Definitions

  • the invention relates to an electrical connection terminal.
  • connection terminals have been known in a variety of embodiments for decades.
  • the connection terminals can be designed, for example, for connection to a further conductor as a terminal block or for connecting an electrical conductor or several conductors to a printed circuit board as a so-called print terminal.
  • Both loop-shaped clamping springs, so-called tension spring clamps, as well as U-shaped or V-shaped clamping springs are used as clamping springs, directly into the rigid conductor or conductor provided with a ferrule, ie. H. can be inserted without first having to open the terminal point with a tool.
  • the clamping point between the clamping leg and the busbar piece must be opened, for which purpose an actuating opening for inserting a tool, for example the tip of a screwdriver, is formed.
  • a tool for example the tip of a screwdriver
  • an electrical connection terminal which is provided as part of a terminal block.
  • the known connecting terminal has an actuating push button which is arranged displaceably in an actuating opening formed in the housing and with which the clamping point can be opened when the actuating push button is pressed into the housing.
  • the actuating button can latch in the position opening the clamping point, so that the Clamping point is held in the open position, whereby a flexible conductor can be inserted into the electrical connection terminal without the actuation button having to be pressed permanently.
  • a plug contact designed for use in printed circuit boards has been known in practice for some time, which is designed in the manner of a spring fork and has two flat, mutually resilient contact legs which are connected to one another via a common connection area.
  • An electrical connector with several such plug contacts is from the DE 10 2011 011 017 A1 known.
  • the individual plug contacts are arranged in several rows next to one another in chambers of the connection housing in such a way that the plug contacts extend perpendicular to the plane of the printed circuit board.
  • the connection areas of the plug contacts are designed as crimp connections.
  • the EP 0 212 330 A2 discloses a connector for electrical devices with a two-part insulating body.
  • the connecting terminal is equipped with a contact spring which comprises a spring leg which, together with a bracket body, form a spring-loaded terminal connection for conductors inserted into a conductor insertion opening.
  • the spring-loaded terminal connection can be operated from the outside using a push button, for which the push button must engage in an opening in the housing.
  • the AT 12 576 U1 discloses a connector for electrical conductors.
  • a contact frame and a spring element together form a structural unit as a contact body.
  • the DE 199 64 616 B4 discloses a terminal for electrically connecting at least one electrical contact part to a conductor wire.
  • the contact part consists of three interconnected tongues, the tongues being designed as a resilient plug contact.
  • the DE 20 2008 010 347 U1 discloses a pluggable PE protective contact.
  • the protective contact has a sharp-edged latching contact lug, which is clamped into a slot in an object housing plate.
  • the latching contact flag has a latching corner contact, which is used for the electrical connection to a conductor connection contact.
  • the present invention is therefore based on the object of providing an electrical connection terminal described at the beginning, with which an electrical conductor can be connected to a printed circuit board in a simple manner.
  • the connection of a conductor or an exchange of the conductor should also be possible on site.
  • the electrical connecting terminal according to the invention has a spring-loaded terminal connection for connecting an electrical conductor and a plug contact for contacting a printed circuit board, both the connection between the connecting terminal and the electrical conductor and between the connecting terminal and a printed circuit board can be produced easily and can also be separated again easily, d. H. Both electrical connections or connection points of the electrical connection terminal are designed to be reversible. Since in the electrical connection terminal according to the invention the connection area of the plug contact provided for the connection of the electrical conductor is not designed as a crimp connection but as a spring-loaded terminal connection, the electrical connection terminal does not have to be assembled with an electrical conductor, but the connection of the electrical conductor can also be made Place or even after the connection terminal is connected to the circuit board.
  • a U-shaped or V-shaped clamping spring is preferably used as the clamping spring, so that a rigid conductor or a conductor provided with a ferrule can be inserted directly into the clamping point.
  • connection area connecting the metal part to the plug contact can be used to decouple the forces occurring when the contact limbs are plugged in and pulled out of the spring-loaded terminal connection if the connection area has a certain flexibility in the axial direction. This can be achieved simply by the connection area running at least partially perpendicularly or obliquely to the longitudinal direction of the contact limbs, so that a slight axial displacement of the contact limbs does not lead directly to a corresponding axial displacement of the metal part.
  • the metal part and the plug contact are preferably formed in one piece with one another, in particular punched out and bent out of a metallic flat material.
  • the forces occurring when connecting a conductor are preferably also mechanically decoupled from the contact legs of the plug contact.
  • Housing formed in two parts, so that it has a first housing part and a second housing part, the first housing part being axially displaceable relative to the second housing part between a first position and a second position.
  • the clamping spring and the metal part are arranged in the first housing part, while the contact legs of the plug contact are arranged axially displaceably in the longitudinal direction of the chamber in a chamber formed in the second housing part.
  • the displacement of the contact leg of the plug contact in the chamber of the second housing part is effected by a displacement of the first housing part from its first position into its second position - or vice versa - the direction of movement of the housing part and the direction of movement of the contact legs being the same.
  • the contact legs of the plug contact are in the chamber of the second housing part, the free ends of the contact legs not protruding from the underside of the second housing part facing away from the first housing part.
  • the contact limbs of the plug contact are thus arranged protected within the second housing part.
  • first housing part If the first housing part is moved from its first position into its second position, not only does the first housing part move relative to the second housing part, but also the contact legs move within the chamber, the free ends of the contact legs moving out of the underside of the second housing part protrude when the first housing part is in its second position.
  • the contact legs can be easily and securely inserted into the contact hole in the printed circuit board by moving the first housing part from its first position to its second position is after the terminal with the bottom of the second housing part has been placed on the circuit board. Since the contact legs are guided in the chamber in the second housing part, tilting of the contact legs is reliably prevented when they are inserted into the contact hole in the printed circuit board.
  • the axial displaceability between the two housing parts is realized safely and simply in that the first housing part has a sleeve-shaped connecting area at the end facing the second housing part, in which the second housing part is guided.
  • the first housing part is thus pushed further over the second housing part when moving from its first position into its second position, or the second housing part is pushed further into the first housing part.
  • At least one stop is formed on the first housing part and at least one corresponding counter-stop is formed on the second housing part and is arranged such that the stop rests on the counter-stop in the second position of the first housing part. This limits the maximum possible axial displacement of the first housing part relative to the second housing part.
  • the stop also defines the maximum extent that the free ends of the contact legs can protrude from the underside of the second housing part. This can ensure that in the assembled state of the connecting terminal with a printed circuit board, the contact legs of the plug contact with a predetermined contact area are located within the contact hole in the printed circuit board.
  • At least one window is preferably formed in the sleeve-shaped connecting region of the first housing part, into which a radially extending projection formed on the second housing part engages. If two windows are formed in the sleeve-shaped connection area on two opposite sides of the first housing part, then the second housing part also has two projections accordingly.
  • the at least one projection - or both projections - has an insertion bevel and a step or edge, the step of the projection abutting the first edge of the window near the second housing part in the first position of the first housing part.
  • the step is spaced from the first edge of the window, in which case the insertion slope is then preferred of the projection rests on the second edge of the window, which is remote from the second housing part.
  • the insertion bevel facilitates the assembly or the plugging together of the two housing parts.
  • the axial displaceability of the first housing part is primarily limited by the abovementioned stop on the first housing part and the corresponding counter-stop on the second housing part.
  • the stop on the first housing part can be realized in a simple manner by the front end face of the sleeve-shaped connecting region, ie the front end face of the first housing part, while the counter stop is formed by a corresponding collar or step on the second housing part.
  • the first housing part can preferably be locked in its first position on the second housing part.
  • the latching between the two housing parts can be realized by the formation of at least one latching lug and at least one corresponding latching recess, the latching lug on the first housing part or on the second housing part and the corresponding latching recess can then be provided accordingly on the second housing part or on the first housing part. It is structurally particularly simple if a radially somewhat extending latching lug is formed on the second housing part, against which the end face of the first housing part bears in the first position of the first housing part.
  • the locking lug on the second housing part is formed by forming a corresponding slope or a step with a relatively low height such that the first housing part can be pushed over the locking lug with little effort due to the elasticity of the sleeve-shaped connecting area and / or the locking lug.
  • At least one stop is formed in the first housing part and at least one corresponding counter stop is formed on the metal part, as a result of which the position of the metal part is fixed in the first housing part. Forces occurring when a conductor is inserted are derived from the metal part into the housing so that they do not affect the contact area between the contact legs of the plug contact and the contact hole in a printed circuit board into which the contact legs are inserted.
  • the stop can, for example be formed as a projection in the first housing part, which cooperates with a corresponding edge of the metal part as a counter-stop. This prevents axial displacement of the metal part when a conductor is inserted into the terminal point or when the terminal point is opened.
  • a corresponding recess can also be formed in the housing, into which a projection formed on the metal part engages.
  • the formation of the at least one stop and the at least one corresponding counterstop ensures that actuating forces acting on the metal part when connecting or disconnecting a conductor are not transmitted to the printed circuit board.
  • At least one adjusting element is formed on the underside of the second housing part facing away from the first housing part, which can be inserted into a corresponding recess in the printed circuit board.
  • the free end of the adjusting element is preferably conical, which facilitates the insertion of the adjusting element into the corresponding recess in the printed circuit board.
  • At least one fixing element is formed on the underside of the second housing part, which is inserted into a corresponding recess in the printed circuit board.
  • the fixing element can be, for example, a locking element which has locking projections with which the housing of the electrical connection terminal can be securely fixed to the printed circuit board.
  • the at least one fixing element can also be designed as a connecting flange, so that the housing can be screwed to a printed circuit board by means of a screw arranged in the connecting flange.
  • the fixing element itself can also function as before have said adjustment element, for example, the front end of the fixing element is conical.
  • the clamping point is not opened by means of a separate actuating tool inserted into the actuating opening, for example the tip of a screwdriver, but with the aid of an actuating push button which is arranged displaceably in the actuating opening is.
  • the actuating button can be moved from a first position, in which the spring-loaded terminal connection is closed, to a second position, in which the actuating button, with its end facing the clamping leg, deflects the clamping leg against the spring force of the clamping spring, so that the spring-loaded terminal connection is opened. Then a connected conductor can simply be pulled out of the terminal point or a flexible conductor can be inserted into the terminal point.
  • the housing 2 the longitudinal extension of which extends in the connecting direction of the conductor 8, has a conductor insertion opening 9 on one end for introducing the electrical conductor 8 to be connected and an actuating opening 10 in which an actuating pushbutton for opening the clamping point is arranged displaceably. Is the nip between the clamping leg 5 and section 7 open, d. H. the clamping leg 5 is deflected against the spring force of the clamping spring 3, a connected conductor 8 can be pulled out of the clamping point and thus also out of the connecting terminal 1.
  • the overall approximately U-shaped metal part 4 is electrically and mechanically connected to a plug contact 12 via a connection area 11, the plug contact 12 having two contact legs 13, 14 which are resilient relative to one another.
  • the connecting region 11 has two connecting webs 11a, 11b, which have a certain flexibility in the axial direction, so that axial forces acting on the contact limbs 13, 14 are transmitted to the metal part 4 only to a reduced extent.
  • the metal part 4 and the plug contact 12 are punched out and bent out of a metallic flat material, so that they can be seen in particular in FIG Fig. 4 recognizable form results.
  • the contact legs 13, 14 serve for insertion into a contact hole 15 in a printed circuit board 16, as is the case here Fig. 2 is recognizable.
  • the first housing part 2a is axially displaceable relative to the second housing part 2b.
  • the first housing part 2a is shown in the first position, the pre-locking position
  • the first housing part 2a is shown in the second position.
  • the two contact legs 13, 14 of the plug contact 12 are located in a chamber 17 formed in the second housing part 2b, so that the contact legs 13, 14 are protected by the second housing part 2b in the pre-locking position.
  • the free ends 13a, 14a of the contact legs 13, 14 in the first position of the first housing part 2a do not protrude beyond the underside 18 of the second housing part 2b facing away from the first housing part 2a. This leads to the fact that when the electrical connection terminal 1 according to Fig. 2b is plugged onto a printed circuit board 16 in the pre-locking position, the free ends 13a, 14a of the contact legs 13, 14 do not yet dip into the contact hole 15.
  • the first housing part 2a is shifted from its first position into its second position, as is the case in Fid. 2b is shown, not only is the first housing part 2a shifted relative to the second housing part 2b, but also the plug contact 12 is shifted relative to the second housing part 2b, so that the free ends 13a, 14a of the contact legs 13, 14 are then from the underside 18 of the second housing part 2b protrude. If the connection terminal 1 is placed on a circuit board 16, the free ends 13a, 14a dip into the contact hole 15 in the circuit board 16, as a result of which the plug contact 12 is electrically conductively connected to the circuit board 16.
  • the first housing part 2a has, at the end assigned to the second housing part 2b, a sleeve-shaped connecting region 19, in which the second housing part 2b is guided.
  • the first housing part 2a is thus - as from a comparison of the Figures 2a and 2b can be seen - when moving from the first position to the second position, pushed further over the second housing part 2b in the direction of the guide plate 16.
  • a stop is formed on the first housing part 2a, which is formed by the end face 20 of the connecting region 19 or the first housing part 2a.
  • the second housing part 2b has a collar 21 as a counter-stop, the end face 20 abutting the collar 21 in the second position of the first housing part 2a.
  • two windows 22 are also formed on opposite sides of the housing part 2a, into which a radially extending projection 23 of the second housing part 2b engages in the assembled state of the two housing parts 2a, 2b.
  • the two projections 23 each have an insertion bevel 24 and a step 25, which directly adjoins the insertion bevel 24.
  • the insertion bevel 24 runs in the plug-on direction of the first housing part 2a, so that due to the elasticity of the projections 23 and the sleeve-shaped connecting region 19, the first housing part 2a for connection to the second housing part 2b simply runs through the insertion bevel 24 into FIG Fig. 1 and Fig. 2a shown pre-locking position can be pushed onto the second housing part 2b.
  • the projection 23 rests with its step 25 on the first, front edge 26 of the window 22.
  • the step 25 is spaced from the first edge 26 of the window 22.
  • the lead-in bevel 24 of the projection 23 bears against the second, rear edge 27 of the window 22.
  • a latching is provided between the two housing parts 2a, 2b.
  • two radially extending latching lugs 28 are formed on the second housing part 2b.
  • the two locking lugs 28 are at a distance from the step 25 of the respectively associated projection 23, which is somewhat larger than the distance between the end face 20 of the connecting area 19 and the first edge 26 of the window 22 formed in the connecting area 19.
  • This section of the connecting area 19 is thus arranged and locked in the first position of the first housing part 2a between the step 25 of the projection 23 and the locking lug 28. So that a deliberate displacement of the first housing part 2a from the first position into the second position is not associated with excessive force, the locking lug 28 has a relatively low height. In particular, the height of the locking lug 28 is smaller than the height of the projection 23.
  • a second projection 31 formed in the first housing part 2a ensures that the metal part 4 is also fixed in its position when 8 tensile forces act on an electrical conductor inserted into the clamping point.
  • the projection 31 in the first housing part 2a then interacts with a rear second edge 32 of the metal part 4, so that tensile forces acting on a connected electrical conductor 8 are not transmitted to the contact point of the plug contact 12.
  • the second housing part 2b has at least one adjusting element 33 on its underside 18, which can be inserted into a corresponding recess in the printed circuit board 16.
  • the free end 34 of the adjusting element 33 is conical, which facilitates the insertion of the adjusting element 33 into the corresponding recess in the printed circuit board 16.
  • the adjusting element 33 is designed as a connecting flange 35, so that the housing 2 of the connecting terminal 1 is arranged in the connecting flange 35 by means of one Screw on the circuit board 16 can be screwed.
  • the second housing part 2b can also have individual adjusting elements and fixing elements that are separate from one another, which in turn can be connecting flanges or also locking pins.
  • an actuating push-button 36 is slidably arranged in the actuating opening 10. If the actuating push-button 36 is pushed further into the actuating opening 10 in the first housing part 2a from the first position shown in the figures, the end 37 of the actuating push-button 36 facing the clamping leg 5 deflects the clamping leg 5 against the spring force of the clamping spring 3, so that the spring-loaded clamping connection is opened. Then a previously connected electrical conductor 8 can simply be pulled out of the clamping point or a flexible conductor can be inserted into the clamping point.
  • FIG. 5 A metal part 4 and a plug contact 12 connected to it via the connection region 11 are shown, in which the configuration of the plug contact 12 differs somewhat from that in FIGS 1 to 4 shown plug contact 12 differs.
  • the contact legs 13, 14 each have only one spring tongue, while in the plug contact according to the 1 to 4 the two contact legs 13, 14 are each formed by two spring tongues which are arranged side by side.
  • connection terminal 1 Even if only one electrical connection terminal 1 is shown in the figures, to which only one electrical conductor 8 can be connected, the connection terminal 1 according to the invention is not limited to this. Rather, it is easily possible for several metal parts with several clamping springs and several plug contacts to be arranged in one housing. The individual metal parts with the respective plug contacts can then be arranged in individual chambers of the overall housing, so that the individual metallic parts are insulated from one another and arranged next to one another.
