Description

The invention relates to a connector with an insulating material housing and a spring terminal connection in the insulating material housing for clamping an electrical conductor. The spring force clamping terminal is formed as a plane-spanning plate-shaped flat contact having a root portion from which protrude in two diametrically opposite directions each a pair of opposing Klemmkontaktabschnitte for clamping each of an electrical conductor or contact pin between a pair of such Klemmkontaktabschnitte. The insulating housing has opposite conductor insertion channels for insertion of the electrical conductors or contact pins to be clamped.

The invention further relates to a connector having an insulating housing and a spring clamp terminal in the insulating housing for clamping an electrical conductor, wherein the spring clamp terminal is formed as a plane-spanning plate-shaped flat contact having a root portion from which a terminal contact portion for clamping an electrical conductor protrudes.

DE 28 51 712 A1 discloses a connector for backplane wiring to electrical equipment having at least one contact member made of a flat stamping for solderless electrical connection and for supporting at least one insulated connector wire of the backplane. Trained as a flat stamped part contact part has two diametrically opposite plug-in connections, which are designed as a fork contact with a resilient leg with barbs.

DE 25 17 465 C3 discloses a connector with a formed as a flat stamped part contact part for connecting wires and with a two-piece insulating material. The connector housing has an opening for receiving the contact part and is closed with a separate cover. The lid has insertion openings for insertion of an electrical conductor, which open into the free space provided in the connector housing for receiving the contact part.

Based on this, it is an object of the present invention to provide a further improved connector with an insulating material and at least one designed as a plate-shaped flat contact spring terminal connection, which ensures a reliable contact with the electrical conductor to be clamped in a simple and compact design.

The object is achieved with the connector with the features of claims 1 and 11. Advantageous embodiments are described in the subclaims.

It is proposed that the conductor insertion channels of the insulating housing extend from the outside to at least the associated terminal contact portion. The insulating housing then has a slot-shaped contact receiving channel which intersects the conductor insertion channels. The plate-shaped flat contact is designed for insertion into this contact receiving channel and for fixing to the insulating housing.

The fact that the conductor insertion channels extend to at least the associated clamping contact portion of the flat contact, a reliable conductor guidance is ensured. The flat contact is then inserted into a contact receiving channel which intersects the conductor insertion channels. In this way, the flat contact is kept space-saving and safe in a relatively narrow contact-receiving channel and aligned with the conductor insertion channels and the electrical conductors or pins to be inserted therein. The contact receiving channel is usually narrower than the conductor insertion channels. Adjacent to the conductor insertion channels a narrow guide of the flat contact and in particular a guide resiliently movable parts of the Klemmkontaktabschnitte is ensured using the contact receiving channels.

An increase in spring elasticity with the least possible installation space succeeds with a plug connector in which the clamping contact section has a spring arm section and a rigid conductor contact section arranged at a distance from the spring arm section. The spring arm portion has a central root portion (root portion), an adjoining support arm extending opposite to the conductor insertion direction of an electrical conductor to be clamped to the terminal contact portion, a spring arc adjoining the support arm, and a contact arm adjacent to the spring arc, oblique to the conductor insertion direction aligned and movable relative to the support arm. The rigid conductor abutment portion also joins the root portion and extends opposite to the conductor insertion direction. The rigid conductor abutment portion carries on its side facing the spring arm portion side edge a contact projection.

With the help of relatively movable to the support arm contact arm, which adjoins the provided exclusively for this contact arm spring bow and support arm, is a curved Spring leg created, which has a relatively large elasticity due to a uniform stress distribution. Thus, it is possible without substantial increase in the space required in comparison with only short barb-bearing spring arms or protruding from a rigid section spring arms to clamp conductors with a larger conductor cross-sectional area.

For the purposes of the present invention, the indefinite article "a" is not understood as a number word. The connector can of course be multi-pole and have several such Federkraftklemmanschlüsse. All that is necessary is that the connector has at least one spring terminal connection. Accordingly, the spring force clamping connection has at least one clamping contact section.

In this case, a further clamping contact section may project from the root section in the opposite direction to the clamping contact section formed by the spring arm section and the rigid conductor contact section. The further clamping contact portion is then formed as a pair of spring-elastic movable spring arms with contact groups facing each other.

It is conceivable that a clamping contact portion of the first pair of opposing Klemmkontaktabschnitten is formed as a spring arm with a subsequent to the root portion support arm, adjoining the support arm spring bow and a subsequent to the spring bow contact arm. Thus, the space required can be reduced or the spring elasticity can be increased.

The support arm can have a tapering in the direction of the root portion to the spring bow section. The contact arm may have a tapering in the direction of the spring bow to the free end clamping portion. By these tapered portions of the support arm and the contact arm succeeds even more even stress distribution, which has a greater spring elasticity result.

If the spring contact portion opposite Klemmkontaktabschnitt is designed as a rigid Leiteranlageabschnitt, then the Federklemmkraft the Federarmabschnitts on the conductor abutment portion opposite side of the inserted electrical conductor or contact pin is transmitted to this and prevented by the rigid conductor portion prevents the electrical conductor or pin yields. For a good clamping force with high surface pressure is effected and the current can be dissipated by the electrical conductor over the rigid conductor plant section. The current paths are optimally shortened via the rigid conductor plant section in comparison to the current path via the spring arm section.

The conductor abutment portion may have at least one protrusion protruding into the conductor insertion channel. Thus, the contact of the voltage applied to the rigid conductor plant section electrical conductor is reduced to this at least one contact tip. This results in low contact resistances as the clamping force of the spring arm section is concentrated on the contact tips.

The Klemmkontaktabschnitte the second pair of opposing Klemmkontaktabschnitten can be designed as spring arms with contact points pointing towards each other. Such a pair of spring arms is particularly suitable for contacting contact pins, but can also be used for the electrically conductive contacting of electrical conductors and in particular of rigid, single-stranded conductors.

A pair of clamping contact portions projecting in a first direction of the flat contact may be wider than the pair of clamping contact portions oriented diametrically opposite the second direction in the second direction. By this reduced in the region of the second pair of Klemmkontaktabschnitten width of the flat contact of the flat contact in the insulating housing is locked to one side by the broadening in the direction of the first pair of Klemmkontaktabschnitten forms a stop in the insulating housing.

The slot-shaped contact receiving channel may have a step for forming a stopper for latching the flat contact inserted in the contact receiving channel. A portion of the flat contact acts together with the stage of a stop. By elastic short-term deformation of either the insulating material or preferably the flat contact during insertion of the flat contact in the contact receiving channel can be the flat contact past the stage. Subsequently, the insulating material back or the flat contact springs back so that the step of the slot-shaped contact receiving channel with the flat contact together forms a stop which prevents the flat contact from sliding out of the contact receiving channel.

Thus, for example, a rigid conductor abutment section together with the following after the intermediate root area adjoining spring arm, both of which are arranged on one side of the introduced electrical conductor or pins and their conductor insertion channels, are used as a latching arm with the the flat contact in the contact receiving channel locked to form a stop.

It is also conceivable that the flat contact is caulked to the insulating housing by deformation of the insulating material after insertion of the flat contact in the slot-like contact receiving channel. For this purpose, the insulating material is deformed into the contact receiving channel, so as to form a stop for securing the flat contact in the insulating material.

1 lets a longitudinal sectional view of a connector 1 with a one-piece insulating material housing 2 made of non-conductive plastic material. In the insulating material housing 2 is a spring clamp connection 3 used to clamp an electrical conductor from the left side in 1 and another electrical conductor or contact pin is formed from the opposite right side. The insulating material housing 2 has a first conductor insertion channel 4 extending from the left-hand outside face into the interior of the insulating housing 2 extends to a Klemmkontaktabschnitt and beyond. In the illustrated embodiment, the conductor insertion channel 4 a towards the interior of the insulating material 2 funnel-shaped tapered section 5 , In this way, the opening to the outside part of the conductor insertion channel 4 be wider than the conductor insertion channel in the region of the terminal contact portion to accommodate the electrical conductor together with Isolierstoffmantel in the wider area. The stripped free end of the electrical conductor to be clamped then enters the narrower section of the conductor insertion channel 4 introduced.

Similarly, the second conductor insertion channel has 6 , on the right, opposite frontal outside of the insulating material 2 lies and there from the insulating housing 2 opens out, a funnel-shaped tapered section 7 , Also this conductor introduction channel 6 extends so far into the interior of the insulating material 2 in that it goes to the terminal contact portion for one in this conductor insertion channel 6 inserted electrical conductor or pin protrudes and even extends beyond.

It becomes clear that the insulating material 2 furthermore a contact receiving channel which is open towards the left end side 8th that has the conductor introduction channel 4 cuts across its entire length. The contact receiving channel 8th extends at least to the narrower tapered end of the flat contact 3 and also cuts the second conductor entry channel there 6 at least over the partial length of the flat contact 3 ,

The slot-like contact receiving channel 8th is of its width (in the direction of view) to the width of the plate-shaped flat contact 3 adjusted to keep it on both sides. The flat contact 3 lies with its upper and lower end edges on the contact receiving channel 8th limiting Inner wall of the insulating material 2 over a portion of these front side edges.

The flat contact 3 has a root section 9 extending transversely to the conductor insertion direction L indicated by an arrow. The conductor insertion direction L is the direction in which an electrical conductor enters the first conductor insertion channel 4 or in the opposite direction in the second conductor insertion channel 6 is introduced. The conductor insertion direction L is by the extension direction of the conductor insertion channels 4 and 6 specified.

From this root section 9 each extends a pair of opposed Klemmkontaktabschnitte 10a . 10b , Which are designed for clamping each of an electrical conductor or a contact pin. The left pair of terminal contact sections 10a is from a rigid conductor plant section 11 and a conductor plant section 11 opposite spring arm section 12 educated. The spring arm section 12 has one at the root section 9 subsequent support arm 13 which extends opposite to the conductor insertion direction L. This is under extension direction of the support arm 13 understood the main extension direction, regardless of whether the support arm 13 is aligned exactly parallel or at a slight angle to the conductor insertion direction L. In any case, the support arm extends 13 not transverse or diagonal to the conductor insertion direction L. On the support arms 13 closes a feather bow 14 at. This feather bow 14 is the same as the support arm 13 only for the one spring arm section 12 provided a spring force for attaching itself to the spring bow 14 subsequent contact arm 15 To provide the contact arm 15 extends diagonally to the conductor insertion direction L in the first conductor insertion channel 4 into it. With this relatively long contact arm 15 and the adjoining spring bow 14 a clamping spring is provided in which a relatively large spring elasticity and a uniform stress distribution is ensured. The clamping force of the contact arm 15 is on the opposite rigid conductor plant section 11 aligned, on which rests an electrical conductor to be clamped. For the reduction of the contact surface between clamped electrical conductor and Leiteranlageabschnitt 11 protrudes at least one contact tip 16 from the spring arm section 12 facing front side edge of the conductor plant section 11 from. This will over the Federarmabschnitt 12 applied to a clamped electrical conductor clamping force on the contact tips 16 concentrated and thus increases the surface pressure and reduces the contact resistance.

At the root section 9 continues to limit an overload stop 17 on, in the direction of the spring bow 14 points and between the free end of the contact arm 15 and the support arm 13 is arranged. This will be the possible deflection of the contact arm 15 in the direction of the support arm 13 by the stop on the overload arm 17 limited. The overload arm 17 forms together with the conductor plant section 11 in addition, a funnel-shaped conductor insertion section on the terminal contact portion 10a for a safe and accurate location and reception of one in the conductor insertion channel 4 introduced electrical conductor.

From the root area 9 protrudes a second pair of Klemmkontaktabschnitten 10b in the direction of the frontal opening of the second conductor insertion channel 6 from. This pair of clamp contact sections 10b is narrower than the first pair of terminal contact sections 10a executed. When inserting the flat contact 3 in the contact receiving channel 8th , which rejuvenates accordingly, is thus characterized by this taper and a corresponding bevel 18 in the interior of the insulating material 2 a stop for the flat contact 3 formed and this in the direction of the second conductor insertion channel 6 in insulating material 2 established.

The second pair of clamp contact sections 10b has two opposing spring arms 19a . 19b , the contact crests facing each other at the free end region 20 wear. These spring arms 19a . 19b are in the common root section 9 brought together by the spring force for Klemmkontaktierung one between the contact tips 20 lying electrical conductor or contact pin is provided. On the side of the second conductor entry channel 6 the electrical conductor or contact pin to be clamped there can be held in a mating connector (not shown). For latching such a mating connector has the insulating material 2 one in the direction of the mouth of the second conductor insertion channel 6 protruding latch arm 21 with a catch 22 ,

2 leaves a longitudinal sectional view of the connector 1 out 1 with an electrical conductor plugged in and clamped on the left side 23 detect. It becomes clear that the electrical conductor 23 with its Isolierstoffmantel 24 until the funnel-shaped rejuvenation 5 in the left conductor insertion channel 4 is introduced. The stripped end 25 the electrical conductor, however, is up to the root section 9 guided and adjoins this optionally spaced by a gap. This will be the contact arm 15 in the direction of the support arm 13 deflected and it becomes a spring force using the spring bow 14 on the clamped electrical conductor 23 exercised. The stripped end 25 of the electrical conductor 23 is done with the help of the spring arm section 12 on the contact points 16 of the rigid conductor plant section 11 pressed, so that a Stromübertragungsweg with low contact resistance between the stripped end 25 of the electrical conductor 23 and the rigid conductor plant section is ensured.

The width of this rigid conductor plant section 11 is greater than the width of the support arm 13 with the attached bow 14 and contact arm 15 , About the rigid conductor plant section 11 is provided by the provided width, a relatively large power line cross-section.

The section line BB cuts the insulating material housing 2 in the area of the contact receiving channel before a flat contact used.

The section line CC cuts the insulating material housing 2 in the area of the flat contact and the stripped end 25 of the inserted electrical conductor 23 , For the cut BB will open 4 and for the cut CC on 5 directed.

3 leaves a perspective view of the connector 1 out 1 and 2 detect. It becomes clear that the insulating material 2 a plurality of juxtaposed contact receiving channels 8th each with a flat contact inserted therein 3 Has. The contact receiving channels 8th are at least in the directly to the conductor insertion channels 4 adjacent area slit-like running with a width corresponding to the width of the plate-shaped flat contact 3 is adjusted. It becomes clear that the flat contacts 3 each span a plane and the slot-shaped contact receiving channels 8th adapted to this plane so that the plate-shaped flat contacts 3 each on both sides in the slot-shaped contact receiving channel 8th be fixed.

It can also be seen that the conductor introduction channels 4 also in the tapered area behind the funnel-shaped section 5 a larger diameter than the width of these conductor insertion channels 4 cutting contact receiving channel 8th in the at the conductor introduction channel 4 immediately adjacent areas. The contact receiving channels 8th can, as outlined in sections, have common sections. These widened sections are used to avoid accumulation of material in Isolierstoffgehäuse 2 , The contact receiving channels 8th can be opened as shown or closed by a cover not sketched.

4 leaves a cross-sectional view of the connector 1 out 2 in section BB with an inserted and clamped electrical conductor 23 at a nip and a free conductor insertion channel 4 detect. It becomes clear that the contact receiving channels 8th the conductor entry channels 4 cut and at least in the to the conductor entry channels 4 immediately adjacent areas are slit-like. There is the width of the contact receiving channels 8th to the width of the flat contacts inserted therein 3 adjusted so that the flat contacts 3 laterally on both sides of the insulating housing 2 in the contact receiving channel 8th being held.

5 leaves a cross-sectional view of the connector 1 out 2 on average CC recognize. This cut goes through the stripped end 25 an inserted electrical conductor 23 and includes a section through the support arm 13 and from this towards the conductor insertion channel 4 protruding contact arm 15 , Here it is again clear that the plate-shaped flat contact 3 each in a slot-like contact receiving channel 8th introduced and fixed there on both sides. The relatively narrow flat contact 3 in each case biases a plane parallel to the slot-like contact-receiving channel 8th lies. The resilient contact arm 15 is in this plane in the direction of the conductor entry channel 4 movable. The support arm 13 lies with its upper narrow front side edge on the narrow inner wall of the contact receiving channel 8th at least in sections, and is therefore based there.

6 leaves a side view of the plane in the form of a spanning plate-shaped flat contact 3 recognize trained spring terminal connection. The flat contact 3 can be punched out of a sheet metal part, for example. It is clear that the rigid conductor abutment section from the root section 9 in a first flight in the lower area in one direction and a spring arm 19b protrudes in the diametrically opposite direction.

Opposite to the spring arm 19b is another spring arm 19a arranged, which is approximately parallel to the lower spring arm 19b extends so that the two spring arms 19a . 19b together form a kind of tulip contact or fork contact. The two spring arms 19a . 19b are in the root section 9 merged, with the spring arms 19a . 19b from the root section 9 starting to rejuvenate first.

Opposite of the rigid conductor plant section 11 is the spring arm section 12 arranged at a distance from it. The spring arm section 12 is from one of the root section 9 protruding support arm 13 , an adjoining spring bow and a to the spring bow 14 subsequent contact arm 15 formed, which is the free end of the spring arm section 12 forms. The contact arm 15 has in the illustrated embodiment, a length which is greater than the gap or Distance between the rigid conductor plant section 11 and the support arm 13 is. The contact arm 15 is at an acute angle diagonally extending to the rigid conductor plant section 11 in the direction of the root section 9 aligned.

It is clear that the support arm 13 starting from the root section 9 in the direction of spring bow 14 is tapered conically. Also the contact arm 15 tapers off the spring bow 14 towards the free end of the contact arm 15 out. This achieves a uniform stress distribution and an improved greater elasticity of the spring arm section 12 provided.

7 leaves a perspective view of the flat contact 3 out 6 detect. It becomes clear that the flat contact 3 plate-shaped with a much smaller width than length and height. The material thickness of the flat contact 3 is approximately in the range of 1 mm to 5 mm and preferably in the range of about 2 mm +/- 1 mm.

From this representation it becomes again clear that the overload stop 17 in the space between the support arm 13 and the contact arm 15 protrudes. At a deflection of the contact arm 15 in the direction of the support arm 13 this meets with its free end on the overload stop 17 so that a further deflection and thus a connected risk of plastic deformation is prevented.

8th leaves a side view of the flat contact 3 out 6 and 7 with attached electrical conductor 23 detect. Here again it becomes clear that the electrical conductor 23 with its stripped end 25 only on the contact points 16 of the rigid conductor plant section 11 rests. The of the spring arm section 2 on the electrical conductor 23 exerted clamping force is thus on the contact tips 16 concentrated. The rigid conductor plant section 11 has a sufficient width and transition to the root area 9 so that it does not give way resiliently or bends when the clamping force by the Federarmabschnitt 12 on the electrical conductor 23 is exercised.

It is also recognizable that the contact arm 15 with its sharp-edged free end on the stripped end 25 of the electrical conductor 23 rests and is in this end 25 possibly digested. When exerting a tensile force on the electrical conductor 23 hooked the stripped end 25 on the contact arm 15 so that the electrical conductor 23 on the flat contact 3 is secured.

Disconnecting and removing the electrical conductor 23 from the flat contact 3 can be achieved when the terminal contact by the contact arm 15 is lifted with an operating tool. Optionally, this can be done relative to the insulating material housing 2 movable actuator in the insulating material 2 be installed. It is also conceivable that an actuating tool, for example in the form of a screwdriver in the contact receiving channel 8th is introduced. This can do this as in the 3 to 5 sketched one to the contact arm 15 have a leading disseminating area.

9 leaves a side view of the flat contact 3 with a to the spring arm section 12 clamped electrical conductor 23 and an opposite second electrical conductor 26 detect. This second electrical conductor 26 can also be designed as a contact pin. It is envisaged the second electrical conductor 26 or contact pin in through the two opposing spring arms 19a . 19b to clamp the formed contact tulip.

This is going out 10 more clearly, the one perspective view of the flat contact 3 out 9 with the two electrical conductors 23 . 26 shows. It becomes clear that the electrical conductors 23 . 24 in opposite directions in the flat contact 3 be plugged in. For each of these electrical conductors 23 . 26 In each case a pair of opposing contact portions is provided. On the left side is the pair of terminal contact portions of the spring arm section 12 and the rigid conductor plant section 11 educated.

On the diametrically opposite side is the pair of Klemmkontaktabschnitten from the two opposite spring arms 19a . 19b educated.

From all the illustrations it becomes clear that the flat contact 3 with its Klemmkontaktabschnitten, ie the spring arms 19a . 19b , the rigid conductor plant section 11 and the spring arm section 12 with the support arm 13 , the spring bow 14 and the contact arm 15 are arranged on a common plane and the thickness of the flat contact 3 at this level, ie the extent of the flat contact 3 perpendicular to this level is relatively low.

11 leaves a longitudinal sectional view through the connector 1 out 2 with additional mating connectors 27 detect. The mating connector 27 has an insulating material housing 28 with a plug-in opening 29 at the free front end. The contour of this plug-in opening 29 is to the contour of the insulating material 2 of the connector 1 adapted to the free end of the plug insulation housing 2 in the plug-in opening 9 insert. In the plug-in opening 29 protrudes the stripped free end 25 of the second electrical conductor to be clamped 26 into it, over part of its length in a ladder receiving opening 30 is guided. When attaching the mating connector 27 on the connector 1 this will be in the plug hole 29 protruding free stripped end 25 in the conductor entry opening 6 of the connector 1 led in to the contact points 20 the spring arms 19a . 19b to be clamped.

To the mating connector 27 on the connector 1 to lock, is on the insulating housing 28 a snap tab 31 present, which has a detent opening 32 limited. The snap tab 21 of the connector 1 is in this latching opening 32 led in and with the help of the catch 22 and the snap tab 31 latched to form a stop.

For fixing the electrical conductor 26 or contact pin on the insulating material 28 of the mating connector 27 Optionally, it may be provided that the electrical conductor 26 on the insulating housing 28 is caulked. For this purpose, opposing and in-flight tool receiving openings 33a . 33b present to the stripped end of the inserted electrical conductor 26 to lead. By inserting a tool into one or both of these tool receiving openings 33a . 33b can the electrical conductor 26 be deformed so as to pull out the electrical conductor 26 from the insulating material housing 28 to prevent.

12 lets a longitudinal sectional view through a slightly modified connector 1 detect. For the embodiment of the flat contact 3 and the insulating housing 2 with the slot-like contact receiving channel 8th can be made to the previous statements. The flat contact 3 is in the insulating housing 2 after insertion into the front open contact receiving channel 8th caulked. For this purpose, the insulating material 2 at least one point to form a locking projection 34 deformed. This is a sliding out of the flat contact 2 from the slot-like contact receiving channel 8th prevented. On the diagonally opposite side is the ramp 18 present, the flat contact 3 in this direction on the insulating housing 2 guaranteed.

13 leaves an embodiment of the connector 1 detect. Again, essentially to the previous embodiments for the formation of the insulating material 2 and the flat contact 3 to get expelled.

In contrast to the previous embodiments, the flat contact 3 in the insulating housing 2 with the help of a step 35 secured. This level 35 forms a stop for the in the contact receiving channel 8th inserted flat contact 3 connected to the front end of the rigid conductor abutment section 11 through the stage 35 is secured against being pushed out against the Leiterereinsteckrichtung L.

To the flat contact 3 at the stage 35 can lead past during the insertion process, the insulating material 2 be elastically deformed. It is also conceivable that the rigid conductor plant section 11 opposite to the contact points 16 a dent 36 Has. This indentation 36 can be up to about the root section 9 extend. Thus, the flat contact 3 without deformation of the insulating material 2 initially due to the indentation 36 reduced width so far in the contact receiving channel 8th be pushed into that in the last step only the free end of the rigid conductor plant section 11 taking advantage of the spring elasticity of the opposite in the spring bow 14 transition end of the support arm 13 at the stage 35 is passed.

This can be done by a to the outside of the insulating material 2 directed bevel 37 get supported.
