Description

Connector assembly for printed circuit boards

Field of the invention

The invention relates to an electrical connector assembly for connecting a printed circuit board, a

Contact bridge insert for insertion into the printed circuit board, the printed circuit board equipped with the contact bridge insert and the use of the contact bridge insert for such a connector assembly.

Background of the invention

Bus plug as part of terminal blocks with

intelligent electronics are known. These are used, among other things, to connect sensors and actuators. Such bus plugs contain two contact springs per pole, between which a circuit board is inserted to contact the tracks on the circuit board.

Typically, the two contact springs are independent of each other and are not electrically connected directly to each other. The circuit board typically has two

Functions, namely the tapping of the signals or the voltage and establishing an electrical connection between the two individual contacts. For example, reference is made to the DIN rail connector with electronics housing ME 22.5 TBUS 1.5 / 4P1S KMGY - 2201732 from Phoenix Contact (see the product catalog from Phoenix Contact

"Electronics Housing 2014/2015", page 35).

General description of the invention

If desired, the two contact springs

It would be conceivable to provide a common contact element, which is punched as a one-piece metal part and is shaped and so the two contact springs are integrally connected as part of the same metal part. However, this would be accompanied by major changes to the terminal block. Such changes to the

Terminal blocks are in turn typically with a

Change the manufacturing tools connected and are therefore complex and costly.

It is therefore an object of the invention to provide an electrical connector assembly for connecting a printed circuit board which has an electrical connector

Loop-through connection between the two contact springs without or with only slight changes of the

Connector allows.

Another aspect of the object of the invention is to provide an electrical connector assembly for connecting a

PCB ready to provide, which optionally allows a loop-through connection between the two contact springs, which is easy and inexpensive to implement, reliable and flexible customizable to customer requirements.

A particular aspect of the object of the invention is to provide an electrical connector assembly for connecting a printed circuit board with a loop-through connection between the two contact springs, in which the

Normal force of the contact springs as independent as possible of variations in the PCB thickness. The object of the invention is solved by the subject matter of the independent claims. Advantageous developments of the invention are defined in the subclaims. According to the invention, an electrical connector assembly for directly connecting a printed circuit board

provides. The connector assembly for direct

Connecting the circuit board includes an electrical connector and the plug-in into the connector

PCB. The printed circuit board is in particular a printed and equipped with electronic components

Circuit board, which is sometimes referred to as a printed circuit board or PCB (printed circuit board).

The printed circuit board has a first and a second flat side, which can also be referred to as the front or rear side. The printed circuit board has, in particular printed circuit traces and electronic components on at least one of the two flat sides, possibly also on both flat sides. The printed circuit board is preferably constructed using SMD technology.

The electrical connector has an insulating

Connector housing, preferably a plastic connector housing, which has a housing opening, in which the circuit board frontally with a

Edge area can be inserted. Furthermore, the electrical connector has a first and a second

Contact spring, which are housed in the connector housing. When the circuit board is inserted into the connector, it slides between the two contact springs, and in the fully inserted state, the inserted edge region of the circuit board is clamped or frictionally held on both sides by the first and second contact spring, wherein the first and second contact spring in With respect to the circuit board opposite. At the same time, the metallic contact springs also serve to make electrical contact with the printed circuit board. In other words, the first and second contact spring come to rest on both sides of the printed circuit board and exercise due to the deflection perpendicular to the plane of the circuit board against the

Spring preload one, defined as possible, normal force for contacting the circuit board. The too

contacting trace thus extends into the edge region of the circuit board, more precisely to the

associated contact spring. Preferably, the first and second contact springs of a first and second,

in particular U-shaped, metallic contact element formed, which allows an individual adjustment of the distance between two connectors.

However, the corresponding contact spring is now

in particular not - or at least not exclusively - directly to the conductor to be contacted on, but it is a separate electrically conductive

Contact bridge insert provided for contacting, on which the contact spring is applied to the electrical

Make contact. For this purpose, the circuit board in the inserted into the housing opening edge region a

Through hole on the conductor track to be contacted and the contact bridge insert is inserted into the passage opening, such that in the inserted state of the circuit board, the first contact spring rests against the first side of the contact bridge insert and this with the

Clamping force applied and electrically contacted directly. On the other hand, the contact bridge insert is electrically connected to the conductor track to be contacted, In particular, the contact bridge insert is soldered onto the conductor track to be contacted.

Furthermore, the contact bridge insert extends through the passage opening and is acted upon on the first side opposite the second side of the second contact spring with the clamping force and

electrically contacted directly. In other words, the contact bridge insert is electrically and mechanically contacted by the first contact spring on the first side and by the second contact spring on the second side, so that the contact bridge insert is held in a clamping and electrically directly contacting manner by the first and second contact spring.

Thus, the contact bridge insert not only causes the two-sided direct contact by the two contact springs, but also simultaneously produces an electrical loop-through connection between the first and second contact spring when the circuit board is inserted into the connector.

An advantage of the invention is that this electrical

Loop-through connection independent of the conductor track guidance and the electronic assembly of the printed circuit board

can be accomplished.

It is also advantageous if the first and second

Contact spring on the opposite sides of the

Contact bridge insert abut and be in electrical and mechanical contact with the contact bridge insert, since thus the deflection of the first and second contact spring defined normal force of the thickness of the

Contact bridge insert is determined and is independent of the thickness of the circuit board. This is particularly advantageous since printed circuit boards can typically have relatively large thickness tolerances and the

Contact bridge insert with a lower tolerance can be produced. This ensures an increased contact quality.

It can be seen that the connector may have a plurality of pairs of first and second contact springs, which contact a plurality of juxtaposed conductor tracks and by means of one each

Loop through the contact bridge insert through the printed circuit board. The circuit board can be between the

Tracks have slots so that the

Circuits extend on protrusions or fingers of the circuit board, which are inserted into the connector. In this case, the housing opening with partitions

be divided, which engage in the PCB slots between the projections. However, the circuit board may also have a straight end for insertion into the connector.

The invention advantageously makes it possible to choose without or with only minor adjustments of the connector or connector housing

create, whether the tracks should be looped through or not. This can be determined by the customer himself and only needs to adapt the design of the circuit board, which can be less expensive and less expensive than new tools for the production of modified

To provide connectors. The user can in Advantageously, even selectively select selectively for each trace whether a loop-through connection

is created or not, by simply to the

desired conductor tracks provided the passage opening and a contact bridge insert is used, and on the conductor tracks where no looping connection

is desired, the conductor remains as usual without

Contact Bridge application. Thus, the invention provides the user with flexible design options by adapting only the circuit board design and without or with only minor changes in the connector.

The connector is preferably a bus plug or

Bus connector, e.g. for connecting actuators or sensors, in particular a bus connector in one

Type in which several bus connectors are connected in a chain like a chain. Here are the associated

Contact springs of the plurality of juxtaposed bus connectors with each other, i. successively contacted by a bus connector to the next bus connector. In particular for this purpose is the loop-through connection

between the respective first and second contact springs within the bus connector advantageous, since thus a loop-through connection of the respectively associated

Contact springs can be created due to the looping through bus connector to bus connector between all bus connectors.

The contact bridge insert is preferably as a sheet metal stamped and formed metal element

educated. This is easy and inexpensive in large Numbers can be produced and the shape can be easily adapted to the conditions.

Preferably, the contact bridge insert is made of a

Metal sheet of copper or a copper alloy punched and shaped, which has the advantage of high conductivity. The relatively low hardness of copper or

Copper alloys, possibly against the

Use of copper or copper alloys may be acceptable in the present invention, inter alia, by choosing a suitable shape.

It has been found that a thickness of the metal sheet between 0.1 mm and 0.5 mm, preferably a thickness of 0.2 mm +/- 0.1 mm, is suitable for at least three

To meet requirements. First, the thickness

especially in connection with a suitable

Shaping - even when using copper or

Copper alloys - still sufficient to withstand the normal force of contact springs; secondly, the

Contact bridges as little as possible; and third, they are light enough to be used with a vacuum pipette in a standard SMD placement process.

The contact bridge insert is preferably as

SMD component formed. This has the advantage that it can be automatically equipped with the already existing electronic SMD components of the circuit board with a vacuum pipette. The size of the

Contact bridge insert is adapted to the conditions of the SMD assembly and it fits into conventional blister straps for SMD assembly. Preferably, the contact bridge insert is soldered to the at least one conductor track. Advantageously, the soldering together with the already existing

electronic circuit board SMD components are made, so that the insertion and soldering of the

Contact elements in the SMD assembly process without

considerable additional effort can be integrated.

According to a preferred embodiment, the

Contact bridge insert on a flat solder and contact plate, which is wider than the through hole and can be soldered in the inserted edge region of the circuit board on the first or second flat side with the at least one conductor track. This facilitates the

Positioning on the associated trace.

Preferably, the thickness of the circuit board in the region of the contact bridge insert is partially reduced and the

Conductor extends to the thickness-reduced area and is there soldered to the flat solder and contact plate of the contact bridge insert. This has the advantage that the contact bridge insert on the soldered side does not apply, but that the flat solder and

Contact plate is substantially flush with the remaining non-thickness-reduced flat side of the circuit board runs. As a result, an undesirable excessive change in the deflection of the contact springs is avoided, so that the

Force relationships of the previous spring design are preserved. Furthermore, the insertion into the connector is facilitated. The inserted end face of the printed circuit board is - as usual - preferably bevelled and the flat solder and contact plate is preferably in an angled free end portion of the contact bridge insert over. Of the

angled free end portion extends at least a piece at the tapered end of the

PCB, he can e.g. be bent at an angle and nestle against the beveled end face. In

Advantageously, thereby the positioning of the contact bridge insert in the through hole can be facilitated within the usual tolerances.

According to a preferred embodiment of the invention, the contact bridge insert comprises in a side view a ring section bent into a flattened ring. This ring portion is slightly narrower than the passage opening and can be easily inserted into the preferably elongate passage opening. For this purpose, the ring portion is also narrower than the flat solder and contact plate. Such a molded contact bridge insert can be easily formed from an elongated stamped sheet metal strip, which is punched with different width sections. The flat solder and contact plate defines one

Contact surface on which the associated contact spring comes to rest in order to establish the electrical contact between the contact spring and the contact bridge insert, and one of the contact surface opposite and

PCB facing back. When a large force is applied, the narrow end of the sheet metal strip terminating in the bent ring portion can be frontally and preferably perpendicularly supported on the back of the planar solder and contact plate to give the ring portion a greater stability. The ring portion thus preferably has two flat contact plates, namely the solder and contact plate and a mating contact plate, which form the first and second contact surface for the first and second contact spring. At one of the two narrow ends of the ring section are the solder and

Contact plate and the mating contact plate by means of a curved portion integrally connected to each other and at the other of the two narrow ends of the ring portion is a support leg angled from the contact surface, and the support leg can be supported at high force with its terminating end on the back of the solder and contact plate. This embodiment allows the use of relatively soft and relatively thin

Sheet metal, since the ring section thus formed can still have a sufficiently high stability against the normal forces of the contact springs. If that is

terminating narrow end in the area of soldering and

Contact plate of the contact bridge insert is supported and the solder and contact plate is soldered in the installed state stable with the conductor track, can of the

Contact springs exerted forces particularly well received.

A particular advantage of the invention is given when the contact bridge insert, in particular the curved ring portion to the flattened ring has a height, ie extension in the direction transverse to the circuit board, which is always slightly larger regardless of tolerance variations in the thickness of the circuit board, as the thickness of PCB. As a result, the deflection and thus the normal force of the contact springs regardless of tolerance variations in the circuit board thickness is no longer determined by the thickness of the

PCB, but by the height of the

Contact bridge inserts determined, which can be prepared in an advantageous manner with lower tolerance.

A typical tolerance of the thickness of the printed circuit board is in fact +/- 10%. The height of the curved to the flattened ring ring portion of the contact bridge insert, however, with a tolerance of not greater than +/- 5%, preferably even not greater than +/- 2.5%

getting produced. To achieve this, the

Contact bridge insert after bending preferably pressed to size, with the desired tolerances can be achieved in an advantageous manner.

The invention also provides the printed circuit board, prepared for insertion into the housing opening of the connector as part of the connector assembly, in particular with the advantages described above

Properties of the contact bridge insert. The

inventive circuit board comprises a

Through opening in the in the housing opening

pluggable edge area of the circuit board and in the

Through hole is a contact bridge insert used to establish the electrical loop-through connection between the first and second contact spring when the circuit board is inserted into the connector.

In general, it can be seen that the phrase "includes a through hole" and "includes a Contact bridge use "is open to understand and

Of course, several through holes and contact bridge inserts can be present. Preferably, even a plurality of through holes and a plurality of contact bridge inserts are present, wherein in each case one through opening in each case one

Contact bridge insert is inserted.

Another object of the invention is the

Contact bridge insert, prepared for insertion into the through hole in the printed circuit board as part of

Connector assembly, in particular with the above

described preferred features for producing an electrical loop-through connection between the first and second contact spring when the contact bridge insert is inserted in the through hole of the circuit board and the circuit board is inserted into the connector.

Another object of the invention is the use of one or more of the contact bridge inserts in the

Connector, wherein the conductor tracks on the circuit board selectively provided with through holes and the

Contact bridge inserts are inserted into the through holes of the circuit board to be selective

Loop-through connections between selected pairs of first and second contact springs, i. there and only where the user desires to produce, if the

PCB is inserted into the connector. In the following the invention is based on

Contact element pairs of three connected connectors. Detailed description of the invention

Referring to Figs. 1 and 2, the connector 10 is formed in this example as a bus connector or bus connector and has a connector housing 12 from

Plastic with a housing opening 13, in which a circuit board 20 with its Einsteckrandbereich 22nd

is inserted. In Fig. 1, the connector 10 is shown cut open at the front left corner, so that the respective U-shaped and at least partially housed by the plastic connector housing 12 first and second contact element 28, 30 and the

Contact bridge insert 40 for contacting a conductor track 26 of the printed circuit board 20 are partially visible. The first contact element 28 comprises a stamped out and shaped first contact spring 32 and the second contact element 30 comprises a punched out and formed second

Contact spring 34 between which the circuit board 20 is clamped and electrically contacted. The connector 10 has a total of a plurality of further first and second juxtaposed contact elements 28, 30 - in this example a total of four - to each contact a conductor track 26.

Referring to FIG. 3, the circuit board or

Board 20 in the Einsteckrandbereich 22 four contact fingers 24, on which the conductor tracks 26 extend. The contact fingers 24 are separated from each other by slots 23 in the printed circuit board 20. The two left-hand fingers 24 have oblong milled-through openings 36, which are essentially oval in this example, into each of which a contact bridge insert 40 is inserted. In the

Representation of Fig. 3 is the left contact bridge insert 40 already inserted into the passage opening 36,

whereas second seen from the left

Contact bridge insert 40 is still to be used. Of the

Edge region 22 of the printed circuit board 20, more precisely the fingers 24, are in the region of the respective through-hole 36, i. where the contact bridge inserts 40 are used to the thickness of the metal sheet from which the

Contact bridge inserts 40 are thinned out so that the front first contact surface 40a of the contact bridge inserts 40 runs flush with the front side 20a of the printed circuit board 20.

Referring to Figs. 3 to 8 is the

Contact bridge insert 40 is punched and shaped as a metal strip from a thin metal sheet. Of the

Contact bridge insert 40 has a soldering and contact plate 42, by means of which the contact bridge insert 40 is soldered to the associated conductor track 26 and at which the first contact spring 32 comes to rest. The soldering and contact plate 42 merges integrally into an oblong oval ring section 44, which can be inserted into the passage opening 36. The planar solder and contact plate 42 has a greater width B than the width b of the

Ring section 44 so that the solder and contact plate 42 comes to lie on the conductor track 26 around the passage opening 36 around. The ring portion 44 includes a

semicircular arc section 46, the soldering and

Contact plate 42 integrally connects with the mating contact plate 48. The mating contact plate 48 forms the second contact surface 48a on which the second contact spring 34 comes to rest. From the flat counter-contact plate 48 is perpendicularly a support leg 50 angled, which is attached to the inside 42b of the solder and contact plate 42 can be supported. At the junction between the solder and contact plate 42 and the arcuate portion 46, the metal strip from which the contact bridge insert 40 is made tapers at location 52. Thus, the elongate ring portion 44 is tapered from a portion of the solder and contact plate 42, arc portion 46 , the counter contact plate 48 and the

Support leg 50 formed as a ring open at one point.

At the opposite of the ring portion 44

terminating end of the solder and contact plate 42, this is integrally connected to an angled at about 45 ° free end portion 54.

The elongate ring portion 44 is inserted by the user into the specially created through opening 36, the soldering and contact plate 42 comes to lie on the thinned portion of the associated finger 24 and there with the conductor track 26, which extends to the thinned area 25, is soldered. The free obliquely angled end portion 54 rests against the tapered end 21 of the circuit board 20 and serves for the longitudinal positioning of the contact bridge insert 40 in the passage opening 36, which is milled as a slightly larger slot.

It can be seen particularly clearly in FIG. 8 that the first contact surface 42a of the soldering and contact plate 42, on which the first contact spring 32 abuts, runs flush with the undiluted part of the printed circuit board 20. The printed circuit board 20 has a nominal thickness d of 1.02 mm and is thinned in the present example

Area 25 thinned out by 0.2 mm, which corresponds to the preferred thickness of the metal sheet of 0.2 mm, from which the contact bridge insert 40 is punched and formed. The height h of the contact bridge insert 40 is in this example 1.2 mm and is after punching and shaping to size

pressed. This allows a tolerance of the height h of

Contact bridge insert 40 to +/- 2.5%. The tolerance of the thickness of the circuit board 20 is usually +/- 10%, so that the board thickness within the tolerance between 0.92 mm and 1.12 mm

can vary. Thus, the counter contact plate 48 is at least a supernatant even at maximum PCB tolerance on the back 20b of the circuit board 20

U = 0.08 mm over. This has the advantage that the deflection of the contact springs 32, 34 varies less than when

only a standard circuit board would be plugged.

Thus, the normal force with which the contact springs 32, 34, the contact with the first contact surface 42 a of

Solder and contact plate 42 and the second contact surface 48 a of the mating contact plate 48 produce, more constant than if only a conventional circuit board would be inserted. As can be seen in Figs. 6 to 8, the forms

Contact bridge insert 40 a direct electrical

Contact bridge between the first contact spring 32 and the second contact spring 34, so that an electrical

Loop through connection between the two contact springs 32, 34 is made, regardless of the

Tracks of the circuit board 20 and without the two Contact elements 28, 30 would otherwise be connected to each other.

Referring to FIG. 9, any number of the bus plugs 10 may be lined up with each other, with first and second contact elements 28, 30 of adjacent bus plugs 10 being electrically connected to each other. The first contact element 28 has at its the first

Contact spring 32 opposite side of the U-shape, an outer contact surface 66, and the second contact element 30 has at its second contact spring 34th

opposite side of the U-shape on an outer bus contact spring 68. The outer bus contact spring 68 and the outer contact surface 66 are from outside the

Connector housing 12 accessible and the outer bus contact spring 68 and the outer contact surface 66 of each adjacent and interconnected bus plugs 10 are in contact with each other to a chain-like

Loop-through connection between the associated poles of a plurality of chain-like juxtaposed bus plugs 10 to accomplish.

Referring again to Figure 3, the user, i. the customer of the connector manufacturer, even choose which poles or traces 26 of the circuit board 20 are to be looped through with a contact bridge insert 40 and which are not. The user may, at his discretion, for each individual track 26 or each

single finger 24 and each individual circuit board 20 decide whether the passage opening 36 in the

milled corresponding finger 24 and the finger 24 is thinned accordingly before the traces 26 on the printed circuit board 20 are applied to the contact bridge insert 40 selectively, so there and where it is desired to use, and thus produce the looping connection shown in Fig. 9 between the juxtaposed bus plugs 10. As can also be seen in FIG. 3, the two right-hand fingers 24 are not provided with corresponding contact bridge inserts 40

provided and thus not looped through. Overall, the invention has the advantage for the user that this

only by a change in the circuit board design can selectively decide on which interconnects 26th

Looping connections are provided and to which not. In summary, therefore, the connector assembly using the additional contact bridge inserts 40 can be upgraded, signals or voltage without the participation of

Loop through conductor tracks 26 or pass through. For this purpose, a contact bridge insert 40, in particular as an SMD component, is soldered onto the printed circuit board 20. Of the

Contact bridge insert 40 is designed so that the fully assembled bus connector 10 can be used unchanged. There are no variants of the connector housing 12 or the contact elements 28, 30 required.

The contact bridge insert 40 rests with a side 42b on the printed circuit board 20 and ensures on the one hand via the soldering the electrical connection to the associated conductor 26. On the other hand, it forms the contact surface 42a for the corresponding contact of the first contact spring 32. At the same time emerges bent by 180 ° rear Side of the contact bridge insert 40 through the Through hole 36 in the circuit board 20 through this and forms the mating contact plate 48 with the second contact surface 48 a for contact with the rear second contact spring 34. The contact bridge insert 40 is designed so that its rear second contact surface 48 b even at maximum thickness tolerance of the circuit board 20th over this by the dimension U and so the contacting of the associated second contact spring 34 with the

Contact bridge insert 40 on both sides 20a, 20b of the circuit board 20 is ensured. As a result, the contact normal force is also geometrically dependent only on the tolerance position of the contact element 40 in an advantageous manner. Moreover, the bus plug 10 does not need to be changed, i. there are no variants of

Connector 10 required, regardless of whether the

Loop-through connection to certain contact spring pairs 32, 34 is provided or not provided.

Moreover, the connector 10 has a high flexibility for the customer, since the customer by the choice of

PCB assembly can determine whether the respective contact point looping or not

looping through, i. to be parting.

It will be apparent to those skilled in the art that the above-described embodiments are to be read by way of example, and that the invention is not limited to them, but that they can be varied in many ways without departing from the scope of the claims.
