DETAILED DESCRIPTION

[0045] FIG. 1 shows a perspective view of a plug connector 1 for a plug connection according to the invention. Plug connector 1 includes an insulating housing 4, insulating housing 4 having four conductor insertion openings 4a for guiding an electrical conductor into the insulating housing 4. FIGS. 6a and 6b each show a side sectional view of a specific embodiment of a plug connector 1. A possible inner structure of the plug connector is clear from FIGS. 6a and 6b.

[0046] A contact insert 5 is received in insulating housing 4, contact insert 5 having a busbar 5a and a clamping spring 5b. Busbar 5a and clamping spring 5b form a first clamping point 6 for the electrical conductor. Insulating housing 4 further has a contact pin receiving opening 4b for guiding a contact pin 8 into insulating housing 4, busbar 5a having a second clamping point 7 for contact pin 8. The second clamping point may be formed, for example, by a further clamping spring. However, it is also conceivable that clamping spring 5b for first clamping point 6 is also designed in such a way that, with its free ends, it forms first clamping point 6 and second clamping point 7 with busbar 5a. Insulating housing 4 has four contact pin receiving openings 4b for guiding a contact pin 8 to second clamping point 7 in insulating housing 4. Contact pin receiving openings 4b and conductor insertion openings 4a are arranged on opposite sides of insulating housing 4.

[0047] It is clear from the combined examination of FIGS. 1, 6a, and 6b that plug connector 1 has an actuating element 9, actuating element 9 being configured to open and/or close first clamping point 6. Actuating element 9 is designed as an actuating lever 9a, actuating lever 9a being supported on insulating housing 4, pivotable around a pivot axis. Actuating lever 9a has an operating section, with the aid of which the user may manually pivot actuating lever 9a. Actuating lever 9a also has an actuating section 9b, actuating section 9b interacting with a clamping leg of clamping spring 5b in such a way that it opens and/or closes first clamping point 6 by pivoting the operating section.

[0048] FIG. 2a shows a perspective view of a plug socket 2 for a plug connection according to the invention. FIG. 2b shows a cutaway side view of plug socket 2 according to FIG. 2a. Plug socket 2 has insulating walls 10 and contact pins 8, for example a plug connector 1 according to FIGS. 1, 6a, and 6b being able to be plugged into plug socket 2, and contact pins 8 being able to electrically conductively contact busbar 5a of plug connector 1 through contact pin receiving opening 4b.

[0049] It is clear that insulating walls 10 form a receiving opening 10a and a receiving space for plug connector 1 connected thereto. Plug connector 1 would then be limited by insulating walls 10 in this exemplary embodiment. Due to insulating walls 10, receiving opening 10a is designed as a receiving opening 10a open on one side. Plug connector 1 may thus be inserted into plug socket 2 only via one side.

[0050] It is also apparent that a projection 12 is arranged on the inside of plug socket 2. This projection 12 may be designed, for example, as a cam. A plugged-in plug connector 1 may be secured by this projection 12 against being pulled out unintentionally. Projection 12, or the cam, is used as a latching connection, which latches plug connector 1 with respect to plug socket 2.

[0051] FIG. 3 shows a plug connection according to the invention, made up of plug connector 1 according to FIG. 1 and the plug socket according to FIGS. 2a through 2b. It is clear that an actuation of actuating lever 9a is blocked by insulating walls 10 in an assembled state of plug connector 1 and plug socket 2. A deflection of the actuating section of actuating lever 9a is not possible, since actuating lever 9a is mechanically blocked by one of insulating walls 10.

[0052] FIG. 4 shows the plug connection according to the invention according to FIG. 3 on a circuit board 3. The easy mounting of the plug connection via contact pins 8 of contact socket 2 is clear.

[0053] FIG. 5 shows a plug connection according to the invention unit in a second specific embodiment. In contrast to the specific embodiment according to FIGS. 3 and 4, two eyelets 11 are arranged on plug socket 2 of the plug connection. In this exemplary embodiment, eyelets 11 are arranged on two opposite side walls 10 in the area of receiving opening 10a, the eyelets extending past plugged-in plug connector 1. For example, a closure element or a seal may be mounted via eyelets 11.

[0054] This has the advantage that plug connector 1 is unable to be removed from plug socket 2 without detaching the closure element or the seal beforehand. For example, a rod may be used as the closure element, which is guided through both eyelets 11 and is secured with the aid of a screw connection. However, other latching connections, for example, are also conceivable. An unintentional removal of the plug connector may be prevented in this way.

[0055] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
