Description

  The present invention relates to an auxiliary cap mounting jig used when performing an operation of covering a plurality of electric wires of a motor with an auxiliary cap having a tapered tip.

In recent years, miniaturization of motors mounted on automobiles has been promoted. Therefore, it is required to reduce the lead wire portion connected to the terminals constituting the motor.
In general, a lead wire portion connected to a terminal is used by being inserted into a cylindrical insulating sleeve for insulation (see Patent Document 1). When inserting the lead wire portion into the insulating sleeve, first, as shown in FIG. 12, an auxiliary cap 8 having a tapered tip is put on the lead wire portion 7 in which a plurality of electric wires 71 are bundled. Then, as shown in FIGS. 13 and 14, the lead wire portion 7 is inserted into the insulating sleeve 9 using the auxiliary cap 8 as a guide.

Therefore, in order to reduce the bundle diameter of the lead wire portion, it is necessary to reduce the diameter of the insulating sleeve into which the lead wire portion is inserted. Accordingly, it is necessary to reduce the outer diameter of the auxiliary cap. Further, as the outer diameter of the auxiliary cap is reduced, the inner diameter is also reduced. When the lead wire portion is inserted into the auxiliary cap, the difference between the inner diameter of the auxiliary cap and the bundle diameter of the lead wire portion becomes small, making insertion difficult. Therefore, if the inner diameter of the auxiliary cap is further reduced, the operation of covering the lead wire portion with the auxiliary cap becomes more difficult, and the operation time may be further increased.
For this reason, there is a need for a method and means that can easily perform the operation of covering the lead wire portion with the auxiliary cap and can reduce the operation time.

  As shown in FIGS. 1 and 2, the cap mounting table 43 is provided with a cap mounting portion 431 for mounting the auxiliary cap 8. The height of the cap mounting portion 431 in the cap mounting base 43 is such that the guide portion 2 (first piece portion 21) is positioned at the lowest point of the slidable range, that is, the center of the connecting fulcrum portion 23 in the guide portion 2. When C is located at the reference position P1 (see FIG. 2), the axis center of the auxiliary cap 8 placed on the cap placement portion 431 and the axis center of the guide hole 3 are set to coincide with each other.

Next, the operation | work which covers the auxiliary | assistant cap 8 on the lead wire part 7 using the auxiliary | assistant cap mounting jig | tool 1 of this example is demonstrated using FIGS.
First, as shown in FIG. 6, the auxiliary cap 8 is placed on the cap placement portion 431 of the cap placement base 43 and inserted into the cap insertion portion 31 of the guide hole 3. At this time, the rear end 802 of the auxiliary cap 8 is placed and inserted toward the second opening end 302 of the guide hole 3. Thereby, the auxiliary cap 8 can be fixed in a state where the cap opening portion 81 is opened toward the wire insertion portion 32.

  Next, as shown in FIG. 7, the lead wire portion 7 including a plurality of electric wires 71 is inserted from the insertion port 321 of the wire insertion portion 32. At this time, since the inner diameter of the insertion port 321 is larger than the cap opening portion 81 into which the lead wire portion 7 is finally inserted, the lead wire portion 7 is inserted even if the plurality of electric wires 71 are not properly bundled. It can be easily inserted from the mouth 321.

  Next, as shown in FIG. 8, the lead wire portion 7 is moved from the insertion port 321 toward the throttle port 322. At this time, since the wire insertion portion 32 has a taper shape in which the inner diameter gradually decreases from the insertion port 321 toward the throttle port 322, the bundle diameter of the lead wire portion 7 is the taper shape of the wire insertion portion 32. It is gradually reduced as it is guided. Then, by moving the lead wire portion 7 to the throttle port 322, the bundle diameter of the lead wire portion 7 becomes substantially the same as the inner diameter of the throttle port 322. That is, the inner diameter of the cap opening 81 can be made smaller.

Next, as shown in FIG. 9, the lead wire portion 7 is moved from the aperture 322 to the cap insertion portion 31 via the connecting portion 33. Then, the lead wire portion 7 whose bundle diameter is smaller than the inner diameter of the cap opening portion 81 is inserted into the cap opening portion 81 opened toward the wire insertion portion 32.
Thus, the auxiliary cap 8 is put on the lead wire portion 7.
In addition, the operation | work which inserts the auxiliary | assistant cap 8 in the cap insertion part 31 and the operation | work which inserts the lead wire part 7 in the wire insertion part 32 can also be performed reversely, and can also be performed simultaneously.

  Next, as shown in FIG. 10, the first piece portion 21 is slid upward while the lead wire portion 7 covered with the auxiliary cap 8 is held in the guide hole 3. And when the center C of the connection fulcrum part 23 is located above the regulation position P2, the second piece 22 is released from the urging by the regulation part 42, and the center C of the connection fulcrum part 23 is the center of the rotation axis. And rotate in the A direction (see FIG. 5). Thereby, both the piece parts 21 and 22 switch from a closed state to an open state.

Then, as shown in FIG. 11, the lead wire portion 7 is taken out from the guide hole 3 of the guide portion 2. Thereafter, when the force holding the first piece 21 upward is removed, the first piece 21 returns to its original position due to its own weight. At the same time, the second piece 22 returns to the state of being urged by the restricting portion 42. That is, the center C of the connection fulcrum part 23 in the guide part 2 returns to the reference position P1 (see FIG. 2). And both the piece parts 21 and 22 will be in a closed state again.
As a result, the next operation can be performed.

  Further, as shown in FIGS. 13 and 14, the lead wire portion 7 covered with the auxiliary cap 8 is inserted into the cylindrical insulating sleeve 9 using the auxiliary cap 8 as a guide.

Next, the effect in the auxiliary cap mounting jig 1 of this example is demonstrated.
In the auxiliary cap mounting jig 1 of this example, the wire insertion portion 32 of the guide hole 3 has an insertion port 321 into which the lead wire portion 7 is inserted, and the insertion port 321 finally assists the insertion of the electric wire 7. The inner diameter is larger than the cap opening 81 of the cap 8. Therefore, the lead wire portion 7 can be easily inserted from the insertion port 321 even if the plurality of electric wires 71 constituting the lead wire portion 7 are not properly bundled.

  Further, the wire insertion portion 32 has a tapered shape in which the inner diameter gradually decreases from the insertion port 321 toward the throttle port 322. Therefore, as the lead wire portion 7 is moved from the insertion port 321 toward the throttle port 322, the bundle diameter of the lead wire portion 7 is guided by the taper shape of the wire insertion portion 32 and gradually decreases. Further, by moving the lead wire portion 7 to the throttle port 322, the bundle diameter of the lead wire portion 7 can be made smaller than the inner diameter of the cap opening portion 81. As a result, the lead wire portion 7 can be easily inserted into the cap opening portion 81. That is, the auxiliary cap 8 can be easily put on the lead wire portion 7.

  The restricting portion 42 restricts the two pieces 21 and 22 to be closed when the center C of the connecting fulcrum 23 in the guide portion 2 is positioned below the restricting position P2 (see FIG. 2). When the center C of the connecting fulcrum 23 is positioned above the restriction position P2 (see FIG. 5), the restriction can be released so that the two pieces 21 and 22 are opened. Therefore, when both the pieces 21 and 22 are closed, the lead wire portion 7 is covered with the auxiliary cap 8 and the lead wire portion 7 is slid upward together with the guide portion 2 so that the pieces 21 and 22 are , Switching from the closed state to the open state. Then, the lead wire portion 7 can be taken out from the guide hole 3 of the guide portion 2. Thereby, a series of operations of covering the lead wire portion 7 with the auxiliary cap 8 and taking out from the auxiliary cap mounting jig 1 can be performed efficiently and quickly.

  Further, in this example, the guide hole 3 has the rear end portion 802 of the auxiliary cap 8 on the first opening end portion 301 side opposite to the second opening end portion 302 provided with the insertion port 321 of the wire insertion portion 32. An insertable cap insertion portion 31 is provided, and a throttle port 322 of the wire insertion portion 32 is connected to the cap insertion portion 31. Therefore, the auxiliary cap 8 can be fixed in a state where the cap opening 81 of the auxiliary cap 8 is opened toward the wire insertion portion 32. Then, the lead wire portion 7 whose bundle diameter is smaller than the inner diameter of the cap opening portion 81 can be easily inserted into the cap opening portion 81.

  In addition, a cap mounting table 43 having a cap mounting portion 431 for mounting the auxiliary cap 8 is disposed adjacent to the guide portion 2. And the height of the cap mounting part 431 in the cap mounting base 43 is placed on the cap mounting part 431 when the center C of the connecting fulcrum part 23 in the guide part 2 is located at the reference position P1 (see FIG. 2). The axial center of the placed auxiliary cap 8 and the axial center of the guide hole 3 are set to coincide with each other. Therefore, by placing the auxiliary cap 8 on the cap placement portion 431, the auxiliary cap 8 can be easily inserted into the cap insertion portion 31 and can be firmly fixed in the cap insertion portion 31.

  Thus, by using the auxiliary cap mounting jig of this example, the operation of covering the auxiliary cap on the lead wire portion made of a plurality of electric wires can be performed efficiently and easily. And the time which the said operation | work requires can be shortened.
