A thyristor harness mounting device

Abstract

This utility model relates to the field of thyristor technology and discloses a thyristor wire harness installation device, including a base plate. Three pads and two guide supports are fixedly installed on the bottom surface of the base plate by bolts. Two side plates are fixedly installed on both sides of the upper surface of the base plate by bolts. An assembly plate is fixedly installed on the upper surface of the base plate. The outer surfaces of both sides of the assembly plate engage with the slots on the rear sides of the two side plates. The device uses a rotating connection structure of a pressure roller and a quick clamp, where a fixed base and a connecting base cooperate. The quick clamp presses down to vertically press the wire harness terminals in the plug-in fixing block assembly into the thyristor insert. Because the clamping force after the connector and insert are pressed in is greater than the clamping force of the spring positioning post, when the quick clamp is lifted, the terminals can detach from the plug-in fixing block and firmly connect to the insert, achieving reliable installation of the wire harness. This avoids damage to terminals or inserts due to improper manual force control, improving installation efficiency and the reliability of thyristor use.

Description

Technical Field

[0001] This utility model relates to the field of thyristor technology, and more specifically, to a thyristor wiring harness installation device. Background Technology

[0002] A thyristor is a high-power semiconductor device with functions such as controlled rectification, inversion, and voltage regulation. It is widely used in power electronic circuits, often as a switch and voltage regulator to achieve efficient conversion and control of electrical energy. In practical applications, in order to build a complete circuit connection and ensure its normal functioning, a wiring harness needs to be installed on the thyristor to realize signal transmission and power supply.

[0003] When using thyristors, we need to install wiring harnesses on them. A common method is to use pliers to clamp the terminals and then install them onto the thyristor terminals. This method has many problems. First, when using pliers to clamp, it is easy to damage the terminals due to the difficulty in controlling the force manually. Second, when installing onto the thyristor's connector, the non-vertical downward pressure causes tilting during pressing, which damages the connector. Ultimately, the damage to the connector renders the thyristor unusable. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a thyristor wiring harness installation device, which aims to solve the problems in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a thyristor harness installation device, comprising a base plate, wherein three pads and two guide supports are fixedly installed on the bottom surface of the base plate by bolts, two side plates are fixedly installed on both sides of the upper surface of the base plate by bolts, and an assembly plate is fixedly installed on the upper surface of the base plate, wherein the outer surfaces of both sides of the assembly plate are engaged with the slots on the rear sides of the two side plates, and the outer surface of each side plate is threadedly connected to the inner wall of the assembly plate by bolts.

[0008] The present invention is further configured such that a positioning plate is fixedly installed on the upper surface of the base plate by bolts, and a symmetrical positioning pin is fixedly installed in the middle of the positioning plate.

[0009] The present invention is further configured such that optical axis seats are fixedly installed on the side of the two side plates that are close to each other by bolts, and guide shafts are fixedly installed inside each optical axis seat and inside the guide support located directly below the optical axis seat. The outer surfaces of the two guide shafts are slidably connected to a mounting plate, and linear bearings are fixedly installed on the inner wall of the mounting plate. The inner ring of each linear bearing is fixedly connected to the outer surface of the guide shaft.

[0010] The present invention is further configured such that a fixing seat is fixedly installed on the front side of the mounting plate by bolts, a connecting seat is fixedly installed on the upper surface of the mounting plate by bolts, a pressure roller is fixedly installed on the upper surface of the connecting seat, a quick clamp is rotatably connected to the top end of the pressure roller, and the top end of the quick clamp is rotatably connected to the inner wall of one end of the fixing seat.

[0011] The present invention is further configured such that a plug-in fixing block assembly is provided below the mounting plate, and the upper surface of the plug-in fixing block assembly is fixedly connected to the bottom surface of the mounting plate.

[0012] The present invention is further configured such that mounting holes are provided on both sides of the plug-in fixing block assembly, and a spring positioning post is fixedly installed on the inner wall of each mounting hole.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The positioning plate and positioning pin installed on the base plate can accurately position the installation position of the thyristor, ensuring its accurate placement. Together with the optical axis seat and guide shaft fixed on the side plate, the mounting plate slides stably on the guide shaft through the linear bearing, realizing the vertical pressing action of the plug-in fixing block assembly, avoiding the problem of tilting during manual installation.

[0016] 2. By cooperating with the fixing seat on the assembly plate and the connecting seat on the mounting plate, and utilizing the rotating connection structure of the pressure roller and quick clamp, the wire harness terminals in the plug-in fixing block assembly can be vertically pressed into the thyristor insert by pressing down with the quick clamp. Since the clamping force after the connector and insert are pressed in is greater than the clamping force of the spring positioning post, when the quick clamp is lifted, the terminal can be separated from the plug-in fixing block and firmly connected to the insert, realizing reliable installation of the wire harness, avoiding damage to the terminal or insert due to improper manual force control, improving installation efficiency and the reliability of thyristor use.

[0025] Please see Figures 1-4 The system includes a base plate 1. Three pads 15 and two guide supports 16 are fixedly installed on the bottom surface of the base plate 1 by bolts. Two side plates 6 are fixedly installed on both sides of the upper surface of the base plate 1 by bolts. An assembly plate 12 is fixedly installed on the upper surface of the base plate 1. The outer surfaces of both sides of the assembly plate 12 are engaged with the grooves on the rear sides of the two side plates 6. The outer surface of each side plate 6 is threadedly connected to the inner wall of the assembly plate 12 by bolts.

[0026] Specifically, three pads 15 are fixed to the bottom surface of the base plate 1 with bolts to support the device and keep it stable. Two guide supports 16 are fixed to the bottom surface of the base plate 1 to provide an installation base for the guide shaft 8. Two side plates 6 are fixed to the two sides of the upper surface of the base plate 1 with bolts to form the side support structure of the device. The assembly plate 12 is engaged with the rear groove of the side plate 6 and then fixed with bolts to achieve a stable connection between the assembly plate 12 and the side plate 6, thus forming the main frame of the device.

[0027] Please see Figures 1-4 A positioning plate 2 is fixedly installed on the upper surface of the base plate 1 by bolts, and a symmetrical positioning pin 3 is fixedly installed in the middle of the positioning plate 2.

[0028] Specifically, the positioning plate 2 is fixed to the upper surface of the base plate 1 with bolts, and the positioning pin 3 is fixed in the middle of the positioning plate 2. When in use, the thyristor is placed on the positioning plate 2, and the positioning pin 3 is inserted into the positioning hole of the thyristor to achieve precise positioning of the thyristor and ensure that its position is fixed when installing the wire harness, avoiding the problem of inaccurate installation due to position offset.

[0029] Please see Figures 1-4 On the side of the two side plates 6 that are close to each other, optical axis seats 9 are fixedly installed by bolts. Guide shafts 8 are fixedly installed inside each optical axis seat 9 and inside the guide support 16 located directly below the optical axis seat 9. The outer surfaces of the two guide shafts 8 are slidably connected to the mounting plate 5. Linear bearings 7 are fixedly installed on the inner wall of the mounting plate 5. The inner ring of each linear bearing 7 is fixedly connected to the outer surface of the guide shaft 8.

[0030] Specifically, the optical axis seat 9 is fixed to the inside of the side plate 6 by bolts, the guide shaft 8 passes through the optical axis seat 9 and the guide support 16 below and is fixed, and the mounting plate 5 is sleeved on the guide shaft 8 by a linear bearing 7. When a force is applied to the mounting plate 5, the linear bearing 7 slides on the guide shaft 8, so that the mounting plate 5 can move vertically up and down along the guide shaft 8, ensuring the stability and straightness of the movement of the mounting plate 5, avoiding tilting during installation, and providing a guarantee for the vertical pressing of the wire harness terminal.

[0031] Please see Figures 1-4 A mounting plate 12 is fixedly mounted with a mounting base 10 by bolts on its front side. A connecting base 14 is fixedly mounted with bolts on the upper surface of the mounting plate 5. A pressure roller 13 is fixedly mounted on the upper surface of the connecting base 14. A quick clamp 11 is rotatably connected to the top of the pressure roller 13. The top of the quick clamp 11 is rotatably connected to the inner wall of one end of the mounting base 10.

[0032] Specifically, the fixed seat 10 is fixed to the front of the mounting plate 12 by bolts, the connecting seat 14 is fixed to the upper surface of the mounting plate 5, the pressure roller 13 is fixed to the connecting seat 14, the lower end of the quick clamp 11 is rotatably connected to the pressure roller 13, and the upper end is rotatably connected to the fixed seat 10. When the quick clamp 11 is pressed down, the quick clamp 11 rotates around the fixed seat 10, and the pressure roller 13 drives the connecting seat 14 and the mounting plate 5 to move downward along the guide shaft 8, thereby realizing the downward pressing action on the plug-in fixing block assembly 4 below the mounting plate 5. By utilizing the lever principle of the quick clamp 11, a large downward pressure can be easily applied to firmly press the wire harness terminal into the thyristor insert, and the pressing process is smooth, ensuring the verticality of the pressing.

[0033] Please see Figures 1-4A plug-in fixing block assembly 4 is provided below the mounting plate 5. The upper surface of the plug-in fixing block assembly 4 is fixedly connected to the bottom surface of the mounting plate 5. Mounting holes 17 are provided on both sides of the plug-in fixing block assembly 4. A spring positioning post 18 is fixedly installed on the inner wall of each mounting hole 17.

[0034] Specifically, the plug-in fixing block assembly 4 is fixed to the bottom surface of the mounting plate 5 and moves with the mounting plate 5. Mounting holes 17 are opened on both sides of the plug-in fixing block assembly 4, and spring positioning posts 18 are installed in the mounting holes 17. When in use, the wire harness terminal is inserted into the plug-in fixing block assembly 4. The spring positioning posts 18 use the elastic force of the spring to hold the terminal in place and fix the terminal. When the quick clamp 11 is pressed down to make the plug-in fixing block assembly 4 press against the thyristor insert, the terminal is pressed into the insert. Since the clamping force of the insert on the terminal is greater than the elastic force of the spring positioning post 18, when the quick clamp 11 is lifted, the plug-in fixing block assembly 4 moves upward, and the terminal remains on the insert, realizing the separation of the terminal from the plug-in fixing block assembly 4. This avoids damage to the terminal due to improper force control during manual installation, and at the same time ensures that the terminal is accurately pressed into the insert, preventing damage to the insert.

[0035] Working principle:

[0036] In use, first place the thyristor on the positioning plate 2, and use the positioning pin 3 to insert into the thyristor positioning hole for precise positioning. Then, insert the wire harness terminal into the plug fixing block assembly 4. The spring positioning pin 18 uses its elasticity to hold the terminal in place and fix it. Next, press down the quick clamp 11. The quick clamp 11 rotates around the fixing seat 10. The pressure roller 13 drives the connecting seat 14 and the mounting plate 5 to move vertically downward along the guide shaft 8. At this time, the mounting plate 5 slides on the guide shaft 8 through the linear bearing 7 to ensure the stability and straightness of the movement. This allows the plug fixing block assembly 4 to press the terminal vertically into the thyristor insert. Since the clamping force of the insert on the terminal is greater than the elastic force of the spring positioning pin 18, when the quick clamp 11 is lifted, the plug fixing block assembly 4 moves upward with the mounting plate 5. The terminal remains on the insert and is detached from the plug fixing block assembly 4, thus completing the wire harness installation and avoiding the problem of terminal damage or insert damage during manual installation.
