Abstract
The utility model relates to a special-shaped soldering lug for vacuum tubes. The soldering lug comprises a thin-wall ring, wherein a plurality of recesses are distributed in the inner wall of the ring. The soldering lug has the beneficial effects that the soldering lug is consistent with moving and fixed contacts of vacuum tubes and contact support brazing surfaces of the moving and fixed contacts in shape and size, without need of extra manual cutting, thus improving the production efficiency; and meanwhile, the brazing consistency is high and wastes generated due to nonuniform solder melting are unlikely to generate.
Description
Technical field
The utility model relates to weld tabs, particularly special-shaped weld tabs.
Background technology
Vacuum tube is that a kind of vial inside vacuumizes, and is beneficial to flowing of free electron, also can effectively reduce the electronic device of the oxidation loss of filament.As Fig. 1, it mainly is welded to form by moving conductive rod 1, fairlead 2, bellows 3, bellows shield cover 4, contact system 5, static conductive rod 9 orders.Wherein, contact system 5 comprises relative up and down moving contact 7 and fixed contact 8, and dynamic/static contact welds mutually with contact tray 6 separately.
Vacuum tube is complex-shaped, and dimension precision requirement is high.For each part of dimensional accuracy vacuum tube of guaranteeing inner vacuum tube member all in the hydrogen shield stove fine weldering form, in the hydrogen shield stove, the advantage of fine weldering is homogeneous heating, is out of shape littlely, easily guarantees dimensional accuracy, intensity is high.
Contact is the position that produces electric arc, extinguish arcs, and is all higher to the requirement of material and structure.On material, contact mostly adopts chromiumcopper, and copper and chromium respectively account for 50%.And structurally, the arc quenching effect that the different structure contact produces is different.
In actual production, what dynamic/static contact and contact tray adopted when fibre welds in the hydrogen shield stove is commercially available whole silver soldering sheet.During actual production, according to the size of dynamic/static contact and contact tray solder side, be tailored into the cross section shape of the above-mentioned fine face of weld and size with the silver soldering sheet is manual, then be positioned over solder side and carry out fibre and weld.This method production efficiency is low, and the weld tabs of hand cutting is not easy to fit fully with solder side, produces through welding back part air-tightness, and the finished product rate is low.
The utility model content
Through Improvement, now provide a kind of weld tabs when being applicable to vacuum tube dynamic/static contact and the fine weldering of contact tray for the problems referred to above applicant, not high to solve the dynamic and static contact of vacuum tube and to weld separately consistency during the fine weldering of contact tray, the problem that production efficiency is low.
The technical solution of the utility model is as follows:
The utility model comprises a thin wall circular, circle ring inner wall several concave stations that distribute.
Further:
4 concave stations of described circle ring inner wall distribution.
Described concave station is equally spaced.
Useful technique effect of the present utility model is:
In the vacuum tube actual production process, when the dynamic and static contact of vacuum tube and the fine weldering of the needs of contact tray separately, directly the utility model is held between dynamic and static contact and contact tray.With dynamic and static contact with contact tray fibre face of weld shape size is consistent separately, do not need extra hand cutting due to the utility model, enhance productivity.Simultaneously, fine weldering welding consistency is high, is not easy to produce the waste product that melts inhomogeneous generation because of scolder.
Description of drawings
Fig. 1 is that vacuum tube partly cuts open schematic diagram.
Fig. 2 is the utility model front view.
Wherein: 1 moving conductive rod 2 fairlead 3 bellowss
4 bellows shield cover 5 contact system 6 contact trays
7 moving contact 8 fixed contact 9 static conductive rod 10 annulus
11 concave stations.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
See Fig. 2, the utility model comprises a thin wall circular 10,4 concave stations 11 of annulus 10 inwalls distributions.Concave station 11 is equally spaced.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic conception of the present utility model, all should think to be included in the utility model.
