Description

The invention relates to a housing feedthrough connector with an insulating material housing, in which at least one receiving chamber for receiving an electronic component is introduced.

Such housing feedthrough connectors are used, for example, in the form of conductor terminals with conductor terminal connections lying opposite each other, which are each connected to one another via a busbar extending in the longitudinal direction of the conductor terminal. Such a conductor terminal is then used in the form of a wall feed-through terminal for insertion into a breakthrough of a housing wall. Housing feedthrough connectors are used with any type of electrical connectors, e.g. B. realized as electrical connectors or as terminals. Such housing feedthrough connectors often have to be connected to electronic components such. B. capacitors, in particular suppression capacitors, chokes, filters or the like are provided. In the following, an electronic component is understood to be a single active or passive component or an interconnection of individual components to form a higher-order functional unit, which in turn is then provided as a potted multipart component, as a circuit on a printed circuit board or in some other way.

From the EP 0 507 062 A2 is a connector strip with multiple, built in an insulating material connector pins known. To shield against Electromagnetic interference is the connector strip with a shield and for the suppression of conducted electrical interference with chip capacitors. The chip capacitors are mounted on a printed circuit board inserted directly into the connector strip.

In a comparable way is from the EP 0 411 807 B1 an electrical connector with a capacitor electrically connected to a grounding plate and terminals of the Ver binder known. The at least one capacitor is connected via L-shaped connectors with contact pins of the electrical connector, for. B. electrically connected by soldering.

US 4,804,332 A discloses a comparable electrical connector in the form of a plug with filter elements integrated therein. These filter elements are soldered via contact lugs with contact pins of the connector.

EP 1 415 370 B1 discloses a receptacle with an insulating housing having a plurality of electronic component receiving cavities and arranged in the housing conductive terminals and a grounding plate. In the cavities conductive springs for making electrical contact with the ground plate are arranged.

In contrast to housing feedthrough connectors, other types of electrical appliances are known, which can be latched as terminal blocks for a mounting rail and have a receiving shaft for receiving an electronic plug-in module. For example, this is off DE 10 2006 034 164 A1 a multi-pole lightning current and surge arrester in terminal block design known, which consists of a base part as a feed-through terminal and an insertable into the base part plug-in module with protective elements. The base part has spring contacts for electrically contacting the respective plug-in module. A ground contact is made by spring contact of a carrier of the Bottom part formed with the support rail.

Based on this, it is an object of the present invention to provide an improved housing feedthrough connector.

This object is achieved with the housing feedthrough connector having the features of claim 1. Advantageous embodiments are described in the subclaims.

In a housing feedthrough connector with an insulating housing, in which at least one receiving chamber is accommodated for receiving an electronic component, it is proposed that the housing feedthrough connector has at least one housing contact element, which is accommodated in the insulating material, in an associated receiving chamber for electrically conductive contacting a terminal contact of a extends in the receiving chamber accommodated electronic component and has a projecting out of the insulating housing contact portion for electrically contacting a housing wall in a state inserted in the opening of the housing wall of the housing feedthrough connector.

For a housing feedthrough connector, it is thus proposed to lead at least one housing contact element outwardly from a receiving chamber in order to electrically contact a housing wall with a contact section accessible with at least one section outside the insulating housing, when the housing feedthrough connector is inserted into an opening of the housing wall. By forming a receiving chamber in the insulating housing which is at least partially surrounded by walls of the insulating housing, an electronic component can be used protected in the receiving chamber. This electronic component can then with low impedance path with the Housing contact element are electrically conductively connected and when inserting the housing feedthrough connector in a housing wall opening on the shortest impedance path with the housing wall in electrically conductive connection. Thus, the EMC properties (electromagnetic compatibility) of the housing feedthrough connector are significantly improved with a simple compact design. This is achieved in particular by the best possible reduction of the track resistance between the electrical component and the housing contact element.

By integrating housing contact elements into an insulating housing with contact section protruding from the insulating housing, a reliable and simple electrical contacting of a housing wall is achieved when the housing feedthrough connector is inserted into a housing wall opening.

Particularly advantageously, the at least one housing contact element is formed as a spring clip with two opposite and by spring force for clamping a designed as a contact leg terminal contact of an electronic component against each other acting and connectable with a leg spring bow. The first clamping leg projects out of the insulating housing with a bend arranged between the spring bow and the free end of the first clamping leg. The spring clip is located with the bend in the inserted into a breakthrough of the housing wall state of the housing feedthrough connector under spring force on the housing wall. The clamping legs can move relative to each other under spring force on each other to clamp a terminal contact, for example by a clamping leg resting under spring force under a busbar piece or the insulating material and the other clamping leg (almost free) is movable.

The housing wall is thus for contacting the housing contact elements and the terminal contacts of the electronic components clamped thereto are used equally. In this way, sounding for electromagnetic compatibility (EMC) can be realized in a reliable and simple manner in which the connection contacts of the electronic components come to rest in the region of the opening of the housing, so that the impedance path is advantageously shortened further.

When inserting the housing feedthrough connector into a housing wall opening, the housing feedthrough connector is fixed in the housing wall with the aid of the clamping section, which bears against the housing wall, of the resilient at least one housing contact element. The formation of the housing contact elements as a spring clip has the advantage that the voltage applied to the housing wall clamping portion through this housing wall down towards the interior of the conductor terminal, d. H. is displaced in the direction of the receiving chamber and thus the force applied to the clamped terminal contact spring force is increased. If the housing feedthrough connector is not yet inserted into the housing wall opening, the at least one housing contact element is biased only by its own spring force, so that a substantially force-free or low-force insertion of the terminal contact of an electrical component is made possible. During insertion of the housing feedthrough connector into a housing wall opening, an automatic contacting of the housing contact element with the associated terminal contact or the transition from Vorkontaktierung when inserting the terminal contact in the Endkontaktierung with increased contact force, which is applied to the clamped terminal contact.

In an alternative embodiment, which may also be combined with the above-described embodiment of a spring clip by providing various housing contact elements in an insulating housing, at least one housing contact element has a clamping contact with two by a clamping slot for receiving a contact leg of an electronic component spaced from each other fork tongues. The connection contact can be z. B. be formed in the form of a contact leg. Also, such a fork terminal contact allows a simple and reliable clamping of a terminal contact of an electronic component, which is introduced into the receiving chamber of the insulating material. Again, the two fork tongues are under spring force, which is applied by the fork root, protrude from the fork tongues, at the contacted terminal contact. In this embodiment, a subsequent loading (placement) of the terminal contact on a terminal contact of a previously recorded in the receiving chamber and used there electronic component allows.

Optionally, other types of contact for the terminals of an electrical component, such as cage tension, U-shaped, directly pluggable and inserted in a conductor insertion opening of a busbar clamping spring, screw-terminal connection, insulation displacement contact, soldering or the like are conceivable.

Even when using a terminal contact for the housing contact element electrical contacting of the housing wall is made possible. For this purpose, it is advantageous if a spring element connects to the fork tongues with the intermediate clamping slot in such a way that a spring contact portion of the spring element protrudes from the top of the insulating material and the spring contact portion is applied in the inserted in a housing wall state of the housing feedthrough connector under spring force on the housing wall.

Such a spring element may, for example, be a spring tongue extending away from the clamping contact region. This spring tongue does not necessarily have to be bent. However, it is particularly advantageous if the spring tongue is again bent with the free end in approximately the same direction as the clamping contact. This provides an insertion bevel. Hooking of the housing contact element on the housing wall when inserting the housing feedthrough connector into a housing wall opening is prevented in this way.

The housing contact elements are preferably connected in such a way that at least two housing contact elements arranged directly or indirectly next to one another in the width direction of the conductor connection terminal are connected to one another in an electrically conductive manner. This can be done either via the housing wall, by connectable with the Gehäuseklemmelementen electrical conductors or with the aid of Strombrückerelementen. In the case of the insertion of current jumper elements, the housing contact elements preferably have contact openings for receiving and contacting such current jumper elements. The current jumper elements can be latched in the contact openings, for example, as known from bridges, by means of spring tongues.

It is particularly advantageous if at least one bus bar is accessible from an associated receiving chamber for the electrically conductive contacting of a terminal contact of an electronic component which can be accommodated in the receiving chamber. With the aid of a bus bar extending at least partially into the receiving space, it is possible to continue electrically contacting the electronic component in the receiving chamber with the busbar in addition to contacting the housing contact element. This can be a direct or indirect electrically conductive contact. A connection contact, for example in the form of a contact leg, can then with the aid of a component contact element of the busbar directly to the busbar and additionally by means of the housing contact element with an adjacent housing wall or by transverse bridging with other housing contact elements or busbars be contacted. This has the advantage that the impedance path through the relatively direct connection of the connection contacts to the busbar z. B. is significantly minimized by a cooperating with the busbar contact element and by the relatively direct connection to the housing wall via the housing contact element.

For this purpose, it is particularly advantageous if the at least one bus bar has a component contact element for contacting a terminal contact element of a component which can be accommodated in the assigned receiving chamber. Such a component contact element may, for. B. as a plugged onto an associated bus bar spring clip with two opposing and by spring force to each other movable legs and a leg connecting the spring bow for clamping a running as a contact leg terminal contact of an electronic component may be formed. This makes it possible to clamp a contact leg as a connection contact to the busbar in a particularly advantageous manner. The spring clip with its two opposite clamping sections and a spring bow connecting the clamping sections is plugged onto an associated bus bar. The clamping sections are movable towards each other by spring force. In this way, it is achieved that the busbar is clamped with resting contact leg of an electronic component in the manner of a clip of the opposite clamping portions of the spring clip and thus contacted electrically conductive.

Such a spring clip is simple, inexpensive and space-saving to integrate in the receiving chamber and allows long-term stable electrical contacting of an electronic component.

It is also possible to realize the electrical contacting of the electrical component with the busbar by means of soldering contact or the like. For fixing a contact leg in an electronic component in a defined contact position and providing a predetermined contact surface for the contact leg, it is advantageous if the at least one busbar adjacent to an associated terminal contact, in particular a spring clamping element, a support wall, which is aligned with the associated contact element in that the contact element presses a contacted (eg clamped) terminal contact of an electronic component against this abutment wall. Such a plant wall can be realized for example by attaching an offset in the busbar.

The at least one busbar preferably forms a bottom surface bounding the associated receiving chamber. Thus, a stable support is provided for the electronic component, so that the electronic component directly or indirectly z. B. with an insulating liner resting on the busbar. It is conceivable that the electronic component is mechanically attached to this busbar.

Furthermore, it is advantageous if the busbars in the region of the associated receiving chamber, in particular in the region of the connection of the terminal contact, are bent or angled and protrude into the receiving chamber. This can be easily adapted to the clamping position for the terminal contact of the electronic component, d. H. a height compensation can be realized. The impedance path is reduced by the direct connection of the connection contact to the busbar and can be further minimized by the height compensation.

From an EMC point of view, it has proved to be advantageous if the electronic component with its terminal contact as close to the power rail and the electronic component itself with low Distance from the busbar is arranged. It has been found to be advantageous if between the busbar and the adjacent electronic component, a spacer element, in particular an electrically insulating intermediate plate, is arranged.

Furthermore, it is advantageous if the at least one housing contact element is arranged in the insulating material such that an electronic component contacted with the housing contact element can be positioned with its connection contacts in the state in the plane of a housing wall and in the opening of the housing wall in an opening of a housing wall , In this arrangement, at least one contact pin of an electronic component in the direction of the housing breakthrough or at least partially disposed within the Gehäusedurchbruchs. As a result, the track resistance is reduced as best as possible. When using a noise suppression capacitor as an electronic component so that the effective resonance frequency is significantly improved, which leads to the optimization of the filter properties in the intended frequency spectrum of the housing feedthrough connector.

A corresponding effect can also be achieved structurally if the at least one housing contact element is arranged in the insulating housing such that an electronic component contacted with the housing contact element can be positioned in the plane of a housing wall in the opening of the housing wall into which the housing feedthrough connector can be inserted.

The housing feedthrough connector may e.g. B. be designed as an electrical connector or as a conductor terminal. The insulating housing can be in one piece or in several parts.

In one embodiment of the housing feedthrough connector as a conductor terminal For example, the insulating material housing can be assembled from a plurality of separate insulating housing parts arranged directly next to one another in the manner of terminal blocks. Each insulating housing part preferably receives in each case a bus bar and has a laterally open receiving chamber. Thus, an electronic component can first be inserted from the side into the receiving chamber of the insulating housing part and contacted with an associated busbar of the insulating housing part. Subsequently, the Isolierstoffgehäuseteile be optionally combined with electronic components therein to form a compact conductor terminal.

For example, in a conductor terminal with a bus bar, two opposing conductor terminal connections may be disposed at two opposite end portions of the bus bar extending through the receiving chamber. By arranged between opposing Leitererklemmanschlüssen and adjacent to the busbar receiving chamber a compact construction of the conductor terminal is achieved.

The existing on the opposite sides of the respective busbar terminal connections are preferably designed as spring clamp connections. Such Federklemmanschlüsse can in Direktstecktechnik, z. B. by means of an O-shaped spring, which is inserted into a conductor bushing opening of the busbar, be realized by means of a cage tension spring, a coil spring, an insulation displacement connection or the like. To operate such a spring clamp connection, a lever or pusher can be installed as an actuating element in the insulating material. It is also conceivable, however, that in addition to the conductor insertion openings each actuating openings are introduced into the insulating material. In an alternative embodiment, the terminal connections can also be used as pin or socket connections for the realization of an electrical connector be executed in the form of a housing feedthrough connector.

The housing feedthrough connector is designed for passage through a housing wall and mounting in the housing wall and has particularly advantageous on the outside of the insulating housing at least one projecting wall abutment portion for abutment with the housing wall. After insertion of the insulating material in the housing wall of Wandanlageabschnitt is thus on the housing wall. The housing feedthrough connector can then be latched on the side opposite the Wandanlageabschnitt using at least one locking element. Such a latching element may be, for example, a separate latching latch (latched to the housing feedthrough connector). Then the housing wall is located between this latching bracket and the Wandanlageabschnitt.

FIG. 1 shows a perspective view of a first embodiment of a housing feedthrough connector 1 in the form of a conductor terminal. The conductor connection terminal is designed with a multi-part insulating housing 2. In this case, disc-shaped Isolierstoffgehäuseteile 2 a, 2 b, 2 c, 2 d, 2 e are provided in the manner of a terminal, which are adjacent to each other and arranged parallel to each other and connected to each other. On opposite sides, that is at the front 3 and the back 4 conductor insertion openings 5 and adjacent to this actuating openings 6 are introduced into the insulating housing 2. These conductor insertion openings 5 and actuating openings 6 lead to unrecognizable Federklemmanschlüssen in the interior of the insulating material. 2

Furthermore, it can be seen that at the top of the insulating material 2, a plurality of upper housing contact elements 7 are passed through openings in the insulating housing 2 and protrude from the surface of the insulating housing 2 at the top upwards. When inserting the trained as a housing feed-through terminal 1 conductor terminal by a Housing wall opening, it is then possible that a housing wall opening limiting housing wall edge rests on these housing contact elements 7 and thus an electrically conductive connection between the housing contact elements 7 and the housing wall is made.

The Isolierstoffgehäuse 2 has a in the illustrated embodiment, the housing feed-through terminal 1 completely encircling Wandanlageabschnitt 8. When inserting the housing feed-through terminal 1 in a housing wall opening the Wandanlageabschnitt 8 can be brought to bear against the housing wall adjacent to the housing opening. In order to secure the housing feed-through terminal 1 in the housing wall, on the side opposite the Wandanlageabschnitt 8 side with intervening housing wall, a locking element 9 z. B. placed in the form of a resilient clip on the insulating 2 and locked with this suitable.

FIG. 2 leaves a cross-sectional view through the housing feed-through terminal 1 FIG. 1 detect. It is clear that the housing feed-through terminal 1 is inserted into the housing wall opening 10 of a housing wall 11. The housing feed-through terminal 1 rests against the housing wall 11 with the wall abutment section 8 and is fixed on the housing wall 11 on the side opposite the wall abutment section 8 with the detent element 9.

It can also be seen that the housing wall edge 12 of the housing wall 11, which delimits the housing wall opening 10, rests on a bend 13 of an upper clamping element 7. The upper housing contact element 7 is designed as a spring clip (spring clamping element) with a lower clamping leg 14, an adjoining spring bow 15 and an upper spring leg 16. The bend 13 is located between the spring bow 15 and the upper clamping leg 16. It is clear that the free ends of the lower and upper clamping legs 14, 16 approximately parallel to each other aligned and provided for clamping a usable therebetween first terminal contacts 17a of an electronic component 18. By clamping the housing contact element 7 in the housing wall 11 through the immediately adjacent tapered housing wall edge 12 a secure contact of the first terminal contact 17a and the housing wall 11 is achieved.

In the exemplary embodiments, the connection contacts 17a, 17b are designed as contact legs. Conceivable, however, are other variants of terminal contacts, such as. simple pads that are not on both sides by spring clips, but e.g. unilaterally contacted by compression springs, or terminal lugs or similar ..

The electronic component 18 is installed in a receiving chamber 19, which is introduced into the insulating 2 and thus at least partially and preferably is surrounded on all sides by the insulating material.

The insulating housing 2 further has a number of bus bars 20, which are arranged one behind the other on a common plane. At the respective opposite end portions of the busbar 20 Leiterklemmanschlüsse 21 are provided, which are designed in the illustrated embodiment as directly pluggable spring terminal connections. For this purpose, a conductor insertion opening with these at least partially surrounding hole collar 22 and inserted into this conductor insertion opening of the busbar 20 U-shaped clamping spring 23 is formed in the end regions of the busbar 20 respectively.

To open the spring clamp connection 21 and release an electrical conductor guided through the conductor insertion opening 5 and clamped to the clamping spring 23, an actuating opening 6 is provided which leads to an associated clamping spring 23.

However, embodiments are also conceivable in which the clamping spring 23 in this U-shaped type or z. B. is operated as a cage clamp with the help of an actuating lever. The actuating lever would then be mounted in a manner known per se in the insulating material swivel-mounted.

It is clear that in the area between the two opposite Leiterklemmanschlüssen 21 a clamping point for clamping a lower terminal contact 17b is provided. For this purpose, a component contact element 24 in the form of a spring clamping element is placed on the busbar 20 from the lateral edge transversely to the longitudinal direction L of the busbar 20. The lower contact element 24 is also bent in a U-shape and has a lower abutment leg 25, a self-adjoining (not visible) spring bow and at least in a partial region approximately parallel to the abutment leg 25 extending clamping leg 26. The clamping leg 26 is bent so, that a second terminal contact 17b of an electronic component 18 rests on the busbar 20 is pressed by means of the clamping leg 26 against the busbar 20 and held there mechanically and electrically contacted.

To fix the position of the component contact element 24 on the busbar 20, the busbar 20 may have a fixing opening 27. This fixing hole 27 does not necessarily have to be open on both sides (through-hole), but may also be designed as a depression (depression or blind bore). On the bearing limb 25 of the component contact element 24, a fixing lug 28 projecting in the direction of the clamping limb 26 is provided for dipping into the fixing opening 27.

Furthermore, it becomes clear that the bus bar 20 is bent or bent in the direction of the second connection contact 17b in order to compensate for the height to provide for direct connection of the second terminal contact 17b to the busbar.

FIG. 3 leaves a cross-sectional view of the housing feed-through terminal 1 Figures 1 and 2 detect in the region of the connection of the connection contacts 17a, 17b of the electronic components 18. It is clear that the second terminal contacts 17b are pressed by the clamping leg 26 on the busbar 20 by spring force of the lower component contact element 24. It can also be seen that the lower component contact element 24 is formed in the manner of a U-shaped leaf spring with the abutting on the underside of the busbar 20 plant leg 25, the adjoining spring bow 29 and adjoining the spring bow 29 clamping legs 26. The free end 30 of the clamping leg 26 is bent upward to provide an inlet slope for insertion of a terminal contact 17b.

It can also be seen that the busbars 20 have plant walls A. The abutment walls A are formed by forming, e.g. Embossing, the busbars 20 formed in the connection area for the connection contacts 17b. The abutment walls A form a defined contact system or a stop for the connection contacts 17b, which are pressed by means of the clamping legs 26 against the associated abutment wall A and thus electrically contacted with the busbar 20.

It becomes clear from the sectional view of FIG. 3 Also, the case feed-through terminal 1 is composed of a plurality of insulating case parts 2a, 2b, 2c, 2d, 2e. The Isolierstoffgehäuseteile 2 a, 2 b, 2 c, 2 d, 2 e are disk-shaped in the manner of a terminal and directly adjacent to each other, arranged in the width direction B side by side and connected to each other.

In the insulating housing 2 receiving chambers 19 are formed for electronic components 18. For this purpose, accessible from the side of the individual Isolierstoffgehäuseteile 2a, 2b, 2c, 2d and 2e recesses in the Isolierstoffgehäuseteile 2a to 2e introduced. Thus, first, an electronic component 18 can be introduced into the recess of such Isolierstoffgehäuseteiles 2a to 2e and contacted with the respectively arranged thereon busbar with the aid of the lower component contact element 24 placed thereon or with the housing contact element 7 electrically conductive. Subsequently, the adjacent Isolierstoffgehäusehälfte 2a to 2e is placed on the associated adjacent Isolierstoffgehäusehälfte 2a to 2e and thus the receiving chamber 19 is closed. The receiving chambers 19 are made sufficiently large to allow a recording of electronic components of different sizes.

The Isolierstoffgehäusehälften 2a to 2e can in a conventional manner z. B. with the aid of protruding locking lugs and corresponding locking recesses latched together and optionally or additionally screwed together. It is also conceivable, however, a gluing or other non-detachable connection of the Isolierstoffgehäuseteile 2a to 2b with each other after installation of the desired electronic components 18 in the receiving chambers 19th

FIG. 4 leaves a perspective view of the housing feed-through terminal 1 FIGS. 1 to 3 detect. It is clear that the housing feed-through terminal 1 is guided in the form of a conductor terminal through the housing wall opening on the housing wall 11. It can also be seen that the housing feed-through terminal 1 rests against the housing wall 11 with a wall contact section 8 running all around so as to prevent further insertion of the housing feed-through terminal 1 in the longitudinal direction L of the housing feed-through terminal 1. On the side opposite the Wandanlageabschnitt 8 side with lying between housing wall 11 is a locking element. 9 placed in the manner of a clip on the Isolierstoffgehäuse 2 and locked with this. This prevents accidental removal of the housing feed-through terminal 1 from the housing wall 11.

FIG. 5 shows a perspective view of a second embodiment of a housing feed-through terminal 1. The structure essentially corresponds to the previously described embodiment according to FIG FIGS. 1 to 4 , However, it differs in the design of the housing contact elements 7. Although these housing contact elements 7 protrude with a bend 13 from an opening at the top of the insulating housing 2 out of this. In this embodiment, the housing contact elements 7 but are not designed as spring clamp elements, but have fork contact terminal connections, which will become more apparent below.

FIG. 6 leaves a cross-sectional view of the housing feed-through terminal 1 FIG. 5 detect. It is clear that the structure essentially of the housing feed-through terminal 1 from FIGS. 1 to 4 corresponds, so that reference is made to the above.

A difference, however, the embodiment of the housing contact elements 7 is. It can be seen that a fork-clamp contact 31 protrudes with its free end in the direction of the busbar 20 transversely to the longitudinal direction L of the busbar 20 and transverse to the width direction B. A first connection contact 17a of an electronic component 18 is then inserted into a clamp slot of the fork clamp contact 31 lying between two fork tongues and contacted with the fork tongues in an electrically conductive manner.

At the fork-clamp contact 31, a spring element 32 connects, which protrudes with a bend 13 from the top of the insulating housing 2 and for this purpose passes through an opening in the insulating 20 through. The spring element 32 can be designed as a simple, almost rectilinearly extending material flap or be formed as shown in the form of a bent spring. The illustrated embodiment with a spring-like bent spring element 32, in which connects to the upper bend 13, a spring bow 33 and a support leg 34, has the advantage that a secure electrical contacting of the housing wall 11 through between the bend 13 and on the Isolierstoffgehäuse second resting support leg 34 applied spring force is achieved.

The fork clamping element 31 can be subsequently inserted into the insulating housing 2 in order to contact a first terminal contact 17a of an electronic component 18 already located in an associated receiving chamber 19. For this purpose, the insulating housing 2 at the top slots S, in which the housing contact elements 7 are introduced.

FIG. 7 is a cross-sectional view of the embodiment of a housing feed-through terminal 1 of FIGS. 5 and 6 detect in the region of the connection of the connection contacts 17a, 17b of the electrical components 18. The design of the busbars 20 with the component contact element plugged thereon corresponds to the first embodiment according to FIG FIG. 3 , so that is referred to what is said there.

The housing contact elements 7, however, are corresponding FIG. 6 equipped with fork clamp contacts 31. The fork-terminal contacts 31 each have two leaving a clamping slot 35 spaced fork tongues 36a, 36b. The clamping slot 35 is widened conically towards the free end, in order in this way to provide an insertion bevel for an associated contact leg 17a. In a clamping portion of the clamping slot 35, an associated terminal contact 17a of an electronic component 18 is clamped between the fork tongues 36a, 36b and electrically conductively connected.

It can be seen that the housing contact elements 7 are electrically conductively connected to one another via transverse webs 37. The housing contact elements 7 and the transverse webs 37 are preferably made integrally from a sheet metal element. This integral contact piece consists of several on one level side by side with intermediate transverse webs 37 arranged housing contact elements 7 and is installed in the insulating material 2 of the conductor terminal.

FIG. 9 1 shows a cross-sectional view of a further embodiment of a conductor connection terminal 1 in the connection region of the connection contacts 17a, 17b of the electronic components 18. Unlike the embodiment according to FIGS. 7 and 8 the housing contact elements 7 are formed individually and not connected to each other in the transverse direction. In the illustrated embodiment, four separate housing contact elements 7 are installed independently of each other in the insulating housing 2 of the conductor terminal 1.

The rest of the embodiment of the housing feed-through terminal 1 corresponds to the previously described embodiments, so that reference is made to the relevant explanations.

FIG. 10 allows a perspective view of the four separate, arranged side by side on a plane housing contact elements 7 recognize. As in the previously described embodiment close to the fork-terminal contacts 31 spring elements 32 in the form of a U-shaped bent spring arm, whose upper bend 13 protrudes from the insulating material 2 as previously explained. In this way, the housing contact element 7 can be contacted with a housing wall 11 electrically conductive. In this regard, reference is made to the explanatory notes FIG. 6 directed.

FIG. 11 has a partial sectional view of a housing wall 11 with several recognize side by side grooves 38 and inserted therein housing contact elements 7 without a conductor terminal. The housing contact elements 7 are provided to be subsequently inserted into slots S on the upper side of an insulating housing 2 of a housing feed-through terminal 1.

It can be seen that the housing contact elements 7 are bent in a U-shape and have an upper connecting web 39, at whose ends opposite one another with a 90 ° bend fork clamping contacts 31 protrude downwards. The fork terminal contacts 31 each have in the manner described above, two spaced fork tongues 36a, 36b, which provide a clamping slot 35 for clamping a contact leg of an electronic component.

It can be seen that the housing contact elements 7 are inserted with their upper portion in the groove 38 and contacted with the side edges of the upper connecting web 39, the side walls of the groove 38 electrically conductive.

Again, the housing contact elements 7 are designed as fork terminal contacts whose fork tongues 36a, 36b protrude while leaving a respective clamping slot 35 in a receiving chamber 19 for electronic components. In the upper region, these housing contact elements 7 can be connected to one another in an electrically conductive manner by means of a busbar piece 20 extending transversely in the width direction of the housing feedthrough terminal 1. With the help of this busbar piece 38, the housing contact elements 7 are also held mechanically in the insulating housing 2 of the housing feed-through terminal 1.

FIG. 12 shows a longitudinal sectional view of the housing feed-through terminal 1 in partial section in the region of the housing contact elements 7. It is clear that the housing contact elements 7 are bent in a U-shape and have an upper connecting web 39, at its ends opposite each other with a 90 ° bend fork terminal contacts 31 protrude downward.

FIG. 13 leaves a top view of the housing contact elements 7 according to FIGS. 11 and 12 detect. It is clear that the upper connecting web 39 of the housing contact elements 7 each have openings 40 with which reinforce the spring clamping action of the side edges of the upper connecting web 39 when clamping in a groove 38. It can clearly be seen that the side edges of the upper connecting web 39 abut against the side walls of the associated groove 38 and thus contact them in an electrically conductive manner.

FIG. 14 shows a perspective view of a housing contact element 7 in the embodiment of FIG. 13 detect. It is clear that an oval-shaped opening 40 is introduced at the upper connecting piece 39 and two fork contacts 31 are arranged parallel to each other and project from the opposite ends of the upper connecting web 39 in the same direction from each other down.

FIG. 15 shows a side sectional view through a further embodiment of a housing feedthrough connector 1 in the form of a conductor terminal. This is similar to the one in FIG. 2 constructed housing feedthrough connector constructed and inserted into a breakthrough of a housing wall 11. In the receiving chamber 2, an electronic component 18 is accommodated in the form of a suppression capacitor. Between the electronic component 18 and the busbar 20 is a non-conductive intermediate plate 41. The electronic component 18 thus rests by the intermediate, non-conductive intermediate plate electrically isolated on the busbar 20. Such a non-conductive intermediate plate 41 as a spacer between the electronic component 18 and the busbar leads at a small distance of the suppression capacitor to the busbar 20 to improve the effective resonant frequency.

It is also clear that the connecting contacts 17a, 17b of the electronic component 18 designed as connecting legs lie in the plane of the housing wall 11. At least one of the contact legs of the suppression capacitor thus points in the direction of housing breakthrough and lies at least partially within this housing breakthrough. As a result, the track resistance is shortened as possible. However, this arrangement is dependent on the design of the electrical component 18. A decisive advantage is achieved if the position of the at least one terminal contact 17a, 17b is very close to the busbar 20 or very close to the adjacent housing wall of the housing aperture and the housing contact element 7 , This leads to a low track resistance and thus to a low-impedance connection to the housing wall 11 and the bus bar 20.

For filtering and dissipation of noise, the housing and the housing wall 11 are of course electrically conductive and e.g. made of sheet metal.

For a multi-phase package feedthrough connector, the impedances of the drain lines of the individual phases L1, L2, L3 and N should be as equal as possible in order to realize a uniform frequency response of all potentials.

FIG. 16 shows a side sectional view of a housing feedthrough connector 1 in the form of a conductor terminal. The embodiment is comparable to FIG. 15 with the difference that now the electronic component 18, ie the suppression capacitor is positioned in the plane of the housing wall 11 in the housing wall opening, in which the housing feedthrough connector 1 is inserted into the opening of the housing wall 11.

Incidentally, based on the comments on the embodiment FIG. 15 to get expelled.

FIG. 17 1 shows an embodiment of a case feed-through connector 1 in which a lead terminal connection is provided on one side (left side) and a connector terminal on the right side. For this purpose, a pin contact 42 is formed at the free end of the bus bar 20, which is surrounded by a plug contact opening 43 of the insulating housing 2.

Such a combination of conductor terminals on one side and connector terminal on the other side is conceivable for all above-described embodiments of a housing feedthrough connector and, in principle, independent of the specific design of the receiving chamber for an electronic component and the design of the at least one housing contact element and component contact element.

Instead of the illustrated pin contact 42 may of course also be provided a socket contact or another embodiment of a releasable contact of an electrical connector.

The FIG. 18 shows a sectional view of another embodiment of a housing feedthrough connector 1 in the form of an electrical connector recognize. In this embodiment, on the left side of a socket contact 44 and on the right side in turn, the pin contact 42 is made FIG. 17 available. The socket contact 44 and the pin contact 42 are each peripherally surrounded on all sides by a plug contact opening 43 which is formed by the insulating material 2.

In the illustrated embodiment, the bus bar 20 is bent down adjacent to the component contact element 24 below the electronic component 18 down to achieve in this way a clearance for the second terminal contact 17b of the electronic component 18 to the busbar 20. This ensures that the electrical connection of the electronic component 18 to the busbar 20 in a defined manner takes place exclusively via the component contact element 24.

FIG. 19 shows another embodiment of a housing feed-through connector 1 in the form of an electrical connector in the sectional view in the inserted in a breakthrough of a housing wall 11 state. In this case, the electrical component 18, starting from the housing contact element 7, is inserted diagonally downward in the direction of the busbar 20 into the receiving chamber 19 such that the first terminal contact 17a and the electronic component 18 are located substantially in the plane of the housing wall in the opening of the housing wall 11, when the case feedthrough connector 1 is inserted into the case wall opening as shown. The connection of the second terminal contact 17b to the busbar 20 is effected by displacing the component contact element 24 to the right end of the receiving chamber 19th

As a result, the transmissions of the bypass capacitor are further improved and optimized in terms of the design of the electronic component 18 in the form of an interference suppression capacitor. In the illustrated embodiments, the bus bar 20 is located on the right side diagonally upwards, so that the running as a pin contact of a connector free end also has diagonally upwards. The connector is thus accessible diagonally from above, which possibly facilitates the operation and saves space.

FIG. 20 omits a modification of the housing feedthrough connector 1 FIG. 19 Detect in the form of an electrical connector. There, the busbar 20 is lowered significantly below the electronic component 18 down to increase the receiving chamber 19 in the region of the opening in the plane of the housing wall 11 for receiving the electronic component 18. The electronic component 18 borders directly or preferably with intermediate insulating intermediate plate (not shown) to the busbar 20 at. In this case, the second connection contact 17b lies in the plane which corresponds to the plane of the busbar 20 adjacent to the depression with the component contact element 24 arranged therein. The second terminal contact of the electronic component 18 can thus be electrically connected to the busbar 20 by the shortest route. It has been found that this also leads to a significant improvement in the transmission by reducing the resistance of the web. The illustrated variants are to be selected depending on the design of the electronic component 18 and would be found to improve the transmission of bypass capacitors by different positioning of the bypass capacitors on a housing feedthrough connector 1, which is electrically connected to the housing wall 11 and the bus bar 20. However, the transmissions are essentially dependent on the impedances of the capacitor terminals to the housing contacts, the impedances of the capacitor terminals to the bus bar and the external terminals, as well as the position of the contact pins of the capacitor and the bypass capacitor itself with respect to the electrically conductive housing. The highest effective resonant frequency and thus the best filter in the planned frequency spectrum of an electrical housing feedthrough connector 1 is obtained when the bypass capacitor is arranged in the plane of the housing aperture and at least one terminal contact of the bypass capacitor in the direction of housing breakthrough or at least partially lies within this housing breakthrough. Every other component layer inevitably leads to a greater resistance to the web. The preferred position of the bypass capacitor with respect to the housing is thus essentially dependent on the design of the capacitor and its connection pins.

The first terminal contact of the electronic component 18 should be very close to the housing opening or the peripheral edge of the housing wall 11, on which the housing contact element 7 in electrically conductive contact with the housing wall 11 occurs, be. The position of the second terminal contact 17b, however, should be very close to the busbar 20. As a result, a low resistance rail and thus a low-impedance connection to the housing wall 11 and the busbar 20 is achieved.

The bypass capacitor itself should be arranged with a small distance to the busbar 20 optionally with electrically insulating washer.

Furthermore, it is advantageous if the position of the capacitor contact is very close to the outer terminals of the housing feedthrough connector. This also reduces the web resistance.

It is furthermore advantageous if the electronic component 18 is accommodated as completely as possible within the insulating housing of the housing feedthrough connector 1, in particular in the form of a capacitor, and is particularly preferably completely enclosed by the insulating housing 2.
