Description

Technical Field

[0001] This utility model relates to the field of wireless communication testing technology, and in particular to an OTA test probe mounting structure. Background Technology

[0002] With the rapid development of wireless technologies such as the Internet of Things and satellite communications, OTA testing, as a key means of evaluating the radio frequency performance of wireless devices, places extremely high demands on the installation structure of test probes. Currently, in the setup of OTA testing environments, the traditional practice is to use screws to fix the probe in a specific position. For example, when installing a probe on a vertical ring in some anechoic chambers, holes are drilled in the vertical ring, and screws are used to firmly fix the probe base. This method can ensure the stability of the probe installation and, to a certain extent, guarantee the accuracy of the probe position during testing, preventing it from easily shifting due to slight external interference. However, when setting up an OTA testing environment requires installing a large number of probes, the operation of tightening screws to fix each probe is extremely cumbersome. When it is necessary to adjust the position of the probe or replace the probe, the process of unscrewing and retightening the screws will consume a lot of time, affecting the efficiency of test preparation.

[0003] Based on the above, we propose an OTA test probe mounting structure to solve the aforementioned problems. Utility Model Content

[0004] This invention provides an OTA test probe mounting structure to solve the problem of poor installation efficiency of test probes in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution: An OTA test probe mounting structure includes a mounting bracket, a probe body, and a fixing unit. The mounting bracket has a sliding groove, and the probe body has a mounting part that is slidably connected to the sliding groove. The fixing unit includes multiple fixing clips, each of which includes a wedge block and a slot that matches the wedge block. A moving cavity is formed in the sliding groove, and the wedge block is slidably connected to the inside of the moving cavity. A spring connects the wedge block and the moving cavity. The slot is located at the bottom of the mounting part.

[0006] Preferably, the plurality of fixing clips are asymmetrically distributed along the length of the slide groove.

[0007] Preferably, the wedge block is provided with a pull rod extending to the outside of the moving cavity, and the pull rod is provided with a connecting plate.

[0008] Preferably, the surfaces of the wedge block that contact the mounting portion are all inclined surfaces, used to convert the horizontal thrust of the mounting portion into a vertical compressive force.

[0009] Preferably, the wedge-shaped block has a protrusion on its inclined surface, and the slot has a groove that matches the protrusion.

[0010] Preferably, a wear-resistant layer is provided on the inclined surface of the wedge block.

[0011] The beneficial effects of this utility model are: by sliding the mounting part on the probe body into the groove, as the mounting part gradually enters the groove, the wedge block is engaged in the slot, thereby fixing the position of the mounting part with the fixing clip, reducing the tedious steps of tightening screws for fixing in the traditional process and improving installation efficiency.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] Reference Figures 1-5As shown, an OTA test probe mounting structure includes a mounting bracket 1. During use, the mounting bracket 1 can be flexibly fixed to a suitable position within the mounting bracket using screws or similar means. The probe body 3 can then be mounted on the mounting bracket 1. To facilitate the installation of the probe body 3, a sliding groove 2 is provided on the mounting portion 4. The mounting portion 4 on the probe body 3 is slidably mounted inside the sliding groove 2. To fix the mounting portion 4, a fixing unit is provided within the sliding groove 2. The fixing unit includes multiple fixing clips 5, each including a wedge-shaped block 51 and a slot 52 that matches the wedge-shaped block 51. As the probe body 3 is mounted... As the mounting part 4 gradually enters the slide groove 2, it abuts against the wedge block 51. The wedge block 51 is slidably connected to the moving cavity 6 opened in the slide groove 2, and compresses the spring 7 located between the wedge block 51 and the moving cavity 6, causing it to deform. When the wedge block 51 corresponds to the slot 52 opened at the bottom of the mounting part 4, the spring 7 returns to its original deformation, and the wedge block 51 is locked into the slot 52, thereby fixing the installation position of the mounting part 4. During the operation, the mounting part 4 only needs to be slid into the slide groove 2 to be fixed, which improves the installation efficiency compared to the cumbersome fixing steps of the traditional process using screws.

[0017] Reference Figure 4 As shown, furthermore, multiple fixing clips are asymmetrically distributed along the length of the slide groove 2. The asymmetrical arrangement can make the force on the mounting part 4 in the slide groove 2 more uniform. Compared with the symmetrical arrangement, the asymmetrical method can better adapt to forces and torques in different directions, effectively preventing the mounting part 4 from tilting, shaking or shifting in the slide groove 2, thereby improving the stability and reliability of the entire mechanism.

[0018] When the probe needs to be disassembled for maintenance, the pull rod 8 extending to the outside of the moving cavity 6 on the wedge block 51 is pulled. The pull rod 8 causes the wedge block 51 to descend and compress the spring 7, causing the wedge block 51 to disengage from the slot 52 and enter the interior of the moving cavity 6. At this time, without the wedge block 51 resisting and fixing, the mounting part 4 can slide out from the slide groove 2, realizing the disassembly of the mounting part 4. In order to facilitate the simultaneous release of the fixing of all the fixing clips 5, the pull rods 8 on multiple wedge blocks 51 can be connected to a connecting plate 9. By pulling the connecting plate 9, the fixing of the fixing clips 5 can be released together, making the operation more convenient.

[0019] Reference Figure 3 , Figure 5As shown, furthermore, in order to facilitate the compression of the wedge block 51 when it slides into the groove 2, the surfaces of the wedge block 51 that contact the mounting part 4 are all inclined surfaces. The inclined surface of the mounting part 4 that slides into the groove 2 first will contact the inclined surface on the wedge block 51 first. After the two inclined surfaces contact each other, when the inclined surface of the mounting part 4 contacts the inclined surface of the wedge block 51 first, the horizontal thrust is decomposed into a vertical component through the inclined surface angle, which forces the wedge block 51 to automatically compress the spring 7 and sink down, without the need to manually press the wedge block 51, thus simplifying the installation process.

[0020] Reference Figure 5 As shown, furthermore, after the wedge block 51 is inserted into the slot 52, in order to further improve the fixing effect, a protrusion 10 is provided on the inclined surface of the wedge block 51, and a groove 11 adapted to the protrusion 10 is opened in the slot 52. When the wedge block 51 is inserted into the slot 52, the protrusion 10 is inserted into the groove 11. The protrusion 10 and the groove 11 form a multi-level interlocking structure. When the probe body 3 is subjected to vibration or external impact, the contact point expands from a single inclined surface to multiple discrete protrusions contacting the groove 11, which increases the friction and shear resistance and reduces the risk of mis-locking.

[0021] Reference Figures 1-5 As shown, in order to reduce surface wear of the wedge block 51, a wear-resistant layer is provided on the inclined surface of the wedge block 51. The wear-resistant layer is usually made of a material with high hardness and strong anti-friction properties (such as ceramics, wear-resistant alloys, hardened coatings, etc.), which can effectively resist the frictional loss generated between the inclined surface of the wedge block 51 and the groove 2 during sliding or long-term contact.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
