Definitions
- the invention relates to a retraction aid of electrical connectors with a displacement direction in the insertion direction, more precisely a connector, which consists of a connector and a mating connector, which can be mated together to the connector, with a retraction aid, which is arranged on a part of the connector and with a further part cooperates on the mating connector, according to the features of the preamble of claim 1.
- plug connections which consists of a connector (also referred to as pin header) and a mating connector (with a housing), which can be mated together to the connector. Since this often quite high forces for the mating process are required, feeding aids have become known.
- a pulling-in aid for example, a lever which is arranged on a part of the connector and cooperates with a further part of the mating connector. Although such a lever can be operated well, but it is off the connector before the connector and the mating connector have been put together, so this space, which is often not available, is needed
- the invention is therefore based on the object to improve a retraction aid for a connector to the effect that less space is claimed.
- the connector and the mating connector have a retraction aid, said retraction aid automatically in the insertion direction, d. H. when mating connector and mating connector is pressed.
- the retraction aid thus acts in the axial plug-in direction of the plug connection, so that it hardly needs any space and is also actuated automatically when mating connector and mating connector.
- the plug connector has a guide geometry, wherein an intake lever which can be actuated during mating is arranged on the mating plug connector and which cooperates with the guide geometry as intake aid. Due to the interaction of the feed lever on the mating connector with the guide geometry of the connector, the retracting aid is actuated by the axial actuation of the mating connector in the direction of the connector (or vice versa). Due to the leverage of the feed lever, low forces during mating are sufficient to assist the process of mating by means of the pull-in aid. This is particularly advantageous if the connector and the associated mating connector has a large number of contact partners to be connected. Moreover, it is not necessary in this case to optimize the frictional engagement between the connector and mating connector, since the frictional forces due to the lever-like magnification when pressing the retraction aid only a minor role
- the mating connector is formed by an inner housing and an axially displaceable outer housing. By the axial sliding operation of the outer housing relative to the inner housing, the operation of the retraction aid is performed.
- Other levers or the like, which are arranged in the prior art outside of the mating connector as retraction aid, can be omitted, so that an axial retraction aid is realized by the concentric structure of the mating connector, which saves considerable space.
- the guide geometry has two webs running parallel and forming a guide groove.
- a pin arranged at its end are introduced and guided in a targeted manner during the process of mating.
- a targeted influencing of the lever action of the intake lever is effected in a further embodiment of the invention in that the two webs have in their one end region a crosspiece connecting them.
- the cross bar thus an end stop for the movement of the feed lever, in particular its current in the guide pin, realized. This is a stop for the movement of the intake aid given.
- the first part of the course of the webs in their insertion region for the intake lever causes a recording of the part of the retraction aid, which is arranged on the mating connector.
- the further course of the webs then causes a targeted deflection of the feed lever together with the bend in the guide, so as to cause the leverage of the rotatably mounted on the mating connector feed lever.
- more than one bend can be provided. Instead of at least one bend, it is also conceivable to realize the webs on the connector so that an arcuate course of the guide groove results.
- the invention provides that the retraction lever is arranged via a pivot point on the mating connector, in particular its inner housing, and in each case has a pin in its two end regions. Due to the arrangement of the feed lever via a pivot point on the mating connector thus the leverage is realized.
- the two arranged at its end pins make the operative connection on the one hand to the mating connector and on the other hand to the connector.
- FIGS. 1 to 5 An intake aid according to the invention is shown in FIGS. 1 to 5.
- Figure 1 shows a connector 1 in not yet mated condition of connector 2 (pin header) and mating connector 3 (with housing). It can be seen that on the connector 1 a Einzugs Anlagengeometrie and a Verrastgeometrie are present. These geometries act together with a retractable in the insertion direction retraction aid on the housing and a cooperating latching element.
- the mating connector 3 is formed by an inner housing 4 and an outer housing 5. These two parts are concentric with each other and axially displaceable relative to each other.
- a pull-in geometry 6 is arranged, which cooperates with a feed lever 7, which is arranged on the mating connector 3, in particular its inner housing 4.
- the mating connector 3, in particular its outer casing 5, a latching hook 9 and the connector 2 have a survey 10.
- FIG. 1 shows very clearly that the plug-in connector 2 has not yet been plugged into the mating connector 3.
- the inner housing 4 and the outer housing 5 are in their extended position, from which it is possible, the outer housing 5 to the left in the direction of
- Inner housing 4 to move (when viewing Figure 1), so that the inner housing 4 is almost completely immersed in the outer housing 5.
- FIG. 2 shows in the left-hand illustration a prefacing position in which the mating connector 3 has been inserted into the plug-in connector 2 to some extent. Only when reaching the Vorsteckposition the retraction aid of the housing can be moved in the direction of insertion. For this purpose, the locking hook 9 is released by the pin header (connector 2) at this position. This latching hook 9, which cooperates with the survey 10 of the connector 2, may be present, but need not.
- the guide geometry 6 is formed by two parallel webs 12, 13 which have at their one end a transverse web 14 which forms a stop. Opposite this end, the guide geometry 6 is open, so that an element of the retraction aid, which is arranged on the mating connector 3, can be inserted into a guide groove 15 formed by the two webs 12, 13 and is selectively guided during the mating operation.
- the mating connector 3 has an elongated guide groove 16, which is arranged in the outer housing 5 in this embodiment.
- the retracting aid 7 each have a pin 18, 19.
- the intake lever 7 in its axial course on an angled portion 20, which is guided by a recess 21 of the mating connector 3, in particular its inner housing 4.
- FIG. 3 analogously to FIG. 1, it is shown that the individual elements of the plug connection 1 are prepared for the mating operation.
- the connector 2 is not yet plugged into the mating connector 3.
- Inner housing 4 and outer housing 5 of the mating connector 3 are pulled apart, so that a positional fixing of the outer housing 5 is given on the inner housing 4, however, a further axial collapse of the outer housing 5 relative to the inner housing 4 is possible. This means that in this collapse, the inner housing 4 concentric almost completely immersed in the outer housing 5 of the mating connector 3.
- FIG. 4 shows, analogously to FIG. 2, the so-called pre-insertion position.
- the connector 2 has been used a little way into the inner housing 4, including on the inside of the inner housing 4, an elongated axial recess (in the form of a groove) is present, which allows the survey 10 immersing the connector 2 in the Inner housing 4 not hindered.
- the Vorsteckposition according to Figure 4 or according to Figure 2
- the pin 19 of the feed lever 7 comes in the free area of the guide geometry 6.
- the connector 2 has been used a little way into the inner housing 4, including on the inside of the inner housing 4, an elongated axial recess (in the form of a groove) is present, which allows the survey 10 immersing the connector 2 in the Inner housing 4 not hindered.
- the outer housing 5 of the mating connector 3 is axially displaced by manual operation on the inner housing 4, so that by means of the feed lever 7 and the corresponding interaction of its pins 18, 19 with the pull-in geometry 6 on the one hand and the guide geometry 8 on the other hand, the retraction aid is actuated.
- Feeding lever 7 has arrived at the end region of the guide groove 15 in the region of a stop forming transverse web 14.
- the free end of the latching hook 9 is raised from the survey 10 of the connector 2, so that it is possible that the connector 2 may first dip a bit further into the inner housing 4, so that the pin 19 in the straight , parallel to the longitudinal axis of the connector 2 extending insertion region of the guide geometry 6 can dive. As long as this is the case, the intake aid still has no effect. The retraction aid is only then actuated by the outer housing 5 being subsequently pushed over the inner housing 4 by external manual actuation, starting from this prefastening position.
