From this, an object of the present invention is to provide an improved conductor connecting contact element that sandwiches an electric conductor.

This problem is solved by a conductor connecting contact element having the characteristics of claims 1, 12 and 13. Advantageous embodiments are described in the dependent claims.
With respect to the conductor connecting contact element having the bus component and the tightening spring element, the tightening spring element is movably arranged on the bus component and the spring tongue piece has a contact portion, and the contact portion is on the bus component. It has been proposed that the tightening spring element is formed so as to abut and to open the tightening position by the movement of the tightening edge away from the tightening portion in the relative opening movement of the tightening spring element with respect to the bus component. Tongue.

The abutment on the spring tongue piece, in combination with the mobility of the tightening spring element, tightens the electrical conductor formed between the spring tongue piece and the bus component when the tightening spring element is moved in open motion. It is achieved that the tightening position is open. By this movement, the abutting portion reaches the abutting position or abutting position of the bus part, so that the further opening movement of the tightening spring element relative to the bus part is the spring tongue abutted on the bus part at this time. Lead the piece to an open movement. In this case, the tightening edge of the spring tongue piece is pulled away from the tightening portion of the bus component, thereby opening the tightening position that sandwiches the electrical conductor formed between the tightening edge and the tightening portion. To do.

In order to open the tightening position, the spring tongue piece cannot be moved directly by simply urging the tightening spring element fixedly attached to the bus component with an operating force. Rather, the lever action of the abutment on the spring tongue piece is utilized. In the opening motion of the tightening spring element, the abutment provides a fixation point and the spring tongue piece swings around the fixation point.

This provides a very compact, very easy and reliable conductor connecting contact element.
The contact portion of the spring tongue piece may be formed as at least one protrusion that protrudes laterally from the spring tongue piece that abuts on the edge of the attached ridgeline of the side wall portion of the bus component. At this time, the protrusion is easily formed, for example, integrally with the spring tongue piece.

The bus component may have a bottom portion and two side wall portions that project from the bottom portion and are spaced apart from each other. The tightening spring element then has a side wall supported by the side wall portion of the bus component and a first crossbar connecting the side walls. The spring tongue piece then projects from the crossbar towards the bottom portion in the intermediate space between the side wall portions of the bus component.

Interleaved side wall and bottom portions of the bus components provide a U-shaped conductor guide channel. The side wall portion of the bus component is further utilized to support the tightening spring element. This is done by supporting and guiding the side wall of the tightening spring element to the side wall portion of the busbar component. The first crossbar acts as a base portion for the spring tongue piece and at the same time provides an additional operating surface, which can be urged with an operating force for the opening motion of the tightening spring element.

The side wall may be coupled to another second crossbar spaced apart from the first crossbar. This further stabilizes the tightening spring element.
It is advantageous when the second crossbar is located on the same side as the first crossbar. This provides a dish-shaped tightening spring element, in which the spring tongue pieces project oppositely in the intermediate space between the crossbars and between the sidewalls of the tightening spring element. ..

The tightening spring element may have support fingers, which project from the tightening spring element and into the support opening of the bus component. At this time, the support opening may be present, for example, in the side wall portion of the bus component. Thereby, the tightening spring element is engaged with the bus component by the support finger and at this position is movably supported around the support finger forming the pivot shaft. This support fingerer can be formed integrally with the tightening spring element in an inexpensive and simple manner as it is cut out from the sheet material of the tightening spring element and provided from the surface.

The bus component may have contact projections formed from the surface of the bus component. The reduced contact surface is provided by the contact projection, the electric conductor to be sandwiched abuts on the contact surface, and the spring force of the tightening spring element is concentrated on the contact surface. In this way, the surface pressure is increased and the contact resistance is improved.

The contact protrusion may be formed as, for example, a contact tongue piece formed by cutting out from the bottom portion of the bus component. This has the advantage that the free end of the contact tongue piece forms the tightening edge, and the electrical conductor to be pinched is pinched and hooked on the tightening edge. This improves the tightening of the electrical conductor. Further, the formed contact tongue piece provides a funnel-shaped conductor introduction formed with a similarly obliquely extending spring tongue piece on the opposite side.

The generatrix component and the tightening spring element may each be a thin plate element having a U-shaped cross section. The thin plate elements bent into a U shape are then arranged on top of each other so as to form a closed cage around them. That is, the bus component bent into a U shape may enter the opening of the U shape tightening spring element, or vice versa. Thereby, the tightening spring element is supported by the bus component without twisting, and the side wall portions and side walls adjacent to each other provide a guide portion. The tightening spring element is then swung around the support shaft or floating bearing, or moved towards the bottom along the busbar component, or by a combination of bouncing and translational motion. It is possible.

The tightening spring element may be swingably supported by a bus component in a pivot bearing. At this time, it is advantageous when the shaft of the pivot bearing is located behind the freely movable end of the spring tongue piece when viewed in the extension direction of the spring tongue piece. The tightening spring element is then swingable around the axis of the pivot bearing, on the one hand. On the other hand, the spring tongue piece is brought into contact with the bus component by the contact portion in the opening motion. Therefore, the pivot bearing and abutment provide two fixation points that guide the spring tongue piece into open motion in further open motion to the tightening spring element.

The problem is that the tightening spring element is movably arranged on the bus component, and the bus component and the tightening spring element are thin plate elements whose cross sections are bent into a U shape, respectively, and are bent into a U shape. The lamella elements are also solved by being placed on top of each other to form a closed cage around them. Thereby, in principle, the electrical conductor can be introduced into the cage space of the extremely compact conductor connecting element and pinched at the tightening position, independent of the possible forms of the tightening position. The relative mobility between the tightening spring element and the bus component also allows the opening of the tightening position to remove the electrical conductor and, optionally, the closing of the tightening position to pinch the electrical conductor.

The cage has two sidewalls in which the bus components project from the bottom and are spaced apart from each other, and a tightening spring element joins the sidewalls and sidewalls supported by the sidewalls of the bus components. It can be formed by having a first crossbar to be formed.

The tightening spring element may have a spring tongue piece and be similarly movably located on the bus component. The spring tongue piece projects from the first crossbar toward the bottom portion in the intermediate space between the side wall portions of the bus component.

Also in this modification, it is advantageous when the bus component has contact protrusions formed from the surfaces of the bus component. The contact protrusion may be formed as a contact tongue piece formed by cutting out from the bottom portion of the bus component.

In this modification, the tightening spring element may also be swingably supported by the bus component in the pivot bearing, independent of the form of the tightening position. The shaft of the pivot bearing is, in this case, located behind the tightening position in the conductor insertion direction. Here, the pivot bearing may be formed by a support finger of a tightening spring element projecting into the attached support opening of the bus component.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings according to an embodiment.

FIG. 1 shows a perspective view of a conductor connecting contact element. FIG. 2 shows a side view of the conductor connecting contact element from FIG. FIG. 3 shows a vertical cross-sectional side view of the conductor connecting contact element from FIG. FIG. 4 shows a vertical cross-sectional view from FIG. 3 having an inserted electrical conductor in an open position. FIG. 5 shows a perspective view of the generatrix component of the conductor connecting contact element from FIG. FIG. 6 shows a perspective view of the tightening spring element with respect to the conductor connecting contact element from FIG.

FIG. 1 is a perspective view showing a conductor connecting contact element 1 formed in the shape of a basket from a bus component 2 and a tightening spring element 3. The bus component 2 is formed as a single component from a thin plate component. The bus component 2 has a bottom portion 4, and side wall portions 5a and 5b spaced apart from each other project from the bottom portion 4 on the side portions facing each other. The side wall portions 5a and 5b extend over substantially the entire length of the bottom portion 4. In this way, the bus component 2 has a U-shaped or trough-shaped cross section.

Similarly, the tightening spring elements 3 have side walls 6a, 6b facing each other, with the side walls 6a, 6b being mutually opposed by a first crossbar 7a in the anterior region and by a second crossbar 7b in the rear region. It is combined. In the intermediate space between the first and second crossbars 7a and 7b, the spring tongue piece 8 projects from the first crossbar 7a in the direction of the bottom portion 4 of the bus component 2. In this case, the spring tongue piece 8 is integrally formed with the first crossbar 7a.

It can be seen that the tightening spring element 3 is placed on the bus component 2 or that the bus component 2 is inserted into the tightening spring element 3. In this case, the side walls 6a and 6b are overlapped with the attached side wall portions 5a and 5b of the bus component 2 in pairs. As a result, the tightening spring element 3 is guided by the bus component 2. The tightening spring element 3 is relatively movable with respect to the bus component 2. From the side walls 6a and 6b, the support finger 9 projects into the attached support opening 10 of the side wall portions 5a and 5b of the bus component 2. A support finger 9 and an accessory support opening 10 located below the second crossbar 7b provide a floating pivot bearing. The front support finger 9 existing below the first crossbar 7a is freely movable in the relatively large opening of the bus component 2 and together with the abutting edge at the side wall portions 5a and 5b of the bus component 2. A stopper is formed, and the stopper prevents the movement of the first crossbar 7a from moving away from the bottom portion 4 of the bus component 2 beyond the position shown in the drawing.

Here, an electric conductor can be introduced in the free space between the first crossbar 7a and the bottom portion 4 in the direction from the lower side of the first crossbar 7a to the second crossbar 7b. At this time, the electric conductor is sandwiched at the tightening position of the conductor connecting contact element 1 formed by the tightening end edge of the spring tongue piece 8 and the contact protrusion of the bottom portion 4. In the illustrated embodiment, the contact tongue piece 11 is cut out from the bottom portion 4 of the bus component 2, and the contact tongue piece 11 is directed obliquely upward from the surface of the bottom portion 4 in the direction of the second crossbar 7b. This provides a funnel-shaped conductor introduction region with a pointed angle of tightening position.

The introduced electric conductor causes the spring tongue piece 8 to be turned in the direction of the surfaces of the crossbars 7a and 7b. Since the spring force formed as a result is supported via both support fingers 9 in the respective support openings 10, the tightening spring element 3 exists in a fixed stable position with respect to the bus component 2.

The first crossbar 7a can be pushed downward in the direction of the bottom portion 4 in order to open the tightening position and take out the electric conductor. At this time, the tightening edge of the spring tongue piece 8 is formed by the contact portion 12 at the side edge of the spring tongue piece 8 that abuts on the attached ridge line edge 13a and 13b of the side wall portions 5a and 5b in this opening motion. Is achieved to move away from the bottom portion 4 in the direction of the second crossbar 7b of the tightening spring element 3. This is made possible by the pivot support of the tightening spring element 3 in the bus component 2.

FIG. 2 shows a side view of the conductor connecting contact element 1 from FIG. Here, it can be seen that the contact portion 12 formed as a protrusion portion laterally protruding from the spring tongue piece 8 abuts on the attached ridge line edge 13a, 13b of the side wall portions 5a and 5b. Here, when the tightening spring element 3 is moved relative to the bus component 2 by performing the opening motion by the pressure on the first crossbar 7a in the direction of the bottom portion 4, the first cross The portion of the spring tongue piece 8 connected to the bar 7a also moves in the direction of the bottom portion 4. The abutting portion 12 is fixed in position with respect to the bus component 2 at this position, and is held by the ridge edge edges 13a and 13b of the side wall portions 5a and 5b of the bus component 2. In this case, the height position in the direction perpendicular to the conductor insertion direction L or the position relative to the direction of the opening motion is maintained. In some cases, for example, the swinging motion of the spring tongue piece 8 allows the contact portion 12 to move in the conductor insertion direction L on the edge edges 13a and 13b of the ridgeline within an allowable range. The contact of the spring tongue piece 8 is operated so that the freely movable end portion of the spring tongue piece 8 having the tightening end edge moves in the opposite direction away from the bottom portion 4 of the bus component 2. As a result, the tightening position is opened.

Further, the bus component 2 has a conductor receiving pocket formed by a bent material flap 14 at the rear end, and the conductor receiving pocket is an electric conductor beyond this end of the conductor connecting contact element 1. It can be seen that it prevents the pushing of.

FIG. 3 shows a vertical cross-sectional side view of the conductor connecting contact element 1 from FIG. It can be seen that the contact protrusion in the shape of the contact tongue piece 11 is cut out from the bottom portion 4 and is directed upward from the surface of the bottom portion 4 in the direction of the second crossbar 7b. As a result, a tightening position for sandwiching the electric conductor is provided together with the free end portion of the spring tongue piece 8 forming the tightening end edge 15. The end of the contact tongue piece 11 directed to the tightening edge 15 has a chamfered portion 16 with a surface, and the contact tongue piece 11 is a contact tongue piece 11 in the conductor insertion direction from the region of the first crossbar 7a. It extends to the vicinity of the region of the bottom portion 4 located behind 11. As a result, in the optimum conductor guide, the optimum contact protrusion for sandwiching the electric conductor is formed, and the tightening force of the spring tongue piece 8 is concentrated on the contact protrusion.

Further, it can be seen that the freely movable end portion of the spring tongue piece 8 is further bent in the direction of the bottom portion 4. As a result, the contact end 17 of the spring tongue piece 8 is directed toward the bottom portion 4 at a steeper angle than the other region of the spring tongue piece 8 connected to the first crossbar 7a. This is such that the contact portion 17 lifts from the bottom portion 4 or the contact tongue piece 11 more rapidly than at a smaller angle as a result of the pressure-induced opening motion in the direction of the bottom portion 4 to the first crossbar 7a. To do.

Further, it can be seen that the support finger 9 existing below the second crossbar 7b is float-supported in the relatively small support opening 10. This provides one type of pivot bearing or rotary bearing with a rotating shaft. On the other hand, the support finger 9 existing under the first crossbar 7a can enter the relatively large support opening 10 and can move almost freely. The support finger 9 essentially serves only to provide abutment of the accessory side wall portions 5a and 5b to the abutting surface 18. For this purpose, there are protrusions or fingers located on the side wall portions 5a and 5b, respectively, between the bottom portion 4 and the region of the first crossbar 7a or the spring tongue piece 8 connected to it.

The tightening spring element is also in the absence of the electrical conductor inserted by the abutment 12 abutting on the edge edges 13a, 13b of the ridge and by at least one support finger 9 supported within the attached support opening 10. A fixed position or posture with respect to the bus component 2 of 3 is provided.

Further, it can be seen from at least one side wall portion 5a, 5b that the material flap 14 is bent and laterally inserted into the conductor introduction channel below the second crossbar 7b. As a result, the conductor receiving pocket is formed on the end side.

Further, it can be seen that the bottom portion 4 has an inclined surface 19 on the inlet side, and the inclined surface 19 forms a funnel-shaped conductor introduction region. Corresponding inclined surfaces also exist on the side wall portions 5a and 5b of the bus component 2.

This is also clear from the perspective view from FIG.
FIG. 4 shows a side sectional view of the conductor connecting contact element 1 having the inserted electric conductor 20. In this case, the bare end 21 of the electric conductor 20 is inserted into the conductor introduction channel in the conductor insertion direction L. The conductor connection contact element 1 exists in the open position. In this case, the opening force F is applied to the first crossbar in the direction of the bottom portion 4. At this time, it can be seen that the contact portion 17 at the freely movable end of the spring tongue piece 8 moves away from the contact protrusion at the chamfered portion 16 of the contact tongue piece 11. As a result, the tightening position between the contact end edge 15 and the contact protrusion 16 on the contact tongue piece 11 is opened, and the electric conductor 20 can be pulled out from the conductor connection contact element 1 in the direction opposite to the conductor insertion direction L.

FIG. 5 shows a perspective view of the bus component 2 with respect to the conductor connecting contact element 1 from FIGS. 1 to 4. In this case, it can be seen that the bus component 2 is formed as a single component from the thin plate component. Two side wall portions 5a, 5b facing each other are bent from the bottom portion 4, and the two side wall portions 5a, 5b provide a conductor introduction channel. Here, it can be seen that, for example, a square support opening 10 having rounded corners exists in the rear region of the side wall portions 5a and 5b. A boundary is formed in the cross section of the support opening 10, and the circumference of the support opening 10 is completely closed.

On the other hand, the support opening 10 in the anterior region is not completely closed around and is freely accessible. This allows the tightening spring element 3 to be fitted into the bus component 2. Here, it is important that the stopper is present due to the abutting surface 18 at the protruding protrusions of the side wall portions 5a and 5b. The abutting surface 18 faces the direction of the bottom portion 4.

Further, it can be seen that the material flaps 14 are folded back from both side wall portions 5a and 5b at the rear end to form the conductor receiving pocket. The material flap 14 of the side wall portion 5a faces the opposite side wall portion 5b and the material flap on the opposite side faces in the opposite direction.

Further, it can be seen that the other material flap 22 in the free end region of the contact tongue piece 11 is bent from each of the side wall portions 5a and 5b toward the opposite side wall portions 5b and 5a. The material flap 22 is slightly offset upward from the end of the bottom portion 4 in the direction of the second crossbar 7b and forms a stopper for the contact tongue piece 11. This can be further seen from FIGS. 3 and 4.

FIG. 6 shows a perspective view of the tightening spring element 3. Similarly, the tightening spring element 3 is formed as a thin plate element whose cross section is bent into a U shape. Here, it can be seen that the support fingers 9 are cut out from the side walls 6a and 6b, respectively, and are directed in the directions of the side walls 6a and 6b on the opposite sides.

Further, it can be seen that the spring tongue piece 8 is connected to the first crossbar 7a and extends downward between the side walls 6a and 6b in the free space between the first crossbar 7a and the second crossbar 7b. In this case, the spring tongue piece 8 is bent downward into the channel from the surface formed by the first and second crossbars 7a, 7b.

Further, it can be seen that the contact portion 12 is formed on the spring tongue piece 8 by the protrusions protruding on both sides.
