Abstract
The utility model discloses a kind of vacuum feedthroughs, comprise the outer conductor being provided with standard N-type connecting head, the inner wire being built in outer conductor and the ceramic window being connected outer conductor and inner wire, described inner wire one end is built in outer conductor, and the other end is provided with outside thread.Described vacuum feedthroughs also comprises the conductor group that can coordinate with outer conductor.Described conductor group comprises some not identical conductors of length.Described some conductor inner chambers are provided with internal thread.The vacuum feedthroughs that the utility model proposes, inner wire can coordinate with the conductor of different length in conductor group, forms multiple selections that inner wire length is different, is applicable to the vacuum equipment cavity of different-thickness.The length of inner wire can change arbitrarily according to the demand of client, and does not affect performance.The convenient detection applying to distinct device.
Description
Technical field
The utility model belongs to electric power conveying corollary equipment technical field, particularly relates to a kind of vacuum feedthroughs.
Background technique
Vacuum feedthroughs is that a kind of chamber walls of can passing is to transmit the air locking of various electric power, electrical signal, motion, running, fluid and light beam etc.
Vacuum feedthroughs of the prior art, comprises the outer conductor being provided with standard N-type connecting head, the inner wire being built in outer conductor and the ceramic window being connected outer conductor and inner wire.Vacuum feedthroughs is mainly used on vacuum equipment, and one end is connected with other equipment by welding or Flange joint, and the other end is connected with detecting instrument by concentric cable.In testing process, a part for inner wire can be deep in vacuum equipment cavity, when electric current is through vacuum equipment cavity, its internal current size can be detected.But because the wall thickness of vacuum equipment cavity is indefinite, the length causing inner wire to go deep into will change, and the inner wire of vacuum feedthroughs of the prior art is all fixed length, is not suitable for any vacuum equipment thereupon, the use limiting it is promoted.
Summary of the invention
The purpose of this utility model is just to provide a kind of inner wire adjustable in length, is applicable to the vacuum feedthroughs of any vacuum equipment.
To achieve these goals, technical solutions of the utility model are as follows:
A kind of vacuum feedthroughs, comprise the outer conductor being provided with standard N-type connecting head, the inner wire being built in outer conductor and the ceramic window being connected outer conductor and inner wire, described inner wire one end is built in outer conductor, and the other end is provided with outside thread.
Further, described vacuum seal feedthrough also comprises the conductor group that can coordinate with outer conductor.
Further, described conductor group comprises some not identical conductors of length.
Further, described some conductor inner chambers are provided with internal thread.
Further, described inner wire one end is built in outer conductor, and the other end is provided with the first interface arrangment.
Further, described vacuum seal feedthrough also comprises the conductor group that can coordinate with outer conductor, described conductor group comprises some not identical conductors of length, and described some conductor inner chambers are provided with the second interface arrangment, and described first interface arrangment and the second interface arrangment can coordinate.
The vacuum feedthroughs that the utility model proposes, inner wire can coordinate with the conductor of different length in conductor group, forms multiple selections that inner wire length is different, is applicable to the vacuum equipment cavity of different-thickness.The length of inner wire can change arbitrarily according to the demand of client, and does not affect performance.The convenient detection applying to distinct device.
Accompanying drawing explanation
Fig. 1 is the structural representation of vacuum feedthroughs of the present utility model.
Shown in figure: 1, outer conductor; 2, ceramic window; 3, inner wire; 4, standard N-type connecting head; 5, outside thread.
Embodiment
Be described in further details technical solutions of the utility model below in conjunction with drawings and Examples, following examples are not formed restriction of the present utility model.
As shown in Figure 1, vacuum seal feedthrough of the present utility model, comprise be provided with standard N-type connecting head 4 outer conductor 1, be built in the inner wire 3 of outer conductor 1 and be connected the ceramic window 2 of outer conductor 1 and inner wire 3, wherein, this inner wire 3 one end is built in outer conductor 1, and the other end is provided with outside thread 5.
This outer conductor 1 is formed by multiple annulus is one-body molded, its center is provided with through hole, in the through hole at center, ceramic window 2 is installed, and inner wire 3 one end is built in outer conductor 1 chamber through ceramic window 2, the other end is protruding in outer conductor 1, and the outer wall stretching out in outer conductor 1 is provided with outside thread 5.
In addition, this vacuum seal feedthrough also comprises the conductor group that can coordinate with outer conductor 1.This conductor group comprises the not identical conductor of some length.Every root conductor inner chamber is provided with internal thread.Each conductor can be coordinated with the outside thread 5 of inner wire 3 by internal thread.The vacuum seal feedthrough that composition inner wire 3 length is different, can go deep in the vacuum equipment of different wall.
Mode above by be threaded inner wire 3 and conductor group is one of embodiment of the present utility model, can also have other embodiments, such as:
Inner wire 3 one end is built in outer conductor 1 chamber through ceramic window 2, and the other end is protruding in outer conductor 1, and the outer wall stretching out in outer conductor 1 is provided with the first interface arrangment, specifically, the part stretching out in outer conductor 1 is provided with projection.And the not identical some conductor inner chambers of length in conductor group are provided with the second interface arrangment, this first interface arrangment and the second interface arrangment can coordinate, specifically, the second interface arrangment is the groove ring of conductor inner chamber, and the projection of inner wire 3 can coordinate with the groove ring of conductor inner chamber.
About the length of conductor each in conductor group, can arrange according to actual needs, be not particularly limited.
Above embodiment is only in order to illustrate technological scheme of the present invention but not to be limited; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
