[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, the utility model provides a fool-proof connector, which is an electronic connector mainly used for transmitting high-frequency signals. Its structure mainly includes a female end component 1 and a male end component 2 that are directly plugged into each other. The entire connector is mainly composed of the female end component 1 and the male end component 2. After the female end component 1 is connected to the male end component 2, the internal RF plug 104 is inserted into the RF socket 204 to achieve signal transmission. In the process of plugging the female end component 1 and the male end component 2, the technology provided by the technical solution can effectively form a fool-proof connection structure, which helps to protect the internal RF plug 104 and avoid blind plugging to damage the connector.

[0025] Regarding the female end component 1, the surface of the female end component 1 is a female end shell 101 with an internal hollow structure and an open end. A female end connector 102 for plugging and fixing with the male end component 2 is assembled in the female end shell 101. The female end connector 102 is aligned with the opening of the female end shell 101. During assembly, a plurality of female end fixing strips 105 for clamping and fixing with the female end connector 102 are added to the inner wall of the female end shell 101. However, a groove 103 for convenient clamping is provided on the side of the female end connector 102 facing outward to plug with the male end component 2. An axially protruding radio frequency plug 104 is assembled in the middle of the groove 103. The radio frequency plug 104 only protrudes in the groove 103 and does not extend outside the female end shell 101. The radio frequency plug 104 can be better protected by the groove 103.

[0026] Regarding the male end component 2, the surface of the male end component 2 is a male end shell 201 with an internal hollow structure and an open end. A male end connector 202 for plugging and fixing with the female end component 1 is assembled in the male end shell 201. The male end connector 202 is aligned with the opening of the male end shell 201. During assembly, a number of male end fixing strips 205 that are clamped and fixed with the male end connector 202 are added to the inner wall of the male end shell 201. However, the male end connector 202 is provided with a protrusion 203 that is clamped with the groove 103 of the female end connector 102 on the side facing outward to plug with the female end component 1, and a radio frequency socket 204 that is axially plugged with the radio frequency plug 104 is embedded in the middle of the protrusion 203. At this time, multiple groups of radio frequency plugs 104 that are plugged and connected with the radio frequency sockets 204 can also be arranged inside the connector.

[0027] When the female component 1 and the male component 2 are plugged into each other, the raised protrusion 203 of the male connector 202 is inserted into the groove 103 of the female connector 102, and an anti-foolproofing portion 207 and a matching anti-foolproofing slot 107 are added to the connection between the two to prevent blind plugging and causing wrong direction. The anti-foolproofing slot 107 is arranged on the surface of the female connector 102 and is connected to the groove 103 at the same time. The anti-foolproofing slot 107 also adopts a structure in which the inner diameter gradually increases from the bottom to the open end. Correspondingly, the anti-foolproofing portion 207 is arranged at one end of the male connector 202 and is inserted into the anti-foolproofing slot 107 simultaneously with the insertion of the raised portion 203 into the groove 103. At this time, the size of the anti-foolproofing portion 207 matches the anti-foolproofing slot 107, that is, the anti-foolproofing portion 207 is inserted first at one end with a smaller diameter. This structure avoids blind plugging and is also convenient for automatic position correction to facilitate plug-in connection.

[0028] It should be further explained that in order to prevent the female connector 102 from falling off after being connected to the male connector 202, patches 3 that fit together after being raised are added to the connection between the female shell 101 and the male shell 201. The two patches 3 are fixed to prevent them from falling off after connection. After the two patches 3 are fitted together, the user can insert four detachable screws 4 to tighten and strengthen the fixation in all directions. During assembly, the screws 4 are inserted from one end of the female component 1. In order to better assemble the screws 4, a fixing nut 5 for conveniently locking the end of the screw 4 is integrally connected to the patch 3 of the male component 2. In addition, a sealing ring 6 can be clamped between the two patches 5 to enhance the sealing after connection, which can achieve better waterproof and dustproof effects.

[0029] Conductive wires that are conductive to the interior are provided at the ends of the female housing 101 and the male housing 201 that are away from the mating. Specifically, the female housing 101 is connected to a female conductor 106 that extends outward and is conductive to the internal RF plug 104, while the male housing 201 is connected to a male conductor 206 that extends outward and is conductive to the internal RF socket 204.

[0030] Compared with the traditional technology, the connector provided by the present technical solution has an anti-foolproof portion 207 and a matching anti-foolproof slot 107 at the connection point to prevent blind insertion when the female connector 102 and the male connector 202 are plugged together. At the same time, the anti-foolproof portion 207 adopts a structure in which the end with a smaller outer diameter is inserted first, which not only has a good anti-foolproof effect, but also realizes the effect of automatically calibrating the position during insertion, effectively extending the service life of the connector and making it more practical.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
