Description
CA 02241~07 1998-06-22 FLAT CONNECTOR FOR ELECTRICAL PLUG-IN CONNECTIONS
Background of the Invention:
Field of the Invention:
The invention relates to a flat connector for electrical plug-in connections, which is formed with a contact blade and an attachment/connection region extending in longitudinal alignment with the contact blade, the flat connector being self-supportingly attachable and electrically connectable to a surface member, such as an underlying surface member, which is disposed transversely thereto.
In such electrical plug-in connectlons, flat plug-in contact members are often formed with a flat, rectilinear contact blade which is attached by an attachment/connection region thereof self-supportingly to a surface member extending transversely thereto, such as an underlying surface member which, for example, is formed on a printed circuit board serving inter alia as a contact carrier. Such flat plug-in contact members are generally referred to, and therefore also referred to hereinbelow, as flat connectors or plugs (German Industrial Standard 46 244). Flat connectors have heretofore been attached and connected to a printed circuit board by soldering. In this case, the flat connectors are manually CA 0224l~07 l998-06-22 plugged together with appliances and subsequently soldered.
The plugging in and soldering of the flat connectors is consequently very labor-intensive in terms of manual labor and, therefore, also expensive. What is more, with the constantly increasing complexity of printed circuit boards, the soldering represents an ever-increasing risk with respect to quality. For this reason, continuous process and quality control is also required.
Conventional types of flat connectors are the type which extends at an angle away from a contact blade and the straight type, both of which types are provided with two soldering connector or terminal pins and are attached in a self-supporting manner to a printed circuit board by inserting the connector or terminal pins into corresponding holes formed in the printed circuit board, and soldering the pins to the circuit board. Furthermore, the published European Patent Document EP 0 717 468 A2 discloses a plug-in connection formed of spring contact strips and blade strips wherein the blade contacts are formed as flat plug-in contact elements extending away at an angle therefrom and accommodated in an insulator of the blade strips, i.e., not free-standing in a housing, and are provided with press-in pins in the attachment and connection region extending away at an angle from the contact blades.
CA 0224l~07 l998-06-22 Summary of the Invention:
It is accordingly an object of the invention to provide a flat connector for electrical plug-in connections for a straight and self-supported flat connector of the type mentioned at the introduction hereto, which is relatively simply and reliably attachable to and is capable of establishing electrical contact with an underlying surface member.
With the foregoing and other objects in view, there is rovided, in accordance with the invention, a flat connector for electrical plug-in connections, the connector being formed with a contact blade and an attachment/connection region extending in longitudinal alignment with the contact blade, and being self-supportingly attachable and electrically connectable to a surface member disposed transversely thereto, comprising at least two contact zones provided in the attachment/connection region of the flat connector for effecting a solder-free plug-in connection at the transversely disposed surface member, the flat connector being formed with lateral projections between the attachment/connection region and the contact blade, at mutually opposite flat sides of the connector, the lateral projections protruding beyond the width of the contact blade and forming a shoulder at a side thereof facing away from the transversely disposed surface member for setting thereon a press-in tool, and forming a press-in stop CA 0224l~07 l998-06-22 at a side thereof facing towards the transversely disposed surface member.
In accordance with another feature of the invention, the contact zones are formed as pin-shaped press-in connections.
In accordance with a further feature of the invention, the contact zones are of solid construction.
In accordance with an added feature of the invention, the contact zones have resilient press-in sections.
In accordance with yet another feature of the invention, a section of the flat connector having lateral projections is formed with at least one cutout therein.
In accordance with yet a further feature of the invention, the flat connector comprises a punched-out sheetmetal part, the cutout being punched out of the sheetmetal part.
In accordance with yet an added feature of the invention, the cutout has a rectangular shape and a longitudinal axis extending transversely to a direction in which the flat connector is plugged in.
CA 0224l~07 l998-06-22 In accordance with a first alternative feature of the invention, the cutout is shaped as a slot having a longitudinal axis extending transversely to a direction in which the flat connector is plugged in.
In accordance with a second alternative feature of the invention, the cutout is shaped as an ellipse having a longitudinal axis extending transversely to a direction in which the flat connector is plugged in.
In accordance with a third alternative feature of the invention, the cutout is shaped as a triangle.
In accordance with a fourth alternative feature of the invention, the cutout has a circular shape.
In accordance with a concomitant feature of the invention, the cutout extends in a direction transverse to a plug-in direction of the flat connector substantially over a center spacing between the contact zones.
Such a straight flat connector can be introduced by the contact zones thereof into holes formed in an underlying surface member, for example, of a contact carrier in the form of a printed circuit board, in a relatively simple manner by CA 0224l~07 l998-06-22 pressing or plugging it in, and is then attached to the underlying surface member as a self-supporting or free-standing contact. In the condition wherein the contact zones are pressed into the holes formed in the underlying surface member, for example, into the metallized bores of a printed circuit board, the contact zones provided for effecting a solder-free press-in connection produce a secure and permanent electrical connection to the underlying surface member. The attachment and contacting of a flat connector according to the invention can therefore be realized quickly, inexpensively and in a reliable manner.
As noted hereinbefore, with regard to such a flat connector, it is expedient for the contact zones to be formed as pin-shaped press-in connections.
With regard to required holding or retaining forces when the flat connector is used as a self-supporting or free-standing contact without a housing enclosure, it is advantageous if the contact zones are solidly formed. In principle, however, it is also possible and, in many cases, no doubt adequate as well for the contact zones to have resilient press-in sections.
With regard to such flat connectors, in the condition wherein they are attached to the underlying surface member, stresses often occur on the press-in connections via the contact blade CA 0224l~07 l998-06-22 and consequently act upon the attachment and the electrical connection. It is therefore advantageous if, in the case of a flat connector according to the invention, the section or portion of the flat connector formed with the lateral projections is provided with at least one cutout or recess.
In the case of a flat connector comprising a punched-out sheetmetal part, such a cutout is formed by a punched-out opening and, for example, has a rectangular shape. The geometrical construction is not confined to a rectangular shape, however, but rather, different geometrical shapes are possible for the cutout or cutouts, as noted hereinafter. In any event, such a cutout or cutouts formed in the section or portion of the flat connector having the lateral projections provides a predetermined or set bending point, i.e., when there are flexural forces acting upon the contact blade, for example, transversely to the plug-in direction, the moment of resistance at the set or predetermined bending point formed by the cutout or cutouts is too small to be able to loosen the press-in connection because of the reduction in cross-section.
Instead, such flexural forces are absorbed at the predetermined or set bending point, which leads to a re-forming or deforming of the flat connector, the contact blade of which is then bent out of the plug-in direction. The press-in connection is not loosened, however, i.e., the set or predetermined bending point produced by the cutout or cutouts forms a protection against loosening for the press-in CA 0224l~07 l998-06-22 contacting and consequently ensures the contacting of the connectors or terminals. When straightening bent flat connectors, the predetermined or set bending point likewise ensures that, in a reversal of the effect described, the press-in contact is preserved. In this respect, it has been confirmed by tests that the bending cycles required in the German Industry Standard (DIN) IEC 352 (= simulation of the straightening of bent connectors) are reliably achieved.
Other features which are considered as characteristic for the invention are set forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a flat connector for electrical plug-in connections, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, wherein:
CA 0224l~07 l998-06-22 Brief Description of the Drawings:
Fig. 1 is a side elevational view of a preferred embodiment of a flat connector according to the invention, attached to an underlying surface memberi and Figs. 2 to 6 are reduced views of the flat connector of Fig. 1 showing respective bending locations thereof formed with different geometrical shapes.
Description of the Preferred Embodiments:
Referring now to the figures of the drawings, the flat connector 1 preferably is formed of a punched-out part of sheet metal and has a flat contact blade 2, usually extended angularly away at a free end thereof, and provided with an engagement hole 12 formed in the middle longitudinal axis thereof. The flat connector 1 also has an attachment and connection region 3 extending in the longitudinal direction in alignment with the contact blade 2 for attaching the consequently straight flat connector 1 in a self-supporting or free-standing manner to an underlying surface member, for example, a printed circuit board 4, and can be electrically connected in contact lined or plated holes formed in the printed circuit board. For this purpose, at least two contact zones 5 and 6 are provided for a solder-free press-in connection, in the attachment and connection region 3 of the flat connector 1, the contact zones 5 and 6 being expediently CA 0224l~07 l998-06-22 constructed as press-in connections in the form of pins. The contact zones 5 and 6 may be solidly formed or have resilient press-in portions. To be able to press the flat connector 1 into the printed circuit board 4 in an efficient manner with simple press-in tools, the flat connector 1 is formed between the attachment and connection region 3 and the contact blade 2, on both mutually opposite flat sides of a part A having lateral projections 7 and 8 which protrude over the width of the contact blade 2. The projections 7 and 8 form a shoulder 9 on the upper side thereof, as shown in the figures, the shoulder 9 thus facing away from the underlying surface member 4 and providing a location upon which a press-in tool may be set, the projections 7 and 8 being further formed with a press-in stop 10 on the underside thereof facing towards the underlying surface member, as shown in the figures. Moreover, the section A formed with the lateral projections is provided with a recess or cut-out 11, llb, llc, lld, lle, respectively, in Figs. 1 and 3 to 6, or several recesses lla in Fig 2, located beyond or outside the insertion or contact region of the contact blade 2 and, in a preferred manner, as close as possible to the attachment and connection region 3. The recess or recesses 11 and lla to lle serve for protecting the press-in contacting against loosening and for maintaining the contacting during the straightening of bent flat connectors by preferably reducing the cross-section of the flat connector considerably at the section A thereof, the recess or CA 0224l~07 l998-06-22 cut-out 11 or llb to lle or the recesses or cut-outs lla providing a predetermined bending location which, when flexural forces occur, has a moment of resistance which is too small to be able to loosen the press-in contacting and which, in the case of such stresses, leads in a desired manner to a bending at a specific location of the flat connector, without adversely affecting the press-in connection and contacting.
When the flat connector 1 is formed of a punched or stamped-out sheetmetal part, as shown in the embodiment of Fig. 1, the cutout 11 is produced by punching an opening therein preferentially having a rectangular shape and extending transversely to the direction in which the flat connector 1 is plugged in. In this regard, as also in regard to the other embodiments of the invention as shown in Figs. 2 to 6, the cutout 11 and llb to lle, as well as the cutouts lla, extend in the direction transverse to the plug-in direction of the flat connector 1 approximately over the center spacing m between the contact zones 5 and 6.
The embodiments of the flat connector according to the invention shown in Figs. 3 to 6 differ from the embodiment in Fig. 1 merely by the geometrical shape of the respective cutout llb to lle, and the embodiment of Fig. 2 both by the fact that more than one cutout is provided and by the overall geometrical shape of the provided cutouts lla. Thus, in Fig.
CA 0224l~07 l998-06-22 2, in the aforedescribed sense, three very small circular cutouts lla are provided, which likewise produce, in the section A, a reduction in cross-section adequate for a set or rated bending point. This is realized in Fig. 3 by a single larger cutout or recess llb having a circular shape. In Figs.
4 and 5, the respective cutout or recess llc, lld has the shape of a slot and an ellipse, respectively, extending transversely to the plug-in direction of the flat connector 1.
Finally, the cutout lle in Fig. 6 is formed as a triangle.
Polygonal shapes for the cutouts are also conceivable. In any event, a reduction in cross-section adequate for a predetermined or rated bending point at a specific location of the flat connector 1 is achieved by the cutout or cutouts arranged symmetrically with respect to the central longitudinal axis of the flat connector.

Fig. 1 is a side elevational view of a preferred embodiment of a flat connector according to the invention, attached to an underlying surface memberi and Figs. 2 to 6 are reduced views of the flat connector of Fig. 1 showing respective bending locations thereof formed with different geometrical shapes.
Description of the Preferred Embodiments:
Referring now to the figures of the drawings, the flat connector 1 preferably is formed of a punched-out part of sheet metal and has a flat contact blade 2, usually extended angularly away at a free end thereof, and provided with an engagement hole 12 formed in the middle longitudinal axis thereof. The flat connector 1 also has an attachment and connection region 3 extending in the longitudinal direction in alignment with the contact blade 2 for attaching the consequently straight flat connector 1 in a self-supporting or free-standing manner to an underlying surface member, for example, a printed circuit board 4, and can be electrically connected in contact lined or plated holes formed in the printed circuit board. For this purpose, at least two contact zones 5 and 6 are provided for a solder-free press-in connection, in the attachment and connection region 3 of the flat connector 1, the contact zones 5 and 6 being expediently CA 0224l~07 l998-06-22 constructed as press-in connections in the form of pins. The contact zones 5 and 6 may be solidly formed or have resilient press-in portions. To be able to press the flat connector 1 into the printed circuit board 4 in an efficient manner with simple press-in tools, the flat connector 1 is formed between the attachment and connection region 3 and the contact blade 2, on both mutually opposite flat sides of a part A having lateral projections 7 and 8 which protrude over the width of the contact blade 2. The projections 7 and 8 form a shoulder 9 on the upper side thereof, as shown in the figures, the shoulder 9 thus facing away from the underlying surface member 4 and providing a location upon which a press-in tool may be set, the projections 7 and 8 being further formed with a press-in stop 10 on the underside thereof facing towards the underlying surface member, as shown in the figures. Moreover, the section A formed with the lateral projections is provided with a recess or cut-out 11, llb, llc, lld, lle, respectively, in Figs. 1 and 3 to 6, or several recesses lla in Fig 2, located beyond or outside the insertion or contact region of the contact blade 2 and, in a preferred manner, as close as possible to the attachment and connection region 3. The recess or recesses 11 and lla to lle serve for protecting the press-in contacting against loosening and for maintaining the contacting during the straightening of bent flat connectors by preferably reducing the cross-section of the flat connector considerably at the section A thereof, the recess or CA 0224l~07 l998-06-22 cut-out 11 or llb to lle or the recesses or cut-outs lla providing a predetermined bending location which, when flexural forces occur, has a moment of resistance which is too small to be able to loosen the press-in contacting and which, in the case of such stresses, leads in a desired manner to a bending at a specific location of the flat connector, without adversely affecting the press-in connection and contacting.
When the flat connector 1 is formed of a punched or stamped-out sheetmetal part, as shown in the embodiment of Fig. 1, the cutout 11 is produced by punching an opening therein preferentially having a rectangular shape and extending transversely to the direction in which the flat connector 1 is plugged in. In this regard, as also in regard to the other embodiments of the invention as shown in Figs. 2 to 6, the cutout 11 and llb to lle, as well as the cutouts lla, extend in the direction transverse to the plug-in direction of the flat connector 1 approximately over the center spacing m between the contact zones 5 and 6.
The embodiments of the flat connector according to the invention shown in Figs. 3 to 6 differ from the embodiment in Fig. 1 merely by the geometrical shape of the respective cutout llb to lle, and the embodiment of Fig. 2 both by the fact that more than one cutout is provided and by the overall geometrical shape of the provided cutouts lla. Thus, in Fig.
CA 0224l~07 l998-06-22 2, in the aforedescribed sense, three very small circular cutouts lla are provided, which likewise produce, in the section A, a reduction in cross-section adequate for a set or rated bending point. This is realized in Fig. 3 by a single larger cutout or recess llb having a circular shape. In Figs.
4 and 5, the respective cutout or recess llc, lld has the shape of a slot and an ellipse, respectively, extending transversely to the plug-in direction of the flat connector 1.
Finally, the cutout lle in Fig. 6 is formed as a triangle.
Polygonal shapes for the cutouts are also conceivable. In any event, a reduction in cross-section adequate for a predetermined or rated bending point at a specific location of the flat connector 1 is achieved by the cutout or cutouts arranged symmetrically with respect to the central longitudinal axis of the flat connector.
