Embodiment
To use the problem dangerous, operational sequence is complicated in order solving, to have proposed the fail safe that a kind of circuit fastener improves circuit, make easy and simple to handle.
Below in conjunction with accompanying drawing, technical characterictic and the advantage with other above-mentioned to the utility model are described in more detail.
Refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the schematic perspective view of circuit fastener of the present utility model, Fig. 2 is the schematic perspective view of the outlet lid of circuit fastener of the present utility model, and a kind of circuit fastener 100 of the present utility model comprises outlet lid 110, outlet passage 120 and securing member 130.
Wire hole 112 is set on outlet lid 110.
On outlet passage 120, have through hole, in the present embodiment, through hole is placed in outlet passage 120 center.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 to the direction of outlet lid 110, and the position of circuit is fixed.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, thereby safe, is operated and can be completed fixingly by screw-in, uses very simple.
As a kind of embodiment, the dead in line of the through hole of outlet passage 120 and wire hole 112, what can ensure like this circuit moves towards smooth and easy, the 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 utility model, 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 that the master of the outlet lid of circuit fastener of the present utility model looks schematic diagram, and outlet lid 110 is a groove, in the bottom of outlet lid 110, along at least three base stations of inwall setting 114 of outlet lid 110.
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 at least three base station 114 centers have location hole, by location hole, the control board of motor are fixed.
As a kind of embodiment, in the bottom of outlet lid 110, along the inwall of outlet lid 110, at least two screw columns 116 are also set.At screw column 116 center, installing hole is set, 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, makes like this intensity of outlet lid 110 higher, and 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, while using casting glue to seal wire hole 112, because screw column 116 is higher, casting glue can be by not 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 utility model and the schematic perspective view of securing member confined state, and outside one end that is placed in outlet lid 110 of outlet passage 120 arranges fastening external screw thread 124.
On the end face of the end of fastening external screw thread 124, along circumference, multiple sections 126 are set.Section 126 quantity is in the case of the width of section 126 allows, The more the better, is conducive to improve the stressed uniformity of circuit 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 sections 126, because the conical surface 136 shrinks gradually away from one end of fastening internal thread 134, all sections 126 are simultaneously toward interior contraction, until the circuit in outlet passage 120 is fixed.This fixed form is reliable, prevents that circuit is pulled off.
Refer to shown in Fig. 6, it is the schematic perspective view of the securing member of circuit fastener of the present utility model, securing member 130 is annular, and fastening internal thread 134 is set in one end of annular inner wall, and 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 like this person easy to use and screws in securing member 130, makes operating process lighter.
The interior area of section of one end that the conical surface 136 is adjacent with fastening internal thread 134 is larger than the interior area of section of the other end away from fastening internal thread 134.
As a kind of embodiment, the conical surface 136 is less than the interior area of section of fastening external screw thread 124 away from the interior area of section of one end of fastening internal thread 134.The small cross sections of the conical surface 136 just can act on section 126, makes to cut into slices 126 toward interior contraction.
As a kind of embodiment, multiple sections 126 distribute along even circumferential on the end face of the end of fastening external screw thread 124.21 sections 126 are set in the present embodiment to be uniformly distributed.
As a kind of embodiment, as shown in Figure 5, in the annulus that multiple sections 126 surround, place buffering ring 127.The diameter of the periphery of buffering ring 127 equals the internal diameter of the closed-loop that multiple sections 126 surround.
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 126 the contraction extruding of avoiding cutting into slices destroys circuit; Buffering ring 127 can also play the fixing more firmly effect of circuit that makes.After the squeezing action of section 126 produces, in the whole segment length of buffering ring 127, buffering ring 127 all tightly touches circuit, can play the effect of sealing, effectively prevents that 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 sections 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, and it is excessive that the external screw thread 122 that prevents outlet passage 120 screws in the degree of depth of wire hole 112 of outlet lid 110, 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 are greater than the length of securing member 130 away from the distance between the end of dividing plate 128.Design can ensure that the conical surface 136 of securing member 130 can touch section 126 like this, thereby along with the screw-in of securing member 130 produces active force with fixed line.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
