Description

Technical Field

[0001] This utility model is a device for connecting a power distribution box / cabinet to a cable tray, belonging to the technical field of power distribution box / cabinet. Background Technology

[0002] The connection device between the distribution box / cabinet and the cable tray is mainly used in power systems to ensure that wires and cables can be safely and orderly introduced from the cable tray into the distribution box / cabinet, thereby ensuring the normal operation of the circuit and the convenience of maintenance. Its core function is to provide a reliable physical connection path and protect the internal wiring from the influence of the external environment.

[0003] Publication number CN219351200U mentions a connection structure between a cable tray and a distribution box / cabinet. In this device, the main body of the connector and the wing are integrally molded with a smooth transition, and are connected to the cable tray and the box shell by bolts. The installation is stable and does not deform or shift, which can effectively prevent the insulation layer from being damaged due to the cable scraping against the right angle and edge of the box shell and cable tray during the laying process. However, once this device is installed and fixed by bolts, the installation time is relatively long, and it is especially unsuitable for tightening bolts in situations where space is limited. There is an urgent need for a connection device between the distribution box / cabinet and the cable tray to solve the above-mentioned problems. Utility Model Content

Ferrite magnet posts are fixed at the front and rear sides of the lower end of the snap-fit ​​handle. An insulating inner frame is fixed inside the fixed outer frame. A first rubber sealing frame is fixed to the left edge of the insulating inner frame with epoxy resin. A positioning groove is provided inside the insulating inner frame. A plug-in frame is fixed inside the outer protective frame through a connecting frame. A cable tray inner frame is installed through the plug-in frame. Ferrite magnet blocks are fixed around the right side of the outer protective frame. A second rubber sealing frame is fixed to the right edge of the plug-in frame. Magnet post slots are provided at the front and rear positions of the upper right side of the plug-in frame.

[0006] Furthermore, the right end of the outer protective frame abuts against the fixed outer frame, and the inner frame of the wire trough is inserted into the insulating inner frame.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figs. 1-3 This utility model provides a technical solution: a connection device between a distribution box cabinet and a cable tray, including a distribution box cabinet body 1 and an outer protective frame 11. A welding frame 2 is welded through the upper left side of the distribution box cabinet body 1. A fixed outer frame 3 is fixed through the welding frame 2. An inclined plate 4 is fixed at the upper end of the fixed outer frame 3. A snap-fit ​​handle 5 passes through between the inclined plate 4 and the upper end of the fixed outer frame 3. Ferrite magnet posts 6 are fixed at the front and rear sides of the lower end of the snap-fit ​​handle 5. An insulating inner frame 8 is fixed inside the fixed outer frame 3. A first rubber sealing frame is fixed to the left edge of the insulating inner frame 8 by epoxy resin. 9. The inner insulating frame 8 has a positioning groove 10 inside. The outer protective frame 11 has a plug-in frame 13 fixed inside through the connecting frame 17. The plug-in frame 13 has a wire groove inner frame 16 installed through it. Ferrite magnet blocks 12 are fixed around the right end of the outer protective frame 11. The right edge of the plug-in frame 13 has a second rubber sealing frame 14 fixed. Magnet post slots 15 are opened at the front and rear positions of the upper right side of the plug-in frame 13. This design solves the problem that the original device takes a long time to install once it is installed and fixed by one-piece molding and bolts, and is especially unsuitable for tightening bolts in space-constrained situations.

[0019] As the first embodiment of this utility model: the right end of the outer protective frame 11 abuts against the fixed outer frame 3, and the inner frame 16 of the wire trough is inserted into the insulating inner frame 8. By adding the right end of the outer protective frame 11 abutting against the fixed outer frame 3 and inserting the inner frame 16 of the wire trough into the insulating inner frame 8, the inner frame 16 of the wire trough can be connected to the inside of the main body 1 of the distribution box cabinet, thereby facilitating the insertion of wires and cables into the main body 1 of the distribution box cabinet.

[0020] Multiple positioning holes 7 are provided on the left end of the fixed outer frame 3. Multiple ferrite magnet blocks 12 are inserted into the multiple positioning holes 7 by magnetic attraction. Two ferrite magnet pillars 6 are inserted into the two magnet pillar slots 15 by magnetic attraction. By adding multiple ferrite magnet blocks 12 and inserting them into the multiple positioning holes 7 by magnetic attraction, it is not easy for the right end of the outer protective frame 11 to abut against the fixed outer frame 3. The two ferrite magnet pillars 6 are inserted into the two magnet pillar slots 15 by magnetic attraction, which can realize the fixation between the plug-in frame 13 and the fixed outer frame 3.

[0021] The first rubber sealing frame 9 is fully inserted into the gap between the right side of the connection between the plug-in frame 13 and the inner frame 16 of the wire trough, and the second rubber sealing frame 14 is fully inserted into the gap between the left side of the connection between the fixed outer frame 3 and the insulating inner frame 8. This double sealing effectively prevents moisture and dust from entering through the gaps. The lower end of the main body 1 of the distribution cabinet is equipped with support legs, and the upper end of the main body 1 is fitted with an inclined cover. Honeycomb ventilation holes are located on the lower left side of the main body 1.

[0022] As a second embodiment of this utility model: First, slightly lift the latch handle 5, then align the outer protective frame 11 with the left side of the fixed outer frame 3 and insert it. During this process, multiple ferrite magnet blocks 12 are inserted into multiple positioning holes 7 by magnetic attraction until the right end of the outer protective frame 11 abuts against the fixed outer frame 3. At this time, the inner frame 16 of the wire trough is inserted into the insulating inner frame 8, the first rubber sealing frame 9 is completely inserted into the gap between the right side of the insertion frame 13 and the inner frame 16 of the wire trough, and the second rubber sealing frame 14 is completely inserted into the gap between the left side of the fixed outer frame 3 and the insulating inner frame 8. Then push down the latch handle 5 so that the two ferrite magnet pillars 6 are inserted into the two magnet pillar slots 15 by magnetic attraction, and the overall installation is completed.
