Description
Technical Field
The invention relates to an electrical connector having at least one connecting block and a plug block separate from the connecting block. The invention also relates to a modular system for forming different plug connectors that can be configured as required and to a method for providing plug connectors by means of such a modular system.
Background
It is known to provide electrical connectors with a wire connection which is designed as a spring-force clamping connection. Such a connector is described, for example, in DE 102010048698B 4.
Disclosure of Invention
The invention is based on the object of optimizing such an electrical connector with regard to application feasibility and manufacturing effort.
The object is achieved by an electrical connector having at least one connection block and a connector block separate from the connection block, having the following features:
a) the connecting block has at least one clamping spring of the spring force clamping connection and an insulating material housing at least partially enclosing the clamping spring;
b) the plug block has at least one electrical plug contact and an insulating material housing which at least partially surrounds the plug contact, wherein the plug contact can be electrically contacted on the plug face side of the plug block by an associated plug contact of a mating plug which is associated with the plug as a mating piece;
c) the insulating material housing of the connection block has a first connection side;
d) the insulating material housing of the plug-in block has a second connection side, which is not the plug-in face side;
e) the first and second connection sides are associated with one another as mating pieces, so that the connection block and the plug block can be connected to one another by joining their respective insulating material housings together on the first and second connection sides associated with one another to form a plug connector.
The electrical connector according to the invention is thus advantageously designed in at least two parts, namely with a connecting block and a plug block separate from the connecting block. In this way, the part of the electrical connector with the line connections in the form of spring-force clamping connections is arranged in the module "connection block", while the part of the connector with the plug contacts, which is responsible for forming the plug-in connection, is arranged in the further module "plug-in block". In this way, for example, a universal connection block can be provided which can be used for a plurality of applications, for example for forming different connectors, for example connectors with different pole counts, different plug surfaces, connectors with different types of plug contacts, for example pin contacts or socket contacts, or for other applications as electrical connectors.
Accordingly, the connecting block with the at least one clamping spring in its insulating material housing is joined to the plug block with the at least one electrical plug contact in its insulating material housing, thereby forming a plug connector.
The assembly of the plug block to the connection block is not carried out on the plug face side, but on the other side, i.e. on the second connection side. The second connection side can be, for example, a housing side facing away from the plug-in side, or any different housing side.
It is known to refer to the front side of the plug connector, on which the mating plug connector is plugged, as the plugging surface of the plug connector. The plug surface has corresponding contours and profiles, which are designed as mating pieces for mating with the associated plug surface of the plug connector. In general, a clear assignment of the plug connector to the mating plug connector should be ensured by the profile and the contour, for example by coding.
The plug contact may be a female plug contact or a male plug contact, such as a contact pin, a contact blade or a contact socket.
A further advantage of the invention is that plug blocks of different embodiments can be provided, for example plug blocks with plug contacts of different configurations, for example male/female or plug contacts of different sizes. In this way, the respectively required connectors can be provided in combination with the corresponding connection block, i.e. with the desired properties on the plug contact side.
The invention is suitable for providing single-pole or multi-pole electrical connectors. In the case of a multi-pole electrical connector, it is advantageous if the connecting block has a plurality of clamping springs, the number of which corresponds to the number of plug contacts of the connector. In this case, a clamping spring is associated with each plug contact.
The clamping spring, for example the clamping leg of the clamping spring, can form a clamping point for the fixed clamping of the electrical line, if appropriate in combination with a further part, for example a busbar. In order to open the clamping point, the clamping spring, for example the clamping leg, can be actuated by an external tool, for example by a screwdriver. The connection block may have its own busbar or busbar piece, which is part of the connection block.
According to an advantageous further development of the invention, it is provided that the connecting piece has at least one first fixing element, by means of which at least one clamping spring can be fixed in the connecting piece before the connecting piece and the plug-in piece are joined together. The clamping spring can be already fixed in the connecting piece, in particular in the insulating material housing of the connecting piece, by means of such a first fixing element, so that at least the joining together of the connecting piece and the plug-in piece can be achieved without problems, without the clamping spring changing its position undesirably or even falling out. The fastening by means of the first fastening element does not necessarily have to be effective in all spatial directions, i.e. the fastening does not necessarily have to be effective in any movement performed with the individual connecting pieces. However, the fixing must at least be carried out such that the previously mentioned problem-free connection of the connection block to the plug-in block is possible. It goes without saying that the first fixing element can also be designed such that the clamping spring is fixed in the connecting piece in all spatial directions. The first fixing element can be formed, for example, on the insulating material housing of the connection block or on another part of the connection block, for example on the actuating element.
According to an advantageous further development of the invention, it is provided that the plug block has at least one second fixing element, by means of which at least one electrical plug contact can be fixed in the plug block before the connection block is joined together with the plug block. The second fixing element can fix the electrical plug contact in the plug block, in particular in the insulating housing of the plug block, so that the connection of the connection block to the plug block can be achieved at least without problems, without the electrical plug contact changing its position undesirably or even falling out. The fastening by means of the second fastening element does not necessarily have to be effective in all spatial directions, i.e. the fastening does not necessarily have to be effective in any movement performed with the individual plug blocks. However, the fixing must at least be carried out such that the previously mentioned problem-free connection of the connection block to the plug-in block is possible. It goes without saying that the second fixing element can also be designed such that the electrical plug contact is fixed in the plug block in all spatial directions.
The first and/or second fixing element can be designed, for example, as a latching element, for example, as a latching hook, latching edge, latching recess or the like, and/or as an undercut and/or clamping section, for example, on one or more of the previously mentioned components of the connecting and/or plug-in block.
According to an advantageous further development of the invention, it is provided that the electrical plug contact has a contact element which can be brought into contact with the plug block, wherein the contact element can be brought into electrical and/or mechanical contact with at least one region of the clamping spring only when the connecting block is plugged together with the plug block. This has the advantage that an electrical and/or mechanical connection between the electrical plug contact and the clamping spring can be established by plugging the connection block and the plug block together. The contact element is designed as a plug-in contact element, which can be simply plugged together, like a plug, with the region of the clamping spring or released again if required. When the connecting block is joined to the plug block, the region of the clamping spring, for example a part of the support leg of the clamping spring, thus forms a plug connection with the contact element which can be brought into contact with the plug.
In this way, for example, the plug contact and the clamping spring can each have a connecting section which, after joining the connecting block and the plug block together, engages one another, for example by forming a form-fitting and/or force-fitting connection with one another. Such a connecting section can be formed, for example, by a retaining projection at the plug contact and the free end of the support leg of the clamping spring, which free end is overlapped by the retaining projection in the joined-together state. The connecting sections can be positioned relative to the respective insulating material housing by fixing the plug contacts in the plug block and the clamping spring in the connecting block, so that the connecting sections are arranged opposite each other when the plug block is placed on the connecting block (or vice versa), so that these connecting sections also engage each other during the joining together. Accordingly, the contact element, which can be brought into contact with the plug, can form one connecting section and the end region of the support leg of the clamping spring forms the other connecting section.
According to an advantageous further development of the invention, it is proposed that the connecting piece as a further component has an actuating element, in particular an actuating lever or an actuating button, by means of which the clamping leg of the clamping spring can be deflected by manual actuation in order to open the clamping point formed by means of the clamping leg. This has the advantage that the connecting piece already has its own operating possibility for opening the clamping point, i.e. the operating element, which is thus part of the connecting piece. If an operating button is used, it is supported, for example, in a linearly displaceable manner in an insulating material housing. If an actuating lever is used, it is, for example, pivotably supported in an insulating material housing.
According to an advantageous further development of the invention, it is provided that the connector has an electrical connection element by means of which the plug contact is electrically connected to the clamping spring or to an electrical line which is clamped fixedly by the clamping spring when the connecting block is joined to the plug block. This results in a reliable electrical contact between the plug contact and the clamping spring or the electrical conductor clamped securely there. The electrical connection element can be designed, for example, as a busbar, on which the clamping legs of the clamping spring can be supported when the connection block and the plug block are joined together. It goes without saying that the clamping leg is supported on the busbar only when the electrical conductor is not clamped securely between the clamping leg and the busbar. Otherwise, the clamping legs rest on the electrical conductor.
According to an advantageous further development of the invention, it is provided that the electrical connection element is designed as a busbar on which the clamping legs of the clamping spring can be supported when the connection block and the plug block are joined together.
The electrical connection element may be provided as a separate component and mounted in the plug connector.
According to an advantageous further development of the invention, it is provided that the electrical connection element is formed integrally with the plug contact. This has the advantage that the electrical connection element is provided at the same time as the plug contact, so that it does not have to be additionally installed as a separate component. This simplifies the installation of the plug connector. Furthermore, the electrical contact on the plug contact is improved.
According to an advantageous further development of the invention, it is provided that the clamping spring has a support leg, via which the clamping spring can be supported against the force of the clamping leg, wherein the electrical connection element has a retaining body, on which the support leg is fixed when the connection block is joined together with the plug block. In this way, a secure retention of the clamping spring in the connector is ensured. A reliable and stable support of the clamping spring can be achieved by using a holding body of the connecting element. Furthermore, no additional components for holding the clamping spring are required, so that the installation of the connector is simple in design and correspondingly less complicated to produce.
According to an advantageous further development of the invention, it is provided that the clamping spring and the plug contact form a self-supporting contact insert in the joined-together state of the connecting block and the plug block. When the connecting block and the plug block are joined together, the clamping or spring force is advantageously not transmitted to the insulating material housing.
According to an advantageous further development of the invention, the connecting block is designed without a busbar. In this case, the connecting block does not have its own bus bar or bus bar piece at all. This is also necessary for a simple and cost-effective design of the connection block and thus of the plug connector.
According to an advantageous further development of the invention, it is provided that the connecting piece has at least one first coupling element and the plug-in piece has at least one second coupling element, wherein the connecting piece can be fixed to the plug-in piece by the interaction of the first coupling element and the second coupling element. The connecting block and the plug block each thus have their own coupling elements, so that these components can be easily coupled to one another. The first and second coupling elements can be designed as latching elements, for example, i.e. one coupling element can have a latching edge, for example, and the other coupling element can have a latching projection, so that the latching projection can latch behind the latching edge.
According to an advantageous further development of the invention, it is proposed that the connector is designed as a multi-pole connector having a plurality of plug contacts which are electrically isolated from one another and the connecting block has a number of clamping springs corresponding to the number of plug contacts, wherein clamping springs are associated with the plug contacts in each case.
The object mentioned at the outset is also achieved by a method for providing a connector of the type stated above, which is characterized in that a connecting block having at least one clamping spring in its insulating material housing is joined to a plug block having at least one electrical plug contact in its insulating material housing, thereby forming a connector. The advantages set forth above are also achieved thereby.
The object mentioned at the outset is also achieved by a modular system for forming different plug connectors which can be configured as required, wherein the system has a plurality of identically or differently formed connecting blocks and a plurality of identically or differently formed plug blocks, having the following features:
a) the connection block has at least one clamping spring for spring force clamping the connection piece and an insulating material housing at least partially enclosing the clamping spring,
b) the plug block has at least one electrical plug contact and an insulating material housing which at least partially surrounds the plug contact, wherein the plug contact can be electrically contacted on the plug-face side of the plug block by an associated plug contact of a mating plug which is associated with the plug as a mating piece,
c) the insulating material housing of the connection block has a first connection side,
d) the insulating material housing of the plug-in block has a second connection side, which is not the plug-in face side,
e) the first and second connection sides are associated with one another as mating pieces, so that the connection block and the plug block can be connected to one another by joining their respective insulating material housings together on the first and second connection sides associated with one another,
f) in which a single-pole or multi-pole plug-in connector can be formed in such a way that one or more connection blocks are joined together with one or more plug-in blocks of the system according to the user's choice.
The advantages set forth above are also achieved thereby. In particular, different connectors, for example connectors with different types of plug contacts or connectors with different numbers of poles, can be provided by means of the modular system.
The system may have connection blocks which are only of identical design, for example only unipolar connection blocks or only bipolar or tripolar connection blocks, or connection blocks with a higher number of poles. The system may also have differently configured connection blocks, for example unipolar, bipolar or tripolar connection blocks, or higher-pole connection blocks. A similar situation applies to the plug-in blocks of the system. The system may have plug blocks of only identical design, for example only unipolar, bipolar or tripolar plug blocks, or plug blocks of different design, as in the connecting block. This allows great flexibility in forming different connectors that can be configured as desired.
The object mentioned at the outset is also achieved by a method for providing a plug connector by means of a modular system of the type set forth above, having the following steps:
a) one or more connection blocks of the system are selected,
b) one or more patch blocks of the system are selected,
c) the first connecting side of the connecting block and the second connecting side of the plugging block are joined together.
The advantages set forth above are also achieved thereby.
The indefinite article "a" or "an" is not to be understood as a quantity of words in the sense of the present invention. I.e. if for example components are mentioned, this is to be interpreted as meaning "at least one component". As long as the angular specification is in degrees, the angular specification relates to a circle size of 360 degrees (360 °).
The invention is explained in detail below on the basis of embodiments using the drawings.

Detailed Description
The electrical connector shown in fig. 1 has a connection block 1 and a connector block 6. The plug-in block 6 is formed as a separate component from the connecting block 1. In the illustration of fig. 1, these components have been joined together. This is also illustrated later according to fig. 5 with separate, yet unjoined parts.
The connecting block 1 has an insulating material housing 2 and a clamping spring 4 which is arranged at least predominantly within the insulating material housing 2, and an operating element 5 which is in this case designed as an operating lever.
The insulating material housing 2 has a conductor insertion opening 20 through which an electrical conductor can be inserted into the insulating material housing 2 in a conductor insertion direction L and can be guided to the clamping point 32. The side of the insulating material housing 2 opposite the conductor insertion opening 20 is configured to be as open as possible. On this side, the plug-in block 6 is connected to the connecting block 1.
The clamping spring 4 has a support leg 40, a spring bracket 42 connected to the support leg 40, and a clamping leg 43 connected to the spring bracket 42. The clamping legs 43 terminate at their free ends with clamping edges 44, which serve to clamp the electrical line securely.
The plug block 6 has an insulating material housing 2 and plug contacts 8 arranged substantially within the region enclosed by the insulating material housing 2. The insulating material housing 7 has an opening 70 on the plug face side 60, through which a plug contact associated as a mating piece with the plug contact 8 can be introduced in order to establish an electrical connection with the plug contact 8. The plug contact 8 is connected to the clamping spring 4 via an electrical connection element 30. The electrical connection element 30 extends beyond the clamping point 32 into the insulating material housing 2 of the connection block 1. The clamping point 32 for clamping the electrical conductor is thus formed between the clamping edge 44 and the region of the electrical connection element 30 opposite the clamping edge 44. If the electrical line is to be clamped securely at the clamping point 32, the electrical line is introduced into the insulating material housing 2 through the line introduction opening 20 in the line introduction direction L and is clamped securely between the clamping edge 44 and the electrical connection element 30 at the clamping point 32.
In order to introduce the electrical line into the clamping point 32 and to simplify the removal of the electrical line, an actuating element 5 is present. The actuating element 5 has a manual actuating region 50, for example in the form of a handle, from which the actuating element 5 extends on both side walls 51 toward the electrical connection element 30. The actuating element 5 can be supported on the electrical connection element 30 via two side walls 51. The side wall 51 extends within the insulating-material housing 2 or partially outside the insulating-material housing 2, for example by overlapping the insulating-material housing 2. Spring followers 52 are provided on the side walls 51 on the inner side, i.e. on the side facing the clamping spring 4, for example, molded integrally on the clamping spring.
If the actuating element 5 is pivoted by manual actuation on the actuating region 50 in the counterclockwise direction with respect to the position shown in fig. 1, the clamping leg 43 is deflected upward by the spring catch 52, so that the clamping edge 44 is lifted off the electrical connection element 30 and continues to move. In this way, the clamping point can be opened, so that the fixedly clamped electrical line can be removed or the electrical line to be clamped can be easily introduced.
A holding body 31 having at least one holding projection 33 for holding a support leg 40 of the clamping spring 4 is molded onto the electrical connection element 30. The support leg 40 is hooked with its free end behind the at least one retaining projection 33.
A line stop 34 is also provided on the electrical connection element 30, by means of which the insertion depth of the electrical line is limited. If the electrical line is introduced in the line introduction direction L, it impinges on the line stop 34 at a certain point in time, so that the user can tactually detect that the electrical line has reached the maximum introduction depth.
Fig. 2 shows an electrical connector of the type shown in fig. 1 in a different embodiment. In the upper view of fig. 2, an electrical plug contact 8 is shown in the form of a pin contact or a blade contact. In this case, the respective connecting pin or blade forming the plug contact 8 can be formed in one piece with a sheet metal part which also has an electrical connection element 30 with a respective retaining body 31. For example, a connecting pin or a connecting blade may protrude from the respective retaining body 31.
In the upper illustration of fig. 2, it is apparent that the actuating element 5 is at least partially open, so that the support leg 40 of the clamping spring 4 arranged therebelow is visible. In this state, for example, the connection block 1 and the plug block 6 can be advantageously joined together. In order to be able to introduce the free ends of the support legs 40 into the recesses of the holding body 31 formed below the holding projections 33 in a targeted manner, pressure can be applied to the support legs 40 from the outside, for example in the case of automated mounting on a mounting machine.
In the middle illustration of fig. 2, a plug connector with a plug contact 8 of another type is shown, in this case in the form of a socket contact with two contact tongues, which each project from a retaining body 31. Also visible is a wire stop 34. In the middle illustration, it is also known that the actuating element 5 and the clamping spring 4 are not installed. In order to show the position of the actuating lever 5, the contact surfaces or contact points of the side walls 51 of the actuating lever 5 on the electrical connection element are shown with cross-hatching.
In the lower view of fig. 2, the plug connector is shown in an undivided illustration and with the operating element 5 in the closed position. Visible is an operating element 5 having a manual operating region 50 and a side wall 51 projecting in a U-shaped manner from manual operating region 50.
Fig. 3 shows the electrically active components of the connector, namely the clamping spring 4 and the one-piece metal part, from which the electrical connection element 30, the retaining body 31 with the retaining projection 33, the wire stop 34 and the plug contact 8 are formed, in a separate illustration, in this case again in the form of a contact spring. The illustrated element can be designed as a self-supporting contact insert, i.e. the clamping spring 4 is already left in the illustrated position without the aid of additional auxiliary elements, since it is suspended behind the retaining projection 33 by means of the support leg 40 and is supported on the other side, i.e. on the side of the clamping leg 43, on the electrical connection element 30 by means of the clamping edge 44.
Fig. 4 shows the manner in which the actuating element 5 has the already described elements. The following U-shaped design of the actuating element 5 is again visible: gaps are formed between the side walls 51 and/or the spring drivers 52, through which electrical lines can be guided for clamping on the clamping points 32. The electrical lines are guided on both sides during insertion by spring catches 52 molded onto the side walls 51 in the form of circular segments and facing each other. This allows a very compact constructed embodiment of the spring clamping connection.
Fig. 5 shows the connection block 1 and the plug block 6 as separate elements, i.e. before joining together, as they have already been shown in fig. 1. It can be seen that the connecting piece 1 has a connecting side 29. The plug block 6 has a second connection side 69, which is arranged opposite the plug surface side 60. The metal component with the electrical connection element 30, the retaining body 31, the wire stop 34 and the plug contact 8 has been inserted into the insulating material housing 7 of the plug block 6. The clamping spring 4 has been inserted into the insulating material housing 2 of the connection block 1. The connecting piece 1 is now joined to the plug-in piece 6, so that the first coupling elements 21, 22 are locked with the second coupling elements 71, 72. This results in the plug connector according to fig. 1.
Fig. 5 also shows that the clamping spring 4 is already fixed in the connecting piece 1 before the engagement with the plug-in piece 6 and accordingly cannot be easily removed. In this case, a region of the insulating-material housing 2 forms a bearing surface so as to form a first fixing element 80 for fixing the clamping spring 4. In the exemplary embodiment shown, the clamping spring 4 is supported with its spring bracket 42 and/or the support leg 40 on the first fastening element 80. In addition, the spring catch 52 forms a further first fixing element 81 which fixes the clamping spring 4 in the region of the clamping leg 43 in the connecting piece 1. The clamping spring 4 is thereby essentially clamped between the first fixing element 80 and the second fixing element 81.
In the plug block 6, second fixing elements 82, 83 are present, which ensure the fixing of the plug contact 8 in the plug block 6 at least before the joining together of the connection block 1. The second fixing elements 82, 83 can be formed, for example, by the inner wall of the insulating material housing 70, in which the region of the plug contact 8, for example a fork-shaped spring, is guided. The plug contact 8 does not have to be clamped securely between the second fastening elements 82, 83, which is also disadvantageous for the function of the plug contact. Rather, a large guide length of the plug contact 8 between the second fixing elements 82, 83 can be sufficient to achieve sufficient fixing of the plug contact 8 and thus fastening of the plug contact 8 in the plug block 6.
For the mechanical and/or electrical connection between the clamping spring 4 and the plug contact 8, an additional plug-in coupling is provided, which is formed by an insertion region 85 of the clamping spring 4 and a recess below the holding projection 33 on the side of the plug contact 8, which recess forms a contact element 84 for the plug contact. The insertion region 85 can be simply inserted into the contact element 84 when the connecting block 1 is joined to the plug block 6, as can also be seen in fig. 1. The contact element 84 of the plug-in contact may have a region which, viewed in the direction of engagement of the connection block with the plug block 6, is formed with an undercut, for example by a corresponding contour of the retaining projection 33. The insertion region 85 is thereby additionally connected to the pluggable contact element 84 by means of a form fit.
