Description
Technical field
The utility model relates to a kind of moving contact arms for low-tension switch cabinet, belong to moving contact arm technical field.
Background technique
Contact is one of critical component of device for switching, the main performance of device for switching and the length in service life, in very great Cheng
The quality of contact material is depended on degree.Contact material is usually required that with good electric conductivity, lower contact resistance, higher
Resistance fusion welding energy, higher resistance to arc erosion energy and anti-material transfer ability.By structure and work characteristics, can be divided into can break
Contact, moving contact and static contact three classes.Wherein moving contact is mainly made of moving contact arm and contact, and contact is mounted on moving contact
In the contact slot of arm, pass through contact and external contact.But current moving contact arm is general to be only equipped with contact slot in side, uses office
It is sex-limited big, and stability is poor when multiple contact arms stick together.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of moving contact arm for low-tension switch cabinet, this is dynamic
Contact arm is designed using bilateral symmetry, and two sides are equipped with contact slot, can select to use according to demand, small using limitation, and is set
There is hexagonal card slot, can effectively ensure that the relative stability of each contact arm when separating by hexagonal spacing block.
The utility model is realized by following proposal: a kind of moving contact arm for low-tension switch cabinet, by multiple dynamic touchings
Head arm unit is connected in series, and the left and right sides of each moving contact arm unit upper end is provided with contact slot, each dynamic touching
The lower part of head arm unit is provided with the through-hole that front and back penetrates through, and the outer ring of described through-hole the right and left is equipped with card slot, and cross bar is successively
Multiple moving contact arm units are together in series by the through-hole across multiple moving contact arm units, and adjacent two are described dynamic
It is separated between contact arm unit by spacing block, the spacing block is stuck in the card slot.
The card slot is corresponding with the shape of the spacing block.
The spacing block is hexagon, and the card slot is also hexagon.
The right and left of each spacing block is stuck in the card slot of the adjacent moving contact arm unit.
Two contact slots are symmetrical.
The utility model has the following beneficial effects:
1, a kind of moving contact arm for low-tension switch cabinet of the utility model is designed using bilateral symmetry, and two sides are equipped with touching
Point slot, can select to use according to demand, small using limitation；
2, a kind of moving contact arm for low-tension switch cabinet of the utility model is equipped with hexagonal card slot, passes through hexagonal spacing block point
Every when can effectively ensure that the relative stability of each contact arm.
Detailed description of the invention
Fig. 1 is that a kind of moving contact arm unit facing structure of moving contact arm for low-tension switch cabinet of the utility model is illustrated
Figure.
Fig. 2 is that a kind of multiple moving contact arm units of moving contact arm for low-tension switch cabinet of the utility model connect side view
Structural schematic diagram.
In figure: 1 is moving contact arm unit, and 2 be contact slot, and 3 be through-hole, and 4 be card slot, and 5 be cross bar, and 6 be spacing block.
Specific embodiment
Below with reference to Fig. 1-2, the present invention will be further described, but scope of protection of the utility model is not limited in described
Hold.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description
Language "front", "rear", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to court
To or far from geometric center of specific component direction, and attached drawing is all made of very simplified form and uses non-accurate ratio
Rate, only to convenient, lucidly aid illustration the utility model embodiment purpose.
For clarity, not describing whole features of practical embodiments, in the following description, it is not described in detail well known function
And structure, because they can make the utility model chaotic due to unnecessary details, it will be understood that in any practical embodiments
Exploitation in, it is necessary to make a large amount of implementation details to realize the specific objective of developer, such as according to related system or related quotient
The limitation of industry changes into another embodiment by one embodiment, additionally, it should think this development may be it is complicated and
It is time-consuming, but to those skilled in the art it is only routine work.
A kind of moving contact arm for low-tension switch cabinet, is connected in series by multiple moving contact arm units 1, each moving contact
The left and right sides of 1 upper end of arm unit is provided with contact slot 2, and the lower part of each moving contact arm unit 1 is provided with what front and back penetrated through
The outer ring of through-hole 3,3 the right and left of through-hole is equipped with card slot 4, and the through-hole 3 that cross bar 5 sequentially passes through multiple moving contact arm units 1 will be more
A moving contact arm unit 1 is together in series, and is separated between two adjacent moving contact arm units 1 by spacing block 6, and spacing block 6 blocks
In card slot 4.
Card slot 4 is corresponding with the shape of spacing block 6.
Spacing block 6 is hexagon, and card slot 4 is also hexagon.
The right and left of each spacing block 6 is stuck in the card slot 4 of adjacent moving contact arm unit 1.
Two contact slots 2 are symmetrical.
Although having done more detailed elaboration to the technical solution of the utility model and having enumerated, it should be understood that for
For those skilled in the art, modifications to the embodiments described above may be made or uses equivalent alternative solution, this skill to this field
Be for art personnel it is clear that on the basis of without departing from the spirit of the present invention these modifications or improvements, belong to
In the range of the requires of the utility model protection.
