Abstract
Description
Technical Field
[0001] The utility model relates to the technology of fixture structure, in particular to a multi-functional radio frequency module general test fixture. Background Art
[0002] After the production of the radio frequency module is completed, environmental tests and vibration tests need to be carried out to detect whether various performances of the radio frequency module meet the design indicators through the environmental tests and vibration tests.
[0003] When testing the performances of the radio frequency module, the radio frequency module needs to be positioned by a test fixture. However, the sizes of customized radio frequency modules are different from those of conventional radio frequency modules, and customized test fixtures matching the customized radio frequency modules need to be manufactured separately, resulting in a large variety of customized test fixtures to be produced, high production costs, and inconvenient management. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that there are a large variety of customized test fixtures for the production of customized radio frequency modules and high production costs. The purpose is to provide a multi-functional radio frequency module general test fixture, which replaces the replacement of customized test fixtures by replacing the product carrier plate with low production cost, thereby reducing the production cost.
[0005] The utility model is realized by the following technical solutions:
[0006] A multi-functional radio frequency module general test fixture includes a product carrier plate and a main body support. A product installation groove is arranged on the product carrier plate, and a boss is arranged in the installation groove. The boss is used for positioning the radio frequency module. At least two sliding grooves are arranged on the main body support, and the product carrier plate is detachably connected to the sliding grooves.
[0007] For the utility model adopting the above scheme, by setting the product carrier plate to position the radio frequency module and detachably connecting the product carrier plate to the sliding grooves on the main body support, when testing different customized radio frequency modules, by replacing the product carrier plate (the product carrier plate has a simple structure and low production cost), it is realized that various customized radio frequency modules can be positioned on the same main body support for various tests, instead of replacing the whole customized test fixture to meet the positioning of different customized radio frequency modules, reducing the number of customized fixtures produced and reducing the production cost.
[0008] In some embodiments, at least two bosses are arranged, and the bosses are used for cooperating with the bottom grooves of the radio frequency module. By setting the bosses to cooperate with the bottom grooves of the radio frequency module, the radio frequency module is prevented from moving in the installation groove, affecting the accuracy of test data.
[0009] In some embodiments, the main body bracket includes two frames and several mounting plates. The main body bracket is in an overall rectangular frame shape. The frames form the struts of the main body bracket, and the mounting plates form the crossbeams of the main body bracket. Both ends of the mounting plate are respectively connected to the two frames. A long strip-shaped through hole is provided in the middle of the mounting plate, and the long strip-shaped through hole extends along the length direction of the mounting plate. The long strip-shaped through hole forms the slideway, and the two slideways on the same horizontal plane are respectively detachably connected to both sides of the product carrier plate. This facilitates the horizontal installation of the product carrier plate on the main body bracket.
[0010] In some embodiments, the main body bracket further includes a connector mounting plate and several fixed connectors. The fixed connectors are used for electrically connecting to the test equipment. The connector mounting plate is connected to one of the frames and is located on the side of the frame away from the mounting plate. Several fixed connectors are fixedly connected to the corresponding positions on the connector mounting plate. Setting the connector mounting plate on the outer side of the frame facilitates the positioning and support of the fixed connectors through the connector mounting plate.
[0011] In some embodiments, the product carrier plate includes several movable plugs. The movable plugs are connected to one end of the product carrier plate, and the movable plugs can be plugged into the corresponding fixed connectors. By providing movable connectors on the product carrier plate to plug into the fixed connectors, rapid plugging is achieved, and the efficiency of replacing the product carrier plate is improved.
[0012] In some embodiments, a flexible cable is connected to the movable plug. The flexible cable is used for electrically connecting the radio frequency module to the movable plug. In this way, by setting the flexible cable to be connected to the movable connector, it is convenient to utilize the flexible characteristic of the flexible cable to connect to the radio frequency module, prevent breakage at the connection during vibration, and also realize the electrical connection between the product and the test equipment, and obtain data of the product during environmental testing and vibration testing through the test equipment.
[0013] In some embodiments, a plug positioning plate is connected to one end of the product carrier plate, and the movable plug is connected to the plug positioning plate. Setting the plug positioning plate to position and support the movable plug facilitates the rapid plugging of the movable plug and the fixed plug when the product carrier plate is installed on the main body bracket.
[0014] In some embodiments, vibration equipment connection structures are provided on both sides of the product carrier plate. The vibration equipment connection structures are used for connecting the product carrier plate to the vibration equipment. When the radio frequency module is subjected to vibration testing, the product carrier plate is not connected to the main body bracket and is in a state of being connected to the vibration equipment. During environmental testing, the product carrier plate is detachably connected to the main body bracket. During vibration experiments, the product carrier plate is connected to the vibration equipment through the vibration equipment connection structures, so that the product carrier plate can be positioned in two test states, improving the versatility of the product carrier plate.
[0015] In some embodiments, the vibration device connection structure is a vibration device connection hole, and at least two vibration device connection holes are respectively provided on both sides of the product carrier plate. The provision of the vibration device connection holes facilitates the connection of the product carrier plate to the vibration device by passing bolts or pins through the vibration device connection holes and then connecting to the vibration device, and also facilitates the disassembly and installation of the product carrier plate.
[0016] In some embodiments, several avoidance holes are provided on the product carrier plate, and the avoidance holes are used for the wire harness connected to the radio frequency module to pass through. The provision of the avoidance holes enables the wire harness to be smoothly connected to the radio frequency module.
[0017] Compared with the prior art, the present utility model has the following advantages and beneficial effects:
[0018] 1. By replacing the product carrier plate (the product carrier plate has a simple structure and low production cost), positioning of various customized radio frequency modules can be achieved on the same main body bracket for various tests, instead of replacing the entire customized test fixture to meet the positioning of different customized radio frequency modules, reducing the number of production customized fixtures and lowering the production cost.
[0019] 2. A boss is provided to cooperate with the bottom groove of the radio frequency module to prevent the radio frequency module from moving in the installation groove and affecting the accuracy of test data.
[0020] 3. By providing a movable joint and a fixed joint on the product carrier plate to be inserted into each other, rapid insertion is achieved, improving the efficiency of replacing the product carrier plate. BRIEF DESCRIPTION OF THE DRAWINGS
