Description

Connecting assembly, connecting device and electronic equipment

Technical Field

The invention relates to a connection assembly for connecting electrical conductors. The invention also relates to a connecting device with at least one such connecting assembly and to an electronic device.

Background

Such a connecting assembly usually has a clamping spring in the form of a leg spring with a holding leg and a clamping leg, wherein a conductor introduced into the connecting assembly can be clamped to a busbar by means of the clamping leg of the clamping spring. If, in particular, a flexible conductor is clamped, the clamping spring must be moved into the open position by means of an actuating element before the conductor is introduced and is actuated thereby in order to pivot the clamping spring or the clamping leg away from the busbar, so that the conductor can be introduced into the intermediate space between the busbar and the clamping spring. Only in the case of a rigid and therefore stable conductor can the conductor exert sufficient force on the clamping spring or the clamping leg of the clamping spring in order to be able to deflect the clamping leg away from the busbar without the operating element having to be actuated by the user for this purpose. In the case of a flexible conductor, the user must first pivot the clamping spring away from the bus bar by operating the operating element in order to be able to insert the flexible conductor. In order to clamp the inserted conductor, the operating element must again be manually operated by the user in order to transfer the clamping spring from the open position into the clamping position. The handling of the operating element by the user makes it difficult for the user to install or connect the conductors, since the handling is cumbersome and thus also increases the time consumption.

Disclosure of Invention

It is therefore an object of the present invention to provide a connection assembly and a connection device in which the connection of, in particular, flexible conductors can be improved.

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

The connecting assembly according to the invention has: a conductor connection space; a bus bar having a bus bar section against which a conductor to be connected introduced into the conductor connecting space can be clamped; a clamping spring having clamping legs that are translatable to a clamping position and an open position; and a holding element having a holding section which, in the open position, engages with the clamping leg of the clamping spring in order to hold the clamping leg in position, wherein, for the purpose of transferring the clamping spring from the open position into the clamping position, the holding element has a pressure surface which can be operated by the conductor to be connected when the conductor is introduced into the conductor connection space, such that the holding section of the holding element can be disengaged from the clamping leg by operating the pressure surface. Furthermore, the connecting assembly has a display element for displaying the connection state of the electrical conductor.

By means of the connecting assembly according to the invention, it is now also possible to connect the flexible conductor and clamp it against the busbar section of the busbar without manual operation of the operating element. The clamping spring is preferably designed as a helical leg spring having a holding leg and a clamping leg designed to be pivotable relative to the holding leg. The holding legs are preferably arranged in a fixed position. For example, the holding leg can be fixed to the bus bar, so that the clamping spring can be held on the bus bar by its holding leg. By means of a pivoting movement of the clamping leg of the clamping spring, the clamping leg can be moved into an open position, in which the clamping leg is arranged at a distance from the bus bar section and a conductor to be connected can be introduced into or can be led out of the intermediate space formed between the bus bar section and the clamping leg, and into a clamping position, in which the clamping leg can bear against the bus bar section or against the connected conductor in order to clamp the conductor relative to the bus bar section. The connecting assembly has a holding element which engages with the clamping leg of the clamping spring in the open position of the clamping spring, so that the clamping leg of the clamping spring is held in the open position without manual assistance, so that in particular a flexible conductor can be introduced into the intermediate space formed thereby between the busbar section and the clamping spring. The intermediate space forms a conductor connection space into which a conductor to be connected can be introduced. The holding element has a fastening section, on which the clamping leg can be held in the open position, so that an undesired pivoting back of the clamping leg in the direction of the busbar section can be prevented. The holding element has a pressure surface which is arranged in alignment with the insertion region of the conductor into the connecting assembly and is therefore arranged in the extension of the conductor insertion opening, so that the conductor, when inserted into the connecting assembly, strikes the pressure surface of the holding element and thus enables the clamping leg to be released from the fastening section of the holding element. By means of this special mechanism, the connection of the flexible conductor can be realized particularly simply by a lead-in movement of the conductor, without the user having to actuate further elements on the connection assembly, for example an actuating element, in order to release the clamping spring and transfer it from the open position into the clamping position. This makes the handling of the connection assembly easy and saves time when connecting the conductors. In order to release the conductor to be connected from the clamping position again, the clamping leg of the clamping spring can be pivoted away from the busbar section by means of the actuating element until the open position is reached and the clamping leg engages with the retaining element in order to retain the clamping spring in the open position. The holding element is preferably an element or component which is designed separately from the clamping spring and the bus bar. The conductor connection space is delimited downwards in the direction of introduction of the conductor by the retaining element. The holding element preferably extends substantially transversely to the bus bar section of the bus bar.

The connecting assembly also has a display element, by means of which a user can visually recognize whether the conductor to be connected is in the correct position within the connecting assembly, so that a reliable connection can be ensured. In particular, the display element can indicate to the user whether the conductor to be connected is introduced into the conductor connection space deep enough to enable a reliable clamping. The user can visually recognize, via the display element, whether the electrical conductor introduced into the connecting assembly has been clamped against the busbar by means of the clamping spring or whether the conductor, despite having been introduced into the housing of the connecting device with the connecting assembly, has not yet been triggered by the retaining element and therefore the clamping spring has not yet reached the clamping position. Furthermore, it can also be displayed by means of a display element in which position the clamping leg of the clamping spring is in the clamping position or the open position. In this way, a user can detect a falsely triggered clamping spring, i.e. a clamping leg that has undesirably transitioned from the open position into the clamping position, from the outside by means of the display element, and can reset it or return it again by means of the operating element.

Preferably, the display element can be formed on the operating element. The connection state of the conductors and also the position of the clamping legs of the clamping spring can thus be visually displayed to the user directly by the position of the operating element. The display element may be part of the operating element. The display element can be formed on a head region of the operating element, wherein the head region can be formed on a front end of the operating element remote from the operating surface of the operating element. The display element formed on the operating element makes it possible to achieve a uniform visual feedback about the connection state of the conductors to be connected, independently of the diameter of the electrical conductor. If the display element is formed on the front end of the operating element, the display element can project from the opening of the housing in the connected state of the conductors. This makes it possible to provide the user with a clear visual feedback, in order to be able to indicate to the user whether the conductor is clamped between the clamping spring and the busbar and is therefore connected. If the conductor is not yet clamped and therefore not connected, the front end of the operating element and therefore the display element are preferably also located inside the housing and do not protrude from the opening of the housing, so that the display element is not yet visible to the user. Thereby, the connection state of the electrical conductor can be visually displayed to the user simply by the position of the display element.

Furthermore, a spring element can be provided, which can interact with the actuating element. A tensioning force can be applied to the operating element by means of the spring element. The spring element is preferably designed as a compression spring. Preferably, the spring element is formed in the form of a helical spring. In the clamping position of the clamping leg of the clamping spring, the spring element is preferably in a relaxed, triggered state, so that the operating element is moved away from the holding element via the spring element. In the open position of the clamping legs of the clamping spring, the spring element is preferably in a tensioned state. By means of the spring element, it is ensured that the actuating element and thus the display element formed on the actuating element are always positioned at the same height, in particular in the clamping position of the clamping leg of the clamping spring, regardless of the size of the cross section of the connected conductor.

The actuating element can have, for example, a recess in which the spring element is at least partially arranged.

The connecting assembly can preferably be designed such that the busbar section can be arranged between the conductor connection space and the fastening section of the holding element. In order to improve the positioning of the individual elements relative to one another and thus also to facilitate the connection of the conductors to the user, the bus bar section is arranged between the conductor connection space and the fastening section of the holding element. The bus bar section thus separates the region in which the conductor is introduced and clamped (conductor connection space) from the operating element. For actuating the clamping leg of the clamping spring, the actuating element preferably acts on an end section of the clamping leg of the clamping spring. This end section of the clamping leg preferably passes through the busbar section. The end section of the clamping leg therefore preferably leads out of the conductor connection space, so that the clamping leg extends beyond the conductor connection space. The conductor connection space preferably extends between the bearing point of the clamping spring in the region of its arc-shaped section and the bus bar section.

The holding element is preferably mounted so as to be movable in an inclined manner. By applying a pressure to the pressure surface by means of the conductor, the holding element can thereby be subjected to a pivoting or tilting movement in the direction of insertion of the conductor. By means of the pivoting movement of the holding element, the fastening section of the holding element can be disengaged from the clamping leg of the clamping spring, so that they can be released from one another without manual assistance, and the clamping leg of the clamping spring can be transferred from the open position into the clamping position without manual assistance in order to clamp a conductor inserted into the conductor connection space relative to the busbar section.

Preferably, the holding element is mounted on the busbar so as to be movable in a tilting manner. The holding element can be mounted on the bus bar in such a way that it surrounds the bus bar, in particular the bus bar section. For example, the holding element can have a window-like opening through which the bus bar can pass with its bus bar section. The bus bar section can thus spatially separate the pressure surface of the holding element from the fastening section of the holding element.

In order to be able to ensure that the clamping legs of the clamping spring are reliably held on the fastening section of the holding element in the open position, the fastening section of the holding element may preferably have a hook shape. Thereby, in the open position, the clamping leg may be hooked at the fixation section. The fastening section can have a half S-shape, for example, in order to form a hook shape.

The clamping leg of the clamping spring preferably has a through-hole for the conductor to be connected to pass through, wherein the bus bar section can pass through the through-hole. When the conductor to be connected is introduced in the introduction direction, the conductor can then be passed through the through-hole, so that the conductor passes through the through-hole of the clamping leg in the connected state. Preferably, the bus bar section with respect to which the conductor is clamped also projects through the through hole. By forming the through-opening, it is possible to achieve that the clamping leg projects beyond the busbar section and can thus be fastened with its end section outside the conductor connection space to the fastening section of the holding element. The through-opening is preferably formed in the form of a window, which is delimited by a plurality of, in particular by four, delimiting edge surfaces. The through-hole preferably has a rectangular shape.

The through-opening can have a first limiting edge surface, which can form a clamping edge for the conductor to be connected. The clamping edge for clamping the lead-in conductor to the busbar section is preferably formed not just at the free end of the clamping leg but rather in the region of a through-opening of the clamping leg, which is formed along the length of the clamping leg. The limiting edge surface forming the clamping edge preferably points in the direction of the busbar section. By clamping the conductor to be connected in the through-hole and by means of the clamping edge formed on the limiting edge surface of the through-hole, clamping against the busbar section which likewise leads through the through-hole, a particularly gas-tight clamping connection of the conductor to the busbar section can be formed and achieved.

The through-opening preferably has a second limiting edge surface which can be brought into engagement with the fastening section of the holding element in the open position. When the clamping leg is transferred from the clamping position to the open position, the clamping leg can be pivoted such that the retaining element can be passed with its fastening section through the through-opening, so that the fastening section can be hooked onto or snapped off from the rear side onto the second limiting edge face, in order to be able to hold the clamping leg in the open position. The second limiting edge surface is preferably formed opposite the first limiting edge surface. The second limiting edge surface is preferably located outside the conductor connection space. The first limiting edge surface is preferably located in the conductor connection space.

For actuating the clamping leg, the actuating element can have an actuating surface on the front end. The actuating surface can be arranged on an actuating projection formed on the front end of the actuating element. In the region of the actuating projection, the actuating element can have a smaller cross section than in the remaining region of the actuating element.

Preferably, the actuating projection can be shaped such that it can be held at the fastening section of the holding element in the open position. The actuating element can then be held together with the clamping legs in the open position on the fastening section of the holding element. The fastening projection can be formed in a curved or hook-shaped manner, so that it can hook onto the fastening section of the holding element.

The object is also achieved according to the invention by means of a connecting device having a housing and at least one connecting assembly arranged in the housing, wherein the at least one connecting assembly is constructed and improved as described above.

The connecting means may be, for example, a connecting terminal, such as a junction box or a circuit board connecting terminal. Furthermore, the connecting device can also be a plug connector. Inside the housing of the connecting device, one or more connecting assemblies according to the invention can be arranged and constructed. The display element of the connecting assembly can be positioned and guided in the housing in such a way that the connection state can be displayed to the user by the position of the display element relative to the housing. If the conductors are securely connected and the clamping legs of the clamping spring are in the clamping position, the display element can preferably at least partially protrude from the housing, so that the display element is visible to the user. If no connecting conductor is present and the clamping legs of the clamping spring are in the open position, the display element can still be inserted into the housing, for example, to such an extent that it is covered by a wall of the housing that it is not visible from the outside.

The object is also achieved according to the invention by an electronic device having at least one connecting assembly and/or at least one connecting device which are constructed and improved as described above.

Detailed Description

Fig. 1 shows a connecting device 200 with a housing 210, inside which two connecting assemblies 100 are arranged. The connecting device 200 is designed here in the form of a terminal block.

Each connecting assembly 100 is assigned a conductor insertion opening 211, through which the conductors 300 to be connected can be inserted into the housing 210 and guided to the respective connecting assembly 100, as can be seen, for example, in the connecting assembly 100 shown on the right in fig. 1. The conductor introduction opening 211 is formed on the housing 210 or in the housing 210.

Each connecting assembly 100 has a conductor connecting space 110, inside which a conductor 300 can be clamped and thus connected. The conductor 300 to be connected may be introduced into the conductor connection space 110 through the conductor introduction opening 211. The conductor connection spaces 110 are formed in alignment with the respective conductor introduction openings 211.

Furthermore, each connecting assembly 100 has a bus bar 111, wherein the bus bars 111 of two connecting assemblies 100 arranged in the housing 210 are formed integrally with one another. The bus bar 111 of each connecting assembly 100 has a bus bar section 112, with respect to which bus bar section 112 a conductor 300 to be connected, which is introduced into the conductor connection space 110, can be clamped, as can be seen, for example, in the connecting assembly 100 shown on the right in fig. 1. The busbar section 112 extends parallel to the insertion direction E in which the conductor 300 is inserted into the conductor connection space 110 or the connecting assembly 100 or the connecting device 200.

In order to clamp the conductor 300 to be connected relative to the busbar section 112, each connecting assembly 100 has a clamping spring 113.

The clamping spring 113 has a holding leg 114 and a clamping leg 115, wherein the holding leg 114 and the clamping leg 115 are connected to one another by an arc-shaped section 116.

The holding leg 114 has a fastening point, by means of which the holding leg 114 and the clamping spring 113 can be fastened to the busbar 111. The fastening point can be formed, for example, in the form of an opening into which a latching projection formed on the busbar 111 can be hooked. The retaining leg 114 is here formed in an L-shaped bent manner.

The clamping leg 115 has an end section 119 which can be engaged with a fastening section 120 of a holding element 121, so that the clamping leg 115 can be held in the open position, as can be seen, for example, in the connecting assembly 100 shown on the left in fig. 1.

As can be seen, for example, in fig. 4, a through-opening 122 is formed along the length of the clamping leg 115, said through-opening being formed in the form of a window in the clamping leg 115. The clamping spring 113 is arranged on the bus bar 111 in such a way that the bus bar section 112 extends through the through-opening 122. Thus, the clamping leg 115 may surround the busbar section 112. Furthermore, the through-opening 122 serves to receive the conductor 300 to be connected in such a way that the conductor 300 passes through the through-opening 122 during connection and the conductor 300 extends through the through-opening 122 in the connected or clamped state, as can be seen, for example, in the connecting assembly 100 of the connecting device 200 shown on the right in fig. 4.

The through-opening 122 has four bounding edge faces 123, 124, 125, 126. The first limiting edge surface 123 forms a clamping edge for the conductor 300 to be connected in that, in the clamping position, the conductor 300 guided through the through-opening 122 is clamped with respect to the busbar section 112 by means of the first limiting edge surface 123.

A second limiting edge surface 124, which is opposite the first limiting edge surface 123, is formed on the end section 119 of the clamping leg 115, which engages with the fastening section 120 of the holding element 121 in the open position. The limiting edge surface 123 can form an abutment surface for the fastening section 120 in order to engage with the clamping leg 115. The fastening portion 120 is bent in such a way that it forms a hook shape, which in the open position can likewise be guided through the through-opening 122 and thereby be hooked with the clamping leg 115 on the limiting edge surface 123 or on the end portion 119, as can be seen in the detail view of fig. 3 in particular.

The holding member 121 is supported on the bus bar 111 so as to be movable obliquely. As can be seen in fig. 3, the holding element 121 has a window-like opening 127 through which the busbar section 112 projects. The holding element 121 has a pressure surface 128, via which the conductor 300 to be connected can operate the holding element 121. The pressure surface 128 is oriented toward the direction of introduction E of the conductor 300. The pressure surface 128 is arranged in alignment with the conductor lead-in opening 211. The holding element 121 with its pressure face 128 delimits the conductor connection space 110 downwards.

As can be seen in particular in fig. 1, by arranging the bus bar section 112, which is guided through the opening 127, between the pressure face 128 and the fastening section 120, the pressure face 128 is separated from the fastening section 120 of the holding element 121 by the bus bar section 112. Therefore, the busbar section 112 also separates the conductor connection space 110 from the fixing section 120 of the holding element 121, so that the fixing section 120 for holding the clamping leg 115 of the clamping spring 113 in the open position is not arranged precisely in the region of the conductor connection space 110, as shown in fig. 1.

To move the clamping legs 115 from the clamping position to the open position, each connection assembly 100 further comprises an operating element 129. The operating element 129 can be guided linearly in the operating direction B. The operating direction B extends parallel to the lead-in direction E of the conductor 300. The actuating element 129 can be guided parallel to the longitudinal extension of the busbar section 112. The actuating element 129 acts on the end section 119 of the clamping leg 115 in order to actuate the clamping leg 115. The actuating element 129 thus acts on the clamping leg 115 of the clamping spring 113 outside the conductor connection space 110 in order to actuate it. A bus bar section 112 is arranged between the conductor connecting space 110 and the operating element 129, so that the bus bar section 112 forms a spatial separation between the conductor connecting space 110 and the operating element 129.

The conductor connection space 110 extends between the bearing point 130 of the clamping spring 113 at its arc-shaped section 116 and the busbar section 112. The busbar section 112 is arranged between a bearing point 130 of the clamping spring 113 at its arc-shaped section 116 and the operating element 129.

For actuating the clamping leg 115, the actuating element 129 has an actuating surface 132 at its front end 131. The front end 131 points in the direction of the fastening section 120 of the holding element 121.

In the connecting assembly 100 shown on the left in fig. 1, the clamping leg 115 of the clamping spring 113 is in the open position, so that the conductor 300 to be connected can be introduced. The clamping legs 115 engage with their end sections 119 with the fastening sections 120 of the holding element 121, so that the clamping legs 115 are held in the open position.

In the connecting assembly 100 shown on the right in fig. 1, the clamping leg 115 is in the clamping position, wherein the clamping leg 115 is disengaged from the fastening section 120 of the holding element 121. In the connecting assembly 100 shown on the right in fig. 1, the lead-in conductor 300 is connected.

To release the conductor 300 from the clamped position, the operating element 129 can be operated by means of a tool 400 in order to move the operating element 129 in the operating direction B. By means of the actuation of the actuating element 129, the actuating element 129 presses the clamping leg 115, so that the clamping leg 115 is moved away from the clamping position in the direction of the fastening section 120 of the holding element 121 until the clamping leg 115 engages again with the fastening section 120 of the holding element 121. The clamping legs 115 are then again in the open position and the conductor 300 can be removed from the connection assembly 100.

The fastening element 129 has an actuating projection 133 on its front end 131, wherein an actuating surface 132 for actuating the clamping leg 115 is formed on the actuating projection 133. The operating projection 133 has a smaller cross section than the rest of the operating element 129. The actuating projection 133 is of curved design, so that in the open position, the actuating element 129 can also engage with the fastening section 120 of the holding element 120 via its actuating projection 133, as can be seen in the connecting assembly 100 shown on the left in fig. 1. By virtue of the curved design of the actuating projection 133, the actuating projection 133 forms a receiving space into which the fastening section 120 can be inserted or hooked in the open position of the clamping leg 115.

On a front end 134 of the operating element 129 opposite the front end 131, a display element 135 for displaying the connection state of the electrical conductor 300 to be connected is formed on the operating element 129. The display element 135 is thus formed at the free end of the operating element 129. The display element 135 is oriented such that it points away from the holding element 121.

As can be seen in the connection assembly 100 shown on the left in fig. 1, 2 and 4, the operating element 129, in the open position of the clamping leg 115, penetrates into the housing 210 to such an extent that the display element 135 is located inside the housing 210 and is therefore not visible to the user from the outside.

When the clamping legs 115 are transferred from the open position into the clamping position, the operating element 129 is moved upward, wherein when the clamping position is reached, the operating element 129 is moved upward to such an extent that the display element 135 protrudes from the opening 212 of the housing 210 and is thus visible to the user, as can be seen in the connecting assembly 100 shown in fig. 1, 2 and 4 on the right, respectively. The user can recognize that the conductor 300 is connected through the display element 135 protruding from the opening 212. The opening 212 is provided on the same side of the housing 210 as the conductor introduction opening 211.

In the exemplary embodiment shown here, the display element 135 is designed in the form of a tab-shaped extension at the end section of the operating element 129. In the clamped position of the clamping leg 115, the display element 135 projects from the opening 212 of the housing 210 with at least one subsection of the tab-shaped extension, so that the portion of the tab-shaped extension or of the display element 135 projects outward beyond the housing 210.

The operating element 129 has a tool receiving region 136 in the region of the display element 135, into which a tool, for example a screwdriver, can be introduced in order to operate the operating element 129. The tool receiving area 136 is formed in the form of a groove or slot.

In order to be able to hold the actuating element 129 in the open position of the clamping legs 115 in a fixed position on the holding element 121, so that in particular the display element 135 also remains immersed in the housing 210 and does not protrude from the opening 212, the actuating element 129 can be hooked or hooked by means of its actuating projection 133 onto the fixing section 120 of the holding element 121.

Since the operating element 129 is in the embodiment shown here in operative connection with the spring element 137. As can be seen in fig. 2, the spring element 137 is arranged at least in half in a recess 138 formed on the actuating element 129. A recess 138 extends between the two

front ends

131, 134 along a longitudinal side of the operating element 129. The spring element 137 is recessed with the other half into a recess 213 formed on the housing 210. By means of the movement or operation of the operating element 129, the recess 138 of the operating element 129 is moved relative to the recess 213 of the housing 213, whereby the spring element 137 is transferred into the tensioned state (as it is shown in the assembly shown on the left in fig. 2) and into the relaxed state (as it is shown in the assembly shown on the right in fig. 2). In the open position of the clamping legs 115 of the clamping spring 113, the spring element 137 is in a tensioned state. In the clamping position of the clamping leg 115 of the clamping spring 113, the spring element 137 is in a relaxed state.

Fig. 5 shows three connecting devices 200 arranged next to one another, wherein in one connecting assembly 100 the clamping legs 115 of the clamping spring 113 are unintentionally transferred from the open position into the clamping position without conductors 300 having been introduced. This is visible to the user via the display element 135 protruding from the housing 210, so that the user can, with the aid of the tool 400, as shown in fig. 6, operate the corresponding operating element 129 and can thus pivot the clamping legs 115 back into the desired open position again, so that in all connecting assemblies 100 of the connecting device 200 the clamping legs 115 are in the open position and can introduce the conductor 300 to be connected.
