Description

Technical Field

[0001] The utility model relates to the technical field of conductive connection, in particular to a current needle. Background Art

[0002] The current needle is also called the current probe. With the development of the times, people's scientific and technological level is constantly improving, and the use of electricity is becoming more and more extensive. In order to facilitate people to operate power equipment, current needles are often installed inside power institutions. With the popularization of power equipment, the demand for the use of current needles has also increased accordingly, so a current needle is needed.

[0003] When the existing current probe is in use, the probe is generally inserted into the hole. When the current needle is not aligned with the hole, the probe cannot be protected. When the probe is not aligned with the hole, it is impossible to prevent the current needle from being continuously subjected to force, resulting in damage to the current needle. Utility Model Content

[0004] The present invention aims to provide a current probe to address the problems of the prior art, namely, that the current probe cannot provide protection when the probe is not aligned with the socket, and that the current probe cannot be protected from continuous force when the probe is not aligned with the socket, resulting in damage to the current probe. To achieve the above-mentioned purpose, the present invention provides the following technical solution: a current probe comprising an outer tube frame, a mounting tube fixedly connected to the bottom of the outer tube frame, a telescopic assembly disposed within the outer tube frame, a positioning assembly disposed on one side of the outer tube frame, the telescopic assembly comprising a movable circular groove disposed within the outer tube frame, an extension spring fixedly connected thereto, a through-hole disposed at the bottom of the inner wall of the movable circular groove, a correction inner tube mounted on the top of the extension spring, a probe body movably connected thereto, one end of the probe body extending through the through-hole to the bottom of the through-hole, a contact square groove disposed within the mounting tube, a return spring fixedly mounted thereto, a limit square plate mounted on the top of the return spring, a threaded hole disposed therein.

[0005] Further preferably, the telescopic assembly also includes a limit block, which is fixedly connected to the bottom of the correction inner tube, and the probe body is threadedly connected to the inside of the limiting square plate. By installing the telescopic assembly, when the current needle is not aligned with the socket, the correction inner tube can protect the probe body. At the same time, the correction inner tube is sleeved on the outside of the probe body and can be telescoped up and down, and can straighten the bent probe body. Then the internal reset spring enables the probe body to be telescoped within a certain range, and the probe body can be replaced through the threaded hole in the limiting square plate. The design of the double telescopic structure avoids the current needle from being continuously subjected to force when it is not aligned with the socket, causing damage to the current needle, thereby improving the life of the current needle.

[0006] Further preferably, the positioning assembly includes a positioning plate, which is fixedly connected to the side surface of the outer tube frame, and the side surface of the positioning plate is fixedly connected to a positioning block, a positioning hole is opened inside the positioning block, and the internal thread of the positioning hole is connected to a positioning bolt, and the bottom of the positioning plate is fixedly connected to a gasket layer. By installing the positioning assembly, the current needle can be installed on the device using the mounting tube, and the positioning plate is fitted with the surface of the device, and then the current needle is positioned by the positioning bolt in the positioning block, so that it will not rotate during subsequent use, thereby improving practicality.

[0007] Further preferably, a contact chamber is provided inside the mounting tube, a conductive block is fixedly connected to the inside of the contact chamber, a contact groove is provided on the top of the conductive block, and the bottom of the probe body is adapted to the contact groove. By installing the contact chamber, the conductive block with better electrical conductivity can be used as a support for the probe body. When the probe body is inserted into the hole, the bottom of the probe body can be fitted into the contact groove due to the extrusion of the top to connect the circuit, thereby improving practicality.

[0008] Further preferably, a connection head is fixedly connected to the bottom of the conduction block, and a mounting thread is provided on the side surface of the mounting tube. By installing the connection head, the contact surface of the connection head can be increased, thereby improving the conductivity of the current.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In the present invention, by installing the telescopic assembly, when the current needle is not aligned with the socket, the correction inner tube can protect the probe body. At the same time, the correction inner tube is sleeved on the outside of the probe body and can be extended and retracted up and down, and the bent probe body can be straightened. Then the internal reset spring enables the probe body to be extended and retracted within a certain range, and the probe body can be replaced through the threaded hole in the limiting square plate. The design of the double telescopic structure avoids the current needle from being continuously stressed when it is not aligned with the socket, which may cause damage to the current needle, thereby improving the service life of the current needle.
