Description

Assembly positioning structure Technical Field The utility model relates to the field of electronic components, in particular to a combination positioning structure. Background Electronic components are the basic components that make up electronic circuits and electronic devices that have specific electrical properties and functions that, through interconnection and cooperation, perform the operation of various electronic systems. In order to ensure the heat dissipation of the chip used, it is common practice to attach an aluminum heat sink to the chip, but when the aluminum heat sink and the chip are spliced together, the aluminum heat sink and the chip may deviate, resulting in a reduced heat dissipation effect. The inventor finds that the prior art has the following problems in the process of realizing the application that the prior assembling and positioning structure generally comprises a bolt, a chip, an aluminum radiating fin and other structures, the prior chip and the aluminum radiating fin lack a mechanism capable of positioning during splicing, the situation of splicing deviation is likely to occur, and the prior chip also lacks a mechanism capable of fixing during splicing, which may cause the situation of sliding of the chip during splicing. Accordingly, one skilled in the art provides a positioning structure for solving the above-mentioned problems. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a combined positioning structure, which can ensure that a bottom chip cannot move through a positioning mechanism and can ensure that the chip and a radiating fin are spliced more accurately through a plurality of positioning rods.
