Technical Field
[0001] This utility model relates to the field of testing fixture technology, and in particular to a connector female terminal clamping force testing fixture. Background Technology
[0002] As a key component for achieving electrical connections, the stability and reliability of connectors directly affect the normal operation of the entire electronic system. The female connector terminal, as an important part of the connector, has a crucial parameter for ensuring a good electrical connection: the clamping force of its internal tongues on the male terminal. If the clamping force of the female terminal's internal tongues is too small, it will lead to poor contact between the male and female terminals, resulting in signal transmission interruptions, unstable current, and other problems, seriously affecting the performance and lifespan of electronic equipment.
[0003] Currently, there are many limitations in the industry's methods for testing the clamping force of connector female terminals. Traditional testing methods mostly rely on manual operation, applying a certain external force to the female terminal using simple mechanical tools and observing the deformation of the tongue to roughly determine whether the clamping force is up to standard. This method is not only inefficient, but the test results are also greatly affected by the operator's subjective factors, lacking accuracy and consistency, and making it difficult to meet the high precision and high efficiency requirements of product quality testing in large-scale industrial production. Utility Model Content
[0004] The purpose of this utility model is to provide a connector female terminal clamping force testing fixture, which can quickly and accurately detect whether the clamping force of the internal tongue of the connector female terminal is qualified, thereby improving the testing efficiency.
[0005] To achieve the above objectives, the solution of this utility model is: a connector female terminal clamping force detection fixture, including a base, a conductive plate, a plurality of detection probes and a plurality of reset probes; The base has a slot for connector insertion, a first probe through hole and a second probe through hole. The conductive plate is slidably disposed in the slot. The first probe through hole penetrates the conductive plate. The detection probe and the reset probe are respectively disposed in the first probe through hole and the second probe through hole. The position of the detection probe corresponds to the position of the female terminal of the connector. The top of the detection probe passes through the conductive plate and extends into the slot. The top of the reset probe is fixedly connected to the conductive plate. The detection probe has a detection flange that protrudes radially below the conductive plate. Both the detection probe and the reset probe have elastic elements at their bottoms. The elastic elements are used to push the detection flange against the conductive plate to form electrical contact and drive the conductive plate to rise. Both the detection probe and the reset probe are electrically connected to the detection equipment.
[0006] In a preferred embodiment, the device further includes a positioning cylinder and a positioning swing arm. The positioning cylinder is fixedly mounted on the base, and the positioning swing arm is swung on the base. The positioning swing arm is located above the slot, and the output end of the positioning cylinder is used to drive the positioning swing arm to swing and abut against the connector.
[0007] In a preferred embodiment, a starting probe is also included. The base has a third probe through-hole that penetrates the conductive plate. The starting probe is disposed in the third probe through-hole. The starting probe and the positioning cylinder are electrically connected to the detection equipment, respectively.
[0008] In a preferred embodiment, the device further includes a needle sleeve, wherein the elastic element is a compression spring. The needle sleeve is fixedly disposed in the first probe through hole, the second probe through hole, and the third probe through hole, respectively. The detection probe, the reset probe, the start probe, and the compression spring are inserted into the needle sleeve, and the compression spring is located at the bottom of the detection probe, the reset probe, and the start probe.
[0009] In a preferred embodiment, a guide post is also included. The base has a guide blind hole, the bottom of the guide post is fixedly installed in the guide blind hole, the top of the guide post extends into the slot, and the conductive plate has a clearance guide hole at the position corresponding to the guide post. The conductive plate is slidably sleeved on the guide post through the clearance guide hole.
[0010] After adopting the above solution, the beneficial effects of this utility model are as follows: In this invention, since the position of the detection probe corresponds to the position of the female terminal of the connector, when the connector is inserted into the slot, the internal tongue of the female terminal abuts against the top of the detection probe. If the clamping force of the internal tongue of the female terminal is qualified, the connector moves downward, causing the internal tongue of the female terminal to drive the detection probe downward. At the same time, the connector abuts against the conductive plate, causing the conductive plate and the reset probe to move downward together, so that the detection flange moves downward away from the conductive plate. The detection device receives the first detection signal, which means the detection is qualified. Conversely, if the clamping force of the internal tongue of the female terminal is not qualified, when the connector moves downward, the top of the detection probe will directly pass through the internal tongue of the female terminal. At this time, although the connector abuts against the conductive plate, causing the conductive plate, the reset probe and the detection probe to move downward together, the flange of the detection probe is always in electrical contact with the lower surface of the conductive plate. The detection device receives the second detection signal, which means the detection is unqualified. This invention uses a testing device to receive the signal generated by the electrical contact between the testing probe's testing flange and the conductive plate. This allows for quick and accurate detection of whether the clamping force of the internal tongue of the connector's female terminal is qualified, ensuring the quality of product testing. Furthermore, by setting elastic elements at the bottom of the testing probe and the reset probe, the conductive plate and testing probe can be quickly reset after testing for the next test. The structure is simple and effectively improves testing efficiency. Attached Figure Description

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0014] This embodiment provides a connector female terminal clamping force testing fixture, such as Figures 1 to 5 As shown, it includes a base 1, a conductive plate 2, several detection probes 3 and several reset probes 4; The base 1 has a slot 10 for the connector 100 to be inserted, a first probe through hole 11 and a second probe through hole 12. The conductive plate 2 is slidably disposed in the slot 10. The first probe through hole 11 passes through the conductive plate 2. The detection probe 3 and the reset probe 4 are respectively disposed in the first probe through hole 11 and the second probe through hole 12. The position of the detection probe 3 corresponds to the position of the female terminal 101 of the connector 100. The top of the detection probe 3 passes through the conductive plate 2 and extends into the slot 10. The top of the reset probe 4 is fixedly connected to the conductive plate 2. The detection probe 3 has a detection flange 30 that protrudes radially below the conductive plate 2. Both the detection probe 3 and the reset probe 4 have an elastic element 6 at their bottom. The elastic element 6 is used to push the detection flange 30 against the conductive plate 2 to form an electrical contact and drive the conductive plate 2 to rise. Both the detection probe 3 and the reset probe 4 are electrically connected to the detection equipment.
[0015] The connector 100 in this embodiment has multiple female terminals 101, and each female terminal 101 has a tongue 102 inside for electrical contact when plugged into a male terminal. For clarity, only one female terminal 101 and one detection probe 3 are shown in the accompanying drawings of this embodiment, and only two reset probes 4 are shown. The detection device can be a conventional device such as a host computer for receiving electrical signals, which is not shown in the figures; this can be configured by those skilled in the art according to their needs.
[0016] In this embodiment, the conductive plate 2 is horizontally arranged and can slide up and down in the slot 10, while the first probe through hole 11 and the second probe through hole 12 are vertically opened at the bottom of the slot 10. The first probe through hole 11 and the second probe through hole 12 extend from the bottom of the slot 10 and penetrate the base 1.
[0017] like Figure 1 , Figure 3 and Figure 5 As shown, since both the detection probe 3 and the reset probe 4 have elastic elements 6 at their bottoms, in the default state, the elastic elements 6 will continuously push the detection probe 3 and the reset probe 4 upwards, thereby pushing the detection flange 30 of the detection probe 3 against the lower surface of the conductive plate 2 to form electrical contact. At the same time, the elastic force of the elastic element 6 will also cause the conductive plate 2 to rise. (Refer to...) Figure 5 .
[0018] like Figure 1 and Figure 2 As shown, when the connector 100 is inserted into the slot 10, the internal tongue 102 of the female terminal 101 abuts against the top of the detection probe 3. If the clamping force of the internal tongue 102 of the female terminal 101 is qualified, the connector 100 moves downward, causing the internal tongue 102 of the female terminal 101 to drive the detection probe 3 downward. At the same time, the connector 100 abuts against the conductive plate 2, causing the conductive plate 2 and the reset probe 4 to move downward together, so that the detection flange 30 moves downward away from the conductive plate 2. The detection device receives the first detection signal, which means that the detection is qualified.
[0019] Conversely, such as Figure 3 and Figure 4As shown, if the clamping force of the internal tongue 102 of the female terminal 101 is not qualified, the top of the detection probe 3 will directly pass through the internal tongue 102 of the female terminal 101 when the connector 100 moves downward. At this time, although the connector 100 abuts against the conductive plate 2 so that the conductive plate 2, the reset probe 4 and the detection probe 3 move downward together, the flange of the detection probe 3 is always in electrical contact with the lower surface of the conductive plate 2. The detection equipment receives the second detection signal, which means that the detection is unqualified.
[0020] By receiving the first and second detection signals generated by the electrical contact between the detection flange 30 of the detection probe 3 and the conductive plate 2 through the detection equipment, it is possible to quickly and accurately detect whether the clamping force of the internal tongue 102 of the female terminal 101 of the connector 100 is qualified, thus ensuring the detection quality of the product. Furthermore, by setting the elastic element 6 at the bottom of the detection probe 3 and the reset probe 4, the conductive plate 2 and the detection probe 3 can be quickly reset after the detection is completed for the next detection. The structure is simple and effectively improves the detection efficiency.
[0021] like Figure 1 , Figure 3 and Figure 5 As shown, this embodiment also includes a positioning cylinder 70 and a positioning swing arm 71. The positioning cylinder 70 is fixedly mounted on the base 1, and the positioning swing arm 71 is rotatably mounted on the base 1. The positioning swing arm 71 is located above the slot 10, and the output end of the positioning cylinder 70 is used to drive the positioning swing arm 71 to rotatably and abut against the connector 100.
[0022] This embodiment achieves automated testing by setting a positioning cylinder 70 and a positioning swing arm 71. Simply insert the connector 100 into the slot 10, and the output end of the positioning cylinder 70 will drive the positioning swing arm 71 to swing and abut against the connector 100, thereby driving the connector 100 to move downward for testing. The structure is simple and the operation is convenient.
[0023] Furthermore, by using a positioning cylinder 70 in conjunction with a positioning swing arm 71, the clamping force of the internal tongue 102 of the female terminal 101 can be accurately tested. Specifically, the positioning cylinder 70 and the positioning swing arm 71 are used to control the downward distance of the connector 100, thereby simulating different values of force applied to the connector 100. This causes the internal tongue 102 of the female terminal 101 to contact the detection probe 3 with different forces, thus determining the specific value of the clamping force of the internal tongue 102 of the female terminal 101, and further subdividing the clamping force of the female terminal 101 of the connector 100.
[0024] like Figures 1 to 5 As shown, this embodiment also includes a starting probe 5. The base 1 has a third probe through hole 13, which penetrates the conductive plate 2. The starting probe 5 is disposed in the third probe through hole 13. The starting probe 5 and the positioning cylinder 70 are electrically connected to the detection equipment.
[0025] When connector 100 is inserted into slot 10, its bottom rests against the top of start probe 5. Since start probe 5 and positioning cylinder 70 are electrically connected to the testing equipment, start probe 5 controls positioning cylinder 70 to start running through the testing equipment. This causes the output of positioning cylinder 70 to drive positioning arm 71 to swing and rest against connector 100, thereby moving connector 100 downwards for testing. After testing is completed, the testing equipment controls positioning cylinder 70 to stop running. The output of positioning cylinder 70 drives positioning arm 71 to swing and reset, releasing it from the contact with connector 100. Connector 100 can then be removed from slot 10. At this point, connector 100 no longer rests against start probe 5, and start probe 5 is not triggered, keeping positioning cylinder 70 in a stopped state for the next test. The structure is simple and control is convenient.
[0026] like Figures 1 to 5 As shown, this embodiment also includes a needle sleeve 8, and the elastic element 6 is a compression spring 60. The needle sleeve 8 is fixedly disposed in the first probe through hole 11, the second probe through hole 12 and the third probe through hole 13 respectively. The detection probe 3, the reset probe 4, the start probe 5 and the compression spring 60 are inserted in the needle sleeve 8, and the compression spring 60 is located at the bottom of the detection probe 3, the reset probe 4 and the start probe 5.
[0027] In this embodiment, the elastic element 6 is a compression spring 60. During installation, the compression spring 60 is first inserted into the needle sleeve 8, and then the detection probe 3, reset probe 4 and start probe 5 are installed, so that the compression spring 60 is located at the bottom of the detection probe 3, reset probe 4 and start probe 5. The structure is simple and easy to install and remove.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, when connector 100 is inserted into slot 10, the bottom of connector 100 abuts against the top of start probe 5, and the bottom of connector 100 abuts against the inner tongue 102 of female terminal 101 abuts against the top of detection probe 3. Start probe 5 controls positioning cylinder 70 to start running through detection equipment, so that the output end of positioning cylinder 70 drives positioning swing arm 71 to swing and abut against connector 100 and drive connector 100 to move downward.
[0029] If the clamping force of the internal tongue 102 of the female terminal 101 is qualified, the downward movement of the connector 100 causes the internal tongue 102 of the female terminal 101 to drive the detection probe 3 downward. At the same time, the connector 100 abuts against the conductive plate 2, causing the conductive plate 2, the reset probe 4 and the start probe 5 to move downward together, so that the detection flange 30 moves downward and leaves the conductive plate 2. The detection equipment receives the first detection signal, which means that the detection is qualified.
[0030] Conversely, such as Figure 3 and Figure 4 As shown, if the clamping force of the internal tongue 102 of the female terminal 101 is not qualified, the top of the detection probe 3 will directly pass through the internal tongue 102 of the female terminal 101 when the connector 100 moves downward. At this time, although the connector 100 abuts against the conductive plate 2 so that the conductive plate 2, the reset probe 4, the detection probe 3 and the start probe 5 move downward together, the flange of the detection probe 3 is always in electrical contact with the lower surface of the conductive plate 2. The detection device receives the second detection signal, which means that the detection is unqualified.
[0031] like Figure 1 , Figure 3 and Figure 5 As shown, this embodiment also includes a guide post 9, a base 1 with a guide blind hole 14, the bottom of the guide post 9 is fixedly disposed in the guide blind hole 14, the top of the guide post 9 extends into the slot 10, and the conductive plate 2 has a clearance guide hole 20 at a position corresponding to the guide post 9. The conductive plate 2 is slidably sleeved on the guide post 9 through the clearance guide hole 20.
[0032] In this embodiment, by setting guide posts 9, the sliding process of conductive plate 2 in slot 10 is made more stable, ensuring good contact between conductive plate 2 and detection flange 30 during the detection process, and ensuring the accuracy of detection.
[0033] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
[0034] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
[0035] By controlling the downward distance of the connector, the connector is simulated to contact the detection probe with different forces to determine the amount of clamping force.
