Description
Technical field
The utility model relates to a kind of testing auxiliary device for non-standard USB2.0.
Background technology
At existing electronic equipment, especially USB2.0 mouth computer main board installed all will be tested by a measurement jig, for the USB2.0 mouth of standard, general employing one test platelet (such as EAUSB2.0 high speed test fixture), this test platelet there is standard USB2.0 test connector, standard USB2.0 mouth directly can be inserted test platelet, the other end of test platelet connects oscillograph to be tested, concrete draws stitch D+ in four, USB2.0 mouth, D-, among power supply and grounding leg, the test port tested on platelet is needed to be connected with two measured signal point D+ stitch and D-stitch.But also there are some off-gauge USB2.0 mouths, these off-gauge USB2.0 mouths can not be directly connected on existing test platelet.Existing solution two measured signal point D+ and D-of tested non-standard USB2.0 mouth is added power source and grounding leg is all drawn, be welded on the USB2.0 mouth of standard, then the USB2.0 mouth of standard is connected on existing test platelet (such as EAUSB2.0 high speed test fixture).And the time that welding technology consumes is longer, cause the waste of time and manpower, and need the built-in mouth of welding more, welding technology easily causes the damage of USB port, has higher risk.
Utility model content
The utility model is intended to solve the problems of the technologies described above, a kind of testing auxiliary device for non-standard USB2.0 is provided, comprise the test platelet possessing standard USB2.0 mouth test port, also comprise the first probe and the second probe, one end of described first probe possesses the first probe, for connecing with the first measured point (D-point) phase point of tested non-standard USB2.0 mouth, the other end of described first probe is connected with first test point (D-point) of the standard USB2.0 mouth test port of described test platelet; One end of described second probe possesses the second probe, for connecing with the second measured point (D+ point) phase point of tested non-standard USB2.0 mouth, the other end of described second probe is connected with second test point (D+ point) of the standard USB2.0 mouth test port of described test platelet.
Preferably, described first probe and the connected mode of described first test point are for welding.
Preferably, described second probe and the connected mode of described second test point are for welding.
Preferably, described first probe and described second probe are conductive metal material formation.
Preferably, described testing auxiliary device also possesses housing, and described housing is for holding described test platelet and the first probe and the second probe.
Utilize the testing auxiliary device for non-standard USB2.0 of the present utility model, a little can connect needing the mode of welding tested non-standard USB2.0 mouth to change in existing testing scheme, avoid the risk causing tested non-standard USB2.0 mouth infringement, save test duration and human resources, circuit is simply easy to realize.
Accompanying drawing explanation
Fig. 1 is the structural representation of the testing auxiliary device for non-standard USB2.0 of the present utility model;
Fig. 2 is the circuit diagram of the testing auxiliary device for non-standard USB2.0 of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the testing auxiliary device for non-standard USB2.0 of the present utility model is described in further detail, but not as a limitation of the invention.
As shown in Figure 1, test platelet 2 is accommodated with in housing 1, what test platelet 2 employing in present embodiment is existing EAUSB2.0 high speed test fixture, test platelet 2 is configured with standard USB2.0 mouth test port 3, its four pin are corresponding with four pin of standard USB2.0 mouth respectively, and four pin in the drawings from left to right on direction correspond respectively to power supply, D-point (the first test point), D+ point (the second test point) and ground connection GND.The first probe 4 and the second probe 5 is drawn respectively from D-point (the first test point) and D+ point (the second test point).First probe 4 and the second probe 5 for welding, also can adopt other connected modes with the connected mode of test port 3.One end of first probe 4 and the second probe 5 has the first probe and the second probe respectively, be respectively used to the D-point and the D+ point that a little connect tested non-standard USB2.0 mouth, below, for D-point and the D+ point of tested non-standard USB2.0 mouth, the first measured point and the second measured point is called.
Fig. 2 is the circuit diagram of the testing auxiliary device for non-standard USB2.0 of the present utility model, for the standard USB2.0 mouth test port 3 on test platelet 2, wherein pin pipe D-is the first test point 31, pin pipe D+ is that the second test point 32, VBUS point and GND point are reserved unsettled.Relative equally on tested non-standard USB2.0 mouth 6, pin pipe D-is the first tested pilot 61, and pin pipe D+ is the second tested pilot 62.First of first probe 4 pop one's head in by what weld with the first test point 31 the first tested pilot 61 connect, second of the second probe 5 welded with the second test point 32 is popped one's head in and the point of the second tested pilot 62 connects, thus the connection achieved as shown in Figure 2, namely the first test point 31 is connected to the first tested pilot 61, second test point 32 and is connected to the second tested pilot 62.Thus achieve use existing test platelet non-standard USB2.0 mouth is tested.Avoid in prior art the risk adopting the methods such as welding to damage tested non-standard USB2.0 mouth.
In addition, the first probe 4 also can carry out a survey to the second tested pilot 62, and the second probe 5 also can carry out a survey to the first tested pilot 61 simultaneously, does not affect test result.
Above embodiment is only illustrative embodiments of the present utility model, can not be used for limiting the present invention, and protection scope of the present invention is defined by the claims.Those skilled in the art can in essence of the present invention and protection domain, and make various amendment or equivalent replacement to the present invention, these are revised or be equal to replacement and also should be considered as dropping in protection scope of the present invention.
