TECHNICAL FIELD

[0001] The utility model relates to a centralized secondary module. BACKGROUND

[0002] The centralized secondary module is a kind of secondary equipment that is mainly used to draw together all secondary devices of the same functional unit, form a centralized schematic diagram, so that the working process of secondary system is self-evident.

[0003] To meet the connection requirements of 16-core connector or cable with external and 32-core connector or cable, the existing centralized secondary module usually involves 16-core socket and 32-core aviation plug-in terminal on the centralized secondary module, wherein the 32-core aviation plug-in terminal of the existing part structure of centralized secondary module is designed with built-in structure of centralized secondary module, i.e. nut is involved on 32-core aviation plug-in terminal, and it is installed in the shell of centralized secondary module by the action of fastening screw, wherein the connection side of the pin of 32-core aviation plug-in terminal installed in the shell is connected to the control panel inside the centralized secondary module, and the plug-in side of the pin of 32-core aviation plug-in terminal and the counter-plug end of 32-core aviation plug-in terminal are all extended to the outside of the shell of centralized secondary module.

[0004] At the same time, in the production process of 32-core aviation plug-in terminal, it is found that several nuts installed on 32-core aviation plug-in terminal are installed on 32-core aviation plug-in terminal by injection molding, i.e. 32-core aviation plug-in terminal is pre-buried with several nuts at corresponding positions before injection molding, but in actual use, it is found that the molding method of pre-buried first and then injection molded will cause slow injection efficiency in the injection molding process, which will affect the labor cost and manufacturing cost.

[0005] In addition, the installation of 32-core aviation plug-in terminal on the shell of centralized secondary module is mostly to open a counter-plug end for 32-core aviation plug-in terminal on the shell, and the shell of centralized secondary module is provided with a through slot for the counter-plug end to extend to the outside of centralized secondary module, i.e. 32-core aviation plug-in terminal and the shell of centralized secondary module are connected by assembly after separate molding, which also leads to the condition that the assembly connection between the two is quite complicated.

[0006] The existing design and installation of the 16-core connector mostly involve a special pin seat, that is, the pin seat has a side for welding and is placed on the control panel, and a groove for the plurality of pins to pass through is formed on the shell of the centralized secondary module according to the positions of the plurality of pins on the pin seat, and an external connector is installed on the shell of the centralized secondary module according to the position of the groove, and the external connector is also designed with a plurality of pin holes for the plurality of pins to pass through. In addition, since the 16-core connector has the corresponding waterproof property when the external connector is installed on the shell of the centralized secondary module, a rubber ring for sealing and waterproofing is usually designed between the external connector and the shell of the centralized secondary module, which causes the installation to be complicated and the cost to be high. SUMMARY

[0007] In view of the above problems, the present application provides a centralized secondary module with a simple structure and convenient installation of a 32-core aviation plug connector.
