[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-5 As shown, this utility model provides a connector whose structure mainly includes a housing 1, an insulating inner core 2, and several terminals 3. When the three are assembled, the insulating inner core 2 is installed inside the housing 1, and the terminals 3 are inserted into and fixed inside the insulating inner core 2. This structure ensures the stability of the internal structure of the connector and the reliability of the electrical connection.

[0030] The housing 1 consists of a first outer shell 101 and a second outer shell 102, with one end of each shell fitting together to clamp and fix the insulating inner core 2. The outer side of the first outer shell 101 has several pressure plates 111 extending towards the second outer shell 102. These pressure plates 111 not only enhance the structural strength of the housing but also achieve a tight assembly of the housing by pressing and fixing the second outer shell 102. Furthermore, the first outer shell 101 and the second outer shell 102 are further locked and fixed by several detachable locking elements 4, ensuring that the connector will not loosen due to external force during use.

[0031] To better secure the insulating core 2, the second outer shell 102 has a groove 123 at the end near the first outer shell 101 that matches the insulating core 2. This allows one end of the insulating core 2 to be easily inserted into the groove 123 for fixation, thereby improving the installation efficiency and stability of the insulating core. Simultaneously, the other end of the insulating core 2 passes through the first outer shell 101 and extends outwards, while the end of the first outer shell 101 away from the second outer shell 102 has an extension 112 that fits and fixes the insulating core 2 to the outside. The extension 112 not only further secures the insulating core 2 but also provides greater convenience for external connection of the connector.

[0032] The pressure plates 111 are distributed on the outer side of the second outer shell 102, and can simultaneously press and fix the second outer shell 102 towards the center. This not only enhances the overall stability of the shell, but also allows the pressure plates 111 to better adapt to second outer shells 102 of different shapes and sizes. In addition, the second outer shell 102 is provided with several notches 124 corresponding to the positions of the pressure plates 111, and the end of the pressure plate 111 near the second outer shell 102 is provided with a limiting notch 113 that engages and is fixed with the corresponding notch 124. This engaging structure further improves the assembly efficiency and stability of the shell.

[0033] When the locking member 4 is locked, in order to facilitate operation, both ends of the first housing 101 and the second housing 102 are provided with aligned locking holes 1122. The locking member 4 can pass through these two locking holes 1122 at the same time for locking and fixing, which not only simplifies the assembly process of the connector, but also improves the reliability and durability of the locking structure.

[0034] One end of terminal 3 extends outward through the second housing 102 to facilitate connection with external equipment or cables. To protect these outwardly extending terminals 3, the end of the second housing 102 away from the first housing 101 is provided with two protrusions 121 distributed on both sides of the terminals 3. A removable cover plate 122 is connected between these two protrusions 121. The cover plate can simultaneously cover all outwardly extending terminals 3, effectively preventing the terminals 3 from being damaged by impact.

[0035] The protrusion 121 has a locking hole 125 in the middle, and the two sides of the cover plate 122 are connected to barbs 126 that extend into the locking hole 125 for fixation. This locking structure not only makes the installation and removal of the cover plate more convenient and quick, but also improves the connection strength between the cover plate and the protrusion.

[0036] The insulating inner core 2 has several insertion holes 201 at one end that passes through the first outer shell 101. The insertion holes 201 are connected to corresponding terminals 3 inside the insulating inner core 2. This allows external devices or cables to be electrically connected to the terminals 3 through the insertion holes, thereby realizing the electrical signal transmission function of the connector.

[0037] Compared with the prior art, the connector provided by the technical scheme can be pre-fixed through the pressing piece 111 connected between the two housings to correct and align the positions of the two housings, facilitate locking and fixing by the locking piece 4, and additionally, the cover plate 122 provided at the outer extension end of the upper terminal 3 of the connector can protect all the terminals 3, effectively protecting the terminals 3 on the connector from being collided and avoiding damage of the terminals 3.

[0038] It is obvious for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the foregoing description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced in the present application, and any reference signs in the claims should not be regarded as limiting the claims involved.
