the resistance on contact-pin contact-making surface.The electrotinning kupper solder is as discussed above in the contact pin 111, in order to contact pin is soldered on the wiring board.Finish after the desired course of processing in contact through all, as discussed above, single contact is gone up from band S and is intercepted.
The shape of cavity 16 preferably combines Fig. 3 and 4.Fig. 3 is the vertical view of the amplification of one of cavity 16.Fig. 3 has shown the appropriate location of contact 100 in cavity of one embodiment of the present invention.Fig. 4 has omitted the contact to clearly show the inside in chamber.The path limit of the center line of pin P in the chamber axis L of cavity.Pin P and axis L are represented by dotted lines in Fig. 3.
For simplicity, the top of Fig. 3 is referenced the direction into forward, finishes the direction that moves when a PGA device is installed because it is pin P in the ZIF connector.The term of service orientation all the time or position is described, " vertical, " " bottom, " " top, " and similar term as " forward, ".Like this usage embodiments of the invention for convenience of description only.The reference of these terms orientation when describing the accompanying drawing structure in no case should be used as restriction of the present invention.
Cavity comprises the opening 200 that passes matrix 12 extensions.This opening has a backing sidewall 202, and it comprises a compartment 204 and a vertical component 206.Fig. 2 and 3 is combined, can see this compartment better.One upright part 208 is set at after the vertical component 206.One sloping portion 210 extends between 212 to cross spiders 214 of bottom margin of vertical component 206, and this cross spider has the lateral edges 216 of the upstanding portion 208 that is provided with backward.That is, sloping portion 210 makes cavity narrow down from the top to the bottom opening 218 that has vertical wall 219 gradually.
One cam-shaped sidewall 220 is relative with backing sidewall 202.This cam-shaped sidewall has three vertical components.The firstth, insertion portion 222 provides a big relatively space, and when covering in its rear positions in order to insert the PGA device, pin P assembles within it.The secondth, the part 224 of taper, this part tapers to third part smoothly, lock part 226.Described cam-shaped sidewall ends at horizontal bead 228 places.
Be appreciated that the end wall with described opening 200 is not exclusively accurately with the term " vertical " that sidewall uses.That is, described sidewall and end wall generally all have the inside gradient or the tapering of slight amount from the top to the bottom, be reflected among the Fig. 3 that describes sidewall and end wall with two-wire.Matrix is generally made by a kind of suitable plastic material mold pressing as an independent part, and requires a slight gradient is arranged so that the matrix of finished product is taken out from mould.
According to the present invention a PGA device is assembled on the ZIF connector, by with arrow A
2Direction is rotated control arm 28 and will be covered 14 and be placed on it and " open " position; That is, make lid with arrow B
2Direction moves.Cover on 14 when the PGA device is placed on, and pin is when passing hole 15, each pin P enters into one of cavity 16 on the matrix 12, in the insertion portion 222 and the space between the contact 100 of described cam-shaped sidewall.The represented position of dotted line among Here it is Fig. 3.Then, move with arrow A 1 direction with control arm, lid 14 is subjected to arrow B
1The power of direction, thereby, pin P is applied the pressure of equidirectional.As understandable among Fig. 3, pin P begins to contact with the part 224 of the taper of cam-shaped sidewall 220, forces pin P to be resisted against on the contact surface of mating part 106 of contact 100.
Along with lid 14 continues with arrow B
1Direction moves, and pin P makes contact 100 with the bending of arrow C direction, is resisted against on the vertical component 206 of backing sidewall 202, as shown in Figure 3.Along with the bending of described mating part, the rear end 120 of described mating part enters the compartment 204 of backing sidewall 202.When lid 14 arrives it fully during " closing " position, pin P contacts with the lock part 226 of cam-shaped sidewall 220.Lock part 226 is parallel with the direct of travel of pin P.In this, contact 100 fully is out of shape, and the reaction force that is produced because of distortion provides desired the electrically contacting between the contact surface of pin P and contact 100 that obtains.
There are many advantages that surpass the prior art contact contact according to the present invention.Along with moving of lid, the profile of reversing of mating part makes the contact point of itself and described pin move along the length direction of pin.Cross-hauling W shown in Fig. 2 depicts pin contacts the institute edge with the mating part 106 of contact 100 line.The path D of line W and pin has an angle β with respect to the contact.In the ZIF of known prior art connector, the paths merge of line W and pin, i.e. β=0 °, thus on single point, wear and tear pin.On the contrary, the present invention will be worn and torn and will be distributed on the pin along a line, be better than on the single point in the prior art.
Another advantage of the profile that the quilt of contact reverses is that contact point is along the mobile harmful remains that help to reduce on the potential contact-making surface that is accumulated in contact-pin of pin.By at the axis of pin and the slanted angle between the line W, described remains trend towards being walked by " plough (plowed) ".
Other advantage is to come from a part to make contact 100 bendings, and this part and mating part are with wide, and elimination makes the narrowed portion of contact of the prior art distortion at this place.The contact can be made by thinner material, is owing to provide the power (and therefore this power provides and the electrically contacting of pin) of opposing contact distortion to be decided by the crooked local cross-sectional area in contact.That is, because the length of sweep is longer, so the thickness of material can reduce.Aforesaid according to the embodiment of the invention the contact can " thick sheet material be made by 0.004." flag " type contact of the prior art of comparing with the present invention " cuts so-called flag-shaped the thick sheet material and make, and the material under will cutting is abandoned from 0.008.Because contact of the present invention can be made by very thin sheet material, so its use material seldom, this has reduced the cost of contact again.In addition, the electrical characteristics of described contact improve, and are because it has removed the part that the width in the prior art contact reduces, and reduce part at this width and have increased inductance and resistance unfriendly.
Also having another advantage is that this profile provides seamlessly transitting from its off-position to open position to lid.When pin arrived bending, the depressions or protrusions place of the ZIF connector contact of prior art, the contact of being reversed had reduced the peak value of the active force that is applied.This also has reduction must put on power effect on the control arm 18, makes that control arm 18 can be by plastics rather than metal manufacturing.Such further cost that has reduced described ZIF connector.
Thin material and the contact of reversing profile allow cavity 16 to arrange more closely.Like that, the ZIF connector that allows to combine with the present invention holds more compact arranged faller gill.The PGA design is to want to allow each device that more pin is arranged, and PGA manufacturer constantly specifies the ZIF connector of higher pin density.
Each cavity can be done narrowlyer, is because the present invention has removed feature crooked, depressions or protrusions.That is, the contact that has resemblance like this needs the cavity of enough width, to hold the deflection of the contact of contact pin and the feature of protuberance in fact.
In addition, the torque characteristic of the contact of this respect according to the present invention allows described cavity to be positioned to tightr.Preferably see Fig. 5, each cavity is wide at rear end 16R, and 16F is narrow at front end.Such profile allows described cavity to be nested together more closely.Effect is, when each cavity combinations that has reduced width together the time, provides the chamber of bigger density.
Certainly, not deviating under the condition of the present invention, can make a lot of modifications in said structure, for example, described contact does not need to use the sheet metal manufacturing, does not need the actual sheet metal that reverses that reversing of described mating part is provided yet.Do not need cavity to adopt represented and accurate shape described above in the accompanying drawing yet.For reaching the present invention's shape advantages associated that can realize and cavity, cavity only needs a wide relatively front end, is used to the distortion of admitting pin and allowing the contact, and a narrower rear end, is used for reaching nested effect described above.
When the preferred embodiments of the present invention are described, be to be understood that under the premise without departing from the spirit and scope of the present invention, except that those specific examples above-mentioned, can also make various variations and modification to the present invention, it only is limited in the scope of appending claims.
