Description

Electrical connection terminal

The invention relates to an electrical terminal for performing ei¬ ner line through a housing wall, with a rechteckfδrmigen terminal housing made of insulating material, with at least one connecting element and ei¬ nem fastener for fixing the terminal in a rectangular eck¬ wall opening of the housing wall, said Fastening element has at least one fixing element. In addition, the invention also relates to a fastening element for fixing an electrical terminal in a wall opening of a housing wall, with at least one fixing element.

Electrical connection terminals or electrical plug connectors for carrying out a line through a housing wall are frequently also referred to as lead-through terminals or as feed-through connectors. Both one-piece and two-piece lead-through terminals are known. In the case of two-part lead-through terminals, one part of the terminal is fastened in the wall opening of the housing wall, while the other part is connected electrically and mechanically to the part which is fastened in the wall opening - the plug part.

Electrical connectors are used in electrical terminals together with corresponding connection plugs for connecting an elec¬ cal conductor to the electronics of a device. Depending on the embodiment, the electrical connector can be designed as a socket part or as a plug part. Since the electrical connector is electrically and mechanically connected to the electronics or to the housing of the device, while an electrical line is connected to the corresponding connector, the stationary electrical connector is often referred to as the base body or base housing. Various embodiments of electrical plug connectors or corresponding connection plugs, ie different base bodies and different plug components, are known, for example, from the Phoenix Contact catalog "COMBICON 2002", pages 196 to 203. In this case, the different connector parts differ in particular by the different connection options for the conductors to be connected. Plug-in parts with screw, spring-loaded, crimp and insulation displacement contacts are known. In contrast, the connectors or the base body differ in particular by whether the contact element has a pin contact or a socket contact as a contact leg, wo¬ in the embodiment with a pin contact is the standard version. If the electrical plug connector has a pin contact as the contact leg, then the plug connector is designed as a socket part, into which the plug connector, which has a socket contact, is plugged.

For fixing in the wall opening in the housing, it is irrelevant whether it is an electrical terminal or an electrical Anschluß¬ plug. For this reason, in the context of this invention, the following is always spoken of an electrical terminal, which is to be understood as including an electrical connector.

There are various ways known to attach electrical terminals in the wall opening of a housing wall. From DE 36 13 681 Cl, for example, a two-part terminal is known, wherein both parts of the electrical terminal mutually corresponding Rast¬ elements which mate when nesting the two Anschlußklem¬ menteile each other and prevent separation of the two Anschlußklem¬ menteile against the joining direction. Both parts of the connection terminal are inserted in the opposite direction through the wall opening in the housing wall, so that the housing wall is clamped between the parts of the connection terminal.

A similar principle follows the teaching of DE 198 01 260 C2, in which the one-piece terminal housing is guided through the wall opening. The insertion process is limited by a stop on the terminal housing be¬. On the run through the wall opening part of the electrical An¬ terminal clip then a locking bracket is pushed, which locks with two opposite sides of the housing of the terminal, so that the housing wall between the stop on one side and the locking bracket is fixed on the other side. A disadvantage of the described mounting options u. U. considerable installation problems that only result from the fact that the housing wall must be accessible on both sides, ie from the inside of the housing as well as the Gehäuse¬ outside. Furthermore, there is the danger, particularly in the case of installation sites which are difficult to access, that a component of the multi-part terminal built up is lost.

From DE 202 00 974 Ul a one-piece terminal is known, which is inserted through the wall opening of the housing, wherein when inserting the terminal through the wall opening on two gegenüber¬ opposite sides of the housing provided spring detents are each pushed back by an inner edge of the wall opening , The spring detents spring back after passing through the wall and thus lock with the corre sponding inner edge of the wall opening. For final fixation of the terminal in the wall opening a renewed spring back springing must be prevented by a blocking slide, which can only be operated from the inside of the housing, while the terminal must first be inserted from the outside into the wall opening, so that here as well Access to both sides of the housing wall is necessary.

DE 103 15 661 A1, from which the invention proceeds, discloses an electrical terminal which is inserted as a unit in the wall opening of the housing wall up to a stop, whereupon locking elements can be pressed by an actuating element against two opposite inner edges of the wall opening, so that the electrical connection terminal - in the direction of action of the locking elements - is firmly fixed in the wall opening.

However, it can be disadvantageous here as well that latching takes place only with two opposite inner edges of the wall opening. This has the consequence that in the presence of a tolerance between the electrical Anschluß¬ terminal and the wall opening movement of the terminal in the wall opening can not be reliably prevented. - A -

The teaching of the present invention is therefore based on the object of providing an electrical terminal with improved properties in the fastening in a wall opening of a housing wall.

The electrical terminal according to the invention, in which this object is achieved, is initially and essentially characterized in that the fastening element additionally comprises a resilient clamping element which is arranged substantially perpendicular to the fixing that the clamping element in the assembled state of the terminal against an In - Edge of the narrow side of the wall opening acts.

The erfϊndungsgemäße electrical terminal is advantageous in many ways. Due to the resilient clamping element, it is possible to close tolerances between the inner edge of the narrow side of the wall opening and the clamping housing, wherein the compensable play between the An¬ terminal and the inner edge of the wall opening is determined by the maximum travel of the resilient clamping member. In addition to this purely geometric clearance compensation causes the resilient clamping element at the same time a fixation of the terminal in the wall opening of the housing wall in the direction of this inner edge of the wall opening. At the same time the resilient clamping element fixes the terminal in the wall opening in the joining direction or in the direction opposite to the joining direction, d. H. perpendicular to the actual main clamping direction.

The terminal according to the invention can be further improved in terms of their fixation in the opening of the housing wall by the resilient clamping element has a curved or oblique clamping surface and the Klemmflä¬ che in turn a plurality of mutually parallel ribs. In the mounted state of the terminal then forms at least one rib depending on the strength of the housing wall with the inner edge of the wall opening a toothing. As a result, the connection terminals can be fixed in wall openings of housings with different wall thicknesses. The extent of the curved or oblique clamping surface in the joining direction of the terminal defines the maximum thickness of the housing wall, with which the resilient clamping element can cooperate, so that the ge desired locking effect is achieved with the inner edge of the wall opening. Particularly advantageously, the terminal according to the invention can be formed with respect to its latching in the opening of the housing wall, in which the fastening element has an actuating wedge, which is arranged pivotably on the fastening element such that it can be pivoted into a position in which the resilient clamping element is pressed in the assembled state Zu¬ the terminal by the actuating wedge against the corresponding inner edge of the wall opening. So that the position of the spring-loaded clamping element can also be held permanently in the installed state of the terminal, the actuating wedge can be fixed in this position.

When pivoting the actuating wedge in its mounting position of the actuating wedge penetrates between the resilient clamping element and the Klemmgehäu¬ se, so that is moved by the wedge action exerted by the wedge wedge ver¬ the clamping element from the terminal housing on the opposite inner edge of the housing wall. The resilient Klemm¬ element is thus pressed against the auf¬ by the deflection of the clamping element auf¬ passing spring force of the actuating wedge outward against the Innen¬ edge of the wall opening. In the described advantageous development of the terminal according to the invention, the clamping element thus lies comparatively tight against the terminal housing and is only deflected by the force effect of the actuating wedge.

In order for this deflection remains permanently in the assembled state, the actuating wedge must remain in the position described. This is advantageously achieved by forming a toothing on the surface of the actuating wedge and a corresponding counter-toothing on the side of the fixing element facing the surface of the actuating wedge. Such an embodiment of the actuating wedge thereby ensures a reliable fixing of the terminal in the opening of the housing wall, that the resilient clamping element is pressed against the inner edge of the wall opening and simultaneously held in its mounting position.

The above-mentioned object is further achieved with a fastening element for fixing an electrical terminal in a wall opening of a housing wall, with at least one fixing element passing through it characterized in that a resilient clamping element is provided, which is arranged substantially perpendicular to the fixing element, wherein the fastening element, a substantially U-shaped base body, with a U-back and two U-legs and a substantially parallel to the ground - Body extending latching tongue has Here, the ends of the two U-legs are each formed as a fixing and the resilient Klemmele¬ element is formed by the free end of the latching tongue. The spring force of the clamping element is directed substantially perpendicular to the longitudinal direction of the fixing.

The fastening element according to the invention can be configured particularly advantageously if the latching tongue is in turn attached with its foot region in the region of the U-back of the fastening element. The advantage of the fastening element according to the invention lies in its simple geometry, which is particularly unproblematic in the production as well as in the further application, for example when attaching such a fastening element to an electrical connection terminal.

A further improvement of the fastening element can be achieved in that the free end of the latching tongue has an outwardly directed curved or oblique clamping surface and on the clamping surface a plurality of paral¬ lel to each other extending ribs are formed. As a result of this improved design, the fastening element can cooperate securely with an inner edge of the opening in the housing wall and securely fix the electrical terminal in the wall opening.

According to a further embodiment of the fastening element, an actuating wedge is arranged pivotably at the free end of a U-leg. The actuating wedge is pivotable into a position such that it presses the resilient clamping element in the assembled state of the terminal against the ent speaking inner edge and thus ensures a secure fixation of the An¬ terminal in the wall opening. By means of the actuating wedge, the resilient clamping element can thus be deflected against its spring force, whereby the connecting terminal is fixed in the wall opening in the mounted state. In particular, there are various possibilities for designing and further developing the connection terminal according to the invention and the fastening element according to the invention. Reference is made to the patent claims 1 and 9 subordinate claims and to the description of preferred embodiments in conjunction with the drawings. In the drawing show

Fig. 2 is another perspective view of the electrical terminal according to the invention shown in FIG. 1 and

Fig. 3 shows a preferred embodiment of an inventive

Fastener.

FIG. 1 shows an electrical terminal 1 for conducting a line through a housing wall 2. The terminal 1 has a rectangular terminal housing 3 made of insulating material with three connecting elements in this specific embodiment, the connecting elements being connected and connected two ends of a respective fastening element 4 for fixing the terminal 1 in a likewise rectangular wall opening 5 are limited. The number of connection elements of the Anschluß¬ terminal 1 is completely irrelevant to the teaching underlying the electrical terminal An¬ terminal according to the invention; just as well, a preferred embodiment could have been shown with fewer but also more connecting elements. In particular, a plurality of disk-shaped connection terminals 1, each with one connection element, can be joined together to form a terminal block, in which case the terminal block has a fastening element 4 on two sides.

The fastening element 4, which is shown in isolation in FIG. 3, has two fixing elements 6, 7 which, in the installed state of the terminal 1, rest respectively against an inner edge 8, 9 of the wall opening 5 or slightly Press against the inner edges 8, 9 and so cause a prefixing of the electrical terminal 1 in the wall opening 5. The two fixing elements 6, 7 are arranged opposite one another, so that they also interact with two mutually opposite inner edges 8, 9 of the wall opening 5. In the embodiment, these are the longitudinal sides of the wall opening 5. In the prior art, in particular in the known from DE 103 15 661 Al terminal, the fixation of Anschluß¬ terminal 1 in the wall opening 5 is exclusively on locking elements, on the long sides of the wall opening 5 attack.

In contrast, the Anschluß¬ shown in FIGS. 1 and 2 terminal 1 on a resilient clamping element 10 which presses in the assembled state of the terminal 1 against a further inner edge 11 - a narrow side - the wall opening 5. The inner edge 11 extends perpendicular to the two inner edge 8, 9. Because the fastening element 4 of An¬ terminal 1 not only acts in a known manner against the two inner edges 8, 9 of the wall opening 5, but in particular with the resilient clamping element 10 against presses the inner edge 11 of the narrow side, a fixation of the terminal 1 is ensured in the direction of this inner edge 11, d. H. in a horizontal direction. The resilient clamping element 10 of the fastening element 4 thus also makes it possible to securely mount an electrical terminal 1 in such a wall opening 5, which normally would surround the electrical terminal 1 only with a certain play and formed gaps.

In the preferred exemplary embodiment in FIGS. 1 and 2, the resilient clamping element 10 of the electrical terminal 1 has an oblique, slightly curved clamping surface 12, with a plurality of mutually parallel ribs 13 in the clamping surface 12. The ribs 13 are arranged so that at least one rib 13 forms a toothing in the assembled state of the connecting terminal 1 with the inner edge 11 of the wall opening 5. Which of the mutually parallel ribs 13 cooperates with the inner edge 11, depends on the strength of the Ge housing wall 2 from as well as the distance by which the resilient clamping element 10 must be deflected until it with the inner edge 11 of Wandöff 5 cooperates. From Figs. 1 and 2 and from the above It can be seen that the electrical terminal 1 can be fixed in the wall opening 5 of housing walls 2, which have different wall thicknesses. The extent to which the wall thickness of the housing wall 2 can vary depends structurally on the extension of the clamping surface 12 in the joining direction of the electrical terminal 1.

In the illustrated exemplary embodiment of the electrical terminal, the fastening element 4 has an actuating wedge 14, which is arranged pivotably on the fastening element 4. The actuating wedge 14 is pivoted in Figs. 1 and 2 - each in the front position - so in a Montagepo¬ position that he the fixing elements 6, 7 and in particular the fe¬ decent clamping element 10 against the corresponding inner edge 8, 9 and 11 the wall opening 5 presses. So that the so effected fixation of the terminal 1 in the wall opening 5 is permanently maintained, the actuating wedge 14 is fixed in its mounting position.

The fixation of the actuating wedge 14 is realized in the exemplary embodiment by the fact that a toothing 15 is formed on the surface of the actuating wedge 14. This toothing 15 cooperates with a corresponding counter toothing 16, which is formed on the side of the first fixing element 6 facing the surface of the actuation wedge 14. The embodiment of the actuating wedge 14 shown in the figures has a double effect when the actuating wedge 14 is pivoted into its mounting position. The first, known effect is that the fixing elements 6, 7 are pressed against the inner edges 8, 9 of the wall opening 5, at least slightly, and the actuating wedge 14, due to its serration 15, is pressed by the corresponding counter-toothing 16 of the first Fi¬ xierelements 6 locked. The second effect is that the Actuate wedge 14 slides during pivoting in its mounting position between the resilient clamping element 10 and the terminal housing 3, whereby the resilient clamping element 10 due to the wedge-shaped shape of Actuate wedge 14 away from the terminal housing 3 in the direction is deflected to the inner edge 11 of the narrow side of the wall opening 5, so that at least one of the ribs 13 of the clamping surface 12 interacts with the inner edge 11. The farther the actuating wedge 14 is pivoted, the farther the clamping element 10 is deflected or pressed against the inner edge 11.

1 and 2, a stop 17 is shown in each case, which is formed on the terminal housing 3. The illustrated electrical Anschlußklem¬ me 1 is so far passed through the wall opening 5 until the stop 17 touches the housing wall 2, so abuts her. The fixing element 6, 7 and the further clamping element 10 are formed so that they not only prevent a movement of the terminal 1 in the plane of the housing wall 2 in the assembled state of the terminal 1 but also a movement of the terminal 1 in the joining direction opposite direction.

The electrical connection terminal 1 with the stop 17 formed on it is only one possible variant for effecting the desired clamping effect in connection with the further resilient clamping element 10 of the fastening element 4; However, the stop 17 is by no means functionally necessary for the teaching of the invention. In another, not darge here darge embodiment of a terminal according to the invention, the clamping surface of the fixing element 6, 7 and the clamping surface of the resilient clamping member 10 in the direction of the first inner edge 8, 9 and the further inner edge 11 formed as a limited on both sides recess , Differently strong housing walls 2 penetrate at different depths into the described recess in the assembled state, whereby the clamping surfaces formed in this way are able to prevent a movement of the electrical terminal both in the joining direction and in the opposite direction of the joining direction. In another exemplary embodiment, which is likewise not shown here, the stop and the fastening element are accessible from one side of the housing wall in the assembled state of the electrical terminal. For the above embodiment, reference is made to DE 103 15 661 A1, in particular to the FIG. 2 shown in this publication.

In the exemplary embodiment in FIGS. 1 and 2, the fastening element 4 is designed separately from the terminal 1 and can be fastened laterally to the terminal housing 3 by means of a latching or in each case a pocket 18 formed on both sides of the terminal housing 3 and can be inserted there a locking lug 19 latched. The advantage of a separate version the fastening element 4 of the electrical terminal 1 is that both parts are separated from each other easier to produce than in a unit. On the other hand, it is then possible to replace a destroyed Befestigungs¬ element 4 by an intact fastener 4, without having to replace immediately the entire electrical terminal 1. Finally, there is the further advantage that the fastening element 4 can be fastened laterally to a terminal block which is formed from any desired number of slotted disk-shaped connecting terminals 1.

In a further, not shown here embodiment of an electrical terminal 1, the terminal housing 3 with the fastening element 4 is integrally formed.

In the exemplary embodiment illustrated in FIGS. 1 and 2, a symmetrical clamping effect is achieved by arranging, in each case, a fastening element 4 on two sides of the terminal housing 3 which are opposite one another, or being inserted in the two pockets 18. This prevents that in a tensile load of the electrical terminal 1 in or against the joining a one-sided slipping out or breaking the terminal 1 from the wall opening 5 is already structurally pre-programmed.

Fig. 3 shows a preferred embodiment of a fastener 4 according to the invention, as well as in Figs. 1 and 2 in connection with the terminal 1 is used. It has two fixing elements 6, 7, which in the assembled state of the terminal 1 against a respective first inner edge 8, 9 of the wall opening 5 and den. The fastening element 4 is used to fix an electrical terminal 1 in a Wandöff¬ opening 5 of a housing wall Stop 17 act on the terminal housing 3. The fastening element 4 further comprises a resilient clamping element 10 which is arranged substantially perpendicular to the two fixing elements 6, 7 in such a way that the spring force of the clamping element 10 is directed substantially perpendicular to the holding force of the fixing elements 6, 7. By means of this simple construction, it is possible for the holding and clamping forces, which can be exerted by the fixing elements 6, 7 and the resilient clamping elements 10, to be substantially perpendicular to one another. By using a sol- Chen fastener 4 together with an electrical Anschluß¬ terminal 1, it is therefore possible to clamp the terminal 1 not only by means of the fixing elements 6, 7 with the opposite inner edges 8, 9 of the wall opening 5, but the electrical terminal 1 can in particular be clamped in the housing wall 2 with the inner edge 11 of the narrow side of the Wand¬ opening 5.

The fastening element 4 shown in Fig. 3 has a substantially U-shaped base body with a U-back 20 and two U-legs 21, 22, and a parallel to the body extending latching tongue 23. The ends of the two U-legs 21, 22 are each formed as a fixing element 6, 7 aus¬, and the resilient clamping element 10 is formed by the free end of the latching tongue 23 which is fixed with its foot portion 24 in the region of the U-back 20. The free end of the latching tongue 23 is formed as an outwardly facing oblique and slightly curved clamping surface 12, wherein on the clamping surface 12 a plurality of parallel Rip¬ pen 13 are provided.

The illustrated in Fig. 3 preferred fastener 4 is designed so that it can be used particularly well with an electrical terminal 1, which is to be arranged in a wall opening 5, the first inner edge 8, 9 and the further inner edge 11 substantially perpendicular aufein¬ other places. In generally rectangular wall openings 5, these are the long sides and the narrow sides running perpendicular thereto. In this case, in the installed state of the electrical terminal 1, the two U-legs 21, 22 flat against the first inner edges 8, 9 (= long sides) and the curved clamping surface 12 with their ribs 13 of the latching tongue 23 also flat against the further inner edge 11 (FIG. = Narrow side) of the wall opening 5 are pressed in the housing wall 2.

The fastener 4 of FIG. 3 further includes an actuating wedge 14 which is pivotally mounted at the free end of the U-leg 22. The actuating wedge 14 can be pivoted into a position such that it presses the fixing elements 6, 7 and the resilient clamping element 10 against the corresponding inner edge 8, 9, 11 of the wall opening 5 in the mounted state of the connecting terminal 1. The actuating wedge 14 thus fulfills the double Function, both the two U-legs 21, 22 and the latching tongue 23 to deflect so far that they are in the installed state of the electrical Anschlußklem¬ me 1 firmly pressed against the respective inner edge 8, 9, 11 of the wall opening 5 and the electrical terminal. 1 fix so securely in the wall opening 5 of the housing wall 2.

The ability to deflect the two U-legs 21, 22 depends da¬ of whether the fastener 4 is fixed laterally on the terminal housing 3 or inserted into a corresponding pocket 18 on the terminal housing 3. If the fastening element 4 is inserted into a corresponding pocket 18 on the terminal housing 3, the U-legs 21, 22 can generally only be deflected to a very limited extent. The fixation of the terminal 1 is then carried out essentially by the clamping element 10, which is pressed against the inner edge 11 of the narrow side of the wall opening 5.

Thus, the deflection caused by the actuating wedge 14 of the U-legs 21, 22 and the latching tongue 23 is permanently ensured in the assembled state of Anschluß¬ terminal 1, on the surface of Betätigungs¬ wedge 14 has a toothing 15 and on the surface of the actuating wedge 14 facing side of the fixing element 6 a corresponding Gegenver¬ toothing 16 is formed, which ensure a locking of the mounting wedge 14 in the installed state of the terminal 1.

In the actuating wedge 14 has a recess 25 is formed in the unlocking tool, not shown, for. B. the blade of a screwdriver, can be inserted, in the event that the locking of Betätigungs¬ wedge 14 is to be solved with the U-leg 21 so that the electrical An¬ terminal 1 again from the wall opening 5 in the housing wall 2 ent ¬ can be removed.
