Preferably, the limiting structure is arranged at the middle section.

Preferably, the limiting structure is a convex structure, and a clamping groove is formed in the inner wall of the accommodating cavity; the clamping groove is matched with the protruding structure.

Preferably, the number of the clamping grooves is 2, and the number of the protruding structures is 2.

Preferably, a step surface is arranged at the bottom of the clamping groove, and when the core is fixed in the accommodating cavity, the protruding structure abuts against the step surface.

Preferably, a gap exists between the insert piece and the card slot.

Preferably, the core to which the insert is fixed at the center of the receiving cavity.

Preferably, the lead section of the insert is provided with a plurality of terminals.

Preferably, the insert is of a flat construction.

Compared with the prior art, the welding section of the utility model is of a flat structure and is provided with a welding hole (namely, the welding section of the insertion sheet is hollowed), thereby facilitating the adoption of inverse resistance welding and the realization of automatic production; even if inverse resistance welding is not adopted, tin can flow into a gap between the insertion sheet and the end face of the core more easily if tin soldering is adopted, the welding is firmer, and the tin is not easy to fall off. Be equipped with the screens structure simultaneously, can make whole core be located the center department that holds the chamber, avoid encapsulating in-process core to remove to lead to the core not holding chamber center department, influence the shaping quality of product. To sum up, the utility model has the advantages of simple structure, high forming quality and long service life.

Detailed Description

For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.

A capacitor with an improved welding structure comprises a shell 1, a core 2 and an inserting piece 3, wherein the inserting piece 3 is fixed on two end faces 21 of the core, and the inserting piece 3 abuts against the inner wall of a containing cavity 13 of the shell; the insertion piece comprises a welding section 33, a lead section 31 and a middle section 32, wherein the welding section 33 is of a flat structure, and the welding section is provided with a plurality of welding structures; the inserted sheet still includes limit structure, it corresponds to hold the chamber limit structure is equipped with the screens structure.

Wherein, it should be noted that the fixed mode of cooperation between limit structure and the screens structure does not do the special limitation, as long as can realize fixing the core in the structure that holds chamber center department, all belong to the utility model discloses a protection scope.

In order to better weld and fix the insertion sheet on the end face of the core, the welding structure is a welding through hole 311 or a welding hole groove.

In order to realize a good welding effect, the welding section is welded and attached to the centers of the two end faces, and the welding section is flush with the core.

Wherein, an implementation mode of the limiting structure: the limiting structure is arranged at the middle section and is a convex structure 34, and a clamping groove 12 is formed in the inner wall of the accommodating cavity; the card slot 12 cooperates with the raised formation 34.

In order to realize good spacing fixed, the draw-in groove is equipped with 2, protruding structure is equipped with 2.

In order to ensure that the bottom of the core is not contacted with the bottom of the accommodating cavity, a step surface 11 is arranged at the bottom of the clamping groove, and when the core is fixed in the accommodating cavity, the protruding structure is abutted against the step surface.

In order to facilitate the glue to flow in and improve the product quality, a gap 4 is arranged between the inserting piece and the clamping groove.

The core fixed with the inserting sheet is fixed at the center of the accommodating cavity, so that one end of the core is prevented from abutting against the inner wall of the accommodating cavity or the gap between the core and the inner wall of the accommodating cavity is prevented from being too small, and the forming quality of a product is effectively improved.

In order to facilitate the installation of the lead wires, the lead wire section of the insert sheet is provided with a plurality of terminal ends 311.

In order to facilitate the installation of the insert sheet, the insert sheet is of a flat structure.

Compared with the prior art, the welding section of the utility model is of a flat structure and is provided with a welding hole (namely, the welding section of the insertion sheet is hollowed), thereby facilitating the adoption of inverse resistance welding and the realization of automatic production; even if inverse resistance welding is not adopted, tin can flow into the gap of the end face of the core more easily if tin soldering is adopted, the welding is firmer, and the tin is not easy to fall off. Be equipped with the screens structure simultaneously, can make whole core be located the center department that holds the chamber, avoid encapsulating in-process core to remove to lead to the core not holding chamber center department, influence the shaping quality of product. To sum up, the utility model has the advantages of simple structure, high forming quality and long service life.

The present invention is not limited to the above embodiment, and if various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, they are intended to be covered if they fall within the scope of the claims and the equivalent technology of the present invention.
