[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0032] During the assembly process, the flexible circuit boards of electronic devices are prone to defects due to repeated folding, resulting in a high defect rate in the assembled electronic devices.

[0033] The inventors of this disclosure have discovered a testing device that can include a connecting device and a testing instrument. The connecting device can be connected to the input and output terminals of a flexible circuit board, respectively, while the testing instrument can be connected to the input and output terminals connected to the connecting device, respectively, so that the testing instrument and the input and output terminals of the flexible circuit board can form a closed loop. The testing instrument can then detect the resistance value of the flexible circuit board. If the detected resistance value meets the target range, the flexible circuit board is considered to have no defects; however, if the detected resistance value does not meet the target range, the flexible circuit board is considered to have defects, in which case it can be repaired or discarded. This reduces the defect rate of assembled electronic equipment.

[0034] Here, the determination of whether the detected resistance value meets the target range can be done manually by the testing personnel or by electronic devices with comparison functions.

[0035] This disclosure provides a testing device 100, see [link to details]. Figures 1 to 7 The testing device 100 may include a connecting device 10 and a testing instrument 20. The connecting device 10 is used to connect the input terminal 301 and the output terminal 302 of the flexible circuit board 30. The testing instrument 20 is disposed on the connecting device 10 and is used to signal connect with the input terminal 301 and the output terminal 302 so that the testing instrument 20 and the flexible circuit board 30 form a closed loop. When the testing instrument 20 and the flexible circuit board 30 form a closed loop, the testing instrument 20 is used to detect the resistance value of the flexible circuit board 30.

[0036] The connecting device 10 may have a housing 101, a first structure 102 (including a first signal connection portion as described below) for connecting the input terminal 301, and a second structure 103 (including a second signal connection portion as described below) for connecting the output terminal 302. The first structure 102 and the second structure 103 may both be exposed outside the housing 101 to facilitate direct connection to the input terminal 301 and the output terminal 302 of the flexible circuit board 30. The first structure 102 and the second structure 103 may also be disposed inside the housing 101, and the housing 101 may be provided with an openable door. When connecting the input terminal 301 and the output terminal 302 of the flexible circuit board 30, the door may be opened first, and then the first structure 102 and the second structure 103 may be connected to the input terminal 301 and the output terminal 302 respectively. The door may be opened during detection or closed when not detecting and / or during detection to protect the first structure 102 and the second structure 103. The flexible circuit board 30 can be a circuit board on electronic devices such as mobile phones and tablets. It can be a mounting and support platform for various electronic components (such as resistors, capacitors, transistors, etc.) on electronic devices. The flexible design of the flexible circuit board 30 can support the folding of electronic devices, such as foldable mobile phones and foldable computers.

[0037] The testing instrument 20 can be installed either inside or outside the connecting device 10. When installed inside the connecting device 10, the testing instrument 20 can be physically protected by the connecting device 10. The testing instrument 20 can be an instrument that measures resistance, such as a milliohmmeter.

[0038] See one example. Figure 1 and Figure 2 The testing equipment 100 may include a connecting device 10 and a testing instrument 20. The connecting device 10 includes a housing 101, with an exposed structure on the outside of the housing 101 for connecting an input terminal 301 and an output terminal 302 of a flexible circuit board 30. The testing instrument 20 is disposed within the housing 101 of the connecting device 10 and is capable of signal connection with the input terminal 301 and the output terminal 302 to form a closed loop between the testing instrument 20 and the flexible circuit board 30. When the testing instrument 20 and the flexible circuit board 30 form a closed loop, the testing instrument 20 is used to detect the resistance value of the flexible circuit board 30. The flexible circuit board 30 is a circuit board disposed on the casing of a foldable mobile phone. When the testing instrument 20 detects a resistance value, the testing personnel can manually determine whether the resistance value is within the normal range to confirm whether there are any defects in the flexible circuit board 30.

[0039] In this embodiment, the testing device 100 may include a connecting device 10 and a testing instrument 20. The connecting device 10 may be connected to the input terminal 301 and the output terminal 302 of the flexible circuit board 30, respectively. The testing instrument 20 may be connected to the input terminal 301 and the output terminal 302 connected to the connecting device 10, so that the testing instrument 20 and the input terminal 301 and the output terminal 302 of the flexible circuit board 30 can form a closed loop. Then, the testing instrument 20 can detect the resistance value of the flexible circuit board 30. If the detected resistance value is outside the normal range, the flexible circuit board 30 has a defect. At this time, the flexible circuit board 30 can be repaired or discarded, thereby reducing the defect rate of the assembled electronic equipment.

[0040] In some embodiments, see Figures 1 to 7 The connecting device 10 may include: a support structure 104, a first fixing structure 105, and a second fixing structure 106; the support structure 104 has a support surface 1041 for supporting the target device 40 on which the flexible circuit board 30 is mounted, and the flexible circuit board 30 passes through the rotating shaft of the target device 40; the first fixing structure 105 and the second fixing structure 106 are respectively connected to the support structure 104 and are both located on the support surface 1041; the first fixing structure 105 is used to connect to the input end 301 of the flexible circuit board 30, and the second fixing structure 106 is used to connect to the output end 302 of the flexible circuit board 30.

[0041] The supporting structure 104 can be a plate, the upper surface of which can be the supporting surface 1041; it can also be as follows: Figure 1 The shell 101 shown has an internal space. The upper surface of the shell 101 can be a support surface 1041; it can also be other structural forms. The support surface 1041 can support and install the target device 40 (such as a mobile phone, computer, etc.) with the flexible circuit board 30. Since the flexible circuit board 30 passes through the pivot of the target device 40, the flexible circuit board 30 and the pivot cooperate to allow the target device 40 to be folded to form a foldable mobile phone, foldable computer, etc.

[0042] In either the first fixing structure 105 or the second fixing structure 106, the fixing structure can be connected to the support surface 1041 of the support structure 104 by means of screws, welding, or other connection methods. After the first fixing structure 105 and the second fixing structure 106 are connected to the flexible circuit board 30, the input terminal 301 and the output terminal 302 of the flexible circuit board 30 can be in the same plane or in different planes, as shown in the example below. Figure 2 When the input end 301 and output end 302 of the flexible circuit board 30 are connected to the connecting device 10, the flexible circuit board 30 is in a bent state so that the input end 301 and output end 302 of the flexible circuit board 30 are in different planes.

[0043] In this embodiment, the connecting device 10 may include a support structure 104, a first fixing structure 105, and a second fixing structure 106. The support structure 104 can support the first fixing structure 105 and the second fixing structure 106. The first fixing structure 105 and the second fixing structure 106 can be respectively connected to the input terminal 301 and the output terminal 302. In this way, the input terminal 301 and the output terminal 302 of the flexible circuit board 30 can be supported more stably by the support structure 104, the first fixing structure 105, and the second fixing structure 106, thereby making the detection signal of the detection instrument 20 more stable.

[0044] In some embodiments, see Figures 1 to 7 The first fixing structure 105 may include: a first fixing member 1051 and a first groove 1052. The first fixing member 1051 is disposed on the support surface 1041. The first groove 1052 is provided with a first signal connection part that is connected to the detection instrument 20. An input terminal 301 inserted into the first groove 1052 is connected to the first signal connection part. The second fixing structure 106 may include: a second fixing member 1061 and a second groove 1062. The second fixing member 1061 is disposed on the support surface 1041. The second groove 1062 is provided with a second signal connection part that is connected to the detection instrument 20. An output terminal 302 inserted into the second groove 1062 is connected to the second signal connection part.

[0045] The first fixing member 1051 can be plate-shaped, column-shaped, or other shapes; the first groove 1052 can be provided on the surface of the first fixing member 1051 facing away from the support surface 1041, or on other surfaces of the first fixing member 1051. The second fixing member 1061 can be plate-shaped, column-shaped, or other shapes; the second groove 1062 can be provided on the surface of the second fixing member 1061 facing away from the support surface 1041, or on other surfaces of the second fixing member 1061.

[0046] In one example, both the first fixing member 1051 and the second fixing member 1061 are plate-shaped, and both the first fixing member 1051 and the second fixing member 1061 are connected to the support surface 1041 at an incline relative to the support surface 1041, such that the plane containing the surface of the first fixing member 1051 facing away from the support surface 1041 and the plane containing the surface of the second fixing member 1061 facing away from the support surface 1041 form an obtuse angle; a first groove 1052 is provided on the side of the first fixing member 1051 facing away from the support surface 1041 to insert the input terminal 301, and a second groove 1062 is provided on the side of the second fixing member 1061 facing away from the support surface 1041 to insert the output terminal 302. In this way, the flexible circuit board 30 connected to the connecting device 10 can be in a bent posture.

[0047] In one example, the first fixing member 1051 and the second fixing member 1061 can both be prisms with a triangular cross-section. When the first fixing member 1051 and the second fixing member 1061 are connected to the support surface 1041, one axial side surface of the first fixing member 1051 is connected to the support surface 1041, and one axial side surface of the second fixing member 1061 is connected to the support surface 1041. The other axial side surface of the first fixing member 1051 is provided with a first groove 1052, and the other axial side surface of the second fixing member 1061 is provided with a second groove 1062, so as to insert the input terminal 301 and the output terminal 302 respectively. In this way, the flexible circuit board 30 connected to the connecting device 10 is in a bent posture.

[0048] In this embodiment, when the first groove 1052 of the first fixing structure 105 is inserted into the input end 301 of the flexible circuit board 30, the input end 301 is fixed relative to the first groove 1052; when the second groove 1062 of the second fixing structure 106 is inserted into the output end 302 of the flexible circuit board 30, the output end 302 is fixed relative to the second groove 1062; thus, the detection signal during the detection process is more stable. Furthermore, the input terminal 301, which is inserted into the first groove 1052, is connected to the first signal connection part, and the output terminal 302, which is inserted into the second groove 1062, is connected to the second signal connection part. When the input terminal 301 is inserted into the first groove 1052 and the output terminal 302 is inserted into the second groove 1062, the input terminal 301 of the flexible circuit board 30, the output terminal 302 of the flexible circuit board 30, and the detection instrument 20 can be conveniently connected to form a closed loop. Moreover, since the first signal connection part is located in the first groove 1052 and the second signal connection part is located in the second groove 1062, compared to the arrangement that is exposed outside the connecting device 10, the probability of the first signal connection part and the second signal connection part being damaged by collisions with other objects can be reduced.

[0049] In some embodiments, see Figures 2 to 4 The first fixing structure 105 may further include: a first flipping member 1053, which is rotatably connected to the first fixing member 1051 so as to form a first clamping space with the first fixing member 1051; the second fixing structure 106 may further include: a second flipping member 1063, which is rotatably connected to the second fixing member 1061 so as to form a second clamping space with the second fixing member 1061.

[0050] The first flipper 1053 and the first fixing member 1051 can be rotatably connected by a pivot, a hinge, or other rotating structures. The first flipper 1053 rotates relative to the first fixing member 1051 so that the first flipper 1053 and the first fixing member 1051 are opposite to each other, forming a first clamping space between the first flipper 1053 and the first fixing member 1051. The first groove 1052 corresponds to the first clamping space. Thus, one end of the flexible circuit board 30 with the input terminal 301 can be clamped between the first flipper 1053 and the first fixing member 1051, and the input terminal 301 can be inserted into the first groove 1052.

[0051] The second flipper 1063 and the second fixing member 1061 can be rotatably connected by a pivot, a hinge, or other rotating structures. The second flipper 1063 rotates relative to the second fixing member 1061 so that the second flipper 1063 and the second fixing member 1061 are opposite each other, forming a second clamping space between the second flipper 1063 and the second fixing member 1061. The second groove 1062 corresponds to the second clamping space. In this way, one end of the flexible circuit board 30 with the output end 302 can be clamped between the second flipper 1063 and the second fixing member 1061, and the output end 302 can be inserted into the second groove 1062.

[0052] In this embodiment, when the input end 301 of the flexible circuit board 30 is inserted into the first groove 1052 and the output end 302 of the flexible circuit board 30 is inserted into the second groove 1062, the portion of the flexible circuit board 30 with the input end 301 can be clamped in the first clamping space, and the portion with the output end 302 can be clamped in the second clamping space. In this way, the probability of the input end 301 and the output end 302 of the flexible circuit board 30 shifting relative to the first signal connection portion and the second signal connection portion during the detection process is further reduced, thereby making the detection signal more stable.

[0053] In some embodiments, see Figures 2 to 6 In the first fixing member 1051 and the first flipping member 1053, one is rotatably provided with a first hooking part 1054, and the other is provided with a first hooking member 1055 that can be adapted and connected to the first hooking part 1054. The first hooking part 1054 can rotate and hook onto the first hooking member 1055; and / or, in the second fixing member 1061 and the second flipping member 1063, one is rotatably provided with a second hooking part 1064, and the other is provided with a second hooking member 1065 that can be adapted and connected to the second hooking part 1064. The second hooking part 1064 can rotate and hook onto the second hooking member 1065.

[0054] The first hooking portion 1054 can rotate relative to the connected structure and, after rotation, hooks with the first hooking member 1055. In the hooked state, the first fixing member 1051 and the first flipping member 1053 can form a first clamping space. One of the first hooking portion 1054 and the first hooking member 1055 is on the first fixing member 1051, and the other is on the first flipping member 1053. This hooking of the first hooking portion 1054 and the first hooking member 1055, forming the first clamping space, makes the first fixing member 1051 and the first flipping member 1053 more firmly fixed. (See also...) Figure 4 As shown, the first hook 1055 is a crossbar connected to the side edge of the first fixing member 1051, and the first hook part 1054 is rotatably mounted on the first flipping member 1053 and has a barb. During the process of the first flipping member 1053 rotating towards the first fixing member 1051, the first hook part 1054 gradually approaches the crossbar, and then the barb contacts one side of the crossbar and gradually rotates along the crossbar relative to the first flipping member 1053 in the forward direction. Then, during the process of the first flipping member 1053 continuing to rotate towards the first fixing member 1051, the barb rotates in the opposite direction to the other side of the crossbar to hook the crossbar. At this time, the first hook part 1054 hooks onto the first hook 1055, and the inspection personnel or robot can rotate the first hook part 1054 relative to the first flipping member 1053 to make the barb disengage from the crossbar, so that the first flipping member 1053 can be rotated away from the first fixing member 1051.

[0055] The second hook portion 1064 can rotate relative to the connected structure and engages with the second hook member 1065 after rotation. In the engaged state, the second fixing member 1061 and the second flipping member 1063 can form a second clamping space. One of the second hook portion 1064 and the second hook member 1065 is on the second fixing member 1061, and the other is on the second flipping member 1063. By engaging the second hook portion 1064 and the second hook member 1065 to form the second clamping space, the second fixing member 1061 and the second flipping member 1063 are more firmly fixed. The second hook portion 1064 and the second hook member 1065 can be referenced to the arrangement of the first hook portion 1054 and the first hook member 1055, which will not be described again here.

[0056] In this embodiment, when the portion of the flexible circuit board 30 with the input terminal 301 is clamped in the first clamping space and the portion with the output terminal 302 is clamped in the second clamping space, the probability of deformation of the first clamping space can be reduced by the engagement of the first hook portion 1054 and the first hook member 1055, and the probability of deformation of the second clamping space can be reduced by the engagement of the second hook portion 1064 and the second hook member 1065, thereby making the detection signal more stable.

[0057] In some embodiments, see Figure 5 and Figure 6 In the first fixing member 1051 and the first flipping member 1053, one is provided with a first adsorption part 1056, and the other is provided with a first adsorption member corresponding to the first adsorption part 1056, and the first adsorption part 1056 and the first adsorption member can adsorb each other; and / or, in the second fixing member 1061 and the second flipping member 1063, one is provided with a second adsorption part 1066, and the other is provided with a second adsorption member corresponding to the second adsorption part 1066, and the second adsorption part 1066 and the second adsorption member can adsorb each other.

[0058] In the first adsorption part 1056 and the first adsorption element, one can be a magnet, and the other can be a magnet or a metal part that can be attracted by a magnet; in the second adsorption part 1066 and the second adsorption element, one can be a magnet, and the other can be a magnet or a metal part that can be attracted by a magnet.

[0059] In this embodiment, when the portion of the flexible circuit board 30 with the input terminal 301 is clamped in the first clamping space and the portion with the output terminal 302 is clamped in the second clamping space, the probability of deformation of the first clamping space can be reduced by the mutual adsorption of the first adsorption part 1056 and the first adsorption member, and the probability of deformation of the second clamping space can be reduced by the mutual adsorption of the second adsorption part 1066 and the second adsorption member, thereby making the detection signal more stable.

[0060] In some embodiments, see Figures 1 to 3 The connecting device 10 may further include: a slide rail 50 and a carrier member 60; the slide rail 50 is disposed on the support surface 1041, and partially located between the first fixing structure 105 and the second fixing structure 106 and the support surface 1041; the carrier member 60 is slidably connected to the slide rail 50, and a bearing recess 601 is provided on the surface of the carrier member 60 facing away from the support surface 1041; wherein, the sliding of the carrier member 60 relative to the slide rail 50 is such that it can switch between a first position A and a second position B; when in the first position A, the carrier member 60 is located in the first One side of both the fixing structure 105 and the second fixing structure 106 is exposed to expose the bearing recess 601 so that the target device 40 can be picked up and put down. When in the second position B, the bearing member 60 is located between the first fixing structure 105 and the second fixing structure 106 and the support surface 1041, so that the two ends of the bearing recess 601 are respectively blocked by the first fixing structure 105 and the second fixing structure 106, and the input end 301 and the output end 302 of the flexible circuit board 30 are respectively opposite to the first groove 1052 and the second groove 1062.

[0061] Here, in the first position A, the carrier 60 is located on one side of both the first fixing structure 105 and the second fixing structure 106, so that the bearing recess 601 on the carrier 60 is exposed without being blocked by the first fixing structure 105 and the second fixing structure 106, so that the target device 40 with flexible circuit board 30 to be tested can be placed into the bearing recess 601 or the target device 40 with flexible circuit board 30 that has been tested can be taken out from the bearing recess 601; and the carrier 60 can be moved to the second position B by sliding along the slide rail 50. When the carrier 60 is in the second position B, the carrier 60 is located between the first fixing structure 105 and the second fixing structure 106 and the support surface 1041, so that the two ends of the bearing recess 601 are blocked by the first fixing structure 105 and the second fixing structure 106 respectively, and the flexible circuit board 30 is in a bent state. At the same time, the input end 301 and the output end 302 of the flexible circuit board 30 are respectively opposite to the first groove 1052 and the second groove 1062.

[0062] Limiting blocks 602 can be respectively provided at both ends of the slide rail 50 along the sliding direction to limit the support member 60 located at the first position A and the second position B, thereby reducing the probability of the support member 60 disengaging from the slide rail 50. The contour of the support recess 601 can be consistent with the contour of the target device 40, so that when the target device 40 is located in the support recess 601, the inner sidewall and the inner bottom wall of the support recess 601 can respectively conform to the surface of the target device 40, thereby reducing the probability of the target device 40 located in the support recess 601 shifting during the detection process.

[0063] In this embodiment, the carrier 60 is slidably connected to the slide rail 50 on the support surface 1041, so that the carrier 60 can be switched between a first position A and a second position B. The first position A exposes the carrier recess 601 on the carrier 60 for carrying the target device 40 with a flexible circuit board 30, so as to quickly and conveniently put the target device 40 with a flexible circuit board 30 to be tested into the carrier recess 601 or take out the target device 40 with a flexible circuit board 30 after testing. The second position B can make the carrier recess 601 correspond to the lower part of the first fixing structure 105 and the second fixing structure 106, so that the input end 301 and the output end 302 of the flexible circuit board 30 located in the carrier recess 601 can be opposite to the positions of the first groove 1052 and the second groove 1062.

[0064] In some embodiments, see Figures 4 to 6The number of first grooves 1052 is two, which are respectively plugged into the first input terminal and the second input terminal of input terminal 301. The first input terminal is used to transmit radio frequency signals, and the second input terminal is used to transmit flexible line signals. The number of second grooves 1062 is two, which are respectively plugged into the first output terminal and the second output terminal of output terminal 302. The first output terminal is connected to the first input terminal and is used to transmit radio frequency signals, and the second output terminal is connected to the second input terminal and is used to transmit flexible line signals.

[0065] In other words, the flexible circuit board 30 can have two input terminals 301, namely a first input terminal and a second input terminal. The first input terminal is responsible for transmitting radio frequency (RF) signals, and the second input terminal is responsible for transmitting flexible circuit signals. The flexible circuit board 30 can also have two output terminals 302, namely a first output terminal and a second output terminal. The first output terminal is responsible for transmitting RF signals, and the second output terminal is responsible for transmitting flexible circuit signals. Thus, RF signals can be input to the target device 40 through the first input terminal, and RF signals from the target device 40 can be output through the first output terminal. Similarly, flexible circuit signals can be input to the target device 40 through the second input terminal, and flexible circuit signals from the target device 40 can be output through the second output terminal. The RF signals enable the target device 40 to have wireless connectivity, and the flexible circuit signals enable the target device 40 to support folding.

[0066] In some embodiments, the detection device 100 may further include: a processing device and a second target device. The processing device is disposed on the connecting device 10 and is signal-connected to the detection instrument 20. It is provided with a first connection portion and a second connection portion. When the resistance value does not meet the target range, the processing device can transmit target information to the first connection portion and the second connection portion respectively. The first connection portion is used to connect to the first target device having a first output area, and the first output area is used to output the target information. The second target device is disposed on the connecting device 10 and is signal-connected to the second connection portion. The second output area of ​​the second target device is exposed from the outside of the connecting device 10, and the second output area is used to output the target information.

[0067] In other words, after the testing instrument 20 completes the test, the processing device can determine whether the detected resistance value is within the target range. If it is not within the target range (indicating that the flexible circuit board 30 has a defect), the processing device can transmit the target information that the resistance value of the flexible circuit board 30 does not meet the target range to the first connection part and the second connection part respectively. The first connection part can be connected to the first target device (such as a display screen, a player, etc.) with the first output area via wireless or cable, so that the target information can be output through the first output area (such as the display area of ​​the display screen or the playback area of ​​the player), thereby making it convenient for the testing personnel to intuitively and quickly understand the test results through the first output area. The second connection part is connected to the second target device (such as a display screen, a player, etc.) provided on the connection device 10 and having the second output area via wireless or cable, so that the target information can be output through the second target device (such as the display area of ​​the display screen or the playback area of ​​the player), thereby making it convenient for the testing personnel to intuitively and quickly understand the test results through the first output area. Here, the first target device is a device independent of the detection device 100, which is connected during detection so that it can remotely receive the resistance value detected by the detection instrument 20 when it is wirelessly connected to the detection device 100. The second target device is part of the detection device 100 so that it can quickly acquire the detected resistance value.

[0068] In some embodiments, see Figure 7 The detection instrument 20 and the processing device are disposed inside the connecting device 10; the connecting device 10 is provided with a heat dissipation area 107, one side of the heat dissipation area 107 corresponds to the detection instrument 20 and the processing device, and the other side of the heat dissipation area 107 corresponds to the outside of the connecting device 10; the heat dissipation area 107 includes one or more of the following: the thickness between the two sides of the heat dissipation area 107 is less than the thickness between the inner and outer surfaces of the connecting device 10 corresponding to the outside of the heat dissipation area 107; the heat dissipation area 107 is provided with a filter screen; the heat dissipation area 107 is provided with a movable part 108.

[0069] The detection instrument 20 and the processing device are both housed inside the connecting device 10, so that the detection instrument 20 and the processing device can be physically protected by the connecting device 10. Furthermore, in order to dissipate the heat generated by the detection instrument 20 and the processing device during operation in a timely manner, a heat dissipation area 107 is provided on the connecting device 10, so that the heat inside the connecting device 10 can be dissipated through the heat dissipation area 107, thereby reducing the probability of heat accumulation inside the connecting device 10 affecting the normal operation of the connecting device 10.

[0070] When the thickness between the two sides of the heat dissipation area 107 is less than the thickness between the inner and outer surfaces of the connecting device 10 corresponding to the heat dissipation area 107, the time required for heat to be conducted through the heat dissipation area 107 to the outside of the connecting device 10 is less than that of the area outside the heat dissipation area 107 of the connecting device 10. This allows heat to be quickly dissipated through the heat dissipation area 107 to the outside of the connecting device 10. Furthermore, by forming the heat dissipation area 107 with a thickness less than other areas, the positions on the connecting device 10 corresponding to the heat dissipation area 107 can be non-connected, reducing the probability of dust and other impurities entering the connecting device 10. When a filter is provided in the heat dissipation area 107, the size of the pores at different positions of the filter can be the same or different. Heat inside the connecting device 10 can diffuse to the outside of the connecting device 10 through the pores, and the filter reduces the probability of particulate matter and other impurities entering the connecting device 10. When a movable part 108 is provided in the heat dissipation area 107, the movable part 108 (e.g., Figure 7 When the fan blades (as shown) are in motion, airflow can be generated to carry the heat inside the connecting device 10 to the outside of the connecting device 10 via the heat dissipation zone 107, so as to reduce the temperature inside the connecting device 10.
