Description

The invention relates to a press-in contact for producing an electrical and mechanical connection, comprising a base body, a press-in section and a tip section, the press-in section being at least partially lens-shaped and comprising a first and second contact leg, which are both with the base body and axially opposite with the Tip section are integrally connected.

From the DE 10 2010 033 079 A1 results in an electrical press-in contact with a first section, a second section and a third section. The first section forms a press-in zone for pressing into a plated-through hole in a printed circuit board, the second section forms a solid area and the third section forms one for the continued connection of a lead frame and / or a busbar and / or a pin contact and / or a spring contact. The three sections are connected to one another using the same material, the outer radii of the contact legs being provided with embossed depressions and / or elevations. Furthermore, the embossed depressions and / or elevations begin above the largest enveloping circle diameter of the press-in zone and form an undercut.

The object of the present invention is to propose an alternative press-in contact.

This object is achieved by a press-in contact with the features of claim 1. Preferred or advantageous embodiments of the invention result from the subclaims, the description below and the attached figures.

A press-in contact according to the invention for establishing an electrical and mechanical connection comprises a base body, a press-in section and a tip section, the press-in section being at least partially lenticular and comprising a first and second contact leg which are connected in one piece to the base body and axially opposite to the tip section are, wherein the two contact legs of the press-in contact are connected to one another via a connecting web, and wherein at least two edge sections running at least in sections in the longitudinal direction are formed on the outer radii of the contact legs. In other words, the contact limbs spatially delimit the connecting web, the connecting web being at least partially curved, in particular at least partially concave, on both free surfaces.

The two contact legs are preferably essentially convex. The connecting web adjoins the inner sides of the contact legs and the edge sections are formed on the outer sides or on the part-circular outer radius.

The edge sections on the outer radius of the respective contact leg are designed such that the press-in contact generates a non-positive fit between the press-in contact and the circuit board or the board during a press-in process into a circuit board or a circuit board. Depending on the outer shape of the press-in section, the contact sections extend over at least part of the axial length of the press-in section. In particular, the edge sections are formed on the press-in contact in the area with its greatest width in order to ensure optimal contact with the printed circuit board. The larger the outer radius, the longer the edge sections can be, so that the contact area of the parts that come into contact with one another is increased and an electrical connection is ensured.

The press-in contact is preferably made of a material with essentially the same thickness. In particular, the press-in contact is produced from a sheet metal or a wire by means of stamping and stamping. A precisely fitting shape is achieved, for example, in that a molded part is pressed into a corresponding calibration die designed as a negative shape, so that the press-in contact assumes the cross-sectional shape of the calibration die. As a result, series production of the press-in contact is improved.

Further measures improving the invention are shown below together with the description of a preferred embodiment of the invention with reference to the two figures. Show it

• 1 is a schematic view of a press-in contact according to the invention according to a preferred embodiment, and
• 2nd is a schematic perspective view of the press-in contact according to the invention 1 .

According to the 1 and 2nd includes a press-in contact 1 a basic body 2nd , a lenticular press-in section 3rd and a tip section 4th . The press-in section 3rd is axially adjacent between the base body 2nd and the tip section 4th arranged and connected in one piece with it. The press-in section 3rd has a first and second contact leg 3a , 3b on that via a connecting bridge 3c are interconnected. Hence is the connecting bridge 3c through the main body 2nd , the two contact legs 3a , 3b as well as the tip section 4th limited space and connected in one piece. The press-in contact is present 1 related to a longitudinal axis A axially symmetrical.

The press-in contact 1 is essentially made from sheet metal by stamping and embossing, the main body 2nd who have favourited Contact Legs 3a , 3b of the press-in section 3rd as well as the tip section 4th have substantially the same thickness. Only the connecting bridge 3c has a smaller thickness. In the present is the connecting bridge 3c essentially on both sides, that is to say concave on its two free and opposite surfaces.

The press-in contact 1 is made of a copper alloy. Alternatively, the press-in contact 1 can also be formed from a bronze alloy. The press-in contact 1 thus has a particularly high electrical conductivity.

Due to the essentially lenticular outer structure of the press-in section 3rd the contact legs run 3a , 3b along a pitch circle and point to the connecting web 3c opposite side a respective outer radius 5a , 5b on. On the outer radii 5a , 5b the contact leg 3a , 3b are in the area of the widest point of the press-in section 3rd two longitudinally and substantially parallel edge sections 6a , 6b trained, between which one in 2nd notch shown 7 is trained. Through the edge sections 6a , 6b of the respective outer radius 5a , 5b , which run essentially parallel to one another, ensures that between the press-in contact 1 and a printed circuit board - not shown here - is press-fitted.
