Abstract

The utility model discloses a sealed electronic box, sealed electronic box include box body and lid, adopt the rubber pad sealed between box body and the lid, and there is the hole of pounding in the side of box body. The sealed electronic box adopting the structure has reliable sealing performance and good universality, is suitable for cables with different thicknesses, and can be assembled into a larger box body as required.

Description

The sealing electronic box

The utility model discloses a kind of box, the electronic box of a kind of sealing specifically.

The interface circuit of computer control system is many, and this circuit connects various transducers at the observing and controlling scene, and connects realization control automatically by cable with computer.There are construction site, mine, factory building, storehouse, silo etc. in the observing and controlling scene.Such environment often has dust, aqueous vapor, corrosive gas, and interface circuit has damage effect, makes control system sensitivity reduction or Control Failure easily.The observing and controlling scene produces fuel gas sometimes in addition, and interface circuit produces electric spark and causes fire easily.So interface circuit requires to use the reliable electronic box of sealing property.At present the interface circuit of computer control system does not use sealing electronic box or its sealing property unreliable, makes the computer control system fluctuation of service thus, even causes damage.

The purpose of this utility model is to provide a kind of sealing electronic box, and this box body sealing property is reliable, and can determine the cable fairlead as required.

Sealing electronic box of the present utility model comprises box body and lid two parts, fixture is arranged at the bottom of box body, between box body and the lid rubber blanket is arranged, and adopt screw to make up, there are some circular knock down holes the side of box body, circular knock down hole is to be injection molded into some annular grooves in the side of box body, can form circular hole from the groove abate as required.

Slightly have the circular knock down hole of thin requirement can also be injection molded into the multi-layer annular groove for appropriate cable has, wherein the groove of internal layer is darker than outer field, can go ahead of the rest into aperture when the abate circular hole, can also form macropore during macropore if desired.

As improvement of the present utility model, be injected with bigger square groove in the side of box body, can form large-area square hole along the groove abate, the projection of two-layer ring-type is arranged in the outside of groove, between groove and annular projection, have 4 small circular knock down holes at least.When the bigger electronic box of needs, can between the projection of two-layer ring-type, place rubber blanket, abate small circular knock down hole also fixedly makes two boxes combine with screw, can guarantee good sealing property.All there is this structure other sides at box body, can realize the combination of many box bodys.

Sealing electronic box good seal performance of the present utility model, and the requirement of adaptation varying number and thickness cable pigtail.

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is the utility model sealing electronic box perspective view.

Fig. 2 is the AA partial sectional view of sealing electronic box shown in Figure 1.

By shown in Figure 1, a specific embodiment of the utility model sealing electronic box, comprise box body 1 and lid 2 two parts, fixture is arranged at the bottom of box body, box body and and the lid between rubber blanket 3 is arranged, and adopt the screw combination, the big side of box body and little side have 5 and 3 knock down holes 4 that are made of two-layer annular groove respectively.By shown in Figure 2, wherein the groove 5 of internal layer is darker than outer field groove 6, can guarantee to go ahead of the rest into aperture when the abate circular hole, can also form macropore during macropore if desired.Big side at box body is injected with bigger square groove 7, can form large-area square hole along the groove abate, the

projection

8,9 that two-layer ring-type is arranged in the outside of groove, 4 small circular knock down holes 10 are arranged between groove 7 and annular projection 8, when the bigger electronic box of needs, can place rubber blanket between the

projection

8,9 of two-layer ring-type, abate small circular knock down hole 10 also fixedly makes two boxes combine with screw, can guarantee good sealing property.
