It can be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0048] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0049] Such as Figures 1 to 10As shown in the figure, the utility model provides a detection device, which includes a first mounting base 100, a fixing component 200, a second mounting base 300 and an abutting component 400. Among them, the fixing component 200 includes a wire harness clamping mechanism 210 and a connector fixing mechanism 220. Both the wire harness clamping mechanism 210 and the connector fixing mechanism 220 are installed on the first mounting base 100. The wire harness clamping mechanism 210 is used to fix the wire harness part 620 of the coaxial cable 600, and the connector fixing mechanism 220 is used to fix the connector part 610 of the coaxial cable 600; the second mounting base 300 is rotatably connected to the first mounting base 100; the abutting component 400 includes an abutting member 410 and a force sensor 420. The abutting member 410 is slidably installed on the second mounting base 300. The abutting member 410 can be coaxially connected to the connector part 610 of the coaxial cable 600 along the axial direction of the coaxial cable 600, or abutted against the connector part 610 of the coaxial cable 600 along the radial direction of the coaxial cable 600. The force sensor 420 is used to obtain the magnitude of the force exerted by the abutting member 410 on the coaxial cable 600.

[0050] Specifically, when the detection device is in use, it can perform tensile strength tests and lateral pressure resistance tests on the coaxial cable 600.

[0051] Exemplarily, as Figure 4 shown, when the detection device performs a tensile strength test, the first mounting base 100 and the second mounting base 300 are clamped at 180°. The wire harness clamping mechanism 210 of the fixing component 200 fixes the wire harness part 620 of the coaxial cable 600, and the connector part 610 of the coaxial cable 600 is then fixedly connected to the abutting member 410. At this time, the axis of the coaxial cable 600 is parallel to the moving direction of the abutting member 410 relative to the second mounting base 300. After the installation is completed, the abutting member 410 is driven to move along the axis of the coaxial cable 600 to the side away from the wire harness clamping mechanism 210. Since the wire harness clamping mechanism 210 is fixedly installed on the first mounting base 100 and remains relatively stationary with the second mounting base 300 during the operation, at this time, the relative movement between the abutting member 410 and the wire harness clamping mechanism 210 forms an axial tensile force on the coaxial cable 600. The force sensor 420 can obtain the magnitude value of this tensile force. As the distance between the abutting member 410 and the wire harness clamping mechanism 210 gradually increases, the tensile force received by the coaxial cable 600 also gradually increases until the connector part 610 of the coaxial cable 600 is loosened from the abutting member 410. By obtaining the magnitude of the force through the force sensor 420, the maximum axial tensile force value that can be borne between the connector part 610 of the coaxial cable 600 and the abutting member 410 can be obtained.

[0052] Exemplarily, as Figure 1As shown, when the detection device performs the anti-lateral pressure test, the first mounting seat 100 and the second mounting seat 300 are clamped at 90°. The joint fixing mechanism 220 of the fixing component 200 fixes the joint part 610 of the coaxial cable 600, and the wire harness part 620 of the coaxial cable 600 is in a suspended state. At this time, the axis of the coaxial cable 600 is perpendicular to the moving direction of the abutting part 410 relative to the second mounting seat 300. After installation, the abutting part 410 is driven to move towards the side where the coaxial cable 600 is located in the direction perpendicular to the axial direction of the coaxial cable 600. The coaxial cable 600 is relatively fixed to the first mounting seat 100 and the second mounting seat 300 through the joint fixing mechanism 220, and the abutting part 410 can abut against the wire harness part 620 of the coaxial cable 600 until the joint part 610 of the coaxial cable 600 is loosened from the joint fixing mechanism 220. By obtaining the magnitude of the force through the force sensor 420, the maximum radial pressure value that can be borne between the joint part 610 of the coaxial cable 600 and the joint fixing mechanism 220 can be obtained.

[0053] In this way, in the present utility model, the first mounting seat 100 and the second mounting seat 300 are rotatably connected. According to the type of test to be performed, the relative position between the two is switched, so that both the tensile test of the coaxial cable 600 and the lateral pressure test can be completed. During this process, only the installation method of the coaxial cable 600 and the detection device needs to be changed, without replacing the parts of the detection device. The operation is simple, the accuracy is high, and the operation efficiency is improved.

[0055] Exemplarily, the first clamping block 211 and the second clamping block 212 are connected by a hinge. The hinge includes a first blade, a second blade and a hinge shaft. The first blade and the second blade are hinged by the hinge shaft. The first blade is fixed to the first clamping block 211, and the second blade is fixed to the second clamping block 212. When using the wire harness clamping mechanism 210 to fix the wire harness part 620 of the coaxial cable 600, the wire harness part 620 of the coaxial cable 600 is placed on the first clamping block 211 and kept parallel to the hinge shaft, and the first clamping block 211 and the second clamping block 212 are buckled.

[0056] Optionally, the first clamping block 211 and the second clamping block 212 are locked by a buckle 213.

[0057] Exemplarily, a buckle is installed on the second clamp 212, and a hook is connected to the first clamp 211 through a connecting piece. After the second clamp 212 is buckled with the first clamp 211, the hook is connected to the buckle, and the connection between the hook and the buckle can be kept stable by tightening the connecting piece.

[0058] Optionally, the first clamping block 211 is installed with a first locking block 2111 , and the second clamping block 212 is installed with a second locking block 2121 .

The first positioning hole, the second positioning hole and the hinge point of the swing arm 221 and the second clamp 212 are not colinear. When the coaxial line 600 is subjected to a tensile force test, the fixing assembly 200 only needs the wiring harness clamping mechanism 210 to participate in the operation. The positioning pin 222 passes through the swing arm 221 and is inserted into the first positioning hole, so that the swing arm 221 avoids the joint portion 610 of the coaxial line 600; when the coaxial line 600 is subjected to a lateral pressure test, the swing arm 221 is rotated, and the positioning pin 222 passes through the swing arm 221 and is inserted into the second positioning hole, and the joint portion 610 of the coaxial line 600 is fixed to the plug connector 223.

The axis of the threaded rod 450 is parallel to the guiding direction of the guide rail 310, and the sliding member 430 can reciprocally move relative to the second mounting base 300 along the axis of the threaded rod 450.
