Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Referring to Fig. 1, Fig. 2 and Fig. 3, easy conducting wire draws electric machine structure on a kind of RO pumps, includes mounted on diaphragm pump Motor（It is not shown in figure）On end cap 1.The side of end cap 1 offers the threading groove 11 of perforation 1 inside and outside both ends of the surface of end cap, wears Wire casing 11 is approximate rectangular straight slot, is connected between adjacent side by fillet.End cap 1 is located at threading groove 11 towards end cap 1 Outer end face opening is circumferentially provided with position-limited rack 2.Position-limited rack 2 includes the side plate of be disposed around threading groove 11 weeks three sides thereto 22 and it is connected to the top plate 23 of the top of side plate 22.End cap 1, side plate 22 are enclosed what is connected with threading groove 11 with end cap 1 Locating slot 21.Top plate 23 is located at the limiting slot 231 that the notch position of locating slot 21 is further opened with.

Referring to Fig. 1, Fig. 4 and Fig. 5, in threading groove 11 interference be connected with a volume be more than 11 volume of threading groove wire bushing 3. Wire bushing 3 is made of elastic rubber, and the cell wall extruding that slot 11 is threaded during insertion threading groove 11 shrinks deformation.Shield The spacing block set 31 mutually chimeric with limiting slot 231 is additionally provided on line set 3.Wire bushing 3 is embedded by threading groove 11 in locating slot In 21, and when spacing block set 31 is chimeric with limiting slot 231, end face and the top plate 23 of wire bushing 3 offset.

Referring to Fig. 4 and Fig. 5,1 inclined two wire guide 32 of opposite end cap is further opened on wire bushing 3.Two wire guides 32 are Bellmouth and its axis is parallel to each other.The maximum inner diameter of wire guide 32, which is less than, is threaded through 32 inside conductor of wire guide（It is not shown in figure） Outer diameter.The opening of the larger one end of 32 internal diameter of wire guide is located at wire bushing 3 towards on the end face inside end cap 1, and internal diameter is smaller by one The opening at end is arranged on the notch position of locating slot 21.And wire bushing 3 be located at be provided with opening both ends of the surface be adjacent surface.

Referring to Fig. 1 and Fig. 4, also pressure is equipped with the cushion 4 that limitation wire bushing 3 deviates from threading groove 11 on wire bushing 3.Cushion 4 are equally made of elastic rubber.Cushion 4 is installed in by the fixing bolt 5 being threadedly coupled with end cap 1 on end cap 1.Wire bushing 3 The end face for being located towards cushion 4 is provided with towards the raised elastic projection 33 of cushion 4.When cushion 4 is pressed by fixing bolt 5 When being located on wire bushing 3, increase with the pressure of fixing bolt 5, elastic projection 33 gradually shrinks deformation, while cushion 4 Elastic deformation occurs.Make the end face that cushion 4 is not provided with elastic projection 33 with wire bushing 3 that can also abut.Conducting wire is from elasticity Pad 4 and the bearing surface of wire bushing 3 are pierced by.

Referring to Fig. 1 and Fig. 4, the both sides that end cap 1 is located at wire bushing 3 offer guiding conducting wire installation path in end cap 1 Passing channel 12.Also press the crimping frame equipped with the 12 inside conductor sliding of limitation passing channel in the top that end cap 1 is located at passing channel 12 6.One end of crimping frame 6 is set on the body of fixing bolt 5, and passes through bolt cap and crimping frame 6 is pressed on cushion 4.Crimping The recess portion 61 coordinated with passing channel 12 is further opened on frame 6.It is enclosed between recess portion 61 and passing channel 12 and is worn for conducting wire If cable-through hole.

During installation, conducting wire is penetrated in wire guide 32, since the open end of wire guide 32 is obliquely installed, so it is tilted Part is equivalent to guide surface, can facilitate wearing for conducting wire.It is smaller positioned at internal diameter when two conducting wires are threaded through in wire guide 32 The conducting wire of one end passes through the notch of threading groove 11 from locating slot 21 to be pierced by.Wire bushing 3 is pressed into threading groove 11 later, and presses and sets It is contacted to wire bushing 3 with top plate 23, while spacing block set 31 is caught in limiting slot 231.Compressive deformation occurs for wire bushing 3, makes to lead String holes 32 has the trend shunk, and further compresses conducting wire, improves leakproofness.

This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but As long as it is all protected in the right of the utility model by Patent Law.
