In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 4 in combination, an assembling structure for assembling an insulating sheath 1 with a stator frame 2 includes: the bracket 3 is arranged on the stator framework 2; the supporting column 4 is arranged on the insulating sheath 1; two adjacent brackets 3 enclose an assembly groove 5, and the support column 4 is arranged in the assembly groove 5; be equipped with limit structure 6 in the assembly groove 5, limit structure 6 is used for keeping support column 4 in assembly groove 5, prevents support column 4 drunkenness.
In the prior art, after the insulating sheath and the stator framework are pre-positioned through the supporting column and the support, the positioning column and the positioning hole are used for precisely positioning, but the positioning in the horizontal direction can only be realized no matter the supporting column and the support or the positioning column and the positioning hole are used, and the insulating sheath and the stator framework are not axially maintained and fixed after being installed. When the stator is injected, the insulating sheath is easily axially moved under the impact of high-pressure high-speed plastic package materials, and once the axial movement occurs, the position precision of the contact pin is influenced. In order to prevent the axial float of insulating sheath, add limit structure 6 in this embodiment, limit structure 6 sets up in support 3 and support column 4's complex assembly groove 5, and support column 4 installs back in assembly groove 5, and limit structure 6 is fixed with it and is kept in the inslot, and support column 4 can't the axial float to guarantee the guard action of insulating sheath 1 to the contact pin. The present embodiment makes full use of the existing structure of the stator frame 2 and the insulating sheath 1, and the technical effect of preventing the movement of the supporting column 4 can be realized only by adding the limiting structure 6.
On the other hand, in the embodiment, the fine positioning of the insulating sheath 1 and the stator framework 2 is completed only through the supporting columns 4 and the support 3, and positioning columns and positioning holes do not need to be additionally arranged, so that the structures of the insulating sheath 1 and the stator framework 2 are simplified, and the material cost and the processing difficulty are reduced; the support column 4 is big with 3 sizes of support, easily differentiates, can effectively reduce insulating sheath 1 and stator skeleton 2's the location degree of difficulty, improves both assembly efficiency.
In this embodiment, the limiting structure 6 includes a bracket protrusion 7, and the bracket protrusion 7 is disposed on the bracket 3, and/or the limiting structure 6 includes a supporting column protrusion 8, and the supporting column protrusion 8 is disposed on the supporting column 4.
In this embodiment, assembly groove 5 is enclosed by two adjacent supports 3 on stator skeleton 2, and after support column 4 was installed in assembly groove 5, adopted the limit structure 6 of protruding structure, can be convenient with support column 4 fixed with assembly groove 5, protruding structure also be convenient for support column 4's installation and dismantlement. The limiting structure 6 can be a support bump 7 only arranged on the support 3, the support bump 7 is in interference fit with the support column 4, and the axial movement of the support column 4 is limited by axial friction. Similarly, the limiting structure 6 may also be a supporting column protrusion 8 only arranged on the supporting column 4, the supporting column protrusion 8 is in interference fit with the assembling groove 5, and the axial movement of the supporting column 4 is limited by axial friction. Further, limit structure 6 can be simultaneously including setting up support arch 7 on support 3 and the support column arch 8 of setting on support column 4, and support arch 7 and the protruding 8 interference fit of support column restrict the axial float of support column 4 through support arch 7 to the protruding 8 pressure of support column.
In this embodiment, the number of the support protrusions 7 is at least two, the at least two support protrusions 7 are symmetrically arranged on the side surfaces of the two supports 3 which enclose the assembly groove 5, the at least two support protrusions 7 face the supporting column 4, the supporting column 4 is installed behind the assembly groove 5, and the supporting column 4 is limited at the center of the assembly groove 5 by the at least two support protrusions 7.
The number of the supporting column protrusions 8 can be at least two, the at least two supporting column protrusions 8 are symmetrically arranged on two opposite side surfaces of the supporting column 4, the at least two supporting column protrusions 8 face the two supports 3 which are enclosed into the assembling groove 5, the supporting column 4 is installed behind the assembling groove 5, and the supporting column 4 is limited in the center of the assembling groove 5 by the at least two supporting column protrusions 8.
The support bump 7 and the support column bump 8 of this embodiment are the setting in pairs, because the orientation that support 3 need assemble support column 4 in this embodiment, in the installation and after the installation can be guaranteed to the support bump 7 or the support column bump 8 that set up in pairs, insulating sheath 1 and stator skeleton 2's the accurate cooperation of circumference.
In this embodiment, the support protrusions 7 are at least one of semi-circular protrusions and double-slope protrusions, and/or the support protrusion 8 is at least one of semi-circular protrusions and double-slope protrusions. By adopting the semicircular bulge or the double-inclined-plane bulge, the resistance of the support column 4 in assembly with the assembly groove 5 is small, the support column can be assembled and disassembled for many times, and the actual production requirement can be met.
In this embodiment, the end of the support column 4 contacts the bottom of the fitting groove 5 to support the insulating sheath 1. The bottom of the assembly groove 5 and the limiting structure 6 can form an upper-lower bidirectional limiting for the supporting column 4. Meanwhile, the support column 4 can maintain the original support function.
In the injection molding process, since the high-pressure and high-speed molding compound is diffused from the inside in the radial direction, the molding compound generates a radially inward extrusion force on the insulating sheath 1, which causes the insulating sheath 1 to deflect radially inward, and once the deflection occurs, the supporting column of the insulating sheath 1 may interfere with the enameled wire of the stator winding, and at the same time, the pin may deflect. In order to solve the problem in actual production, a shaping link is added after an injection molding process, and the deviation of the insulating sheath 1 is corrected manually.
In response to this problem, in the present embodiment, the bracket 3 is provided with the bead 9, the bead 9 is provided on the side of the bracket 3 close to the axis of the stator frame 2, and the bead 9 is used to prevent the support column 4 from shifting radially toward the axis of the stator frame 2. The arrangement of the protective edge 9 can effectively offset the radial extrusion force borne by the insulating sheath 1, prevent the radial deviation of the insulating sheath 1 and save the time and labor waste of the shaping link.
The assembly structure of this embodiment's insulating sheath 1 and stator skeleton 2 assembly are firm, prevent effectively that insulating sheath 1 from drunkenness from top to bottom, can be better play fixed contact pin protection solder joint and the effect of wiring board location. The protective edge 9 can effectively offset the radial extrusion force on the insulating sheath 1, so that the radial offset of the insulating sheath 1 is prevented, and the waste of the shaping link is saved.
