Description

Technical Field

[0001] This utility model relates to the field of electronic assembly technology, and in particular to a tooling for connecting electrolytic capacitors side by side. Background Technology

[0002] Electrolytic capacitors are raised structures soldered onto circuit boards. They are attached to the board using their positive and negative leads to facilitate operation. The circuit board typically serves as the connection fixture for the electrolytic capacitors. There are many ways to arrange electrolytic capacitors, with side-by-side connections being common. Side-by-side connections make circuit routing more direct and concise, reducing wire crossings and loops, especially when a large number of similar components are needed, thus reducing wiring complexity.

[0003] However, common electrolytic capacitors are usually soldered onto the circuit board one by one, which makes disassembly and maintenance difficult. Installing them one by one on the circuit board is time-consuming and labor-intensive. When capacitors connected in parallel are damaged, they are not easy to disassemble and reassemble, which affects the use of the circuit board. In view of this, we propose a tooling for connecting electrolytic capacitors in parallel. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a tooling for connecting electrolytic capacitors side by side.

[0005] The technical solution of this utility model is as follows: A fixture for connecting electrolytic capacitors side by side includes a circuit board. An auxiliary mounting strip is installed on the top of the circuit board. Electrolytic capacitors are arrayed at the top of the auxiliary mounting strip. A positioning component is installed inside the auxiliary mounting strip. The positioning component includes a first turntable. A vertical cylinder and a spring are connected to the top of the first turntable. An anti-detachment block, a first vertical shaft, and a second turntable are provided on the vertical cylinder. A contact shaft is connected to the inner wall of the top of the auxiliary mounting strip. A contact ring is sleeved on the outer surface wall of each of the two contact shafts. A connecting shaft is connected to the bottom of each of the multiple electrolytic capacitors. A contact piece is connected to the bottom end of each of the multiple connecting shafts. A locking block is installed on the bottom wall of the contact piece.

[0006] Preferably, connecting blocks are symmetrically connected to the outer walls on both sides of the two auxiliary mounting strips, and the connecting blocks are welded to the top wall of the circuit board.

[0007] Preferably, a limiting ring is fitted onto the outer surface wall of the first turntable, and arc-shaped grooves are symmetrically formed on the inner surface wall of the auxiliary mounting strip, with a portion of the limiting ring inserted into the arc-shaped grooves.

[0008] Preferably, the anti-detachment block is disposed in the inner cavity of the vertical cylinder, and the bottom end of the first vertical shaft passes through the top opening of the vertical cylinder and is connected to the top wall of the anti-detachment block. The diameter of the anti-detachment block is larger than the diameter of the top opening of the vertical cylinder.

[0009] Preferably, a first through hole is provided on the top wall of the auxiliary mounting strip, the contact piece is adapted to the first through hole, and the contact piece is located inside the auxiliary mounting strip and connected to the top of the card block.

[0010] Preferably, a slot is provided on the top wall of the second turntable, and the bottom structure of the card block is inserted into the slot, wherein the bottom structure of the card block is adapted to the slot.

[0011] Preferably, the two protruding structures on both sides of the contact piece are symmetrically provided with second through holes, and the two contact shafts respectively pass through the second through holes at the corresponding positions, and the contact ring contacts the top of the protruding structure of the contact piece.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention achieves uniform side-by-side installation of multiple electrolytic capacitors by using a positioning component to mount them on an auxiliary mounting strip, which is then installed on a circuit board. This reduces installation difficulty. Furthermore, pressing the electrolytic capacitors releases the contact pieces from the contact ring, allowing the capacitors to rotate with the cooperation of the locking block and the slot at the top of the second turntable. Observing the auxiliary slot at the top of the electrolytic capacitors facilitates adjusting the position of the contact pieces to align with the positioning opening at the top of the auxiliary mounting strip, making it easier to remove the electrolytic capacitors from the strip. This allows for targeted disassembly and replacement of damaged electrolytic capacitors, reducing installation difficulty and improving maintenance efficiency. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1 to 5 As shown, the present invention proposes a fixture for parallel connection of electrolytic capacitors, comprising a circuit board 1, multiple connecting blocks 5 symmetrically arranged on the side walls of two auxiliary mounting strips 2, the multiple connecting blocks 5 being welded to the top of the circuit board 1; multiple contact shafts 6 respectively arranged in the inner cavities of the two auxiliary mounting strips 2, with the top ends of the contact shafts 6 connected to the top wall of the inner cavity of the auxiliary mounting strips 2, and arranged symmetrically; multiple contact rings 7 are sleeved on the outer surface wall of the multiple contact shafts 6; positive and negative long strip pins are arranged on the top wall of the inner cavity of the auxiliary mounting strips 2 (not shown in the figures); the top ends of the multiple contact shafts 6 are respectively connected to the corresponding positive and negative long strip pins; first through holes are arrayed on the top walls of the two auxiliary mounting strips 2, the multiple first through holes being arranged in a horizontal array, so that multiple electrolytic capacitors 3 are arranged side by side on the auxiliary mounting strips 2.

[0023] Furthermore, the connecting shaft 8 is located at the bottom of the electrolytic capacitor 3, the top end of the connecting shaft 8 is fixedly connected to the bottom wall of the electrolytic capacitor 3, and the bottom end of the connecting shaft 8 is connected to the top wall of the contact piece 9. The contact piece 9 is located inside the auxiliary mounting strip 2, and the contact piece 9 is adapted to the first through hole opened on the top wall of the auxiliary mounting strip 2. An auxiliary groove is opened on the top wall of the electrolytic capacitor 3, and the auxiliary groove and the contact piece 9 are arranged in a cross shape when viewed from above, which makes it convenient to observe the auxiliary groove and adjust the angle of the contact piece 9. The locking block 10 is fixedly installed on the bottom wall of the contact piece 9, which facilitates the rotation and positioning of the auxiliary electrolytic capacitor 3.

[0024] Furthermore, positioning components 4 are arranged in an array within the two auxiliary mounting strips 2. The positioning components 4 include a first turntable 41, a vertical cylinder 42, a spring 43, an anti-detachment block 44, a first vertical shaft 45, a second turntable 46, and a limiting ring 47. The first turntable 41 is located within the auxiliary mounting strip 2, and the limiting ring 47 is fixedly sleeved on the outer surface wall of the first turntable 41. Part of the structure of the limiting ring 47 is inserted into the symmetrical arc-shaped grooves on the inner walls of both sides of the auxiliary mounting strip 2 to assist the first turntable 41 in rotating within the auxiliary mounting strip 2. The bottom ends of the vertical cylinder 42 and the spring 43 are fixedly connected to the top wall of the first turntable 41. The second turntable 46 is located above the top of the spring 43, and the bottom wall of the second turntable 46 is not fixedly connected to the top wall of the second turntable 46 to assist the second turntable 46 in raising and lowering while preventing it from affecting the rotation of the second turntable 46.

[0025] The top end of the first vertical shaft 45 is fixedly connected to the bottom wall of the second turntable 46. The anti-detachment block 44 is set in the inner cavity of the vertical cylinder 42. The diameter of the anti-detachment block 44 is larger than the diameter of the opening at the top of the vertical cylinder 42. The bottom end of the first vertical shaft 45 is inserted into the inner cavity of the vertical cylinder 42 and fixedly connected to the top wall of the anti-detachment block 44. This is used to assist the second turntable 46 in lifting and lowering on the vertical cylinder 42 and to prevent the second turntable 46 from detaching from the vertical cylinder 42, which would affect subsequent use. The bottom structure of the locking block 10 is inserted into the slot opened on the top wall of the second turntable 46. This is beneficial for adjusting the position of the contact piece 9 under the rotation of the electrolytic capacitor 3, and facilitates the subsequent fixing of the position of the electrolytic capacitor 3.

[0026] In this embodiment, multiple electrolytic capacitors 3 are arranged side-by-side on the auxiliary mounting strip 2, which facilitates the direct mounting of the auxiliary mounting strip 2 onto the circuit board 1, achieving the goal of simultaneously mounting multiple electrolytic capacitors 3 onto the circuit board 1 and improving mounting efficiency. When some electrolytic capacitors 3 are damaged, the electrolytic capacitors 3 can be pressed, causing the connecting shaft 8, contact piece 9, and locking block 10 to cooperate in squeezing the second turntable 46. With the assistance of the first vertical shaft 45, anti-detachment block 44, and spring 43, the electrolytic capacitors 3 can be lowered and adjusted, causing the second through hole on the contact piece 9 to disengage from the contact shaft 6 and contact ring 7. This releases the contact shaft 6 from the restriction on the contact piece 9, making it easier to rotate the electrolytic capacitors 3 to adjust the position of the contact piece 9. At this time, the auxiliary groove on the top of the electrolytic capacitor 3 can be observed for judgment. When the position of the contact piece 9 corresponds to the position of the first through hole, the electrolytic capacitor 3 can be pulled up to complete the disassembly, enabling targeted replacement, reducing maintenance costs and difficulty, and improving the convenience of subsequent maintenance and replacement.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model.
