Description

Technical Field

[0001] This utility model relates to the field of connector terminal technology, specifically a connector terminal with multiple contact points. Background Technology

[0002] Existing terminals mostly adopt an integrated structure, in which the wires are directly fixed to the terminals, making assembly and effective disassembly impossible. When equipment requires multiple contact points, the entire connector terminal must be replaced with a suitable one, thus increasing the equipment modification cost. Therefore, those skilled in the art have provided a connector terminal with multiple contact points to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a connector terminal with multiple contact points to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A connector terminal with multiple contact points includes a receiving plate, a plug is fixedly connected to the surface of the receiving plate, a mounting groove is provided in the receiving plate, a plug slot is provided in the receiving plate and the plug slot and the mounting groove are interconnected, a fixing component is provided in the plug slot and the mounting groove, and an output wire is installed in the plug slot and the mounting groove through the fixing component.

[0005] Furthermore, the fixing component includes terminal pins and anti-detachment plates. Terminal pins are slidably connected inside the connector, and anti-detachment plates are fixedly connected to both sides of the terminal pins. Both the terminal pins and the anti-detachment plates are placed in the connector groove, and the surface of the anti-detachment plates is in close contact with the inner sidewall of the connector groove.

[0006] Furthermore, the fixing assembly also includes a conductive plate and a positioning plate. The conductive plate is fixedly connected to the upper and lower ends of the terminal pin, and the positioning plate is fixedly connected to both sides of the conductive plate. One end of the positioning plate is inserted into the insertion slot, and the other end of the positioning plate is placed in the mounting slot. The positioning plate is L-shaped as a whole.

[0007] Furthermore, the fixing assembly also includes a shunt port sleeve and a main port sleeve, with the shunt port sleeve fixedly connected to one end of the positioning plate and the main port sleeve fixedly connected to one end of the shunt port sleeve.

[0008] Furthermore, the fixing component also includes a fixing sleeve and an output wire. The output wire is sleeved inside the main bundle sleeve, and the output wire is a multi-strand wire. The shunt bundle sleeve is also sleeved on the surface of the sub-strands of the output wire, and the fixing sleeve is fixedly connected to the surface of the output wire.

[0009] Furthermore, a connecting plate is fixedly connected to the upper end of the receiving plate, and a snap-fit ​​plate is fixedly connected to the upper end of the connecting plate.

[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. Through the integrated structure of "receiving plate + connector", an installation groove is opened in the receiving plate and a connecting groove is set through the connector and the receiving plate, forming a continuous space of "external docking - internal installation". By preset the width of the receiving plate, the width of the receiving plate can be flexibly increased or decreased according to the actual number of contact points required, thereby increasing or decreasing the number of connectors. When more contact points are required, a wider receiving plate can be used directly, and the wires can be quickly connected through the fixing components; when the contact point requirement is reduced, a narrower receiving plate can be selected, which greatly improves the flexibility of the terminal to adapt to the multi-contact requirements of different scenarios. 2. By fixing anti-detachment plates to both sides of the terminal pins and ensuring that the surface of the anti-detachment plates is in close contact with the inner wall of the insertion slot, a dual constraint of "sliding connection + lateral limiting" is formed. On the one hand, the terminal pins can slide directly into the insertion slot, improving the speed of assembly; on the other hand, the anti-detachment plates can effectively limit the radial displacement of the terminal pins, effectively solving the problem of "loosening and offset" caused by vibration of traditional terminal pins, and ensuring stable docking of multiple contact points. 3. To address the connection requirements of multi-strand output wires, a combination structure of "shunt bundle sleeve + main bundle sleeve" is used to achieve "straight-by-straight fixing + overall constraint" of the wires. The shunt bundle sleeve can be fitted and fixed to each sub-strand of the output wire, thereby effectively transmitting the electrical signal to the sub-strand. The main bundle sleeve fixes the entire bus as a whole, increasing the fixing effect and ensuring that it will not detach from the fixing components. Attached Figure Description

[0012] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0013] Please see Figures 1-4 This utility model provides an embodiment of a connector terminal with multiple contact points, including a receiving plate 4. A plug 3 is fixedly connected to the surface of the receiving plate 4. An installation groove 13 is provided in the receiving plate 4. A plug groove 12 is provided in the plug 3 and the receiving plate 4, and the plug groove 12 and the installation groove 13 are interconnected. A fixing component is provided in the plug groove 12 and the installation groove 13, and an output wire 14 is installed in the plug groove 12 and the installation groove 13 through the fixing component. A rectangular installation groove 13 is formed in the receiving plate 4 along the length direction. The plug groove 12 is provided through the plug 3 and the receiving plate 4. One end of the plug groove 12 extends to the external docking port of the plug 3, and the other end is completely connected to the installation groove 13.

[0014] In this embodiment, the fixing assembly includes terminal pins 7 and anti-detachment plates 8. Terminal pins 7 are slidably connected within the connector 3, and anti-detachment plates 8 are fixedly connected to both sides of the terminal pins 7. Both terminal pins 7 and anti-detachment plates 8 are placed within the insertion slot 12, with the surface of the anti-detachment plates 8 tightly abutting the inner sidewall of the insertion slot 12. The fixing assembly also includes a conductive plate 5 and a positioning plate 6. Conductive plates 5 are fixedly connected to the upper and lower end faces of the terminal pins 7, and positioning plates 6 are fixedly connected to both sides of the conductive plates 5. One end of the positioning plate 6 is inserted into the insertion slot 12, and the other end of the positioning plate 6 is placed in the mounting slot 13. The positioning plate 6 is L-shaped overall. The fixing assembly also includes a shunt nozzle sleeve 9 and a main bundle. The nozzle sleeve 10 and the positioning plate 6 are fixedly connected at one end to a shunt nozzle sleeve 9, and at the other end of the shunt nozzle sleeve 9 to a main nozzle sleeve 10. The fixing assembly also includes a fixing sleeve 11 and an output wire 14. The output wire 14 is sleeved inside the main nozzle sleeve 10, and the output wire 14 is a multi-strand wire. The shunt nozzle sleeve 9 is also sleeved on the surface of the sub-strands of the output wire 14. The fixing sleeve 11 is fixedly connected to the surface of the output wire 14. The receiving plate 4 is fixedly connected to the upper end of a connecting plate 2, and the connecting plate 2 is fixedly connected to the upper end of a snap-fit ​​plate 1. The anti-detachment plate 8 is fixed to both sides of the terminal pin 7 by welding and fixed to the upper and lower ends of the terminal pin 7 by riveting. The positioning plate 6 is L-shaped. The structure is fixed to both sides of the conductive plate 5 with screws. One end of the positioning plate 6 is adapted to the depth of the insertion slot 12, and the other end is adapted to the width of the mounting slot 13. This ensures that when the fixing component is inserted into the insertion slot 12, it can only be fixed in a predetermined position. The output wire 14 is fixed by the shunt port sleeve 9 and the main port sleeve 10, and the electrical signal of the output wire 14 is conducted through the fixing component.

[0015] When the connector terminals are in operation, the appropriate width of the receiving plate 4 is selected based on the actual number of contact points required. A wider receiving plate 4 is used for more contact points (accommodating more connectors 3), while a narrower receiving plate 4 is selected for fewer contact points. The preset width allows for quick matching of the number of connectors 3 with the required number of contact points. During assembly, the terminal pins 7 with anti-disengagement plates 8 are slid into the insertion slots 12. The anti-disengagement plates 8 adhere tightly to the slot walls, forming a double constraint that allows the terminal pins 7 to be quickly inserted into place while limiting their radial displacement. Then, L is fixed. The positioning plate 6 is inserted into the plug slot 12 at one end and fixed to the mounting slot 13 at the other end, ensuring that the conductive plate 5 and the terminal pins 7 are precisely aligned to the predetermined position. Then, the multi-strand output wires 14 are combed and fixed by the shunt sleeve 9 and the main sleeve 10, completing the connection between the wires and the fixing components. During operation, the external device connects to the terminal through the plug 3. The electrical signal is transmitted to the upper and lower conductive plates 5 through the terminal pins 7, and then shunt by the conductive plates 5 to each sub-strand wire. The shunt sleeve 9 ensures stable signal transmission for each wire, and the main sleeve 10 prevents the wires from detaching. During equipment operation, the anti-detachment plate 8 and the positioning plate 6 together maintain the stable position of the terminal pins 7 and the conductive plate 5, avoiding poor contact caused by vibration, and realizing efficient and stable signal and current transmission at multiple contact points.

[0016] The integrated structure of "receiving plate 4 + connector 3" creates a continuous space for "external docking - internal installation" by forming an mounting groove 13 within the receiving plate 4 and a connecting groove 12 that runs through the connector 3 and the receiving plate 4. The width of the receiving plate 4 can be flexibly increased or decreased according to the actual number of contact points required, thereby increasing or decreasing the number of connectors 3. When more contact points are needed, a wider receiving plate 4 can be used, and wires can be quickly connected via a fixing component. When the contact point requirement is reduced, a narrower receiving plate 4 can be selected, significantly improving the terminal's adaptability to multi-contact requirements in different scenarios. Anti-detachment plates 8 are fixedly connected to both sides of the terminal pin 7, with the surface of the anti-detachment plates 8 tightly against the inner wall of the connecting groove 12, forming a "sliding connection + lateral limiting" mechanism. The dual constraints allow for two main benefits. First, the terminal pin 7 can slide directly into the insertion slot 12, improving the speed of assembly. Second, the anti-detachment plate 8 effectively limits the radial displacement of the terminal pin 7, effectively solving the problem of "loosening and offset" caused by vibration in traditional terminal pin 7, and ensuring stable connection of multiple contact points. For the connection requirements of multi-strand output wires 14, the combination structure of "shunt sleeve 9 + main sleeve 10" achieves "straight-by-straight fixing + overall constraint" of the wires. The shunt sleeve 9 can be sleeved and fixed to each sub-strand of the output wire 14, thereby effectively transmitting the electrical signal to the sub-strand. The main sleeve 10 fixes the bus as a whole, increasing the fixing effect and ensuring that it will not detach from the fixing components.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
