It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0021] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, and fixing should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] Please refer to Figure 1-3 As shown, a connector with fool-proof terminals includes a base 1, a shell 2 detachably plugged into the base 1, and a through hole 4 for pressing and fixing the shell 2 on the base 1; wherein, a welding plate rivet assembly 3 is provided on one side of the through hole 4, and the welding plate rivet assembly 3 is fixedly connected to a wire nose 15 plugged into the base 1 through a nut, and the welding plate rivet assembly 3 includes a welding plate terminal 301 and a guide bar 302, and the wire nose 15 is placed between the shell 2 and the base 1.

[0024] Specifically, the shell is detachably connected to the base, which facilitates the installation of the wire nose. The welding plate rivet assembly is separated from the base and the shell, so that when replacing the interface, there is no need to remove the welding plate rivet assembly from the PCB board, thereby protecting the PCB board from damage and reducing the cost of use.

[0025] First, separate the connector's plastic housing and base from the soldering plate terminals. Solder the soldering plate terminals to the PCB. The insulating housing is then locked onto the chassis's exterior panel, and the connector and soldering plate terminals are assembled. When the connector needs to be replaced, only the insulating housing needs to be replaced, while the soldering plate terminals remain attached to the PCB. This reduces costs and prevents damage to the PCB during removal. Furthermore, the integrated design of the soldering plate terminals and the guide bar makes them even more convenient to use.

[0026] In this embodiment, the upper end of the through hole 4 is opened so that the wire nose can be inserted into the base 1 from the upper end opening of the through hole 4 .

[0027] Specifically, the base is designed with a through hole, and the shell is inserted into the base from an opening on one side. The upper opening of the through hole is then designed so that the wire nose can be inserted into the base. The wire nose is stuck between the base and the shell, and then fixed and installed with a nut.

[0028] In this embodiment, a plurality of slots 5 are horizontally provided on both sides of the through hole 4 , and plug-in portions 6 adapted to the slots 5 are provided on both sides of the outer wall of the housing 2 .

[0029] Specifically, the cooperation between the slot and the plug-in portion can make the connection between the shell and the base more stable and can also play a limiting role to prevent the shell from being displaced in the through hole of the base.

[0030] In this embodiment, fixing portions 7 are provided on both sides of the side walls of the housing 2 that are in contact with the wire nose.

[0031] Specifically, the fixing portion fixes the wire nose, and the fixing portions on both sides clamp the wire nose on the housing to prevent the wire nose from shaking. Elastic buckles can also be provided at the ends of the fixing portions to further fix the wire nose.

[0032] In this embodiment, the fixing portion 7 is disposed at the upper end portion of the housing 2 , and a baffle 8 is provided at the lower portion of the fixing portion 7 .

[0033] Specifically, the baffle below the fixing portion is used to clamp and fix the lower end of the line nose.

[0034] In this embodiment, the length of the fixing portion 7 is longer than that of the baffle 8 , and abutting portions 9 abutting against the bottom of the fixing portion 7 are provided on both sides of the wire nose.

[0035] Specifically, the abutting portion provided on the wire nose abuts against the bottom of the fixing portion, and the abutting portion can prevent the wire nose from being drawn out of the housing, thereby playing a role of limiting and fixing.

[0036] In this embodiment, the housing 2 and the plate rivet assembly 3 are respectively provided with a first connection hole 10 and a second connection hole 11. The second connection hole 11 is located on the guide bar 302, and the wire nose is provided with a third connection hole 12. The first, second, and third connection holes cooperate with nuts to securely assemble the plate rivet assembly, the base, and the housing.

[0037] In this embodiment, slots 13 are provided on both sides of the through hole 4 and one end of the welding plate riveting assembly 3 , and the guide bar 302 is placed in the slots 13 .

[0038] Specifically, the welding plate rivet assembly is inserted from the other side of the base through hole, the guide bar is placed in the slot, and then fixed to the base with a nut.

[0039] In this embodiment, a stop plate 14 is provided at the bottom of one end of the housing 2 .

[0040] Specifically, the abutment plate can prevent the wire nose from being excessively inserted into the base, thereby playing a limiting role.

[0041] Assembly method: Fix the welding plate riveting assembly to the base through nuts, then solder the welding plate terminals to the PCB, insert the wire nose into the base from the upper opening, and then insert the shell into the base from the other end of the through hole, clamp the wire nose between the base and it, and then lock it with nuts to complete the installation of the connector.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
