Abstract
The invention provides a junction box which is composed of a box body and a box cover. Four corners of the box body are provided with a step in a welding mode, and thread holes are placed on each step. Screw holes matched with the thread holes are placed on the box cover. A sealing strip is adhered to the rim on the inner side of the box cover. The whole junction box is fixed through screws, thereby being convenient to dissemble and assemble. Under the function of the sealing strip, the junction box can effectively prevent external dust from entering the junction box. Water-proof connectors placed on two sides of the junction box play a good role in sealing.
Description
Technical field
The present invention relates to technical field of electricity, particularly a kind of junction box of the connection for the production of mechanical part in the manufacture process and components of system as directed.
Background technology
Junction box is the terminal of distribution cable or optical cable, connects distribution cable or optical cable and subscriber's line part, and backbone is carried out branch, has important effect.Junction box can be installed in the narrow spaces such as crane span structure, casing, pipeline, cable trough, does not take effective usable floor area of building, and is easy for installation, do not need to block leader cable.Along with the development of modern manufacturing industry, electric and mechanical scale is more and more huger, and electric wiring becomes increasingly complex because the particularity of some mechanical part, can't with line with its directly and control system couple together.Such as the Working cart that has will move, we need to be connected to systems control division with the motor lines on the dolly, holding wire etc. and divide, and make mistakes easily when circuit is various, and line partly is difficult for tightening up, operating process is inconvenient, breaks down easily and security incident.
Summary of the invention
In order to overcome the defective of prior art, the invention provides following technical scheme:
A kind of junction box is comprised of box body and lid, and a step is respectively welded at four angles on the described box body, is equipped with screwed hole on each step, and described lid is provided with the screw hole with the screwed hole coupling, and sealing strip is posted in the inside edge of described lid.
As preferably, step place, both sides is welded with 2 guide rails assembling supports in the box body, and described guide rails assembling support is provided with some guide rails assembling holes for the mounting terminal guide rail, but the installation site of described guide rails assembling hole free adjustment guide rail.
As preferably, a side of described box body has some through wires holes for the water joint that the threading flexible pipe uses is installed, and the bottom punching of box body has 4 box body installing holes.
The beneficial effect that the present invention brings is: junction box all adopts screw to fix, easy accessibility, and because the effect of sealing strip can prevent effectively that outside dust from entering junction box, by both sides water joint is installed, play good sealing function.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
As shown in Figures 1 to 4, a kind of junction box, formed by box body 1 and lid 7, four angles respectively are welded with a step on the described box body 1, attacked screwed hole 2 on each step, screwed hole 2 be used for lid 7 on screw hole 6 coupling, by screw lid 7 is fixed on the box body 1, sealing strip is posted in inside edge at lid 7, and the contact portion of lid 7 and box body 1 is played dustproof effect.Being welded with 2 guide rails assembling supports, 4 guide rails assembling supports, 4 upper punches at step place, box body 1 interior both sides has several guide rails assembling holes, is used for the mounting terminal guide rail, and the several installing holes on the guide rails assembling support 4, is free to regulate the installation site of guide rail.Side at box body 1 has several through wires holes 5, is used for installing the water joint that the threading flexible pipe is used, and the bottom punching of box body has 4 box body installing holes 3, is used for above the junction box mounting plate.
The described junction box of the embodiment of the invention all adopts screw to fix, easy accessibility, and because the effect of sealing strip can prevent effectively that outside dust from entering junction box, by both sides water joint is installed, play good sealing function.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or replacement without creative work is expected all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
