Embodiment

Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.

Main insulation seat on high-voltage vacuum load switch as a kind of in Fig. 1 and Fig. 2, comprise base 1 and top cover 2, base 1 sidewall is equipped with the dielectric pin 3 for installing inlet wire insulating base 10, dielectric pin 3 runs through base 1 sidewall, dielectric pin 3 two ends are equipped with annular groove 4, annular groove 4 is provided with jump ring 5, and dielectric pin 3 is spacing by jump ring 5.

By wearing dielectric pin 3 on base 1 sidewall, by dielectric pin 3, inlet wire insulating base 10 is installed on base 1, dielectric pin 3 runs through base 1 sidewall and its two ends are equipped with annular groove 4, annular groove 4 is provided with spacing jump ring 5, concrete structure as shown in Figure 4, like this run into need dismounting and change inlet wire insulating base 10 time, only the jump ring 5 at two ends need be disassembled, just dielectric pin 3 can be extracted out and realize disassembling section, in like manner first inlet wire insulating base 10 position is set during installation, again dielectric pin 3 is loaded onto through inlet wire insulating base 10, finally jump ring 5 being loaded on two ends, to realize axis spacing, whole process is fast simple and convenient, and without the need to top cover 2 is disassembled when dismounting and installation, very convenient, the efficiency of detachable maintaining can be provided.

Wherein preferably dielectric pin 3 and jump ring 5 are nylon material, nylon can play insulating effect incessantly, avoids conducting electricity the situation that there is potential safety hazard, and it has nontoxic, light weight, excellent mechanical strength, resistance to wear and corrosion resistance, and then more durable, need not change by regular carrying out.

If it is outside directly the end of shaft insulation to be caused to be exposed at base 1 shaft insulation and the such installation of jump ring 5, not only affect overall aesthetics, if jump ring 5 is directly exposed to outer easy appearance and damages, also easily occur that unexpected dropping causes occurring installing unstable problem simultaneously, therefore be provided with depressed part 6 at corresponding dielectric pin 3 place of base 1 sidewall, jump ring 5 is positioned at depressed part 6, the diameter of depressed part 6 is greater than the external diameter of jump ring 5, such dielectric pin 3 end can not be positioned at outside, and then overall structure is more attractive in appearance, certain protective effect can be played simultaneously, jump ring 5 is avoided to occur damaging or dropping, the external diameter that the diameter of depressed part 6 is greater than jump ring 5 is installation for the ease of jump ring 5 or dismounting, the external diameter of jump ring 5 accounts for 4/3 to five/5ths of depressed part 6 diameter, if the too large one side jump ring 5 of depressed part 6 diameter is easily deviate from, cause inoperative people also can not disassembled by jump ring 5 easily by instrument on the other hand, if the too little installation or removal that can affect jump ring 5 of depressed part 6 diameter, easily bring inconvenience, therefore preferably the external diameter of jump ring 5 accounts for the 4/5ths the most suitable of depressed part 6 diameter, best results.

Top cover 2 and base 1 are all connected by screw usually, if and directly to open screwed hole 9 on base 1 sidewall, the thickness of sidewall is needed to be greater than the diameter of screwed hole 9, and then increase production cost greatly, therefore the utility model base 1 inwall is provided with erection column 7, specifically as shown in Figure 3, erection column 7 and top cover 2 are provided with corresponding screwed hole 9 and are fixed by screw, while achieving a fixed connection, again can thinner by the sidewall design of base 1, effectively save production cost.

General base 1 outer surface is all flat smooth, the point of application is can not find like this when artificial carrying is taken, be not easy to take, therefore groove 8 is interval with on base 1 lateral wall, and groove 8 is uniformly distributed, thus make base 1 overall structure have more aesthetic property on the one hand, when artificial carrying is taken, hand can be grabbed and be realized impetus at groove 8 place on the other hand, therefore be more convenient to take, also can save production material to a certain extent simultaneously, reduce costs.

The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
