Abstract
The utility model belongs to the field of electrical equipment, and relates to a switch, in particular to a porcelain bushing sleeve inside the switch. The porcelain bushing sleeve comprises a porcelain member and a conducting tube, a circular hollow structure is arranged in the middle of the porcelain member, the metal conducting tube is arranged inside the hollow structure and adhered to the side wall of the hollow structure, and two grooves are arranged on the left and the right of the outer side of the conducting tube. The porcelain bushing sleeve is characterized that the grooves are in V-shaped structures with openings outwards, further, the V-shaped structure occupies the area ranging from one second to two thirds of the section. When in use of the porcelain bushing sleeve, the porcelain member cannot be expanded to break along with rising of temperature.
Description
Technical field
The utility model relates to appliance field, relates to a kind of switch, specifically relates to a kind of insulator sleeve pipe of switch inside.
Background technology
Has the insulator sleeve pipe on the switch, the insulator sleeve pipe is the parts that connect contact, the outside has porcelain spare, has circular hollow structure in the middle of the porcelain spare, have the metallic contact tube that is adjacent to its sidewall in hollow structure inside, the conduction administration is bonding in hollow structure inside, for preventing that porcelain spare is risen brokenly, in the prior art, there is a kind of left and right sides, the outside of contact tube to have two grooves.Its cross section is square structure, have that contact tube intensity is low, the shortcoming of the anti-weak effect that rises brokenly.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provides in use a kind of, prevents to rise brokenly the insulator sleeve pipe of better effects if along with the temperature degree raises.
The technical solution of the utility model is achieved in that the insulator sleeve pipe, comprise porcelain spare and contact tube, has circular hollow structure in the middle of the described porcelain spare, has the metallic contact tube that is adjacent to its sidewall in hollow structure inside, the conduction administration is bonding in hollow structure inside, the left and right sides, the outside of described contact tube has two grooves, it is characterized in that: described groove is opening " V " shape structure outwardly.
Further incite somebody to action, described " V " shape structure occupies 1/2 of cross section---and 2/3.
The beneficial effects of the utility model are: such insulator sleeve pipe has in use, the advantage that raises and porcelain spare can not risen brokenly along with the temperature degree.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model insulator sleeve pipe.
Wherein: 1, porcelain spare 2, contact tube 3, groove
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of insulator sleeve pipe with " V " shape opening, comprise porcelain spare 1 and contact tube 2, has circular hollow structure in the middle of the described porcelain spare 1, has the metallic contact tube 2 that is adjacent to its sidewall in hollow structure inside, contact tube 2 linchpins are bonding in hollow structure inside, and the left and right sides, the outside of described contact tube 2 has two grooves 3, it is characterized in that: described groove 3 is opening " V " shape structures outwardly.
Further incite somebody to action, described " V " shape structure occupies 1/2 of cross section---and 2/3.
Such groove has anti-tensioner better effects if, can not influence the effect of contact tube intensity.
Claims (2)
