Abstract

A lead of an electricity meter used for measuring relates to an electronic measuring instrument. The invention provides the lead that can prevent a probe from detaching a measuring point, which comes from the vibration of a finger. The lead consists of the probe and a handle. The back end of the probe is provided with a double wedge. The double wedge is fixed on a tube. A spring is arranged in the tube. The spring rests against the tail end of the probe forwardly. The tube wall of the spring is connected with a measuring wire. When the finger vibrates, owing to the buffer of the probe and the spring of the probe, the probe gets very close to the measuring point. Therefore, the lead of the electricity meter is applicable to various electricity meters used for measuring.

Description

Measure the table rod of the ammeter of purposes

Technical field

This case relates to electronic measuring instrument.

Background technology

The probe of common table rod all is the rigid handle inside that is fixed on, and finger is shaken slightly to pop one's head in and will be left measurement point during measurement, is easy to cause the error of opening circuit.

Summary of the invention

This case technical matters to be solved is that a kind of table rod that finger shake probe breaks away from measurement point of eliminating is provided.In order to solve the technical problem, the technical scheme of this case is to be made up of probe and handle thereof, it is characterized in that there is double wedge the rear end of described probe, double wedge is fixed on crimping place in the pipe that contains spring, spring props up the tail end of probe forward, and the outer wall wall of pipe joins with the measurement electric wire.When shake finger because the buffering of probe and spring thereof, thereby, probe is adjacent at measurement point.

Described probe and spring thereof and pipe, the probe that can adopt the circuit board system test to use directly is welded on handle inside with probe.

Description of drawings

Below in conjunction with the drawings and specific embodiments this case is described in further detail.

As figure, this case

Embodiment

As figure, the tail end of probe 1 is by spring 2, and the tail end of probe 1 and spring are fixed on the inside of pipe 3, and the outer wall of pipe 3 connects electric wire 4.

As figure, table rod probe 1 and handle 2 thereof are formed, and there is double wedge 3 rear end of probe 1, and double wedge 3 is fixed on crimping 6 places in the pipe 5 that contains spring 4, and spring 4 props up the tail end of probe 1 forward, and the outer wall of pipe 5 is stuck in handle 2 inside, the outer wall of pipe 5 with measure electric wire 7 and join.Handle 2 can adopt left and right sides integrated structure commonly used also can use the front and back sleeve structure of common table rod always.

Above feature is otherwise combined according to actual needs.

Claims

1. measure the table rod of the ammeter of purposes, be made up of probe and handle thereof, it is characterized in that there is double wedge the rear end of described probe, double wedge is fixed on crimping place in the pipe that contains spring, and spring props up the tail end of probe forward, and the outer wall wall of pipe joins with the measurement electric wire.
