Abstract
The invention provides a keyboard tin connection test fixture and is applied to a keyboard cable tin connection test. One end of a keyboard cable is provided with a cable connector, and the cable connector is provided with odd-numbered terminal interfaces and even-numbered terminal interfaces. The keyboard tin connection test fixture comprises a plurality of first leads, wherein each first lead is connected with the odd-numbered terminal interfaces, and the other end of each first lead converges at a first contact; a plurality of second leads, wherein each second lead is connected with the even-numbered terminal interfaces, and the other end of each second lead converges at a second contact; a DC source which has one end connected with the first contact and the other end connected with the second contact; and a sounding unit connected in series between the DC source and the first contact or the second contact. According to the invention, the structure is simple, management and control are easy, whether tin connection is generated in the keyboard cable can be tested at ease, and the product quality is guaranteed.
Description
[technical field]
The present invention relates to a kind of tool testing keyboard, be specifically related to a kind of keyboard and connect tin measurement jig.
[background technology]
Nowadays computer is applied in the life of people more and more widely, and therefore the requirement of people to computer quality is also more and more higher.But, when plant produced computor-keyboard, due to the keyboard winding displacement comparatively dense easy company's of causing tin when scolding tin, fraction defective is higher, the tin test procedure also more difficult to govern control of keyboard winding displacement simultaneously, the general practice is by common visual inspection or magnifier detection etc., but this kind of detection method comparatively wastes time and energy, and too much defective products still can be caused to flow out.
In view of this, be necessary to provide a kind of measurement jig in fact, connect tin test difficulty to solve above-mentioned keyboard winding displacement, cause the problem that bad product flows out.
[summary of the invention]
In order to achieve the above object, the invention provides a kind of keyboard and connect tin measurement jig to solve the problem that above-mentioned keyboard winding displacement connects the more difficult to govern control of tin test.
Keyboard provided by the invention connects tin measurement jig, it is applied to keyboard winding displacement and connects in tin test, one end of described keyboard winding displacement has bus bar connector, and described bus bar connector has odd bits terminal interface and even bit terminal interface, and this keyboard connects tin measurement jig and comprises:
Several first wires, its one end is connected with described odd bits terminal interface respectively, and the other end comes together in the first contact;
Several second wires, its one end is connected with described even bit terminal interface respectively, and the other end comes together in the second contact;
Direct supply, its one end is connected to described first contact, and the other end of described direct supply is connected to described second contact;
Phonation unit, it is serially connected with between described direct supply and described first contact or between described second contact.
Especially, one end that described direct supply is connected with described first contact is positive pole.
Especially, described direct supply is 3V.
Especially, described phonation unit is loudspeaker.
Compared to prior art, after keyboard winding displacement of the present invention connects tin measurement jig connection circuit, when in keyboard winding displacement, adjacent two pins or multiple pin connect tin, connect tin measurement jig by this keyboard can form a loop and trigger loudspeaker and sound, tester then can judge that this keyboard winding displacement connects tin, thus facilitates tester greatly.And keyboard winding displacement of the present invention connects the structure of tin measurement jig simply, is easy to management and control, can tests out keyboard winding displacement easily and whether connect tin, ensure that the quality of product.
[accompanying drawing explanation]
Fig. 1 illustrates as keyboard winding displacement of the present invention connects the structural representation of tin measurement jig.
[embodiment]
Refer to Fig. 1 to illustrate, keyboard provided by the invention connects tin measurement jig, it is applied to keyboard winding displacement and connects in tin test, one end of described keyboard winding displacement has bus bar connector 500, described bus bar connector 500 has odd bits terminal interface (1,3,5,7,9) and even bit terminal interface (2,4,6,8,10), and this keyboard connects tin measurement jig and comprises:
Several first wires 100, its one end is connected with described odd bits terminal interface (1,3,5,7,9) respectively, and the other end comes together in the first contact 110;
Several second wires 200, its one end is connected with described even bit terminal interface (2,4,6,8,10) respectively, and the other end comes together in the second contact 210;
Direct supply 300, its one end is connected to described first contact 110, and the other end of described direct supply 300 is connected to described second contact 210;
Phonation unit, it is serially connected with between described direct supply 300 and described first contact 110 or between described second contact 210.
In the present embodiment, one end that described direct supply 300 is connected with described first contact 110 is positive pole.
In the present embodiment, described direct supply 300 is 3V.
In the present embodiment, described phonation unit is loudspeaker 400.
In time testing, described direct supply 300 and described loudspeaker 400 are connected into circuit, if when having any two adjacent pins or multiple pin to connect tin in described keyboard winding displacement, a path can both be formed after connecting into described keyboard and connecting tin measurement jig, now be sounded to remind by triggering loudspeaker 400 keyboard winding displacement described in tester to connect tin; If all scolding tin is good for all pins of described keyboard winding displacement, connect tin measurement jig can not form path by described keyboard winding displacement being connected into described keyboard, loudspeaker 400 now can not be sounded, now then can judge that described keyboard winding displacement pin is that scolding tin is good, thus the operation of subsequent processing can be carried out.
In sum, keyboard winding displacement of the present invention connects tin measurement jig namely whether sounding judges whether this keyboard winding displacement connects tin, now will improve testing efficiency greatly, and facilitate tester by loudspeaker 400 by keyboard winding displacement being connected into test circuit.And keyboard winding displacement of the present invention connects the structure of tin measurement jig simply, is easy to management and control, can tests out keyboard winding displacement easily and whether connect tin, ensure that the quality of product.
It is noted that the invention is not restricted to above-mentioned embodiment, any simple modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, equivalent variations all falls into protection scope of the present invention with modification.
