Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor auxiliary tooling, and in particular relates to a thyristor radiator installation tooling. Background Art

[0002] Thyristor, also known as silicon controlled rectifier, is a high-power electrical component. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power driver to control high-power equipment with low-power controls. It has been widely used in AC and DC motor speed control systems, power control systems and follow-up systems.

[0003] At present, due to the compact structure of thyristors, a large amount of heat is generated when the thyristors are working, and the heat accumulation will cause the temperature of the thyristors to rise, thus affecting their performance and life. Therefore, some high-power thyristors usually need to be used with a heat sink, and the coordinated installation of the thyristors and the heat sink usually requires multiple sets of bolts to penetrate the heat sinks clamped at both ends of the thyristors for fixing. During the installation process, due to the excessive number of components such as the heat sink, thyristors and bolts, the installation is more complicated and the assembly efficiency is low. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a thyristor heat sink installation tool for solving the problem of troublesome and low efficiency in assembling thyristors and heat sinks.

[0005] The utility model solves the above technical problems with the following technical solutions: a thyristor heat sink installation tool, comprising: a bottom plate;

[0006] At least two first position-limiting members are arranged on the bottom plate, a mounting area is formed between the two first position-limiting members, and the two first position-limiting members are respectively arranged to fit with two first side edges of the mounting area which are spaced apart from each other;

[0007] At least one second stopper is disposed on the bottom plate, and the second stopper is disposed in close contact with a second side edge of the installation area that is different from the first side edge thereof;

[0008] A plurality of positioning seats are arranged on the bottom plate in the installation area. The positioning seats are provided with embedded holes for matching with the screw heads, and the embedded holes are used to limit the rotation of the screws.

[0009] Compared with the prior art, the above technical solution has the following beneficial effects:

[0010] First, put the screw into the positioning seat. The embedded hole in the positioning seat can limit the rotation of the screw. Then, use the first limit piece and the second limit piece to form an installation area on the bottom plate. The two first limit pieces limit the left and right ends, and the second limit piece limits the top side of the installation area. No limit piece is set on the bottom side, so that the radiator can be easily placed in the installation area. When the radiator and thyristor are stacked in sequence, the first limit pieces and the second limit pieces on the three sides can play a limiting role from three sides, so that the holes on the radiator can be accurately aligned with the screw embedded in the positioning seat. After that, the stacked radiator and thyristor can be fastened by screws through nuts and other fasteners, thereby improving the overall efficiency.

[0011] Furthermore, a limiting groove having an outer contour not smaller than an outer contour of the installation area is provided on the bottom plate.

[0012] Furthermore, two side edges of the limiting groove are respectively matched and aligned with the second side edges of the installation area.

[0013] Furthermore, a connecting screw is provided at the bottom of the first limiting member, and the connecting screw is detachably connected to a first screw hole matched and opened in the bottom plate.

[0014] Furthermore, second screw holes matching the connecting screws are arranged at intervals on two outer sides of the first side of the installation area on the bottom plate, and the distance between the two second screw holes is not equal to the distance between the two first screw holes.

[0015] Furthermore, a plurality of positioning holes are provided on the bottom plate outside the installation area. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example

[0031] like Figure 1-2 As shown, the utility model provides a thyristor heat sink installation tool, which includes: a bottom plate, four first limit members, four second limit members and four positioning seats;

[0032] The first limiting member and the second limiting member are rod-shaped members, which are uniformly and vertically arranged on the bottom plate.

[0033] At least two first limit members are arranged on the base plate, and an installation area is formed between the two first limit members. In this embodiment, the installation area is shown by a dotted frame in the figure, and two first limit members are respectively arranged on both sides of the installation area. The two first limit members are respectively arranged on both sides to limit the end faces on both sides. Specifically, the two first limit members are respectively arranged to fit with the two first side edges spaced apart from each other in the installation area. Since the first limit members are fitted with the installation area, the installation area is consistent with the overall outer contour of the thyristor heat sink, so that after the heat sink and other parts are placed in the installation area, they can be exactly matched with the first limit members on both sides for limitation.

[0034] At least one second limiting member is arranged on the base plate. Specifically, in the present embodiment, four second limiting members are arranged. The second limiting members are arranged to fit the second side edge in the installation area which is different from the first side edge. From the figure, the second limiting member is also arranged to fit the installation area and is located on the second side edge where the upper side edge of the installation area is located. The first side edge is the left and right side edges of the installation area. In this way, the three side edges of the installation area all play a limiting role.

[0035] Four positioning seats are arranged on the base plate in the installation area, corresponding to four installation holes in the radiator, which are not shown in the hole position diagram. The positioning seat is provided with an embedding hole for matching with the screw head, and the embedding hole is used to limit the rotation of the screw. During installation, the head of the screw is inserted into the embedding hole, and the embedding hole limits the overall rotation of the screw. Then, the lower radiator, thyristor, upper radiator and other components are passed through the screw in turn. Multiple first limit members and second limit members can play a three-sided limiting role to ensure the overall consistency in the up and down directions.

[0036] In this embodiment, the lower heat sink, the thyristor and the upper heat sink which are sequentially stacked and installed are not shown in the figure.

[0037] Then, a mounting area is formed on the bottom plate by using the first limit piece and the second limit piece. The two first limit pieces limit the left and right ends, and the second limit piece limits the top side of the mounting area. No limit piece is set on the bottom side, so that the radiator can be easily placed in the mounting area. When the radiator and thyristor are stacked in sequence, the first limit pieces and the second limit pieces on the three sides can play a limiting role from three sides, so that the holes on the radiator can be accurately aligned with the screws embedded in the positioning seat. After that, the stacked radiator and thyristor can be fastened by screws through nuts and other fasteners, thereby improving the overall efficiency.

[0038] In this embodiment, a limiting groove with an outer contour not smaller than the outer contour of the installation area is opened on the bottom plate. The radiator can be embedded in the limiting groove when placed, and the radiator and other components can be positioned better and faster in conjunction with the limiting piece.

[0039] The two side edges of the limit groove are respectively matched and aligned with the second side edge of the installation area, so that the limit groove can quickly limit the upper and lower side edges, cooperate with the left and right side limitations of the limit member, and the vertical limitation when the limit member is stacked up and down, to achieve all-round limitation and rapid positioning.

[0040] To facilitate the adjustment of the first limit member, a connecting screw is provided at the bottom of the first limit member. The connecting screw is not shown in the figure. The connecting screw is detachably connected to the first screw hole matched in the base plate, so that the first limit member can be disassembled and adjusted.

[0041] Second screw holes matching the connecting screws are arranged on the outer sides of the first side of the installation area of ​​the bottom plate at intervals, and the spacing between the two second screw holes is not equal to the spacing between the two first screw holes. Since the spacing between the second screw holes is different from the spacing between the first screw holes, after the first limiting member is installed in the second screw hole, it can achieve limiting positioning of products of different sizes.

[0042] To facilitate the fixation of the bottom plate, a plurality of positioning holes are provided on the bottom plate outside the installation area. The positioning holes are located at the four corners of the bottom plate. The bottom plate can be fixed as a whole on a target position such as a table top through the positioning holes.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
