An electrical connector assembly (1) having a housing (10) and a subassembly (80) connected thereto for eliminating circuit-degrading EMI. Subassembly (80) includes a substrate (20) mounted to a frame (30). Substrate (20) comprises a rigid board with circuit traces (25,26), electrical components (28), and a pin array (22) thereby defining an electrical circuit path. Frame (30) is electrically connected to the circuit path and comprises a robust, metallic piece having locking clips (36) for electrically and mechanically attaching subassembly (80) to housing (10).

Filtered circuit connector with frame

A socket connector suitable for use in establishing interconnection to a plurality of closely spaced surface pad portions of traces on a circuit panel is disclosed. This socket connector is suitable for use with a high density single in-line memory module. The individual terminals are edge stamped from a spring metal blank and inserted in closely spaced centerlines and cavities in the housing. Insertion of a circuit panel edgewise into the connector biases the terminals outwardly with the stresses primarily confined to the plane of the spring metal blank. The terminals are inserted from above and positively retained within the housing. Low insertion forces, together with a wiping action between the terminals and the surface pad portions of traces on the circuit panel is achieved.

Low insertion force terminal for use with circuit panel

Sockets specifically adapted for burn-in testing of small outline integrated circuit components are disclosed. The multicontact sockets have terminals located in cavities oriented to receive the small outline integrated circuit leads. The terminals are located between adjacent leads and are positioned to resiliently engage the interstitial edges of the package leads, thus imparting minimal stress normal to the plane of the leads. Both surface mount and through-hole sockets are disclosed and the terminals as depicted can have a bowed leaf spring configuration or a preloaded flat terminal, arcuately deformed for retention within the housing cavities. Thus the small outline integrated circuit components can be routinely inserted into the sockets for test purposes. The sockets can also be used in a conventional manner to socket integrated circuit components such as SOICs on a printed circuit board.

Socket for integrated circuit component

A socket for stacking and interconnecting corresponding leads of two integrated circuit packages having the contacts stamped and formed in a lead frame configuration with a dielectric body molded over a portion of the terminal ends. Two contact halves are sheared from the opposite end of the terminal, one contact formed upwardly while the second contact is formed downwardly. Integrated circuit package leads can be selectively commoned by jumpering the terminal ends prior to molding the body.

Socket for stacking integrated circuit packages

An electrical connector includes a stamped and formed terminal for establishing electrical contact with a terminal post having a rectilinear cross section. The terminal has at least one resilient beam which has a contact area having an arcuate cross section. The concave surface of the arcuate cross section engages the edge of the terminal posts to provide a good electrical connection even if excess solder is deposited on the exterior of the terminal post in the vicinity of the contact region.

Resilient beam electrical terminal

DIP carrier assembly comprises carrier having support surface with apertures therethrough to channels in side and bottom of carrier into which DIP leads are formed. Terminals aligned in channels in opposed sidewalls of socket apply releasing force on carrier when DIP leads deflect contact portions of terminals. Release of resilient latch on socket causes ejection of carrier.

Dual in-line package carrier assembly

Socket for a surface mount DIP comprises a housing having two rows of elongate contacts in respective apertures extending between package receiving face and opposed mounting face. Apertures intersect channels in sidewalls of nest in package receiving face forming channels which receive feet extending laterally of package. Contacts are formed with leaf springs which engage feet in channels.

Socket for surface mount dip

Socket for receiving edge of a chip carrier substrate comprises a dielectric housing having an elongate channel interrupted by partitions having aligned U-slots which limit position of substrate. Cavities separated by the partitions receive U-shaped contacts each having a base with directly opposed arms formed upward therefrom and a flat pin formed downward therefrom and extending into respective apertures in the floor of the channel. Arms present convex rolled inside surfaces to opposed surfaces of substrate for electrical contact therewith. Floor of channel has convex portion in each cavity on which base rocks as pin deflects resiliently in chamfered lead-in to aperture to accommodate any substrate warpage. Profile of U-slot in partition prevents stressing of arms beyond elastic limit.

Edge connector for chip carrier

Electrical connector comprising housing with two rows of cavities having latch arms which retain terminals received therein and wedge means received in interstices between latch arms of adjacent rows. Wedge means cannot be fully received in interstices unless terminals are fully seated in cavities.

Connector with means for retaining terminals and verifying seating

The present invention relates to a device for securing stacked printed circuit boards together utilizing signal transferring connectors mounted on the boards. More particularly, the device includes depending pins having grooves thereon and movable latching means on the connector, said means engaging the grooves to releasably latch the board and connector together.

Latching device for securing stacked printed circuit boards together

A contact for use in printed circuit boards in which a portion thereof is split or sheared to form at least a pair of legs for insertion into an aperture in said circuit board with the adjacent legs each having a surface which face and abut each other in the shear plane therebetween and with said legs being offset with respect to each other in said shear plane. When the offset legs are inserted in an aperture in a circuit board they are forced towards each other along the shear plane with the facing surfaces experiencing a strong component of force normal to said shear plane. Such normal force in turn produces a large frictional force between said facing surfaces which, together with the spring-like force generated as the legs are forced together, produce a strong opposing force against the walls of the aperture. The foregoing structure enables the use of compliant legs having a larger total cross-sectional area with respect to a printed circuit board aperture of a given size than has heretofore been possible. Further, because of such larger cross-sectional area and the large frictional contact between the leg surfaces in the plane of shear the said legs exert a greater force against the wall of the printed circuit board hole without damaging said wall than obtainable with prior devices, thereby creating both an improved electrical contact and an improved mechanical contact. In some embodiments of the invention means are provided to control the direction and amount of rotation of the legs as they are inserted into the printed circuit board aperture.

Contact with split portion for engagement with substrate

A tool set for installing and removing individual connector pins mounted in an electrical circuit board and the like and within a connector housing wherein the pin to be removed or installed is part of a row of pin pairs enclosed within a housing. A pin is installed and/or removed with the present tools without housing removal or disturbing of other pins within the housing, regardless of the type of pin damage encountered. There is also a tool for inserting tie pins in a circuit board in aligned relationship.

Tool for installing individual pins in printed circuit board

A circuit board connector having a plurality of pairs of contacts arranged in a row and with each contact having a 'C' shaped portion. Each pair of contacts is mounted securely at first ends thereof in a circuit board with the backs, or closed sides, of the 'C' shaped portion facing each other and designed to receive the edge of a second circuit board inserted therebetween. The free end of each contact has an ear-like element extending outwardly from the board to which the contacts are secured. A connector housing fits over the pairs of contacts after they have been secured in the board. Inside the housing tabs are provided, behind which tabs the ears of the contacts are positioned, thereby prestressing each pair of contacts apart. The housing is also designed so that the side walls thereof press against a dimple or finger-like tang formed near the base of each contact, thereby forcing the contacts of each pair of contacts together and further enhancing the prestressing of each pair of contacts.

Circuit board connector

A machine and a method for applying a solder resistant material or solder resist to predetermined portions of miniature connector structures are disclosed. The machine permits large numbers of the miniature connector structures to be precisely treated with the solder resist without the need for costly and time consuming masking procedures. More particularly, the miniature connector structures attached to a carrier strip are fed through a hybrid fluid dispensing assembly similar to a bath, which is continuously supplied with the solder resistant material. The quantity of material supplied to the hybrid fluid dispenser or bath is coordinated with the speed at which the miniature connector structures are driven through the bath so that each of the miniature structures absorbs a predetermined amount of solder resistant material by capillary action. The quantity of material absorbed by each of the miniature connector structures is controlled so that it is just sufficient to fill a desired area. The filled connectors are subsequently heated to cure the solder resistant material.
