Abstract
The utility model relates to a probe, in particular to a novel large-current probe, The novel large-current probe comprises an external pipe and a middle pipe, wherein the external pipe is internally provided with a helical spring; a pinhead consists of a plurality of copper wires and is pressed at one end of the middle pipe by one step, thus leading contacting points to have large contacting area and small contacting resistance; the other end of the middle pipe is provided with a limiting slot; when the middle pipe is arranged inside the external pipe, the limiting slot is exposed from one end of the external pipe, and a notch can be locked by the limiting slot. The novel large-current probe is characterized in that the pinhead consists of the plurality of copper wires that are pressed at one end of the middle pipe by one step so as to form contacting points, thus leading the contacting points to have large contacting area and small contacting resistance.
Description
Technical field
The utility model relates to a kind of probe, particularly a kind of novel big current probe.
Background technology
The general employing of existing probe holds and in conjunction with helical spring structure, it is contact point that syringe needle adopts the main shaft of a dome, with regard to existing probe technique, if electric current is less, during through contact point, also can not impact the probe life-span; But when probe needed the electric current of larger capacity, current concentration was during by contact point and volute spring, and the easy deterioration of above-mentioned contact point and volute spring causes that also material dissolves or thermal characteristics changes, thereby influenced probe serviceable life.
Summary of the invention
The purpose of this utility model is in order to overcome the defective that existing probe can not bear big electric current, to invent a kind of contact point and adopt many copper wires to make the little novel big current probe of the big resistance of contact area.
The purpose of this utility model realizes as follows: described novel big current probe, comprise outer tube and middle pipe, and the inside of outer tube is provided with volute spring, and syringe needle is made up of several copper wires, of pipe during property is pressed in again; Thereby can make that the big contact resistance of contact area of contact point is little; The other end of middle pipe is provided with stopper slot, and when central pipe was contained in the inside of outer tube, stopper slot can expose from of outer tube, and bayonet socket can be locked by stopper slot.
Described syringe needle is made up of several copper wires, of pipe during property is pressed in again; Form contact point, thereby can make that the big contact resistance of contact area of contact point is little.
Good effect of the present utility model is as follows: when probe needs the electric current of larger capacity, current concentration is during by contact point and volute spring, can not occur that material dissolves or thermal characteristics changes, syringe needle is made up of several copper wires, this structure contacts easily, can super-high-current, can solve the magnitude of current of 500A, increase the serviceable life of probe.

Among the figure, pipe 3 volute springs in 1 outer tube 2
4 syringe needles, 5 stopper slots, 6 bayonet sockets
Embodiment
As shown in Figure 1, described novel big current probe comprises outer tube 1 and middle pipe 2, and the inside of outer tube 1 is provided with volute spring 3, and syringe needle 4 is made up of several copper wires, of pipe during property is pressed in again; Thereby can make that the big contact resistance of contact area of contact point is little; The other end of middle pipe 2 is provided with stopper slot 5, and when central pipe was contained in the inside of outer tube, stopper slot 2 can expose from of outer tube, and bayonet socket 6 can be locked by stopper slot.
Described syringe needle 4 is made up of several copper wires, of pipe during property is pressed in again; Form contact point, thereby can make that the big contact resistance of contact area of contact point is little.
Above-described concrete enforcement only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; also can do some adjustment and improvement, these also should be considered as belonging to protection domain of the present utility model.
