THROAT THRESHOLD MATRIX

The invention relates to switching means, in particular one electrical woven two-dimensional matrix used in the electronic Technology for commutating electrical signals is used.

An electrical woven matrix is known which is based on the basis of an interweaving of insulation threads as well x- and j- selection lines are carried out, which are combined into groups each of which consists of at least two parallel lines belonging to a selection direction.

Each group of lines is arranged in such a way that they form a thread formed by an interweaving of insulation threads Crossing the isolation field in an alternating direction by alternately entering the isolation field, sometimes out of it exit. At the geometric crossing points are the groups belonging to the different selection directions

609808/0895

Lines arranged on different sides of the mentioned insulation field, and only at previously encrypted locations, where there is an electrical contact between the corresponding Groups of the x and y selection lines are required, contact groups are in the form of an interlacing of on an area of the isolation field led out x- and y -selection lines of the corresponding groups formed Lattice running.

The known electrical woven matrix is for commutation of and arranged on the periphery of the matrix The contact connections connected to the groups of the x and y selection lines input and output signals (see for example Federal Patent No. 1959956) provided.

In a number of cases, however, there is a need for the circuit elements not only on the perimeter of the Matrix, but also to be arranged in its area and the connecting wires of the former to the contact terminals of the Coupling the matrix in a corresponding manner.

The known electric woven matrix is absent the contact connections arranged on the surface, which is their main disadvantage.

Another disadvantage is the great amount of work involved in the manual operation of separating the lines from the insulation threads accompanying them in the same direction, which is only possible after the matrix has been produced on a weaving machine

609808/0895

follows, as well as the complexity of the next step -

the removal of these insulation threads and the formation of Connect contacts from the lines.

At present the question of an optional elimination or reduction of in modern electronic circuits is on occurring on the basis of woven matrices of the known type Inductions acute

In the known electrical woven matrix, there is no way of eliminating the inducements of the lines one group is provided by the lines of the other group, which is also seen as a disadvantage of such a matrix which limits their widespread use in modern electronic circuits.

Another shortcoming of the known matrix is that technological difficulties arise in its production, those with different lines made of metal and with different mechanical Jurameter for braiding Isolation threads required one-cell sizes and modes of operation of the looms

different
Such divisions and parameters are on one

Loom incompatible, therefore the real operating status and the setting parameters of the loom become during manufacture matrices known in this way are selected as the center anything but optimal.

With the known matrix there is no possibility

6098 08/0895

that the connecting wires of the circuit elements with the contact groups the matrix in those cases where the contact and connection of the arranged on the surface Circuit elements come about through a solder wave.

IUe contacting with the help of the solder wave comes about out of the question because the known matrix has an implementation the connection wires of the circuit elements are not provided due to the isolation field of the matrix

The purpose of the invention is to overcome the disadvantages mentioned

The invention in question is based on the object to create a woven electrical matrix, the technical implementation of which allows the circuit elements not connect only to the perimeter of the matrix, but also to the surface of the latter, and a lead-through of the connecting wires the circuit elements through the isolation field of the matrix, significantly simplifying their manufacture and To enable a reduction in the proportion of manual operations.

This object is achieved in that the electrical woven matrix is based on an interweaving of insulating threads as well as x- and y-selection lines are executed, which are combined into groups, each of which consists of at least there are two parallel lines belonging to a selection direction, each group of lines being arranged in such a way that

609808/0896

that they the insulation field formed by the insulation threads crossed in alternating direction by entering the field alternately once from it, and to the geometric crossing points the groups of to different Lines belonging to the selection directions are arranged on different sides of the insulation field, while on the encrypted locations where electrical contact is required between the corresponding groups of the x and y selection lines is, contact groups in the form of an interlacing of led out onto a surface of the insulation field σ and y selection lines of the respective groups formed grid are executed, and a part of the groups of lines of a selection direction according to the insulation field the invention crossed in alternating directions in such a way that after exiting the field in this again in Bypassing several groups of the lines of the second selection direction and forming one above the one interlacing of insulation threads of the x and y directions of selection and said insulation field representing said plurality of groups of lines of the second selection direction Layer of parallel lines enters

Appropriately, in the zone of the contact group, there is at least one line in the form of a line protruding beyond the contact group Loop executed.

609808 / 089S

It is quite useful to be parallel to that of a shield require groups of lines, additional isolated ones Arranged lines that follow the interweaving pattern of the groups of lines to be separated.

It is advantageous to use insulation threads impregnated by an electrically conductive agent as lines.

It also proved useful during the general Interweaving of insulation threads and cables through thread through the middle of the contact group insulation threads, which do not go into the entire interweaving pattern, and then pulling these threads out, thereby creating the training of windows for the passage of the electrical connection wires of the circuit elements is made possible.

The electric woven matrix created in this way: gives the opportunity not only to the circuit elements the circumference of the matrix, but also to be arranged on its surface, the contact connections being carried out on the surface which make it possible to connect to them circuit elements that have both a planar and an end-face arrangement of the connecting wires.

Besides, the manufacturing technology for the matrix is improved because of the manual operations for the selection and cutting out an insulation thread parallel to the lines have been fixed.

It is a shielding of the required groups of the

6G98Ö8 / 0895

lines, by introducing the matrix structure of additional Achieved isolated lines and also Lei lines and insulation threads with the same mechanical parameters been used, which makes it possible to approximate the modes of operation of the looms to the optimal.

A specific embodiment of an electrical woven matrix according to the invention will now be considered.

1 shows a section of the matrix in the area of

609808/0895

Arrangement of a contact group 1.

The electric woven matrix is as from the drawing can be seen on the basis of an interweaving of insulating threads 2 and to x and y selection directions of the Matrix belonging lines 2 executed. The lines 3 3 of the selection directions are combined into groups 4 and 5, each of which consists of at least two parallel lines 3 belonging to a selection direction, where the number the lines 3 in a group 4 or 5 can be any.

At the previously encrypted points in the matrix, where there is electrical contact between the corresponding groups 4 and 5 <all x and y select lines 3 are required the contact groups 1 in the form of an interweaving lead out onto a surface of the insulation field x and y selection lines 3 of the respective groups 4 and 5 formed grids executed.

Located at the other geometric crossing points the lines 3 of the different groups 4 and 5 are located different sides of the insulation field formed by the interweaving of the insulation threads 2.

ü in part 4 of the lines 3 of a y-selection direction occurs, after stepping out of the field formed by the interweaving of the insulation threads, again in the sorrow, wherein he several groups 5 of the lines 3 of the second x-selection direction bypasses.

609808/0895

atf

-sin *? d such arrangement of the y-selection lines 3 with respect to of the insulation field 6 is indicated in FIG.

In such a way, one is above one by interlacing the insulating threads 2 (FIG. 1) with the groups 5 of the lines 3 of the second x-selection direction formed section 7 of the insulation field 6 located layer of parallel lines 3 (Fig.3) formed.

This section 7 (Fig. 3) can be used in the following, if necessary, with the formation of a window 8 (Fig. 4) for Implementation of a connector or a circuit element can be cut out.

In addition, the in the interweaving with the lines of the other selection direction not incoming layer of lines 3 in two parts with the formation of the lines 3 of two rows of contact connections, as shown in Figure 5, cut

will.

Fig. 6 shows part of a stiffening member fixed and two rows of contact terminals formed from lines 3 cut into two parts Matrix.

Connection wires 10 of a circuit element 11 can be connected mechanically to such connections Couple the end of the soldering with a soldering metal 12.

609808/0895

The circuit element 11 is on the insulation field 6 of the matrix in analogy to the attachment of the circuit elements arranged on a printing plate, i.e. the element 11 is glued to the field 6.

The generation of such a layer of lines 3 CJfig.3.) Is no less advantageous in terms of training of connections of the matrix on the perimeter.

In the vicinity of the edge of the matrix, a layer of lines 3 intertwined with the insulation field 6 is created right at the band e.

Section 7 is cut out, and one formed by interweaving insulation threads, threads and lines 3 Volume 1 $ (Fig.7) remains as a provisional technological one Stabilizer, which can also be cut off later.

This is a labor-intensive operation of freeing the lines 3 from the accompanying isolation fids has been fixed, as the latter have a separate, at HOtwfiddigkeit Form an insulating layer to be removed by cutting out

Fig.8 shows one in the form of a grid from the interwoven Lines 3 executed contact group 1.

In the zone of this contact group 1 there is at least one of the lines 3 forming the group 1 in the form of a loop 14 executed.

In the specific example in question, there are two lines not drawn into the interweaving, but they protrude beyond the contact group 1 (51g ·) »whereby they loops 14 · form.

These loops 14 can subsequently be used as connections of the matrix for connection to the connecting wires of the circuit elements be used.

To reduce inductions on the neighboring power lines and to shield the lines 3 themselves are additional isolated lines 15 in the matrix (Fig. 10) introduced parallel to lines 3 (or groups of the lines 3) which require shielding .

These additional lines 13 are parallel to the Lines 3 instead of the insulation threads 2 are allowed to pass through and foil the interweaving pattern of the aforementioned to be shielded Lines 3

The additional lines 13 are grounded, and on this In this way, there is a shielding of both the lines 3 generating the inductions and that of the lines 3 which are exposed to strong inducements exposed lines 3.

To secure optimum modes of operation at an electrical ^v woven matrix on weaving machines are executed Leitungein 3 and 15 from well-known electrically conductive filaments electrically conductive fillers are introduced into the composition.

609808/0695

Such electrically conductive threads are mechanical according to their Parameters close to the parameters of the insulation threads 2, which also ensures the optimal production of the woven

Matrix guaranteed.

For training at certain encrypted points

'for general construction or circuit technology reasons

required windows is it

necessary to provide additional insulation threads 16 (Fig.11) when braiding the matrix on a loom, which both in the weft and in the warp.

These insulation threads 16 participate in the whole Interweaving of the insulation threads 2 and the cables *> not, but they are intertwined with the lines J only in the zone of contact group 1, as shown in FIG. 11 shown is a.

The following are the additional threads mentioned pulled out of the entanglement, and on the one through it occupied area, windows 17 (FIG. 12) are formed, which allow contact connections to pass through them Circuit elements are provided.

Fig. 'I ^ shows a window having no windows Circuit element 18 arranged in a matrix. In this case, the connecting wires I9 of the circuit element 18 are connected the lines 3 coupled on the side of the matrix of the circuit element; Ίο sexbst lies.

"My forehand: · ;:" a

ν von Fenstem17 (Fig. 14), through which the connecting wires 19 of the circuit element 18 are passed,

the connecting wires 19 to the lines 3 are on coupled to the opposite side of the matrix.

All circuit elements are therefore arranged on one side of the matrix and all contact connections on the led out other side, which gives the possibility of soldering connections to a advanced method - a solder wave.

The present woven electrical matrix can be based on the known looms using known devices to maintain all necessary changes in Interweaving pattern of the lines 3 and the threads 2 (Fig.1) be made. It should be emphasized that the one shown in FIG Variant, the interweaving pattern is not the only possible one is.

The interlacing can be done according to the requirements of the position d. _{he zli} different selection directions χ and y of the matrix belonging lines 3 are realized on different sides of the insulation field in their geometric crossing points sufficient pattern.

Performing operations such as creating the contact groups 1, making a layer of wires (Fig. 3) over a section 7 of the insulation field 6, execution of loops 14 (Fig. 8) in the previously programmed

609808/0895

Contact groups 1, introduction of additional insulated lines 15 (Fig. 10) and braiding of the additional insulation threads 16 are in the zone of the required contact group 1, takes place in known and widely used in weaving Procedures applicable to the application of this or that operation for a pre-programmed time and at a specific, predetermined point of the interweaving of the matrix.

The present electrical woven matrix can be used in any modern electronic equipment, especially in Switchgear for electrical signals, are widely used.

A major advantage that allows the matrix to be used in numerous circuits is the fact that the connection of circuit elements not only on the perimeter, but can also be done on the surface of the matrix.

This circumstance ^ has a great importance in the electronic Technology, because it gives the possibility of an exchange of multilayer printing plates through a cheaper and much more reliable electrical woven matrix, without the The construction of units will change significantly, for example instead of a multilayer printing plate a matrix according to the invention fastened to a support body is accommodated on the same surface.

609808/0895

This advantage is achieved in that at least one in the zone of electrical contact group 1 (ed. 8) The line lying on the matrix is not drawn into the group, but the contact group 1 in the form of a loop 14 (Fig. 9) surmounts a certain size. This loop 14 represents a contact connection, and to them the contact

connections of both a planar and an end face Arrangement of the connections having circuit elements are coupled.

The same advantage is obtained, also through the picture over the Area of the matrix of a layer of freely hanging, emerging from the interweaving of the insulating layer 6 of the matrix and in these lines entering at a certain distance *> (Fig. 3) reached.

After performing the operation of cutting the above free hanging wires j5, one gets Contact connections of the matrix (Fig.5) »to which the connecting wires of the circuit elements can be coupled.

The difference between these two types of connection is that if the loops 14 (Fig.8) in the zones the contact groups (1) allow a connection of the circuit elements only to the contact groups 1, so there is a case the free-hanging lines provide a way of connecting the circuit elements to the matrix on a none Contact groups. 1 section.

In addition, the labor intensity of the manufacture such a matrix by eliminating the manual work process the selection of the lines from a common row of the insulation threads lying according to the circumference of the matrix and Significantly reduced lines.

This is achieved by changing the structure of the tissue in the edge zones, where the contact connections of the matrix are to be produced. In the zones mentioned, the lines J of the warp or the weft form a second layer over "the layer of an insulating fabric made from the insulating threads 2 of the warp and the weft", i.e. the lines of any selection direction emerge from the insulation fabric and only enter it in a specific one Distance equal to the length of the presumed contact connections.

The said section located under the lines of the insulating fabric can either be cut out or left as an insulating pad.

The benefit given is very substantial because it is the manual work when selecting and cutting out each insulation thread 2 parallel to the lines 5 eliminated.

By introducing into the structure of the matrix of the insulated lines 15 running parallel to the lines 3 (ELg.10) is a shield of the former against inductions

609808/0895

ensures what the application area of such matrices considerably expanded in modern switchgear.

In addition to reducing the labor involved in making the present electrical woven matrix, are the methods of making the matrix on the looms approximated to the optimal

This advantage is achieved by exchanging the lines 3 made of metal for conductive threads, which are obtained by introducing electrically conductive fillers or coatings into their insulating base and have mechanical parameters that are close to the parameters of the insulation threads.

And, finally, is an important advantage of the matrix -Krmöglichung carrying out the connection wires of the sound processing elements through the windows 17 (Fig, ^/ I2) of the matrix, the Anlötung of the connecting wires of the circuit elements to the terminals of the matrix in an advanced industrial process - with a Solder wave - guaranteed.
