Abstract
The utility model discloses pressure line type commutator, including plastic substrate and make the commutation copper sheet of circumference arrangement in plastic substrate excircle, the medial surface of commutation copper sheet is provided with upper and lower hook implantation plastic substrate, it is characterised in that：The lateral surface of commutation copper sheet is smooth cylinder isometrical up and down, bonding wire crotch and bonding wire groove are not set on commutation copper sheet, the top connection wrapping post of commutation copper sheet, the cylindrical movable sleeve of wrapping post is provided with sphere small washer, the top of wrapping post is provided with threaded ring, and threaded ring screw thread is screwed at the top of plastic substrate on the cylindrical external screw thread being provided with.The utility model provides a kind of commutator of brand-new connection mode, is not required to spot welding or brazing mode and being conductively connected between commutator and wire can be achieved, easy to connect, ensures quality of connection.
Description
Technical field
It the utility model is related to a kind of improvement invention of commutator.
Background technology
The commutator of prior art, either Hooked reverser, tank commutator and flat commutator, itself and winding wire
Connection be that spot welding and soldering are included using welding manner, therefore the commutation copper sheet of commutator needs special setting bonding wire crotch
Or bonding wire groove, the consumptive material of commutation copper sheet is larger, and it is subjected to using welding equipment, and it is past to weld operation
Toward easily there is rosin joint, the row's of falling phenomenon, cause quality of connection unreliable, it is also necessary to be taken from commutator structure or welding procedure
Certain measure ensures.
The content of the invention
In view of the problem of currently known technology is present, the technical problems to be solved in the utility model is to be to provide one kind not
Need spot welding or brazing mode that being conductively connected between commutator and wire can be achieved, it is easy to connect, ensure the pressure of quality of connection
Wire type commutator.
The utility model is adopted the following technical scheme that to complete：
Pressure line type commutator, including plastic substrate and plastic substrate excircle make circumference arrangement commutation copper sheet, commutation
The medial surface of copper sheet is provided with upper and lower hook implantation plastic substrate, it is characterised in that：The lateral surface of commutation copper sheet is isometrical up and down
Smooth cylinder, do not set bonding wire crotch and bonding wire groove on commutation copper sheet, the top connection wrapping post of commutation copper sheet, wrapping post it is outer
Flexible move is arranged with sphere small washer, and the top of wrapping post is provided with threaded ring, and threaded ring screw thread is screwed in plastic substrate top
On the cylindrical external screw thread being provided with portion.
The spherical surface hill of sphere small washer is down against the top end face of commutation copper sheet.
The lower surface of threaded ring is provided with annular groove in the position of corresponding wrapping post.
After adopting the above technical scheme, the commutation copper sheet of commutator does not set bonding wire crotch and bonding wire groove, consumptive material simple in construction
It is few, cost is saved, the connection connected as compression mode between commutator and winding wire, rather than the company of spot welding or brazing mode
Connect, it is easy to connect, improve quality of connection.Operation principle is：By each terminal of coil around being connected to corresponding commutation copper sheet
After on the wrapping post that top is provided with, screw thread trim ring, now threaded ring can be by sphere small washer to terminal progress
Compress, in compaction process, sphere small washer can make adaptivity rotation, with the more preferable uniform pressure realized to all terminals
Tightly, so as to the quality of connection more preferably between guarantee wire and commutation copper sheet.
Brief description of the drawings
The utility model has the following drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment
As illustrated, pressure line type commutator of the present utility model, including plastic substrate 1 and make in the excircle of plastic substrate 1
The commutation copper sheet 6 of circumference arrangement, the medial surface of commutation copper sheet 6 are provided with upper and lower hook 7 implantation plastic substrate 1, commutation copper sheet 6
Lateral surface is smooth cylinder isometrical up and down, and bonding wire crotch and bonding wire groove are not set on commutation copper sheet 6（In the prior art, hook changes
Bonding wire crotch is provided with top to the commutation copper sheet of device, and the commutation copper sheet of tank commutator is provided with bonding wire groove on top, and plane
The commutation copper sheet of commutator, which has to set bonding wire crotch and also have, sets bonding wire groove）, the top connection wrapping post 5 of commutation copper sheet 6, wrapping post
5 cylindrical movable sleeve is provided with sphere small washer 3, and the spherical surface hill of sphere small washer 3 is down against the top end of commutation copper sheet 6
Face, the top of wrapping post 5 are provided with threaded ring 2, and the screw thread of threaded ring 2 is screwed in the cylindrical outer spiral shell being provided with the top of plastic substrate 1
On line 9, the lower surface of threaded ring 2 is provided with annular groove 8 in the position of corresponding wrapping post 5.
Above-mentioned pressure line type commutator, the termination process that is electrically connected with winding wire are：By the solderless wrapped connection of each terminal 4 of coil
After on the wrapping post 5 being provided with to the top of corresponding commutation copper sheet 6, screw thread trim ring 2, now threaded ring 2 can pass through sphere
Small washer 3 compresses to terminal 4, and in compaction process, sphere small washer 3 can make adaptivity rotation, to all wires
Joint 4 is uniformly compressed, and carrys out the more preferable quality of connection ensured between wire and commutation copper sheet.
