Description

Insulation resistance test clamp
Technical field
The present invention relates to the proving installation of electronic devices and components, particularly a kind of insulation resistance test clamp.
Background technology
Megger test is the insulated part measuring electronic devices and components, under the DC voltage of additional regulation, and the resistance formed because insulation imperfection produces leakage current.When determining the insulating property requirement whether coincidence circuit designs of components and parts or stand the environmental stresses such as hot humid, whether its insulation resistance meets the regulation of related standards.
Usually the insulation resistance of various Can is tested with Insulation Resistance Tester, the crocodile clip port of what conventional Insulation Resistance Tester adopted is traditional type, it is the pipe leg directly touching tested Can with crocodile clip during test, this method of testing is inconvenient to operate because surface of contact relatively loosens, press from both sides different site tests result differences bigger than normal, the device little on pin-pitch cannot be tested thus affect accuracy and the usable range of megger test.
Find through retrieval: the patent No. is CN200310100278.8, name is called open type testing clamp for circuit board, fixture by two tandems slidably 62 channel standard twin-string sockets combine form test interface, a socket is selected to be connected as test access with each passage of standard two-row socket respectively by 124 two that are arranged on insulcrete, when adaptive two select the plug of a socket not insert, standard two-row receptacle channel and I/O form path, when adaptive two select the plug of a socket to insert, the passage that standard two-row receptacle channel is connected with this plug forms path.
Another patent No. is 200920110359.9, name is called a kind of fast insulation test device, comprise printed board, several hilted broadswords are two puts switch, connection terminal and socket, socket has puts the identical jack of number of switches with hilted broadsword pair, switch put by several hilted broadswords pair and socket is all welded in printed board, two one of them contact of putting switch of all hilted broadswords is compiled in a bit and is connected on another terminal of connection terminal in printed board, each jack of each hilted broadsword two intermediate contact and socket of putting switch is connected one by one, each jack of socket connects measurand, two end points of connection terminal connect megger test equipment.Above two pieces patent is all not suitable for the megger test of circuit contact pin type pin.
Summary of the invention
Object of the present invention is exactly the shortcoming being not suitable for clamping circuit contact pin type pin existed to solve existing test fixture, a kind of insulation resistance test clamp provided.
The technical solution used in the present invention is as follows:
A kind of insulation resistance test clamp, comprises base plate, it is characterized in that:
Two general dual-in-line sockets are provided with in the middle part of a, base plate;
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 is corresponding with the intermediate plate on corresponding general dual-in-line socket respectively to be connected, the other end of each toggle switch is connected with total wire, 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 optimized further can be had:
Base plate is provided with two extra switch groups, be respectively equipped with one group of toggle switch in each extra switch group, one end of each toggle switch is corresponding with the intermediate plate on corresponding general dual-in-line socket respectively to be connected, the other end of each toggle switch is connected with total wire.
In the present invention: described base plate can select pcb board, described general dual-in-line socket is known products, different jack can be inserted according to the size lead leg spacing of shell to regulate, two mechanical handle pressures, clamping socket both sides copper intermediate plate, thus the pipe leg on clamping shell, realize the connection of a certain pipe leg and output terminal.Add the resistance of a 1M Ω at the output terminal of fixture, can play certain protection operation to fixture, megger test data are also relatively accurate, stable.
The present invention is by the little toggle switch of each output terminal, insulation resistance can be tested out more succinctly, easily and fast like this, tester is connected with fixture and adopts the long pin crocodile clip of modified, and the cylindrical connecting hole wringing fit that a leg inserts fixture is clamped rear guarantee and can not be loosened.The present invention compares present test mode and substantially increases testing efficiency, can carry out megger test, have diversity and versatility by the socket changing different model to different types of Can.
Accompanying drawing illustrates:
Fig. 1 is structure principle chart of the present invention.
