[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] Through analysis of existing technology, the inventors discovered several inherent shortcomings in current designs. First, the structural design of the terminal receiving slot is not well-matched to the terminal itself, potentially causing the terminal to wobble or misposition within the slot, affecting the long-term stability of the connection. Second, the assembly relationships between the terminals, the core, and the cable fixing components are not clearly defined or optimized, easily leading to inconsistent terminal insertion depths or poor contact. Furthermore, the mating precision between the interface and the terminal assembly needs improvement. These factors collectively limit the overall reliability of the connector.

[0019] In the embodiments of this application, addressing the problems of low flexibility of the housing 100 and poor matching between terminals and adhesive in the prior art, this application provides a solution with an internal terminal receiving slot and three types of housing 100, specifically: including a housing 100 and an adhesive core body 200, a terminal assembly 300, and a cable fixing assembly enclosed within the housing 100; one end of the terminal assembly 300 is embedded in the adhesive core body 200, and the other end of the terminal assembly 300 is embedded in the cable fixing assembly; the bottom of the adhesive core body 200 is provided with a mating interface 210 for connecting to achieve electrical connection, and the terminal assembly 300 is exposed in the mating interface 210; the adhesive core body 200 extends from the top into the wiring cavity and is provided with terminal receiving slots, which are arranged in parallel; wherein, the number of terminal receiving slots is the same as the number of terminal assemblies 300. This application provides an improved electrical connector, which overcomes the shortcomings of the prior art by optimizing the internal structural design, especially the integration and cooperation between the adhesive core body 200, the terminal assembly 300, and the cable fixing assembly. The advantages of this application lie in its high structural integration, simple assembly, and precise terminal positioning, which significantly improves the stability and reliability of electrical connections. The housing 100 offers high flexibility, convenient assembly, and a wide range of options.

[0020] Reference Figure 1-8 This diagram illustrates the structure of an electrical connector according to the present invention. Specifically, it includes a housing 100 and a core body 200, a terminal assembly 300, and a cable fixing assembly enclosed within the housing 100. One end of the terminal assembly 300 is embedded in the core body 200, and the other end is embedded in the cable fixing assembly. The core body 200 has a mating interface 210 at its bottom for connecting and achieving electrical connection, and the terminal assembly 300 is exposed in the mating interface 210. The core body 200 extends from its top into the wiring cavity and has terminal receiving slots arranged in parallel. The number of terminal receiving slots is the same as the number of terminal assemblies 300.

[0021] The following will further describe an electrical connector in this exemplary embodiment.

[0022] In this embodiment, the housing 100 includes an upper housing 110 and a lower housing 120, which are assembled by insertion or snap-fit. The upper housing 110 and the lower housing 120 cooperate to form a rectangular cavity. The lower housing 120 accommodates the adhesive core body 200, such as... Figure 2 As shown.

[0023] In one specific embodiment, the upper shell 110 is a cover-shaped component, and the lower shell 120 is a tray-shaped component. During assembly, they are assembled in opposite directions, with the upper shell 110 fastened onto the lower shell 120, which supports the core body 200. The inner edge of the upper shell 110 is provided with downwardly extending hooks or inserts, and correspondingly, the outer side wall of the lower shell 120 is provided with matching slots or grooves. Through the cooperation of the hooks and grooves, the upper shell 110 and the lower shell 120 can be tightly inserted or locked together, forming a robust rectangular cavity.

[0024] As an example, the bottom inner side of the lower shell 120 is provided with a receiving groove that matches the shape of the core body 200. The contour of the receiving groove can effectively limit the lateral movement of the core body 200, preventing it from shaking within the cavity. When the upper shell 110 and the lower shell 120 are fastened together, the inner top surface of the upper shell 110 will press against the top of the core body 200, thereby fixing it in the vertical direction.

[0025] In this embodiment, the housing 100 includes a flip cover 130 and an outer shell body 140 connected to the flip cover 130. The flip cover 130 and the outer shell body 140 cooperate to form a rectangular cavity, such as... Figure 4 As shown.

[0026] In one specific embodiment, improving assembly efficiency and reducing operational difficulty is an important issue in the production and assembly process of electrical connectors. Traditional connector housings are mostly split or fixed structures. When installing the internal core and cable, the operating space is limited, the assembly process is cumbersome, and production efficiency is affected. Especially for compact connectors, inconvenient assembly can easily lead to component damage or improper installation. This application provides a flip-top type electrical connector housing structure, solving the above-mentioned technical problems through a unique flip-top design. A flip-top type electrical connector housing structure includes a housing body 140 and a flip cover 130 connected to the housing body 140. The flip cover 130 is connected to the housing body 140 via a hinged connection structure, allowing the flip cover 130 to be flipped up and closed relative to the housing body 140. When the flip cover 130 is closed, the flip cover 130 and the housing body 140 cooperate to form a closed rectangular cavity for accommodating and protecting components such as the internal core 200.

[0027] As an example, the outer shell 140 is a U-shaped structure with the bottom and side walls integrally formed, a docking interface 210 at the front end, and a cable outlet at the rear end. The flip cover 130 is connected to the cable outlet at the rear end of the outer shell 140 via a flexible connecting part, forming a liftable cover structure. The front of the flip cover 130 has a snap-fit ​​structure, which locks with the corresponding structure at the front of the outer shell 140 when the flip cover 130 is closed, ensuring a stable closure of the outer shell. During assembly, the operator can first lift the flip cover 130 to fully expose the internal receiving space of the outer shell 140. Then, the core body 200 is vertically inserted into the positioning groove of the outer shell 140 from above the receiving space. This process is unobstructed by any structure and is simple and convenient. After the core body 200 is installed in place, the flip cover 130 is closed and locked to complete the assembly operation. The flip-cover design greatly improves the assembly processability of the connector. Compared with traditional structures, this application provides a wider operating space, making the installation of the core body 200 simple and intuitive, effectively improving assembly efficiency, reducing operation difficulty, and ensuring the structural integrity after the outer shell is closed and the effective protection of internal components.

[0028] In this embodiment, the housing 100 is integrally formed and is made of metal. This application provides an integrally formed metal housing structure, which is formed by die-casting metal material in one step to create a complete housing 100 structure. The housing 100 has an internal cavity for accommodating the core body 200, a docking interface 210 at one end, and a cable lead-out hole at the other end. The metal material provides excellent electromagnetic shielding performance and mechanical strength. The integrally formed structure completely eliminates the assembly process, avoiding quality problems caused by improper assembly, significantly improving production efficiency and product consistency, and making on-site installation simpler and more reliable. Figure 3 As shown.

[0029] In this embodiment, one end of the terminal assembly 300 is embedded in the core body 200, and the core body 200 has a docking interface 210 at its bottom for connecting and realizing electrical connection. The terminal assembly 300 is exposed in the docking interface 210. The core body 200 extends from the top into the wiring cavity and has a terminal receiving groove, which is arranged in parallel. The number of terminal receiving grooves is the same as the number of terminal assemblies 300.

[0030] In this embodiment, the top of the housing 100 is provided with a fixing plate and a fork-shaped connector; the fork-shaped connector is U-shaped and is disposed opposite to the fixing plate. The fork-shaped connector is disposed on the flip cover 130 or the upper shell 110, and the fixing plate is disposed on the lower shell 120 or the outer shell body 140.

[0031] As an example, one end of the terminal assembly 300 is securely embedded within the core body 200. The bottom of the core body 200 has a mating interface 210 for engaging with a matching connector to achieve an electrical connection; the contact portion of the terminal assembly 300 is exposed in this mating interface 210. The top of the core body 200 extends downward to form a wiring cavity, which contains multiple parallel terminal receiving slots. The number of terminal receiving slots is the same as the number of terminal assemblies 300, with each slot precisely corresponding to and accommodating one terminal assembly 300.

[0032] In this embodiment of the application, the adhesive core body 200 is provided with inwardly recessed snap-fit ​​grooves on both sides; the housing 100 is provided with snaps at positions corresponding to the snap-fit ​​grooves.

[0033] In this embodiment, the terminal assembly 300 includes a signal terminal 320 and a power terminal 310 arranged parallel to the signal terminal 320; the signal terminal 320 is exposed inside the docking interface 210, and the power terminal 310 is exposed outside the docking interface 210. The signal terminal 320 includes a first terminal, a second terminal, a third terminal, and a fourth terminal; the first terminal and the second terminal are arranged side by side, and the third terminal and the fourth terminal are arranged side by side.

[0034] In one specific embodiment, the composite terminal assembly 300 includes a signal terminal 320 and a power terminal 310, which are arranged parallel to each other at the mating interface 210 of the connector. The signal terminal 320 is exposed in the inner region of the mating interface 210, while the power terminal 310 is exposed in the outer region of the mating interface 210.

[0035] In one specific embodiment, the signal terminal 320 specifically includes a first terminal, a second terminal, a third terminal, and a fourth terminal. The first terminal and the second terminal are arranged side by side to form a first signal pair; the third terminal and the fourth terminal are arranged side by side to form a second signal pair. This paired side-by-side arrangement is beneficial for forming differential signal transmission pairs and improving the ability to resist common-mode interference.

[0036] By arranging the power terminal 310 on the outside of the mating interface 210 and the signal terminal 320 on the inside, this application effectively increases the distance between the susceptible signal terminal 320 and the strong interference source in space. It also utilizes the connector's own structure to form a certain degree of physical isolation, which effectively reduces the electromagnetic coupling and interference caused by power transmission to signal transmission, significantly improves signal integrity, and ensures the reliability of the connector in complex electromagnetic environments.

[0037] In this embodiment of the application, the cable fixing assembly includes a rear plug 400 and a wire clamp 500 for fixing the cable; one end of the rear plug 400 is connected to the wire clamp 500, and the other end of the rear plug 400 is connected to the rubber core body 200.
