Description

[0001] The invention relates to an optoelectronic component according to claim 1 and a conductor frame according to claim 7.

[0002] From DE 10 2012 101 970 A1, a conductor frame unit for an electronic component is known, which has two contact carrier elements that are integrally formed with at least one retaining web. The two contact carrier elements are connected to conductor frame units via retaining webs. The retaining webs are arranged at least partially at the same distance from the corner regions of the rectangular conductor frame unit. This creates the risk that, when several components are arranged side by side, the support arms projecting from the component may touch each other. Therefore, it is necessary to maintain a relatively large distance between the components.

[0003] The object of the invention is to provide an improved optoelectronic component and an improved conductor frame for the manufacture of an optoelectronic component.

[0004] The object of the invention is solved by the optoelectronic component according to claim 1 and by the conductor frame according to claim 7.

[0005] Further advantageous embodiments are specified in the dependent claims.

[0006] The component is designed such that, at least on two sides of the housing, the support arms of a contact element have different distances to the two corner points of the housing sides. These distances differ by at least the width of one support arm. This allows two components to be arranged side by side rotated by 90°, 180°, and / or 270° without the risk of the support arms touching. Thus, the components can be mounted closer together on a carrier.

[0007] Depending on the chosen design, the two sides are arranged side by side or opposite each other.

[0008] In a further embodiment, the component is designed such that the support arms on all four sides of the housing have different distances to the respective two corner points of the side on which the support arms are arranged. This makes it possible to arrange one component next to another, with the latter rotated by 90°, without the support arms of the two components touching each other. This also makes it possible to arrange the components closely together on a support, even rotated by 90°, without the risk of electrical contact between the support arms.

[0009] The invention will be explained in more detail below with reference to the figures.

[0010] The properties, features and advantages of this invention described above, as well as the manner in which they are achieved, will become clearer and more easily understood in connection with the following description of the exemplary embodiments, which are explained in more detail in conjunction with the drawings, wherein
