an antenna test fixture 100, comprising: control box 2, drive arrangement 3, test module 4, drive arrangement 3 fixed mounting in on the control box 2 and can drive test module 4 carries out test operation, test module 4 includes: the driving device 3 is connected to the upper die plate group 41 and can drive the upper die plate group 41 to move towards or away from the lower die plate group 43, the antenna 61 and the terminal 62 are respectively and fixedly placed on the lower die plate group 43, and when the upper die plate group 41 is pressed down, the pressing antenna 61 is in contact with the test substrate 8 and the pressing terminal 62 is in contact with the test PIN (not shown).

Through fixed placing antenna 61 and terminal 62 respectively on lower moulding board group 43, when upper moulding board group 41 pushed down, press antenna 61 and the contact of test base plate 8 and press terminal 62 and test PIN contact, realized will await measuring better fixed of product when the test, promoted the stability and the uniformity of test.

Wherein the drive device 3 comprises: a first cylinder 31, a second cylinder 32, and the upper die plate group 41 includes: a first upper die plate 411, a second upper die plate 412, and the lower die plate group 43 includes: a first lower die plate 431 and a second lower die plate 435, wherein the first upper die plate 411 can move towards or away from the first lower die plate 431 under the driving of the first air cylinder 31, and the second upper die plate 412 can move towards or away from the second lower die plate 435 under the driving of the second air cylinder 32. In this way, the pressing sequence of the first upper die plate 411 and the second upper die plate 412 may be set according to the property of the product to be tested, for example, the first upper die plate 411 may be pressed first, the second upper die plate 412 may be pressed later, the second upper die plate 412 may be pressed first, the first upper die plate 411 may be pressed later, or the first upper die plate 411 and the second upper die plate 412 may be pressed simultaneously.

Referring to fig. 3, a positioning column 45 for pressing a test point of the antenna 61 is further provided, one end of the positioning column 45 is fixedly connected to the pressing block of the second upper pressing template 412, and the other end of the positioning column 45 extends along the pressing direction of the second upper pressing template 435. Illustratively, the positioning column 45 can be clamped into a through hole on the pressing block for fixing, it should be noted that the other end of the positioning column 45 is used for pressing the test point of the antenna 61, and when the test is performed, the second upper pressing template 412 is pressed downwards to move so as to drive the positioning column 45 to move downwards until the positioning column 45 is pressed on the test point of the antenna 61 stably. In this way, it is possible to ensure that the test point of the antenna 61 is sufficiently in contact with the test substrate 8, thereby effectively recognizing the signal to be tested.

As shown in fig. 3 and 4, a terminal limiting groove 4311 is disposed on the first lower die plate 431, and an antenna clamping groove 4351 is disposed on the second lower die plate 435. Thus, before the upper die plate group 41 is pressed down, the terminal 62 may be pre-connected with the test PIN in the terminal limiting groove 4311, and the antenna 61 may be pre-clamped into the antenna clamping groove 4351 for fixing.
