Embodiment
Using the problem dangerous, operational sequence is complicated to solve, proposing a kind of circuit fastener to improve the fail safe of circuit, making easy and simple to handle.
Below in conjunction with accompanying drawing, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
Refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the schematic perspective view of circuit fastener of the present invention, Fig. 2 is the schematic perspective view of the outlet lid of circuit fastener of the present invention, and a kind of circuit fastener 100 of the present invention comprises outlet lid 110, outlet passage 120 and securing member 130.
Outlet lid 110 sets out string holes 112.
Outlet passage 120 has through hole, and in the present embodiment, through hole is placed in the center of outlet passage 120.One end of outlet passage 120 is arranged on outlet lid 110.Through hole docks with wire hole 112, so that circuit is successively drawn via wire hole 112, through hole from outlet lid 110.
Circuit passes from wire hole 112, and through outlet passage 120, securing member 130 is sleeved on outlet passage 120, and securing member 130 screws in the direction of outlet lid 110, is fixed the position of circuit.The length of outlet passage 120 is greater than the length of securing member 130, ensures that securing member 130 can be arranged on outlet passage 120 completely.The fastening means of this circuit is reliable, thus fail safe is high, can complete fixing, use very simple by screw-in operation.
As a kind of embodiment, the through hole of outlet passage 120 and the dead in line of wire hole 112, what can ensure circuit like this moves towards smooth and easy, not bending of not tiing a knot.
Shown in Fig. 5, it is the schematic perspective view of the outlet passage of circuit fastener of the present invention, and the inwall of wire hole 112 arranges internal thread, and one end of outlet passage 120 arranges external screw thread 122.The internal thread of wire hole 112 matches with the external screw thread 122 of outlet passage 120, and the mode that is threaded connection like this makes outlet lid 110 and outlet passage 120 strong bonded, and sealing is high.
Shown in Fig. 2 and Fig. 3, Fig. 3 is the schematic front view of the outlet lid of circuit fastener of the present invention, and outlet lid 110 is a groove, and in the bottom of outlet lid 110, the inwall along outlet lid 110 arranges at least three base stations 114.
The height of base station 114 is identical, and the end face of all base stations 114 is in same plane, and base station 114, for the control board of fixed electrical machinery, ensures that the control board of motor is entirely installed.Wherein the center of at least three base stations 114 has location hole, is fixed by the control board of location hole by motor.
As a kind of embodiment, in the bottom of outlet lid 110, the inwall along outlet lid 110 also arranges at least two screw columns 116.Installing hole is set at the center of screw column 116, by installing hole, outlet lid 110 is arranged on motor body.
More preferably, outlet lid 110 uses the material of good heat dispersion performance, makes through manufacturing process, and make the intensity of outlet lid 110 higher like this, the dimensional uniformity of bulk article is high.
As a kind of embodiment, the end face of screw column 116 is higher than the end face of all base stations 114.After circuit fixedly completes, when using casting glue to seal wire hole 112, because screw column 116 is higher, casting glue can not by flowing in installing hole.
As a kind of embodiment, one end of outlet passage 120 is arranged on outlet lid 110, and the other end is placed in the outside of outlet lid 110.
Shown in Fig. 4 and Fig. 5, Fig. 4 is the outlet passage of circuit fastener of the present invention and the schematic perspective view of securing member confined state, and one end being placed in the outside of outlet lid 110 of outlet passage 120 arranges fastening external screw thread 124.
The end face of the end of fastening external screw thread 124 circumferentially arranges multiple section 126.The quantity of section 126 is when the width of section 126 allows, The more the better, is conducive to improving the circuit uniform force among section 126.
When securing member 130 is sleeved on outlet passage 120, fastening internal thread 134 screws in fastening external screw thread 124 gradually, the conical surface 136 of securing member 130 continuingly acts on multiple section 126, because the conical surface 136 one end away from fastening internal thread 134 is shunk gradually, all sections 126 are past interior contraction simultaneously, until be fixed by the circuit in outlet passage 120.This fixed form is reliable, prevents circuit to be pulled off.
Refer to shown in Fig. 6, it is the schematic perspective view of the securing member of circuit fastener of the present invention, and securing member 130 is annular, and arrange fastening internal thread 134 in one end of annular inner wall, fastening internal thread 134 matches with the fastening external screw thread 124 of outlet passage 120.On annular inner wall, the other end also arranges the conical surface 136.
In the present embodiment, the gabarit of securing member 130 is turret head nut, designs person easy to use like this and screws in securing member 130, make operating process lighter.
In one end that the conical surface 136 is adjacent with fastening internal thread 134, area of section is than large away from area of section in the other end of fastening internal thread 134.
As a kind of embodiment, the conical surface 136 is less than area of section in fastening external screw thread 124 away from area of section in one end of fastening internal thread 134.The small cross sections of the conical surface 136 just can act on section 126, makes section 126 toward interior contraction.
As a kind of embodiment, multiple section 126 is circumferentially uniformly distributed on the end face of the end of fastening external screw thread 124.Arrange 21 sections 126 in the present embodiment to be uniformly distributed.
As a kind of embodiment, as shown in Figure 5, buffering ring 127 is placed in the annulus that multiple section 126 surrounds.The diameter of the periphery of buffering ring 127 equals the internal diameter of the closed-loop that multiple section 126 surrounds.
As a kind of embodiment, buffering ring 127 is made up of elastomeric material.Buffering ring 127 can play the circuit that protection is wherein passed, and avoids the contraction extruding of section 126 by broken wire; Buffering ring 127 can also play and make that circuit is fixing more firmly to be acted on.After the squeezing action generation of section 126, in the whole segment length of buffering ring 127, buffering ring 127 all tightly touches circuit, can play the effect of sealing, effectively prevents dust, water from stretching into outlet lid 110 by the through hole on outlet passage 120.
As a kind of embodiment, the length direction of multiple section 126 is along the axis direction of through hole.
As a kind of embodiment, between the external screw thread 122 of outlet passage 120 and the fastening external screw thread 124 of outlet passage 120, dividing plate 128 is set.Dividing plate 128 is fixed on outlet passage 120, plays the effect of screw-in position of restriction securing member 130, prevents the external screw thread 122 of outlet passage 120 from screwing in the degree of depth of the wire hole 112 of outlet lid 110 excessive, affects the installation of securing member 130.
In the present embodiment, dividing plate 128 uses hexagonal flange nut, screws in and is installed on outlet passage 120.
The end face that dividing plate 128 is adjacent with fastening external screw thread 124 and section 126 away from dividing plate 128 end between distance be greater than the length of securing member 130.Such design can ensure that the conical surface 136 of securing member 130 can touch section 126, thus along with the screw-in generation active force of securing member 130 is with fixed line.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
