Definitions

  • the invention relates to a plug-in contact for electrically contacting a circuit board by inserting the plug-in contact into a contact hole in the circuit board, with two contact legs that are resilient relative to one another, a connection area and a connection area, the connection area connecting the two contact legs to one another and to the connection area, and the plug-in contact is formed from a metallic flat material.
  • the invention also relates to an electrical connection terminal with a housing, with a conductor connection element and with a busbar piece, wherein a conductor to be connected can be electrically connected to the busbar piece by means of the conductor connection element and a conductor insertion opening is formed in the housing for inserting an electrical conductor to be connected.
  • Plug contacts for producing electrical connections between conductors, various electrical or electronic components and busbars are known in various embodiments and for various areas of application.
  • the plug contacts are inserted into corresponding receiving contacts or socket elements, whereby the receiving contacts can be openings in busbars, for example.
  • the plug contacts themselves can be connected to electrical components or provided for connection to electrical conductors, for which purpose the connection area of the plug contacts is then designed accordingly.
  • connection terminals have also been known in a variety of design variants for decades.
  • the connection terminals can, for example, be designed as a so-called printed circuit board for connecting an electrical conductor or several conductors to a circuit board, for which purpose the connection terminals have corresponding contact pins which are pressed or soldered into corresponding holes in the circuit board.
  • a screw terminal can be provided as a conductor connection element, through which a conductor to be connected can be connected to the busbar piece in an electrically conductive manner.
  • the conductor connection element can also be designed as a crimp connection to which the stripped end of a conductor to be connected can be attached, the crimp connection then being formed at one end of the busbar piece and the contact pin at the other end of the busbar piece.
  • a cutting connection in which an insulated end of a conductor is pressed into the cutting edges of the cutting connection, is also possible as a conductor connection element.
  • Clamping springs can also be used as conductor connection elements, with both loop-shaped clamping springs, so-called tension spring clamps, as well as U-shaped or V-shaped clamping springs being used.
  • Rigid conductors or conductors with a ferrule can be inserted directly into U-shaped or V-shaped clamping springs, ie without the clamping point having to be opened beforehand with a tool.
  • U-shaped or V-shaped clamping springs With the known U-shaped or V-shaped clamping springs, the conductor to be connected is pressed against the busbar piece by the clamping leg of the clamping spring, whereby the electrical connection between the conductor and the busbar piece is established.
  • the clamping point between the clamping leg and the busbar piece must be opened, for which purpose an actuation opening for inserting a tool, for example the tip of a screwdriver, is formed in the housing.
  • the actuation opening also serves to open the terminal point in order to be able to pull a connected conductor out of the terminal again.
  • a plug contact designed for use in circuit boards has been known for some time, which is designed in the manner of a spring fork and has two flat contact legs that are resilient relative to one another and which are connected to one another via a common connection area.
  • the plug contact is punched out of a metallic flat material and bent, with the narrowest possible area between the contact legs being punched out to produce the two contact legs.
  • the contact legs When plugged in, the contact legs each press with their outer punched edges against the inner wall of the contact hole into which the plug contact is inserted.
  • the connection area opposite the contact legs is designed as a crimp connection, so that one conductor can be connected to a plug contact.
  • the two contact legs In order for the two contact legs to be manufactured safely using stamping technology, their width must approximately correspond to their thickness, i.e. H. the material thickness of the flat material from which the plug contact is punched out. Since the width of the area punched out between the two contact legs also corresponds approximately to the material thickness of the flat material, it results that the width of the individual contact legs is only just under 1/3 of the total width of the plug-in contact.
  • the total width of the plug contact i.e. H.
  • the width of the two contact legs and the width of the area punched out between the two contact legs is determined by the diameter of the contact hole in the circuit board into which the plug contact is to be inserted. With small hole diameters, this means that the contact legs of the plug contact have to be very narrow and thin. This is initially difficult to achieve in terms of stamping technology and also means that the normal contact force that can be applied by the contact legs is only relatively low.
  • a plug-in connection does not produce such an intermetallic connection.
  • the contact partners ie the plug contact and the contact hole in the circuit board, press against each other with the normal contact force. This must be sufficiently large to ensure good and permanent electrical contact between the contact partners. Are the contact legs too narrow? or too thin, the contact normal force may not be large enough to ensure long-term good electrical contact.
  • the US 4,384,757 discloses a plug contact with two resilient contact legs for insertion into a contact hole on a circuit board.
  • the plug-in contact is bent from a flat material, with a connection area forming a U-shaped contour together with the resilient contact legs.
  • the two contact legs are bent in the longitudinal direction.
  • the FR 2 813 997 shows a plug contact, according to the preamble of claim 1, in which the distance between the two contact legs in the contact area is smaller than in the connection area.
  • the contact legs of this plug contact are curved in cross section in the contacting area.
  • connection terminal with several plug contacts described above is from the DE 10 2011 011 017 A1 known.
  • the individual plug contacts are arranged next to each other in several rows in chambers of the connection housing in such a way that the plug contacts extend perpendicular to the plane of the circuit board.
  • the connection areas of the individual plug contacts are designed as crimp connections. This allows several conductors to be connected to a circuit board in which the individual contact holes are at a small distance from one another. However, subsequent connection or disconnection of individual conductors is not possible with the known connection terminal.
  • a fork-shaped plug contact for contacting a circuit board is also available DE 202 18 295 U1 known.
  • the contact legs press with their outer punched edges against the inner wall of the contact hole, with the two contact legs each having two outer edges, which dig into the metallization of the hole wall when the plug-in contact is pressed into the contact hole of the circuit board.
  • Cold welding should preferably occur between the metallization of the bore wall and the contact leg in order to ensure good electrical contact.
  • a subsequent separation of the connection is then not possible or only possible with difficulty.
  • the present invention is based on the object of providing a plug-in contact described above, which ensures secure contacting of the contact hole even when the material thickness of the flat material is small so that the connector ensures good and permanent electrical contact between the contact partners.
  • the plug contact should also be able to be pulled out of the contact hole again.
  • an electrical connection terminal is to be specified with which an electrical conductor can be easily connected to a circuit board.
  • the two contact legs each have a first section and a second section adjoining it in the insertion direction of the plug-in contact.
  • the two contact legs are bent out of the plane of the connection area in such a way that the connection area and the first areas of the two contact legs adjacent to the connection area together form a U-shaped contour.
  • the contacting areas that contact the contact hole when the plug-in contact is inserted are formed on the outer sides of the second sections of the two contact legs facing away from one another, with each contact leg having a contacting area.
  • the contact legs and the connection area do not extend in a common plane, but the contact legs are bent relative to the connection area. This results in the contact legs in the inserted state not pressing against the inner wall of the contact hole with their punched edges, but with their outer sides of the second sections facing away from one another. This ensures that the contact area of the contact legs is no longer directly dependent on the material thickness of the metallic flat material from which the plug contact is made.
  • the design of the contact legs in particular their geometry and the shape of the contacting areas, there is more scope for design, so that the plug contact and in particular the contact legs can be better adapted to the respective dimensions of the contact hole.
  • the contacting areas of the contact legs are not formed on their punched edges but on the rolled side of the metallic flat material, the Contacting areas can be provided with a coating in a simple manner, for example gold-plated. Since the contacting areas are not formed on the punched edges, the coating can already be applied to the metallic flat material from which the plug contacts are made, ie punched out and bent. This eliminates the need for subsequent and complex coating of the individual plug contacts that have already been punched out and possibly bent.
  • the second sections of the two contact legs each have an outer contour with a rounded cross-section, at least in their contacting area.
  • the edges of the contact legs are therefore machined, particularly in the area in which the contact legs contact the contact hole when inserted, so that they do not have any sharp edges that dig into the metallization of the bore wall when the plug contact is inserted into the contact hole.
  • the outer contour of the contact legs can have a radius that is smaller than the radius of the contact hole. This makes it possible to insert and remove the plug contact several times without causing major damage to the inner wall of the contact hole in the circuit board.
  • the contacting areas of the two contact legs are designed to be spherical. The spherical shape of the contacting areas can be easily created using a die into which the corresponding areas of the second sections of the contact legs are pressed before the contact legs are bent out of the plane of the connection area.
  • the geometry of the contact legs can be more easily adapted to the respective requirements, in particular to the dimensions of the contact hole .
  • the two contact legs are arranged mirror-symmetrically to one another, with a distance from one another over their entire longitudinal extent.
  • the contact legs are bent in such a way that the distance between the two contact legs from one another is the smallest in the area of their free ends.
  • connection area is also the same for plug-in contacts that are designed to be inserted into contact holes are provided with small diameters, can have a width that ensures sufficient stability of the plug contact.
  • the two contact legs also each have a smaller width in their contacting area than in their first section. This also creates the possibility of providing a plug-in contact that can be inserted into contact holes with a small diameter , without the overall width of the contact legs having to be chosen correspondingly small. This makes the production of the plug-in contact easier because the contact legs do not have to be too narrow in the section in which they are bent away from the connection area. In addition, the normal contact force that can be applied by the contact legs is not too low, so that long-lasting, good electrical contact can be guaranteed even with low material thickness.
  • the electrical connection terminal has a plug contact according to the invention, which is at least partially arranged in the housing of the connection terminal in such a way that the busbar piece is formed by the connection area or a section of the connection area of the plug contact, the contact legs of the plug contact having their second sections or their contacting areas protrude from the bottom of the housing.
  • the underside of the housing is the side that faces the circuit board when the connection terminal is placed on the circuit board.
  • connection terminals can be used in connection terminals with different connection techniques.
  • a screw terminal or an insulation displacement terminal can be provided as a conductor connection element, through which a conductor to be connected can be electrically connected to the busbar piece.
  • the conductor connection element can also be designed as a crimp connection to which the stripped end of a conductor to be connected can be attached.
  • a clamping spring is provided as the conductor connection element, which has a clamping leg and a contact leg, the clamping leg together with the corresponding section of the connection area of the plug contact forming a spring-loaded clamping connection for the conductor to be connected.
  • the use of a clamping spring as a conductor connection element has the additional advantage that a conductor to be connected can be connected very easily to the connection terminal and thus also to a circuit board via the spring-loaded clamp connection. If necessary, the electrical conductor can also be pulled out of the connection terminal again when the spring-loaded terminal connection is opened. The electrical connection between the conductor and the circuit board can thus be released both between the conductor and the connection area of the plug contact and between the contact legs of the plug contact and the circuit board.
  • connection area of the electrical connection terminal extends in the longitudinal direction of the contact legs
  • the conductor insertion opening is arranged on the top of the housing and an electrical conductor to be connected is inserted into the connection terminal perpendicular to the plane of the circuit board.
  • connection area of the plug contact it is also possible for the connection area of the plug contact to be bent perpendicularly - or at an angle not equal to 90° - to the longitudinal direction of the contact legs, so that the conductor insertion opening is then arranged accordingly on an end face of the housing. In both cases, the electrical conductor is pressed from the free end of the contact leg against the corresponding section of the connection area, whereby the electrical connection between the conductor and the plug contact is established.
  • connection area of the plug contact facing the clamping leg.
  • connection area increases the surface pressure between the inserted conductor and the plug contact, which leads to a lower contact resistance.
  • a plurality of adjusting elements are formed on the underside of the housing, which are inserted into corresponding recesses in the circuit board when the connection terminal is placed on the circuit board.
  • the ends of the adjusting elements are preferably conical, which makes it easier to insert the adjusting elements into the corresponding recesses in the circuit board.
  • the length of the adjusting elements is selected so that when the connection terminal is placed on the circuit board, the adjusting elements first engage with their free ends in the corresponding recesses in the circuit board before the contacting areas of the contact legs of the plug-in contact dip into the corresponding contact holes in the circuit board.
  • At least two locking elements are formed on the underside of the housing, which engage in corresponding recesses in the circuit board.
  • Appropriate locking projections or locking lugs can be used to ensure that the electrical connection terminal is securely attached to a circuit board after it has been placed on it.
  • the latching elements are preferably designed in such a way that they can be transferred from a first, non-latching state to a second, latching state and vice versa. This makes it possible to release the latching between the housing of the electrical connection terminal and the circuit board again, so that the electrical connection terminal can be lifted off the circuit board again if necessary.

  • the contact areas 4c, 5c are spherical.
  • the radius of the outer contour of the contact areas 4c, 5c is slightly smaller than the radius of the contact hole 3, so that when the contact legs 4, 5 are inserted into the contact hole 3, the metallized inner wall of the contact hole 3 is not damaged.
