In order better to prevent that pressure spring 5 is from the interior ejection of spring fixed column 3, the inwall of spring fixed column 3 second ends is provided with internal screw thread, and the outside surface of end cap of the spring 7 leading sections is provided with the external screw teeth matching with internal screw thread, and internal screw thread is threaded with external screw teeth.As preferably, the rear end that connects motion bar 2 penetrates the pressure spring 5 that is arranged in the first through hole, wherein one end of pressure spring 5 is connected to and connects on motion bar 2, and like this, connection motion bar 2 penetrates the deformation that the part in pressure spring 5 is pressure spring 5 provides guide effect.Wherein, connect motion bar 2 can be designed to " in " font, upper part penetrates in pressure spring 5, lower end connects product and presses key head 1, wherein one end of pressure spring 5 is connected to middle part.
In Fig. 1 or 2, spring fixed column 3 is stepped, after can regarding two different right cylinders of bottom surface diameter as and being connected as a single entity, forms, and inside is provided with columniform the second through hole vertically, makes spring fixed column 3 be hollow state, and two ends also have circular open; Pressure spring 5 is arranged in the second through hole, be " in " connection motion bar 2 rear ends of font penetrate in pressure spring 5, front end stretches out and connects product by key head 1 from the second through hole, pressure spring 5 wherein one end is connected to the middle part that connects motion bar 2, product designs according to customer specifications book by the size of key head 1 and material, connecting motion bar 2 can slidably reciprocate along the second through hole, and while connecting motion bar 2 motion, pressure spring 5 produces deformation thereupon in the second through hole; End cap of the spring 7 leading sections are threaded in the second end of spring fixed column 3, to block the second through hole, and the other end of Bonding pressure spring 5, like this, can be not out in second through hole of pressure spring 5 in spring fixed column 3; Handle is fixedly connected on the rearward end of end cap of the spring 7 by key head 9, between handle is by key head 9 and upper limit plate 6, fill support spring 8, support spring 8 is enclosed within the rearward end of end cap of the spring 7, the leading section of one end linking springs plug 7, other end connecting handle is pressed key head 9, the effect of support spring 8 is to make a whole set of button assembly 10 when not being subject to external force, can not travel forward because of gravity reason, and button assembly 10 only just can travel forward when being subject to pressed by external force; A whole set of button assembly 10 is contained between lower limiting board 4 and upper limit plate 6, and lower limiting board 4 is the proal strokes of restriction button assembly 10, and upper limit plate 6 is strokes that restriction button assembly 10 moves backward; The structural representation of upper limit plate 6 please refer to Fig. 5 and 6, upper limit plate 6 is rectangular-shaped, inside offers spacing groove 61, the end face of spacing groove 61 is U-shaped, the structural representation of lower limiting board 4 please refer to Fig. 3 and 4, and it is rectangular-shaped that lower limiting board 4 is also, and inside offers the second through hole, the second through hole can be regarded two different cylindrical holes 41 and 42 of bottom surface diameter as and be connected as a single entity and form, and the diameter of first end end face is greater than the diameter of the second end end face.When test, the second through hole of the spacing groove 61 of upper limit plate 6 and lower limiting board 4 is communicated with, and the second end of spring fixed column 3 can only be moved in spacing groove 61 and in the space that in the second through hole, diameter is larger.
While starting to test, according to the test specification of film key, fix the position of upper limit plate 6 and lower limiting board 4, button assembly 10 is packed between upper limit plate 6 and lower limiting board 4 as Fig. 1, handle is subject to outside applied pressure by key head 9, from Fig. 1, pressure straight down, setting handle is the place ahead by the direction of the suffered pressure indication of key head 9, external pressure has comprised cylinder, all external pressures that motor or manual etc. applies, button assembly 10 externally starts to travel forward under the effect of pressure, the external diameter of support spring 8 is greater than the width of spacing groove 61U type end side, thereby can not move in the spacing groove 61 of upper limit plate 6, but be stuck in outside spacing groove 61, now support spring 8 is constantly compressed, spring fixed column 3 will travel forward along spacing groove 61 and the second through hole.After button assembly 10 motion certain distances, product starts to contact the film key in printed wiring board or flexible circuit board by key head 1, continue to apply external pressure, button assembly 10 moves forward, the compressed beginning deformation of pressure spring 5, the stroke of its deformation is determined by lower limiting board 4, because the second end end face diameter of the second through hole is greater than the diameter of spring fixed column 3 second end end faces, the second end of spring fixed column 3 moves in the space that in the second through hole, diameter is larger gradually, along with the compression set of pressure spring 5 is increasing, the space that in second end distance the second through hole of spring fixed column 3, diameter is less is more and more nearer, when button assembly 10 moves to the extreme position of lower limiting board 4, the intersection in the space that the extreme position of so-called lower limiting board 4 space that namely diameter is larger in the second through hole and diameter are less, the diameter that is less than spring fixed column 3 second end end faces due to the first end face diameter of the second through hole is greater than the diameter of spring fixed column 3 first end end faces, the first end of spring fixed column 3 can move in the space that in the second through hole, diameter is less, the second end of spring fixed column 3 is stuck in intersection, cannot continue motion, now, the deformation of pressure spring 5 is also just fixed, the suffered power of product button is also just determined thereupon, therefore, as long as set the position of lower limiting board 4, each suffered power of film key is all constant, also be in the stressed scope of product button, the size of extraneous power is stressed just without impact on product button institute.When handle is not subject to external force by key head 9, button assembly 10 will be subject to the pulling force of support spring 8, on move on to the extreme position of upper limit plate 6, here because spacing draw-in groove is less than the diameter of spring fixed column 3 second end end faces near one end groove width of end cap of the spring 7 rearward end, under the restriction of upper limit plate 6, spring fixed column 3 can not be drawn out lower limiting board 4 and upper limit plate 6.Button assembly 10 moves reciprocatingly always like this, the batch testing of testing film button.
In this embodiment, on the one hand, the mechanism structure of Ding Liding stroke test film key is simple, takes up room little, is easy to regulate and install.On the other hand, during film key on test printed circuit board or flexible PCB, by the deformation stroke of pressure spring 5 in button assembly 10, control the size of pressure on film key, extraneous no matter be to apply in which way external pressure, also no matter the external pressure applying has much, on film key, suffered pressure is all constant, as long as the test specification book providing according to client before design, set the position of lower limiting board 4, and then control the deformation stroke of pressure spring 5 well, pressure suffered on film key has also just been determined, thereby guarantee that each printed circuit board or flexible PCB upper film button pressure are all within specification limit, and the accurate stroke of controlling, during test, can not damage film key.
Above content is in conjunction with concrete embodiment 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, can also make some simple deduction or replace.
