Description
The utility model relates to a kind of probe that is applied in the combined tester of testing circuit board, especially refer to a kind of combining of needle body and spring of utilizing, and then it is scalable in the needle plate surface to reach syringe needle, and has automatic guiding needle body bottom, and accurately places the probe of the effect of spring central authorities.
Generally, circuit board must can learn that the circuit on it has or not short circuit through test after finishing the some electronic components of welding.And the method for the testing circuit board that adopts between present industry all is provided with some probes by a tool upper surface, and these some probes cooperate each pin position of circuit board under test bottom surfaces and are provided with.
This case applicant once improved at the probe structure of aforementioned tool, and it is on record to check and approve No. 378756 novel patent of bulletin through application, now explanation as back: see also Fig. 1 and Fig. 2, they are respectively the survey of combined tester probe structure and cut open synoptic diagram, and local enlarged diagram.As shown in the figure, probe 2 is equipped with needle plate 11 surfaces in tool, and each pin of corresponding circuit board under test is drilled with some jacks 111, and this tool 1 upper surface is stacked with clamping plate 12, and these clamping plate 12 are drilled with some and the 111 corresponding perforation 121 of needle plate 11 jacks; And wherein, the perforation 121 of these clamping plate 12 supplies to plug needle body 21, and needle body 21 head ends protrude from clamping plate 12 upper surfaces.
These clamping plate 12 end faces are provided with a top board 13, and the perforation 131 on these top board 13 surfaces is established according to the diameter of corresponding needle body 21 head ends; These clamping plate 12 bottoms then are made as two layers of density board 122, and the perforation of this density board 122 is established according to the Plug Division specification of needle body 21 tail ends, and 122 folders of two layers of density board are established the soft rubber plate 123 that one deck is not holed.
In addition, these needle body 21 head ends are provided with the specification of multiple different-diameter size, and tail end then all is made as the Plug Division 211 of single specification, can plant into 111 li of the set jacks of needle plate 11 in this Plug Division 211; And jack is provided with spring 22 for 111 li, and its end end face connects a conductor jacking block 221, in order to support thimble body 21 bottoms; These spring 22 tail ends directly are connected conducting with lead 3 head ends.
But the structure of above-mentioned probe 2 still has the following part of not improving to the greatest extent to remain to be improved:
1. this spring top must additional processing connects a jacking block that is used for supporting needle body, increases its manufacturing cost relatively and makes degree of difficulty, causes the cost of probe still can't decline to a great extent.
2. this needle body and jack adopt clearance fit; make needle body be able to movable telescopic in jack; but be pressed elastic recovery then at spring; this needle body also can slightly upwards bounce up because of the jacking block on the spring; and not necessarily aim at jacking block central authorities when descending, so, the time regular meeting under automatic situation, cause probe crooked; can't protrude in the jack and syringe needle is placed in, cause the circuit board testing result to lose accuracy.
In view of above-mentioned every shortcoming, the design people exhausts the concentrated research of its intelligence then and overcomes, and then develops the improved probe of a kind of structure, refers to a kind of probe that utilizes the needle body inserted terminal to combine with the spring top especially; Wherein, this spring top is that holding in the palm of one coiling and molding caught the holder of Plug Division to portion.By this design, then need not the additional processing manufacturing support the jacking block of usefulness, can reduce manufacturing cost relatively, and accurately place spring central authorities.
Like this, fundamental purpose of the present utility model is to design a kind of probe, and it is provided with holding in the palm of one coiling and molding and catches the holder of Plug Division and support portion at the spring top, like this, need not the additional processing manufacturing supports the jacking block of usefulness, can reduce manufacturing cost relatively.
Another purpose of the present utility model is to design a kind of probe, and its spring top is provided with holding in the palm of one coiling and molding and catches the holder of Plug Division and support portion, has needle body bottom, automatic guiding location, and accurately places the effect of spring central authorities.
For reaching above-mentioned purpose, the utility model provides 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, reach the spring that an end is equipped with lead, this needle body is arranged in the tool and is positioned at directly over the spring, and its Plug Division then is in contact with one another conducting with the spring top; Wherein, this spring top is that holding in the palm of one coiling and molding caught the holder of Plug Division to portion; By this design, then need not the additional processing manufacturing support the jacking block of usefulness, can reduce manufacturing cost relatively.
In order to make the purpose of this utility model, feature and effect clearer,, the utility model is described in detail below in conjunction with specific embodiment and accompanying drawing.In the accompanying drawing:
Fig. 1 cuts open synoptic diagram for the side of conventional combined tester probe structure.
Fig. 2 is the local enlarged diagram of conventional combined tester probe structure.
Fig. 3 is a probe structure exploded view of the present utility model.
Fig. 4 cuts open synoptic diagram for the probe combinations side that the utility model is applied to combined tester.
Fig. 5 is applied to the local enlarged diagram that the probe combinations side of combined tester is cutd open for the utility model.
See also Fig. 3, it is a probe structure exploded view of the present utility model.As shown in the figure, this probe 4 is by a needle body 41 with Plug Division 411, and the spring 42 that an end is equipped with lead 3 constitutes; Wherein, be provided with the bottom at spring 42 tops and contract in gradually, and diameter is less than Plug Division 411, for portion 421 is supported in the holder of conical socket (or cone-shaped groove), support and contact conducting in 411 bottoms, needle body 41 Plug Divisions in order to holder, and the bottom end face of spring 42 is connected with lead 3.
