Problems solved by technology

A terminal abutment with two or more threaded holes of different specifications is pre-buried in the base of the terminal board. The terminal adopts a new structure of a hexagonal shape in the middle of tapping threads on both sides, which solves the problem of re-opening the mold when replacing the terminal. Cost and extra terminals affect wiring and electrical safety issues

Embodiment 1

[0038] This embodiment relates to a motor, on which a motor terminal board with detachable and replaceable terminal posts is installed. Such as figure 1 , Figure 4 and Figure 5 As shown, the motor terminal board includes three parts: a terminal board base 1 , a terminal base 2 and a double-threaded terminal 3 . Fastening holes 4 are arranged on the terminal board base 1, and screws can pass through the fastening holes 4 to fix the terminal board on the motor casing. The terminal base 2 is a cuboid metal block with threaded holes on the upper surface, which is pre-embedded and injection molded on the terminal board base 1 . Such as image 3 As shown, the double-thread terminal 3 is a copper part with threads at both ends and a hexagonal structure in the middle. Such as figure 2As shown, the threaded hole on the terminal base is a threaded hole whose diameter decreases stepwise from top to bottom. And the threaded hole includes two layers of threads, and the diameter ...

Abstract

The invention belongs to the technical field of motors, and discloses a terminal post-detachable and replaceable motor terminal board and a wiring method thereof. The motor terminal board comprises aterminal board base, a terminal post base and a double-threaded terminal post. A fastening hole is arranged on the base of the terminal board, and screws can pass through the fastening hole to fix theterminal board on the motor housing; the terminal post base is a cuboid metal block with a threaded hole on the upper surface, and is pre-embedded and molded on the terminal board base; the double-threaded terminal post is a copper part with a hexagonal structure in the middle with threads at both ends. Only changing the shape of terminal base and the number of threaded layers can increase or decrease the number of terminals and replace the specifications of terminals. The invention can meet the requirements of different power density motor rated current on the diameter and quantity of terminal blocks, and has the advantages of simple implementation scheme and convenient wiring. The invention meets electrical safety requirements and saves production costs.

Description

technical field [0001] The invention belongs to the technical field of electricity, and in particular relates to a motor wiring board with detachable and replaceable wiring posts and a wiring method thereof. Background technique [0002] At this stage, most types of motors use the casing and junction box components of the three-phase asynchronous motor. The permanent magnet synchronous motor with the same specification base has 1-2 times higher power density than the three-phase asynchronous motor. The rated permanent magnet motor The current is also 1.5-2 times larger than that of the asynchronous motor, but the continuous current allowed by the terminal on the terminal board is related to the diameter and material of the terminal. When the continuous current of the motor exceeds the allowable value of the terminal, it is necessary to re-open the mold for the terminal board and the terminal box, which increases the production cost. Moreover, the wiring methods of different...
