Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] A method for detecting the tensile force of a pressed cable head. Firstly, a photoelectric detector is used to detect whether there is a relative displacement between the cable and the wire nose during the pulling process of the pressed cable head, and to judge whether there is a hollow phenomenon in the cable head; The pulling force is decomposed, and the cable head is judged whether it is qualified by detecting the component force value of the cable being pulled.

[0028] Such as figure 1 , 2 As shown, a pressed cable head carrying tension detection device includes a pressed cable head composed of a wire lug 8 and a cable 7, the wire lug 8 is installed at one end of the cable 7, and the wire lug 8 is fixed and compressed by pressing the tiger mouth 2, The end of the cable 7 is connected to the heig...

Abstract

The invention discloses a method for detecting a born pulling force of a pressed cable head. The method comprises the steps of detecting whether relative displacement between a cable and a wire nose exits in a pulled process of the cable head by means of a photoelectric detector, determining whether a hollow phenomenon of the cable head exits, then decomposing a pulling force which is applied to the cable head by means of a force decomposition device, and determining whether the cable head is qualified through detecting the value of a component force for pulling the cable. A device for detecting the born pulling force of the pressed cable head comprises a pressing jaw, a traction motor and a force decomposition device. According to the method of the invention, in performing end splicing onthe cable and the cable head, whether engagement between the cable and the wire nose is firm and a traction pulling force which can be born by the cable head is measured. Through detection a low changing component force for replacing direct detection of the cable traction force, detecting equipment size and requirement for a force sensor are reduced. Through adjusting the angle, one sensor can beused for realizing testing for the born pulling force of the cable head in a relatively large range. Furthermore the invention provides a method for detecting whether relative displacement between the cable and the wire nose, wherein the hollow condition of the wire nose can be detected.

Description

technical field [0001] The invention relates to the field of power supply equipment, in particular to a method and device for detecting the load-bearing tension of a pressed cable head. Background technique [0002] In the pressing process of the cable head, in order to obtain a firm and reliable cable connection effect, the cable end is usually put into the wire lug and pressed tightly so that the wire lug and the cable are firmly engaged. However, traditional cable clamping devices often do not have the function of testing whether the bite degree of the cable wire and the wire lug meets the load-bearing tension specification. [0003] Existing measurement of the compression degree of the wire lug is mostly adopted: (1) the mode of pulling by manpower after the cable is connected to the wire lug. If the cable does not fall off, it means that the cable is connected firmly. This method is highly subjective, cannot give an accurate bearing tension value, and is time-consumin...
