Description

Technical Field

[0001] The present invention relates to the technical field of terminal connectors, and particularly relates to a composite terminal connector and a detection jig therefor. Background Art

[0002] A composite terminal connector is a connector widely used in the field of electrical connection. Composite terminal connectors are widely used in the automotive industry, especially in high-current and low-frequency signal transmission. They have excellent structural strength and electrical safety, ensuring a firm connection and not easily falling off. Such connectors usually adopt high-quality conductive materials and advanced contact designs to ensure the stability and safety of current transmission, effectively reducing the circuit contact resistance and improving the power utilization rate.

[0003] With excellent performance, the composite terminal connector often also requires continuous innovation in its production technology and detection technology.

[0004] For example, Chinese Patent No. CN116068323A discloses a metal terminal connector and a connector test assembly. The metal terminal connector includes a terminal, a pin, and a positioning piece; when testing the above metal terminal connector, a special connector test assembly is required. The connector test assembly includes a workbench, a terminal seat, a transmission part, and a test part; it can solve the following problems existing in the prior art during the terminal test: only involving the plugging between the terminal and the electronic product, unable to test the locking force between the terminal and the electronic product, and further unable to test whether the terminal can be smoothly pulled out after plugging in actual application, thus having limitations; the friction between the lower clamp seat and the terminal is small, resulting in a poor fixing effect on the terminal, and moreover, if the locking force between the terminal and the electronic product is too large, the lower clamp seat is prone to slide relative to the terminal and cannot pull out the terminal, and the terminal is easily stuck in the electronic product, thereby affecting the test efficiency.

[0005] However, the above connector test assembly still has some deficiencies in the actual use process:

[0006] 1. First, the above terminals are repeatedly inserted and removed in the terminal seat, which is convenient for automatically testing multiple terminals at one time. However, it can only detect a single type of terminal. If the number of pins of different terminals is inconsistent, it cannot be tested for them. Further, it is also impossible to detect terminals of different sizes, resulting in a certain degree of singularity and poor applicability.

[0007] 2. In addition, during the plugging and unplugging process of the terminal, the plugging and unplugging depth always remains the same, and it is impossible to detect whether different plugging and unplugging depths will affect the terminal connector. Thus, it is impossible to simulate the situation where the plugging and assembling are not in place in daily life and further detect its contact performance to see if it will lead to poor contact.

[0008] Therefore, under the viewpoints stated above, there is still room for improvement in the existing detection components. Summary of the Invention

Detailed implementation manners

[0046] The following further elaborates on this application Figures 1 - 16 in conjunction with the attached drawings.

[0047] The embodiment of this application discloses a composite terminal connector and its detection fixture; it relates to a composite terminal connector and a detection fixture for the above-mentioned type of composite terminal connector; this composite terminal connector is mainly applied in the electronics industry.

[0048] First, multiple existing terminals are repeatedly inserted and removed simultaneously, which facilitates automated testing of multiple terminals at one time. However, it can only detect a single type of terminal. If the number of pins of different terminals is inconsistent, it cannot be tested for them. Further, it is also impossible to detect terminals of different sizes, resulting in a certain degree of singularity and poor applicability.

[0049] Secondly, during the insertion and removal of the terminals, the insertion and removal depth always remains the same, and it is impossible to detect whether different insertion and removal depths will affect the terminal connector, so as to simulate the situation of incomplete insertion and assembly in daily life and further detect its contact performance and whether it will cause poor contact.

[0050] Therefore, this application proposes a composite terminal connector and its detection fixture.

[0051] Embodiment 1:

[0052] Refer to Figure 1 and Figure 12As shown in the figure, the present application relates to a composite terminal connector, which includes a stationary housing 1. Right-angled through holes 10 are formed on both sides of the housing 1 and are vertically distributed. Two groups of metal connectors 11 are arranged in the right-angled through holes 10 of the housing 1. The metal connectors 11 are distributed at right angles, and extension metal plates 12 that integrally extend and bend outward are provided at both ends of the metal connectors 11 close to the right-angled through holes 10 of the housing 1, and the extension metal plates 12 abut against the right-angled through holes 10. Terminals installed in the right-angled through holes 10 are integrally provided at both ends of the two metal connectors 11.

[0053] The housing 1 in the present application is made of insulating material, which can ensure the stability of the metal connectors 11 and terminals inside it; and high-quality conductive materials and advanced contact designs are adopted to ensure the stability and safety of current transmission. This design effectively reduces the circuit contact resistance, reduces power consumption, and improves the power utilization rate.

[0054] Moreover, the metal connectors 11 are right-angled, and the terminal structures at both ends are the same, which can ensure that electronic components can be randomly inserted into any position at both ends, ensuring the diversity of electronic component connections.

[0055] Furthermore, the housing 1 protects the metal connectors 11 and terminals, enabling them to operate stably for a long time in harsh environments, having high drop resistance, and thus extending the service life; then, it can also adapt to different application scenarios, including environmental conditions such as high temperature and vibration, ensuring good performance under various conditions.

[0056] Refer to Figure 2 and Figure 3 As shown in the figure, it is a schematic structural diagram of the connection between the metal connectors 11 in the housing 1 of the present application and external electronic components; a limiting piece 14 is also arranged in the right-angled through hole 10 of the housing 1. The limiting piece 14 is slidably arranged in the right-angled through hole 10, and a limiting compression spring 15 is arranged between the end of the limiting piece 14 far from the extension metal plate 12 and the inner wall of the housing 1. A right-angled sliding plate 16 is also connected to the end of the limiting piece 14 close to the limiting compression spring 15. The right-angled sliding plate 16 is slidably arranged in the housing 1, and one end of the right-angled sliding plate 16 slidably penetrates the housing 1 for external force control.

[0057] When a connection operation is required, when inserting the connecting wire of an external electronic component into the right-angled round hole on the base body 1, first pull the right-angled slide plate 16 on the base body 1 so that the right-angled slide plate 16 drives the limit piece 14 away from the metal connecting piece 11 and the extended metal plate 12, making an insertion area convenient for inserting the connecting wire of the external electronic component between the metal connecting piece 11 and the limit piece 14. Then, after inserting the connecting wire of the electronic component into the insertion area, release the right-angled slide plate 16, and the limit compression spring 15 on the back side of the right-angled slide plate 16 squeezes the right-angled slide plate 16 and the limit piece 14, so that the connecting wire of the electronic component is clamped between the limit piece 14 and the metal connecting piece 11.

[0058] It should be noted that the limit piece 14 is of an insulating structure; and the elastic force of the limit compression spring 15 is relatively large; the electronic component is a known external structure, and its connecting wire is used for power supply.

[0059] The connection method of the existing composite terminal connector is relatively complex, and it mainly realizes the connection of the connecting wire of the electronic component through the deformation of the metal part, while the present application realizes the clamping of the connecting wire of the electronic component through an elastic clamping method, so as to realize the quick connection and disassembly of the connecting wire of the electronic component. This can not only ensure the connection efficiency but also maintain the connection stability, and avoid the connecting wire of the electronic component from falling off.

[0060] For the above-mentioned composite terminal connector, the present application also provides a detection fixture specifically for the above-mentioned composite terminal connector.

[0061] Refer to Figure 4 As shown, the detection fixture of the composite terminal connector includes a static detection platform 2. An integrally arranged placement card board 20 is vertically distributed on the detection platform 2. A mounting base 3 for clamping and installing the base body 1 of the composite terminal connector is slidably arranged on one side of the placement card board 20. A detector 4 for power-on detection of the composite terminal connector arranged on the mounting base 3 is also provided on the detection platform 2.

[0062] First, the detection platform 2 is arranged on the ground. The mounting base 3 arranged on the placement card board 20 can slide laterally and can install composite terminal connectors of different sizes and different dimensions.

[0063] The detector 4 can perform automatic plugging and unplugging tests on composite terminal connectors of different sizes and different dimensions, detect the durability of the composite terminal connector, and the stability of the electrical signal during the plugging and unplugging process. Similarly, it can also detect the contact performance of the metal connecting piece 11 of the composite terminal connector and detect whether it is prone to poor contact.

[0064] Refer to Figure 5 、 Figure 6 and Figure 7As shown, the mounting base 3 includes a horizontal guide rail 30 provided on the placing card board 20. A sliding horizontal sliding frame 31 is provided on the horizontal guide rail 30. Along the length direction of the horizontal sliding frame 31, a number of strip clamping plates 32 are equidistantly installed for mounting the seat body 1. An inverted chamfer 33 is provided on the strip clamping plate 32.

[0065] An adjusting screw rod 34 is also rotatably connected to the horizontal sliding frame 31 through a bearing. The strip clamping plates 32 are symmetrically screwed onto the adjusting screw rod 34.

[0066] In this application, the horizontal guide rail 30 is provided on the placing card board 20, and its purpose is to ensure the horizontal movement of the horizontal sliding frame 31. When the detection of the composite terminal connector is required, the horizontal sliding frame 31 is stretched outwards so that the horizontal sliding frame 31 is away from the detection platform 2. Then, the adjusting screw rod 34 is rotated, and the position of the strip clamping plates 32 in the horizontal sliding frame 31 is adjusted through the adjusting screw rod 34, so that the distance between the strip clamping plates 32 is equal to the width of the seat body 1 of the composite terminal connector. At this time, the seat body 1 can be slidably installed onto the inverted chamfer 33 of the strip clamping plate 32 to limit the seat body 1 of the composite terminal connector.

[0067] For the preparatory work before the detection of the composite terminal connector, when clamping composite terminal connectors of different sizes, the distance between the two strip clamping plates 32 can be adjusted.

[0068] After the composite terminal connector is clamped, first, the durability detection of the plugging and unplugging of the composite terminal connector is carried out, which is specifically as follows:

[0069] Refer to Figure 8 As shown, specifically, the detector 4 includes a detection frame 40 parallel to the placing card board 20 on the detection platform 2. A number of connection plugs 41 connected to the composite terminal connector are equidistantly installed in the detection frame 40. One end of the connection plug 41 close to the composite terminal connector is provided with a plugging detection column 42 inserted into the right-angle through hole 10 of the seat body 1. A wire 43 for power-on detection is connected to the back side of the connection plug 41. A lighting device 44 is also connected to the back side of the connection plug 41 through the wire 43 one by one. A number of lighting devices 44 are integrally arranged on the detection platform 2.

[0070] It should be noted that the connection plug 41 is a known structure, which has conductivity, and the plugging detection column 42 on the connection plug 41 is connected to the lighting device 44 through the wire 43.

[0071] Further, there are two detection frames 40 provided on the detector 4. The two detection frames 40 are vertically distributed. The detection frame 40 on the placement card 20 is provided with the same structure as that in the detection frame 40 on the detection platform 2 and can quickly replace connection plugs 41 of different models. Moreover, the insertion detection posts 42 in the detection frame 40 on the placement card 20 are also connected to the lighting device 44 integrated on the detection platform 2 through wires 43.

[0072] The internal component structures of the two detection frames 40 are the same and their functions are the same.

[0073] In the specific implementation process, when performing the insertion and extraction durability test of the composite terminal connector, the connection plug 41 in the detection frame 40 will move reciprocally in the width direction of the detection frame 40 towards the direction of the composite terminal connector. During the movement, the insertion detection post 42 of the connection plug 41 will reciprocally insert into the right-angle through hole 10 in the horizontal direction of the composite terminal connector and make reciprocal connections and separations with the terminals, metal connectors 11 and extended metal plates 12 inside it. Similarly, the right-angle through hole 10 on the vertical end of the composite terminal connector is the same as the right-angle through hole 10 in the horizontal direction.

[0074] Therefore, as the insertion detection post 42 is reciprocally inserted and extracted, the lighting device 44 on the detection platform 2 will also perform intermittent lighting and turning off operations. Until after the insertion detection post 42 is inserted and extracted a specified number of times, if the lighting device 44 can still light up normally, it indicates that the quality of the detected composite terminal connector is qualified.

[0075] If the lighting device 44 cannot light up and then the lighting device 44 is detected, in the case of determining that the lighting device 44 is not damaged, it can be determined that the quality of the detected composite terminal connector is poor and unqualified.

[0076] When it is necessary to detect the ultimate service life of the composite terminal connector, continuously perform the insertion and extraction test of the composite terminal connector until the lighting device 44 can no longer light up. Then, detect the lighting device 44. In the case of determining that the lighting device 44 is not damaged, the ultimate life detection of the composite terminal connector is completed.

[0077] When performing the insertion and extraction durability test of the composite terminal connector, multiple groups of composite terminal connectors are detected simultaneously to form a control group. Through the insertion and extraction comparison test of multiple groups of composite terminal connectors, the data of the insertion and extraction test of the composite terminal connector are compared. Firstly, it can greatly improve the accuracy of the insertion and extraction durability test results of the composite terminal connector. Secondly, it can avoid the contingency of the test results.

[0078] Further, when performing the reciprocating insertion and extraction operation of the composite terminal connector, the lighting device 44 monitors and records the intensity of the current and voltage during the detection process in real time.

[0079] Refer to Figure 9 As shown, it is a schematic structural diagram of the plugging and unplugging test of the composite terminal connector on the detection platform 2 in this application; a detection motor 60 is slidably installed at the bottom of the detection platform 2 through a motor base, and a reciprocating wheel 61 is also connected to the detection platform 2. The reciprocating wheel 61 is eccentrically connected to the output end of the detection motor 60.

[0080] One end of the connection plug 41 is provided with a linkage plate 7, and the linkage plate 7 abuts against the reciprocating wheel 61.

[0081] A horizontal linkage rack 62 is installed on the connection plug 41. One end of the horizontal linkage rack 62 away from the connection plug 41 meshes with a linkage gear 63 rotatably installed on the detection platform 2. A vertical linkage rack 64 is also vertically meshed with the linkage gear 63. The vertical linkage rack 64 is connected to a detection frame 40 sliding on the placement card board 20.

[0082] In the specific implementation process, the detection motor 60 is started, and the detection motor 60 controls the reciprocating wheel 61 to rotate. While the reciprocating wheel 61 rotates, it squeezes the connection plug 41. At the same time, with the cooperation of the return spring 57, it continuously performs the reciprocating plugging and unplugging operation on the composite terminal connector, so as to realize the power-on detection of it. Further, it can also realize the durability detection during the plugging and unplugging process of the composite terminal connector.

[0083] When testing composite terminal connectors of different models, the corresponding connection plug 41 needs to be replaced. Taking the two-hole composite terminal connector as an example in this application, if there are multiple composite terminal connectors with right-angle through holes 10, the component 5 needs to be replaced for quick replacement to improve efficiency.

[0084] Therefore, this application proposes a replacement component 5. The replacement component 5 can test composite terminal connectors of different models, and can quickly disassemble and replace the corresponding connection plug 41 according to composite terminal connectors of different models, so as to test composite terminal connectors of different models, which can greatly improve the applicability of the jig.

[0085] Specifically as follows:

[0086] Refer to Figure 10 and Figure 11As shown, a replacement component 5 for facilitating the replacement of connection plugs 41 of different models is also provided within the detection frame 40. The replacement component 5 includes a push-pull frame 50. One end of the push-pull frame 50 close to the placement card board 20 is provided with an opening for replacing the connection plug 41. The push-pull frame 50 is slidably arranged inside the detection frame 40 along the length direction of the detection frame 40. A number of limiting strips 51 are symmetrically installed at equal intervals in the height direction on the inner side of the push-pull frame 50. The replaced connection plug 41 is limited by the limiting strips 51, and an installation inner cavity 52 for quickly installing and disassembling the connection plug 41 is formed between the corresponding two limiting strips 51.

[0087] It should be noted that when the connection plug 41 needs to be replaced on the detection frame 40, the connection plug 41 is installed and disassembled through the opening of the push-pull frame 50.

[0088] Furthermore, the different models of connection plugs 41 described in this application refer to connection plugs 41 provided with different numbers of plug-in detection posts 42. In this application, the connection plug 41 with two plug-in detection posts 42 is taken as an example, but there is not only one type of connection plug 41, but also connection plugs 41 of different models.

[0089] When it is necessary to replace the connection plug 41 of a different model, the push-pull frame 50 is pulled out from the side of the detection frame 40 to expose it outside, so as to avoid the detection frame 40 and the installation base 3 from affecting the replacement of the connection plug 41.

[0090] After the push-pull frame 50 is pulled out from the detection frame 40, the connection plug 41 to be replaced is taken out. Then, the new connection plug 41 is aligned with the installation inner cavity 52 formed by the two limiting strips 51, and it is pushed into the push-pull frame 50 from the outside to the inside along the width direction of the push-pull frame 50.

[0091] Refer to Figure 12 、 Figure 13 and Figure 14 As shown, a movable slot 53 is formed on the back side of the connection plug 41. A metal contact 54 is slidably installed in the movable slot 53 along the length direction. An insulating compression spring 55 is connected between the metal contact 54 and the inner wall of the movable slot 53 of the connection plug 41. A metal connecting plate 56 is movably abutted against the slidable metal contact 54 on the connection plug 41. The metal connecting plate 56 is slidably clamped at one end of the push-pull frame 50 away from the placement card board 20, and a return tension spring 57 that has a pulling force on the connection plug 41 is connected between the metal connecting plate 56 and the detection frame 40.

[0092] A linkage conductive plate 58 is also provided on the plug-in detection post 42 of the connection plug 41. One end of the linkage conductive plate 58 away from the plug-in detection post 42 abuts against the bottom of the metal contact 54.

[0093] Look closely Figure 14 As shown, it is a structural diagram of the metal contact 54, and one side of it is a bevel structure.

[0094] After the connection plug 41 is inserted into the inside of the push-pull frame 50, the right-angle limit plate 501 is stretched upward so that one end of the replaced connection plug 41 close to the insertion detection post 42 abuts against the right-angle limit plate 501. Then, the push-pull frame 50 is pushed back into the detection frame 40. At this time, the metal contact 54 squeezes the metal connection plate 56 slidably connected to its back side through the inclined surface until the metal contact 54 abuts against the surface of the metal connection plate 56. At this time, a connected path state is formed among the lighting device 44, the wire 43, the metal connection plate 56, the metal contact 54, and the insertion detection post 42. After the insertion detection post 42 is inserted into the inside of the compound terminal connector, the entire connected path state forms a closed loop to achieve power-on. If the compound terminal connector is qualified in quality, the lighting device 44 lights up; if the compound terminal connector has poor contact or unqualified quality, the lighting device 44 remains in the off state all the time.

[0095] When the connection plug 41 is repeatedly inserted and pulled out of the compound terminal connector, the lighting device 44 will flash on and off.

[0096] A linkage strip-shaped groove 500 is formed at the opening of the push-pull frame 50 and between the corresponding two limit strips 51. A right-angle limit plate 501 is slidably arranged in the linkage strip-shaped groove 500, and one side of the right-angle limit plate 501 is of an inclined surface structure.

[0097] Embodiment 2, on the basis of Embodiment 1, in order to further improve the insertion and extraction durability detection of the compound terminal connector, the present application also proposes a spacing adjuster 6 to detect whether different insertion and extraction depths affect the power-on detection of the compound terminal connector.

[0098] Refer to Figure 15 and Figure 16 As shown, a detection motor 60 is installed at the bottom of the detection platform 2 through a motor seat. The output end of the detection motor 60 is connected upward with a reciprocating wheel 61. The reciprocating wheel 61 is eccentrically connected to the output end of the detection motor 60. One end of the connection plug 41 is provided with a linkage plate 7, and the linkage plate 7 abuts against the reciprocating wheel 61.

[0099] It should be noted that the reciprocating wheel 61 is rotatably arranged on the detection platform 2, and the reciprocating wheel 61 is eccentrically connected to the output end of the detection motor 60. The elastic force of the return spring 57 is much greater than the frictional force of the insertion and extraction of the compound terminal connector.

[0100] After the insertion detection post 42 is inserted into the right-angle through hole 10 of the compound terminal connector, under the action of the pulling force of the return spring 57 without external force extrusion, it automatically resets to the inside of the detection frame 40.

[0101] When it is necessary to detect the insertion and extraction durability of the composite terminal connector, the detection motor 60 is started. The output end of the detection motor 60 drives the reciprocating wheel 61 to rotate. During the rotation of the reciprocating wheel 61, the linkage plate 7 at the bottom of the connection plug 41 is squeezed. Under the action of external force, the linkage plate 7 at the bottom of the connection plug 41 controls the insertion detection posts 42 on a number of connection plugs 41 to insert into the right-angle through holes 10 of the clamped composite terminal connector. And with the cooperation of the return spring 57, the reciprocating movement of the connection plug 41 is realized.

[0102] Further, in order to detect whether different insertion and extraction depths affect the power-on detection of the composite terminal connector while detecting the insertion and extraction durability of the composite terminal connector. The present application also proposes a spacing adjusting member 6, and the spacing adjusting member 6 includes a vertical column 65, an I-shaped slider 66, a fixed block 68, and a displacement screw 69.

[0103] The output end of the detection motor 60 is vertically upward and is connected with a vertical column 65. The top of the vertical column 65 is integrally connected with an I-shaped slider 66. The I-shaped slider 66 is slidably arranged on the reciprocating wheel 61, and a strip-shaped chute 67 for the I-shaped slider 66 to slide is provided on the reciprocating wheel 61.

[0104] A fixed block 68 is also provided on the axis of the reciprocating wheel 61. The displacement screw 69 is rotatably arranged on the reciprocating wheel 61 through a bracket. The displacement screw 69 is rotatably supported on the fixed block 68 through a bearing, and the I-shaped slider 66 is screwed in the middle of the displacement screw 69.

[0105] In the specific implementation process, in addition, the present application can also detect the contact performance of the composite terminal connector. In the initial state, all the insertion detection posts 42 of the connection plug 41 extend out. Therefore, all the insertion detection posts 42 of the connection plug 41 will be inserted into the right-angle through holes 10 of the seat body 1. At this time, the insertion detection posts 42 are all in contact with the metal connectors 11 in the seat body 1. However, in order to detect the contact performance of the metal connectors 11, the depth of the insertion detection posts 42 inserted into the right-angle through holes 10 can be adjusted to detect the power-on conditions when the different insertion detection posts 42 are inserted into the right-angle through holes 10 with different lengths.

[0106] When detecting the composite terminal connector, first, the insertion detection posts 42 can be all inserted into the right-angle through holes 10 of the composite terminal connector and inserted and extracted reciprocally, so as to detect whether it can light up the lighting device 44. If the lighting device 44 lights up, it means that the contact performance is good.

[0107] Subsequently, the connection plug 41 is controlled by the displacement screw 69 so that only three-quarters of the length of the insertion detection posts 42 at its upper end can be inserted into the right-angle through holes 10 of the composite terminal connector. At this time, control it to be inserted and extracted reciprocally. If the lighting device 44 lights up, it means that the contact performance is good; otherwise, the contact performance is poor.

[0108] Next, the connection plug 41 is controlled by the displacement screw 69 so that only two - quarters of the length of the insertion detection post 42 at its upper end can be inserted into the right - angled through - hole 10 of the compound terminal connector. At this time, control it to perform reciprocating plugging and unplugging. If the illuminator 44 lights up, it indicates good contact performance; otherwise, the contact performance is poor.

[0109] Immediately afterwards, the connection plug 41 is controlled by the displacement screw 69 so that only one - quarter of the length of the insertion detection post 42 at its upper end can be inserted into the right - angled through - hole 10 of the compound terminal connector. At this time, control it to perform reciprocating plugging and unplugging. If the illuminator 44 lights up, it indicates good contact performance; otherwise, the contact performance is poor.

[0110] After performing multiple detections on the compound terminal connector, record the detection results, and then judge the performance of the compound terminal connector according to the specified standards.

[0111] During operation: In the first step, when preparing to detect the compound terminal connector, pull the horizontal sliding frame 31 outwards so that the horizontal sliding frame 31 is away from the detection platform 2. Then rotate the adjusting screw 34. By controlling the adjusting screw 34, adjust the position of the strip - shaped clamping plate 32 in the horizontal sliding frame 31 so that the distance between the strip - shaped clamping plates 32 is equal to the width of the seat body 1 of the compound terminal connector. At this time, the seat body 1 can be slidably installed on the inclined chamfer 33 of the strip - shaped clamping plate 32 to limit the seat body 1 of the compound terminal connector.

[0112] In the second step: After the compound terminal connector is clamped, perform the plug - in and unplug - out durability test of the compound terminal connector. The connection plug 41 will reciprocally move towards the compound terminal connector along the width direction of the detection frame 40 and make reciprocal connections and separations with the terminals, metal connectors 11, and extended metal plates 12 inside it. As the insertion detection post 42 performs reciprocating plugging and unplugging, the illuminator 44 on the detection platform 2 will also perform intermittent lighting and turning off operations, and thus the performance of the compound terminal connector can be detected.

[0113] In the third step: When testing compound terminal connectors of different models, pull out the push - pull frame 50 from the side of the detection frame 40, take out the connection plug 41 that needs to be replaced. Then align the new connection plug 41 with the installation cavity 52 formed by the two limit strips 51 and push it into the push - pull frame 50 from the outside to the inside along the width direction of the push - pull frame 50. Then stretch the right - angled limit plate 501 upwards so that the end of the replaced connection plug 41 close to the insertion detection post 42 abuts against the right - angled limit plate 501. Then push the push - pull frame 50 back into the detection frame 40.

[0114] Fourth step: Subsequently, repeat the content in step two to detect the composite terminal connector. If the composite terminal connector is qualified in quality, the illuminator 44 will light up; if the composite terminal connector has poor contact or is unqualified in quality, the illuminator 44 will always be in an off state.

[0115] Fifth step: Further, detect the contact performance of the composite terminal connector, control the depth of the insertion detection post 42 of the connection plug-in 41 inserted into the right-angle through hole 10, and detect the power-on situation when the insertion detection post 42 is inserted into the right-angle through hole 10 at different depths, so as to realize the detection of the elastic performance of the metal connecting piece 11 in the composite terminal connector, detect its wrapping property and deformation ability, and ensure that the overall power-on performance can be guaranteed even when the externally inserted electronic component is not installed in place.

[0116] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
