[0002] In the prior art, various electronic products, such as GPS devices, computers, and televisions, need to undergo signal testing before leaving the factory. During the test, a test device and the electronic product are connected using a wiring harness, and the signal is detected using a signal testing device. For some electronic products that need to be installed on a vehicle, such as a car GPS, during the test, the connection of the wiring harness is easily loosened due to the vibration of the vehicle during driving, thereby affecting the normal progress of the test.

[0003] After searching, the Chinese patent application number 2023211726539 discloses a GPS signal testing device, including: a main body testing unit, which includes a shielding protection device and a mounting plate installed in the shielding protection cover, the mounting plate is installed with a GPS signal testing host, and a plurality of GPS signal transmitting connectors are provided on one side of the shielding protection device; a connector anti-loosening unit, which includes an adjustment box matching the GPS signal transmitting connector and a bidirectional screw rod rotatably installed on the inner wall of one end of the adjustment box, the other end of the bidirectional screw rod is arranged to penetrate the end wall of the adjustment box outward, the bidirectional screw rod is threadedly connected with a symmetrically positioned threaded sleeve, and the lower side wall of the threaded sleeve is fixedly connected with a corresponding plug rod.

[0004] A GPS signal testing device in the above patent has the following shortcomings: although the bidirectional screw can make the insertion rod press against the signal transmission line connector, since the bidirectional screw is not provided with a corresponding limiter for limiting the position, when the bidirectional screw is subjected to vibration, the bidirectional screw will rotate relative to the adjustment box, causing the insertion rod to loosen relative to the signal transmission line connector, and the stability of the signal transmission line connector cannot be guaranteed.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1

[0028] A signal testing device, such as Figures 1 to 6As shown, it includes a signal tester body 1, and a connector 7 is installed on the signal tester body 1, and a test harness 4 is installed on the connector 7 by insertion, and the test harness 4 and the connector 7 are fixed by a fixing portion, and the fixing portion includes a mounting cover 3 and an elastic clamping member, the mounting cover 3 is fixed to the outer wall of one side of the signal tester body 1 by screws, and two groups of elastic clamping members are respectively slidably connected to the inner walls of the through holes on both sides of the mounting cover 3, and a pad 10 is fixed to the end of the elastic clamping member, and a jack 1 is provided on the pad 10, a positioning plate 14 is fixed to the outer wall of one side of the signal tester body 1 by screws, and a jack 2 is provided on the positioning plate 14, and the jacks 1 and 2 are the same size, and the jacks 1 and 2 are inserted with the same limiting rod 16;

[0029] After the test harness 4 and the connector 7 are fixed by insertion, in order to ensure the stability between the test harness 4 and the connector 7, two sets of elastic clamps can be used to clamp and fix the test harness 4. The elastic clamps have a certain elasticity, so that they can fix test harnesses 4 with different outer diameters. After fixation, the socket 1 on the pad 10 and the socket 2 on the positioning plate 14 are aligned, and the limiting rod 16 is inserted into the socket 2 and the socket 1 in turn. The limiting rod 16 is used to limit the positioning plate 14 and the pad 10, and then indirectly limit the elastic clamp and the test harness 4, ensuring the stability of the elastic clamp in clamping and fixing the test harness 4. In this embodiment, the GPS signal test is taken as an example. The signal tester body 1 is an existing and commonly used device in the testing field and belongs to a mature existing technology. Its principles include:

[0030] Before preparing for GPS testing, you must first wait for the satellite system to transmit signals. During this period, you need to check the working status of the signal tester body 1. After the test environment and equipment conditions are met, the program can be started normally.

[0031] Enter the longitude and latitude so that the tester can receive the corresponding GPS signal, then measure the measuring instrument, collect relevant signals, and measure according to the set parameters;

[0032] From the collected GPS signals, detailed location information can be obtained and various indicators can be analyzed.

[0033] Furthermore, the elastic clamping member includes a spring 11 and a slide rod 13, the slide rod 13 is slidably connected to the inner wall of the through hole opened on the side wall of the mounting cover 3, and the spring 11 is clamped between the pad 10 and the mounting cover 3, and one end of the slide rod 13 is fixed with a clamping block 18 by a screw, and the outer wall of the clamping block 18 is bonded with a rubber pad 12;

[0034] The elastic force of the spring 11 is used to enable the clamping block 18 to fix the end of the test harness 4 by clamping, and the rubber pad 12 protects the test harness 4 to prevent indentations on the surface of the test harness 4 after being clamped.

[0035] Furthermore, a connecting plate 8 is fixed to the outer wall of one side of the signal tester body 1 by screws, and a threaded rod 17 is threadedly connected to the surface of the connecting plate 8, and the bottom of the threaded rod 17 and the top of the limit rod 16 are welded and fixed, and a knob 15 is welded to the top of the threaded rod 17;

[0036] By threading the connection plate 8 and the threaded rod 17 together, the stability of the limiting rod 16 relative to the positioning plate 14 and the backing plate 10 can be ensured.

[0037] Furthermore, the outer walls of both sides of the signal tester body 1 are rotatably connected with handles 2 via a rotating shaft;

[0038] The handle 2 is provided to facilitate carrying the entire device by lifting after the signal test is completed.

[0039] Working principle: When in use, first insert one end of the test harness 4 into the connector 7, and connect the other end of the test harness 4 to the product to be tested. After installation, the elastic force of the spring 11 is used to make the rubber pad 12 on the clamping block 18 fix the test harness 4 by clamping, and the connecting plate 8 and the threaded rod 17 are threadedly connected so that the limit rod 16 is inserted into the second hole on the positioning plate 14 and the first hole on the pad 10 in turn during the downward movement, limiting the position between the positioning plate 14 and the pad 10. During the test, when the signal tester body 1 vibrates, the limit rod 16 limits the position between the positioning plate 14 and the pad 10, so that the elastic clamp can always clamp and fix the test harness 4, thereby ensuring the relative stability between the connector 7 and the test harness 4.

[0040] Example 2

[0041] A signal testing device, in order to facilitate the storage of the test harness 4, such as Figures 1 to 6 As shown, this embodiment makes the following supplements on the basis of embodiment 1: a storage box 6 is fixed to the outer wall of one side of the signal tester body 1 by bolts, and a buckle 9 is integrally formed on the inner wall of the bottom of the storage box 6, and a cover plate 5 is clamped on the top of the storage box 6;

[0042] By providing the buckle 9 , the test harness 4 can be fixed by snapping in after the signal test is completed, and the storage box 6 can be covered by the cover plate 5 to achieve dustproof and moisture-proof functions.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
