Description

Technical Field

[0001] The utility model relates to the field of supporting facilities for high and low voltage electrical appliances, in particular to a power distribution cabinet. Background Art

[0002] The interior of the distribution cabinet is generally used to install high and low voltage electrical components, and some control components (switches) or / and indicating components (indicator lights, display screens) are often installed on the cabinet door. Therefore, the corresponding connecting wires of the control components (switches) or / and indicating components (indicator lights, display screens) on the cabinet door will be connected to the terminal block in the distribution cabinet. Since the cabinet door is a movable part, the corresponding connecting wires will move together when it is opened and closed, which may easily cause scratches and breakage. The traditional wiring method is often to organize the wire harness on the cabinet door and then wrap it with a spiral cable sheath, and then lead it into the distribution cabinet. This means that when the number of accessories or cables needs to be increased or decreased in the future, the spiral cable sheath needs to be disassembled and rewound, which is extremely time-consuming and labor-intensive. Utility Model Content

[0009] In the above structure, the structure of the traditional cabinet opening position is effectively utilized, and double fixation is achieved by fixing the fixing plate while using the anti-slip plate and the anti-slip hook to buckle with the end of the retaining edge, making the fixation of the wiring tube more stable and reliable.

[0010] The utility model is further configured such that when the first half pipe and the second half pipe are buckled together, the lock is oriented toward the rear wall of the cabinet; and the wire outlet groove is located on the first half pipe.

[0011] In the above structure, the outlet groove can be oriented toward the rear wall of the cabinet, which is more convenient for wiring.

[0012] The utility model is further configured to include an annular anti-scratch sleeve, which includes a plug-in tube and an anti-scratch edge located at one end of the plug-in tube, and the outer diameter of the anti-scratch edge is larger than the outer diameter of the plug-in tube; when the first half tube and the second half tube are buckled together, the plug-in tube is inserted into the end position of the wiring tube and the anti-scratch edge is against the end face of the wiring tube.

[0013] In the above structure, the cabinet door will drive the wire harness to move when it is opened and closed. Placing the annular anti-scratch sleeve at the end of the wiring tube can effectively reduce friction.

[0014] The utility model is further configured that the plug-in tube and the anti-scratch edge of the annular anti-scratch sleeve are provided with expansion seams.

[0015] In the above structure, the wiring harness can be taken out from the annular anti-scratch sleeve by stretching the expansion seam. When the annular anti-scratch sleeve is placed in the wiring tube, the expansion seam is closed or rotated toward the rear wall of the cabinet to avoid scratching between the expansion seam and the wiring harness.

[0016] The utility model is further configured that the annular anti-scratch sleeve is made of polytetrafluoroethylene.

[0017] In the above structure, the polytetrafluoroethylene material has self-lubricating properties, thereby reducing friction on the wiring harness.

[0018] The utility model is further configured such that the axis of the wiring tube is parallel to the rotation axis of the cabinet door.

[0019] In the above structure, the pulling of the wire harness when the cabinet door is opened and closed is reduced as much as possible.

[0020] The utility model is further configured such that the first half tube and the second half tube are made of plastic material, and the two are integrally formed and connected.

[0021] In the above structure, the first half tube and the second half tube are formed by injection molding, extrusion and stretching (the same as the plastic tube forming method), and after forming, the wire grooves are cut out by stamping and divided into sections; the hinge between the two is relatively weak, so that the connection is achieved while utilizing the material's own deformation to hinge.

[0022] The beneficial effects of the utility model are as follows: a wiring tube is arranged on the retaining edge of the side where the cabinet body and the cabinet door are hinged, and when the wiring harness on the cabinet door needs to be connected to the cabinet body, the wiring harness only needs to be arranged and placed in the first half tube (placed from the end of the wiring tube), and then fixed by snapping the second half tube; for the wiring of the wiring harness at different positions in the cabinet body, wire outlet grooves are arranged at intervals along the length direction of the wiring tube, so that the wiring harness located in the wiring tube can be passed out at a suitable position, which is conducive to wiring; at the same time, when the wiring harness is increased or decreased due to the increase or decrease of electrical components in the later stage, it can be quickly installed and removed, eliminating the disadvantage of the troublesome disassembly and assembly of the existing spiral cable sheath; because the wiring tube is located on the side where the cabinet body and the cabinet door are hinged, the pulling and deformation of the wiring harness when the cabinet door is opened and closed can also be minimized.
