Abstract
The utility model discloses a contact box comprising a contact box main body and a mounting seat, wherein the contact box main body is an insulating cylinder body; the bottom of the contact box main body is fixed together with the mounting seat, and bosses are arranged at the fixed position; at least one mounting hole for being connected with a switchgear is formed on the inside wall of the top of the contact box main body; and an air outlet allowing gas to flow out of the contact box main body is formed on the side wall of the cylinder body close to the top of the contact box main body, and an air inlet is formed on the side wall of the cylinder body of the contact box main body corresponding to the air outlet in a transplacement manner. The contact box has good radiating performance, and the bottom of the contact box main body is fixed together with the mounting seat through the bosses so as to enhance the overall strength of the box body of the contact box for better satisfying the work requirements; and the contact box adopting the design also has the advantages of simple structure, low manufacture cost and wide application range.
Description
Technical field
The utility model relates to a kind of parts that are used for switchgear, particularly a kind of contact box.
Background technology
Common contact box is on being used for switchgear the time, normally with switchgear on conductor directly be connected, in use, be positioned at the contact box conductor inside and under the effect of electric current, can produce heat, because the structural limitations of contact box itself, the heat that conductor produced can not be very fast distribute from contact box inside, so just make that the heat of being assembled is increasing in the contact box box body, thereby the conductor that causes being positioned at the box body switchgear is oxidized, and the conductor resistance after oxidized increases, under the effect of electric current, promptly can produce bigger heat, so circulation, this switchgear is easy to short circuit, and security incident takes place; Simultaneously present contact box overall construction intensity is not high, particularly at the connecting portion of contact box agent structure and its mount pad, because intensity is not high, damages extremely easily.
Summary of the invention
The purpose of this utility model is to improve the defective of prior art and product, and provide a kind of and be widely used, good heat dissipation effect and the high contact box of box strength.
For achieving the above object, the utility model adopts following technical proposals:
A kind of contact box, described contact box comprises contact box main body and mount pad, described contact box main body is an insulating cylinder body; The bottom of described contact box main body and described mount pad are fixed together, and this fixed place is provided with a boss, and the effect of described boss is to strengthen the bottom of contact box main body and the intensity between the mount pad; Offer at least one on the inside top wall of described contact box main body and be used for the installing hole that is connected with switchgear, near being provided with the gas outlet that supplied gas flows out the contact box main body on the cylinder lateral wall of described contact box main body tip position, with the cylinder lateral wall of the corresponding contact box main body in described gas outlet on dislocation be provided with air inlet.
Further, described air inlet is provided with outward and imports cover, the two sides that cover an end of described importing cover and importing respectively with described airtight connection of contact box main body, the other end of described importing cover is provided with the opening that is used for air inlet.
The utility model is compared with existing product, has following actively useful effect:
1, set thermovent and heat dissipating housing can better be discharged to the heat that is produced in the box body outside the box body on the utility model, makes the heat dispersion of contact box promote greatly.
2, the bottom of contact box main body is fixed together by a boss and described mount pad, has strengthened the intensity of contact box box body greatly, makes it to have better met need of work.
3, simple in structure, be widely used low cost of manufacture.

Fig. 2 is a structural front view of the present utility model.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is a structure left view of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
Shown in Fig. 1 to 4, a kind of contact box, described contact box comprise contact box main body 1 and mount pad 2, and described contact box main body 1 is an insulating cylinder body; The bottom of described contact box main body 1 and described mount pad 2 are fixed together, and this fixed place is provided with a boss 3, and the effect of described boss 3 is to strengthen the bottom of contact box main body 1 and the intensity between the mount pad 2, makes it to have better met need of work.Offer one on the inside top wall of described contact box main body 1 and be used for the installing hole 11 that is connected with switchgear (figure slightly), this installing hole 11 cooperates with mount pad 2 contact box is installed on the switchgear.
Be provided with the gas outlet 12 that supplied gas flows out contact box main body 1 on the close cylinder lateral wall of described contact box main body 1 tip position, these gas outlet 12 usefulness flow out for the hot gas in the contact box main body 1; With the cylinder lateral wall of described gas outlet 12 corresponding contact box main bodys 1 on dislocation be provided with air inlet 13.
Described air inlet 13 outer being provided with import cover 4, an end of described importing cover 4 and importing cover 4 two sides respectively with described 1 airtight connection of contact box main body, the other end of described importing cover 4 is provided with the opening 41 that is used for air inlet.
In use, by importing cover 4 and the air inlet 13 that is positioned on the contact box main body 1 extraneous gas is imported into contact box, then gas flows out through being positioned at gas outlet set on the contact box main body 1 top sidewall 12, so just make heat in the contact box box body, taken out of in the contact box box body by this flowing gas, thereby reached the purpose that contact box is dispelled the heat.
In sum, execution mode described in the utility model only provides a kind of execution mode of the best, technology contents of the present utility model and technical characterstic disclose as above, yet the personage who is familiar with this technology still may be based on content that the utility model disclosed and done various replacement and the modifications that do not deviate from creation spirit of the present invention; Therefore, protection range of the present utility model is not limited to the technology contents that embodiment discloses, so all equivalences of doing according to shape of the present utility model, structure and principle change, all is encompassed in the protection range of the present utility model.
