Description
Technical field
The present invention relates to a kind of elastic wire folder.
Background technology
Electrical wire clip or binding post, for the formation of electrical contact or electrical connection, namely form a kind of conduction and connect between an osculating element and a subtend contact element.The application of electrical wire clip is very extensive, and electrical wire clip all can be used in the field needing terminal to connect in elevator, electric power, traffic, automation etc.
Be in the patent of DE19817927C1 in the patent No., disclose a kind of electrical wire clip, this electrical wire clip comprises a terminal spring substantially taken the shape of the letter U and a L-shaped metalwork, L shape metalwork have one with the vertically disposed rectangular aperture of conductor direction of insertion, conductor to be connected can insert described opening.U-shaped terminal spring is arranged in said opening with the end of side leg, make before terminal spring spring circular arc is backward positioned at described opening along conductor direction, and the conductor that has been inserted is pressed on the edge of described opening by the clamping leg of terminal spring, thus terminal spring and metalwork form a spring force clamping connection mechanism.
A shortcoming of above-mentioned patent is: needing to use extra operation tool to open terminal spring could be inserted between terminal spring and metalwork by conductor, but when utilizing operation tool to open terminal spring, terminal spring may be caused to slide, even make the end of the side leg of terminal spring skid off from described opening, like this when inserting conductor, just can not guarantee reliably to contact between conductor with metalwork.
Be in the patent of US7083463B2 in the patent No., disclose a kind of electrical wire clip, this electrical wire clip comprises a terminal spring and a metalwork, terminal spring has a clamping leg and contacts leg with one, metalwork has a conduction rod member (conductorbarpiece), the conductor clamping that elastic force between clamping leg and conduction rod member will insert wherein, the contact leg of terminal spring has a through hole for inserting wire, and the one end simultaneously clamping leg extends through through hole.Clamping leg has a maintaining part, the bearing of trend of maintaining part is substantially parallel with the direction of insertion of wire, simultaneously parallel with the direction of conduction rod member, conduction rod member inserts through hole along the direction contrary with wire direction of insertion, thus conduction rod member is stably clipped between clamping leg and maintaining part.
In above-mentioned patent, the hardness of terminal spring is higher, and when wire being inserted clamping leg with conduction rod member, also need first with other TO clamping leg, and then inserted by wire, this makes electrical wire clip there is inconvenience in use.In addition the moulding process of this terminal end is more complicated.
Summary of the invention
Main purpose of the present invention is to provide a kind of elastic wire to press from both sides, and electrical wire clip directly between inserted terminals spring and metalwork, can be opened without the need to using extra instrument by single cord or stranded conductor or the thin stranded conductor being added with cold junction head.
Another object of the present invention is to provide a kind of elastic wire to press from both sides, the clamping leg surface of the terminal spring of this elastic wire folder forms a reinforcement, when wire inserts between clamping leg and metalwork, reinforcement can play the effect of guiding, thus offsets when avoiding wire to insert; In addition, the contact of clamping leg and wire becomes Multi-contact or linear contact lay from traditional single-contact, improves the stability of clamping wires; When the conductor size inserted is identical, the deformation that the clamping leg being provided with reinforcement occurs is little compared with the clamping leg not having reinforcement, therefore improves the useful life of terminal spring and the reliability of electrical wire clip.
Another object of the present invention is to provide a kind of terminal spring for electrical wire clip, the similar G shape of shape of this terminal spring, when this terminal spring is used for electrical wire clip, single cord or stranded conductor or be added with the thin stranded conductor of cold junction head can directly between inserted terminals spring and metalwork, and without the need to using extra instrument to be opened by electrical wire clip.
Another object of the present invention is to provide a kind of terminal spring for electrical wire clip, the clamping leg surface of this terminal spring forms a reinforcement, reinforcement can play the effect guiding wire, improves stability during terminal spring clamping wire, and is conducive to the useful life of improving terminal spring.
For reaching above object, the invention provides a kind of elastic wire folder, comprise G shape terminal spring, metalwork and insulation crust, described terminal spring and described metalwork are located in described insulation crust, described insulation crust has wiring inlet, described metalwork has rail-engaging part, described terminal spring has a clamping leg, one supporting leg and one keeps leg, described clamping leg is connected with described maintenance leg by described supporting leg, described maintenance leg upwards extends from the side of described supporting leg, described clamping leg inclination extends downwardly towards the upper end of described maintenance leg, described supporting leg has a through hole, described rail-engaging part is suitable for inserting described clamping leg and described maintenance leg from the below of described supporting leg through described through hole, thus described terminal spring is sandwiched in described rail-engaging part by the elastic force between described clamping leg and described maintenance leg.
When wire inserts from described wiring inlet, under the guiding of described wiring inlet, described wire is inserted between described clamping leg and described rail-engaging part, thus utilize described clamping leg to be out of shape the elastic force produced, described wire is tightly clipped between described clamping leg and described rail-engaging part.For traditional electrical wire clip, the clamping leg of terminal spring normally contacts with rail-engaging part through the through hole of supporting leg, and at this moment because the clamping leg of terminal spring and the contact point of described rail-engaging part are away from wiring inlet, therefore the length of wire insertion end is longer.And in the present invention, the clamping leg of described terminal spring and the contact point of described rail-engaging part are away from described supporting leg, described contact point is closer to described wiring inlet, therefore the length of described wire insertion end is correspondingly less, thus not easily there is deformation when inserting in wire, if the wire therefore inserted be single cord or stranded conductor or the thin stranded conductor being added with cold junction head time, directly can not be inserted in described electrical wire clip by extra instrument.
In addition, the terminal spring of G shape is compared with the terminal spring of U-shaped, more convenient with the connected mode of metalwork, G shape terminal spring does not need to be connected with metalwork by terminal spring by riveted joint, only utilize the elastic force between described clamping leg and described maintenance leg, described terminal spring reliably can be connected with described metalwork.In addition, G shape terminal spring is compared with the terminal spring of other shapes, and its procedure of processing is simple, and production efficiency is high.
