Background technology
In automobile navigation instrument production run, carrying out test to the circuit board in automobile navigation instrument is very important work.
In prior art, for the circuit board of small serial production, being generally directly use the electric current and voltage on multimeter testing circuit board between two measurement points, whether qualifiedly carrying out decision circuitry plate, there is the inefficient shortcoming of test job in this method of testing.
And for the circuit board produced in enormous quantities, in prior art, the general circuit board testing instrument that adopts utilizes software program automatically to detect.Its using method is, each test point on circuit board is connected with the signal input part on circuit board testing instrument, and run the test procedure in computer, test result is shown by computer monitor, and non-defective unit just shows OK, badly just shows NG.But adopt circuit board testing instrument testing circuit plate, need check point each on circuit board to be connected with the signal input part on tester simultaneously, and in prior art, also do not have good method to be connected with each test point on circuit board by circuit board testing instrument fast.
Utility model content
In view of this, the purpose of this utility model is to provide the quick test fixture of a kind of circuit board, can not fast by problem that circuit board testing instrument is connected with each test point on circuit board to solve in prior art.
The quick test fixture of this practical circuit plate, comprise base plate, described base plate is provided with and the circuit board vertically location-plate that coordinates of grafting, described base plate is also provided with left straight guide and right straight guide, described left straight guide and right straight guide lay respectively at the both sides of location-plate, described left straight guide is provided with the left probe base be slidably matched with it, described left probe base is provided with the left probe groups of check point on connecting circuit board left surface, described right straight guide is provided with the right probe base be slidably matched with it, described right probe base is provided with the right probe groups of check point on connecting circuit board right flank,
Also comprise the left push rod promoting left probe base and slide along left straight guide, described base plate is provided with the left ram seat with left push rod threaded engagement;
Also comprise the right push rod promoting right probe base and slide along right straight guide, described base plate is provided with the right ram seat with right push rod threaded engagement.
Further, described location-plate is U-board, the U-lag wall of location-plate is provided with the locating slot coordinated with circuit board sliding plug.
The beneficial effects of the utility model:
The quick test fixture of the utility model circuit board, before use, in advance the left end of left probe groups is connected with circuit board testing instrument with the right-hand member of right probe groups, then circuit board is plugged on location-plate, then promote left and right probe base by left and right push rod to move along guide rail, under the guide effect of straight guide, can ensure that left probe groups and right probe groups can accurately with the check point on circuit board left and right side just to being connected, and apply pressure by push rod, can ensure that probe contacts with check point well; Circuit board detecting point can be realized quick and precisely to be connected with circuit board testing instrument by this frock, raising circuit board detecting speed that can be very large.
Accompanying drawing explanation
Fig. 1 is the structural representation of the quick test fixture of the utility model circuit board;
