Fiber optic cable twist test equipment

Abstract

The invention relates to fiber optical cable twist test equipment. A transmission device of the fiber optical cable twist test equipment comprises a crank-slider mechanism; a slider of the crank-slider mechanism is a stick-shaped slider, and one side of the stick-shaped slider is provided with a drive gear; the toothed slider is engaged with a gear which is rotationally assembled on a machine frame to form a gear rack transmission device; and a twist arm of the fiber optical cable twist test equipment is fixed on a rotating shaft of the gear, and a rotating centre line of the twist arm and a centre line of the rotating shaft of the gear are collinear. A motor drives a crank of the crank-slider mechanism to rotate, the crank drives a connecting rod to perform planar motion, and the connecting rod drives the slider to perform reciprocating linear motion; the slider drives the gear to rotate reciprocally by the drive gear on the slider, and with the reciprocating rotation of the gear, the twist arm which is fixed at one end of the rotating shaft of the gear outputs rotation and twists and drives a fiber optical cable clamed on the twist arm to twist. The fiber optical cable twist test equipment has the advantages that: the structure is simple; the movement is reliable; and the twist arm of the motor can be twisted without rotating forward and backward.

Description

technical field [0001] The invention relates to an optical cable torsion test device. Background technique [0002] With the launch of 3G (3rd generation mobile communications) and FTTH (fiber-to-the-home), with the vigorous development of access networks and customer premises networks, and with the continuous decline in the price of optical receiving devices, the market for indoor optical cables has steadily expanded year by year. Indoor optical cables are thin and soft, easy to install, weak in mechanical strength, and narrow in temperature range. Compared with outdoor optical cables, the requirements for mechanical properties such as tensile strength, lateral pressure resistance, and impact resistance are lower. However, the indoor space is small, there are many turns, and the probability of torsion is high, so the requirements for the repeated torsion performance of indoor optical cables are higher. In order to make indoor optical cables suitable for normal laying in v...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of optical cable torsion test equipment, to solve the problem that the optical cable torsion test equipment in the prior art controls the forward rotation and reverse rotation of the motor through the control part, so as to realize the twist test of the optical cable. Rotation will cause the motor to burn out due to too much heat
