In addition, the electrical equipment using the existing wiring terminals can usually only meet the connection of one set of electrical equipment. The scalability of the electrical equipment connection is inhibited, and it may be necessary to increase the investment cost and operation and maintenance costs. For this reason, an integrated double-layer multi-hole test terminal is designed to solve the above problems. Utility Model Content

[0017] The utility model provides an integrated double-layer multi-hole test terminal, comprising a socket 1, a plug 3 is plugged into the upper end of the socket 1, a plug outer plate 4 is fixedly connected to the outer side of the plug 3, a short-circuit bar 6 is fixedly connected to the outer plate 4, a plurality of grooves 7 are arranged opposite to each other on the outer side of the short-circuit bar 6, and a plug interface 8 is plugged into the inner side of the groove 7.

[0018] Furthermore, the outer end of the socket 1 is also fixedly connected to a socket outer plate 2, the material of the socket outer plate 2 is the same as that of the plug outer plate 4, which protects the internal socket 1 and the plug 3. The plug 3, the plug outer plate 4, the short-circuit strip 6 and the plug interface 8 inside the groove 7 constitute the plug accessory, and the socket 1 and the socket outer plate 2 constitute the base. The entire terminal block is mainly composed of two parts: the base and the plug accessory. The base is similar to the conventional terminal block structure, but a pair of (or a single) plug interface 8 is designed in the middle groove 7 to meet the installation of the plug accessory and realize the conduction and fixation of the electrical components. The diameter of the plug interface 8 is the standard width of 8 mm.

[0019] Furthermore, an identification plate 5 is fixedly connected to the upper end of the outer side of the plug outer plate 4, which facilitates the viewing and differentiation of devices of different models and avoids the situation where electrical devices are plugged into the outside of a socket 8 of a different model.

[0020] Furthermore, the short-circuit bar 6 is made of insulating material to avoid leakage conduction and ensure safety during use.

[0021] Furthermore, one end of the plug outer plate 4 is connected to two fixing screws 9 by means of screws. The two fixing screws 9 are symmetrically distributed on both sides of the short-circuit bar 6. The plug outer plate 4 adopts two semi-interpenetrating fixing screws 9 and a fully interpenetrating fixing screw 9, which is convenient for the rapid assembly of individual components of the aviation plug and the replacement of damaged plug-ins.

[0022] The working principle of the utility model: the terminal block is mainly composed of a base and a plug accessory. The plug accessory is similar to a two-pin plug, with a pair of (or a single) wiring ports designed on the upper part and universal test plug-in and pull-out ports designed on both sides. The plug accessories can be freely combined into test plugs of different specifications through the fixing screw 9, so as to realize the rapid plug-in and pull-out of wiring harnesses of various electrical equipment. The integrated double-layer multi-hole test terminals can be freely combined in the electrical connection. Taking the insulation design on the left and right sides of the terminal block as an example, the electrical conduction of the upper and lower terminal blocks can be achieved by installing short-circuit pieces on the sides of the terminal block base, and the electrical connection on the left and right sides can be achieved by installing short-circuit pieces on the left and right sides of the upper part of the terminal block plug accessory.
