Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a connector housing for high-efficiency heat dissipation in the field of fiber optic connectors. Background Technology

[0002] Fiber optic connectors are patch cords used to connect devices to fiber optic cabling. They are generally used for connections between optical transceivers and terminal boxes, and are used in fields such as fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks. Because a lot of heat is generated when signals are transmitted at high speed, fiber optic connectors are small in size, compact in structure, easy to couple, and widely used. However, they cannot meet the heat dissipation requirements of higher power laser transmission. This utility model aims to solve the problem of better and more efficient heat dissipation. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a connector cover with high-efficiency heat dissipation.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: it includes a metal shell, a radiator assembled and connected to the metal shell, and a spring-loaded piece that is in spring-loaded contact with the radiator and fixedly connected to the metal shell. The metal shell is provided with a top side surface. The radiator includes a heat dissipation body and heat dissipation teeth fixedly connected to the top of the heat dissipation body. The radiator is mounted on the top side surface. The spring-loaded piece includes a connecting part fixedly connected to the metal shell, a square spring piece body fixedly connected to the connecting part, and a spring piece fixedly connected to the spring piece body and in pressure contact with the heat dissipation body. The spring piece body is located on the upper side of the heat dissipation body and there is a gap between it and the heat dissipation body.

[0005] Preferably, the heat dissipation body has a heat dissipation top surface, the heat dissipation top surface has linearly arranged protruding fixing strips, a heat dissipation groove is formed between two adjacent protruding fixing strips, and the heat dissipation teeth are arranged on the protruding fixing strips.

[0006] Preferably, the main body of the spring plate includes a short side frame and a long side frame perpendicular to the short side frame. There is a gap between the long side frame and the top side of the heat dissipation body. The connecting part is fixedly connected to the short side frame. The cross-section of the long side frame is L-shaped.

[0007] The beneficial effects of this utility model are that it provides a connector housing with high-efficiency heat dissipation. The heat sink is installed in the metal shell through the mounting hole. The spring clip elastically clamps the heat sink body between the spring clip and the metal shell, ensuring that the heat sink is fixed between the spring clip and the metal shell, making the overall structure compact. The heat generated when the electronic connector transmits signals is dissipated to the outside through the heat sink. The spring clip body is located on the upper side of the heat sink body and has a gap between it and the heat sink body, which accelerates the heat dissipation efficiency. The design of the heat dissipation groove further improves the heat dissipation efficiency of the heat sink. The cross-section of the long side frame is L-shaped, which increases the strength of the long side frame. While ensuring that there is a gap between the long side frame and the top side of the heat sink body, it also increases the strength of the long side frame, ensuring the stability of the overall structure.

The cross-section of the long side frame 322 is L-shaped, increasing its strength and ensuring that while there is a gap 4 between the long side frame 322 and the top side surface 11 of the heat dissipation body 21, the strength of the long side frame 322 is also increased, ensuring the stability of the overall structure. The spring plate 33 is located inside the short side frame 321 and elastically abuts against the top side surface 11, resulting in a simple and compact overall structure.
