Specific embodiment

It is described more fully the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although showing this public affairs in attached drawing The exemplary embodiment opened, it being understood, however, that may be realized in various forms the disclosure without the implementation that should be illustrated here Example is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the model of the disclosure It encloses and is fully disclosed to those skilled in the art.

As shown in Figure 1, the utility model embodiment provides a kind of test fixture, which includes:

Tooling ontology 101, driving portion 102, the first compression bar 103 and the second compression bar for being provided with attachment interconnecting piece 1041 104；Wherein, the attachment interconnecting piece 1041 with attachment to be tested for connecting；

The driving portion 102 is connected with the tooling ontology 101；First compression bar 103 divides with second compression bar 104 It is not connected with the driving portion 102；

The tooling ontology 101, for placing mainboard to be tested；

The driving portion 102 when for being tested, drives first compression bar 103 to press under the action of the first external force On the mainboard to be tested, drive later the attachment interconnecting piece 1041 in second compression bar 104 with it is described to be tested Mainboard fastens；After being completed, the attachment interconnecting piece in second compression bar 104 is driven under the action of the second external force 1041 separate with the mainboard to be tested, and first compression bar 103 is driven to leave the mainboard to be tested later.

Embodiment according to figure 1, the test fixture include tooling ontology, driving portion, the first compression bar and are provided with Second compression bar of attachment interconnecting piece.Wherein the attachment interconnecting piece with attachment to be tested for connecting.Tooling ontology for place to Testing host.Need to treat testing host tested when, driving portion drives the first compression bar to be pressed under the first external force On mainboard to be tested, with fixation mainboard to be tested.Continue to drive the attachment interconnecting piece and mainboard to be tested in the second compression bar later It fastens.After treating being completed of testing host, the second external force is applied to driving portion.Driving portion band under the second external force Attachment interconnecting piece in dynamic second compression bar is separated with mainboard to be tested, continues that the first compression bar is driven to leave mainboard to be tested later. By above-mentioned it is found that driving portion can drive in the second compression bar under different external forces in the utility model embodiment Attachment interconnecting piece is fastened or is separated with mainboard to be tested, the personnel that do not need manually fasten or detached accessories interconnecting piece with Mainboard to be tested.Therefore, scheme provided by the embodiment of the utility model may be implemented between attachment interconnecting piece and mainboard to be tested Carry out highly efficient fastening and separation.

In the utility model one embodiment, as shown in Fig. 2, the attachment interconnecting piece 1041 includes accessory connector 1041A and attachment connecting line 1041B；

One end of the attachment connecting line 1041B is connect with the attachment to be tested；The attachment connecting line 1041B's is another One end is connect with the accessory connector 1041A；

Under the drive of the driving portion 102, second compression bar 104 drive the accessory connector 1041A with it is described Connector in mainboard to be tested fastens；

Under the drive of the driving portion 102, second compression bar 104 drive the accessory connector 1041A with it is described Connector separation in mainboard to be tested.

In the present embodiment, as can be seen from Figure 2 one end of attachment connecting line 1041B is connect with attachment to be tested, attached The other end of part connecting line 1041B is connect with accessory connector 1041A.Under the drive of driving portion 102,104 band of the second compression bar Connector 301 in dynamic accessory connector 1041A and mainboard 30 to be tested fastens.In addition, it can be seen that the first compression bar 103 at this time It has been pressed under the drive of driving portion 102 on the surface of mainboard 30 to be tested.

In the present embodiment, from figure 3, it can be seen that under the drive of driving portion 102, the second compression bar 104 drives attachment Connector 1041A is separated with the connector 301 in mainboard 30 to be tested.In addition, it can be seen that accessory connector 1041A with to When connector 301 in testing host 30 separates, the first compression bar 103 is still pressed on mainboard to be tested at this time.First compression bar 103 The effect being pressed on mainboard to be tested be when accessory connector 1041A is separated with the connector 301 in mainboard 30 to be tested, Gu Fixed mainboard 30 to be tested.

In the present embodiment, figure 4, it is seen that the second compression bar 104 drive accessory connector 1041A with it is to be measured After connector 301 in examination mainboard 30 separates.When continuing to the second external force, driving portion 102 drives the first compression bar 103 Leave mainboard 30 to be tested.

In the present embodiment, the concrete type of attachment to be tested can be determined according to business need.Attachment to be tested can be with Including but not limited to screen, camera, player, any one in microphone.

In the present embodiment, the time point that attachment connecting line 1041B is connect with attachment to be tested may include the following two kinds: As soon as, for driving portion 102 apply the first external force before, attachment to be tested is connect with attachment connecting line 1041B.Two, After two compression bars 104 drive the connector in accessory connector 1041A and mainboard 30 to be tested to fasten, by attachment to be tested with it is attached The 1041B connection of part connecting line.

It in the present embodiment, can be in driving portion 102 when needing to treat testing host and attachment to be tested is tested Drive under, the second compression bar 104 drives the connector in accessory connector 1041A and mainboard to be tested to fasten, so as to be tested Mainboard and attachment to be tested establish connection.Testing host and component to be tested can be treated according to business need upon establishment of a connection It is tested.Such as the input test signal into mainboard to be tested and component to be tested.

In the present embodiment, after treating being completed of testing host and attachment to be tested, in the drive of driving portion 102 Under, the second compression bar 104 drives accessory connector 1041A to separate with the connector in mainboard to be tested.So as to test Mainboard to be tested and attachment to be tested after remove the test fixture, with to next group of mainboard to be tested and attachment to be tested into Row test.

According to above-described embodiment, attachment interconnecting piece includes accessory connector and attachment connecting line.It is being tested When, it can quickly drive accessory connector to fasten or separate with the accessory connector in mainboard to be tested by the second compression bar, So that the attachment to be tested connecting with attachment connecting line and mainboard to be tested establish connection.Therefore, attachment to be tested with to Connection can be quickly established between testing host.
