Technical field
The utility model relates to a kind of elastic connection terminal of shock-resistant electric current.
Background technology
In multiple fields of electrical wiring technology, relate to elastic connection terminal, it is favourable that elastic connection terminal is installed for equipment, because they can be realized without instrument and installing fast in all cases.For example, at the terminal shown in German patent DE 299 20 231 U1.
For this terminal, the wire of introducing is fixed by flexible member and projection.Wherein, first this flexible member and projection are used for preventing extracting of conductor.Figure 1 illustrates this layout.
But described this layout is not suitable for impulse current, because the contact zone forming between conductor and connecting part in this layout there will be multiple situation, these contact zones electric current that can not withstand shocks.This layout protrusions is from as the first contact zone, inserted when enough dark and just formed the second contact area at conductor, and its second contact area is the part of the front end in contact connecting part of conductor.In the time that hard conductor or the conductor with wiring sleeve insert especially like this.Therefore, existing elastic connection terminal is not suitable for using in overvoltage protection.Such two contact zone situations often can cause occurring welding between conductor and connecting part in the time there is overpressure situation or high current loading, therefore cause conductor not remove from elastic connection terminal without problems again.Especially in the situation that conductors cross is less, attempt to dismantle the fracture that may cause conductor.
In addition, elastic connection terminal of today can only be used for holding different conductor shapes restrictedly.Therefore, the conductor that some elastic connection terminal is only suitable for holding hard conductor and/or has wiring sleeve, and other elastic connection terminal is only suitable for holding flexible conductor.In addition, for all elastic connection terminals, commonly, only have relatively little transversal region to be hidden by elastic connection terminal.Its consequence is, what must spend cost carrys out the many different elastic connection terminals of Design and manufacture.
Summary of the invention
The purpose of this utility model solves the problems referred to above by the elastic connection terminal of shock-resistant electric current, and concrete technical scheme is:
A kind of elastic connection terminal 1 of shock-resistant electric current, be used for without instrument conductor L is installed, comprising: a housing G with conductor L introduction hole; A connecting part A for conducting electricity, and an elastic device F, described elastic device does not stop conductor L to insert binding post 1, and the conductor L inserting in the rear extruding of conductor L insertion binding post 1 contacts with connecting part; Wherein, described connecting part A has multiple protruding E, and in the time having inserted conductor L, described multiple projections are connected with conductor L conduction by elastic device F.
Further: described elastic device F is leg formula spring, wherein, a spring part is supported on housing G or on connecting part A.
Further: described elastic device F and connecting part A connect as one.
Further: described housing G is the housing of electrical insulating material.

Embodiment
Fig. 2 there is shown the principle view of the elastic connection terminal 1 of the shock-resistant electric current of the preferred embodiment of utility model at section.It is applicable to for without instrument conductor L is installed.
The elastic connection terminal 1 of this shock-resistant electric current has housing G under assembled state, and this housing has the introduction hole for conductor.This housing G is schematically shown in broken lines.
Connecting part A is arranged in housing G, and the material of described connecting part is the material with conducting function.In addition, elastic device F is arranged in housing, and described elastic device does not stop conductor L to insert binding post 1, and the meeting conductor L that extruding is inserted in the direction of A shown in connecting part contacts with connecting part after conductor L inserts binding post 1; Described elastic device is a kind of elastic spring or similar object.Described elastic device self can design to obtain also bootable electric current, and contacts with connecting part A, to guarantee better conduction.
In embodiment, described connecting part A has multiple protruding E, and in the time having inserted conductor, described projection is connected with conductor L conduction by elastic device F.
Guarantee to produce the contact zone of sufficient amount by multiple projections, multiple projections conductor L that also firmly contact is not inserted completely.Thereby improve impulse current bearing capacity, and avoid melting welding.In addition, this layout also allows to hold and firmly contact conductor and the flexible conductor of different-diameter.
Fig. 3 is in sectional drawing mode, and Fig. 5 is the embodiment that shows connecting part A in stereogram mode.This connecting part A can be by bending and punching press simply by sheet forming.At this, connecting part A has three projections.The protruding E X illustrating in Fig. 3 represents, and amplifies and at length show in Fig. 4.
As shown in Figure 2, elastic device F is both legs formula spring in an embodiment, and a part for spring is supported on housing G.Alternatively or additionally, elastic device F also can be supported on wire connecting portion section A.If especially elastic device is supported by connecting part A, this support also can be used to guide current, that is to say, between conductor L and wire connecting portion section A, has formed another contact zone by elastic device F.
Elastic device F and connecting part A for example can be designed to one, therefore part cost can be down to minimumly, therefore save on the one hand cost.On the other hand, also have elastic characteristic if be used to provide the connecting part of high current carrying capacity, be also favourable to two parts or multipart variant simultaneously.
Further preferably, housing G material is insulating material, therefore can contact non-dangerously housing when mounted with after installing.
In addition, multiple projections can prevent from extracting the conductor L of insertion, and for this reason, its edge is set to blade-like.At this, by the extruding of elastic device F, projection has been pressed in conductor L to a certain extent, and therefore it no longer can pull out easily from elastic connection terminal 1.Although can be set to the direction inclination advancing to conductor in blade-like edge, this inclination is disadvantageous for dismounting.
In further preferred embodiment, as shown in Fig. 2 to 7, the elastic connection terminal 1 of shock-resistant electric current has at least 3 protruding E.By at least 3 protruding E are provided, guarantee to be always formed to rare two contact zones in the time that conductor L does not insert completely.Especially in the time that conductor L correctly inserts, form 3 or more contact zone, therefore reduce local (impact) current density, and therefore electric current raising can not cause welding yet.
Again further preferably, these protruding E have sharp-pointed variant part.At this, described sharp-pointed variant part is used for contacting and holding the conductor L towards connecting part A, and therefore sharp-pointed variant part also guarantees reliable contact because can break through the oxide layer that may exist conductor L on.
Fig. 6 and 7 shows being connected of connecting part A and cable sleeve interface K, for example, can be applicable in overvoltage protection equipment.
By the present embodiment, a kind of elastic connection terminal can be provided, its shock-resistant electric current and can hold the conductor of number of different types, is not easy to welding in addition.
