[0067] The adjusting mechanism 6 includes a push plate 61, a transmission wheel 62 and a transmission plate 63. The push plate 61 is fixed to the bottom of the protective plate 41. The push plate 61 is a trapezoidal structure. One end of the transmission plate 63 is fixed to the movable clamp 34. The other end of the transmission plate 63 is rotatably connected to the transmission wheel 62. The transmission wheel 62 is arranged toward the inclined surface of the push plate 61.

[0068] A first telescopic member 8, wherein the first telescopic member 8 is arranged along the sliding direction of the slide plate 31, and two ends of the first telescopic member 8 are respectively connected to the detection box 1 and the slide plate 31;

[0069] The protective plate 41 is a transparent structure; the moving range of the protective plate 41 is located above the hanger 23; the fixed clamp 32 and the movable clamp 34 are both arranged on the same horizontal plane as the hanger 23.

[0070] In this embodiment, please refer to Fig.10 (a), the hanger 23 is used to hang the end of the terminal block 10, and the cable portion of the terminal block 10 is installed in the clamping range of the fixed clamp 32 and the movable clamp 34; when the terminal block 10 needs to be subjected to a tensile force test, the movable clamp 34 clamps the cable portion of the terminal block 10 on the fixed clamp 32.

[0071] It can be understood that the top opening of the detection box 1 provides space for installing or removing the wiring terminal 10 .

[0072] In this embodiment, the camera 43 is used to monitor the state of the connection between the cable portion and the end portion during the tension detection of the connection terminal 10 .

[0073] The camera 43 includes two use positions:

[0074] The camera 43 is retracted into the detection box 1, and the protective plate 41 is separated from the bracket 23, so as to facilitate the installation of the end of the terminal block 10 onto the bracket 23;

[0075] At the inspection station, the camera 43 moves and is aligned with the connection between the bracket 23 and the end of the terminal block 10 , and the protective plate 41 blocks the top of the bracket 23 to provide a safety protection function for the terminal block 10 during tension inspection.

[0076] The camera 43 is installed on the transparent protective plate 41 through the installation frame 42, and the protective plate 41 is moved and adjusted by the moving mechanism 5, so that the camera 43 can be moved and adjusted between different workstations to facilitate the installation, detection and removal of the terminal block 10.

[0077] Please refer to Figure 1 and Figure 2 The terminal tension detection device further includes a display screen 7, the display screen 7 is connected to the tension detection member 21 by signal, and the display screen 7 is connected to the camera 43 by signal.

[0078] The display screen 7 is a touch screen, which provides support for touch operation and data display when performing tension testing. The camera 43 is used to display and record the image information during tension testing when collecting and identifying the end of the terminal 10 .

[0079] Detection principle:

[0080] First, hang the end of the terminal block 10 on the hanger 23, and then assemble the cable portion of the terminal block 10 between the fixed fixture 32 and the movable fixture 34;

[0081] The moving mechanism 5 is started, and the moving mechanism 5 drives the protective plate 41 to move, and the protective plate 41 drives the camera 43 to switch from the avoidance position to the detection position. The protective plate 41 moves and drives the push plate 61 to move, and the push plate 61 moves and contacts the transmission wheel 62. The transmission wheel 62 stretches adaptively after being pressed, and when the transmission wheel 62 stretches, the cable part of the terminal block 10 is stably clamped on the fixing fixture 32;

[0082] A preset tension is applied to the clamped terminal 10 through the first telescopic member 8 to start the tension test. During the tension test, the protective plate 41 is blocked within the range of the hanger 23 to provide safety protection for the end of the terminal 10 during the tension test. Finally, under the action of a moving mechanism 5, the station switching of the camera 43 and the clamping of the terminal 10 are synchronously achieved, and the tension test situation can be determined through the picture situation monitored by the camera 43, thereby improving the comprehensiveness and accuracy of the test data.

[0083] It can be understood that the preset pulling force applied is the safety testing pulling force for qualified products.

[0084] Shooting principle:

[0085] When the camera 43 moves to the detection station, the camera 43 is started, and the image acquisition range of the camera 43 is aligned with the connection between the end of the hanger 23 and the terminal 10 and the cable part, and the tension detection situation can be determined by the monitored image situation;

[0086] When the connection terminal 10 is disconnected, the camera 43 can quickly identify and record the disconnection;

[0087] When the connection terminal 10 is broken but not disconnected, the camera 43 can quickly identify and record the image information of the degree of the breakage, and it is determined that the tension test is unqualified;

[0088] When the connecting terminal 10 is not broken, the camera 43 can quickly identify and record that the tension test of the connecting terminal 10 is normal, and then determine that the tension test is qualified.

[0089] Please refer to Figure 2 and Figure 4 The detection mechanism 4 also includes a coding device 44, which is installed on the protective plate 41 through the installation frame 42. A connecting port 410 is opened on the protective plate 41, and the spraying end of the coding device 44 is aligned with the connecting port 410.

[0090] When the camera 43 is at the detection position, the coding device 44 is aligned with the cable portion of the connection terminal 10 .

[0091] When the camera 43 detects that the wiring terminal 10 fails the tension test, the coding device 44 codes the cable through the connection port 410 to distinguish whether the tested wiring terminal 10 is qualified, which is beneficial for subsequent identification and statistics, and prevents unqualified products from entering the market.

[0092] Preferably, two nozzles are provided on the coding device 44. The two nozzles are used to spray marking pigments of different colors respectively.

[0093] Specifically, each of the nozzles is equipped with an independent liquid storage tank and a spray pump. The spray pump extracts the spray paint in the liquid storage tank and transports it to the nozzle for spraying, and the spray paint is sprayed onto the cable part of the detected terminal block 10 through the nozzle, so as to facilitate automatic marking and recording of the terminal block 10 after detection.

[0094] The liquid storage bin is provided with a liquid filling port, which is convenient for adding and replenishing the spray paint inside the liquid storage bin.

[0095] The two nozzles are provided for spraying paints of different colors, and are convenient for distinguishing and marking the cable parts of the qualified and unqualified wiring terminals 10 to distinguish whether the wiring terminals 10 have been subjected to tension testing.

[0096] Please refer again Figure 1 In this embodiment, a sliding frame is provided on the detection box 1, and the slide plate 31 is slidably installed in the sliding frame to provide stable support and limiting effect for the movement and adjustment of the slide plate 31.

[0097] Please refer to Figure 1 and Figure 3 The clamping surface between the fixed clamp 32 and the movable clamp 34 is an arc-shaped structure.

[0098] The clamping surfaces between the fixed clamp 32 and the movable clamp 34 need to be roughened to increase the clamping force. Fig.10The movable clamp 34 and the fixed clamp 32 use an arc-shaped clamping surface to increase the friction during tension testing and improve the stability of the cable portion of the terminal block 10 after clamping.

[0099] When the movable clamp 34 is separated from the fixed clamp 32 , a movable space is provided for the installation of the cable part of the terminal block 10 ; when the movable clamp 34 is docked with the fixed clamp 32 , support is provided for the clamping of the cable part of the terminal block 10 .

[0100] In an optional implementation of the present embodiment, the moving mechanism 5 can be an electric telescopic rod, the fixed end of the moving mechanism 5 is fixedly arranged in the detection box 1, and the telescopic end of the moving mechanism 5 is fixedly connected to the protective plate 41, so that the protective plate 41 can be directly driven to move and adjust conveniently through the moving mechanism 5.

[0101] In another optional implementation of this embodiment, please refer to Figure 2 and Figure 3 The moving mechanism 5 includes a motor 51, a screw rod 52 and a moving member 53. The motor 51 is fixed on the detection box 1, the screw rod 52 is fixed on the rotating shaft end of the motor 51, the moving member 53 is threadedly connected to the screw rod 52, the top of the moving member 53 is fixedly connected to the protective plate 41, and the bracket 23 is located between the screw rod 52 and the pushing plate 61.

[0102] In this embodiment, the motor 51 provides power for the movement and adjustment of the movable member 53 through the screw rod 52, so that the protective plate 41 can stably telescope and move, thereby providing stable power for the movement and adjustment of the camera 43 and the inkjet device 44.

[0103] Specifically, a track groove is provided on the detection box 1 , and the protective plate 41 is inserted into the track groove and is slidably connected with the detection box 1 , thereby providing stable support for the horizontal movement adjustment of the protective plate 41 and the moving member 53 .

[0104] Please refer to Figure 1 and Figure 3 The hanger 23 is provided with a plurality of hanging openings of different sizes. The hanging openings are used to hang the ends of the wiring terminals 10 to be tested.

[0105] The bracket 23 is rotatably connected to the mounting seat 22 to facilitate the adjustment of different hanging openings. It can be understood that a fixing part can be provided to limit the rotation of the bracket 23 and the mounting seat 22 after the bracket 23 is rotated and adjusted to a matching position.

[0106] A plurality of hanging openings of different sizes can adapt to the installation of the ends of the connecting terminals 10 of different sizes, so that different hanging openings can be selected for tension testing according to the requirements of the end size of the connecting terminals 10, and are suitable for tension testing of the connecting terminals 10 of different sizes.

[0107] In this embodiment, the first telescopic member 8 may be a hydraulic telescopic rod. The fixed end of the first telescopic member 8 is fixed in the detection box 1, and the telescopic end of the first telescopic member 8 is fixed on the slide plate 31. The first telescopic member 8 is convenient for controlling the slide plate 31 to move and adjust, and provides independent power support for the tension detection of the terminal block 10.

[0108] The working principle of the terminal tension detection device provided in this embodiment is as follows:

[0109] Before using the device, the protective plate 41 is retracted in advance to open the installation range of the bracket 23, the end of the terminal block 10 is hung on the bracket 23, and the cable part of the terminal block 10 is inserted into the clamping range of the fixed clamp 32 and the movable clamp 34;

[0110] A1, after the terminal block 10 is installed, the motor 51 is started, the motor 51 drives the screw rod 52 to rotate, the screw rod 52 drives the moving member 53 to move, the moving member 53 drives the protective plate 41 to extend, and when the protective plate 41 extends, it simultaneously drives the camera 43 and the inkjet device 44 to move, so that the camera 43 moves from the avoidance position to the detection position, and the inkjet device 44 moves to the cable part of the terminal block 10 synchronously;

[0111] A2, while the protective plate 41 moves, the protective plate 41 also synchronously drives the push plate 61 to extend, and while the push plate 61 extends, it gradually fits with the transmission wheel 62, and the transmission wheel 62 is pushed and extended by the push plate 61, and the transmission wheel 62 drives the movable clamp 34 to extend through the transmission plate 63, and the movable clamp 34 clamps the cable part on the fixed clamp 32, so as to realize automatic clamping of the cable part of the terminal block 10;

[0112] A3, after the terminal block 10 is clamped and the camera 43 moves to the detection station, the first telescopic member 8 is started, and the first telescopic member 8 drives the clamping mechanism 3 to contract as a whole; the terminal block 10 starts to perform tension detection, and the tension detection member 21 detects the tension when the mounting seat 22 and the hanger 23 are pulled, until the tension data detected by the tension detection member 21 reaches a preset tension value, the tension is maintained to a preset detection time, and the camera 43 is used to monitor whether the terminal block 10 is qualified during tension monitoring;

[0113] A4, when the tension monitoring of the terminal block 10 is qualified, the coding device 44 performs coding marking (blue paint) on the cable;

[0114] When the tension test of the connecting terminal 10 fails, the coding device 44 performs coding marking (red paint) on the cable;

[0115] A5. After the detection is completed, the clamping mechanism 3 is reset by controlling the first telescopic member 8; the moving mechanism 5 controls the contraction of the protective plate 41 to realize the reset of the camera 43 and the inkjet device 44. While resetting, the protective plate 41 drives the push plate 61 to contract and reset, and the movable clamp 34 automatically contracts and resets under the action of the elastic contraction member 33, so as to realize the loosening of the cable, which is convenient for detection and the loosening of the cable after marking.

[0116] Finally, under the action of a mobile mechanism 5, the station switching of the camera 43 and the clamping of the terminal block 10 are realized synchronously, and the tension detection situation can be determined by the picture situation monitored by the camera 43, thereby improving the comprehensiveness and accuracy of the detection data.

[0117] Second embodiment

[0118] Please refer to Figures 5 to 8 Based on the terminal tension detection device provided by the first embodiment of the present invention, the second embodiment of the present invention provides another terminal tension detection device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0119] Specifically, the difference of the terminal tension detection device provided by the second embodiment of the present invention is that the first telescopic member 8 is an elastic support structure;

[0120] The detection mechanism 4 further includes a second contraction member 45 and a docking plate 46, wherein the second contraction member 45 is fixedly mounted on the top of the protective plate 41, the mounting frame 42 is mounted on the telescopic end of the second contraction member 45, and the mounting frame 42 is slidably mounted on the protective plate 41, and the docking plate 46 is fixedly mounted on the bottom of the protective plate 41;

[0121] The terminal tension detection device further comprises a limiter 9 , which is fixed on the detection box 1 and disposed toward the installation frame 42 .

[0122] When the docking plate 46 moves following the protection plate 41 , the docking plate 46 abuts against the slide plate 31 and continues to push the slide plate 31 to move as a whole.

[0123] While the protective plate 41 drives the camera 43 to switch from the avoidance position to the detection position, the protective plate 41 can also synchronously drive the docking plate 46 to move, so that after the movable clamp 34 is clamped on the fixed clamp 32, the protective plate 41 can also push the slide plate 31 to move through the docking plate 46, providing power for the movement adjustment of the slide plate 31.

[0124] In this embodiment, the second contraction member 45 and the docking plate 46 cooperate with each other to control the camera 43 to remain within the range of the detection station and to maintain the coding device 44 aligned with the surface of the cable while the slide plate 31 moves.

[0125] Please refer to Fig.11 and Fig. 9 Specifically, when the camera 43 is moved and adjusted to the detection position, the limit member 9 is aligned with the surface of the installation frame 42, and the docking plate 46 is docked on the slide plate 31; the moving mechanism 5 can also continue to drive the protection plate 41 to move. When the protection plate 41 moves, on the one hand, the slide plate 31 is pushed to move by the docking plate 46 to provide tension for the tension detection of the terminal 10; on the other hand, the limit member 9 maintains the installation frame 42, the camera 43 and the inkjet device 44 as a whole at the detection position;

[0126] Ultimately, the switching of the protective plate 41 position, the clamping of the movable clamp 34 and the tension detection of the terminal 10 are achieved in sequence under the same power drive; when the protective plate 41 drives the camera 43 to switch from the avoidance position to the detection position, the automatic clamping of the movable clamp 34 is simultaneously achieved; when the clamping of the movable clamp 34 is completed, the protective plate 41 can continue to provide continuous detection tension for the terminal 10 in the clamped state.

[0127] The docking plate 46 can be fixedly arranged at the center of the protective plate 41 and located above the hanger 23. At this time, it is necessary to adjust the height difference between the protective plate 41 and the hanger 23 to prevent the docking plate 46 from touching the hanger 23.

[0128] Please refer again Fig.10 The docking plate 46 may also be disposed between the pushing plate 61 and the detection box 1 .

[0129] The working principle of the terminal tension detection device provided in this embodiment is as follows:

[0130] like Fig. 9 (a) Fig.10 (a) and Fig.11As shown in (a), it may be defined that in the initial state, the camera 43 is in the avoidance position, the movable clamp 34 is in the extended state, and the second retractable member 45 is in the retracted state;

[0131] Please refer to Fig. 9 (a) to Fig. 9 (c) When the position of the camera 43 needs to be adjusted, the motor 51 is started, the motor 51 drives the screw rod 52 to rotate, the screw rod 52 drives the moving member 53 to extend, the moving member 53 drives the protective plate 41 to extend when extending, and the protective plate 41 drives the mounting frame 42, the camera 43 and the inkjet device 44 to extend as a whole, so that the camera 43 moves from the avoidance position to the detection position and is aligned between the bracket 23 and the terminal 10;

[0132] Please refer to Fig.10 (a) to Fig.10 (c), while the protective plate 41 moves, the protective plate 41 drives the push plate 61 to move synchronously, and when the push plate 61 moves, the inclined surface structure on the push plate 61 contacts the transmission wheel 62. When the push plate 61 continues to move, the push plate 61 pushes the transmission plate 63 to extend through the transmission wheel 62, and the transmission plate 63 drives the movable clamp 34 to extend and clamp the cable until the cable of the terminal block 10 is clamped and locked between the movable clamp 34 and the fixed clamp 32;

[0133] Please refer to Fig. 9 and Fig.11 , while the protective plate 41 moves, the docking plate 46 is also driven to move synchronously, and the docking plate 46 gradually approaches the slide plate 31 while moving. When the camera 43 is completely moved to the detection position, the docking plate 46 fits with the slide plate 31, and the mounting frame 42 moves with the protective plate 41 while abutting against the limiter 9;

[0134] like Fig. 9 (c) Fig.10 (c) and Fig.11 As shown in (b), the camera 43 is in the detection position, the movable clamp 34 is in the clamping state, and the second contraction member 45 is in the contracted state;

[0135] Please refer to Fig.11 (b) to Fig.11(c) When the camera 43 is in the detection position, the movable member 53 can continue to drive the protective plate 41 to extend, and the camera 43 and the inkjet device 44 remain stationary at the detection position. The protective plate 41 drives the push plate 61 and the docking plate 46 to continue to extend, so that the movable clamp 34 is maintained in a clamped state, and the protective plate 41 provides the sliding plate 31 with a tensile force for tensile force detection through the docking plate 46.

[0136] Finally, under the action of the same power drive, the camera 43 position is switched in sequence, the movable clamp 34 is automatically clamped and the slide plate 31 moves to provide the detection tension; when the camera 43 switches from the avoidance position to the detection position, the movable clamp 34 is automatically clamped; while the camera 43 is maintained at the detection position, the protective plate 41 can continue to drive the clamped terminal 10 to perform tension detection.

[0137] The invention also provides a power distribution cabinet system.

[0138] See also Fig.12 , the power distribution cabinet system includes a power distribution cabinet, a monitoring and recording module and the terminal tension detection device;

[0139] The monitoring and recording module is installed in the power distribution cabinet, and the monitoring and recording module is used to monitor the usage status of each component in the power distribution cabinet;

[0140] The terminal tension detection device is signal-connected to the monitoring and recording module.

[0141] In this embodiment, after the terminal detection device performs a sampling tensile test on a batch of terminal blocks 10, the test data is sent to the monitoring and recording module. After judging that the batch is qualified, the distribution cabinet is installed with the terminal blocks 10 belonging to the same batch. The components in the distribution cabinet also include the terminal blocks 10.

[0142] During the use of the power distribution cabinet, the monitoring and recording module can monitor the use status of each component in the power distribution cabinet. In a specific aspect, the monitoring and recording module monitors the use status of the terminal block 10 in the power distribution cabinet; the use monitoring data of the terminal block 10 can be combined with the tension detection data for analysis, providing technical support for the subsequent evaluation and analysis of the overall quality of the terminal block 10 product.
