Connection device and gas-filling cabinet, in the utility model, the moved end of insulator, breaker on gas-filling cabinet passes through spring touch finger and connects, bullet
Spring fingertip can be with deformation occurs, and then reduces the requirement to the relative mounting location of insulator and moved end, reduces installation difficulty.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also
Other attached drawings can be obtained according to the attached drawing of offer.
Fig. 1 is a kind of cross-section diagram of the attachment device for connecting insulator and breaker provided in an embodiment of the present invention.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model embodiment provides a kind of attachment device for connecting insulator and breaker, including is set to
The moved end of insulator and breaker on gas-filling cabinet offers annular groove, the annular on the moved end inner ring wall of the breaker
Spring touch finger is provided in slot, the insulator is sheathed on the spring touch finger inner ring.
Wherein, spring touch finger (canted coil spring) is heavy current can be transmitted in small space, while being also used as purely
Mechanical connection.It uses no any restrictions, is suitble to use under a variety of mesohigh environment either statically or dynamically.Spring touch finger
Size and independent wire circle make spring be suitable for various electrical contact designs, and with maximum contact point be optimal current-carrying
Ability is electrical or EMI shielding uses.Each coil changes independent compensation contact and surface, it allows between wider accessory
Tolerance.Multiple contact points increase conductivity, while its use operation temperature is relatively low, so the service life is longer.
Spring touch finger advantage is as follows:
1, structure is simple, small in size, and materials are few, at low cost；Meet the requirement that device designs upper space small size, is suitable for
Compact design；Least number of components simplifies the design of interface unit.
2, Multi-contact, high concentrated force is, it can be achieved that almost lossless contact.Guarantee biggish current-carrying capacity；Good conductivity, electricity
Dynamic and thermostabilization is high.
3, the contact pressure of each contact point is not high, has good wearability.
4, unique structure makes it have spacious and comfortable working range；Allow to exist in contact surface compared with high tolerance；Processing is missed
Difference and rigging error have biggish adaptability, are more suitable for being mass produced.
Specifically, referring to Fig.1, Fig. 1 is the cross-section diagram of attachment device.The moved end 1 of breaker, is referred to as moving in Fig. 1
Contact, the insulator 2 on gas-filling cabinet, is referred to as stationary contact, is connected by spring touch finger 3.
Be provided with annular groove on moved end 1, be used for fixed spring fingertip, the longitudinal section of annular groove include but is not limited to ladder type,
Circular arc or V-type etc..
In the present embodiment, to moved end setting annular groove width with no restrictions, as long as can guarantee that spring touch finger is steady
Fixed is stuck in annular groove.
It is, however, preferable that the width of the annular groove is less than the outer diameter when spring touch finger is in undeformed state.Tool
Body, the width of annular groove is less than the outer diameter when spring touch finger is in undeformed state, and guarantee spring touch finger in this way is in shape
It is put into annular groove when change, then, when spring touch finger restores deformation, being stuck in annular groove tightly.
