In order to produce an easy to use spring clamp, the invention provides for the clamping body (2) to be held in a pretensioned position before inserting the conductor (3) into the connecting area (1) and for the clamping body (2) to be released after the conductor (3) has been inserted into the connecting area.
Description
Technical field
The present invention relates to a kind of spring clip, it has a clamp that is located in the Wiring area, this clamp before the electric wire with a wire axis is introduced into Wiring area by clamping on a clamped position, and can be released after electric wire is introduced into Wiring area, introduce electric wire in the Wiring area thus can be on a clamped position under the spring force effect by clamping.
Background technology
A kind of like this spring clip is for example open by DE 1,213 024 B2.
In existing spring clip,, lead unclamps clamp by being introduced in the Wiring area or by the external force manual operation.Under first kind of situation, spring clip can only be used for solid conductor, and can not be used for flexible wire, especially twisted wire.Under second kind of situation, can not carry out one-handed performance.
Summary of the invention
The objective of the invention is to improve spring clip, under the flexible wire situation, also can carry out one-handed performance even if make it.
Purpose of the present invention realizes thus, that is, and and axially pulling out motion and can unclamp clamp by lead.
Spring clip of the present invention has a clamp that is located in the Wiring area, this clamp before the lead with a wire axis is introduced into Wiring area by a holding element clamping on a pre-clamped position, and can be released after lead is introduced into Wiring area, introduce lead in the Wiring area thus can be on a clamped position under the spring force effect by clamping, described spring clip comprises a releasing member relevant with described holding element, and described clamp can be released by the interaction between releasing member and the lead when axially pulling out of lead moved.
One of spring clip of the present invention improves design and is,
-described holding element has two and is arranged in the clamp and the clamp arm in an articulated joint of being hinged, so that clamp is remained on pre-tension position, these two clamp arms are maintained at and exceed the dead-centre position part slightly,
-after lead was introduced Wiring area, described clamp arm can shift out through the dead-centre position,
-in the process of axial drawing lead, described lead acts on the clamp arm by a releasing member.
Another technical scheme is that described holding element is a releasable brake mechanism, so that clamping body is locked on the pre-tension position, this lead axially can acted on the brake mechanism by a releasing member in the drawing process.
Described brake mechanism preferably bears spring-loaded.
When described releasing member its towards lead point has clamp at the end time, when axial drawing lead, described releasing member can tightly vise lead.
When clamp has one when being used to cut the cutting edge of the presumable insulated hull of lead, just having saved needed to remove its insulated hull before lead is introduced spring clip.
Description of drawings
By the accompanying drawing illustrated embodiment other advantage of the present invention and details are described in detail below, in the accompanying drawing:
Fig. 1 illustrates a spring clip;
Fig. 2 illustrates a clamp that is in pre-tension position;
Fig. 3 illustrates the clamp when unclamping;
Fig. 4 illustrates the clamp that is in clamped position;
Fig. 5 illustrates another spring clip.
Embodiment
According to Fig. 1, a spring clip has a Wiring area 1.In this Wiring area 1, be provided with a clamp 2.The electric wire with a wire axis 43 that stretches in the Wiring area 1 by 2, one of this clamps can be clamped under the spring force effect on the clamped position.
Be provided with two clamp arms 5 in clamp 2, they are by an articulated joint 5 ' interconnect.These two clamp arms 5 can exceed the dead-centre position a bit slightly through moving.Between two clamp arms 5, can constitute (ueberstumpfen) the open-angle α of reflex angle slightly like this.This open-angle α is between 180 ° and maximum 190 °.This open-angle α is owing to the structure of two clamp arms 5 is limited on this numerical value.By with clamp arm 5 opening angle α, before opening clamp 2 and holding it in a lead-in conductor 3 on the determined pre-tension positions.Open clamp 2 by a unshowned operating mechanism.This operating mechanism for example can be a screwdriver, and it is by acting on clamp arm 5 in the gap in (being inserted in) spring clip and the clamping body 2.
Operation principle below in conjunction with Fig. 2-4 pair spring clip shown in Figure 1 is described in detail.
When X vertically introduces Wiring areas 1 with lead 3, releasing member 6 and its end point 7 X motion equally vertically.As long as lead 3 moves along incoming direction X, clamp 2 just can not unclamp.
Releasing member 6 has clamp 8 at its end point 7.When attempting contrary its incoming direction X of lead 3 are pulled out in Wiring area 1 again, this clamp 8 can vise electric wire 3 or its insulated hull 3 '.Described releasing member 6 is bearing on the pin joint 9.This pin joint 9 articulated joint 5 ' near.Under best situation, the same pin joint of this pin joint 9 and articulated joint 5 ' be completely integrated into.
Releasing member 6 effectively is connected with clamp arm 5.After lead 3 is introduced Wiring areas 1, by back spur lead 3 and thereupon clamp 8 vise lead 3 or its insulated hull 3 ', clamp arm 5 at first moves to the dead-centre position from its resting position.This state is illustrated by Fig. 3.
With lead 3 further when Wiring area 1 is pulled out, clamp arm 5 shifts out from the dead-centre position.Clamp 2 is released thus.By the axial motion of lead 3, clamp 2 is released or unclamps and its clamped position that rebounds thus.
Clamp its clamped position that rebounds is finished under the spring force effect.This spring force can be used to simultaneously to cut the insulated hull 3 that lead 3 may exist '.Clamp 2 has a cutting edge 10 for this reason.
Above-mentioned spring clip can have many different modification.Lead 3 for example can act directly on the clamp arm 5.In this case, when introducing lead 3 in the Wiring area 1, just begin to unclamp clamp 2.In addition, the releasing member 6 that has an end point 7 can be pressed on the backstop under pre-tensioning state.A kind of like this structure makes the mechanical load of articulated joint 5 ' bear become minimum.In contrast, the advantage that has of diagram form of implementation is, above-mentioned spring clip can need not external force and discharge and just can unclamp, thereby manipulated with one hand especially, and suitable too to flexible wire.
Figure 5 illustrates another form of implementation of spring clip of the present invention.In this form of implementation, clamp 2 has a draw-in groove 11, and clamp 2 is by it and brake mechanism 12 releasable by, that bear load on spring can be by locking in addition.After lead 3 is introduced Wiring area 1, at first be that the releasing member 6 of spring clip moves along incoming direction X equally.Attempting lead 3 when Wiring area 1 is pulled out, releasing member vises lead 3.Thus brake mechanism 12 is extracted out from draw-in groove 11, clamp 2 just is transformed into clamped position from pre-tension position suddenly like this, and then lead 3 is clamped.In addition, the function of spring clip shown in Figure 5 is the same with the function of spring clip shown in Fig. 1-4.Therefore components identical also has identical Reference numeral.
