Abstract
The utility model provides injection ceramic-vacuum tube, and it includes by the body of ceramic material injection molding, and outer surface of tube body is along its length provided with shape of threads or annular rib line, body end shrinks to form stair-stepping connection ring, and rib line depth is a, and body thickness is b, connection ring external diameter is c, b>a>c；Sealing ring is set with connection ring outer ring surface, sealing ring external diameter is equal to and body outer end diameter.This programme has the advantages that not oxidizable, good corrosion resistance using the body of ceramic material injection molding.
Description
Technical field
The utility model is related to electronic component technology field, refers in particular to a kind of injection ceramic-vacuum tube.
Background technology
Existing vacuum tube much be using metal material manufacture, its is oxidizable, corrosion-resistant, and intensity also compared with
It is low, also have what some were made of ceramic material, but existing ceramic vacuum pipe outer wall is smooth-going type mostly, its intensity is general；
End uses truncation type, is unfavorable for external.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and there is provided a kind of not oxidizable, good corrosion resistance, strong
The high injection ceramic-vacuum tube of degree.
To achieve the above object, technical scheme provided by the utility model is：Be molded ceramic-vacuum tube, it include by
The body of ceramic material injection molding, outer surface of tube body is along its length provided with shape of threads or annular rib line, and body end is received
Contracting forms stair-stepping connection ring, and rib line depth is a, and body thickness is b, and connection ring external diameter is c, b>a>c；Connection ring outer shroud
Sealing ring is set with face, sealing ring external diameter is equal to and body outer end diameter.
Described connection ring external diameter is a quarter of body thickness.
Described rib line depth is 1st/1st to two/3rd of body thickness.
Arc rounding off is used between described rib line and body.
Described sealing ring is highly more than connection ring height.
The utility model is had not oxidizable, resistance to after using such scheme using the body of ceramic material injection molding
The good advantage of corrosivity, while making body bulk strength higher using the rib line of shape of threads or annular, pipe is easy to using sealing ring
Connect in vitro, connection ring, sealing ring are using tube length direction as height, then sealing ring is highly more than connection ring height, makes body
Its end has certain cushion space when external.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
Embodiment
With reference to all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is：Ginseng
See accompanying drawing 1 and accompanying drawing 2, the injection ceramic-vacuum tube described in the present embodiment includes the body 1 by ceramic material injection molding, manage
The outer surface of body 1 is along its length provided with shape of threads or annular rib line 2, and the depth of rib line 2 is 1st to two/3rd of the thickness of body 1
/ mono-, arc rounding off is used between described rib line 2 and body 1, the end of body 1 shrinks to form stair-stepping connection ring
3, the depth of rib line 2 is a, and the thickness of body 1 is b, and the external diameter of connection ring 3 is c, b>a>C, the described external diameter of connection ring 3 is thick for body 1
The a quarter of degree；Be set with sealing ring 4 on the outer ring surface of connection ring 3, the external diameter of sealing ring 4 be equal to the outer end diameter of body 1, it is described
The height of sealing ring 4 be more than the height of connection ring 3.The present embodiment using ceramic material injection molding body have it is not oxidizable,
The advantage of good corrosion resistance, while making body bulk strength higher using the rib line of shape of threads or annular, is easy to using sealing ring
Body is external, and connection ring, sealing ring are using tube length direction as height, then sealing ring is highly more than connection ring height, makes pipe
Its end has certain cushion space when connecing in vitro.
Embodiment described above is only the preferred embodiment of the utility model, not limits reality of the present utility model with this
Apply scope, therefore the change that all shape, principles according to the utility model are made, it all should cover in protection domain of the present utility model
It is interior.
