Abstract
The utility model discloses a cathode lead-out mounting structure of a high-power vacuum tube. The cathode lead-out mounting structure of the high-power vacuum tube includes an inner lead-out ring and an outer lead-out ring of the cathode of the vacuum tube, and one pair of connecting blocks mounted on the inner lead-out ring and the outer lead-out ring; the connecting blocks are rectangular block-shaped; screw thread holes used for connecting application equipment are formed at the middle portions of the connecting blocks; the front ends of the connecting blocks are provided with insertion slots which are clamped into and are welded on the inner lead-out ring and the outer lead-out ring; the rear ends of the connecting blocks are provided with cross-shaped embedding slots; and embedded blocks are arranged in the embedding slots. According to the cathode lead-out mounting structure of the high-power vacuum tube of the utility model, the connecting blocks can be firmly welded on the inner lead-out ring and the outer lead-out ring of the cathode, and therefore, the problem of poor contact caused by looseness can be solved; and with the adoption of the screw thread holes and the embedded blocks, requirements of connection structures of different application equipment can be satisfied.
Description
Technical field
The utility model relates to a kind of interconnection technique of negative electrode and application apparatus of electron tube, relates in particular to a kind of great-power electronic tube cathode and draws mounting structure.
Background technology
As shown in Figure 1, at present, the inside and outside ring (1,2) of drawing of the negative electrode of electron tube is connected with the general inside and outside lead-in wire cover (3,4) that uses of installation of application apparatus, is mainly that the traverse point that goes between in overlapping is welded in and draws on ring.
But the drawback of using lead-out wire cover to connect application apparatus is that this kind of syndeton is firm not, easily loosening, thereby cause loose contact, in long-time use, the cathode current of high power valve is large, power is high (general electric current is greater than 200A, and power is higher than 2kW), and the resistance of contact portion is large, too high causing of local temperature struck sparks, thereby burn the negative electrode of drawing ring and electron tube.
In addition, the connected mode of lead-out wire cover can only be satisfied with the application apparatus of negative electrode of the wire connecting electronic pipe of employing, and when application apparatus adopt be screw connection time just cannot realize connection, thereby dwindled the scope of application of electron tube.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of great-power electronic tube cathode and has drawn mounting structure.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: a kind of great-power electronic tube cathode is drawn mounting structure, comprises the inside and outside ring of drawing of negative electrode of electron tube, and is a pair ofly arranged on inside and outside contiguous block of drawing on ring; The rectangular bulk of described contiguous block and middle part are provided with for connecting the screwed hole of application apparatus, when the connector of application apparatus is employing screw, just can directly screw be realized to both connections through screwed hole.
The front end of this contiguous block has and snaps in and be welded in described inside and outside slot of drawing ring, the rear end of described contiguous block is also provided with the embedded groove of " ten " word shape, described embedded groove is along the length direction setting of contiguous block, and embedded block is installed in groove, described embedded block inside is provided with tapped through hole, and by screw, passed tapped through hole and be connected in the bottom land of embedded groove, described contiguous block adopts copper material to make.When the connector of application apparatus is employing electric wire, electric wire can be filled in to embedded groove, re-use screw lock embedded block electric wire is held out against on contiguous block.
Compared with prior art, the utility model adopts connecting block structure, and its front end directly snaps in to draw to encircle and goes up and weld, structure very firmly, on the other hand, when connecting application apparatus, contiguous block is provided with screwed hole and embedded block, wherein screwed hole can achieve a butt joint and adopt the application apparatus of screw terminals, embedded block can achieve a butt joint and adopt the application apparatus of terminal, has expanded utilization scope, and practical, easy for installation, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the partial enlarged drawing at A-A of the present utility model place.
Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 2,3, the great-power electronic tube cathode the utility model proposes is drawn mounting structure, comprise cathode for electron tube in draw ring 1 and draw ring 2 outward, inside draw ring 1 and draw outward to encircle on 2 a pair of contiguous block 3 is installed; Contiguous block 3 contiguous blocks 3 adopt copper material to make, and at right angles block, the middle part of contiguous block is provided with for connecting the screwed hole 31 of application apparatus, the front end of this contiguous block 3 has draws ring 1 in snapping in and being welded in and draws the slot 32 that encircles 2 outward, the rear end of contiguous block 3 is also provided with the embedded groove 33 of " ten " word shape, embedded groove 33 is along the length direction setting of contiguous block 3, and embedded block 4 is installed in groove, embedded block 4 inside are provided with tapped through hole 41, and by screw 5 through tapped through hole 41 and be connected in the bottom land of embedded groove 33.
In the utility model, during actual installation, for different application apparatuss, there is different methods of attachment, wherein screwed hole can achieve a butt joint and adopt the application apparatus of screw terminals, when application apparatus is that conducting wire connector is, the wire of application apparatus can be connected and is placed in embedded groove 33, then turn upper embedded block, embedded block 4 slides on the chute of embedded groove again, the bottom land of embedded groove also has one section of screw thread, like this when screw 5 is through after embedded block, directly be connected with the screw thread of embedded groove bottom land, thereby the conducting wire connector of application apparatus is clamped in embedded groove.
Above-described embodiment has only been expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the utility model patent and protection range should be as the criterion with appended claims.
