Description
Technical field
The direct-insert spring type (Schenkelfeder) that the utility model is related to a kind of for being arranged in connecting terminal.This
Outside, the utility model is related to a kind of connecting terminals with this direct-insert spring type.
Background technology
Direct-insert spring type in various embodiments known in the state of the art.Normally, direct-insert spring type has the
One leg and the second leg, one of leg can be structured as clamping leg and another leg and can be structured as contact leg
Portion.The two legs are connected by the mutual single type of section of spring bow or bending mostly.However the spring bow may be constructed
The weak spot of direct-insert spring type, because the excessive loads direct-insert spring type in spring bow can be sent out in the region of spring bow
Life fractures.This point in order to prevent, can construct stopper section in connecting terminal, and stopper section limits or defines the movement of leg simultaneously
And therefore limit or define the bending angle of spring bow.However the movement of leg is limited by the whole length through leg,
The elastic force that can be applied by leg is also limited, this is especially in the case where being clamped or connecting the conductor with larger conductors cross
It is unfavorable.
Utility model content
Therefore, the purpose of this utility model is that proposing a kind of direct-insert spring type and electric connecting terminals, pass through direct insertion bullet
The shortcomings that spring and electric connecting terminals are mentioned before capable of overcoming.
According to the utility model, which is realized by the feature of independent claims.The suitable of the utility model is set
Meter scheme and advantageous extended mode provide in the dependent claims.
Direct-insert spring type according to the present utility model with the first leg, the second leg and spring bow with radius R1,
First leg and the second leg are interconnected by spring bow, wherein the first leg includes the bending section for having radius R2, second
Leg includes the bending section for having radius R3, wherein the bending section of the bending section of the first leg and the second leg constructs in this way, i.e.,
The bending section of the first leg is resisted against on the bending section of the second leg during manipulating direct-insert spring type.
The feature of direct-insert spring type according to the present utility model particularly in, design direct-insert spring type in this way, i.e., the two
Leg can be significantly bent relative to one another in this way, until the two legs on its bending section against each other, without
Fractureing for spring bow is caused with regard to this.Design direct-insert spring type in this way reaches when leg is abutted together on its bending section
The maximum value of stress load on the radius of spring bow.If the two legs in the region of its bending section against each other and
It is held against in the region of its bending section, further load is assigned to the phase for the leg that interaction is lighted from this time
Answer bending section.Then elastic force no longer applies on entire leg, but the freedom from bending section to leg of elastic force from leg is last
It holds in the region extended and applies, because at this moment the region can be further bent upwards to the side of corresponding another leg, to
These regions can further move relative to one another from corresponding bending section to the corresponding free terminal of leg.It waits for through direct insertion bullet
Thus the elastic force that spring applies can be increased further, this is particularly connecting or be clamped the conductor with big conductors cross
In the case of be advantageous.Relative to usually used direct-insert spring type, therefore can be on its bending section by two legs
Against with the possibility being close to and realize that further strength increases in spring characteristic line, without making direct-insert spring type,
The excessive loads especially in the region of spring bow.It therefore, can be relative to conventional direct-insert spring type by direct-insert spring type
Further increase the danger that the elastic force of direct-insert spring type fractures without direct-insert spring type.
It being preferably provided with, the radius R2 of the bending section of the first leg is same as the radius R3 of the bending section of the second leg big, by
This can be in the bending section of leg against realizing the load evenly distributed on leg in the process.
Further preferably setting, the radius R2 of the bending section of the legs radius R1≤first of bending section and/or bending section
The radius R3 of the bending section of the legs radius R1≤second.Therefore spring bow preferably has less than the radius of the bending section of leg, by
This is particularly capable of realizing the stress distribution especially optimized in direct-insert spring type, because when it operates (auf in module
Block arbeiten) when namely its when being abutted together and being close to mutually, bending section being capable of mutual phase demodulation.
Particularly preferably it is arranged herein, the ratio of 1/5≤radius R1/ radiuses R2≤1/1.5 is constructed in direct-insert spring type
And/or the ratio of 1/5≤radius R1/ radiuses R3≤1/1.5.
Bending section preferable configuration distance from spring bow to the bending section of the first leg and/or from spring bow to the second leg
H, wherein the ratio of 1/5≤radius R1/ distances H≤1/1 can be constructed herein.If ratio R1/H is more than 1/1, direct insertion bullet
The manufacture of spring can be difficult.
Further preferably setting, from spring bow to the midpoint of the bending section of the first leg and/or from spring bow to the second leg
The midpoint construction distance A2 of the bending section in portion and the free terminal of the midpoint of the bending section of the first leg and the first leg it
Between and/or between the midpoint and the free terminal of the second leg of the bending section of the second leg construct distance A3, wherein it is preferred that setting
Set the ratio of 1/2≤distance A2/ distances A3≤1/0.5.This ratio if there is A2 relative to A3 can then utilize leg
The length corresponding to distance A3 of shortening further increase elastic force when the bending section of two legs contacts with each other, to compared with
Higher contact force is capable of providing under conditions of big conductors cross.
In order to improve the installation easiness of direct-insert spring type, further preferably it is arranged, direct-insert spring type is configured to
Symmetrically.Under conditions of symmetrical structure, the two legs length preferably having the same and bending section is having the same
Radius is simultaneously arranged along the length of leg in identical height.
In addition, the purpose of this utility model realizes that the connecting terminal has by the connecting terminal for connecting electric conductor
Accommodating chamber, the busbar accommodated in accommodating chamber and the direct-insert spring type accommodated in accommodating chamber, the electricity being directed in accommodating chamber
Conductor can be clamped by direct-insert spring type relative to busbar, and wherein direct-insert spring type is constructed or extended as earlier mentioned.
By using the direct-insert spring type of front construction or extension such as, the accommodating chamber for direct-insert spring type can construct
To be particularly small in its size, because in the case of the direct-insert spring type of very little structure, in order to which conductor is clamped, especially
In order to which the conductor with larger conductors cross is clamped, sufficiently large contact force can also be applied.By that can be configured to especially
Small direct-insert spring type and thus, it is possible to be configured to especially small accommodating chamber, entire connecting terminal can be especially small.
