ATTORNEY United States Patent 3,391,382 CONNECTOR Joseph Leibovitz, San Jose, Calif., assignor to General Micro-Electronics Inc., Santa Clara, Calif., a corporation of Delaware Filed Mar. 10, 1966, Ser. No. 533,164 Claims. (Cl. 339-174) ABSTRACT OF THE DISCLOSURE A connector for establishing electrical connection between a microelectronic device and a circuit board. An electrically insulative body is formed with spaced locking surfaces, and a cover formed With similarly spaced locking surfaces engages the locking surfaces of the body to secure the cover, and a device, to the body. The cover is flexible and resilient so as to flex into a bowed configuration intermediate the spaced locking surfaces when the cover is secured to the body. Leads are associated with the connector so that a device clamped between the flexed cover and the body has its lead wires pressed against the connector leads.
The present invention relates in general to electrical connectors, and more particularly to an electrical connector adaptable for use with microelectronic devices.
An object of the present invention is to provide a connector adaptable for use with a wide variety of flat pack microelectronic devices.
Another object of the present invention is to provide a connector that achieves a tight, positive connection for a microelectronic device.
Another object of the present invention is to provide a connector for a mircoelectronic device that is easy to install.
Another object of the present invention is to provide a connector for establishing an electrical connection between a flat pack microelectronic device and a printed circuit board.
Another object of the present invention is to provide a connector for a microelectronic device with a snap-on positive locking cover.
Another object of the present invention is to provide a connector for microelectronic devices in which the lid thereof is pressed down for locking and is maintained in tension for improved gripping action.
Another object of the present invention is to provide a connector for microelectronic devices with a yieldable lid for contact press fitting.
Other and further objects and advantages of the present invention will be apparent to one skilled in the art from the following description taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a perspective view of the connector of the present invention illustrated with a flat pack microelectronic device and a printed circuit board.
FIG. 2 is a perspective view of the base of the connector of the present invention.
FIG. 3 is a perspective view of the base shown in FIG. 2 with the connector conductor leads mounted thereon.
FIG. 4 is an end elevation view of the base with the connector conductor leads mounted thereon.
FIG. 5 is a perspective view of the cover of the connector of the present invention.
FIG. 6 is an end elevation view of a flat pack semiconductor device mounted within the connector of the present invention.
Illustrated in FIG. 1 is a conventional printed circuit board 10 with a plurality of spaced conductor strips 3,391,382 Patented July 2, 1968 "ice 11-32 fixedly secured thereon. A conventional flat pack microelectronic device 35 is spaced above the printed circuit board 10 and includes a plurality of device conductor leads 41-62, which are generally made of Kovar. The flat pack microelectronic device 35 is mounted within a connector 65 of the present invention, which includes a plurality of connector conductor leads 71-92 for establishing electrical connections between the printed circuit board conductor strips 11-32 and the device conductor leads 41-42. The connector conductor leads 71-92 in the preferred embodiment are made from beryllium copper.
The connector 65 of the present invention comprises a body made of suitable insulating thermoplastic material. In the exemplary embodiment, the body 95 is made from Delrin or Celcon. As shown in FIG. 2, the body 95 comprises a rectanguloid section 96 with an upper planar or flat surface 97. Projecting from the section 96 with the upper surfaces thereof aligned with the flat surface 97 are shoulders 98 and 99. The shoulders 98 and 99 extend lengthwise along the sides of the section 96.
Fixedly secured to the shoulders 98 and 99, respectively, are locking members 100 and 101, respectively. The locking members 100 and 101 project above the flat surface 97 and extend lengthwise of the section 96 in parallel relation with the shoulders 98 and 99. As shown in FIGS. 4 and 6, the locking members 100 and 101 are formed with the outer lengthwise walls thereof directed downwardly and inwardly so as to be angularly disposed relative to the shoulders 98 and 99 to form gripping or locking surfaces therewith. The shoulders 98 and 99, and the locking members 100 and 101 may be made of the same material from which the section 96 is formed and may be integrally formed therewith.
Formed in the locking members 100 and 101 along the upper walls thereof are parallel, spaced grooves to receive the connector conductor leads 71-92. Between the shoulders 98 and 99 and the section 96 are formed holes (FIG. 2) to receive the connector conductor leads 71-92 for retaining the same in fixed relation within the body 95.
The connector conductor leads 71-92 have their intermediates sections extending along the side walls of the section 96. At the device ends thereof, the connector conductor leads 71-92 project outwardly within the grooves of the locking members 100 and 101 at right angles to the intermediate sections thereof. At the printed circuit ends, the conductor leads 71-92 project outwardly at even height with the lower wall of the section 96 and at right angles to the intermediate sections thereof.
A cover or top 105 of the connector 65 is made of suitable thermoplastic material. In the exemplary embodiment, the cover 105 is made from Lexan. According to the present invention, the cover or top 105 is more flexible or has greater yieldability than does the body or base 95. The cover 105 comprises flange walls 106 and 107. Joining the flange walls 106 and 107 are confronting inwardly disposed locking walls 108 and 109, respectively, to form gripping or locking surfaces. The locking walls 108 and 109 are downwardly and inwardly directed to form lengthwise locking surfaces. The flange walls 106 and 107 are adapted to engage or confront the upper surfaces of the shoulders 98 and 99. The locking walls 108 and 109 are adapted to engage the outer walls of the locking members 100 and 101.
A reduced thickness in the cover 105 forms shoulders 110 and 111 which are adapted to engage and confront the upper surfaces of the locking members 100 and 101, respectively. A further reduced thickness in the cover 105 forms a recessed section 115.
In the use of the connector 65, the connector 65 is caused to adhere to the circuit side of the printed circuit board 10 with the printed circuit board ends of the connector conductor leads 71-92 soldered to the printed circuit conductor strips 11-32, respectively. The flat pack microelectronic device 35 is caused to seat on the fiat surface 97 of the body 95 with the device conductor leads 41-62 thereof disposed within the grooves of the locking members 100 and 101 to establish electrical connections with the device ends of the connector conductors leads 71-92, respectively without soldering or bonding.
Now, the cover 105 is placed above the body 95 with the recessed section 115 above the fiat pack microelectronic device 35 and with the locking walls 108 and 109 aligned with the locking members 100 and 101, respectively. Thereupon, the cover 105 is pressed down manually to lock the cover 105 onto the body 95 through contact press fitting. When this occurs, the locking walls 108 and 109 engage the locking members 100 and 101, respectively, the shoulders 110 and 111 engage the upper surfaces of the locking members 100 and 101, respectively, and the flange walls 106 and 107 engage the shoulders 98 and 99, respectively through the intermediation of confronting, contacting conductors.
It is to be observed from FIG. 6 that the cover 105 is bowed and is always under tension. By virtue thereof, the gripping action between the body 95 and the cover 105 is improved. To remove the cover 105 from the body 95, the central portion of the cover 105 is pressed downwardly while a lever applies an upward force to the sides thereof.
It is to be understood that modifications and variations of the embodiment of the invention disclosed herein may be resorted to Without departing from the spirit of the invention and the scope of the appended claims.
