Description
Technical field
The present invention relates to USB interface technical field of measurement and test, test male in particular to a kind of USB.
Background technology
USB (Universal Serial Bus, serial data bus) male is a kind of common connector, of many uses.User is in the USB function course using mobile phone, firmly comparatively large owing to frequently plugging in a direction, may occur the situation of USB disabler.Therefore, withstand voltage properties test can be done to the interface of USB in the design phase of mobile phone.
Fig. 1 is the front view that in prior art, USB tests male.As shown in Figure 1, during test, USB being tested male 10 inserts in mobile phone USB female seat, then by the 11 couples of USB in Handheld Division test male 10 apply respectively to be right against mobile phone USB female seat upwards, downwards, left, to the right and the thrust of the thrust different directions in inside 5 directions, because Handheld Division 11 is plastic material, when test man applies enough large thrust, Handheld Division 11 may power equidirectional on occur distortion, operate portions 12 can move along with distortion simultaneously backward, the moment of build-up of pressure becomes large, thus affects the accuracy of experimental result.
In sum, be necessary to provide a kind of USB to test male, to solve the problem.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of USB and tests male, to improve the accuracy of the withstand voltage properties test result of USB interface.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of USB to test male, for the withstand voltage properties of testing mobile phone USB female seat, this USB tests male and comprises rectangular metal shell, rectangular metal shell is provided with integrated operate portions and extension, operate portions and mobile phone USB female seat are equipped with, when testing, one end of operate portions is inserted in mobile phone USB female seat and is placed in mobile phone USB female seat to make operate portions, extension extends from the other end of operate portions, when operate portions is placed in mobile phone USB female seat, what extension reception was applied thereto is right against mobile phone USB female seat upwards, downwards, left, to the right and the thrust of inward direction.
Wherein, operate portions is provided with cavity, when operate portions is placed in mobile phone USB female seat, and the USB wiring board in cavities contain mobile phone USB female seat.
Wherein, the length of metal shell is 30 ± 0.2mm.
The invention has the beneficial effects as follows: the present invention tests the metal shell of male by extending USB, the USB caused because of test man's applied thrust when avoiding test tests male distortion, improves the accuracy of test result.
Further, USB tests the prolongation of male metal shell, the selectivity of test man when testing for applied thrust position is increased greatly, thus improves the precision of test result.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Fig. 2 is the front view that USB of the present invention tests male one embodiment, and Fig. 3 is the lateral plan that USB of the present invention tests male one embodiment.Shown in composition graphs 2 and Fig. 3, USB tests the withstand voltage properties of male 100 for testing mobile phone USB female seat, and it comprises metal shell 110.
Wherein, this metal shell 110 comprises operate portions 120 and extension 130, and operate portions 120 and mobile phone USB female seat are equipped with, and extension 130 is extended from the other end of operate portions 120.
In the present embodiment, operate portions 120 and extension 130 one-body molded, namely between operate portions 120 and extension 130 without any the interface of outside and solder joint.In other embodiments, for convenience of assembling, operate portions 120 and extension 130 can be and combine formation with connecting method.
In the present embodiment, the one side of the operate portions 120 of preferable alloy shell 110 is also provided with the shell fragment 140 of outwardly convex, makes USB test male 100 and increases with the frictional resistance of mobile phone USB female seat, enhance the fastness of combination between the two.
Fig. 4 is the three-dimensional view that USB of the present invention tests male 100.As shown in Figure 4, operate portions 120 is also provided with cavity 121, and when operate portions 120 is placed in mobile phone USB female seat, cavity 121 is for holding the USB wiring board in mobile phone USB female seat.
Wherein, for ease of more firmly holding the USB wiring board in mobile phone USB female seat and simulating the structure of USB male joint more really, USB wiring board support (not shown) also can be set in cavity 121.This USB wiring board support and operate portions 120 realize face and contact and directly fit in cavity 121, and match with the USB wiring board in mobile phone USB female seat when testing.
The principle of work that USB of the present invention tests male 100 is: when testing the withstand voltage properties of mobile phone USB female seat, one end of operate portions 120 is inserted in mobile phone USB female seat by test man, is placed in mobile phone USB female seat to make operate portions 120.Then by extension 130 apply to be right against mobile phone USB female seat upwards, downwards, left, to the right and the thrust (as shown in Figure 5) in inside 5 directions, continuous, multidirectional exerting pressure is carried out with the operate portions 120 pairs of mobile phone USB female seats making USB test male 100, because extension 130 is scleroid metal material, can not be out of shape because of the effect of thrust, therefore can significantly improve the accuracy of the test result of the withstand voltage properties of mobile phone USB female seat.
It should be noted that, extension 130 can also arrange anti-slip part, so that play anti-skidding effect when test man carries out manual test.
In addition, the plant equipment of similar machine human arm also can be used to replace test man's applied thrust, and the present invention is not construed as limiting this.
In the present embodiment, the length inserting mobile phone USB female seat for real USB male joint is generally 5.88mm, the length of preferable alloy shell 110 is 30 ± 0.2mm, the length of operate portions 120 is more than or equal to 5.88mm, the length of extension 130 according to the design requirement testing male 100 to USB, suitably can adjust.In other embodiments, according to the needs of test, the length of metal shell 110 also can be other numerical value.It should be noted that, concrete structure and the size of cavity 121 and operate portions 120 can refer to prior art, repeat no more herein.
In sum, the present invention tests the metal shell of male by extending USB, and the USB caused because of test man's applied thrust when avoiding test tests male distortion, improves the accuracy of test result.
Further, USB tests the prolongation of male metal shell, the selectivity of test man when testing for applied thrust position is increased greatly, thus improves the precision of test result.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
