Abstract

The utility model provides an internal shield type wireway, wherein, a wireway structure the inside of which is hollow is formed by a wireway body (3) and a wireway cover (1), and a shielding layer is also arranged inside the wireway body. The internal shield type wireway effectively solves the problem of interference due to arrangement of various electric appliance wires inside the same wireway through independent arrangement of the shielding layer inside the wireway, thereby the high anti-interference requirement of special lines is met.

Description

A kind of internally shielded wiring duct

Technical field

The utility model belongs to industrial electrical control cubicles accessory field, particularly relates to a kind of wiring duct structure.

Technical background

The employed in the market various terminals of industrial wire casing are drawn from the wire hole of industrial wire casing both sides, do not have thing at interval in the middle of the terminals of access controller, wire casing, for the frequent control panel of work, the phenomenon that terminals sparkle can occur.Existing various electrical equipment all are contained in a wire casing the inside with line can produce interference, and makes troubles for the maintenance of circuit.Day by day do not satisfy user's diversification user demand, particularly resist interference requirement than higher device line.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of by shielding construction, solves effectively that industrial electrical control cubicles terminals sparkle and the potential safety hazard that exists, thereby improves the performance of safety utilization of electric power.

In order to realize the foregoing invention purpose, the technical scheme of employing is as follows:

A kind of internally shielded wiring duct, the trough body structure of the inner hollow of forming by wire casing main body and wire casing lid, described cell body inside also is provided with screen.

The utility model, is separated the electric wire of wiring duct inside as the same wiring duct that works alone at the inner screen that is provided with of wire casing, effectively prevents because of potential safety hazards such as sparkling of too much causing of electric wire.

In the technique scheme, described screen is the airtight trough body structure of hollow.

Wire casing lid described in the utility model is connected with the wire casing subject activity, is convenient to install.

Because main feature of the present utility model is to be provided with in the wiring duct independently wiring duct, for simple in structure, and the purpose of being convenient to produce, described screen is made up of shielding riser that is arranged at the wire casing body interior and shielding trench lid, and described shielding riser and shielding trench lid interconnect and be obturator.

Described shielding trench lid also adopts movable connection structure with the shielding riser.

So far, a preferred version of the present utility model is to be made up of wire casing lid, wire casing main body, shielding riser, shielding trench lid, described wire casing main body and wire casing lid fasten mutually and are the closed cell body structure, described shielding riser is the structure of holding up that is set in parallel in the wire casing body interior, described shielding trench lid is interlocked with the shielding riser, becomes screen.

The utility model effectively solves various electrical equipment and all is contained in the wire casing that a wire casing the inside can produce interference phenomenon with line by in wiring duct inside independently screen being set, and satisfies special circuit in anti-interference purpose of having relatively high expectations thereby reach.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a user mode schematic diagram of the present utility model;

Fig. 3 is an assembling schematic diagram of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Structural representation of the present utility model as shown in Figure 1, form by wire casing enclosing cover 1, wire casing main body 3, shielding riser 6, shielding trench lid 2, described wire casing main body 3 and wire casing enclosing cover 1 fasten mutually and are the closed cell body structure, described shielding riser 6 is for being set in parallel in the structure of holding up of wire casing main body 3 inside, described shielding trench lid 2 is interlocked with the shielding riser, becomes screen.

User mode schematic diagram of the present utility model as shown in Figure 2, wire casing enclosing cover 1 and wire casing main body 3 are buckled into the common electrical wire casing, shelve inside does not need the electric wire 5 that shields, and shielding riser 6 and the shielding trench lid 2 of being located at wire casing main body 3 inside fasten mutually, the shielding wire casing that becomes can work independently, and described screen of the present utility model need the electric wire 4 of shielding just to be shelved on screen inside, make the utility model simple in structure, convenient and practical.

Assembling schematic diagram of the present utility model as shown in Figure 3, when the construction and installation circuit, pack the circuit that requires to carry out shielding processing into wiring duct inside independently in the wiring duct, load onto the wiring duct lid and get final product, the circuit that does not need to shield is then packed in the wire casing main body, buckles the wire casing enclosing cover and then can.
