Definitions
- the present invention relates to a plug connector with a plug part with at least one contact pin and a mating plug part with at least one contact socket, which are guided in insulating bodies and which have positioning means that correspond to one another in the insertion direction and corresponding guide means, the guide means of the plug part or mating plug part having a guide section, which interacts with a counter-guiding section of the counter-connector part or the plug part in such a way that the plug part and the counter-connector part are brought together relative to one another during the plugging process in order to achieve the corresponding position of the guide means.
- Such a connector is known from DE 20 2007 017 521 U1.
- This is a single-pole connector, especially for photovoltaic connections, which is intended to improve the blind mating of plug and socket.
- two inclined insertion surfaces surrounding the contact carrier are provided with corresponding mating inclined surfaces, which position the plug part and the mating plug part against one another.
- US Pat. No. 9,397,434 B2 discloses, in a sleeve-shaped plug part, an inclined guide surface which is arranged on the inner circumference of the sleeve and which partially surrounds the mating plug part after it has been inserted.
- a longitudinally extending latching web arranged on the circumference of the mating connector part moves along the guide surface during the introduction of the mating connector part into the connector part and reaches a suitable latching opening at the lowest point of the guide surface, so that the mating connector and mating connector part are clearly positioned relative to one another.
- Both variants represent possibilities of merging the plug-in connection in the exact desired position without looking closely at the plug-in connector, i.e. blindly.
- the present invention is based on the object of proposing a further possibility for designing a plug connector with a plug part and a mating plug part as well as positioning means and guide means, which enables blind mating of the plug connector regardless of the pin configuration and at the same time allows different configurations and applications.
- the guide section is designed as an inclined surface in the plug part and the mating plug part.
- This inclined surface runs from a lowest point of the plug part or mating plug part to a highest point and thus forms, for example, a more or less inclined cutting surface to the longitudinal axis of the connector where the plug part and mating plug part touch in the contacted state.
- the inclined surface forms either the mutually corresponding end faces of each contact carrier in the plug part and mating plug part or the end face facing one another of a guide sleeve in the plug part or mating connector part that protrudes beyond the insulating body in the axial direction and form a corresponding shoulder running around the insulating body of the mating plug part or the plug part.
- the sloping surface forms the entire end face of the insulating body as a guide surface
- the guide sleeve of the plug part or mating plug part encompasses the insulating body of the mating plug part or plug part, so that the guide surface and mating guide surface positioned in relation to one another revolve gene connector part or connector part.
- the guide sleeve is designed in such a way that it surrounds contact pins protruding from the insulating body.
- the guide section and the counter-guide section face each other and are positioned. Both variants are based on the sloping surface as the guide section, with the sloping surface being designed as a solid surface in the first case and only as a narrow edge surface in the second case. Furthermore, on the connector according to the invention there is a locking pin or a corresponding locking opening at the lowest or highest point of the inclined surface of the mating connector part or connector part as positioning means at the highest or lowest point of the inclined surface of the mating connector part or mating connector part. The locking pin and the locking opening extend in the longitudinal direction of the plug part and mating plug part.
- the sloping surfaces serve to bring the connector and mating connector together in a self-adjusting manner due to the guidance on the sloping surface. Because the latching pin protrudes beyond the at least one contact pin, it is ensured that the contacts of the plug part do not touch the end face of the mating plug part and are damaged as a result. Once the detent pin reaches the detent opening, the contacts are engaged with the contact sockets in the desired position.
- the contour of the inclined surface means that the connector part and mating connector part are rotationally aligned with one another and blind mating is significantly improved. In addition, this prevents the plug part from being rotated too much about its longitudinal axis by a fitter when searching.
- the plug connector according to the invention thus has a self-adjusting plug part and mating plug part with a specially designed stick face, with the plug part alone being able to be oriented into the correct position during plugging.
- the sloping surface has an inclination of 10° to 80° relative to the longitudinal direction of the connector part and mating connector part, particularly good guidance being provided at an inclination exceeding 45°.
- the profile of the sloping surface is arcuate from the lowest to the highest point, which particularly preferably corresponds to the profile of a thread.
- the sloping surface can thus have a spiral and/or sloping contour which rotationally aligns the connector part and the mating connector part with respect to one another.
- the locking pin and the at least one contact pin are resiliently mounted in the axial direction.
- the locking pin and the at least one contact pin are sunk in the axial direction into the plug part or mating plug part, so that the inclined surfaces of the plug part and mating plug part touch. Due to the configuration of the inclined surfaces, when they are plugged together, the entire alignment takes place via the spiral-shaped and/or inclined geometry of the inclined surfaces.
- the locking pin can dip into the provided locking opening due to the relaxing spring mounting.
- the at least one contact pin which can be moved in the axial direction together with the locking pin and thus also dips into the corresponding at least one socket.
- the latching pin and the at least one contact pin are not fully immersed in the plug part and still protrude somewhat, which can possibly happen, for example, when plugging together slowly.
- the assembler rotates the plug part or mating plug part "with" the helical geometry in the same direction, the forces are very small and the spring is not compressed. In this case, the guide then takes place exclusively via the protruding locking pin in the manner described above without springing.
- This special design of the connector according to the invention makes it easy to identify because of its shape, and these features can be implemented in all locking devices in the form of snap hooks, push-pull or screw connections with a thread in all sizes and any pole configuration.
- the arrangement of the locking pin can be implemented both in the plug part and in the mating plug part.
- the snap-in opening then corresponds to the other part of the connector.
- the guide sleeve can also be provided in the plug part or the mating plug part.
