Abstract
Description
Technical Field
[0001] This disclosure relates to the field of testing equipment technology, and in particular to a testing device for the plug-in / plug-out lifespan of a network interface. Background Technology
[0002] With the development of information technology, connections between network devices are becoming more frequent, and the number of times network interfaces are plugged and unplugged is also increasing. Computers, in particular, have become an indispensable tool in people's daily lives and work. As a key component of wired network connections for laptops, the stability and durability of the RJ45 network interface directly affect the user experience.
[0003] Traditional RJ45 network interfaces may experience contact problems after repeated plugging and unplugging. For network equipment manufacturers, ensuring the durability and reliability of their products is crucial. Currently, durability and reliability testing of RJ45 network interfaces typically uses manual plug-and-unplug tests. Technicians manually insert the RJ45 connector into the RJ45 network interface, then hold the spring contacts on the connector and pull it out, repeating this a certain number of times. The disadvantages of this testing method are: low efficiency (requiring manual operation, unable to simulate high-frequency plugging and unplugging, making it difficult to accurately assess performance under long-term use); susceptibility to human error (human testing usually involves one or a few people repeating the test a certain number of times, failing to simulate the usage of a large number of users); and unsuitability for prolonged manual operation in extreme environments (high / low temperatures, toxic gases, etc.).
[0004] Therefore, it is necessary to design an effective simulation testing device to evaluate the durability and stability of RJ45 network interfaces. Utility Model Content

[0065] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0066] Firstly, such as Figure 1-5 As shown, this application provides a network interface plug-in / plug-out lifespan testing device 1. The network interface 31 is used for plugging and unplugging into a crystal head 2. The crystal head 2 includes a crystal head body 21 and a spring contact 22. The testing device 1 includes:
[0067] The first drive mechanism 11 has a first output end 111 capable of reciprocating linear motion;
[0068] The crystal head retainer 12 is configured to exert clamping forces on the crystal head body 21 in a first direction, a second direction, and a third direction to limit the displacement of the crystal head body 21 in the first direction, the second direction, and the third direction.
[0069] The elastic reset component 13 is movably connected to the crystal head mounting base 12. The elastic reset component 13 is configured to generate an elastic force on the crystal head mounting base 12 to push the crystal head 2 toward the network interface 31 or pull the crystal head away from the network interface 31.
[0070] An angle adjustment component 14 is connected to the first output terminal 111 and the elastic reset component 13. The angle adjustment component 14 is configured to rotate around the central axis of the first output terminal 111 to adjust the angle of the elastic reset component 13 and the crystal head fixing bracket 12, thereby adjusting the angle when the crystal head 2 is inserted into the network interface 31.
[0071] The bent rod 15 is connected to the angle adjustment assembly 14. The bent rod 15 is configured to exert a clamping force on the first position 221 of the spring piece 22 along a third direction and to exert no force on the second position 222 of the spring piece 22, wherein the first position 221 is higher than the second position 222.
[0072] For example, the first direction is Figure 4 The X direction is shown, the second direction is the Y direction, and the third direction is the Z direction.
[0073] For example, the first drive mechanism 11 is a telescopic mechanism. For example, the bent rod 15 has an upwardly convex arc-shaped structure, causing the bent rod 15 to bend at a certain angle, so that the free end of the bent rod 15 forms a third-direction clamping force on the first position 222 of the spring clip 22 of the crystal head, thereby allowing the crystal head to be smoothly inserted into the network interface 31 from the initial stage. Figure 8-9 As shown.
[0074] In this application, the network interface 31 is a key component of the limited network connection of the electronic device, and the network interface 31 includes, but is not limited to, an RJ45 interface. The crystal head 2 is a connector, which includes, but is not limited to, an RJ45 connector.
[0075] Currently, the insertion and removal lifespan of the network interface 31 is tested manually, resulting in large testing errors and low efficiency. Therefore, this application, by setting up a first drive mechanism 11, a crystal head fixing seat 12, an elastic reset component 13, an angle adjustment component 14, and a bending rod 15, enables the testing device 1 to quickly and efficiently perform automatic insertion and removal operations on the network interface. By setting parameters such as the frequency, number of tests, and force for each round of testing, it simulates the differences in user habits among multiple users and ensures the consistency and standardization of each round of insertion and removal actions, thereby making the test results more accurate. Furthermore, using the testing device 1 of this application saves manpower: no continuous manual supervision and operation are required, reducing labor costs. Environmental adaptability: For some special working environments, such as high temperature or toxic gas environments, automated testing is safer and more reliable. Scalability: It is easy to integrate into existing production lines or testing environments, supporting more test items. In addition, compared to other methods that use robotic arms or other large automated devices to simulate the insertion and removal actions of crystal heads, this structure is simpler and has a lower cost.
[0076] Furthermore, the speed and force with which end users plug and unplug network interfaces 31 vary. Generally, users plug and unplug network cables at speeds of approximately 1-3 centimeters per second, with a force between 0.5-2 Newtons. The testing device in this application can be set to multiple different speed and force levels within this range, and these levels can be varied randomly or in a preset pattern during testing to more realistically simulate actual user operating habits. This allows for the detection of wear on the network interface under different plugging and unplugging speeds and forces, including pin deformation and contact point wear.
[0077] For example, such as Figure 8-9 As shown, the bent rod 15 exerts a third-direction clamping force on the spring contact 22 of the crystal head 2. Before the crystal head 2 is inserted into the network interface 31, the free end of the bent rod 15 presses against the first position 221 of the spring contact 22. This first position 221 is the highest point on the spring contact 22. When the first drive mechanism 11 pushes the crystal head fixing seat 12, thereby driving the crystal head 2 to move towards the network interface 31, the free end of the bent rod 15 moves down from the highest point (first position) of the spring contact 22 until the crystal head 2 is fully inserted into the network interface 31, at which point the spring contact 22 engages and locks with the slot inside the network interface. At this time, the free end of the bent rod 15 moves to the second position 222 of the spring contact 22, as shown. Figure 10-11 As shown, the second position 222 is at the lowest point of the spring contact relative to the first position 221, and at this time, the free end of the bent rod 15 exerts no third-party clamping force on the second position 222 of the spring contact, and there is no contact between the free end of the bent rod 15 and the second position 222 of the spring contact. Then, when the first drive mechanism 11 pulls the crystal head fixing seat 12 and the crystal head 2 out of the network interface 31, it drives the bent rod 15 to move from the second position 222 of the spring contact towards the first position 221, until the free end of the bent rod moves to the first position 221 of the spring contact, restoring the third-party clamping force on the first position 221, thereby releasing the locking state between the spring contact 22 of the crystal head and the slot in the network interface. Then, as the first output end 111 of the first drive mechanism 11 continues to pull, the crystal head 2 is pulled out of the network interface 31; thus completing one insertion / removal test. Repeating this operation can complete the test of the network interface insertion / removal lifespan.
[0078] In some embodiments, such as Figure 6-7 As shown, the crystal head mounting bracket 12 includes:
[0079] The bottom clamp 121 is used to support the crystal head body 21;
[0080] The elastic limiting component 122 is connected to the bottom clamping plate 121. The elastic limiting component 122 is used to limit the displacement of the crystal head body 21 on the bottom clamping plate 121 along the first direction, the second direction, and the third direction. In this embodiment, by setting the bottom clamping plate 121 and the elastic limiting component 122, the crystal head body 21 can be fixed in the first direction, the second direction, and the third direction while supporting the crystal head body 21, thus limiting the movement of the crystal head body. This ensures the stability of the test process and the accuracy of the test results when the testing device 1 drives the crystal head 2 to perform plug-in and unplug tests on the network interface 31.
[0081] Furthermore, such as Figure 6-7 As shown, the elastic limiting component 122 includes,
[0082] The bottom limiting strip 1221 is provided on the bottom clamping plate 121.
[0083] The bottom limiting plate 1222 is disposed on the bottom clamping plate 121 at a distance from the bottom limiting strip 1221. The bottom limiting plate 1222 is used to cooperate with the bottom limiting strip 1221 to limit the displacement of the crystal head body 21 in the first direction.
[0084] The top movable clamp 1223 is connected to the bottom clamp 121 through the first elastic member 1224. The top movable clamp 1223 is used to cooperate with the first elastic member 1224 to limit the displacement of the crystal head body 21 in a third direction.
[0085] The bottom limiting member 1227 is connected to the bottom clamping plate 121, and the bottom limiting member 1227 is used to limit the displacement of the crystal head body 21 in the second direction.
[0086] Furthermore, the crystal head fixing base 12 also includes a vertical guide rod 123, which is disposed on the bottom clamping plate 121 in a third direction. A first elastic member 1224 is sleeved on the outside of the vertical guide rod 123, and the two ends of the first elastic member 1224 are respectively connected to the top movable clamping plate 1223 and the end of the vertical guide rod 123 away from the bottom clamping plate 121.
[0087] For example, combined with Figure 4-5As shown, the bottom clamping plate 121 is used to support the RJ45 connector body 21. The bottom clamping plate 121 has a bottom limiting strip 1221 on its edge, and a bottom limiting plate 1222 is also provided on the bottom clamping plate 121 and spaced apart from the bottom limiting strip 1221. The bottom limiting plates 1222 are fixed to the bottom clamping plate 121 at intervals along a second direction. Since the dimensions of RJ45 connector bodies of the same type are uniform, when the distance between the bottom limiting strip 1221 and the bottom limiting portion 1222 is fixed, insertion and removal tests can be performed on RJ45 connectors of the same type. Of course, the distance between the bottom limiting strip 1221 and the bottom limiting portion 1222 can also be adjusted to suit the dimensions of different types of RJ45 connector bodies.
[0088] like Figure 7 As shown, the bottom clamp 121 has an L-shaped structure. The horizontal plane of the L-shape of the bottom clamp 121 is used to support and limit the displacement of the crystal head body, and the vertical plane of the L-shape of the bottom clamp 121 is used to install the elastic reset assembly 13.
[0089] For example, the top movable clamp 1223 is elastically connected to the bottom clamp 121 via the first elastic element 1224 and the vertical guide rod 123. Specifically, one end of the vertical guide rod 123 is fixedly connected to the bottom clamp 121, the first elastic element 1224 is sleeved on the outside of the vertical guide rod 123, and the top movable clamp 1223 is located below the first elastic element 1224. The top movable clamp 1223 is movably mounted on the vertical guide rod 123. The first elastic element 1224 can be a compression spring, which can form a vertical elastic clamping force on the top movable clamp 1223, thereby pressing the crystal head body 21 upward in a third direction and restricting the displacement of the crystal head body 21 in a third direction. Furthermore, since the first elastic element has elastic recovery capability, the pressure on the crystal head body can be adjusted according to the thickness of the crystal head body.
[0090] like Figure 6 As shown, a clearance opening 1226 is provided in the middle of the top movable clamp 1223 for the network cable of the RJ45 connector to pass through. The top movable clamp 1223 is connected to the bottom clamp via a first elastic member on both sides along the second direction.
[0091] For example, the bottom limiting member 1227 is provided on both sides of the crystal head body. The bottom limiting member 1227 is a bolt, which is threadedly connected to the bottom clamping plate 121, so that the end of the bolt presses against the surface of the crystal head body, thereby limiting the displacement of the crystal head body 21 in the second direction.
[0092] Furthermore, such as Figure 7As shown, since the main body 21 of the crystal head has a certain thickness, the cooperation between the bottom limiting plate 1222 and the bottom limiting strip 1221 can only limit the displacement of the lower part of the crystal head body, while the displacement of the upper part of the crystal head body is not limited. Therefore, in order to further fix the crystal head body, the crystal head fixing base 12 also includes a top limiting plate 1225, which is connected to the top movable clamping plate 1223 to further limit the displacement of the crystal head body in the first direction.
[0093] like Figure 6 As shown, the bottom of the crystal head body 21 has a protrusion 211. When the crystal head is clamped and fixed by the crystal head fixing seat, the protrusion 211 of the crystal head is placed between the bottom limiting plate 1222 and the bottom limiting strip 1221 and placed on the surface of the bottom clamping plate 121, thereby restricting the displacement of the crystal head body in the first direction. Then, the bottom limiting member 1227 is rotated so that the end of the bottom limiting member 1227 abuts against the side of the crystal head body, restricting the displacement of the crystal head body in the second direction. Finally, the top movable clamping plate 1223 is pressed against the upper surface of the crystal head body in the third direction, restricting the displacement of the crystal head body in the third direction, thereby allowing the crystal head fixing seat to clamp and fix the crystal head body. Furthermore, since the dimensions of the same type of RJ45 connector are standardized, a bottom limiting plate and a bottom limiting strip are symmetrically fixed to the bottom clamping plate, and a top limiting plate is symmetrically fixed to the top movable clamping plate. By lifting the top movable clamping plate and inserting the protrusion 211 at the bottom of the RJ45 connector into the middle of the bottom limiting plate and bottom limiting strip, the top movable clamping plate is pushed downwards by the first elastic element (compression spring), thus securing the RJ45 connector body. Simultaneously, the end of the bent rod away from the push plate presses against the highest point of the RJ45 connector's spring clip. This ensures that the RJ45 connector is securely clamped during horizontal linear movement.
[0094] In some embodiments, such as Figure 6-7 As shown, the elastic reset assembly 13 includes:
[0095] A transverse guide rod 131 is movably mounted on a bottom clamping plate 121 along a first direction, and the first end of the transverse guide rod 131 is connected to an angle adjustment assembly 14.
[0096] The limiting plate 132 is fixedly connected to the transverse guide rod 131;
[0097] A second elastic element 133 with elastic reset capability is sleeved on the transverse guide rod 131, and the two ends of the second elastic element 133 are respectively connected to the limiting plate 132 and the bottom clamping plate 121.
[0098] For example, the second elastic element 133 is a reset spring. The function of this reset spring is that when the first output end 111 of the first drive mechanism 11 drives the angle adjustment component 14 to push along the first direction, it drives the transverse guide rod 131 of the elastic reset component 13 connected thereto to move. At this time, the reset spring will have an elastic force acting on the bottom clamping plate 121 of the crystal head fixing seat 12, pushing the crystal head to move into the network interface again, thereby ensuring that the crystal head is fully inserted into the network interface.
[0099] Furthermore, the elastic reset assembly 13 also includes a limiting block 134, which is disposed at the second end of the transverse guide rod 131. By setting the limiting block 134, the transverse guide rod 131 can be prevented from falling off the bottom clamping plate 121 when it is movably inserted through the bottom clamping plate 121.
[0100] In some embodiments, such as Figure 6-7 As shown, the angle adjustment component 14 includes:
[0101] The disk 141 has a first side surface connected to the first output terminal 111, and a limiting groove 1411 is also formed on the first side surface of the disk 141.
[0102] A rotatable push plate 142 is detachably mounted on a limiting groove 1411 via a limiting screw 143. The rotatable push plate 142 is connected to the elastic reset assembly 13 and the bent rod 15.
[0103] For example, the rotatable push plate 142 is fixedly connected to the first end of the transverse guide rod 131 of the elastic reset assembly. Since the network interfaces of electronic devices, such as laptops and desktop computers, have different opening directions (the network interfaces are T-shaped structures; some laptops have the T-shaped opening facing upwards, while others have it facing downwards, and some desktop computers have it facing left or right), this application uses an angle adjustment assembly 14 to accommodate insertion and removal tests of network interfaces with different opening directions. This simulates usage under different conditions and evaluates the durability and stability of the network interface. Specifically, the rotatable push plate 142 can be rotated and further fixed in the limiting groove 1411 of the disc 141 using the limiting screw 143, thereby adjusting the angles of the connected bent rod 15, elastic reset assembly 13, and crystal head mounting bracket 12, ultimately adjusting the insertion angle of the crystal head on the crystal head mounting bracket 12.
[0104] In some embodiments, such as Figure 1-3 As shown, the testing device 1 of this application also includes a support structure 16, which includes a support plate 161 for supporting an electronic device 3 with a network interface 31.
[0105] The second drive mechanism 162 has a second output end 1621 capable of reciprocating linear motion. The second drive mechanism 162 is mounted on the support plate 161. The second output end 1621 is used to drive the electronic device 3 to move along the first direction or the second direction.
[0106] For example, a baffle 1622 is fixed on the second output terminal 1621, and the second drive mechanism 162 is a cylinder. Electronic devices include, but are not limited to, laptops and desktop computers. Taking a laptop as an example, the laptop is placed on the support plate 161, and the second output terminal of the second drive mechanism 162 acts on the side of the laptop away from the network interface, cooperating with the first drive mechanism to perform plug-in / plug-out tests on the network interface.
[0107] In some embodiments, such as Figure 12-13 As shown, the detection device also includes a lifting structure 17, which is connected to the first drive mechanism 11. The lifting structure 17 is configured to drive the first drive mechanism 11 to reciprocate linearly along a third direction.
[0108] For example, the lifting structure 17 includes:
[0109] The lifting guide rod 171 is connected to the bearing plate 161;
[0110] An adjustable lifting block 172 is slidably connected to the lifting guide rod 171, and the adjustable lifting block 172 is connected to the first drive mechanism 11.
[0111] A lifting knob 173 is connected to an adjustable lifting block 172. The lifting knob 173 is configured to drive the adjustable lifting block to move linearly along the lifting guide rod 171.
[0112] A locking knob 174 is connected to an adjustable lifting block 172, and the locking knob 174 is configured to lock and fix the adjustable lifting block 172.
[0113] For example, a scale 175 is provided on the first side of the lifting guide rod along its length, and serrations 176 are formed on the second side of the lifting guide rod 171 along its length and at a position corresponding to the adjustable lifting block. A lifting knob 173 is rotatably connected to the adjustable lifting block 172, and one end of the lifting knob 173 is connected to a gear that meshes with the serrations 176. Therefore, by rotating the lifting knob 173, the adjustable lifting block 172 can be synchronously moved up and down along the lifting guide rod 171. The scale 175 displays the real-time height, assisting in precise adjustment. After adjustment, the position is locked by pressing the lifting guide rod with the locking knob 174.
[0114] For example, there are two lifting guide rods, and each lifting guide rod is slidably connected to an adjustable lifting block. A support plate 177 is fixedly connected between the two adjustable lifting blocks, and the support plate 177 is used to support and fix the first drive mechanism 11.
[0115] For example, the lifting structure 17 also includes a support member 178, one end of which is used to support and fix the lifting guide rod 171, and the other end of which is fixedly connected to the bearing plate 161. The lifting structure 17 is arranged opposite to the second drive mechanism 162.
[0116] This application, by incorporating a lifting structure 17, facilitates plug-in / plug-out testing of network interfaces with a certain height. Specifically, for network interfaces on laptops, such as... Figure 1-2 As shown, a laptop can be placed on a support plate, and a second drive mechanism pushes the first side of the laptop, which is opposite to the network interface. A detection device 1 is placed at the network interface. The first drive mechanism 11 of the detection device 1 drives the angle adjustment component, the elastic reset component, the crystal head fixing bracket, and the bent rod to simultaneously clamp the crystal head towards the network interface. Because the laptop's network interface is relatively low, the plug-in / plug-out test of the network interface can be completed without a lifting structure.
[0117] As for the network interface 31 of the desktop computer case, such as Figure 14-15 As shown, since the network interface 31 is relatively high, when performing plug-in / plug-out tests on the network interface 31, the lifting structure 17 is used to move the first drive mechanism 11 to the position of the network interface 31, and then the first drive mechanism 11 is used to clamp the crystal head and plug it into the network interface to complete the plug-in / plug-out lifespan test of the network interface.
[0118] Furthermore, the testing device of this application can also meet the needs of specific application scenarios: In practical applications, many users plug and unplug RJ45 connectors multiple times a day. In many industrial and commercial applications, network equipment frequently needs to be reconfigured or moved. During network deployment and troubleshooting, technicians may need to frequently plug and unplug network cables to test connections or adjust network structure. This means that RJ45 connectors are actually plugged and unplugged periodically. Equipment in these environments typically requires higher standards of reliability and durability. Therefore, the testing device of this application can test the reliability and durability of the network interface of the equipment.
[0119] Secondly, the testing device described in this application can ensure the quality of electronic equipment: for network equipment manufacturers, ensuring the durability and reliability of their products is crucial. As one of the key components connecting networks, the network interface's plug-in / plug-out lifespan directly affects the overall performance and user experience of the product. By testing the plug-in / plug-out lifespan, it can be verified that the network interface maintains good electrical performance and mechanical stability after a certain number of plug-in / plug-out cycles, thereby guaranteeing product quality.
[0120] Furthermore, many electronic products need to comply with specific industry standards or obtain relevant certifications (such as CE, FCC, etc.), and these standards may include requirements regarding the number of mating and extraction cycles of connectors. Using the testing device described in this application to perform mating and extraction life testing can help manufacturers ensure that their products comply with these regulations and avoid market access issues caused by non-compliance with standards.
[0121] Furthermore, the testing device described in this application can be used for fault prediction and prevention: by conducting plug-in / plug-out life tests on network interfaces, data can be collected to assess the expected lifespan of the network interface, which helps predict potential problems and take preventative measures. For example, the design of the network interface can be optimized based on the test results during the design phase, or reasonable usage suggestions can be provided to users during use to reduce damage caused by improper operation. In conclusion, although most ordinary users do not frequently plug and unplug network cables, from multiple perspectives such as product quality, industry standards, special application requirements, and fault prevention, plug-in / plug-out lifespan testing of network interfaces remains very necessary.
[0122] Taking the network interface of a laptop computer as an example, the testing process of the network interface 31 using the testing device 1 of this application is described in detail below:
[0123] 1) Fixing the crystal head 2: including, 1-1), before the network interface 31 is detected, placing the protrusion 211 of the crystal head body on the bottom clamping plate 121 between the bottom limiting plate 1222 and the bottom limiting strip 1221 to restrict the displacement of the crystal head body 21 in the first direction; then rotating the bottom limiting member 1227 and pressing the end of the bottom limiting member 1227 against the side of the crystal head body 21 to restrict the displacement of the crystal head body 21 in the second direction; pressing the top movable clamping plate 1223 against the upper surface of the crystal head body 21 to restrict the displacement of the crystal head body in the third direction, thereby clamping and fixing the crystal head body on the bottom clamping plate.
[0124] 1-2), control the first output end of the first drive mechanism 11 to drive the bent rod to move, so that the free end of the bent rod squeezes the spring of the crystal head at the first position 221; and the network cable of the crystal head is passed out from the clearance in the middle of the top movable clamp and the gap in the middle of the bent rod. Rotate the rotatable push plate 142 to adjust the direction of the crystal head to meet the T-shaped opening orientation of the network interface, and tighten the limit screw 143.
[0125] (ii) Calibration of the device under test position: including, 2-1) placing the device under test (e.g., a laptop or desktop computer) on the support plate; 2-2) manually adjusting the position of the device under test and adjusting the height of the crystal head through the lifting structure so that the network interface 31 of the device under test is aligned with the detection head of the detection device 1 (including the crystal head fixing base, the elastic reset component, the angle adjustment component and the bending rod).
[0126] 2-3) Manually and slowly move the device under test (DUT) towards the testing head of the testing device to smoothly insert the RJ45 connector 2 on the testing head into the network interface 31. Then, slowly move the DUT away from the testing head until the network interface of the DUT is in just-contact with the testing head of the testing device.
[0127] 2-4) Activate the second drive mechanism to make the baffle press against the device under test, mark the left and right positions of the device under test and the baffle, and mark the rising height of the detection device (which can be recorded by the scale of the lifting guide rod); then the same model does not need to be recalibrated.
[0128] (iii): Insert the RJ45 connector 2 into the network interface 31:
[0129] The first drive mechanism 11 is activated, causing the first output end 111 to synchronously drive the rotatable push plate 142, the bent rod 15, the transverse guide rod 131, the crystal head holder, and the crystal head 2 to slowly move towards the network interface 31. After the crystal head is inserted into the network interface, the first drive mechanism continues to push the rotatable push plate and the crystal head holder towards the network interface (since the user applies another push after inserting the crystal head to ensure it is fully inserted into the network interface, a push is applied here after insertion). Therefore, the detection device of this application, through the second elastic element (reset spring), has a spring force acting on the bottom clamp plate, pushing the crystal head towards the network interface again, thereby ensuring that the crystal head is fully inserted into the network interface (simulating the push applied again after manual insertion of the crystal head).
[0130] During this insertion process, the movement of the bent rod is described as follows: The free end of the bent rod 15 is originally at the first position 221 (highest point) of the spring contact of the crystal head, and the free end of the bent rod exerts a pressing force on this first position. As the rotatable push plate drives the bent rod to move towards the network interface, until the crystal head is inserted into the network interface, the free end of the bent rod 15 moves to the second position 222 (lowest point, and the free end of the bent rod is not in contact with the second position of the spring contact). At this time, the spring contact disengages from the bent rod, and the spring contact can engage and lock with the network interface.
[0131] (iv): Unplug the RJ45 connector 2 from the network interface 31:
[0132] When the RJ45 connector needs to be unplugged from the network interface, the first output end 111 of the first drive mechanism retracts, driving the rotatable push plate and the horizontal guide rod and bent rod on the push plate to move away from the network interface.
[0133] During this process, the second elastic element (reset spring) begins to reset, and the lateral guide rod moves until the limiting block contacts the bottom clamping plate. At this time, the bent rod moves from the second position 222 of the spring piece to the first position 221 and squeezes the first position, so that the spring piece is unlocked from the network interface. As the first output end continues to retract, the limiting block on the lateral guide rod drives the crystal head fixing seat to move away from the network interface, thus completing the separation of the crystal head from the network interface.
