Definitions

• the invention relates to a connector for printed circuit boards according to the preamble of claim 1.
• the connector for printed circuit boards comprises a number of contact elements, wherein the contact elements each have two connection sides, wherein one terminal side is formed as insulation displacement contact for connecting wires and the other terminal side as a fork contact for contacting pads on a printed circuit board, and a Plastic housing into which the insulation displacement contacts of the contact elements can be inserted, wherein the insulation displacement contact and the fork contact are arranged rotated and at least one lower edge of the insulation displacement contact is supported on the plastic housing, so that the contact elements in occurring Anschalt Wunsch Wunsch Wunsch Wunsch, on the insulation displacement contacts are held captive in the plastic housing, wherein the plastic housing comprises at least one chamber-shaped area and the fork contacts are completely received in the longitudinal direction of the plastic housing, wherein in the chamber-shaped B Ranges are arranged on the inner sides, which define guides for the fork contacts, wherein the contact areas of the fork contacts protrude over the ribs and the ribs are bevelled in the front region.
• the packing density is largely
• the invention is now based on the technical problem of providing a connector for printed circuit boards, which has alternative wire connection contacts to insulation displacement contacts, without the To reduce packing density or connection density of the fork contacts.
• the connector for printed circuit boards comprises a number of contact elements, wherein the contact elements each have two connection sides, wherein one terminal side is formed as a fork contact for contacting pads on a printed circuit board, and a plastic housing in which the contact elements are arranged, wherein the wire connection contacts of can be externally connected, wherein the wire connection contacts are formed as wire-wrap contacts, which are arranged in at least two rows, wherein the wire-wrap contacts of the different rows are arranged offset to one another.
• the contact elements are uniform, wherein the wire-wrap contact is aligned asymmetrically to the fork contact and the contact elements are arranged alternately rotated by 180 ° about the longitudinal axis of the contact element in the connector.
• the contact element may be formed in one piece or be produced by joining the fork contact and the wire-wrap contact, for example by laser or resistance welding or adhesive bonding with electrically conductive adhesive, or even positive and non-positive.
• the one-piece embodiment has the advantage of simple manufacturing, whereas the assembly offers the advantage of producing the two contacts of different materials, which are then optimized in each case to the respective requirements.
• a fork contact can be equipped with different wire wrap contacts.
• the contact elements are arranged captively in the plastic housing.
• the fork contact on a stop edge, which is supported in the housing.
• the Anschalt mechanism be absorbed when Beschaltten the wire-wrap contacts.
• the plastic housing comprises at least one chamber-shaped region, wherein the fork contacts are completely received in the longitudinal direction of the plastic housing.
• ribs are arranged in the chamber-shaped area on the inner sides, which define guides for the fork contacts, wherein the contact areas of the fork contacts protrude beyond the ribs and the ribs are bevelled in the front region.
• the plastic housing is formed in two parts, wherein the housing parts are locked together, which simplifies the support of the contact elements in the housing.
• Fig. 1 is an exploded view of a connector for

• the connector 1 comprises a first housing 10, a second housing part 20 and a plurality of contact elements 30, in the example shown seventeen.
• the contact element 30 has in each case two connection sides, wherein one connection side is designed as a fork contact 31 and the other connection side is designed as a wire-wrap contact 32.
• the fork contact 31 on a leg 33 which projects beyond the one side and forms a stop edge 34.
• the wire-wrap contact 32 is arranged. In this case, the leg 33 is cut free laterally, so that the wire-wrap contact 32 has the largest possible contact surface with the leg 33.
• the first housing part 10 has two rows of openings 11, 12, wherein the openings 11 of the upper row are offset from the openings 12 of the lower row, namely the distance between two fork contacts 31.
• the distance between two openings 11 or 12 of a row then has another, larger pitch. and is for example as large as twice the pitch of the fork contacts 31 on the circuit board 40. This increases the distance of the wire-wrap contacts 32 of the same and different rows, so that there is sufficient space for a connection tool.
• the first housing part 10 has three latching openings 14, which correspond to three latching lugs 21 of the second housing part 20.
• the second housing part 20 has chambers 22 into which the fork contacts 31 are inserted.
• the chambers 22 are preferably formed with non-visible webs, which are rounded or bevelled in the front region to the circuit board 40 out to facilitate the Aufsteckvorgang on the circuit board 40.
• the contact regions 35 of the fork contacts 31 project beyond the webs, so that contact with the printed circuit board 40 is ensured.
• the contact elements 30 are pushed with their wire-wrap contacts 32 in the first housing part 10 through the ⁇ ffnugnen 11, 12, in which case the contact elements 30 abut with the edge 36 inside the first housing part 10.
• the second housing part 20 is then pushed, the fork contacts 31 penetrate into the chamber 22 and the first and second housing part 10, 20 finally lock together.
• the process can also be reversed, that is, first the contact elements 30 are inserted into the second housing part 20.
• the second housing part 20 also has two more latching hooks 23, by means of which the connector 1 in another housing can be engaged, as described in DE 102 57 308 B3.
