Description

Technical Field

[0001] The present invention relates to the technical field of connector manufacturing, and particularly to a high-precision connector pin positioning device. Background Art

[0002] In many fields such as electronic devices, connectors play a crucial role. They can achieve reliable electrical connections between different electronic components. As key conductive components in the connectors, the accurate positioning of the pins has a decisive impact on ensuring the performance and quality of the connectors.

[0003] Referring to the patent of CN202310663473.9, the present invention provides a high-precision pin tensile force detection device, including an equipment base. A positioning frame assembly, a sliding plate assembly, and a traction frame assembly are respectively installed on the upper surface of the equipment base. A clamping clip assembly is installed on one side of the sliding plate assembly, and one side of the traction frame assembly is installed on the other side of the sliding plate assembly. The positioning frame assembly includes a positioning frame body, an upper locator, and a lower locator. The upper surface of the positioning frame body is threadedly connected to the upper surface of the equipment base through bolts. An installation hole is provided on one side of the positioning frame body. The mutually repulsive sides of the upper locator and the lower locator are attached to the installation hole of the positioning frame body. A butterfly top screw is threadedly connected to the upper surface of the positioning frame body. The present invention solves the problems of poor positioning and coaxiality of the pin specimens in the original test device, improves the detection accuracy value after the pin specimens are crimped with the cable, and truly reflects the actual tensile strength value after the pins of the electrical connector are crimped with the cable.

[0004] Based on the retrieval of the above patent and combined with the current connector pin positioning methods, it is found that there are still the following deficiencies in the use of connector pins: Firstly, when traditional connector pins are connected to the main body, they often rely only on simple plug-and-play cooperation or conventional fixing structures, lacking an effective anti-detachment mechanism. When the equipment faces working conditions such as vibration and impact, the pins are likely to loosen or even fall out from the jacks of the connector main body.

[0005] Secondly, when multiple connectors are docked and assembled, the existing connection structures usually have difficulty ensuring long-term stability after connection, affecting the overall structural integrity of the electronic device and the coherence of signal transmission.

[0006] Thirdly, many connector main bodies are provided with slot hole structures for installation, fixing, or connecting circuits, etc., but there is a lack of effective protection design for these parts. Dust, foreign objects, etc. are likely to enter them, which may not only affect the normal use of the internal components but also may cause failures such as short circuits due to accumulation. Summary of the Invention

[0007] In view of this, the present invention provides a high-precision connector pin positioning device. The elastic clamping plate can be clamped into the locking groove on the inner end face of the locking tube. Under the oscillating working conditions of the connector body, the elastic clamping plate plays a role, which can effectively limit the axial movement of the fixed pin in the jack, prevent it from easily falling out of the jack, and ensure the reliability of the connection between the fixed pin and the connector body. When the clamping block is clamped inside the transverse clamping groove, the limiting holes on the surface of the clamping block are aligned with the device holes, and the limiting clamping column at the front end of the sliding plate will be clamped into the limiting holes under the elastic force of the connecting spring, further restricting the movement of the clamping block in the transverse clamping groove, and effectively ensuring the stability of the two components after connection.

[0008] The present invention provides the purpose and efficacy of a high-precision connector pin positioning device, which specifically includes: a connector body; The front surface of the connector body is provided with a jack, the left surface of the connector body is provided with a transverse clamping groove, two device holes are provided at the bottom end surface of the transverse clamping groove, a first connection groove is provided at the rear position of the upper surface of the connector body, and a contact member is installed on the upper surface of the connector body; A locking tube, a circular ring-shaped baffle is installed at the front position of the outer end surface of the locking tube, and the locking tube is located in the jack at the front end of the connector body; A fixed pin, the plugging end of the fixed pin is in a frustum shape, and the plugging end of the fixed pin is clamped in the locking tube.

[0009] Furthermore, a clamping block is installed on the right end surface of the connector body. The clamping block has the same structure as the transverse clamping groove, and two limiting holes are provided on the surface of the clamping block.

[0010] Furthermore, when the clamping block is clamped inside the transverse clamping groove, the limiting holes on the surface of the clamping block are aligned with the device holes.

[0011] Furthermore, a limiting member is slidably installed in the device hole. A connecting spring is installed between the rear end surface of the limiting member and the bottom wall of the device hole. A limiting clamping column extending out of the device hole is installed on the front end surface of the limiting member, and the outer diameter of the limiting clamping column is the same as the inner diameter of the limiting hole.

[0012] Furthermore, an installation hole is provided at the bottom end surface of the first connection groove, and a movable cover plate is rotatably connected to the upper end surface of the first connection groove. When the movable cover plate is in a closed state, the outer end surface of the movable cover plate is flush with the outer end surface of the connector body.

[0013] Furthermore, a notch is provided at the front end surface of the jack, threads are provided on the inner end surface of the notch, and the locking tube is threadedly connected inside the notch.

[0014] Further, a locking groove is provided on the inner end surface of the locking tube. A plurality of second connection grooves are evenly formed on the outer circumference of the fixed pin. Elastic clamping plates are installed inside the second connection grooves. The front end surface of the elastic clamping plate is of an inclined structure, and the rear end part of the elastic clamping plate is in a suspended state. When the front end of the fixed pin is located inside the jack, the elastic clamping plate is located in the locking groove on the inner end surface of the locking tube.

[0015] The present invention provides a high-precision connector pin positioning device, and its beneficial effects are as follows: 1. It can effectively prevent the fixed pin from falling out of the jack. A plurality of groups of second connection grooves are annularly formed on the outer end surface of the fixed pin, and elastic clamping plates are installed inside the second connection grooves. At the same time, a locking groove is provided on the inner end surface of the locking tube. When the front end of the fixed pin is located inside the jack, the elastic clamping plate can be snapped into the locking groove on the inner end surface of the locking tube. Under the condition that the connector body is in an oscillating working state, the elastic clamping plate plays a role, which can effectively limit the axial movement of the fixed pin in the jack and prevent it from easily falling out of the jack, ensuring the reliability of the connection between the fixed pin and the connector body.

[0016] 2. It is convenient for the pin to be inserted. The front end surface of the elastic clamping plate is of an inclined structure. During the process of inserting the fixed pin into the jack, it will be squeezed along the inner wall of the jack, causing the elastic clamping plate to contract into the second connection groove until the front end of the fixed pin completely enters the jack. This structural design facilitates the smooth insertion of the fixed pin into the jack and improves the convenience of the assembly operation.

[0017] 3. A clamping block is installed on the right end surface of the connector body, and its structure is the same as that of the transverse card slot. When two connector bodies are docked, the clamping block can be snapped into the transverse card slot on the surface of another connector body to achieve preliminary alignment and connection. Moreover, when the clamping block is snapped into the transverse card slot, the limiting hole on the surface of the clamping block is aligned with the device hole, and the limiting clamping column at the front end of the limiting member will be snapped into the limiting hole under the elastic force of the connecting spring, further restricting the movement of the clamping block in the transverse card slot, effectively ensuring the stability after the connection of the two components, preventing accidental loosening or detachment, and improving the firmness of the overall structural connection.

[0018] 4. A movable cover plate is rotatably connected to the upper end surface of the first connection groove. When the movable cover plate is in a closed state, its outer end surface is flush with the outer end surface of the connector body. It can protect the components such as screws inside the first connection groove, effectively prevent dust, foreign objects, etc. from entering, avoid affecting the normal use of the internal components or causing damage due to these external factors, and contribute to extending the service life of the internal components of the device and maintaining its performance stability.
