Description

Technical Field

[0001] This application relates to the field of electrical connector technology in the industrial, energy and automation sectors, and in particular to a six-pin connector. Background Technology

[0002] In the industrial, energy, and automation sectors, electrical connectors are critical components ensuring stable equipment operation. They must be adaptable to harsh environments such as high temperatures and outdoor conditions, while meeting the dual requirements of high-current and signal transmission. Existing connectors, to cope with high-temperature environments, often use high-temperature resistant PVC or silicone materials to encapsulate the body. However, these materials are prone to embrittlement when exposed to ultraviolet radiation for extended periods, resulting in a short outdoor lifespan. Conductive parts commonly use pure copper or gold-plated terminals, without differentiated design for high-current and signal circuits, which can easily lead to signal interference and affect transmission stability. In terms of temperature monitoring, conventional solutions require external independent sensors, which not only increases installation complexity but may also introduce measurement delays or errors, making accurate real-time monitoring difficult. While some integrated injection-molded connectors simplify the structure, their internal structure lacks strength and is prone to deformation after long-term use, leading to loose terminal fixation and further affecting electrical performance. In addition, existing connectors also suffer from limited functionality and inconvenient maintenance, failing to meet the high-precision, high-stability, and integrated requirements of high-end equipment, thus limiting their application scope. Therefore, a six-pin connector is provided. Utility Model Content

[0003] The purpose of this application is to provide a six-pin connector that solves the problems of insufficient UV resistance and short outdoor life of existing connector high-temperature resistant materials, making it suitable for harsh environments. It also solves the problems of insufficient inner tube strength and loose terminals, meeting the requirements of integration and high stability. Furthermore, it solves the problem of inconvenient maintenance of existing connectors, reduces the probability of wiring errors, improves troubleshooting efficiency, and simplifies the maintenance process.

[0011] Preferably, the outer covering structure of the connecting seat body is made by injection molding, and the parting line of the outer covering structure has no obvious burrs.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0024] Example 1: A six-pin connector, as shown in the figure. Figure 1 , Figure 2 and Figure 5The connector body includes a connector main body 1, a terminal assembly 2, a wire assembly 3, and a temperature sensor module 4. The connector main body 1 includes an outer covering structure 11 and an inner liner 12, with the outer covering structure 11 covering the outside of the inner liner 12. The terminal assembly 2 includes two first male terminals 21 for transmitting signals, four second male terminals 22 for transmitting large currents, and a flag-shaped terminal 23 for connecting the temperature sensor module 4. The flag-shaped terminal 23 is electrically connected to one of the first male terminals 21, forming a six-core circuit. The terminal assembly 2 is connected to the wire assembly 3. The temperature sensor module 4 is integrated into the six-core circuit. The inner liner 12 is used to fix the terminal assembly 2. The outer layer of the outer covering structure 11 is a PVC covering layer. The high-temperature and UV-resistant PVC material of the outer covering structure 11 can isolate high temperature and ultraviolet rays, solving the problems of insufficient UV resistance and short outdoor life of existing connector high-temperature materials, and making it suitable for harsh environments. The brass inner tube 12 has high strength and can stably fix the terminal assembly 2, preventing the inner tube 12 from deforming and causing the terminals to loosen, thus ensuring stable electrical performance. The first male terminal 21 and the second male terminal 22 realize differentiated transmission of signals and high currents, avoiding signal interference. The temperature sensor module 4 is integrated into the six-core circuit through the flag-shaped terminal 23, eliminating the need for an external sensor, simplifying installation, avoiding temperature measurement delay errors, and meeting the requirements of integration and high stability.

[0025] Reference Figure 1 and Figure 2 The wire assembly 3 includes four second-specification wires 32 for high-current transmission and two first-specification wires 31 for signal transmission. The two first-specification wires 31 are connected to two first male terminals 21 respectively, and the four second-specification wires 32 are connected to four second male terminals 22 respectively. The first-specification wires 31 and the second-specification wires 32 of the wire assembly 3 are distinguished by color to indicate different functional circuits. The first-specification wires 31 are matched with the first male terminals 21 to transmit signals, and the second-specification wires 32 are matched with the second male terminals 22 to transmit high current. This achieves functional adaptation between the wires and terminals, further enhances differentiated transmission, avoids transmission failures caused by wire and terminal mismatch, improves electrical performance stability, and makes up for the defects of the lack of differentiation between existing connector wires and terminals. By quickly identifying the functional circuit of the wires by color, the probability of wiring errors during installation is reduced. During later maintenance and troubleshooting, the corresponding circuit can be quickly located, solving the problem of inconvenient maintenance of existing connectors and improving installation and maintenance efficiency.

[0026] Reference Figure 1 , Figure 2 and Figure 3The connection end of the first male terminal 21 and the wire assembly 3 is tinned. The flag-shaped terminal 23 is covered with a nylon sheath 5. The outer layer covering structure 11 of the connector body 1 is made by injection molding. The parting line of the outer layer covering structure 11 has no obvious burrs. Tinning the connection end of the first male terminal 21 enhances the tightness of the connection with the wire and prevents poor contact. The nylon sheath 5 of the flag-shaped terminal 23 can isolate external contact, avoid the risk of short circuit, improve the reliability of electrical connection and safety of use, and reduce equipment failure caused by terminal connection problems. The injection molding process and the parting line design without obvious burrs ensure that the outer layer covering structure 11 is structurally complete and has a flat appearance, avoids installation jamming or structural damage caused by burrs, improves product consistency and service life, and solves the problem of insufficient manufacturing precision of existing integrated injection molded connectors.

[0027] Reference Figure 1 , Figure 4 and Figure 5 The inner liner 12 is made of brass or high-strength aluminum alloy. The temperature sensor module 4 is a thermistor. The connector body 1 adopts a two-section structure with a baffle. The outer covering structure 11 meets the preset temperature resistance level and electrical performance requirements. The wire assembly 3 is wrapped with a shielding layer 13 to reduce signal interference. The inner liner 12 can be replaced with high-strength aluminum alloy, and the temperature sensor module 4 can be replaced with a thermistor with a specific temperature coefficient. The configuration can be flexibly adjusted according to different usage scenarios, expanding the product application range and avoiding the limitations of existing connectors with single functions and limited adaptability. The two-section structure with a baffle facilitates positioning during assembly and improves installation efficiency. The outer covering structure 11 meets the preset temperature resistance and electrical performance requirements, ensuring stable protection and insulation under specific working conditions, meeting the requirements of high-end equipment for installation accuracy and performance stability. The shielding layer 13 can isolate external electromagnetic interference, reduce the impact on the wire transmission signal, further improve signal transmission accuracy, solve the problem of existing connector signals being easily affected by external interference, and meet the signal transmission requirements of high-precision equipment.

[0028] In this embodiment, by setting up a connector body 1, a terminal assembly 2, and a temperature sensor module 4, the outer covering structure 11 covers the outside of the inner liner 12, and the high temperature and ultraviolet rays are isolated by the high temperature and ultraviolet rays of the outside through the high temperature and ultraviolet rays of the PVC material. The inner liner 12 is fixed with brass material to prevent the terminals from loosening. In the terminal assembly 2, the first male terminal 21 transmits signals and the second male terminal 22 transmits large current, realizing the differentiated transmission of the circuit. The temperature sensor module 4 is electrically connected to the first male terminal 21 through the flag-shaped terminal 23 and is integrated into the six-core circuit. It does not need to be external, which solves the problems of insufficient UV resistance and short outdoor life of existing connector high temperature resistant materials, and is suitable for harsh environments. The differentiated terminal design avoids signal interference and ensures stable transmission. The integrated temperature sensor eliminates the need for an external sensor, simplifies installation, avoids temperature measurement delay errors, and at the same time, the brass inner liner 12 solves the problems of insufficient strength of the inner liner 12 and loose terminals, meeting the requirements of integration and high stability.

[0029] The implementation principle of this application embodiment is as follows: First, the components are connected. The first specification wire 31 used for signal transmission in the wire assembly 3 is connected to the first male terminal 21 of the terminal assembly 2, and the second specification wire 32 used for high current transmission is connected to the second male terminal 22. At the same time, the temperature sensor module 4 is electrically connected to the first male terminal 21 through the flag-shaped terminal 23, so that the temperature sensor module 4 is integrated into the six-core circuit. Then, the assembled terminal assembly 2 is placed into the inner liner 12 of the connector body 1, and the inner liner 12 fixes the terminal assembly 2. Finally, the outer covering structure 11 is made by injection molding, so that it covers the outside of the inner liner 12, completing the overall assembly of the six-core connector. When the six-core connector is put into use, the electrical signal is transmitted through the circuit composed of the first male terminal 21 and the first specification wire 31, and the high current is transmitted through the circuit composed of the second male terminal 22 and the second specification wire 32, realizing the differentiated and independent transmission of signal and high current, avoiding mutual interference. At the same time, the temperature sensor module 4 monitors the internal and surrounding temperature of the connector in real time. The monitored temperature data is transmitted to the first male terminal 21 through the flag-shaped terminal 23, and then transmitted to the external control system through the first male terminal 21, completing the real-time monitoring and feedback of the temperature. The outer covering structure 11 of the connector body 1 is made of high-temperature resistant and UV-resistant PVC material, which can isolate external high temperature and UV corrosion, protect internal components, and is suitable for harsh environments such as outdoor and high temperature environments. The inner liner 12 is made of brass material, which ensures the long-term fixed stability of the terminal assembly 2 with its high strength characteristics and prevents the terminals from loosening. The connection end between the first male terminal 21 and the wire assembly 3 is tinned to enhance the tightness and conductivity of the connection between the two and prevent poor contact. The nylon sheath 5 on the outside of the flag-shaped terminal 23 can play an insulating protection role to prevent the flag-shaped terminal 23 from contacting other components and causing a short circuit. The outer covering structure 11 is manufactured using injection molding with no obvious burrs on the parting line, ensuring structural integrity and a smooth appearance, and preventing burrs from affecting installation or causing structural damage. The shielding layer 13 wrapped around the outside of the wire assembly 3 can isolate external electromagnetic interference, further improving the stability of signal transmission. The connector body 1 adopts a two-section structure with baffles, which facilitates positioning and installation during assembly and improves assembly efficiency. The outer covering structure 11 meets the preset temperature resistance level and electrical performance requirements, ensuring stable protection and insulation under specific working conditions. The inner liner 12 can be replaced with high-strength aluminum alloy, and the temperature sensor module 4 can be replaced with a thermistor that meets a specific temperature coefficient, allowing for flexible configuration adjustments according to different usage scenarios and improving product adaptability. The first specification wire 31 and the second specification wire 32 of the wire assembly 3 are distinguished by color to differentiate functional circuits, facilitating quick identification of wire uses during installation and maintenance and reducing operational difficulty.
