Abstract
The utility model relates to a kind of switch, belongs to electrical connection apparatus field, is specifically related to a kind of vacuum switch tube with bellows.Comprise: to cover with moved end and quiet end cap forms the porcelain cylinder of seal chamber, by the interconnective dynamic tube core of contact and quiet bar in porcelain cylinder, the two ends that described dynamic tube core and quiet bar do not contact are each passed through described moved end lid and quiet end cap, the inwall of described moved end lid is fixed with a bellows, and the other end of this bellows is fixed on described dynamic tube core near one end of contact.Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. good insulating, working stability.
Description
Technical field
The utility model relates to a kind of switch, belongs to electrical connection apparatus field, is specifically related to a kind of vacuum switch tube with bellows.
Background technology
Vacuum switch tube cut-offs device as circuit, is widely used.At present, vacuum switch tube of the prior art, complex structure, poor insulativity, job insecurity, and when switch disconnects, the back fire thing of contact easily pollutes porcelain cylinder inwall.
Utility model content
The utility model mainly solves the above-mentioned technical problem existing for prior art.Provide a kind of vacuum switch tube with bellows, this vacuum switch tube is reasonable in design, and structure is simply and completely practical, and good insulating, working stability.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of vacuum switch tube with bellows, comprise: to cover with moved end and quiet end cap forms the porcelain cylinder of seal chamber, by the interconnective dynamic tube core of contact and quiet bar in porcelain cylinder, the two ends that described dynamic tube core and quiet bar do not contact are each passed through described moved end lid and quiet end cap, the inwall of described moved end lid is fixed with a bellows, and the other end of this bellows is fixed on described dynamic tube core near one end of contact.
Optimize, above-mentioned a kind of vacuum switch tube with bellows, in described porcelain cylinder, also have a protective cover being positioned at described contact outer.
Optimize, above-mentioned a kind of vacuum switch tube with bellows, the outer wall of described protective cover is provided with the adsorbent for dehumidifying.
Optimize, above-mentioned a kind of vacuum switch tube with bellows, described quiet end cap and moved end are covered the position that connects with described porcelain cylinder is respectively provided with and are disclosed circle.
Optimize, above-mentioned a kind of vacuum switch tube with bellows, the side of described protective cover is welded on described quiet end cap.
Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. good insulating, working stability.
Accompanying drawing explanation
Fig. 1 is utility model structural representation.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.Moved end lid 1, quiet end cap 2, porcelain cylinder 3, contact 4, dynamic tube core 5, quiet bar 6, bellows 7, protective cover 8, adsorbent 9, solder circle 10 in figure.
Embodiment:
As shown in Figure 1, a kind of vacuum switch tube with bellows, it is characterized in that, comprise: with moved end cover 1 and quiet end cap 2 form the porcelain cylinder 3 of seal chamber, by the interconnective dynamic tube core 5 of contact 4 and quiet bar 6 in porcelain cylinder 3, the two ends that dynamic tube core 5 and quiet bar 6 do not contact are each passed through moved end lid 1 and quiet end cap 2, the inwall of moved end lid 1 is fixed with a bellows 7, the other end of this bellows 7 is fixed on dynamic tube core 5 near one end of contact 4, a protective cover 8 being positioned at contact 4 outside is also had in porcelain cylinder 3, the side of protective cover 8 is welded on quiet end cap 2, the outer wall of protective cover 8 is provided with the adsorbent 9 for dehumidifying, the position that quiet end cap 2 and moved end lid 1 connect with porcelain cylinder 3 is respectively provided with solder circle 10.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the term such as moved end lid 1, quiet end cap 2, porcelain cylinder 3, contact 4, dynamic tube core 5, quiet bar 6, bellows 7, protective cover 8, adsorbent 9, solder circle 10 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
