[0013] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only to represent selected embodiments of the utility model.

[0014] Please refer to Figs. 1-2 In the embodiments of the utility model, a jig for quickly determining the pair-twisted pitch of four pairs of network cables comprises a test base plate 1, the test base plate 1 is provided with four card line grooves 2, the test base plate 1 is provided with a test starting line 5 at each card line groove 2, the test base plate 1 is provided with a plurality of single pitch mark lines 4 at each card line groove 2, and the pitch test range line 3 is arranged at the single pitch mark line 4 farthest from the test starting line 5. The device overcomes the shortcomings of the existing test method (ten pitches are easily miscounted during testing, and it is inconvenient to place and measure the twisted cable on the meter ruler), the pitch of each specification of cable is marked on the base plate, and obvious upper and lower limit marks (pitch test range lines) are arranged; by arranging the grooves corresponding to the pair-twisted outer diameter on the base plate, the twisted cable can be clamped in the groove during testing, the twisted cable can be stably measured during measurement, and the testing is more accurate; different test plates are arranged for each type of cable, and different test plates are used according to the cable number of the production line during production.

[0015] Each card line groove 2 is provided with ten single pitch mark lines 4, and the pitch of adjacent single pitch mark lines 4 is the same; the pitch test range lines 3 of the four card line grooves 2 are different in size; the test base plate 1 adopts a PEEK polyether ether ketone base plate; the PEEK polyether ether ketone material is used as the base plate, the thermal expansion and cold shrinkage coefficient is small, and the test accuracy under different temperature environments is further ensured, and the weight is light.

[0016] The general Ethernet cable is four pairs of cable, so the device is provided with four pairs of grooves on the bottom plate, and mark lines for observing each pair of pitches, and determination lines for the upper limit and lower limit of the final determination pitch; by setting the grooves close to the size of the pair of stranded cable to be tested, the pair of stranded cable to be tested can be tightly clamped during testing, facilitating testing; each product is separately made with a test plate, and the corresponding test plate is used during production; convenient to use; 10 are set for each pitch test (if the pitch is small, 20 can also be set), the upper and lower tolerances are enlarged to facilitate observation of the upper and lower limits.

[0017] The working principle of the utility model is: overcome the deficiency of prior art test mode (test when temporary number out ten pitch easy to number error, stranded wire in meter on the placement measurement is inconvenient), the device will each kind of specification cable pitch is engraved on the bottom plate, set obvious upper limit and lower limit mark (pitch test range line), adopt PEEK polyether ether ketone material as the bottom plate, the thermal expansion and cold contraction coefficient is small, further guarantee the test precision under different temperature environment, light in weight, through setting the corresponding stranded outer diameter groove on the bottom plate, the stranded cable is clamped in the groove during testing, the stranded wire can be measured stably during measurement, and the testing is more accurate; each kind of cable is provided with different test plate, and different test plate is used according to the production cable number during production.

[0018] Finally, it should be noted that: the above only for the preferred embodiment of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features.
