Abstract
The utility model discloses a motor-dedicated wire lead sheath, which comprises a metal sleeve (1); wherein, the tail of the metal sleeve (1) is of a bottom plate (2); and the metal sleeve (1) is sleeved by a plastic sleeve (3) the outer surface of which is provided with a screw thread (7). Compared with the prior art, the plastic sleeve is added on the outer surface of the metal sleeve by the method of injection molding, the outer surface of the plastic sleeve is provided with the screw thread, the structure is simple, the production and processing are easy, the cost is low, the precision is high, and compared with the metal sheath, the water-proof and anti-corrosion properties of the plastic sleeve are better.
Description
One, technical field
The utility model relates generally to the lead wire sheath that a kind of motor is used.
Two, background technology
Be connecting coil winding and external power source, motor down-lead enters motor internal by the hole that is located on the motor housing.The end that goes between connects winding, and an end connects external power source.But the wire hole on the motor housing can cause motor component to be exposed in the bad environment, Ru Shui, oil, dust.For anti-sealing, wet goods enter motor internal from wire hole effectively, the applicant is 200720053394.2 in the patent No., patent name has been for disclosing a kind of lead wire sheath a in " a kind of motor lead wire sheath ", the wire hole c position outer surface of its motor housing b is provided with a boss d, forming hollow pipe in the middle of the boss d is communicated with wire hole c, boss d is installed in lead wire sheath a the inside, motor down-lead e passes boss d and lead wire sheath a, motor down-lead e one end connects the motor internal winding, and the other end stretches out motor and connects power supply outward.The end that lead wire sheath a contacts with casing b has a base plate f, and the bottom surface of base plate f is adjacent on casing b surface, and there are two salient point g base plate f bottom surface, and there are two location hole h on described wire hole c next door, but described salient point g assembly is in location hole h.Described lead wire sheath a is made of metal, and its outer surface is provided with the wall scroll connecting thread, and lead wire sheath a is connected with the threaded one end of flexible pipe j, and motor down-lead e is connected with power supply with flexible pipe j by lead wire sheath a.
But still there is following problem in above-mentioned lead wire sheath: because lead wire sheath is the metal tube of thin-walled, machining screw is very difficult on the metal tube surface of thin-walled, and low precision, and the metal tube easy deformation.
Three, utility model content
The lead wire sheath that the utility model provides a kind of and produced easily, cost is low, precision is higher.
The utility model is to realize by following technical scheme:
A kind of motor lead wire sheath comprises metal sleeve, and the tail end of metal sleeve forms base plate, and described metal sleeve outside is set with plastic casing-pipe, and the plastic casing-pipe outer surface is provided with screw thread.
Compared with prior art, the utility model has following advantage: described plastic casing-pipe adds by injection molding way and is located at the metal sleeve outer surface, the plastic casing-pipe outer surface is provided with screw thread, simple in structure, production and processing is easy, and cost is low, the precision height, compare with metallic sheath, the waterproof anti-corrosion of plastic casing-pipe is stronger.
Above-mentioned described plastic casing-pipe is directly injection-moulded on the metal sleeve, has formed the extension injection molded layers at the metal sleeve inner surface, and it is more solid and reliable that plastic casing-pipe is connected with metal sleeve.
The end that above-mentioned described metal sleeve is connected with base plate is provided with protruding rank, structural strength that can the reinforcement metal sleeve pipe.
The bottom surface of above-mentioned described base plate is provided with two salient points, the base plate of the tail end of metal sleeve is welded on the surface of motor housing, and the line outlet of motor communicates with metal sleeve, and the lead-in wire of motor passes metal sleeve, one end connects the motor internal coil windings, and the other end stretches out motor and connects power supply outward.
The surface of above-mentioned described metal sleeve is provided with through hole, extends injection molded layers and is filled into the through hole the inside.It is more solid and reliable that plastic casing-pipe is connected with metal sleeve.
Protrude screw thread on the above-mentioned described plastic casing-pipe outer surface and can be wall scroll or two.
Four, description of drawings
Fig. 1 is the structural representation of existing lead wire sheath;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a cut-away view of the present utility model;
Fig. 4 is the connection diagram of the utility model and motor.
Five, embodiment
To shown in Figure 4, the utility model comprises metal sleeve 1 as Fig. 2, and the tail end of metal sleeve 1 forms base plate 2, and described metal sleeve 1 outside is set with plastic casing-pipe 3, and plastic casing-pipe 3 outer surfaces are provided with screw thread 7.
Above-mentioned described plastic casing-pipe 3 is directly injection-moulded on the metal sleeve 1, has formed extension injection molded layers 4 at metal sleeve 1 inner surface.The surface of described metal sleeve 1 is provided with through hole 5, extends injection molded layers 4 and is filled into through hole 5 the insides.The bottom surface of described base plate 2 is provided with two salient points 6, the base plate 2 of the tail end of metal sleeve 1 is welded on the surface of motor housing 9, the line outlet 10 of motor communicates with metal sleeve 1, the lead-in wire 11 of motor passes metal sleeve 1, one end connects the motor internal coil windings, and the other end stretches out motor and connects power supply outward.When base plate 2 was welded on motor housing 9 surperficial, two salient points 6 had big electric current to pass through, and very fast fusing makes base plate 2 be adjacent on the surface of motor housing 9 and links together.
Above-mentioned described motor housing 9 can be provided with boss 13 at wire hole 10 position outer surfaces, and described boss 13 can be nested in the protruding rank 8 of metal sleeve 1, and is easier for installation.Be with flexible pipe 14 outside the described motor down-lead 11, the internal thread of flexible pipe 14 1 ends is connected with the screw thread 7 of the outside of plastic casing-pipe 3, makes things convenient for the installation of flexible pipe 14.Described screw thread 7 can be single thread or two screw thread.
