Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a testing fixture for assembling male connector terminals. Background Technology

[0002] For the electronic equipment manufacturing industry, connectors are key components for achieving circuit connections and signal transmission, and their quality directly affects the stability and reliability of the entire electronic system. Among these, the male connector terminal is a crucial part of the connector, and its installation accuracy, especially the positional precision of the male terminal, has a vital impact on the connector's performance.

[0003] In actual production, due to various factors such as manufacturing processes and assembly operations, the male terminals of connectors often become misaligned. When a connector with misaligned male terminals is connected to other devices, it can easily lead to poor contact, unstable signal transmission, data loss, signal interference, and other problems, thus affecting the normal operation of the entire electronic device. If the misalignment of the male terminals is too severe, the connector may even damage the interface of the connected device during insertion.

[0004] Currently, the detection of misaligned male terminals in connectors mainly relies on manual inspection. Manual inspection is not only time-consuming and labor-intensive, but also extremely inefficient. During long hours and high-intensity inspections, inspectors are prone to visual fatigue, making it difficult to guarantee the accuracy and consistency of the inspections, and thus failing to effectively eliminate connectors with misaligned male terminals. Utility Model Content

[0005] The purpose of this invention is to provide a connector male terminal assembly inspection fixture that can quickly and accurately detect misaligned male terminals, thereby improving inspection efficiency.

[0006] To achieve the above objectives, the solution of this utility model is: a connector male terminal assembly testing fixture, including a base, a probe, and a metal sensing element; The base has slots for connector insertion and several probe through holes, with probes fixedly installed in the probe through holes; The metal sensor is installed in the slot. The metal sensor has several sensing through holes that communicate with the probe through holes. The axial direction of the sensing through holes is consistent with the axial direction of the probe through holes. The position of the sensing through holes corresponds to the position of the male terminal of the connector, so that the male terminal of the connector can pass through the sensing through holes and make electrical contact with the probe to generate a first detection signal, or the male terminal of the connector can make electrical contact with the metal sensor to generate a second detection signal. Both the probe and the metal sensor are electrically connected to the detection equipment.

[0007] In a preferred embodiment, a socket protrudes from the slot, the probe through-hole extends through the socket, and the metal sensor is in the shape of a shell and is fitted onto the socket.

[0008] 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 rotatably mounted on the base. One end of the positioning swing arm is located above the slot, and the middle of the positioning swing arm is provided with a support arm facing the slot. The support arm is used to support the connector, and the output end of the positioning cylinder is used to drive one end of the positioning swing arm to rotate and abut against the connector in the slot.

[0009] In a preferred embodiment, a compression spring is also included, which is disposed on the base and abuts against the other end of the positioning swing arm, the other end of which is located between the compression spring and the positioning cylinder.

[0010] In a preferred embodiment, a detection optical fiber is also included. The bottom of the slot of the base has an installation through hole, and the detection optical fiber is placed in the installation through hole. The position of the detection optical fiber corresponds to the position of the bottom of the connector. The detection optical fiber and the positioning cylinder are electrically connected to the detection equipment.

[0011] After adopting the above solution, the beneficial effects of this utility model are as follows: The base of this invention has a slot for inserting a connector and several probe through holes. The probe is fixedly disposed in the probe through holes and extends into the slot. A metal sensing element is disposed in the slot. The metal sensing element has several sensing through holes communicating with the probe through holes. The axial direction of the sensing through holes is consistent with the axial direction of the probe through holes. The position of the sensing through holes corresponds to the position of the male terminal of the connector. Both the probe and the metal sensing element are electrically connected to the detection equipment. When the male terminal of the connector passes through the sensing through hole and makes electrical contact with the probe, a first detection signal is generated. If the male terminal is skewed, the skewed male terminal first makes electrical contact with the metal sensing element or the hole wall of the sensing through hole to generate a second detection signal. At this time, the detection equipment can determine that the connector has a skewed male terminal based on the first detection signal and the second detection signal. The structure is simple and can quickly and accurately detect the skewed male terminal of the connector, effectively improving the detection efficiency. Attached Figure Description

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] This embodiment provides a connector male terminal assembly testing fixture, such as... Figures 1 to 6 As shown, it includes a base 1, a probe 3, and a metal sensor 4; The base 1 has a slot 10 for inserting the connector 2 and several probe through holes 11, and the probe 3 is fixedly installed in the probe through holes 11; The metal sensor 4 is disposed in the slot 10. The metal sensor 4 has several sensing through holes 40 that communicate with the probe through holes 11. The axial direction of the sensing through holes 40 is consistent with the axial direction of the probe through holes 11. The position of the sensing through holes 40 corresponds to the position of the male terminal 20 of the connector 2, so that the male terminal 20 of the connector 2 can pass through the sensing through holes 40 and make electrical contact with the probe 3 to generate a first detection signal, or the male terminal 20 of the connector 2 can make electrical contact with the metal sensor 4 to generate a second detection signal. The probe 3 and the metal sensor 4 are both electrically connected to the detection equipment.

[0016] In this embodiment, the number of probes 3 corresponds to the number of male terminals 20 of connector 2. To clearly illustrate the structure, only two are shown in the accompanying drawings of this embodiment.

[0017] like Figure 1 , Figure 3 and Figure 5As shown, in this embodiment, the probe through-hole 11 extends to the bottom of the base 1, facilitating the installation of the probe 3. The slot 10 is arranged longitudinally, and correspondingly, the axial direction of the probe through-hole 11 and the sensing through-hole 40 is vertical.

[0018] Specifically, when connector 2 is inserted into slot 10, if the male terminal 20 of connector 2 is in a normal state, it will directly pass through the sensing through-hole 40 and make electrical contact with probe 3 to generate a first detection signal, such as... Figures 1 to 4 As shown; If the male terminal 20 of connector 2 is skewed, the skewed male terminal 20 will contact the metal sensing element 4, or first make electrical contact with the wall of the sensing through hole 40, and then make electrical contact with the probe 3, thereby generating a second detection signal, such as... Figure 5 and Figure 6 As shown, the detection device can determine that the connector 2 has a misaligned male terminal 20 based on the first detection signal and the second detection signal.

[0019] In this embodiment, the connector 2 is inserted into the slot 10 of the base 1. Through the electrical contact between the male terminal 20 and the metal sensing element 4, the detection device can quickly acquire the signal and determine whether the male terminal 20 is misaligned. This greatly shortens the detection time of a single connector 2, improves the overall detection efficiency, and ensures the accuracy of subsequent assembly of the connector 2.

[0020] Of course, the slot 10 and sensing through hole 40 in this embodiment should be set according to the size of the male terminal 20. The detection device (not shown in the figure) can be a conventional device such as a host computer for receiving electrical signals, which can be set by those skilled in the art according to their needs.

[0021] like Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, a socket 12 protrudes from the slot 10, the probe through hole 11 extends through the socket 12, and the metal sensor 4 is in the shape of a shell and is sleeved on the socket 12.

[0022] To facilitate the installation of the metal sensor 4, this embodiment provides a socket 12 in the slot 10, and the metal sensor 4 is set in the shape of a shell. During installation, the metal sensor 4 is simply fixedly sleeved on the socket 12. Of course, the metal sensor 4 can also be fastened to the socket 12 using bolts or the like. The structure is simple. Correspondingly, the probe through hole 11 needs to extend and penetrate the socket 12 so that the male terminal 20 can make good electrical contact with the probe 3.

[0023] Of course, when inserting connector 2 into slot 10 of base 1, to avoid damage to male terminal 20 and probe 3 caused by excessive pressure applied by the testing personnel, such as... Figure 1 , Figure 3 and Figure 5 As shown, this embodiment also includes a positioning cylinder 5 and a positioning swing arm 6. The positioning cylinder 5 is fixedly mounted on the base 1, and the positioning swing arm 6 is rotatably mounted on the base 1. One end of the positioning swing arm 6 is located above the slot 10, and the middle part of the positioning swing arm 6 is provided with a support arm 60 facing the slot 10. The support arm 60 is used to support the connector 2, and the output end of the positioning cylinder 5 is used to drive one end of the positioning swing arm 6 to rotate and abut against the connector 2 in the slot 10.

[0024] In this embodiment, the positioning cylinder 5 and the positioning swing arm 6 are configured as two sets, which can improve the stability of positioning. Figure 1 , Figure 3 and Figure 5 As shown, the two positioning arms 6 are generally S-shaped. When the connector 2 is inserted into the slot 10, the bottom of the connector 2 abuts against the support arm 60 of the positioning arm 6. Then, the output end of the positioning cylinder 5 drives one end of the positioning arm 6 to swing and abut against the top of the connector 2, thus driving the connector 2 downward. At this time, the support arm 60 is still in contact with the bottom of the connector 2. Figure 1 As shown, this is to achieve a continuous support effect.

[0025] As connector 2 moves downwards, if the male terminal 20 of connector 2 is in a normal state, it will directly pass through the sensing through-hole 40 and make electrical contact with probe 3 to generate a first detection signal, such as... Figure 3 and Figure 4 As shown; If the male terminal 20 of connector 2 is skewed, the skewed male terminal 20 will contact the metal sensing element 4, or first make electrical contact with the wall of the sensing through hole 40, and then make electrical contact with the probe 3, thereby generating a second detection signal, such as... Figure 5 and Figure 6 As shown, the detection device can determine that the connector 2 has a misaligned male terminal 20 based on the first detection signal and the second detection signal.

[0026] By using the positioning cylinder 5 in conjunction with the positioning swing arm 6, the downward distance of the connector 2 in the slot 10 can be controlled, thus avoiding damage to the male terminal 20 and probe 3.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, this embodiment also includes a compression spring 7, which is disposed on the base 1 and abuts against the other end of the positioning swing arm 6. The other end of the positioning swing arm 6 is located between the compression spring 7 and the positioning cylinder 5.

[0028] In this embodiment, the positioning swing arm 6 is not directly mounted on the positioning cylinder 5, which facilitates later maintenance and allows for adjustment for connectors 2 of different sizes. Specifically, by setting a compression spring 7 at the other end of the positioning swing arm 6, the two positioning swing arms 6 are in a relatively open state by default. When the connector 2 is inserted into the slot 10, the bottom of the connector 2 abuts against the support arm 60 of the positioning swing arm 6. The output end of the positioning cylinder 5 drives one end of the positioning swing arm 6 to swing and abut against the top of the connector 2 through the other end of the positioning swing arm 6, thus driving the connector 2 downward for detection. Whether the two positioning swing arms 6 are in a relatively open state by default or in a relatively closed state during detection, the support arm 60 on the positioning swing arm 6 extends into the slot 10 to provide support and ensure the smooth progress of the detection process.

[0029] like Figure 1 , Figure 3 and Figure 5 As shown, this embodiment also includes a detection optical fiber 8. The bottom of the slot 10 of the base 1 has an installation through hole 13. The detection optical fiber 8 is disposed in the installation through hole 13. The position of the detection optical fiber 8 corresponds to the position of the bottom of the connector 2. The detection optical fiber 8 and the positioning cylinder 5 are electrically connected to the detection equipment.

[0030] In this embodiment, the detection fiber optic cable 8 and the positioning cylinder 5 are electrically connected to the detection equipment. By setting the detection fiber optic cable 8, when the connector 2 is inserted into the slot 10, the detection fiber optic cable 8 detects the presence of the connector 2. Then, the detection equipment drives the positioning cylinder 5 to work. The output end of the positioning cylinder 5 drives one end of the positioning swing arm 6 to rotate and abut against the top of the connector 2, causing the connector 2 to move downwards for detection. After the detection is completed, the detection equipment drives the output end of the positioning cylinder 5 downwards to release the abutment against the other end of the positioning swing arm 6. Then, the compression spring 7 moves downwards to reset, causing one end of the positioning swing arm 6 to rotate, so that the two positioning swing arms 6 are relatively open. The operator can then remove the connector 2 from the slot 10. At this time, the detection fiber optic cable 8 does not detect the presence of the connector 2, and the positioning cylinder 5 does not move, facilitating the insertion of the next connector 2 into the slot 10. The structure is simple and the control is convenient.

[0031] 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.

[0032] 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.
