Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to an output line mounting structure for a power control black box. Background Technology

[0002] In existing control box structures (such as power control black box products), output wires are typically passed directly through through-holes in the box wall or simply snapped into thin-walled slots for fixation. Due to space constraints in the box structure, its inner wall is often thin and has limited strength, resulting in insufficient radial constraint on the output wires. During equipment handling, cable laying, or daily use, the output wires are easily pulled out of the box due to external pulling, which can even lead to loosening or damage to the terminals, seriously affecting the reliability of electrical connections and product lifespan. In addition, frequent plugging and unplugging or vibration environments can further aggravate wear between the wires and the thin-walled structure, posing a significant risk of connection failure. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide an output line mounting structure for a power control black box.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an output line mounting structure for a power control black box, comprising a control box and a plurality of control output lines at least partially confined within the control box. The control box includes a box body and a box cover; the box body is provided with a plurality of receiving slots for accommodating the control output lines; a limiting seat is connected to the control output lines, the limiting seat can overlap within the receiving slots, and the limiting seat at least partially abuts against the inner sidewall of the box body; a limiting groove is provided on the upper surface of the limiting seat; a limiting plate is provided on the inner side of the box cover, and when the box cover and box body are closed, the limiting plate is inserted into the limiting groove to restrict the control output lines from being pulled out of the box body.

[0005] As a preferred embodiment of this utility model, the box body is provided with a support frame corresponding to the position of the receiving groove; the limiting seat is mounted on the support frame and is inserted into the support frame.

[0006] As a preferred embodiment of this utility model, the support frame includes two symmetrically arranged support plates; the support plate has a positioning notch on the side facing the box; the limiting seat has symmetrically arranged limiting holes that are inserted and cooperate with the support plate; a part of the limiting seat is embedded in the positioning notch.

[0007] As a preferred embodiment of this utility model, the limiting seat is provided with a blocking plate on the side facing away from the receiving groove; when the box cover and the box body are closed, the limiting plate abuts against the outer wall of the blocking plate.

[0008] As a preferred technical solution of this utility model, the side wall of the limiting plate is provided with a plurality of reinforcing ribs at intervals along its length direction, and the reinforcing ribs are connected to the inner wall of the box cover.

[0014] 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.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-7 The diagram illustrates an output cable mounting structure for a power control black box, comprising a control box 1 and a plurality of control output cables 2 at least partially confined within the control box 1. The control box 1 includes a box body 3 and a box cover 4. The box body 3 is provided with a plurality of receiving slots 5 for accommodating the control output cables 2. A limiting seat 6 is connected to the control output cable 2, and the limiting seat 6 can overlap within the receiving slots 5, with at least a portion of the limiting seat 6 abutting against the inner sidewall of the box body 3. A limiting groove 7 is provided on the upper surface of the limiting seat 6. A limiting plate 8 is provided on the inner side of the box cover 4. When the box cover 4 and the box body 3 are closed, the limiting plate 8 is inserted into the limiting groove 7 to restrict the control output cables 2 from being pulled out of the box body 3. In this embodiment, the receiving slots 5 are provided with an open structure above them to facilitate the installation of the control box 1 output cables. In this embodiment, the small black box is a standard black cuboid, consisting of a control box 1 and a power supply box 17. The size of the power control small black box is usually within the range of (length ≤ 300mm, width ≤ 150mm, height ≤ 50mm), which is a compact design. The specific external dimensions of this application are 283.5mm (length) x 135mm (width) x 40mm (height). Within this range and compared with similar power control small black boxes, it has a higher space utilization rate and is more compact.

[0017] The overlapping fit between the limiting seat 6 and the receiving groove 5 of the box 3, along with the abutting structure between the limiting seat 6 and the inner wall of the box 3, fundamentally restricts the outward displacement of the output line, significantly enhancing the tensile strength of the cable fixation. Even in the thin-walled box 3 structure, it effectively avoids problems such as wire loosening, terminal loosening, or even damage caused by external pulling. Specifically, axial positioning is achieved through the overlapping fit between the limiting seat 6 and the receiving groove 5; the limiting plate 8 on the box cover 4 is precisely inserted into the limiting groove 7 of the limiting seat 6 when the box cover 4 is closed. This double fixing mechanism effectively enhances the tensile strength and connection reliability of the output line within the thin-walled box 3, completely solving the problem of the output line being easily pulled out or loosened in traditional structures.

[0018] The main improvement of this application lies in the mechanical fixing method of the output line mounting structure of the control box 1, specifically involving the physical mating structure between the box body 3, the limiting seat 6, and the box cover 4 to restrict the movement of the control output line 2. This solution, through the synergistic action of the receiving groove 5, the limiting seat 6, and the limiting plate 8, effectively solves the mechanical connection problem of the output line being easily pulled out or loosened within the thin-walled box body 3. As for the control method of the control module on the controlled device, and the circuit connection relationship between the power module, the control output line 2, and the controller, these are all prior art in this field, and their specific implementation methods are not the subject of this application.

[0019] The box body 3 is provided with a support frame 9 corresponding to the position of the receiving groove 5; the limiting seat 6 is mounted on the support frame 9 and is inserted into the support frame 9.

[0020] The support frame 9 includes two symmetrically arranged support plates 10; the support plate 10 has a positioning notch 11 on the side facing the box 3; the limiting seat 6 has symmetrically arranged limiting holes 12 that are inserted and cooperate with the support plate 10; a part of the structure of the limiting seat 6 is embedded in the positioning notch 11.

[0021] The limiting seat 6 has a baffle plate 13 on the side facing away from the receiving groove 5; when the box cover 4 and the box body 3 are closed, the limiting plate 8 abuts against the outer wall of the baffle plate 13.

[0022] The sidewall of the limiting plate 8 is provided with a number of reinforcing ribs 14 at intervals along its length. The reinforcing ribs 14 are connected to the inner wall of the box cover 4 to improve the strength of the limiting plate 8 and prevent the limiting plate 8 from deforming when the control output line 2 is pulled.

[0023] The side wall of the lid 4 is provided with several locking blocks 15; the inner wall of the box body 3 is provided with several locking grooves 16 that engage with the locking blocks 15, or magnetic or screw connections can be used.
