The invention relates to a DLC (Digital Loop Carrier) optical fiber connector, which comprises a positioning shell and two plug modules which are installed on the positioning shell and are arranged in parallel on the left and the right. The positioning shell comprises an upper cover shell and a lower cover shell which are vertically arranged in a split way and are fixedly installed together. A rotation stopping structure, a radial limiting structure and an axial limiting structure are arranged on each plug module. A rotation stopping matching part, a radial limiting matching part and an axial limiting matching part which are respectively matched with the rotation stopping structure, the radial limiting structure and the axial limiting structure in a backstop way to prevent each plug module from rotating, radially moving and axially moving are arranged on the positioning shell. By using the DLC optical fiber connector, the problems that the machining difficulty of the positioning shell of the existing DLC optical fiber connector is great and the structural strength is not high are solved.

The invention discloses a non-bearing wall integrated heat preservation structure. The non-bearing wall integrated heat preservation structure comprises a light strip plate, a bonding layer and a heat preservation layer which are sequentially arranged; a plurality of first mounting through holes are formed in the light strip plate in the thickness direction of the light strip plate; a heat preservation plate and the light strip plate are pre-connected through the bonding layer, and a plurality of second mounting through holes are formed in the surface of the heat preservation plate; and anchoring parts are mounted in the first mounting through holes and the second mounting through holes and matched with the second mounting through holes, and the diameter of the first mounting through holes is larger than that of the anchoring parts, so that filling gaps are formed between the interiors of the first mounting through holes and the anchoring parts. The ends, away from the heat preservation layer, of the filling gaps serve as injection openings, grouting materials are injected into the filling gaps, and the grouting materials are fixedly connected with the anchoring parts and the light strip plate correspondingly after reaching the design strength so as to fix the light strip plate and the heat preservation plate secondarily. Through the specific form of the non-bearing wall integrated heat preservation structure, the purposes that the non-bearing wall integrated heat preservation structure is simple in structure, good in heat preservation effect and firm in fixing are achieved.
