Abstract
The utility model discloses a dish-shaped stem structure for an electron tube, and the structure comprises a stem body. The structure is characterized in that the stem body is dish-shaped; the lower surface of the stem body is equipped with an exhaust pipe; the upper surface of the stem body is uniformly equipped with a plurality of bosses along the peripheral direction; a part, corresponding to the center of each boss, on the stem body is equipped with an electrode outgoing line; the upper part of each electrode outgoing line is led out by the corresponding boss; and a part, located on the upper surface of each boss, of the corresponding electrode outgoing line is fixedly sleeved by an outgoing line reinforcing loop. The structure is advantageous in that a larger current can be conducted during high-power output; the temperature of the stem is decreased; the working reliability of the electron tube is improved during high-power output; and the power level and structural strength of an audio electron tube are improved.
Description
Technical field
The utility model relates to a kind of electron tube dish core column structure.
Background technology
Existing Electron tube core column structure is by stem stem body and is multiple electrode outlet lines that comb type is arranged on stem stem and forms, and stem stem body is cylindric.Its structural strength is low, easily causes breakage, and the electrode outlet line diameter of this kind of core column structure is less, can not meet the requirement of the large electric current of relatively high power electron tube admittance.Because comb core post electrode outlet line length is longer, the heat on stem stem is difficult for outside delivery line, produces thus higher stem stem temperature and easily makes the glass phenomenon that produces electrolysis, and easily causes and bursts hidden danger.
Utility model content
Technical scheme to be solved in the utility model provide a kind of structural strength high, not fragile, can the large electric current of admittance, the glass electron tube dish core column structure that is difficult for bursting.
The technical solution of the utility model is:
A kind of electron tube dish core column structure, comprise stem stem body, its special character is: described stem stem body is dish, be provided with blast pipe at stem stem body lower surface, described stem stem upper surface is along the circumferential direction evenly provided with multiple boss, on stem stem body, the center of corresponding described boss arranges electrode outlet line, and described electrode outlet line top is drawn by described boss, is positioned at boss upper surface place and is set with and is installed with lead-out wire reinforcing ring on electrode outlet line.
The beneficial effects of the utility model are:
It is dish-shaped tabular stem stem that this electron tube dish core column structure changes cylindrical shape comb core post, electrode outlet line is along the circumferential direction arranged, can the larger electric current of admittance when high-power output, reduce stem stem temperature, improve the functional reliability of electron tube in the time of high-power output, improve power grade and the structural strength of audio electronics pipe simultaneously, and solved the problem that glass easily bursts.
Accompanying drawing explanation
Fig. 1 is the dish-like stem stem schematic diagram of the utility model;
Fig. 2 is the vertical view of Fig. 1.
In figure: 1-stem stem body, 101-boss, 102-blast pipe, 2-electrode outlet line, 3-lead-out wire reinforcing ring.
Embodiment
As shown in the figure, the electron tube dish core column structure that the utility model relates to, comprises dish-shaped stem stem body 1, is provided with blast pipe 102 in stem stem body 1 lower surface center, described stem stem body 1 upper surface is along the circumferential direction evenly provided with multiple boss 101, and the present embodiment is take six as example.On stem stem body 1, the center of corresponding described boss 101 is installed with electrode outlet line 2, and described electrode outlet line 2 tops are drawn by described boss, is positioned at boss 101 upper surface places and is set with and is installed with lead-out wire reinforcing ring 3 on electrode outlet line 2.
