[0001] The utility model belongs to the technical field of circuit boards, and more specifically, particularly relates to a chip aluminum electrolytic capacitor packaging structure. Background Art

[0002] As a new passive component with light weight, thin thickness and small size, SMD aluminum electrolytic capacitor is suitable for various electronic products with compact structure, small size and high precision. Its application field is very broad, especially concentrated in communication equipment, computers and peripheral accessories, LCD TVs, portable DVD players, GPS positioning guidance, car TV / DVD / RADIO, HDTV (including digital set-top boxes), LCD, ultra-thin DVD, set-top boxes, security equipment and fire equipment, mobile power supplies, etc. In addition, there are: financial and commercial ATM machines, high-end computers, POS machines, cash registers, mobile scanners, code identifiers, various types of vehicle-mounted electrical appliances, medical instruments and equipment, precision instruments and meters, industrial equipment or control parts of household appliances, electronic toys, electric vehicle control parts, etc.

[0003] Based on the above, the inventors have discovered the following problems: existing chip aluminum electrolytic capacitors are directly attached to the circuit board through connectors during packaging, but during welding or use, when shaking occurs, the chip aluminum electrolytic capacitors may be offset or fall off in the connectors, causing inconvenience to the staff.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a chip aluminum electrolytic capacitor packaging structure is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of the chip aluminum electrolytic capacitor packaging structure of the utility model are achieved by the following specific technical means:

[0006] A chip aluminum electrolytic capacitor packaging structure comprises a connector, a group of frames are installed inside the connector, a limiting mechanism is installed inside the frame, a capacitor body is bonded and installed on the surface of the connector, and a group of through holes are opened on the surface of the connector.

[0007] Furthermore, a group of contacts are connected and installed at the bottom end of the capacitor body, and one end of the contact passes through the through hole and extends to the outside.

[0008] Furthermore, the limiting mechanism comprises a spring, a limiting block is installed at one end of the spring, a connecting rod is fixedly installed at one end of the limiting block, and an arc-shaped clamping block is fixedly installed at one end of the connecting rod.

[0009] Furthermore, a group of arc-shaped grooves are formed on the inner wall of the connecting piece, and the arc-shaped clamping blocks match the arc-shaped grooves.

[0010] Furthermore, a plurality of groups of arc-shaped limiting grooves are formed on the surface of the capacitor body, and the arc-shaped clamping blocks match the arc-shaped limiting grooves.

[0011] Furthermore, one end of the arc-shaped clamping block is connected and installed with a rubber pad.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the cooperation between the arc-shaped clamping block and the arc-shaped limiting groove, when the staff installs the capacitor body, they can first install the contact to the inside of the through hole, and then manually press the arc-shaped clamping block to the inside of the arc-shaped groove. At the same time, the capacitor body can be directly pressed to the surface of the connector. The arc-shaped clamping block will automatically fit into the inside of the arc-shaped limiting groove under the action of the spring, and then the capacitor body can be limited and fixed, which indirectly improves the fixing efficiency and avoids the staff from offsetting or falling off during the welding process. The operation steps are very simple and the design greatly increases the practicality.

[0014] Through the design of the rubber pad, when the arc-shaped clamping block is inserted into the arc-shaped limiting groove, the rubber pad can effectively protect the surface of the capacitor body, preventing the arc-shaped clamping block from wearing or damaging its surface, thereby indirectly improving the protection efficiency and being very convenient.

[0028] The limiting mechanism comprises a spring 8 , a limiting block 9 is installed at one end of the spring 8 , a connecting rod 11 is fixedly installed at one end of the limiting block 9 , and an arc-shaped clamping block 12 is fixedly installed at one end of the connecting rod 11 .

[0029] A group of arc-shaped grooves 10 are formed on the inner wall of the connecting member 1 , and the arc-shaped clamping blocks 12 match the arc-shaped grooves 10 .

[0030] Among them, the surface of the capacitor body 2 is provided with a plurality of groups of arc-shaped limit grooves 4, and the arc-shaped clamping block 12 matches the arc-shaped limit grooves 4; through the cooperation between the arc-shaped clamping block 12 and the arc-shaped limit grooves 4, when the staff installs the capacitor body 2, they can first install the contact 3 to the inside of the through hole 6, and then manually press the arc-shaped clamping block 12 to the inside of the arc-shaped groove 10, and at the same time, the capacitor body 2 can be directly pressed to the surface of the connector 1, and the arc-shaped clamping block 12 will automatically snap into the inside of the arc-shaped limit groove 4 under the action of the spring 8, so that the capacitor body 2 can be limited and fixed, which indirectly improves the fixing efficiency and avoids the phenomenon of displacement or falling off during welding by the staff.
