In the utility model, the software pad is set in described groove.
In the utility model, each water caltrop of described terminal box arranges respectively arc transition.
A kind of fieldbus signal distributor of the present utility model, compared with prior art, by signal distributor is arranged in terminal box, play the effect of protection to signal distributor; The upper cover of terminal box and lower cover be by bolt combination, play easy for installation, well-set effect, simple in structure, very practical, realize the purpose of this utility model.
The accompanying drawing explanation
Fig. 1 structural representation of the present utility model;
The structural representation of Fig. 2 lower cover;
The structural representation of Fig. 3 upper cover.
Wherein: 1, signal distributor; 2, terminal box; 21, incoming line; 22, line outlet; 23, branch line mouth; 24, upper cover; 241, groove; 25, lower cover; 251, fin.
Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment, the utility model is further described.
Embodiment
As Fig. 1 is structural representation of the present utility model; Fig. 2 is the structural representation of lower cover; Fig. 3 is the structural representation of upper cover.
A kind of fieldbus signal distributor, comprise signal distributor 1, and signal distributor 1 is arranged in terminal box 2, and incoming line 21, line outlet 22 and branch line mouth 23 are set respectively on terminal box 2; Signal distributor 1 is played to the effect of protection.
Terminal box 2 be shaped as cuboid, for the utility model execution mode preferably, can reach result of use preferably; Certainly the utility model terminal box can also have various ways, as square, rhombogen, centrum etc., makes the outward appearance kind variation of product.
The quantity of branch line mouth 23 is at least 1; Can produce the distributor that has varying number branch line mouth 23, according to the device requirement selectivity, buy, use, reach the effect of making the best use of everything.
Incoming line 21 and line outlet 22 are separately positioned on two short sides of cuboid terminal box 2, branch line mouth 23 is arranged on the long side of cuboid terminal box 2, for the utility model execution mode preferably, because the area on long limit, both sides is larger, the branch line mouth 23 of greater number just can be set.
Terminal box 2 comprises upper cover 24 and lower cover 25, and upper cover 24 covers on lower cover 25, and upper cover 24 and lower cover 25 are bolted, and is the utility model execution mode preferably; Certainly, in alternative, the utility model also can be selected the mode of the flexible connections such as hinge.
My 30mm-60mm of the thickness of lower cover 25, the thickness of upper cover 24 is 1mm-3mm; Within this scope, can reach and be used in conjunction with preferably effect.
