Description

The invention relates to a set of a connector and a holding element, wherein the connector has a Isolierstoffgehäuse and the connector and the holding element are designed for locking with each other. The retaining element has latching elements projecting from a bearing surface of the retaining element.

The invention further relates to a connector and a retaining element for this purpose.

DE 203 18 084 U1 discloses a strain relief device for the connection lines of a connector in the form of a cable holder, which can be plugged into corresponding receptacles of a connector and optionally latched there.

DE 10 2010 010 259 B1 discloses a connector with an insulating housing and with a separate strain relief. The strain relief element has at its free end projecting locking elements, which dive into associated grooves of the connection side of the connector and lock behind a cross bar with the connector. For this purpose protrude locking projections of the locking elements in the groove behind the crossbar of the connector and together with the crossbar form a handshake, which prevents removal of the strain relief from the connector.

Proceeding from this, it is an object of the present invention to provide an improved set of connector and retaining element and a corresponding connector and an associated retaining element.

The object is achieved by the set with the features of claim 1 and with the connector with the features of claim 14 and the holding element with the Characteristics of claim 23 solved. Advantageous embodiments are described in the subclaims.

It is proposed that the connector on a Anrastfläche has a plurality of detent openings, which have a Einsteckbereich for receiving in each case one in a perpendicular to the Anrastfläche aligned immersion direction in the insertion region inserted locking element and an adjacent detent region. The latching region has a latching edge for positive latching of a latching element of the holding element and on the Anrastfläche a smaller opening than the Einsteckbereich to lock according to a transversely to the dipping direction relative transverse displacement of the holding element and connector to each other inserted into the plug-in locking element in the latching area with the locking edge ,

Thus, the support member is placed in a vertical movement perpendicular to the Anrastfläche with its bearing surface on the Anrastfläche so that the locking elements in the sufficiently wide open insertion region of the associated detent openings dive. Then takes place in a position in which the holding element rests on the connector, a transverse displacement to move the locking elements from the insertion in the adjacent latching area and there to lock each at an associated locking edge. In this way, at least one positive stop for the locking elements is formed, with which the retaining element is secured to the connector.

The detent opening is an opening or depression in the insulating housing of the connector on the Anrastfläche, which is divided into two merging areas, the insertion and the catch area, both of which open at the common Anrastfläche.

Such a set is very compact and simple and provides a reliable connection of the holding element to the connector ready. Handling for mounting is very easy in two steps by attaching the retaining element the connector for inserting the locking elements in the latching openings and then lateral displacement of the holding element relative to the connector possible.

For the purposes of the present invention, the indefinite term "a" is to be understood as such and not as a number word. Thus, additional elements are not excluded, such as a multi-part.

The insulator housing of the connector may have juxtaposed conductor insertion openings extending in a conductor insertion direction into the insulator housing to conductor terminals in the insulator housing. The Anrastfläche of the connector may be the surface of the connector, in which the latching openings are introduced and which is parallel to the plane which is spanned by the arrangement direction of the juxtaposed conductor insertion openings and by the Leiterereinsteckrichtung, or parallel to a plugging direction of the connector. Thus, the support plate is aligned parallel to the plane of a bundle of electrical conductors which are plugged into the connector. In this way, the latching of the retaining element is adapted to the connector to the force of the clamped electrical conductors.

The insertion region and the latching region of a latching opening of the connector can lie next to one another in the direction of arrangement of the conductor connection terminals. Thus, for latching of the holding element to the connector, a transverse displacement of the holding element in a direction transverse to the extension direction of the clamped electrical conductors. If the holding element is used as a strain relief element, then a force is exerted by a tensile force of the electrical conductor to the strain relief element, which is transverse to the locking direction of the holding element on the connector. Thus, the secure locking of the retaining element is not affected on the connector.

A first group of latch openings of the connector may be arranged side by side in a first row. Furthermore, at least one second detent opening can be arranged at a distance from this first row. The detent openings The first group in the first row then act together with the at least one further latching opening, which lies outside the first row, so that a tilt-proof latching is achieved.

It is conceivable that a second group of latching openings in a second row is arranged side by side, wherein the second row is spaced from the first row. There may also be more than two rows of groups of detent openings, such as three or four rows. Thus, the lock can be distributed on the Anrastfläche and the power flow can be made uniform.

It is conceivable that the at least one second latching opening are arranged offset to the latching openings of the first group with respect to the plugging direction and / or the conductor plugging direction. Such an offset of the latching openings arranged in the adjacent rows counteracts excessive weakening of the material of the insulating material and improves the flow of force in the locking of the retaining element on the plug connector.

The latching elements of the holding element can be designed as a latching hook with a holding arm extending away from a base surface of the holding element and a latching projection projecting from the holding arm. Such a latching hook can then dip with its locking projection in the correspondingly large opening of the insertion. In the transverse displacement of the latching hook in the latching area then a positive connection between the latching projection and the latching edge of the latching area is formed. For this purpose, the latching projection is pushed under the latching edge. The latching hook can in this case e.g. have an L-shaped contour.

The latching projection of a first group of latching elements can point in a first direction. The latching projection of at least one further latching element can then point in a direction opposite to the first direction. Thus, at least two facing in opposite directions latching hooks form a complementary pair of locking elements which act in the opposite direction or improve the locking of the retaining element to the connector.

The connector can be multi-part. The holding element can then be designed for the positive connection of the plurality of insulating material of the connector. Thus, the latchable on the connector holding element can be used to connect the insulating material together and prevent falling apart of the insulating material. The retaining element thus forms a clip connecting the Isolierstoffgehäuseteile.

However, the retaining element can also be designed to connect two plugged connectors to prevent unintentional removal of the connectors from each other. For this purpose, a set of first and second connector has a latchable with these two connectors holding element.

The retaining element may be a strain relief element with a projecting platform of the connector with fastening contours for fastening an electrical line. The plugged into the connector electrical conductors can be secured, for example. With cable ties to the platform of the holding element. If a tensile force is exerted on the electrical conductors, this is intercepted by the holding element and transferred via the latching connection of the holding element with the connector on this total.

The connector and the retaining element may have securing structures which prevent or complicate a transverse displacement of the retaining element for movement of the locking elements of the retaining element from the latching region of the locking openings of the connector out into the insertion by positive engagement or frictional engagement. In order for a further locking of the retaining element is provided on the connector on the latching with the dipping into the locking openings locking elements addition. Such securing contours can be formed from at least one pair of locking nubs and an associated locking recess. In the latched state, in which the latching elements are locked in the latching areas of the latching openings, such a locking knob plunges into an associated latching recess and prevents a transverse displacement back into the unlocked state. For this would have such a large force be spent, which allows the sliding out of the locking knob out of the locking recess out.

The width of the detent openings can be adapted to a whole pitch. The insertion area and the latching area are then each adapted to a half pitch. An entire pitch corresponds to the distance of adjacent conductor insertion openings from each other. This is used according to the pitch width of the connector for each Leitereinstecköffnung a customized latching opening. The retaining element must be transversely displaced by only half a pitch width after placement on the connector. The width of the latching openings can here correspond to half the pitch. But it can also be a bit narrower, e.g. 90% of the pitch width, so as not to unduly weaken the insulator housing.

The width of the detent openings can also be adapted to half a pitch. The insertion area and the rest area are then each adapted to a quarter pitch. Other widths of the latching openings and other width ratios between plug-in area and latching area are conceivable. However, if possible, the width of the insertion region and the latching region should each be half the width of the latching opening.

The retaining element only has to be displaced by a relatively small distance, which is smaller than a pitch.

The formation of the latching opening with a half pitch width for the insertion area and a half pitch width for the latching area has a very even force application over the entire width of the connector in a double row arrangement of groups of detent openings, which are arranged alternately offset from one another.

A corresponding solution in which the introduction of force is even more uniform, offers the division of the detent openings with a width of a quarter of a pitch for the insertion area and a quarter pitch for the latching area with four rows, the latching openings are arranged alternately offset from one another.

The latching openings of the connector provide the ability to accommodate different types of support elements, such as. Mounting adapter, locking elements, locking feet, shielding plates, etc.

A continuous receiving groove is avoided by the detent openings, so that the air and creepage distances are not reduced too much on the latching surface of the connector.

For the purposes of the present invention, the indefinite term "a" is to be understood as such and not as a number word. Thus, additional elements and a multi-parting are not excluded, even if this fact in the individual case by "at least one" is particularly highlighted.

FIG. 1 shows a perspective view of a set of a connector 1 and a holding element 2. The holding element 2 is designed as a strain relief and has a protruding from the connector 1 platform 3 with fastening contours 4 in the form of openings and notches with which, for example, cable ties can be connected to the platform 3. This makes it possible electrical conductors (not shown), which are inserted into the connector 1, to fix the platform 3.

The connector 1 has an insulating material 5. This is executed in several parts in the illustrated embodiment and consists of several Isolierstoffgehäuseteilen, which are stuck together. At the conductor insertion side, the connector 1 has a plurality of conductor insertion openings 6 arranged side by side in a row, leading to conductor terminals in the interior of the insulating case 5 to clamp electrical conductors inserted into the conductor insertion holes 6 to the connector 1. Opposite the conductor insertion side, a plug contour 7 of the insulating housing 5 is provided with plug contacts arranged therein.

Also visible are actuation openings 8 on the conductor insertion side above the respective conductor insertion openings 6. These each lead to a conductor connection terminal and are provided and suitable for opening a spring terminal connection in the interior of the connector 1 by insertion of an actuation tool.

It is clear that the holding element 2 is supported on the underside of the connector 1. This underside of the connector 1 forms the Anrastfläche of the connector 1. There are latching openings 10 a, 10 b exist, dip into the locking elements 11 of the support member 2 to lock the support member 2 to the connector 1.

The locking elements 11 of the retaining element 2 are designed as latching hooks with an L-shaped contour.

FIG. 2a ) shows a perspective view of the connector 1 from FIG. 1 with a view of the locking surface 9. There are three latching openings 10a in two rows each, 10b arranged side by side. The latching openings 10a, 10b have a plug-in area 12 and an adjacent latching area 13. The latching area 13 merges into the plug-in area 12, so that a continuous connection is present. The opening at the stop surface 9 opening cross-section of the locking portion 13 is smaller than the opening on the Anrastfläche 9 opening cross section of the insertion 12. This is due to the fact that a locking edge 14 projects in the form of a web in the locking opening 10a, 10b in the region of the locking portion 13. This locking edge 14 forms a stop for the locking element 11 of the retaining element. 2

It can be seen that the outer detent opening 10b of the second row of detent openings 10a, which is closer to the mating side than to the conductor mating side, is reduced to the detent area 13. The insertion region 12 is not required there, since the latching element 11 can first be positioned laterally next to the side wall of the connector 1, in order then to be pushed into the latching region 13.

FIG. 2b ) shows the connector 1 off FIG. 2a ) facing the other side. There, it is clear that the latching edge 14 projects into the latching opening 10a, 10b, wherein below the web-like latching edge 14, a free space remains.

It can also be seen that the insertion region 12 of the latching opening 10a, 10b has the same length (i.e., transverse displacement path) as the latching region 13, but by a greater width in the size of the latching edge 14. Thus, the cross section of the orifice in the insertion region 12 is greater than in the latching region 13.

It is also clear that the width of a detent opening 10a, 10b corresponds approximately to a pitch width. An entire pitch width is the distance of the center axes of two adjacent conductor insertion openings 6 from each other. The width of the insertion region 12 and the latching region 13 corresponds in each case to approximately half the width of the division.

It can also be seen that between the latching openings 10a, 10b of two adjacent poles of the connector 1, each pole of a connector 1 is assigned a Leiterereinstecköffnung 6 for insertion of an electrical conductor, not shown, each a web 18 remains, which you Rast openings 10a, 10b adjacent Pole separates from each other. The web 18 is flush with the Anrastfläche 9 and provides a sufficient clearance and creepage distance between the poles associated insulating housing parts of the connector 1 safe.

The latching openings 10a, 10b arranged in the two rows are alternately offset relative to one another, so that in the insertion direction L, for example, a latching opening 10a of the first row is followed by a latching area 13 of a latching opening 10b of the second row. Correspondingly, the latching openings 10a of the first row, which is closer to the conductor insertion openings 6, are transversely offset by a half pitch width from the behind the latching openings 10b of the second row, which is closer to the plug-in terminals 7.

FIG. 3a ) shows a perspective view of the holding element 2 in the form of a strain relief FIG. 1 , It is clear that the holding element 2 is plate-shaped and is a platform 3 with the formed as openings and lateral incisions or hollows fastening contours at the free end. The holding element 2 has a support surface 15 from which the latching elements 11 protrude in a common direction. The latching elements 11 are designed as latching hooks, each with an integrally formed with the support surface 15 hook arm 16 and a transversely projecting locking projection 17 thereof.

It can also be seen that the locking elements 11 are arranged in groups in two rows. The locking elements 11 of a group are lined up in an alignment with a distance next to each other. The rows are aligned transversely to the longitudinal direction of the support member 2 and spaced apart in the longitudinal direction of the support member 2 and arranged parallel to each other or aligned.

It is also clear that the locking elements 11 of the first group protrude in the first row with their locking projection 17 in a direction away from the locking elements 11 of the second row direction. The same applies to the locking projections 17 of the locking elements 11 of the second group. The latching projections 17 of the first group of latching elements 11 thus have in a first direction and the latching projections 17 of the latching elements 11 of the second group in a direction opposite to the first direction. In this case, the locking lugs 17 in this embodiment away from each other. Alternatively, however, they can also be oriented toward each other.

It can also be seen that the latching elements 11 are offset from one another alternately from the first row to the second row. The locking elements 11 of the second row are thus in the alignment transverse to the direction of arrangement of the respective group seen in the space between the locking elements 11 of the other group.

FIG. 3b ) shows a holding element 2, which has no platform 3 and is provided only as a connecting element for connecting a multi-part connector 1. Here it is once again clearer that the groupwise in each case arranged in a row locking elements 11 are alternately offset from a first row to the second row and vice versa. The holding element 2 according to the FIG. 3b ) may be provided for attachment to a surface of a printed circuit board or other substrate, for example by means of gluing or not shown by other fasteners, for example. Detent means, on the surface facing away from the surface with the locking elements 11. Furthermore, it is conceivable that the holding element 2 on the surface facing away from the surface with the locking elements 11 has a latching contour for latching onto a mounting rail.

It is also clear that the latching elements 11 are formed as L-shaped latching hooks with a protruding from the support surface 15 hook arm 16 and in each case a transversely projecting from the free end of the hook arm 16 latching projection 17. Below the locking projection 17 is a free space into which the web-like locking edge 14 of the locking opening 10 a, 10 b of the connector 1 is positioned when the connector is placed on the holding member 2 and moved transversely. With the Retaining lip 17 and the associated locking edge 14 of the connector 1, a positive connection is provided.

It is also clear that the hook arms 16 are formed integrally with the holding element 2, for example, from plastic material. They can taper to the retaining lip 17 or its free end to run, so as to provide a more stable connection to the support surface 15.

As an alternative to the L-shaped contour of the latching elements designed as latching hooks, they could also have a T-shaped or dovetail-shaped contour, in which case the contour of the latching openings 10a, 10b is adapted accordingly.

If the formation of the retaining element 2 as a strain relief according to the FIG. 3a ) is provided with a metallized surface or coating, the retaining element 2 can also be used as a shielding element.

FIG. 4a ) shows a perspective view of a set of connector 1 and the holding element 2 FIG. 3b ) in the pre-lock position. It is clear that the holding element 2 projects on the left side in the viewing direction from the contour of the connector 1 and the connector 1 on the right side with its contour, the holding element 2 protrudes. A latching element 11 of the holding element 2 is positioned laterally next to the connector 1. In this area, the latching opening 10a, 10b of the connector 1 is opened laterally, so that the locking element 11 slides in a transverse displacement of the connector 1 to the left or a transverse displacement of the holding element 2 to the right in this latching opening 10a, 10b and in the latching region 13 located there Locked form is locked.

In FIG. 4b ) is the perspective view of the set FIG. 4a ) in the locked position. It is clear that now the connector 1 and the support member 2 are moved relative to each other transversely to the conductor insertion direction L, so that their contours no longer survive against each other. In this case, the latching element 11 of the holding element 2 is pushed into the latching opening 10 a, 10 b, so that the latching projection 17 of the latching element 11 together with the latching edge 14 of the Connector 1 and the detent opening 10a, 10b form a stop to each other. In this way, the retaining element 2 is positively locked to the connector 1.

FIG. 5 shows a side view of the set FIGS. 4a) and 4b ) With the section line EE in the region of the support surface 15 of the holding element 2 and the adjoining Anrastfläche 9 of the connector 1. It can be seen that protrudes from the support surface 15 of the support member 2 in section L-shaped locking element 11, from the tapered hook arm 16 and the transversely projecting locking projection 17 is formed. It is clear that the latching element 11 is immersed in the latching opening 10a, 10b of the connector 1, which is introduced into the Anrastfläche 9. In the illustrated section, the locking element 11 is in the latching region of the locking opening 10, so that the web-like locking edge 14, which limits the detent opening 10a, 10b in the latching area, engages under the latching projection 17 and is positioned between the latching projection 17 and the support surface 15. Incidentally, the locking element 11 is also positively received in the latching opening 10a, 10b, so that the range of motion between the connector 1 and retaining element 2 is limited. Also conceivable is a receptacle of the locking element 11 in the latching opening 10a, 10b in the latching area with a press fit, so that beyond the positive locking also a frictional connection or at least one frictional connection is provided.

FIG. 6a ) shows the sketch of the set of connector 1 and retaining element 2 of Figure 4a) in the pre-locking position in section EE. In this case, the latching elements 11 can be seen, which are inserted into the insertion region 12 of a latching opening 10a, 10b formed from the insertion region 12 and the adjacent latching region 13. The opening in the insertion region 12, ie the cross section of the opening from the Anrastfläche 9, is at least as large as that of the hook arm 16 and projecting therefrom locking projection 17 spanned perpendicular to the support surface 15 of the retaining element 2 projected area. It can be seen that the retaining element 2 is placed in the pre-locking position offset from the contour of the connector 1 on the insulating material 5. In this case, the holding element 2 with its support surface 15th placed vertically on the Anrastfläche 9 of the connector 1, so that the locking elements 11 immersed in associated latching openings 10a, 10b.

Then there is a transverse displacement of the holding element 2 on the plane of the superimposed Anrastfläche 9 and support surface 15 transversely to the Leiterereinsteckrichtung L.

It becomes clear FIG. 6b ), that the locking elements 11 are now displaced transversely from the insertion region 12 in the adjacent latching region 13. In this case, the web-like latching edge 14, which projects into the respective latching opening 10a, 10b on the plane of the latching surface 9 of the connector 1, engages over the latching projection 17 of the latching element 11 inserted therein. The opening cross section of the latching area 13 is smaller in comparison to the opening cross section of the plugging region 12 corresponds approximately to the cross-sectional area of the hook arm 16 in its height when the locking element 11 is inserted into the latching opening 10a, 10b.

FIG. 7 shows a plan view of the connector 1 on the left side with a view of the Anrastfläche 9 and on the right side with a view of the Anrastfläche 9 opposite upper side of the connector 1. The sectional lines AA and BB are shown.

It can be seen that the latching openings 10a, 10b are arranged in groups in two rows next to one another. These two rows are each aligned transversely to the conductor insertion direction L. In this direction, transverse to the conductor insertion direction L, in addition to an insertion region 12 of the latching openings 10a, 10b, there is a latching region 13 with a smaller opening cross-section.

It is also clear that the latching openings 10a, 10b are alternately offset, so seen in Leiterereinsteckrichtung L in the escape behind a Einsteckbereich 12 a first latching opening 10a, 10b, a latching area 13 follows and vice versa. The transmitted in the form-fitting connection to the insulating material 1 forces are thus distributed over the Anrastfläche 9 at least for the most part evenly.

FIG. 8a ) shows a partial cross-sectional view of the connector 1 in section AA. It is clear that the latching openings 10a, 10b on a sectional plane, for example in section AA, on the one hand an insertion 12 of the locking opening 10a, 10b and in Leiterereinsteckrichtung following a Einsteckbereich 12 with a projecting into the locking opening 10a, 10b web-like locking edge 14 have. Thus, plug-in area 12 and latching area 13 are alternately offset from each other.

In FIG. 8b ) is the partial cross-sectional view of the connector 1 in section BB shown. There is now the locking portion 13 with its locking edge 14 on the left and the insertion portion 12 on the right side. Plug-in area 12 and latching area 13 are thus alternately offset from each other in Leitereinsteckrichtung L and arranged transversely thereto.

FIG. 9a ) shows a partial cross-sectional view of the set of connector 1 and retaining element 2 in section AA. It can now be seen that the cut left latching element 11 of the holding element 2 is in the latching area of a latching opening 10a, 10b.

Also, the right detent element 11, which due to its offset transversely to the Leiterereinsteckrichtung, i. in the direction of view also immersed in a staggered latching region 13 there. Also, this locking element 11 is locked in the latching area 13 by a locking edge 14.
