Description
Technical field
The present invention relates to a kind of elastic clamping contact, the spring that this elastic clamping contact has bus bar elements and formed by the flexural spring plate, described this flexural spring plate has contact arm, spring bending section and clamping limb, and clamping limb is orientated in order to form clip position in the direction of bus bar elements.
The invention still further relates to a kind of terminal component, the conductor patchhole that it has insulating material housing and is arranged in insulating material housing, described conductor patchhole leads to each join domain.
This class elastic clamping contact is used for terminal component with various forms, is used for electric conductor is connected to terminal component.In the case, the conductor that the on-insulated end of these electric conductors is inserted in the terminal component inserts in the hole, and presses bus bar elements by the elastic clip gripping arm, is electrically connected in order to set up between conductor and bus bar elements.
Background technology
As example, DE19654611B4 has described a kind of this elastic clamping jockey of describing in preface part, leaf spring forms the form of the ring with U-shaped opening in the case, and have backward spring bending section and with two spring arms of described spring bending section adjacency.For example, the elastic clamping contact of cage shape extension spring form also can be known from DE19741163C2 and DE19711051A1.
Requirement provides enough spring chucking powers and causes comprising the bending radius existing problems that the terminal component of this elastic clamping contact broadens.
In order to reduce the overall width of terminal component on the spring direct of travel of clamp springs, has quite large diameter leaf spring with respect to bending to U-shaped and spring bending section, DE102007033097A1 has proposed farthest to reduce the spacing between the each several part of spring bending section parallel to each other, and the radius of spring bending section thus.In the case, can obtain elastic force from clamping limb and contact arm.
Summary of the invention
By the above, the object of the present invention is to provide a kind of further improved elastic clamping contact, this elastic clamping contact provides large chucking power with as far as possible little overall width.
Dependence has along the spring bending section of the material groove of the longitudinal extension of latch plate, realizes this purpose by the elastic clamping contact that preface part is mentioned.
So, the present invention suggestion on the longitudinal direction of latch plate in spring bending section setting example as being material groove slit or form of grooves and that not exclusively run through latch plate.These material grooves that formed by the material displacement for example cause the elastic force on the latch plate longitudinal direction to enlarge markedly.The elastic force effect that has been found that bending radius can enlarge markedly by the material groove.Reason is, it or not single spring element in bending radius, but set up a plurality of springs zone, this a plurality of springs zone be arranged to so that they by the material groove spaced and horizontal movement, the elastic force in described spring zone acts as that index increases and greater than the elastic force effect of the spring bending section that does not have the material groove.When spring bending, spring material flows into the material groove, and the effective width of spring increases thus, and the radius of spring bending section reduces width and increases, and a kind of energy storing device that do not change is provided.
When the material groove during from spring bending section surface convergent, can produce special benefit along the center position of the sweep that is limited by spring bending section on external diameter.That is to say that the slit in the spring bending section or groove are with roughly circular cone mode ecto-entad extension.Spring force can further increase thus.
When a plurality of material grooves (2,3,4,5 or more) transverse to the parallel longitudinal setting of latch plate and when spaced, can produce special benefit.Spring bending section is divided into a plurality of springs zone, and this a plurality of springs zone is spaced by the material groove, and is parallel to their acting force of the spring action.
This purpose can also realize that with the terminal component that is arranged in the conductor patchhole of this insulating material housing described conductor patchhole leads to join domain separately by having insulating material housing, and above-mentioned elastic clamping contact is incorporated in this join domain.
Description of drawings
Below with reference to accompanying drawings, the present invention is described more at large, wherein:
Fig. 1 shows the cross-sectional view that combines the terminal component behind the elastic clamping contact.
Fig. 2 shows the plane graph of the spring bending section of elastic clamping contact.
Fig. 3 shows the sectional view of the first embodiment of the spring bending section with slit.
Fig. 4 shows the sectional view of the second embodiment of the reeded spring bending of tool section.
Embodiment
The details of terminal component 1 in the sectional view that Fig. 1 shows from the side.Terminal component 1 can be terminal band for example.Spring 3 is incorporated in the insulating material housing 2 of terminal component 1, described spring have a contact arm 5 by bus bar elements 4, with the spring bending section 6 of described contact arm adjacency and with spring bending section 6 adjacency and the clamping limb 7 relative with contact arm 5 positions.
The free end of clamping limb 7 forms the clip position of that end of the electric conductor of peelling off insulation with bus bar elements 4, and described electric conductor can be inserted in the conductor patchhole 8 in the insulating material housing 2 thus.In the case, clamping limb 7, shown in dotted line, crooked along the direction of contact arm 5, in order to open clip position.Clamping limb 7 also can be crooked by means of operation tool, and described operation tool is inserted in the handle hole 9 adjacent with conductor patchhole 8.Be applied to the spring performance that chucking power on the electric conductor depends on spring 3 basically by clamping limb 7, and the design of also depending in the case spring bending section 6.
Keep simultaneously large as far as possible elastic force in order spring bending section 6 to be designed to have as far as possible little radius, save thus the space, spring bending section 6 has the material groove, and this material groove is vertical latch plate, namely in 7 the direction from contact arm 5 to clamping limb, extend.
Fig. 2 shows the plane graph of the spring 3 in spring bending section 6 zones.Can find out that material groove 10 vertically extends to clamping limb 7 from contact arm 5 along latch plate.In the case, a plurality of slit or the groove material groove 10 that be arranged in parallel into adjacent one another are.
Fig. 3 shows the cross-sectional view at the latch plate of the regional inner spring 3 of spring bending section 6.Can find out that material groove 10 is set to the mode of slit, adjacent one another are being arranged in parallel, and run through latch plate fully.In example shown embodiment, groove design is to extend with the inner surface of convergent mode from the upper surface of the latch plate of the outer radius of spring bending section to the inner radius of spring bending section 6.
Fig. 4 shows another embodiment of spring 3, and this spring 3 has the material groove 10 of form of grooves, and these grooves are adjacent one another are to be arranged in parallel, and does not run through latch plate fully.These grooves or chase can extend to bottom portion of groove in the convergent mode equally.
These slits or groove can have constant slot width or recess width when producing.Described slit and groove deform subsequently so that after the regional bending of spring 3 in spring bending section 6, they taper to internal diameter by external diameter.
