Description
Technical Field
The utility model relates to a static contact technical field specifically is a static contact that suitability is high.
Background
The static contact is a key component of the high-voltage switch, the connection and disconnection of the high-voltage switch are realized by the static contact, and the service life of the high-voltage switch determines the service life of the high-voltage switch and further determines the safe operation of a high-voltage transmission and transformation power grid. The contact generates pressing force on the moving contact by means of self rigidity during working, therefore, contact parts need to have high strength and rigidity besides high electric conductivity, most of the existing static contacts can only be installed according to the same specification when being installed in a matching mode with the moving contact, and the adaptability is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a static contact that suitability is high to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the fixed contact with high adaptability comprises a fixed contact and a moving contact, wherein one end of the moving contact is inserted in a slot formed in one end of the fixed contact in a sliding and inserting mode, a plurality of annular grooves are sequentially formed in the inner wall of the fixed contact, an annular spring is clamped in each annular groove, and the inner ring of each annular spring is in movable contact with the outer wall of one end, inserted into the slot, of the moving contact.
As an optimized technical scheme of the utility model, a plurality of the quantity of ring channel is two, and the quantity of ring channel is the same with the quantity of annular spring.
As an optimal technical scheme of the utility model, the external diameter of slot is greater than annular spring's internal diameter, and is less than annular spring's external diameter.
As an optimal technical scheme of the utility model, the outer wall of static contact is fixed to have cup jointed the installation cover seat, the four corners department of installation cover seat is equipped with the mounting hole that is array distribution, the mounting hole is for running through the form.
Compared with the prior art, the beneficial effects of the utility model are that:
the ring channel inside callipers is equipped with annular spring, annular spring's inner circle and the one end outer wall movable contact that the moving contact inserted the slot, the external diameter of slot is greater than annular spring's internal diameter, and be less than annular spring's external diameter, there is certain elasticity clamping-force through the annular spring groove that is equipped with at the ring channel inner wall, can tighten the centre gripping to moving contact male one end, thereby realize static contact and moving contact after the grafting installation finishes, it is more firm, thereby can install to the moving contact of different specifications, practicality and suitability are improved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a cross-sectional view of the middle static contact of the present invention.
In the figure: the device comprises a fixed contact 1, an insertion slot 11, an annular groove 12, an annular spring 13, a mounting sleeve seat 14, a mounting hole 15 and a movable contact 2.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a static contact with high adaptability comprises a static contact 1 and a moving contact 2, one end of the moving contact 2 is inserted in a slot 11 arranged at one end of the static contact 1 in a sliding manner, a plurality of annular grooves 12 are sequentially arranged on the inner wall of the static contact 1, an annular spring 13 is clamped in the annular grooves 12, the inner ring of the annular spring 13 is movably contacted with the outer wall of one end of the moving contact 2 inserted in the slot 11, the outer diameter of the slot 11 is larger than the inner diameter of the annular spring 13 and smaller than the outer diameter of the annular spring 13, when the static contact is used in daily life, one end of the moving contact 2 is inserted in the slot 11 arranged at the end of the static contact 1, after the moving contact 1 and the moving contact 2 are inserted in the slot 11, a certain elastic clamping force is generated through the annular spring groove 13 arranged on the inner wall of the annular groove 12, the inserted end of the moving contact 2 can be tightened and clamped, and therefore the static contact 1 and the moving contact 2 are completely inserted and installed, more firm to can install to the moving contact 2 of different specifications, improve practicality and suitability.
The number of the annular grooves 12 is two, the number of the annular grooves 12 is the same as that of the annular springs 13, and the clamping effect can be further improved by arranging the two annular springs 13.
The outer wall of the static contact 1 is fixedly sleeved with a mounting sleeve seat 14, mounting holes 15 distributed in an array form are formed in four corners of the mounting sleeve seat 14, the mounting holes 15 are in a penetrating form, and the mounting sleeve seat 14 and the mounting holes 15 are used for achieving mounting and fixing with other structures.
The working principle is as follows: the utility model discloses when daily use, insert the slot 11 that static contact 1 tip was equipped with one end of moving contact 2, after inserting in slot 11, have certain elasticity clamping-force through the annular spring groove 13 that is equipped with at the inner wall of ring channel 12, can tighten the centre gripping to the one end that moving contact 2 inserted to realize static contact 1 and moving contact 2 after the grafting installation finishes, more firm, thus can install to the moving contact 2 of different specifications, improve practicality and suitability;
the number of the annular grooves 12 is two, the number of the annular grooves 12 is the same as that of the annular springs 13, and the clamping effect can be further improved by arranging the two annular springs 13.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
