Abstract
The utility model 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.The static contact and arc-extinguish chamber of the utility model are 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 utility model relates to D.C. contactor technical field, the positioning of static contact connects in specifically a kind of D.C. contactor
Binding 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.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of positioning connection structure of static contact in D.C. contactor,
The height of static contact is positioned not against the step of arc-extinguish chamber, reduces the dependence to part size.
The technical solution of the utility model are 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.
The advantages of the utility model:
The static contact and arc-extinguish chamber of the utility model are interference fit, and it is anti-to be far longer than spring by the power that test presses
Power, static contact do not recycle the step of arc-extinguish chamber to carry out altitude location, reduce the dependence to part size, but match by interference
It closes structure and the height of positioning tool positioning static contact is supported to reduce cost of labor while guaranteeing contact force, make product
Consistency and quality reliability be improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
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.
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.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
