Definitions
- the present invention relates to an SMD (surface-mounted device; surface-mounted component) terminal, in particular an SMD connection terminal or SMD connection terminal and an SMD terminal arrangement which has the SMD terminal and which also has a printed circuit board on which the SMD Clamp (s) is / are surface-mounted.
- SMD surface-mounted device; surface-mounted component
- Connection terminals or connection terminals are sufficiently known from the prior art. On the one hand, these can be provided loosely and, if necessary, fastened, for example, by means of connecting elements (for example snaps, screws, adapters, etc.). It is also conceivable to provide these terminals on a printed circuit board. This is done, for example, by means of through-hole assembly (THT), in which wire connections (solder pins) of the terminal are inserted through contact holes in the circuit board and then soldered on the back to a conductor track on the circuit board. Alternatively, for example, also by means of surface mounting (surface-mounted technology; SMT), in which the component is soldered as a surface-mounted device (SMD) by means of flat connection areas (contact lugs) directly on the side of the component on the circuit board.
- TTT through-hole assembly
- SMT surface-mounted technology
- SMD surface-mounted device
- the current-carrying components when using such terminals for the network area, but also for other purposes, there are different high demands on the given clearance and creepage distance.
- the current-carrying components therefore also the contact bodies of the respective terminal, must be laterally spaced accordingly.
- the air and creepage distances can be increased.
- a higher-level, insulating assembly housing e.g. a lamp housing
- the present invention relates to an SMD terminal, in particular an SMD connecting terminal or SMD connecting terminal.
- the SMD terminal has a contact body.
- the contact body in turn has a clamping body with a clamping point for fastening an electrical conductor in an insertion direction.
- the contact body has a flat connection area extending in one plane for surface mounting of the SMD terminal on a printed circuit board.
- the SMD terminal also has an insulation wall which extends along at least part of the contact body (preferably at least the clamping body) in a laterally limiting manner with respect to the insertion direction in such a way as to provide a projection section (i.e. a projection wall section or) on a side of the plane facing away from the contact body .
- Protrusion insulation wall section protrude.
- the latter in particular in order to lengthen a clearance and creepage distance of two identical SMD terminals arranged laterally with respect to the insertion direction in a row next to one another compared to comparable SMD terminals without such a protruding section.
- the SMD terminal thus carries an element that extends air and creepage distances (namely the insulation wall extended into the protruding section, which consequently also forms a wall section), which is automatically provided between them when several such SMD terminals are installed next to one another in series.
- air and creepage distances namely the insulation wall extended into the protruding section, which consequently also forms a wall section
- the SMD terminal can furthermore have a further insulation wall which laterally delimits the contact body on a side facing away from the contact body of the insulation wall, the further insulation wall also delimiting laterally along at least part of the contact body (preferably at least the clamping body) with regard to the insertion direction extends in such a way as to protrude on a side of the plane facing away from the contact body with a further protrusion section (that is to say a more comparable protrusion wall section or protrusion insulation wall section). Consequently, the protruding section and the further protruding section then protrude on the same side with respect to the plane as a wall section and thus form a corresponding measure to lengthen air and creepage distances on both sides of the contact body.
- the present invention also relates to an SMD terminal, in particular an SMD connecting terminal or SMD connecting terminal, which has at least two or more contact bodies.
- the contact bodies in turn each have a clamping body with a clamping point for fastening an electrical conductor in an insertion direction and a flat connection area extending in one plane for surface mounting of the SMD terminal on a circuit board.
- the connection areas of at least one, several or all of the contact bodies preferably extend essentially in the same plane.
- an insulation wall laterally separating at least part of the contact bodies (preferably at least their clamping bodies) extends in such a way as to provide a projection section (i.e. a protruding portion (i.e. a Protrusion wall section or
- Protrusion insulation wall section protrude.
- the latter in particular in order to lengthen a clearance and creepage distance in each case between two adjacent contact bodies of the SMD terminal in comparison to such contact bodies of an SMD terminal without such protrusion sections.
- an SMD terminal which has several contact bodies, two adjacent or each contact body being electrically insulated laterally from the respective adjacent contact body in such a way that an insulation wall providing the insulation also protrudes from the plane described above, thus around an air - and to lengthen the creepage distance between the contact bodies adjacent in this way with respect to an SMD terminal in which the projection sections would not be provided.
- the SMD terminal itself can directly bring the air and creepage distances lengthening measures (namely the insulation wall extended into the protruding section, which consequently also forms a wall section), so that these are automatically made available when the same is installed.
- the directions of insertion of the contact bodies are preferably aligned parallel to one another.
- a particularly compact and easy-to-use SMD terminal can thus be provided.
- the insertion direction of the simple SMD terminal according to the first aspect or the insertion directions of the SMD terminal according to the second aspect can accordingly extend or be aligned parallel to the plane, which can lead to a particularly compact design and also compact operability, because the corresponding electrical conductors can be fed flat in the plane of the corresponding SMD terminal.
- the contact bodies can be arranged laterally in a row next to one another with respect to the insertion directions and can be distributed preferably parallel to the plane. In this way, an SMD terminal can be provided with any number of contact bodies arranged side by side and thus in a particularly compact manner. Due to the arrangement distributed parallel to the plane, the use of identical parts for the contact bodies is particularly easy, since these then, for example, provide the connection areas in the same way for surface mounting, which in turn easily enables a connection via the connection areas preferably provided in the same plane.
- the SMD terminal can furthermore have at least one further insulation wall which laterally delimits at least one or at least two further insulation walls which at least both outer contact bodies of the contact bodies arranged in series on a side facing away from the contact body of the insulation wall, with the other Insulation wall also extends along at least part of the associated contact body (preferably the associated clamping body) in a laterally limiting manner with respect to the insertion direction so as to protrude on a side of the plane facing away from the contact body with a further projection section.
- At least one further insulation wall with a further protruding section on one side of the SMD terminal makes it possible to provide an SMD terminal which can be combined in any number in series with other similar SMD terminals, the SMD terminal at the same time as a partition to the neighboring SMD terminal. If a corresponding further insulation wall with a further protruding section is arranged opposite one another on both sides, it can also be made possible, regardless of the design of adjacent electrical components, to bring a measure that extends the air and creepage distances directly with them.
- the insulation walls that is to say the insulation walls preferably including the further insulation walls, are preferably aligned parallel to one another.
- a largely symmetrical configuration of the interconnected contact bodies can be provided.
- this enables simple production of the SMD terminal.
- a clear and reliable delimitation of the contact bodies can easily be provided by means of appropriate insulating measures.
- the parallel configuration offers a particularly compact design of a corresponding SMD terminal.
- At least the further protrusion sections and preferably the entire further insulation wall can preferably be narrower than and preferably half as wide as the or one of the insulation walls or at least their protrusion sections when viewed transversely to their direction of extension or transversely to the insertion direction of the associated contact body.
- the outer wall areas of the clamp can be made narrower, so that when clamps of the same type are arranged in a row, a combined width of the insulation walls results in the area between the clamps.
- a sufficient clearance and creepage distance can also be made possible in the contact area between two adjacent terminals.
- the insulation wall (s), preferably also the further insulation wall (s) insulation walls, can preferably extend in such a way that they extend along at least that part of the associated contact body which extends most laterally outward transversely to the insertion direction and parallel to the plane - than towards the isolation wall - extends.
- the insulation wall can be provided in a preferred area to extend a clearance and creepage distance of the SMD terminal.
- Isolation wall (s) can extend in the insertion direction along the entire clamping body or contact body adjacent to it, preferably protrude over the clamping body with respect to the insertion direction in and / or opposite to the insertion direction and more preferably protrude over the entire contact body. In this way, the clearance and creepage distance can be set in any way.
- connection area preferably extends essentially parallel to the respective insertion direction.
- a compact design of the respective contact body and thus of the SMD terminal as a whole can be achieved when viewed transversely to the insertion direction.
- Each of the clamping bodies can have a contact frame as well as a clamping spring held therein for preferably tool-free and further preferably detachable reception of an electrical conductor introduced in the insertion direction.
- the SMD terminal can also have an insulating housing in which the contact body or bodies are at least partially accommodated. To enable the SMD terminal to be connected to a printed circuit board, the connection areas are exposed to the outside with respect to the insulation housing.
- the insulation wall / insulation walls and further preferably the further insulation wall / insulation walls can be formed integrally with the insulation housing.
- the insulation wall can be formed integrally in a simple manner with an insulation housing receiving the contact bodies, which simplifies the production of the insulation areas and thus the SMD terminal as a whole.
- the present invention also relates to an SMD terminal arrangement.
- This has at least one of the SMD terminals according to the invention.
- the SMD terminal arrangement also has at least one circuit board with the connection point corresponding to the connection area of the SMD terminal or connection points corresponding to the connection areas of the SMD terminal, via which the SMD terminal (s) are connected to the circuit board in surface mounting, the circuit board for each protrusion section (that is, for each protrusion section and, if present, furthermore for each further protrusion section) has a recess into which the respective protrusion section protrudes.
- the SMD terminal can be provided in a flat and compact manner on the circuit board in a surface-mounted manner, while at the same time the clearance and creepage distance lengthening measures, namely the projection portions, are provided safely and automatically. Consequently, the projection sections do not impair the mounting of the SMD terminal on the circuit board.
- the recess or recesses are preferably designed as through openings, that is to say they extend through the printed circuit board in particular transversely to its generally flat direction of extent.
- the projection section (s) then preferably project at least partially into the respective through opening or completely protrude through the circuit board via the through opening.

- These protrusion sections 40 can be clearly seen, for example, in FIGS. 6 and 7 and are provided here as wall sections or webs protruding from the underside. The protrusion sections 40 thus form the corresponding protruding section of the insulation wall 4.
- these projection sections 40 are consequently designed in such a way that they extend an air gap and creepage distance between adjacent contact bodies 3; in comparison to the same SMD terminals without corresponding protrusion sections 40.
- the insertion directions E of the contact bodies 3 are preferably all aligned parallel to one another. As can also be easily seen from FIGS. 1, 7 and 9, the insertion directions E preferably all extend parallel to the plane X.
