Currently, the USB port connecting connectors on the market are usually arranged in the shell by the way of buckle connection of the internal structure. This design achieves the fixed connection of the internal structure and the shell to a certain extent, ensuring the stability and reliability of the connector under normal use.

[0003] However, as the use time increases, this buckle connection gradually exposes some problems. Specifically, because the buckle will be subjected to repeated plugging force and external force impact during long-term use, its elasticity will gradually weaken, and even deformation will occur. This causes the fixed connection between the internal structure and the shell to become loose, and the internal structure is loose. Once the internal structure is loose, it will affect the plugging performance of the connecting connector. During plugging, the loose internal structure may cause poor contact, thereby causing unstable signal transmission, data transmission error and other problems.

[0004] In addition, the loosening of the internal structure may also negatively affect the mechanical strength of the connecting connector. When subjected to external force impact or vibration, the loose internal structure is more likely to be damaged, thereby shortening the service life of the connecting connector.

[0039] ​​​It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0041] In the present application, unless otherwise stated, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or directed to the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application.

[0042] In order to solve the problem that the internal structure of the USB port connecting connector is prone to looseness in the prior art, the present application provides a new USB port connecting connector.

[0043] The present application will be described in further detail below in combination with the drawings and specific embodiments.

[0044] As shown in Figures 1-4 The present embodiment provides a USB port connecting connector, which comprises a shell 1 and an internal structure 2, and aims to solve the problem that the internal structure 2 is prone to looseness in the prior art.

[0045] The shell 1 is provided with a positioning through slot 11 for positioning the internal structure 2. The shell 1 also has a recess 12 towards its interior, which is formed by a blocking wall 121 protruding towards the interior of the shell.

[0046] The internal structure 2 is arranged in the shell 1 by means of snap connection, and has a clamping rib 21 arranged in the recess 12 and a positioning protrusion 22 arranged in the positioning through slot 11. When the internal structure 2 is installed in the shell 1, the clamping rib 21 abuts against the blocking wall 121 to achieve close connection, and the positioning protrusion 22 is clamped in the positioning through slot 11, thereby enhancing the stability of the internal structure 2 in the shell 1. The blocking wall 121 has good elastic force and is not prone to elastic fatigue during use, which can effectively prevent looseness after long-term use.

[0047] Further, with reference to Figure 2As shown, the housing 1 is designed with a receiving cavity 13 for accommodating the internal structure 2, and a plug-in interface 14 for the plug-in connection of external devices. The clamping rib 21 on the internal structure 2 is formed in a direction perpendicular to the plug-in and plug-out direction of the plug-in interface 14. This design enables the clamping rib 21 to be in close abutment with the blocking wall 121 of the recess 12 when the internal structure 2 is installed in the housing 1, thereby effectively enhancing the stability of the internal structure 2 in the plug-in and plug-out direction and preventing loosening that may occur during long-term use.

[0048] With reference to Figures 1-2 As shown, the number of recesses 12 is set to at least two, and the recesses 12 are spaced apart in a direction perpendicular to the plug-in and plug-out direction, ensuring that the internal structure 2 is stably supported at multiple points. Each recess 12 is formed by stamping the side wall 15 of the housing 1, which not only ensures the structural strength of the blocking wall 121, but also makes the cooperation between the housing 1 and the internal structure 2 more compact and reliable. When the internal structure 2 is installed in the housing 1, the clamping rib 21 thereof is in abutment with multiple blocking walls 121, further enhancing the stability of the connection joint and effectively preventing loosening after long-term use.

[0049] Further, with reference to Figure 3 As shown, the side wall 15 has a stamping hole 151 for forming the blocking wall 121 by stamping, and the orthographic projection of the stamping hole 151 on the outside of the side wall 15 is a rectangle. This design not only facilitates processing and manufacturing, but also ensures structural consistency. The blocking wall 121 includes a first blocking wall 1211 and a second blocking wall 1212 that protrude towards the inside of the housing 1 from opposite sides of the rectangle. The first blocking wall 1211 and the second blocking wall 1212 gradually approach and eventually intersect each other during the process of extending away from the stamping hole 151 towards the inside of the housing 1. This structural design enables the blocking wall 121 to effectively abut the clamping rib 21 of the internal structure 2, providing stable support and further enhancing the stability and reliability of the connection joint, effectively resisting loosening that may occur during long-term use.

[0050] In this embodiment, preferably, the rectangle has two opposite sides in a direction perpendicular to the plug-in and plug-out direction of the plug-in interface 14. This design takes into account the installation requirements and stability requirements of the internal structure 2.

[0051] Specifically, the first barrier wall 1211 protrudes from one of the two sides towards the inside of the shell 1, and the second barrier wall 1212 protrudes from the other of the two sides towards the inside of the shell 1, and the first barrier wall 1211 and the second barrier wall 1212 gradually approach and finally intersect during the extension towards the inside of the shell 1. Such a layout enables the first barrier wall 1211 and the second barrier wall 1212 to support and fix the clamping ribs 21 of the internal structure 2 from the two sides respectively, ensuring the stability and reliability of the USB port connecting joint in the plugging direction, and effectively preventing loosening or displacement that may occur during long-term use.

[0052] In the embodiment, referring to Figure 3 As shown in the figure, optionally, the first barrier wall 1211 and the second barrier wall 1212 form an acute angle with the plane where the side wall 15 is located, and the acute angle is carefully designed within the range of 60-90°. Such a design not only ensures the sufficient strength and rigidity of the barrier wall 121, but also enables the barrier wall 121 to provide good support and guiding effect when cooperating with the clamping ribs 21 of the internal structure 2. At the same time, the design of the acute angle also helps to reduce stress concentration, improve the durability and reliability of the connecting joint, and ensure the stable performance of the product during long-term use.

[0053] Then referring to Figure 4 As shown in the figure, in the embodiment, the internal structure 2 is mainly composed of an insulating plastic body 23, which has good insulation performance and mechanical strength and can effectively protect the internal electrical elements. On the insulating plastic body 23, the clamping ribs 21 and the positioning protrusions 22 are arranged. The clamping ribs 21 are used to cooperate with the first barrier wall 1211 and the second barrier wall 1212 on the shell 1 to achieve stable connection, and the positioning protrusions 22 are used to ensure the accurate positioning of the internal structure 2 in the shell 1 to prevent it from being offset during assembly or use. Such a design ensures the stability and reliability of the product structure and improves the overall performance of the product.

[0054] Further, in addition to the insulating plastic body 23 and the clamping ribs 21 and the positioning protrusions 22 arranged thereon, the internal structure 2 is further provided with a plurality of conductive terminals 24 extending along the plugging direction of the plug-in port 14. These conductive terminals 24 are arranged on the insulating plastic body 23 in the direction perpendicular to the plugging direction, ensuring the electrical isolation and mechanical stability between each conductive terminal 24. The design of the conductive terminals 24 is used to realize electrical connection with external devices, and the arrangement and spacing distance are carefully calculated to meet different electrical performance and mechanical strength requirements.

[0055] In summary, the embodiments of the utility model realize the following technical effects:

[0056] In the installation, the clamping rib 21 is in close contact with the blocking wall 121 of the shell 1, realizing stable connection; the positioning protrusion 22 is clamped into the positioning through slot 11, further enhancing the stability of the internal structure 2. The blocking wall 121 has good elastic performance, can maintain stable elastic force in the long-term use process, and is not prone to elastic fatigue, thereby effectively preventing the internal structure 2 from affecting the use effect and service life due to loosening.
