Detailed Description

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, an embodiment of an overhead cable current tester provided in an embodiment of the present invention includes:

a clip-on ammeter 1; the bottom of the clamp-on ammeter 1 is provided with an insulating rod 2, the clamp-on ammeter 1 is connected with a signal transmission line 3, and the signal transmission line 3 is connected with a host 4 capable of checking current data detected by the clamp-on ammeter 1.

In this embodiment, operating personnel is close to detection circuitry 5 with pincerlike ampere meter 1 through insulating rod 2, then presss from both sides tight circuit 5 with pincerlike ampere meter 1, observes current data through host computer 4, and through foretell design, the staff can not need the high altitude construction, only need stand subaerial operation can, greatly reduced's operational risk to it is more convenient to test, shortens test time, promotes work efficiency.

Further, the insulating rod 2 is detachably connected with the clip-on ammeter 1.

It should be noted that, the insulating rod 2 and the clip-on ammeter 1 are detachably connected, so that a worker can conveniently store the current tester when not using the current tester.

Further, a threaded connector is arranged at the bottom of the clamp-on ammeter 1;

the top of the insulating rod 2 is provided with a threaded insertion part which is inserted into the threaded connection port and is in threaded connection with the threaded connection port.

When the worker needs to perform work, the worker can complete the attachment between the insulating rod 2 and the current meter clamp 1 by inserting the threaded insertion portion into the threaded connection and rotating the insulating rod 2 clockwise with respect to the current meter clamp 1.

Furthermore, the clamp-on ammeter 1 is provided with a clamping part in a lost manner;

the top of the insulating rod 2 is provided with a buckle, and the buckle and the clamping part are mutually clamped.

It should be noted that, when the worker needs to work, the installation between the insulating rod 2 and the clamp ammeter 1 can be completed only by mutually engaging the engaging portion and the buckle.

Further, the insulating rod 2 is a telescopic insulating rod 2.

It should be noted that the insulating rod 2 is provided in a telescopic manner, which facilitates the current tester to detect different lines 5.

Furthermore, the bottom of the insulating rod 2 is sleeved with a silica gel sleeve.

It should be noted that, because the staff need hold the bottom of insulating rod 2 for a long time, the sweat of the outflow of palm of the hand can reduce the frictional force between hand and insulating rod 2 to take place the phenomenon of pine and take place, now through the installation silica gel cover in the bottom of insulating rod 2, can increase the frictional force of staff's hand and insulating rod 2 bottom, avoid taking place the condition of pine and taking off.

Furthermore, a plurality of anti-skidding salient points are arranged on the silica gel sleeve.

It should be noted that the anti-slip salient points are arranged on the silica gel sleeve, so that the friction force between the hand of the worker and the insulating rod 2 can be further enhanced.

Further, the cross section of the insulating rod 2 is hexagonal.

It should be noted that, the rod body of the insulating rod 2 is arranged in the hexagonal prism structure, so that the rolling phenomenon of the traditional cylindrical insulating rod 2 when being laid flat can be avoided.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "including," and "having" are intended to be inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

In contrast, when an element or layer is referred to as being "directly on … …," "directly engaged with … …," "directly connected to" or "directly coupled to" another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship of elements should be interpreted in a similar manner (e.g., "between … …" and "directly between … …", "adjacent" and "directly adjacent", etc.). As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region or section from another element, component, region or section. Unless clearly indicated by the context, use of terms such as the terms "first," "second," and other numerical values herein does not imply a sequence or order. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
