Embodiment:
Below in conjunction with accompanying drawing 1 to 3 and embodiment, the present invention is described in further detail.
The general switching device of a kind of cable needle-type plug, as shown in Figure 1, comprise conductive rubber contact plate 3, hard contact dish 4, nonmetal removable platen 6, hold-down bolt 7, conversion equipment body 5 and outgoing cable 8, conductive rubber contact plate 3, hard contact dish 4 and nonmetal removable platen 6 are installed in conversion equipment body 5.
When conductive rubber contact plate 3 and shape, size and the spacing of the tip side 9 of tested cable 1 needle-type plug adjacent surface meet the general switching device of cable needle-type plug with tested cable 1 needle-type plug docking, each contact pin 10 of tested cable 1 needle-type plug at least reliably contacts with a contact and each contact can not contact with two contact pins 10 of tested cable 1 needle-type plug the while, as shown in Figures 2 and 3.3 circles and the part contact end that in Fig. 3, are positioned on tip side intersect, and represent three situations that contact pin 10 contacts with tip side of tested cable 1 needle-type plug.The shape of conductive rubber contact plate 3 and the tip side 9 of tested cable 1 needle-type plug adjacent surface can be semisphere, cuboid, the square bodily form, truncated cone-shaped or cylindrical etc.Sectional dimension and the spacing between adjacent contacts end 9 that tip side 9 coordinates with the contact pin of tested cable 1 needle-type plug are less, the general switching device of cable needle-type plug contacts more reliable while docking with tested cable 1 needle-type plug, versatility is better, preferably the distance between adjacent contacts end 9 is not more than the pin diameter of needle-type plug and the distance between adjacent contact pin, tip side 9 is not more than contact pin sectional dimension with the sectional dimension of the contact pin contact position of needle-type plug, tip side 9 is evenly distributed on conductive rubber contact plate 3 with identical spacing, tip side 9 adopts semisphere, half bulb diameter is 0.5 millimeter.Conductive rubber contact plate 3 external diameters are 50 millimeters, 100 millimeters, 150 millimeters equidimension series, according to the pin diameter of tested cable 1 needle-type plug, select.
Hard contact dish 4 is corresponding one by one with the tip side of conductive rubber contact plate 3 adjacent surfaces, can make by pressing or bonding etc. mode the tip side corresponding contact one by one of hard contact dish 4 and conductive rubber contact plate 3 adjacent surfaces, also can be with bolts, other method such as riveted joint, as long as can make the two tip side realize reliable contact.
The tip side of face and the heart yearn of outgoing cable 8 one end that conductive rubber contact plate 3 deviates from hard contact dish 4 pass through the corresponding connection of welding, outgoing cable 8 other ends are drawn by the opening of nonmetal removable platen 6, conversion equipment body 5, for being connected with detecting instrument equipment.Hold-down bolt 7 is assemblied on conversion equipment body 5, while screwing hold-down bolt 7, can drive successively nonmetal removable platen 6, hard contact dish 4 and conductive rubber contact plate 3 to move, conductive rubber contact plate 3 is contacted with the contact pin 10 of tested cable 1 needle-type plug with the tip side 9 of tested cable 1 needle-type plug adjacent surface, realize docking of the general switching device of cable needle-type plug and tested cable 1 needle-type plug.
While using the general switching device of cable needle-type plug, first by this general switching device with by chaining pin type cable splice, be connected, screw hold-down bolt 7, hold-down bolt 7 drives nonmetal removable platen 6, hard contact dish 4 and conductive rubber contact plate 3 to move, and conductive rubber contact plate 3 is contacted with the contact pin 10 of tested cable 1 needle-type plug with the tip side 9 of tested cable 1 needle-type plug adjacent surface.Because the contact pin 10 of tested cable 1 needle-type plug may contact 2 above tip sides 9 simultaneously, need to before test, to contact, divide into groups.Group technology is: by the general switching device of cable needle-type plug and tested cable 1 needle-type plug to after connecting, measure the resistance value between one end heart yearn outside the general switching device outgoing cable 8 leading-out conversion device bodies 5 of cable needle-type plug, according to the on off operating mode between institute's measuring resistance value judgement heart yearn, to judge that the heart yearn in conducting state is divided into one group, a heart yearn of the corresponding tested cable 1 of each core assembly line of the general switching device outgoing cable 8 of cable needle-type plug obtaining accordingly.Above-mentioned resistance measurement and grouping process can adopt common resistance apparatus by manually completing, also the exit of the general switching device outgoing cable 8 of cable needle-type plug can be connected with special test equipment equipment, by special test equipment equipment, carry out core line resistance and automatically measure, and carry out automatic decision grouping by related software.
