Problems solved by technology

[0005] The screwing necessary to achieve the axial fit of the sealing flange 100 is complex and relatively expensive, since an additional threaded hole 104 must be provided and must be sealed by means of a special screw 102
Furthermore, the screwing process is relatively complex, wherein the microencapsulated screw 102 is expensive and its tightness (approximately 2.000 ppm) is not always ensured in the serial production process (Serienprozess)
During the slotting of the bolt 102 metal shavings are produced which can penetrate into the interior of the housing 70 which can later cause damage during operation of the motor or on the circuit board which can lead to failure of the entire motor

Embodiment Construction

[0031] First refer to the following Figure 2 to Figure 8, illustrating a first variant of the fluid-tight motor connection plug 1 according to the invention according to two embodiments. The connecting plug 1 has a plug housing 10 by means of which the connecting plug can be fastened to a housing 70 of the electric machine 7 , for example to a pole housing 70 . At least one electrical line 80 or at least one cable 80 is guided through the connecting plug 1 into the interior of the motor, which is then electrically connected to the electrical conductors in the electrical machine 7 (see Figure 5 ). In this case, the electrical conductors 80 arranged on the connecting plug 1 form together with the connecting plug 1 a mass-produced cable 8 or cable bundle 8 .

[0032] The plug housing 10 is substantially square, has preferably rounded side walls and has a mounting section 11 on its front side, wherein a shoulder is formed on the plug housing 10 at the transition to the mountin...

Abstract

The invention relates to a fluid-sealing electric motor connector (1) for a housing (70) of an electric motor (7), in particular an electric motor (7) of an engine cooling fan or of an ABS / ESP system of a motor vehicle, comprising a connector housing (10), which can be attached to the housing (70) and by means of which at least one electrical line (80) can be connected to the electric motor so as to be fluid-sealed to the electric motor (7), wherein the connector housing (10) can be fastened to the housing (70) by means of a locking spring (50) or a catch mechanism, wherein the fluid-sealing electric motor connector (1) can be fastened to the housing (70) in an easily detachable manner. The invention further relates to a motor, in particular an electric motor (7) for an engine cooling fan or an ABS / ESP system of a motor vehicle, or a completed electrical cable (8) for a motor (7), in particular an electric motor (7), wherein the motor (7) or the completed electrical cable (8) has a fluid-sealing electric motor connector (1) according to the invention.

Description

technical field [0001] The invention relates to a fluid-tight motor connection plug for the housing of an electric motor, in particular a motor cooling fan of a motor vehicle or an ABS / ESP motor. Furthermore, the invention relates to a motor, in particular an electric motor for a motor cooling fan or ABS / ESP of a motor vehicle, or a mass-produced cable for such a motor. Background technique [0002] For cost reasons, deep-drawn parts are used for the housings of electric motors, especially DC motors. In many applications, for example in the motor cooling fan of motor vehicles and / or in the ABS / ESP-area, such electric motors must be made fluid-tight, that is to say the electrical control and supply lines have to be sealed via the sealing flange. Fluid-tight introduction into the motor. The illustration in FIG. 1 shows such a sealing flange 100 according to the prior art, wherein the sealing flange 100 itself passes through an axial seal 105 , and each electrical lead 80 pas...
