[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-3 A digital mobile communication comprehensive tester shown in the figure includes a tester body 1. The tester body 1 adopts a digital mobile communication comprehensive tester commonly used in the prior art and suitable for this embodiment. A connection terminal 2 for connecting a tester is provided at the front end of the tester body 1. A dustproof component 3 is installed at the front end of the connection terminal 2. The dustproof component 3 includes:

[0026] A mounting ring 31, the mounting ring 31 is sleeved on the front end of the wiring terminal 2;

[0027] A dust cover 32, the upper end of which is hinged to the upper end of the mounting ring 31, and the dust cover 32 covers the front end port of the terminal block 2;

[0028] A torsion spring is provided at the hinge between the dust cover 32 and the mounting ring 31 .

[0029] Based on the above structure, when the digital mobile communication comprehensive tester is not used, the dust cover 32 automatically closes with the mounting ring 31 under the elastic force of the torsion spring, and covers the front end of the terminal block 2 at the front end of the tester body 1, thereby protecting the opening of the terminal block 2, preventing dust and other small debris from entering the terminal block 2 and affecting the access of subsequent connecting wires, thereby avoiding adverse effects on the test operation and test results (such as the device to be tested cannot be read, data transmission errors, unstable connection, test result errors, etc.); when testing is required, the user only needs to open the dust cover 32, and then insert the device to be tested into the terminal block 2 through the connecting wire to achieve the connection between the device and the tester body 1, and then use the digital mobile communication comprehensive tester to test the device to be tested.

[0030] Preferably, a connecting column 4 is fixed on the surface of the tester body 1, and a plurality of connecting columns 4 are arranged and distributed in a circular array along the circumference of the terminal block 2. One end of the connecting column 4 away from the tester body 1 movably penetrates the mounting ring 31. Through the setting of the connecting column 4, the user only needs to slide the mounting ring 31 along the axis of the connecting column 4 toward the side close to the tester body 1, so that the connecting column 4 can lift the dust cover 32, thereby opening the dust cover 32, making it convenient for the user to insert the device to be tested into the terminal block 2 through the connecting wire, while ensuring the dustproof effect, it is convenient to open the dust cover 32 for subsequent testing operations.

[0031] Preferably, a groove 311 is formed on one side of the mounting ring 31 away from the tester body 1 , and the dust cover 32 is embedded in the groove 311 ;

[0032] A stepped hole 312 is formed on the side wall of the embedding groove 311 close to the tester body 1, and a limit block 41 is integrally formed at the front end of the connecting column 4. The diameter of the limit block 41 is larger than the diameter of the connecting column 4, and the side wall of the limit block 41 close to the tester body 1 abuts against the inner wall of the stepped hole 312 close to the tester body 1;

[0033] The arrangement of the limit block 41 and the stepped hole 312 can prevent the mounting ring 31 from being separated from the connecting column 4 when moving away from the tester body 1 , thereby preventing the front end of the terminal block 2 from being covered and protected.

[0034] Preferably, a compression spring 5 is sleeved on the outer side of the connecting column 4, and the mounting ring 31 is elastically connected to the tester body 1 through the compression spring 5. Through the setting of the compression spring 5, when the connecting wire is not plugged into the terminal 2, the mounting ring 31 automatically moves along the connecting column 4 to the side away from the tester body 1 under the elastic force of the compression spring 5, thereby facilitating the automatic resetting of the mounting ring 31 and the dust cover 32 to form a cover.

[0035] Preferably, a limiting groove 321 is provided on the side wall of the dust cover 32 close to the tester body 1, and the cross section of the limiting groove 321 is a right triangle. The side wall of the dust cover 32 on one side of the limiting block 41 is engaged with the right-angled side wall of the limiting groove 321 in a specific posture. The specific posture refers to the posture of the dust cover 32 when the mounting ring 31 and the dust cover 32 move toward the side of the tester body 1 for a certain distance after the dust cover 32 is opened and the mounting ring 31 and the dust cover 32 move toward the side of the tester body 1 under the elastic force of the compression spring 5.

[0036] Through the setting of the limit groove 321, after the mounting ring 31 and the dust cover 32 move a certain distance toward the side of the tester body 1, the mounting ring 31 and the dust cover 32 move in the direction away from the side of the tester body 1 under the elastic force of the compression spring 5. At this time, the side wall on one side of the limit block 41 is tightly engaged with the right-angle side wall of the limit groove 321, thereby limiting the dust cover 32 and preventing the dust cover 32 from directly overlapping the connection between the terminal 2 and the connecting wire, affecting the stability of the connecting wire, thereby avoiding possible adverse effects on the test process (such as the inability to read the data of the device to be tested and the inability to perform the test operation due to the unstable connection between the connecting wire and the terminal 2).

[0037] Working principle of the utility model: in daily use, when the digital mobile communication comprehensive tester is not used, the dust cover 32 is automatically closed with the mounting ring 31 under the elastic force of the torsion spring, and covers the front end of the wiring terminal 2 at the front end of the tester body 1, thereby protecting the opening of the wiring terminal 2, preventing dust and other small debris from entering the wiring terminal 2 and affecting the access of subsequent connecting wires, thereby avoiding adverse effects on the test operation and the test results. When testing is required, the user only needs to slide the mounting ring 31 along the axis of the connecting column 4 toward the side close to the tester body 1, so that the connecting column 4 can lift the dust cover 32, thereby opening the dust cover 32, and then the device to be tested can be inserted into the wiring terminal 2 through the connecting wire to achieve the connection between the device and the tester body 1, and then the digital mobile communication comprehensive tester can be used to test the device to be tested.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
