The embodiment of the utility model provides a photoelectric hybrid connector with calibration and fool-proof functions, as shown in fig. 1, comprising a male connector 1 and a female connector 2, comprising:

As shown in fig. 2, four accommodating chambers 112 are formed on the inner sides of four corners of the male end connector 1 adjacent to the square first outer shell 11; the accommodating cavity 112 is used for being empty or used for being embedded into the male end conductive terminal 12;

As shown in fig. 2 and 3, a female conductive terminal 233 that is in contact with the male conductive terminals 12 in the accommodating cavities 112 of the two corners above is provided above the ceramic abutment fixing collar 24 of the female connector 2, and/or a female conductive terminal 233 that is in contact with the male conductive terminals 12 in the accommodating cavities 112 of the two corners below is provided below the ceramic abutment fixing collar 24;

the inner side fitting positions of the first shell 11 of the male end connector 1 and the second shell 21 of the female end connector 2 are also respectively provided with a fool-proof protrusion 113 and a fool-proof groove 212; wherein the number of foolproof protrusions 113 is used to externally characterize the number of female conductive terminals 233.

As shown in fig. 1, four fool-proof protrusions 113 are fixedly arranged on four surfaces of the first outer shell 11; the foolproof protrusions 113 on the respective four corners are provided according to whether the accommodation cavities 112 inside the corresponding corners are provided with conductive terminals or not.

The foolproof protrusions 113 on the four corresponding corners are set according to whether the accommodating cavities 112 on the inner sides of the corresponding corners are provided with conductive terminals, specifically: if the accommodating cavity 112 inside the corresponding corner is not provided with a conductive terminal, the corresponding corner is not provided with a foolproof protrusion 113; or if the accommodation cavities 112 inside the corresponding corners are not provided with conductive terminals, foolproof protrusions 113 are provided on the corresponding corners.

In the embodiment of the present utility model, in order to achieve stability after the installation of the male conductive terminal 12, it is preferable that, as shown in fig. 4 and 5, the male conductive terminal 12 is a strip-shaped electrical terminal, and correspondingly, the accommodating cavity 112 is also a matching strip-shaped accommodating cavity 112. As shown in fig. 6, the strip-shaped electric terminal is one of a rectangular strip, a cylindrical strip, a triangular strip and an elliptical strip.

In the preferred implementation of the present utility model, considering that the corresponding male conductive terminal 12 has a strip-shaped structure, even if it is embedded in the accommodating cavity 112, the male conductive terminal is easily separated from the accommodating cavity, and the mounting is inconvenient, so, in connection with the embodiment of the present utility model, the conductive contact surface of the corresponding rectangular strip is considered to be good when the strip-shaped conductive terminal is the most common rectangular strip, and although the triangular strip can also use the ground as the contact surface, the triangular strip brings difficulty in manufacturing the corresponding accommodating cavity 112. As shown in fig. 7, the device specifically comprises a rectangular strip, and a semicircular arc columnar limit strip is integrally formed on one surface of the rectangular strip; wherein, a semi-circular arc column-shaped limit groove 1121 adapted to the semi-circular arc column-shaped limit bar is arranged at one side of the accommodating cavity 112. In this way, even the rectangular accommodating chamber 112 with one side opened as shown in fig. 7 can perform a good auxiliary installation stabilizing effect by the semicircular column stopper and the semicircular column stopper slot 1121. It should be noted that, in fig. 7, the relative positions of the pressing plate 14 and the accommodating cavity 112 are different from those of the pressing plate 14 and the accommodating cavity 112 in fig. 1, the pressing plate 14 is used for separating and assembling the first casing 11 and the second casing 21, the designs of the two relative positions are feasible, and the relative position relationship between the pressing plate 14 and the accommodating cavity 112 does not affect the function of the male conductive terminal 12. Also described above in the following fig. 8.

As shown in fig. 8 and 9, the female conductive terminal 233 of the female connector 2 has one end fixed to the power transmission assembly 23 and the other end passing through the guide through hole 211 formed in the second housing 21 to expose the abutting head of the female conductive terminal 233 above or below the ceramic abutting head fixing collar 24.

As a complete structural illustration of the power transmission assembly 23 in one example, as shown in fig. 10, the power transmission assembly 23 includes a columnar body 231 that interfaces with the ferrule assembly 22, and a positioning member 232 secured to the columnar body 231, the positioning member 232 being configured to be embedded in the female conductive terminal 233; the abutting head of the female conductive terminal 233 passes through the guiding through hole 211 on the inner wall of the second housing 21 to fix the female conductive terminal 233. In fig. 10, the positioning member 232 is different from the positioning member 232 in fig. 8 in that the surface of the positioning member 232 in fig. 8 is provided with an opening, and the positioning member in fig. 10 is not provided with an opening, and the presence or absence of the opening does not affect the female conductive terminal 233 to perform its function.

As shown in fig. 11, in addition to the implementation using the strip-shaped male end conductive terminal 12, the present utility model provides a more preferable alternative, in which the male end conductive terminal 12 is embodied as a gate-type electrical terminal that is limited on the rectangular boss 131 of the central shaft assembly 13 of the male end connector 1; after the center shaft assembly 13 and the first outer shell 11 are locked with each other, the door posts 122 of the door-shaped electric terminals beyond the end surface of the center shaft assembly 13 are embedded into the accommodating cavities 112 arranged on the corners of the first outer shell 11.

In order to achieve the technical characteristics of two motors of one door-shaped electric terminal, namely to achieve the same effect as the strip-shaped male-end conductive terminal 12, the utility model also provides a matched improved solution on the door-shaped electric terminal, as shown in fig. 12, wherein the door-shaped electric terminal is composed of an insulating door beam 121 and two door posts 122 which are respectively fixed on the insulating door beam 121 and are electrically isolated from each other; wherein, each of the two door posts 122 comprises a welding area, and the welding areas are arranged on the insulating door beam 121 in a staggered manner.

In the embodiments of the present utility model, in order to effectively achieve compatibility, the abutment of the female conductive terminal 233 is located inside and outside of each other, respectively, as compared to the abutment of the male conductive terminal 12.

The conductive terminals 12 at the positive ends of the four accommodating cavities 112 form a power supply electrode and a signal transmission electrode in pairs; or only two adjacent/opposite male-end conductive terminals 12 are distributed in the four accommodating cavities 112 to form a power supply electrode; or two sets of horizontally adjacent male end conductive terminals 12 are respectively used as one electrode to form a power supply electrode.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
