Description

The present invention relates to a connection device for fastening at least one line on a printed circuit board and for producing an electrically conductive connection between a conductor of the line and corresponding terminals of the printed circuit board, wherein the connecting device has a housing. The invention further relates to a method for fixing the line on the circuit board and for producing said electrically conductive connection.

There are already known connection devices, which are also referred to as connectors. These connectors have a housing in which a spring contact for the production of an insulation displacement connection with the wires of a ribbon cable is arranged.

In connection with the use of single-core cables or multicore cables such as raster line cables, there is also the desire to fix them mechanically by means of a connecting device securely on the circuit board and to be able to connect electrically conductively to corresponding terminals.

The object of the present invention is therefore to provide a simply constructed and inexpensive to produce connecting device which produces a mechanically and electrically secure connection of a single-core line or a ridge line with a circuit board or with corresponding terminals of a printed circuit board. The object is also to provide a simple method for the preparation of such a compound.

The above object is achieved by a connecting device in which at least one contact element is arranged in the housing, wherein the contact element respectively first means for fixing the line, second means for forming an electrically conductive connection with the conductor (strand) and third means for training an electrically conductive connection with at least one corresponding terminal of the circuit board. In this case, the line may be formed as a single core line or raster line.

The connecting device according to the invention is suitable for attaching one or more lines to a printed circuit board. By using the preferably integrally formed contact element, the structure of the connecting device is simple and inexpensive. A contact element is preferably provided for the connection of exactly one conductor with one or more terminals of the printed circuit board.

The line can be attached to the contact element by means of a crimping, welding or soldering connection.

In a development of the invention, the third means of the contact element are designed as at least one contact pin, preferably a multiplicity of contact pins. Each contact pin has a press-in zone or a soldering tag. By means of the contact pin, the line can be connected to a terminal of the circuit board. Accordingly, a plurality of contact pins serve to connect the contact element with a plurality of terminals of the circuit board. Here, the formation of an electrically conductive connection of a conductor of the line with two or more terminals of the circuit board is advantageous because high currents, ie currents up to 18 A, can be transmitted by splitting the streams in several places. Such a connection device is also suitable for use at high temperatures, ie up to 125 ° C.

The use of contact elements with press-in zone, preferably a needle-shaped press-fit zone, enables better maintenance of the connection between the line and the printed circuit board, since the press-in zone can be pressed in and out of corresponding openings in the connections of the printed circuit board several times. The connection between the press-fit zone of the contact pin and the corresponding opening of the printed circuit board is also referred to as press-fit connection or press-fit connection.

With the connecting device according to the invention, a plurality of variants of the connecting device can be realized in a simple manner. On the one hand, in the case of a contact element, the design of the third means for forming an electrically conductive connection and, on the other hand, the number of contact elements arranged in a connection device and their arrangement (one behind the other and / or side by side) can be adapted to the corresponding requirements of the connection task. Therefore, a plurality of contact elements, preferably parallel to one another, is preferably arranged in the housing.

In one embodiment of the invention it is provided that the contact element is connected by means of a latching connection with the housing or a housing part. For this purpose, either the housing or the housing part or the contact element on a tab or a plurality of protruding tabs, which engage behind a corresponding projection or edge of the other part, which or which is optionally arranged on the edge of a window.

It is further preferred if the housing has on its underside at least one positioning finger (positioning pin, centering pin), which allows a correct positioning of the housing with respect to the printed circuit board.

In a first preferred embodiment of the device according to the invention, a contact element is used, which is designed substantially tab-shaped in its central portion. Due to their simple and flat structure, the contact elements can easily be rolled up onto a roll during their production, so that later processing to the connecting device according to the invention is facilitated. The contact elements are rolled up during their manufacturing process on a roll with paper liner for further processing in electroplating and assembly.

Preferably, in an upper portion located above the tab, the first and second means are realized as a crimping, welding or soldering connection. Particularly preferably, the first means and the second means in the upper portion are each formed as tabs for a crimped connection. The connection of the line or lines is therefore in this embodiment in a direction perpendicular to the circuit board surface. On its underside, the tab preferably has a plurality of solder tails or press-fit contact pins as third means, which can be connected to corresponding terminals of the circuit board. A contact element or a plurality of contact elements can be arranged in a housing and are defined in this example by a snap mechanism.

In a second preferred embodiment of a connecting device according to the invention, the housing is in two parts, preferably composed of a lower part and a lid.

Preferably, the contact element is formed substantially U-shaped, in particular for use in a connecting device in which the housing is designed in two parts.

The two-part housing has the advantage that the housing cover protects the contacts between the lines and the contact elements from damage. Furthermore, the housing cover serves as an insertion aid for the lines in the housing. In addition, the lid serves as additional protection against tearing of the line due to the realized through the lid strain relief. In the second embodiment, the cover is used in particular for pressing the lines into a defined depth into the insulation displacement terminals formed by the contact elements.

It is further preferred if the first means and the second means are formed in the same portion of the contact element as a preferably U-shaped cutting edge or edge, wherein the cutting edge surrounds a slot in a wall of the contact element. The U-shaped cutting edge serves to form a per se known insulation displacement connection, which is characterized by a particularly high level of safety of the electrical and mechanical connection. Furthermore, an insulation displacement connection is simple, quick and inexpensive to manufacture, as it is a soldering, screwing and stripping-free technique. In addition, the insulation displacement connection technology allows the connection of the line or lines in a direction parallel to the circuit board surface, so that the connection between the line and the circuit board is formed overall very flat.

In the above-described second embodiment of a connecting device according to the invention, the two opposite legs of the U-shape of the contact element in respective slot-shaped recesses each form a cutting zone, in which the respective line to which the contact element is to be connected, by means of the lid of the housing is pressed to form the insulation displacement connection. The realization of two mutually opposite insulation displacement zones in a contact element is advantageous, as a result, the transmitted currents can be increased. Also in mechanical terms, the insulation displacement connection is advantageous because it increases the necessary forces that lead to tearing of the line.

On the underside of the contact element are preferably a contact pin or a plurality of contact pins, preferably two contact pins, each formed with a press-in zone, which serve for connection to corresponding terminals of the circuit board. Alternatively or additionally, a corresponding number of contact pins can be provided with solder tails.

In the region of a base of the U-shape, the contact element further comprises a protruding tab, which snaps into a corresponding recess during insertion of the contact element into the housing lower part. As a result, the respective contact element is fastened in the housing.

Another advantage of the second embodiment of the present invention is that the contact elements in the housing, preferably in the lower housing part, can be pre-assembled. This simplifies the manufacture of the connecting device. Further, the housing may be connected to the preassembled contact element (s) with the circuit board before the line (s) are attached to the contact element (s). This saves costs since the leads do not have the higher temperatures, e.g. when soldering, have to withstand. The material of the lines must therefore not be selected particularly temperature-resistant.

several ways of arranging the lines or the contact elements in the housing analogous to embodiment according to Fig. 10 ,

Based on FIGS. 1 to 8 a first embodiment of a connecting device according to the invention is shown.

The connecting device has a housing 11, in which four contact elements 13 are arranged parallel to each other. Alternative connecting devices may also have only one contact element, two, three or more than four parallel and / or juxtaposed contact elements. In the presentation of the Fig. 1 is the connecting element according to the invention connected to a printed circuit board 15.

Each contact element 13 can be connected to a single-core line 17. This is in Fig. 1 not shown. Instead, shows Fig. 3 the connection of a single-core line 17 with a second variant of a contact element 13 'separately.

In the (not shown) connection of a grid line with the connecting device according to the invention each conductor is connected to a contact element 13, 13 '.

This in Fig. 3 shown, from a metallic material, preferably made of a copper alloy, integrally manufactured contact element 13 'has as a central portion on a tab 21 which connects an upper portion 23 and a lower portion 24 with contact pins 25 electrically conductive. The upper portion 23 includes first means for defining the conduit in the first portion 27 and second means for forming an electrically conductive connection with the conductor 16 in the second portion 28 and connects via a neck at the top of the tab 21.

In the first section 27 two opposite tabs 31 are provided, between which the line 17 can be inserted. To fix (fasten) the line 17 to the contact element 13 ', the tabs 31 are bent inwards and form a crimp connection. The crimp connection has the advantage that it represents a homogeneous, difficult to detach connection, which ensures a high level of mechanical safety.

The exposed conductor 16 or optionally exposed wires of the line 17 are electrically conductively connected in the second section 28 to the contact element 13 '. Also on the second section two opposing tabs 33 are formed, which receive the stripped conductor 16 or exposed strands between them and are bent or crimped inwardly to form a crimp connection. With regard to the electrical contact between conductor 16 and contact element 13 'formed by the crimp connection, the crimped connection, in addition to the above-mentioned mechanical safety, also ensures a high degree of electrical safety. The contact pins 25 of in Fig. 3 and 4 illustrated variant of a contact element 13 'have a needle-shaped press-in zone 25 for producing a press-fit connection with the circuit board 15.

Fig. 5 shows a further possibility of a usable together with the first embodiment of the connecting device according to the invention contact element 13. This has in the lower portion 24 instead of the press-fit contacts contact pins 29 each having a Lötfahne by means of a solder connection with corresponding terminals, for example recesses 35 (see Fig. 9 ), the circuit board 15 can be connected.

To establish a connection between a line 17 or more lines by means of the basis of Fig. 1 to 8 described connection device according to the invention, the first stripped at its end line 17 is connected by means of two crimp connections in the first portion 27 and the second portion 28 with the contact element 13 or 13 '. For the production of each crimped connection, a crimping tool, for example a crimping tool, is used in each case, which must be matched precisely with respect to the shape and the pressing force to the respective crimped connection. Subsequently, a contact element 13, 13 'or more of these contact elements 13, 13' together or successively inserted into the housing 11 and locked there. For this purpose, the housing 11 tabs 20 which project into the channel of the housing 11, in which the contact elements 13, 13 'are introduced. After the contact element 13, 13 'is fully inserted into the housing 11, the lower end of the tab 20 at the upper edge 21 a of the tab 21 of the contact element 13, 13' in such a way that it the movement of the contact element 13, 13 'to prevented from the top of the housing. The upper edge 21 a of the tab 21 of the contact element 13, 13 'is latched behind the tab 20 of the housing 11. This is in Fig. 8 shown.

Subsequently, the thus assembled connection device according to the first embodiment is connected to the circuit board 15. In order to be able to position the connecting device correctly on the printed circuit board 15, the housing 11 of the connecting device has on its underside two obliquely opposite positioning fingers 18. These are inserted into corresponding openings 19 of the circuit board 15. At the same time, the press-in zones of the contact pins 25 of the contact elements 13 'and the solder tails of the contact pins 39 of the contact elements 13 are electrically connected to the terminals of the printed circuit board 15 (openings 35). This is done in the case of the press-in connection by pressing the contact pins 25 into the openings 35. In the alternative of the solder joint, the solder tails of the contact pins 39 are soldered into the openings 35.

A second, in the 10 to 20 Illustrated embodiment of a connecting device according to the invention is composed of a lower housing part 41, a housing cover 42 and one or preferably a plurality of contact elements 43rd

In the Fig. 12 separately shown contact elements 43 are made of a metallic material, preferably a copper alloy, are substantially U-shaped and have a first leg 45, a second leg 46 and an intermediate base portion 47. On the underside of the base portion 47 two contact pins 49 are each arranged with a needle-shaped press-in zone. Alternatively, the contact pins 49 may be formed as Lötfahnen (analogous to the contact pins 39 with the Lötfahnen the first embodiment).

By means disposed in the base portion 47 of the contact element 43 protruding tab 51, the contact element 43 is latched in the lower part 41 of the housing. For this purpose, the tab 51 snaps into a corresponding recess of the lower housing part 41 such that the tab 51 engages behind a corresponding projection 52 of the lower housing part 41 (see Fig. 14 ).

In the basis of the FIGS. 10 to 20 illustrated variant of the second embodiment, eight contact elements 43 are arranged in the lower housing part 41, wherein two contact elements 43 are adjacent to each other.

Each contact element 43 has at its first leg 45 and its second leg 46 a U-shaped cutting edge (edge) 53 which forms a slot 54 in the respective leg 45, 46. In the slot 54, the line 17 is fixed by means of the so-called insulation displacement technology in the contact element 43 and made an electrically conductive connection between the conductor of the line 17 and the contact element 43. The slot 54 has a smaller width than the diameter of the arranged in the line 17 conductor 16.

To produce the connecting device according to the invention according to the second embodiment and a connection between a line 17 and a printed circuit board 15, the contact elements 43 are first inserted into the lower part 41 of the housing and latched there by the respective tab 51 and behind a projection 52 in the housing lower part 41 ( please refer Fig. 14 ).

Subsequently, as in 15 to 17 shown, in each, by each two juxtaposed contact elements 43 and a corresponding slot-shaped recess 57 in the side wall of the housing base 41 formed channel 55 (see. Fig. 19 ) inserted a line 17, in such a way that it abuts with its front end to the opposite side wall of the housing base 41.

Subsequently, the housing cover 42 is placed on the housing lower part 41 (see 15 to 17 ) and, as in Fig. 17 shown, pre-locked in the housing lower part 41. The pre-locking of the housing cover 42 on the lower housing part 41 by means of undercut latching fingers 59, which engage behind corresponding first projections (locking lugs) 61 in the lower housing part 41. In this position, the four lines 17 are on the upper end of the slots 54 formed by the cutting edge 53. This intermediate state of the connecting device according to the invention according to the second embodiment in the production is also referred to as the first state.

In the next step, the lid 42 is pressed down in the direction of the lower housing part 41. As a result, the cutting edges 53 cut the outer insulation of the respective line 17. Further, the blades 53 make electrical contact with the inner strands 16 and press them. In accordance with the insulation displacement technology, both a mechanical fastening of the line 17 in the two-part housing 41, 42 and an electrically conductive connection of the conductor 16 arranged in the line 17 with the respective contact element 43 are thereby formed. This second state of the second embodiment of a connecting device according to the invention with the fixed and electrically connected line 17 is in 10, 11 . 18 and 19 shown.

Fig. 18 It can be seen that engage in the second state, the latching fingers 59 of the housing cover 42 behind corresponding second, on the housing lower part 41 projecting locking lugs (projections) 62. The second latching noses 62 are further away from the housing cover 42 than the first latching noses 61.

A particularly noteworthy advantage of the second embodiment of the connecting device according to the invention is that the not yet connected to lines connecting device with lower housing part 41 and arranged in the lower housing part 41 contact elements 43 (see Fig. 13 ) can already be connected to the printed circuit board 15 via a press-fit, weld or solder joint analogous to the method which has already been described above with respect to the first embodiment. In this case, the lines 17 are inserted into the connecting device only after the connection between the connecting device and the printed circuit board has been established and fixed in the lower housing part 41 by means of the housing cover 42 or electrically connected to the contact elements 43. This allows the use of manufacturing techniques such as soldering, which require the use of higher temperatures, without the lines are also exposed to these high temperatures. The cables used therefore do not have to be so temperature-stable and can therefore be manufactured kostengünster.

Furthermore, it should be noted that the leaders in the basis of the 10 to 20 illustrated second embodiment of the connecting device according to the invention parallel to the surface of the circuit board 15 extend. In contrast, the conductors in the connection with the in the Fig. 1 to 8 illustrated first embodiment arranged such that its longitudinal axis is substantially perpendicular to the circuit board surface.

In Fig. 20 Several variants are shown how the inventive connecting device designed according to the second embodiment and single-core lines can be arranged with respect to these. The in the FIGS. 20 c) and d) shown arrangements are so-called end plug connector. In these, the lines 17 are struck with their front end to the opposite side wall of the housing base 41. In the Fig. 20 a) and b) In contrast, so-called possibilities Through-connector, which can be arranged in any portion of the lines 17. Here, the lines penetrate 17 both opposite side walls of the housing base 41st

The in the FIGS. 20 b) and d) Variants shown differ from the examples shown in Fig. 20 a) and c) , In the number of their juxtaposed contact elements 43. Of course, it is also possible to arrange three or more contact elements 43 side by side.
