Abstract
The utility model discloses an adapting probe for measurer of printed circuit card. The adapting probe comprises a needle tube with a spring built-in and the top of the frustum of the spring directly interferes with the test probe. The inner of the lower part of the needle tube fixed connects with the conductor with solder. The probe is not only of performance reliability and low failure rate but also very thin and tiny which minimizes the arrangement space of the probes to test the small-sized and the precise printed circuit card.
Description
Technical field
The utility model relates to a kind of printed circuit board test fixture.
Background technology
In the prior art, circuit board is after finishing the line design of several electronic components, must can know just whether the circuit on it has short open circuit conditions through test, and the method for currently used testing circuit board, connecting the circuit test machine by a particular manufacturing craft finishes, this mould upper surface is provided with some probes, probe is provided with corresponding to each pin position of circuit board under test bottom surface, probe base is provided the back stretch that presses down after test is tested by spring, and each probe all need connect conducting to the corresponding jack of winding displacement of circuit test machine with electric wire with needle guard, when testing circuit board, the circuit board under test correspondence is placed on the probe of mould, with after the pin of circuit board under test bottom surface contacts, the circuit test machine can show that the circuit on the circuit board under test has or not short opening circuit by probe.
Present printed circuit board test fixture is made up of pedestal, testing mould two parts, be inserted with test probe on the testing mould, the position of test probe is corresponding with the pin position of circuit board under test, be inserted with the switching probe on the switching mould, the back stretch that presses down after the test is provided for test probe, and be connected with the needle guard lead, pedestal is provided with the ox horn joint that is connected with the lead of needle guard, is connected for establishing with the printed circuit board test machine transplanting of rice.
It is that " CN2493510Y ", name are called the utility model patent of " probe " for " ZL01226677.9 ", notification number that Patent Office of the People's Republic of China discloses a patent No. on June 5th, 2002, this patent disclosure " a kind of probe; be equipped with in combined tester; be positioned at the corresponding position of each pin of circuit board under test; this probe comprises: a bottom has the needle body of Plug Division; and an end connects the spring of establishing lead; this needle body be arranged in the tool and be positioned at spring directly over, its Plug Division then is in contact with one another conducting with the spring top; Wherein, this spring top is the backing portion that holding in the palm of one coiling and molding caught the Plug Division, design whereby, and the jacking block that then need not the additional processing manufacturing supports can reduce manufacturing cost.”
Though the probe of this patent has been save sleeve pipe and tray in the spring outside, has reduced cost, but exist following shortcoming in actual use:
1. because spring directly places the switching mould, and this spring top is provided with spill backing portion and pegs graft for test probe, spring and hole wall, test probe and the spring of switching mould are easy to be stuck and can not reply during test, cause test probe not contact, make the printed circuit board test machine send wrong test result with the pin of circuit board under test.
2. along with development of electronic technology, printed circuit board (PCB) is miniature precisionization more and more also, this just requires test probe to want spacing thin, probe little, and that the probe in the above-mentioned patent can not be accomplished is very thin, because very thin probe can fall into the center pit of spring, and spring can not be accomplished very thin because its top has spill backing portion, and coil spring has after the probe extruding and extends out phenomenon, makes probe and spring stuck.
Since below, the switching mould that plugs spring and above, have the relative position error between the testing mould that plugs test probe, so the bottom of probe can not be plugged into the backing portion center of spring upper end very exactly, thereby the easier probe that makes is stuck or subside phenomenon with the spring generation.
4. in the prior art,, there is no any coating protection, when Mould Machining and maintenance, easily spring is caused distortion and damage because spring is exposed fully outside.
Summary of the invention
The purpose of this utility model is: a kind of switching probe of printed circuit board test fixture is provided, and this probe not only dependable performance, failure rate is low, and can accomplish very thin very little, to reduce the arrangement pitches of probe, the printed circuit board (PCB) of test miniature precisionization.
The technical solution of the utility model is: a kind of switching probe of printed circuit board test fixture, and comprise needle tubing, place the spring in the needle tubing, the direct and test probe conflict in the upper end of described spring, the bottom and the lead of needle tubing are connected and fixed.
The further technical scheme of the utility model is: a kind of switching probe of printed circuit board test fixture, and comprise needle tubing, place the spring in the needle tubing, the direct and test probe conflict in the upper end of described spring, the bottom and the lead of needle tubing are connected and fixed; The upper and lower of described spring is the driving fit district, the middle part is the springing stroke district, and driving fit district in top is the frustum shape, frustum top and test probe conflict.
The more detailed technical scheme of the utility model is: a kind of switching probe of printed circuit board test fixture, and comprise needle tubing, place the spring in the needle tubing, the direct and test probe conflict in the upper end of described spring, the bottom and the lead of needle tubing are connected and fixed; The upper and lower of described spring is the driving fit district, the middle part is the springing stroke district, and driving fit district in top is the frustum shape, frustum top and test probe conflict; The bottom of described needle tubing is provided with the bottom that a circle groove is held spring; The outer wall of described needle tubing is provided with the stuck point of several indents, and the driving fit district, bottom that stuck point snaps in spring is provided with in the circle depression; Be connected and fixed with scolding tin and lead in the lower tube of described needle tubing.
The utility model has the advantages that:
1. the utility model places needle tubing with spring, and spring can stuck fault not take place with the switching mould during test, and the test probe on the probe top of can guaranteeing to transfer contacts well with the circuit board under test pin, and has reliable back stretch.
The utility model with the upper and lower of spring turn to the driving fit district, the middle part turns to the stroke district, direct and the test probe conflict in the top of spring, so spring and test probe all can be done very tinyly, to dwindle the arrangement pitches of probe, the printed circuit board (PCB) of test miniature precisionization.
3. the syndeton of directly conflicting rather than inserting between spring of the present utility model and the test probe can remedy the site error between test probe and the switching probe, can guarantee that test probe contacts well with the switching probe, and can not produce stuck phenomenon.
