Multi-circuit board cage type installation structure

The invention discloses a multi-circuit board cage type installation structure. The installation structure comprises functional circuit boards, locking sleeves, a mother board, a support skeleton and a base board. Mother board installation holes I and mother board installation holes II are arranged in the base board. The mother board is fixed on the base board via the mother board installation holes I and the mother board installation holes II. The support skeleton is a trunk bulkhead. Installation grooves are symmetrically arranged in two sides in the trunk bulkhead. The locking sleeves are arranged on two sides of each of the functional circuit boards. The functional circuit boards are inserted into the installation grooves and fixed on the support skeleton via the locking sleeves. At least one functional circuit board is installed in the support skeleton in a laminated manner, and is connected with the mother board via connector assemblies. According to the invention, functionalized integration is performed on an electronic device with single function, so the number of electronic elements is reduced and cost is reduced; and elements of different electronic devices are integrated in one circuit board, so occupied space for installation of finished pieces is greatly reduced, thereby facilitating min design of the structure.
