Abstract
The invention relates to reduce the number of components and enhance cooling effect of a terminal conductor nearly T-shaped, supporting both ends of the terminal conductor with an insulating frame, and bringing the fixed side end of a vacuum valve into contact with its flat central part so as to conduct current. In addition, because the T-shaped reinforcing part 15c is provided, the surface area is so large that the effect as a heat dissipating fin is enhanced; thus, the generated heat in a vacuum valve is transmitted through a vacuum valve-retaining part 15d to the terminal conductor 15 and is radiated from its surface so that large current can be conducted.

In the main circuit of the as above vacuum switch in the past of structure, vacuum valve 1 be by vacuum valve mounting panel 10 through fixed terminal 7 and fixed terminal accessory 5 hanger bearings on Insulating frame 2.
Vacuum switch was generally said structure in the past, because the electrode of vacuum valve 1 is generally butt joint contact shape electrode, in case movable electrode (not shown) collides with fixed electrode (not shown) during input, and the very big impulsive force of generation in vacuum valve 1 then.At this moment because vacuum valve mounting panel 10 must have the intensity of the impact load when bearing big input, aspect material except that as also having the rigidity of corrosion resistant plate the conductor, so there is the too much problem of part number.
And, in the occasion of carrying out big electric current energising, though the corresponding sectional area that increases the electrode bar of electrode contact site is installed cooling fan and is increased area of dissipation in fixing and movable electrode rod up and down, is limited naturally from miniaturization, lightweight viewpoint.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide and a kind ofly reduce the part number and improve the terminal conductor of the vacuum switch of cooling effect.
The terminal conductor of vacuum switch of the present invention is, in described vacuum switch, vacuum valve is maintained at the inside of Insulating frame, being connected to the fixation side of described vacuum valve and the fixation side and the movable side terminal conductor of movable lateral electrode material derives to the outside, it is characterized in that, described fixation side terminal conductor is remained on the derivation side installation portion of being located at described Insulating frame inside respectively and is anti-ballisticly gone out the side installation portion, simultaneously, described fixation side terminal conductor has: be across the tabular portion between described derivation side installation portion and anti-ballistic two maintaining parts that go out the side installation portion; By described tabular portion to the outside leading-out portion of deriving of vacuum switch; The vacuum valve that contacts fixing with the axial end of the fixed side electrode parts of described vacuum valve between described two maintaining parts keeps face; And the inboard that keeps face at described vacuum valve is to the enhancing portion that the derivation direction of terminal conductor is extended, and described tabular portion, described leading-out portion and described enhancing portion are integrally formed by same material.
On the terminal conductor of above-mentioned vacuum switch, it is T font and axially outstanding to vacuum valve that the fixation side terminal conductor of described enhancing portion is made its cross section.
On the terminal conductor of above-mentioned vacuum switch, in described tabular portion, be provided with a plurality of heating panels.

Embodiment
Example 1:
Fig. 1-4 illustrates the vacuum switch of example 1 of the present invention, and wherein, Fig. 1 is the biopsy cavity marker devices side view of Insulating frame part, and Fig. 2 is Figure 1A-A direction view, and Fig. 3 is the vertical view of Fig. 1, and Fig. 4 is the B-B profile of Fig. 3.Among the figure, 1 is vacuum valve, 2 is Insulating frame, 3 have the fixed plate electrode of contact-making surface for the fixation side end that is located at vacuum valve at axial end portion, 4 is the movable electrode rod, 6 are the movable terminal accessory movable electrode rod 4 installed by clamping from both sides, and 15 is the fixation side terminal conductor, be across and be installed between the anterior installation portion 2a and rear portion installation portion 2b of Insulating frame 2.
Fixation side terminal conductor 15 be by: across plane 15a between installation portion 2a and the rear portion installation portion 2b forwardly, derive from columned leading-out portion 15b roughly to the outside from Insulating frame 2, and cross section on the general plane shape 15a of portion, that comprise the general plane shape 15a of portion is formed for T font roughly and at the axially extended enhancing 15c of portion of terminal conductor 15, in this example, plane 15a, leading-out portion 15b and the 15c of enhancing portion system is by the casting integral manufacturing.In addition, below the terminal conductor 15, keep face 15d, contact with the end face of the fixed plate electrode 3 of vacuum valve 1, and both are fixed with bolt as vacuum valve.
In addition, 11 is main circuit connection box (bottom is identical with superstructure, so the expression of bottom is partly omitted), and 12a is the deflection conductor, and 13 is insulating rod, and 14a is the terminal conductor of bottom.
Like this, because the cross section of terminal conductor 15 is made into roughly T font, so the intensity height also has conducting function in addition, so compared with prior art can reduce the part number significantly.And terminal conductor 15 also has the 15c of enhancing portion of T font except that plane 15a, so surface area is big, have the effect of radiator fan.Therefore, owing to keep face 15d directly to contact the vacuum valve of vacuum valve 1 and bottom, so the heat of generation promptly flows to terminal conductor 15 by vacuum valve maintenance face 15d and from the surface radiating of terminal conductor 15 in the vacuum valve 1.So compared with prior art can carry out big electric current energising.
Example 2:
In addition, Fig. 5-7 represents example 2, and its structure is identical with aforementioned example 1, but in the both sides of the 15c of enhancing portion of terminal conductor 15 big heating panel 15e and the little heating panel 15f with necessary area of dissipation is installed.This big heating panel 15e and little heating panel 15f other parts monoblock cast common and terminal conductor 15 forms.By this structure, compare with example 1 and can further enlarge powered-on capacity.
The present invention is owing to adopting said structure, so have following effect:
Owing in the both sides, front and back of Insulating frame terminal conductor is supported, and vacuum valve is directly installed on the bottom of terminal conductor, so the part number that can reduce conduction significantly and strengthen.
In addition, because the cross section that terminal conductor is strengthened portion makes roughly the T font and extends at length direction, thus the intensity height, and good heat dissipation effect.
Also have, because tabular portion, leading-out portion and enhancing portion are that same material is integrally formed, so can reduce the part number significantly.
In addition, owing to be provided with a plurality of heating panels in tabular portion, so can further improve radiating effect.
