Description

BACKGROUND OF THE INVENTION SCEMs (Small Computer Consumable Modules) are a type of small computer construction in which various small modules often take the form of small circuit boards or tiles. Are stacked at several selected locations on the motherboard. In one construction, the connector is approximately 7.62
Must be located within a 3 x 3 inch circuit board area. The connector has 400 contacts arranged in six rows in a small area.
As a result, the centers of the contacts must be spaced about 1 mm along each row, requiring the use of very small contacts. Such a reliable, low-cost installation of a large number of small contacts would be of considerable value.

In one embodiment of the present invention, a method is provided for mounting multiple contacts of a connector into holes in a circuit board and a connector device configured to facilitate such mounting, thereby providing multiple connectors. Can be installed accurately and at low cost. The method includes first placing an upper end of a contact in the upper housing, the contact having a mounting portion with an upwardly facing shoulder located a distance below a lower surface of the upper housing. . An elongated push bar is inserted along the row of contacts between the upper portion of the mounting portion of the contacts and the lower surface of the upper housing. The upper surface of the upper housing is pushed downward by a large force, which force is transmitted through the push bar to the top of the mounting portion of the contact, which fits tightly into a hole in the circuit board. Thereafter, the push bar is withdrawn.

Prior to inserting the lower ends of the contacts into the holes in the circuit board, the alignment element lays the lower ends of each contact sideways to deflect the lower end of each contact and align it with the corresponding hole in the circuit board. Push. Preferably, each alignment element is in the form of a bar having a width greater than the thickness. Each alignment bar is initially set so that its width is vertical, then
As the alignment bar is rotated and the width becomes horizontal, the adjacent lower ends of the contacts are deflected away. The lower end of the contact projecting from the lower surface of the circuit board has a tapered deflector projecting from the upper surface of the lower housing to slightly deflect the tip of the contact laterally into a hole in the lower housing. Attached to the lower housing.

The present invention will be understood from the following description with reference to the accompanying drawings.

FIG. 1 shows various modules 12, 14, 16 connected together,
Also shown is a connector system 10 that also connects to modules in the form of a motherboard 18. This type of structure is designed so that the module expands the capabilities of a small computer. Each module 12 to 16 includes a module connector device 22 to 26 that connects the modules to one another and also to the connector 20 on the motherboard 18. Each central module connector 22 and 24 includes an upper housing 30 and a lower housing 32 on the back-to-back sides of the circuit board 34, and multiple contacts extending into the respective housings 30 and 32 through the circuit board. With the module connector 20 at the end
26 has a connector housing only on one side of the corresponding circuit board. Of course, terms such as "upper", "lower", "vertical" and the like are only used to assist in describing the invention, and the system can be used in any orientation with respect to gravity.

FIG. 2 shows an arrangement including only the motherboard 18 and the two modules 12 and 16. Figure 3 shows the top two modules
An arrangement comprising 14 and 16 and corresponding connector devices 24 and 26 is shown. The above arrangement or a more complicated configuration is used.

As shown in FIG. 3, the connector device 24 includes an upper connector housing 40 and a lower connector housing 42 located relative to an upper surface 44 and a lower surface 46 of the circuit board 34, respectively. The numerous contacts 50 are arranged in six rows of 51 to 56. Each contact is mainly in the upper housing
It has an upper end portion 60 located within 40, a lower end portion 62 located primarily within lower housing 42, and a mounting portion 64 which is snap fit or press fit into the circuit board and is located within hole 66 in the circuit board. The mounting portion 64 forms an upwardly facing shoulder 78 used to mount a contact in a hole in the circuit board. As shown in FIG. 8, the holes 66 in the circuit board, located in six columns 51-56, are staggered, with rows 70 of holes 51,5.
Include holes in 3 columns of 3,55, while row 72 of the next hole is another 3 columns
Include holes in each of 52,54,56. For this reason, only three rows of contacts are shown in the cross-sectional view of the connector arrangement, and the corresponding contacts of the other three rows are hidden. Therefore, two contacts 50
In the simplified cross-sectional view of FIG. 5 showing A and 50B, contact 50B is shown in its entirety, while another contact 50A is shown only in one part.

As shown in FIG. 6, the upper end 60 includes a base receiver 70 which is located in an interference fit with the wall of a hole 72 in the base 74 of the upper housing 40. The upper end 6 also includes a beam 76 that couples to the contacts of another connector device. Also, the upper end 60 is connected to the upper surface 44 of the circuit board and the lower surface 84 of the upper housing 40 located directly around the periphery of the contact.
And an uncovered exposed portion 80 located in an interval 82 between them. Spacing 82 has a distance Y that is greater than the average thickness A of each contact end. The contact is also located in the lower housing 42 and at the lower end with a lower tip 92
90, and a base receiving portion 94 which is located by interference fit with the wall of the hole 96 of the lower housing.

The mounting portion 64 of the contact is tightly fitted in the corresponding circuit board hole 66, and such an interference fit may cause the upward or downward facing resulting from the contacts of the other connector when mating or unmating. It is the primary means of holding the contact in place against forces and the like. In one connector designed by the applicant, the center-to-center spacing of the contacts along each row is designed to be one millimeter. Each contact was made from a metal sheet having a thickness of 0.15 millimeters (6/1000 inches) and a width B of 0.38 millimeters (14/1000 inches). In addition, the force required to insert the plated mounting portion 64 into the hole 66 in the circuit board was 2.7 to 5.4 kilograms (6 to 12 pounds). A total of 1 to 3 tons (2400 to 4800 pounds) of force was required to force all mounting portions of the 400 contacts into their corresponding circuit board holes. It is noted that a weak force, such as one pound or less, was required to insert the base receptacle 70 of each contact into the corresponding hole 72 in the connector housing.

A number of contacts installed in one row have all mounting portions 64 bent in a C-shape as shown in FIG. 7, and upper and lower ends also bent as shown in the figure. It is simultaneously formed from a metal sheet in a state. Different locations of the contact ends, such as 60 for the C-shaped mounting portion 64, are available. 5 to 7 show the newest preferred positions according to the invention. As shown in FIG. 7, the upper end 60 of the contact extends from one side 67 of the upwardly facing shoulder 78 and there is nothing in the space above the other side 68 of the shoulder. The portion indicated by the width X on the shoulder can be bent to about two thirds of the cross section of the mounting portion 64.

The connector part, not shown, connecting the row of contacts to the carrier strip of metal sheet, the row of contacts still remains part of one metal sheet, and the upper housing 40 of FIG. Are inserted into a row of holes 72, at which time a moderate force is required and each contact is individually accessible at least from its bottom. After the rows of contacts are mounted on the upper housing 40, the contacts are cut from the carrier strip. The contacts are now fitted tightly into the holes in the circuit board.

9A shows that the upper end 60 of the contact is mounted on the upper housing 40, the lower end 62 of the contact extends downward, and the lower tip 100 of the lower end 62 of the contact is the upper surface 4 of the circuit board 34.
4 shows the connector device in a state of being located at or slightly above it. In this case, no large downward force is required, but three push bars in the form of 102, 104, 106 are inserted through the space between the contact shoulder 78 and the lower surface 84 of the upper housing 40. Rows 51,5
The orientation of the contacts is preferably such that the shoulders 78 facing upwards of the contacts in two adjacent rows, such as 2, can receive the same push bar 106. This reduces the number of individual push bars and also allows the push bars to be located on the shoulders of both rows of contacts. However, a separate push bar can be used for each row of contacts.

To ensure that all contact tips 100 are inserted into corresponding holes 66 in the circuit board, each tip 10
Preferably, 0 is located substantially on the axis 110 of the corresponding hole. In the initial state, the tip 100 is slightly laterally offset from the axis 110 and an elongated alignment element or alignment slightly above the tip 100 between adjacent rows of contacts, such as 51,52. A bar 120 is located. Each alignment bar has a width W (see FIG. 9A) greater than its thickness T (see FIG. 9B). Each alignment bar rotates about an axis 114 that is parallel to a row of contacts extending longitudinally of the alignment bar.
The alignment bar is initially set in the orientation shown in FIG. 9A so that the width W is vertical. As shown in FIG. 9B, the alignment bars are rotated 90 °, the width W is horizontal, and the position on the lower end 62 of the contact located closer to the tip 100 than the mounting portion by each alignment bar. As the 116 is deflected, the tip is positioned to align with the axis 110 of the cylindrical hole in the circuit board.

As shown in FIG. 9C, the next step is to lower the upper housing 40 slightly so that the lower tips 100 of the contacts are actually located in the holes 66 in the circuit board. The alignment bar 120 is then moved horizontally parallel to the row direction and the alignment bar is withdrawn from between the contacts. FIG.9D shows the device with the alignment bar pulled out, but with the lower tip 100 of the contact located in the hole 66 in the circuit board and the lower tip 100 of the contact in the hole 66 in the circuit board. Stays inside. FIG. 9E shows the next stage, where the mounting portion 64 of the contact is substantially positioned relative to the upper surface 44 of the circuit board and is inserted, for example, by a half, until it is inserted into the hole 66 in the circuit board. Push down the upper housing 40 by about an inch.

FIG. 9F illustrates the next stage, in which a large downward force F is applied to depress the upper housing 40.
Is applied to the upper surface 124 of the upper housing 40. The upper housing 40 pushes down the push bars 102-106, which pushes the mounting portion 64 down into the contact holes 66.

As described above, the large downward force F is applied to each mounting part.
64 is added to press fit into hole 66 in the circuit board. The upper housing 40 is preferably cast of a thermoplastic to have a reasonable degree of thermoplasticity, but its strength is lower than that of ordinary metals such as brass and steel. When a total of 2.7 to 5.4 kilograms (6 to 12 pounds) of downward force per contact is applied directly by the lower surface 46 of the upper housing 40 made of thermoplastic material,
High pressure is applied to the lower surface 46 of the upper housing 40 made of thermoplastic material, which breaks down and eventually prevents some contacts from being reliably inserted into the holes in the circuit board. Also, as shown in FIG. 5, the hole 72 in the base of the upper housing 40 is desirably much larger than the contact to pass the bent tip 130 of the contact through the hole, so that the mounting portion The area of the housing that is pushed down against the shoulder 78 becomes smaller. There is also the danger that the C-shaped mounting part will be deformed in the hole 72 of the housing. Ten
By using a push bar such as 6, a material such as steel, which is harder than the thermoplastic material of the housing, can be used. Also, the push bar 106 is located over most of the shoulder 78, but is open on the side from which the upper end 60 of the contact extends to provide more space for the contact. The downward force applied to the push bar 106 is applied through the upper housing 40 by a large force F (see FIG. 9F) applied to a large area of the upper surface 124 of the housing. The upper housing 40 has a spacer foot 132 at the bottom of the housing
Pressed down until it is substantially positioned against 4. Spacer feet 132 stably position upper housing 40 on the circuit board. The upper housing 40 is held alone to the circuit board by contacts, but independent fixtures can be used.
The next step after the contacts have been completely installed on the circuit board is to attach the lower housing 42 to the contacts against the lower surface 46 of the circuit board.

After the contacts and the upper housing 40 are completely mounted on the circuit board 34, the next step is to mount the lower housing 42 on the lower ends 62 of the contacts and the circuit board 34. The lower housing 42 has a base 140 with a hole 142 for receiving the lower end 62 of the contact. However, the lower tip 100 of the contact is offset from the hole 142 in the base.
The lower housing 42 is connected to the upper surface 146 of the lower housing 42.
Of the tapered deflector 14 extending upwardly from a large portion of the lower housing (the portion located between the spacer feet 148 of the lower housing)
4 are formed. As the lower housing 42 is moved upward, the tips of the contacts are tapered deflectors 144
And deflects slightly to one side into the holes 142 in the substrate. FIG. 9G shows a state where all the elements of the connector device 24 are installed on the circuit board 34. The push bar 106 can be removed by sliding horizontally from the space between the upper housing 40 and the upper surface 146 of the circuit board and parallel to the direction of the row of contacts. FIG. 9H shows a state in which all the installation devices of the connector device 24 have been removed.

FIG. 15 is a simplified diagram of the device 150 used to insert and remove the push bars 102-104, and insert, rotate, and remove the alignment bar 120. The device 150 includes a guide device 152 having three rectangular guide surfaces 154 that guide the push bars 102-106 to move between the bottom of the upper housing and the shoulder of the contact mounting portion. Each bar has a tapered front end 156 to facilitate insertion. The guide member also has three respective cylindrical guide surfaces 160 for receiving each of the alignment bars 120. The rear end of each alignment bar is a cylindrical rod 1 that slides and rotates within a cylindrical guide surface 160.
Fixed to 62. The guide device 152 is a guide device.
Can be slid up and down a short distance on a substrate 164 that guides the vertical movement of Substrate 164 has a pin 1 received in a corresponding hole 170 in the circuit board for accurate alignment with the circuit board.
It has a positioning device 166 with 68.

The upper housing 40 (see FIG. 9A) to which the end portions of the contacts are mounted can be installed by sliding horizontally over the push bar 102 and the alignment bar 120. Alignment bar
120 is rotated to the position shown in FIG. 9B. The guide device 152 is moved down a short distance, on the order of a thousandth of an inch, to the position shown in FIG. 9C, so that the lower tips of the contacts enter the holes in the circuit board. Alignment bar 120 (Fig. 15
) Can be rotated or removed at that position, and is withdrawn from the guide device 152 rearward, ie, in the direction of arrow R. Thereafter, the guide device is moved down a distance of the order of a half inch until the contacts and upper housing 40 are in the position shown in FIG. 9E. If the guide device 152 is not used to apply a large downward pressure to the upper housing 40, the push bars 102-106
Like the other bar 170, the push bar is pushed further forward, that is, in the direction of arrow F, until the rear end 172 of the push bar is pushed forward of the guide surface 154.

FIG. 16 shows the next stage, in which the upper housing 40 with the contacts 50 mounted and the push bar, such as 106, inserted therein has the piston 180 of the press 184 applied to a force of several tons. And an anvil 182. The circuit board is located on a column 186 that supports its position on the circuit board, just opposite the six rows of contacts. The rigid rubber plate 190 is provided on the upper surface 124 of the connector housing 40 to ensure that the downward force applied to the upper surface 124 is evenly distributed on that surface.
Installed in Hard rubber plate 190 is a thermoplastic housing 4
0 is softer than hard material. The press is then operated to lower the piston 180 to press the mounting portion of the contact into the hole in the circuit board.

Accordingly, the present invention provides a method and apparatus for facilitating the mounting of a large number of small-fit contacts on a circuit board. The method includes forming each contact having a generally upwardly facing shoulder and an upper housing having a lower surface facing downwardly spaced above the shoulder. The push bar is located between the contact shoulder and the lower surface of the upper housing, whereby the downward force applied to the top surface of the upper housing is transmitted through the push bar to the shoulder of the mounting part and contacts the hole in the circuit board. Gives a large downward force for press-fitting the mounting part. The pushbars can be installed in a direction parallel to the row of contacts, with each pushbar preferably being located relative to the shoulders of the contacts located in two adjacent rows. The lower tip of the contact is pushed into precise alignment with the hole in the circuit board by an alignment element that compresses the portion of the contact closer to the lower tip than the mounting portion. Each alignment element is in the form of a bar having a width greater than its thickness, and is arranged such that its width is vertical. As the alignment element rotates and its width becomes horizontal, portions of the pair of contacts are deflected away. The lower housing is inserted with the lower end of the contacts protruding from the lower surface of the circuit board by moving the lower housing upwards with respect to the contacts of the circuit board and the upper housing thereon. The lower housing has an upper surface with a tapered deflector that deflects the tip of each contact laterally and into a hole in the lower housing.

While specific embodiments of the present invention have been shown and described, changes and modifications may be readily devised by those skilled in the art, and such changes and modifications may be practiced without departing from the scope of the claimed invention. Should be included in the scope.
