Technical Field

The invention relates to a connecting assembly comprising: a first housing part including a contact member accommodating part for the contact member and a latch member for latching the contact member in the contact member accommodating part; a second housing portion configured to be plugged with the first housing portion; a joint connector held between the first housing portion and the second housing portion and configured to connect at least two contact members.

Disclosure of Invention

The object of the invention is to make such a connection assembly safer.

According to the invention, it is sufficient if the second housing part comprises at least one locking portion which locks one of the latch elements in the latching position.

Due to the locking, the contact elements cannot loosen and the connection assembly is more secure.

The invention can be further improved by the following developments and embodiments, which are each advantageous per se and can be combined with one another in any desired manner.

The locking portion may be configured as a protrusion for enabling simple assembly. The locking portion may be configured, for example, as an arm or a strap in order to save space in particular. The arm or strap may be fixed at one end and movable at the other end.

The projections may be tapered in a direction away from the base plate to facilitate insertion into the corresponding mating element. For example, the protrusion may be wedge-shaped.

The locking portion may extend into the first housing portion when the housing portions are plugged together. It can extend particularly adjacent to the contact element receptacle when the housing part plugs together, in order to enable simple locking.

When the housing parts are plugged together, in an advantageous embodiment, the locking portion may extend beyond a first half of the contact element accommodating part facing the second housing part, when viewed from the second housing part. This makes it possible to achieve a firm connection.

The locking portion can prevent the locking element from moving out of the latching position, for example in a mechanical and/or form-fitting manner. Locking can be achieved in a simple manner.

For a secure locking, the locking portion may be arranged between the latch element and a wall portion of the first housing part when the housing parts are plugged together. Whereby a flow of force can be established. The locking portion is capable of abutting against the latch element and the wall portion and mechanically blocking movement of the latch element towards the wall element. The locking portion may be supported by the wall portion.

The first housing part may comprise a receptacle for a part, in particular an end, of the locking part and may achieve a defined fixing.

The receptacle can be arranged behind and/or defined by the latching element in order to achieve a space-saving configuration. The wall portion may also define a receptacle.

When a part of the locking portion is received in the receiving portion, the locking member may be locked.

The first housing part may comprise slots for the locking portions in order to achieve a space-saving configuration. The slot may be at least partially complementary to the locking portion.

The slot may extend parallel to the contact element receptacle to enable a simple interaction. The slot and the contact element receptacle can each be designed as an elongate cavity, for which purpose the extension in one direction is significantly greater by a factor of two or more than in the other direction.

In an advantageous embodiment, the locking element can project into the contact element receptacle. This allows for a simple latch. In particular, the latching element in the force-free state can project into the contact element receptacle. They may be deflectable such that they do not project or project less into the contact element receptacles in the deflected state. This may enable automatic latching. The latching element may be deflected by the contact element during insertion and may latch with the contact element when the contact element is fully inserted.

In another advantageous embodiment, the locking portion is integrally connected to the rest of the second housing part. This allows for simple manufacture.

Furthermore, the latch element may be integrally connected to the rest of the first housing part. This also makes the manufacture simple.

The joint connector serves for electrically contacting the contact elements, for example, so that they assume the same electrical potential. In order to enable contact to be established also from the outside, the joint connector may comprise a connecting portion which, at least in the assembled state, protrudes from the first housing part and/or the second housing part. This may enable connection to the ground or earth, for example.

The connection assembly may comprise a sealing element, which may be inserted into the first housing part. The sealing element may be used to seal the contact element against external influences, in particular liquids and dust.

The sealing element may be made of a flexible, in particular compressible material, or comprise such a material for obtaining a good seal.

The sealing element may comprise a closed circumferential projection or recess which interacts with a closed circumferential recess or projection on the housing part and may thereby be held in a sealing manner on the housing part.

The locking portion may extend through the sealing element. The sealing element may have a passage hole for the locking portion for this purpose. The locking portion and the sealing element may be connected to each other in a sealing manner at the passage hole.

In a further advantageous embodiment, the joint connector, in particular the connecting portion, can extend through the sealing element. To this end, the sealing element may comprise a passage hole for the joint connector. The joint connector and the sealing element can be connected to each other in a sealing manner at the passage hole.

Furthermore, the joint connector, in particular the connecting portion, may extend through the second housing part, so that simple contacting may be achieved. To this end, the second housing part may comprise a passage hole for the joint connector.

In order to obtain a good sealing effect, the sealing element may be at least partially moulded or injected to the joint connector. The sealing element may be a sealing element connected to the joint connector by injection molding. The joint connector may be embedded in the sealing member.

In order to increase the sealing effect, the second housing part can exert a pressure on the sealing element in the assembled state. This can be achieved, for example, because the sealing element receptacle is smaller than the sealing element. The sealing member accommodating portion may be formed by the first housing portion. The seal member housing portion may be configured such that a portion of the seal member facing the second housing portion in an uncompressed state protrudes and is compressed by the second housing portion.

In an advantageous embodiment, the connection assembly comprises an attachment mechanism by which the second housing part can be attached to the first housing part. The attachment mechanism may in particular be a latching mechanism which latches the first housing part to the second housing part in the latched position. The second housing portion may lock the latch element when the latch mechanism is in the latched position. This can realize a simple operation.

The processing can be easier if at least two of the following directions extend in parallel or anti-parallel:

-an insertion direction along which the contact element is inserted into the contact element receptacle;

-a plugging direction along which the second housing part is plugged together with the first housing part;

a locking direction along which the locking portion is displaceable relative to the contact element receptacle;

-a compression direction along which the second housing part exerts a pressure on the sealing element.

By this construction, in particular, transverse forces which may lead to damage or make handling more difficult can be prevented or reduced.

In order to achieve a simple and secure locking, the locking direction in which the locking portion can be displaced relative to the contact element receptacle can extend perpendicular to the deflection direction of the latch element.

For simple locking of the plurality of contact elements, the second housing part may comprise locking portions for the plurality of contact elements. In particular, the second housing part may comprise a locking portion for all contact elements. There may be as many locking portions as there are contact elements, such that each locking portion is associated with a contact element. To reduce complexity, the locking portion may lock a plurality of latch elements for each contact element. Furthermore, a single latching element may latch a plurality of contact elements.

In an advantageous configuration, the plurality of locking portions may have a common base. This may increase stability. The common base may protrude from the base plate. As a result, the rest of the locking portion can be constructed shorter and stability can be increased. The sealing element may seal in the region of the common base portion such that the sealing surface is smaller than in the case of sealing a plurality of locking portions separately. To this end, the sealing element may comprise a single passage hole for the common base.

The latching element may be arranged between the contact element and the second housing part in order to achieve a good locking.

In a further advantageous configuration, the contact element can be arranged between the latching element and the second housing part. This enables the connection assembly to be stable.

The second housing part may be arranged on the opposite side of the first housing part to the side in which the contact element is inserted. This allows for simple assembly.

Detailed Description

The connection assembly 100 is shown in different views and with different components in the figures. The connecting assembly 100 serves to establish the same potential on different lines, which for this purpose are connected to the joint connector 40 by means of the contact elements 12, otherwise known as a comb connector. The joint connector 40 comprises, in particular, a single metal part, which further comprises a connection portion 41, by means of which connection portion 41, for example, external contact can be made in order to establish a connection to ground.

The connection assembly 100 comprises a first housing part 10 comprising a contact element receptacle 11 for a contact element 12 and a latching element 14 for latching the contact element 12 in the contact element receptacle 11. The latching elements 14 are each configured as a projection 60 in the form of an arm 15, the arms 15 being integrally connected at a fixed end to the remainder of the first housing part 10 and being elastically deflectable at a free end. In particular, the latching element 14 in the force-free state projects into the contact element receptacle 11. When the contact element 12 is inserted in the insertion direction E, the free end of the latching element 14 is deflected in a deflection direction a which extends perpendicularly to the insertion direction E. When the end position of the contact element 12 is brought into the contact element receptacle 11, the latching element 14 latches automatically, so that the contact element 12 is fixed in the contact element receptacle 11.

The connecting assembly 100 further comprises a second housing part 20 which can be plugged together with the first housing part 10 in a plugging direction Z and then form a housing 110. In the plugged state, the joint connector 40 is held between the first housing part 10 and the second housing part 20. If the contact elements 12 are plugged, the joint connector 40 connects these contact elements 12 to one another in an electrically conductive manner.

In the example shown, the second housing part 20 comprises a plurality of locking portions 21, wherein a respective locking portion 21 locks the latch element 14 in the latching position 91. The latching position 91 is the position in which the latching element 14 secures the contact element 12 in the contact element receptacle 11. In the example shown, the respective latching elements 14 are associated with the contact element 12 and the contact element receptacle 11. In other embodiments, multiple contact elements 12 may be secured by the latch element 13 and/or the locking portion 21 may be used for multiple contact elements 12 and/or latch elements 14.

The locking portions 21 are respectively configured as protrusions 22 that protrude with respect to a base plate 23 of the second case member 20. In the example shown, a plurality of locking portions 21 are arranged on a common base 25, which common base 25 in turn protrudes from the base plate 23.

The locking portion 21 is configured as an arm 28 which narrows, i.e. tapers and is wedge-shaped, in a direction away from the base plate 23.

When the housing parts 10, 20 are plugged together, the locking portion 21 extends from the second housing part 20 into the first housing part 10. Each locking portion 21 is arranged at least partially adjacent to the contact element receptacle 11. Each locking portion 21 extends beyond the first half 16 of the contact element accommodating portion 11 facing the second housing portion 20 when viewed from the second housing portion 20.

The first housing part 10 comprises a plurality of receptacles 18 for each respective part, in particular the free end of the locking part 21. In the plugged state, parts of the locking portion 21 are arranged in the receptacle 18 and prevent the associated latching element 14 from deflecting in a form-fitting manner. The locking portion 21 is arranged between the latch element 14 and the wall portion 19 of the first housing part 10. In the plugged state, the locking portions 21 are located in the slots 17 in the first housing part 10, respectively. The slot 17 extends parallel to the contact element receptacle 11.

The receptacles 18 are respectively arranged behind the associated latching element 14, i.e. are defined by the latching element 14 and the wall portion 19. The latch element 14 is functionally arranged between the contact element 12 and the locking portion 21 of the second housing part 20. At the same time, the contact element 12 is arranged between the latch element 14 and the base plate 23 of the second housing part 20.

The locking portions 21 are integrally connected to the remaining portions of the second housing portion 20, respectively.

The connection assembly 100 further comprises a sealing element 30 insertable into the first housing part 10. The locking portion 21 extends through the sealing element 30. To this end, the sealing element 30 comprises a passage hole 32, which receives the common base 25, in particular in a sealing manner.

The nipple connector 40 likewise extends through the sealing element 30. The joint connector 40 also extends through the second housing part 20, which for this purpose comprises a passage hole 24. The joint connector 40 is connected to the sealing member 30 by injection molding. During the manufacturing process, the sealing element 30 is injected onto the joint connector 40, whereby the passage hole 34 is automatically created. The joint connector 40 is then at least partially embedded in the sealing element 30.

The first housing part 10 and/or the second housing part 20 in the assembled state may exert a pressure on the sealing element 30 to compress it, so that a good sealing effect is obtained. The sealing member receiving portion 13 in the first housing portion 10 may be smaller than the sealing member 30 so as to automatically compress it. The second housing part 20 may also create pressure and compress the sealing element 30 when the plugs are together.

The two closed circumferential projections 31 on the sealing element 30 interact with the closed circumferential recesses 33 on the first housing part 10, so that the sealing element 30 is held in a form-fitting manner.

The connection assembly 100 further comprises an attachment mechanism 50 in the form of a latching mechanism 21 by which attachment mechanism 50 the second housing part 20 can be attached to the first housing part 10. In the latched position 52, in which the first housing part 10 is latched to the second housing part 20, the second housing part 20 automatically latches the latch element 14 by means of the latch element 21.

The insertion direction E in which the contact element 12 is plugged into the contact element receptacle 11 is anti-parallel to the locking direction V in which the locking portion 21 can be displaced relative to the contact element receptacle 11. The plugging direction Z along which the second housing part 20 is plugged together with the first housing part 10 is also anti-parallel to the insertion direction B and parallel to the compression direction K along which the second housing part 20 exerts a pressure on the sealing element 30.

The second housing part 20 is arranged on the side of the first housing part 10 opposite to the side where the contact element 12 is inserted.

The manufacture of the components of the connection assembly 100 is illustrated in fig. 10 to 18. After the respective piece has been punched out of the sheet metal, it is bent to be able to be contacted in different planes. In a subsequent step, the sealing element 30 is molded or sprayed onto the already formed joint connector 40.
