Angle, such fastening effect are more preferable.This is due to that three gusset pieces 30 are placed side by side in itself, can naturally enough leave two
Gap.Have benefited from the ingehious design of the shape of gusset piece 30, gap length sets the 3rd fastener 52 enough.Enable space by
Utilize very comprehensive.
The fixed part 401 of first tension disc 40 can be also bonded with the center section of gusset piece 30 just, so be enabled to
Fastening effect between gusset piece 30 and base 10 is more preferable, it is not easy to loosens.
For another the first tension disc 40 (the first tension disc 40 of fixed part 401 up in Fig. 2), its fixed part
401 are directly bonded and are fixedly connected with insulation board 11, can be connected using the in general bolt of such as the 3rd fastener 52, very
And can also directly be bonded in insulation board 11, and prevent that pigtail splice from loosening to be better achieved, preferably using bolt
Completion is fixedly connected.
Further, it is also possible to insulation board 11 to should first tension disc 40 the part of position installed of fixed part 401
Open up deep gouge so that it after fixed part 401 is arranged in deep gouge, can be connected with insulation board 11 more firm, and then for drawing
The clamping action of wire terminal and gusset piece 30 is also more firm.
Particularly, the overlying relation in the locking portion 402 of two the first tension discs 40 can also exchange, only need to be fixation
The height of the vertical portion in portion 401, which is made, to be adapted.
Fig. 5 and Fig. 6 are refer to, except the first tension disc 40 mentioned above, the first tension disc 40 of the present utility model is also
It can be a kind of such structure：
The quantity of first tension disc 40 is similarly two, and each first tension disc 40 has three connecting holes.Then, three
Three the first fasteners 50 used in coupling wire terminal are respectively arranged at three connecting holes of one of them the first tension disc 40, and three
Three the second fasteners 51 used in coupling wire terminal are respectively arranged at three connecting holes of another the first tension disc 40.
By a kind of such structure, the first tension disc 40, which equally realizes, is bound up on three-phase pigtail splice in X-direction
Together.
It is pointed out that in the first tension disc 40 of structure as use, per the corresponding to coupling wire terminal
The quantity of two tension discs 41 is two, in order to cause there is phase between the first fastener 50 and the second fastener 51 in the Y direction
Mutually limitation, to reach the purpose for improving the fastening effect for pigtail splice.
A part for pigtail splice and gusset piece 30 is clamped by two the second tension discs 41, and the first tension disc 40 is arranged at
The top of second tension disc 41 of top.
And the center section of three gusset pieces 30 is then pushed down by a fixed plate 43, and realized and insulation board 11 by bolt
Compression.The set-up mode of bolt is identical with the mode of the 3rd fastener 52.
Fig. 7 is refer to, the utility model also provides the first line ball of another structure on the basis of Fig. 5 scheme
Plate 40：
First tension disc 40 is one piece of whole plate, and array distribution has six connecting holes on the first tension disc 40.Per phase terminal
Corresponding two connecting holes of joint, it is two connecting holes of corresponding Y-direction in more detail.Per first used in coupling wire terminal
Fastener 50 is disposed therein a connecting hole, and the second fastener 51 used is arranged at another connecting hole.
In this way, the first tension disc 40 can not only realize the function of the first tension disc 40 in Fig. 5, moreover it is possible to a certain extent
Play a part of the second tension disc 41.Other structures can refer to the motor down-lead anti-loose structure 100 shown in Fig. 5 and Fig. 6.
First tension disc 40 of three kinds of structures of the present utility model can be combined with each other in the case where not conflicting,
Make it that overall structure is more compact and firm.
Found after situation about even being burnt to pigtail splice overtemperature is studied, mainly the fixture pine of pigtail splice
Take off and cause pigtail splice no longer firm.The motor down-lead anti-loose structure 100 of the present embodiment, pass through the first tension disc 40, second
Pigtail splice, gusset piece 30 and base 10 are securely attached together by tension disc 41 from both direction, and whole as one
Body, reduces the vibration of single-phase pigtail splice connection, and then reduces the possibility of loosened fastener.Have benefited from the shape of gusset piece 30
Shape design, the connection of gusset piece 30 and insulation board 11 is also very firm, this allow for gusset piece 30 for connect motor around
During group, the vibration of connecting portion can be also reduced, especially for first with fixed part 401 and the locking structure of portion 402
For the scheme of tension disc 40, because mutually suitable with the shape of gusset piece 30, the reduction for vibration can do better.
By such motor down-lead anti-loose structure 100, pigtail splice can be avoided to be released due to the vibration of motor, entered
And prevent pigtail splice overtemperature or burn, so as to ensure the reliability service of motor.Reliable overall structure so that even if
Be traction electric machine at work, pigtail splice can also be kept in violent vibration with the electrical connection of winding, fool proof practicality.
Embodiment 2
Fig. 8 is refer to, present embodiments provides the motor down-lead in a kind of motor, including electric machine stand 200 and embodiment 1
Anti-loose structure 100.
Specifically, motor down-lead anti-loose structure 100 is arranged at electric machine stand 200, one end of gusset piece 30 and motor around
Group connection, other end are connected with single-phase pigtail splice.
More it is completely that motor includes terminal box, terminal box includes housing 211 and backing plate 213, and (backing plate 213 is in Fig. 1
Have shown that), motor down-lead anti-loose structure 100 is arranged at backing plate 213 and positioned at the inside of housing 211, backing plate 213 and electric machine stand
