[0076] Another implementation mode:

[0077] As Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown in the figure; the detection portion 50 includes: an operation table 51; a plug - in head 52 connected to the operation table 51; and a linkage portion 53 connected to the first support portion 30 for driving the operation table 51 and the plug - in head 52 to move, and the plug - in head 52 is plugged into or separated from the device to be detected;

[0078] The operation table 51 includes: a support frame connected to the support guide rod 533; and an electric control part arranged on the support frame for controlling the action of the linkage portion 53. Those of ordinary skill in the art, after seeing the disclosed content, can directly and unambiguously know how to set up the operation table 51 without the need to pay creative labor or conduct excessive experiments;

[0079] The plug portion 52 includes: a first outer shell 521, the top of which is connected to the bottom of the operating table 51, and a groove 5211 is formed in the middle of the first outer shell 521; a support block 522, which is slidably connected to the groove 5211 and moves along the groove 5211; an expansion alloy block 523, which is connected to one side of the support block 522; a first elastic pin 524, which is connected to the first outer shell 521 and plugged into the other side of the support block 522 to limit the support block 522; a second spring 525, one end of which is connected to the expansion alloy block 523; a second elastic pin 526, which is connected to the other end of the second spring 525; a plug 527, which is connected to the second elastic pin 526 and is used to plug into the device being tested; and a heat conductor 528, which is connected between the second elastic pin 526 and the expansion alloy block 523.

[0080] The first outer shell 521 has a rectangular parallelepiped structure and has a rectangular parallelepiped groove 5211, forming a reliable support structure that is conducive to the arrangement of other components; the support block 522 can slide along the groove 5211;

[0081] The first elastic latch 524 includes: a second outer shell 5241 connected to the first outer shell 521, and having two first sliding grooves 5241-1 on the outer wall of the second outer shell 5241; a third spring 5242, disposed in the second outer shell 5241; and a first pin 5243, connected to the second outer shell 5241, sliding along the first sliding groove 5241-1, and having one end inserted into the groove 5211 and plugged into the support block 522; the second outer shell 524 1 has a roughly cylindrical structure; the third spring 5242 is a cylindrical spring; the first pin 5243 includes: a circular shaft segment and two sliders symmetrically connected to the circular shaft segment for sliding connection with the first slide groove 5241-1; when in use, the sliders are moved, and the first pin 5243 compresses the third spring 5242 and slides along the first slide groove 5241-1, separating the circular shaft segment from the support block 522, allowing the support block 522 to move freely. After the circular shaft segment and the support block 522 are plugged in, the support block 522 is restrained.

[0082] The second spring 525 is a cylindrical spring;

[0083] The second elastic plug 526 includes: a third housing 5261 connected to the second spring 525; two fourth springs 5262 spaced and connected within the third housing 5261; two second pin shafts 5263 connected to the fourth springs 5262 for plugging into the plug 527 to limit the plug 527; two connecting rods 5264 connected to the second pin shafts 5263 one by one; and two pressing rods 5265 passing through the third housing 5261 and connected to the connecting rods 5264 one by one. The third housing 5261 is formed by welding plates and has a circular structure with a circular groove in the middle, which is beneficial for accommodating the plug 527. The fourth spring 5262 is a cylindrical spring. The second pin shaft 5263 is a section of a round shaft, with one end welded to the fourth spring 5262 and the other end plugged into the arc-shaped groove on the plug 527. The middle part of the connecting rod 5264 is movably connected to the third housing 5261 through a pin shaft, and the pin shaft forms the rotation center line of the connecting rod 5264.

[0084] When the plug 527 needs to be replaced, press the pressing rod 5265. The pressing rod 5265 drives the connecting rod 5264 to rotate at an angle with the pin shaft as the rotation center, thereby driving the second pin shaft 5263 to compress the fourth spring 5262. The second pin shaft 5263 disengages from the arc-shaped groove on the plug 527, and the plug 527 can be removed.

[0085] The plug 527 is a common structure in the prior art and is matched and plugged with the connection plug on the device to be detected.

[0086] The expansion alloy block 523 or the heat conducting member 528 adopts common materials in the prior art.

[0087] It further includes: a cooling part 529 arranged at the groove 5211 for blowing air to the connection part between the plug 527 and the device to be detected. The cooling part 529 includes: an airbag 5291 connected to the groove 5211; an air injection pipe 5292 communicated with the airbag 5291; and a pressing plate 5293 connected to the heat conducting member 528. The airbag 5291 is a common structure in the prior art. The air injection pipe 5292 adopts a nozzle in the prior art. The pressing plate 5293 presses down the airbag 5291, and the gas is ejected from the air injection pipe 5292, reducing the temperature at the connection part between the plug 527 and the device to be detected, and having better safety.

[0088] The linkage part 53 includes: two second threaded rods 531, which are movably connected to the first support part 30 one by one and pass through the second space 31; two first driving motors 532, which are connected to the first support part 30 one by one to drive the rotation of the second threaded rod 531; and two support guide rods 533, which are threadedly connected to the second threaded rod 531 one by one, and the support guide rods 533 pass through the first support part 30 and are connected to the operation table 51. The second threaded rod 531 is connected to the first support part 30 through a flange bearing seat, so that the second threaded rod 531 can be reliably supported and can also rotate freely. The length dimension of the threaded section on the second threaded rod 531 is approximately 1 / 2 of the length dimension of the second threaded rod 531 to prevent the support guide rod 533 from shifting excessively. The first driving motor 532 is a common structure in the prior art. The support guide rod 533 is threadedly connected to the second threaded rod 531.

[0089] During detection, the device to be detected is limited between the elastic clamping part 40 and the blocking part 20. The operation table 51 presses a button, the first driving motor 532 operates, drives the rotation of the second threaded rod 531, the support guide rod 533 moves along the second threaded rod 531, the plug 527 slowly approaches the device to be detected, and the plug 527 is inserted into the device to be detected. When the temperature at the insertion part exceeds 45°C and is still rising, the heat is transferred from the heat conducting part 528 to the expansion alloy block 523. The expansion alloy block 523 expands, the support block 522 moves towards the first elastic pin 524, compresses the first elastic pin 524, and the second spring 525, the second elastic pin 526, the plug 527 and the heat conducting part 528 move along with it. The plug 527 gradually disengages from the device to be detected. The detection safety is better, and through detection, an obvious detection result can be obtained. The connection plug at the device to be detected generates a high temperature (temperature greater than 45°C) and needs to be replaced again.

[0090] When the heat conducting part 528 moves along with it, it can drive the extrusion plate 5293 to press down the airbag 5291, and the gas is ejected from the spray pipe 5292, reducing the temperature at the connection part between the plug 527 and the device to be detected, and the safety is better.

[0091] The first elastic pin 524 is provided to limit the support block 522. The reason is that the positions of the connection plugs on the device to be detected are not unified. By changing the position of the first elastic pin 524 or providing multiple slots on the support block 522, after the slots at different positions are inserted into the first elastic pin 524, the support block 522 is limited at different positions, realizing the change of the position of the plug 527, and the operation flexibility is better.

[0092] The working principle is as follows: The elastic clamping part 40 clamps the device to be detected; while clamping the device to be detected, the elastic clamping part 40 drives the blocking part 20 to move. A part of the blocking part 20 penetrates out of the first space 11 and protrudes outside the cabinet body part 10, blocking one side of the device to be detected between the first support parts 30. The device to be detected is limited between the elastic clamping part 40 and the blocking part 20; the detection part 50 moves, and a part of it is inserted into the device to be detected to detect the device to be detected.

[0093] In the description, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc. indicating the orientation or position relationship are based on the position relationship described in the drawings, and are only for the convenience of description or simplification of the description, rather than indicating a specific orientation that must be had; the operation process described in the embodiment is not an absolute usage step, and corresponding adjustments can be made during actual use.

[0094] Unless otherwise defined, the technical terms or scientific terms used herein should have the ordinary meaning understood by those of ordinary skill in the art; the "first", "second" and similar terms used in the specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, the terms such as "a" or "one" do not determine the quantity limit, but indicate the existence of at least one, and need to be determined according to the content of the embodiment.

[0095] The above is only a preferred specific implementation manner, but the protection scope is not limited thereto. Any equivalent replacement or change made according to the technical solution and its inventive concept within the technical scope disclosed by those skilled in the art should be covered by the protection scope.
