Description

Holding frame and plug connector with such a holding frame

Technical Field

The invention relates to a holding frame for a plug connector for receiving a plurality of contact inserts. Furthermore, the invention relates to a plug connector having such a retaining frame.

Background

Such a holding frame serves, for example, for the modular use of contact inserts on a plug connector. One or more contact inserts can be arranged on such a holding frame in order to be inserted together with the holding frame into a housing of a plug connector component or of a plug connector and to be connected to the housing by the holding frame. In this way, the contact inserts can be combined with one another in a modular manner and arranged in or on the plug connector part by means of the retaining frame.

Such a contact insert may have, for example, one or more electrical contacts. In this case, the contact inserts are connected on the one hand to the electrical lines leading to the plug connector and on the other hand form plug contacts, by means of which the plug connector can be brought into mating engagement with the corresponding plug connector part for electrical contact.

Such a modular contact insert offers the advantage of a flexible assemblability and thus a variable usability of the plug connector.

If the contact insert is inserted into the holding frame, it is necessary to hold the contact insert on the holding frame in order to be able to mount the holding frame together with the contact insert, for example, on a plug connector. In the holding frame known from DE 102012110907 a1, for this purpose, a second holding frame part can be attached to the first holding frame part, which has a recess for receiving the projecting element of the contact insert, in order in this way to lock the projecting element placed in the recess and thus to lock it to the holding frame.

In the holding frame disclosed in DE 202012103360U 1, two kinds of recesses are provided on the frame wall. The projecting elements of the contact insert can be pushed in an embedded manner into a first recess in the upper edge of the frame wall, while the pin-shaped formations of the contact insert can be brought into locking engagement with a second recess in the form of an opening.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a holding frame, it can realize the simple insertion of contact insert on holding frame and the reliable locking of contact insert on holding frame, and contact insert can simply be followed holding frame and taken off simultaneously.

According to the invention, this object is solved with the features of the independent claims. Advantageous embodiments and advantageous refinements of the invention are specified in the dependent claims.

The holding frame according to the invention is characterized in that it comprises a base frame having a first side wall, a second side wall opposite the first side wall, a first end wall and a second end wall opposite the first end wall, wherein the first side wall, the second side wall, the first end wall and the second end wall enclose an interior space of the base frame, into which interior space a contact insert can be inserted in the insertion direction. The holding frame is further characterized by a predetermined position element arranged on the first side wall, which has a holding region for each contact insert to be received and which protrudes into a recess formed in the first side wall, and by a cover element mounted pivotably movably on the base frame, which cover element can be transferred into an open position and a closed position, wherein in the closed position the cover element at least partially covers an outer surface of the predetermined position element facing away from the interior.

According to the invention, it is now provided that, when the contact insert is inserted into the holding frame, the contact insert is first inserted into a predetermined positioning element, which is preferably arranged on the base frame on one side, and is held on the positioning element, and then the contact insert is completely fixed on the holding frame by closing the cover element arranged on the base frame. The predetermined bit element is therefore used to form a prepositioning and preferably also a prefixing of the contact insert introduced into the interior of the base frame. For each contact insert to be inserted, the predetermined bit element has a holding region on which the respective contact insert can be held for prepositioning and prefixing. The cover element is arranged on the same side of the base frame as the pre-positioning element, so that the cover element can interact with the pre-positioning element. The cover element is arranged on the base frame in a swingable manner, so that the cover element can function like a side cover of the type provided on the first side wall. By means of the pivoting movement, the cover element can be moved into an open position, in which the contact insert can be introduced into the interior space and can be removed therefrom, and into a closed position, in which the contact insert is fixed in the interior space. The predetermined position element projects into a recess formed on the first side wall, so that the predetermined position element has a gap in the recess, as a result of which the insertion and removal of the contact insert can be facilitated in the open position of the cover element. In the open position of the cover element, the cover element is preferably arranged at a distance, in particular at an angle, from the predetermined position element, so that the predetermined position element has a certain degree of freedom of movement. In the closed position, the cover element covers the predetermined bit element in such a way that the cover element preferably extends parallel to the predetermined bit element. In this way, the cover element can limit the freedom of movement of the prepositioning element in the closed position, so that a reliable fixing of the inserted contact insert can be ensured. Preferably, the cover element covers the predetermined bit element in the region of the gap of the first side wall in the closed position. The cover element can also project into the recess of the first side wall of the base frame like the predetermined positioning element. The cover element is preferably rigid or flexurally rigid. By providing a cover element which can be flush with the first side wall in the closed position, the first side wall preferably has a significantly smaller height relative to the second side wall of the base frame. In the closed position of the cover element, the cover element together with the first side wall may have substantially the same height as the second side wall. The second side wall is preferably rigidly designed and arranged in a fixed position relative to the two end walls, so that the holding frame can be made accessible on one side by means of the predetermined positioning elements and the cover element, which are preferably arranged only on one side of the base frame, whereby the holding frame can be equipped with the contact insert with one hand. The second side wall preferably has a window-shaped opening for each contact insert to be inserted, into which opening one projecting element of the contact insert can be snapped in. When inserting the contact insert, the contact insert can be first secured with its first projecting element in the window-shaped opening of the second side wall and with its second projecting element on the retaining region of the predetermined bit element, and then the cover element can be pivoted from the open position into the closed position, so that an unintentional release of the inserted contact insert from the interior space can be prevented.

In order to enable particularly good and flexible pre-positioning by the pre-positioning element, the pre-positioning element is preferably made of an elastic material, in particular a leaf spring. By means of the elastic design, the predetermined position element can apply or provide a sufficient play when the contact insert is introduced and withdrawn. By means of the elastic design of the positioning element, the positioning element can be elastically deformed or bent during the insertion and extraction of the contact insert, whereby the insertion and extraction of the contact insert can be made significantly easier for the user. The pre-positioning element is therefore preferably not formed to be rigid or resistant to bending, just like the covering element.

Preferably, the pre-positioning element may extend over the entire length of the first side wall. Preferably, the recess of the first side wall into which the projecting element projects at least partially then likewise extends over the entire length of the first side wall. However, it is also possible to provide two or more such predetermined bit elements on the first side wall, which each extend over a partial length of the first side wall. For example, a predetermined bit element can be allocated to each contact insert to be inserted. In this embodiment, it is also possible to form a plurality of recesses in the first side wall, which recesses each extend over a partial length of the first side wall. For example, a vacancy may be provided for each predetermined bit element.

The holding regions of the predetermined bit elements may each be formed as window-shaped openings. In these window-shaped openings, the projecting elements of the contact inserts inserted into the interior of the base frame can be hooked in each case in order to hold them in the interior of the base frame.

In order to fix the predetermined bit element on the base frame, the predetermined bit element can have a fixing section, by means of which the predetermined bit element can at least partially surround the first side wall of the base frame. For this purpose, the fastening section can be bent in a U-shape, for example, so that it can surround or enclose the lower edge of the first side wall of the base frame. By means of the fastening section, the predetermined position element can be pushed onto the first side wall, so that the predetermined position element can be detachably fastened to the first side wall of the base frame.

For further fixing, the fastening section can have at least one latching element, which can be engaged in a latching manner in an opening formed in the first side wall. The latching elements can be configured, for example, in the form of latching lugs or spring tabs. An additional latching connection can be formed between the side wall and the pre-positioning element by means of the latching element. Depending on the length of the fastening section and thus of the predetermined positioning element, a plurality of such stop elements can also be provided on the fastening section, wherein a plurality of such openings, in particular window-shaped openings, can then also be provided on the first side wall.

In order to also be able to fix the contact insert directly or indirectly by means of the cover element, the cover element can have a holding region for each contact insert to be received, wherein in the closed position of the cover element the holding region of the cover element is preferably configured in alignment with the holding region of the predetermined bit element. The contact insert can thereby be fixed and held with its projecting element both on the predetermined bit element and on the covering element.

The holding area of the covering element preferably has the same shape as the holding area of the predetermined bit element. For example, the holding regions of the cover element can each be designed in the form of a window-shaped opening. The projecting element of the contact insert can thus pass through both the holding region of the predetermined bit element, which is designed as a window-shaped opening, and the holding region of the cover element, which is designed as a window-shaped opening.

In order to produce a pivoting movement of the cover element relative to the base frame, a first guide contour and a second guide contour opposite the first guide contour can be formed on the base frame, in which the cover element can be guided when being transferred into the closed position and into the open position. By means of these two guide profiles, a controlled and reliable guidance of the covering element during its oscillating movement is achieved. The two guide contours are preferably designed symmetrically to one another. Preferably, the two guide profiles each have an arc shape. The two guide contours can be formed, for example, in the form of groove-shaped recesses in the base frame. Preferably, the two guide contours are formed on the inner surfaces of the two end walls of the base frame which point in the direction of the interior space.

For guiding the covering element in the two guide profiles, the covering element can have a first guide arm which is guided in the first guide profile and a second guide arm which is guided in the second guide profile. The two guide arms are preferably configured symmetrically to one another. The first guide arm can, for example, be molded on a first lateral side of the covering element and the second guide arm can be molded on a second lateral side of the covering element, wherein the two guide arms extend preferably at right angles out of the main extension plane or out of the longitudinal sides of the covering element.

In order to be able to hold the cover element in a fixed and secure position both in the closed position and in the open position, the two guide profiles can have a first stop region and a second stop region, respectively, wherein the guide arm of the cover element can be inserted in a lockable manner in the first stop region of the two guide profiles in the open position and in the second stop region of the two guide profiles in the closed position. For this purpose, the guide arm can have, for example, a latching lug which can engage in a latching region which can then be embodied in the form of a recess. However, it is also possible for the first and second stop regions to each have a stop lug and for the guide arms to each have a recess, wherein the stop lug of the first or second stop region can then engage in the recess on the respective guide arm, depending on the position of the cover element.

In order to form the pivoting movement, the cover element can have a pivot axis via which the cover element can be mounted on the base frame in a pivotable movement. The rotation axis is preferably formed on the lower end of the covering element. The guide arm is then preferably molded on the upper end of the cover element remote from the lower end formation. A rotary shaft receptacle may be formed on the base frame, in which the rotary shaft may be rotatably supported. The rotary shaft receiving portion may be formed as two recesses provided to face each other on the inner surface of the base frame.

In order to form the rotary shaft, the cover element can have a pin body on each of the first and second transverse sides, which pin bodies can each be mounted in a rotationally movable manner in a recess formed in the base frame, which recess forms the rotary shaft receptacle.

The object is also achieved according to the invention by a plug connector having a housing, a holding frame arranged in the housing, and a plurality of contact inserts accommodated in the holding frame, wherein the holding frame is constructed and improved as described above.

Detailed Description

Fig. 1 to 5 show a schematic illustration of a holding frame 100, which can be arranged in a housing of a plug connector.

Each holding frame 100 has a base frame 110, which is formed in one piece. The base frame 110 may be formed of a metal material or a plastic material.

The base frame 110 includes a first sidewall 111, a second sidewall 112 opposite to the first sidewall 111, a first end wall 113, and a second end wall 114 opposite to the first end wall 113. The two

side walls

111, 112 are arranged parallel to each other. The two

end walls

113, 114 are likewise arranged parallel to one another. The

end walls

113, 114 are arranged at a 90 ° angle to the

side walls

111, 112. Together, the two

side walls

111, 112 and the two

end walls

113, 114 enclose or otherwise define an interior space 115 of the base frame 110. In this interior 115, the contact insert 200 can be inserted and fixed in the insertion direction E, as is shown, for example, in fig. 1.

As can be seen in particular in fig. 7, the first side wall 111 of the base frame 110 has a significantly smaller height than the second side wall 112 of the base frame 110. Compared to the second side wall 112, a recess 116 is formed in the first side wall 111, which also results in a smaller height of the first side wall 111.

A positioning element 117 extends in this recess 116, and this positioning element 117 is detachably fastened to the base frame 110 or to the first side wall 111 of the base frame 110. Such a pre-positioning element 117 can also be seen in fig. 6.

The predetermined position element 117 is formed by a spring leaf, so that the predetermined position element 117 can be elastically deformed when the contact insert 200 is introduced into the interior 115 of the base frame 110 and is removed from the interior 115 of the base frame 110.

The pre-positioning element 117 has a fastening section 118, by means of which the pre-positioning element 117 can be fastened to the base frame 110.

Furthermore, the pre-positioning element 117 has a plurality of spring webs 119, on which the contact insert 200 introduced into the interior 115 of the base frame 110 can be held. Between the individual spring webs 119, a gap 120 is formed here, as can be seen in fig. 6, so that the spring webs 119 can be elastically deformed separately from one another. Each contact insert 200 that can be inserted into the holding frame 100 can correspond to a spring web 119.

In the region of the spring webs 119, the prepositioning element 117 has a holding region 121, to which the contact insert 200 can be fixed with its projecting elements 210. The holding regions 121 are each formed here in the form of a window-like opening through which the projecting element 210 can pass.

The fastening portion 118 is bent into a U shape, so that the predetermined position element 117 can surround the lower edge 122 of the base frame 110 or the first side wall 111 of the base frame 110 in order to fasten the predetermined position element 117 to the base frame 110 or the first side wall 111 of the base frame. Furthermore, a plurality of stop elements 123 are formed in the region of the fastening section 118, which can engage in openings 124 formed on the first side wall 111. The latching element 123 is formed here in the form of a latching tab.

In addition to the prepositioning element 117, a cover element 125 is arranged on the first side wall 111 of the base frame 110, which cover element covers the prepositioning element 117 from the outside in its closed position, as shown for example in fig. 1, in such a way that the cover element 125 covers an outer surface 146 of the prepositioning element 117 facing away from the interior 115 in the closed position.

In contrast to the pre-positioning element 117, the cover element 125 is not of elastic design, but rather is of rigid or flexurally rigid design. In the closed position, the cover element 125 extends parallel to the prepositioning element 117, wherein the cover element 125 is arranged tightly on the prepositioning element 117 such that an outward bending or springing of the prepositioning element 117 can be prevented by the cover element 125, whereby the cover element 125 can provide the prepositioning element 117 with shape stability. In the open position of the cover element 125, the latter is tilted away from the pre-positioning element 117, as can be seen in fig. 3, so that there is no longer contact between the cover element 125 and the pre-positioning element 117, and therefore the cover element 125 in this open position can no longer prevent the pre-positioning element 117 from being elastically deformed.

The cover element 125 forms a side cover arranged on the first side wall 111, which can be tilted relative to the base frame 110 and also relative to the prepositioning element 117 arranged on the base frame 110. The cover element 125 has holding regions 126, which can correspond to the holding regions 121 formed on the pre-positioning element 117. Each holding region 126 of the cover element 125 is formed in alignment with one holding region 121 of the prepositioning element 117, so that the projecting elements 210 of the contact insert 200, which project through the holding regions 121 of the prepositioning element 117, can also project through the holding regions 126 of the cover element 125. The fixing of the contact insert 200 by way of its projecting elements 117 is thus effected not only by way of the prepositioning elements 117 but also by way of the cover element 125 in the closed position of the cover element 125. The holding region 126 of the cover element 125 is designed in the form of a window-like opening, like the holding region 121 of the predetermined bit element 117.

By the cover element 125 forming an upwardly configured extension of the first side wall 111, the cover element 125 extends together into the recess 116 of the first side wall 111 in the closed position. The height of the first side wall 111 together with the cover element 125 substantially corresponds to the height of the opposite second side wall 112.

In order to guide the cover element 125 into the closed position and into the open position, a first guide contour 127 and a second guide contour 128 opposite the first guide contour 127 are formed on the base frame 110. The two

guide profiles

127, 128 each have an arc shape. The two

guide contours

127, 128 are each formed on the base frame 110 in the form of a trough-shaped recess, wherein the two

guide contours

127, 128 are formed on the

inner surfaces

129, 130 of the two

end walls

113, 114 of the base frame 110 which face the interior 115.

For guiding the covering element 125 in the two

guide profiles

127, 128, the covering element 125 has a first guide arm 131, which is guided in the first guide profile 127, and a second guide arm 132, which is guided in the second guide profile 128. The two guide

arms

131, 132 are formed symmetrically to each other. A first guide arm 131 is molded on a first lateral side 133 of the covering element 125 and a second guide arm 132 is molded on a second lateral side 134 of the covering element 125, wherein the two guide

arms

131, 132 extend at right angles away from the main plane of extension or away from a longitudinal side 135 of the covering element 125, as can be seen in fig. 8.

In order to be able to hold the cover element 125 in a fixed and secure position both in the closed position and in the open position, the two

guide contours

127, 128 each have a first stop region 136 and a second stop region 137, wherein in the open position the

guide arms

131, 132 of the cover element 125 engage in a stop manner in the first stop regions 136 of the two

guide contours

127, 128, as can be seen in particular in fig. 3 and 4, and in the closed position, as can be seen in particular in fig. 1 and 2, engage in a stop manner in the second stop regions 137 of the two

guide contours

127, 128. The

guide arms

131, 132 each have a stop lug 138, which can engage in a

stop region

136, 137, which is embodied here in the form of a recess.

In order to form an oscillating movement of the cover element 125, it has a rotational axis 139 as can be seen in fig. 8. The rotational axis 139 is formed in the form of two

pins

140, 141, a first pin 140 being formed on the first transverse side 133 of the cover element 125 and a second pin 140 being formed on the second transverse side 134 of the cover element 125.

Recesses

142, 143, in each case, are formed in the base frame 110, in particular in the inner faces 129, 130 of the two

end walls

113, 114 of the base frame 110, in which recesses one of the two

pins

140, 141 is rotatably mounted in each case. Two

pins

140, 141 are molded on the lower end 144 of the covering element 125, while two guide

arms

131, 132 are molded on the upper end 145 of the covering element 125.

If the contact insert 200 is to be inserted into the holding frame 100, the cover element 125 is first pivoted into the open position. The contact insert 200 can then be inserted into the interior 115 along the insertion direction E, wherein one of the two projecting elements 210 of the contact insert 200 can snap into the window-shaped opening 147 on the second side wall 112 of the base frame 110 and the other of the two projecting elements 210 of the contact insert 200 can snap into the holding region 121 of the prepositioning element 117 opposite the window-shaped opening 147 of the second side wall 112. The contact insert 200 can be easily inserted one-handed by the spring action of the predetermined position element 117. After insertion of the contact insert 200, the cover element 125 can be pivoted from the open position into the closed position, wherein the projecting element 210, which passes through the holding region 121 of the predetermined position element 117, can also pass through the holding region 126 of the cover element 125, so that the contact insert 200 can be held and fixed in the fixed and inserted position both on the predetermined position element 117 and on the cover element 125 in the region of the first side wall 111.

The prepositioning element 117 and the cover element 125 are provided here only on one of the two

side walls

111, 112 of the base frame 110, whereas the other of the two

side walls

111, 112, here the second side wall 112, is formed rigidly or flexurally and has no spring-elastic properties at all.
