Abstract
The utility model discloses an insulation sleeve of an alternating-current generator. The technical problem to be solved by the utility model is to provide the insulation sleeve of the alternating-current generator, which is unnecessary to be fixed through a nut when being fixed on a motor housing. The insulation sleeve of the alternating-current generator disclosed by the utility model comprises an insulation sleeve body; a lug boss is arranged on the outside surface at the outer end of the insulation sleeve body; at least one elastic protruding block is also arranged on the outside surface at the inner end of the insulation sleeve body; and a clamping groove is formed between the lug boss and the elastic protruding block. The insulation sleeve of the alternating-current generator provided with the elastic protruding block can be pressed into the motor housing directly through extrusion force; after the elastic protruding block is pressed into the motor housing, the motor housing is clamped in the clamping groove; the insulation sleeve of the alternating-current generator is fixed on the motor housing and is unnecessary to be fixed through the nut; materials and the cost can be saved; and the working time for assembling the motor is shortened.
Description
Technical field
The utility model relates to a kind of alternating current generator insulating case.
Background technology
Insulating case is the part of alternating current generator; dynamo current is drawn motor housing by generator B terminal; and motor housing is equivalent to ground connection; it is the negative pole of generator; B terminal is the positive pole of generator, for preventing that B terminal from contacting and being short-circuited with generator casing, by B terminal wrapped with insulation; the part that this insulating material is made is called insulating case, and insulating case plays the effect of the contact point of protection B terminal and car load wire harness simultaneously.
In prior art, alternating current generator insulating case mostly is the cylindrical structural that insulating material is made, and adopts nut to coordinate insulating case is pressed abd fixed on motor housing with B terminal screw rod; When car load wire harness is connected with B terminal, lug plate is enclosed within on B terminal screw rod, by another nut, lug plate is fixed on B terminal screw rod again, so not only caused nut to reuse, waste material and cost, and when being fixed the nut of insulating case, caused the waste of operation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of alternating current generator insulating case, while being fixed on motor housing, does not need to fix by nut.
The utility model solves the alternating current generator insulating case that its technical problem adopts, comprise insulating case body, the boss arranging on the outer surface of described insulating case body outer end, on the outer surface of described insulating case body the inner, be also provided with at least one elastic projection, between described boss and described elastic projection, form buckling groove.
Further, described elastic projection is inverted triangle structure.
Further, the material of described elastic projection is elastoplast.
The beneficial effects of the utility model are: can directly by extruding force, the alternating current generator insulating case that is provided with elastic projection be pressed into motor housing, when elastic projection is pressed into after motor housing, motor housing is stuck in buckling groove, described alternating current generator insulating case is just fixed on motor housing, do not need to fix by nut, can save material and cost, and shorten the activity time of assembling motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, indicate: 1-insulating case body, 2-boss, 21-boss side surfaces, 3-elastic projection, 31-projection side, 4-buckling groove.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, alternating current generator insulating case of the present utility model, comprise insulating case body 1, the boss 2 arranging on the outer surface of described insulating case body 1 outer end, on the outer surface of described insulating case body 1 the inner, be also provided with at least one elastic projection 3, between described boss 2 and described elastic projection 3, form buckling groove 4.The inner refers to that one end that insulating case body 1 inserts motor housing, and outer end refers to that insulating case body 1 does not insert that one end of motor housing.Described elastic projection 3 can only have one, but better for fixed effect, and a plurality of described elastic projections 3 can be set on described insulating case body 1.The size that is provided with the alternating current generator insulating case of elastic projection 3 is greater than motor housing for the size in its hole of offering, under certain External Force Acting, when described alternating current generator insulating case is pressed into motor housing, under extruding force effect, elastic projection 3 can dwindle in distortion, described alternating current generator insulating case can be pressed into motor housing, when elastic projection 3 is pressed into after motor housing, the shape of elastic projection 3 is recovered, motor housing is stuck in buckling groove 4, boss side surfaces 21 towards described elastic projection 3 contacts with the outer surface of motor housing, projection side 31 towards described boss 2 contacts with the inner surface of motor housing, described alternating current generator insulating case is just fixed on motor housing, do not need to fix by nut.
In order to be more easily pressed into motor housing, described elastic projection 3 is inverted triangle structure.The thickness of the elastic projection 3 of inverted triangle structure is the thickest near described boss 2 ends, the thinnest away from described boss 2 ends.
Described elastic projection 3 can be made with metallic spring, also can make with elastoplast.For easy to process, improve the insulation property of alternating current generator insulating case simultaneously, optimal way is that described elastic projection 3 is made by elastoplast.
Claims (3)
1. alternating current generator insulating case, the boss (2) that comprise insulating case body (1), arranges on the outer surface of described insulating case body (1) outer end, it is characterized in that: on the inner outer surface of described insulating case body (1), be also provided with at least one elastic projection (3), between described boss (2) and described elastic projection (3), form buckling groove (4).
2. alternating current generator insulating case as claimed in claim 1, is characterized in that: described elastic projection (3) is inverted triangle structure.
3. alternating current generator insulating case as claimed in claim 1 or 2, is characterized in that: the material of described elastic projection (3) is elastoplast.
