Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit lead wire bundling technology, specifically a wire bundling assembly based on IGBT integrated circuits. Background Technology
[0002] In IGBT integrated circuits, the IGBT module needs to be positioned separately, and it is spatially separated from the driver IC, actuators, etc. Therefore, it is necessary to connect the input and output of the IGBT module to the pins of other components via leads. However, the lead material used for signal transmission is often relatively flexible and short (usually within 5 cm). Given the large number of IGBT modules and their closely packed arrangement, the leads are close together and prone to crossing, posing potential risks to signal transmission and troubleshooting. Current wire-binding assemblies are often designed for long leads, fixing the redundant length at a specific location on the circuit board. Therefore, they are not suitable for the short and flexible leads in IGBT integrated circuits. Utility Model Content

Detailed Implementation
[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Example: Please see Figures 1 to 4 This utility model provides a technical solution for a wire harness assembly based on an IGBT integrated circuit: A wire harness assembly based on an IGBT integrated circuit includes an IGBT module 1, a circuit board 2, an actuator 3, leads 4, and a wire gathering assembly 5. The IGBT module 1 and the actuator 3 are fixed on the circuit board 2 and electrically connected by the leads 4, allowing the output signal of the IGBT module 1 to be transmitted to the actuator 3. The wire gathering assembly 5 includes a slide rail 51 and a support assembly 52. The support assembly 52 includes a support block 521 and a support claw 522. The support assembly 52 is used for... The support lead 4 and the slide rail 51 are fixed on the circuit board 2, serving as the fixing platform for the entire convergence assembly 5. The support block 521 is set on the slide rail 51, so the support block 521 can move along the slide rail 51 and can stop at any position on the slide rail 51. The support claw 522 is vertically and movably installed on the support block 521. The support claw 522 can spring up under the action of the spring 523, and the support claw 522 contacts the lead 4 and supports the lead 4, thereby enabling each convergence assembly 5 to support one lead 4.
[0013] In a preferred embodiment, the slide rail 51 is fixed to the circuit board 2 by means including but not limited to adhesive bonding, which is a common technical feature in the art and will not be described in detail here.
[0014] In a preferred embodiment, the axis of motion of the support claw 522 relative to the support block 521 is perpendicular to the axis of motion of the support block 521 relative to the slide rail 51, so that the support claw 522 can support the lead wire 4.
[0015] In a preferred embodiment, the support assembly 52 further includes a spring 523. The support block 521 is provided with a support column 5212, and the support claw 522 is provided with a sleeve 5221. The sleeve 5221 is linearly movably mounted on the support column 5212. One end of the spring 523 is fixedly connected to the sleeve 5221, and the other end is fixedly connected to the support column 5212. Under the elastic force of the spring 523, the sleeve 5221 moves linearly on the support column 5212, so that the support claw 522 supports the lead wire 4.
[0016] In a preferred embodiment, the sleeve 5221 is further provided with a limiting protrusion, and the support column 5212 is further provided with a limiting matching protrusion to ensure that the sleeve 5221 will not fall off the support column 5212.
[0017] In a preferred embodiment, the retracting assembly 5 further includes a tear strip 53, which is disposed on the support block 521. The bottom end of the sleeve 5221 is provided with a buckle 5222. The buckle 5222 contacts and engages with the tear strip 53 to compress the spring 523. Before supporting the lead wire 4, the tear strip 53 compresses the buckle 5222, thereby generating elastic potential energy in the spring 523, which pulls the tear strip 53 off the support block 521. The buckle 5222 loses its pressure, thereby causing the spring 523 to spring up the sleeve 5221.
[0018] In a preferred embodiment, at least one support component 52 is provided on the slide rail 51, and the number of gathering components 5 is the same as that of the lead wires 4.
[0019] As a preferred embodiment, the length of the slide rail 51 can be adjusted to suit the application, and the number of support components 52 can be set according to the application requirements.
[0020] In a preferred embodiment, a limiting bolt is provided between the slide rail 51 and the support block 521. After the support block 521 is moved to the designated position, the limiting bolt is tightened to fix the position of the support block 521 and prevent further slippage.
[0021] The working principle of this utility model is as follows: The IGBT module 1 and the actuator 3 are electrically connected through the lead wire 4. The slide rail 51 is cut according to the distance between the IGBT module 1 and the actuator 3, and the slide rail 51 is fixed on the circuit board 2 between the IGBT module 1 and the actuator 3. Support components 52 are set on the slide rail 51. The position of each support component 52 on the slide rail 51 is adjusted. At this time, the tear strip 53 compresses the buckle 5222, thereby causing the spring 523 to generate elastic potential energy, and the lead wire 4 is hung on the support claw 522. Then, the tear strip 53 is pulled off the support block 521, the buckle 5222 loses pressure, thereby causing the spring 523 to spring up the sleeve 5221. The sleeve 5221 moves linearly on the support column 5212, lifting the support claw 522, thereby supporting the lead wire 4. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
