Apparatus and method for making electrical connections

The invention relates to a component that is used to produce an electrical connection between at least two electrical conductors, e.g. the conductors in a coaxial cable or shielding cable, and one electrical Component, e.g. the board of a printed circuit board, is suitable.

Numerous methods have been used to make an electrical connection between coaxial cables and the Insulation plates of printed circuits proposed. One of the devices already proposed for manufacture One such joint consists of two heat shrinkable sleeves, each one of which is made from a solder Contains existing ring. An end part of one socket is inserted into an end part of the other socket and fixed associated therewith, forming a single heat shrinkable sleeve containing two rings of solder. The device contains a single, previously inserted, round cross-section pin, both ends of which lie in one part of the socket and its middle part like this

509849/0357

is arranged to form two separate parts of the pin which are brought into a desired location can be cut through. The middle area of the pen retains the desired shape of the 5 pin when the device (by heating, whereby

the heat-shrinkable sleeves shrink and the solder melts) to be attached to the bare end of the coaxial cable ι. When the device loading \ j has been strengthened by the cable, the pin is cut, and; '10, the two parts of the pin can be used in holes that are present with [an appropriate distance in the insulating gei a printed circuit to be introduced.

; The device described above is available in four:

I (and thus by the manufacturer) is determined, and therefore that A different device is required for each insulating plate with a different hole spacing. This is a significant one

¹ 20 disadvantage, since the distances on the insulating plates of printed circuits are not standardized. Slight deviations: for example, between plates with metric dimensions and plates with English dimensions -

^; step (a metric insulation plate, for example, has a distance of 5 mm 25, while the corresponding plate

; with the English dimensions has a distance of 0.200 inch = 5.08 mm), while large differences (e.g. of 2.54 mm

¹ (0.1 inch) to 6.35 ram (0.25 inch) can occur between one consumer and another. The Her-

! 30 steller is faced with the problem, many j having to deliver different jigs each with a different j pen.

The invention relates to a device from a

The second hollow element can be pulled out when it is moved in one direction relative to the second hollow element, but can be pulled out completely when it is moved in the other direction.

Since the end of the inserted into the second hollow element: first hollow element of the device according to the invention is displaceable in the former, the distance can

printed circuits with different hole spacings

it is not necessary to make a special connection device for each hole spacing.

an electrical connection, for example between

a printed circuit and two conductors is used, the distance between the electrically conductive j

various elements can be set to the desired value; den, and the electrically conductive elements can be in | The holes in the insulating plate are inserted and attached to it according to the desired method. The ends of the ladder are exposed to a length of each ladder

Of course, i must be stripped so that there is no electrical contact between the two:

Ladders or between a ladder and someone other than j

509849/0357

j the electrically conductive element with which he elec-I is to be connected trically, is present. Then an electrical connection is made between each conductor and the

respective electrically conductive element produced. 5 In a preferred embodiment of the invention

(see below), wherein each hollow element is made of a heat-shrinkable sleeve ¹ of electrically Isoliermate-I rial and that each sleeve has a certain amount of solder

the electrical connections can be made! 10 by merely heating the device, ; causing the sleeves to shrink and the solder to melt.

If the conductors and the device are such that ■ this is possible, the electrical connection

The installation stages described above can be given; possibly reversed, i.e. the device according to • 20 of the invention is first applied to the ladders or to a

the conductor is attached (taking care that the electrically conductive elements are kept at the desired distance), whereupon the electrically conductive elements with the electrical component, for example the plate ^; 25 is connected to an electrical circuit. Furthermore, the device according to the invention can of course also be used for more than two conductors, provided that; that a hollow element and an electrically conductive element are provided for each conductor. If at- ^; 30, for example, if a third hollow element is present, the first open end of the second hollow element can optionally be held displaceably in an open end of the third hollow element. The Invention; manure thus also includes a device which also '35 a third hollow element with a first open end ',

509849/0357

and a second open end, a third electrically conductive element retained in the third hollow element is or forms a piece therewith, wherein the third electrically conductive element of the first and ' second electrically conductive element is electrically isolated.

The device according to the invention is provided with means _; see, which prevent complete withdrawal of the first hollow member from the second hollow member in at least one direction. Advantageously, the first end of the first hollow element cannot be lost in the ^; second end of the second hollow element inserted. In this case, the second electrically conductive element advantageously protrudes beyond the second end of the second hollow element. For example, the first end of the first hollow element can have a part that has a larger outer diameter than the remainder of the element and / or the second end of the second hollow element can have a part that has a smaller inner diameter than the remainder of the element. The part with a larger or smaller diameter can be obtained, for example, by providing the hollow element with a widened or a constricted part as required. As an alternative or in addition, the outside diameter or inside diameter of a part of the hollow element can be changed by applying a layer of a suitable material on the outside or inside of this part. For example, one or more rings made of thermoplastic material can be used to change the diameter in the desired manner. Examples of suitable thermoplastic materials are the meltable thermoplastic materials described in GB-PS 1,062,043. If a ring of thermoplastic material, for example, inside on the second end of the second hollow element

509849/0357

is applied, this ring not only forms a part with a reduced inner diameter, but can also do so contribute to keeping the second electrically conductive element in its position and / or in the molten state

; 5 form a dam which prevents molten solder from being drawn (if used) escapes.

Admittedly, funds like them should normally be prominent! to prevent separation of the first and second hollow elements may be present in the device according to the invention, but there may be circumstances give, among which it is more convenient to use the first and second hollow element (and the associated electrical : conductive elements) to be delivered separately, so that the

User can plug one element into the other immediately before use. The invention thus also comprises a kit of parts which consists of a first hollow element and an electrically conductive element of the type described above and a second hollow element and an electrically conductive element of the type described above. In this case, of course apparatus comprises no means for preventing the separation of the hollow members, unless in that the means' are such that they do not prevent the assembly of the device.

Although the hollow elements used in the device according to the invention can be electrically conductive ^,! at least one of the hollow members is preferably a heat shrinkable sleeve of electrical insulating material.

■ Each hollow element advantageously consists of one

Furthermore, at Verj Use of heat-shrinkable sleeves made of electrical insulation! material normally no additional insulating material ; 10 required to isolate an electrically conductive element from the other or to use the Isolate the connection established from the surrounding area. For example, the second electrically conductive j element so inserted between the overlapping parts of the j 15 two sleeves that it is from the first eleki trically conductive element and of any conductor that is inserted into the first hollow element is constantly isolated. Suitable materials for the according to

Heat shrinkable electrically insulating sleeves used in the invention are disclosed, for example, in the UK patents ; 990 235, 1 010 064 and 1 062 043. For this purpose; hear, for example, crosslinked polyethylene and crosslinked Polyvinylidene fluoride.

To improve and strengthen electrical connection between the substrates. When the device is heated is used to shrink the heat-shrinkable sleeve bring the solder melts and flows and is forced into intimate contact with the substrates by the sleeve. The solder must of course normally be placed in the socket so that it does not cover its entire cross-section fills out. It advantageously has the shape of a ring. The solder is useful from the start provided with a flux.

If a heat-shrinkable sleeve (if necessary together with a fusible material) is used to join two parts and the sleeve of any one The reason that it must have a certain diameter in its expanded state can sometimes be difficult occur that the shrinkage ratio of the socket (i.e. the ratio between its diameter in the expanded Condition and the diameter in the completely shrunk condition) is not sufficient to close the socket at Bring shrinkage in intimate contact with the parts to be connected. One encounters this difficulty often in the known devices described above, in which the sleeve with the smaller diameter must be so large that it lies against the sleeve with the larger diameter, so that the expanded Sleeves can be connected together to form a one-piece device. In the device according to the invention, however, the diameter of the first sleeve can be as small as desired (provided, of course, that means are present to prevent them from being pulled completely out of the second socket in at least one direction can), so that it is possible to establish a firm and reliable connection between the electrically conductive Element in the first hollow element and one in this

509849/0357

to manufacture hollow element introduced conductor.

At least one of the electrically conductive elements used in the device according to the invention is advantageously designed so that at least part of the end of the element protruding from the open end of the respective hollow element forms an angle to the longitudinal axis of this hollow element. The electrically conductive elements are preferably 90 ° pins, so that when using an insulating board of a printed circuit with holes which run perpendicular to the surface of the board, the hollow elements of the device according to the invention are approximately parallel to the surface of the board. Although electrically conductive elements, for example pins, with a round cross-section can be used, electrically conductive elements, for example pins, with a square cross-section have the advantage that it is somewhat easier to prevent these electrically conductive parts from rotating when the device according to FIG of the invention is installed. Each electrically conductive element is advantageously held and secured in the associated hollow element in such a way that essentially no axial displacement or rotational movement of the electrically conductive element relative to the hollow element is possible. This can be achieved, for example, with the aid of an adhesive or, in the case of a heat-shrinkable first hollow element, by shrinking the second end portion of the hollow element into firm contact with the electrically conductive element; wherein the strength of the connection formed is optionally increased by an amount of thermoplastic material. As an alternative or in addition to the first and / or second electrically conductive ■■ element fixed between the associated hollow element and a · liner, for example a ring made of solder and / or a ring of thermoplastic material, the hollow in the

509849/0357

or inserts and the electrically conductive element firmly encloses j. As the materials from which the pens are made Copper, brass, phosphor bronze and beryllium copper, for example, are suitable.

While, in the case of an electrically conductive hollow member all the methods described above are applied to the electrically conductive element within the hollow member to hold and secure, however, the electrically conductive element is preferably formed with the hollow member ■ in one piece. For example, J the electrically conductive element and the hollow; ! Element can be punched from sheet metal.

. Each electrically conductive element used according to the invention, if it does not consist of one piece with the associated hollow element, is preferably mounted in this hollow element in such a way that the axis of the part of the electrically conductive element located in the hollow element is essentially parallel to the longitudinal axis. of the hollow element. Advantageously, however, j the axis of the electrically conductive element does not coincide with j the axis of the hollow element, ie the electrically conductive element is eccentric. to the hollow element. This has the advantage that it is easier to get one; Introduce 'conductor into the hollow member, and that it is möglieh to bring the electrically conductive element in intimate contact as possible, for example, with the insulating plate of a printed circuit, so that the connection \ can be made as strong as possible to the plate. ;

For example, the hollow elements can have a cross section (for example square) such that rotation is not possible. As an alternative or _(in addition, several devices according to the invention can be attached to one or more support arms or holding arms j. For example, the first electrically conductive element of each device from a number of devices according to the invention can be j through an associated hole be guided in a first support arm,

Several devices according to the invention on one or more support arms are attached, a paddle card termination device with a variable Form a distance, and such a terminal block also falls within the scope of the invention.

The exact nature of the implementation of these measures depends of course on the The nature of the various parts of the device does not, however, present any difficulty to the person skilled in the art.

15 In addition to the advantage set out above, i.e. the possibility of a single device for insulating boards of printed circuit boards with different hole spacings to use, the device according to the invention i has the further advantage that they use in certain cases ; 20 det can be used to establish a connection between a cable and a printed circuit board, the has an impedance reasonably close to the impedance of the cable. For example, it has been found that the ; Connection of a cable that has an inner conductor and a; 25 outer conductor, to a printed circuit with J using a device according to the invention the second; electrically conductive element to some extent the j can continue the shielding performed by the outer conductor; and, if the distance between the first and the second j 30 electrically conductive element is correctly selected, j a surprisingly good impedance matching can be obtained. I So, in cases where the distance between the; electrically conductive elements not through the Lochab-I stood on the insulating plate of the printed circuit i 35 is limited to a certain value, the manufacturer

509849/0357

indicate to the user of the device what distance is needed between the electrically conductive elements must be in order to achieve the best impedance match for a given cable. The invention thus comprises a With the aid of the device according to the invention carried out method for the production of an electrical Connection between a printed circuit and a cable which has an inner conductor and an outer conductor. In particular, the invention is directed to such a method in which the distance between the i electrically conductive elements in the device according to the invention is chosen so that the impedance of the Connection is as close as possible to that of the cable.

Further advantages of the device according to the invention are that the hollow elements reduce the internal stress at the joint can eliminate and if a heat-shrinkable Insulation sleeve, which contains a certain amount of solder, is used that the sleeve itself the Insulation forms for the connection and the amount of solder may and may not be chosen by the manufacturer is left to the discretion of the craftsman installing the sleeve. Furthermore, the device can be quickly and easy to install, especially in cases where heat-shrinkable sleeves containing solder are be used.
