In the embodiment shown in Fig. 5 a～Fig. 5 e, external connecting divides 233 with respect to mid portion 232, to be bent into 90 ° downwards, and restriction face G1 and external connecting are divided 233 parallel.Here, the minimum vertical height of upper space S1 is slightly larger than external connecting and divides 233 length, thereby make, this external connecting can be divided 233 along the direction of arrow terminal-connecting means 10 of packing into.
In Fig. 5 a, mark has locating surface L1 and locating surface L2, is separately positioned on the main part 11 of terminal-connecting means 10 and the terminal support parts 22 of coil rack 20.Locating surface L1 coordinates with locating surface L2, with the position of restriction terminal 23 upstream end sub-connecting devices 10, thereby the external connecting that can prevent terminal 23 divide 233 because of collision damaged.
In Fig. 5 a, coil rack 20 is along arrow direction, thereby divides 233 to be advanced in upper space S1 the external connecting of terminal 23.Fig. 5 b shows the state after this motion is completed.As shown in Figure 5 b, locating surface L1 and locating surface L2 contact, thereby have realized the restriction for the relative position between coil rack 20 and terminal-connecting means 10.Under locating surface L1 and the contacted state of locating surface L2, external connecting divides 233 near restriction face G1 or with G1, to contact, but can be not again to the direction of G1, move, thus can prevent external connecting divide 233 because of collision restriction face G1 damaged.This location safeguard procedures are particularly effective for manual installation.
In other embodiments of the invention, also can not have the location structure of similar locating surface L1 and locating surface L2, but when dividing 233 to touch restriction face G1, external connecting stops the movement of shaped framework coil 20, the perhaps setting by for automaton, installing, prevent that external connecting from dividing 233 to touch restriction face G1.
Alternatively, be provided with dividing plate 13 in upper space S1.In Fig. 5 b, it is 233 parallel that dividing plate 13 and external connecting are divided, and dividing plate 13 has with the external connecting of terminal 23 and divides 233 at quantity and equal slit of coupling in shape.That is to say, these slits equate with the number of terminal, width is slightly larger than diameter (circular cross section terminal) or the width (square cross section terminal) of terminal, length is slightly larger than the external connecting of terminal and divides 233, can be so that external connecting divides 233 along the direction of arrow in Fig. 5 a, to pass dividing plate 13.
In other embodiments of the invention, dividing plate 13 can be not divide 233 parallel with external connecting yet, but with an angle, but as long as the slit of dividing plate 13 along the opposite direction of Fig. 5 a direction of arrow externally projection and the external connecting on 233 planes, coupling part divide 233 to be complementary, namely this projection width is slightly larger than diameter (circular cross section terminal) or the width (square cross section terminal) of terminal, length is slightly larger than the external connecting of terminal and divides 233, makes external connecting divide 233 along the direction of arrow in Fig. 5 a, to pass dividing plate 13.
Due to the effect of slit, dividing plate 13 can prevent that to a certain extent dust and impurity from entering into the motor internal that coil rack 20 is installed, and in addition, dividing plate 13 also can play certain position-limiting action to terminal.
In Fig. 5 c, coil rack 20 moves along the direction of arrow in the figure, and it is 233 parallel that this direction and the external connecting of terminal 23 are divided.As shown in Figure 5 c, restriction face G1 is all parallel with the direction of motion shown in arrow with restriction face G2, and external connecting divides 233 can move in the gallery between restriction face G1 and restriction face G2.The width of this movable passageway and external connecting are divided 233 head width coupling, namely are slightly larger than diameter (circular cross section terminal) or the width (square cross section terminal) of terminal, thereby can prevent well entering of dust etc.
In the embodiment with locating surface L1 and locating surface L2, locating surface L2 contacts with locating surface L1, and along locating surface L1, moves down, and also can play the effect that the motion to terminal 23 limits.
As shown in Figure 5 c, be provided with alternatively dividing plate 14 in lower space S2.External connecting divides 233 along the direction of arrow, to move, and passes the perforation that is arranged at dividing plate 14.
Alternatively, the size of perforation and the head of terminal are complementary, that is, the minimum widith of perforation is slightly larger than the diameter (circular cross section terminal) of terminal or the width (square cross section terminal) of terminal at least, so that the head of terminal can pass this perforation.That is to say, the external connecting of the size of perforation and terminal 23 is divided 233 couplings, makes external connecting divide 233 can pass perforation.Because the Breadth Maximum of perforation can be slightly larger than or greater than the diameter (circular cross section terminal) of terminal or the width (square cross section terminal) of terminal, external connecting divides 233 can pass perforation with certain angle.
Preferably, external connecting divides 233 can vertically pass perforation.At this moment, for circular cross section terminal or square cross section terminal, perforation can be circular perforations or the square perforation that is complementary with it, thereby make external connecting divide 233 just can vertically pass perforation, can play better like this movement of terminal 23 is carried out spacing and prevented the effect that dust etc. enters.
In Fig. 5 d, the external connecting of terminal 23 divides 233 to move to as shown in Figure 5 c in lower space S2.
For the embodiment with dividing plate 14, external connecting divides 233 position to be participated in limiting by the support of dividing plate 14 for the mid portion 232 of terminal 23; , for the embodiment with dividing plate 13, also can be participated in limiting by the support of the one or more lower edge in the slit in dividing plate 13 for the mid portion 232 of terminal 23; Also can adopt other to limit mechanism.Limiting mechanism can act on respectively, also can jointly play position-limiting action.
, at the state shown in Fig. 5 d, the external connecting of terminal 23 can be divided 233 with the external plug (not shown), to be electrically connected to, and this external plug is fixedly connected on socket part 12.
Can only be to limit the variation of face G3 and corresponding lower space S2 due to the difference of terminal-connecting means shown in Figure 3 and terminal-connecting means shown in Figure 2, for Fig. 5 a～foregoing description of Fig. 5 d, be equally applicable to coil rack shown in Figure 4 is installed to the situation of terminal-connecting means shown in Figure 2.
In the embodiment according to shown in Figure 3, alternatively, external connecting divides 233 to move along direction shown in arrow in lower space S2.
In the embodiment with dividing plate 14, alternatively, the perforation on dividing plate 14 is extended on its Breadth Maximum direction, to form a perforated slot, thus can be so that external connecting divides 233 can be in this perforated slot along direction shown in arrow in Fig. 5 d, to move.
Alternatively, the locating surface L4 that is arranged on the locating surface L3 of main part 11 and is arranged on terminal support parts 22 is in contact with one another and relative sliding, with participate in the perpendicular direction of direction shown in arrow on carry out spacing to terminal 23.
Fig. 5 e shows the state after the movement of having carried out in Fig. 5 d.At this moment, because external connecting divides 233 to move a segment distance L, thereby for external plug provides additional space, can be in the socket part 12 larger sized external plug of access.
Fig. 6 a～Fig. 6 e shows stage by stage coil rack shown in Figure 4 is installed to the process of terminal-connecting means in accordance with another embodiment of the present invention.
As shown in Figure 6 a, with the structure difference shown in Fig. 3 and Fig. 5 a, be, restriction face G1 and locating surface L1 divide 233 bearing of trend to tilt with respect to the external connecting of terminal 23.Preferably, restriction face G1 is parallel with locating surface L1.
Be similar to shown in Fig. 5 a, along the direction of arrow, divide 233 to be advanced in the upper space S1 of terminal-connecting means 10 external connecting of terminal 23.The direction of arrow indication can be parallel with the mid portion 232 of terminal 23.Locating surface L1 coordinates with locating surface L2, with the position of restriction terminal 23 upstream end sub-connecting devices 10, thereby the external connecting that can prevent terminal 23 divide 233 because of collision damaged.
The state that Fig. 6 b shows motion in this Fig. 6 a after completing.As shown in Figure 6 b, locating surface L1 and locating surface L2 contact, thereby have realized the restriction for the relative position between coil rack 20 and terminal-connecting means 10.Under locating surface L1 and the contacted state of locating surface L2, external connecting divides 233 near restriction face G1 or with G1, to contact, but can be not again to the direction of G1, move, thus can prevent external connecting divide 233 because of collision restriction face G1 damaged.
