Abstract
The utility model relates to a dedicated contact probe of an electrical characteristic test stand of a circuit breaker. The dedicated contact probe comprises an electrode rod, a shaft sleeve, upper and lower shaft sleeve covers, a spring and a positioning ring. One end side of the electrode rod is with a screw thread. The positioning ring is fixedly connected to a position, wherein the distance from the position to the other end is a third of the length of the electrode rod. The spring is sleeved on the electrode rod. One end of the spring abuts against the positioning ring and the other end is connected with one end of the lower shaft sleeve cover which sleeves on the electrode rod. The other end of the lower shaft sleeve cover is connected with a nut on the electrode rod screw thread. An annular groove on the shaft sleeve is clamped and fixed with the groove of the upper shaft sleeve cover and then is sleeved on the electrode rod. A lower annular groove of the shaft sleeve is clamped and fixed with the groove of the lower shaft sleeve cover on the electrode rod. The contact probe can bear a pressure which is greater than 100g and a service life is long. An expansion amount which is greater than 30mm is possessed and various types of circuit breakers can be fully contacted. An electrode diameter is large and a current which is higher than 5 amperes can be detected. Mechanical strength of the contact probe is the same as the mechanical strength of a shaft bushing whose diameter is about 6mm. The contact probe has the advantages that the structure is simple; cost is low; operation is simple and so on.
Description
Technical field
The utility model belongs to the electric attribute testing platform of a kind of isolating switch special purpose parts, particularly relates to a kind of special-purpose contact probe of testing table that is used for realizing with the electric characteristic of isolating switch of multiple different model isolating switch good contact function.
Background technology
At present mostly the known contact device that is applied to detect the testing table of the electric characteristic of isolating switch is to use contact probe.Use contact probe partly to contact with the metal of isolating switch, formation loop, and then various electrical specifications that can the test both opens device.See with regard to present circumstances, the length of contact probe own is short, and scalable amount is smaller, and the isolating switch scope of the different model that can be suitable for is narrow; This body structure of contact probe is thinner, can not bear when the switch divide-shut brake, and the impulse force that brings causes the serviceable life of probe shorter; The diameter of contact probe electrode is smaller, can not bear the large electric current in the circuit.If this moment is just simply required according to test, improve the material of contact probe, not only performance does not improve too much, but also can cause resource, material and temporal waste, has increased widely on the contrary cost.
Summary of the invention
The utility model provides the special-purpose contact probe of testing table of the electric characteristic of a kind of isolating switch for solving the technical matters that exists in the known technology.
The utility model for the technical scheme that solves the technical matters that exists in the known technology and take is: it include length be 100-200 millimeter, diameter be the electrode stem, axle sleeve of 2-3 millimeter, with upper Lower shaft sleeve lid, spring and the locating ring of center pit; One distolateral being threaded of described electrode stem is fixed with described locating ring being about described electrode stem length 1/3rd places apart from its other end; The described spring that internal diameter and described electrode stem external diameter are complementary is set on the described electrode stem, and described electrode stem still can be freely movable in described spring; An end that is set on the described spring on the described electrode stem leans on described locating ring, the described spring other end contacts with an end that is enclosed within the described lower shaft upper shield on the described electrode stem by the threaded side of described electrode stem, and the nut that the other end of described lower shaft upper shield and is tightened on the described electrode stem screw thread is abutted against mutually; The upper end of described axle sleeve one on the groove that covers of annular groove and described Upper shaft sleeve each other after the friction tight fixing together, the end that is fixed with locating ring one side by described electrode stem again is set on the described electrode stem, and the lower annular groove of described axle sleeve lower end and the described Lower shaft sleeve groove that has been enclosed within the lower shaft upper shield on the described electrode stem each other wringing fit fix together.
Advantage and the good effect that the utlity model has are: this contact probe can bear the pressure greater than 100g, and can be arranged long serviceable life; Stroke greater than 30mm is arranged, can contact fully the isolating switch of Multiple Type; Electrode diameter is enough large, can detect to be higher than 5 amperes electric current; It is enough thick pipe spreader about 6mm that diameter is arranged, and physical strength is good, can bear larger impulsive force.The common contact probe of comparing, also have simple in structure, cost is low, the remarkable advantage such as easy to operate.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
Shown in Fig. 1,2,3,4,5, length be 120 millimeters, diameter be 2.5 millimeters electrode stem 1 one distolaterally be threaded 5, be that 1/3rd places are welded with locating ring 2 in distance electrode bar other end length; The spring 3 that internal diameter and electrode stem 1 external diameter are complementary is set on the electrode stem 1, and electrode stem 1 still can be interior freely movable at spring 3; An end that is set on the spring 3 on the electrode stem 1 leans on locating ring 2..With center pit 11,13 upper and lower axle sleeve lid 6,7, upper and lower axle sleeve lid 6,7 can be set on the electrode stem 1 by center pit 11,13 respectively.Spring 3 other ends contact with an end that is enclosed within the lower shaft upper shield 7 on the electrode stem by electrode stem 1 threaded 5 one sides, and the nut 4 that the other end 9 and of lower shaft upper shield 7 is tightened on electrode stem 1 screw thread is abutted against mutually; The upper end of axle sleeve 8 one on groove 12 on annular groove 16 and the Upper shaft sleeve lid 6 each other after the friction tight fixing together, end by locating ring 2 one sides of electrode stem 1 is set on the electrode stem 1 again, and the lower annular groove 17 of axle sleeve 8 lower ends and the Lower shaft sleeve groove 14 that has been enclosed within the lower shaft upper shield 7 on the electrode stem 1 each other wringing fit fix together.
The length of electrode stem 1 can adopt 100 millimeters according to actual needs until 200 millimeters.And the diameter of electrode stem also can adopt 2 millimeters to 3 millimeters according to the test current actual needs.
