Description

The megger test anchor clamps
Technical field
The present invention relates to the proving installation of electronic devices and components, particularly a kind of megger test anchor clamps.
Background technology
Megger test is the insulated part of measuring electronic devices and components, is adding under the DC voltage of regulation, owing to the insulation imperfection produces the resistance that leakage current forms.The insulating property of determining components and parts whether the coincidence circuit design requirement or when standing the environmental stresses such as high temperature is moist, whether its insulation resistance meets the regulation of related standards.
Usually test the insulation resistance of various Cans with Insulation Resistance Tester, what conventional Insulation Resistance Tester adopted is the crocodile clip port of traditional type, it is the pipe leg that directly touches tested Can with crocodile clip during test, this method of testing is inconvenient to operate because surface of contact is relatively more loosening, press from both sides different site tests result differences bigger than normal, thereby can't test accuracy and the usable range that affects megger test to the little device of pin-pitch.
Find through retrieval: the patent No. is CN200310100278.8, name is called open type testing clamp for circuit board, anchor clamps by two tandems slidably 62 channel standard twin-string sockets constitute test interface, select a socket to link to each other as test access with each passage of standard twin-string socket respectively by 124 two that are installed on the insulcrete, when adaptive two select the plug of a socket not insert, standard twin-string socket passage and I/O form path, when adaptive two selected the plug insertion of a socket, the passage that standard twin-string socket passage is connected with this plug formed path.
Another patent No. is 200920110359.9, name is called a kind of fast insulation test device, comprise printed board, the two switches of putting of several hilted broadswords, connection terminal and socket, socket has and the two identical jacks of number of switches of putting of hilted broadsword, several hilted broadswords are two puts switch and socket all is welded in the printed board, two one of them contact of putting switch of all hilted broadswords are connected on another terminal of connection terminal after printed board is compiled in a bit, the two intermediate contacts of putting switch of each hilted broadsword link to each other one by one with each jack of socket, each jack of socket connects measurand, and two end points of connection terminal connect megger test equipment.Above two patents all are not suitable for the megger test of circuit contact pin type pin.
Summary of the invention
Purpose of the present invention is exactly the shortcoming that is not suitable for clamping circuit contact pin type pin that exists in order to solve existing test fixture, a kind of megger test anchor clamps that provide.
The technical solution used in the present invention is as follows:
A kind of megger test anchor clamps comprise base plate, it is characterized in that:
A, base plate middle part are provided with two general dual-in-line sockets;
B, base plate are provided with two switches set, are respectively equipped with one group of toggle switch in each switches set;
One end of c, each toggle switch links to each other with total wire with the corresponding connection of intermediate plate on the corresponding general dual-in-line socket, the other end of each toggle switch respectively, and the output terminal of total wire is connected with accessory power outlet by resistance R.
On the basis of technique scheme, the technical scheme of further optimization can be arranged:
Be provided with two extra switch groups at base plate, be respectively equipped with one group of toggle switch in each extra switch group, an end of each toggle switch links to each other with total wire with the corresponding connection of intermediate plate on the corresponding general dual-in-line socket, the other end of each toggle switch respectively.
Among the present invention: described base plate can be selected pcb board, described general dual-in-line socket is known products, can insert different jacks according to the big or small lead leg spacing of shell regulates, two mechanical handle are depressed, clamping socket both sides copper intermediate plate, thereby the pipe leg on the clamping shell is realized being connected of a certain pipe leg and output terminal.The resistance that has added a 1M Ω at the output terminal of anchor clamps can play certain protection operation to anchor clamps, and the megger test data are also more accurate, and is stable.
 
The present invention is by the little toggle switch of each output terminal, like this can be more succinct, easily and fast test out insulation resistance, tester is connected the long pin crocodile clip of employing modified with anchor clamps, the cylindrical connecting hole wringing fit of leg insertion anchor clamps is clamped rear assurance and can not become flexible.The present invention compares present test mode and has greatly improved testing efficiency, can carry out megger test to different types of Can by the socket of changing different model, has diversity and versatility.
