Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Referring to fig. 1-2, a capacitor guide pin comprises a lead wire 1, a connecting portion 2 and an aluminum tongue 3, the aluminum tongue 3 is riveted on an electrode aluminum foil, one end of the connecting portion 2 is provided with a bent jack 21, the jack 21 is located at the central line position of the connecting portion, the tail end of the lead wire 1 is also of a corresponding bent structure and is inserted into the jack from the side and fixedly connected with the connecting portion, the other end of the connecting portion 2 is provided with a slot 22, the slot 22 is arranged in a manner of deviating from the central line of the connecting portion, the slot 22 is arranged in an inclined manner, one end of the aluminum tongue 3 is inserted into the slot 22 and fixedly connected with the connecting portion after being bent, and. Specifically, a three-section type connection mode is adopted, the quality and the production efficiency of the capacitor are improved, the capacitance of the capacitor is increased by adopting a structure that the aluminum tongue deviates from the axis, and the toughness of the guide pin of the capacitor is enhanced through the design of a reinforcing rib; the bending part at the tail end of the lead is matched with the bent jack 21, so that the integrity between the bending part and the jack can be improved, and the lead is not easy to separate and break; compared with the traditional guide pin with the same length, the aluminum tongue 3 has shorter length, thereby being more beneficial to the requirement of miniaturization of electronic products.

In this embodiment, the lead 1 is a cylindrical thin rod, and the joint of the lead 1 and the connecting portion 2 is fixed by welding.

In this embodiment, the aluminum tongue 3 is a sheet structure, and the joint of the aluminum tongue 3 and the connecting portion 2 is fixed by welding.

In this embodiment, the reinforcing rib 4 is gradually inclined from the connecting portion toward the aluminum tongue 3. The reinforcing ribs 4 support the aluminum tongue 3 and increase the firmness between the aluminum tongue 3 and the connecting part 2.

In this embodiment, a triangular reinforcing block 5 is provided at a contact portion between the lead 1 and the outer surface of the connection portion 2. The reinforcing block 5 can increase the firmness between the lead 1 and the connection portion 2.

In this embodiment, the aluminum tongue is provided with a plurality of riveting holes connected with the capacitor aluminum foil. The riveting hole is convenient to be connected with the capacitor aluminum foil in the later processing; the shape of the riveting hole is round or square.

The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by the technical solution of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
