[0030] like Figures 1 to 3 As shown, an embodiment of the present application provides a docking structure 100, including a main body 110, a PIN needle 120 and a protective cover 130, wherein the PIN needle 120 is connected to the main body 110; the protective cover 130 is reciprocatably connected to the main body 110, so that the protective cover 130 can switch between a docking position and a protective position relative to the main body 110.

[0031] Among them, the protective cover 130 is provided with a protective hole 131 for the PIN needle 120 to pass through, and when the protective cover 130 moves to the protective position, the protective cover 130 and the main body 110 are enclosed to form a protective space 140 connected with the protective hole 131, and the end of the PIN needle 120 close to the protective cover 130 is accommodated in the protective hole 131 and / or the protective space 140; when the protective cover 130 moves to the docking position, the end of the PIN needle 120 close to the protective cover 130 extends out of the protective hole 131.

[0032] It is understandable that the protective cover 130 can reciprocate along the length direction of the PIN pin 120 to expose the end of the PIN pin 120 or accommodate the end of the PIN pin 120 in the protective hole 131 and / or the protective space 140 during the movement.

[0033] By adopting the above-mentioned docking structure, during the test of the device to be tested, the protective cover 130 is moved to the docking position due to pressure, so that the end of the PIN needle 120 extends out of the protective hole 131, and then the PIN needle 120 is docked with the device to be tested; after the test, the protective cover 130 is reset and moved to the protection position, so that the end of the PIN needle 120 is accommodated in the protection hole 131 and / or the protection space 140, thereby preventing the end of the PIN needle 120 from being directly exposed to the air and being contaminated by the outside world, avoiding affecting the signal transmission of the PIN needle 120, and ensuring the accuracy of the test result.

[0034] Specific to Figure 3 In the illustrated embodiment, a portion of the end of the PIN needle 120 is located in the protection hole 131, and another portion is located in the protection space 140. Of course, in other embodiments, the end of the PIN needle 120 may also be completely located in the protection hole 131 or in the protection space 140, as long as the end of the PIN needle 120 can be prevented from being directly exposed to the air.

[0035] In one embodiment, the body 110 includes a mounting portion 111 and a protection portion 112. The PIN pin 120 and the protection portion 112 are both connected to the mounting portion 111, and the protection portion 112 is penetrated by a first through hole 113 for the PIN pin 120 to pass through, and the protection cover 130 is reciprocatably connected to the protection portion 112.

[0036] When the protection cover 130 moves to the protection position, the protection cover 130 and the protection portion 112 enclose a protection space 140 , and the protection space 140 is communicated with the protection hole 131 and the first through hole 113 at the same time.

[0037] It can be confirmed that the PIN pin 120 can pass through the first through hole 113 and the protection hole 131 in sequence, so the first through hole 113 and the protection hole 131 correspond to each other.

[0038] Specific to Figure 1 In the illustrated embodiment, a second through hole 114 is also formed on the mounting portion 111 for the PIN pin 120 to pass through, and the second through hole 114 , the first through hole 113 and the protection hole 131 correspond to each other.

[0039] In addition, only one PIN needle 120 is shown in the figure, but in actual application, there are multiple PIN needles 120, corresponding to the multiple second through holes 114, the multiple first through holes 113 and the multiple protective holes 131, and the multiple PIN needles 120, the multiple second through holes 114, the multiple first through holes 113 and the multiple protective holes 131 correspond one to one.

[0040] In one embodiment, the protective cover 130 has a concave cavity on one side facing the main body 110, and the protective hole 131 is connected to the concave cavity. When the protective cover 130 moves to the docking position, the end of the main body 110 facing the protective cover 130 extends deeply into the concave cavity; when the protective cover 130 moves to the protection position, the end of the main body 110 facing the protective cover 130 and the concave cavity are enclosed to form a protection space 140.

[0041] Please also see Figure 4 In one embodiment, the docking structure further includes a connector 150. The connector 150 is connected to the main body 110, and the protective cover 130 is reciprocatably connected to the connector 150 along the length direction of the PIN needle 120, and can reciprocate between a docking position and a protective position.

[0042] Furthermore, the connector 150 includes a connecting portion 151 and a movable portion 152. The connecting portion 151 is connected to the protective portion 112 of the main body 110, the movable portion 152 is formed at one end of the connecting portion 151 away from the main body 110, and the protective cover 130 is reciprocally connected to the movable portion 152 along the length direction of the PIN needle 120.

[0043] Furthermore, the connecting member 150 further includes a limiting portion 153. The limiting portion 153 is formed at one end of the movable portion 152 away from the connecting portion 151 and is connected to the protective cover 130 to limit the protective cover 130 at the movable portion 152, thereby preventing the protective cover 130 from being separated.

[0044] It should be explained that, in the present embodiment, the movable portion 152 is cylindrical and has a smooth surface. A connecting hole 132 is provided on the protective cover 130. A limiting protrusion 133 is provided on the inner wall of the connecting hole 132. The end of the movable portion 152 close to the protective cover 130 can pass through the limiting protrusion 133 so that the protective cover 130 can move relative to the movable portion 152, and the movable stroke of the protective cover 130 can be adjusted by adjusting the length of the portion of the movable portion 152 that can pass through the limiting protrusion 133; the limiting portion 153 is arranged in the connecting hole 132, and the limiting portion 153 can abut against the limiting protrusion 133, so the limiting portion 153 can limit the protective cover 130 on the movable portion 152.

[0045] Of course, in other embodiments, the connecting member 150 can also be reciprocatably connected to the main body 110 along the length direction of the PIN needle 120, and the protective cover 120 is connected to the connecting member 150, so that the protective cover 130 can be reciprocatably connected to the main body 110 along the length direction of the PIN needle 120.

[0046] In the above case, the connecting portion 151 is fixedly connected to the protective cover 130, and the movable portion 152 is movably connected to the main body 110, specifically the protective portion 112. In addition, a limiting portion 153 may be formed on the movable portion 152 to prevent the connecting member 150 from being separated from the protective portion 112, or a limiting structure may be provided on the protective portion 112, and the limiting structure is used to limit the connecting member 150 or the protective cover 130 to prevent the connecting member 150 or the protective cover 130 from being separated from the protective portion 112.

[0047] In one embodiment, the docking structure further includes a reset member 160, which is disposed between the main body 110 and the protective cover 130 and is used to provide a force to move the protective cover 130 to the protective position. In this way, when the device to be tested is tested, the protective cover 130 first abuts against the device to be tested, and under the action of the device to be tested, overcomes the force of the reset member 160 and moves to the docking position, so that the end of the PIN needle 120 is exposed and docked with the device to be tested.

[0048] Furthermore, the restoring member 160 is sleeved on the movable portion 152 , and two ends of the restoring member 160 are respectively in contact with the protection portion 112 and the protection cover 130 to provide a force for moving the protection cover 130 to the protection position.

[0049] Optionally, the reset member 160 is a spring.

[0050] It can be understood that in order to ensure that the reset member 160 pushes the protective cover 130 to the protective position, multiple connecting members 150 and multiple reset members 160 can be set, and the multiple connecting members 150 are arranged at intervals, and the multiple reset members 160 correspond one by one to the multiple connecting members 150, and are all located between the protective cover 130 and the protective part 112.

[0051] In one embodiment, a first mounting hole 115 is formed on a side of the protection portion 112 facing the protection cover 130, and a second mounting hole 134 corresponding to the first mounting hole 115 is formed on a side of the protection cover 130 facing the protection portion 112. The connecting portion 151 extends into the first mounting hole 115, the movable portion 152 extends into the second mounting hole 134, and both ends of the reset member 160 also extend into the first mounting hole 115 and the second mounting hole 134, respectively.

[0052] It should be noted that the connection hole 132 provided on the protective cover 130 passes through the bottom wall of the second mounting hole 134, and the limiting protrusion 133 is located at one end of the connection hole 132 close to the second mounting hole 134. At the same time, the radial dimension of the connection hole 132 is smaller than that of the second mounting hole 134, the movable portion 152 extends into the second mounting hole 134 and is penetrated by the connection hole 132, and one end of the reset member 160 extends into the second mounting hole 134 and abuts against the bottom wall of the second mounting hole 134.

[0053] In one embodiment, the docking structure further includes a guide post 170. The guide post 170 extends along the length direction of the PIN pin 120, and one end of the guide post 170 is connected to one of the main body 110 and the protective cover 130, and the other of the main body 110 and the protective cover 130 is provided with a guide hole, and the other end of the guide post 170 extends into the guide hole to guide the movement of the protective cover 130.

[0054] Specific to Figure 4 In the illustrated embodiment, a guide hole is provided on the protection portion 112 , one end of the guide post 170 is threadedly connected to the protection cover 130 , and the other end extends into the guide hole, and the guide post 170 cooperates with the guide hole to guide the movement of the protection cover 130 .

[0055] Similarly, in order to ensure that the protective cover 130 moves smoothly along the length direction of the PIN pin 120, a plurality of guide posts 170 may be provided.

[0056] The present application also relates to a testing device, which includes the docking structure in the above embodiment.

[0057] In order to facilitate understanding of the technical solution of this application, Figure 1 and Figure 2 The test process of the docking structure and the test equipment in the above embodiment is described:

[0058] When not testing, the protective cover 130 is kept in the protective position under the action of the reset member 160, and the end of the PIN needle 120 is received in the protective hole 131 and the protective space 140 to prevent the end of the PIN needle 120 from being contaminated by direct exposure to the air. When testing is required, the device to be tested is abutted against the protective cover 130, and the protective cover 130 is pushed to overcome the force of the reset member 160 and move to the docking position, so that the end of the PIN needle 120 extends from the protective hole 131 to dock with the device to be tested, thereby implementing the test of the device to be tested.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
