Detailed description of the invention
Test fixture in the relay test system that we use at present be use process through hole on high-temperature insulation block after put into the contact that is made up of two springs to frame mode, solve only exit diameter relay within 1.5mm, and weld the relay exit sizes such as cup type, welding hole formula from 2.5mm～5.5mm, detecting system manufacturer cannot provide applicable interface board, causes the relay of this type of large scale exit cannot test on the detection system, run.
The present invention provides the test fixture of a kind of relay, including: cover plate and printed board, described printed board includes the back side of front and correspondence, and wherein, the vis-a-vis of described cover plate and described printed board is arranged；Also include being positioned at described cover plate and the contact spring of described printed board space, and be positioned at the interface at the described printed board back side.Described contact spring and interface are both secured to described printed board.
Wherein, the test fixture of described relay is for the exit of corresponding described relay, and the positions and dimensions of the exit according to described relay, is accurately positioned described contact spring, is suitable to various sizes of exit.
Further, described interface is unified interface, the test signal of described relay is converted to unified interface by described printed board.Described interface is dual-inline package technical interface (dual inline-pin package, DIP).
The spacing of the welding position of described adjacent contact spring is consistent with the exit external diameter of described relay.Wherein, described contact spring has the projection being positioned at described spring contact pin top, to realize described contact spring and the contact of described relay exit by elastic force produced by described contact spring displacement.The thickness of described contact spring is 0.3 millimeter, and described top projection thickness is 0.5 millimeter.
Further, the stage casing of described contact spring has step, and the insertion hole length that described contact spring is positioned in described printed board is smaller in size than described step dimension.
The general-purpose interface of the fixture of described relay is corresponding with described relay contact group number.Described contact is positioned in described printed board and is designed as the layout that two rows are symmetrical, above two groups of contacts, below two groups of contacts.
Further, including 4 groups of contact general-purpose interfaces, the exit of the relay contact of described 4 groups of contacts is 12.Described exit is for connecting independent voltage and current signal line, and corresponding contact signal line is 12*2=24.
As an embodiment, the present invention, with 4JG-4A as design object, designs the test fixture of a kind of relay, it is possible to meets the test demand welding the large scale exit relays such as cup type, welding hole formula, possesses general test interface.
As it is shown in figure 1, the fixture of the present invention is mainly made up of cover plate 001, contact spring 002, printed board 003, DIP contact pin 004.
The fixture that theres is provided with current equipment manufacturers except that, present invention uses printed board 003, contact spring 002 can be accurately positioned by printed board 003 according to the size of exit position, size, can the exit of compatible various sizes, in addition the versatility of test fixture can be improved very easily by the interface that test signal converting is unified DIP contact pin 004 by the circuit in printed board 003.
At the top of printed board 003, according to the cover plate 001 that the arrangement processing of relay exit is corresponding, the location of exit and guiding when relay inserts.
Further, for ensureing the reliable of contact, contact spring 002 need to provide certain contact force, as an embodiment, the thickness of the contact spring 002 in the present invention can be 0.3mm, top convex 0.5mm, and in printed board 003, to be designed as spacing consistent with exit external diameter in two panels contact spring 002 welding position, utilizing elastic force produced by the spring displacement caused by the convex of contact spring 002 top to realize the reliable contacts of contact spring and exit, contact pressure reaches 0.5N after tested.
In order to ensure the concordance of spring contact position, utilizing the step in contact spring stage casing, the length dimension that contact spring inserts in printed board hole is designed as shorter than step, and contact spring exposes printed board part length after inserting is consistent.
Further, the versatility of fixture is mainly by needing the resource called to determine when testing, and for relay, needs the resource called to be determined by relay contact group number and winding number during test.Conventional relay contact group number has 2 groups, 4 groups, 6 groups, around component unicoil and twin coil.Therefore, the general-purpose interface of fixture is divided into 2 groups, 4 groups, 6 groups by relay contact group number, and winding is unified presses dual coil designs.
The present invention, with the 4JG-4A of 4 groups of contacts as object, designs 4 groups of contact general-purpose interfaces.The exit of the relay contact of 4 groups of contacts totally 12, need to utilize the detection contact point resistance of Kelvin four line Cleaning Principle, each exit need to connect independent voltage, current signal line, corresponding contact signal line is 12*2=24, printed board is designed as the layout that two rows are symmetrical, two groups of contacts above, below two groups of contacts.
Further, the distance of two rows contact pin is designed as 30mm according to the investigation of 4 groups of contact relay sizes, this distance can be common to the relay of other 4 groups of contacts more than the spacing of existing 4 groups of contact relay outermost contacts, the test interface plate therefore made according to this distance.
The present invention is for solving to weld the large scale exit of the relays such as cup type, welding hole formula, the problem that detecting system manufacturer cannot provide applicable interface board so that the relay of this type of large scale exit can be tested on the detection system, run.
