Description

Technical Field

[0001] This utility model belongs to the field of cavity filter testing technology, specifically relating to an inverted PIMD striking device fixture. Background Technology

[0002] Cavity filters, as frequency selection devices, are widely used in the field of communication, especially in radio frequency communication. In base stations, filters are used to select communication signals and filter out noise or interference signals outside the communication signal frequency. Cavity filter products need to undergo intermodulation testing. When the product undergoes intermodulation testing, it is necessary to simulate the vibration or mechanical shock generated in actual use. In order to ensure that the performance of the filter remains stable when subjected to external force, it is necessary to conduct an impact test during the test.

[0003] Currently, most testing methods rely on manually striking the filter housing to simulate mechanical vibration. However, the striking force, angle, and frequency cannot be precisely controlled, resulting in poor repeatability of test results, low efficiency, and inability to meet the needs of batch testing. In addition, there are drawbacks such as operational risks and human error. Utility Model Content

[0024] This specific embodiment is an inverted PIMD striking device clamp, the structural diagram of which is shown below. Figures 1-6 As shown, the inverted PIMD striking device fixture includes a fixture body 1, a fixing block 2 for limiting and fixing the product is fixedly installed on the upper end face of the fixture body 1, a first through hole 3 for inserting a cable is provided on the fixture body 1, and at least one boss 4 for conforming to the block surface of the product is fixedly installed on the fixture body 1.

[0025] At least four fixing blocks 2 are provided, and in this embodiment, four are preferred. The four fixing blocks 2 are used to limit and fix the four corners of the product respectively. When in use, the product is upside down on the clamp body 1, and the four corners of the product contact the inner walls of the four fixing blocks 2 respectively. With the cooperation of the four fixing blocks 2, the product can be limited and fixed.

[0026] The fixture body 1 has at least one mounting hole 101 for assembling the fixture body 1 onto the automatic striking device. Under the action of the mounting hole 101, the fixture body 1 can be assembled onto the automatic striking device using screws, and the product can be tested by the automatic striking device. The automatic striking device is existing technology, and its specific structure and principle will not be described here.

[0027] In this embodiment, six bosses 4 are provided. The six bosses 4 are distributed in two columns according to the product. One column has four bosses 4 and the other column has two bosses 4. Each boss 4 is provided with a second through hole 5 that communicates with the first through hole 3.

[0028] In this embodiment, the test cable is directly fixed to the fixture body 1, and then the cavity connector is inserted through the first through hole 3 and the second through hole 5 of the boss 4 of the fixture body 1 to complete the assembly. Then the fixture body 1 is assembled onto the automatic tapping device, which can achieve controllable force, improve efficiency, and ensure product consistency.
