Abstract
To provide an inspecting jig surely finding the malfunction of blanking in the appearance of a printed circuit board. An inspecting jig that makes an electrical test by a connection condition between contacting probes 2 that is connected or disconnected corresponding to the surface structure of the printed circuit board 1, when a number of contacting probes 2 are supported by insulators 31, 32 and are drawn out to make contact with the surface of the printed circuit board 1. Wherein at least two detecting probes 2a, 2b are provided corresponding to blanking portions in the printed circuit board, and a conductor 5 is provided at a position corresponding to the blanking portions in the direction of drawing out of the detecting probes.
Description
Technical field
The present invention relates to be used for the anchor clamps that the sharp processing of the employed printed circuit board of electronic equipment is checked, especially relate to the anchor clamps of checking the stamping-out working position with electric approach.
Background technology
This printed circuit board is according to mounting object, be that the shape of electronic equipment is carried out sharp processing.Usually, sharp processing is to be undertaken by the stamping-out that uses mould.In this case, sometimes because of the reasons such as wearing and tearing of mould, cause the stamping-out part can not wash out fully and left behind.When the bad phenomenon of this stamping-out is arranged, can produce such problem, the obstacle when promptly becoming part and installing, or can not normally be installed on the electronic equipment, so must remove.
Therefore, carry out visual check in the past, found the stamping-out bad phenomenon.
But,, but then, the situation of over sight (OS) is arranged also sometimes though people's inspection can be found various bad phenomenon.Under the stamping-out condition of poor that rises by mould,, ignore so can not be judged as unusually and easily because of producing bad phenomenon continuously.
Summary of the invention
The present invention considers the problems referred to above and is developed to that purpose is to provide a kind of inspection anchor clamps that can reliably find the stamping-out bad phenomenon of printed circuit board.
In order to achieve the above object, the present invention is a kind of gauging fixture of printed circuit board, wherein, a plurality of contact detection part insulated bodys are supporting, send above-mentioned contact detection part, and make the surperficial butt of itself and printed circuit board, surface structure according to above-mentioned printed circuit board, above-mentioned contact detection part becomes connection status or notconnect state each other, thus, carry out electric checking, it is characterized in that, corresponding with the stamping-out processing part on the above-mentioned printed circuit board, at least be provided with 2 and detect detection parts, the transport direction of above-mentioned detection detection part with corresponding position, above-mentioned stamping-out processing part on, be provided with electric conductor.
The present invention as mentioned above, on the stamping-out processing part of printed circuit board, be provided with 2 contact detection parts at least, and, since be provided with electric conductor in the place ahead of sending of this detection part, therefore, in the stamping-out processing part, the contact detection part should conducting, but if the stamping-out bad phenomenon is arranged, then not conducting, thus can find reliably that stamping-out is bad.Therefore, in the broken string of check circuit figure, short circuit, can check the stamping-out processing part.
Description of drawings
Fig. 1 is the side view that one of expression one embodiment of the invention are checked state.
Fig. 2 is the side view of another inspection state of this embodiment of expression.
Fig. 3 is the side view of the structure of the existing printed circuit board checking device of expression.
Embodiment
Below, with reference to accompanying drawing embodiments of the invention are explained.
Embodiment 1
Fig. 3 is the figure of structure that expression becomes the existing testing fixture on basis of the present invention.This testing fixture is to check whether conducting is used for the terminal of printed circuit board.Make contact detection part 2 from printed circuit board 1 carry out butt up and down, the group of contact detection part 2 up and down is bearing in respectively on the insulcrete 31,32, make it with the portion of terminal butt of printed circuit board 1 and switch on, detect broken string, short circuit.
Again, the Copper Foil of the stamping-out of printed circuit lines 1 part has been removed usually.Therefore, when printed circuit board 1 during not by correct stamping-out, if make contact detection part and this part butt, then not conducting.As prerequisite, if make when stamping-out correctly carries out, make contact detection part and the just conducting of its butt, just available contact detection part judges whether stamping-out is good.
Fig. 1 is the side view of the inspection state of expression one embodiment of the invention.As shown in Figure 1, this embodiment is the example that has utilized the essential structure of terminal testing fixture shown in Figure 3, and the detection part that will be equivalent to contact detection part 2 carries out butt from the both direction up and down of printed circuit board 1, and this point is the same with structure shown in Figure 3.
The embodiment of this Fig. 1 is characterised in that, by paste waiting electric conductor 5 is arranged on the part on the insulcrete 31, corresponding with the stamping-out hole 4 of printed circuit board 1, and setting has and the detection detection part 2a, the 2b that contact detection part 2 same configuration, is connected on this electric conductor 5.
Among Fig. 1, correctly carry out the stamping-out operation of printed circuit board 1 and formed stamping-out hole 4.Therefore, thus detect conducting between detection part 2a, 2b and electric conductor 5 butts detection detection part 2a, the 2b.Like this, and detect the pick-up unit (not shown) that detection part 2a, 2b are connected, just be judged as the stamping-out operation and correctly carry out and formed stamping-out hole 4.
Figure 2 shows that another inspection state of one embodiment of the invention.In this case, printed circuit board 1 fails correctly to carry out stamping-out, result, residual baseplate material 1a and do not form the stamping-out hole.
Therefore, detect detection part 2a, 2b rests on and the state of printed circuit board 1 butt, because no show electric conductor 5, so detect not conducting between detection part 2a, the 2b.Like this, the testing fixture that is connected with detection detection part 2a, 2b just is judged as and does not correctly carry out the stamping-out operation.
Claims (3)
1. the gauging fixture of a printed circuit board, a plurality of contact detection part insulated bodys are supporting, send aforementioned contact detection part and make it and the surperficial butt of printed circuit board, surface structure according to above-mentioned printed circuit board, above-mentioned contact detection part becomes connection status or notconnect state each other, carry out electric checking thus, it is characterized in that
Corresponding with the stamping-out processing part on the above-mentioned printed circuit board, be provided with 2 at least and detect detection part,
On the position corresponding of the transport direction of above-mentioned detection detection part, be provided with electric conductor with above-mentioned stamping-out processing part.
2. the gauging fixture of printed circuit board according to claim 1 is characterized in that, above-mentioned detection detection part is by the structure of sending from the two sides of above-mentioned printed circuit board.
