Embodiment one:
As shown in Figure 1 to Figure 3, the utility model embodiment one provides a kind of tool, include dials 1, drum 2, test interface 3 and many position-limited needles 4, and spaced one end penetrates drum 2 connects one to one in a detachable fashion with many position-limited needles 4, the other end is connected with test interface 3 many conductor wires 5.Described many position-limited needles 4 interval can be interted in dials 1 with arranging up and downly, and every bar position-limited needle 4 includes needle body 41, described needle body 41 is provided with spacing male part 42, described spacing male part 42 is flat outer projections, this flat outer projection can be that employing instrument flattens formation on needle body 41, one-body molded with needle body 41, and between the insulcrete and dials base plate of dials 1; Concrete structure can be: described dials 1 includes the dials face 11, dials second insulcrete 12, guiding insulcrete 13 and the dials base plate 15 that are fixed as one successively from top to bottom; Described spacing male part 42 is located at the close lower end of needle body 41, and can be stuck between guiding insulcrete 13 and dials base plate 15 up or down; One end that every bar conductor wire 5 is connected with position-limited needle 4 is provided with back-moving spring 51, and lower end and the conductor wire 5 of described back-moving spring 51 are connected and fixed, and upper end contacts with the lower end of position-limited needle 4 and connects; Described position-limited needle 4 is metal needles, and described conductor wire 5 is enameled wire or OK line.
When adopting tool described in the utility model to test, circuit board under test 6 is placed on dials face 11, the pressure that position-limited needle 4 on dials face 11 is subject to circuit board under test 6 moves down, make to be connected with the upper-end contact of the lower end of position-limited needle 4 with back-moving spring 51, back-moving spring 51 forced contraction, now the spacing male part 42 of position-limited needle 4 is stuck on dials base plate 15; On the contrary, when the test is finished, circuit board 6 is taken out from dials face 11, position-limited needle 4 moves up under the restoring force effect of back-moving spring 51, its spacing male part 42 is stuck in and guides on insulcrete 13, and now the lower end of position-limited needle 4 is still kept in touch with back-moving spring 51 and connected or to be tricklely separated.
Like this, by arranging spacing male part 42 being positioned on the position-limited needle 4 between insulcrete and dials base plate (namely guiding insulcrete 13 and dials base plate 15), can limit the scope that moves up and down of position-limited needle 4, avoid position-limited needle 4 reset under the effect of back-moving spring 51 excessively thus make its lower end away from back-moving spring 51, when causing once testing on carrying out, pressurized moves down process and very easily departs from and cannot contact with back-moving spring 51 and connect or contact link position and offset, position-limited needle 4 is caused to bend, distortion, the problem even damaged, stable work in work, reliably, long service life, greatly can reduce the scrappage of testing circuit board simultaneously, and structure is very simple, practical, be easy to processing.
Certainly, described spacing male part 42 also can be that evagination endless belt (if spacing male part 42 is set in sleeve pipe on needle body 41, needle body 1 forms evagination endless belt.) or the outer projection of annular array.Size, the length of described needle body 1 and spacing male part 42 can freely make according to actual needs.
Embodiment two:
As shown in Figure 4, the utility model embodiment two provides a kind of tool, its structure is substantially identical with embodiment one, include dials 1, drum 2, test interface 3 and many position-limited needles 4, and spaced one end penetrates drum 2 connects one to one in a detachable fashion with many position-limited needles 4, the other end is connected with test interface 3 many conductor wires 5.Described many position-limited needles 4 interval can be interted in dials 1 with arranging up and downly, and every bar position-limited needle 4 includes needle body 41, described needle body 41 is provided with spacing male part 42, one end that every bar conductor wire 5 is connected with position-limited needle 4 is provided with back-moving spring 51, lower end and the conductor wire 5 of described back-moving spring 51 are connected and fixed, and upper end contacts with the lower end of position-limited needle 4 and connects.Its difference is only, described spacing male part 42 is between two insulcretes of dials 1; Concrete structure can be: described dials 1 includes the dials face 11, dials second insulcrete 12, guiding insulcrete 13 and the dials base plate 15 that are fixed as one successively from top to bottom; Described spacing male part 42 is located at the close lower end of needle body 41, and can be stuck in dials second insulcrete 12 up or down and guide between insulcrete 13.
Like this, by arranging spacing male part 42 being positioned on the position-limited needle 4 between two insulcretes (i.e. dials second insulcrete 12 and guide insulcrete 13), can limit the scope that moves up and down of position-limited needle 4 equally, it also avoid position-limited needle 4 reset under the effect of back-moving spring 51 excessively thus make its lower end away from back-moving spring 51, when causing once testing on carrying out, pressurized moves down process and very easily departs from and cannot contact with back-moving spring 51 and connect or contact link position and offset, position-limited needle 4 is caused to bend, distortion, the problem even damaged, stable work in work, reliably, long service life, the scrappage of testing circuit board is low, and structure is simple equally, practical, be easy to processing.
Certainly, described spacing male part 42 also can be arranged on the needle body 41 between other two insulcrete of dials 1.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
