Abstract
The utility model discloses a PCB test fixture guide structure, comprising a first fiber board and a second fiber board which are adjacent to each other. A pinhole is arranged in each fiber board. A testing pin passes through the pinholes. The PCB test fixture guide structure is characterized in that one side of each of the adjacent first and second fiber boards is provided with a guide board, a guide hole is arranged in the guide board arranged on the inner side of the first fiber board corresponding to the pinhole in the second fiber board, the testing pin passes through the first pinhole in the first fiber board, and smoothly inserts into a second guide hole arranged in the second guide board and the second pinhole in the second fiber board through the first guide hole in the first guide board, and the guide boards are fiber boards. According to the utility model, the guide boards are added, the testing pin can easily insert into a fixture, and the probability of inserting into wrong positions is reduced; and at the same time, the swinging of the testing pin is reduced during the fixture lamination test, the accuracy with a PCB test contact is increased, the moving smoothness of the testing pin is increased, and the better testing result is achieved.
Description
Technical field
The utility model relates to the PCB technical field of measurement and test, more particularly, relates to a kind of PCB test fixture guide frame.
Background technology
At present, along with the development of PCB industry, product is also towards high-accuracy, high density future development.
Anchor clamps need to arrange corresponding test point according to the test contact density of PCB in the one side that contacts with test PCB, namely need to insert testing needle, and with the one side of test electronics contact point because can not be identical with PCB test contact size, so testing needle must could link to each other with the Electronic Testing contact with slope.
When testing needle insertion anchor clamps need to have slope, the anchor clamps of common density difficulty when contact pin was little.And during high density, wrong plug pin position easily appears, contact pin does not advance, the problems such as difficult contact pin.
Summary of the invention
In order to overcome when the high density, wrong plug pin position easily appears, and contact pin does not advance, the problems such as difficult contact pin, the utility model provides a kind of PCB test fixture guide frame, and this a kind of PCB test fixture guide frame is so that testing needle easily injects anchor clamps, and has reduced the risk of wrong plug pin position.
The technical scheme that its technical matters that solves the utility model adopts is as described below: a kind of PCB test fixture guide frame, comprise adjacent first, the second fiberboard, be respectively equipped with pin hole on every layer of fiberboard, testing needle passes described pin hole, it is characterized in that: described adjacent first, the second fiberboard one side correspondence is respectively equipped with a guide plate, be located at that the pin hole on corresponding the second fiberboard is provided with a pilot hole on the guide plate of the first fiberboard inboard, the first pin hole that testing needle passes on the first fiberboard inserts the second pilot hole that the second guide plate is provided with and the second pin hole on the second fiberboard smoothly through the first pilot hole guiding that the first guide plate is provided with.
Described guide plate is fiberboard.
According to the utility model of said structure, its beneficial effect is, the utility model has increased guide plate, and testing needle more easily injects anchor clamps, and has reduced the probability of wrong plug pin position; While reduces testing needle and swings when carrying out anchor clamps pressing test, and the accuracy of increase and PCB test contact increases the testing needle motion smooth, has reached better test effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model embodiment one structural representation.
Embodiment
Embodiment one
As shown in Figure 1, a kind of PCB test fixture guide frame, comprise adjacent first, the second fiberboard 1,2, be respectively equipped with pin hole (the first pin hole 101 on every layer of fiberboard, the second pin hole 201), testing needle 3 can pass described pin hole, described adjacent first, the second fiberboard 1,2 inboards are respectively equipped with a guide plate (the first guide plate 4 relatively, the second guide plate 5), be located at that the second pin hole 201 on corresponding the second fiberboard 2 is provided with the first pilot hole 401 on the first guide plate 4 of the first fiberboard 1 inboard, testing needle 3 passes the first pilot hole 401 guiding that the first pin hole 101 on the first fiberboard 1 is provided with through the first guide plate 5 and inserts smoothly the second pilot hole 501 that the second guide plate 4 is provided with and the second pin hole 201 on the second fiberboard 2.
Described guide plate is fiberboard.
This mode can be used in (pin type anchor clamps) on special machine anchor clamps and the universal machine anchor clamps fully.
Although the utility model is described with reference to the above embodiments; it only is for explanation the utility model that but those of ordinary skill in the art can very clearly be recognized above embodiment fully; wherein can make various changes and revise and do not break away from a broad sense the utility model; so be not that conduct is to restriction of the present utility model; as long as in connotation scope of the present utility model, all will fall within the protection domain that the utility model requires variation, the distortion of above-described embodiment.
Claims (2)
1. PCB test fixture guide frame, comprise adjacent first, the second fiberboard, be respectively equipped with pin hole on every layer of fiberboard, testing needle passes described pin hole, it is characterized in that: described adjacent first, the second fiberboard one side correspondence is respectively equipped with a guide plate, be located at that the pin hole on corresponding the second fiberboard is provided with a pilot hole on the guide plate of the first fiberboard inboard, the first pin hole that testing needle passes on the first fiberboard inserts the second pilot hole that the second guide plate is provided with and the second pin hole on the second fiberboard smoothly through the first pilot hole guiding that the first guide plate is provided with.
