[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

Example

[0038] See Figures 2-6As shown, a DP port stable connector includes an inner shell 3, on which terminals 4 are mounted. An outer shell 5 is fitted over the inner shell 3, and the outer shell 5 can be made of metal or high-strength plastic to enhance the overall strength of the connector. The outer shell 5 has an outwardly protruding locking plate 51, which can be fixedly connected to the circuit board 1 by means of clips, screws, etc., providing stable support for the connector. A raised strip 6 is provided on one side of the inner shell 3 where the terminals 4 are located. The raised strip 6 is distributed on both sides of the terminals 4, and its height is higher than that of the terminals 4. During installation, the PCB board 2 contacts the raised strip 6, and the terminals 4 are suspended, preventing direct contact and damage between the terminals 4 and the PCB board 2 or other objects during operation. By adding the outer shell 5, the locking plate 51 provides effective support for the product during installation, solving the problem of window tilting during installation, making the product more stable during use, and improving the reliability and service life of the connector.

[0039] In this embodiment, the inner shell 3 is provided with an abutment surface 31, which is horizontally distributed and can provide a stable support reference. When the outer shell 5 is fitted onto the inner shell 3, the lower end of the outer shell 5 abuts against the abutment surface 31, which can effectively limit the installation position of the outer shell 5 and ensure that the outer shell 5 and the inner shell 3 are firmly assembled.

[0040] In this embodiment, the inner shell 3 and the outer shell 5 are connected by a snap-fit ​​mechanism. Specifically, the inner shell 3 has a snap-fit ​​groove symmetrically arranged along its central axis on one side. The shape of the snap-fit ​​groove can be a rectangle, trapezoid, or other common shapes, as long as it can stably engage with the snap-fit ​​block. The outer shell 5 is provided with a pair of cantilever arms 52, which have a certain degree of elasticity and can undergo slight deformation. The cantilever arms are provided with snap-fit ​​blocks corresponding to the snap-fit ​​grooves, and the size of the snap-fit ​​blocks is adapted to the snap-fit ​​grooves. During installation, the outer shell 5 is fitted onto the inner shell 3, and the cantilever arms bend inward under force. After the snap-fit ​​blocks enter the snap-fit ​​grooves, the cantilever arms return to their original shape, and the snap-fit ​​blocks and snap-fit ​​grooves are tightly engaged, achieving a stable connection between the inner shell 3 and the outer shell 5.

[0041] In this embodiment, there are two protrusions 6 arranged in parallel. These two protrusions 6 are symmetrically distributed along the central axis of the inner shell 3. This arrangement ensures uniform and stable support for the PCB board 2 during installation, effectively preventing connector tilting due to uneven support. Furthermore, the protrusions 6 are made of insulating rubber material, which has excellent insulation properties, preventing accidental contact between the terminals 4 and the PCB board 2 or other conductive components that could cause a short circuit. The insulating rubber material also possesses a certain degree of elasticity, which can buffer external impacts on the connector to some extent, further ensuring the stability of the connector structure.

[0042] In this embodiment, the locking plate 51 is positioned at a 90-degree angle to the outer shell body. This right-angle design ensures that the locking plate 51 makes tight and stable contact with the lower end face of the circuit board 1 during installation, providing reliable support for the connector and effectively preventing shaking or tilting after installation. The locking plate 51 is provided with mounting holes, which can be circular, elliptical, or other common shapes, and can be one or more in number. During installation, screws, rivets, or other fasteners can be passed through the mounting holes to fix the locking plate 51 to the circuit board 1, ensuring a secure and reliable connection between the connector and the circuit board 1.

[0043] In summary, the DP port stable connector provided by this utility model, through the addition of the protruding strip 6, effectively avoids terminal damage during operation. Furthermore, the addition of a housing 5, with a locking plate on the housing 5, provides stable support for the product, effectively limiting connector displacement and tilting, solving the problem of window tilting during product installation, and enhancing the product's stability during use.
