Description
Technical field
The utility model relates to a kind of cable fastener, is used for the outgoing cable line secure fixation with transducer or other electronic equipments.
Technical background
Cable outlet protection design is broadly divided into three classes in the high speed optoelectronic product sensor structural design in the market.The first kind is that the fixing head of employing standard outsourcing piece cable is realized cable protective, and the required cost of this type of structural design is low, and is fastening effective, but product structure design is limited by the standard component size, is difficult to find the standard outsourcing piece that satisfies the product design demand fully.Second class is for adopting the outside support form at the line outlet attached cable, and the fastening effect of this structural design is better, but appearance poor, cost is higher, and generally installs additional under the situation of bellows at skin at cable on the railway high speed locomotive, and this structure can't be used.The 3rd class is for adopting the method for inner perfusion silica gel, bonding force by filling gel is realized the fastening of cable, this method is simple, it is good to be used for ground installation (product) cable fixed effect, but when being used for railway locomotive mobile unit (product) or under the stressed bigger situation of product cable, fastening effect is bad, there is certain limitation in this method manufacturability simultaneously, the dried glue of silica gel needs the long time, influences product complete machine productivity ratio.
The utility model content
The purpose of this utility model is to propose a kind of cable fastener, can guarantee effective protection of cable lead-out wire, promotes the global reliability of product.
Technical solution of the present utility model is as follows:
A kind of cable fastener, this cable fastener is arranged on the product body, and the cable of drawing from this product body passes from this cable fastener; This cable fastener comprises bellows adapter, cable solidus circle and pipe joint; One end of bellows adapter is connected with bellows, and an end of the other end of bellows adapter and pipe joint is by being threaded; The other end of pipe joint is installed on the described product body; Pass in the through hole that cable is provided with from pipe joint and bellows adapter vertically; Cable solidus snare is contained on the cable, and is arranged on pipe joint and is connected with the bellows adapter in the cavity that the back forms.
Be provided with copper washer between bellows adapter and pipe joint, described copper washer is sleeved on the cable.
The end that cable solidus circle contacts with pipe joint is taper; The contact-making surface of cable solidus circle and pipe joint is the conical surface.
Beneficial effect:
1) this structural design is a kind of universal structural design, for the cable in collinear footpath all can be by not adjusting the outlet protection that the Element Design size realizes cable.This device can be used as high speed optoelectronic sensor cable fastening structure, also can be as the cable outlet protection of other electronic product or electromechanical integrated product.
2) this structural design cost is lower, presses 1000 calculating of product lot quantity, realizes that the copper washer 3 of design effect and cable solidus circle 4 add up to the about 2-3 of cost unit one cover.
3) can to realize that the cable line outlet protects required fastening force adjustable, controlled for this structural design.At first can adjust cable solidus circle 4 deformation sizes, adjust fastening force by the thickness of adjusting copper washer 3.Secondly when bellows adapter 1 and pipe joint 5 thread connection, if configuration torque spanner, can guarantee that final fastening force is a definite value, guarantee that this fastening force can be not too small and cause the stressed play that takes place when big of cable to guarantee that simultaneously this fastening force can be not excessive and cause the stressed damage of cable.
4) this structural design assembling is simple, is easy to processing and assembling, is convenient to promotion and implementation.

Label declaration: 1, bellows adapter 2, cable 3, copper washer 4, cable solidus circle 5, pipe joint.
Embodiment
Below with reference to figure and specific implementation process the utility model is described in further details:
As Fig. 1～4, the cable fastener is realized effective protection of cable outlet by following structure: cable 2 passes bellows adapter 1, and bellows adapter 1 one ends connect bellows, and the other end is the external screw thread interface; Copper washer 3 and cable solidus circle 4 are passed cable successively, and copper washer 3 materials are red copper, and the concrete trade mark is T3, and cable solidus circle material is an acrylonitrile-butadiene rubber; Pipe joint 5 is passed cable, and pipe joint 5 is used for being connected cable overall structure and product body pedestal; Pipe joint 5 one ends are provided with internal thread, pipe joint 5 other ends product body of practicing midwifery, pipe joint 5 and bellows adapter 1 internal and external threads are tightened mutually, under the effect of screw thread power, bellows adapter 1 passes to cable solidus circle 4 by copper washer 3 with screw thread power, along with screw thread is tightened, causes that deformation takes place cable solidus circle 4, the reaction force that this deformation produces compresses cable, realizes effective protection of cable outlet mouth.Need to prove that because cable solidus circle 4 adopts the rubber material, therefore, when equipment, the 4 compacted generation deformation of cable solidus circle cause the shape of the cable solidus circle 4 among Fig. 1 and the shape among Fig. 3 b inconsistent.
Embodiment 1: cable 2 external diameter Φ 14 ± 0.3mm; The hickey of bellows adapter 1 is metric system external screw thread M25 * 1.5mm, and reach is 7 ± 0.1mm; The material of copper washer 3 is red copper (trade mark T3), and thickness is 2 ± 0.1mm, internal diameter Φ 14.5 ± 0.1mm, external diameter Φ 22mm; The material of cable solidus circle is an acrylonitrile-butadiene rubber, and contour structures is taper, 60 ° of taperings, and endoporus is of a size of Φ 14.5 ± 0.1mm, highly is 7mm; There is a taper hole inside of pipe joint 5, and 60 ° of taperings, the hickey of pipe joint 5 are metric system internal thread M25 * 1.5mm, and reach adds depth of recess 9+0.2+0.4mm.
The structure assemble sequence is as follows, earlier cable 2 is passed bellows adapter 1, according to Fig. 1 copper washer 3 and cable solidus circle 4 and pipe joint 5 are passed cable 2 successively then, tighten bellows adapter 1 and pipe joint 5 then, tighten and to finish integrally-built assembling.
This specific embodiment cable solidus circle 4 can be realized the compressive deformation of 2.1mm-2.5mm, can provide about 30kg-50kg fastening force by practical proof, with the cable after the assembling dismantle visual judgement can confirm cable in fastening process for to damage, realization expectation design effect.
