Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0019] Existing tension testing devices are used to test the theoretical maximum tensile force after the wire harness is broken in a physical state. Without any production and practical application, it is impossible to accurately test the real maximum tensile force value of the wire harness in the actual working environment, which is not in line with reality. Measurements required.

[0020] In view of this, the present invention provides a wire harness pull test system with simple structure, stable operation and high measurement accuracy. The specific structure of the wire harness pull test system is as follows figure 1 As shown, specifically include:

[0021] A first control circuit, a second control circuit, a power supply, a connection indicator light, a tension gauge, a motor, and a harness...

Abstract

The invention relates to the technical field of harness detection, particularly to a harness tension testing system. The harness tension testing system comprises a first control circuit, a second control circuit, a power supply, a wire connection indicator light, a tension meter, a motor and a harness to be tested, wherein the first control circuit is connected with the tension meter, the motor, awire connection bank, the wire connection indicator light and the power supply; a buzzer is connected between the first control circuit and the wire connection bank and with the second control circuit; the second control circuit is connected with the harness to be tested sequentially through a switch circuit and a current source; the current source is connected with an overcurrent protecting circuit. The harness tension testing system is simple in structure, stable in operation and high in measuring precision, and can measure the maximum tension that a harness can bear in practical productionenvironments to achieve accurate harness type selection, thereby improving the safety performance index of products.

Description

technical field [0001] The invention relates to the technical field of wire harness detection, in particular to a wire harness tension testing system. Background technique [0002] The wiring harness is mainly used for controlling installation, connecting equipment, transmitting power, etc., and is a common and indispensable thing in daily life. Since the wire harness is electrified, special care is required for installation. The wire harness is made through three processes of drawing, twisting, and coating. The more complex the model specification, the higher the repeatability. Drawing is a technical processing method in which the metal is forced to pass through the mold under the action of an external force, the cross-sectional area of ​​the metal is compressed, and the required cross-sectional area shape and size are obtained. Stranding is to improve the wire harness. The softness and integrity of the wires allow more than two single wires to be intertwined together in t...
