Description

Technical Field

[0001] This utility model relates to the field of LVDS patch connector technology, and in particular to an LVDS horizontal patch connector. Background Technology

[0002] LVDS horizontal surface mount connectors are surface mount components that utilize low-voltage differential signal technology and are mounted horizontally. Their core function is to stably and reliably transmit high-speed differential signals between circuit boards. They transmit high-speed data signals from one end to the other with low voltage, low power consumption, and high interference immunity. Their horizontal structure effectively saves vertical space, making them widely used in electronic devices with high requirements for signal integrity and spatial layout, such as LCD displays, in-vehicle entertainment systems, and industrial control equipment.

[0003] However, existing connectors lack reliable fixation after the line plug is inserted into the female socket, and are easily detached by external force, affecting the stability of signal transmission. At the same time, the heat dissipation design of the terminals is relatively simple, relying mostly on natural heat dissipation, which leads to rapid heat accumulation and excessively high terminal temperature, shortening the life of the connector. Therefore, we propose an LVDS horizontal surface mount connector to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing connectors, such as the lack of reliable fixation after the connector wire end plug is inserted into the female socket, easy detachment under external force affecting signal transmission stability, and simple terminal heat dissipation design relying on natural heat dissipation, resulting in rapid heat accumulation leading to high temperature and short lifespan. Therefore, this invention proposes an LVDS horizontal surface mount connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An LVDS horizontal surface mount connector includes a female connector and a mounting box. The female connector is fixedly embedded inside the mounting box by a fixing component. A horizontal insertion interface is provided on one side of the female connector. Multiple terminal slots are provided on the bottom inner wall of the insertion interface. Multiple through holes communicating with the corresponding terminal slots are provided on one side of the female connector. Terminals are fixedly disposed inside the multiple terminal slots. One end of the multiple terminals passes through the corresponding through hole and extends to the outside of the female connector.

[0007] The mounting box is provided with a limiting component, which includes multiple elastic fixing pieces III fixed to the inner wall of the top of the mounting box. Each of the multiple elastic fixing pieces III has an opening, and two elastic pressure pieces are fixedly connected to the inner wall of one side of each opening.

[0008] The female connector is provided with a heat dissipation assembly, which includes multiple heat dissipation holes opened on the top of the female connector. Each of the multiple heat dissipation holes has an insulating heat-conducting block embedded inside. The bottom end of the insulating heat-conducting block abuts against the outer wall of the terminal disposed in the female connector.

[0009] In one possible design, the fixing component includes a plurality of elastic fixing pieces I, which are fixedly disposed on one side of the mounting box, and a slot I corresponding to the plurality of elastic fixing pieces I is provided on one side of the female base.

[0010] In one possible design, the fixing component further includes two elastic fixing pieces II, which are symmetrically fixed to one side of the inner wall of the mounting box. The female socket has a slot II corresponding to the two elastic fixing pieces II on one side of the insertion interface, and both slots II are connected to the insertion interface.

[0011] In one possible design, the female connector has a slot III corresponding to a plurality of elastic fixing pieces III on one side of the insertion interface, and the plurality of slots III are all interconnected with the interior of the insertion interface. When the female connector is inserted into the mounting box, the plurality of elastic fixing pieces III are inserted into the interior of the corresponding slots III, and the bottom of the plurality of elastic pressure pieces extends into the interior of the insertion interface.

[0012] In one possible design, the heat dissipation assembly further includes a heat-conducting plate, the top of the female base has a groove, the heat-conducting plate is embedded in the groove of the female base, and the bottom of the heat-conducting plate has a socket corresponding to a plurality of insulating heat-conducting blocks, the tops of the plurality of insulating heat-conducting blocks are inserted into the corresponding sockets.

[0013] In one possible design, the bottom inner wall of the groove is fixedly provided with multiple positioning protrusions, and the bottom of the heat-conducting sheet is provided with positioning grooves corresponding to the positioning protrusions. When the heat-conducting sheet is embedded in the groove of the female seat, the multiple positioning protrusions are inserted into the corresponding positioning grooves.

[0014] In one possible design, connecting pieces are fixedly connected to both sides of the heat-conducting sheet. When the female seat is embedded in the mounting box, the top inner wall of the mounting box presses against the tops of the two connecting pieces and fixes them in place.

[0015] In this application, firstly, the terminals are fixed in the terminal slots of the female connector. Then, the insulating heat-conducting block is embedded into the heat dissipation hole of the female connector, so that the bottom end of the insulating heat-conducting block abuts against the outer wall of the terminal. This prepares for the subsequent establishment of a heat conduction path from the internal heat source to the outside, ensuring that heat can be smoothly transferred from the terminal to the insulating heat-conducting block. After that, the heat-conducting plate is embedded into the groove on the top of the female connector, so that the insertion hole of the heat-conducting plate corresponds to the insulating heat-conducting block. At the same time, the positioning protrusion at the bottom of the groove is inserted into the positioning groove of the heat-conducting plate. Through the cooperation of the positioning groove and the positioning protrusion, the heat dissipation module is quickly positioned and guided, simplifying the assembly process. At the same time, it ensures the accurate docking of the heat-conducting plate and the insulating heat-conducting block, providing a stable foundation for heat collection and transfer.

[0016] Next, during the process of embedding the female connector into the mounting box, the elastic fixing piece I of the mounting box will be inserted into the slot I of the female connector, and the elastic fixing piece II on one side of the mounting box will be inserted into the slot II of the female connector. Through the cooperation of these two sets of elastic fixing pieces and slots, the connection strength between the female connector and the mounting box is enhanced, preventing the female connector from shifting or loosening during use. At the same time, the elastic fixing piece III on the top inner wall of the mounting box is inserted into the slot III of the female connector, and the connecting pieces on both sides of the heat conduction plate are squeezed by the top inner wall of the mounting box. The continuous pressure generated by the compression of the connecting pieces by the mounting box firmly presses the heat dissipation module onto the female connector, ensuring close contact of the heat channel interface and improving heat dissipation reliability. At the same time, the elastic pressure piece on the elastic fixing piece III extends into the insertion interface.

[0017] When the plug is inserted into the female connector, the elastic clamp abuts against the top of the plug, applying uniform pressure to the plug surface to create a distributed pressing effect. This improves vibration and shock resistance, ensuring a continuous and reliable electrical connection in harsh environments. At this time, the terminal and plug are in stable contact to transmit signals. The heat generated by the terminal during high-speed signal transmission is transferred to the heat-conducting plate through the insulating heat-conducting block, and then dissipated through the heat conduction path formed by the heat-conducting plate. This significantly reduces the terminal's operating temperature, effectively delays plastic aging, and maintains the stability of signal transmission.

[0018] Beneficial effects: In this utility model, the LVDS horizontal patch connector, by setting an insulating heat-conducting block above the female terminal slot, so that its bottom directly contacts the terminal, and the top forms a heat conduction path with the mounting box through a heat-conducting plate, establishes an efficient heat dissipation channel from the internal heat source to the external metal shell, which can significantly reduce the operating temperature of the terminal during high-speed signal transmission, effectively delay plastic aging and maintain the stability of signal transmission.

[0019] In this utility model, the LVDS horizontal patch connector forms a distributed crimping effect when the plug is inserted through the cooperation structure of multiple elastic fixing plates and slots. The elastic pressure plate on the elastic fixing plate III can simultaneously apply uniform pressure to the plug surface. This multi-point fixing method enhances the mechanical connection strength between the plug and the socket, improves the vibration and impact resistance, and ensures a continuous and reliable electrical connection in harsh environments.

[0020] In this invention, the LVDS horizontal patch connector achieves rapid positioning and guidance of the heat dissipation module by engaging the positioning groove at the bottom of the heat-conducting plate with the positioning protrusion in the groove of the female connector. Simultaneously, when the female connector is embedded in the mounting box, the inner wall of the mounting box presses the connecting pieces on both sides of the heat-conducting plate, generating continuous pressure through elastic deformation, firmly pressing the heat dissipation module onto the female connector. This structure simplifies the assembly process, ensures tight contact of the thermal channel interface, and significantly improves heat dissipation reliability and assembly consistency.

[0021] In this invention, an efficient heat dissipation channel is formed by the insulating heat-conducting block above the female terminal slot, the heat-conducting sheet, and the mounting box. This significantly reduces the operating temperature of the terminal during high-speed signal transmission, slows down plastic aging, and maintains signal stability. The cooperation of multiple elastic fixing plates with the slots and the multi-point pressure of the elastic pressure plates enhance the mechanical connection strength between the plug and the socket, improve vibration and impact resistance, and ensure reliable electrical connection in harsh environments. The cooperation between the heat-conducting sheet positioning groove and the female protrusion simplifies assembly. The mounting box squeezes the connecting piece to generate continuous pressure, ensuring tight contact at the thermal channel interface and improving heat dissipation reliability and assembly consistency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Refer to Figure 1-5 A surface mount connector includes a female connector 1 and a mounting box 2. The female connector 1 is fixedly embedded inside the mounting box 2 by a fixing component. A horizontal insertion interface is provided on one side of the female connector 1. Multiple terminal slots 3 are provided on the bottom inner wall of the insertion interface. Multiple through holes communicating with the corresponding terminal slots 3 are also provided on one side of the female connector 1. A terminal 4 is fixedly provided inside each of the multiple terminal slots 3. One end of the multiple terminals 4 passes through the corresponding through hole and extends to the outside of the female connector 1. The terminals 4 provide the basic components for the connector to realize signal transmission.

[0030] The female connector 1 is equipped with a heat dissipation assembly, which includes multiple heat dissipation holes on the top of the female connector 1. Each heat dissipation hole is connected to a corresponding terminal slot 3. An insulating heat-conducting block 6 is embedded inside each heat dissipation hole. The bottom end of the insulating heat-conducting block 6 abuts against the outer wall of the corresponding terminal 4. This structure allows the insulating heat-conducting block 6 to directly contact the terminal 4, preparing for the subsequent establishment of a heat conduction path from the internal heat source to the outside, ensuring that heat can be smoothly transferred from the terminal 4 to the insulating heat-conducting block 6. The heat dissipation assembly also includes a heat-conducting plate 7. A groove is formed on the top of the female connector 1, and the heat-conducting plate 7 is embedded in the groove. The bottom of the heat-conducting plate 7 has insertion holes corresponding to the multiple insulating heat-conducting blocks 6. The multiple insulating heat-conducting blocks 6 are inserted into the corresponding insertion holes. The heat absorbed by the multiple insulating heat-conducting blocks 6 can be collected by the heat-conducting plate 7 for subsequent centralized dissipation.

[0031] Multiple positioning protrusions 8 are fixedly provided on the inner wall of the bottom of the groove. The bottom of the heat-conducting plate 7 is provided with positioning grooves corresponding to the positioning protrusions 8. When the heat-conducting plate 7 is embedded in the groove of the female seat 1, the multiple positioning protrusions 8 are inserted into the corresponding positioning grooves. Through the cooperation of the positioning grooves and positioning protrusions 8, the heat dissipation module can be quickly positioned and guided, simplifying the assembly process. At the same time, it ensures the accurate docking of the heat-conducting plate 7 and the insulating heat-conducting block 6, providing a stable foundation for heat collection and transfer. Connecting pieces 701 are fixedly connected to both sides of the heat-conducting plate 7. When the female seat 1 is embedded in the mounting box 2, the top inner wall of the mounting box 2 presses the tops of the two connecting pieces 701 for fixation. The continuous pressure generated by the mounting box 2 on the connecting pieces 701 can firmly press the heat dissipation module onto the female seat 1, ensuring tight contact of the thermal channel interface and significantly improving the reliability of heat dissipation.

[0032] The mounting box 2 is equipped with a limiting component to secure the cable plug when it is inserted into the connector at the top of the female connector 1. The limiting component includes multiple elastic fixing pieces Ⅲ203 fixed to the inner wall of the top of the mounting box 2. Each elastic fixing piece Ⅲ203 has an opening, and two elastic pressure pieces 5 are fixedly connected to one side of the inner wall of each opening. The female connector 1 has a slot Ⅲ103 on one side of the connector corresponding to the multiple elastic fixing pieces Ⅲ203. The multiple slots Ⅲ103 are interconnected with the inside of the connector. When the female connector 1 is inserted into the mounting box 2, the multiple elastic fixing pieces Ⅲ203 are inserted into the corresponding slots Ⅲ103, and the bottom of the multiple elastic pressure pieces 5 extends into the inside of the connector, preparing for subsequent fixing of the cable plug.

[0033] This application can be used in the field of LVDS patch connection technology, as well as in other fields applicable to this application.

[0034] In another embodiment: Reference Figure 1-3 An improvement based on Embodiment 1: An LVDS horizontal patch connector, which is applied to the field of LVDS patch connection technology, includes a fixing component comprising multiple elastic fixing pieces I201, which are fixedly disposed near one side of the mounting box 2. One side of the female connector 1 is provided with slots I101 corresponding to the multiple elastic fixing pieces I201. When the female connector 1 is embedded in the mounting box 2, the multiple elastic fixing pieces I201 are inserted into the corresponding slots I101. Two elastic fixing pieces II202 are symmetrically fixed on one inner wall of the mounting box 2. The female seat 1 has a slot II102 corresponding to the two elastic fixing pieces II202 on one side of the insertion interface. Both slots II102 are connected to the insertion interface. When the female seat 1 is inserted into the mounting box 2, the two elastic fixing pieces II202 are inserted into the corresponding slots II102. Through the cooperation of the elastic fixing pieces I201 and slots I101, and the elastic fixing pieces II202 and slots II102, the connection strength between the female seat 1 and the mounting box 2 can be enhanced, and the female seat 1 can be prevented from shifting or loosening during use.

[0035] When the plug is inserted into the socket of the female connector 1, multiple elastic pressure plates 5 abut against the top of the plug, applying uniform pressure to the plug surface and creating a distributed pressing effect. This multi-point fixing method enhances the mechanical connection strength between the plug and the female connector 1, improves vibration and shock resistance, and ensures a continuous and reliable electrical connection in harsh environments. At this time, the terminal 4 is in stable contact with the plug to transmit signals. The heat generated by the terminal 4 during high-speed signal transmission is transferred to the heat-conducting plate 7 through the insulating heat-conducting block 6, and then dissipated through the heat conduction path formed by the heat-conducting plate 7, significantly reducing the operating temperature of the terminal 4, effectively delaying plastic aging and maintaining the stability of signal transmission.
