Description

Technical Field

[0001] This utility model relates to the field of electrical control box manufacturing technology, and in particular to an electrical control box. Background Technology

[0002] As a crucial component housing and protecting core circuit boards, relays, contactors, terminals, and other electrical elements, the performance of the electrical control box directly affects the stability, safety, and reliability of the entire electrical system. With the rapid development of electronic technology and increasingly higher levels of integration, the structural design of electrical control boxes faces even more severe challenges. (See attached diagram) Figure 1 In existing electrical control boxes, the box body is fixed to other equipment with screws inside the box, and the box cover is then fixed to the box body with screws. The box cover and box body form a sealed chamber, making it difficult for the heat generated by the internal components to dissipate, resulting in low heat dissipation efficiency. Secondly, the cable outlet uses a simple rubber ring seal, which is prone to aging and failure after long-term use. The seal at the screw fixing point also lacks a reliable design. Under harsh working conditions (such as dusty and humid environments), dust and moisture can easily enter the box, causing short circuits, corrosion, or a decrease in insulation performance. Utility Model Content

[0004] This utility model provides an electrical control box, including a box body with a box opening, a plurality of card plates fixed inside the box body, the plurality of card plates forming a slot adapted to an electrical control component, the electrical control component being connected to a connector on the box wall of the box body, a heat sink being connected to the electrical control component facing the box opening, a sealant being poured inside the box body, the heat sink being exposed outside the sealant, a step being provided on the outer side of the box body, and screw holes being provided on the step.

[0005] Preferably, the electronic control element has two mounting plates on the side closest to the connector, and one mounting plate on each of the remaining three sides.

[0006] Preferably, the card plate is vertically disposed on the bottom of the box body, and the card slot and heat sink are respectively disposed on both sides of the electronic control component.

[0007] Preferably, a mounting hole is provided on one side of the housing, and the connector is disposed in the mounting hole. The connector is connected to the electronic control element on the card slot through a connecting line.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] See attached document Figure 2 and attached Figure 5 This utility model provides an electrical control box, including a box body 1 with a box opening. Multiple retaining plates 2 are fixed inside the box body 1, forming a slot 100 adapted to an electrical control element 6. The electrical control element 6 is connected to a connector 3 on the box wall of the box body 1. A heat sink 4 is connected to the electrical control element 6 facing the box opening. Sealant 5 is poured inside the box body 1, with the heat sink 4 protruding outside the sealant 5. A step 200 is provided on the outer side of the box body 1, with screw holes 11 on the step 200. This utility model eliminates the need for a sealed box lid. The electrical control element 6 is secured within the slot 100. After the electrical control element 6 is connected to the connector 3, the sealant 5 poured inside the box body 1 provides waterproofing and vibration protection. The heat sink 4 exposed outside the sealant 5 can quickly dissipate the heat generated by the electrical control element 6 to the external environment, resulting in high heat dissipation efficiency. The screw holes 11 on the outside of the box body 1 do not affect the sealing performance of the sealant 5, facilitating installation and subsequent maintenance. Third, step 200 can reduce the volume of box 1 and reduce the amount of material used.

[0020] Specifically, connector 3 serves as the connection point for the entire control box, connecting to external electrical wiring.

[0021] In another embodiment of this utility model: two retaining plates 2 are distributed on the side of the electronic control element 6 near the connector 3, and one retaining plate 2 is distributed on each of the remaining three sides. By setting the retaining plates 2 on the box body 1 to form a retaining groove 100, and then positioning the electronic control element 6 through the retaining groove 100, the overall structure of the box body 1 is simple and easy to manufacture.

This structural design effectively prevents the connector 3 from being ejected from the housing 1. In another embodiment of this utility model, the connector 3 has a first groove 32 at one end inside the box. This structural design allows the sealant 5 to interlock with the connector 3, effectively preventing the connector 3 from loosening even after multiple insertions and removals.

[0026] As another embodiment of this utility model: refer to the appendix Figure 4 The mounting hole 12 includes a square hole 121 and a trapezoidal hole 122 connected to the square hole 121.

[0027] As another embodiment of this utility model: the screw hole 11 is a countersunk hole.

[0028] As another embodiment of this utility model: the upper end of the heat sink 4 is flush with the opening of the box body 1.
