Definitions
- the invention relates to a tension spring clamp with two tension springs arranged mirror-symmetrically to one another in a housing.
- These tension springs each have a contact leg seated on a current bar and a spring leg with a clamping window that is integral therewith and loop-shaped together with the contact leg.
- the contact leg of the tension spring in question protrudes with its end and the current bar through the clamping window of this spring leg.
- the two spring legs of the tension springs are arranged facing each other, and they can be pressurized by means of an actuating element arranged in the housing of the tension spring me, into which a tool blade can be brought into engagement, for compression in the direction of the contact leg while opening the clamping window.
- Said actuating element is located between the two opposing spring legs of the tension springs, it is in contact with both spring legs at the same time and accordingly has contact points for the spring legs of both tension springs on opposite outer sides.
- the actuating element is designed as an oval, rotatable body, which accordingly xi alen diameter and a minimum diameter.
- the maximum diameter is in the plane of symmetry of the tension springs
- their spring legs are not acted upon.
- a rotated position rotated by 90 ° in which the maximum diameter of the actuating element is perpendicular to the plane of symmetry of the tension springs
- their spring legs are pressurized and springed accordingly towards the respective contact leg of the tension spring, whereby the clamping windows of both tension springs are opened.
- the actuating element has an insertion slot for a screwdriver blade in order to be able to twist it. This is not just about the rotation of the actuating element in the rotational position to act on the spring legs of the tension springs, from this rotational position, the actuating element must also be reset by means of a screwdriver pawl.
- a tension spring clamp in another design is known from document DE 42 39 480 AI.
- actuation pushers which have depressions in which a screwdriver blade can be inserted.
- These actuating pushbuttons are designed as levers with arms of different lengths, the lever depression being located on one lever arm and the other lever arm being provided to act on the spring leg of the associated tension spring.
- the clamping points can only be operated one after the other, even the tool between the actuating pushers must be implemented here.
- Tension spring terminals of the aforementioned type are used in particular as component connectors. Each of the two tension springs of the terminal receives one of the two connecting wires of a wired component.
- the object of the invention is to create a tension spring terminal with which, above all, the wiring such wired components can be made even more easily and in a time-saving manner and in which the actuating element is automatically reset when the actuating tool is removed.
- a tension spring clamp of the type mentioned at the outset in that the actuating element is designed as an elastic or partially elastic expansion body which can be expanded with its outer sides in the direction of the spring legs of the tension spring by inserting the tool blade.
- the actuating element is designed as an expansion body which can be stretched by inserting a conventional wedge-shaped screwdriver blade and, as a result of this, causes pressure to be exerted on the two adjacent spring legs of the two tension spring clamps. Without a multiple rotary or sliding movement, the two clamping points in the area of the clamping window of the two tension springs are thus opened and closed at the same time, with which a wired component on the tension spring terminal as a component connector with both connecting wires can be clamped onto or disconnected from the two tension springs , The elastic actuating element automatically resets when the tool blade is removed and releases the spring legs of the tension springs again. A secure clamping of the wired component is achieved because one It is not possible to open the tension springs when the operating tool is removed.
- Fig. 1 is a cut side view of a tension spring clamp
- FIG. 2 shows a perspective view of the tension spring clamp according to FIG. 1.
- a terminal housing 1 on the underside of which a plug element 2 is formed in order to be able to use the tension spring terminal as a component plug.
- tension springs 3 there are two tension springs 3 in the interior of the terminal housing 1, which are arranged in mirror image to one another.
- Each of these two tension springs 3 has a contact leg 4, which is seated on a current bar 5.
- a spring leg 6 which is bent together with the contact leg 4 in the manner of a loop.
- the spring leg 6 has a clamping leg 7 which is bent back toward the contact leg 4 and which is broken through by a clamping window 8. Chen is.
- the end of the contact leg 4 and the current bar 5 protrude through this clamping window 8.
- the two tension springs 3 serve to contact a component 10 which is wired and on which two connecting wires 11 are led out accordingly. These wires 11 are each clamped at one of the two clamping points in the area of the clamping window 8 of the tension springs 3 by being clamped through the respective clamping window 8 and protruding from the spring leg 6 of the tension spring 3 against the side of the current bar 5 remote from the contact leg 4.
- the mutually facing spring legs 6 of the tension springs 3 must be pressurized, whereby the spring legs 6 deflect in the direction of the contact legs 4 and accordingly the clamping windows 8 in the clamping legs 7 the tension springs 3 are opened.
- This actuation of the tension springs 3, namely the application of their mutually facing spring legs 6, is carried out simultaneously, and an actuating element 12 is used for this purpose, which is arranged between the two spring legs 6 of the tension springs 3.
- the actuating element 12, which is elongated and symmetrical in the direction of the plane of symmetry of the two tension springs 3, has an insertion slot 13 into which a tool blade 14 flattened on both sides, such as that of a screwdriver, can be inserted. Since the actuating element 12 consists of an elastic see material is and can be expanded accordingly, the actuating element 12 can be stretched by means of the tool blade 14 so that a pressure is exerted on the spring legs 6 of the tension springs 3 to open the clamping points.
- the actuating element 12 In order to expand the actuating element 12, in particular the longitudinal walls 19 of the actuating element 12, which delimit the insertion slot 13 and form the outside 17, are elastically extensible. On the line of the actuating element 12, the wedge action of the tool blade can be used. If this is not sufficient, the actuation element 12 can be made by rotating the tool blade 14 seated in the insertion slot 13, because this causes the tool blade 14 to be positioned transversely relative to the insertion slot 13. With the removal of the blade 14, the elastic actuating element is automatically reset and releases the spring legs 6.
- the longitudinal outer sides 17 of the actuating element 12 can form not only punctual contact points but contact surfaces for the spring legs 6 of the tension springs 3 and can be adapted to the outer contour of the tension springs 6 by - as shown in the exemplary embodiment - they have the shape of a shallow indentation, which in a rounded lower edge 18 merges. Characterized are on the actuators 12 sharp, with the outside of the Spring legs 6 of the tension springs 3 wedging edges avoided.
- Figure 2 makes it clear that the tool blade 14 from one of the wide, parallel sides of the. Terminal housing 1 can be used and can even protrude through the terminal housing 1.
- the relevant wall 15 of the terminal housing 1 has a push-through opening 16 through which the tool blade 14 can be inserted into the actuating element 12 located behind it.
- the wired component 10 is inserted with its connecting wires 11 from the open top of the terminal housing 1 remote from the plug element 2. Handling is particularly practical because the inserted tool blade 14 and the connecting wires 11 of the component 10 that are to be inserted or detached do not impede one another.
