Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and in particular to an external terminal block for airborne equipment. Background Technology

[0002] Terminal blocks are a crucial component for achieving electrical connections in airborne equipment. Existing terminal block covers often use screws for mounting, requiring disassembly and reassembly for both wiring and maintenance. This process is cumbersome, inefficient, and prolongs equipment maintenance time. Furthermore, small parts like screws are difficult to locate if dropped in the complex onboard environment, posing a safety hazard. In addition, when multiple terminals are involved, the cover is typically a single unit; disassembly removes all terminals, leaving them unprotected and preventing individual terminal disassembly and maintenance. Utility Model Content

[0003] The purpose of this invention is to provide an easy-to-install terminal block, optimize the disassembly and maintenance process, and eliminate safety hazards.

[0004] The technical solution of this utility model:

[0005] A terminal block for easy installation includes a wiring module 1, a mounting module 2, connectors 1-3 and 2-4; the mounting module 2 and the wiring module 1 are combined together by connectors 1-3 and 2-4 to form a stable connection; wherein: the mounting module 2 is located at both ends of multiple sets of wiring modules 1, the connectors 1-3 are installed in the through grooves on the back of each module, and the connectors 2-4 are installed between adjacent modules.

[0006] The wiring module 1 includes a support 11, a protective cover 12, and a compression spring 13; wherein, the protective cover 12 is installed in the guide groove at the upper end of the support 11; the compression spring 13 is placed in the guide groove at the rear end of the support and is located between the protective cover 12 and the support 11.

[0007] The support 11 has guide grooves 111 at both the front and rear ends of its upper end; a blind hole 112 is opened at the bottom of the rear guide groove for the installation of the compression spring 13.

[0008] The support 11 has mounting grooves 1-113 and 2-114 on its back and side walls, which are used for the installation of connectors 1-3 and 2-4, respectively; the cross-section of mounting grooves 1-113 and 2-114 is rectangular.

[0009] The protective cover plate 12 has columnar bosses 121 at its four corners; the diameter of the bosses 121 is slightly smaller than that of the support guide groove 111.

[0010] The protective cover 12 has anti-slip parallel protrusions 122 on one side; the protective cover 12 has text information 123 engraved on both sides for identification and prompting purposes.

[0011] The number of compression springs 13 is 2; the compression springs 13 are in a compressed state after installation.

[0012] After installation, the protective cover plate 12 can slide along the guide groove 111. The maximum movement distance of the protective cover plate 12 along the guide groove is L1. When the distance between the columnar boss 121 of the protective cover plate and the bottom of the guide groove at the rear end of the support is L2, the front columnar boss 121 can be dislodged from the guide groove 111, and the protective cover plate 12 can be rotated and lifted about the rear columnar boss as the axis.

[0013] The mounting module 2 has mounting grooves 3-21 and 4-22 on its back and side walls, which are used for the installation of connectors 1-3 and 2-4, respectively; the mounting grooves 3-21 and 4-22 have the same cross-sectional shape and size as the mounting grooves 1-113 and 2-114 on the support 11.

[0014] The mounting module 2 has two through holes 23 on its surface for mounting the terminal block on the airborne equipment.

[0015] The cross-section of connector 1 is rectangular, and the cross-section of connector 2 is H-shaped.

[0016] The beneficial effects of this utility model are as follows: This utility model proposes a terminal block that is easy to install. The protective cover of the terminal block and the mounting base are integrated into one structure, and the protective cover can be opened at a certain angle to facilitate the wiring or maintenance of external cables. While ensuring protection, it optimizes the disassembly and maintenance process and eliminates the safety hazard of falling or losing mounting components. Furthermore, it features a modular design, facilitating low-cost serialization. Its advantages are particularly evident in applications requiring multiple terminal blocks in airborne equipment. In addition, the modular design allows each terminal block's protective cover to be opened individually, providing a solution for single-line disassembly and maintenance in multi-line equipment.
