Especially for products with various sizes, small batch and large size, if a plurality of the clamps are processed, the types and the cost of the clamps are increased greatly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a test fixture of position, the circulator of different lead wire height around adaptation in not unidimensional size, different lead wires to adopt general such test fixture to realize testing the electrical property index of circulator.
In order to achieve the above object, the utility model provides a following technical scheme: an add-on circulator test fixture includes a test joint and a device housing; the test joint comprises a mounting copper block, a microstrip line circuit board and a connector are arranged on the mounting copper block, and the mounting copper block is arranged to be attached to the outer wall surface of the device shell; the device shell comprises a pin avoiding notch, and a positioning hole perpendicular to the wall surface of the device shell is formed in the outer side surface of the pin avoiding notch; and a positioning piece corresponding to the positioning hole is arranged on the mounting copper block, the mounting copper block is detachably mounted on the device shell through the positioning piece, and the microstrip line is in contact with the pin of the tested device.
In the technical scheme, the positioning hole is preset on the device shell, the test connector is temporarily additionally arranged on the device shell of the tested device, so that the device shell and the test connector jointly form a complete test fixture, the test connector can be quickly and accurately butted with the pin of the tested device by adopting the scheme, and the situation that the specification of the tested device is not matched with that of the fixture is avoided.
Preferably, the locating hole is the screw, the setting element includes mounting bolt and sets up the bolt hole on the installation copper billet, and mounting bolt passes the bolt hole after and installs in the locating hole, can realize firmly fixing of test joint and device through mounting bolt, avoids pin and microstrip line contact failure in the test procedure.
Preferably, two positioning holes are symmetrically formed in the outer side face of each pin avoiding notch, and two positioning pieces are correspondingly arranged on a single installation copper block, so that the stress of the installed test connector can be balanced, and the test connector is prevented from being inclined.
Drawings
The accompanying drawings, which are included to provide a further understanding of the application and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the application and together with the description serve to explain the application and not to limit the application. In the drawings:
fig. 1 is a schematic structural diagram of a test connector according to an embodiment of the present invention.
Fig. 2 is a schematic structural diagram of a pre-assembly state before detection according to an embodiment of the present invention.
Fig. 3 is a schematic plan view of a state to be tested according to an embodiment of the present invention.
In the figure, a copper block 1, a microstrip line circuit board 2, a connector 3, a bolt hole 4, a mounting bolt 5, a device housing 6, a pin avoiding notch 61, a pin 62 and a positioning screw hole 63 are mounted.
Detailed Description
Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.
FIGS. 1-3 illustrate an embodiment of the present invention, an add-on circulator test fixture, comprising three test joints and a device housing 6; the test joint comprises a rectangular installation copper block 1, a microstrip line circuit board 2 is arranged on the top of the installation copper block 1, and a connector 3 is arranged on the outer side face of the installation copper block. The device shell 6 comprises three pin avoiding notches 61, two positioning screw holes 63 are symmetrically arranged on two sides of the outer side face of each pin avoiding notch 61, the positioning screw holes 63 are perpendicular to the wall face of the device shell 6, two bolt holes 4 corresponding to the positioning screw holes 63 are arranged on the installation copper block 1, the whole test joint is installed on the device shell 6 by passing through the bolt holes 4 and installing bolts 5, and the microstrip lines on the microstrip line circuit board 2 are made to contact with pins 62 of a tested device. In the structure, each test joint is fixed on the device shell 6 through two mounting bolts 5, so that the mounting firmness can be ensured, and poor contact between the pin 62 and the microstrip line caused by displacement of the test joint can be prevented.
In this embodiment, the positioning hole is preset on the device housing 6, and the test connector is temporarily additionally arranged on the device housing 6 of the device to be tested, so that the device housing 6 and the test connector jointly form a complete test fixture. And the test connector itself need attach on device casing 6 just can constitute with the test fixture who is surveyed the accurate matching of piece, therefore this kind of anchor clamps itself has fine suitability, only need in the production on the device casing accurate punch can, and punch on the device very easily again, the mode through this kind of difficult transformation has solved current test fixture's various problems completely.
