The circuit board terminal can also have different types of circuit board connection contacts mixedly. Circuit board terminals are known, for example, from DE 20 2007 008 700 U1. Summary of the invention

[0003] The invention is based on the object of combining such a printed circuit board terminal with at least one electrical plug connector contact in an efficient manner.

[0004] The object is achieved in the case of a device of the type mentioned at the outset in that the device has a contact bridge, via which at least one electrical plug connector contact can be electrically connected to the contact plug directly or indirectly via at least one further component of a circuit board terminal which is connected to the contact plug. The invention has the advantage that already existing commercially available circuit board connection terminals can be combined with electrical plug connector contacts in a simple manner in order to provide a particularly effective electrical connection unit for connecting electrical conductors to a printed circuit board in this manner. In this case, the user can select the type and design of the electrical plug connector contacts to be used.

[0005] The contact bridge according to the invention enables an advantageous interface of, in principle, any electrical plug connector contact to an already available printed circuit board terminal. In principle, the invention allows any type of plug connector contact to be matched to any type of printed circuit board terminal. The printed circuit board terminal can continue to be used in the conventional manner of a printed circuit board terminal, for example, it can be soldered to a printed circuit board by means of its solder connection contact or plugged into a printed circuit board by means of its plug connection contact.

[0006] Therefore, the present invention can realize the fixing or contacting of the plug connector contact part with the circuit board terminal. Therefore, the connection of at least one plug connector contact part with the circuit board terminal or the circuit board can be realized through simplified installation steps.

[0007] According to an advantageous embodiment of the present invention, at least one circuit board connection contact is configured as a solder connection contact extending from a circuit board connection side of the housing, wherein the solder connection contact is configured to be soldered to a solder connection end of a circuit board.

[0008] According to an advantageous design of the present invention, at least one circuit board connection contact portion is configured as a plug connection contact portion, and the plug connection contact portion is configured to be plugged into a plug connection end of a circuit board. Such a plug connection contact portion can be contacted, for example, at the circuit board connection side of the housing. The circuit board terminal can also be configured in combination with one or more solder connection contacts and one or more plug connection contacts.

[0009] According to an advantageous design of the present invention, the contact bridge is configured to be connected to at least one circuit board connection contact of a circuit board terminal. Thus, the contact bridge can be directly connected to at least one circuit board connection contact. This utilizes an advantageous contact possibility for the contact bridge, which is usually present in circuit board terminals of common structural types, so that the circuit board terminal does not need to be modified. The contact bridge can also be connected to multiple circuit board connection contacts of the circuit board terminal.

[0010] The housing of the printed circuit board terminal can be designed as an insulating material housing. The printed circuit board connection side of the housing is configured to point toward the printed circuit board surface or directly abut against the printed circuit board surface when the printed circuit board terminal is mounted on the printed circuit board.

[0011] According to an advantageous design of the present invention, the housing of the printed circuit board terminal has a wire insertion opening, which is configured to introduce the electrical wire to be clamped into the housing to the clamping position of the contact plug. The electrical wire can be easily guided into the housing to the clamping position and clamped there in the described manner.

[0012] According to an advantageous embodiment of the invention, the housing of the printed circuit board terminal has at least one further opening in addition to the wire insertion opening, in particular a further opening separate from the wire insertion opening, through which the contact plug can be electrically contacted directly or indirectly via at least one further component of the printed circuit board terminal connected to the contact plug, wherein a contact bridge can be introduced into the housing through the further opening and connected directly or indirectly to the contact plug. This makes use of another advantageous connection possibility for the contact bridge and thus for the plug-in connector contact at the printed circuit board terminal, namely the further opening of the housing that is present anyway. The opening can be, for example, a bridge opening for connecting a bridge or a test opening for connecting a test contact, in order to test the voltage applied to the contact plug, for example by means of a measuring device.

[0013] According to an advantageous design of the present invention, the contact bridge has at least one spring-elastically deflectable contact leg, through which a component of the circuit board terminal can be electrically contacted under spring preload. This has the following advantages: the contact bridge can be releasably connected to at least one circuit board connection contact and / or a part of a contact plug, such as a busbar or a component of the contact plug connected thereto, under spring preload, for example, in a plug-in connection. The spring preload ensures a reliable mechanical fixation and at the same time a good electrical contact.

[0014] According to an advantageous design of the present invention, the printed circuit board terminal has a plurality of contact plugs to which electrical conductors can be clamped, respectively, wherein the contact bridge can be connected to a plurality of contact plugs of the printed circuit board terminal. In this way, a mechanically more stable connection with the contact plug can be established with improved electrical conductivity. The printed circuit board terminal can be designed, for example, as a multi-pole printed circuit board terminal, wherein the housing can be divided into a plurality of housing sections or housing chambers, and a respective contact plug is arranged in each housing section or housing chamber.

[0015] According to an advantageous design of the present invention, the contact bridge is formed in one piece with at least one electrical plug connector contact. This allows the plug connector contact with the contact bridge to be simply and quickly placed at the circuit board terminal. For example, the contact bridge can be formed together with the plug connector contact from a sheet metal part, for example, by a stamping-bending process. Alternatively, the contact bridge can also be connected to the plug connector contact in other ways, for example, by soldering, welding and / or bonding. A form-fitting coupling between the contact bridge and the plug connector contact is also feasible.

[0016] According to an advantageous design of the present invention, the circuit board terminal is configured as a spring force terminal, wherein the contact plug has at least one clamping spring, which is used to clamp the electrical conductor at the clamping point by means of spring force. In this way, the electrical conductor can be advantageously clamped by means of spring force, which enables simple and rapid connection and permanent connection of the electrical conductor.

[0017] The contact plug can have a busbar as a further component. The electrical conductor is then clamped at the busbar at the clamping point by means of a clamping spring.

[0018] The printed circuit board terminal can be designed without its own actuating element. Then, for example, the clamping spring of the contact plug-in can be actuated by means of a separate tool, such as a screwdriver, to open the clamping location.

[0019] According to an advantageous design of the present invention, the circuit board terminal has at least one manual operating element for operating the clamping spring. This has the following advantages: the user can open the clamping position in a simple and quick manner, namely by operating the manual operating element of the circuit board terminal. A separate tool is not necessarily required for this purpose. Therefore, the operating element is a component of the circuit board terminal. The manual operating element can be configured, for example, as a pivotable operating lever or a movable pressing piece.

[0020] According to an advantageous embodiment of the invention, it is provided that at least one plug connector contact is designed as a socket contact, a pin contact or a blade contact. This allows for a wide range of possibilities for use of the device according to the invention.

[0021] For the purposes of the present invention, the indefinite article "a" is not to be understood as a numeral. That is to say, for example, if a "component" is mentioned, this is to be interpreted in the sense of "at least one component". Whenever an angle is specified in degrees, it relates to a circle size of 360 degrees (360°). BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Reference Figures 1 to 3 A first embodiment of the present invention is described. A circuit board terminal 1 having a housing 2 can be seen. The housing 2 has a circuit board connection side 20, which, when the circuit board terminal 1 is connected to the circuit board, points to the circuit board surface, for example, to the assembly side of the circuit board. The circuit board connection side 20 is Figure 1 In the diagram, it is in the lower part. Figure 2 is at the top in the illustration.

[0038] The circuit board terminal 1 has a manual actuating element 5 for actuating a clamping spring of a contact plug of the circuit board terminal 1 arranged in the housing 2. The actuating element 5 can be arranged, for example, on a housing side of the housing 2 facing away from the circuit board connection side 20 or can be manually actuated at least on such a housing side.

[0039] Also visible is a plug connector contact 3, for example in the form of a fork-shaped contact, which can be plugged together with an associated plug contact as a counterpart in order to form an electrical plug connection. The plug connector contact 3 is connected to a contact bridge 4, which serves to electrically connect the plug connector contact 3 to a contact insert of the circuit board terminal 1.

[0040] The contact bridge 4 has a contact section 40 which is configured for being arranged on the circuit board connection side 20 of the housing 2. The contact section 40 is designed as a substantially flat plate section in which at least one recess 42 is arranged, wherein in the illustrated embodiment there are two recesses 42 spaced apart from one another. In the region of the respective recess 42, the contact section 40 has a spring-elastically deflectable contact leg 41 which can be formed in one piece from the material of the contact section 40, for example, in a stamping-bending process. As shown, such a contact leg 41 can be arranged in each of the recesses 42. For example, the contact legs 41 can be arranged with their free ends in directions facing away from one another.

[0041] The circuit board terminal 1 has a plurality of circuit board connection contacts 6, which are accessible at the circuit board connection side 20 or protrude from the housing 2 at the circuit board connection side 20. The circuit board connection contacts 6 can be designed, for example, as solder connection contacts (solder pins), which can be soldered to corresponding solder connections of a circuit board. Figure 2 As can be seen in the figure, the contact bridge 4 can be connected to the circuit board terminal 1 simply by plugging into the circuit board connection contact part 6 of the circuit board terminal 1 with the help of the contact section 40, in that the circuit board connection contact part 6 extends through the corresponding recess 42 and is pressed against the edge of the recess 42 with the help of the corresponding contact leg 41, so that the circuit board connection contact part is connected there with the contact section 40 in a plug-in connection.

[0042] The contact section 40 is connected to the plug connector contact 3 via the bridge section 43 of the contact bridge 4, for example is integrally formed therewith. In the embodiment shown, the bridge section 43 is designed as a relatively short, rectilinear sheet metal section.

[0043] Reference Figures 4 to 6 A second embodiment of the device according to the invention is described. Figures 1 to 3 Unlike the embodiment of the present invention, the circuit board terminal 1 is designed as a circuit board terminal with two housing sections arranged side by side, in which contact plugs are respectively arranged. A manual operating element 5 for operating the corresponding contact plug is arranged at each housing section. The plug connector 3 and the contact bridge 4 are designed essentially the same as in the first embodiment, wherein the contact section 40 is designed wider here, so that the contact section contacts the circuit board connection contact 6 of one contact plug on one side and contacts the circuit board connection contact 6 of the other contact plug on the other side by means of the contact legs 41, as in particular in Figure 5 As can be clearly seen in. Figure 6 It is shown that the contact section 40 is designed wider than in the first embodiment, and the cutouts 42 and the associated contact pins 41 are arranged laterally offset relative to each other and are not arranged one after the other in a line as in the first embodiment. Therefore, a plurality of contact plugs of the printed circuit board terminal 1 can be electrically contacted with the contact bridge 4 via such a contact bridge.

[0044] Reference Figures 7 to 11 A third embodiment of the invention is described. The circuit board terminal 1 again has a housing 2, which has a circuit board connection side 20 and a circuit board connection contact 6 accessible there. In addition, there is also an actuating element 5. The housing 2 has a wire insertion opening on the housing side, which is not visible in the figure, however. In addition to the wire insertion opening, the housing 2 has further openings 21, such as bridge openings or test openings.

[0045] The plug-in connector contact 3 and the contact bridge 4 can also be seen. In this case, the contact bridge 4 is shaped so that the contact section 40 can be inserted into the further opening 21 of the housing 2 in a manner similar to the plug-in connector and can directly make mechanical and electrical contact there with a part of the contact plug 7. As in the previously described embodiment, the plug-in connector contact 3 can be connected to the contact section 40 via a bridge section 43, wherein the bridge section 43 is shaped in a manner similar to the first embodiment. However, the illustrated figure shows another advantageous embodiment, in which the bridge section 43 is bent twice, more precisely twice in opposite bending directions, so that the bridge section 43 is visible in the side view (see FIG. 2 ). Figure 8 ) extends roughly in an S shape.

[0046] pass Fig.11 The design of the contact section 40 becomes clear, namely that it has two spring-elastic contact legs 41 at the free ends, which are located opposite each other. A free space is formed between the contact legs 41. The contact legs 41 preferably engage in openings of the contact plug 7, so that when the contact section 40 and the contact plug 7 are plugged together, the contact legs spring toward each other.

[0047] according to Fig.12 and Fig.13 A fourth embodiment of the device according to the invention is described. Fig.12 and Fig.13 The device of corresponds largely to the third exemplary embodiment, wherein here, similarly to the second exemplary embodiment, the printed circuit board terminal 1 has a plurality of contact plugs arranged side by side in the housing section. Correspondingly, there are also a plurality of actuating elements 5 arranged side by side for actuating each contact plug. In addition, the assembly with the plug connector contact 3 and the contact bridge 4 is designed similarly to the third exemplary embodiment, wherein as Fig.13 As shown, the contact section 40 is designed to be relatively wide, so that two plug contacts arranged side by side are formed therein, each of which has two mutually opposite spring-elastic contact legs 41. As a result, two plug contacts are formed on the contact section 40, each of which can be plugged together with a respective contact plug 7 of the printed circuit board terminal 1 in the manner described for the third exemplary embodiment.
