Abstract
The utility model provides a high-protective anti-interference PLC outer shell, which comprises an upper cover and a pedestal, and is characterized in that: an upper end surface of the pedestal is provided with a circle of sealing groove; the lower end surface of the upper cover is provided with a circle of sealing protrusion fitting with the sealing groove in mounting; the sealing groove and the sealing protrusion are sealed through a conductive rubber sealing ring; communication interfaces on the pedestal are sealed through conductive rubber; and the upper cover and the pedestal are manufactured by using conductive materials. By adopting the technical scheme, since the sealing groove and the protrusion are arranged and are sealed through the conductive rubber, the waterproof function is achieved, and the electromagnetic interference can be shielded inside the shell body, thereby achieving the anti-electromagnetic interference effect.
Description
Technical field
The utility model belongs to a kind of PLC shell, specifically belongs to the jamproof PLC shell of a kind of high protection.
Background technology
At present PLC is in utilization widely and each electric field, but PLC itself is an integrated circuit, promptly has a shell usually its circuit board is protected; But PLC shell at present on the market all just plays and prevents that components and parts are exposed in the air in the PLC, does not have the effect of an anti-electromagnetic interference, simultaneously; If PLC will be applied to a humidity or have in the environment of big water gaging; Its water resistance also can not get guaranteeing, salt fog, mould environment.
Summary of the invention
The utility model then provides a kind of simple in structure in order to solve the technical problem of mentioning in the background technology, effectively the PLC shell of waterproof, anti-electromagnetic interference.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The jamproof PLC shell of a kind of high protection; Comprise loam cake and base; It is characterized in that: said base upper surface is provided with a circle seal groove, and the loam cake lower surface is provided with the seal convexity of a circle and the suitable installation of seal groove, seals through the conductive rubber sealing ring between said seal groove and the seal convexity.
Each communication interface place on the said base is through the conductive rubber sealing.
But said loam cake and base all adopt electric conducting material to process.
After adopting above technical scheme: owing to be provided with seal groove and convexity, and seal through conductive rubber, then when playing waterproof, can be with electromagnetic interference shield in enclosure interior, thus played the effect of anti-electromagnetic interference.
Description of drawings
Fig. 1 is the structural representation of the utility model loam cake;
Fig. 2 is the structural representation of the utility model base;
Fig. 3 is the assembly structure sketch map of the utility model.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the jamproof PLC shell of a kind of high protection comprises loam cake 1 and base 2; Base 2 upper surfaces are provided with a circle seal groove 3, and loam cake 1 lower surface is provided with the seal convexity 4 of a circle and seal groove 3 suitable installations, seal through conductive rubber sealing ring 5 between seal groove 3 and the seal convexity 4; To be exactly that a circle conductive rubber ring is placed in the seal groove 3 particularly, cover loam cake 1 then after, the seal convexity 4 of loam cake 1 and rubber seal 5 seals and contacts; Thereby reach the effect of sealing; Each communication interface 6 places on the base 2 are through conductive rubber 7 sealings, but loam cake 1 all adopts electric conducting material to process with base 2, and are one-body molded; Base 2 bottoms are provided with some heat sink strips 8, are used for the PLC heat radiation.
To further being explained as follows of the utility model technical scheme:
1) except outside the structure above-mentioned; Is to exchange each other for seal groove 3 with protruding 4 settings with respect to loam cake 1 and base 2; Be that base 2 upper surfaces are provided with a circle convexity; Loam cake 1 lower surface is provided with the seal groove of a circle and protruding suitable installation, and through the conductive rubber sealing, such structure is also in the protection range of the utility model between seal groove and the convexity.
2) simultaneously except being provided with the conductive seal circle between seal groove 3 and protruding 4; Each communication interface 6 places on the base 2 are through outside the conductive rubber sealing; This enclosure all needs conductive rubber to seal with extraneous contacted port, to guarantee its water proofing property and anti-electromagnetic interference property.
3) when each PORT COM of the utility model does not use, need to overlap the cover that powers on, to guarantee water proofing property and anti-electromagnetic interference property.
The beneficial effect of the utility model: owing to be provided with seal groove and convexity, and seal through conductive rubber, then when playing waterproof, can be with electromagnetic interference shield in enclosure interior, thus played the effect of anti-electromagnetic interference.
