Description
Technical field
The utility model belongs to electroporation field more particularly to a kind of motor wire-connecting board of detachable and interchangeable binding post.
Background technique
The motor of most of type all borrows the casing and junction box assembly of threephase asynchronous at this stage, uses same rule
The permanent magnet synchronous motor of lattice base is 1-2 times bigger than the power density of threephase asynchronous, and the rated current of magneto also compares
Asynchronous machine is 1.5-2 times big, but the follow current that the binding post on terminal plate allows is related with the diameter of binding post and material.
When the follow current of motor is more than the permissible value of binding post, it is necessary to which butted line plate is re-molded with terminal box, increases life
Produce cost.And the mode of connection of different motors is different, and the quantity of lead-out wire has 3 or 6, wiring on existing terminal plate
Column is all 6, and when lead-out wire is 3, extra binding post will affect cabling and electrical safety, inconvenient and dangerous.
The patent of 203906502 U of Chinese utility model patent CN discloses a kind of New-type electric machine terminal plate injection moulding screw,
The patent changes the wiring post head of existing terminal plate, can effectively prevent binding post and is pulled out and rotates, but this wiring
Rod structure is complicated, and difficulty of processing is high, increases production cost, and the patent does not consider motor electrical safety standards, binding post
Head diameter is significantly less than threaded portion diameter, and there are electrical safety hidden danger.
The motor that the patent of 204131293 U of Chinese utility model patent CN discloses one kind and can splice on demand connects
Line plate, the terminal plate are formed by multiple identical module splicing fixations, can increase and decrease according to demand patch panel module and connect to realize
The increase and decrease of terminal, but the cooperation of each intermodule of this terminal plate is not fixed firmly and leans on, and needs fixed hole position more, installation is complicated, connects
Line plate integral strength is lower.
The patent of 207150315 U of Chinese utility model patent CN discloses a kind of Combined motor terminal plate, the wiring
Plate is made of two fixing pieces of three binding posts and link column, and binding post lower end is equipped with deformable sleeve, can be incited somebody to action
Motor lead-out wire, which is pressed directly into sleeve, saves a connecting terminal, has reached the firm purpose of wiring, but this terminal plate
Mode of connection is special, not easy to operate, and anchor structure is complicated, and difficulty of processing is high.
The patent of 201656651 U of Chinese utility model patent CN discloses a kind of compact-sized motor wire-connecting board, should
Terminal plate is formed H-shaped vacancy, is facilitated the extraction of motor lead-out wire by the vacant position hollow out between six binding posts.But by
Excessively compact in terminal plate, the spacing between lead-out wire is too short, is easy to happen contact short circuit, there is very big security risk.
The patent of 102931758 A of Chinese utility model patent CN discloses a kind of electric machine wire connector, the termination
By the step of changing terminal plate structure, having subtracted crimping OT connector lug, the OT connector lug of access feed cable is eliminated, is saved
Zero widget, quick for installation, save the cost.But the OT connector lug of motor lead-out wire relies only on nut compression, structure is loosely
It leans on, cable skids off risk, and there are security risks.
Summary of the invention
In view of the above technical problems existing in the prior art, one of the purpose of this utility model is to provide one kind detachably more
The motor wire-connecting board of changing-over terminal.Pre-buried one possesses two or more different size threaded holes in the terminal plate pedestal
