Abstract
The invention discloses a load switch upper contact base, comprising a fixing base and a contact. The fixing base is integrally formed by a conductive column and an upper pole column. The outer wall of the upper pole column is fixedly provided with a support plate. The bottom of the support plate is provided with a protruding plate extending downward. The protruding plate is provided with a plurality of bulges. The protruding plate is fixed with the upper pole column through a holding pin. The conductive column is provided with an installing hole. The upper pole column is provided with a threaded hole. The contact is fixed in the installing hole. The top end of the contact extends out of the installing hole. The bottom end of the contact extends to the threaded hole of the upper pole column. The load switch upper contact base is advantaged in that the contact is fixed in the installing hole of the conductive column, that is, the fixing base and the contact are in an integrated structure, the upper contact base is firm in structure and good in stability, and is not easy to damage. Manufacturing cost of the load switch upper contact base in the structure is reduced.
Description
Technical field
The present invention relates to on-load switch technical field, is specifically a kind of on-load switch upper contact head seat.
Background technology
On-load switch is a kind of device for switching between circuit breaker and isolating switch, has simple arc-control device, can cut off rated load current and certain overload current, but can not cutting-off of short-circuit electric current.
The upper contact head seat of on-load switch is the important component part of on-load switch, and the structure of the on-load switch upper contact head seat of prior art generally comprises upper contact head seat main body and contact, contact base main body and contact detachable, namely contact base main body and contact are not integrative-structures, in use often there is following problem: install insecure, easily produce loosening during installation, the time has been grown and has also easily damaged, and the upper contact head seat manufacturing cost of the on-load switch of split-type structural is high.
Summary of the invention
In view of the defect of above-mentioned prior art, the object of the invention is to: provide a kind of and install firmly, long service life and the on-load switch upper contact head seat of low cost of manufacture.
Technical solution of the present invention is: on-load switch upper contact head seat, comprise holder and contact, described holder by conductive pole and upper pole one-body molded, the outer wall of described upper pole is fixed with supporting bracket, the bottom of described supporting bracket has the flange to downward-extension, described flange has multiple projection, and described flange is fixed by holding pin and upper pole; Described conductive pole has an installing hole, described upper pole has a screwed hole, described contact is fixed in installing hole, and described installing hole is stretched out on the top of described contact, the bottom of described contact extends in the screwed hole of pole, be provided with insulated ring in the installing hole of described conductive pole, the bottom cover of described contact has insulator.
Further, the top of described conductive pole is provided with arc-shaped concave.
Further, groove is formed between two described projections.
Apply on-load switch upper contact head seat provided by the present invention, its beneficial effect is: contact is fixed in the installing hole of conductive pole, namely holder and contact are structure as a whole, sound construction, good stability, not fragile, and adopt the manufacturing cost of the on-load switch upper contact head seat of this structure to reduce.
Accompanying drawing explanation

Fig. 3 is another overall structure schematic diagram of the present invention.
Shown in figure: 1-holder, 11-conductive pole, 111-installing hole, the upper pole of 12-, 121-screwed hole, 2-contact, 3-supporting bracket, 31-flange, 311-is protruding, 4-holding pin, 5-insulated ring, 6-insulator, 7-arc-shaped concave, 8-groove.
Embodiment
For more intuitively, intactly understanding technical scheme of the present invention, existing just to carry out nonrestrictive feature description in conjunction with accompanying drawing of the present invention as follows:
As shown in Figure 1-Figure 3, on-load switch upper contact head seat, comprise holder 1 and contact 2, holder 1 by conductive pole 11 and upper pole 12 one-body molded, the outer wall of upper pole 12 is fixed with supporting bracket 3, the bottom of supporting bracket 3 has the flange 31 to downward-extension, and flange 31 has multiple protruding 311, and flange 31 is fixed by holding pin 4 and upper pole 12; Conductive pole 11 has an installing hole 111, even if conductive pole 11 has an opening, openings of sizes sets as required, upper pole 12 has a screwed hole 121, and contact 2 is fixed in installing hole 111, and described installing hole 111 is stretched out on the top of contact 2, the bottom of contact 2 extends in the screwed hole 121 of pole 12, be provided with insulated ring 5 in the installing hole 111 of conductive pole 11, the bottom cover of contact 2 has insulator 6, good insulating.
The top of conductive pole 11 is provided with arc-shaped concave 7, is formed with groove 8 between two projections 311, convenient installation.
On-load switch upper contact head seat provided by the present invention, contact 2 is fixed in the installing hole 111 of conductive pole 11, and namely holder 1 and contact 2 are structure as a whole, sound construction, good stability, not fragile, and adopt the manufacturing cost of the on-load switch upper contact head seat of this structure to reduce.
Certainly; these are only preferred embodiment of the present invention; non-ly therefore namely limit to the scope of the claims of the present invention, all utilizations specification of the present invention and graphic content institute be simple and easy modification and equivalent structure change for it, all should in like manner be contained within scope of patent protection of the present invention.
