The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

An embodiment of the present utility model provides an optoelectronic hybrid connector, as shown in fig. 1, including a male connector 1 and a female connector 2, and is characterized by comprising:

four accommodating cavities 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 receiving cavity 112 is for being empty or for being embedded in the male conductive terminal 12 (as shown in fig. 2);

The ceramic abutment 24 of the female connector 2 is provided with a female conductive terminal 233 (as shown in fig. 3) abutting against the male conductive terminals 12 in the accommodating cavities 112 at two corners above the fixing collar 25, and/or a female conductive terminal 233 abutting against the male conductive terminals 12 in the accommodating cavities 112 at two corners below is provided below the fixing collar 25 of the ceramic abutment 24. The structure shown in fig. 3 is a schematic diagram showing the effect of arranging the female conductive terminals 233 on the upper and lower surfaces of the corresponding fixing collar 25.

By the embodiment of the utility model, the photoelectric hybrid connector which is easy to assemble and has high compatibility with the existing connector is realized. The compatibility is shown in that the conductive terminals of the male connector 1 and the female connector 2 can be directly used as a conventional optical connector under the condition of no power connection; moreover, even if one of the male connector 1 and the female connector 2 is an existing connector which is not laid out with conductive terminals, the connector fitting with the other side improved with the conductive terminals of the present utility model is not affected.

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 module 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 24 fixing collar 25.

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 second ferrule assembly 22, and a positioning member 232 fixed 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 a strip-shaped male end conductive terminal 12, the present utility model also provides a better alternative, in which the male end conductive terminal 12 is in particular a gate-type electrical terminal that is retained on a 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.
