Description

Technical Field

[0001] This utility model relates to the field of interface testing, and in particular to a test box interface protection structure. Background Technology

[0002] With the rapid development of electronic devices, high-speed data transmission interfaces such as Type-C are increasingly widely used in the testing field. As a key tool for testing electronic devices, test boxes typically contain test boards and integrate various test interfaces.

[0003] However, test interfaces are susceptible to mechanical stress during frequent insertion and removal. Traditional test boxes expose the interface only through through-holes in the housing, lacking an effective internal fixing and protection structure. This makes the solder joints between the test interface and the test board prone to breakage or poor soldering due to external forces, seriously affecting test stability and equipment lifespan.

[0004] Secondly, the peripheral interface lacks a reliable positioning and fixing mechanism. When the male connector of the peripheral under test is inserted into the test box, the peripheral itself is often suspended in the air, relying solely on the mechanical strength of the interface to withstand external forces, which can easily lead to interface deformation or poor contact. This problem is particularly prominent in harsh environments such as vibration testing. Utility Model Content

[0005] The purpose of this utility model is to provide a test box interface protection structure that can effectively disperse the mechanical stress on the test interface and adapt to the fixing requirements of peripherals, thereby improving test reliability and extending the service life of test equipment.

[0006] The technical solution of this utility model is:

[0007] A test box interface protection structure, wherein the test box includes a shell and an internal test plate, the test plate has a test interface, and the test box shell has through holes corresponding to the test interface positions, characterized in that the interface protection structure includes a pressure block pressing on the test interface, the pressure block has a pressure groove adapted to the test interface in the middle of its lower side, and the two ends of the pressure block are fixed to the test plate.

[0008] Preferably, the pressure block has screw holes at both ends and is fixed to the test plate by screws.

[0009] Preferably, the outer side of the test box housing is also provided with an external interface protection component corresponding to the test interface position.

[0010] Preferably, the peripheral interface protection component includes a support block and a pressure plate. The support block is fixed to the outside of the housing. The upper middle part of the support block is provided with a through groove corresponding to the position of the test interface. The peripheral interface to be tested passes through the through groove and the housing through hole to connect to the test interface. The two ends of the pressure plate are detachably fixed to the two ends of the support block, respectively, so as to fix the back shell of the peripheral interface to be tested in the through groove of the support block.

[0011] Preferably, the two ends of the pressure plate are fixed to the two ends of the support block by screws and screw holes.

[0012] Preferably, the test interface is a Type-C female port.

[0013] The advantages of this utility model are:

[0014] 1. The test box interface protection structure of this utility model, by setting pressure blocks on the test plate, using pressure grooves to adapt to the test interface, and fixing both ends with screws, can effectively disperse the stress during the insertion and removal process, prevent the test interface solder joints from breaking or becoming poorly soldered due to external forces, and improve the durability and test stability of the interface.

[0015] 2. This utility model can stably fix the back shell of the peripheral device under test by adding a peripheral interface protection component on the outside of the shell, and avoid the peripheral interface from becoming loose or having poor contact due to vibration or external force. It is especially suitable for harsh environments such as vibration testing. Attached Figure Description

[0021] like Figure 1 , 2 As shown, the test box in this embodiment includes a shell (including an upper shell 1 and a lower shell 2) and a test board 3 inside it. The test board 3 is equipped with a test interface 4. In this embodiment, the test interface 4 is a Type-C female port. The lower shell 2 is provided with a through hole 21 corresponding to the position of the test interface 4.

[0022] The test box interface protection structure of this utility model includes a pressure block 5 located inside the housing and a peripheral interface protection component 6 located outside the housing. The pressure block 5 is used to press the Type-C female connector, and the peripheral interface protection component 6 is used to clamp the rear shell 7 of the peripheral Type-C male connector.

[0023] like Figure 3As shown, the pressure block 5 has a pressure groove 51 adapted to the Type-C female connector in the middle of its lower side, and screw holes at both ends of the pressure block, which is fixed to the test board 3 by screws. By using the pressure groove 51 to press the Type-C female connector, the stress during the insertion and removal process can be effectively distributed, preventing the test interface solder joints from breaking or becoming poorly soldered due to external force, thereby improving the durability and test stability of the interface.

[0024] like Figure 2 and 4 As shown, the peripheral interface protection component 6 includes a support block 61 and a pressure plate 62. The support block 61 is fixed to the outside of the housing. A through slot corresponding to the Type-C female port is provided in the middle of the upper side of the support block 61. The peripheral interface under test passes through the through slot and the through hole 21 of the housing to connect to the Type-C female port. The two ends of the pressure plate 62 are fastened to the two ends of the support block 61 by hand-tightening screws 63, thus fixing the rear shell 7 of the peripheral interface under test in the through slot of the support block 61. This prevents the peripheral interface from loosening or making poor contact due to vibration or external force, and is especially suitable for harsh environments such as vibration testing.
