The door opener comprises an electrical arrangement, wherein the electrical arrangement comprises the following: a plastic part, preferably an injection-molded plastic part, a metallic part, preferably a stamped part, wherein the plastic part is designed as part of a housing for the door opener, wherein the plastic part is designed to receive a component of the housing, preferably a cover of the housing, which has punch elements that correspond to insulation displacement contacts of the metallic part to produce an insulation displacement connection, where the metallic part is positively connected to the plastic part by integrating the metallic part into the plastic part, and areas of the metallic part protrude from the plastic part for the purpose of electrical contacting, wherein the protruding areas of the metallic part are designed as insulation displacement contacts and as plug contacts.

[0030] The invention will be explained in more detail below with the aid of figures. These figures show: Fig. 1 a perspective view of a door opener according to the invention, viewed obliquely from above onto the front; Fig. 2 a perspective view of the door opener of the Fig. 1 , however, view towards the front before the insertion of the connecting cables; Fig. 2b Fig. 2a , however, after the connecting cables have been inserted with the movable terminal block in its mounted position, before the insulation displacement connection has been made; Fig. 2cwie Fig. 2b , however, in the operating position, i.e., in the contact position of the movable clamping block, in which the insulation displacement connection is made and held; Fig. 3a is an exploded view of the terminal block assembly of the embodiment shown in the preceding figures, viewing direction as in Fig. 2a ; Fig. 3bwie Fig. 3a , however, the viewing direction is rotated by 180°; Fig. 3bbwie Fig. 3b , however, with a conductor track shown on the circuit board; Fig. 4a a perspective view of the terminal block assembly with the coil of the electrically switchable locking device connected to it; Fig. 4b how Fig. 4a , however, the viewing direction is rotated by 180°.

[0031] The embodiment shown in the figures comprises the following components: a bearing and / or receiving frame - hereinafter referred to as door opener housing 2 -, an electrically switchable locking device 3 mounted in the door opener housing 2 with an output element which is designed as an armature 4 movable in the door opener housing 2 or actuates it, a door opener latch 1 which is movably, preferably pivotably, mounted in the door opener housing 2, a changeover 5 preferably designed as a single- or double-armed lever which is arranged between the armature 4 and the door opener latch 1 and is mounted in the door opener housing 2, wherein the changeover 5 interacts with the door opener latch 1 directly or via a gear unit.

[0032] In the exemplary embodiment, the anchor 4, the changeover 5 and the door opener latch 1 are connected in a line one after the other.

[0033] The electrically switchable locking device 3 can be electrically switched in a locking position and a release position such that in the locking position it switches the door opener latch 1 into a locking position and in the release position it switches the door opener latch 1 into a release position.

[0034] The door opener 10 shown in the figures has a terminal block for electrical connection via connecting cables 20x, which is designed as an assembly 20. This assembly comprises a first terminal block 21 as a housing-fixed terminal block, a second terminal block 22 as a movable terminal block, and a circuit board 23 which is housing-fixed to the first terminal block, as will be described in more detail below.

[0035] Regarding the installation of the door opener 10: The electric door opener 10 should – as is usually the case – be mounted on a fixed door frame and is associated with a lock mounted on the door leaf. The reverse installation is also possible, in which the electric door opener is mounted on the door leaf and the associated lock on the fixed door frame. The door can be – as is often the case – a revolving door with a hinged leaf.

[0036] The door opener 10 interacts with a latch of the associated lock via its door opener latch 1. This interaction is as follows: In the closed position of the door, the latch engages the door opener latch 1. In the locked position of the electrically switchable locking device 3, the door opener latch 1 is in the locked position. The door, in its closed position, is blocked against movement in the opening direction by the door opener latch 1, which is held in the locked position.

[0037] The door opener latch 1, when locked in the closed position, forms a fixed stop for the lock latch, preventing the door from moving in the opening direction. The lock latch cannot pass the locked door opener latch 1.

[0038] When the electrically switchable locking position 3 is switched to its release position, it sets the door opener latch in the release position. With the door opener latch in this position, the door can then be moved from the closed position to the opening position. In doing so, the lock latch passes over the now disengaged door opener latch 1. As the door opener latch 1 passes over the release force of its return spring, it is forced over the release force.

[0039] The latch can be designed as a spring-loaded, so-called spring-loaded latch. It has a bevel on its closing-direction side, which interacts with the door opener latch when the door is closed, in such a way that the latch can pass the door opener latch as the door is moved into the closed position. In doing so, the latch is forced over, i.e., pulled into the lock against its return spring.

[0040] Regarding the structure and functions of the connection device designed as assembly 20, the following applies: In the illustrated embodiment, assembly 20 is arranged on an end face of the door opener housing 2. It forms part of the end face 2s of the door opener housing.

[0041] As already mentioned, assembly group 20 comprises the following three components: a first terminal block 21 as a housing-mounted terminal block, a second terminal block 22 as a movable terminal block, a printed circuit board 23 designed as a circuit board which is connected to the stationary first terminal block 21 in a movement-resistant manner.

[0042] Regarding the structure of the printed circuit board 23: The printed circuit board has two conductor tracks 23y, each of which is electrically connected to an associated insulation displacement connector 23sk. The insulation displacement connectors 23sk are permanently attached to the printed circuit board 23 and protrude beyond the plane of the printed circuit board. The printed circuit board is connected to the coil of the electrically switchable locking device 3 via coil wires 3x. The coil wires 3x are connected to the associated conductor tracks 23y via corresponding coil terminals 23ax.

[0043] Regarding the first terminal block 21, which is fixedly mounted in the door opener housing 2, preferably in one or more mounting grooves and / or detents: This first terminal block 21 is fixedly mounted in the housing. The circuit board 23 is connected to the first terminal block 21 via pins 21z in a movement-resistant manner. The first terminal block 21 forms part of the door opener housing 2, which in this case has a cuboid basic configuration. The circuit board 23 is – as already mentioned – part of an end wall 2s of the door opener housing. In the illustrated case, the first terminal block 21 is fastened in the housing on one side in conjunction with the rear housing wall adjacent to the terminal block 21 and on the other side in conjunction with the front housing block adjacent to the terminal block 21.Regarding the second terminal block 22, which is designed as a movable terminal block: This second terminal block 22 acts as a movable plunger that interacts with the insulation displacement connectors 23sk of the circuit board 23 to establish and / or release the insulation displacement contacts between the connecting cables 20x and the insulation displacement connectors 23sk. This interaction occurs when the movable terminal block 22 is moved upwards, as shown in the figures, via its actuating end 22b, which engages at its bottom end. This is a sliding movement in which the two plunger-like holders 22h of the terminal block 22 are linearly guided and moved within complementary receiving spaces, which are designed inside the fixed terminal block 21 as shaft-like receiving and guide spaces. The contact position is maintained as an insulation displacement contact between the connecting cables 20x and the insulation displacement connectors 23sk.At the upper end of the stamp-like holders 22h, receiving and / or support devices 22ax are formed in which the connecting cables 20x are inserted, so that when the terminal block 22 is pushed upwards, the connecting cables held in the holders 22h are carried along and come into cutting contact with the cutting terminals 23sk in the upper position.

[0044] In the Figuren 2a , 2b and 2c The connection process is shown. Fig. 2a The movable clamping block 22 is in its lower position, i.e., position 1 as the assembly position. In this position, the connecting cables 20x can be inserted through the inlet openings 21 dx in the first fixed clamping block 21. The inlet openings are designed as through holes such that the connecting cables can be inserted into the respective receiving and guide chamber and thereby into the receiving and / or support device 22ax at the upper end of the punch-like holders 22h of the movable clamping block 22. This assembly position with inserted connecting cables 20x is described in Fig. 2b shown.

[0045] In Fig. 2c The contact position, i.e., the operating position, is shown in which the insulation displacement connection between the insulation displacement terminals 22sk and the connecting cables 20x is formed and held. In this position, the terminal block 22 is shifted upwards to its upper position, in which the insulation displacement connection is formed. The terminal block 22 can be locked in this position, e.g., by a detent.

[0046] As can be seen particularly from the Figuren 1 , 2 combined with Fig. 3a As can be seen, two through-holes 21d are formed in the upper area of ​​the terminal block 21. These are through-holes. Contact pads 23p are formed on the circuit board 23, aligned with the through-holes. For electrical testing during manufacturing, contact pins are inserted through the through-holes 21d until their free end comes into contact with the contact pads 23p, thereby energizing the associated conductor tracks 23y, which in turn energizes the coil 3sp connected via the coil wires 3x. In this context, reference should be made to the Fig. 3bb , in which the conductor tracks in circuit board 23b are shown. The connection of the coil via the coil wires 3x is best in Fig. 4b to be seen. Reference symbol list
