In some scenarios, the spacing between the terminal 4 and the end cap 12 may be equal to the thickness of the shield 3 in the arrangement direction of the terminal 4, the shield 3, and the end cap 12. In general, in the arrangement direction of the terminal 4, the shield 3 and the end cover 12, the thickness of the shield 3 is set to about 2mm to ensure the insulation effect between the terminal 4 and the end cover 12. In one embodiment, the insulating wire holder 2 is connected to the housing body 11, and the shield case 3 is connected to the end cap 12. In the assembly, the insulating wire holder 2 may be first assembled with the housing main body 11 and the shield cover 3 with the end cover 12, and then the housing main body 11 and the end cover 12 may be assembled.

In production, the main body part and the cover part can be of an integrally formed structure, or can be connected together through fasteners such as bolts. In addition, the housing 1 may be of an existing design, and this embodiment will not be described in detail.

As shown in fig. 2, in one embodiment, the insulating wire holder 2 includes an insulating base 21 and a plurality of insulating spacers 22, the insulating base 21 is connected to the housing 1, each insulating spacer 22 is sequentially disposed on the insulating base 21 at intervals, that is, each insulating spacer 22 is disposed on a surface of the insulating base 21 near the shielding case 3, and each insulating spacer 22 is sequentially disposed at intervals along a direction. In addition, an insulating space is formed between two adjacent insulating spacers 22; the shielding case 3 is arranged at one end of the insulating partition 22 away from the insulating base plate 21; the connection terminal 4 is disposed in the insulating space and between the insulating base plate 21 and the shield case 3. Two adjacent wiring terminals 4 can be separated through each insulating partition 22, short circuit between the adjacent wiring terminals 4 is effectively avoided, and electrical isolation between the adjacent wiring terminals 4 is achieved. The connection of the terminal 4 to the insulating holder 2 mainly means that the terminal 4 is disposed in the insulating space.

In this embodiment, "a plurality of" means greater than or equal to two, and the meaning of "a plurality of" in each embodiment of the present application is the same, and the subsequent embodiments are not described in detail. In addition, the side of the connection terminal 4 away from the insulating connection base 2 is the side of the connection terminal 4 away from the insulating base 21. Furthermore, a connection terminal 4 is usually arranged in an insulating space.

In one embodiment, the insulating base 21 may be a flat plate, and the insulating spacers 22 may be the same in size and shape, so that the difficulty in manufacturing the insulating wire holder 2 may be reduced. Of course, the size of each insulating spacer 22 may be different, and the size of each insulating spacer 22 may be different. In actual production, the shape and size of each insulating spacer 22 may be adaptively adjusted according to the size, shape, and other factors of the installation cavity. That is, the external shape of the insulating wire holder 2 may be adjusted according to the shape or size of the installation cavity, for example, refer to fig. 4 and 5, which are views of the insulating wire holder 2. In addition, the insulating wire holder 2 may be designed in the prior art, and this embodiment will not be described here too much.

In one embodiment, one end of the connection terminal 4 is located outside the insulation space, and the other end of the connection terminal 4 is located inside the insulation space. The part of the wiring terminal 4 located outside the insulation space can be electrically connected with an electric control element of the motor 10, and the part of the wiring terminal 4 located inside the insulation space is electrically connected with the cable 5; the cable 5 may extend out of the housing 1 for electrical connection with a corresponding power source external to the motor 10. The housing 1 is provided with corresponding wire holes, so that the cable 5 can extend out of the housing 1 from the inside of the installation cavity.

In addition, the region where both the cable 5 and the terminal 4 are connected is also located in the insulating space, and the connection region of the cable 5 and the terminal 4 is also located between the insulating base 21 and the shield 3. In addition, the outer side of the cable 5 is generally coated with an insulating layer, and when the cable is connected to the connection terminal 4, the insulating layer at one end of the cable 5 needs to be stripped, so as to realize electrical connection between the cable 5 and the connection terminal 4. At this time, the portion of the cable 5 for connecting with the connection terminal 4, which is not covered with the insulating layer (defining the portion as the first portion), is also disposed in the insulating space, and the first portion is also disposed between the insulating base 21 and the shield case 3.

In addition, the number of the connection terminals 4 may be set according to actual needs, for example, when the motor 10 is a three-phase motor, the number of the connection terminals 4 may be three, and the three connection terminals 4 are electrically connected with the power supply through corresponding cables 5 respectively. Of course, when the motor 10 is a three-phase motor, the number of the connection terminals 4 may be more than three, and in this case, other connection terminals 4 than the connection terminals 4 for connecting the three-phase cables 5 may be electrical connections for other functions of the motor 10, such as for grounding, among the connection terminals 4.

In a practical scenario, the connection terminal 4 and/or the cable 5 (the cable 5 is electrically connected to the connection terminal 4) may protrude toward one side of the insulating shielding plate 31 due to installation or subsequent stress and vibration, wherein the portion protruding the insulating space is easily shorted. In response to this problem, as shown in fig. 6, in one embodiment, a plurality of insulation shaping grooves 30 are provided on the shield case 3, and each insulation shaping groove 30 is used to accommodate the connection terminal 4 and/or the cable 5 connected to the connection terminal 4. In particular, a portion of the insulation-molding groove 30 that is opposite to an insulation space, from which the connection terminal 4 and/or the cable 5 protrude, may be accommodated in the insulation-molding groove 30 opposite to the insulation space. At this time, the portion of the connection terminal 4 and/or the cable 5 protruding from the insulation space can be electrically separated from surrounding elements by the side wall of the insulation finishing groove 30, thereby improving the insulation effect. Meanwhile, the wiring terminal 4 and/or the cable 5 are guided through the side wall of the insulation shaping groove 30, so that the shaping effect on the wiring terminal 4 and/or the cable 5 is achieved, and interference among phases of the three-phase motor can be effectively avoided.

In addition, after the motor 10 is assembled, the arrangement direction of each insulation groove 30 is the same as the arrangement direction of each insulation space. The number of the insulation-shaping grooves 30 and the number of the insulation spaces may be the same, so that each of the connection terminals 4 and/or the portions of the cables 5 protruding from the insulation spaces may be accommodated in one insulation-shaping groove 30, thereby achieving a better insulation-shaping effect. Further, the width of the insulation finishing groove 30 may be equal to the width of the insulation space.

After assembly, the insulating shield 31 may enclose the cable 5 and the terminal block 4 within an insulating space. In addition, the insulating shield plate 31 may be a flat plate structure. Further, an insulation shaping groove 30 is provided on the insulation shield plate 31, and the insulation shaping groove 30 is located on a surface of the insulation shield plate 31 close to the insulation base plate 21.

In addition, the thickness of the shield case 3 may refer to a distance between a surface of the insulating barrier 32 facing away from the insulating barrier 31 to a surface of the insulating barrier 31 facing away from the insulating barrier 32.

After assembly, the arrangement direction of each insulating barrier 32 is identical to the arrangement direction of each insulating barrier 22, and one insulating barrier 32 is opposite to one insulating barrier 22. In addition, after assembly, the portion of the connection terminal 4 and/or the cable 5 protruding from the insulation space can be separated from surrounding elements by the insulation barrier 32, thereby improving the insulation effect. In addition, an insulating barrier 31 may interfere with an insulating barrier 22 after assembly.

In addition, the second mounting hole is actually provided in the end cap 12.

In the axial direction of the first mounting hole 331, the height of the insulating column 33 is larger than the thickness dimension of the insulating shield plate 31, so that the strength of the shield can 3 can be improved, and the shield can 3 is effectively prevented from being pressed by the connecting piece.
