State the side-wall outer side that pull rod 614 protrudes from positioning component A61 always.
Specifically used process:
Arranging plate presss from both sides 2: four plates and presss from both sides 2 points of left and right sides for being respectively placed in circuit board 1 for two groups, and every group is respectively positioned on circuit
On the front and rear sides side of plate 1, the edge of circuit board 1 is put between top plate 21 and bottom plate 22；
Setting cross bar 5: upper a cross bar 5 will be respectively provided between the plate folder 2 of two, left side, between the plate folder 2 of two, right side.Specifically
Will to be nested with a fixing card 4 in each upright bar 3, the quantity positioned as needed selectes fixing buckle A6's and fixing buckle B7
Quantity (the two quantity is identical), and respectively penetrate on cross bar 5 and (guarantee that positioning plate 612 and dentalation 51 match), by left and right
The dentalation 51 of the cross bar 5 of two sides is placed into the side being located remotely from each other, and the rear and front end end of cross bar 5 is each passed through admittedly
Surely it in the hole B42 of card 4, is matched by stopper rod 43 through the roof of fixing card 4 and with non-through hole 410 and realizes that cross bar 5 is opposite
The positioning of fixing card 4.It is provided with through-hole on the side wall of fixing card 4, for the insertion of stopper rod 43, if the outside of circuit board 1 is also
There is cross bar 5 prominent, can be cut with pliers；
Connecting line support rod 8 is set: appropriate number of connecting line support rod 8 being selected according to the length of circuit board 1, if only
The length of a connecting line support rod 8 is needed, several parallel arranged side by side, then only needs protrusion 81 sliding into groove A621
In, the number of positions for being fixedly connected with line as needed selects a certain number of sliding blocks 9, it is slid into sliding slot 83 by bending part 91,
Then protrusion block B72 is slid into groove B82；Range if necessary to the connecting line of support is larger, then multiple groups can will be arranged
Parallel connecting line support bar group, the successively phase of 8 head and the tail of connecting line support rod of every group of connecting line support bar group quantity all the same
A body of rod is even formed, is then plugged in together with fixing buckle A6, fixing buckle B7.The Outside Dimensions of protrusion 81 are without departing from even
The size of 8 body of rod centre of wiring support rod, guarantee when several connecting line support rods 8 be mutually spliced into a root long it is rod-shaped when,
Sliding block 9 can be slided freely between each section across junction；
Adjust the front-rear position of connecting line support rod 8: if front and back is arranged side by side between left and right sides cross bar 5 there are multiple companies
Wiring support rod 8, then by pulling pull rod 614 by positioning plate 612, from the pull-out of the between cog of dentalation 51, (fixing buckle B7 is also this
Sample operation) so that the front and back on cross bar 5 fixing buckle A6 and fixing buckle B7 is moved, the position of regular connecting line as needed, if
The spatial position of connecting line support rod 8 is set, discharges pull rod 614, position of the positioning plate 612 on cross bar 5 is fixed；
It adjusts the level height of connecting line support rod 8: fixing card 4 being moved up and down in upright bar 3, and according to connecting line institute
Fixed position positioning is needed, realization positioning is matched by stopper rod 43 through the side wall of fixing card 4 and with non-through hole 410.It is fixed
It is provided with through-hole on the side wall of card 4, for the insertion of stopper rod 43, if there are also upright bars 3 to protrude at the top of fixing card 4, pincers can be used
Son is cut.
Adjusting slider 9 is in the position on connecting line support rod 8: adjusting position of the fixing card 4 in upright bar 3, controls hook
94 position relative to required regular connecting line pulls up screw rod 93 and moves out hex nut 96 out of hexagonal groove D97
And towards 93 rotary-top of screw rod, the pulling to screw rod 93 is then discharged, if hook 94 is from the bottom of connecting line support rod 8
Connecting line is put into hook 94, and lift screw rod 93 upwards, makes then at sliding slider 9 to the regular connecting line of needs by abjection
Section 942 must be erected to enter in groove C84 as far as possible, and be rotated down hex nut 96 to the top of support plate 92, adjust hexagonal spiral shell
Mother 96 matches with hexagonal groove D97 structure, discharges screw rod 93, and hex nut 96 is fallen into hexagonal groove D97, realizes to connection
The fixation of line.
Connecting line is by good appropriate fixation, so that test circuit is regular clear in entire jig, avoid causes in a jumble
Unnecessary signal interference avoid accidentally processing operation, and hex nut while but also the repair procedures visual field is more clear
96, the cooperation of hexagonal groove D97, compressed spring 95, screw rod 93, hook 94 and groove C84, so that the fixed effect of connecting line
It is very good, and detachably re-assembly, have the function of to be used for multiple times, simplifies operation, save the cost.
The above is the embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize the present invention
