Abstract
The invention discloses a kind of positioning connection structures of static contact in D.C. contactor, static contact is located by connecting in arc-extinguish chamber, static contact standing block hole is provided in arc-extinguish chamber, static contact extend into the static contact standing block hole of arc-extinguish chamber and is interference fit connection with static contact standing block hole.Static contact and arc-extinguish chamber of the invention is interference fit, it is far longer than counter spring force by the power that test presses, static contact does not recycle the step of arc-extinguish chamber to carry out altitude location, reduce the dependence to part size, but by the height of over-surplus fit structure and support positioning tool positioning static contact, while guaranteeing contact force, cost of labor is reduced, the consistency and quality reliability of product is made to be improved.
Description
Technical field
The present invention relates to D.C. contactor technical field, the knot that is located by connecting of static contact in specifically a kind of D.C. contactor
Structure.
Background technique
Contact force is the key that D.C. contactor Quality Control point, and contact force is not only related with spring force, the prior art
It is that static contact is set in arc-extinguish chamber, static contact is mainly controlled by the step on the step and static contact of arc-extinguish chamber inner hole fixed
Position, this requires the dimensional accuracy of arc-extinguish chamber and static contact higher, and arc-extinguish chamber plastic part size is relatively difficult to guarantee, part consistency compared with
Difference causes contact force control difficult.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of positioning connection structures of static contact in D.C. contactor, disobey
The height of static contact is positioned by the step of arc-extinguish chamber, reduces the dependence to part size.
The technical solution of the present invention is as follows:
The positioning connection structure of static contact in a kind of D.C. contactor, the static contact are located by connecting in arc-extinguish chamber,
Static contact standing block hole is provided in the arc-extinguish chamber, the static contact is extend into the static contact standing block hole of arc-extinguish chamber
And it is connected with static contact standing block hole for interference fit.
Static contact support positioning tool, institute are provided in the arc-extinguish chamber and immediately below static contact standing block hole
The bottom end for the static contact stated is supported on static contact support positioning tool.
The static contact standing block hole is the hole that presses, and the static contact presses to the static contact standing block hole of arc-extinguish chamber
It is interior.
Advantages of the present invention:
Static contact and arc-extinguish chamber of the invention is interference fit, is far longer than counter spring force by the power that test presses, quiet
Contact does not recycle the step of arc-extinguish chamber to carry out altitude location, reduces the dependence to part size, but ties by interference fit
The height of structure and support positioning tool positioning static contact reduces cost of labor, makes the one of product while guaranteeing contact force
Cause property and reliability are improved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
See Fig. 1, the positioning connection structure of static contact, static contact 1 are located by connecting in arc-extinguish chamber 2 in a kind of D.C. contactor
It is interior, the static contact standing block hole for the pore structure that presses is provided in arc-extinguish chamber 2, static contact 1 presses to the static contact positioning of arc-extinguish chamber 2
It is interference fit connection in card hole and with static contact standing block hole, arc-extinguish chamber 2 is interior and is located at the underface of static contact standing block hole
It is provided with static contact support positioning tool 3, the bottom end of static contact 1 is supported on static contact support positioning tool 3.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
