Description

The invention relates to a clamp connector for clamping and electrical contacting a insertable in a plug-in contact body, such as an electrical conductor and / or a printed circuit board, wherein the clamping connector has a receptacle for the contact body and the receptacle is at least partially surrounded by a housing of the clamp connector, wherein the housing has a clamping wall which bounds the receptacle laterally, wherein the receptacle a Klemmkontaktfeder for clamping and contacting the contact body is adjacent, which is designed to be movable in the receptacle and which has a contact with the contact body movable contact surface and wherein a Klemmkontaktfederantrieb for movement the clamping contact spring is provided in or out of the receptacle.

Such a clamp connector is often used to connect an electrical contact body, for example a bare or stripped conductor end of a cable, via the clamp contact spring to a connection contact, for example a busbar. For this purpose, the contact body and the terminal contact are inserted into the receptacle of the terminal connector. Subsequently, the contact body is contacted and clamped by the clamping contact spring.

The currently available clamp connectors are designed quite complicated, which leads to high production costs in the high quantities in which the clamp connectors are usually produced. The aim of the invention is thus to provide a clamp connector which is simpler in design and therefore less expensive to manufacture, without resulting in sacrifices in the clamping or contactability.

This object is achieved according to the invention for the above-mentioned clamping connector in that the terminal contact spring and the housing are integrally formed as a monolithic component.

By clamping connector according to the invention fewer separate components are used, which lead to a higher space consumption in the terminal connector. With a separate clamp contact spring, which is fastened inside the housing, it may happen that the attachment is released or damaged by vibrations, for example, and the clamp contact spring is moved inside the housing. As a result, the pressing force of the clamping contact spring is reduced, whereby the clamped contacts can be released unintentionally. Furthermore, the production costs of the clamp connector are reduced by material cost savings and simplified assembly. Therefore, a clamp connector is provided by the clamp connector according to the invention, which allows a small and stable design with a small number of parts and small space.

The solution according to the invention can be further improved by the following advantageous developments which can be combined with one another and which can be combined with one another as desired.

According to a first advantageous embodiment, the monolithic component may be a stamped and bent part. As a result, a simple and inexpensive production of the monolithic component is possible. With the stamping and bending technology, the production of complex components is particularly efficient, especially for components with a strong bending component. The monolithic component may be formed from a metal sheet and have a constant wall thickness. Preferably, the monolithic component may be formed of spring steel, so that the housing is robust to the outside and the clamping contact spring is elastically deformable.

To ensure a simple construction, the clamping contact spring can be formed from a continuation of a wall of the housing. The clamping contact spring may be formed from a continuation of the clamping wall, or be formed from a continuation of the wall opposite the clamping wall. Thereby, the clamping contact spring can be moved easily and with little effort relative to the clamping wall or away from the clamping wall elastic. In a further advantageous embodiment, the clamping contact spring may be formed from a continuation of a Klemmkontaktfederantriebsvorrichtung.

The clamping contact spring may be bent in the direction of the housing interior, so that the bend creates a joint at the apex of the arc around which the clamping contact spring can be deflected elastically relative to a wall. Furthermore, the arc of the clamping contact spring at least partially form a wall of the housing and thus prevent the penetration of, for example, dust or other unwanted particles.

The clamping wall may limit the receptacle at a substantially 90 ° angle to the insertion direction. In this case, at least the pressing surface may be arranged in at least one position of the clamping contact spring on the side opposite the clamping wall side of the receptacle. As a result, the electrical contact body can be inserted into the receptacle and is located at a substantially 90 ° angle to the insertion direction between the clamping wall and at least the pressing surface of the clamping contact spring.

In a further advantageous embodiment, the pressing surface may be arranged on a protruding in the direction of receiving buckle. This ensures that the clamping contact spring contacts the contact body with the pressure surface and the way by which the clamping contact spring must be deflected so that it contacts the contact body, is reduced. Furthermore, the pressing surface may be arranged on a flat portion of the clamping contact spring. This makes it possible that the pressing force when clamping a contact body is distributed over a larger area and thus damage to the contact body by the concentration of the pressing force is avoided in a small area.

According to a further advantageous embodiment, the clamping contact spring may comprise at least two legs, wherein a leg adjacent to the receptacle and is provided with the pressing surface. Due to the design of the clamping contact spring with at least two legs, the elasticity of the clamping contact spring is increased because the clamping contact spring has an arc between the two legs, the apex serves as a hinge around which a leg can deform elastically independently of the other leg. The pressing surface may be arranged in a further embodiment on the arc between the two legs. The bow may be a bulge projecting into the receptacle or may be formed fluently out of the bulge. As a result, the pressing surface is arranged on a flat, blunt surface, so that the contact body or the clamping contact spring is not damaged by the terminals.

According to a further advantageous embodiment, at least one leg can have a substantially straight course, wherein the leg is provided with a drive surface against which the clamping contact spring drive movable towards the clamping contact spring or away from the clamping contact spring strikes at least in one position. The drive surface and the pressure surface can be positioned on different legs. In a further embodiment, the drive surface and the pressing surface can be arranged on the arc between the two legs.

In order to produce as compact a design as possible and a directed deflection of the clamping contact spring and the required biasing and pressing forces, one leg may be bent back in the direction of the other leg. Preferably, the legs may extend at least in sections substantially parallel to each other.

Depending on requirements and geometric conditions, the terminal contact spring may have a plurality of bends and arcs, so that a directed deflection of the terminal contact spring can take place. Furthermore, the bends and curves can produce the required biasing and pressing forces.

According to a further advantageous embodiment, the legs can be arranged at an obtuse angle to each other. The bent-back leg may be bent in the direction of the receptacle or else away from the receptacle.

In order to produce a more stable and stronger area, the clamping contact spring may be provided at least in sections with at least one bent or folded stiffening strap. The stiffening tab can be arranged on one leg and bent in the direction of the other leg.

In order not to increase the width of the clamp contact spring, the at least one stiffening tab can be arranged on a constricted tongue. As a result, despite the reinforcement by the stiffening strap, a compact clamp connector with a small construction is possible.

Preferably, the clamping contact spring may have at least two stiffening tabs which are arranged on different sides of the clamping contact spring. The section with the at least one stiffening strap can, according to a further advantageous embodiment, have a substantially U-shaped cross section. As a result, the section is symmetrical and the terminal contact spring is reinforced evenly.

According to a further advantageous embodiment, the clamping contact spring may comprise at least three folded or bent stiffening tabs which are arranged on different sides of the clamping contact spring. This increases the stability and strength of the clamp contact spring in the area with the stiffening strap.

The stiffening tab may be formed by a free end of the clamp contact spring. The stiffening tab may have according to a further advantageous embodiment, at least one further stiffening tab. According to a preferred advantageous embodiment, the stiffening strap may be provided with two further stiffening tabs, wherein the two stiffening tabs are bent over or folded over. Preferably, the stiffening tab, which is provided with a further stiffening tab, have a substantially U-shaped cross-section.

According to a further advantageous embodiment, the stiffening tab on a Leg be arranged and bent or folded in the direction of the other leg. Preferably, the stiffening tab may rest against the other leg. As a result, a force acting on one of the legs can be transmitted to the other leg and an elastic deflection of the one leg relative to the other leg can be avoided. Preferably, the stiffening tab stiffen the clamping contact spring at least on the drive surface and / or on the pressure surface, since the forces acting on the legs and lead to an elastic deflection of the legs relative to each other, are directed to these two surfaces. Furthermore, the force acting on the drive surface can be transmitted to the pressing surface, whereby a stable and firm clamping of the contact body is ensured.

In order to achieve optimum stiffening in the pressing surface and / or driving surface, the stiffening strap can be adapted to the contour of the gap between the legs. As a result, the stiffening tab presses evenly on the adjacent leg and a force acting on the leg force is evenly distributed to the stiffening strap. Furthermore, a local bending in a region where the stiffening tab is not applied and acts on a force prevented.

The pressing surface may be formed according to a further advantageous embodiment of a free end of the clamping contact spring. This allows a simple uncomplicated design with low material and space requirements.

According to a further advantageous embodiment, the clamping contact spring can close the receptacle in the insertion direction of the contact body. This prevents contaminants, such as dust, from entering the receptacle through an opening in the clamp connector. Furthermore, it is prevented that the contact body is inserted too deeply into the receptacle and protrudes from the clamping connector at the end remote in the insertion direction. The contact bodies to be contacted, such as, for example, a cable end and a busbar, can both be inserted into the receptacle in the insertion direction.

According to a further advantageous embodiment, the receptacle can penetrate the terminal connector in the insertion direction. This allows the user to insert the contact body to be contacted from the same end in the insertion direction in the receptacle or insert a contact body in the insertion direction and a contact body against the insertion of different ends in the recording. Therefore, the clamp connector can be used depending on the environmental conditions and needs of the user.

According to a further advantageous embodiment, the clamping contact spring may be designed to be self-locking clamping the contact body. As a result, the clamping contact spring can pinch the contact body by its spring force. Furthermore, the clamping contact spring can be deflected away from the clamping position by the clamping contact spring drive so that the contact bodies can be inserted into the receptacle. In the case of a self-locking clamping contact spring, the clamping contact spring closes the receptacle in the insertion direction in its undeflected state. By deflecting the clamping contact spring with the Klemmkontaktfederantrieb the clamping contact spring can be directed into an open position and the contact body can be inserted into the receptacle. In the undeflected state, no force from the Klemmkontaktfederantrieb acts on the drive surface, whereby a possible plastic deformation of the terminal contact spring is avoided by a continuous load of the Klemmkontaktfederantrieb.

According to a further advantageous embodiment, the clamping contact spring can be guided and held by the Klemmkontaktfederantrieb in the clamping position. Preferably, the Klemmkontaktfederantrieb strengthen the pressing force of the terminal contact spring. This ensures a secure and firm contacting of the contact body in the clamp connector.

According to a further advantageous embodiment, the clamping contact spring may have a turning point, around which the clamping contact spring can be deflected relative to the side wall. The transition point can be formed for example by a curvature of the terminal contact spring.

According to a further advantageous embodiment, the clamping connector may have a stop against which the clamping contact spring, preferably with its turning point, strikes so that the clamping contact spring deforms at the turning point around the stop in the deflection direction. This determines the position of the elastic deformation and prevents it from causing unwanted deformation. The stop may be formed, for example, as protruding into the housing interior at a substantially right angle to the direction of movement of the terminal contact spring protruding projection.

In order to enable a simple movement of the clamping contact spring, the Klemmkontaktfederantrieb can be introduced from the outside into the housing interior, wherein the Klemmkontaktfederantrieb has an operative point for driving the Klemmkontaktfederantriebs, which is actuated from the outside. For this purpose, a drive opening may be provided in the housing. The drive opening can be aligned with the receptacle or in a substantially right Be arranged angle for receiving. Preferably, the drive opening can be arranged parallel to the receptacle, wherein the drive direction is substantially parallel to the insertion direction. Thus, a simple and easy operation is possible.

The clamping spring drive may be, for example, a screw which is provided with an external thread, and the drive opening may have an internal thread. As a result, a movement of the clamping contact spring with a small force on the Klemmkontaktfederantrieb is possible.

According to a further advantageous embodiment, the screw may have a standard thread or a special movement thread with great increase. Due to the large pitch, a large adjustment path is achieved with a small revolution.

In order to avoid losing the Klemmkontaktfederantriebs, the drive opening may be provided with a bayonet guide. As a result, the Klemmkontaktfederantrieb remains stationary in both end positions, namely the clamping position and the fully open position in which no force acts on the drive surface by the Klemmkontaktfederantrieb.

In the clamping position, the pressing force can be effected by the spring force and amplified by the Klemmkontaktfederantrieb. If only the spring force is to act, the Klemmkontaktfederantrieb may have a stop which locks the movement in the drive direction, whereby no additional force by the Klemmkontaktfederantrieb is possible.

In the following, the invention will be explained in more detail by way of example with reference to preferred embodiments with reference to drawings. The illustrated advantageous developments and refinements are each independent of each other and can be combined with each other, depending on how this is necessary in the application.

1 shows a schematic perspective view of a clamp connector according to the invention 1 , In 1 . 3 and 4 A wall was removed to take a look at the inside of the clamp connector 1 to enable. 2 shows the in 1 illustrated clamp connector 1 in a not yet bent state.

The clamp connector 1 has a housing 2 with two end walls 4 and two side walls 5 on, in the bent state ( 1 ) two end walls 4 are arranged substantially parallel to each other and opposite and the side walls 5 each substantially at a right angle to the parallel end walls 4 are arranged and the end walls 4 connects with each other. The end walls 4 each lie in a yz plane and the side walls 5 are each arranged in an xz plane. This is done by the side and end walls 4 . 5 a housing 2 with a substantially cuboid housing interior 7 limited.

The clamp connector 1 has a recording 6 on that the clamp connector 1 in a plug-in direction e , which is substantially parallel to the z-direction, penetrates. An electrically conductive contact body 8th , such as a conductor end of a cable 10 , can in plug-in direction e in the recording 6 be introduced. Furthermore, another contact body 12 , for example a busbar 14 , contrary to the insertion direction e or in a plug-in direction e be introduced into the recording.

The recording 6 becomes laterally opposite to the x-direction at a substantially right angle to the insertion direction e from the front wall 4 limited, the end wall 4 as a clamping wall 16 serves, to which the contact bodies 8th . 12 can be clamped.

The recording 6 has one in the insertion direction e for the contact body 8th front opening 18 on, to which a drive device 20 adjacent in the x direction. The drive device 20 is located in an xy plane, the housing closes 2 in z-direction and has a the driving device 20 in the z-direction penetrating drive opening 22 on.

In the drive opening 22 is a clamping contact spring drive 24 introduced. The clamping contact spring drive 24 is a screw in this embodiment 26 with an external thread 27 is provided and their longitudinal axis 28 essentially parallel to the insertion direction e runs. The drive opening 24 is provided with an internal thread, so that the screw 26 by operation of a screw head drive 30 in the insertion direction e in the case 2 in or against the insertion direction e out of the case 2 can be moved out.

The clamping wall 16 opposite end wall 4 is with a in the unbent state extending in the z-direction continuation 32 provided, from the after bending a Klemmkontaktfeder 34 is shaped.

It is in this embodiment of the clamp connector 1 around a stamped bent part, so that the housing 2 and the clamp contact spring 34 in one piece as a monolithic component 35 are formed.

As in 1 can be seen, is the terminal contact spring 34 in the z direction in the housing 2 bent in so that the clamp contact spring 34 in x-direction on the picture 6 , opposite the clamping wall 6 lying, adjacent. The resulting first arch 36 forms a bottom of the housing 2 in z-direction partially closes and on the recording 6 adjacent in the x direction. The first bow 36 deflects the clamp contact spring 34 at substantially 180 ° into the housing interior 7 around. After the first bow 36 the clamp contact spring extends 34 with a run-on slope 38 opposite to the x and z direction into the housing interior 7 , The clamp contact spring 34 has one in the receptacle 6 projecting vaulting 40 on, at a substantially parallel to the z-direction extending section 42 between the run-up slope 38 and the vault 40 borders. The vault 40 is through one for recording 6 directed curvature 44 on to the vault 40 directed end 46 of the section 42 educated. The clamp contact spring is at the vault 40 in from the recording 6 turned away direction by substantially 180 °, so that the clamping contact spring 34 a second bow 48 which has two legs 50 . 50 ' the clamp contact spring 34 connects with each other.

The thigh 50 is adjacent to the recording in this embodiment 6 on and the thigh 50 ' is from the recording 6 away. The thigh 50 ' extends with a straight section 52 obliquely in the x- and z-direction extending from the clamping wall 16 opposite end wall 4 ,

At his from the second arch 48 distant end 54 points the thigh 50 ' a stiffening strap 56 on, which is about 90 ° towards the thigh 50 is folded and on the thigh 50 is applied. To allow the folding, the clamping contact spring has 34 a folded edge 58 on, passing through a groove 60 between the thigh 50 ' and the stiffening strap 56 is defined.

The stiffening strap 56 is with laterally projecting wings 62 provided, which also fulfill the task of a stiffening strap, as explained later. The wings 62 are each bent at substantially 90 ° in the direction of the second arc, so that the stiffening tab 56 has a substantially U-shaped cross-section, and are also on the leg 50 at. The contour of the wings corresponds to the contour of the gap between the two legs 50 . 50 ' so the stiffening tab 56 evenly both thighs 50 . 50 ' contacted.

On the in the direction of the recording 6 projecting vaulting 40 is a pressing surface 64 arranged when deflecting the clamp contact spring 34 the contact body 8th contacted. This will be the contact body 8th . 12 in the clamping position (not shown) between the pressing surface 64 and the clamping wall 16 trapped.

The thigh 50 ' closes immediately to the bow 48 with the straight section 52 at. The clamp contact spring 34 is arranged so that the Klemmkontaktfederantrieb 24 at the transition from the bow 48 and the straight section 52 of the thigh 50 ' with an outer edge of the end profile 66 strikes. The of the Klemmkontaktfederantrieb 24 contacted area of the clamping contact spring 34 is the driving surface 68 , at which the force, by the Klemmkontaktfederantrieb 24 is generated on the terminal contact spring 34 is transmitted. By moving the clamp contact spring drive 24 in the insertion direction e will the force acting on the drive surface 68 works, increases. The stiffening strap 56 on the thigh 50 stops, prevents a deflection of the leg 50 ' around the second arch 48 relative to the thigh 50 , The power comes through the stiffening strap 56 on the thigh 50 transmitted and the terminal contact spring 34 becomes a transfer point 70 that of the vertex 72 of the first bow 36 is formed, towards the reception 6 deflected out.

In the deflected position (not shown) are the contacts to be contacted 8th . 12 between pressure surface 64 and clamping wall 16 compressed. The stiffening strap 56 increases the strength and stability of the clamp contact spring 34 at the pressure surface 64 so that the thigh 50 not the second bow 48 relative to the thigh 50 ' in Direction of the recording 6 can be deformed away. The clamping contact spring drive 24 prevents the return of the terminal contact spring 34 from the recording 6 path. The stiffening strap 56 serves to force on one leg 50 . 50 ' acts on the other thigh 50 . 50 ' to transfer and deforming a thigh 50 . 50 ' relative to the other thighs 50 . 50 ' to prevent. The shape of the stiffening strap 56 is at the gap 74 between the two thighs 50 . 50 ' adjusted and lies evenly on both thighs 50 . 50 ' at.

Because of the case 2 and the clamp contact spring 34 in one piece as a monolithic component 35 are formed, a small space is claimed, since no further components are necessary, the terminal contact spring 34 in the case 2 to fix. Furthermore, the production and assembly of the terminal connector 1 simplified, whereby the production costs are reduced, since the clamp connector 1 can be produced simply by means of stamping and bending technology.

In 3 and in 4 are further embodiments of a clamping connector according to the invention 1 shown.

Unlike the in 1 illustrated embodiment of the clamp connector 1 is the clamp contact spring 34 in the in 3 illustrated embodiment of a running in the z direction continuation 32 the clamping wall 16 shaped. The clamp contact spring 34 is in the housing interior 7 bent and thus closes the recording 6 in the insertion direction e , As a result, the contact body to be contacted only in the insertion direction e in the recording 6 be introduced. From the first arch 36 the clamp contact spring extends 34 with a run-on slope running counter to the z-direction and in the x-direction 38 to the clamping wall 16 opposite end wall 4 , The run-up slope 38 forms a first leg 50 at its to the clamping wall 16 opposite end wall 4 directed end, the terminal contact spring 34 at an obtuse angle towards the recording 6 bent back.

The resulting second bow 48 beats with his head 72 at the clamping wall 16 opposite end wall 4 at. The bent-back second leg 50 ' the clamp contact spring 34 extends in a direction opposite to the x and z direction with a straight section 52 who with one in the recording 6 projecting vaulting 40 concludes.

The vault 40 forms a third bow 76 in which the free end 78 the clamp contact spring 34 at substantially 180 ° to the straight section 52 is turned back.

The clamping contact spring drive 24 beats immediately at the transition of the straight section 52 and the third bow 76 on a drive surface 68 at. The deeper the clamping contact spring drive 24 in the insertion direction e in the case 2 is introduced, the more the terminal contact spring deflects around a turning point 70 that of the vertex 72 of the second arch 48 is formed, toward the first leg 50 out. This is the straight section 52 always substantially vertical to the longitudinal axis 28 of the clamping contact spring drive 24 and contacts a larger area of the end profile 66 of the clamping contact spring drive 24 , causing the drive surface 68 is enlarged.

The straight section 52 has a comparison to the width of the remaining terminal contact spring 34 Tongue narrowed in the y direction 80 on, at their respective to the side walls 5 directed edges with a stiffening strap 56 which is at substantially 90 ° towards the free end 78 are bent. This indicates the straight section 52 a substantially U-shaped cross section. The stiffening tabs 56 extend at an acute angle from the second arch 48 facing end of the straight section 52 to the vault 40 and complete with a cone, with which they are evenly attached to the third arch 76 issue. Through the narrowed tongue 80 becomes the clear width of the clamp contact spring 34 when bending the stiffening tabs 56 not increased.

With the movement of the clamping contact spring drive 24 in a plug-in direction e becomes the second leg 50 ' and the transition point 70 towards the first leg 50 deflected. The curvature jumps 40 continue into the recording 6 so that they with their Andrückfläche 64 abuts against a contact and the contact between Andrückfläche 64 and clamping wall 16 clamps. The pressing force is caused by the Klemmkontaktfederantrieb 24 , its power through the stiffening tabs 56 efficiently transferred to the pressure surface, reinforced.

In 4 is a perspective view of another embodiment of a clamp connector 1 in which a side wall 5 removed.

In this embodiment, the clamp connector 1 with a contact body self-locking clamped designed terminal contact spring 34 shown. The clamp contact spring 34 is out of one of the clamp wall 16 opposite end wall 4 opposite to the z-direction extending continuation 32 shaped.

The clamp contact spring 34 is at a substantially obtuse angle from the clamping wall 16 opposite end wall 4 into the housing interior 7 bent and closes at the first arch 36 with a straight section running counter to the x and z directions 52 at. The clamp contact spring 34 has a thigh 50 up at an obtuse angle in the x and z directions to the straight section 52 is bent back. The thigh 50 extends opposite to the x- and z-direction in the recording 6 in and hits with his free end 78 on the clamping wall 16 at. Therefore, the clamp contact spring closes 34 the recording 6 in the insertion direction e in its undeflected position.

The clamping contact spring drive 24 beats at the second arch 48 at the straight section 52 facing side of the cone. By moving the clamp contact spring drive 24 in a plug-in direction e becomes the clamp contact spring 34 around a transshipment point 70 , from the vertex 72 of the first bow 36 is formed, deflected in the insertion direction. This beats the free end 78 no longer on the clamping wall 16 on and the contact body to be contacted in or against the insertion e in the recording 6 be introduced. For clamping the Klemmkontaktfederantrieb 24 contrary to the insertion direction e moves, causing the clamp contact spring 34 back to their starting position. At the same time the terminal contact spring hits 34 with her free end 78 that the pressing surface 64 forms on the contact body and clamps this between the pressure surface 64 and the clamping wall 16 one.

In the in 4 As shown embodiment, the pressing force by the spring force of the clamping contact spring 24 generated and not by the Klemmkontaktfederantrieb 24 strengthened. In the clamping state, no force acts from the clamping contact spring drive 24 on the drive surface 68 ,
