Definitions

  • At least one clamping slide having an opening is arranged displaceably transverse to the direction of introduction of the conductor into the recess.
  • a spring cooperates with the clamping slide and strives to force such clamping slide into a position wherein the opening thereof is transversely displaced with regard to the cross-section of the recess, thus reducing the free width of said recess.
  • the clamping slide comprises a plate member disposed at least approximately perpendicular to the conductor-introduction direction for said recess, with the contact element extending through the opening of such clamping slide-plate member. At least one edge of the opening of the clamping slide-plate member which extends parallel to the direction of displacement of such clamping slide-plate member is displaceably guided in a transverse groove of the contact element.
  • the present invention relates to a new and improved construction of screwless electrical quick-connection terminal or terminal block with at least one recess for introducing at least one electrical conductor.
  • connection terminals or terminal blocks there are arranged in known manner within an insulated housing a contact element which at least partically delimits or bounds the aforementioned recess, at least one clamping slide having an opening and displaceable transverse to the conductor infeed or introduction direction for the recess, and a spring member which cooperates with such clamping slide.
  • This spring member strives to force the clamping slide into a position where its opening is transversely displaced with respect to the cross-section of the recess and thus the free width of the recess is reduced in size.
  • connection terminal or terminal block of this type permits displacing the clamping slide against the action of the spring member in such a fashion that its opening comes into alignment with the cross-section of the recess. Then, one or a number of electrical conductors can be introduced into the opening of the clamping slide. Thereafter by releasing the clamping slide the thus introduced conductor can be pressed against the contact element by means of the clamping slide owing to the action of the spring member. As a result, the conductor is fixedly retained in the connection terminal and there is established an electrical contact between the conductor and the contact element.
  • connection terminal The advantages which can be realized with this type of connection terminal reside in the fact that the connection and release of the conductor can be undertaken quickly, without any great effort, and clamping of the conductor, realized by the action of the spring, cannot be unintentionally released, for instance due to jarring.
  • a further significant object of the present invention relates to a connection terminal which is relatively simple and inexpensive to manufacture.
  • the invention contemplates constructing the clamping slide in the form of a plate member arranged at least approximately perpendicular to the direction of introduction of the conductors into the recess, hereinafter sometimes simply referred to as the introduction direction of the recess.”
  • the contact element piercingly extends through the opening of the clamping slide-plate member, and at least one edge of the opening of the clamping slide-plate member, which edge extends parallel to the direction of displacement of such clamping slideplate member, is displaceably guided in a transverse groove of the contact element.
  • Two oppositely sit'uated parallely extending edges of the opening of the clamping slide-plate member can be advantageously displaceably guided in two oppositely disposed transverse grooves of the contact element.
  • the contact element can be advantageously provided with a groove or notch which in cross-section possesses a substantially V-shaped configuration, the
  • connection terminal or terminal block renders possible the selective positive clamping of a number of electrical conductors of the same or different diameter, also only a single conductor having a relatively small diameter.
  • a particularly good clamping action and electrical contact can be realized if at least two similar clamping slide-plate members are arranged adjacent one another in parallelism and are displaceably guided in the same or in separate transverse grooves of the contact element. Furthermore, the parallel juxtapositioned clamping slideplate members can be subjected to the action of a common resilient or spring member.
  • connection terminal can possess two aligned recesses, each of which serves for the introduction of at least one electrical conductor.
  • at least one clamping slide-plate member For each of the aforementioned recesses there is provided at least one clamping slide-plate member and such clamping slideplate members can be displaceably guided in separate transverse grooves of a common contact element. It is thus possible to associate with all of the clamping slideplate members a common flexible spring or resilient element, for instance a wound leg spring or spiral spring or a blade spring.
  • FIG. 1 is a schematic longitudinal sectional view through a preferred constructional form of screwless electrical quick-connection terminal or terminal block with two aligned recesses, each of which serves for the introduction of at least one electrical conductor;
  • FIG. 2 is a front view of the connection terminal depcted in FIG. 1 as viewed from the left side thereof;

  • connection terminal or terminal block depicted in FIGS. 1 and 2 will be seento embody a substantially flat insulated housing 10 which is provided at two opposite flat faces of such housing, namely to the left and right of the illustration of FIG. 1, with a respective recess 11 for introducing at least one electrical conductor, such as the conductors 12, 13 and 14 specifically depicted in FIGS. 1 and 3. Both of the recesses 11 are arranged at the insulated housing 10 so as to be in substantial alignment with one another.
  • a contact element 15 formed of metal and having the shape of a profiled rod is located internally of the housing 10 and extends by means of both of its end portions 15a into each neighboring aligned recess 11.
  • Contact element 15 possesses a continuous lengthwise extending groove or channel 16 having a substantially V-shaped cross-sectional configuration, as best seen by referring to FIGS. 2 and 3.
  • the lengthwise direction of this V-shaped groove 16 extends parallel to the conductor infeed or introduction direction for the recess 11, and both of the V-flanks 16a of such V- shaped groove 16 form a respecitve partial boundary or delimiting wall for the associated space of the corresponding recess 11 serving to receive the conductors 12, 13 and 14.
  • each end portion 15a of the contact element 15 is provided with two opposed lateral transverse grooves or groove means 17 serving to guide clamping slide-plate members 18 arranged substantially perpendicular to the lengthwise direction of the contact element 15 and to the conductor-introduction direction for the recesses 11.
  • the clamping slide-plate members 18 each possess a respective opening or window 19 through which piercingly extends the contact element 15. More specifically, it will be also observed that two oppositely situated parallely extending marginal edges 20 of the opening 19 for each clamping slide-plate member engage in the oppositely directed or opposed transverse grooves 17 of the contact element 15, as particularly well illustrated in FIGS. 3 and 5.
  • each clamping slide-plate member 18 is displaceably guided in the lengthwise direction of the edges 20 of the openings 19, the direction of displacement coinciding with the depth direction of the V-shaped groove 16 of the contact element 15.
  • Each two immediately parallel juxtapositioned clamping slide-plate members 18 engage with the same transverse grooves l7, as shown in FIGS. 1, 4 and 5.
  • the opening or window 19 of each clamping slide-plate member 18 possesses two marginal edge portions 21 arranged inclined towards one another in a substantially V-shaped configuration and which are inclined opposite to the inclination of the V-flanks 16a of the V-shaped lengthwise extending groove 16 of the contact element 15.
  • FIG. 1 illustrates the manner in which the central portion of the spring 23 possesses one or a number of windings or coils 24 surrounding a pin-shaped portion 25 of the housing 10.
  • the end portions of the spring 23 form approximately linearly extending legs 23a which strive to upwardly pivot in the showing of FIG.
  • the flexible spring 23 and the clamping slide-plate members 18 are housed in suitable hollow spaces or compartments 26, 27 and 28 of the insulated housing 10.
  • the upper ends of the clamping slide-plate members 18 as seen in FIG. 1 are accessible from the outside through the hollow spaces or compartments 28 by means of a rod-shaped auxiliary device or tool 29, for instance a screw driver, in order that the clamping slide-plate members 18 can be displaced against the action of the spring 23 during such time as electrical conductors 12, 13, 14 or the like are to be introduced into the connection terminal or released therefrom.
  • the hollow spaces or compartments 26 and 27 as well as the non-visible hollow space which contains the contact element 15 can be open towards the one flat side of the housing 10 in order to render possible installation of the components 15, 18 and 23.
  • cover plate 30 (FIG. 2) which closes-off the hollow compartments and covers the internal components 15, 18 and 23 of the connection terminal.
  • cover-plate 30 it is equally possible to omit the use of a cover-plate 30, especially in those cases where two or more of the described connection terminals or terminal blocks are intended to be arranged in direct side-byside arrangement in a row in known manner.
  • the housing-10 is equipped with resilient elastic legs 31 which enable clamping the connection terminal or terminal block with a suitable conventional profile rail or mounting bar. Furthermore, a number of grooves 32 having undercut flank portions are likewise formed in conventional manner at the outside of the housing 10 and which serve for selectively receiving indicating tags or marking shields 33 or the like.
  • connection terminal there will be next considered the use and mode of operation thereof which is as follows:
  • the rod-shaped tool 29, i.e., the screw driver for instance is placed into the open mouth of the relevant hollow compartment 28 and the two immediately adjacently arranged clamping slide-plate members 18 are pressed deeper into the housing against the action of the spring 23, in other words downwardly in the showing of FIG. 1.
  • the clamping slideplate members 18 are displaced with regard to the contact element 15 in such a manner that the V-shaped arranged edge portions 21 of the openings 19 move away from the flanks 16a of the V-shaped groove or channel,
  • the opposed V-like arrangement of the flanks 16a of the groove 16 and the edge portions 21 of the openings 19 of the clamping slide-plate members 18 has the advantage that two or three electrical conductors of the same or different diameter can be clamped practically as good and positively as a single conductor of large or also small diameter.
  • FIG. 3 there is illustrated, for instance, the situation where three conductors 12, 13 and 14 are clamped.
  • FIG. 2 illustrates that it is still possible to fixedly clamp a single conductor of small diameter.
  • connection terminal The introduction of one or a number of conductors into the other recess 1 1 of the connection terminal can take place similar to the above-described procedures.
  • Each leg of the spiral spring 23 is elastically flexible independently of the other leg, so that both recesses 11 of the connection terminal can be also manipulated individually and independently of one another.
  • connection terminal depicted in FIG. 6 differs from the above-described construction, firstly in that instead of using a spiral spring 23 with a wound central portion 24 there is provided a blade spring 23' supported by its central portion upon a pin-shaped carrier or support element 25 of the housing.
  • a further difference resides in the fact that the clamping slide-plate members 18 which, in each instance form a pair, are guided in separate transverse grooves of the contact element 15, so that the clamping slide-plate members 18 possess a certain spacing from one another.
  • the remaining construction of this embodiment of connection terminal can be the same as that considered for the first embodiment discussed above in connection with FIGS. 1 to 5.
  • connection terminal in contrast to the'conventional screwless connection terminals, possess the advantage that the clamping slides 18 constructed as plate members produce a better electrical contact with the clamped conductors and the clamped conductor or conductors are also secured much better against being pulled out of the connection terminal than was possible when employing the previously known constructions of clamping slides.
  • the aforementioned advantage is realized by the features that the clamping marginal or edge portions 21 of the openings 19 of the relatively thin clamping slide-plate members 18 tend to conform much better to the momentary shape of the conductor and to come into much snugger contact therewith and also tend to somewhat penetrate into the material of the conductor so that larger contact surfaces prevail.
  • connection terminals or terminal blocks also especially tend to distinguish themselves by virtue of their relatively simple construction and their simplicity in fabrication and assembly.
