Description

Technical Field

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

[0002] Composite terminal connectors are 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 easy to fall off. This type of connector usually uses high-quality conductive materials and advanced contact design to ensure the stability and safety of current transmission, effectively reduce circuit contact resistance, and improve power utilization.

[0003] The excellent performance of composite terminal connectors is often inseparable from the continuous innovation of their production technology and testing technology.

[0004] For example, a Chinese patent with publication number CN116068323A discloses a metal terminal connector and a connector test assembly, wherein the metal terminal connector includes terminals, pins and positioning plates; a dedicated connector test assembly is required for testing the above-mentioned metal terminal connector, and the connector test assembly includes a workbench, a terminal seat, a transmission part and a test part; the following problems existing in the prior art in the terminal testing process are solved: it only involves the plugging between the terminal and the electronic product, and cannot test the locking force between the terminal and the electronic product, and thus cannot test whether the terminal can be smoothly unplugged after being plugged in actual application, which has limitations; the friction between the lower clamp seat and the terminal is small, so the fixing effect of the terminal is not good, and if the locking force between the terminal and the electronic product is too large, the lower clamp seat is easy to slide against the terminal and the terminal cannot be unplugged, and the terminal is easy to get stuck in the electronic product, thereby affecting the test efficiency.

[0005] However, the above connector test components still have some shortcomings in actual use: 1. First, the above-mentioned terminals are repeatedly plugged in and out of the terminal seat, which is convenient for automatic testing of multiple terminals at one time. However, it can only detect terminals of a single model. If the number of pins of different terminals is inconsistent, it cannot be tested. Furthermore, it cannot detect terminals of different sizes, which leads to a certain degree of uniformity and poor applicability.

[0006] 2. In addition, during the plugging and unplugging process, the plugging and unplugging depth of the terminal always remains the same, and it is impossible to detect whether different plugging and unplugging depths will affect the terminal connector, thereby simulating the situation of improper plugging and unplugging assembly in daily life, and further testing its contact performance to see if it will cause poor contact.

[0043] The following is combined with Figure 1-Figure 16 This application is described in further detail.

[0044] The embodiment of the present application discloses a composite terminal connector and a detection fixture thereof; it relates to a composite terminal connector and a composite terminal connector detection fixture for the composite terminal connector of the above-mentioned model; the composite terminal connector is mainly used in the electronics industry.

[0045] Firstly, multiple terminals are repeatedly plugged in and out at the same time, which is convenient for automatic testing of multiple terminals at one time. However, it can only detect terminals of a single model. If the number of pins of different terminals is inconsistent, it cannot be tested. Furthermore, terminals of different sizes cannot be tested either, which leads to a certain degree of uniformity and poor applicability.

[0046] Secondly, during the process of plugging and unplugging the terminals, the plugging and unplugging depths remain consistent, and it is impossible to detect whether different plugging and unplugging depths will affect the terminal connector. This simulates the situation of improper plugging and unplugging assembly in daily life, and further detects its contact performance to see if it will cause poor contact.

[0047] Therefore, the present application proposes a composite terminal connector and a detection fixture thereof.

[0048] Embodiment 1: See also Figure 1 and Fig.12 As shown, the present application relates to a composite terminal connector, comprising a stationary seat body 1, with right-angle through holes 10 vertically distributed on both sides of the seat body 1, two groups of metal connectors 11 are arranged in the right-angle through holes 10 of the seat body 1, the metal connectors 11 are distributed at right angles, and the metal connectors 11 are provided with integrated extended metal plates 12 extending and bending outward near both ends of the right-angle through holes 10 of the seat body 1, and the extended metal plates 12 abut against the right-angle through holes 10, and both ends of the two metal connectors 11 are integrated with terminals installed in the right-angle through holes 10.

[0049] The seat body 1 in the present application is made of insulating material, which can ensure the stability of the metal connector 11 and the terminal inside it; and adopts high-quality conductive materials and advanced contact design to ensure the stability and safety of current transmission. This design effectively reduces the circuit contact resistance, reduces power consumption, and improves the utilization rate of electric energy.

[0050] Furthermore, the metal connector 11 is in a right-angle shape, and the terminal structures at both ends are the same, which can ensure that the electronic components can be inserted into any position at both ends at will, thereby ensuring the diversity of the connection of the electronic components.

[0051] Furthermore, the base body 1 protects the metal connector 11 and the terminal, so that it can operate stably for a long time in harsh environments and has high drop resistance, thereby extending its service life; then, it can also adapt to different application scenarios, including high temperature, vibration and other environmental conditions, ensuring that it can maintain good performance under various conditions.

[0052] See also Figure 2 and Figure 3As shown, it is a structural schematic diagram of the connection between the metal connector 11 in the seat body 1 and the external electronic components in the present application; a limiting plate 14 is also arranged in the right-angle through hole 10 of the seat body 1, and the limiting plate 14 is slidably arranged in the right-angle through hole 10, and a limiting compression spring 15 is arranged between the end of the limiting plate 14 away from the extended metal plate 12 and the inner wall of the seat body 1, and the end of the limiting plate 14 close to the limiting compression spring 15 is also connected to a right-angle slide plate 16, the right-angle slide plate 16 is slidably arranged in the seat body 1, and one end of the right-angle slide plate 16 slides through the seat body 1 for external force control.

[0053] When a connection operation is required, when inserting the connecting wire of the external electronic component into the right-angled circular 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 limiting plate 14 away from the metal connector 11 and the extended metal plate 12, so that a plug-in area is presented between the metal connector 11 and the limiting plate 14 for plugging in the connecting wire of the external electronic component. Then, after inserting the connecting wire of the electronic component into the plug-in area, release the right-angled slide plate 16, and the limiting compression spring 15 on the back side of the right-angled slide plate 16 squeezes the right-angled slide plate 16 and the limiting plate 14, so that the connecting wire of the electronic component is clamped between the limiting plate 14 and the metal connector 11.

[0054] It should be noted that the limit plate 14 is an insulating structure; and the limit compression spring 15 has a relatively large elastic force; the electronic components are external known structures, and their connecting wires are used for power supply.

[0055] The connection method of the existing composite terminal connector is relatively complicated, and it mainly realizes the connection of the connecting wires of electronic components by deformation of metal parts. The present application realizes clamping of the connecting wires of electronic components by elastic clamping, thereby realizing rapid connection and disassembly of the connecting wires of electronic components. This not only ensures the efficiency of the connection but also maintains the stability of the connection, thereby preventing the connecting wires of electronic components from falling off.

[0056] With respect to the above-mentioned composite terminal connector, the present application also provides a detection fixture specifically for the above-mentioned composite terminal connector.

[0057] See also Figure 4 As shown, the inspection fixture of the composite terminal connector includes a stationary inspection platform 2, on which a vertically distributed placement card plate 20 is integrated, and a mounting base 3 for snap-fitting and installing the base body 1 of the composite terminal connector is slidably provided on one side of the placement card plate 20, and a detector 4 for performing power-on detection on the composite terminal connector arranged on the mounting base 3 is also provided on the inspection platform 2.

[0058] First, the detection platform 2 is set on the ground, and the mounting base 3 arranged on the placement card 20 can slide laterally, and it can install composite terminal connectors of different sizes.

[0059] The detector 4 can perform automated plugging and unplugging tests on composite terminal connectors of different sizes and dimensions, detect the durability of the composite terminal connector, and the stability of the electrical signal during the plugging and unplugging process. It can also detect the contact performance of the metal connector 11 of the composite terminal connector to detect whether it is prone to poor contact.

[0060] Reference Figure 5 , Figure 6 and Figure 7 As shown, the mounting base 3 includes a horizontal guide rail 30 arranged on the card plate 20, and a sliding horizontal slide frame 31 is arranged on the horizontal guide rail 30. The horizontal slide frame 31 has a plurality of strip clamps 32 installed at equal intervals along the length direction for the seat body 1 to be installed, and the strip clamps 32 are provided with chamfers 33.

[0061] The horizontal sliding frame 31 is also rotatably connected with an adjusting screw 34 via a bearing, and the strip clamping plate 32 is symmetrically screwed on the adjusting screw 34 .

[0062] The horizontal guide rail 30 in the present application is arranged on the placement card plate 20, and its purpose is to ensure the horizontal movement of the horizontal slide frame 31. When the composite terminal connector needs to be tested, the horizontal slide frame 31 is stretched outward to make the horizontal slide frame 31 away from the testing platform 2, and then the adjusting screw 34 is rotated to control the position of the strip clamp 32 in the horizontal slide frame 31 through the adjusting screw 34, so that the spacing between the strip clamps 32 is equal to the width of the composite terminal connector seat body 1. At this time, the seat body 1 can be slidably installed on the chamfered corner 33 of the strip clamp 32 to limit the seat body 1 of the composite terminal connector.

[0063] The preparation work before testing the composite terminal connector is to adjust the distance between the two strip clamps 32 when clamping composite terminal connectors of different sizes.

[0064] After the composite terminal connector is clamped, the composite terminal connector is first tested for plugging and unplugging durability, as shown below: Reference Figure 8 As shown, specifically, the detector 4 includes a detection frame 40 distributed parallel to the placement card board 20 on the detection platform 2, and a plurality of connection plug-ins 41 connected to the composite terminal connector are installed at equal intervals in the detection frame 40. The end of the connection plug-in 41 close to the composite terminal connector is provided with a plug-in detection column 42 inserted into the right-angle through hole 10 of the seat body 1, and the back side of the connection plug-in 41 is connected to a wire 43 for power-on detection. The back side of the connection plug-in 41 is also connected to lamps 44 one by one through the wires 43, and the plurality of lamps 44 are integrated on the detection platform 2.

[0065] It should be noted that the connecting plug 41 is a known structure and is conductive, and the plug detection column 42 on the connecting plug 41 is connected to the lighting device 44 through a wire 43 .

[0066] Furthermore, there are two detection frames 40 on the detector 4, and the two detection frames 40 are distributed vertically. The detection frame 40 on the card board 20 is provided with the same structure as the detection frame 40 on the detection platform 2, and different types of connecting plug-ins 41 can be quickly replaced. The plug-in detection column 42 in the detection frame 40 on the card board 20 is also connected to the integrated lighting device 44 on the detection platform 2 through the wire 43.

[0067] The components inside the two detection frames 40 have the same structure and the same function.

[0068] During the specific implementation process, when the plug-in durability test of the composite terminal connector is carried out, the connecting plug-in 41 in the detection frame 40 will move back and forth toward the composite terminal connector along the width direction of the detection frame 40. During the movement, the plug-in detection column 42 of the connecting plug-in 41 will be reciprocatedly inserted into the right-angle through hole 10 in the horizontal direction of the composite terminal connector, and reciprocately connect and separate with the terminal, metal connector 11 and extended metal plate 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.

[0069] Therefore, as the plug-in detection column 42 is reciprocatedly plugged in and out, the lamp 44 on the detection platform 2 will also intermittently light up and turn off the light until the plug-in detection column 42 is plugged in and out a specified number of times. If the lamp 44 can still light up normally, it means that the quality of the tested composite terminal connector is qualified.

[0070] If the lighting device 44 fails to light up, the lighting device 44 is tested. If it is determined that the lighting device 44 is not damaged, it can be determined that the tested composite terminal connector is of poor quality and unqualified.

[0071] When it is necessary to detect the maximum service life of the composite terminal connector, the composite terminal connector is continuously plugged and unplugged until the lamp 44 fails to light up, and then the lamp 44 is tested. When it is determined that the lamp 44 is not damaged, the maximum service life test of the composite terminal connector is completed.

[0072] When conducting plugging and unplugging durability test of composite terminal connectors, multiple groups of composite terminal connectors are tested at the same time to form a control group. Through plugging and unplugging control tests of multiple groups of composite terminal connectors, the plugging and unplugging test data of the composite terminal connectors are compared. Firstly, the accuracy of the plugging and unplugging durability test results of the composite terminal connectors can be greatly improved, and secondly, the randomness of the test results can be avoided.

[0073] Furthermore, when the composite terminal connector is reciprocatingly plugged in and out, the lighting device 44 monitors and records the intensity of the current and voltage during the detection process in real time.

[0074] See also Fig. 9 As shown, it is a structural schematic diagram of the plug-in and pull-out test of the composite terminal connector on the detection platform 2 in this application; a detection motor 60 is slidably installed on the bottom of the detection platform 2 through a motor seat, and a reciprocating wheel 61 is also connected to the detection platform 2, and the reciprocating wheel 61 is eccentrically connected to the output end of the detection motor 60.

[0075] A linkage plate 7 is disposed at one end of the connecting plug 41 , and the linkage plate 7 abuts against the reciprocating wheel 61 .

[0076] A horizontal linkage rack 62 is installed on the connecting plug-in 41. The end of the horizontal linkage rack 62 away from the connecting plug-in 41 is meshed with a linkage gear 63 rotating on the detection platform 2. The linkage gear 63 is also vertically meshed with a vertical linkage rack 64. The vertical linkage rack 64 is connected to the detection frame 40 sliding on the card plate 20.

[0077] During the specific implementation process, the detection motor 60 is started, and the detection motor 60 controls the reciprocating wheel 61 to rotate. The reciprocating wheel 61 squeezes the connecting plug 41 while rotating, and with the cooperation of the reset spring 57, it continuously performs reciprocating operations on the composite terminal connector for plugging and unplugging, thereby realizing power-on detection. Further, it can also realize durability detection of the composite terminal connector during the plugging and unplugging process.

[0078] When testing different models of composite terminal connectors, it is necessary to replace the corresponding connecting plug-in 41. This application takes a two-hole composite terminal connector as an example. If a composite terminal connector with multiple right-angle through holes 10 appears, it is necessary to replace the component 5 for quick replacement to improve efficiency.

[0079] Therefore, the present application proposes a replacement component 5, which can test different types of composite terminal connectors, and can also quickly disassemble and replace the corresponding connecting plug-in 41 according to different types of composite terminal connectors, so as to test different types of composite terminal connectors, which can greatly improve the applicability of the fixture.

[0080] The details are as follows: See also Fig.10 and Fig.11As shown, a replacement component 5 for facilitating replacement of connection plug-ins 41 of different types is also provided in the detection frame 40, and the replacement component 5 includes a push-pull frame 50. An opening for replacing the connection plug-in 41 is provided at one end of the push-pull frame 50 close to the card plate 20. The push-pull frame 50 is slidably arranged inside the detection frame 40 along the length direction of the detection frame 40. A plurality of limit bars 51 are symmetrically installed at equal intervals in the height direction of the inner side of the push-pull frame 50. The replaced connection plug-in 41 is limited by the limit bars 51, and an installation cavity 52 for quick installation and removal of the connection plug-in 41 is formed between the corresponding two limit bars 51.

[0081] It should be noted that when the connection plug-in 41 on the detection frame 40 needs to be replaced, the connection plug-in 41 is installed and removed from the opening of the push-pull frame 50 .

[0082] Furthermore, the different models of connecting plug-ins 41 described in this application refer to connecting plug-ins 41 with different numbers of plug-in detection columns 42. In this application, a connecting plug-in 41 with two plug-in detection columns 42 is taken as an example, but there is not only one type of connecting plug-in 41, but also different models of connecting plug-ins 41.

[0083] When a different type of connection plug-in 41 needs to be replaced, the push-pull frame 50 is pulled out from the side of the detection frame 40 to expose it to the outside, so as to prevent the detection frame 40 and the mounting base 3 from affecting the replacement of the connection plug-in 41.

[0084] When the push-pull frame 50 is pulled out of the detection frame 40 , the connection plug-in 41 to be replaced is taken out, and then the new connection plug-in 41 is aligned with the installation cavity 52 formed by the two limit strips 51 and pushed into the push-pull frame 50 from the outside to the inside along the width direction of the push-pull frame 50 .

[0085] See also Fig.12 , Fig.13 and Fig.14 As shown, a movable groove 53 is provided on the back side of the connecting plug 41, and a metal contact block 54 is slidably installed in the movable groove 53 along the length direction, and an insulating compression spring 55 is connected between the metal contact block 54 and the inner wall of the movable groove 53 of the connecting plug 41, and a metal connecting plate 56 is movably abutted against the metal contact block 54 slidably arranged on the connecting plug 41, and the metal connecting plate 56 is slidably clamped on the end of the push-pull frame 50 away from the placement of the card plate 20, and a reset tension spring 57 with a pulling force on the connecting plug 41 is connected between the metal connecting plate 56 and the detection frame 40.

[0086] A linkage conductive plate 58 is further provided on the plug detection post 42 of the connecting plug 41 , and one end of the linkage conductive plate 58 away from the plug detection post 42 abuts against the bottom of the metal contact block 54 .

[0087] A closer look Fig.14 As shown, it is a structural diagram of the metal contact block 54, one side of which is a sloped structure.

[0088] After the connecting plug 41 is inserted into the interior of the push-pull frame 50, the right-angle limit plate 501 is stretched upward so that the end of the replaced connecting plug 41 close to the plug-in detection column 42 rests on the right-angle limit plate 501, and then the push-pull frame 50 is pushed back into the detection frame 40. At this time, the metal contact 54 squeezes the metal connecting plate 56 that is slidably connected to its back side through the inclined surface until the metal contact 54 abuts against the surface of the metal connecting plate 56. At this time, a connected path state will be formed among the lamp 44, the wire 43, the metal connecting plate 56, the metal contact 54 and the plug-in detection column 42. After the plug-in detection column 42 is inserted into the interior of the composite terminal connector, the entire connected path state will form a closed loop to achieve power-on. If the composite terminal connector is of qualified quality, the lamp 44 will light up; if the composite terminal connector has poor contact or unqualified quality, the lamp 44 will always be in an off state.

[0089] When the connecting plug 41 is reciprocatedly plugged into and pulled out of the composite terminal connector, the lighting device 44 will flash on and off.

[0090] A linkage strip groove 500 is provided at the opening of the push-pull frame 50 and between the two corresponding limit strips 51 . A right-angle limit plate 501 is slidably provided in the linkage strip groove 500 , and one side of the right-angle limit plate 501 is a slope structure.

[0091] Embodiment 2, based on embodiment 1, in order to further improve the plugging and unplugging durability test of the composite terminal connector, the present application further proposes a spacing adjustment member 6 to detect whether different plugging and unplugging depths affect the power-on test of the composite terminal connector.

[0092] See also Fig.15 and Fig.16 As shown, a detection motor 60 is installed at the bottom of the detection platform 2 through a motor seat, and the output end of the detection motor 60 is upwardly connected to a reciprocating wheel 61, and the reciprocating wheel 61 is eccentrically connected to the output end of the detection motor 60, and a linkage plate 7 is provided at one end of the connecting plug-in 41, and the linkage plate 7 rests on the reciprocating wheel 61.

[0093] 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, and the elastic force of the reset spring 57 is much greater than the friction force of the composite terminal connector during plugging and unplugging.

[0094] When the plug detection post 42 is inserted into the right-angle through hole 10 of the composite terminal connector, it automatically returns to the inside of the detection frame 40 due to the tension of the return spring 57 when the external force is no longer pressing.

[0095] When it is necessary to test the plug-in durability of the composite terminal connector, start the detection motor 60, and 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 connecting plug-in 41 is squeezed. Under the action of external force, the linkage plate 7 at the bottom of the connecting plug-in 41 controls the plug-in detection columns 42 on the connecting plug-ins 41 to be inserted into the right-angle through hole 10 of the clamped composite terminal connector, and accompanied by the cooperation of the reset tension spring 57, the reciprocating movement of the connecting plug-in 41 is realized.

[0096] Furthermore, in order to detect the plugging and unplugging durability of the composite terminal connector and whether different plugging and unplugging depths affect the power-on detection of the composite terminal connector, the present application also proposes a spacing adjustment member 6, which includes a vertical column 65, an I-shaped slider 66, a fixing block 68 and a displacement screw 69.

[0097] The output end of the detection motor 60 is vertically upward and connected to a vertical column 65. The top of the vertical column 65 is integrally connected to an I-shaped slider 66. The I-shaped slider 66 is slidably arranged on the reciprocating wheel 61, and a strip-shaped slide groove 67 is provided on the reciprocating wheel 61 for the I-shaped slider 66 to slide.

[0098] A fixed block 68 is also provided on the axis of the reciprocating wheel 61 . A displacement screw 69 is rotatably provided on the reciprocating wheel 61 through a bracket. The displacement screw 69 rotates on the fixed block 68 through a bearing, and an I-shaped slider 66 is screwed to the middle of the displacement screw 69 .

[0099] During the specific implementation process, in addition, the present application can also detect the contact performance of the composite terminal connector. In the initial state, the plug-in detection column 42 of the connecting plug-in 41 is fully extended, so the plug-in detection column 42 of the connecting plug-in 41 will be fully inserted into the right-angle through hole 10 of the seat body 1. At this time, the plug-in detection column 42 is fully in contact with the metal connector 11 in the seat body 1. However, in order to detect the contact performance of the metal connector 11, the depth of the plug-in detection column 42 inserted into the right-angle through hole 10 can be adjusted to detect the power-on status when different plug-in detection columns 42 are inserted into the right-angle through hole 10 at different lengths.

[0100] When testing the composite terminal connector, first the plug-in test column 42 can be fully inserted into the right-angle through hole 10 of the composite terminal connector, and then reciprocated plugging and unplugging are performed to test whether the luminaire 44 can be lit. If the luminaire 44 is lit, it means that the contact performance is good.

[0101] Then, the connecting plug 41 is controlled by the displacement screw 69 so that only three-quarters of the length of the plug detection column 42 at its upper end can be inserted into the right-angle through hole 10 of the composite terminal connector. At this time, it is controlled to perform reciprocating plugging and unplugging. If the light 44 is on, it means that the contact performance is good; otherwise, the contact performance is poor.

[0102] Then, the connecting plug 41 is controlled by the displacement screw 69 so that only two-quarters of the length of the plug detection column 42 at its upper end can be inserted into the right-angle through hole 10 of the composite terminal connector. At this time, it is controlled to perform reciprocating plugging and unplugging. If the light 44 is on, it means that the contact performance is good; otherwise, the contact performance is poor.

[0103] Thereafter, the connecting plug 41 is controlled by the shifting screw 69 so that only one quarter of the length of the plug detection column 42 at its upper end can be inserted into the right-angle through hole 10 of the composite terminal connector. At this time, it is controlled to perform reciprocating plugging and unplugging. If the light 44 is on, it indicates that the contact performance is good; otherwise, the contact performance is poor.

[0104] After the composite terminal connector is tested multiple times, the test results are recorded so as to judge the performance of the composite terminal connector according to the specified standards.

[0105] During operation: The first step is to stretch the horizontal slide frame 31 outward when preparing to inspect the composite terminal connector so that the horizontal slide frame 31 is away from the inspection platform 2, and then the adjusting screw 34 is turned to control the position of the strip clamp 32 in the horizontal slide frame 31 through the adjusting screw 34, so that the spacing between the strip clamps 32 is equal to the width of the composite terminal connector seat 1. At this time, the seat 1 can be slidably installed on the chamfered corner 33 of the strip clamp 32 to limit the seat 1 of the composite terminal connector.

[0106] Step 2: After the composite terminal connector is clamped, the plug-in durability test of the composite terminal connector is carried out. The connecting plug 41 will move back and forth along the width direction of the detection frame 40 toward the composite terminal connector, and reciprocately connect and separate with the internal terminals, metal connectors 11 and extended metal plates 12. As the plug-in detection column 42 is reciprocatedly plugged in and out, the lighting device 44 on the detection platform 2 will also intermittently light up and turn off the light, thereby testing the performance of the composite terminal connector.

[0107] Step 3: When testing different types of composite terminal connectors, pull the push-pull frame 50 out from the side of the detection frame 40, take out the connection plug-in 41 that needs to be replaced, then align the new connection plug-in 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-angle limit plate 501 upward so that the end of the replaced connection plug-in 41 close to the plug-in detection column 42 rests on the right-angle limit plate 501, and then push the push-pull frame 50 back into the detection frame 40.

[0108] Step 4: Repeat the steps in step 2 to test the composite terminal connector. If the composite terminal connector is of qualified quality, the light 44 will light up. If the composite terminal connector has poor contact or unqualified quality, the light 44 will remain off.

[0109] Step 5: Further, detect the contact performance of the composite terminal connector, control the depth of the plug-in detection column 42 of the connecting plug 41 inserted into the right-angle through hole 10, and detect the power-on status when the plug-in detection column 42 is inserted into the right-angle through hole 10 at different depths, thereby realizing the detection of the elastic performance of the metal connector 11 in the composite terminal connector, detecting its wrapping and deformation capabilities, and ensuring that the externally inserted electronic components can guarantee the overall power-on performance even when they are not installed in place.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
