Definitions

  • the invention relates to a conductor connection terminal for connecting electrical conductors to a busbar.
  • the conductor connection terminal has an insulating material housing with at least two conductor entry openings and a conductor connection space adjoining the conductor entry openings, a busbar and a clamping spring for a spring-loaded terminal connection.
  • the clamping spring has a clamping leg and a contact leg, which are connected to one another by a spring bow.
  • a connecting terminal for connecting at least two electrical conductors to one another is provided, the connecting terminal having at least two separate housing parts.
  • each separate housing part there is a spring-loaded terminal connection for making electrical contact with one electrical conductor in each case.
  • the housing parts are connected to one another via a connecting part.
  • the connecting part can also have a conductor stop in order to limit the insertion depth of the electrical conductors.
  • a small connecting terminal is to be specified, whereby the connecting terminal is a double terminal with two conductor entry openings and two spring-cage terminals.
  • an extended end section of the contact leg of a first and / or second clamping spring is hooked into a through opening in the busbar in order to provide a particularly compact connecting terminal.
  • the clamping leg and / or the contact leg of the clamping spring have a separating section, by means of which the conductor connection space can be divided into at least two spatially separated conductor connection chambers.
  • This provides a conductor connection terminal with which chamber separation is provided in a particularly space-saving and cost-effective manner, so that the electrical conductors introduced into the conductor connection terminal do not touch each other and there is therefore no impairment of the connection.
  • Neither rigid electrical conductors nor stranded conductors get into a conductor connection chamber assigned to another electrical conductor, but are reliably spatially separated from further conductor connection chambers by the separating section without the need for a separation by a separate partition provided for this purpose.
  • Each electrical conductor is thus assigned its own conductor connection chamber, in that at least one separating section creates a chamber delimitation by means of a clamping and / or contact leg of the clamping spring, which divides the common connection area.
  • the number of connectable electrical conductors, the conductor entry openings and the corresponding conductor connection chambers is not limited, but rather is variable per conductor connection terminal and can be two, three or more.
  • further clamping springs can be provided, which optionally also have a clamping and / or contact leg with a separating section.
  • the term “separating section” is understood to mean a component of the leg which is formed in one piece with the clamping leg and / or contact leg. This is a region of the leg over a predefined length in the main or longitudinal direction of the leg, which has an effect that divides the connection space into chambers.
  • the separating section is formed by an additional component and, for example, can be assembled and disassembled as required as a leg attachment.
  • the direction of extent of the separating section deviates from the main direction of extent of the clamping leg or contact leg having the separating section.
  • the main direction of extent can be, for example, the direction in which the clamping or contact leg protrudes from the spring arch into the conductor connection space.
  • the separating section can be bent laterally, upwards or downwards from the area of the clamping or contact leg adjoining the separating section in the direction of the spring arch.
  • an obtuse angle but in principle also an acute angle, can be included between the separating section and the area of the clamping or abutment leg adjoining the separating section in the direction of the spring arch.
  • the clamping leg also has, for example, a clamping section for forming a clamping point at which an inserted electrical conductor is pressed against the busbar by the spring force of the clamping spring.
  • the contact leg also has, for example, a contact section via which the clamping spring is supported on an adjacent or surrounding component.
  • the clamping spring does not necessarily have to be supported on a surrounding insulating material housing, but can in principle also be constructed in a self-supporting manner.
  • the separating section can be spatially delimited from the clamping section or contact section, in particular at a distance.
  • the direction of extension of the separating section is selected depending on the further component geometry of the conductor connection terminal so that a reliable chamber separation in the sense of a sufficient spatial delimitation of at least two conductor connections of the conductor connection terminal is achieved.
  • the separating section runs essentially perpendicularly in relation to a conductor insertion direction or, based on the main extension direction, a conductor insertion opening.
  • the separating section is provided, starting from the spring bow in the direction of the free end of the contact leg and / or clamping leg, behind a clamping point formed between the clamping spring and an inserted electrical conductor.
  • the chamber separation by the separating section is thus provided for a region of the clamping spring facing away from the spring arch and is spatially spaced from the clamping point. This reduces the risk of mutual interference between the separating section and the clamping point.
  • the separating section terminates with the free end of the clamping leg or contact leg having the separating section.
  • the separating section thus forms the end area of the clamping or contact leg opposite the spring arch.
  • the separating section is thus formed as far as possible from the clamping point and thereby increases the chamber size of the conductor connection which has the clamping spring with the separating section. In addition, mutual interference between the separating section and the clamping point is prevented.
  • the separating section forms a stop for an electrical conductor introduced into the conductor connection terminal.
  • the separating section thus limits the insertion depth of the inserted electrical conductor and prevents accidental insertion of the electrical conductor or a part thereof into an adjacent or opposite conductor connection chamber.
  • the stop can act simultaneously from several sides, for example for two electrical conductors introduced from opposite sides.
  • the separating section thus forms a stop for at least two electrical conductors introduced into the conductor connection terminal from different directions. This significantly reduces the installation space required for the components of the conductor connection terminal. The attack prevents mutual interference between several conductors inserted into the conductor connection terminal.
  • At least one conductor connection of the conductor connection terminal is designed as a plug connection for inserting a contact pin.
  • Further conductor connections of the conductor connection terminal can be designed, for example, as spring-force terminal connections or circuit board connections.
  • the plug connection for inserting a contact pin differs, for example, from a spring-loaded terminal connection in that the plug connection does not have a clamping spring.
  • the contact pin is brought into direct contact with the busbar via the plug connection.
  • the plug connection can, for example, have latching means for optionally fixing the contact pin in the conductor connection terminal.
  • the contact leg of the clamping spring forms a stop for the inserted contact pin. This brings about a further chamber separation in that the contact leg delimits the conductor connection chamber for the contact pin. Mutual interference between the contact pin and other electrical conductors introduced into the conductor connection terminal is thus avoided. If the contact leg additionally has the separating section according to the invention, this has a multiple function, since it divides the existing conductor connection space into at least three conductor connection chambers through the separating section and as a stop for the contact pin.
  • At least two conductor connections are designed as spring-loaded terminal connections with clamping springs for connecting electrical conductors to a common busbar, the terminal points formed between the electrical conductors and the busbar being in mutually offset planes.
  • a clamping point here is a contact point or contact area in which the connected electrical conductor makes contact with the busbar, the contact at the clamping point being ensured by the spring force of the clamping leg of the clamping spring acting in the direction of the busbar.
  • installation space is optimized in that, for example, due to a structure that is not mirror-symmetrical, components of one conductor connection chamber can partially protrude into free spaces in another conductor connection chamber, provided that this does not impair the electrical conductors that have been introduced.
  • the contact leg of a first clamping spring is opposite a clamping leg of a second clamping spring and / or that the clamping leg of the first clamping spring is opposite a contact leg of a second clamping spring.
  • the clamping springs are therefore not used in an axially symmetrical orientation, but rather asymmetrically or at most in a point-symmetrical or rotationally symmetrical orientation, that is to say their orientation is rotated with respect to one another.
  • the busbar can be designed, for example, as a doubly curved component, for example approximately with an S or Z shape. This provides an embodiment that is particularly space-optimized.
  • the clamping springs can also be supported punctually or in sections on the common busbar or can be supported on this.
  • the busbar therefore has not only an electrical but also a mechanical function within the conductor connection terminal.
  • the conductor connections and / or the clamping springs of the conductor connection terminal can be arranged asymmetrically to one another in order to improve the utilization of the installation space.
  • the contact leg of at least one clamping spring is mounted on the busbar and, starting from the spring arch, behind the support of the contact leg on the busbar, has an elastic, deflectable spring section with a ramp to guide the conductor to be connected.
  • the conductor connection terminal has a trigger or actuating lever, by means of which at least one clamping leg of a clamping spring can be displaced from an open position into a closed position and / or vice versa.
  • This provides a simplified actuation of at least one spring-loaded terminal connection.
  • the chamber separation which is also present, reliably prevents another electrical conductor introduced into the conductor connection terminal, which is not assigned to the lever-operated spring-force terminal connection, from reaching the pivoting or actuating area of the actuating lever.
  • FIG. 1 shows a conductor connection terminal 1 according to an advantageous embodiment of the invention.
  • the conductor connection terminal 1 has two spring-loaded terminal connections through which two electrical conductors 2a, 2b introduced into the conductor connection terminal 1 from opposite directions contact a common busbar 3.
  • the conductor connection terminal 1 has two clamping springs 4a, 4b, each with a clamping leg 5a, 5b and a respective contact leg 6a, 6b, which are connected to one another via a spring bow 7a, 7b.
  • the clamping legs 5a, 5b press the respectively inserted electrical conductor 2a, 2b against the busbar 3 with spring force and in this way ensure reliable contact between the conductor 2a, 2b and the busbar 3.
  • the main contact point between the conductor 2a, 2b and the busbar 3 is referred to as the clamping point 8a, 8b.
  • the clamping spring 4a has a separating section 9a on its contact leg 6a and the clamping spring 4b has a separating section 9b on its contact leg 6b.
  • the connection space adjoining the conductor entry openings 11a, 11b provided for the introduction of the electrical conductors 2a, 2b is converted into a plurality of spatially separated conductor connection chambers (cf. Figures 2 and 3 ) divided and thus provided a chamber separation.
  • the separating sections 9a, 9b ensure that the electrical conductors 2a, 2b do not get into the opposite connection area and do not interfere with one another.
  • the separating section 9a, 9b is provided starting from the spring bow 7a, 7b in the direction of the free end of the contact leg 6a, 6b behind the clamping point 8a, 8b.
  • the separating sections 9a, 9b are each designed as a stop for the electrical conductor 2a, 2b and terminate with the free end of the respective contact leg 6a, 6b.
  • the separating sections 9a, 9b are bent at a predefined distance from the spring bow 7a, 7b of the contact leg 6a, 6b, so that the direction of extension of the separating section 9a, 9b from the main direction of extension of the contact leg 6a, 6b having the separating section 9a, 9b deviates, and extend essentially perpendicularly to the conductor insertion direction.
  • the separating section 9a, 9b does not have to be arranged at the end of the contact leg, but can be followed by further sections, for example a further bent area for guiding the electrical conductor 2a, 2b. Furthermore, the separating section 9a, 9b does not have to be bent upwards, as shown in the figures, but can also form a chamber delimitation as a projection protruding laterally from the contact or clamping leg.
  • the conductor connection terminal 1 has an insulating material housing 10 which protects the components of the conductor connection terminal 1 from external physical and chemical influences and consists of an electrically insulating material such as plastic.
  • the insulating material housing 22 almost completely surrounds the conductor connection terminal 1, but contains at least conductor insertion openings 11a, 11b for inserting electrical conductors 2a, 2b into the conductor connection terminal 1.
  • the in Figure 1 Wire connection terminal 1 shown push button 12a.
  • the clamping legs 5a, 5b can be shifted manually in the direction of the contact legs 6a, 6b in order to more easily insert or loosen the conductor 2a, 2b and in particular multi-wire conductors 2a, 2b and between the clamping leg 5a, 5b and the busbar 3 to be able to position.
  • the contact limb 6a, 6b is mounted on the busbar 3 on a support 15 so that the contact limb 6a, 6b is supported against the busbar 3.
  • the busbar 3 has a recess on each connection side through which the contact leg 6a, 6b is guided.
  • an elastic, deflectable spring section 14 extends with a run-on slope for guiding the conductor 2a, 2b. Due to the elasticity of the spring section 14, when a conductor 2a, 2b is inserted, it is displaced as a function of the conductor diameter and thus adapts to different conductor cross-sections.
  • Figure 2 shows a conductor connection terminal 1 designed as a double connection according to a further embodiment.
  • a clamping spring 4b is used on one side of the conductor connection terminal 1.
  • Another clamping spring not shown, can be used on the opposite side of the conductor connection terminal 1.
  • Two conductor connections are designed as spring-loaded terminals with clamping springs 4b for connecting electrical conductors 2a, 2b to a common busbar 3, the terminal points formed between the electrical conductors and busbar 3 being in mutually offset planes.
  • the contact leg 6b of the clamping spring 4b merges towards the free end into a separating section 9b that is clearly bent inward, the clamping leg 5b of the clamping spring 4b is also clearly bent inwards in the transition from the clamping point to the free end.
  • the conductor connection terminal 1 has an actuation lever 12b.
  • the clamping spring 4b has a separating section 9b in order to enable a chamber to be separated.
  • the separating section 9b clearly delimits a conductor connection chamber 13b and would already be sufficient to define an additional conductor connection chamber for an electrical conductor 2a inserted into the conductor entry opening 11a on the side facing away from the conductor connection chamber 13b. It would also be conceivable here for the separating section 9b to form a stop for at least two electrical conductors 2a, 2b introduced into the conductor connection terminal 1 from different directions.
  • the embodiment shown is additionally brought about by the geometric shape of the busbar 3, in that the busbar 3 consists essentially of two horizontal main sections and one vertical main section, which are arranged in a mirror-inverted z-shape.
  • the vertical main section of the busbar 3, which connects the two horizontal main sections of the busbar 3, forms a chamber delimitation for the conductor connection chamber 13a.
  • a vertical secondary section of the busbar 3 can be provided, which extends, for example, in the direction of the contact leg 6b of the clamping spring 6b and forms a support 15 for the contact leg 6b by means of an opening in the vertical auxiliary section.
  • Figure 3 shows an embodiment of the conductor connection terminal 1 as a triple connection. While the conductor connection terminal 1 of the Figure 1 has an essentially axially symmetrical mirrored structure, the component arrangement is in Figure 3 designed asymmetrically with clamping springs 4a, 4b rotated with respect to one another and clamping points or conductor entry openings 11a, 11b offset in the plane. In this way, the available installation space of the conductor connection terminal 1 is used particularly efficiently.
  • two conductor connections are designed as spring-loaded terminals with clamping springs 4a, 4b for connecting electrical conductors 2a, 2b to a common busbar 3, the clamping points formed between the electrical conductors and busbar 3 being in mutually offset planes.
  • the contact leg 6a of one clamping spring 4a lies opposite a clamping leg 6b of the other clamping spring 4b and vice versa.
  • the components shown for the conductor connection terminal 1 differ from those shown in Figure 1 shown components as well as each other in addition in their geometric design.
  • the clamping springs 4a, 4b are basically V-springs
  • the clamping legs 5a, 5b and the contact legs 6a, 6b are each individually shaped.
  • the contact leg 6a of the clamping spring 4a is bent slightly outwards at its free end, the clamping leg 5a of the clamping spring 4a is bent slightly inwards at its free end.
  • the contact leg 6b of the clamping spring 4b merges towards the free end into a separating section 9b that is clearly bent inward, the clamping leg 5b of the clamping spring 4b is also clearly bent inwards in the transition from the clamping point to the free end. This is intended to make it clear that clamping springs 4a, 4b with different geometrical shapes can be used in the conductor connection terminal 1, so that these individual requirements for the connections to be provided are met.
  • the conductor connection terminal 1 has an actuation lever 12b through which, for example, in the in Figure 3
  • the clamping legs 5a of the clamping spring 4a can be displaced from an open position into a closed position and / or vice versa.
  • the spring-loaded terminal connection can be opened or closed with little manual force, and the position of the Clamping leg 5a of the clamping spring 4a can be seen from the outside based on the position of the actuating lever 12b.
  • the conductor connection terminal 1 shown corresponds to the structure of the in Figure 2 shown conductor connection terminal 1 partially coincide.
  • a third conductor insertion opening 11c is additionally provided, which is designed as a plug connection for inserting a contact pin (not shown).
  • the contact pin comes into direct contact with the busbar 3 when it is inserted, without being acted upon by additional spring force of a clamping spring.
  • the contact limb 6b of the clamping spring 4b forms a stop for the contact pin, so that the contact limb 6b represents a limitation for a further conductor connection chamber 13c and thus a component of the clamping spring 4b also serves to separate the chambers.
  • this further conductor connection as a printed circuit board connection or to provide other or further conductor connections on the conductor connection terminal 1.
  • the clamping springs 4a, 4b are supported punctually or in sections on the common busbar 3 or are supported on this.
  • the busbar 3 therefore has not only an electrical but also a mechanical function within the conductor connection terminal 1.
