Definitions

  • the invention relates to a conductor connection terminal according to the preamble of claim 1.
  • a connecting terminal for connecting at least two electrical conductors to one another, the connecting terminal having at least two separate housing parts.
  • each separate housing part there is a spring-loaded terminal connection for electrically contacting one electrical conductor each.
  • the housing parts are connected to one another via a connecting part.
  • the connecting part can also have a conductor stop to limit the insertion depth of the electrical conductors.
  • connection terminal is a double terminal with two conductor insertion openings and two spring-loaded terminal connections.
  • connection terminal is a double terminal with two conductor insertion openings and two spring-loaded terminal connections.
  • an extended end section of the contact leg of a first and/or second clamping spring is hooked into a through-opening of the busbar in order to provide a particularly compact connection terminal.
  • Additional conductor terminals are available from the DE 20 2017 105 467 U1 , which discloses a conductor connection terminal according to the preamble of claim 1, and the JP H09 147931 A known.
  • the contact leg of the clamping spring has a separating section by means of which the conductor connection space can be divided into at least two spatially separate conductor connection chambers.
  • This provides a conductor connection terminal with which a chamber separation is provided in a particularly space-saving and cost-effective manner, so that the electrical conductors inserted into the conductor connection terminal do not touch one another and thus the connection is not impaired.
  • rigid electrical conductors nor stranded conductors enter a conductor connection chamber assigned to another electrical conductor, but are reliably spatially separated from other conductor connection chambers by the separating section, without the need for separation by a separate partition wall provided for this purpose.
  • Each electrical conductor is thus assigned its own conductor connection chamber, with at least one separating section creating a chamber boundary by means of a clamping and/or contact leg of the clamping spring, which divides the common connection space.
  • the number of connectable electrical conductors, conductor insertion openings and corresponding conductor connection chambers is not limited, but is variable per conductor connection terminal and can easily be two, three or more. For example, even if several spring-loaded terminals are provided per conductor connection terminal, additional clamping springs can be provided, which optionally also have a clamping and/or contact leg with a separating section.
  • the term "separating section" refers to a component of the leg that is formed in one piece with the clamping and/or contact leg. It is an area of the leg over a predefined length in the main or longitudinal direction of the leg, which has the effect of dividing the connection space into chambers.
  • the separating section is formed by an additional component and can be assembled and disassembled as required, for example as a leg attachment.
  • the direction of extension of the separating section deviates from the main direction of extension of the clamping leg or contact leg having the separating section.
  • the main direction of extension can be, for example, the direction in which the clamping or contact leg extends 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 that adjoins 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 contact leg that adjoins the separating section in the direction of the spring arch.
  • the change in direction defines the different areas of the clamping and/or contact leg from one another.
  • 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 for example, has an additional 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 housing, but can in principle also be self-supporting.
  • the separating section can be spatially separated from the clamping section or contact section, in particular spaced apart.
  • the extension direction of the separating section is selected depending on the further component geometry of the conductor connection terminal so that a reliable chamber separation is achieved in the sense of a sufficient spatial delimitation of at least two conductor connections of the conductor connection terminal.
  • the separating section runs essentially perpendicular to a conductor insertion direction or related to the main extension direction of a conductor insertion opening.
  • the separating section is provided starting from the spring arch in the direction of the free end of the contact 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 an area of the clamping spring facing away from the spring arch and is spatially distanced from the clamping point. This reduces the risk of mutual interference between the separating section and the clamping point.
  • the separating section ends at the free end of the contact leg having the separating section.
  • the separating section thus forms the end region of the contact leg opposite the spring arch.
  • the separating section is thus formed as far away 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 inserted into the conductor connection terminal.
  • the separating section thus limits the insertion depth of the inserted electrical conductor and prevents the accidental insertion of the electrical conductor or a part thereof into an adjacent or opposite conductor connection chamber.
  • the stop can be effective from several sides at the same time, for example for two electrical conductors inserted from opposite sides.
  • the separating section thus forms a stop for at least two electrical conductors inserted into the conductor connection terminal from different directions. This significantly reduces the installation space required for the components of the conductor connection terminal.
  • the stop Prevents mutual interference between multiple 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.
  • Other conductor connections of the conductor connection terminal can be designed, for example, as spring-loaded clamp connections or circuit board connections.
  • the plug connection for inserting a contact pin differs from a spring-loaded clamp connection, for example, 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 have, for example, locking 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 results in a further separation of the chambers, as the contact leg limits the conductor connection chamber for the contact pin. This prevents mutual interference between the contact pin and other electrical conductors inserted into the conductor connection terminal. If the contact leg also has the separating section according to the invention, this has a multiple function, as 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, wherein the clamping points formed between the electrical conductors and the busbar are located in planes offset from one another.
  • a clamping point is a contact point or contact area in which the connected electrical conductor contacts the busbar, wherein the contact at the clamping point is ensured by the spring force of the clamping leg of the clamping spring acting in the direction of the busbar.
  • installation space is optimized, for example by allowing components of a conductor connection chamber to partially protrude into the free spaces of another conductor connection chamber due to a non-mirror-symmetrical structure, provided that this does not lead to interference with inserted electrical conductors.
  • 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 asymmetrically or at most in a point or rotationally symmetrical orientation, i.e. their orientation is rotated relative to one another.
  • the busbar can be designed, for example, as a double-curved component, approximately with an S or Z shape. This provides a particularly space-optimized embodiment.
  • the clamping springs can also be supported on the common busbar at certain points or in sections, or can be supported on it.
  • the busbar therefore has not only an electrical function, 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 use of installation space.
  • the contact leg of at least one clamping spring is mounted on the busbar and has an elastic, deflectable spring section with a run-on slope for guiding the conductor to be connected, starting from the spring arch behind the support of the contact leg on the busbar.
  • Conductors with a large conductor cross-section or diameter are subjected to sufficient spring force from the clamping leg and the spring section due to the deflectability of the spring section, without the conductor experiencing undesirable deformation, for example through squeezing, pressing, pushing, clamping or forcing or similar.
  • conductors with a small conductor cross-section or diameter are also contacted and clamped particularly securely due to the spring section, which in this case experiences less deflection due to the inserted conductor, and the clamping leg.
  • the conductor connection terminal has a pusher or actuating lever, by means of which at least one clamping leg of a clamping spring can be moved from an open position to a closed position and/or vice versa.
  • This provides a simplified actuation of at least one spring-force clamp connection.
  • the chamber separation that is also present reliably prevents another electrical conductor inserted into the conductor connection terminal, which is not assigned to the lever-operated spring-force clamp 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 clamp 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 contact leg 6a, 6b, which are connected to one another via a spring arch 7a, 7b.
  • the clamping legs 5a, 5b press the electrical conductor 2a, 2b introduced against the busbar 3 with spring force and in this way ensure secure 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 separating sections 9a, 9b divide the connection space adjacent to the conductor insertion openings 11a, 11b provided for the introduction of the electrical conductors 2a, 2b into several spatially separated conductor connection chambers (cf. Figures 2 and 3 ) and thus a chamber separation is provided.
  • the separating sections 9a, 9b ensure that the electrical conductors 2a, 2b do not reach the opposite connection area and do not affect each other.
  • the separating section 9a, 9b is provided starting from the spring arch 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 arch 7a, 7b from the contact leg 6a, 6b, so that the extension direction of the separating section 9a, 9b deviates from the main extension direction of the contact leg 6a, 6b having the separating section 9a, 9b, and extend essentially perpendicular 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 an area bent again 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 boundary as a projection protruding laterally from the contact or clamping leg.
  • the conductor connection terminal 1 has an insulating housing 10 which protects the components of the conductor connection terminal 1 from external physical and chemical influences and is made of an electrically insulating material such as plastic.
  • the insulating 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 conductor connection terminal 1 shown has a pusher 12a.
  • the clamping legs 5a, 5b can be manually moved in the direction of the contact legs 6a, 6b in order to be able to insert or remove the conductor 2a, 2b, and in particular multi-wire conductors 2a, 2b, more easily and to position them between the clamping leg 5a, 5b and the busbar 3.
  • the contact leg 6a, 6b is mounted on the busbar 3 on a support 15 so that the contact leg 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 with a run-on slope for guiding the conductor 2a, 2b extends from the support 15 in the direction of the separating section 9a, 9b of the contact leg 6a, 6b. Due to the elasticity of the spring section 14, it is displaced when a conductor 2a, 2b is inserted depending on 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 inserted on one side of the conductor connection terminal 1.
  • a further clamping spring not shown, can be inserted on the opposite side of the conductor connection terminal 1.
  • Two conductor connections are designed as spring-loaded terminal connections with clamping springs 4b for connecting electrical conductors 2a, 2b to a common busbar 3, with the clamping points formed between the electrical conductors and the busbar 3 lying in planes offset from one another.
  • the contact leg 6b of the clamping spring 4b merges into a separating section 9b that is bent significantly inwards towards the free end, and the clamping leg 5b of the clamping spring 4b is also bent significantly inwards in the transition from the clamping point to the free end.
  • the conductor connection terminal 1 has an actuating lever 12b to actuate at least one spring-loaded terminal connection of the conductor connection terminal 1.
  • the clamping spring 4b has a separating section 9b to enable chamber separation.
  • 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 insertion opening 11a on the side facing away from the conductor connection chamber 13b. It would also be conceivable that the separating section 9b forms a stop for at least two electrical conductors 2a, 2b inserted into the conductor connection terminal 1 from different directions.
  • the geometric shape of the busbar 3 additionally brings about a chamber separation, in that the busbar 3 essentially consists 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 boundary 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 secondary 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 a substantially axially symmetrical mirrored structure, the component arrangement in Figure 3 with clamping springs 4a, 4b rotated relative to each other and clamping points or conductor insertion 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 terminal connections with clamping springs 4a, 4b for connecting electrical conductors 2a, 2b to a common busbar 3, whereby the clamping points formed between the electrical conductors and the busbar 3 are located in planes offset from one another.
  • the contact leg 6a of one clamping spring 4a is opposite a clamping leg 6b of the other clamping spring 4b and vice versa.
  • the Figure 3 Components of the conductor terminal 1 shown differ from those in Figure 1 shown components and also among themselves 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 into a separating section 9b that is bent significantly inwards towards the free end, the clamping leg 5b of the clamping spring 4b is also bent significantly inwards at the transition from the clamping point to the free end.
  • the conductor connection terminal 1 has an actuating lever 12b, by means of which, for example, in the Figure 3
  • the clamping leg 5a of the clamping spring 4a can be moved from an open position to a closed position and/or vice versa. This allows the spring-loaded clamp connection to be opened or closed with little manual force, and the position of the Clamping leg 5a of the clamping spring 4a can be identified from the outside by the position of the operating lever 12b.
  • the conductor connection terminal 1 shown corresponds to the structure of the Figure 2 shown conductor connection terminal 1.
  • 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 without being subjected to the additional spring force of a clamping spring.
  • the contact leg 6b of the clamping spring 4b forms a stop for the contact pin, so that the contact leg 6b represents a boundary for a further conductor connection chamber 13c and thus here too a component of the clamping spring 4b serves to separate the chambers.
  • this further conductor connection as a circuit board connection or to provide other or further conductor connections on the conductor connection terminal 1.
