Abstract

The invention relates to a connector (6, 7, 18, 23) comprising at least one free-standing pin (8 to 11; 19 to 22; 24, 25), which can be connected to a conductor of a printed circuit board (28). For producing the connector, a profiled, prism or rod-shaped starting body (30) is, on one end thereof, machined by turning around an axis (A) in such a way that the at least one p in is formed from an edge or profiling of the starting body (30). The method is significantly more economical than prior art milling methods and results in the production of especially stabile pins in the case of an extruded startin g body.

Description

Huber+Suhner AG
C',H-9100 Harisau Method for Producing an Electric Connector and a Connector Produced According to this Method The invention concerns a method for producing an electrical connector according to the precharacterizing clause of Claim 1. In addition, the invention concerns a connector produced according to this method.
Such connectors are known in high-frequency engineering under the designation "print connectors." In high-frequency engineering, the electrical and mechanical quality of the connection is especially important. In order to avoid undesired attenuation and radiation effects at the connection point, high requirements must be placed on the contact quality of inner as well as outer conductors and on the shielding properties of the connector and circuit board pairing. In addition, a portable application of associated devices requires a high mechanical stability of the connection. Conventionally, a high-frequency connection is achieved at circuit boards in that the inner conductor and the outer conductor of the coaxial connector are bonded to corresponding conductors on the circuit board. Often, the contacts are soldered to the circuit board or are plugged directly into the circuit board.
The type of the bonding of the print connector to the circuit board can be configured in various manners. Often print connectors are assembled on the circuit board in the known SMD technology and soldered; this takes place primarily using the reflow soldering procedure especially suited for such purpose.
In another often used type of bonding, the connector is inserted into holes which Printed 9/20/2000 CHANGED SHEET

are specially reserved in the circuit board for them and which are in most cases throughplated, i.e., coated with metal, and on the underside of the plate often is soldered in the so-called flow-soldering bath soldering method which is especially suited for this purpose. In another method, the coaxial connectors with the inner conductor and the outer conductor are inserted, directly and gas-tight, into metallically conductive holes in the circuit board which are adapted specifically for that purpose via specially shaped, innately mildly springy grooved-pin-like feet. In still another frequently used method, the connector is embedded and soldered lying on the edge in a recess set at an edge of the circuit board, wherein not a vertical axis of the conductor is selected as in the method described previously, but rather an axis parallel to the plane of the circuit board is selected.
The production of such connectors or print connectors in the past took place in a milling process with comparably expensive production equipment. The geometric features of the connectors differ depending on the type of contact with the circuit board. The milling procedure used in the past was comparably involved and time intensive. It should be noted that such connectors are produced in high numbers.
In addition, handling is made more difficult as a result of the small dimensions of such connectors. Disclosed in GB 2 272 800 A is a print connector in which exposed pins are produced from an initial body through turning and through milling. Thus a milling machine is required in this case for producing [the connectors]. WO 97/45899 discloses a coaxial connector in which the connector pins are produced from the four corners of a four-cornered billet through turning and milling.
The invention is based on the task of creating a method of the type mentioned which makes possible a significantly more cost-effective production of connectors of the type mentioned.
Printed 9/20/2000 CHANGED SHEET

The task is achieved in a method according to the preamble of Claim 1 in that a profiled, prism or rope-shaped initial body at least at its one end is processed by turning such that from one edge or profile of the initial body, at least one pin is exposed. Essential for the method is the above-mentioned initial body from which a connector can be produced through turning more cost-effectively and more simply than previously. A connector of the type mentioned can essentially be produced solely through turning of the initial body mentioned. The processing machinery necessary for this purpose is essentially less expensive than the milling equipment necessary in the past. The above-mentioned initial body can in particular be produced through drawing, extrusion, or molding. A drawn initial body has proven to be especially advantageous, with a significant increase in strength of the exposed pin, the so-called print foot, being possible. The contacts are accordingly much more stable. Deformations and warping of these print feet can be avoided with this production and handling process.
A further technologically interesting possibility is provided through an additional, for example, plastic deformation or a cutting process c>n the pins or print feet which can then be inserted directly and without soldering into a corresponding circuit board and thus provide an electrical and mechanically reliable as well as gas-tight contact. Additional advantages of the method according to the invention are the higher production precision and the higher degree of reproducibility of the relevant process values.
Additional advantageous features are contained in the dependent patent claims, the following description, and the drawing.
Printed 9/20/2000 CHANGED SHEET

Exemplary embodiments of the invention are explained in greater detail below with the aid of the drawings.
Figure 1 shows a three-dimensional view of an initial body;
Figure 2 shows a cross section through the initial body according to Figure 1;
Figure 3 shows a three-dimensional view of a connector according to the invention for vertical mounting on a circuit board, with this connector being especially suited for reflow soldering;
Figures 4 and 5 show variants of the connector according to the invention which are suitable for vertical mounting on a circuit board and are especially suited to flow-soldering bath soldering; and Figure 6 shows a connector according to the invention which is placed horizontally on a circuit board which is shown only in part here.
Figure 1 shows an initial body 30 which preferably is produced of metal and which has four ribs 2-5 which protrude radially and run parallel to a longitudinal axis A. Initial body 30 is preferably composed of material which is drawn in the direction of axis A. Initial body 30 is thus formed in a profiled manner.
However, it can also be prism- shaped or otherwise shaped such as rope-shaped. Besides drawing, it can also be produced through extrusion or molding. Figure 2 shows a cross section through initial material 30. As shown by Figure 2, initial material 30 comprises a basic body 1 and four uniformly protruding ribs 2, 3, 4, and 5.
Initial body 30 is processed through turning around axis A. In this manner, as suggested in Figure 2, the cylindrical zone 1 is partially removed by turning with the diameter d. Ribs 2 through 5 Printed 9/20/2000 CHANGED SHEET

in this process are exposed and form print feet 19 through 22 in the connector shown in Figure 3. The through hole 18a shown in Figure 3 and the jacket surface 18b are preferably also produced through turning around axis A. Thus connector 18 essentially can be produced solely through turning of initial body 30.
Connector 18 preferably is a coaxial connector outer conductor in SMD
technology. It is arranged vertically on a circuit board and is bonded through reflow soldering. Through the configuration of the cross section of initial body 30, various forms of print feet 19 through 22 can be produced. Initial body 30 can fundamentally also be prism-shaped, for example quadratic in cross section.
The corners of the initial body then form the correspondingly shaped print feet.
The forming of the print feet can also be changed through changing the diameter d as well as through the depth of the hollowing out by turning.
Figure 4 shows a connector 6 which has four shoulders 12 through 15 as well as continuously tapered inlets 16 and 17. Shoulders 12 through 15 and inlets 16 and 17 are likewise produced through turning. Connector 6 is provided for vertical mounting on a circuit board. For bonding, flow-soldering bath soldering, which is known as such, is especially suitable for this.
Figure 5 shows a further variant of a connector 7 which has four print feet 8 through 11.
Figure 6 shows a connector 23 which is inserted horizontally in a rectangular groove 27 of a circuit board 28. Connector 23 is a coaxial connector housing.
It Printed 9/20/2000 CHANGED SHEET
~.~ .-m"~..,~",..".~., ....-.~.~",~"~_.. .

has only two print feet 24 and 25. These print feet 24 and 25 form outer conductor contacts and are produced solely through turning. The initial body used for connector 23 has accordingly only two ribs, by way of example in Figure 2, ribs 2 and 3. In addition, connector 23 has two parallel outer surfaces 26 which by way of example can be produced through milling. An embodiment is also conceivable in which the connector has only one foot for electrical contact. Finally, embodiments with more than four feet or pins are also conceivable.
