The distance between pin 11 keeps constant.
Fig. 2 is the front view of measurement base, and Fig. 3 is the side view of measurement base, and Fig. 4 is the top view of measurement base.
In conjunction with Fig. 2 and Fig. 4, described measurement base is lived by the first outer sideboard 20, the second outer sideboard 21, first
In dynamic baffle plate 22, second, sideboard 23, fixed seat 24, footing 25, screw rod 26, movable chain 28, scale 27 form；
Described activity chain 28 is embedded in the groove of described fixed seat 24, and described first outer sideboard 20, second is outer to live
In sideboard 22, second in dynamic baffle plate 21, first, sideboard 23 is all relatively fixed with described activity chain 28, and with activity
Movement in groove for the chain 28 and along measurement symmetrical, the equidistant movement of base centerline；
The bottom of described fixed seat 24 is provided with the footing 25 for supporting described fixed seat 24；
The side of described fixed seat 24 be provided with for measurement the first outer sideboard 20, the second outer sideboard 21, the
The described scale 27 of sideboard 23 distance between any two in sideboard 22, second in.
Wherein, in sideboard 22 and second, the distance between sideboard 23 determines in the middle of described cable in described first
The minimum zone of head deviation length；
Between described first outer sideboard 20 and the second outer sideboard 21, distance determines cable mid head deviation length
Maximum magnitude.
In described first, the distance between sideboard 22 and the first outer sideboard 20 can set；Or live in described second
The distance between dynamic baffle plate 23 and the second outer sideboard 21 can set；
Wherein, described first outer sideboard 20, live in sideboard 22, second in the second outer sideboard 21, first
The distance of dynamic baffle plate 23 can be adjusted by described screw rod 26 and fixing.
Accordingly, the present invention also provides one kind to measure cable mid head deviation using above-mentioned cable mid head deviation measuring apparatus
Method, as shown in figure 5, methods described includes:
Step 100, by the screw rod of the measurement base of described cable mid head deviation measuring apparatus, adjusts the first outer active catch
Plate, the second outer sideboard, sideboard in first, in second sideboard distance, set cable mid head deviation length
Scope；
Step 101, measures the copper shield of cable mid head using the protractor of described cable mid head deviation measuring apparatus
Length between cold shrink tube；The distance between stitch of described two indicators of protractor is the copper shield of cable mid head
Length between cold shrink tube；
Step 102, the stitch of two indicators of described protractor is put into sideboard in the first of described measurement base
And in the space in the space between sideboard in second or between the first outer sideboard and the second outer sideboard；
Step 103, if can put in the space between sideboard in sideboard and second in described first, judges
The offset dimensions that described cable mid head deviation meets minimum require；
Step 104, if can put in the space between the described first outer sideboard and the second outer sideboard, judges
The offset dimensions that described cable mid head deviation meets maximum require；
Step 105, if can not put in the space between the described first outer sideboard and the second outer sideboard, sentences
Described cable mid head deviation of breaking does not meet offset dimensions and requires.
The actual application of the present invention described in detail below:
As shown in fig. 6, being the schematic diagram with medial head annex for the cable mid head of shrinkage annex to be installed, Fig. 7 is centre
The schematic diagram of head annex.As shown in figure 8, medial head annex is enclosed within cable mid head during construction, after determining position, medial head
Annex is fixed with regard to this.
The following two kinds situation occur after fixation:
As shown in figure 9, the inner semiconductor layer of shrinkage annex is just fixed on the centre of cable mid head.
As shown in Figure 10, the inner semiconductor layer of shrinkage annex is not fixed to the centre of medial head.
When mistake installation as shown in Figure 10 occurs:
First: in shrinkage annex, semiconductor has side is crosslinked with cable major insulation, causes cable major insulation and shrinkage attached
Part semiconductor layer has a gap.
Second: have significant difference when the length vs of in figure l1 correctly install, and this difference is visual in installation process.
Semi-conductive layer in cold shrink tube should be wrapped in major insulation at least length of 0.5cm, and guarantee does not affect cable
Normal operation.Therefore, semi-conductive layer allows the maximum length deviateing to should be l2 and deducts 0.5cm, i.e. l3 (the black marking part of Figure 11
Point).
So, the length of the distance between cold shrink tube to copper shield l should be between l1+l3 and l1-l3, guarantee chi
Very little is within zone of reasonableness it is ensured that the operation safety of cable.
Under normal circumstances, copper shield to the distance between cold shrink tube length should be:
L1=5cm-1/2 [shrinkage length of tube-(crimping length of tube+2* major insulation length)]
When size there occurs skew:
Permissibl e skew range is:
L=l1 ± l3
=l1 ± (l2-0.5)
=l1 ± [1/2 (semi-conductive layer length-crimping length of tube) -0.5]
In this permissibl e skew range, semiconductor electric layer length and crimping length of tube are all known, therefore, according to formula l=
L1 ± [1/2 (semi-conductive layer length-crimping length of tube) -0.5], you can be derived by the scope of l, this scope may act as
In sideboard 22, second on setting measurement base first, sideboard 23, the first outer sideboard 20, second are outer movable
The foundation of baffle plate 21.Specifically, in sideboard 22, second, the distance between sideboard 23 is set to l=l1-l3 in first
=l1- [1/2 (semi-conductive layer length-crimping length of tube) -0.5]；First outer sideboard 20, the second outer sideboard 21 it
Between distance be set to l=l1+l3=l1+ [1/2 (semi-conductive layer length-crimping length of tube) -0.5]
Therefore, the protractor being provided by the present invention measures cold shrink tube to the distance between copper shield length l, then by angulation
Device is put on measurement base, sees whether can put in sideboard 22, second in first between sideboard 23, if can, full
The minimum offset dimensions of foot；If can put between the first outer sideboard 20, the second outer sideboard 21, meet the inclined of maximum
Difference size；If can not put into completely between the first outer sideboard 20, the second outer sideboard 21, exceed legitimate skew model
Enclose, judge that shrinkage annex fails to be properly attached in cable mid head, need to revise.
Implement the cable mid head deviation measuring apparatus of the present invention, can in the cable between its internal size of head external detection
Whether there is deviation, cable dimension deviation is prevented with this, thus reducing the frequency of the dimensional discrepancy causing trouble because of cable mid head,
Reduce customer outage hours, evade set cold shrink sleeve during the above content of blind spot be with reference to specific preferred embodiment pair
The present invention made further describe it is impossible to assert the present invention be embodied as be confined to these explanations.For this
For bright person of an ordinary skill in the technical field, without departing from the inventive concept of the premise, some letters can also be made
Single deduction or replace, all should be considered as belonging to protection scope of the present invention.
