The door operator is configured to be mounted to a reception body such as a door transom, a wall or the like, and has a connector module for connecting with at least one connecting line. The connector module from a direction of the reception body and from at least one lateral direction, has at least one opening, through which the connecting line can be optionally guided to the connector module. ## Claims ### Claim 1 A door operator configured to operate a swing leaf of a door assembly and to be mounted to a reception body, comprising: a connector module for connecting at least one connecting line, the connector module comprising: a signal connecting circuit board defining a U-shaped circuit board opening communicating with a top side opening of the connector module, the connecting line extending through the top side opening and said U-shaped circuit board opening into the connector module, the circuit board carrying a connecting terminal to which the connecting line is connected, and at least one slip-on recess; and a drive unit to which the connector module is mechanically and self-retainingly connected with at least one slip-on projection inserted into the slip-on recess. ### Claim 2 (depends on 1) The door operator according to claim 1, wherein at least one terminal connector component is arranged in the connector module and configured to establish an electrical connection with another connecting line. ### Claim 3 (depends on 2) The door operator according to claim 2, further comprising a mounting plate, wherein the at least one terminal connector component is fastened to the mounting plate. ### Claim 4 (depends on 2) The door operator according to claim 2, further comprising: at least one distributor circuit board arranged in the connector module and configured for distributing power, provided through the another connecting line, from at least one power supply; and a connecting bridge line that extends from the terminal connector component to the distributor circuit board to establish an electrical connection therebetween. ### Claim 5 (depends on 4) The door operator according to claim 4, further comprising: a cable relief element disposed on the connector module and configured to mechanically receive the connecting bridge line; and at least one clamping element configured to retain the connecting bridge line. ### Claim 6 (depends on 5) The door operator according to claim 5, wherein the cable relief element is adjacent the terminal connector component. ### Claim 7 (depends on 6) The door operator according to claim 6, wherein the cable relief element further comprises one of a T-shaped section and an H-shaped section. ### Claim 8 (depends on 6) The door operator according to claim 6, wherein the cable relief element has a U-shaped section. ### Claim 9 (depends on 5) The door operator according to claim 5, wherein a second clamping element is inserted into a clamping element receiver of the connector module. ### Claim 10 (depends on 2) The door operator according to claim 2, further comprising: a plurality of pilot pins; and a mounting plate, wherein the door operator is mounted to the reception body by the mounting plate and the connector module is positioned on the mounting plate by the plural pilot pins. ### Claim 11 (depends on 10) The door operator according to claim 10, wherein the connector module protrudes beyond the mounting plate. ### Claim 12 (depends on 1) The door operator according to claim 1, wherein the signal connecting circuit board is attached to the connector module by at least one latching element. ### Claim 13 (depends on 12) The door operator according to claim 12, wherein the connector module comprises a support area for supporting the signal connecting circuit board, wherein a portion of the support area is adjacent a support part that is hingedly attached to the connector module. ### Claim 14 (depends on 12) The door operator according to claim 12, wherein the signal connecting circuit board comprises visual indicators. ### Claim 15 (depends on 12) The door operator according to claim 12, wherein the signal connecting circuit board is adapted to be coupled to a flat cable which is guided over the connector module by at least one flat cable guiding element. ### Claim 16 (depends on 1) The door operator according to claim 1, wherein the connector module is self-retainingly connected to the drive unit by a latching element that comprises at least one latching projection. ### Claim 17 (depends on 1) The door operator according to claim 1, wherein the drive unit comprises a shaft passage for receiving a door operator output shaft, wherein the connector module protrudes beyond the shaft passage and has a recess through which the door operator output shaft passes. ### Claim 18 (depends on 17) The door operator according to claim 17, further comprising at least one of a first closure element configured to be inserted into the recess and to thereby form a passage in the connector module for the door operator output shaft, and a second closure element configured to be inserted into the recess and thereby cover the shaft passage.
