Definitions
- the invention relates to a one-piece contact spring with a box-shaped contact part with a top wall, side walls and a bottom wall, of which at least one spring arm at the insertion opening is bent back into the interior of the contact part, which forms a plug contact socket with at least one further spring arm.
- Contact springs are generally known. They are preferably used as connectors in motor vehicle technology in order to form detachable contact points where increased contact security is important.
- Known contact springs are generally designed in several parts in order to ensure the aforementioned contact reliability in this way, in particular by combining different materials.
- a box-shaped contact part is often provided, which has in its inner resilient contact tabs that cooperate with the mating contact in question.
- a contact spring designed as a contact socket which has a contact part bent from one piece, the integrated spring arms of which are acted upon by additional springs, in order to ensure the necessary contact reliability.
- the additional springs are welded to the spring arms and are permanently and permanently connected in this way.
- the contact part is stamped out of a corresponding sheet. processed and bent into the final contour in several bending operations, with the additional spring being inserted between them, which in the finished state are integrally connected to the spring arms.
- the constructive design of the known contact spring provides spring arms opening towards the front, which are integrally formed on the rear end of the contact part. This results in a limited spring action due to the limited spring travel, which can only be compensated for by means of the additional spring element.
- the spring arm bent back into the interior of the contact part is integrally formed on the short side of the bottom wall or a side wall, that at least two further spring arms are formed on the side at the free end of the bent spring arm and bent at an angle, preferably at right angles, and with their free ends extend to the insertion opening and forms a receptacle for a mating contact.
- the spring arms are each provided with bulges which face one another and thereby narrow the insertion cross section for a mating contact accordingly, so that the spring arms are pushed apart when inserted.
- This deflection from the rest position the spring arms expediently also being prestressed in the rest position, increases the restoring force of the spring arms and thus their contact force.
- two longitudinally folded side walls are formed on the bottom wall and the longitudinally folded top wall is formed on one side wall, each of the walls forming a right angle with respect to the adjacent walls and their free edges abutting so that they meet with the Bottom wall form a closed box profile with a rectangular cross-section.
- only three walls namely a bottom wall and two side walls, are provided.
- the side walls along the bottom wall are folded so far that their free edges meet and form a closed box profile with a triangular cross-section with the bottom wall.
- the cross section can also be round on the outside and triangular on the inside.
- a contact spring is assigned to each side wall and the bottom wall, their bulges also touching one another and forming a defined contact surface for a pin-shaped mating contact.
- the bulges of the spring arms are preferably arranged at the same distance from the insertion opening.
- each spring arm has a mechanical support, which is arranged on both sides of the bulge of the spring arm in question and cooperates with the side wall assigned to this spring arm.
- the mechanical support of the contact spring formed on the bottom wall is advantageously formed on the one hand by the bend on the bottom wall and on the other hand by contact with the bottom wall.
- the mechanical support of the further spring arms, which are formed on the bent-back free end of the contact spring formed on the bottom wall, is achieved in that they are supported in front of and behind the bulge on the associated side wall.
- the further spring arms preferably have, at their free end facing the insertion opening, a centrally formed projection which engages in a recess formed in the associated side wall and thus forms a mechanical support for the contact springs.
- the spring arm in question is guided by the neck-shaped projection formed on it in the recess in the side wall to the height and side, while the shoulder-like lateral contact surfaces are supported on the edge of the recess, that is to say on the side wall.
- connection device for a connection cable is provided, which is preferably designed as a crimp connection or as an IDC connection.
- a further advantageous embodiment of the contact spring according to the invention is that the free longitudinal edges of the side walls of the contact part are connected to one another in a form-fitting manner, so that in addition to the bending resistance of the material of the contact part, a form resistance must be overcome in order to damage the integrity of the contact part.
- This is achieved in that the free longitudinal edges of the side walls engage by means of tabs formed on a free longitudinal edge of the one side wall of the contact part in slots formed next to the free longitudinal edge of the corresponding side wall of the contact part.
- the tabs formed on a free longitudinal edge of the one side wall of the contact part reach through the slots formed next to the free longitudinal edge of the corresponding side wall of the contact part and are possibly bent over.

- FIG. 10 shows a longitudinal section through the contact part of the contact spring according to FIG. 8 and
- FIG. 11 shows an end view of a contact spring with a circular cross section from the insertion side.
- connection part 12 is shown at the rear end with two insulation claws 14 and two conductor wire claws 16, which connection part is connected to a contact part 20 via a connecting web 18.
- the contact part 20, which connects to the connection part 12, is formed from a bottom wall 22, two laterally adjoining side walls 24, 26 and a top wall 28, which are separated from one another in the illustration according to FIG. 1 by bending lines indicated by dashed lines.
- a bending tab 30 is formed on the other side wall 24, which is bent over in the finished state, see FIG. 4, and overlaps the ceiling wall 28.
- a strip 32 connects to the strip connected to the top wall 28 and forms the side wall 26, on the free end of which strip-shaped spring arms 34 are formed on both sides, which in the finished state, that is to say in the finished contact spring 10 take over the contacting with a mating contact, not shown here, the arrows shown indicating the intended bending direction.
- tabs 36 are formed on the front, which in the finished state, that is to say in the finished contact spring 10 according to FIG. 4, serve as back-up protection.
- a tab 38 is integrally formed on the side of the ceiling wall 28, which tab cooperates with a recess 39 which is formed in the side wall 24 which adjoins the ceiling wall in the finished state.
- FIG. 2 the arrangement of FIG. 1 is shown in detail and after a first manufacturing step, according to which the spring arms 34, 36 adjoining the free end of the spring arm 32 are angled by 90 ° parallel to the longitudinal direction of the spring arms 32, 34.
- An arrow indicates the bending direction provided in the next bending step (Fig. 3).
- the spring arms 34 lying opposite one another are each provided with a bulge 33 directed towards one another, that is to say inwards, so that they touch one another (see in particular FIG. 3). This increases the contact force and thus favors the contact reliability of the finished contact spring 10.
- lugs 40 are formed in the center on the end faces, which engage in recesses 42, which are each formed in the bottom wall 22 and in the top wall 28. Because of the sen 40 each the bulge 33 is supported and in this way their bias is ensured so that the contact force remains as constant as possible.
- FIG. 3 The arrangement according to FIG. 1 is shown in FIG. 3, the strip forming the spring arm 32, which adjoins the side wall 26, being bent back differently, so that the spring arms 24, 26 provided with the bulge 33 virtually assume their end position.
- the tabs 36 which serve for rear security, are also bent back in accordance with the arrows shown.
- FIGS. 1 to 3 finally shows a finished contact spring 10 according to the invention, in which the strips forming the side walls 24, 26 and the top wall 28 and the bending tab 30 along the bending lines shown in FIGS. 1 to 3 and running parallel to the longitudinal axis in accordance with the arrows shown are bent.

- FIG. 6 shows a longitudinal section through the contact part 20 of a modified contact spring 11, which is designed similarly to the contact spring 10 shown in FIGS. 1 to 5, but additionally on the bottom wall 22 and on the top wall 28 has indentations 44 attached, which support the spring arms 34.
- FIG. 7 shows the starting material for an alternative embodiment of a contact spring 11 similar to FIG. 1, but with a triangular cross section after punching out of flat material in an oblique view. Since one side less is required here, the punched blank is narrower than that shown in Fig. 1, but the other features are largely retained. Accordingly, the same features which have already been explained are provided with the same reference numbers.
- FIG. 8 shows the finished triangular contact spring 11 according to FIG. 7 after the bending process with a connecting part 12 and a contact part 20 in an oblique view.
- the bulge 33 to increase the contact force and the window 39, into which the lugs 40 integrally formed on the front of the spring arms 34 engage, are provided on the side walls 24 and 26.
- FIG. 9 shows the end view of the triangular contact spring 11 according to FIG. 8 from the insertion side.
- this alternative embodiment of the contact spring 11 according to the invention is preferably provided and particularly suitable for pin-shaped mating contacts, that is to say in particular for slim mating contacts, for example with a circular cross section, since the three side walls 22, 24, 26 or the herewith corresponding spring arms 32, 34, which are each provided with a bulge 33, 35, bear against the mating contact and fix under prestress.
- FIG. 10 shows a longitudinal section through the contact part 20 of the contact spring 11 according to FIG. 8.
- the spring arm 34 shown here is quasi erected, while its flat side is in the cuboidal contact spring 10 according to FIG. 6 is arranged horizontally.
- the rear fuse 36 can also be clearly seen in this view, which prevents an inserted mating contact, not shown here, from coming behind the spring arm 34, that is to say between the spring arm 34 and the associated side wall 26.
- FIG. 11 shows an end view of a further alternative embodiment of a contact spring 46 with a circular cross section from the insertion side.
- This contact spring 46 differs from the previously described contact springs only in the circular cross section. All other features described above can be found here as well as with the other contact springs, so that a detailed description is not necessary.
