Technical Field

The invention relates to a connecting terminal for connecting electrical conductors, comprising a housing, a current bar arranged in the housing, a clamping spring arranged in the housing for clamping a conductor to be connected against the current bar in a conductor connection chamber formed between the current bar and the clamping spring, and an actuating element mounted on the housing in a movable manner, wherein a clamping leg of the clamping spring can be actuated by means of the actuating element in order to move the clamping leg from a clamping position into an open position.

Background

The actuating element of such a connection terminal is therefore used, on the one hand, to actuate the clamping spring in order to release the conductor connection chamber for inserting the conductor to be connected. On the other hand, it can be provided that the actuating element defines the conductor connection chamber at least in sections. For both functions, it is important that the actuating element reliably assumes its predefined position not only in the clamped position but also in the open position.

If the actuating element is partially deformed or deflected out of its predefined position, for example, by excessive force in the open position, an undesired gap may be created between the housing and the actuating element in this way, into which the conductor ends of the conductors to be connected may be unintentionally introduced, so that in the clamped position no electrically conductive contact may be produced between the current bars and the electrical conductors to be connected.

Furthermore, such a deformation or deflection of the actuating element may result in the actuating element sliding off the clamping leg of the clamping spring, so that the actuating element no longer engages the clamping leg of the clamping spring. In addition to possible damage to the clamping spring and/or the actuating element, it may also be possible here for the clamping leg to spring back into the clamping position before the electrical conductor to be connected is inserted, so that the conductor can no longer be inserted into the conductor connection chamber.

Disclosure of Invention

The object of the invention is therefore to provide a connection terminal and an electronic device which enable a reliable actuation of the clamping leg by means of the actuating element.

According to the invention, this object is achieved by the features of the independent claims. Advantageous embodiments and advantageous developments of the invention are given in the dependent claims.

According to the invention, a connection terminal for connecting electrical conductors is provided, comprising a housing, a current strip arranged in the housing, a clamping spring arranged in the housing for clamping a conductor to be connected against the current strip in a conductor connection chamber formed between the current strip and the clamping spring, and an actuating element which is mounted in the housing in a movable manner, wherein a clamping leg of the clamping spring can be actuated by means of the actuating element in order to transfer the clamping leg from a clamping position into an open position. A guide element for supporting the actuating element and/or a guide element for supporting a clamping spring, against which the conductor is clamped, is arranged below a section of the current bar, viewed in the actuating direction of the actuating element.

The guide element for supporting the actuating element ensures that the actuating element is not deformed or deflected during the transition from the clamping position into the open position and vice versa and reliably remains in contact with the clamping leg of the clamping spring. The guide element for supporting the clamping spring ensures that the clamping spring is not deformed or deflected, in particular during actuation of the clamping spring by means of the actuating element, and is reliably held in the desired position inside the housing. The connection terminal may have a guide element for supporting the actuating element and a guide element for supporting the clamping spring. However, it is also possible for the connection terminal to have only one of the two guide elements.

It can be provided that the actuating element defines the conductor connection chamber at least in sections, in particular at least on both sides. In this case, it is additionally ensured by the guide element for supporting the actuating element that no play is produced between the actuating element and the housing as a result of deformation or deflection of the actuating element, which could lead to incorrect installation of the electrical conductors to be connected.

The guide element for supporting the actuating element and/or the guide element for supporting the clamping spring can be an integrated component of the housing. In this way, the individual guide elements can be integrated into the shape of the housing at low cost.

For example, it can be provided that the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring and/or the housing have or can be made of an electrically insulating plastic.

The guide element for supporting the actuating element and/or the guide element for supporting the clamping spring can be, for example, part of a side wall of the housing of the terminal. The guide element can thus be compactly integrated into the housing of the connection terminal.

Alternatively, it can be provided that the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring are provided as separate components and are connected to the housing of the connection terminal. The guide element for supporting the actuating element and/or the guide element for supporting the clamping spring can be encapsulated by the plastic injection molding of the housing, so that a positive connection can be produced between the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring and the housing of the terminal. It can be provided that the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring is detachably connected to the housing of the terminal.

The guide element for supporting the actuating element may be a web, which encloses a section of the actuating element. The actuating element can thus be prevented from being deflected by the web in a form-fitting manner.

The guide element for supporting the clamping spring can also be a web which laterally supports the section of the retaining leg of the clamping spring. The guide element for supporting the clamping spring can prevent a lateral movement of the holding leg of the clamping spring, in particular, when the clamping leg of the clamping spring is moved into the clamping position and into the open position. Even in the clamped state of the conductor, a secure fit of the clamping spring can be ensured by means of the guide element and thus tilting of the clamping spring is prevented.

In particular, it can be provided that the guide element for supporting the actuating element is part of a linear guide device which only effects a purely translational movement of the actuating element from the first position to the second position, so that the linear guide device can occupy three rotational degrees of freedom and two translational degrees of freedom for the actuating element. Such a linear guide can be preset, for example, by the geometry of the housing of the terminal, in which the actuating element is accommodated, in a purely positive manner. The housing may thus have, for example, a shaft along which the actuating element can be moved, wherein a guide element for supporting the actuating element can be used as an additional support for resisting a deflection or deformation of the actuating element.

The guide element for supporting the operating element may have a first guide surface which causes a support of the operating element against a lateral movement in the first direction. The guide element for supporting the operating element may have a second guide surface which causes a support of the operating element against a lateral movement in a second direction, which is different from the first direction. If a transverse displacement is mentioned here, this is particularly a displacement transverse to the actuating direction of the actuating element, along which the actuating element executes a translational movement in order to move the clamping leg from its clamping position into its open position and vice versa.

The first guide surface may be a planar surface. The second guide surface may be a flat surface.

The first direction may be oriented perpendicular to the actuation direction of the actuation element. The second direction may be oriented perpendicular to the actuation direction of the actuation element. Alternatively or additionally, the first direction may be oriented perpendicular to the second direction.

The actuating element can have at least one actuating arm, wherein the at least one actuating arm can define a conductor connection chamber transversely to the insertion direction of the conductor, wherein the actuating arm can rest with the actuating surface on a clamping leg of the clamping spring in the open position of the clamping spring. Depending on the installation position of the connection terminal, it can be provided that the actuating arm can also rest with its clamping surface on the clamping leg of the clamping spring in the clamping position.

The guide element for supporting the actuating element can be designed to prevent a deflection of the actuating arm transversely to the actuating direction of the actuating element and transversely to the insertion direction of the conductors to be connected. It may be provided that at least one guide surface of a guide element for supporting the actuating element is provided, along which guide surface the actuating element slides when the clamping leg is actuated, the surface normal of which guide surface may be oriented substantially perpendicularly to the actuating direction and/or perpendicularly to the insertion direction.

The at least one actuating arm may have at least one guide tab which may be arranged on the side of the actuating arm facing away from the conductor connection chamber and/or which may slide along a guide element for supporting the actuating element when the actuating element is actuated. The guide tab can be used for a defined abutment of the actuating arm on the guide element.

It can be provided that the actuating arm has two guide webs spaced apart from one another, which are provided for abutment against guide elements for supporting the actuating element and/or against sections of the housing. In particular, the guide tabs may extend substantially parallel to each other. An additional web may be provided between the guide webs or a plurality of additional webs may be provided in order to provide structural reinforcement of the actuating arm.

The at least one actuating arm may have a stop section for limiting the travel displacement of the actuating element. In particular, it can be provided that a sliding surface is provided on a recess of the actuating arm, along which the section of the clamping leg slides on the actuating arm during actuation of the clamping leg, the recess being delimited at least in sections by the stop section. In particular, the stop section may be a hook-shaped end section of the actuating arm.

The current bar can pass through the actuating element, wherein a section of the current bar can be arranged between at least one actuating arm and a second actuating arm of the actuating element, against which section the conductor is clamped by means of a clamping spring. In this way, the current bar can be compactly integrated with the actuating element into the housing of the connection terminal. The current bar may have a recess against which the actuating arm of the actuating element can rest, so that the current bar can also provide guidance of the actuating element.

The actuating element may have an asymmetrical shape, wherein the shape of at least one actuating arm differs from the shape of the second actuating arm.

It may be provided that at least one actuating arm has a length measured in the actuating direction of the actuating element which is smaller than a length of a second actuating arm measured in the actuating direction of the actuating element. For example, the second actuating arm may have a stop in order to preset a defined maximum travel length, while at least one actuating arm does not have such a stop and is thus shaped in a retracted manner relative to the second actuating arm.

Furthermore, it can be provided that at least one actuating arm has a guide tab as described above, while the second actuating arm does not have such a guide tab.

The clamping leg of the clamping spring can have at least one slide plate which is in contact with the actuating element during the transfer of the clamping leg from the clamping position into the open position.

The clamping spring can have a second slide which is in contact with the actuating element during the movement of the clamping leg from the clamping position into the open position.

Such a slide plate can correspond to a control surface or pressure surface of the control arm of the control element, along which the slide plate slides during the transfer of the clamping leg from the clamping position into the open position.

The slide plate and/or the pressing surface can be embodied at least in sections in an arcuate manner in order to facilitate a smooth sliding movement.

The slide plate can be a freely projecting end section of the clamping leg, which is arranged adjacent to or adjacent to a freely projecting contact section of the clamping leg, wherein the contact section is provided for abutment against the electrical conductor to be connected.

The connection terminals may be connection bars, which may be snapped onto the support rail.

According to the invention, an electronic device is also provided, which has one or more terminals, wherein the terminals are configured and expanded as described above.

Detailed Description

Fig. 1a shows a connection terminal 100 for connecting an electrical conductor 200. Such an electrical conductor 200 is schematically shown in a cross-section A-A according to fig. 1 b.

The connection terminal 100 according to fig. 1a has a housing 110. The current bar 120 is disposed in the housing 110. Further, a clamping spring 130 is arranged in the housing 110. The clamping spring 130 is used to clamp the conductor 200 to be connected against the current bar 120.

Between the current bar 120 and the clamping spring 130, a conductor connection chamber 140 is formed, in the region of which the conductor 200 to be connected is clamped against the current bar 120.

The connection terminal 100 has an actuating element 150 which is mounted on the housing 110 in a movable manner.

The clamping spring 130 has clamping legs 131. The actuating element 150 is provided for transferring the clamping leg 131 from the clamping position (fig. 1a, 1 b) into the open position (fig. 1c, 1 d). In other words, the clamping leg 131 of the clamping spring 130 can be actuated by means of the actuating element 150 in order to transfer the clamping leg 131 from the clamping position into the open position.

A guide element 111 for supporting the actuating element 150 is arranged below a section 121 of the current bar 120, to which section the conductor 200 is clamped by means of the clamping spring 130, viewed in the actuating direction H of the actuating element 150.

The guide element 111 is an integrated component of the housing 110.

As can be seen in the section A-A of fig. 1b, the guide element 111 is here a tab 111, which encloses the section 151 of the actuating element 150.

The guide element 111 has a first guide surface 112, which first guide surface 112 serves to support the operating element 150 against a lateral movement along the first direction R1 relative to the operating direction H of the operating element 150. The guide element 111 has a second guide surface 113, which second guide surface 113 serves to support the handling element 150 against lateral movement relative to the handling direction H in a second direction R2 different from the first direction R1. The web 111 thus resists a displacement of the actuating element 150 transversely to the actuating direction H in a form-locking manner.

The first direction R1 is oriented perpendicular to the actuating direction H of the actuating element 150. The second direction R2 is oriented perpendicular to the actuating direction H of the actuating element 150. The first direction R1 is oriented perpendicular to the second direction R2.

The actuating element 150 has an actuating arm 152, wherein the actuating arm 152 delimits the conductor junction chamber 140 transversely to the insertion direction E of the conductor 200, and wherein the actuating arm 152 rests with an actuating surface 154 on the clamping leg 131 of the clamping spring 130 in the open position of the clamping spring 130.

The actuating arm 152 has a guide tab 156 which is arranged on the side of the actuating arm 152 facing away from the conductor junction housing 140 and slides along the guide element 111 when the actuating element 150 is actuated. The actuating arm 152 has two

further webs

157, 158 for stiffening and guiding the actuating element 150.

The actuating element 150 has a second actuating arm 153 with a stop section 159 for limiting a travel displacement of the actuating element 150 in the actuating direction H.

The actuating element 150 has an asymmetrical shape, wherein the shape of the actuating arm 152 differs from the shape of the second actuating arm 153. The actuating arm 152 is shorter than the actuating arm 153, as seen in the actuating direction H, since the actuating arm 153 has a stop 159.

The actuating element 150 has a further actuating surface 160 in the region of the second actuating arm 153, as can be seen in fig. 2. The control surface 154 of the actuating arm 152 and the control surface 160 of the second actuating arm 153 are each formed in a curved manner. A recess 161 is formed between the stop 159 of the second lever arm 153 and the lever face 160.

Fig. 3 shows a separate view of the clamping spring 130.

The clamping leg 131 of the clamping spring 130 has a first slide 132 which is in contact with the actuating element 150 during the transfer of the clamping leg 131 from the clamping position into the open position.

The clamping leg 131 of the clamping spring 130 has a second slide 133 which is in contact with the actuating element 150 during the transfer of the clamping leg 131 from the clamping position into the open position.

The first slide 132 corresponds to a control surface 154 or a pressure surface 154 of the control arm 152 of the control element 150, along which the slide 132 slides during the transfer of the clamping leg 131 from the clamping position into the open position, and vice versa.

The slide plate 132 and the pressing surface 154 are at least partially curved or bent in order to facilitate a smooth sliding movement.

The second slide 133 corresponds to a control surface 160 or a pressing surface 160 of the control arm 153 of the control element 150, along which the slide 133 slides during the transfer of the clamping leg 131 from the clamping position into the open position and vice versa.

The slide 133 and the pressure surface 160 are at least partially curved or bent in order to facilitate a smooth sliding movement.

The sliding

plates

132, 133 are each freely projecting end sections of the clamping leg 131. The sliding

plates

132, 133 are arranged adjacent or next to the freely projecting contact sections 134 of the clamping legs 131, wherein the contact sections 134 are provided for abutment against the electrical conductors 200 to be connected.

The clamping spring 130 has

recesses

137, 138 on a support leg 136 which is connected to the clamping leg 131 by an arcuate section 135, in order to provide free space for accommodating the

slide plates

132, 133 in the open position.

Fig. 4 shows an isolated view of the current bar 120. The current bar 120 has

recesses

122, 123 against which the actuating

arms

152, 153 of the actuating element 150 can rest, so that the current bar 120 also provides a guide for the actuating element 150.

As can be seen in fig. 5, the current bar 120 passes through the actuating element 150, wherein the section 121 of the current bar 120 is arranged between the actuating arm 152 and the second actuating arm 153 of the actuating element 50.

Fig. 6 shows an isolated view of the housing 110. The housing 110 here has an insulating plastic.

The housing 110 has a hoistway 114 along which the steering element 150 is movable. The well 114 has a recess 115 into which the tab 162 of the operating element 150 engages in order to provide for a positionally correct installation.

The guide element 111 and the shaft 114 form a linear guide for the actuating element 150, which allows only a purely translational movement of the actuating element 152 along the actuating direction H from the first position (fig. 1a, 1 b) into the second position (fig. 1a, 1 b), so that the linear guide occupies three rotational and two translational degrees of freedom for the actuating element 150. The guide element 111 serves in particular as an additional support for deflection or deformation of the actuating arm 152 in order to prevent the actuating arm 152 from sliding off the slide 132.

The housing 110 also has tabs 116 for receiving the clamping springs 130. The housing has a recess for receiving the current bar 120.

To sandwich the conductor 200 between the clamping spring 130 and the current bar 120, the actuating element 150 is first moved translationally from the position shown in fig. 1a to the position shown in fig. 1c along the actuating direction H. The clamping spring 130 is compressed in this way, wherein the clamping leg 131 approaches the support leg 136.

During this pushing movement, the

slide plates

132, 133 slide along the actuating surfaces 154, 160 of the actuating

arms

152, 153 of the actuating element 150.

The actuating arm 152 is guided with its guide tab 156 along the guide element 111 of the housing 110. The guide element 111 prevents the actuating arm 152 from being deflected in a direction R2 transverse to the actuating direction H and reliably remains engaged with the slide 132 of the clamping spring 130. The guide element 111 thus effects a guide of the actuating arm 152 in the region below the section 121 of the current bar 120, viewed in the actuating direction H.

Once the clamping legs 131 of the clamping spring 130 are in the open position shown in fig. 1c and 1d, the conductor connection chamber 140 is released for inserting the conductor 200 into the conductor connection chamber 140 along the insertion direction E, and the conductor 200 can be moved between the clamping legs 131 and the current bar 120.

The actuating element 150 is then released and, as a result of the stress of the clamping spring 130, is moved under spring loading by the clamping leg 131 against the actuating direction H until the clamping leg 131 with its contact section 134 bears against the conductor 200 introduced into the conductor connection chamber 140 and presses the conductor 200 against the section 121 of the current bar 120. In this state, the conductor 200 is clamped between the clamping spring 130 and the current bar 120, wherein the spring force of the clamping spring 130 acting on the conductor 200 fixes the position of the conductor 200.

To release the conductor 200 again from the connection terminal 100, the actuating element 150 can be moved again in the actuating direction H in order to lift the contact section 134 of the clamping spring 130 from the conductor 200 and release the same.

Movement of the actuating element 150 against the spring force of the clamping spring 130 can be effected manually, for example, by means of a tool, such as a screwdriver or the like. Alternatively, it may be provided that the handling element 150 is mechanically handled to allow automatic installation of the conductor 200.

Fig. 7 shows a further embodiment of the connection terminal 100, which in addition to the embodiment of the connection terminal 100 shown in fig. 1 to 6 has a guide element 162 for supporting the clamping spring 130. By means of this guide element 162, the clamping spring 130 can be prevented from tipping or slipping sideways from the housing 110.

The guide element 162 for supporting the clamping spring 130 is here likewise formed integrally with the housing 110 and thus in one piece, as is the guide element 111 for supporting the actuating element 150. The guide member 162 is formed on a sidewall 164 of the housing 110. Thus, the guide element 162 forms an extension of the side wall 164. Thus, both the guide element 111 for supporting the actuating element 150 and the guide element 162 for supporting the clamping spring 130 are formed on the side wall 164 of the housing 110. The guide element 111 for supporting the actuating element 150 also forms an extension of the side wall 164.

The guide element 162 is constructed in the form of a tab. The guide element 162 extends here in the direction of the guide connection chamber 140 opposite to the actuating direction H of the actuating element 150. The guide element 162 for supporting the clamping spring 130 thus extends from the side wall 164 of the housing 110, proceeding from the side wall 164 of the housing, transversely to the direction of extension of the guide element 111 for supporting the actuating element 150, in the direction of the guide connection chamber 140.

The guide element 111 for supporting the actuating element 150 and/or the guide element 162 for supporting the clamping spring 130 can also each be formed by two webs extending parallel to one another, which are not shown here, so that a support of both sides of the actuating element 150 and/or the clamping spring 130 can be achieved. The two webs of the guide element 111 and/or the two webs of the guide element 162 are then formed on two side walls 164 of the housing 110 which extend parallel to one another. Thus, lateral tilting of the actuating element 150 and/or the clamping spring can be prevented on both sides.

The guide element 162 extends in the direction of the guide connection chamber 140 in such a way that the guide element 162 laterally overlaps the retaining leg 163 of the clamping spring 130. The guide element 162 thus forms a lateral support surface for the retaining leg 163 of the clamping spring 130. The guide element 162 passes over a longitudinal side edge 165 of the retaining leg 163.

The guide element 162 for supporting the clamping spring 130 is likewise formed under the section 121 of the current bar 120, as is the guide element 111, viewed in the actuating direction H of the actuating element 150, with respect to which section the conductor 200 is clamped by the clamping spring 130.
