Abstract
Description
Technical Field

[0002] Capacitors (especially large-capacity electrolytic capacitors and power capacitors) are widely used in power electronic equipment. Their leads or terminals are typically connected to circuit boards or other devices via wires, copper busbars, or flexible connecting pieces.
[0003] In existing technologies, stress concentration occurs at the connection points between the conductors connecting the capacitor and the circuit board. Traditional rigid constraints can easily cause external forces to act directly on the connection points with the capacitor, leading to solder joint fatigue or poor contact. Furthermore, external forces acting on the conductors can cause minute displacements in the conductors, which accumulate at the connection points, resulting in oxidation, increased resistance, or even breakage.

The bottom of the wire constraint frame is provided with a positioning buckle that is fixedly connected to the substrate, and the inside of the positioning buckle is a guide ring assembly.
[0009] Furthermore, the outer peripheral wall of the connecting cover is rotatably provided with a threaded cover, which engages with the top end of the mounting housing via a thread.
[0010] Furthermore, the connector is L-shaped, with one end fixedly connected to the top wall of the connecting cover, and the inner side of the connector is arc-shaped and fits against the outer peripheral wall of the threaded cover.
[0011] Furthermore, the elastic ring has locking pins at both ends for fixing it, and wire through grooves on both sides of the elastic ring.

[0016] 1. This capacitor with a wiring harness structure, when the conductor is subjected to external tension, such as conductor shaking caused by vibration or thermal expansion caused by equipment, the conductor is first buffered and bent by an elastic ring to absorb part of the tension; if the tension continues to increase, the sliding tube in the guide ring assembly will move synchronously with the conductor, and the extension and contraction of the springs at both ends will generate reverse resistance, thereby preventing the tension from being directly transmitted to the connection point between the capacitor and the conductor, effectively preventing the connection from loosening or falling off, and ensuring the stability of the circuit connection.

Detailed Implementation
[0023] The present invention will be further described in detail below with reference to the accompanying drawings.
[0024] Example: Refer to Figure 1 - Figure 4 The present invention discloses a capacitor with a wiring harness structure, comprising:
[0025] The substrate 1 has several mounting housings 2 at its top for mounting capacitors. The top of the mounting housing 2 has a connecting cover 3, and the center of the connecting cover 3 has a plug-in platform 4. The top of the connecting cover 3 has a connector 5, which is fixedly connected to the plug-in platform 4. In use, the capacitor to be installed is inserted into the top of the mounting housing 2, and the top connecting part of the capacitor is rotated to correspond to the plug-in platform 4. The connecting cover 3 is then installed on the top of the mounting housing 2. At this time, the connecting part of the capacitor is connected to the connector 5 through the plug-in platform 4. Two wires are fixed at the bottom of the connector 5, and the wires are connected to the plug-in platform 4. Therefore, the capacitor and the wires are connected to each other through the plug-in platform 4.
[0026] The bottom end of the connector 5 is provided with a wire constraint frame 6, and the inside of the wire constraint frame 6 is provided with an elastic ring 7. The bottom end of the wire constraint frame 6 is provided with a positioning buckle 8 that is fixedly connected to the base plate 1. The inside of the positioning buckle 8 is provided with a guide ring assembly 9. Two wires are inserted into the inside of the wire constraint frame 6 and are located on both sides of the elastic ring 7 respectively. The bottom end of the wire is inserted into the inside of the guide ring assembly 9 and extends out of the guide ring assembly 9. When the wire is subjected to tension, the guide ring assembly 9 and the wire are subjected to force at the same time, so that the guide ring assembly 9 moves synchronously with the wire, avoiding the problem of the wire being stretched and falling off. On the other hand, the setting of the elastic ring 7 makes the wire form an arc bend. Therefore, when the wire is stretched, the tension of the wire is released by squeezing the elastic ring 7, thereby forming a resistance structure and avoiding problems such as the connection point falling off during daily use.
[0027] Specifically, the guide ring assembly 9 includes a sliding tube 91, which is slidably connected to the positioning buckle 8. Springs 92 at both ends of the sliding tube 91 are used to support the sliding tube 91. Since the wire is inserted into the sliding tube 91 and is fixedly connected to the sliding tube 91, the sliding tube 91 will move during the sliding process of the wire, and the springs 92 on both sides will contract and stretch respectively to form resistance, so as to avoid the wire being affected too much by the external environment and achieve the purpose of improving the stability of the wire connection.
[0028] In this embodiment, when the conductor is subjected to external tension, such as conductor shaking caused by vibration or conductor stretching caused by thermal expansion of the equipment, the elastic ring 7 first causes the conductor to form a buffer bend and absorb part of the tension. If the tension continues to increase, the sliding tube 91 in the guide ring assembly 9 will move synchronously with the conductor, and the extension and contraction of the springs 92 at both ends will generate reverse resistance, thereby preventing the tension from being directly transmitted to the connection point between the capacitor and the conductor, effectively preventing the connection from loosening or falling off, and ensuring the stability of the line connection.
[0029] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the outer peripheral wall of the connecting cover 3 is rotatably provided with a threaded cover 10, which is threadedly engaged with the top end of the mounting housing 2.
[0030] In this embodiment, the threaded cap 10 is used to fix the connecting rod to the top of the mounting housing, and the internal thread inside the threaded cap 10 engages with the external thread at the top of the outer peripheral wall of the mounting housing 2 to fix the connecting cap 3 to the top of the mounting housing 2.
[0031] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the connector 5 is L-shaped, with one end fixedly connected to the top wall of the connector 3. The inner side of the connector 5 is arc-shaped and fits against the outer peripheral wall of the threaded cover 10.
[0032] In this embodiment, the connector 5 is used to connect the wire constraint frame 6 and the connecting cover 3 to each other, and the wires inside the connector 5 are connected to the plug-in platform 4. The arc-shaped inner side improves the stability of the rotational connection between the threaded cover 10 and the connecting cover 3.
[0033] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the elastic ring 7 has locking pins 11 at both ends for fixing the elastic ring 7, and wire through grooves 12 on both sides of the elastic ring 7.
[0034] In this embodiment, the snap-fit pin 11 is used to fix the end of the elastic ring 7, and the wire through groove 12 is used to guide the wire, thereby improving the stability between the wire and the elastic ring 7 when the wire is under tension.
[0035] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the guide ring assembly 9 includes:
[0036] The sliding tube 91 is inserted into the positioning buckle 8. Springs 92 are provided at both ends of the sliding tube 91. The other end of the springs 92 is fixedly connected to the positioning buckle 8. A guide sleeve 93 is provided inside the sliding tube 91.
[0037] In this embodiment, since the wire is inserted inside the sliding tube 91 and is fixedly connected to the sliding tube 91, the sliding tube 91 will move during the sliding process of the wire, and the springs 92 on both sides will contract and stretch respectively to form resistance, so as to avoid the wire being affected too much by the external environment and achieve the purpose of improving the stability of the wire connection.
[0038] In a further preferred embodiment of this utility model, such as Figure 2 As shown, connecting ears 13 extend from the four corners of the substrate 1, and mounting holes are provided at the center of the connecting ears 13.
[0039] In this embodiment, the connecting ear 13, in conjunction with the mounting hole, is used to mount the substrate 1 onto the corresponding circuit board.
[0040] The implementation principle of the above embodiment is as follows: When the conductor is subjected to external tension such as vibration or thermal expansion, the conductor is first bent in an arc shape within the conductor constraint frame 6 by the elastic ring 7, absorbing part of the tension and buffering the stress; if the tension continues to increase, the conductor drives the sliding tube 91 in the conductor ring assembly 9 to move synchronously. At this time, the springs 92 at both ends of the sliding tube 91 are compressed and stretched respectively, generating reverse resistance to dynamically offset the tension. The elastic ring 7 buffers and the sliding tube 91 dampens, ensuring that the tension cannot be directly transmitted to the connection point between the capacitor and the conductor, thereby avoiding loosening or falling off the connection and maintaining the stability of the line.
[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
