Abstract
Disclosed is a modular speed sensor framework, which comprises a soft magnet, a permanent magnet, connecting pieces and a plastic framework, wherein the soft magnet and the permanent magnet are mutually connected and are integrally injection-molded in the plastic framework; the front end of the soft magnet protrudes from the bottom of the plastic framework; the connecting pieces are respectively arranged on two sides of the plastic framework and are integrally injection-molded and fixed with the plastic framework; a coil is arranged at one outer side, where the soft magnet is located, of the plastic framework; and both ends of the coil are respectively wound on the connecting pieces. Compared with the prior art, a magnetic circuit part is designed into an independent module so that the assembly process is simplified; the permanent magnet and the soft magnet are reliably connected together and injection-molded in the plastic framework, the assembly error of the magnetic circuit part is greatly reduced, and the consistency of the product performance is improved; and as the connecting pieces are also injection-molded in the plastic framework, the assembly error is reduced, the possibility of wire hanging and breaking when the coil is being wound on the connecting piece is reduced, the cost is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of speed probe, particularly a kind of modular speed probe skeleton.
Background technology
As shown in Figure 1, existing speed probe mainly comprises: soft magnet 1, coil 2, housing 3, plastic skeleton 4, permanent magnet 5, brace 6 and end cap 7; Plastic skeleton 4 is hollow structure, is provided with core of a cable 8 in the end cap 7.
The main installation step of existing speed probe is as follows: respectively soft magnet 1 and permanent magnet 5 are put in the plastic skeleton 4; Brace 6 is contained on the plastic skeleton 4; Around to plastic skeleton 4, simultaneously coil 2 two ends are respectively around the two ends of brace 6 with coil 2; Put in the housing 3, cover end cap 7.
In the above-mentioned steps, but housing 3 and also integral molded plastic moulding of end cap 7.
The Standard operation of existing speed probe is many, and because the rigging error that magnetic circuit part exists causes the consistance of properties of product bad; Because brace 6 is to be assembled on the plastic skeleton 4, the rigging error of existence causes having hanging wire and broken string at coil 2 around to brace 6 time, and rejection rate is higher.
Therefore, need especially a kind of modular speed probe skeleton, to solve the above-mentioned existing problem that exists.
The utility model content
The purpose of this utility model is to provide a kind of modular speed probe skeleton, for the deficiencies in the prior art, has simplified assembly process, has greatly lowered rigging error, has improved the consistance of properties of product, has lowered cost, has improved production efficiency.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind of modular speed probe skeleton, it is characterized in that, it comprises soft magnet, permanent magnet, brace and plastic skeleton, described soft magnet and permanent magnet be connected to each other and integrated injection molding in described plastic skeleton, the front end of described soft magnet protrudes the bottom of described plastic skeleton, described brace is arranged on the both sides of described plastic skeleton and fixes with described plastic skeleton integrated injection molding, the arranged outside of the plastic skeleton at described soft magnet place has coil, and the two ends of described coil are wrapped in respectively on the described brace.
In an embodiment of the present utility model, be provided with for the injecting hole of locating permanent magnet and brace at described plastic skeleton.
In an embodiment of the present utility model, be provided with a circular groove at an end of described soft magnet, described soft magnet is connected to each other by described circular groove and described permanent magnet.
Modular speed probe skeleton of the present utility model, compared with prior art, magnetic circuit part becomes separately a module, has simplified assembly process; Simultaneously, permanent magnet and soft magnet link together reliably, are injection-moulded in the plastic skeleton, and the magnetic circuit part rigging error lowers greatly, have improved the consistance of properties of product; Brace also is injection-moulded in the plastic skeleton, has reduced rigging error, also just reduced coil-winding on brace hanging wire and broken string may, lowered cost, improved production efficiency, realize the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
