Description

TECHNICAL FIELD

[0001] The utility model relates to cable conductor measurement technical field, concretely is a big square conductor pitch measuring scale. BACKGROUND

[0002] The conductor of cable is twisted by many line cores, and the conductor pitch refers to the distance of the twisted body (or wrapping tape, line) advancing along the twisted axis in one rotation. In the manufacturing process of electric wire and cable, the measurement of conductor pitch is a key link, which affects the winding quality and electrical performance of electric wire and cable.

[0003] The common conductor pitch measurement methods include direct pitch measurement, paper tape pitch measurement, shift line pitch measurement and average pitch measurement.

[0004] When using the common measurement methods to measure the pitch, it is found that the direct pitch measurement, paper tape pitch measurement and average pitch measurement cannot clearly distinguish the parallel wires or large pitch strands on the conductor. When the number of parallel wires is large, the method of counting the number of single wires is not practical.

[0005] The shift line pitch measurement is suitable for the outer layer with more roots or soft line core, such as large cross-sectional area conductor line core and multi-core telephone cable. In the specific operation, one single wire is removed from the measured twisted layer, and the removed length is not less than the length of one pitch. Then, the distance between the adjacent two gaps left after removing the single wire is directly measured by using a steel ruler or a vernier caliper. However, this method will damage the conductor, resulting in waste of the conductor and only allowing measurement of the front and rear ends (because it will damage the conductor, such as measurement in the middle section, which will cause cable defects).

[0028] Please refer to Figure 1 and Figure 2 In the embodiment, the bottom of the semicircle clasp one 202 is integrally formed with a closing plate one 2021, and the bottom of the semicircle clasp two 203 is integrally formed with a closing plate two 2031; the locking piece comprises a quick release screw 11 and a nut 12, one end of the quick release screw 11 is fixed with a handle provided with anti-slip protrusions on the surface, the other end is sequentially penetrated through the closing plate two 2031 and the closing plate one 2021 and is threadedly connected with the nut 12, and rubber sheets one 204 are fixed on the inner walls of the semicircle clasp one 202 and the semicircle clasp two 203.

[0029] Specifically, the semicircle clasp one 202 and the semicircle clasp two 203 can well clamp and fix the circular conductor main body 1, and improve the stability after clamping, the quick release screw 11 can be directly twisted by the staff, which is convenient and fast, and does not need to rely on tools, so as to cooperate with the nut 12 to lock the closing plate one 2021 and the closing plate two 2031, so as to ensure that the semicircle clasp one 202 and the semicircle clasp two 203 clamp the conductor main body 1, and the rubber sheets one 204 are fixed on the inner walls of the semicircle clasp one 202 and the semicircle clasp two 203, which can avoid causing bruising to the conductor main body 1 on one hand, and can increase the damping property on the other hand, thereby improving the stability after clamping.

[0035] Specifically, when the height of the measuring rod 1002 needs to be adjusted, the staff can loosen the extrusion force on the measuring rod 1002 by screwing the tightening screw 16, so that the measuring rod 1002 can slide in the adjusting cavity 13 through the limiting sliding block 14 to the appropriate position, and then the tightening screw 16 is tightened to push the pressing block 17 to move on the hollow rod 1001 through the thread rotation of the tightening screw 16, so that the pressing block 17 drives the rubber sheet two 18 to move close to the measuring rod 1002, and finally extrudes the measuring rod 1002 to give the measuring rod 1002 an extrusion force to ensure the stability of the measuring rod 1002 in the adjusting cavity 13, and the rubber sheet two 18 serves to improve the damping property and further improve the stability of the measuring rod 1002.

[0036] In use:

[0037] The entire measuring structure is clamped and fixed on the conductor body 1 by the clamping assembly 2. When clamping, the semi-circular clamping ring one 202 or the semi-circular clamping ring two 203 is pried to the two sides away from each other, so that the distance between the semi-circular clamping ring one 202 and the semi-circular clamping ring two 203 is increased, then the conductor body 1 is inserted between the semi-circular clamping ring one 202 and the semi-circular clamping ring two 203, and the tightening screw 16 is inserted between the semi-circular clamping ring one 202 and the semi-circular clamping ring two 203, and then the nut 12 is screwed in to tighten the semi-circular clamping ring one 202 and the semi-circular clamping ring two 203 to close them, and the entire clamping assembly 2 is clamped and fixed on the conductor body 1.
