Definitions
- This invention relates to a press fit insulator and terminal combination for mounting into printed circuit boards.
- the insulator is used to press the contact into the printed circuit board.
- Each terminal contact is press fitted by means of an intermediate press fit collar region which is engaged by a receiving insulator.
- the collar region is defined by tabs which are formed perpendicular to the longitudinal axis of the terminal contact body. Because of the perpendicularly extending tabs which form the collar region, multiple terminal contacts cannot be efficiently stamped from the same sheet of construction material.
- the intermediate press fit collar regions of the contact terminals require a two step operation for the formation thereof.
- the terminal structure including the transversely extending tabs, is formed by means of a stamping operation.
- contact terminals require a second operation wherein an opposed pair of tabs is bent at least once with respect to the longitudinal axis of the contact terminal.
- the terminal contact depicted in Figs. 14 and 15 is the only embodiment disclosed wherein multiple terminal contacts may be efficiently stamped from a single sheet of construction material, as shown in Fig. 14.
- the lower two tabs must be bent in separate operations so as to be frontally extending, as shown in Fig. 15.
- the insulator compatible with this terminal contact embodiment requires four separate shoulders to engage the press fitting edges of the four separate tabs, thereby requiring an insulator of increased complexity, as illustrated in Figs. 16 and 17.
- the contact terminal embodiment shown in Figs. 12 and 13 multiples thereof cannot be efficiently stamped from a single sheet of construction material.
- the collar region requires an additional formation step in that the frontally extending tabs must be separately bent to their final position.
- the insulator adapted to receive this contact terminal embodiment requires separate wall sections having shoulders formed therein to engage the bent frontally extending tabs, in addition to a lower portion of the insulator which undercuts an upper portion thereof to form shoulders which engage the upper transversely extending tabs of the terminal contact.
- a relatively complex insulator structure is required to engage the press fitting surfaces of the contact terminal of Fig. 12, as shown in Fig. 13. The fabrication of such a structure is inherently more costly due to the necessity of forming press fitting shoulders in each separate wall section.
- the invention is to a press fit insulator and terminal combination for a connector adapted to receive and be used as the means for press fitting a plurality of contact terminals into a printed circuit board, said insulator including a block of insulating material formed with a plurality of identical compartments along its length, said compartments having offset shoulders associated therewith and said contact terminal including first and second contact ends, and first and second intermediate regions, said first intermediate region adjacent said first contact end.

- the end walls 13 of the insulator are such that several connectors may be placed end-to-end to accommodate long printed circuit boards or the ends 13 may be adapted to receive end caps.
- Figures 2a and 2b illustrate one embodiment of a contact terminal that may be used with the insulator of Figure 1 to provide a press fit connector.
- Terminal 12 is made of several regions.
- End 34 is a contact end which is pressed through a printed circuit board and may be soldered to or connected to by a wire wrap tool.

Description
- This invention relates to a press fit insulator and terminal combination for mounting into printed circuit boards.
- In US-A-4 220 393, the insulator is used to press the contact into the printed circuit board. Each terminal contact is press fitted by means of an intermediate press fit collar region which is engaged by a receiving insulator. The collar region is defined by tabs which are formed perpendicular to the longitudinal axis of the terminal contact body. Because of the perpendicularly extending tabs which form the collar region, multiple terminal contacts cannot be efficiently stamped from the same sheet of construction material.
- The intermediate press fit collar regions of the contact terminals require a two step operation for the formation thereof. In the first step, the terminal structure, including the transversely extending tabs, is formed by means of a stamping operation. With the exception of the terminal embodiment shown in Fig. 11, contact terminals require a second operation wherein an opposed pair of tabs is bent at least once with respect to the longitudinal axis of the contact terminal.
- The terminal contact depicted in Figs. 14 and 15 is the only embodiment disclosed wherein multiple terminal contacts may be efficiently stamped from a single sheet of construction material, as shown in Fig. 14. However, in this terminal contact embodiment the lower two tabs must be bent in separate operations so as to be frontally extending, as shown in Fig. 15. Moreover, the insulator compatible with this terminal contact embodiment requires four separate shoulders to engage the press fitting edges of the four separate tabs, thereby requiring an insulator of increased complexity, as illustrated in Figs. 16 and 17.
- In the contact terminal embodiment shown in Figs. 12 and 13 multiples thereof cannot be efficiently stamped from a single sheet of construction material. Moreover, the collar region requires an additional formation step in that the frontally extending tabs must be separately bent to their final position. In addition, the insulator adapted to receive this contact terminal embodiment requires separate wall sections having shoulders formed therein to engage the bent frontally extending tabs, in addition to a lower portion of the insulator which undercuts an upper portion thereof to form shoulders which engage the upper transversely extending tabs of the terminal contact. Thus, a relatively complex insulator structure is required to engage the press fitting surfaces of the contact terminal of Fig. 12, as shown in Fig. 13. The fabrication of such a structure is inherently more costly due to the necessity of forming press fitting shoulders in each separate wall section.
- All of the terminal contact embodiments disclosed in US-A-4 220 393 have tabs which extend transversely from the main body of the terminal contact. None of the terminal contacts disclosed in said document have a press fitting area formed from the main body of the terminal contact.
- The invention is to a press fit insulator and terminal combination for a connector adapted to receive and be used as the means for press fitting a plurality of contact terminals into a printed circuit board, said insulator including a block of insulating material formed with a plurality of identical compartments along its length, said compartments having offset shoulders associated therewith and said contact terminal including first and second contact ends, and first and second intermediate regions, said first intermediate region adjacent said first contact end. The insulator has at least one shoulder formed in each said compartment. Said second intermediate region on said contact terminal comprises a flat region having at least one punched out tab which mates with the said shoulder in a said compartment when the insulator is used to press fit the terminal into a printed circuit board.
- Contrary to the prior art, the terminal contact of the present invention has a tab, having a flat press fitting surface, which is punched out of or formed from the main body of the contact terminal. Such a contact terminal configuration allows savings in the construction material required to form the contact terminal, as well as simplifying the fabrication procedure required to form the finished contact terminal.

- Illustrated in Figure 1 is one embodiment of the invention. A card
edge connector insulator 10 has a plurality ofcontact terminals 12 extending from the bottom thereof. These terminals are of the type that are press fitted into a printed circuit board (not illustrated). The insulator is used to press the terminals into the printed circuit board as hereinafter described. Theinsulator 10 has two parallel side walls 11 that are connected by transverse walls, one part of which is represented by thenumeral 19. Aslot 18 extends through the central part of the insulator and along its entire length. Theslot 18 has twoparallel side walls 15 and a plurality of equallyspaced openings 17 in theside walls 15 that extend the length of the insulator. Each side wall 11 has a beveled insideedge 16 for guiding a card into the connector, and the tops of the side walls haveopenings 14 which are the same in number and are aligned with theopenings 17 to form terminal compartments. As hereinafter illustrated, each of the compartments houses or is identified with a single contact terminal. Theend walls 13 of the insulator are such that several connectors may be placed end-to-end to accommodate long printed circuit boards or theends 13 may be adapted to receive end caps. - . Figures 2a and 2b illustrate one embodiment of a contact terminal that may be used with the insulator of Figure 1 to provide a press fit connector.
Terminal 12 is made of several regions.End 34 is a contact end which is pressed through a printed circuit board and may be soldered to or connected to by a wire wrap tool. Acompliant region 33 is the part of the terminal that is press fitted into the printed circuit board. A compliant region is a part of the terminal that will deform upon being press fitted into a printed circuit board and retains the terminal in the circuit board without extreme deformation of the hole and the board surrounding the hole into which the terminal is press fitted.Flat region 30 is designed to have a punched outtab 32.Tab 32 has a flat surface 32a which is used to press the terminal into a printed circuit board. Theflat region 30 also has two flat toppedshoulders 31 which are also used in press fitting the terminal into a printed circuit board. It is the combinedareas 32a and 31 which provide a sufficiently large surface in order to press the terminal into a printed circuit board without damaging the insulator and/or terminal.Terminal 12 has acurved spring end 35, terminating inend 35a, which is used to contact a card edge connector. - Figure 3 is a cross sectional view of the insulator of Figure 1 showing the
terminal 12 in place. The terminal is inserted from the bottom of the insulator so that thecurved end 35 extends through opening 17 into the compartment.End 35a is positioned behind inside part ofinner wall 15 to hold the terminal in position. The terminal is limited in its upward movement byvertical ribs 36. Eachshoulder 31 ofterminal 12 abuts against a bottom surface forming anoffset shoulder 36a of arib 36 to limit the upward movement of the terminal. In similar manner, it is, in part, the pressing downwardly of offsetshoulder 36a againstshoulder 31 that press fits the terminal into a printed circuit board. Side wall 11 has an offsetregion 37 with a flat top area forming an offset shoulder 37a. The area 37a is also used in press fitting a terminal into a printed circuit board. The offset shoulder 37a presses downwardly against the flat area 32a oftab 32. - Figures 4, 5 and 6 illustrate the various parts used in applying the downward force to press fit the terminal. In Figure 4 it may be observed that each terminal resides between two
transverse walls 19. Eachwall 19 has arib 36 with apressing shoulder 36a, providing two points of pressure on each side of the terminal, by pressing against the twoshoulders 31. The third pressure point is against the tab surface 32a. This is best illustrated in Figure 3. - Figure 5 illustrates the cross sectional view of the insulator without the terminal in place. Figure 6 is a partial bottom view of the insulator which illustrates the three pressing surfaces, the two
surfaces 36a, one in each transverse wall, enclosing the terminal compartment, and one in the side wall of the insulator. - A second embodiment of the invention is illustrated in Figure 7. Illustrated is a multicontact connector that may be press fitted into a printed circuit board. The
connector insulator 20 hascontact terminals 22 extending from the under side. The insulator has a plurality of sleeves or compartments into each of which a single contact is placed. The compartments are separated in the direction transverse to the length of the connector bywalls 24 which extend from the top to the bottom of the insulator. The compartments are separated along the length of the insulator bywalls 24a which also extend from the top to the bottom of the connector. Each compartment has a beveled lip around its top opening to guide a mating terminal into the compartment and into electrical connection with the terminal 22 therein. - Each insulator may be terminated at each end with a mounting
platform 25 and may have a hole 25a therein through which a screw or rivet may be placed to secure the insulator to a printed circuit board. - Figure 7 illustrates a three row connector. However, there may be one or more rows, depending upon the number of desired contacts in the connector.
- Figures 8a and 8b illustrate one embodiment of a contact terminal that may be used with the insulator of Figure 7. The terminal is an elongated metal terminal with one
end 46 suitable as either a solder terminal or a wire wrap terminal. Acompliant region 45 is press fitted into a printed circuit board to make contact with circuit patterns on the board and to hold the connector on the printed circuit board. The terminal has a flatcentral region 42 which has two punched outtabs flat regions 43a and 44a, respectively, and are used in press fitting the. terminal into a printed circuit board. - Figures 13a and 13b illustrate a second embodiment of contact terminal for use with the insulator of Figure 7. The terminal is similar to the terminal of Figures 8a and 8b except that both ends 51 and 52 are straight pin contacts. A
compliant region 53 is adjacent to contact 52 and aflat region 54 is betweencompliant region 53 andcontact 51. The flat region has twopress shoulders tab 57. Theend 58 oftab 57 is also used in press fitting the terminal into a printed circuit board using the connector insulator body. - Figures 14a and 14b illustrate another embodiment of a contact terminal. The terminal has a
straight pin contact 63 and awishbone type contact compliant region 64 and aflat region 65 including press shoulders 66 and 67 andpress tab - Each of the terminals in Figures 8a, 8b, 17a, 13b, 14a, and 14c may be used in the insulator of the present invention and variations thereof. Each terminal is a press fit terminal in respect of the fact that the insulator is used to press fit the terminal into a printed circuit board.
- Figures 9 and 11 are cross sectional views of the insulator of Figure 7. Figure 11 is the same as Figure 9 with the terminals removed. As illustrated the
sleeves 23 are separated bywalls 24. Eachwall 24 has two offsetregions region 47 is on one side of a wall and the other offsetregion 48 is on the other side. In this manner there is an offsetregion 47 and an offsetregion 48 associated with eachsleeve 23. When a terminal 22 is inserted into asleeve 23tab 44 resides in offsetregion 48 andtab 43 resides in offsetregion 47. To press fit the terminals into a printed circuit board, a downward force is asserted on the tap of the insulator.Shoulder 47a presses downward ontab surface 43a and shoulder 48a presses downward on tab surface 44a thereby press fitting the terminals into the printed circuit board (not illustrated). ' - Figure 10 is a partial cross sectional view of the side of the insulator illustrated in Figure 7. It should be noted that
sleeve 23 is tapered, being larger at the bottom and smaller at the top, and when terminal 22 is inserted intosleeve 23, theedge 50 ofterminal 20 comes into frictional contact with the side walls of the sleeves. It is the frictional forces between the two that holds the terminal in the sleeve until the insulator and the contacts are press fitted into the printed circuit board. - Figure 12 is a partial bottom view of the insulator and with Figure 11 illustrates the location of the
shoulders 47a and 48a which are used in the press fitting of theterminals 20.
